Description

Technical Field

[0001] The utility model belongs to the technical field of heat shrink film production, in particular to a heat shrink film shaping device. Background Art

[0002] Heat shrink film is used for the sale and transportation of various products. Its main function is to stabilize, cover and protect the products. Shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. The principle of blow molding by film blowing machine is to press the plastic raw material from the front end of the screw extruder into the die head, so that the highly elastic plastic raw material is extruded into a tube through the die head, and the compressed air introduced from the bottom of the die head is used to blow the tube into a larger diameter tubular original film evenly and freely. At the same time, the tubular original film is longitudinally stretched in the process of upward traction and gradually cooled.

[0003] In the prior art, Chinese patent publication number CN220784868U discloses a heat shrink film cooling and shaping device, which includes a cooling tank and a cooling table, and the cooling tank is equipped with a spray chamber and an air cooling box, and the cooling table is equipped with a support frame, a material guide roller and a cold air box. The heat shrink film can be completely cooled and shaped by the heat shrink film cooling and shaping device, and the cooling effect is relatively ideal.

[0004] However, in actual use, a lot of moisture will remain on the film after spraying in the cooling tank. The above technology solves the problem of moisture remaining on the heat shrink film through a subsequent air cooling box and absorbent cotton connected to the guide roller. However, this method cannot effectively remove moisture and has low efficiency. The absorbent cotton on the guide roller needs to be replaced frequently, and the guide rollers often need to be replaced one by one during replacement, which reduces the efficiency of film production.

[0005] A heat shrink film shaping device is now provided to improve the above problem. Utility Model Content

[0017] 2) The utility model sets up a cooling groove, which makes it easy for the spray chamber to draw water from the cooling groove, and the water after spraying falls into the cooling groove again, so as to achieve the purpose of reusing cooling water.

[0018] 3) The utility model achieves the water absorption effect by flatly laying the absorbent cotton in the water absorption box. Not only is the operation simple when replacing the absorbent cotton, but the flat laying can also increase the contact area between the absorbent cotton and the membrane, thereby increasing the water absorption effect.

[0019] 4) The second, third and fourth conveyor rollers are set at different heights so that the film will have a certain inclination when passing through the second, third and fourth conveyor rollers. The residual moisture on the film that has just been sprayed will slide down along the film, and the first air cooling box will blow air to improve the drying effect on the film surface.
