Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, and in particular to a dust removal device for a mobile paper product processing workshop. Background Technology

[0002] In the paper processing industry, processes such as cutting and polishing continuously generate large amounts of paper scraps, dust, and other pollutants during workshop production. These pollutants, suspended in the air, not only seriously threaten the respiratory health of workers and increase the risk of occupational diseases such as pneumoconiosis, but also cause product defects and reduce yield rates by adhering to the surface of paper products. Therefore, efficient dust removal equipment has become an essential facility in paper processing workshops. Existing dust removal devices in paper processing workshops commonly include fixed central dust collection systems and small stand-alone dust collection devices. Fixed central dust collection systems consist of a large central dust collection unit, a fixed pipeline network, and dust collection hoods distributed throughout the workshop. The main unit's high-powered fan creates negative pressure, and the pollutants collected by each dust collection hood are transported through the pipeline network to the dust collection unit for filtration. Small stand-alone dust collection devices consist of a dust collection box, a built-in fan, a suction hose, and a suction head. The fan creates negative pressure within the box, and the surrounding pollutants are adsorbed through the suction hose and suction head. Both rely on filters to intercept and filter pollutants.

[0003] Existing dust collection systems in paper product processing workshops mostly employ fixed dust collection equipment. These devices typically consist of a large dust collection box, fixed ducts, and suction ports. A fan creates negative pressure within the dust collection box, and the suction from the suction ports draws dust and paper scraps into the box, where they are then filtered through a filter. However, this type of fixed dust collection system has several drawbacks. The filter is easily clogged by paper scraps during use, and cleaning is inconvenient, often requiring manual disassembly and cleaning, which is time-consuming, labor-intensive, and can lead to equipment downtime, impacting production efficiency. To address this technical problem, this application proposes a mobile dust collection device for paper product processing workshops. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mobile dust removal device for paper product processing workshops. Activating the electric push rod drives the slider to move in the guide groove. The gear on the connecting rod meshes with the toothed plate to drive its rotation. The cleaning brush cleans the surface of the filter screen to prevent clogging and affect suction. Rotating the adjusting screw drives the fixed block to move, allowing it to disengage from the fixing groove of the fixing component for easy replacement and improved paper scrap removal effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A mobile dust removal device for a paper product processing workshop includes a base, a dust collection box fixedly connected to the top of the base, a telescopic pipe fixedly connected to the top of the dust collection box, a suction head fixedly connected to the other end of the telescopic pipe, a suction brush inside the suction head, a connecting plate on the outer wall of the suction head, a fixing member fixedly connected to the outer wall of the connecting plate, the fixing member being connected to the inside of the suction head via a disassembly assembly, a snap-fit ​​post fixedly connected to the bottom of the connecting plate, the bottom end of the snap-fit ​​post being located inside the suction brush, a filter screen on the inner wall of the dust collection box, and a cleaning assembly on the surface of the filter screen.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 2-4 This utility model provides an embodiment of a mobile dust removal device for a paper product processing workshop, comprising a base 1, a dust collection box 2 fixedly connected to the top of the base 1, a telescopic pipe 4 fixedly connected to the top of the dust collection box 2, a suction head 3 fixedly connected to the other end of the telescopic pipe 4, a suction brush 9 disposed inside the suction head 3, a connecting plate 11 disposed on the outer wall of the suction head 3, a fixing member 14 fixedly connected to the outer wall of the connecting plate 11, a fixing block 15 slidably connected inside the suction head 3, a limit block 16 fixedly connected to the outer wall of the fixing block 15, the limit block 16 slidably connected inside the suction head 3, and an adjusting screw 12 threadedly connected inside the fixing block 15. The screw 12 is rotatably connected to the inside of the vacuum head 3. The outer wall of the fixing part 14 is provided with a fixing groove. The front end of the fixing block 15 is set inside the fixing groove. The bottom of the connecting plate 11 is fixedly connected to the snap-fit ​​post 10. The bottom end of the snap-fit ​​post 10 is set inside the vacuum brush 9. The inner wall of the dust collection box 2 is provided with a filter screen 18. The surface of the filter screen 18 is provided with a cleaning brush 19. The outer wall of the dust collection box 2 is fixedly connected with a ventilation duct 5. The right end of the ventilation duct 5 is fixedly connected with a blower box 7. The bottom of the blower box 7 is fixedly connected to the top of the base 1. The top of the blower box 7 is fixedly connected with a push handle 6. The bottom of the base 1 is provided with a roller 8. The outer wall of the vacuum head 3 is fixedly connected with a handle 13.

