[0022] When the staff uses external force to make the sleeve 4 slide upward and slide on the surface of the rotating rod 3, the L-shaped ring 7 will squeeze the spring 6, and the squeezing force on the top of the ball 9 will disappear, so that the ball 9 originally stuck in the inner side of the trapezoidal groove annular block 11 will return to its original position due to the elastic recovery effect of the flexible film fixedly installed on the inner side of the circular groove 8, so that it can be replaced smoothly. When installation is required, the external force of the sleeve 4 disappears, and the elastic recovery effect of the spring 6 pushes the L-shaped ring 7 to squeeze the ball 9 into the inner side of the trapezoidal groove annular block 11 to achieve fixation.
[0023] When the sleeve 4 slides upward on the surface of the rotating rod 3, the L-shaped ring 7 will squeeze the spring 6, and the squeezing force on the top of the ball 9 will disappear, so that the ball 9 originally stuck in the inner side of the trapezoidal groove annular block 11 will return to its original position due to the elastic recovery effect of the flexible film fixedly installed on the inner side of the circular groove 8, so that it can be replaced smoothly. When installation is required, the external force of the sleeve 4 disappears and the elastic recovery effect of the spring 6 pushes the L-shaped ring 7 to squeeze the ball 9 into the inner side of the trapezoidal groove annular block 11. Compared with the traditional device, the present device greatly reduces the equipment downtime and enables the production process to be carried out more continuously, which reduces the complexity of the workers' operation and reduces the requirements for the workers' skill level. Workers do not need to spend a lot of time repairing or replacing complex connecting parts, reducing the overall manual maintenance workload.
[0024] Among them, a bracket 20 is fixedly installed on the left side of the top of the base plate 1, and a screw rod 21 is rotatably installed inside the bracket 20 and the screw rod 21 extends out of the bracket 20. A moving block 22 is threadedly sleeved on the outer surface of the screw rod 21 and the two ends of the screw rod 21 pass through the inside of the moving block 22. The screw rod 21 extends out of the outer surface of the top of the bracket 20 and a rotating block 23 is fixedly installed. A supporting template 24 is fixedly installed on the back of the moving block 22. A triangular groove 25 is provided on the outer surface of the supporting template 24, and a circular protrusion 26 is fixedly installed on the outer surface of the supporting template 24, and the circular protrusion 26 is in an array shape.
[0025] When the staff rotates the rotating block 23, the screw rod 21 will start to rotate. When the screw rod 21 starts to rotate, the moving block 22 will start to move up and down. When the moving block 22 starts to move up and down, it will drive the supporting template 24 fixed thereto to move up and down synchronously. When the supporting template 24 moves up and down, the triangular groove 25 on the outer surface of the supporting template 24 will generate suction. When the supporting template 24 moves up and down, the circular protrusion 26 will move up and down, providing multi-point support for the polyurethane foam.
[0026] By rotating the rotating block 23, the screw rod 21 will start to rotate. When the screw rod 21 starts to rotate, the moving block 22 will start to move up and down. When the moving block 22 starts to move up and down, it will drive the supporting template 24 fixed thereto to move up and down synchronously. When the supporting template 24 moves up and down, the triangular groove 25 opened on the outer surface of the supporting template 24 will generate suction. When the supporting template 24 moves up and down, the circular protrusion 26 will move up and down. Compared with the traditional device, this device can effectively reduce the dislocation during the winding process of the polyurethane foam, reduce the wear rate of the polyurethane foam, improve the yield of the polyurethane foam, reduce the cost caused by dislocation, reduce the time for repairing equipment, and speed up work efficiency.
[0027] Among them, a support plate 27 is fixedly installed on the rear end of the top outer surface of the right side of the base plate 1, a connecting rod 2 17 is rotatably installed on the front of the support plate 27, and a groove is provided on the outer surface of the connecting rod 2 17, a polyurethane foam reel 15 is fixedly installed on the inner side of the connecting rod 12, a connecting protrusion 16 is fixedly installed on the inner side of the polyurethane foam reel 15, and the connecting protrusion 16 is matched with the groove provided on the outer surface of the connecting rod 2 17, and a power mechanism is fixedly installed on the back side of the support plate 27.
[0028] The connecting protrusion 16 can smoothly fit into the groove opened on the outer surface of the connecting rod 2 17, thereby facilitating the power transmission of the power mechanism. Since the connecting protrusion 16 does not completely fit into the groove opened on the outer surface of the connecting rod 2 17, it can be completely fit into during disassembly, so that the winding device can be smoothly disassembled to avoid getting stuck.
[0029] Among them, a cross protrusion 13 is fixedly installed on the inner side of the connecting rod 12, and a cross groove block 14 is opened on the outer surface of the top of the rotating rod 3, and the cross protrusion 13 and the cross groove block 14 are exactly matched.

[0031] Among them, a guide rod 10 is rotatably installed on the back side of the support plate 1 2, and the guide rod 10 extends to the front side of the support plate 2 27 and is rotatably connected thereto.
[0032] By extending the guide rod 10 to the front of the support plate 2 27 and rotatingly connecting with it, the accuracy of the foam rolling position is ensured, and the foam can be smoothly guided along the guide rod 10 to the polyurethane foam winding wheel 15, making the threading process simpler and faster.
[0033] Among them, the power mechanism includes a support plate 27 with a bracket 18 fixedly installed on the back, a motor 19 fixedly installed on the bottom of the bracket 18, and the output shaft of the motor 19 extends to the inside of the support plate 27 and is fixedly connected to the connecting rod 2 17.
[0034] By starting the motor 19, the output shaft of the motor 19 will drive the connecting rod 2 17 to rotate. When the connecting rod 2 17 rotates, it will drive the connecting protrusion 16 to rotate. When the connecting protrusion 16 rotates, it will drive the polyurethane foam reel 15 to start rotating, which can greatly improve efficiency.
[0035] A base 28 is fixedly mounted on the bottom of the base plate 1 , and the base 28 is present around the bottom of the base plate 1 .
[0036] By presenting the base 28 around the bottom of the base plate 1, the stability of the winding device for the production of polyurethane foam can be effectively guaranteed, and the winding process can be effectively guaranteed to remain stable.
[0037] The working principle and use process of this utility model:
[0038] When the staff uses external force to make the sleeve 4 slide upward and slide on the surface of the rotating rod 3, the L-shaped ring 7 will squeeze the spring 6, and the squeezing force on the top of the ball 9 will disappear, so that the ball 9 originally stuck in the inner side of the trapezoidal groove annular block 11 will return to its original position due to the elastic recovery effect of the flexible film fixedly installed on the inner side of the circular groove 8, so that it can be replaced smoothly. When installation is required, the external force of the sleeve 4 disappears, and the elastic recovery effect of the spring 6 pushes the L-shaped ring 7 to squeeze the ball 9 into the inner side of the trapezoidal groove annular block 11 to achieve fixation.
[0039] When the staff rotates the rotating block 23, the screw rod 21 will start to rotate. When the screw rod 21 starts to rotate, the moving block 22 will start to move up and down. When the moving block 22 starts to move up and down, it will drive the supporting template 24 fixed thereto to move up and down synchronously. When the supporting template 24 moves up and down, the triangular groove 25 on the outer surface of the supporting template 24 will generate suction. When the supporting template 24 moves up and down, the circular protrusion 26 will move up and down, providing multi-point support for the polyurethane foam.
