Cutting Method And Static Shearing Mechanism Of Embroidery Machine

< p > < < a > href= > //www.sjfzxm.com/news/ > embroidery machine > /a > the automation level is constantly improving. Higher requirements for embroidery quality and efficiency are put forward. Our company has launched the latest two kinds of new stepper motor dynamic shear line control system and step closed loop color changing system.

Its control performance and efficiency surpass traditional cutting and color changing methods.

It can better satisfy the practical, stable and reliable performance requirements of the embroidery thread cutting and color changing function. It improves the embroidery quality and production efficiency of the embroidery machine, and ensures the convenience of installation, debugging and maintenance of the embroidery machine. It will become a popular embroidery machine model in the future.

< p > computerized embroidery machine's traditional a href= "//www.sjfzxm.com/news/index_c.asp" > shear line method < /a > has many kinds, including electromagnet shear line mode, AC motor static shearing mode, and 42 step motor instead of electromagnet shear line mode.

In order to further enhance the effect and efficiency of wire cutting, a new dynamic shear line control system of stepper motor is newly introduced.

Cutting and color changing are the basic functions of computerized embroidery machines.

The thread cutting and color changing system is an important subsystem in the computer embroidery machine control system. Whether it has the function of automatic thread cutting and color changing is an important criterion to distinguish the degree of automation of computerized embroidery machine.

The quality of embroidery will directly affect the quality of embroidery and the production efficiency of embroidery machines.

Whether the color changing position is accurate will directly affect the rate of embroidery disconnection.

After years of research and development, the embroidery machinery control system supports all the common cutting and color changing mechanisms, which can meet users' functional requirements.

< p > 1. electromagnet shear line mode < /p >

< p > the way of cutting the electromagnet is that when the spindle of the computerized embroidery machine is rotated to the last lap, the main shaft drives the scissors to complete the shearing action by shearing the cam, which has the advantages of low cost, large noise, and the stability of the shear line is influenced by the spindle speed, and the length of the shearing line can be adjusted.

< p > 2. electromagnet shear line mechanism < /p >

< p > 3.42 stepper motor instead of electromagnet shear line mode < /p >

< p > stepping motor instead of electromagnet shear line mode is similar to the way of electromagnet shearing. It uses 42 stepper motor instead of shear wire electromagnet to connect main shaft to scissors connecting rod, and drives the scissors connecting rod through the main shaft to complete the shearing action. This cutting way has low noise, low cost, adjustable length of shear line, and the effect of shear line stability and shear effect is influenced by spindle speed.

< p > 4.42 stepper motor instead of electromagnet shear line < /p >

< p > 5. static cutting mode of AC motor < /p >

< p > static shearing wire is also called motor shears. It means that the main shaft stops first when the thread is cut. The single phase asynchronous motor drives the scissors connecting rod to complete the shearing action under the condition of the spindle of the embroidery machine at a static state. The cutting way is simple in mechanical structure, low in noise, and the effect of shearing is not affected by the spindle speed, the cost is low, and the length of the shearing line is determined by the mechanical size.

< p > 1. new progressive closed loop shear line < /p >

< p > the stepper motor shears are driven directly by stepper motor to the scissors connecting rod, and the cutting action is completed with the angle of the spindle when cutting.

< /p >

< p > 1. is highly controllable. It can adjust the action angle and action curve of the scissors through the computer, and simulate the operation of the cutting cam, such as cutting and closing the knife.

< p > 3. stepper shear motor direct drive scissors, away from the spindle, shear line effect is not affected by spindle speed.

< p > 4. motor shears, low shearing noise.

< /p >

< p > 5. electric control system controls motor movement curve instead of cam curve, and the motion curve can be flexibly adjusted with the electric control parameters to find the best scissors cutter and cutter curve, so that the customer can adjust the trimming effect.

< p > 6. < a href= "//www.sjfzxm.com" > Machinery < /a > the structure is greatly simplified, compared with the traditional way of cutting, it is more convenient to maintain and debug.

< p > new step closed loop color changing system < /p >

< p > for a long time, the color changing mechanism of the embroidery machine adopts single-phase AC motor driven screw type mechanism, which is restricted by the mechanism in the color changing speed, the color changing accuracy and the number of color changing pins, and can not be further improved.

The newly developed stepper closed loop color changing system, which is in line with the new screw color changing mechanism, surpasses the traditional thread screw system completely. The stepping motor can rotate more than 1200 turns, and can easily realize the high speed color changing of 1~9 pin changing time less than 2 seconds. The high-precision electric positioner is used to achieve higher positioning accuracy, and the color changing position of each needle position can be fine tuned by the operation head.

The new screw thread mechanism is lighter in load than the previous screw structure, and there is no pause position in the process of color changing. The color changing process is more continuous and the color changing speed is faster.

It is believed that the introduction of the new step closed loop color changing system will completely subvert the application experience of customers for the color changing system of embroidery machines.
