Description

Technical Field

[0001] The invention relates to the field of sound-absorbing cotton board processing equipment, in particular to automobile composite sound-absorbing and environmentally friendly cotton board processing equipment. Background Art

[0002] With the rapid development of the automotive industry, consumers are increasingly demanding greater interior comfort. In-car noise control has become a key indicator of vehicle quality. As a key sound insulation and noise reduction material, the quality and performance of automotive composite sound-absorbing eco-friendly cotton panels have a crucial impact on the in-car acoustic environment.

[0003] Traditional automotive composite sound-absorbing, environmentally friendly cotton panels face numerous challenges during processing. The panels' securing and unfolding have traditionally relied on manual labor, a process that is not only inefficient but also difficult to ensure they are laid evenly and tightly on the processing table. This can lead to displacement and deformation during subsequent cutting, severely impacting cutting precision and product quality. For example, in some small automotive parts processing plants, manual securing and unfolding of the panels can lead to significant dimensional variations between batches due to varying worker techniques, resulting in high scrap rates.

[0004] At the same time, existing processing equipment lacks sufficient adaptability to handle cotton boards of varying materials and thicknesses. When encountering soft or thin cotton boards, excessive pulling force can easily damage them. Meanwhile, stiffer cotton boards are difficult to fully straighten and tighten, failing to meet processing requirements. This forces companies to frequently change processing techniques or equipment for different types of cotton boards during production, increasing production costs and lead times.

[0005] Furthermore, during the manufacturing, transportation, and storage processes of the cotton panels, a certain amount of stress accumulates within them. During subsequent cutting and processing, these stresses are concentrated and released, often causing deformation, microcracks, and other defects within the cotton panels. This not only reduces the fatigue resistance and durability of the sound-absorbing panels, but also makes their internal structure uneven, severely impacting their sound absorption and failing to provide an ideal soundproofing environment within the vehicle. Most processing equipment currently on the market fails to effectively address this critical issue of stress release within the cotton panels. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the present invention provides a processing equipment for automobile composite sound-absorbing and environmentally friendly cotton boards, which solves the problems of low efficiency of manual fixing and unfolding, easy damage to the cotton boards, and difficulty in releasing internal stress of the cotton boards resulting in poor product quality during the processing of automobile composite sound-absorbing and environmentally friendly cotton boards, thereby improving processing accuracy and product performance.

[0017] 3. This invention uses a worm to drive the rotating column.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: Please see the attached Figure 1 -Attached Figure 5 The embodiment of the present invention provides a processing device for automobile composite sound-absorbing environmentally friendly cotton board, such as Figure 1As shown, it includes a processing table 1, which serves as the basic bearing structure of the entire equipment and provides a platform for installation and operation of other components. Y-axis motion modules 2 are fixedly installed on both sides of its top. The Y-axis motion module 2 is composed of components such as a motor, a lead screw, and a guide rail. The lead screw is driven by the motor to rotate, driving the drive end slide to make a linear motion in the front and back direction (Y-axis direction) along the guide rail. The top of the drive end slide of the Y-axis motion module 2 is fixedly installed on both sides of the bottom end of the gantry 3, so that the gantry 3 can move stably in the Y-axis direction, providing a forward and backward movement foundation for the cutting device subsequently installed on the gantry 3. The gantry 3 is a "door" shaped structure with high strength and stability. An X-axis motion module 4 is fixedly installed on its front side. The X-axis motion module 4 is also composed of a motor, a lead screw, The Z-axis motion module 5 is fixedly installed on the driving end slide of the X-axis motion module 4. The Z-axis motion module 5 is also based on the principles of motor, lead screw and guide rail, and can control the movement of the driving end slide in the up and down direction (Z-axis direction). The Z-axis motion module 5 is fixedly installed on the driving end slide. The vibrating knife cutter 6 is used to cut the cotton board with a high-frequency vibrating tool, and cooperates with the X-axis motion module 4 to control its left and right movement, the Y-axis motion module 2 to control its front and back movement, and the Z-axis motion module 5 to control the up and down movement of the tool. It can accurately cut the cotton board into the required shape, greatly improving the cutting accuracy and processing efficiency, and meeting diverse processing needs.

