[0020] Please refer to Figures 1-4 , wherein Figure 1 is a schematic structural view of a leather cutting device provided by the present utility model; Figure 2 is Figure 1 a sectional view of a leather cutting device shown in Figure 3 is Figure 2 a schematic structural view of the moving frame and the cutting device shown in Figure 4 is Figure 2 a schematic structural view of the comparison plate shown in
[0021] In the specific implementation process, as Figures 1-4 shown, a leather cutting device includes a base 1, a moving frame 5, a cutting device and a moving device. The cutting device is arranged in the moving frame 5. The moving frame 5 is slidably connected to the base 1. The moving device is fixedly installed on one side of the base 1;
[0022] Both sides of the base 1 are provided with sliding grooves 2. Both sides of the moving frame 5 are fixedly connected with sliders 7. The sliders 7 can slide in the sliding grooves 2. Scale lines 20 are marked above the sliding grooves 2 on both sides of the base 1. The starting position of the scale lines 20 is set at one end away from the winding roller 11, and the starting scale value of the scale lines 20 is the linear distance value between the bottom end of the cutting knife 16 and the inner side of the comparison plate 6. Therefore, when the moving frame 5 moves, the distance between the cutting knife 16 and the comparison plate 6 can be ignored, and it can be directly moved to the target length. The moving device includes a mounting plate 8. The mounting plate 8 is fixedly connected to the top of one end of the base 1. A driving member 9 is fixedly connected to the top of the mounting plate 8. The telescopic end of the driving member 9 is fixedly connected with a connecting rod 14. The other end of the connecting rod 14 is fixedly connected with one side of the moving frame 5. The other side of the moving frame 5 is fixedly connected with a comparison plate 6. The comparison plate 6 is slidably connected to both sides of the base 1. An electric telescopic rod 17 is fixedly connected to the bottom of the comparison plate 6. A pressing plate 18 is fixedly connected to the bottom of the electric telescopic rod 17. When the driving member 9 is started, the telescopic end of the driving member 9 can drive the connecting rod 14, the moving frame 5 and the comparison plate 6 to move. The slider 7 moves in the sliding groove 2. When the moving frame 5 moves, observe the scale lines 20 on both sides of the inner side of the comparison plate 6 and the top end of the base 1, and directly move to the target length. Start the electric telescopic rod 17, and the electric telescopic rod 17 drives the pressing plate 18 to move downward until the leather 10 is pressed. The model of the electric telescopic rod 17 is: KM01.
[0023] The driving member 9 is a multi-stage electric cylinder. The multi-stage electric cylinder has a compact structure, a small installation space and strong adaptability. The multi-stage electric cylinder can complete telescopic movement through the combination of multiple cylinders and lead screws. The model of the multi-stage electric cylinder is: LMC3D220.
[0024] A bump 19 is fixedly connected to the bottom of the pressing plate 18. The bump 19 is made of silica gel, and the silica gel bump 19 increases the friction between the pressing plate 18 and the leather 10.
[0025] A telescopic electric cylinder 4 is fixedly connected to the top end of the moving frame 5. The telescopic end of the telescopic electric cylinder 4 extends into the moving frame 5. The cutting device includes a connecting plate 15 and a cutter 16. The top of the connecting plate 15 is fixedly connected to the telescopic end of the telescopic electric cylinder 4, and the bottom of the connecting plate 15 is fixedly connected to the cutter 16. When the telescopic electric cylinder 4 is started, the telescopic end of the telescopic electric cylinder 4 can drive the connecting plate 15 and the cutter 16 to move downwards, and then the leather 10 can be cut.
[0026] One side of the base 1 close to the mounting plate 8 is fixedly connected with a bottom plate 13. Two sides of the bottom plate 13 are fixedly provided with brackets 12. A winding roller 11 is rotatably connected to the brackets 12. The leather 10 is wound around the winding roller 11, and the leather 10 can pass through between the mounting plate 8 and the base 1 to the top end of the base 1.
[0027] A blocking plate 3 is fixedly connected to one end of the base 1 away from the mounting plate 8 to prevent the leather 10 from extending out of the base 1, resulting in inaccurate cutting length.
[0028] The working principle provided by the present utility model is as follows: In the existing leather cutting device, during specific implementation, the leather 10 is wound around the winding roller 11. The leather 10 is pulled through between the mounting plate 8 and the base 1 and pulled to the blocking plate 3 at the other end of the base 1. The multi-section electric cylinder is started, and the telescopic end of the multi-section electric cylinder drives the connecting rod 14, the moving frame 5 and the comparison plate 6 to move. The slider 7 moves in the chute 2. When the moving frame 5 moves, observe the scale lines 20 on both sides of the inner side of the comparison plate 6 and the top end of the base 1. Since the starting scale value of the scale line 20 is the linear distance value between the bottom end of the cutter 16 and the inner side of the comparison plate 6, the distance between the cutter 16 and the comparison plate 6 can be ignored, and it can be directly moved to the target length. Then the electric telescopic rod 17 is started, and the electric telescopic rod 17 drives the pressing plate 18 to move downwards until the leather 10 is pressed. The silica gel bump 19 at the bottom of the pressing plate 18 increases the friction between the pressing plate 18 and the leather 10. Then the telescopic electric cylinder 4 is started, and the telescopic end of the telescopic electric cylinder 4 drives the connecting plate 15 and the cutter 16 to move downwards, and then the leather 10 can be cut.
[0029] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here.
[0030] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
