Description

Technical Field

[0001] This utility model belongs to the technical field of automotive seat cover fabric processing equipment, specifically relating to an automotive seat cover fabric cutting and dust extraction device. Background Technology

[0002] Currently, with the continuous development of the automotive manufacturing industry, the production of car seat covers places higher demands on the precision and cleanliness of fabric cutting. Existing car seat cover fabrics are mostly cut manually or semi-automatically. These methods often have the following prominent problems: First, traditional cutting processes rely heavily on mechanical tools, which can easily lead to deviations in cutting precision and are not well-suited for cutting complex curves. While laser cutting technology can significantly improve cutting precision and production efficiency, in actual use, it generates a large amount of fine particles and dust that easily adhere to the fabric surface, affecting the quality of subsequent processes and even posing a threat to the health of operators.

[0003] To address the issue of smoke and particulate pollution generated during laser cutting, some companies have introduced localized ventilation or simple dust collection measures. However, due to insufficient coordination between the dust collection system and the cutting head, the dust collection effect is limited, and a considerable amount of dust and particles still cannot be collected in a timely and effective manner, resulting in a large amount of fine impurities remaining around the equipment and in the production environment. In addition, the filtration and cleaning processes of existing dust collection devices are mostly manually disassembled, which is cumbersome and inconvenient, affecting production efficiency and the continuous operation of equipment. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a car seat cover fabric cutting and vacuuming device that can achieve simultaneous laser cutting and efficient vacuuming, has excellent filtration effect, and is easy to clean.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A vacuuming device for cutting car seat cover fabric includes a base and a laser cutting head. The upper surface of the base is fixed with two transverse guide rails, and a movable frame that can move left and right is installed between the two guide rails. A traveling mechanism that can move back and forth is installed on the movable frame. A longitudinal rack is fixed on the movable frame. The traveling mechanism includes a support plate. A sliding clip is fixed on the left side of the support plate and mounted on the movable frame. A traveling motor is also fixed on the left side of the support plate. A gear that meshes with the rack is fixed on the output shaft at the lower end of the traveling motor. The right side of the support plate is fixed with a suction component and a dust collection component from top to bottom. A filter box is detachably installed between the suction component and the dust collection component. The filter box provides ventilation connection between the suction component and the dust collection component, and a filter component is installed inside the filter box. The laser cutting head is fixed to the lower right corner of the support plate, and the dust suction port at the lower end of the dust collection component is flush with the lower end of the laser cutting head.

[0006] Furthermore, the suction assembly includes a first fixing plate fixed to the support plate, and a plurality of fans are fixed on the first fixing plate.

[0007] Furthermore, the dust collection assembly includes a second fixing plate fixed to the support plate, and two dust collection pipes, one in front and one in back, are fixed on the second fixing plate. The two dust collection pipes are respectively arranged on the front and back sides of the laser cutting head.

[0008] Furthermore, the front and rear edges of the opposite sides of the first and second fixed plates are provided with baffles to limit the filter box in the front and rear directions, and a baffle to block the filter box is rotatably installed on the right side of the first fixed plate.

[0009] Furthermore, the filter box has an opening at the top, and an air inlet pipe is fixed at the bottom of the filter box corresponding to the dust suction pipe. A dispersion plate is installed at the upper end of the air inlet pipe. The filter box has slots on both the front and back sides, and a handle is fixed on the right side of the filter box.

[0010] Furthermore, the filter assembly includes a frame and a filter plate installed inside the frame. A pressure frame is fitted inside the frame to press and fix the filter plate. Both ends of the frame are fixed with a locking structure that engages with the front and rear side walls of the filter box.

[0011] Furthermore, the locking structure includes a buckle plate fixed to the frame and a pressing plate fixed to the buckle plate. The pressing plate extends toward the middle of the filter box, and a protruding buckle platform is fixed on the side of the buckle plate away from the pressing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention achieves precise and automated movement of the laser cutting head by setting a transverse guide rail, a moving frame, and a walking mechanism on the base. This effectively improves the cutting accuracy of automotive seat cover fabrics, meets the processing needs of complex curves and various fabric specifications, and solves the problems of low precision and poor flexibility in traditional cutting processes.

