Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] When the film is laminated on paper or cardboard, and the product 200 is packaged through the space surrounded by the film and the corresponding paper or cardboard, the length of the film (that is, the length of the film in figure 1 The larger the dimension in the second direction), the higher the height of the product 200 that can be adapted (that is, the dimension in the first direction).

[0048] Apparently, in figure 1 In the second direction, th...

Abstract

The invention relates to the technical field of packaging, and discloses a film covering device and a film covering method.The film covering device comprises a rack, a film adsorption roller, a bearing body conveying unit and a slow stop assembly; when the film adsorption roller rotates to a first state and the bearing body is located at a first station, the film adsorption roller moves in the direction close to the bearing body conveying unit, so that the front end of the cut film is bonded with the front end of the bearing body; when the film adsorption roller rotates to a second state and the bearing body is located at a second station, the film adsorption roller moves in the direction close to the bearing body conveying unit, so that the rear end of the cut film is bonded with the rear end of the bearing body; the slow stop assembly can reduce the moving speed of the bearing body or enable the bearing body to stop moving after the front end of the cut film is bonded with the front end of the bearing body and before the rear end of the cut film is bonded with the rear end of the bearing body. According to the film covering device and the film covering method, the problem that the lengthening length of the film is greatly limited is solved.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a film covering device and a film covering method. Background technique [0002] Lay a film on paper or cardboard, and package the product through the space surrounded by the film and the corresponding paper or cardboard (such as Figure 1-Figure 3 Shown) is a widely used product packaging method. [0003] In the process of laminating film and paper, in one way, the pretreatment of the film is realized through a roller assembly with a specific shape. Specifically, the roller with a convex part and the roller with a concave part are engaged and driven, and the film passes through the two rollers. In the other way, in order to improve production efficiency, the film is not cut in advance, but is conveyed continuously, and the film is piled up by the speed difference, and the film is combined with the corresponding paper or cardboard Then proceed to overall cutting. In the forme...
