Description

Technical Field

[0001] The utility model relates to the technical field of paper product processing, in particular to a colloid coating mechanism for paper products. Background Art

[0002] Paper products are products made from paper as the main raw material. They are widely used in many fields such as daily life and industry. In life, writing and printing paper products such as books, notebooks and newspapers can be seen everywhere. Packaging paper products include cartons, paper bags and packaging boxes. Sanitary products such as toilet paper, napkins and wet wipes are also necessities of life. The paper product colloid coating mechanism is a kind of equipment that plays an important role in the production process of paper products. The efficient operation of the paper product colloid coating mechanism is crucial to improving the quality and production efficiency of paper products. It can make the papers bond better and enhance the strength and durability of paper products. Whether in the production of packaging paper products such as cartons, paper bags, packaging boxes, or in the production of writing and printing paper products such as notebooks and books, the colloid coating mechanism plays an indispensable role.

[0003] The traditional colloid coating mechanism is generally composed of a glue tank and a coating roller. The colloid is applied to the surface of the paper product and then spread through the coating roller. The colloid on the surface of the paper product is evenly coated on the surface of the paper product, so that the paper products can be bonded to each other.

[0004] However, the traditional paper product colloid coating mechanism has a single structure. When the paper product is too thick, it will get stuck when passing through the coating roller and the colloid cannot be coated. When the paper product is too thin, the paper product cannot be adhered to and coated when passing through the coating roller. The coating roller cannot automatically adapt to paper products of different thicknesses for adhesion and coating, resulting in uneven coating on the surface of paper products of different thicknesses. Therefore, it is necessary to replace coating rollers of different diameters. In the existing technology, manual labor is required to replace the coating rollers on site according to the thickness of different batches of paper products to achieve the effect of coating paper products of different thicknesses. The process consumes manpower and material resources to observe the coating status of each batch of paper products, which not only reduces work efficiency but also increases production costs. Therefore, a paper product colloid coating mechanism is proposed to solve the above problems. Utility Model Content
