Description

Technical Field

[0001] The present invention belongs to the technical field of automotive interior processing, and specifically relates to a cutting device and a cutting method for automotive interior processing. Background Art

[0002] With the rapid development of the automotive industry towards high-end, intelligent, and personalized directions, consumers' requirements for the quality of automotive interiors are increasing day by day. In particular, the cutting accuracy, appearance flatness, and process efficiency of leather materials have become key indicators for measuring product competitiveness. In the production of interior components such as automotive seats, steering wheel covers, and door panel trims, leather materials are widely used due to their natural texture, soft touch, and aesthetics; After retrieval, for example, in the patent: CN219032223U, a cutting machine for automotive leather interior processing, includes a double-headed motor fixed in the middle of the bottom wall of the cutting table. Screw rods are fixed to the output shafts of the double-headed motor. Threaded blocks are threadedly connected to the outer peripheries of the screw rods, and sliders are fixed to the tops of the threaded blocks; this utility model starts the hydraulic cylinder after placing the leather fabric on the upper side of the cutting table. The output end of the hydraulic cylinder extends to lower the connecting rod and the paving roller. When the paving roller contacts the leather fabric, the double-headed motor is started. The output shafts of the double-headed motor rotate to drive the screw rods to rotate, thereby driving the threaded blocks to move outward through the screw rods. During the movement of the threaded blocks, the paving roller is driven to roll to both sides, so that the leather fabric is flatly laid on the upper side of the cutting table, greatly reducing the defective rate of leather processing; Currently, when the cutting device processes leather fabrics, the leather fabrics need to be first laid flat on the cutting table. After cutting, it is also necessary to manually remove and re-lay new leather fabrics. Since manual operations require frequent adjustments and the laying speed is limited by the proficiency of the operators, this process inevitably leads to a reduction in production efficiency.

Each limiting plate is slidably installed inside the support plate, and a third spring is arranged at the bottom end of the limiting plate.

[0013] A cutting method for a cutting device for processing automobile interior trims, comprising the following steps: S1: During operation, the pressure of the smoothing roller on the leather is first adjusted according to the characteristics of the leather fabric. The connecting plate is driven to move up and down by rotating the third threaded rod. When the connecting plate moves, the sleeve is driven to move up and down via the sliding rod. The movement of the sleeve drives the slider to slide on the inner wall of the spiral groove and drives the second threaded rod to rotate. The rotation of the second threaded rod drives the adjustment plate to move up and down, thereby changing the distance between the adjustment plate and the bottom plate, changing the elastic pressure of the first spring, and thus adjusting the pressure of the smoothing roller on the leather; S2: The leather to be cut is then placed on the top of the conveying structure, and is conveyed to one side of the cutting structure through the conveying structure, so that the cutting line moves to the bottom of the cutting structure; S3: Then start the motor to drive the first threaded rod to rotate. The rotation of the first threaded rod drives the movement of the movable seat. The movement of the movable seat drives the movement of the first connecting shaft, so that the first connecting shaft slides in the inner wall of the slide groove. At the same time, the movement of the first connecting shaft drives the movement of the connecting seat. The movement of the connecting seat drives the movement of the second connecting shaft. The movement of the second connecting shaft drives the movement of the first rotating shaft. The movement of the first rotating shaft drives the movement of the smoothing roller. At the same time, the movement of the first rotating shaft drives the movement of the gear, which meshes with the rack plate and rotates. The rotation of the gear drives the rotation of the first rotating shaft, and the rotation of the first rotating shaft drives the rotation of the smoothing roller. The sliding friction is converted into rolling friction through rotation, so that the two smoothing rollers move from the inside to the outside and rotate simultaneously to smooth the leather. S4: When the two smoothing rollers move outward from the cutting line, the leather is cut by the cutting mechanism; S5: When the smoothing roller moves from the inside to the outside to the right side of the chute, the first connecting shaft is connected to the magnetic plate through the opposite magnetic connection, causing the first connecting shaft to move upward, and similarly driving the smoothing roller to move upward and separate from the leather, so that the smoothing roller does not contact the leather when it is reset; S6: After cutting, the leather is conveyed again through the conveying structure, and the above steps are repeated for continuous operation.

