The traditional heat shrink film production process generally includes the heating, shrinking, and cooling process of the heat shrink film. The cooling process is a crucial step in the heat shrink film processing, which directly affects the film's shaping quality, shrinkage effect, and production efficiency.

[0003] For example, patent (CN214926309U) discloses a production and shaping device for heat shrinkable film. The utility model has the advantages of being easy to use, being able to prevent dust from adhering to the heat shrinkable film, and having a good cooling and shaping effect.

[0004] When using the above technology, it was found that the following technical problems exist in the existing technology: the cooling path of the existing air-cooled cooling system is usually relatively fixed, and the path cannot be flexibly adjusted according to the cooling requirements of different film materials, resulting in difficulty in accurately controlling the cooling effect. The stress state of the film during the cooling process is relatively single, and the shaping of the film material may be affected by uneven cooling, causing wrinkles and uneven stretching on the film surface, affecting the final shaping effect. For this reason, we designed a heat shrink film cooling and shaping equipment to provide another technical solution to the above technical problems. Utility Model Content

[0029] A vibration mechanism for guiding the roller 7 to vibrate is also provided on one side of the cooling box 1;

[0030] A blower 6 is bolted to the other side of the cooling box 1. A U-shaped ventilation pipe 3 is provided at the output end of the blower 6. The top and bottom of the U-shaped ventilation pipe 3 are connected to the cooling box 1. Through the operation of the blower 6, the outside air can enter the interior of the U-shaped ventilation pipe 3, and then the air inside the U-shaped ventilation pipe 3 is injected into the interior of the cooling box 1, so that the heat shrink film can be cooled, so as to facilitate the cooling and shaping of the heat shrink film.

[0031] The rotation mechanism includes a transverse hydraulic cylinder 13, which is fixed inside the rectangular frame 4. The output end of the transverse hydraulic cylinder 13 is rotatably connected to a rectangular transmission column 12, and one end of the rectangular transmission column 12 is rotatably connected to a rectangular rotation column 11. A longitudinal rotation shaft 10 is fixed inside one end of the rectangular rotation column 11. The longitudinal rotation shaft 10 passes through the interior of the rectangular frame 4 and is rotatably connected to the rectangular frame 4 via a bearing. The longitudinal rotation shaft 10 is close to one side of the rectangular connecting plate 8 and is fixedly connected to the rectangular connecting plate 8.

[0032] The longitudinal rotating shaft 10 passes through the interior of the rectangular frame 4 and is rotatably connected to the rectangular frame 4 via a bearing. The arrangement of the bearing enables the longitudinal rotating shaft 10 to rotate within the rectangular frame 4. The rotation of the longitudinal rotating shaft 10 enables the rectangular connecting plate 8 to rotate, thereby enabling the two guide rollers 7 to rotate with the longitudinal rotating shaft 10 as the center of the circle.

[0033] Here, the operation of the transverse hydraulic cylinder 13 enables the output end of the transverse hydraulic cylinder 13 to push the rectangular transmission column 12 to move. The movement of the rectangular transmission column 12 enables the rectangular rotation column 11 to drive the longitudinal rotation shaft 10 to rotate inside the rectangular frame 4. The rotation of the longitudinal rotation shaft 10 enables the rectangular connecting plate 8 to rotate. The rotation of the rectangular connecting plate 8 enables the two guide rollers 7 to rotate, thereby increasing the movement path of the heat shrink film inside the cooling box 1, so that the path of the heat shrink film inside the cooling box 1 can be adjusted according to the cooling efficiency.

[0034] The vibration mechanism includes two vibration motors 5, and vibration motors 5 are provided at both ends of one side of the rectangular frame 4. Rectangular fixed blocks 17 are also fixed at both ends inside the rectangular frame 4. The interior of the rectangular fixed block 17 is slidably connected to a vertical polished rod 15.

Vertical rigid springs 16 are provided at the top and bottom of the rectangular fixed block 17 and on the outside of the vertical polished rod 15. The operation of the vibration motor 5 enables the rectangular sliding plate 9 to slide vertically inside the cooling box 1. The sliding of the rectangular frame 4 enables the rectangular fixed block 17 to slide on the outside of the vertical polished rod 15. The sliding of the rectangular fixed block 17 causes the vertical rigid spring 16 to be deformed under force.

[0035] A rectangular sliding plate 9 is fixed to the top and bottom of the rectangular frame 4. A vertical slide groove is provided inside the cooling box 1. The rectangular sliding plate 9 is located inside the vertical slide groove and is slidably connected to the cooling box 1 through the vertical slide groove. The vertical slide groove is provided so that the rectangular sliding plate 9 can slide vertically inside the cooling box 1.

[0036] Here, the operation of the vibration motor 5 enables the rectangular frame 4 to vibrate inside the cooling box 1, thereby enabling the rectangular sliding plate 9 to slide vertically inside the cooling box 1. The vibration of the rectangular frame 4 enables the rectangular fixed block 17 to slide vertically on the outside of the vertical light rod 15, thereby enabling the vertical rigid spring 16 to be deformed under force. The vibration of the guide roller 7 can enhance the vibration of the heat shrink film.

[0037] It can extend the cooling path of the heat shrinkable film, flexibly adjust the path length according to different cooling requirements, and enable the heat shrinkable film to vibrate during the cooling process to improve the shaping efficiency and quality of the heat shrinkable film. The heat shrinkable film can not only obtain more uniform and effective cooling, but also achieve surface vibration during the cooling process, further improving the shaping effect of the film material and meeting the production needs of different products and film materials.

[0038] During use: the operation of the transverse hydraulic cylinder 13 enables the output end of the transverse hydraulic cylinder 13 to push the rectangular transmission column 12 to move, and the movement of the rectangular transmission column 12 enables the rectangular rotation column 11 to drive the longitudinal rotation shaft 10 to rotate inside the rectangular frame 4. The rotation of the longitudinal rotation shaft 10 enables the rectangular connecting plate 8 to rotate, and the rotation of the rectangular connecting plate 8 enables the two guide rollers 7 to rotate, thereby increasing the movement path of the heat shrink film inside the cooling box 1, so as to facilitate adjusting the path of the heat shrink film inside the cooling box 1 according to the cooling efficiency;

[0039] The operation of the vibration motor 5 enables the rectangular frame 4 to vibrate inside the cooling box 1, thereby enabling the rectangular sliding plate 9 to slide vertically inside the cooling box 1. The vibration of the rectangular frame 4 enables the rectangular fixed block 17 to slide vertically on the outside of the vertical light rod 15, thereby causing the vertical rigid spring 16 to be deformed under force. The vibration of the guide roller 7 can enhance the vibration of the heat shrink film.
