[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] As attached Figure 1 As shown, an adjustable cutting device for synthetic leather includes a mounting plate 1, a cutting blade 8, and a worktable 19. An electric telescopic rod 20 is installed on one side of the worktable 19, and a connecting shaft 21 is installed at the upper end of the electric telescopic rod 20. A connecting ring 18 is installed on one side of the mounting plate 1. The connecting ring 18 is a clamp and is fixedly sleeved on the outside of the connecting shaft 21 and fixed with bolts. The height of the cutting device can be adjusted by moving the mounting plate 1 up and down through the electric telescopic rod 20.

[0029] As attached Figure 2 Appendix Figure 3 and attached Figure 5 As shown, an adjustment plate 2 is provided on the lower side of the mounting plate 1, and a motor 3 is installed on the upper side of the mounting plate 1. The shaft end of the motor 3 is connected to the middle of the upper side of the adjustment plate 2. A positioning plate 12 slides through the side of the adjustment plate 2. An electromagnet plate 15 is installed on one side of the mounting plate 1. The positioning plate 12 is made of ferrous metal and is attracted and connected to the electromagnet plate 15 to facilitate the positioning of the adjustment plate 2. The adjustment plate 2 is provided with a strip-shaped through hole 11 that cooperates with the positioning plate 12. A limiting plate 13 and a limiting plate 2 14 are respectively installed on the upper and lower sides of the positioning plate 12. The positioning plate 12 is slidably limited and installed inside the strip-shaped through hole 11 by the limiting plate 13 and the limiting plate 2 14.

[0030] As attached Figure 3 and attached Figure 4 As shown, the cutting blade 8 is installed on the lower side of the adjusting plate 2. An adjusting assembly is installed on the lower side of the adjusting plate 2. The adjusting assembly includes two sets of positioning blocks 4, a threaded shaft 5, a second motor 6, and a moving block 7. The two sets of positioning blocks 4 are fixedly installed on the lower two sides of the adjusting plate 2. The threaded shaft 5 is rotatably installed between the two sets of positioning blocks 4. The second motor 6 is installed on one side of the positioning block 4 and drives the threaded shaft 5 to rotate. The moving block 7 is threadedly sleeved on the upper side of the threaded shaft 5. The cutting blade 8 is installed on the lower side of the moving block 7. A limiting slider 9 is installed on the upper side of the moving block 7. The lower side of the adjusting plate 2 is provided with a sliding groove 10 that cooperates with the sliding of the limiting slider 9. By sliding the limiting slider 9 inside the sliding groove 10, the moving block 7 is limited to prevent the moving block 7 from rotating with the threaded shaft 5.

[0031] As attached Figure 2 As shown, a control switch 16 connected to motor 3 and motor 6 is installed on the upper side of the mounting plate 1.

[0032] As attached Figure 1 and attached Figure 2 As shown, the cutting blade 8 is a strip-shaped cutting blade with multiple cutting edges on each side, which facilitates adjustment of the cutting direction. The adjustment plate 2 has a scale line 17 on its side, with the zero point of the scale line 17 at the center of the adjustment plate 2, which makes it easy to check the movement position of the cutting blade 8 and control the circular cutting size. The upper side of the worktable 19 is equipped with a combination knife groove 22 that cooperates with the rotation and transverse cutting of the cutting blade 8. The combination knife groove 22 includes multiple sets of annular knife grooves corresponding to commonly used circular fabric sizes and a set of transverse cutting knife grooves. The multiple sets of annular knife grooves are nested at the same center, and the center corresponds to the zero point of the scale line 17. The size of the combination knife groove 22 can be set to various values. By changing the worktable 19, circular fabrics of each size can be produced.

[0033] The specific usage method is as follows:

[0034] Place the synthetic leather on the workbench 19 and position it using an external positioning component. Select circular cutting or transverse cutting based on the fabric production shape.

[0035] During circular cutting, the electromagnet plate 15 loses its attraction force by controlling switch 16, and the positioning plate 12 moves downward. The limiting plate 13 is supported on the upper side of the adjusting plate 2. The position of the cutting blade 8 is adjusted according to the size of the circular fabric. The initial position of the cutting blade 8 corresponds to the zero point of the scale line 17 and the center of the annular cutting groove, and the cutting blade 8 is located directly above the horizontal cutting groove. The motor 6 is started by controlling switch 16, which drives the threaded shaft 5 to rotate. The threaded shaft 5 drives the moving block 7 to move horizontally. The position of the cutting blade 8 is adjusted in conjunction with the scale line 17. After the position of the cutting blade 8 is determined, the electric telescopic rod 20 retracts, which drives the cutting blade 8 to move down and insert into the corresponding circular cutting groove in the combined cutting groove 22. The motor 3 is started by controlling switch 16, which drives the adjusting plate 2 to rotate 360° to cut the circular fabric.

[0036] During transverse cutting, the positioning plate 12 is moved upward, and the electromagnet plate 15 is attracted by the control switch 16, so that the positioning plate 12 is attracted to the electromagnet plate 15. At this time, the cutting blade 8 is located directly above the transverse cutting groove in the combined cutting groove 22. The electric telescopic rod 20 retracts, driving the cutting blade 8 to move downward and insert into the corresponding transverse cutting groove in the combined cutting groove 22. The motor 6 is started by the control switch 16, and the rotating threaded shaft 5 drives the moving block 7 and the cutting blade 8 to move along the length of the transverse cutting groove to perform transverse cutting on the fabric.