[0014] The beneficial effects of the present invention are as follows: In the present invention, through the provision of a flattening component, during operation, the leather to be cut is placed on the top of the conveying structure and conveyed to one side of the cutting structure by the conveying structure, so that the cutting line moves to the lower part of the cutting structure. Then, the motor is started to drive the first threaded rod to rotate. The rotation of the first threaded rod drives the movement of the moving seat, and the movement of the moving seat drives the movement of the first connecting shaft, so that the first connecting shaft slides on the inner wall of the chute. At the same time, the movement of the first connecting shaft drives the movement of the connecting seat, the movement of the connecting seat drives the movement of the second connecting shaft, the movement of the second connecting shaft drives the movement of the first rotating shaft, and the movement of the first rotating shaft drives the movement of the flattening roller, so that the two flattening rollers flatten the leather from the inside out. After the two flattening rollers move away from the cutting line, the leather is cut by the cutting structure. After cutting, the leather is continuously conveyed by the conveying structure again, and the above steps are repeated for continuous operation, which helps to improve the production efficiency of automobile interior trimming.

[0015] In the present invention, through the provision of a rotating component, when the flattening roller moves outwards to flatten the leather, the gear meshes with the rack plate and rotates. The rotation of the gear drives the rotation of the first rotating shaft, and the rotation of the first rotating shaft drives the rotation of the flattening roller. By rotation, the sliding friction is converted into rolling friction, and the frictional force is reduced to reduce the drag on the leather surface, reduce material stretching and deformation, and improve the efficiency and effect of eliminating wrinkles.

[0016] In the present invention, two second threaded rods are connected by a connecting plate for synchronous adjustment. During adjustment, the third threaded rod is rotated to drive the connecting plate to move up and down. When the connecting plate moves, the collar is driven to move up and down by the sliding rod. The movement of the collar drives the slider to slide on the inner wall of the spiral groove and drives the second threaded rod to rotate, thereby moving and adjusting the adjusting plate. The two second threaded rods are connected by a connecting plate for synchronous adjustment, which helps to improve the adjustment efficiency. Brief Description of the Drawings

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 8 shown, in the embodiment of the present invention, a cutting device for automobile interior decoration processing includes a cutting table 1. A support plate 3 is fixedly installed at the top end of the cutting table 1. A top plate 4 is fixedly connected to the top end of the support plate 3. A cutting structure 5 is installed at the bottom end of the top plate 4. A conveying structure 2 is arranged below the cutting structure 5. The conveying structure 2 is installed inside the cutting table 1. A smoothing assembly is arranged at the top end of the conveying structure 2; The smoothing assembly includes smoothing rollers 6 arranged at the top end of the conveying structure 2. There are two smoothing rollers 6. First rotating shafts 7 are fixedly connected to the inner walls of the two smoothing rollers 6. One ends of the two first rotating shafts 7 are both installed with second connecting shafts 16 through rotating assemblies. Connecting seats 9 are installed on the outer walls of the two second connecting shafts 16. First connecting shafts 10 are fixedly connected to one sides of the two connecting seats 9. Moving seats 11 are installed on the outer walls of the two first connecting shafts 10. One ends of the two first connecting shafts 10 are both embedded in the inner wall of the chute 14. The chute 14 is opened on the inner wall of the support plate 3; Both of the two moving seats 11 are installed on the outer wall of the first threaded rod 12. One end of the first threaded rod 12 is installed with a motor 13.

[0021] Existing: CN219032223U discloses a cutting machine for automobile leather interior decoration processing. The cutting table 1, support plate 3, top plate 4 and cutting structure 5 proposed in the present application document are disclosed in this patent. These technical means will not be elaborated one by one here; The outer wall of the first threaded rod 12 is provided with two threads, and the directions of the two threads are set in opposite directions, which are used to make the two moving seats 11 move relatively; During operation, the leather to be cut is placed on the top of the conveying structure 2, and is conveyed to one side of the cutting structure 5 by the conveying structure 2, so that the cutting line moves to the lower part of the cutting structure 5; Then, start the motor 13 to drive the first threaded rod 12 to rotate. The rotation of the first threaded rod 12 drives the movement of the moving seat 11. The movement of the moving seat 11 drives the movement of the first connecting shaft 10, so that the first connecting shaft 10 slides in the inner wall of the chute 14. At the same time, the movement of the first connecting shaft 10 drives the movement of the connecting seat 9. The movement of the connecting seat 9 drives the movement of the second connecting shaft 16. The movement of the second connecting shaft 16 drives the movement of the first rotating shaft 7. The movement of the first rotating shaft 7 drives the movement of the flattening roller 6, so that the two flattening rollers 6 flatten the leather from the inside to the outside. After the two flattening rollers 6 move away from the cutting line, the leather is cut by the cutting structure 5. After cutting, the leather is continuously conveyed by the conveying structure 2 again, and the above steps are repeated for continuous operation, which helps to improve the production efficiency of automobile interior decoration processing; The method of conveying leather materials through the conveying structure 2 can be used when performing cutting or non-cutting operations.

