Description

Technical Field

[0001] This utility model relates to the field of leather production equipment technology, specifically a cutting device for leather production. Background Technology

[0002] Leather cutting equipment is a professional piece of equipment used in the leather processing industry. It mainly consists of a frame, cutting blades, transmission mechanism, positioning device and control system. The blades are driven by a motor or hydraulic system to rotate or reciprocate at high speed. With the help of a precise positioning and guiding mechanism, it can accurately cut, slice or groove leather raw materials of different thicknesses and textures according to preset size, shape and process requirements.

[0003] For example, the Chinese authorized patent with publication number C211471453U, entitled "A Cutting Device for Leather Production", includes a working platform. The base surface of the working platform is fixedly connected to two symmetrically arranged first upright plates and two second upright plates. The base surface is provided with rectangular guide grooves and rectangular grooves. Two guide rods are horizontally fixedly connected between the two first upright plates and the two second upright plates. A feeding mechanism is slidably connected to the outer wall of the guide rods. A limit mechanism is rotatably connected to the side wall of the two first upright plates. A cutting mechanism is fixedly connected to the top of the two second upright plates. Blade guide grooves are provided on the opposite side walls. Several rolling rollers are rotatably connected to the inner wall of the rectangular grooves.

[0004] While the existing technologies can cut leather, they have low cutting efficiency, make it difficult to achieve continuous cutting, and the cutting accuracy is easily affected by the loosening of the leather during the cutting process. Therefore, they do not meet the current needs. In response, we propose a cutting device for leather production. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for leather production, so as to solve the problem mentioned in the background art that the cutting device is difficult to achieve continuous cutting while ensuring cutting accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for leather production, comprising a conveyor table, a cutting seat welded and fixed at the middle position of the upper surface of the conveyor table, a lifting plate installed inside the cutting seat, and the lifting plate slidingly limiting the inner cavity of the cutting seat, a cutter installed at the bottom of the lifting plate, and the cutter fixed to the lifting plate by bolts, a notch provided at the top of the lifting plate, a support plate welded and fixed at the rear side of the top of the cutting seat, a reduction motor fixedly installed above the support plate, an eccentric wheel installed on the output shaft of the reduction motor, and the lower end of the eccentric wheel located inside the notch, and leather guide seats provided at both the front and rear ends of the conveyor table, the front leather guide seat causing the rolled leather to move toward the cutting position of the cutting seat, and the rear leather guide seat removing the cut leather belt from the conveyor table.

[0007] Preferably, a cutting groove is provided at the middle position of the upper surface of the conveyor platform, and the cutting groove corresponds to the position of the cutter.

[0008] Preferably, a return spring is fixedly installed on both sides between the lifting plate and the inner cavity of the cutting seat.

[0009] Preferably, an upper roller is installed inside the leather guide seat, and a lower roller is rotatably installed inside the conveyor table at a position corresponding to the lower roller. Pulleys are rotatably installed at both the front and rear sides of one side of the conveyor table, and one end of each pulley is fixed to the lower roller. The two pulleys are connected by a belt drive. A fixed seat that is welded and fixed to the conveyor table is provided outside the front pulley, and a servo motor is fixedly installed outside the fixed seat.

[0010] Preferably, the inner sides of both plates of the leather guide seat are provided with limiting grooves, and sliding blocks are slidably installed inside the limiting grooves. The two ends of the upper roller are respectively connected to the sliding blocks through bearings, and a support spring is installed between the upper end of the sliding block and the limiting groove.

[0011] Preferably, electric push rods are fixedly installed on both sides of the upper surface of the leather guide seat, and pressure plates are fixedly installed on the movable ends of the electric push rods.

[0012] Preferably, the upper roller, lower roller, and pressure plate are made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a vertical reciprocating cutting mechanism. By activating a reduction motor, the output shaft drives an eccentric wheel to rotate. As the eccentric wheel slowly rotates, its protruding end enters the recess at the upper end of the lifting plate, gradually squeezing the recess and causing the lifting plate equipped with the cutter to move downwards. When the leather passes through the cutter below the cutting seat, the cutter can cut the leather at that position. Subsequently, the protruding end of the eccentric wheel gradually moves out from the other side of the recess, and the cutter returns to its original position upwards under the action of the return spring, allowing subsequent leather to enter. This process is repeated to achieve continuous and efficient cutting of leather.

[0015] 2. This utility model features leather guide seats at the front and rear of the cutting station. When the leather passes through the upper and lower rollers inside the leather guide seats, the upper roller presses the leather tightly under the action of the support spring, thus ensuring the clamping effect of the upper and lower rollers on the leather. Subsequently, the servo motor is turned on, driving the front pulley to rotate. The belt drive causes the rear pulley to rotate synchronously, and the shaft at one end of the pulley is connected to the lower roller. The front leather guide seat moves the rolled-up leather toward the cutting station, while the rear leather guide seat moves the cut leather out of the conveyor table. This realizes the fully automated operation of the leather from the rolled-up state to the completion of cutting and delivery, reducing manual intervention and labor intensity while ensuring the continuity of the cutting operation.

