Description

Technical Field

[0001] This utility model relates to the field of cleaning and dust removal devices, and in particular to a cleaning and dust removal device for paper feed rollers. Background Technology

[0002] In the production process of paper feed rollers, cleaning and dust removal are key steps to ensure their efficient operation. Over time, paper scraps, dust, and other impurities easily accumulate on the surface of the paper feed rollers. This not only affects production efficiency but can also lead to equipment damage and malfunctions. To effectively remove these contaminants, using a pneumatic dust brush device is an ideal solution. The pneumatic dust brush device uses high-speed airflow to blow off impurities from the surface of the paper feed rollers, and then cleans the surface of the paper feed rollers by rotating or vibrating the brush head. This can quickly remove dirt and avoid the influence of moisture on the paper feed rollers, thereby ensuring the stability and accuracy of the paper feed rollers in long-term use.

[0003] The pneumatic dust removal device mainly consists of the following core components: a pneumatic dust blowing system, a rotating brush head, a dust collection device, and a support structure. The pneumatic dust blowing system uses high-speed compressed air to remove dust, debris, and other contaminants from the surface of the paper feed rollers. The rotating brush head is made of soft bristles or rubber, which can flexibly adapt to different shapes of paper feed rollers and effectively remove attached dust and paper scraps. The dust collection device sucks in and collects the dust and debris removed by airflow to avoid secondary pollution. The support structure is used to support the entire device and maintain its stability and flexibility.

[0004] Traditional paper feed roller cleaning devices, such as airflow cleaning devices or simple brush cleaning devices, often suffer from incomplete cleaning. They struggle to thoroughly remove stubborn dirt and paper scraps from the surface of the paper feed rollers. Incomplete cleaning results in residual dust and paper scraps that negatively impact the working performance of the paper feed rollers, leading to increased equipment wear, decreased production efficiency, and even equipment malfunctions or downtime due to excessive dust accumulation. Furthermore, traditional cleaning devices often fail to fully clamp or secure the paper feed rollers, causing them to be violently thrown off or fall during the cleaning process. This not only causes secondary pollution but also allows unremoved dirt to accumulate in subsequent production, affecting the stability and operational precision of the paper feed rollers, thus impacting the quality and efficiency of the entire production process.

The connecting piece springs back under the action of the spring, causing the clamping plate to expand outward. This achieves the effect of expanding and clamping the paper feed roller, preventing it from falling off during cleaning and dust removal, causing secondary pollution, and affecting the quality and efficiency of the entire production process.

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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a cleaning and dust removal device for paper feed rollers, including a dust removal chamber 1. Multiple motors 2 are fixedly connected to the top of the dust removal chamber 1, and a cylindrical brush 3 is fixedly connected to the output end of each motor 2. Multiple dust blowing nozzles 4 are arranged inside the dust removal chamber 1. The cylindrical brushes 3 work in conjunction with the dust blowing nozzles 4 to clean and blow away dust. The dust blowing nozzles 4 use high-speed airflow to blow off most of the impurities on the surface of the paper feed rollers, while the cylindrical brushes 3 remove stubborn impurities adhering to the surface of the paper feed rollers, further improving the dust removal effect. A rotating assembly is arranged on the side wall of the dust removal chamber 1, including a fixed gear disc 5. The fixed gear disc 5 is arranged on the side wall of the dust removal chamber 1, and a motor 6 is fixedly connected to the bottom of the fixed gear disc 5. A rotating shaft is fixedly connected to the output end of the motor 6. A bushing 8 is rotatably connected to the outer wall of the rotating shaft 7. The bushing 8 is used to protect the fixed gear disk 5 and prevent the rotating shaft 7 from being damaged by long-term rotation, so as to make it rotate smoothly. The outer wall of the bushing 8 is fixedly connected to the inside of the fixed gear disk 5. A cross rotating component 9 is fixedly connected to one end of the rotating shaft 7. Multiple bushings 10 are fixedly connected inside the cross rotating component 9. A rotating shaft 11 is rotatably connected inside each bushing 10. A gear 12 is fixedly connected to the outer wall of the rotating shaft 11. The gear 12 meshes with the fixed gear disk 5. The fixed gear disk 5 rotates in cooperation with the gear 12, which further drives the material on it to rotate, avoiding cleaning dead corners and improving the cleaning efficiency of the paper feeding wheel. A clamping component is set inside the rotating shaft 11.

[0034] Reference Figure 4 and Figure 5The clamping assembly includes a fixing member 13, the outer wall of which is fixedly connected to the inside of a rotating shaft 11. The outer wall of the rotating shaft 11 is fixedly connected to the inside of each bushing 10. The outer wall of the rotating shaft 11 is fixedly connected to the inside of a gear 12. A pull rod 14 is slidably connected inside the fixing member 13. A hand-operated disc 19 is fixedly connected to the bottom of the pull rod 14. A spring 15 is sleeved on the outer wall of the pull rod 14. The spring 15 can not only be used to spring back the pulled-out pull rod 14, but also apply pressure to the clamping plate 18 through the connecting member 16 and the connecting block 17, providing pressure for outward clamping. One end of the spring 15 is fixedly connected to the side wall of the pull rod 14, and the other end of the spring 15 is fixedly connected to the upper surface of the fixing member 13. A connector 16 is fixedly connected to the top, and the bottom of the connector 16 is fixedly connected to the top of the pull rod 14. Multiple connecting blocks 17 are rotatably connected to the side wall of the connector 16. Each connecting block 17 is rotatably connected to the side wall of the connector 16. Multiple clamping plates 18 are provided on the side wall of the connector 16. Some clamping plates 18 are rotatably connected to the side wall of some connecting blocks 17, and other clamping plates 18 are rotatably connected to the side wall of other connecting blocks 17. With the cooperation of the connecting blocks 17 and the connector 16, the clamping plates 18 can be merged or expanded outward through the pull rod 14. When merged, the paper feed roller can be sleeved on it. When expanded outward, pressure can be applied to fix the paper feed roller, achieving the effect of outward expansion and clamping to prevent it from falling off during cleaning and causing secondary pollution.

[0035] Working principle: When cleaning and dust removal of the paper feed roller is required, pulling the hand-operated disc 19 moves the connecting piece 16 connected to the pull rod 14 downward. Since multiple connecting blocks 17 connect the clamping plate 18 and the connecting piece 16, when the connecting piece 16 moves downward, the clamping plate 18 is pulled inward through the connecting blocks 17. At this time, the paper feed roller is placed on the clamping plate 18, and the hand-operated disc 19 is released. Pulling the hand-operated disc 19 compresses the spring 15. After releasing the hand-operated disc 19, the spring 15 springs back to the connecting piece 16, causing the clamping plate 18 to expand outward, achieving the effect of outward clamping of the paper feed roller and preventing it from being damaged during cleaning. During dust removal, falling dust can cause secondary pollution. After fixing the paper feed roller, start motor 6 to drive the cross-shaped rotating part 9 connected to the rotating shaft 7 to rotate. Since the fixed gear plate 5 is fixed and the gear 12 meshes with it, the rotation of the cross-shaped rotating part 9 drives the gear 12 connected to the rotating shaft 11 to rotate around the fixed gear plate 5. At the same time, since the paper feed roller is clamped to the clamping plate 18 and the clamping plate 18 rotates with the gear 12, the paper feed roller is fixed and driven to rotate at the same time, so that the paper feed roller can be cleaned and dusted in all directions, avoiding cleaning dead corners and affecting the service life of the paper feed roller.