[0022] Straight slots 7 are provided on both sides of the upper surface of the processing table 1. The straight slots 7 are arranged along the length direction of the processing table 1, and movable blocks 9 are movably installed inside them. The movable blocks 9 can slide in the straight slots 7 along the direction of the straight slots 7 to support and fix the cotton board to be processed. In this embodiment, guide rods 8 are fixedly installed on both sides of the interior of the straight slots 7. The guide rods 8 extend along the length direction of the straight slots 7 and are fixed on the groove wall of the straight slots 7. The outer diameters of the guide rods 8 are movably installed on both sides of the interior of the movable blocks 9 on the corresponding sides. The guide rods 8 play a limiting and guiding role on the movable blocks 9, ensuring that the movable blocks 9 can only make linear motion along the direction of the straight slots 7 during the movement, thereby ensuring the stability of the movement of the movable blocks 9, and thus ensuring the stability and accuracy of subsequent operations on the cotton board.

[0023] Furthermore, a mounting frame 10 is fixedly installed on the outer side of the top of the movable block 9. The mounting frame 10 is an "L"-shaped structure, one end of which is fixed to the outer side of the top of the movable block 9 to provide an installation position for the telescopic cylinder 11. A telescopic cylinder 11 is fixedly installed on the middle part of the top of the mounting frame 10. The telescopic cylinder 11 is fixed to the mounting frame 10 by bolts and other connecting parts. A pressure plate 12 is fixedly installed on the driving end of the telescopic cylinder 11. When the telescopic cylinder 11 is started, its driving end extends or retracts, driving the pressure plate 12 to move up and down. During the processing, the cotton board to be processed is first placed on the surface of the processing table 1, and the two sides of the cotton board are placed on the movable block 9. Then the telescopic cylinder 11 is started, and the pressure plate 12 is driven down by the telescopic cylinder 11. The pressure plate 12 cooperates with the movable block 9 to clamp the two ends of the cotton board to ensure that the cotton board will not be displaced during subsequent processing, thereby improving the processing accuracy.

[0024] Furthermore, a first clamping plate 22 is movably installed on the middle outer diameter of the short shaft 20, and the first clamping plate 22 can rotate at a certain angle around the middle of the short shaft 20. The inner ends of the first clamping plate 22 are connected to the outer sides of the driven bevel gear 21 on the corresponding side through a clamping spring 23. One end of the clamping spring 23 is fixed to the inner end of the first clamping plate 22, and the other end is fixed to the outer side of the driven bevel gear 21. When the driven bevel gear 21 rotates, the clamping spring 23 is driven to rotate together, and the clamping spring 23 drives the first clamping plate 22 to rotate. A second clamping plate 24 is fixedly installed on the outer outer diameter of the short shaft 20. The second clamping plate 24 is fixedly connected to the short shaft 20 and rotates synchronously. A number of round head grooves 25 are provided on the outer ends of the first clamping plate 22, and a number of round head grooves 25 are fixedly installed on the inner ends of the second clamping plate 24. The round-headed block 26 and the ends of the round-headed block 26 extend to the inside of the round-headed groove 25 on the corresponding side. When the second clamping plate 24 drives the first clamping plate 22 to rotate along with the clamping spring 23, the round-headed block 26 cooperates and moves in the round-headed groove 25. When the clamped cotton board is pulled and expanded to the extreme position, the short shaft 20 and the threaded rod 19 will stop rotating. The driven bevel gear 21 inside the short shaft 20 will compress the clamping spring 23 when rotating, causing the round-headed block 26 and the round-headed groove 25 to continuously disengage and engage, thereby preventing the short shaft 20 and the threaded rod 19 from rotating with the rotation of the driven bevel gear 21. When facing different cotton boards, it ensures that the cotton board is straightened and tightened while not being damaged by excessive pulling force, thereby protecting the integrity and quality of the cotton board.

