Description

Technical Field

[0001] This application relates to the field of automotive interior parts, and in particular to an automotive interior parts processing and cutting device. Background Technology

[0002] Automotive interior parts are an important component of a car, involving all aspects of the car's interior. These include items such as steering wheel covers, car seat cushions, car floor mats, car ornaments, interior decorations, and storage boxes. Automotive interior parts not only serve a decorative purpose but also play an important role in the car's safety and functionality.

[0003] When processing automotive interior parts such as car seat cushions and floor mats, flexible materials such as felt, non-woven fabric, and leather need to be cut to appropriate sizes. The materials and interior parts are then tightly bonded together through manual sewing, extrusion, and other methods to meet the decorative, safety, and functional requirements of the automotive interior parts.

[0004] Currently, when processing automotive interior parts, the dimensional deviations of flexible materials such as felt, non-woven fabric, and leather are prone to occur during cutting due to the presence of wrinkles, which affects the subsequent processing of automotive interior parts. Utility Model Content

[0005] To improve the accuracy of cutting automotive interior parts, this application provides an automotive interior parts processing and cutting device.

[0006] The automotive interior parts processing and cutting device provided in this application adopts the following technical solution:

[0007] A cutting device for processing automotive interior parts includes a body, a conveyor belt disposed on the body, and a cutting mechanism for cutting flexible materials. The device is characterized in that: the body is provided with a limiting mechanism for limiting the displacement of the flexible materials, and the cutting mechanism includes a cutting blade disposed on the body and a cutting slit formed on the body and located directly below the cutting blade.

[0008] The machine body is provided with a movable plate, on which a first pressure roller and a second pressure roller are rotatably connected. The machine body is provided with an adjustment component for adjusting the lifting and lowering of the movable plate. The first pressure roller is located on the side away from the cutting blade, and the second pressure roller is located on the side closer to the cutting blade. The machine body is also provided with a drive mechanism for driving the first pressure roller and the second pressure roller to run.

[0009] By adopting the above technical solution, the conveyor belt transports the flexible material to the first and second pressure rollers. The drive mechanism drives the first and second pressure rollers to rotate, making their speeds different. The adjustment component adjusts the height of the first and second pressure rollers from the conveyor belt according to the thickness of the flexible material, so that the second pressure roller generates a certain frictional force on the flexible material on the conveyor belt. This causes the second pressure roller to flatten the wrinkled flexible material. The limiting mechanism adjusts the flexible material that has deviated on the conveyor belt and prevents the flexible material from moving on the conveyor belt. The first and second pressure rollers effectively eliminate wrinkles in the flexible material, and the limiting mechanism prevents deviation during the transportation of the flexible material, thus improving the accuracy of flexible material processing.

[0010] Optionally, the adjustment assembly includes a lead screw rotatably connected to the machine body, a worm gear coaxially fixed to the lead screw, and a worm gear rotatably connected to the machine body. The lead screw is threaded through the movable plate, the worm gear meshes with the worm gear, and a movable rod is fixedly connected to the side of the machine body away from the lead screw. The movable rod slides through the movable plate.

[0011] By adopting the above technical solution, when flexible materials of different thicknesses pass through the first and second pressure rollers, the worm gear on the machine body rotates, driving the worm wheel to rotate. The lead screw fixed to the worm wheel rotates with the worm wheel, and the lead screw thread passes through the movable plate, driving the movable plate to move. The height of the first and second pressure rollers from the conveyor belt changes. The movement of the movable plate is driven by the worm gear, worm wheel, and lead screw, thereby adjusting the height of the first and second pressure rollers from the conveyor belt. This effectively prevents the drive mechanism fixed to the movable plate from shaking during operation. When the lead screw drives the movable plate to move, the movable plate at the end away from the lead screw moves simultaneously along the moving rod, ensuring that the first and second pressure rollers are evenly pressed against the flexible material, while preventing the movable plate from rotating when it is raised or lowered.

[0012] Optionally, the drive mechanism includes a motor fixed to the movable plate, a sprocket fixed to one end of the first pressure roller, a driven wheel fixed to the second pressure roller, and a chain meshing with the sprocket and the driven wheel. The output end of the motor is fixed to the end of the first pressure roller away from the sprocket, and the number of teeth on the sprocket is greater than the number of teeth on the driven wheel.

