Description

Technical Field

[0001] This utility model relates to the field of wire mesh production technology, and in particular to a wire mesh cleaning device. Background Technology

[0002] Wire mesh is a collective term for wire and mesh. Wire mainly refers to wire made of metal or non-metal materials; mesh is made of wire and woven into different shapes, densities and specifications according to requirements.

[0003] After the existing wire mesh is woven, it often needs to be cleaned with a mesh cleaning device to remove dust and dirt that has adhered to its surface due to weaving or other processes. Most existing mesh cleaning devices use rubber rollers to clean and absorb the dust and dirt on the mesh surface, so that the formed mesh can maintain a high forming quality. However, in actual operation, we have found that when using rubber rollers to clean the mesh surface, the adhesive on the rollers is very easy to adhere to the mesh surface during contact, affecting the forming quality of the wire mesh, and the actual use effect of the device is poor.

[0004] To address this issue, we have designed a mesh cleaning device to provide an alternative technical solution. Utility Model Content

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] Example

[0032] Reference Figure 1-9A wire mesh cleaning device includes a cleaning device body 1, a strip-shaped support plate 2, and a U-shaped mounting frame 3. Multiple strip-shaped support plates 2 are fixedly mounted on one side of the cleaning device body 1. The U-shaped mounting frame 3 is fixedly mounted on the strip-shaped support plate 2. The U-shaped mounting frame 3 contains multiple liquid silicone rollers 4 for cleaning the wire mesh surface, and multiple cleaning rollers 5 for cleaning the liquid silicone rollers 4. Pneumatic components for adjusting the position of each liquid silicone roller 4 are located on both sides of each cleaning roller 5, and fixing components for securing them are located on both sides of each cleaning roller 5. Specifically, the liquid silicone rollers 4 are used to absorb and clean dust and dirt adhering to the wire mesh surface, thereby avoiding unnecessary adhesion of adhesive to the wire mesh surface caused by using rubber rollers for cleaning, and improving the forming quality of the wire mesh 7.

[0033] It should be noted that in this utility model, multiple adhesive papers are adhered to the surface of the cleaning roller 5. The connection method between the adhesive paper and the cleaning roller 5 adopts existing technology, specifically referring to lint rollers. The adhesive force of the adhesive paper is greater than the adhesive force of the surface of the liquid silicone roller 4. Through this design, the adhesive paper absorbs the dust and dirt attached to the surface of the liquid silicone roller 4, thereby keeping the surface of the liquid silicone roller 4 clean and effectively ensuring the continuous operation of the cleaning device.

[0034] Reference Figure 2-3 The liquid silicone roller 4 is S-shaped and arranged inside the U-shaped mounting frame 3. Multiple cleaning rollers 5 are respectively arranged on one side of the liquid silicone roller 4 and abut against the outer edge of the liquid silicone roller 4. One side of one of the liquid silicone rollers 4 is provided with a receiving roller 6. The two ends of the receiving roller 6 are rotatably connected to the U-shaped mounting frame 3. The receiving roller 6 and the multiple liquid silicone rollers 4 are wound around the wire mesh 7 in an S-shape. Specifically, through the design of the receiving roller 6 and the S-shaped liquid silicone roller 4, the wire mesh 7 is wound around the receiving roller 6 and the liquid silicone roller 4 to clean the dust and dirt attached to both sides of the wire mesh 7, so that the surface of the wire mesh 7 can maintain a high degree of cleanliness and improve the forming quality of the wire mesh 7.

[0035] Reference Figure 4-5The pneumatic assembly includes guide blocks 8 on both sides of the liquid silicone roller 4. The U-shaped mounting frame 3 has guide grooves 9 and 10 that match the guide blocks 8. Airbags 11 and compression springs 12 abut against the upper and lower sides of the guide block 8 in guide groove 9, respectively. The opposite sides of airbags 11 and compression springs 12 are fixedly connected to the inner wall of guide groove 9. Airbag 13 abuts against the bottom of the guide block 8 in guide groove 10, and the bottom of airbag 13 is fixedly connected to the inner wall of guide groove 10. The U-shaped mounting frame 3 has internal structures corresponding to airbags 11 and 13. The air inlet is connected to the air inlet pipe 14 and the air inlet pipe 2 15. Specifically, through the design of the pneumatic components, the radial position of the liquid silicone roller 4 is controlled. This allows the operator to inflate the air inlet pipe 14 and the air inlet pipe 2 15, causing the airbags 11 and 2 13 to expand. This, in turn, compresses the guide block 8 in the guide grooves 19 and 20, causing it to move within the guide grooves 19 and 20 and come into contact with the liquid silicone roller 4. This cleans the dust and dirt adhering to the liquid silicone roller 4. The compression spring 12 supports the liquid silicone roller 4, thus cooperating with the airbag 11 to adjust the radial position of the liquid silicone roller 4.

