Description

Technical Field

[0001] This utility model relates to the field of cutting machines, and more particularly to a conveying device for leather cutting. Background Technology

[0002] In leather processing, cutting is one of the key steps, and the stability of leather conveying directly affects cutting accuracy. Existing leather conveying devices mostly use a single conveyor roller, lacking an effective clamping structure. This leads to slippage and unstable conveying speed during transport. Simultaneously, the leather is prone to lateral shift during transport; without precise limiting structures, this can cause positional deviations during subsequent cutting, resulting in substandard dimensions.

[0003] When using the above technology, the following technical problems were found in the existing technology: At the moment of cutting, since the conveyor belt directly transports the leather, if the area of ​​the leather to be cut is not effectively fixed, it is easy to wrinkle or shift due to the force of the cutting blade, which further reduces the cutting accuracy. This problem is more prominent for soft and thin leather. To address this, we designed a conveyor device for leather cutting to provide another technical solution to the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a conveying device for leather cutting to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A conveying device for leather cutting includes a conveyor frame, a conveyor belt rotatably connected to the outer side of the conveyor frame, a frame body mounted at one end of the conveyor frame, a slidably connected outer side of the conveyor belt to the inner side of the frame body, leather placed on the surface of the conveyor belt, guide rails fixed on both sides of the inner side of the frame body, a resisting plate slidably connected to the top of the outer side of the guide rails, the resisting plate being located at the top of the inner side of the conveyor belt, a clamping cylinder mounted on both sides of the resisting plate, a connecting shaft fixed to the output end of the clamping cylinder passing through the resisting plate, and a clamping plate rotatably connected to the top of the connecting shaft.

[0007] The top of the resisting plate and the side of the clamping plate that are close to each other are both fixed with protective pads. The resisting plate and the clamping plate are used to clamp and transport the conveyor belt.

[0008] The top of the inner side of the frame is fixed with several guide rods, and the bottom of the protective pad is slidably connected to one of the guide rods.

[0009] The top of the inner side of the frame is rotatably connected to a transmission screw, and a servo motor is mounted on one end of the frame. The output end of the servo motor is fixed to the transmission screw, and the outer side of the transmission screw is threadedly connected to the resistance plate.

[0010] The outer side and middle part of the conveyor frame is equipped with a cutting device, which is used to cut leather.

[0011] The conveyor frame is equipped with positioning mechanisms for limiting the leather at both ends of the conveyor frame and at both ends of the cutting equipment. The positioning mechanism includes a clamping cylinder, a positioning clamp, and a linkage rod. The two sides of the conveyor frame and at both ends of the cutting equipment are equipped with clamping cylinders. The output end of the clamping cylinder is fixed with a linkage rod, and the top end of the linkage rod is fixed with a positioning clamp. The positioning clamp is used to limit the leather.

[0012] The bottom end of the positioning clamp is fixed with an anti-slip pad, which is used to increase the friction of the leather for positioning.

[0013] The outer side of the conveyor frame is equipped with a motor controller, which is electrically connected to the servo motor, clamping cylinder one, and clamping cylinder two via wires.

[0016] Before cutting, the positioning clamping plate is driven by the clamping cylinder two to limit the leather. In conjunction with the anti-slip pad, the friction is increased, which effectively prevents wrinkles from appearing during the leather conveying process and improves the flatness and quality of the cutting.

[0017] The protective pads on the inside of the resist plate and clamping plate can prevent damage to the leather surface during clamping and protect the appearance of the leather;

[0018] The motor controller coordinates the operation of the servo motor, clamping cylinder one, and clamping cylinder two to achieve automated conveying and positioning, improve cutting efficiency, and reduce human error. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-7This utility model provides a technical solution: a conveying device for leather cutting, including a conveyor frame 1, a conveyor belt 8 rotatably connected to the outer side of the conveyor frame 1, a frame 3 assembled at one end of the conveyor frame 1, the outer side of the conveyor belt 8 slidably connected to the inner side of the frame 3, leather placed on the surface of the conveyor belt 8, guide rails 7 fixed on both sides of the inner side of the frame 3, a resisting plate 17 slidably connected to the top of the outer side of the guide rail 7, the resisting plate 17 being located at the top of the inner side of the conveyor belt 8, clamping cylinders 13 assembled on both sides of the resisting plate 17, a connecting shaft 10 fixed through the resisting plate 17, and a clamping plate 9 rotatably connected to the top of the connecting shaft 10;

[0030] When it is necessary to cut the leather, the leather is placed on the conveyor belt 8 for conveying, so as to effectively convey the leather at equal intervals, thereby effectively processing and cutting the leather;

[0031] Protective pads 11 are fixed to the top of the resisting plate 17 and the side of the clamping plate 9 that are close to each other. The resisting plate 17 and the clamping plate 9 are used to clamp and transport the conveyor belt 8.