[0016] 3. This utility model features a pressure plate installed on the inner side of the lower end of the leather guide seat. With the cooperation of upper and lower rollers, the belt is transported to a suitable cutting position. Then, the electric push rod at the top of the leather guide seat is activated, and its movable end drives the pressure plate to descend. This clamps and fixes the leather at the front and rear ends of the cutting seat, effectively preventing dimensional deviations and irregular cuts caused by displacement of the leather during the cutting process. The pressure plate acts simultaneously at the front and rear ends of the cutting seat, forming a multi-point, all-round fixing effect, which greatly enhances the stability of the leather fixation.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a cutting device for leather production, including a conveyor table 1. A cutting seat 2 is welded and fixed at the middle position of the upper surface of the conveyor table 1. A lifting plate 3 is installed inside the cutting seat 2, and the lifting plate 3 slides and limits the inner cavity of the cutting seat 2. A cutter 4 is installed at the bottom of the lifting plate 3, and the cutter 4 is fixed to the lifting plate 3 by bolts. A notch 9 is provided at the top of the lifting plate 3. A support plate 6 is welded and fixed at the rear side of the top of the cutting seat 2. A reduction motor 7 is fixedly installed above the support plate 6. An eccentric wheel 8 is installed on the output shaft of the reduction motor 7, and the lower part of the eccentric wheel 8 is located inside the notch 9. Leather guide seats 10 are provided at both the front and rear ends of the conveyor table 1. Reset springs 22 are fixedly installed on both sides between the lifting plate 3 and the inner cavity of the cutting seat 2. The front leather guide seat 10 moves the rolled leather toward the cutting position of the cutting seat 2, and the rear leather guide seat 10 moves the cut belt out of the conveyor table 1.

[0024] When the geared motor 7 is turned on, its output shaft drives the eccentric wheel 8 to rotate. As the eccentric wheel 8 rotates, its protruding end enters the recess 9 at the upper end of the lifting plate 3, squeezing the recess and causing the lifting plate 3, which is equipped with the cutter 4, to move downwards. When the leather is located at the cutter 4 below the cutting seat 2, the cutter 4 completes the cutting of the leather. After the protruding end of the eccentric wheel 8 moves out from the other side of the recess 9, under the action of the return spring 22, the lifting plate 3 drives the cutter 4 to return upwards, waiting for the next cut. Stable cutting is achieved through mechanical transmission. The cooperation between the eccentric wheel 8 and the recess 9 makes the lifting and lowering movement of the cutter 4 precise and controllable, ensuring a neat cut and high precision. The return spring 22 assists the cutter 4 to return quickly, making the cutting process continuous and greatly improving the efficiency of leather cutting. At the same time, the mechanical structure is simple and reliable, reducing the risk of equipment failure and maintenance costs.

[0025] Please see Figure 1 and Figure 3A cutting groove 5 is provided at the middle position of the upper surface of the conveyor table 1, and the cutting groove 5 corresponds to the position of the cutter 4. The corresponding setting of the cutting groove 5 and the cutter 4 ensures the smoothness of the cutting process, prevents the cutter 4 from being unnecessarily obstructed during cutting, protects the cutter 4 and the conveyor table 1, and extends the service life of the equipment; at the same time, it also ensures that the leather is subjected to uniform force during cutting and ensures the cutting quality.

[0026] Please see Figure 2 and Figure 3 The leather guide seat 10 is equipped with an upper roller 11. The lower roller 12 is rotatably installed inside the conveyor table 1 at a position corresponding to the lower position of the upper roller 11. Pulleys 15 are rotatably installed on both the front and rear sides of one side of the conveyor table 1, and one end of the pulley 15 is fixed to the lower roller 12. The two pulleys 15 are connected by a belt 16. A fixed seat 17 is welded and fixed to the conveyor table 1 on the outside of the front pulley 15. A servo motor 18 is fixedly installed on the outside of the fixed seat 17. When the servo motor 18 is turned on, it drives the front pulley 15 to rotate. Through the transmission of the belt 16, the rear pulley 15 rotates synchronously. Since the shaft at one end of the pulley 15 is connected to the lower roller 12, the lower roller 12 rotates accordingly. The upper roller 11 presses the leather tightly under the action of the support spring 21. The upper and lower rollers cooperate to clamp the leather and realize the conveying. The front leather guide seat 10 moves the rolled leather toward the cutting station, and the rear leather guide seat 10 moves the cut leather out of the conveyor table 1.

[0027] Please see Figure 4 The leather guide seat 10 has limiting grooves 19 inside both side plates. Sliding blocks 20 are slidably installed inside the limiting grooves 19. The two ends of the upper roller 11 are connected to the sliding blocks 20 through bearings. A support spring 21 is installed between the upper end of the sliding block 20 and the limiting groove 19. When the leather passes through the upper roller 11 and the lower roller 12, the sliding block 20 slides in the limiting groove 19 under the elastic force of the support spring 21, driving the upper roller 11 to press the leather tightly, ensuring the clamping effect of the upper and lower rollers on the leather. When the leather thickness changes, the upper roller 11 can move up and down under the action of the support spring 21 to make adaptive adjustments.

[0028] Please see Figure 1 , Figure 2 and Figure 3Electric push rods 13 are fixedly installed on both sides of the upper surface of the leather guide seat 10. Pressure plates 14 are fixedly installed on the movable end of the electric push rods 13. After the upper and lower rollers transport the leather to the appropriate cutting position, the electric push rods 13 at the top of the leather guide seat 10 are opened, and their movable ends drive the pressure plates 14 to descend, thereby clamping and fixing the leather at the front and rear ends of the cutting seat 2 to prevent the leather from moving during the cutting process. After the cutting is completed, the electric push rods 13 drive the pressure plates 14 to rise and reset. The electric push rods 13 precisely control the descent of the pressure plates 14. Compared with manual fixing, the operation is efficient and the force is uniform, effectively avoiding dimensional deviations and irregular cuts caused by displacement during leather cutting.

[0029] Furthermore, the upper roller 11, lower roller 12, and pressure plate 14 are made of rubber. Rubber has good elasticity and friction. When the upper roller 11 and lower roller 12 clamp the leather, the rubber surface can fit tightly with the leather, increasing friction, preventing the leather from slipping, and ensuring stable conveying. When the pressure plate 14 is clamped, the rubber material can provide sufficient clamping force without damaging the leather surface.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
