The Electronic Sewing Machine Creates Complex Embroidery Patterns.

No

The world may be another look.

Like cars, cotton gin and countless other innovations over the past 300 years, sewing machines have undertaken a time-consuming and arduous task and made it quick and simple.

The invention of mechanized sewing machines made manufacturers suddenly able to produce large quantities of high quality clothing at the lowest cost.

In fact, the automatic stitching mechanism of the core part of the sewing machine is unbelievable, but the machine driving this mechanism is very precise. It needs the cooperation of gears, pulleys and motors to properly perform functions.

After a thorough understanding of sewing machines, you will find that it is one of the most ingenious and creative tools invented by human beings.

There are hundreds of sewing machines in the market. In the low-end products, there are traditional basic electric designs, which are suitable for occasional household use. In high-end products, there are complex designs that can be connected to computers.

。

There are many types of sewing machines available in textile companies, including improved models for sewing certain products.

Most sewing machines have the same basic principles.

In the simplest hand stitching, the stitch thread a thread in the small eye at the end of the needle, then pass the needle thread through two pieces of fabric, one side to the other, and then the other side.

In this way, the needles move in and out of the fabric and stitch them together.

Although this is very simple for manual work, it is extremely difficult to pull it by machine.

The machine needs to release the needle on the side of the fabric and catch it again on the other side.

Then, it needs to pull loose lines out of the fabric, rotate the needle direction, and repeat all steps in the opposite direction.

This process is too complicated for a simple machine, and it is not practical, and even for manual work, it can only be used with shorter lines.

On the contrary, the sewing machine only needs to pass the needle part through the fabric.

On the needle, the needle is behind the tip, not at the end of the needle.

The needle is fixed on the needle bar, and the needle bar is driven by the motor through a series of gears and cams.

When the tip of the needle passes through the fabric, it pulls out a small coil on the other side.

A device underneath the fabric will grab the loop and wrap it on another thread or another coil on the same line.

Lock catch and chain

We understand that the core of sewing machine is coil stitching.

In fact, there are many different types of coils, and their principles are slightly different.

The simplest coil stitching is chain stitching.

If you want to sew out the chain suture, sewing the opportunity online and ring it with the same length of thread.

The fabric is placed on a metal plate under the needle and fixed with a presser foot.

At the beginning of each stitch, the needle passes through the fabric and pulls out a coil.

A device for making coils holds the coil before the needle pulls out, and the device synchronously moves with the needle.

Once the fabric is pulled out, the cloth feeding device will pull the fabric forward.

When the needle passes through the fabric again, the new coil will go directly through the middle of the first coil.

The coil device will catch the wire again and make a coil around the next coil.

In this way, each coil will fix the next coil in place.

The main advantage of chain stitching is that it can sew very quickly.

However, it is not particularly strong. If the ends of the thread are released, the whole sewing will be loose.

The two connecting rods synchronize, let the cloth feeding teeth press on the fabric, move it forward, and then release the fabric downward.

Then, before pressing the fabric repeat cycle again, the feeding tooth will be moved back to the original position.

The motor is controlled by pedals, and the speed change can be easily realized by the sewing machine.

The advantage of this design is to connect all these components together. When you pedal the motor, the motor will drive all the processes at the same speed.

No matter how fast the motor turns, this process can always be absolutely synchronized.

Most modern sewing machines are much more flexible; they can form multiple pins and sometimes even produce complex patterns.

The working principle is slightly different from high-end home sewing machine built-in computer, and small monitor display for easy operation.

In these sewing machines, computers directly control a number of different motors.

These motors can move the needle bar, pressing plate, feeding tooth and other sewing machine elements accurately.

With this fine control, it can produce hundreds of different stitches.

In a specific stitch style, the computer enables the motor to drive the needle bar up and down and the left and right movements according to the exact speed.

In general, computer programs with different pins are stored in removable storage disks or tapes.

You can also connect the sewing machine computer to PC to download patterns directly from the Internet.

Some electronic sewing machines can also create complex embroidery patterns.

These sewing machines have a motorized working area where they are placed under the needle assembly.

They also have a series of sensors that can tell the location of all parts of the computer sewing machine.

By changing the stitching pattern accurately before and after changing the stitching pattern when adjusting the needle assembly, the computer can generate infinite shapes and lines.

A sewing machine needs only to load patterns or create patterns from memory, and almost everything else can be delivered to the computer.

The computer will remind the sewing operator to change the line or make other adjustments when necessary.

Obviously, this high-tech sewing machine is much more complex than the completely manual sewing machine 200 years ago, but they are all based on the same simple sewing system: the needle passes through the fabric to produce a coil and is caught by another thread.

Some creative ideas have changed the world forever. This creative method is one of them.