[0013] This invention features a high-efficiency dust collection component installed below the laser cutting head and on both sides of its working area. This component can simultaneously collect a large number of fine particles and dust generated by laser cutting during the cutting process, preventing dust from polluting the fabric surface and the workshop environment. This overcomes the problems of poor dust collection system fit with the cutting head and unsatisfactory dust collection effect in the prior art.

[0014] This utility model adopts a modular filter box structure, with multi-stage filtration components inside the filter box, which can efficiently filter and collect dust and particulate matter. A fan creates a continuous negative pressure to ensure that the exhaust air is clean, which significantly improves the air quality at the work site and the safety of equipment operation, and solves the problems of low filtration efficiency and high residual dust in existing dust collection devices.

[0015] This utility model features a handle that is easy to disassemble, a quick-release buckle groove, and an easy-to-operate limiting device, which greatly facilitates the replacement and cleaning of the filter box and filter plate, improves the convenience of daily maintenance and the continuous operating efficiency of the equipment, and solves the problems of complex cleaning and inconvenient maintenance in traditional structures.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. Example

[0020] like Figure 1 , Figure 2 and Figure 4As shown, a vacuuming device for cutting car seat cover fabric includes a base 1 and a laser cutting head 5. The base 1 provides a stable support foundation for the device. Two transverse guide rails 2 are fixed to the upper surface of the base 1, supporting and guiding a movable frame 3 to slide smoothly on the base 1. A movable frame 3, capable of moving left and right, is installed between the two guide rails 2. The movable frame 3 moves horizontally under the constraint of the guide rails 2, thereby driving a traveling mechanism 4 to achieve large-area coverage cutting. A traveling mechanism 4, capable of moving back and forth, is installed on the movable frame 3. The traveling mechanism 4, through a precise driving system, ensures that the laser cutting head 5 can move accurately and smoothly along the longitudinal direction, improving cutting efficiency and precision. A longitudinal rack 3 is fixed on the movable frame 3. 1. The rack 31 is used to mesh with the gear 41 of the walking mechanism 4 to realize power transmission. The walking mechanism 4 includes a support plate 43, which serves as a load-bearing platform and provides mounting bases for major components such as the laser cutting head 5, the suction assembly 44, the dust collection assembly 46, and the filter box 45, ensuring the coordinated operation and stability of each component. A sliding clamp is fixed on the left side of the support plate 43 and mounted on the moving frame 3. The sliding clamp mechanism achieves a reliable connection between the support plate 43 and the moving frame 3 through a precise matching structure, preventing shaking or displacement during movement and improving the overall operational stability of the device. A walking motor 42 is also fixed on the left side of the support plate 43. The walking motor 42 serves as the power source for the movement of the device and has high responsiveness and stability. The walking motor 42 has a gear 41 fixed on its output shaft at the lower end, which meshes with the rack 31. The rotation of the gear 41 enables the walking mechanism 4 to move linearly on the moving frame 3, driving the support plate 43 and all its components to move synchronously, completing the automated cutting operation. The right side of the support plate 43 has a suction assembly 44 and a dust collection assembly 46 fixed from top to bottom. The suction assembly 44 provides negative pressure to the filter box 45 through multiple fans 442, while the dust collection assembly 46 efficiently collects the particles and dust generated during the laser cutting process. A filter box 45 is detachably installed between the suction assembly 44 and the dust collection assembly 46. The filter box 45 adopts a modular structure design, facilitating later maintenance and cleaning. The suction assembly 44 and the dust collection assembly 46 are connected for ventilation to ensure unobstructed airflow and achieve efficient separation of smoke and dust from the air. The filter assembly 47 is installed inside the filter box 45. The filter assembly 47 is used to efficiently filter particulate matter and smoke, improve air cleanliness, and protect equipment and environmental safety. The laser cutting head 5 is fixed to the lower right corner of the support plate 43. The laser cutting head 5 can automatically move and cut along the working surface of the base 1 according to process requirements, with high cutting accuracy and stable operation. The dust collection port at the lower end of the dust collection assembly 46 is flush with the lower end of the laser cutting head 5. The dust collection port is close to the cutting area and can suck in the fine particles and smoke generated during the cutting process in the first time, preventing pollution from spreading and effectively improving the cutting quality and environmental hygiene level.

