How To Choose The Control System Of Computerized Embroidery Machine

With the continuous growth of computer embroidery machine market in China and even the whole world, the domestic computer embroidery machine industry is developing rapidly.

According to relevant forecasts, the demand for China's computerized embroidery machine market is expected to increase from 3 to 60 thousand in 2004 to 70 thousand in 2010. Meanwhile, the demand for computerized embroidery machines worldwide will increase from 60 thousand to 60 thousand in 2010 and 100 thousand yuan per year.

Driven by strong demand, it is the core component of computerized embroidery machine.

Computer embroidery machine control system has entered a rapid development cycle. Many brands of related products have appeared at home and abroad, and there are many products that the computer embroidery machine manufacturers can choose on the market.

However, because the computerized embroidery machine is a kind of electromechanical integration product, which is different from the pure mechanical products in the past, the computer embroidery machine manufacturers should consider more problems when choosing the control system for product design and product matching. Besides the consideration of the quality of the control system, it is also necessary to consider the compatibility of the control system with other components, electromechanical coordination and other aspects.

The following is a summary of some common basic questions for reference.

Electromechanical coordination

Because the computer control system is designed and applied according to some specific computerized embroidery machines, the computerized embroidery electrical control system is difficult to adapt to all the structural control requirements of the whole machine.

When ordering, users must specify requirements.

Peripheral matching

The computer embroidery machine is a computer system that controls the movement of embroidery machinery by controlling the peripheral actuator such as motor and electromagnet.

Therefore, the matching relationship between mechanical and electrical directly affects the performance and function index of the computerized embroidery machine.

1, embroidery frame and driving stepper motor

The weight and inertia of the embroidery frame should be matched with the output torque and the torque frequency characteristics of the stepping motor.

The various indicators of the motor are far greater than the demand of the embroidered frame driven by it, which will cause unnecessary waste and unnecessary increase.

Conversely, if the driving force of the stepping motor is not enough, it will cause some problems such as pattern walk, motor overheating, noise increase and life expectancy reduction.

Therefore, when choosing a stepper motor driving the embroidery frame, the user should choose the appropriate motor according to the size, weight and pmission mechanism of the embroidery frame.

2. Spindle mechanical system and spindle drive motor

The pmission load of the spindle mechanical system should match the output power of the spindle drive motor.

The output power of the spindle motor is smaller than that of the spindle drive, which will directly affect the parking accuracy, operation stability and embroidery effect of the whole machine.

Therefore, when selecting the spindle motor type (such as servo, slip, variable frequency motor), motor output power and motor inertia, users should fully analyze the pmission characteristics of the spindle system, and estimate the pmission inertia and maximum load torque of the spindle pmission system, and then choose the right spindle motor when there is a certain margin.

3. Color changing motor and color changing mechanism

The type and parameter of the color changing motor should be matched with the type and load of the color changing mechanism.

For AC motor commutation, the AC motor with different power and different output torque (different pmission ratio) should be selected according to the number of the whole machine and the number of needle boxes.

For the 1-2 types of stepper color changing machines, the 42 hybrid stepping motor is usually adopted because of the installation position. This requires high mechanical pmission and can not be overloaded, otherwise it will not work normally.

Purchasing peripheral parameters

All kinds of electrical components are described by various parameters.

Therefore, the type and parameters of the selected products should be carefully matched with the mechanical design when selecting the type.

Otherwise, it will not be able to meet the requirements.

For example: BYGll0 is also a stepper motor, its working current, static torque, frequency characteristics may be different.

The servo motor system of the same power has many differences in motor drive inertia and shape volume.

The same size of the electromagnet, its inductance, working voltage, working current may also be different.

Quality aspects of peripherals

The quality of the selection of electrical products directly determines whether the computerized embroidery machine can operate in a long-term and stable manner.

Facts have proved that the poor quality of the peripheral electrical products makes the computer embroidery machine not normally used.

Among them are:

1. Stepper motor: low machining accuracy, poor material, small output torque, large noise, causing loss of step, even locking in operation and losing use function.

2, the electromagnet: unreasonable assembly, low machining accuracy, poor insulation and serious leakage, which directly cause the burn of the circuit board of the electronic control system and paralyze the embroidery machine.

3, flat signal cable: quality is unreasonable, often open circuit, short circuit phenomenon, so that embroidery machine is difficult to work steadily.

Therefore, it is recommended that users purchase excellent quality peripheral electrical products to eliminate all kinds of hidden troubles.
