Description

Technical Field

[0001] The utility model relates to the technical field of waste edge winding equipment, in particular to a synchronous winding device for multiple waste edges. Background Art

[0002] During the production process of the film, especially when applying glue or undergoing other processing, glue-free areas or other irregular edges may form at both ends. These glue-free areas or irregular edges not only affect the aesthetics of the film, but may also cause equipment contamination or unstable product performance during use. By trimming, these glue-free areas or irregular edges can be removed, making the appearance of the film neater and more beautiful. At the same time, trimming helps to improve the performance of the film.

[0003] When trimming, both ends of the film should be trimmed at the same time, and the waste edges at both ends need to be rolled up at the same time. The traditional method is to use two independent winding devices to collect the waste edges, but this method has some obvious disadvantages, such as occupying a large space and requiring two people to operate the roll change operation at the same time.

[0004] Therefore, it is urgent to improve the waste edge winding device to solve the problem that two or even more independent winding devices occupy a large space and the roll changing operation requires the cooperation of multiple people, so as to improve the film trimming effect and the efficiency of waste edge collection. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a synchronous winding device for multiple waste edges.

[0006] The utility model adopts the following technical solutions:

[0007] A multi-waste edge synchronous winding device comprises a base, a frame and a control cabinet, wherein a motor is arranged in the control cabinet, and a floating roller, a fixed guide roller, a sliding track, a rubber pressing roller, a winding shaft and a winding arm sliding track are arranged on the frame; the motor drives the rubber pressing roller to rotate; a movable guide roller is installed on the sliding track; two winding arms are arranged on the winding arm sliding track, and the other ends of the two winding arms are respectively connected to the two ends of the winding shaft, and a winding arm moving cylinder is arranged on the winding arm close to the control cabinet, and the winding arm moving cylinder can slide left and right along the winding arm sliding track to clamp the winding tube core on the winding shaft, and remove it when the winding tube core needs to be removed; a winding arm swinging cylinder is arranged on the winding arm far away from the control cabinet to control the winding shaft to swing back and forth as the winding roll diameter changes, so as to keep the pressure with the rubber pressing roller constant. A winding tube core is sleeved on the winding shaft, and the rubber pressing roller presses against the winding tube core and the surface of the waste edge roll; the multi-channel waste edges are rolled on the winding tube core via floating rollers, fixed guide rollers and movable guide rollers.

[0008] Preferably, a displacement sensor is fixedly mounted on the frame, a servo motor is provided on the slide track, and the output end of the servo motor is connected to the movable guide rail; the slide track, the movable guide roller, the servo motor and the displacement sensor constitute a displacement control unit. The scrap edge is guided to the movable guide roller through the fixed guide roller, and the servo motor enables the movable guide roller to move left and right on the slide track with the scrap edge under the control of the displacement sensor, so that the scrap edge is evenly collected on the winding tube core.

[0009] Preferably, the floating roller is located on a floating roller bracket, and a potentiometer and a low-friction cylinder are also provided on the floating roller bracket. The floating roller bracket, the floating roller, the potentiometer, and the low-friction cylinder constitute a tension control unit. The floating roller introduces the scrap edge into the winding device. When the scrap edge tension fluctuates, the floating roller bracket will swing accordingly with the floating roller. The potentiometer indirectly detects the tension change and adjusts the winding speed through the PID controller to keep the film tension constant. At the same time, the film tension can be directly adjusted by changing the pressure of the low-friction cylinder, and the tension size is independent of the film roll diameter; and it can be adjusted according to specific conditions, with an adjustment range of 1-4kg.

[0010] PID stands for Proportional Integral Differential. It is a device used for different process variables such as pressure, flow, temperature, speed, etc. in industrial applications. When the potentiometer detects a change, the control system receives feedback to determine how much the winding speed needs to be adjusted to the target value. PID accurately adjusts the speed to the target value quickly through proportional, integral, and differential control. Proportional control-adjusts the speed to the target value quickly according to a certain ratio, integral control-eliminates steady-state errors during the adjustment process, and differential control-reduces oscillations during speed adjustment.

[0011] Preferably, baffles are respectively provided at both ends of the floating roller, the fixed guide roller and the movable guide roller; the baffles are provided to prevent the scrap edges from sliding out, thereby bringing together the scrap edges of multiple channels that need to be collected.

[0012] Preferably, a 3-inch winding tube core is sleeved on the winding shaft, and winding baffles are provided at both ends of the winding shaft to effectively prevent the waste edges from slipping out of the tube core and ensure stable tension; through the precise control of the winding arm swing cylinder, the winding shaft can move flexibly as the roll diameter changes and maintain a constant pressure between the rubber pressing roller, thereby facilitating the collection of multiple waste edges on one winding tube core at the same time.

[0013] Preferably, the rubber pressing roller is a steel rod wrapped with rubber and is non-sticky, and the rubber pressing roller drives the winding shaft to rotate.

[0014] Preferably, an operation panel is provided on the control cabinet.

[0015] Preferably, the operation panel can set the pressure between the reel and the rubber pressing roller, and the tension of the waste edge.

[0016] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0017] 1. The multi-waste edge synchronous winding device in the utility model can simultaneously wind up the waste edges of multiple channels, avoiding the use of multiple independent winding devices, saving the space occupied by the winding device, and making the roll changing operation more convenient.

[0018] 2. The rubber pressing roller in the utility model presses against the surface of the winding tube core and its waste edge roll, driving the winding shaft to rotate. Through the precise control of the winding arm swing cylinder, the winding shaft can move flexibly as the roll diameter changes and maintain a constant pressure between the rubber pressing roller, thereby facilitating the collection of multiple waste edges on one tube core at the same time.

[0019] 3. By installing rewinding baffles at both ends of the rewinding shaft, the rewinding shaft can accommodate more waste edges, effectively reducing the need for frequent reel changes and improving work efficiency.

[0020] 4. In the utility model, when collecting waste edges, a movable guide roller is used to evenly collect the waste edges on the entire winding tube core, thereby improving the utilization rate of the tube core, reducing the frequency of tube core replacement, and improving work efficiency; avoiding the tension fluctuation caused by the waste edges sliding off as the roll diameter increases when collecting waste edges at a fixed position, thereby ensuring neat trimming and improving the film trimming effect and waste edge collection efficiency.
