Description

Technical Field

[0001] The utility model belongs to the technical field, and in particular relates to a folding structure for a folder-gluing machine that is compatible with products of different sizes. Background Art

[0002] In the packaging and printing industry, the application of the box gluing machine is the last step in the packaging box processing. It is to fold the printed and die-cut cardboard into shape and glue the edges. The machine box gluing replaces the manual box gluing method, reducing labor costs and improving efficiency.

[0003] The folder gluing machine mainly includes a paper feeding part, a correction part, a pre-folding part, a hook bottom, a main folding part and an output part. Among them, the main folding part is used to fold the cut cartons to make them folded and formed. In the prior art, the main folding part generally includes three groups of upper belt pressure rollers and three groups of lower belt transmission components. The paper transported from the hook bottom passes between the upper belt pressure rollers and the lower belt transmission components.

[0004] However, the existing three groups of upper belt pressure rollers and three groups of lower belt transmission assemblies can only move left and right, but cannot move up and down. As a result, when a smaller paper box needs to be produced by the box gluing machine, the upper belt pressure roller and the lower belt transmission assembly in the middle need to be completely removed, and the upper belt pressure rollers on both sides are moved closer to each other, and the lower belt transmission assemblies on both sides are moved closer to each other. This process takes a long time and is inefficient.

[0005] In view of this, the utility model aims to provide a folding structure compatible with products of different sizes for a box gluing machine, which can realize the automatic rise or sinking of at least one group of upper belt pressure rollers and the automatic rise or sinking of at least one group of lower belt transmission components through ingenious design. When it is necessary to produce a paper box with a smaller size, it is only necessary to make the upper belt pressure rollers of the group (preferably the group located in the middle) rise automatically, make the lower belt transmission components of the group (preferably the group located in the middle) sink automatically, and then bring other upper belt pressure rollers (preferably located on both sides) close to each other, and bring other lower belt transmission components (preferably located on both sides) close to each other. When it is necessary to produce a paper box with a larger size, it is possible to separate other upper belt pressure rollers (preferably located on both sides), separate other lower belt transmission components (preferably located on both sides), and then make the upper belt pressure rollers of the group (preferably the group located in the middle) fall automatically, and the lower belt transmission components of the group (preferably the group located in the middle) rise automatically. The whole process is simple and easy, takes less time, and is highly efficient. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
