[0026] Reference Figures 1 to 5An automatic cloth cutting device shown in the figure includes a base plate 1, which is used to support a fixed conveying component 2 and a cutting component 3, and also includes a fixed conveying component 2 and a cutting component 3. The fixed conveying component 2 is installed on the base plate 1, and the fixed conveying component 2 is used to fix and stably convey the cloth. The cutting component 3 includes a first U-shaped pad 30, a support frame 31, a partition 32, a plurality of cutter heads 33, a plurality of hydraulic rods 34 and a plurality of first springs 35. The bottom of the first U-shaped pad 30 and the bottom of the support frame 31 are both fixedly connected to the top of the base plate 1. The first U-shaped pad 30 is located between the inner walls at both ends of the support frame 31. The first U-shaped pad 30 is used to support the cutting part of the cloth to prevent the cutting from being offset. The support frame 31 is used to support the plurality of cutter heads 33. Both ends of the partition 32 are fixedly connected to the inner wall of the support frame 31, and multiple cutter heads 33 are arranged at intervals in a straight line at the top of the partition 32. The cutter heads 33 pass through the partition 32 and the top wall of the first U-shaped pad 30 and are slidably connected thereto. The top of the hydraulic rod 34 is fixedly connected to the top wall of the support frame 31, and the telescopic end of the hydraulic rod 34 is fixedly connected to the top of the cutter head 33. The first spring 35 is installed on the cutter head 33, and the first spring 35 is used to provide a vertical upward thrust to the cutter head 33. When cutting the cloth, the cloth is passed between the support frame 31 and the first U-shaped pad 30. Since the spacing between the multiple cutter heads 33 is fixed, the hydraulic rods 34 at different positions are selected according to actual needs to work, push the cutter heads 33 to fall and pierce the cloth, and insert them into the first U-shaped pad 30, and then drive the cloth to move through the fixed conveying assembly 2. As the cloth moves, the multiple cutter heads 33 can automatically cut the cloth according to the appropriate width.

[0027] The first spring 35 is sleeved on the outer periphery of the top of the cutter head 33, one end of the first spring 35 is fixedly connected to the top of the cutter head 33, and the other end of the first spring 35 is fixedly connected to the top of the partition 32. When the hydraulic rod 34 works to push the cutter head 33 down, the first spring 35 on the cutter head 33 is compressed, and the first spring 35 on the cutter head 33 that is not working always maintains a rebound tendency, providing a vertical upward thrust to the cutter head 33 so that the cutter head 33 rises to the top of the partition 32, thereby realizing the operation of cutting fabrics according to different widths.

[0028] The cutting assembly 3 also includes a second U-shaped pad 4, an annular knife 40, a rotating shaft 41, a connecting frame 42, an electric slider 43 and a slide rail 44. The bottom of the second U-shaped pad 4 is fixedly connected to the top of the bottom plate 1. The annular knife 40 is rotatably connected to one end of the connecting frame 42 through the rotating shaft 41. The other end of the connecting frame 42 passes through the side wall of the second U-shaped pad 4 and is slidably connected thereto. The slide rail 44 is fixedly connected to the inner wall of one end of the second U-shaped pad 4. The electric slider 43 is slidably connected to the periphery of the slide rail 44. One end of the electric slider 43 is fixedly connected to the connecting frame 42. The second U-shaped pad 4 is used to support the cutting part of the cloth. When the cloth is cut to a suitable length, the electric slider 43 is activated to drive the connecting frame 42 to move horizontally along the slide rail 44. At this time, the annular knife 40 follows the connecting frame 42 to roll on the top of the second U-shaped pad 4, thereby cutting the cloth.

[0029] The fixed conveying assembly 2 includes two groups of clamping mechanisms 20, which are respectively located on both sides of the base plate 1. The clamping mechanism 20 includes a pair of pressure rollers 21, a pair of support plates 22, a pair of T-shaped sliders 23 and two pairs of second springs 24. The bottom of the support plate 22 is fixedly connected to the top of the base plate 1, and the two ends of the bottom pressure roller 21 are rotatably connected to the two support plates 22 respectively, and the two ends of the top pressure roller 21 are rotatably connected to the two T-shaped sliders 23 respectively. One end of the T-shaped slider 23 passes through the support plate 22 and is slidably connected thereto. One end of the second spring 24 is fixedly connected to the top of the T-shaped slider 23, and the other end of the second spring 24 is fixedly connected to the top wall of the support plate 22. The pressure rollers 21 are supported by the support plate 22, and one end of the cloth is passed through between the two groups of pressure rollers 21. The thrust provided by the second spring 24 keeps the top pressure roller 21 moving toward the bottom, so that the two groups of pressure rollers 21 clamp the two sides of the cloth, and then one of the pressure rollers 21 is rotated to drive the cloth to move by friction, and the remaining pressure rollers 21 will rotate along with the movement of the cloth, so that the cloth can be fixed and conveyed.

[0030] The fixed conveying assembly 2 also includes a resistance disc 25, which is rotatably connected to one of the pressure rollers 21 at the bottom, and the resistance disc 25 is fitted with one of the support plates 22. The ends of the resistance disc 25 opposite to the support plate 22 are fixedly connected with a plurality of elastic protrusions 26, which are distributed on the resistance disc 25 in a vertical circle, and the elastic protrusions 26 on the resistance disc 25 and the elastic protrusions 26 on the support plate 22 are in conflict with each other. When the pressure roller 21 rotates, the resistance disc 25 rotates with the pressure roller 21, and at this time, the elastic protrusions 26 on the resistance disc 25 and the elastic protrusions 26 on the support plate 22 are in conflict with each other, and deformed by force, so that the rotation of the pressure roller 21 is blocked, so that the cloth is pulled tight to both sides by friction, so that the cloth surface is kept under tension, and the cutting accuracy is further ensured.

[0031] The fixed conveying assembly 2 further includes a motor 27, which is fixedly connected to another support plate 22, and the output shaft of the motor 27 passes through the support plate 22 and is coaxially connected to another pressure roller 21 at the bottom. When the motor 27 is powered on, its output shaft can drive one of the pressure rollers 21 at the bottom to rotate, so that the cloth is conveyed while maintaining tension.

[0032] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention.
