Introduction And Maintenance Of Phoenix Eye Machine

< p > phoenix eye machine. It is called round head keyhole machine in writing.

The so-called "round head" means the front end of the buttonhole is circular.

The button hole is characterized by its beautiful shape and uniform track.

Round head keyhole machine generally adopts oscillating needle bar, double bending needle, double fork needle hook wire, double line stitched compound chain trace.

< /p >

< p > in China, the commonly used round head keyhole machines are the GM1-1 round head keyhole machine of Shanghai Liming machine repair factory, the GY1-1 phoenix eye machine of Guangzhou sewing industry company, the SINGER 299U 299U 231 type phoenix eye machine, and the American company's 101 and the phoenix eye machine.

The round nose keyhole machines manufactured by various manufacturers are different in shape and shape, but from the point of view of machine structure, they can basically be divided into two categories: one is the German type GY1-1, the Chinese type of Southern China phoenix eye machine, the GM1-1 type Fung eye machine of dawn brand, and the other is the 299U model of SINGER company of the United States.

These round head keyhole machines rely on mechanical control of various movements, and their internal mechanisms overlap and adjust.

In order to enable learners to better understand the performance of the machine, help maintenance department students to further grasp the structure of the machine so as to keep a clear head in use, maintenance, adjustment and maintenance, clear thinking, and achieve better and faster maintenance results.

Next, we take the existing Southern China brand GY1-1 phoenix eye machine as the blueprint, and then analyze the other models to study the structure, principle, use, adjustment and maintenance of the round nose keyhole machine.

< /p >

< p > round head keyhole machine is mainly used for sewing buttonholes in all kinds of medium heavy materials such as knitted, cotton and woolen fabrics.

In general, it can be cut first and then sewn. It can also be adjusted to stitch first and then to stitch buttonholes.

By adjusting the cam, the buttonholes with different sizes and shapes can be locked out.

It takes only 5-8 seconds to sew one button hole. It is a special machine for producing high efficiency sewing knobs.

< /p >

< p > GY1-1 < a href= "http://cailiao.sjfzxm.com/Matertial/show/machine_index.aspx" > phoenix eye machine < /a > is driven by motor, adopts cam picking line, swinging needle bar, double bending needle.

Double fork hook wire, double thread stitch compound chain trace.

The upper and lower movements of the needle bar are driven by helical gears, and the ratio of the active helical gear to the passive gear is 2:1.

Feeding is worm wheel drive.

Through the curve grooves on the worm wheel and the curve of the round head cam, the skateboards (worktables) move continuously and intermittently before and after, so that the corresponding swings are carried out, and the two speed running structure is adopted.

The main technical parameters are: < /p >

< p > spindle speed: 700 R / min < /p >

< p > sewing speed: 1400 needles / points < /p >.

< p > needle density: 1 to 2.1 mm < /p >.

< p > the width of the pendulum needle is 1.4 to 3.5 millimeters < /p >.

< p > buttonhole length: 15, 20, 22 mm < /p >.

< p > > 10~38 mm (including small round head) < /p >.

< p > maximum thickness of seam material: 4 mm < /p >

< p > needle stroke: 34.3 mm < /p >.

< p > machine specifications: 96 x 14; 96 x 16; 96 x 18 < /p >

< p > < strong > operation of the phoenix eye machine < /strong > < /p >

< p > in this section, we mainly introduce the operation methods of the phoenix eye machine, the shape of buttonholes, the adjustment of button holes, such as the installation of machine needles, the way of thread, the length of buttonholes, the density of stitches, the width of horizontal rows, the spacing of horizontal columns, the cutting knives, the pressers and so on.

< /p >

< p > < strong > 1. The installation of machine needles < /strong > < /p >

< p > Southern China GY1-1 round eye keyhole machine usually uses 96 x 14, 96 x 16, 96 x 18 or GV3 type (16 * 231 type).

The DB x 1 machine needle of the flat car is also a commonly used needle for phoenix eye machine.

When selecting the needle, the size of the needle must be determined according to the thickness of the suture. The suture should be smoothed through the needle eye of the needle.

Rough stitching, uneven thickness, or tighten through the needle needles will cause poor sewing.

< /p >

< p > when the machine needle is installed, the side of the needle must be directed toward the side of the needle bar with a small clamp device. At the same time, the needle should be raised to the top as far as possible in the pinhole, then tighten the fastening screws of the machine needle.

When we learn machine repair, we should know that the needle of the needle is always in the direction of the hook or thread picking.

< /p >

< p > < strong > two, suture wearing < /strong > < /p >

< p > the choice of suture is very important for the smooth operation of sewing and the quality of buttonhole sewing.

The bottom line of the phoenix eye machine is usually made of tough, soft, smooth cotton thread No. 30~60 or 10~20 silk thread.

When using cotton thread keyhole, the bottom line should be slightly tighter than the surface line.

When using silk keyhole, the bottom line should be slightly thicker than the surface line, so the stitches of buttonholes are more beautiful.

