Information
1. Introduction:   
 
EPE pearl cotton foaming machine is a special equipment used to produce EPE pearl cotton sheets. It melts the DPE resin and mixes it with other additives such as butane, talcum powder, anti-shrinking agent, etc., extrudes through an extrusion mechanism, and foams in the die head and die lip part, and finally passes through the wind ring and the shaping ring to cool and expand into Fixed-size pearl cotton sheet, the final product is taken up by a take-up roller.
 
2. Company introduction:
 
Chongqing Jiecheng Plastic Equipment Factory has long been committed to the research and production of sponge series products. The main product types and characteristics are polyester sponge, polyether sponge, closed-cell sponge, open-cell sponge, packaging shockproof sponge, and super soft sponge. Hard sponges, high-density sponges, sound-absorbing and heat-insulating sponges, composite adhesive sponges, conductive antistatic sponges, color and color sponges, shape deep-processing sponges, rubber-plastic foaming sponges, and mass production mechanized continuous assembly line hair Foam sponge materials, high-quality sponge products and products, provide high-quality flat foam, round foam, net foam, high elasticity, high load-bearing and other high-quality sponges and rubber-plastic foam products.
 
3. Analysis of the advantages of using easy-drive frequency converter on foaming machine   
 
1. The frequency conversion technology can effectively control the speed of the motor, and has the advantages of wide speed adjustment range, high speed adjustment accuracy, and fast dynamic response;   
 
●Adjustable operating speed: The frequency conversion technology adjusts the output voltage proportionally while adjusting the output frequency, thereby changing the motor speed and realizing stepless speed regulation;
 
●Acceleration controllable: variable frequency speed regulation can be started at zero speed, and correspondingly accelerated according to demand, acceleration curve can be selected according to design requirements;
 
●Using microcomputer control technology to control the frequency converter, it can realize a variety of transmission speed regulation functions: various frequency setting and execution, starting, operation mode selection, torque control setting and operation, acceleration and deceleration design and operation, braking Mode setting and execution make the frequency conversion technology more intelligent, and the application field is broader.
 
2. The protection function of frequency conversion technology is relatively complete, which can effectively control the protection and monitoring of the motor, the life of mechanical parts, and the current and voltage fluctuations of the power grid;
 
In terms of the loss of mechanical parts, the selection of the motor stop mode (deceleration stop, free stop, deceleration stop and DC braking, etc.) of the frequency conversion speed regulation can reduce the impact of the motor and its linked mechanical parts; dynamically adjust the torque limit to avoid mechanical Does not reduce damage.
 
3. Frequency conversion technology has significant advantages in energy saving and maintenance.
 
First, the frequency conversion technology realizes soft start with low starting current. The power of the motor is proportional to the product of current and voltage, and the power consumed by the motor directly started by the industrial frequency will be much higher than the power required for variable frequency start;
 
Second, the variable frequency speed control motor operates at a low slip rate, which reduces the loss of the motor itself and has high working efficiency. At the same time, as application requirements change, the frequency conversion speed regulation system can quickly and dynamically adjust the speed to minimize power consumption.
 
4.Easy drive CV3100 frequency converter features
 
1. V/F control mode (one drive multiple) A. Advanced vector control algorithm, optimized SVPWM output, low output harmonics and small motor temperature rise. B. Realize optimal energy-saving operation through motor parameter detection.
 
2. Open-loop vector control (SVC) mode A. Using TI high-speed motor control dedicated DSP processor, it can complete complex vector calculations at high speed and accurately, and achieve complete decoupling of the motor. B. Using advanced motor model algorithm, 0.5Hz can output 150% rated torque, stable speed accuracy 0.5%, speed regulation range 1:100.
 
3. Standard RS485 interface, support MODBUS communication protocol, and can communicate with host computer such as touch screen, PLC, etc.
 
4. Complete protection measures can protect nearly 20 kinds of faults such as overvoltage, undervoltage, input phase loss, output phase loss, overload, overheating, overcurrent, external terminal failure, communication failure, current detection error, motor tuning failure, etc. , Higher reliability.
