Description

Technical Field

[0001] The utility model relates to the technical field of processing of waterborne PU synthetic leather, and particularly relates to a coating and forming device for waterborne PU synthetic leather. Background Art

[0002] Waterborne PU leather is made of waterborne polyurethane as raw material, with water replacing toxic solvents such as DMF. When processing synthetic leather, it needs to be coated by a coating and forming machine, and after coating, it needs to be dried in the sun, and then the synthetic leather is trimmed. This not only has low work efficiency, but also is time-consuming and laborious, increasing the labor cost.

[0003] In the prior art, in the patent document with the publication number of CN220888120U, a coating and forming device for waterborne PU synthetic leather is proposed, including: a frame, a plurality of rollers are equidistantly installed in the frame, a trimming mechanism and an auxiliary conveying mechanism are fixedly connected to the upper end of the frame, and the trimming mechanisms are respectively located at both ends of the frame, the auxiliary conveying mechanism is located between the trimming mechanism and the coating machine, a coating machine is arranged at one end of the frame, a second support leg is fixedly connected to the lower end of the coating machine, a first support leg is fixedly connected to the lower end of the frame, and the lower ends of the first support leg and the second support leg are on the same plane. It can trim the edge after the synthetic leather is coated, reduce the curling generated during trimming, and at the same time assist in moving the synthetic leather, reducing the work burden.

[0004] In order to solve the problem that the existing forming device trims the coating by a cutting knife, although the cutting knife can cut the coating, it is easy to cause the edge of the coating to curl, affecting the appearance of the coating. The prior art adopts the method of making a circular knife body rotate at a high speed through a first motor to trim the coating, without the need for drying in the sun, to improve work efficiency. However, there will still be a situation where the device can only cut the synthetic leather during use, and it is not convenient for film covering and forming, which further leads to the problem of reducing the practicability of the coating and forming device.
