Description

Technical Field

[0001] The utility model relates to the technical field of synthetic leather manufacturing, in particular to a winding device for leather dry production. Background Art

[0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as a substitute. It's typically made with an impregnated non-woven fabric as the mesh layer and a microporous polyurethane layer as the grain layer. Both the front and back of synthetic leather closely resemble leather and offer a certain degree of breathability, making it closer to natural leather than regular artificial leather. Therefore, it's widely used in a variety of applications, including footwear, bags, interior decoration, and balls.

[0003] Existing synthetic leather can be made by two different processing methods: wet impregnation and dry coating. The dry coating process is to first unwind the base fabric, then introduce the unwound base fabric into the feed cloth storage rack, and then lead it from the feed cloth storage rack to the coating machine. The coating is evenly applied to the base fabric by the coating machine, and then it is sent to the drying equipment for drying. Then, the pattern is printed on the base fabric, and then the base fabric is sent to the discharge cloth storage rack, and finally introduced to the wind-up roller by the discharge cloth storage rack, thus completing the dry coating process of the synthetic leather.

[0004] However, in the actual production process, static electricity is inevitably generated due to the continuous contact and friction between the synthetic leather and the roller when it is rolled up. As a result, dust and impurities in the air are adsorbed onto the surface of the synthetic leather due to static electricity, which not only affects the surface treatment effect of the synthetic leather, but also reduces the appearance quality of the final product.

[0005] In view of this, the inventor conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content

The cylinder can also be used to adjust the distance between the static eliminator and the synthetic leather, ensuring the effect of static elimination. BRIEF DESCRIPTION OF THE DRAWINGS
