[0006] The tension adjusting mechanism includes a left adjusting disk rotatably connected to one of the side plates, a right adjusting disk rotatably connected to the other side plate. Both the right adjusting disk and the left adjusting disk are arranged between the two side plates. Two tension adjusting rods with an included angle of 180° are connected between the left adjusting disk and the right adjusting disk. A worm gear for controlling its rotation is rotatably connected to the left adjusting disk or the right adjusting disk. A worm meshing with the worm gear is rotatably connected to the side plate, and one end of the worm is drivingly connected to a hand wheel for controlling its rotation.

[0007] The utility model is further arranged as: The lower cooling roller is arranged directly below the upper cooling roller.

[0008] The utility model is further arranged as: The tension adjusting mechanism is arranged at the middle position between the upper cooling roller and the lower cooling roller.

[0009] The utility model is further arranged as: A feeding conveyor roller close to the upper cooling roller is rotatably connected between the side plates; A discharging conveyor roller close to the lower cooling roller is rotatably connected between the side plates.

[0010] The utility model is further arranged as: The tension adjusting rod has a round rod structure.

[0011] In summary, the utility model has the following beneficial effects: The cooling device for processing PVC decorative films according to the utility model, by reasonably adjusting the tension adjusting mechanism, enables the PVC decorative film being conveyed to continuously adhere to the surface of the cooling roller, ensuring the cooling effect while realizing the function of stable conveyance.

[0015] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation solutions of the utility model will be described below in conjunction with specific embodiments. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the utility model.

[0016] The utility model will be further described below in conjunction with the drawings and preferred embodiments.

[0017] Embodiment 1

[0018] Referring to Figures 1 to 3 as shown, a cooling device for processing PVC decorative films according to this embodiment includes a base 1, two side plates 2 arranged symmetrically left and right are provided on the base 1, an upper cooling roller 3 and a lower cooling roller 4 are rotatably connected between the side plates 2, and a tension adjusting mechanism 5 is provided between the lower cooling roller 4 and the upper cooling roller 3;

[0019] The tension adjusting mechanism 5 includes a left adjusting disk 51 rotatably connected to one of the side plates, a right adjusting disk 52 rotatably connected to the other side plate. The right adjusting disk 52 and the left adjusting disk 51 are both arranged between the two side plates 2. Two tension adjusting rods 53 with an included angle of 180° are connected between the left adjusting disk 51 and the right adjusting disk 52. A worm gear 54 for controlling its rotation is rotatably connected to the left adjusting disk 51 or the right adjusting disk 52. A worm 55 rotatably connected to the side plate is engaged with the worm gear 54, and one end of the worm 55 is drivingly connected to a hand wheel 56 for controlling its rotation.

[0020] Further, the lower cooling roller 4 is disposed directly below the upper cooling roller 3; the tension adjusting mechanism 5 is disposed at the middle position between the upper cooling roller 3 and the lower cooling roller 4.

[0021] Further, a feed conveyor roller 6 close to the upper cooling roller 3 is rotatably connected between the side plates 2; a discharge conveyor roller 7 close to the lower cooling roller 4 is rotatably connected between the side plates 2.

[0022] Further, the tension adjusting rod 53 has a round rod structure.

[0023] In this embodiment, the conveyed PVC decorative film sequentially passes through the feed conveyor roller 6, the upper cooling roller 3, the tension adjusting mechanism 5, the lower cooling roller 4, and the discharge conveyor roller 7. During this period, if the tension of the conveyed PVC decorative film decreases, the handwheel 56 needs to be rotated clockwise. Through the mechanism transmission, the tension adjusting rod 53 further presses the PVC decorative film; if the tension of the conveyed PVC decorative film increases, the handwheel 56 needs to be rotated counterclockwise. Through the mechanism transmission, the tension adjusting rod 53 moves away from the PVC decorative film to reduce the extrusion.

[0024] The cooling device for processing PVC decorative films according to the present utility model can continuously keep the conveyed PVC decorative film tightly attached to the roller surface of the cooling roller by reasonably adjusting the tension adjusting mechanism, ensuring the cooling effect while realizing the function of stable conveyance. The overall function is perfect and the practicability is strong.