[0013] By adopting the above technical solution, when the motor is started, the motor drives the first pressure roller to rotate, the sprocket fixed on the first pressure roller drives the chain to rotate, the chain drives the driven wheel to rotate, and the second pressure roller rotates with the driven wheel. The motor controls the rotation speed of the first pressure roller to be the same as the speed at which the conveyor belt conveys the flexible material. The number of teeth on the sprocket is greater than the number of teeth on the driven wheel, and the rotation speed of the second pressure roller is greater than the speed of the first pressure roller. The second pressure roller generates a pulling force on the flexible material perpendicular to the direction of the first pressure roller, so that the wrinkles on the flexible material along the conveyor belt conveying direction are flattened.

[0014] Optionally, the limiting mechanism includes a slide rod fixedly connected to the machine body, a connecting rod slidably connected to the slide rod, a pad fixedly connected to one end of the connecting rod near the conveyor belt, and a pressure plate located above the pad and slidably connected to the connecting plate. The connecting rod and the slide rod are provided with screws for fixing, and the connecting rod and the pressure plate are provided with screws for fixing.

[0015] By adopting the above technical solution, when the flexible material passes through the limiting mechanism, it is conveyed between the pad and the pressure plate through the sliding connecting rod. The edge of the flexible material abuts against the connecting rod, which can adjust the position of the flexible material on the conveyor belt and prevent the flexible material from deviating on the conveyor belt.

[0016] Optionally, the pressure plate has a waist-shaped hole, and the pressure plate is provided with a slider that matches the waist-shaped hole. The slider is threaded with a blade, and the slider is fixed with a screw for fastening the slider. The screw passes through the waist-shaped hole.

[0017] By adopting the above technical solution, when it is necessary to cut the width of the flexible material, the slider on the pressure plate is moved, the position of the slider in the oblong hole is adjusted, and the screw is turned to fix the slider in the oblong hole. The slider is fixed with a blade by the screw. The blade can cut the width of the flexible material within the length range of the oblong hole, which can meet the requirements of the processing size of the flexible material.

[0018] Optionally, both the first pressure roller and the second pressure roller are provided with threaded protrusions with opposite directions of rotation along the center symmetrically.

[0019] By adopting the above technical solution, the threaded protrusions with opposite rotation directions can stretch the flexible material along the axial direction of the first pressure roller and the axial direction of the second pressure roller, thereby eliminating wrinkles in the flexible material parallel to the direction of the first pressure roller.

[0020] Optionally, the surfaces of the first and second pressure rollers are bonded with an anti-slip layer.

[0021] By adopting the above technical solution, the anti-slip layer can enhance the friction between the first and second pressure rollers and the flexible material, and at the same time prevent the flexible material from being deformed due to excessive stretching.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the flexible material is conveyed to the first and second pressure rollers, the motor drives the first pressure roller to rotate. The first pressure roller drives the second pressure roller to rotate through a sprocket, driven wheel, and chain. The number of teeth on the sprocket is greater than the number of teeth on the driven wheel. The motor controls the rotation speed of the first pressure roller to be the same as the speed at which the conveyor belt conveys the flexible material. The rotation speed of the second pressure roller is greater than the speed of the first pressure roller. The first and second pressure rollers flatten the wrinkles on the flexible material that are parallel to the axial direction of the first pressure roller, thereby eliminating the wrinkles on the flexible material that are parallel to the axial direction of the first pressure roller and improving the accuracy of processing the flexible material.

[0024] 2. When the flexible material is conveyed to the first pressure roller and the second pressure roller, both the first pressure roller and the second pressure roller are provided with threaded protrusions that are symmetrical about the center and rotate in opposite directions. The threaded protrusions generate a pulling force on the flexible material that is parallel to the axial direction of the first pressure roller, thereby eliminating wrinkles on the flexible material that are perpendicular to the axial direction of the first pressure roller and improving the accuracy of cutting and processing the flexible material.

[0025] 3. When flexible materials of different thicknesses pass through the first and second pressure rollers, the worm gear rotates, which drives the worm wheel to rotate. The worm wheel drives the lead screw to rotate. The lead screw thread passes through the movable plate, and the movable plate rises and falls with the rotation of the lead screw. The side of the movable plate away from the lead screw slides with the moving rod. When the motor on the movable plate is running, the worm wheel, worm gear, and lead screw can prevent the movable plate from shaking with the motor. The height of the first and second pressure rollers relative to the conveyor belt can be adjusted according to the thickness of the flexible material.