[0021] like Figure 3 As shown, the suction assembly 44 includes a first fixing plate 441 fixed on the support plate 43. The first fixing plate 441 securely mounts the fan 442 to the surface of the support plate 43 by a high-strength fastening method, ensuring that the suction assembly 44 is structurally stable and noiseless during operation. Several fans 442 are fixed on the first fixing plate 441. The multiple fans 442 are evenly distributed and arranged to form a continuous and strong suction force, which creates sufficient negative pressure on the filter box 45 to efficiently suck in the dust and particles generated during cutting, ensuring the efficiency and reliability of the entire dust collection process.

[0022] like Figure 3 As shown, the dust collection component 46 includes a second fixing plate 461 fixed on the support plate 43. The second fixing plate 461 is connected to the support plate 43 through a high-precision positioning and fastening device, which improves the collaborative working efficiency of the dust collection component 46 and the suction component 44. Two suction pipes 462 are fixed on the second fixing plate 461. The two suction pipes 462 are respectively arranged on the front and rear sides of the laser cutting head 5. The suction pipes 462 are made of high temperature and corrosion resistant materials, which can adapt to the special working conditions in the laser cutting environment. The suction pipes 462 arranged in the front and rear can collect dust and smoke generated by cutting from multiple angles and all directions, improving the dust collection coverage.

[0023] like Figure 3 As shown, the front and rear edges of the opposite sides of the first fixing plate 441 and the second fixing plate 461 are provided with baffles to limit the front and rear directions of the filter box 45. The baffles prevent the filter box 45 from shifting in the front and rear directions during operation by physically limiting it, thus ensuring the airtightness of the airflow channel and the dust collection effect. A baffle 443 is rotatably installed on the right side of the first fixing plate 441 to block the filter box 45. The baffle 443 is connected by a rotating shaft, which makes it easy for the user to operate when replacing the filter box 45 and ensures the convenience and firmness of the filter box 45 installation.

[0024] like Figure 4 and Figure 5As shown, the filter box 45 has an opening at the top, which facilitates the disassembly and cleaning of the filter assembly 47 by operators, improving maintenance convenience. Air inlet pipes 452 are fixed at positions on the lower side of the filter box 45 corresponding to the suction pipe 462. The air inlet pipes 452 and the suction pipe 462 are tightly connected, providing a dedicated channel for airflow to enter the filter box 45 from the cutting area. The structural design of the air inlet pipes 452 effectively disperses the sucked-in smoke and particles, preventing local blockage and improving the filtration effect. A dispersion plate 453 is installed at the upper end of the air inlet pipe 452, which disperses the high-speed airflow. The airflow is evenly distributed inside the filter box 45 to prevent damage to the filter plate 472 caused by local airflow impact, thereby improving the overall filtration efficiency and service life. The front and rear sides of the filter box 45 are provided with locking grooves 454, which are used to cooperate with the locking structure on the filter assembly 47 to achieve quick positioning and stable installation of the filter assembly 47, preventing shaking and displacement during operation. A handle 451 is fixed on the right side of the filter box 45. The handle 451 adopts an ergonomic design to facilitate the operator to lift and replace the filter box 45, improving the user-friendliness and convenience of the device.

