[0019] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:
[0020] In the present invention, the first motor 13, the second motor 20, the cylinder 5, the first linear module 10, the second linear module 11, the third linear module 12 and the fourth linear module 19 are all connected to the external electronic control system through wires. The above equipment and connection methods are all existing technologies and will not be described in detail here.
[0021] According to the instruction manual Figure 1-4 It can be seen that when the present invention is in use, first one end of the leather on the feed roller 2 is manually pulled to a pair of bottom plates 9 near the feed roller 2, then the leather is slowly pulled out by the pulling assembly, and the position where the pulling assembly clamps the leather is between the pair of bottom plates 9 near the feed roller 2, then the cylinder 5 provided on the top plate 4 is started, and the telescopic end of the cylinder 5 extends to drive the connected moving plate 6 to move vertically downward, and the moving plate 6 drives the three groups of moving rods 7 provided at the bottom to move vertically downward, and the three groups of moving rods 7 drive the three groups of connected pressure strips 8 to move vertically downward, so that the pressure strips 8 are pressed on the surface of the leather, and a gap is left between the pressure strips 8 and the vertical plate 3 to ensure that the leather is in a stable state. To ensure that the moving parts of the traction assembly can pass through it, the three pressure strips 8 and the three bottom plates 9 cooperate to fix the leather, and then the cutting assembly arranged between the two bottom plates 9 away from the feed roller 2 cuts the leather. Finally, the leather is pulled out by the traction assembly, and the cutting operation is repeated. The utility model pulls the leather out by the traction assembly arranged on the three opposite plates 3, the cylinder 5 drives the three pressure blocks to fix the leather, and then the leather between the pair of bottom plates 9 away from the feed roller 2 is cut by the cutting assembly. The leather cutting and pulling process does not require repeated operation by personnel, the operation is labor-saving, and the cutting efficiency is improved.
[0022] There is a possibility of implementation. When the leather needs to be pulled, first start the two groups of first linear modules 10 set on the three pairs of plates 3, so that the slider of the first linear module 10 moves to between the two pairs of plates 3 close to the feed roller 2. Secondly, start the third linear module 12 set on the slider of the second linear module 11, so that the slider of the third linear module 12 drives the pair of clamping blocks 16 of the clamping assembly to align with the upper and lower sides of the leather. The guide rail of the third linear module 12 is set perpendicular to the guide rails of the first linear module 10 and the second linear module 11. Again, start the second linear module 11, and the guide rail of the second linear module 11 is set on the first linear module 10. On the slider, and the guide rail of the second linear module 11 is perpendicular to the guide rail of the first linear module 10, so that the slider of the second linear module 11 moves toward the edge of the leather until the pair of clamps 16 are moved to the upper and lower sides of the edge of the leather. Finally, the first motor 13 is started, and the output end of the first motor 13 drives the connected forward and reverse screws 15 to rotate, and the forward and reverse screws 15 drive the pair of clamps 16 to move toward each other to clamp and fix the leather. A pair of limit rods 17 arranged between a pair of fixed plates 14 can prevent the pair of clamps 16 from offsetting when moving, and then the leather is pulled out by moving the slider clamping assembly of a pair of first linear modules 10.
[0023] In one possible implementation, a pair of rubber pads 18 are provided on opposite sides of the pair of clamping blocks 16 , and the pair of rubber pads 18 can enhance the clamping and fixing of the leather by the pair of clamping blocks 16 .
[0024] There is a possible implementation, when cutting leather, start the fourth linear module 19, the slider of the fourth linear module 19 drives the second motor 20 to move, and the output end of the second motor 20 drives the cutting blade 21 to rotate to cut the leather.