[0026] 4. When the flexible material passes through the limiting mechanism, it is transported between the pressure plate and the pad. The edge of the flexible material abuts against the connecting rod. By moving the position of the connecting rod on the slide bar, the position of the flexible material on the conveyor belt can be adjusted. The blades on the pressure plate can cut the width of the flexible material, avoiding the problem of deviation in the cutting size caused by the position of the flexible material on the conveyor belt, while meeting the requirements for the cutting width of the flexible material.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a cutting apparatus for processing automotive interior parts. (Refer to...) Figure 1 , Figure 2 and Figure 3 An automotive interior parts processing and cutting device includes a body 1, a conveyor belt 2 mounted on the body 1, and a cutting mechanism 3 for cutting flexible materials. The cutting mechanism 3 includes a cutting blade 31 mounted on the body 1 and a cutting slit 32 formed on the body 1 directly below the cutting blade 31. A limiting mechanism 4 is provided on the body 1 to restrict the movement of the flexible material. A movable plate 5 is provided on the body 1, and a first pressure roller 6 and a second pressure roller 7 are rotatably connected to the movable plate 5. An adjusting component 9 is provided on the body 1 to adjust the lifting and lowering of the movable plate 5. The movable plate 5 is provided with a drive mechanism for driving the first pressure roller 6 and the second pressure roller 7. The first pressure roller 6 is located on the side away from the cutting blade 31, and the second pressure roller 7 is located on the side close to the cutting blade 31. The drive mechanism includes a motor 84 fixed to the movable plate 5, a sprocket 81 fixed to one end of the first pressure roller 6, a driven wheel 82 fixed to one end of the second pressure roller 7, and a chain 83 meshing with the sprocket 81 and the driven wheel 82. The motor 84 is fixed to the side of the movable plate 5 away from the sprocket 81, and the output end of the motor 84 is fixed to the first pressure roller 6.

[0034] When the conveyor belt 2 transports the flexible material to the first pressure roller 6 and the second pressure roller 7, the motor 84 drives the first pressure roller 6 to rotate. The number of teeth on the sprocket 81 is greater than the number of teeth on the driven wheel 82. The rotation speed of the second pressure roller 7 is greater than the rotation speed of the first pressure roller 6. The motor 84 controls the rotation speed of the first pressure roller 6 to be consistent with the speed at which the conveyor belt 2 transports the flexible material. When the flexible material is transported between the first pressure roller 6 and the second pressure roller 7, because the rotation speed of the second pressure roller 7 is greater than that of the first pressure roller 6, the second pressure roller 7 generates a pulling force on the flexible material perpendicular to the axial direction of the first pressure roller 6, thereby eliminating wrinkles in the flexible material parallel to the axial direction of the first pressure roller 6. The limiting mechanism 4 adjusts the position of the flexible material on the conveyor belt 2 and prevents the flexible material from shifting on the conveyor belt 2. The cutting blade 31 cuts the flexible material, which has passed through the leveling mechanism and the limiting mechanism 4, into semi-finished products of appropriate size, thereby avoiding the problem of low processing accuracy caused by wrinkles in the flexible material.

[0035] Reference Figure 1 and Figure 3 The adjusting assembly 9 includes a lead screw 91 rotatably connected to the machine body 1, a worm gear 92 coaxially fixed to the lead screw 91, and a worm 93 rotatably connected to the machine body 1. The lead screw 91 is threaded through the movable plate 5, and the worm 93 and the worm gear 92 mesh with each other. A movable rod 10 is fixedly connected to the side of the machine body 1 away from the lead screw 91, and the movable rod 10 slides through the movable plate 5.

[0036] When flexible materials of different thicknesses pass through the first pressure roller 6 and the second pressure roller 7, the worm 93 is rotated, which drives the worm wheel 92 to rotate. The lead screw 91, which is coaxially fixed to the worm wheel 92, rotates with the worm wheel 92. The lead screw 91 is threaded through the movable plate 5, and the movable plate 5 rises and falls with the rotation of the lead screw 91. The side of the movable plate 5 away from the lead screw 91 slides with the moving rod 10, thereby adjusting the height of the first pressure roller 6 and the second pressure roller 7, which are rotatably connected to the movable plate 5, to the conveyor belt 2, so that the surfaces of the first pressure roller 6 and the second pressure roller 7 are in uniform contact with the flexible material.