[0025] like Figure 6 As shown, the filter assembly 47 includes a frame 471 and a filter plate 472 installed inside the frame 471. The frame 471 is made of high-strength, corrosion-resistant material to ensure that the structure is not easily deformed during long-term high-frequency cleaning. The filter plate 472 uses high-efficiency multi-layer filter material, which has high filtration accuracy for fine particles and dust, and extends the equipment maintenance cycle. The inner side of the frame 471 is fitted with a pressure frame 474 to press and fix the filter plate 472. The pressure frame 474 firmly presses the filter plate 472 through elastic or rigid fit to prevent loosening and dust leakage under high air volume conditions, thereby improving the reliability of the overall filter assembly. Both the front and rear ends of the frame 471 are fixed with a locking structure that snaps into the front and rear side walls of the filter box 45. The locking structure ensures that the filter assembly 47 and the filter box 45 fit tightly together, improving the sealing effect and filtration efficiency.

[0026] like Figure 6As shown, the locking structure includes a buckle plate 476 fixed to the frame 471 and a pressing plate 473 fixed to the buckle plate 476. The buckle plate 476 is made of high-strength elastic material or metal material to ensure the repeated opening and closing performance of the locking structure and improve the convenience and durability of component replacement. The pressing plate 473 extends to the middle of the filter box 45. The structural design of the pressing plate 473 makes it easy for the operator to press and release with one hand, improving the ease of operation of the device. A protruding buckle platform 475 is fixed on the side of the buckle plate 476 away from the pressing plate 473. The buckle platform 475 cooperates with the buckle groove 454 in the filter box 45 to achieve quick buckling during installation. During disassembly, the buckle platform 475 can be disengaged from the buckle groove 454 by pressing the pressing plate 473, which facilitates the replacement and cleaning of the filter plate 472 and ensures the long-term stable operation and efficient dust removal of the device. Example

[0027] See Figures 1-6 As shown in the figure, this embodiment discloses a fully automatic dust collection device suitable for large-scale cutting of automotive seat cover fabrics, which further improves cutting accuracy, environmental cleanliness and ease of operation.

[0028] In the actual working process, the car seat cover fabric to be cut is first neatly laid on the base 1. The base 1 adopts a thickened steel plate welded structure, which has good rigidity and stability. Anti-slip pads are provided at the four corners of the base 1 to ensure that the whole device does not shift when running at high speed. Two transverse guide rails 2 are fixed on the upper surface of the base 1. The guide rails 2 are high-precision linear guide rails, which, together with self-lubricating bearings, ensure that the moving frame 3 slides smoothly on them. Limit blocks are provided at both ends of the guide rails 2 to prevent the moving frame 3 from overtraveling and derailing.

[0029] The mobile frame 3 is made of lightweight alloy profiles, balancing rigidity and weight reduction. The mobile frame 3 achieves a wide range of left and right movements through four sets of guide sliders precisely engaged with the guide rails 2. The mobile frame 3 is equipped with a stroke detection device and an emergency stop button, which can immediately cut off the power supply to ensure safety in extreme situations. A traveling mechanism 4, capable of forward and backward movement, is integrated above the mobile frame 3. The traveling mechanism 4 consists of high-precision slide rails, a support plate 43, a stepping motor 42, and stroke limit sensors. The support plate 43 is securely connected to the mobile frame 3 via a sliding clamping structure. A longitudinal rack 31 is integrated on the support plate 43, and the rack 31 adopts a modular design for easy replacement and maintenance. A high-strength gear 41 is installed at the lower end of the output shaft of the traveling motor 42. The gear 41 precisely meshes with the rack 31. When the motor 42 is powered on, it drives the gear 41 to rotate, thereby causing the support plate 43 to move back and forth on the mobile frame 3, achieving precise positioning and path control of the laser cutting head 5.

[0030] The laser cutting head 5 is fixedly installed at the lower right corner of the support plate 43. The laser cutting head 5 is a special fabric laser cutting component with automatic focusing and power adjustment functions. It can adjust the cutting power according to different fabric types to ensure that the cut is flat and free of burrs. A cutting positioning laser indicator is provided below the laser cutting head 5 to assist in precise alignment.

