A new type of rotary tower dual station automatic winding machine for LCP liquid crystal film material. It is a specialized rewinding machine for LCP material blown film process. It can also be used for casting production lines. Due to the unique properties of LCP material. The linear speed is between 10-40 meters per minute. Conventional rewinding machines cannot meet the requirements. Therefore, developing a multifunctional new type of rewinder can fill the gap in the domestic market. Facing the current situation of 5G communication development. LCP thin film material is internationally recognized as a material. But the production lines for LCP films are monopolized by South Korea and Japan. It is far from enough to meet the subsequent market demand. Through continuous experimentation and efforts domestically. At present, it has been successfully manufactured and put into market use.
The winding machine has been used. (turret center+friction+clearance) coiling mode. Torque compensation. Conical tension control. It can maintain high torque at low speeds. It can also maintain torque at high speeds. The processing temperature of LCP film is above 300 degrees. After cooling and forming. Enter the winding area. If the roll is too tight. Orientation stretching will occur. Minor wrinkles appear. Affects the lamination with copper foil. If the winding is too loose, directional dielectric strength will occur.
The advantages of this winding machine are:
1. The turret type dual station can quickly switch between forward and reverse directions, and automatically change the A-axis and B-axis without stopping the machine. Automatic cutting. Reduce waste. Improve work efficiency.
2. Two pneumatic shafts are driven by servo motors for central winding. Efficient and energy-saving. The torque is stable. Replace torque motors and vector three-phase asynchronous motors.
3. Add frictional structures. Using an active rubber roller. Rotate in the same direction as the inflation axis tightly wrapped around the center. Eliminate surface marks on materials. Plays an auxiliary friction role. Avoid thick materials slipping and deviating. Thin material surface folds.
4. Add a gap control device. Measure the roll diameter of materials using ultrasonic sensors. Control the servo motor to drive the rack. Install a friction device on a straight track. Move the position according to the size of the material roll. Control the contact gap between the friction roller and the material. Meet the performance and thickness requirements of different materials for coiling. During automatic cutting or shutdown. Automatically return to the origin position. Pull apart and center the position of the A-axis and axis.
5. The bottom bracket of the winding is equipped with a servo edge correction device. Control the edge position of material winding. Correct the material during low-speed and high-speed winding. And the material deviation caused by coil replacement.
6. Automatic cutting of parts. Adopting non stretching reverse cutting method. The knife holder flips up from below. There are rubber rollers in front and behind the knife holder. Adhesive material. Beneficial for flying knife cutting. At the same time, there is almost no stretching of the material. So as not to affect the cutting process. Material looseness and tension fluctuations. After cutting is completed, the knife holder automatically returns to the bottom. It retains the spatial location while freeing up space for manual membrane penetration and equipment maintenance. Easy to disassemble and maintain.
7. Add a traction device. Can be used independently offline. Easy to be used in conjunction with other production lines.
8. Add slitting function. Cut materials online. Recycling and coiling of waste edges.
9. Adopt swing arm tension. Can produce PE and CPP. EVA。 PET。 Material Science.
10. The electrical control is installed on the outer casing. Easy to operate. The integrated structure is convenient for installation and transportation.
