Electromechanical cooperation

    Since the computer control system is designed and applied according to some specific computer embroidery machine models, the computerized embroidery electronic control system is difficult to adapt to all the changes in the mechanical structure control requirements of the whole machine. The user must specify the order when ordering.

Peripheral matching

    The computer embroidery machine is a computer system that drives the embroidery machine movement by controlling the action of peripheral actuators (such as motors, electromagnets, etc.). Therefore, the mechanical and electrical matching relationship directly affects the performance and functional indicators of the computerized embroidery machine.

    1, the frame and the drive stepper motor

    The weight and inertia of the frame should match the output torque and torque frequency characteristics of the stepper motor. The various indicators of the motor are much larger than the requirements of the frame that it drives, which will result in unnecessary waste and volume increase. Conversely, if the driving force of the stepping motor is insufficient, it will cause problems such as pattern movement, motor overheating, noise increase, and reduced life. Therefore, when selecting the stepping motor that drives the frame, the user should select the appropriate motor according to the size, weight and characteristics of the transmission mechanism.

    2. Spindle mechanical system and spindle drive motor

    The drive load of the spindle mechanical system is matched to the output power of the spindle drive motor. If the spindle motor output power is less than the spindle drive load, it will directly affect the parking accuracy, running stability and embroidery effect of the whole machine. Therefore, when selecting the spindle motor type (such as servo, slip, variable frequency motor) and the output power of the motor and the drive inertia of the motor, the user needs to fully analyze the transmission characteristics of the spindle system, and estimate the transmission inertia of the spindle drive system, the maximum load. Torque, and then leave a certain margin, select the appropriate spindle motor.

    3. Color changing motor and color changing mechanism

    The type and parameters of the color change motor should match the type and load of the color change mechanism (the motor concentrated hook line also falls into this category). For the AC motor color change, the AC motor with different power and different output torque (different gear ratio) should be selected according to the number of the whole machine and the number of needles in the needle bar box. For the general model with 1-2 head color change, it is generally limited by the installation position, 42 hybrid stepping motor is used, which puts high requirements on the mechanical transmission, the load can not be too heavy, otherwise it will Can not work normally.