[0031] During the cutting process, the laser cutting head 5 automatically cuts the fabric according to a preset trajectory. A large number of fine particles and dust generated during the process are collected in real time through the dust suction port at the lower end of the dust suction component 46, which is flush with the lower end of the laser cutting head 5. The dust suction component 46 is a high-vacuum dust suction mechanism, which integrates two dust suction pipes 462. The dust suction pipes 462 are distributed front and back, which can effectively cover the entire working area of ​​the cutting head 5 and improve the dust capture efficiency.

[0032] The suction pipe 462 evenly disperses the collected particulate matter and dust into the filter box 45 through the air inlet pipe 452. The filter box 45 adopts a fully sealed structure and the top cover adopts a quick-release buckle design for easy maintenance. A dispersion plate 453 is installed at the port of the air inlet pipe 452 to ensure that the high-speed airflow is evenly distributed and to prevent local damage to the filter plate 472.

[0033] The filter box 45 contains a high-efficiency multi-layer filter assembly 47. The filter assembly 47 includes a thickened metal frame 471, multi-layer high-efficiency filter plates 472, an internal pressure frame 474, and a locking structure. The locking structures at both ends of the filter assembly 47 work together with the buckle plate 476, the pressing plate 473, and the buckle platform 475 to ensure a tight fit between the filter assembly 47 and the filter box 45, preventing dust leakage. Ergonomic handles 451 are provided on both sides of the filter box 45 for easy disassembly and replacement.

[0034] The filtered clean air is discharged through multiple fans 442 on the first fixed plate 441 by the suction assembly 44. The fans 442 are silent high-speed axial flow fans, which ensure sufficient suction power and low noise. In order to prevent the equipment from overheating, the suction assembly 44 is equipped with a temperature sensor and an automatic overload protection module. When the fan is overloaded or the temperature is abnormal, the power is automatically cut off and an alarm is triggered to ensure the safety of the equipment.

[0035] After cutting and vacuuming, the operator can pull out the filter box 45 using the handle 451 on the right side of the filter box 45, release the limit by rotating the baffle 443, remove the filter assembly 47, and then press the pressing plate 473 to disengage the mounting plate 475 from the mounting groove 454, thereby successfully removing the filter plate 472. The filtered particles and dust can then be collected and cleaned for subsequent maintenance and environmental protection.

[0036] To prevent static electricity buildup during operation from causing sparks or reducing dust collection efficiency, static grounding wires are connected between the base 1 and the main metal components. A metal protective mesh layer is added inside the filter box 45 to prevent high-temperature particles from directly impacting the filter plate 472, further extending the service life of the equipment.

[0037] In this embodiment, under the coordinated control of the automated system, the entire device operates precisely and smoothly, ensuring both cutting accuracy and production efficiency. Furthermore, through efficient dust collection and multi-stage filtration throughout the process, the problem of dust particle pollution during laser cutting is completely solved, effectively improving the workshop environment and fabric product quality.

[0038] The working principle of this utility model is as follows: When cutting the car seat cover fabric, the fabric is placed on the working surface of the base 1. At this time, the movement of the moving frame 3 on the guide rail 2 and the movement of the walking mechanism 4 on the moving frame 3 drive the laser cutting head 5 to move and cut. When the walking mechanism 4 is walking, the walking motor 42 drives the gear 41 to rotate. The rotating gear 41 drives the support plate 43 to move the laser cutting head 5 by meshing with the rack 31. When the laser cutting head 5 is cutting, the fine particles and dust generated are sucked away by the suction pipe 462 and enter the inside of the filter box 45 through the air inlet pipe 452. At this time, the filter plate 472 inside the filter box 45 filters the particles and dust, and the filtered air is discharged to the outside through the fan 442. Finally, by rotating the baffle 443 upwards, the filter box 45 is removed, and the buckle plate 476 is bent by pressing the pressing plate 473, so that the buckle plate 475 is disengaged from the buckle groove 454. Finally, the filter plate 472 is removed, and the particles and dust filtered out in the filter box 45 can be cleaned.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
