[0044] When in use, the operating table 1 supports the transmission module 2, the operating table 1 supports the conveying platform 3, the motor of the transmission module 2 is started, the output shaft of the motor starts to rotate forward, the output shaft of the motor drives the belt of the pulley group to rotate forward, the pulley group drives the long axis of the conveying platform 3 to rotate forward, the long axis drives the conveyor belt to rotate forward, the staff puts the leather material on the conveyor belt of the conveying platform 3, the conveyor belt carries the leather material to move to the right, because the surface of the leather material will be wrinkled during the marking process of the marking equipment, which may cause the marking machine to be difficult to laser etch the surface of the leather material At this moment, when the conveyor belt of the conveyor table 3 carries the leather material and moves to the bottom of the laser head of the marker 412, the motor output shaft of the transmission module 2 stops rotating, the operating table 1 supports the U-shaped frame 4, the electric telescopic rod 411 on the U-shaped frame 4 is started, the telescopic end of the electric telescopic rod 411 starts to move downward, the telescopic end of the electric telescopic rod 411 drives the marker 412 to move downward, the marker 412 moves downward in the slide groove of the U-shaped frame 4, the marker 412 drives the U-shaped short frame 413 to move downward, and the U-shaped short frame 413 drives the rotating shaft 414 to move downward. The rotating shaft 414 drives the inclined plate 415 to move downward, and the inclined plate 415 drives the round roller 416 to move downward. At the same time, the rotating shaft 414 drives the arc elastic strip 417 to move downward. In the process of the round roller 416 moving downward, the round roller 416 contacts the surface of the leather material. Under the action of the extrusion force, the round roller 416 rolls on the surface of the leather material. The rotating shaft 414 rotates in the U-shaped short frame 413, and the rotating shaft 414 drives the inclined plate 415 to rotate. The arc elastic strip 417 on the rotating shaft 414 is deformed.

When the round roller 416 stretches the surface of the leather material to make it flat, the marker 412 is started, and the laser of the marker 412 marks the surface of the leather material. When the marking is completed, the telescopic end of the electric telescopic rod 411 is reset, and the round roller 416 is reset under the elastic force of the arc elastic strip 417.

[0045] When the marker 412 moves downward in the slide groove of the U-shaped frame 4, the marker 412 drives the orifice plate 421 to move downward, the L-shaped plate 423 supports the thin rod 422, and the orifice plate 421 slides downward on the outer wall of the thin rod 422.

The top surface of the belt of the conveyor platform 3 is on the movement trajectory of the four abutment plates 54. When the abutment plates 54 move downward, the abutment plates 54 contact the conveyor belt of the conveyor platform 3. Under the extrusion of the round roller 416, the conveyor belt will be concavely arc-shaped, so that the abutment plates 54 flatten the concave parts of the conveyor belt to avoid the conveyor belt being concavely arc-shaped when the laser marking machine is in use, causing the leather material surface to be uneven.

The inner walls of the four U-shaped rubber sleeves 57 are located on the movement trajectories of the four inclined plates 415. When the round roller 416 moves downward, the inclined plate 415 contacts the U-shaped rubber sleeves 57. The U-shaped rubber sleeves 57 limit the inclined plate 415 so that the round roller 416 on the inclined plate 415 will not excessively pull the leather material, thereby avoiding excessive pulling of the leather material and causing damage to the leather material when the laser marking machine is in use.

In the process of the square plates 67 moving downward, the square plates 67 are in contact with the conveyor belt. Under the action of the extrusion force, the square plates 67 flatten the edge of the conveyor belt to make the leather material on the conveyor belt smoother, so as to avoid the uneven edge of the leather material when the laser marking machine is in use, resulting in poor laser etching effect on the edge of the marking machine.

In the process of the round roller 416 moving downward, the inclined plate 415 contacts the U-shaped rubber sleeve 57, so that the U-shaped rubber sleeve 57 limits the inclined plate 415, so that the round roller 416 on the inclined plate 415 will not excessively pull the leather material, thereby preventing the device from excessively pulling the leather material when in use, thereby avoiding the problem of excessive pulling of the leather material causing damage to the leather material when the laser marking machine is in use.

[0061] When the rectangular plate 53 drives the support plate 54 to move downward, the support plate 54 drives the U-shaped rod 61 to move downward, the U-shaped rod 61 drives the cross plate 62 to move downward, and the cross plate 62 drives the inclined box 63 to move downward. At the same time, the inclined plate 415 drives the slide bar 64 to move, and the slide bar 64 slides in the inclined box 63, so that the inclined box 63 limits the slide bar 64, and the slide bar 64 limits the inclined plate 415, so that the round roller 416 on the inclined plate 415 will not shake violently when leveling the leather material, and the round roller 416 on the inclined plate 415 can level the leather material more stably, thereby avoiding the problem of poor leveling effect of the leather material caused by the unstable leveling of the leather material by the round roller 416 when the laser marking machine is in use.

[0062] While the abutment plate 54 drives the U-shaped rod 61 to move downward, the U-shaped rod 61 drives the ring block 65 to move downward, the ring block 65 drives the short rod 66 to move downward, and the short rod 66 drives the square plate 67 to move downward. In the process of the square plate 67 moving downward, the square plate 67 contacts the conveyor belt. Under the action of the extrusion force, the square plate 67 flattens the edge of the conveyor belt to make the leather material on the conveyor belt smoother, preventing the edge of the leather material from being uneven when the equipment is in use, thereby avoiding the problem of poor laser etching effect on the edge of the marking machine caused by the uneven edge of the leather material when the laser marking machine is in use.
