[0028] The bottom of lower plate 7 is provided with hidden groove communicated with sliding slot, and guide rail 702 is fixedly connected in hidden groove, and electric pulley 703 is arranged on guide rail 702 (electric pulley 703 can drive L-shaped slide bar 9 and rectangular cutting knife 10 to move by connecting shaft 901, so that the position of rectangular cutting knife 10 is changed, and the distance of rectangular cutting knife 10 is moved each time is same), and connecting shaft 901 is rotatably connected between two L-shaped slide bars 9 and electric pulley 703.

[0029] The top of base 1 is fixedly connected with U-shaped cutting table 2, the top of U-shaped cutting table 2 is provided with discharge chute (the cloth punched and cut falls into material collecting box 102 through discharge chute), and mounting shaft is fixedly connected in discharge chute, and rotating plate 201 is rotatably connected on the surface of mounting shaft (cloth is punched and cut at rotating plate 201), and the two side walls of U-shaped mounting bracket 6 are provided with oppositely arranged sliding slot, and the two ends of lower plate 7 are fixedly connected with sliding block 701 slidably connected with sliding slot.

[0030] Further, one end of lower plate 7 is provided with oppositely arranged through hole, and stand 802 is slidably connected in through hole, and limit disc 8 is fixedly connected at the two ends of stand 802, and limit spring 801 is fixedly connected between the top of lower plate 7 and one of limit disc 8 (cloth is pressed and positioned by limit spring 801 and limit disc 8, to avoid that cloth is deviated when punching).

[0031] It needs to be explained that: one end of the U-shaped mounting frame 6 is fixedly connected with the relatively arranged slide rails 3, a cloth pushing assembly is arranged between the two slide rails 3, the cloth pushing assembly comprises a driving wheel 301 located in the slide rail 3, the top of the base 1 is provided with a U-shaped moving plate 4, both ends of the U-shaped moving plate 4 are rotatably connected with the driving wheel 301 through a driving shaft, the bottom end of the U-shaped moving plate 4 is fixedly connected with the relatively arranged extrusion springs 401, one end of the extrusion spring 401 is fixedly connected with an extrusion plate 5 (the driving wheel 301 drives the cloth to move to the rectangular cutting knife 10 through the U-shaped moving plate 4 and the extrusion plate 5, which facilitates cutting).

[0032] It is worth noting that: the top of the base 1 is placed with a material collecting box 102 located below the rotating plate 201 (the material collecting box 102 collects the cut cloth), the top of the base 1 is fixedly connected with the relatively arranged electric push rods 101 which are in contact with the bottom end of the rotating plate 201, and the top of the base 1 is placed with a waste collecting box 103 (the waste collecting box 103 collects the waste cloth after cutting).

[0033] The above further benefits are: the above device controls the distance of the cutting knife to move each time through the electrical equipment, which avoids the waste of cloth caused by the inclination of the cutting knife to the greatest extent, and avoids the contact between the cutting knife and the previously cut part on the cloth when the cutting knife is placed, thereby ensuring the legal requirements of the punched and cut cloth, saving time and labor while improving the output of cloth cutting.

[0034] When the cloth needs to be cut on the cloth, the staff moves the extrusion plate 5 to place the cloth on the base 1, presses the tail end of the cloth by the extrusion spring 401 and the extrusion plate 5, then the staff starts the driving wheel 301, so that the driving wheel 301 moves along the slide rail 3 and drives the U-shaped moving plate 4 and the extrusion plate 5 to move, thereby pulling the cloth to move, so that the front end of the cloth moves to the rotating plate 201, then the staff closes the driving wheel 301 and starts the hydraulic cylinder 601;

[0035] The hydraulic cylinder 601 drives the lower plate 7 and the two rectangular cutting knives 10 to move downward, when the lower plate 7 moves downward to the limit disc 8 and contacts the cloth, the limit spring 801 and the limit disc 8 press and fix the cloth, then the lower plate 7 and the rectangular cutting knife 10 continue to move downward to cut the cloth, and the cloth is punched and cut to have the same shape as the rectangular cutting knife 10;

[0036] Then the hydraulic cylinder 601 drives the lower plate 7 and the rectangular cutter 10 to move up by a distance, at this time the worker starts the electric pulley 703, the electric pulley 703 drives the two rectangular cutters 10 to move through the connecting shaft 901 and the L-shaped slide rod 9, and moves a certain distance, then the hydraulic cylinder 601 continues to drive the lower plate 7 and the rectangular cutter 10 to cut the cloth, the electric pulley 703 drives the rectangular cutter 10 to move intermittently horizontally along the guide rail 702, and the cloth is cut;

[0037] When the cloth on the rotating plate 201 is cut, the electric push rod 101 is controlled to retract, at this time the rotating plate 201 rotates under the action of its own gravity, so that the cut cloth on the cloth falls into the material collecting box 102, then the electric push rod 101 is controlled to reset and push the rotating plate 201 to the original position, then the worker controls the driving wheel 301 to continue to move and push the cloth forward, so that the part to be cut on the cloth is located on the rotating plate 201, facilitating subsequent cutting of the cloth;

[0038] When the cloth is completely cut, the waste cloth falls into the waste collecting box 103, the above device controls the cutter to move the same distance each time through electrical equipment, which avoids the waste of cloth caused by the inclination of the cutter to the greatest extent, and avoids the contact between the cutter and the previously cut part on the cloth when the cutter is placed, so as to ensure that the punched and cut cloth meets the legal requirements, saves time and labor, and improves the output of cloth cutting.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