[0025] The worm gear 15 is connected with the transmission shaft 14 by a key and rotates synchronously. A reduction motor 16 is fixedly installed on the middle part of the inner bottom of the processing table 1. The reduction motor 16 is fixed to the inner bottom of the processing table 1 by bolts, etc., to provide power for the entire transmission system. The driving end of the reduction motor 16 is fixedly mounted with a worm 17 and the two sides of the worm 17 are respectively meshed with the inner ends of the worm gears 15 on both sides. When the reduction motor 16 is started, the worm 17 is driven to rotate, and the rotating worm 17 drives the worm gears 15 and the transmission shaft 14 on both sides to rotate synchronously through the meshing transmission with the worm gear 15.

[0026] A driving bevel gear 18 is fixedly installed on the outer diameter of the other side of the transmission shaft 14. The driving bevel gear 18 is fixedly connected to the transmission shaft 14 and rotates with the transmission shaft 14. Threaded rods 19 are movably installed at both ends of the inner wall of the processing table 1. The threaded rods 19 are installed on the inner wall of the processing table 1 through bearings, etc., and can be rotated at the installation position. The inner ends of the threaded rods 19 are fixedly installed with short shafts 20, and the short shafts 20 are fixedly connected to the threaded rods 19. A driven bevel gear 21 is movably installed on the inner outer diameter of the short shaft 20, and the inner ends of the driven bevel gears 21 are aligned with one side of the corresponding driving bevel gear 18. They are meshed and connected. When the active bevel gear 18 rotates with the transmission shaft 14, it drives the driven bevel gears 21 and the short shaft 20 on both sides to rotate through the meshing transmission with the driven bevel gear 21, and then drives the threaded rods 19 on both sides to rotate. When the threaded rods 19 rotate, the limiting effect of the guide rod 8 will drive the sliders 27 and the movable blocks 9 on both sides to move outward synchronously, thereby pulling the clamped cotton board outward and unfolding it, so that the cotton board is completely stretched and flattened on the surface of the processing table 1, ensuring that the cotton board remains stable during the processing, improving the processing accuracy, and the process does not require manual operation, which greatly improves the processing efficiency.

[0027] Furthermore, a rectangular groove is provided in the middle of the upper surface of the processing table 1, and a lifting block 28 is movably installed in the rectangular groove. The rectangular groove limits the lifting block 28, so that it can only make linear motion in the vertical direction. A shaking plate 29 is fixedly installed on the top of the lifting block 28. When the lifting block 28 moves in the vertical direction, the shaking plate 29 is driven to move together. A rotating column 30 is fixedly installed on the top of the worm 17 through a connecting shaft, and the end of the rotating column 30 extends to the inside of the lifting block 28. The rotating column 30 rotates synchronously with the worm 17. A bidirectional spiral groove 31 is provided on the outer diameter of the rotating column 30, and a round head pin 32 is fixedly installed on one side of the inner bottom of the lifting block 28, and the end of the round head pin 32 is movably arranged in the inside of the bidirectional spiral groove 31. When the worm 17 rotates, it drives the rotating column 30 on the top to rotate. When the rotating column 30 rotates, it will drive the bidirectional spiral groove 31 on the outer diameter to rotate, and the rotating bidirectional spiral groove 31 will The round-head pin 32 is driven to move inside it, and the limiting effect of the rectangular groove is used to drive the round-head pin 32 and the lifting block 28 to perform linear motion in the vertical direction. The bidirectional spiral groove 31 is composed of two spiral grooves with opposite spiral directions but connected end to end. When the round-head pin 32 moves to the tail of one of the spiral grooves, it will enter the head of the other spiral groove and change the direction of movement. As the rotating column 30 continues to rotate, the lifting block 28 is driven to perform rapid up and down reciprocating motion, thereby driving the top shaking plate 29 to follow the movement. The shaking plate 29 that continues to move up and down will slap the outer surface of the cotton board to release its internal stress, which can effectively avoid deformation, microcracks and poor stability caused by stress concentration in the subsequent cutting process, improve the fatigue resistance and durability of the sound-absorbing panel, and make the internal structure of the sound-absorbing panel more uniform and dense, thereby improving its overall physical properties and sound absorption effect, and providing a better sound insulation and noise reduction environment for the car.

