Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 2 , Figure 4The utility model provides an embodiment: a sofa leather cutting machine, comprising a base 1, the top of the base 1 is fixedly connected to a mounting frame 2, the top of the mounting frame 2 is provided with two slide grooves 28, the inside of the front slide groove 28 is rotatably connected with a threaded rod 8, the outer side of the threaded rod 8 is threadedly connected with a threaded block 7, the bottom end of the threaded block 7 is fixedly connected to a fixed plate 17, the top middle end of the mounting frame 2 is slidably connected with a slide plate 10, the top of the slide plate 10 is fixedly connected with an air pump 3, the output end of the air pump 3 is fixedly connected with a connecting plate 18, the bottom end of the connecting plate 18 is fixedly connected with a mounting block 19, the inner and outer parts of the mounting block 19 are slidably connected with a connecting shell 20, the outer part of the connecting shell 20 A tool 21 is fixedly connected, two slide grooves 27 are provided on the outer side of the connecting shell 20, mounting grooves 23 are provided on the left and right sides of the inside of the mounting block 19, the inside of the mounting groove 23 is slidably connected to a movable plate 25, one side of the movable plate 25 is fixedly connected to a clamping block 26, the other side of the movable plate 25 is fixedly connected to a connecting rod 22, the outer side of the connecting rod 22 is sleeved with a spring 24, the outer surface of the mounting frame 2 is fixedly connected to a motor 4, the output end of the motor 4 is fixedly connected to one end of the threaded rod 8, one end of the spring 24 is connected to the inner wall of the mounting groove 23, the other end of the spring 24 is fixedly connected to the outside of the movable plate 25, and the bottom end of the base 1 is fixedly connected to two pressing components.
[0031] Specifically, by turning on the motor 4, the motor 4 drives the threaded rod 8 to rotate, so that the threaded block 7 rotates, and the slide plate 10 also moves accordingly, so that the air pump 3 moves left and right, and then the air pump 3 is started, and the air pump 3 drives the tool 21 to press downward to cut the leather. When the tool 21 is damaged and the tool 21 is replaced, the connecting rod 22 is pulled by external force. Under the action of external force, the movable plate 25 will move outward along the inner wall of the mounting groove 23, so that the spring 24 is in a compressed state, and the spring 24 moves outward on the inner wall of the mounting groove 23. When the spring 24 moves outward, the block 26 also moves outward. At this time, the tool 21 is replaced and the tool 21 is placed in the connecting shell 20. By loosening the connecting rod 22, under the action of the spring 24, the movable plate 25 is reset, and the block 26 is stuck in the slide groove 27, so that the tool 21 is replaced. The air pump 3, the threaded rod 8, and the slide block 6 are the existing structures, which makes this device more perfect when working.
[0032] Reference Figure 1 , Figure 3 The pressing assembly includes two mounting shells 5, the outer surfaces of the mounting shells 5 are respectively fixed on the left and right sides of the base 1, the interior of the mounting shells 5 is rotatably connected with a bidirectional screw 15, the outer surface of the bidirectional screw 15 is threadedly connected with two threaded sleeves 11, the bottom end of the threaded sleeve 11 is rotatably connected with a sliding frame 13, and the bottom end of the sliding frame 13 is rotatably connected with a rubber plate 14.
[0033] Specifically, by starting the motor 2 16, when the motor 2 16 is started, the bidirectional screw 15 rotates inside the mounting shell 5, thereby driving the two threaded sleeves 11 to move left and right at the same time, thereby driving the sliding frame 13 to move, and the sliding frame 13 drives the rubber plate 14 to press the leather, and the telescopic rod 12 plays an auxiliary role, so that the leather can be fixed to improve cutting accuracy, improve production efficiency, reduce costs, reduce waste, and improve product quality.

[0035] Specifically, by installing a fixing rod 9 inside the rear side slide groove 28 of the mounting frame (2), installing a slider 6 on the outside of the fixing rod 9, and installing the slider 6 on the top of the fixing plate 17, the air pump 3 is more stable during movement, thereby making the leather cutting more accurate.
[0036] Reference Figure 2 The cross section of the threaded block 7 is set to be square, and the outer surface of the threaded block 7 is in contact with the inner wall of the second slide groove 28.
[0037] Specifically, by setting the cross section of the threaded block 7 to be square, it can better fit with the inner wall of the second slide groove 28, so that it is stable during movement.
[0038] Reference Figure 4 The shape of the block 26 matches the slide slot 1 27 , and the block 26 and the slide slot 1 27 are plugged into each other.
[0039] Specifically, by setting the shape of the clamping block 26 to match the shape of the sliding groove 27 , the clamping block 26 and the sliding groove 27 are more compatible, thereby stabilizing the tool 21 .
[0040] Reference Figure 3 The top of the rubber plate 14 is fixedly connected to two telescopic rods 12, the top of the telescopic rods 12 is fixedly connected to the bottom of the mounting shell 5, and one side of the mounting shell 5 is fixedly connected to a motor 2 16.
[0041] Specifically, two telescopic rods 12 are installed at the bottom end of the mounting shell 5, and a second motor 16 is installed on the outer side of the mounting shell 5, so that the telescopic rods 12 assist in pressing the leather to make it more firm.
[0042] Working principle: When using this product, first put the leather on the top of the base 1, start the motor 4, and drive the bidirectional screw 15 inside the mounting shell 5 to rotate under the drive of the motor 4. At this time, the two threaded sleeves 11 will approach each other along the outer wall of the bidirectional screw 15, thereby driving the top of the sliding frame 13 to swing. At this time, under the traction of the sliding frame 13, the rubber plate 14 is driven to press downward, and the telescopic rod 12 performs auxiliary pressing to make it more firm, ensuring that the position of the leather will not change during the shearing process, so as to ensure that the leather is firmly fixed on the workbench during the cutting process, thereby improving the cutting accuracy, quality and safety; then start the air pump 3 and press downward. Under the pressure, the cutter 21 cuts the leather. When the cutter 21 is damaged and the cutter 21 is replaced, the connecting rod 22 is pulled by external force. Under the action of external force, the movable plate 25 moves outward along the inner wall of the mounting groove 23, and the spring 24 is compressed. The spring 24 moves outward on the inner wall of the mounting groove 23. When the spring 24 moves outward, the block 26 also moves outward. At this time, the cutter 21 is replaced and the cutter 21 is placed in the connecting shell 20. By loosening the connecting rod 22, the movable plate 25 is reset under the action of the spring 24, and the block 26 is stuck in the slide groove 27, so that the cutter 21 is replaced. The method is simple and fast, and it is convenient for people to use.
[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
