Description

Technical Field

[0001] The utility model relates to a cooling and shaping device, in particular to a cooling and shaping device for a heat shrinkable film. Background Art

[0002] Heat shrink film is a commonly used packaging material, usually used to package various products such as food, beverages, cosmetics, medicines, and daily necessities. It is usually made of polyethylene (PE) and has excellent heat resistance and flexibility. The heat shrink film is heated and shrunk during the packaging process, and can fit tightly to the surface of the packaged object, playing a role in protection, sealing, beautification, and anti-counterfeiting. During the processing of the heat shrink film, it needs to be cooled, shaped, and rolled up. The heat shrink film is driven forward by the winding roller. During the movement, a water-cooled roller is used to cool and shape the heat shrink film. During the rolling process of the heat shrink film, the edge of the heat shrink film is easily offset inward, causing wrinkles in the heat shrink film, affecting the quality of the heat shrink film.

DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0015] Embodiment. A heat shrink film cooling and shaping device, comprising: Figure 1-3 As shown, it includes a frame 1, a reversing roller 2 is provided on one side of the upper end of the frame 1, a cooling chamber 3 is provided on one side of the reversing roller 2, a liquid accumulation box 4 is provided at the bottom of the cooling chamber 3, an atomizing nozzle 6 is provided at the inlet of the cooling chamber 3, a cooling roller 7 is provided on one side of the atomizing nozzle 6, a limiting component for limiting the position of the heat shrinkable film is provided on one side of the cooling roller 7, and two groups of wiping rollers 8 are arranged oppositely on one side of the limiting component; an air drying chamber 9 is provided on one side of the cooling chamber 3, a winding roller 10 is provided on one side of the air drying chamber 9, and a limiting component is provided on the winding roller 10.

[0016] The limiting assembly includes a supporting roller 11, a bidirectional screw rod 12 is arranged inside the supporting roller 11, a symmetrically arranged screw rod seat 13 is arranged on the bidirectional screw rod 12, a connecting block 14 is arranged on the screw rod seat 13, the connecting block 14 is connected to a fixed seat 15 outside the supporting roller 11, and a pressure roller 16 that can rotate relative to the fixed seat 15 is arranged on the fixed seat 15.

[0017] The air drying chamber 9 is provided with air drying ducts 17 which are arranged at the upper and lower sides of the heat shrinkable film, and the air drying ducts 17 are provided with air outlet nozzles 18 which are in the same direction as the width direction of the heat shrinkable film.

[0018] The wiping roller 8 is provided with a wiping sponge 19 , and one side of the wiping sponge 19 is provided with a scraper 20 corresponding to the wiping roller 8 .

[0019] The principle of the utility model: the application conveys the heat shrink film blown out by the film blowing machine through the reversing roller 2, and the heat shrink film then enters the cooling chamber 3. The coolant sprayed by the atomizing nozzle 6 in the cooling chamber 3 cools the heat shrink film. During the heat shrink film conveying process, the heat shrink film can be limited by the limiting component to prevent wrinkles at the edge of the heat shrink film. The application can drive the two-way screw 12 to rotate by setting a motor or a rocker connected to the end of the two-way screw 12. During the rotation of the two-way screw 12, the screw seat 13 can drive the fixed seat 15 sleeved outside the support roller 11 to move symmetrically with the center of the support roller 11 through the connecting block 14, so that it can be suitable for heat shrink films of various sizes, and the edge of the heat shrink film can be pressed. Further, the support roller is a support roller that uses its own weight together with the cooling roller 7 and the winding roller 10 to press the heat shrink film. After cooling, the heat shrink film will be wiped by the wiping roller 8 to remove the residual water on the surface, and the wiping sponge 19 will absorb the moisture on the surface of the heat shrink film. In the process of the wiping roller 8 rotating, the scraper 20 will squeeze the wiping sponge 19. The scraper on the upper wiping roller 8 is an L-shaped scraper with baffles at both ends. The baffles are provided with drainage holes to prevent the scraped water from falling on the heat shrink film again, so that the wiping sponge 19 maintains a low water content and can fully absorb the moisture on the surface of the heat shrink film. Then the heat shrink film will enter the air drying chamber 9, and the air sent by the air outlet 18 on the air drying duct 17 will blow the heat shrink film dry. Finally, the heat shrink film will be rolled up by the motor-driven winding roller 10. The winding roller 10 is provided with a limit assembly, which can further prevent the heat shrink film from wrinkling.
