[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figure 1-5 The shown is a winding device for CPET coated composite paper, including a mounting frame 1, a controller 2 mounted on the outer wall of the mounting frame 1, a winding roller 3 rotatably connected to the opposite inner wall of the mounting frame 1, one end of the winding roller 3 penetrating the mounting frame 1 and extending to the outer wall of the mounting frame 1 where a drive motor 4 is mounted; a cooling assembly 5 is mounted on the inner wall of the mounting frame 1, and a stretching assembly 6 is mounted on the inner wall of the mounting frame 1.

[0017] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 4The cooling assembly 5 includes a hollow cooling roller 501, which is rotatably connected to the opposing inner walls of the mounting frame 1. An arc-shaped pressure plate 502 is installed directly above the hollow cooling roller 501 and on the opposing inner walls of the mounting frame 1, with a gap between the arc-shaped pressure plate 502 and the hollow cooling roller 501. Two sets of rotating bases 503 are installed on the opposing outer walls of the hollow cooling roller 501, respectively located on the opposing outer walls of the mounting frame 1. The connection between 03 and the cooling hollow roller 501 is a rotatable connection. A connecting pipe 504 is installed at one end of the rotating base 503. A circulating water pump 505 is installed on the outer wall of the mounting frame 1. The inlet of the circulating water pump 505 is connected to the connecting pipe 504. A chiller 506 is installed on one side of the circulating water pump 505 and on the outer wall of the mounting frame 1. The inlet of the chiller 506 is connected to the circulating water pump 505 through a conduit, and the outlet of the chiller 506 is connected to the rotating base 503 on the other side through a conduit.

[0018] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 5 The tension assembly 6 includes a tension sensor 601, a rotating rod 602, and a rotating rod 603. The tension sensor 601 is disposed on the opposing inner walls of the mounting frame 1. Two sets of rotating rods 602 are disposed on the opposing inner walls of the mounting frame 1, and an electrically controlled cylinder 604 is rotatably connected to the outer wall of the rotating rod 602. Two sets of rotating rods 603 are disposed on the opposing inner walls of the mounting frame 1, and a limit plate 605 is rotatably connected to the outer wall of the rotating rod 603. The outer wall of the limit plate 605 passes through... A rotating shaft 606 is connected to an electrically controlled cylinder 604, wherein the rotating shaft 606 and the electrically controlled cylinder 604 are connected by a rotatable connection. A limiting groove 607 is provided on the outer wall of the limiting plate 605. A limiting slider 608 is slidably connected on the inner wall of the limiting groove 607. A tension roller 609 is installed on the outer wall of the limiting slider 608. A push-pull cylinder 610 is installed directly below the limiting slider 608 and on the outer wall of the limiting plate 605, and one end of the push-pull cylinder 610 is connected to the limiting slider 608.

[0019] Based on the above structural features and connection relationships, one end of the CPET coated composite paper is sequentially passed through the stretching roller 609, the tension sensor 601, and the cooling hollow roller 501, and one end of the CPET coated composite paper is wrapped around the outer wall of the winding roller 3 for fixation. Then, the switch of the controller 2 is turned on, which will cause the controller 2 to control the drive motor 4 to run, thereby causing the drive shaft of the drive motor 4 to drive the winding roller 3 to rotate, so that the winding roller 3 can wind up the CPET coated composite paper. The controller 2 is electrically connected to the drive motor 4, circulating water pump 505, chiller 506, tension sensor 601, electric cylinder 604, and push-pull cylinder 610 via wires, thereby energizing the device and enabling the controller 2 to control the operation of the drive motor 4, circulating water pump 505, chiller 506, tension sensor 601, electric cylinder 604, and push-pull cylinder 610.

[0020] This solution is used for the winding equipment of CPET coated composite paper. When working, one end of the CPET coated composite paper is passed through the tension roller 609, the tension sensor 601 and the cooling hollow roller 501 in sequence, and the other end of the CPET coated composite paper is wrapped around the outer wall of the winding roller 3 for fixation. Then, the switch of the controller 2 is turned on, which will cause the controller 2 to control the drive motor 4 to run, and then the drive shaft of the drive motor 4 will drive the winding roller 3 to rotate, so that the winding roller 3 can wind up the CPET coated composite paper.

[0021] By turning on the switch of controller 2, controller 2 will control the circulating water pump 505 to operate, causing the circulating water pump 505 to draw coolant from the inner cavity of the cooling hollow drum 501 through the connecting pipe 504. The circulating water pump 505 then circulates the coolant, which is then discharged through a conduit into the inner cavity of the chiller 506. Controller 2 then controls the chiller 506 to operate and cool the coolant. The chiller 506 then discharges the coolant through a conduit into the other side of the vortex... The base 503 is rotated so that the cooled liquid is discharged into the cooling hollow roller 501. When the CPET coated composite paper passes through the gap between the arc-shaped pressure plate 502 and the cooling hollow roller 501, the surface of the cooling hollow roller 501 will cool the CPET coated composite paper. This solves the problem that in existing composite paper winding equipment, the CPET coated composite paper is prone to shrinkage or deformation when the temperature rises due to friction during winding. If the process temperature is not properly controlled, it may cause the composite paper to curl, wrinkle or delaminate.

[0022] By setting parameters in controller 2, when the tension sensor 601 detects the tension of the CPET coated composite paper, the tension sensor 601 generates an electrical signal that is transmitted to controller 2 via wires. When the set parameters are reached, controller 2 controls the electric cylinder 604 to operate, causing one end of the electric cylinder 604 to pull the limiting plate 605 via the rotating shaft 606. This causes the limiting plate 605 to rotate on the outer wall of the rotating rod 603, thereby causing one end of the limiting plate 605 to drive the stretching roller 609 to... The CPET coated composite paper is subjected to lateral tension adjustment. At the same time, the controller 2 controls the push-pull cylinder 610 to operate, so that one end of the push-pull cylinder 610 pulls the limit slider 608 to move. This causes the limit slider 608 to move on the inner wall of the limit groove 607, which in turn drives the stretching roller 609 to adjust the longitudinal tension of the CPET coated composite paper. This solves the problem that uneven winding tension during winding of the winding equipment can cause material stretching deformation, wrinkles, or paper breaks.
