Embodiment 1

[0039] Such as figure 1 As shown, a woven bag of the present invention, the woven bag 100 is laminated on both sides, the bottom is sealed with a seal 103, and there is no text and / or pattern information 101 on the film.

[0040] Such as Figure 3-Figure 4 As shown, a woven bag double-sided dry-type laminating machine includes a woven bag feeding mechanism 200 for conveying the woven bag 100, a film feeding mechanism 300 for conveying the film, and a film feeding mechanism 300 for laminating the film on the woven bag. The dry compounding mechanism 400 on 100, the rolling mechanism 500 for the retroperitoneal woven bag 100 rolling and the feeding mechanism 200 for controlling the woven bag, the film feeding mechanism 300, the dry compounding mechanism 400, the winding mechanism 500 and the compounding mechanism The controller of the film calibration mechanism 600 working together. The film feeding mechanism 300 is divided into two groups, which are symmetrically arranged on bo...

Embodiment 2

[0046] This embodiment is mainly aimed at the situation that both sides of the film with text and / or pattern information 101 are laminated simultaneously. Such as figure 2 As shown, a woven bag of the present invention, the woven bag 100 is laminated on both sides, the bottom is sealed with a seal 103, and the same text and / or pattern information 101 is arranged at equal intervals on the film used for laminating, and each The position corresponding to the group text and / or pattern information 101 is provided with an alignment mark 102. In the figure, the solid line represents the alignment mark 102 on the front side, and the dotted line represents the alignment mark 102 on the reverse side. The alignment mark 102 described in this embodiment is a color code The film on each side is provided with two color codes, one is located on the upper part of the text and / or pattern information 101, and the other is located on the lower part of the text and / or pattern information 101. T...

Embodiment 3

[0056] This embodiment is mainly aimed at the situation that both sides of the film with text and / or pattern information 101 are laminated simultaneously. Such as figure 2As shown, a woven bag of the present invention, the woven bag 100 is laminated on both sides, the bottom is sealed with a seal 103, and the same text and / or pattern information 101 is arranged at equal intervals on the film used for laminating, and each The position corresponding to the group text and / or pattern information 101 is provided with an alignment mark 102. In the figure, the solid line represents the alignment mark 102 on the front side, and the dotted line represents the alignment mark 102 on the reverse side. The alignment mark 102 described in this embodiment is a color code The film on each side is provided with two color codes, one is located on the upper part of the text and / or pattern information 101, and the other is located on the lower part of the text and / or pattern information 101. Th...

Abstract

The invention provides a double-faced dry laminating combination machine for a woven bag, and a laminating method. The double-faced dry laminating combination machine for the woven bag comprises a woven bag feeding mechanism, film feeding mechanisms, a dry laminating mechanism, a rolling mechanism, a laminating calibration mechanism and a controller, wherein the woven bag is conveyed to the dry laminating mechanism by the woven bag feeding mechanism; meanwhile, the film is conveyed to the dry laminating mechanism by the film feeding mechanisms on two sides; the film is compounded on two sides of the woven bag by the dry laminating; finally, the rolling mechanism is used for carrying out rolling. In a whole laminating process, an identification detection mechanism is used for detecting whether alignment identification on two sides of the woven bag is within an error range which needs to be aligned or not in real time; when an alignment requirement is met, a controller controls each mechanism to continuously carry out lamination; when the alignment requirement is not met, the controller controls a guide roller calibration component to regulate the tension degree of the film according to the result of the identification detection mechanism.

Description

technical field [0001] The invention relates to the technical field of dry laminating machines, in particular to a double-sided dry laminating combined machine for woven bags and a laminating method. Background technique [0002] Woven bag is a kind of packaging bag made by cylindrical weaving. In some packaging fields, such as food, the packaged product needs to block the external moisture and oxygen from entering the interior, so that the product will not be oxidized by water vapor and oxygen. , to avoid being attacked by microorganisms, and to achieve long-term freshness preservation. Therefore, it is necessary to coat a layer of film on the outside of the woven bag for protection. In the prior art, lamination includes two methods: dry lamination and extrusion casting lamination. Among them, dry lamination is to apply solvent-diluted adhesive on the substrate after it dries, and to laminate it with other films by applying pressure with a heating roller. . The adhesive f...
