Spraying cooling device for packaging film

Abstract

The invention discloses a spraying cooling device for a packaging film. The spraying cooling device comprises a cooling box, a first guide roller is arranged on the right side of the interior of the cooling box, a second guide roller is arranged on the upper left portion of the first guide roller, a third guide roller is arranged on the lower left portion of the second guide roller, and a fourth guide roller is arranged on the upper left portion of the third guide roller. The second guide roller, the third guide roller and the fourth guide roller sequentially form a V shape, so that a packaging film conveyed on the outer surfaces of the three guide rollers is also in a V shape, on one hand, the conveying time of the packaging film in the cooling box is prolonged, and the water spraying cooling time is also prolonged; and on the other hand, water can flow downwards along the surface of the packaging film conveniently, due to the fact that a plurality of first spray heads and a plurality of second spray heads are arranged on the upper surface and the lower surface of the packaging film, the multiple first spray heads and the multiple second spray heads can continuously conduct water spraying cooling treatment on the upper surface and the lower surface of the packaging film at the same time, and the cooling effect is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of packaging films, in particular to a spray cooling device for packaging films. Background technique [0002] The packaging film is mainly composed of several different grades of resin mixed and extruded. It is puncture-resistant, super-strength and high-performance. It wraps the goods stacked on the pallet to make the package more stable and tidy, and has a super waterproof effect. It is widely used in foreign trade export, papermaking, hardware, plastic chemical industry, building materials, food and pharmaceutical industries. When using packaging film to package items, the staff need to cut the roll of packaging film first. During the cutting process of packaging film High temperature will be generated. In order to avoid deformation of the packaging film due to excessive temperature, the packaging film needs to be cooled during the cutting process, so as to improve the quality of the packaging film after...

AI Technical Summary

Problems solved by technology

[0003] The existing cooling devices generally simply spray water on the upper surface of the packaging film to cool down, but the lower surface does not spray water to cool down, resulting in an unsatisfactory cooling effect, and the surface of the packaging film after water spraying will be very wet, and The current cooling device does not process it before rewinding, so that the water in the rolled packaging film after winding will affect the quality of the packaging film
