Example Embodiment

[0038] Example one:

[0039] Such as figure 1 As shown, in a woven bag of the present invention, the woven bag 100 is double-sided with a film, 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 double-sided dry laminating machine for woven bags includes a woven bag feeding mechanism 200 for conveying a woven bag 100, a film feeding mechanism 300 for conveying a film, and a film feeding mechanism 300 for laminating the film on the woven bag The dry rewinding mechanism 400 on 100, the rewinding mechanism 500 for rewinding the retroperitoneal woven bag 100, and the rewinding mechanism 500 used to control the woven bag feeding mechanism 200, the film feeding mechanism 300, the dry rewinding mechanism 400, the rewinding mechanism 500 and the rewinding mechanism The film calibration mechanism 600 is a controller that works in cooperation. The film feeding mechanism 300 is composed of two ...

Example Embodiment

[0045] Embodiment two:

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

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...
