[0034] 2. A push block, a stretching seat and a linkage rod are provided. When the plywood completes the clamping of the artificial leather, the lifting plate continues to move downward.

[0049] It also includes: a guide rod 6, fixedly mounted on the lower surface of the top plate 3; a push block 16, elastically and telescopically mounted on the outer side of the lifting plate 5; two sets of clamping assemblies, symmetrically mounted on the front and rear sides of the arch frame 2, and a driving mechanism is arranged between the clamping assemblies and the push block 16 to realize the automatic clamping function of the clamping assemblies; a spraying assembly, arranged on the outer side of the arch frame 2, and the leather surface is sprayed with polishing agent through the drive of the clamping assembly.

[0050] The guide rod 6 is perpendicular to the top plate 3 , and passes through the lifting plate 5 and forms a lifting structure with the lifting plate 5 , and the polishing roller 14 is driven to fit the surface of the artificial leather during the downward movement of the lifting plate 5 .

[0051] The upper end of the push block 16 is fixedly connected to a lifting rod 15, and the lifting rod 15 passes through the lifting plate 5, and a second spring 17 is connected between the lifting plate 5 and the push block 16. The driving mechanism includes a linkage rod 19 arranged below the push block 16, and a roller is rotatably installed on the top of the linkage rod 19, and the clamping assembly includes a stretching seat 18 symmetrically installed on both sides of the arch frame 2. At the same time, the linkage rod 19 and the stretching seat 18 constitute a lifting structure, and the roller on the top of the linkage rod 19 is attached to the inclined surface of the push block 16 during the downward movement.

[0052] The stretching seat 18 and the arch frame 2 are elastically slidably connected, and a clamp 21 is elastically rotatably installed on the stretching seat 18, and a gear 22 is fixedly installed on the shaft of the clamp 21. At the same time, tooth blocks are evenly arranged on the outer side of the lower end of the linkage rod 19, and the linkage rod 19 moves downward and the tooth blocks on its outer side are meshed and connected with the gear 22 to drive the clamp 21 to rotate elastically.

[0053] The clamping assembly also includes a fixing column 20 fixedly mounted on the stretching seat 18, and the clamp 21 is arranged in an arc-shaped structure, and the clamp 21 cooperates with the fixing column 20 to clamp and fix the edge position of the artificial leather during rotation.

[0054] The push block 16 pushes the clamped stretching seat 18 and the clamping plate 23 to slide during the continuous downward movement, and the two stretching seats 18 stretch and flatten the artificial leather during the elastic sliding process.

[0055] The spray assembly includes a clamping plate 23 fixedly installed below the stretching seat 18 and a fixing plate 24 fixedly installed on the upper surface of the cabinet 1, and a liquid capsule 25 is fixedly bonded between the clamping plate 23 and the fixing plate 24, a liquid storage tank 27 is fixedly installed between the cabinet 1 and the arch frame 2, and a spray pipe 26 is fixedly installed above the stretching seat 18, and the spray hole of the spray pipe 26 faces the artificial leather, and a liquid outlet pipe and a liquid inlet pipe are respectively connected between the liquid capsule 25, the spray pipe 26 and the liquid storage tank 27, and both the liquid outlet pipe and the liquid inlet pipe are provided with a one-way valve structure;

[0056] The spray pipe 26 is evenly provided with spray holes, and the openings of the spray holes face the surface of the artificial leather.

[0057] By adopting the above technical solution, when it is necessary to polish the artificial leather, the two ends of the artificial leather are placed above the stretching seat 18, so that the end of the artificial leather is located between the fixed column 20 and the clamping plate 23, and then the electric push rod 4 is controlled to push the lifting plate 5, so that the lifting plate 5 moves down along the guide rod 6. At this time, the lifting plate 5 will drive the push block 16 to move down synchronously through the second spring 17. At this time, the push block 16 will contact and push the linkage rod 19 to move down synchronously and elastically, so that the tooth block and the gear 22 at the lower end of the linkage rod 19 are meshed and connected, thereby driving the clamping plate 23 to rotate elastically, and the water-piercing clamping plate 23 will fold and bend the edge of the artificial leather, thereby cooperating with the fixed column 20 to automatically clamp and fix the artificial leather. After the artificial leather is fixed, the lifting plate 5 is continued to be controlled to move down, so that the roller at the top of the linkage rod 19 moves along the inclined direction of the push block 16. The surface rolls, so that the linkage rod 19 can push the stretching seat 18 to slide along the surface of the arch frame 2. At this time, the two stretching seats 18 can automatically stretch and flatten the artificial leather, and when the stretching seat 18 cannot move, the lifting rod 15 and the lifting plate 5 can be elastically retracted, thereby avoiding jamming when the lifting plate 5 continues to move downward, and when the stretching seat 18 moves and stretches the artificial leather, the clamping plate 23 at the lower end of the stretching seat 18 will cooperate with the fixing plate 24 to squeeze the liquid capsule 25, so that the liquid capsule 25 can evenly spray the polishing agent inside it to the surface of the artificial leather through the spray pipe 26, which is convenient for subsequent polishing treatment, and when the polishing is completed, the liquid capsule 25 can be stretched by the clamping plate 23 during the resetting process of the stretching seat 18, so that the liquid capsule 25 can extract the polishing agent in the liquid storage tank 27 through the pipeline, which is convenient for subsequent reuse.

[0058] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. The polishing direction of the existing polishing machine for artificial leather processing is single, which makes its polishing efficiency limited, and the artificial leather is prone to wrinkles during the polishing process. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1-Figure 4 and Figure 8 As shown;

[0061] By adopting the above technical solution, when the artificial leather is fixed, the motor 7 is started to drive the threaded rod 8, and the threaded rod 8 drives the movable seat 9 to move back and forth through the threaded connection. At this time, the polishing roller 14 can rub and polish the surface of the artificial leather, and as the movable seat 9 moves, the top of the telescopic rod 10 arranged thereon will slide against the inclined surface of the resistance block 501, so that the telescopic rod 10 drives the adjustment plate 12 to reciprocate and rise and fall under the elastic force of the first spring 11, and the movable frame 13 under the adjustment plate 12 can be elastic, so that the polishing roller 14 can automatically polish the surface of the artificial leather in multiple directions, effectively improving the polishing efficiency.