[0032] Specifically, when leather needs to be processed and transported, the clamping cylinder 13 is activated to drive the connecting shaft 10 and the clamping plate 9 to apply pressure to the conveyor belt 8, so that the resisting plate 17 and the clamping plate 9 drive the two corresponding protective pads 11 to transport the leather, making it easier for the conveyor belt 8 to transport the leather.

[0033] Several guide rods 6 are fixed to the top of the inner side of the frame 3, and the interior of one of the protective pads 11 at the bottom end is slidably connected to the guide rod 6;

[0034] A transmission screw 5 is rotatably connected to the top of the inner side of the frame 3. A servo motor 4 is installed at one end of the frame 3. The output end of the servo motor 4 is fixed to the transmission screw 5. The outer side of the transmission screw 5 is threadedly connected to the resisting plate 17.

[0035] Furthermore, when the servo motor 4 is started, it drives the transmission screw 5 to rotate. The transmission screw 5 drives the guide rail 7 to be threadedly connected, so that the clamping cylinder 13 drives the connecting shaft 10 and the clamping plate 9 to clamp the conveyor belt 8 between the clamping cylinder 13 and the resisting plate 17. This causes the transmission screw 5 to drive the resisting plate 17 and the protective pad 11 to clamp and pull the leather, so as to effectively rotate the conveyor belt 8 and thus effectively transport the leather at equal distances.

[0036] A cutting device 2 is mounted on the outer side and in the middle of the conveyor frame 1. The cutting device 2 is used to cut leather.

[0037] When the servo motor 4 is started, it drives the transmission screw 5 to convey the resisting plate 17 and the clamping plate 9, and the clamping cylinder 13 is started to drive the clamping plate 9 to clamp and convey it in the direction of the resisting plate 17. Then, the leather conveyed at equal intervals is cut by the cutting device 2.

[0038] Both ends of the conveyor frame 1 and both ends of the cutting device 2 are provided with positioning mechanisms for limiting the leather. The positioning mechanism includes a clamping cylinder 14, a positioning clamping plate 15 and a linkage rod 16. Both sides of the conveyor frame 1 and both ends of the cutting device 2 are equipped with clamping cylinders 14. The output end of the clamping cylinder 14 is fixed with a linkage rod 16. The top end of the linkage rod 16 is fixed with a positioning clamping plate 15. The positioning clamping plate 15 is used to limit the leather.

[0039] When leather needs to be cut, in order to improve the flatness of the cut, the clamping cylinder 14 needs to be activated to drive the linkage rod 16 and the positioning clamp 15 to position the leather, so as to effectively prevent the leather from wrinkling and causing poor cutting quality, thus affecting the appearance.

[0040] An anti-slip pad is fixed to the bottom of the positioning clamp 15. The anti-slip pad is used to increase the friction of the leather limiting position.

[0041] A motor controller 12 is mounted on the outside of the conveyor frame 1. The motor controller 12 is electrically connected to the servo motor 4, clamping cylinder 13 and clamping cylinder 2 14 via wires. The motor controller 12 first starts the clamping cylinder 13, which then drives the clamping plate 9 and the resisting plate 17 to clamp the conveyor belt 8. The servo motor 4 then drives the transmission screw 5 and the resisting plate 17 to pull the clamped conveyor belt 8. The distance that the transmission screw 5 drives the resisting plate 17 and the clamping plate 9 to pull the conveyor belt 8 is the same as the distance that the conveyor belt 8 rotates. At the same time, the conveyor belt 8 effectively drives the leather to be conveyed at equal distances.

[0042] Finally, the clamping cylinder 14 is activated to drive the linkage rod 16 and the positioning clamp 15 to position the conveyed leather and prevent wrinkles from forming. Therefore, the cutting device 2 is activated to cut the positioned leather.

[0043] The following is the usage process of the conveying device for leather cutting provided by this utility model:

[0044] First, place the leather on the conveyor belt 8 outside the conveyor frame 1. The motor controller 12 starts the clamping cylinder 13, so that its output end drives the clamping plate 9 to move closer to the resisting plate 17 through the connecting shaft 10. Together with the resisting plate 17 and the protective pad 11 on the inner side of the clamping plate 9, the leather is clamped on the conveyor belt 8.

[0045] The servo motor 4 at one end of the frame 3 is started, and its output end drives the transmission screw 5 inside the frame 3 to rotate. Since the transmission screw 5 is threadedly connected to the resisting plate 17, and the two sides of the resisting plate 17 slide along the guide rail 7 (while the bottom protective pad 11 slides along the guide rod 6), the resisting plate 17 drives the clamping plate 9 and the clamped leather to move synchronously. By controlling the rotation distance of the transmission screw 5, the conveyor belt 8 drives the leather to be conveyed at equal distances.

[0046] When the leather is conveyed to the cutting equipment 2, the motor controller 12 starts the clamping cylinders 14 on both sides of the conveyor frame 1, which drive the positioning clamp 15 to move down through the linkage rod 16. The anti-slip pad at the bottom of the positioning clamp 15 is used to limit and fix the leather to prevent wrinkles.

[0047] Finally, cutting device 2 cuts the positioned leather to complete one cutting operation;

[0048] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
