Description

Technical Field

[0001] This utility model relates to the field of leather cutting technology, specifically a multi-layer cutting machine. Background Technology

[0002] In the production process of leather products, the leather needs to be cut into the required size to meet the usage requirements, so a cutting knife is needed to cut the leather.

[0003] When cutting leather, most processes can only handle a single piece of leather. Cutting a single piece is time-consuming and laborious, reducing cutting efficiency. Furthermore, when cutting multiple pieces of leather simultaneously, the blade must penetrate all layers, increasing the load by 3-5 times. Data from a material factory shows that the lifespan of the blade drops drastically from 5,000 cuts per layer to 800 cuts per layer. If the blade cannot be replaced quickly and promptly, it will not only affect work efficiency but also subsequent production. Utility Model Content

[0006] The multi-layer limiting assembly includes a vertical plate slidably disposed on the upper surface of the base. A square groove is formed on one side of the vertical plate, and a double-ended lead screw is rotatably disposed on the inner surface of the square groove. A square plate is threaded onto the outer surface of the double-ended lead screw, and the square plate slides in contact with the inner surface of the square groove. A round block is fixed between the double-ended lead screws. A drive motor is fixedly disposed on the upper surface of the vertical plate, and the output end of the drive motor is fixedly connected to the upper end of one of the double-ended lead screws. A limiting plate is fixedly disposed on one side of the square plate, and a rubber block is fixedly disposed on the opposite side of the limiting plate. A horizontal plate is fixedly disposed on one side of the base, and a rectangular groove is formed on the horizontal plate. A rectangular rod is slidably disposed in the rectangular groove, and the other end of the rectangular rod is fixedly connected to the vertical plate. Limiting holes are formed on both the horizontal plate and the rectangular rod, and a limiting rod is movably inserted into the limiting holes.

[0007] Preferably, the end of the connecting rod is provided with a positioning groove, and a positioning block is fixedly provided on one side of the cutting disc. The positioning block is movably inserted into the positioning groove. Both the positioning block and the connecting rod are provided with through holes. An assembly bolt is movably inserted into the through hole, and a nut is threaded on the outer surface of the assembly bolt.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

Several limiting holes 63 are provided, and the limiting holes 63 are arrayed on the upper surface of the horizontal plate 6 to facilitate limiting after adjustment. Multiple pieces of leather to be cut can be placed between two corresponding limiting plates 76. Then, by starting the drive motor 75, the uppermost double-headed screw 73 can be rotated. The double-headed screw 73 can drive the other two double-headed screws 73 to rotate through the round block 78, so that the limiting plates 76 can move in opposite directions to clamp and limit the leather, which is convenient for limiting multiple pieces of leather.

[0021] An electric slide rail 5 is fixedly provided on the upper surface of the bracket 2. An electric slider 51 is slidably provided inside the electric slide rail 5. A connecting plate 52 is fixedly provided on the electric slider 51.

[0022] A horizontal plate 6 is fixedly provided on one side of the base 1. A rectangular groove 61 is provided on the horizontal plate 6. A rectangular rod 62 is slidably provided in the rectangular groove 61. The other end of the rectangular rod 62 is fixedly connected to a vertical plate 71. Limiting holes 63 are provided on both the horizontal plate 6 and the rectangular rod 62. A limiting rod 64 is movably inserted into the limiting hole 63 to facilitate the adjustment of the position of the two vertical plates 71. The vertical plates 71 can be moved first according to the size of the leather to be cut. The limiting rod 64 is pulled out from the limiting hole 63 to release the limitation. Then the vertical plates 71 can be moved to adjust the distance between the vertical plates 71. After adjusting to a suitable position, the limiting rod 64 is inserted into the corresponding limiting hole 63 provided on the horizontal plate 6 and the rectangular rod 62.

[0023] The rubber blocks 77 are provided in a plurality of arrays and distributed on one side of the limiting plate 76. The stability of the leather limiting can be improved by multiple rubber blocks 77. The upper surface of the base 1 is provided with a vertical groove 8, and the output end of the electric telescopic rod 23 will not contact the base 1 at the end point.

[0024] The end of the connecting rod 26 is provided with a positioning groove 33. A positioning block 31 is fixedly provided on one side of the cutting disc 4. The positioning block 31 is movably inserted into the positioning groove 33. Both the positioning block 31 and the connecting rod 26 are provided with through holes 32. An assembly bolt 34 is movably inserted into the through hole 32. A nut 35 is threaded on the outer surface of the assembly bolt 34. When the cutting disc 4 needs to be replaced, the nut 35 is rotated to disengage it from the assembly bolt 34. Then the assembly bolt 34 can be pulled out from the through hole 32 to release the restriction. Subsequently, the cutting disc 4 can be moved to the side. Then the positioning block 31 on the new cutting disc 4 can be inserted into the positioning groove 33 and assembled with the assembly bolt 34 and nut 35 to facilitate the replacement of the new cutting disc 4.

[0025] Working principle: When using this utility model, the vertical plate 71 can be moved first according to the size of the leather to be cut. The limiting rod 64 is pulled out from the limiting hole 63 to release the limitation. Then the vertical plate 71 can be moved to adjust the distance between the vertical plates 71. After adjusting to a suitable position, the limiting rod 64 is inserted into the corresponding limiting hole 63 opened on the horizontal plate 6 and the rectangular rod 62.

[0026] Multiple leathers that need to be cut can be placed between two corresponding limiting plates 76. Then, by starting the drive motor 75, the uppermost double-headed screw 73 can be rotated. The double-headed screw 73 can drive the other two double-headed screws 73 to rotate through the round block 78, thereby allowing the limiting plates 76 to move in opposite directions to clamp and limit the leather, which is convenient for limiting multiple leathers.

[0027] The first motor 25 can be started to rotate the connecting rod 26 at its end, thereby driving the cutting disc 4 installed at its output end to rotate. The cutting disc 4 can be moved downward by starting the electric telescopic rod 23. The electric slider 51 inside the electric slide rail can be moved by starting the electric slide rail 5. The cutting disc 4 can be moved to the side by the connecting plate 52, so that multiple leathers can be cut at the same time.

[0028] When the cutting disc 4 needs to be replaced, the nut 35 is rotated to disengage it from the assembly bolt 34. Then the assembly bolt 34 can be pulled out from the through hole 32 to release the limit. The cutting disc 4 can then be moved to the side. After that, the positioning block 31 on the new cutting disc 4 can be inserted into the positioning groove 33 and assembled with the assembly bolt 34 and nut 35 to facilitate the replacement of the new cutting disc 4.