[0037] Reference Figure 1 and Figure 4 The limiting mechanism 4 includes a slide rod 41 rotatably connected to the machine body 1, a connecting rod 42 slidably connected to the slide rod 41, a pad 43 fixed to one end of the connecting rod 42 near the conveyor belt 2, and a pressure plate 44 located above the pad 43 and slidably connected to the connecting rod 42. One end of the connecting rod 42 is screwed against the slide rod 41. (Refer to...) Figure 4In other feasible embodiments, the slide bar 41 can also be a threaded bar, and the position of the connecting rod 42 on the threaded bar can be adjusted by rotating the threaded bar; one end of the pressure plate 44 is abutted against the connecting rod 42 with a screw; the pad 43 is a hard and smooth thin iron plate; the pad 43 is in contact with the conveyor belt 2; the pressure plate 44 has a waist-shaped hole 441 in the direction perpendicular to the conveyor belt 2; one end of the waist-shaped hole 441 has a larger opening; a slider 442 is provided in the waist-shaped hole 441; the pressure plate 44 has a scale at the waist-shaped hole 441; the slider 442 has a groove for clamping the blade 443; the slider 442 has a threaded hole; the screw passes through the threaded hole and abuts against the blade 443; one end of the slider 442 is abutted against the pressure plate 44 with a screw.

[0038] When the flexible material passes through the limiting mechanism 4, it is conveyed between the pad 43 and the pressure plate 44. The edge of the flexible material is in contact with the connecting rod 42. The position of the connecting rod 42 on the slide rod 41 is adjusted, and the connecting rod 42 is fixed to the slide rod 41 by tightening the screws at the connection between the connecting rod 42 and the slide rod 41. This adjusts the position of the flexible material on the conveyor belt 2, preventing the flexible material from shifting and ensuring that the flexible material is transported in a straight line on the conveyor belt 2. When it is necessary to cut the width of the flexible material, the position of the slider 442 in the groove is adjusted according to the scale on the pressure plate 44, and the slider 442 and the pressure plate 44 are fixed by tightening the screws to prevent the slider 442 and the pressure plate 44 from moving. The limiting mechanism 4 solves the problem of the flexible material shifting on the conveyor belt 2, ensuring that the flexible material is transported evenly on the conveyor belt 2. At the same time, it can cut and adjust the width of the flexible material with uneven edges, ensuring that the dimensional requirements of the flexible material are met during processing.

[0039] Reference Figure 1 The first pressure roller 6 and the second pressure roller 7 are provided with threaded protrusions that are symmetrical about the center and rotate in opposite directions. The first pressure roller 6 and the second pressure roller 7 are provided with anti-slip layers. The anti-slip layer material can be elastic rubber, and the anti-slip layer covers the threaded protrusions.

[0040] The oppositely spiraling threaded protrusions on the first pressure roller 6 and the second pressure roller 7 can generate a pulling force on the flexible material parallel to the axial direction of the first pressure roller 6, eliminating wrinkles on the flexible material perpendicular to the axial direction of the first pressure roller 6. The anti-slip layer is made of elastic rubber, which can increase the friction between the first pressure roller 6 and the second pressure roller 7 and the flexible material, and can adjust the height of the first pressure roller 6 and the second pressure roller 7 on the conveyor belt 2 for flexible materials of different thicknesses.

[0041] The implementation principle of the automotive interior parts processing and cutting device in this application embodiment is as follows: When the conveyor belt 2 transports the flexible material between the first pressure roller 6 and the second pressure roller 7, the motor 84 drives the first pressure roller 6 to rotate and controls the rotation speed of the first pressure roller 6 to be consistent with the speed of the conveyor belt 2 transporting the flexible material. The motor 84 drives the second pressure roller 7 to rotate through the transmission of the sprocket 81, chain 83 and driven wheel 82. Since the number of teeth of the sprocket 81 is greater than the number of teeth of the driven wheel 82, the rotation speed of the first pressure roller 6 is greater than the speed of the second pressure roller 7. The second pressure roller 7 flattens the wrinkles on the flexible material perpendicular to the axial direction of the first pressure roller 6. The surfaces of pressure rollers 6 and 7 are provided with threaded protrusions to further flatten wrinkles on the flexible material parallel to the axial direction of the first pressure roller 6. By rotating the worm gear 93, the worm gear 93 drives the worm wheel 92 to rotate, the worm wheel 92 drives the lead screw 91 to rotate, and the lead screw 91 drives the movable plate 5 to rise and fall. The height of the first pressure roller 6 and the second pressure roller 7 on the conveyor belt 2 can be adjusted according to the thickness of different flexible materials. The limiting mechanism 4 can adjust the position of the material on the conveyor belt 2, and can also cut the width of the flexible material. The flexible material is conveyed by the conveyor belt 2 to the cutting blade 31, where it is cut to a suitable size. The first pressure roller 6 and the second pressure roller 7 eliminate wrinkles on the flexible material, and the limiting mechanism 4 adjusts the position of the flexible material, improving the accuracy of cutting the flexible material.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
