Description

Technical Field

[0001] The utility model belongs to the technical field of paper cup production, in particular to a coating device in a disposable paper cup making machine. Background Art

[0002] Paper cup laminating is to melt plastic particles and coat them on the surface of paper to make the paper oil-proof and waterproof (relatively). The paper is then pressed into cups by cup-making equipment. The disposable paper cups commonly used in daily life are made of laminated paper. The most important production equipment in the production process of laminated paper is the laminating machine.

[0003] The conventional laminating machine has a fixed nozzle position, so one nozzle can only laminate paper of one width, and has low applicability. In addition, the laminating machine is usually equipped with two winding drums for winding and releasing paper. The fabric that can be wound (released) by the winding drum in one rotation is determined by the diameter of the paper on the outer circle of the winding drum. However, as the paper is wound (released), the diameter of the paper on the outer circle of the winding drum keeps changing, so it is difficult to control the winding (releasing) of the paper. If the paper is wound too slowly and the paper is released too quickly, wrinkles are likely to appear on the paper. At the same time, if the paper is wound too quickly and the paper is released too slowly, the paper is likely to be torn. In order to solve the above problems, a laminating device in a disposable paper cup making machine is provided.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content
