[0002] Hydrolysis-resistant polyester film is produced by adding hydrolysis-resistant agents and other auxiliary agents during the production process of traditional polyester film, so that the final polyester film has excellent hydrolysis resistance. Because of its excellent hydrolysis resistance, it is often used in hot and humid working environments.

[0003] During the production process, the film is still transported through the winding roller. During this process, the film needs to be stretched. During the transportation process, the stretched film is prone to wrinkles during the winding process, and the wrinkles will affect the transportation and even the subsequent production. For this purpose, an anti-wrinkle device is set up. Utility Model Content

DETAILED DESCRIPTION

[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] Please refer to Figure 1-3 The utility model discloses an anti-wrinkle device for producing hydrolysis-resistant polyester film, comprising a column 1, two columns 1 are provided, the side walls of the two columns 1 opposite to each other and close to the top are rotatably connected with a rotating roller 2, a vertical plate 3 is fixedly connected to the middle of the top side wall of the column 1, a screed plate 4 is provided above the rotating roller 2, the screed plate 4 is an arc-shaped structure corresponding to the rotating roller 2, the inner wall of the screed plate 4 is in contact with the outer wall of the rotating roller 2, a lifting groove 6 is provided in the middle of the opposite side walls of the two vertical plates 3, a follower block is fixedly connected to the end of the screed plate 4 opposite to the lifting groove 6, and the follower block is slidably connected in the lifting groove 6;

[0015] A spring 7 is fixedly connected in the middle of the top side wall in the lifting groove 6, and the spring 7 is fixedly connected to the top side wall of the follower block through the bottom end. A pressing plate 5 is fixedly connected to the top side wall of the screed plate 4. A movable groove 8 is opened on the side wall of the vertical plate 3 close to the lifting groove 6. A linkage block is slidably connected in the movable groove 8, and the linkage block is fixedly connected to the side walls of the pressing plate 5 at both ends close to the vertical plate 3.

[0016] The technical effect of this solution is that the polyester film is pre-wound on the rotating roller 2, and as the driver drives the rotating roller 2 to rotate, the polyester film can be transported and wound on the rotating roller 2, and the bubbles between the wound polyester film can be squeezed out by the pressing of the smoothing plate 4 to avoid wrinkles caused by bubbles. At the same time, the pressing of the smoothing plate 4 can also smoothen the slight wrinkles that have already occurred, ensuring that the surface of the wound polyester film roll is relatively flat and smooth, avoiding the storage after winding or the processing of the next step being affected by wrinkles.

[0017] An extension column 9 is fixedly connected to the side wall of the column 1 near the top, and the side walls opposite to the two extension columns 9 are rotatably connected to auxiliary rollers 10. Two movable columns 11 are set up on the side of the extension column 9 away from the column 1, and the side walls opposite to the two movable columns 11 and located at the top edge are fixedly connected to a fixed plate 12, and a stretching splint 13 is set up below the fixed plate 12, and the side walls opposite to the fixed plate 12 and the stretching splint 13 are evenly rotatably connected to ball bearings 18. An adjustment groove 15 is opened inside each movable column 11 near the top, and a screw 16 is rotatably connected in the adjusting groove 15. The screw 16 is threadedly connected to a slider 17, and the slider 17 is fixedly connected to one end of the stretching splint 13. The top of the screw 16 passes through the side wall of the adjusting groove 15 and is fixedly connected to a knob 14.

[0018] The technical effect of this solution is to pass the two sides of the polyester film through the middle of the fixed plate 12 and the stretching clamp 13, and adjust the stretching clamp 13 to be close to the fixed plate 12 to clamp the polyester film, so as to position the two sides of the polyester film to prevent the polyester film from shrinking toward the middle and generating wrinkles. In order to ensure the normal transportation of the polyester film, a ball 18 is provided to rotate with the polyester film, and a non-slip rubber pad is provided on the surface to avoid wear on the polyester film.

[0019] Specifically, when the utility model is used, the polyester film is passed through the fixed plate 12 and the auxiliary roller 10 in sequence and finally wound on the rotating roller 2. As the rotating roller 2 rotates, the diameter of the polyester film roll will become larger and larger. In order to ensure smooth winding, a lifting groove 6 and a spring 7 are set up, so that the flat plate 4 can be adaptively adjusted as the winding diameter changes, ensuring that the flat plate 4 is always stably pressed on the polyester film roll and has a good leveling effect. In order to ensure the stability of the flat plate 4, a pressing plate 5 is set up to press one end of the flat plate 4 to prevent one end of the flat plate 4 from tilting. Through the set movable groove 8 and linkage block, the pressing plate 5 can be raised and lowered synchronously with the flat plate 4. When necessary, the knob 14 is turned to drive the screw 16 to rotate, and the slider 17 and the stretching clamp 13 are driven to rise and fall synchronously through the threaded connection relationship, so as to clamp and position polyester films of different thicknesses, and ensure that the polyester film is stretched to avoid wrinkles.
