Description

Technical Field

[0001] The utility model relates to the field of synthetic leather production, in particular to a super-soft high-gloss paint-leather coating device for synthetic leather 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 material for it. It is usually made of an impregnated non-woven fabric as a mesh layer and a microporous polyurethane layer as a grain layer. Both the front and back sides of the synthetic leather are very similar to leather and have a certain degree of air permeability. It is closer to natural leather than ordinary artificial leather and is widely used in the production of shoes, boots, bags and balls. In the production process of synthetic leather, varnishing is a key process, the purpose of which is to provide one or more layers of coating for the synthetic leather to improve its appearance, durability and waterproofness. China's authorized utility model patent (Announcement No.: CN220335227U) discloses a leather spraying machine. In this device, when the leather is placed on the conveyor belt, it will first contact with the pressing roller, so that the unflattened part of the leather is flattened. After passing through the pressing roller, it will contact the pressing inclined surface of the fixed plate, and enter the bottom of the pressing plate through the guidance of the pressing inclined surface. Since the connecting space is smaller than the passing space, the leather is further flattened, and wrinkles are removed at the same time, completing the flattening of the leather.

[0003] However, the above device still has some shortcomings when in use: although the pressure roller extrude and flatten the synthetic leather, since the conveyor belt itself has a certain deformation ability, when the pressure roller applies pressure, the synthetic leather will squeeze the conveyor belt and cause it to deform, resulting in poor flattening quality of the synthetic leather by the pressure roller, and since the spacing between the pressure roller and the conveyor belt is not adjustable, it is difficult to be used for synthetic leathers of different thicknesses. Therefore, in view of the above situation, an ultra-soft high-gloss paint coating device for synthetic leather production is proposed. Utility Model Content