[0028] Furthermore, a control panel 33 is fixedly installed at the front end of the processing table 1. The control panel 33 integrates various control buttons, display screens and other components. The operator can conveniently start and stop the reduction motor 16, the telescopic cylinder 11, the vibration knife cutting machine 6, and control the movement of the X-axis motion module 4, the Y-axis motion module 2, and the Z-axis motion module 5 through the control panel 33, thereby controlling the equipment as a whole and reducing the labor intensity and operation difficulty of the operator.

[0029] Working principle: First, place the cotton board to be processed on the surface of the processing table 1, and place both sides of the cotton board on the movable block 9. Then start the telescopic cylinder 11, and drive the pressure plate 12 to descend through the telescopic cylinder 11. The pressure plate 12 cooperates with the movable block 9 to clamp the two ends of the cotton board. After completion, start the reduction motor 16, and drive the worm 17 to rotate through the reduction motor 16. The rotating worm 17 drives the worm gear 15 and the transmission shaft 14 on both sides to rotate synchronously through meshing transmission. The transmission shaft 14 drives the active bevel gear 18 on the outer diameter to rotate. The rotating active bevel gear 18 then drives the driven bevel gears 21 and the short shaft 20 on both sides to rotate through meshing transmission, thereby driving the threaded rods 19 on both sides to rotate. When the threaded rod 19 rotates, the limiting effect of the guide rod 8 is used to drive the sliders on both sides. 27 and the movable block 9 move outward synchronously, thereby pulling the clamped cotton board outward and unfolding it, so that the cotton board is completely tightened and flattened on the surface of the processing table 1. In addition, when the driven bevel gear 21 rotates, it does not directly drive the short shaft 20 to rotate, but drives the clamping spring 23 to rotate, and then the clamping spring 23 drives the second clamping plate 24 to rotate. The second clamping plate 24 uses the round head groove 25 and the round head clamping block 26 to drive the first clamping plate 22 to rotate, thereby driving the short shaft 20 to rotate. When the clamped cotton board is pulled and unfolded to the limit position, the short shaft 20 and the threaded rod 19 will stop rotating. The driven bevel gear 21 inside the short shaft 20 will compress the clamping spring 23 when rotating, causing the round head clamping block 26 and the round head groove 25 to continuously disengage and engage, thereby avoiding The short shaft 20 and the threaded rod 19 rotate with the rotation of the driven bevel gear 21. When facing different cotton boards, it is ensured that the cotton boards are straightened and tightened while not causing damage to the cotton boards due to excessive pulling force. At the same time, when the worm 17 rotates, it also drives the rotating column 30 on the top to rotate. When the rotating column 30 rotates, it drives the bidirectional spiral groove 31 on the outer diameter to rotate. The rotating bidirectional spiral groove 31 drives the round head pin 32 to move inside it, and utilizes the limiting effect of the rectangular groove to drive the round head pin 32 and the lifting block 28 to make a vertical linear motion. The bidirectional spiral groove 31 is composed of two spiral grooves with opposite spiral directions but connected end to end. When the round head pin 32 moves to the tail of one of the spiral grooves, it enters the head of the other spiral groove and changes the direction of movement. As the rotating column 30 continues to rotate, the lifting block 28 is driven to make rapid up and down reciprocating motion, thereby driving the top shaking plate 29 to follow the motion. The shaking plate 29 that continues to move up and down will slap the outer surface of the cotton board to release its internal stress, which can effectively avoid deformation, microcracks and poor stability caused by stress concentration in the subsequent cutting process, improve the fatigue resistance and durability of the sound-absorbing panel, and make the internal structure of the sound-absorbing panel more uniform and dense, thereby improving its overall physical properties and sound absorption effect, providing a better sound insulation and noise reduction environment for the car, and finally start the vibrating knife cutting machine 6, control its left and right movement through the X-axis motion module 4, control its front and back movement through the Y-axis motion module 2, and control the up and down movement of the tool through the Z-axis motion module 5 to cut the cotton board into the required shape.
