Description

Technical Field

[0001] This invention relates to the field of carpet laser cutting equipment, specifically to an automatic positioning laser cutting device for carpets. Background Technology

[0002] In the carpet production and processing industry, traditional cutting methods often suffer from low efficiency and difficulty in adapting to the cutting needs of carpets of different thicknesses. Existing technologies use lasers to cut carpets. However, the fixed structure of the laser nozzle in existing laser cutting machines is complex, making replacement inconvenient and affecting work efficiency. Furthermore, because carpets have different shapes, it is difficult to adjust and fix the fixing components according to different carpet sizes, resulting in insufficient adaptability of the equipment.

[0003] According to patent document CN119525752A, a laser cutting machine for carpet cutting is disclosed, which includes a laser cutting machine body; a slide rail, the outer wall of which is fixedly connected to the inner wall of the laser cutting machine body; a sliding component, the bottom of which is slidably connected to the inner wall of the slide rail; a positioning component, the outer wall of which is slidably connected to the inner wall of the sliding component; and a transmission component, which is used to drive the sliding block to move, and the top of which is fixedly connected to the inner wall of the laser cutting machine body. In use, during carpet cutting, the operator can move the sliding frame to different positions as needed to cut different parts of the carpet. The top of the sliding frame is fixedly connected to the working frame, giving the equipment flexibility to cut in different positions, meeting the needs of large carpet cutting and fine cutting of specific areas, and improving the applicability of the equipment. However, while this solution achieves the requirement of fine cutting, it cannot fix and position the carpet at the cutting point for flat cutting, which is inconvenient during use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an automatic positioning laser cutting device for carpets, thereby solving the problems mentioned in the background section. The invention features a novel structure. In use, a servo motor drives a threaded column to rotate, which in turn pushes a filter box downwards via a transmission rod. As the filter box moves downwards, the height of the opening is adjusted to facilitate the extraction and filtration of gas generated during cutting. Furthermore, the descent of the filter box pushes positioning rollers to both ends. Under the pressure of the positioning rollers, the carpet at the cutting position is tightened, flattened, and positioned. The positioning rollers rotate in one direction, thus avoiding the impact of carpet shaking during cutting. Additionally, the height of the laser cutting head is adjusted by the descent of the filter box, enabling rapid height adjustment for quick operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic positioning laser cutting device for carpets, comprising a fixed base, a support base fixedly installed inside the fixed base, a drive motor fixedly installed on the side of the support base, a transmission belt mounted on the drive motor, a fixed frame movably installed on the top of the support base, a roller rotatably mounted on the fixed frame, a fixed box fixedly installed on the fixed base, a servo motor fixedly installed on the side of the fixed box, a threaded column mounted on the servo motor, a threaded seat rotatably mounted on the threaded column, a bushing rotatably mounted on the threaded seat, a positioning column welded to the top of the bushing, a fixed plate welded to the top of the positioning column, a slot opened on the inner wall of the top of the fixed box, and the positioning column movably installed inside the slot via the fixed plate.

[0006] Furthermore, a connecting lug is welded to the bottom of the threaded seat, a transmission rod is rotatably mounted on the connecting lug, a fixed lug is rotatably mounted on one end of the transmission rod, a filter box is fixed on the fixed lug, and a cutting assembly is fixedly mounted on the side of the filter box.

[0007] Furthermore, a fixing groove is opened on the side of the filter box, and a fixing block is slidably installed inside the fixing groove. The fixing block is installed inside the fixing groove by a tension mechanism. A connecting rod is rotatably installed on the fixing block, and a fixing column is rotatably installed at one end of the connecting rod. The fixing column is movably installed on the inner wall of the fixing box.

[0008] Furthermore, a one-way seat is fixed to one end of the fixed column, a positioning roller is rotatably mounted on the one-way seat, a limit groove is opened on the inner wall of the fixed box, a limit plate is welded to one end of the fixed column, and the fixed column is installed inside the limit groove through the limit plate.

[0009] Furthermore, an exhaust assembly is fixed inside the filter box. The exhaust assembly is installed inside the filter box via a fixing rod. An opening is formed on the side of the filter box. The cutting assembly includes a mounting plate. A mounting base is welded to one end of the mounting plate. A motor plate is welded to the mounting base. A DC motor is fixedly mounted on the motor plate. A threaded rod is fixed to the DC motor.