[0027] Specifically, when the vacuum cleaner is working, the blower 7 starts operating, creating a negative pressure environment inside the dust collection box 2 by drawing air. Under the action of pressure difference, a strong suction is generated at the vacuum head 3. The user holds the handle 13 on the vacuum head 3, which allows for flexible operation and cleaning of different corners. The vacuum brush 9 inside the vacuum head 3 can effectively trap large pieces of paper scraps, preventing them from entering the telescopic pipe 4 and filter 18, thus avoiding blockages and ensuring smooth vacuuming. When the vacuum brush 9 needs to be replaced, it can be replaced by rotating the adjusting screw. 12. The fixed block 15 connected to it moves linearly inside the vacuum head 3 under the constraint of the limiting block 16 until it disengages from the fixing groove of the fixing member 14, releasing the restriction on the fixing member 14. Then, the connecting plate 11 is lifted so that the locking post 10 disengages from the vacuum brush 9, thus completing the disassembly and replacement of the vacuum brush 9, thereby maintaining its efficient ability to remove paper scraps. In addition, the push handle 6 and rollers 8 equipped with the device make it easy for users to push the device to move, meeting the needs of different cleaning scenarios and greatly improving the flexibility and convenience of use.

[0028] Reference Figure 1 , Figure 5 and Figure 6The filter screen 18 is provided with a cleaning brush 19, and a connecting rod 20 is fixedly connected inside the cleaning brush 19. A gear 23 is fixedly connected to the outer wall of the connecting rod 20. A toothed plate 21 is provided on the inner wall of the dust collection box 2. The outer wall of the gear 23 is meshed with the surface of the toothed plate 21. A slider 22 is rotatably connected to both ends of the connecting rod 20. A guide groove is opened inside the dust collection box 2. The slider 22 is slidably connected inside the guide groove. An electric push rod 17 is provided inside the dust collection box 2. The driving end of the electric push rod 17 is fixedly connected to the top of the left slider 22.

[0029] Specifically, after dust is sucked into the dust collection box 2, the filter screen 18 filters it, concentrating the dust inside the dust collection box 2. To prevent the filter screen 18 from becoming clogged and affecting the suction power, the electric push rod 17 can be activated to drive the slider 22 to move in the guide groove inside the dust collection box 2, thereby causing the connected rod 20 and the cleaning brush 19 to move synchronously. During the movement of the connecting rod 20, the gear 23 on it meshes with the toothed plate 21 on the inner wall of the dust collection box 2, driving the connecting rod 20 to rotate, which in turn drives the cleaning brush 19 to clean the surface of the filter screen 18 in all directions, ensuring stable suction power of the device.

[0030] Working principle: First, the operation of the bellows 7 creates negative pressure inside the dust collection box 2, thus generating suction at the suction head 3. Holding the handle 13 on the suction head 3 allows for flexible operation. The internal suction brush 9 traps large pieces of paper scraps, preventing blockage of the telescopic pipe 4 and filter 18. When the suction brush 9 needs replacement, rotating the adjusting screw 12 causes the fixing block 15 connected to it to move linearly inside the suction head 3 under the action of the limiting block 16, disengaging it from the fixing groove on the fixing member 14 and releasing the restriction on the fixing member 14. Then, lifting the connecting lever 11 disengages the locking pin 10 from inside the suction brush 9, allowing for easy replacement of the suction brush. Replacement of brush 9 improves the removal effect of paper scraps. Dust sucked into dust collection box 2 is filtered by filter screen 18 and concentrated inside dust collection box 2. To prevent filter screen 18 from clogging, electric push rod 17 can be activated to drive slider 22 to move in guide groove inside dust collection box 2. This causes connecting rod 20 and cleaning brush 19 connected to it to move as well. When connecting rod 20 moves, gear 23 on it meshes with toothed plate 21 on inner wall of dust collection box 2, causing connecting rod 20 to rotate. This causes cleaning brush 19 to clean the surface of filter screen 18, preventing the suction of the device from being affected. The push handle 6 and roller 8 enable the flexibility of the device.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
