Shrinking machine

Abstract

The invention discloses a shrinking machine. A heat shrinkage space is defined by an upper frame and a base of the shrinking machine, a conveying belt is arranged on the base, a heating mechanism and an air outlet mechanism are arranged in the base, the upper frame forms material inlets and outlets in the two ends of the conveying belt, side air outlets are formed in the left side and the right side of the conveying belt, and an air guide plate with the angle capable of being rotationally adjusted is arranged above the side air outlets. A first air baffle is arranged above the heating mechanism, a plurality of air outlets are formed in the first air baffle in the material conveying direction, a second air baffle is arranged below the first air baffle, and a plurality of air guide openings corresponding to the air outlets are formed in the second air baffle in the material conveying direction. The second air baffle is slidably arranged and is driven by a second driving mechanism to slide in the material conveying direction, and the overlapping size of the air guide openings and the air outlets is adjusted. A control module is used for automatically adjusting the air outlet angles on the two sides and the air outlet volume below, so that films of different specifications achieve a better heat shrinkage effect.

Description

technical field [0001] The invention relates to the field of product packaging, in particular to a shrinking machine. Background technique [0002] Heat shrink packaging machine is one of the more advanced packaging machinery in the market. The shrink film is used to wrap the product outside, and the shrink film is heated to make the product tightly wrapped, which fully displays the appearance of the product, improves the product's displayability, and increases the beauty and value. [0003] In the shrinking machine in the prior art, the air guiding mechanism and the heating mechanism are arranged under the conveying space, and the conveying space is conveyed by the conveyor belt to convey the product covered with the film, and the heat generated by the heating mechanism is blown upward through the air guiding mechanism to heat the film. Shrinkage; the general machine only blows upwards, and does not limit the direction of the wind. When dealing with products of different s...

Problems solved by technology

[0003] In the shrinking machine in the prior art, the air guiding mechanism and the heating mechanism are arranged under the conveying space, and the conveying space is conveyed by the conveyor belt to convey the product covered with the film, and the heat generated by the heating mechanism is blown upward through the air guiding mechanism to heat the film. Shrinkage; the general machine only blows upwards, and does not limit the direction of the wind. When dealing with products of different specifications, there may be conveying space because the hot air cannot blow to the side or top of the product and the film well. Due to the large size of the film itself, there will be uneven heating of the upper and lower sides of the film and the surrounding area, which will affect the shrinkage quality of the film; on the other hand, the wind blowing upwards does not limit the size of the wind. If the hot air is too large or too small, the product and the film cannot be well placed in a proper heating environment, and the film will be heated unevenly or the degree of shrinkage will be different, which will affect the shrinkage quality of the film
