a shrinking machine

Abstract

The invention discloses a shrinking machine, the upper frame and the base enclose a heat shrinkable space, the base is provided with a conveyor belt, the base is provided with a heating mechanism and an air outlet mechanism, and the upper frame forms a material inlet and outlet at both ends of the conveyor belt. Side air outlets are arranged on the left and right sides, and a wind deflector that can be rotated to adjust the angle is arranged above the side air outlet; a first windshield is arranged above the heating mechanism, and several windshields are arranged along the material conveying direction. At the air outlet, a second windshield is arranged under the first windshield, and the second windshield is arranged along the material conveying direction with a number of air guides corresponding to the air outlet. The second windshield can slide It is set and driven by the second driving mechanism to slide along the material conveying direction, and adjust the overlapping size of the air guide port and the air outlet. The invention uses the control module to automatically adjust the angle of the air outlet on both sides and the air volume of the air outlet below, so that films of different specifications can achieve better thermal shrinkage effects.

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