[0010] Furthermore, a threaded plate is movably mounted on the threaded rod, a clamping plate is movably mounted on one end of the threaded plate, a motor base is mounted between the clamping plates, a positioning groove is opened on the mounting base, the motor base is movably mounted inside the positioning groove, and a laser cutting head is fixedly mounted on the motor base.

[0011] Furthermore, a support frame is fixed to the side of the support base, and a movable plate is movably installed inside the support frame. The movable plate is installed inside the support frame through a reset mechanism, and a positioning frame is welded to one end of the movable plate. The positioning frame is fixedly installed on the side of the fixed frame.

[0012] Furthermore, the one-way seat includes a fixed cover, inside which a rotating disk is rotatably mounted. The rotating disk is fixed to the side of the positioning roller. A groove is formed on the rotating disk, and a movable block is movably mounted inside the groove. The movable block is mounted inside the groove via a fixed shaft. A repulsive magnet block is fixedly mounted between the movable block and the groove. A spring mechanism is fixedly mounted on one side of the movable block. A protrusion is fixed on the inner wall of the fixed cover, and the fixed cover is welded to one end of a fixed column.

[0013] Furthermore, a baffle is welded to the top of the motor base, a connecting block is fixed to the bottom of the threaded plate, a connecting groove is opened on the top of the clamping plate, the connecting block is installed inside the connecting groove by a support mechanism, a limit hole is opened on the side of the baffle, a limit post is movably installed inside the limit hole, and one end of the limit post is fixed to the side of the clamping plate.

[0014] Furthermore, the bottom of the clamping plate has a mounting hole, and a fixing bolt is rotatably mounted on the side of the motor base, with one end of the fixing bolt penetrating the motor base and installed inside the mounting hole.

[0015] The beneficial effects of this invention are: In this invention, a servo motor drives a threaded column to rotate, which in turn pushes a filter box downwards via a transmission rod. As the filter box moves downwards, the height of the opening is adjusted to facilitate the extraction and filtration of gas generated during cutting. Furthermore, the downward movement of the filter box pushes positioning rollers to both ends. Under the pressure of the positioning rollers, the carpet at the cutting position is tightened, flattened, and positioned. The positioning rollers rotate in one direction, thus avoiding the impact of carpet shaking during cutting. Additionally, the height of the laser cutting head is adjusted as the filter box descends, allowing for rapid height adjustment and quick use.

[0016] In this invention, after the filter box moves downward, it opens multiple points and directions to cooperate closely with the cutting point, which facilitates the filtration and discharge of the generated gas. During cutting, the two ends of the carpet are respectively limited and fixed by positioning rollers and rollers. The rollers push the fixing frame up and down according to the thickness of the carpet. Under the drive of the reset mechanism, the fixing frame pushes the rollers and squeezes and limits the top of the carpet.

[0017] This invention uses a threaded rod to move threaded plates synchronously to adjust the position of the laser cutting head. Later, after the clamping plates are moved to both sides, they lose their limiting and fixing effect on the baffle. The baffle drives the motor base and the laser cutting head to be disassembled, replaced, or repaired, thereby improving the efficiency of later work. This device is suitable for intelligent heat treatment production lines, automatic and semi-automatic electric arc and plasma arc welding machines, and other metal cutting and welding equipment.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 10 This invention provides a technical solution: an automatic positioning laser cutting device for carpets, comprising a fixed base 1, a support base 2 fixedly installed inside the fixed base 1, a drive motor 3 fixedly installed on the side of the support base 2, a conveyor belt 4 mounted on the drive motor 3, a fixed frame 5 movably installed on the top of the support base 2, a roller 6 rotatably mounted on the fixed frame 5, a fixed box 7 fixedly installed on the fixed base 1, a servo motor 8 fixedly installed on the side of the fixed box 7, a threaded post 13 mounted on the servo motor 8, and a rotatably mounted on the threaded post 13. A threaded seat 14 is provided, on which a bushing 15 is rotatably mounted. A positioning post 16 is welded to the top of the bushing 15, and a fixing plate 17 is welded to the top of the positioning post 16. A slot is opened on the inner wall of the top of the fixing box 7. The positioning post 16 is movably installed inside the slot through the fixing plate 17. When the threaded post 13 rotates later, the threaded seat 14 moves inward or outward at the same time. The threaded seat 14 rotates on the bushing 15. The bushing 15 and the positioning post 16 cooperate to limit the movement of the threaded seat 14, effectively avoiding the impact caused by the rotation of the threaded seat 14 causing the transmission rod 19 to swing.