Inserting thread is used to enhance the firmness and beauty of buttonholes. It usually uses 0.4 to 0.8 millimeters of soft and smooth cotton thread, and the right line twisting is better.

< /p >

The threading method of < p > < strong > GY1-1 round head keyhole machine is shown below: < /strong > /p >

< p > 1, the way to wear the face line is drawn out of the wire frame, and from the front (operator direction) into the lower hole of the passing column, bypassing the line post and then going forward through the upper hole, then bypassing the pre spool shaft before the clamp device, and then winding into the clamping plate of the clamping device.

Then, from the bottom up to the thread hole of the picking rod, and then enter the shaft hole at the top of the needle bar (with the wire drawing wire stretched out from the notch below the needle bar, the surface line will be pulled down; some mechanic workers will also put a line in the gap below the needle bar, then use the mouth to suck up the suture, and then connect the two wires, but this prevents the oil suction in the needle bar.

The surface line is pulled out from the notch below the needle bar and wound around the small clamping plate in the needle bar, and then penetrated into the pinhole of the machine to pull out about 80 millimeters long thread ends.

< /p >

< p > 2, bottom line wear method, the bottom line is drawn from the wire rack, from top to bottom, through the hole passing through the base of the chassis, and then penetrated into the underpass hole and the coil.

The bottom line is pulled out from the bottom of the wire hook shaft by a wire drawing steel wire, through the bent pin seat over the wire pin, around the bending needle holder, the clamping plate and the lower flat clamp wire plate.

Through the thread picking spring, the curved needle seat through the hole, the bending needle frame left pressure plate through the line hole, and the bent needle rack left hook needle cross hole, and then from the curved needle seat throat plate (needle throat) leads the approximately 80 millimeter long thread head.

< /p >

< p > 3, inserting thread into the left side of the base through the line hole, using the lead wire to insert the thread into the long thread embedding catheter, and then from the left to the right into the machine board embedded guide plate, from the front forward through the bent needle seat over the wiring board, leading the bending needle seat throat plate, leaving 80 millimeters long.

< p > < strong > three, machine operation < /strong > < /p >.

< p > the operation method of round head keyhole machine is very simple.

But in the process of operation, we should also pay attention to some problems, which will help us to operate more efficiently.

< /p >

< p > 1, machine belt wheel phoenix eye machine has about two belt drive wheels: the left side is the high speed wheel, the right side is the needle wheel (right-hand wheel).

They are driven by motor flywheels.

The motor has two driving belt flywheels, and the right flywheel of the motor is driven by the round belt to drive the right-hand wheel of the machine to rotate counterclockwise.

Its speed is 700 rpm.

The left flywheel of the motor is driven by the cross round belt to drive the left high speed wheel to rotate counterclockwise (viewed from the left side).

< /p >

< p > 2, the placement of sewing materials. When we wear the stitches, we will place the < a href= "http://cailiao.sjfzxm.com/Matertial/show/machine_index.aspx" > the seam > /a >. We should pay attention to that the surface of the buttonhole is locked on the bottom of the buttonhole, and the bottom seam is locked on the front side of the buttonhole, so when we place the sewing material, we should place the bottom face of the seam upwards, and mark the knob on the sewing material, then put it under the presser foot.

Pull down the foot wrench (if the operation is skillful, press the start button and press the foot automatically to sew the material).

< /p >

< p > 3, when sewing starts, press the "ON" button on the power box of the machine first, then push the power switch and the handle of the round head forward, and the machine is energized, but the handwheel and the high speed wheel are idling at this time.

The machine starts working only after pressing the start button.

When the button hole is locked, the worktable returns to its original position, and the presser automatically loosens the sewing material.

The operator can pinch the end of the buttonhole by hand and pull the sewing material out.

Then clip the thread on the clipping board and cut it on the secant blade.

< /p >

< p > < strong > four, adjustment of suture tension < /strong > < /p >

< p > the tightness of the bottom and the surface line is adjusted by the elastic nut on the bottom line clamp, which is better regulated.

Usually the thread clamp nut is rotated clockwise, the seam tension becomes larger and the stitch tighter. The counterclockwise rotation nut reduces the tension of the suture and looser the stitch.

The tension adjustment of the suture is carried out according to the thickness of the suture and the thickness of the material.

Properly adjusted, the buttonholes have uniform, beautiful and strong stitches.

If the suture tension is too large or too small, it will make the buttonhole line trace shrink and break or make the buttonhole track loose.

The use of polyester "nylon" and other elastic suture, the tension of the surface should be reduced as far as possible, otherwise there will be jumping needle phenomenon.

The standard of tightness of bottom and surface line is shown.

< /p >

< p > < strong > five, the shape of buttonhole is < /strong > /p >

The shape and size of the button hole of the round head keyhole machine are determined by the button hole cam and the block cutting mode. < p >

If you want to lock the knobs with different shapes and sizes, you must replace the corresponding button Kong Tulun, cutting, cutting and moving positioning rules according to the required pattern.

