Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a conveying device of a laminating machine. Background Art

[0002] Laminating machines can be divided into two categories: instant laminating machines and pre-coating laminating machines. It is a special equipment for paper and film. The instant laminating machine includes three parts: gluing, drying and hot pressing. It has a wide range of applications and stable and reliable processing performance. It is currently a widely used laminating equipment in China. The pre-coating laminating machine has no gluing and drying parts, is small in size, low in cost, and is flexible and convenient to operate. It is not only suitable for laminating processing of large quantities of printed materials, but also suitable for laminating processing of small batches and scattered printed materials such as automated desktop office systems. It has great development prospects. Existing laminating machines generally include a paper feeding mechanism and a laminating mechanism. The paper feeding mechanism transmits the roll of paper to the laminating mechanism, and then the laminating mechanism is used to laminate it, cut it, and finally send it out.

[0003] In the process of delivering the paper roll to the laminating mechanism, the paper roll may be stacked and folded during transportation due to the non-fitting of the paper roll and possible creases. The general conveying device, i.e., the conveying roller, has a large relative contact area with the paper roll and a relatively uniform force. However, it cannot effectively straighten out the stacked and folded paper rolls or the existing creases in the paper rolls, and the folded paper rolls may even be folded again, affecting the subsequent laminating process.

[0004] For example, the patent with publication number CN219544300U proposes an anti-curling mechanism for a laminating machine, which uses an elastic pad to elastically support the contact between the sponge layer and the laminating paper, thereby ensuring the contact effect between the laminating paper and the sponge layer, ensuring the water absorption effect of the laminating paper, and ensuring the anti-curling effect of the printed matter during the laminating operation. It prevents the roll paper from getting stuck and folding by filling the gap between the continuous conveying rollers, and the conveying rollers are still cylindrical, so the roll paper that has been piled up and folded cannot be effectively transported. Utility Model Content

[0005] The utility model aims to provide a conveying device for a laminating machine to solve the existing technical problems.

[0006] The embodiments of the present invention are implemented by the following technical solutions:

[0007] A conveying device for a laminating machine includes a conveying roller for transporting a roll of paper, the conveying roller is provided with a curved surface layer having different curvatures for rotating and oscillating the roll of paper to flatten the folded roll of paper, and the conveying roller also includes a plurality of groups of protruding rollers for lifting the curved surface layer to form a convex surface.

[0008] Preferably, the conveying roller is provided with a groove for accommodating and limiting the protruding roller and a connecting rod for connecting the protruding roller.

[0009] Preferably, the connecting rod includes a first connecting rod for connecting the protruding roller, a second connecting rod for connecting the rotating shaft of the conveying roller, and an elastic member for connecting the first connecting rod and the second connecting rod.

[0012] Preferably, the groove is configured to have a depth greater than the radius of the protruding roller, and an opening smaller than the radius of the protruding roller.

[0013] Preferably, the conveying roller further comprises an elastic layer for tightening the curved layer and providing a buffer therefor.

[0014] The convex roller arranged on the conveying roller creates a convexity on the curved surface layer, so that when the conveying roller rotates to the convex roller facing the roll paper, the folded roll paper will be vibrated due to the influence of the convex curved surface layer, and at the same time, the top layer of roll paper will be arranged and sent out when the convex roller rotates, effectively arranging and flattening the folded roll paper with creases;

[0015] By means of the elastic strength of the curved surface layer and the elastic member, the extension and retraction length of the protruding roller is balanced within a suitable range, and the protruding height is adjusted.

[0016] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0017] 1. The utility model can vibrate the folded paper rolls, and at the same time, the top layer of paper rolls can be arranged and sent out when the protruding rollers rotate, effectively arranging and flattening the folded paper rolls with creases;

[0018] 2. The utility model uses the elastic strength of the curved surface layer in combination with the elastic member to balance the telescopic length of the protruding roller within a suitable range and adjust the protruding height. BRIEF DESCRIPTION OF THE DRAWINGS