[0021] In this embodiment, a connecting lug 18 is welded to the bottom of the threaded seat 14. A transmission rod 19 is rotatably mounted on the connecting lug 18. A fixing lug 20 is rotatably mounted on one end of the transmission rod 19. A filter box 44 is fixed on the fixing lug 20. A cutting assembly 22 is fixedly mounted on the side of the filter box 44.

The fixing block 43 is mounted inside the fixing groove 23 by a tension mechanism 24. A connecting rod 11 is rotatably mounted on the fixing block 43. A fixing post 10 is rotatably mounted on one end of the connecting rod 11. The fixing post 10 is movably mounted on the inner wall of the fixing box 7.

The fixed column 10 is installed inside the limit groove 9 through the limit plate 26. The tension mechanism 24 is a tension spring. When the filter box 44 moves downward, it pushes the connecting rod 11 to tilt. After the connecting rod 11 tilts, it drives the fixed block 43 to move inside the fixed groove 23. Later, when the filter box 44 loses the pressure on the connecting rod 11, the tension mechanism 24 drives the fixed block 43 and the connecting rod 11 to return to their original positions. When one end of the connecting rod 11 is pulled back to its original position, the positioning roller 12 moves inward and retracts at the same time.

[0022] In this embodiment, an exhaust assembly 21 is fixed inside the filter box 44. The exhaust assembly 21 includes an exhaust fan, and a filter adsorption plate is fixed to the side of the exhaust fan. The exhaust fan draws out the gas and other impurities generated during carpet cutting and filters them out, thereby effectively avoiding damage to the surrounding environment. The exhaust assembly 21 is installed inside the filter box 44 via a fixing rod 27. An opening 28 is provided on the side of the filter box 44. The cutting assembly 22 includes a mounting plate 29. A mounting base 30 is welded to one end of the mounting plate 29. A motor plate 31 is welded to the mounting base 30. A DC motor 32 is fixedly mounted on the motor plate 31. A threaded rod 33 is fixed to the DC motor 32. A threaded plate 34 is movably mounted on the threaded rod 33. A clamping plate 37 is movably mounted to one end of the threaded plate 34.

The movable plate 41 is installed inside the support frame 40 through a reset mechanism 42. A positioning frame 39 is welded to one end of the movable plate 41. The positioning frame 39 is fixedly installed on the side of the fixed frame 5. The reset mechanism 42 is a reset spring. The reset spring drives the movable plate 41 to move downward. When the movable plate 41 moves downward, it drives the fixed frame 5 to descend. The fixed frame 5 descends and squeezes the carpet. The fixed frame 5 can be adjusted by adaptively moving up and down to accommodate carpets of different thicknesses.

[0023] In this embodiment, the one-way seat 25 includes a fixed cover 45. A rotating disk 46 is rotatably mounted inside the fixed cover 45. The rotating disk 46 is fixed to the side of the positioning roller 12. A groove 50 is formed on the rotating disk 46. A movable block 48 is movably mounted inside the groove 50. The movable block 48 is mounted inside the groove 50 via a fixed shaft. A repulsive magnet block 51 is fixedly mounted between the movable block 48 and the groove 50. A spring mechanism 49 is fixedly mounted on one side of the movable block 48. A protrusion 47 is fixed on the inner wall of the fixed cover 45. The fixed cover 45 is welded to one end of the fixed column 10. A baffle 55 is welded to the top of the motor seat 35. A connecting block 54 is fixed to the bottom of the threaded plate 34. A connecting groove 52 is formed on the top of the clamping plate 37. The connecting block 54... The support mechanism 53 is installed inside the connecting groove 52. The side of the baffle 55 has a limit hole 56. A limit post is movably installed inside the limit hole 56. One end of the limit post is fixed to the side of the clamping plate 37. The bottom of the clamping plate 37 has an installation hole. A fixing bolt 57 is rotatably installed on the side of the motor base 35. One end of the fixing bolt 57 passes through the motor base 35 and is installed inside the installation hole. Both the support mechanism 53 and the elastic mechanism 49 are springs. Under the push of the support mechanism 53, the clamping plate 37 is always close to the baffle 55. The limit post on the clamping plate 37 enters the limit hole 56 to realize the quick limit fixation of the motor base 35. Later, the threaded plate 34 and the motor base 35 are fixedly connected by the fixing bolt 57, which facilitates the quick disassembly and replacement of the motor base 35.

