Description

Technical Field

[0001] This utility model relates to the field of synthetic leather production technology, and in particular to a vacuum constant temperature synthetic leather pre-curing device. Background Technology

[0002] Synthetic leather is a leather substitute material manufactured artificially. It is usually made by coating various polymers onto a textile or non-woven fabric base. It has a similar appearance and some properties to natural leather. In the production process of synthetic leather, a pre-curing device is needed to pre-cur the synthetic leather. Its main function is to allow the coating material of the synthetic leather to undergo a preliminary cross-linking reaction with the base, forming certain physical and chemical properties, laying the foundation for subsequent processing steps.

[0003] Currently, existing synthetic leather pre-curing devices often cannot easily adjust the tension of synthetic leather during pre-curing. During the transmission process, the tension on the synthetic leather is easily unstable, which may lead to problems such as wrinkles and loosening, affecting the quality of the synthetic leather. At the same time, due to the influence of wrinkles and other factors, the cross-linking reaction of the coating material in this area may be incomplete, resulting in decreased chemical stability and affecting the pre-curing effect of the synthetic leather.