< /p >

< p > generally, there are two kinds of knobs: tail opening and closing.

So the buttonhole cam also has the opening and closing ends.

When the button hole cam is changed, the machine should be placed in the final position (when the table is dropped to the positioning plate just to locate the roller).

Then the original button hole cam is put up and replaced with the required button hole cam. When the installation is installed, the positioning of the button hole cam should also be aligned with the positioning pin on the axis, and the button hole cam is pressed down.

< /p >

< p > < strong > six, button hole length adjustment < /strong > /p >

< p > the length of buttonhole is adjusted by changing the position of the positioning gauge on the seat.

When adjusting, unscrew the length and adjust the fastening screws of the square head, then adjust the position of the positioning gauge.

Move forward (toward operator direction) button hole length grows, move backward, buttonhole length shortens.

The length of the buttonhole can be determined according to the length sign, and there is a phoenix eye on the positioning gauge. There is a horizontal line at the end, and the length of the horizontal line can be aligned. The number indicates the length of the button hole.

The length of the general buttonhole is 10~38 millimeters, the length of the tail tail is 15, 20, and 22 mm.

After fixing the length of the buttonhole, the square head screw of the length adjusting seat is then locked.

< /p >

< p > < strong > seven, cutting length and cutting pressure adjustment < /strong > /p >

< p > 1, the cutting length of buttonholes is determined by cutting blocks.

If the buttonhole length is to be adjusted, the corresponding length of the chop must be replaced.

The cutter usually changes the corresponding cutter after the change of the shape of the button hole.

The installation of cutter must be tested on the pattern, and the cutter must be indentation in the needle hole of the pattern.

If left or right, loosen the three screws on the cutter seat and move the cutter seat.

Then fix the first positioning plate and the rear positioning plate.

< /p >

< p > 2, the size of the cutting pressure is achieved by adjusting the pressure nut.

If the pressure adjusting nut is rotated clockwise, the cutting pressure is enhanced, otherwise the cutting pressure decreases.

When the tool block is installed, the cutter should grow about 1 millimeters.

But be careful not to strain too much pressure.

When the chopping block is pressed down, the worm shaft manual crank should still be able to be easily moved.

If the worm shaft has been rocked, it has been laborious and can not be cut, so it is necessary to repair the cut or cutter.

Too much cutting pressure can cause damage to the parts.

If the seam material can not be cut completely before and after, the eccentric adjusting screw can be rotated.

< /p >

< p > < strong > eight, buttonhole horizontal adjustment < /strong > < /p >

< p > 1, buttonhole width can be adjusted by adjusting the butterfly nut on the rack, and the upper pull rod moves upward along the arc groove of the horizontal adjusting rack, and the width of the pverse column is reduced, moving downward, and the width of the pverse column increases.

The width of the left and right columns of the general knob is equal.

< /p >

< p > 2, row spacing, that is, the center distance between buttonholes, is the distance between the left and right columns.

The adjusting part is arranged on the adjusting screw of the needle shaft horizontal axis, and there are two upper and lower adjusting spacing nuts. If the spacing between the columns is increased, the nut on the adjusting screw can be loosed loosely, and the spacing nut is tightened. If you want to narrow the horizontal row spacing, you can break the spacing screw nut and tighten the adjusting spacing nut on the screw pin.

The adjustment of horizontal spacing is usually based on the location of the cutter, so that the cutter can not be cut off when the cutter is cut off.

< /p >

< p > < strong > nine, foot insurance and stopping needle < /strong > /p >

< p > during the operation of the machine, if the section line can immediately press the foot pressing safety button by hand, the pressure foot can be automatically relaxed to change the position of the sewing material.

Wear the noodles and then re stitch.

If the a href= "http://cailiao.sjfzxm.com/Matertial/show/machine_index.aspx" > bottom line < /a > is broken, the seam material should be taken out and the bottom line repaired before repatching.

If the sewing material can not be retained with pinholes, the needle bar must be stopped after the thread is broken, so the needle bar must be pulled. At this point, the needle bar will stop moving.

After wearing the thread, shake the handle on the edge of the high speed wheel, make the sewing table move, move to the position where the sewing material needs seams, then rotate the needle hand wheel (right-hand wheel), so that the needle is inserted into the stitch line of the seam, and the machine is started again.

< /p >

< p > < strong > ten, adjustment of button hole distance < /strong > < /p >

< p > button hole distance, that is, the stitch density of buttonholes should be adjusted according to the thickness of the sutures and the specifications of buttonholes.

When adjusting, it is possible to unscrew the needle spacing density pull rod square nut, move the forked needle distance density rod along the worm shaft ratchet groove forward (operator direction), then move the needle from the opposite direction, then tighten the square nut after the needle spacing is fixed.

This is the adjustment of the overall density of the buttonhole.

In addition, the stitch density of the round head can be adjusted by the position of the mobile head density gauge.
