Technical Field

[0001] The utility model relates to the technical field of synthetic leather processing, in particular to a PU synthetic leather embossed structure. 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 for it. PU synthetic leather is one of the synthetic leather products. It is usually made of impregnated non-woven fabric as the mesh layer and a microporous polyurethane layer as the grain layer. Both the front and back sides 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, balls, etc.

[0003] The patent publication (publication number CN212477162U) discloses a synthetic leather embossing device, including a device housing, an embossing roller, a conveying platform and an electric telescopic rod.

The interior of the conveyor belt 42 is also provided with two conveyor rollers 46 respectively located on both sides of the support plate 4518. The guide wheels 47 are used to support the conveyor belt 42. The arrangement of the supporting ribs 48 further supports the conveyor belt 42, so that when the conveyor belt 42 is resisted by the guide wheels 47, no large bulge will occur, and no indentation will be caused on the surface of the PU synthetic leather, thereby ensuring the embossing effect.

[0029] Specifically, a movable plate connected to the output end of the cylinder 41 is movably provided at the bottom of the fixed seat 4, and L-shaped connecting rods 43 are provided at both ends of the movable plate. A side plate 44 is fixedly provided at one end of the connecting rod 43 away from the movable plate. Both ends of the side plate 44 are semicircular and the diameter of the semicircle is larger than the conveying roller 46, so that the two side plates 44 can limit the two sides of the conveying belt 42, avoiding the situation that the conveying belt 42 shakes and deviates on both sides.

When the docking shaft 19 and the docking groove 5 inside the docking shaft 2 31 are relative, one end of the docking tooth 15 is directly inserted into the docking groove 5 inside the docking shaft 2 31. At the same time, the rotating ring 14 part is sleeved with the docking shaft 2 31 to realize the connection between the docking shaft 19 and the docking shaft 2 31. The setting of the stabilizing rod 132 ensures the stability of the moving process of the driving rod 131, and at the same time avoids the rotation of the driving rod 131 and the docking sleeve 13. Start the motor 6 to drive the docking shaft 19 to rotate, and the docking shaft 19 can drive the docking shaft 2 31 to rotate through the docking tooth 15, and the docking shaft 2 31 drives the embossing roller 3 to perform the embossing operation.