[0022] Such as Figure 7 shown, the first connecting shaft 10 is slidably connected with the moving seat 11.

[0023] Such as Figure 8 shown, magnetic plates 15 are fixedly installed on both top sides of the inner wall of the chute 14.

[0024] The first connecting shaft 10 is magnetically connected with the two magnetic plates 15; The magnetic plate 15 located above the left side of the chute 14 is connected with the first connecting shaft 10 by the same-sex magnetic pole, and the magnetic plate 15 located above the right side of the chute 14 is connected with the first connecting shaft 10 by the opposite-sex magnetic pole; When the flattening roller 6 moves from the inside to the outside to the right side of the chute 14, the first connecting shaft 10 moves upward through the opposite-sex magnetic connection between the first connecting shaft 10 and the magnetic plate 15. Similarly, it drives the flattening roller 6 to move, so that the flattening roller 6 moves upward and separates from the leather, so that the flattening roller 6 does not contact the leather during reset, eliminating the influence of friction, ensuring the flatness of the cutting edge, and improving the cutting accuracy.

[0025] Such as Figure 4 、 Figure 5 and Figure 7 shown, the rotating assembly includes a gear 21 fixedly installed at one end of the first rotating shaft 7, and a rack plate 22 is meshed at the bottom end of the gear 21. The rack plate 22 is arranged on one side of the support plate 3.

[0026] When the flattening roller 6 moves outwards to flatten the leather, the gear 21 meshes with the rack plate 22 and rotates. The rotation of the gear 21 drives the rotation of the first rotating shaft 7, and the rotation of the first rotating shaft 7 drives the rotation of the flattening roller 6. By rotating, the sliding friction is converted into rolling friction, reducing the frictional force to reduce the drag on the leather surface, reducing material stretching and deformation, and improving the efficiency and effect of eliminating wrinkles.

[0027] As Figures 4 to 7 shown, a second threaded rod 17 is rotatably installed on the inner wall of the connecting seat 9. A bottom plate 18 and an adjusting plate 20 are installed on the outer wall of the second threaded rod 17, and a first spring 19 is arranged between the bottom plate 18 and the adjusting plate 20.

[0028] The bottom end of the second threaded rod 17 passes through the inner wall of the second connecting shaft 16 and is finally rotatably connected to the connecting seat 9. The second threaded rod 17 is slidably connected to the second connecting shaft 16; When the second connecting shaft 16 moves due to the elasticity of the first spring 19, the position of the second connecting shaft 16 during movement is guided and limited by the second threaded rod 17; Due to the elastic potential energy of the first spring 19, the bottom plate 18 always has a tendency to move downwards, causing the bottom plate 18 to press the second connecting shaft 16 downwards. Similarly, the second connecting shaft 16 drives the flattening roller 6 to press down and contact the surface of the leather material, preventing texture direction, uneven thickness, and elastic differences on the leather surface. Traditional rigid rollers are prone to wrinkles or tears due to excessive local pressure. The elastic flattening roller 6 undergoes a small deformation when contacting the leather and releases local high pressure through compression, ensuring uniform pressure distribution.

[0029] As Figure 6 and Figure 7 shown, the bottom plate 18 is rotatably connected to the second threaded rod 17, and the bottom plate 18 is threadedly connected to the adjusting plate 20.

[0030] When cutting different types of automotive interior leather, the adjusting plate 20 can be driven to move up and down by rotating the second threaded rod 17 to change the distance between the adjusting plate 20 and the bottom plate 18, thereby adjusting the elastic pressure of the first spring 19, and thus changing the pressure of the flattening roller 6 on the leather, adapting to the processing of various materials and reducing the process switching cost.

[0031] Automotive interior leather includes natural cowhide, artificial leather, ultra-fine leather, etc., and there are significant differences in their thickness, elastic modulus, and surface texture.

[0032] As Figures 4 to 7 shown, a spiral groove 28 is formed on the outer wall of the top of the second threaded rod 17. A slider 27 is slidably connected to the inner wall of the spiral groove 28. The slider 27 is fixedly installed on the inner wall of the collar 25, and the collar 25 is sleeved on the outer wall of the second threaded rod 17; On both sides of the collar 25, sliding rods 26 are fixedly installed. A connecting plate 23 is installed outside the sliding rods 26. A third threaded rod 29 is threadedly connected to the middle of the connecting plate 23. The bottom end of the third threaded rod 29 is rotatably installed with a base plate 30, and the base plate 30 is slidably installed on one side of the support plate 3.