[0024] Working principle: In use, one end of the carpet is installed on the top of the conveyor belt 4. As the drive roller on the drive motor 3 moves the conveyor belt 4, the top of the carpet is carried by the conveyor belt 4 to the bottom of the roller 6. With the support of the carpet, the roller 6 moves the fixing frame 5 upward. After the fixing frame 5 moves upward, the movable plate 41 moves upward, completing the pulling deformation of the reset mechanism 42. The fixing frame 5 can be adjusted at different distances through the cooperation of the movable plate 41 and the reset mechanism 42. After the fixing frame 5 moves upward, the pulling force generated by the reset mechanism 42 causes the fixing frame 5 to press and limit the carpet through the roller 6. One end of the moving carpet on the conveyor belt 4 is separated from the conveyor belt, but the top of the carpet is in contact with the roller 6. The roller 6 extends the carpet's walking distance. As the conveyor belt 4 continues to rotate, it pushes the carpet forward into the fixed box 7. Once the carpet is inside the fixed box 7, the servo motor 8 is activated, driving the threaded column 13 to rotate. After the threaded column 13 rotates, the threaded seat 14 moves inward or outward simultaneously. When the threaded seat 14 rotates, the bushing 15 and the positioning column 16 cooperate to limit and fix it. As the threaded seat 14 moves inward, the connecting lug 18 is pushed... One end of the transmission rod 19 tilts inward, and as the connecting rod 11 tilts, it pushes the filter box 44 downward. When the filter box 44 moves downward, it pushes the connecting rod 11 downward through the fixing block 43. When the connecting rod 11 moves downward, the fixing post 10 at one end pushes the positioning roller 12 to move to both sides. When the positioning roller 12 rotates, it rotates and moves on the carpet. When the positioning roller 12 rotates, the protrusion 47 pushes the movable block 48 to swing and rotate inside the groove 50. When the positioning roller 12 rotates, the elastic mechanism 49 and the repulsive magnet block 51 cooperate to push the movable block 48 to contact the protrusion 47. The movable block 48 is a convex... Block 47 implements a limiting stop, enabling the positioning roller 12 to move in one direction. When the positioning roller 12 rotates and moves back and forth, it tightens and squeezes the carpet. Under the squeezing of the positioning roller 12, the carpet at the cutting position is positioned and fixed. In addition, after the filter box 44 moves downward, it drives the cutting component 22 to move downward to the top of the carpet. The DC motor 32 is started to drive the threaded rod 33 to rotate. The threaded rod 33 drives the threaded plate 34 to move. The movement of the threaded plate 34 causes the motor base 35 to move linearly inside the positioning groove 36 to complete the cutting. During cutting, the laser cutting head 38 generates a laser beam to cut the carpet. During cutting, the exhaust fan inside the exhaust assembly 21 is activated, generating suction that draws the smoke generated at the cutting point through the opening 28 into the filter box 44. As the airflow is exhausted through the exhaust assembly 21, it is adsorbed and filtered by the internal filter adsorption assembly. After the filter box 44 is lowered, the opening 28 is brought closer to the top of the carpet, facilitating comprehensive adsorption and filtration of the generated gas. When the motor base 35 needs to be disassembled later, the fixing bolt 57 is rotated out from the inside of the motor base 35, the clamping plate 37 is no longer fixed, and the clamping plate 37 is moved to both sides. After the clamping plate 37 is moved to both sides, the limiting post is removed from the limiting hole 56, and the baffle 55 loses its limiting support. The motor base 35 is then removed downward from the inside of the positioning groove 36 for replacement. Later, the baffle 55 and the clamping plate 37 work together to facilitate quick positioning and installation, thereby facilitating the replacement and disassembly of the laser cutting head 38.
