Description

TECHNICAL FIELD

[0001] The present application relates to the field of disposable hygiene products, in particular to a saliva wipe production line. BACKGROUND

[0002] The existing saliva wipe production line has many problems: on the one hand, the degree of automation of the production process is low, and many links rely on manual operation, which not only leads to low production efficiency, but also manual operation is easy to introduce errors, so that the product quality is uneven. For example, in the unwinding, cutting and tension adjustment of materials such as toilet paper and non-woven fabric, manual operation cannot guarantee the precise connection and stable operation of each link, and is prone to material breakage, uneven tension and other problems, thereby affecting the overall quality of the saliva wipe.

[0003] On the other hand, the existing production line has deficiencies in the coordination of each production link, and the transmission and processing of different materials on the production line lack effective integration and coordination, which leads to material accumulation, poor transmission and other problems in the production process, reduces the production efficiency, and also increases the production cost.