[0033] During adjustment, by rotating the third threaded rod 29, the connecting plate 23 is driven to move up and down. When the connecting plate 23 moves, the collar 25 is driven to move up and down through the sliding rods 26. The movement of the collar 25 drives the slider 27 to slide on the inner wall of the spiral groove 28 and drives the second threaded rod 17 to rotate, thereby moving and adjusting the adjusting plate 20. The two second threaded rods 17 are connected by the connecting plate 23 for synchronous adjustment, which helps to improve the adjustment efficiency.

[0034] As Figure 4 、 Figure 5 and Figure 6 shown, the sliding rod 26 is slidably connected to the connecting plate 23.

[0035] As Figure 4 and Figure 5 shown, a limiting plate 31 is fixedly connected to the side wall of the rack plate 22. The limiting plates 31 are distributed at both ends and the middle of the rack plate 22. Each limiting plate 31 is slidably installed inside the support plate 3, and a third spring 32 is arranged at the bottom end of the limiting plate 31.

[0036] Due to the elastic potential energy of the third spring 32, the limiting plate 31 always has a tendency to move upward, thereby ensuring the meshing stability between the rack plate 22 and the gear 21 after the pressure of the flattening roller 6 is adjusted.

[0037] A cutting method for a cutting device used in automotive interior processing includes the following steps: S1: During operation, first adjust the pressure of the flattening roller 6 on the leather according to the characteristics of the leather fabric. By rotating the third threaded rod 29, the connecting plate 23 is driven to move up and down. When the connecting plate 23 moves, the collar 25 is driven to move up and down through the sliding rods 26. The movement of the collar 25 drives the slider 27 to slide on the inner wall of the spiral groove 28 and drives the second threaded rod 17 to rotate. The rotation of the second threaded rod 17 drives the adjusting plate 20 to move up and down to change the distance between the adjusting plate 20 and the bottom plate 18, and change the elastic pressure of the first spring 19, thereby adjusting the pressure of the flattening roller 6 on the leather; S2: Then place the leather to be cut on the top of the conveying structure 2, and convey it to one side of the cutting structure 5 through the conveying structure 2, so that the cutting line moves to the lower part of the cutting structure 5; S3: Then start the motor 13 to drive the first threaded rod 12 to rotate. The rotation of the first threaded rod 12 drives the movement of the movable seat 11. The movement of the movable seat 11 drives the movement of the first connecting shaft 10, so that the first connecting shaft 10 slides in the inner wall of the slide groove 14. At the same time, the movement of the first connecting shaft 10 drives the movement of the connecting seat 9. The movement of the connecting seat 9 drives the movement of the second connecting shaft 16. The movement of the second connecting shaft 16 drives the movement of the first rotating shaft 7. The movement of the first rotating shaft 7 drives the movement of the smoothing roller 6. At the same time, the movement of the first rotating shaft 7 drives the movement of the gear 21, and the gear 21 meshes with the rack plate 22 to rotate. The rotation of the gear 21 drives the rotation of the first rotating shaft 7, and the rotation of the first rotating shaft 7 drives the rotation of the smoothing roller 6. The sliding friction is converted into rolling friction through rotation, so that the two smoothing rollers 6 move from the inside to the outside and rotate simultaneously to smooth the leather; S4: After the two smoothing rollers 6 move outward from the cutting line, the leather is cut by the cutting mechanism 5; S5: When the smoothing roller 6 moves from the inside to the outside to the right side of the chute 14, the first connecting shaft 10 is connected to the magnetic plate 15 by anisotropic magnetic connection, so that the first connecting shaft 10 moves upward, and similarly drives the smoothing roller 6 to move, so that the smoothing roller 6 moves upward and separates from the leather, so that the smoothing roller 6 does not contact the leather when it is reset; S6: After cutting, the leather is conveyed again through the conveying structure 2, and the above steps are repeated for continuous operation.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

The gear (21) meshes with the rack plate (22) and rotates. The rotation of the gear (21) drives the rotation of the first rotating shaft (7). The rotation of the first rotating shaft (7) drives the rotation of the flattening roller (6). By rotation, the sliding friction is converted into rolling friction, so that the two flattening rollers (6) move from the inside to the outside and rotate at the same time to flatten the leather; S4: After the two flattening rollers (6) move away from the cutting line, the leather is cut by the cutting structure (5); S5: When the flattening roller (6) moves from the inside to the outside to the right side of the sliding groove (14), the first connecting shaft (10) moves upward through the opposite-sex magnetic connection between the first connecting shaft (10) and the magnetic plate (15). Similarly, the flattening roller (6) is driven to move, so that the flattening roller (6) moves upward and separates from the leather, so that the flattening roller (6) does not contact the leather when resetting; S6: After cutting, continue to convey the leather through the conveying structure (2) again, and repeat the above steps for continuous operation.
