Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene products, and in particular to a bib production line. Background Technology

[0002] Existing bib production lines suffer from several problems: Firstly, the automation level of the production process is low, with many steps relying on manual operation. This not only leads to low production efficiency but also introduces errors, resulting in inconsistent product quality. For instance, in the unwinding, splicing, and tension adjustment of materials such as toilet paper and non-woven fabrics, manual operation makes it difficult to ensure precise connection and stable operation of each step, easily leading to problems such as material breakage and uneven tension, which in turn affects the overall quality of the bibs.

[0003] On the other hand, existing production lines are inadequate in terms of coordination among various production stages. The transmission and processing of different materials on the production line lack effective integration and coordination, which can easily lead to material accumulation and poor transmission during the production process, reducing production efficiency and increasing production costs.

[0004] With the market's increasing demands for the quality and production efficiency of bibs, developing a highly automated bib production line with good coordination among all stages and precise control of key processes is of great practical significance. Utility Model Content

This allows the distance between the two pressure rollers 105 to be flexibly adjusted according to different specifications of bibs, meeting diverse production needs and improving the versatility and adaptability of the production line.

[0050] Furthermore, the folding pressure plate assembly 484 includes a bracket 201, a vertical rod 202 disposed on the bracket 201, a pressure plate 203 disposed at the lower end of the vertical rod 202, an inclined plate 204 disposed at the front end of the pressure plate 203, and guide rods 205 disposed on the vertical rod 202 and distributed on the upper side of the pressure plate 203.

[0051] Meanwhile, the folding mechanism 51 includes a third pulley assembly 511, a fourth pulley assembly 512, a fifth pulley assembly 513, a sixth pulley assembly 514, an insert plate 515, and a linear drive device 516.
