Explanation Of Sewing Quality And Performance Of Electronic Flat Nose Keyhole Machine

A good keyhole sewing machine should not only be perfect and stable. sewing The stitch is also efficient and easy to operate. It can widely adapt to different materials and at the same time be environmentally friendly and energy efficient. The electronic flat head keyhole machine accords with all the characteristics mentioned above, so it has become a hot spot in the market in recent years.

The electronic flat head keyhole machine has achieved computer control because of cloth feeding, pin setting, cutting, cutting, cutting, and presser lifting mechanism. Compared with mechanical flat nose keyhole machine, the electronic sewing machine has greatly improved the quality of sewing and production efficiency. There are generally two derivative machines for this series of products, one is used for keyholes in woven fabrics such as shirts, work clothes and women's clothing. The maximum lock hole length of cbh-1790 electronic flat head keyhole machine of the seam sewing machine can reach 170 millimeters.

　 Sewing quality

When the machine is running at high speed, it is easy to affect the stability and accuracy of sewing because of the vibration generated by the rotation of the upper shaft of the needle bar. It can reduce the impact of vibration. The cbh-1790 electronic flat nose keyhole machine of the sewing machine heavy industry has effectively overcome the gravitational effect of the take-up rod at the top of the needle bar under high speed rotation by strengthening the fixing device, and ensures the beautiful appearance of the stitches.

The accuracy of cutting operation directly affects the quality of sewing. The cutting action of electronic flat nose keyhole machine is driven by electromagnet, which makes cloth cutting more accurate. The key can be stopped by cutting the knife, and the cutting operation can be carried out without slowing down. The cutter will not break the stitches, and the spacing between the knives will not change, thus ensuring the sewing quality. It will not cause bad knife or bad return. In addition, by using the new tangent mechanism, the residual quantity of the offline thread is shortened, and the needle jumping can be prevented at the end of sewing. Cutter operation can be generally divided into four types: front, middle, back and middle.

Whether the bottom seam is strong will directly affect the sewing effect of knitted fabric. Electronic flat nose keyhole machine There are many kinds of sutures and stitches, and they can also be stitched together. Take the brother he-800a electronic flat head buttonhole machine as an example, it has four modes: rectangle, sawing, cross stitching and Z shaped sewing. If the front stitch is not formed on the line, the Z type sewing under special circumstances can not be carried out normally. In this case, the buttonhole that is cut by the cutter must be stitched together in advance. The fabric must be flattened before sewing, so that the appearance of the keyhole will be more beautiful.

　 Operational performance

All data set and selection of electronic flat nose keyhole machine can be realized by operation control panel. Random are usually equipped with twenty or thirty tricks, you can remember the largest 99 patterns. Some brands also have program menu on the back of the operation, such as parameter list, program instruction and error code table, which facilitate sewing operator operation.

The presser foot of the electronic flat eye keyhole machine is driven by a pulse motor, and the height can be adjusted according to requirements. This simplifies the insertion and movement of cloth and reduces the labor intensity of sewing workers. In addition, because the lifting foot only rises when the height is needed, the time of rise and fall is shortened, thereby saving the auxiliary time and increasing the output. The machine can also switch between 1 connecting pedals and 2 connecting pedals to facilitate the determination of sewing positions or intermediate stops. In addition, the foot lifting height can be set arbitrarily, and the lifting capacity of the presser foot can reach up to 17 millimeters by reversing the lifting needle function.

In order to make sewing operators more convenient, the electronic flat eye keyhole machine performance Many improvements have been made in the form design. For example, enlarging the platform of the presser foot, so that the width of the left side of the needle point of the machine tool can be greatly reduced, and the cloth can be placed conveniently. For example, by installing the auxiliary machine (standard accessory), the placement of cloth is improved. Besides, the needle is placed in the center of the machine tool to facilitate the location. In order to make threading easier, the needle bar of this series can move to the right end.