[0036] Reference Figure 4 and Figure 6-8 The fixing assembly includes a mounting disc 16 and a square mounting block 17 disposed on both sides of the cleaning roller 5. The mounting disc 16 is rotatably disposed on one side of the square mounting block 17. An adjusting screw 18 is rotatably connected inside the mounting disc 16. A stationary ring 19 and a stationary ring 20 are rotatably connected to the adjusting screw 18. A moving ring 21 is provided on the opposite side of the stationary ring 19 and the stationary ring 20. The moving ring 21 is threadedly connected to the adjusting screw 18. The stationary ring 19 and the stationary ring 20... On one side opposite to the moving ring 21, multiple guide slide rods 22 are fixedly connected. The stationary ring 19, stationary ring 20 and guide slide rods 22 are fixedly mounted on the mounting disc 16. Multiple U-shaped blocks 23 are evenly distributed on the stationary ring 20 and the moving ring 21. Support rod 1 24 and support rod 25 are rotatably connected to the multiple U-shaped blocks 23 respectively. The connection between support rod 1 24 and support rod 25 is rotatably connected together and a rubber pad 26 that abuts against the inner wall of the cleaning roller 5 is fixedly mounted on it.

[0037] The end of the adjusting screw 18 away from the stationary ring 19 is rotatably connected to the inner wall of the square mounting block 17. A driven bevel gear 27 is fixedly connected to a section of the adjusting screw 18 located inside the square mounting block 17. A driving bevel gear 28 meshes with the driven bevel gear 27. A rotating shaft 29 is fixedly connected to the top center of the driving bevel gear 28. The end of the rotating shaft 29 away from the driving bevel gear 28 passes through the square mounting block 17 and is connected to an adjusting knob 30. Specifically, through the design of the fixing components, when installing the cleaning roller 5, the operator only needs to connect both ends of the cleaning roller 5. The adjustment screw 18 is fitted onto the outside of the adjustment screw 18. Then, the adjustment knob 30 on the square mounting block 17 is rotated in sequence to make the drive bevel gear 28 on the rotating shaft 29 drive the driven bevel gear 27 to rotate. This causes the adjustment screw 18 in the middle of the driven bevel gear 27 to rotate, so that the moving ring 21 threaded on it moves toward the stationary ring 20. This causes the support rod 1 24 and support rod 25 rotatably connected to the moving ring 21 and the stationary ring 20 to expand outward. The cleaning roller 5 is supported by the rubber pad 26 fixed at the connection between the support rod 1 24 and the support rod 25. This completes the fixed installation of the cleaning roller 5 in the U-shaped mounting bracket 3.

[0038] Reference Figure 9 The square mounting block 17 has multiple guide rails 31 fixedly connected to both sides. The U-shaped mounting bracket 3 has multiple guide rails 32 that match the guide rails 31. Each of the square mounting blocks 17 has a square sleeve block 33 and a square plate 34 on one side. The square mounting block 17 located on the side of the square sleeve block 33 has multiple guide blocks 35 fixedly connected. The square sleeve block 33 has a guide groove 36 that matches the guide block 35 inside. The square mounting block 17 has multiple compression springs 37 on the side near the square sleeve block 33. The two ends of the compression springs 37 are fixedly connected to the side walls of the square mounting block 17 and the square sleeve block 33, respectively. The square sleeve block 33 has a strip groove 38 that matches the rotating shaft 29 and the guide rail 31.

[0039] The square plate 34 is fixedly connected to one side of the square mounting block 17, and a handle 39 for easy pulling is fixedly connected to the side opposite to the square mounting block 17. The U-shaped mounting frame 3 is provided with an opening 40 that matches the square mounting block 17. An annular magnetic strip 41 is fixedly provided on the side of the square plate 34 near the square mounting block 17. An annular groove 42 that matches the annular magnetic strip 41 is provided on the opening 40. Specifically, through the design and fixing components of the square sleeve block 33, guide block 35, guide groove 36 and compression spring 37, it is convenient for the operator to install and remove the cleaning roller 5 in the U-shaped mounting frame 3. When installing the cleaning roller 5, the operator can first place one end of the cleaning roller 5 against the square plate 34. One side of the mounting block 17 is pressed, causing the square mounting block 17 to move inside the square sleeve block 33 and compressing the compression spring 37, so that the other end of the cleaning roller 5 can be sleeved on the outside of the adjusting screw 18. Then the force applied to the cleaning roller 5 is stopped, and the square mounting block 17 is reset under the action of the compression spring 37. The guide block 35 restricts the extreme position of the movement of the square mounting block 17. Then the operator adjusts the position of the cleaning roller 5 outside the adjusting screw 18 so that the cleaning roller 5 is in the middle of the U-shaped mounting frame 3 and its two ends are flush with the two ends of the liquid silicone roller 4. Then the adjusting knob 30 is turned to fix the cleaning roller 5, thus completing the installation of the cleaning roller 5 in the U-shaped mounting frame 3.

[0040] The design of the guide slide bar 31, guide slide rail 32 and handle 39 makes it easy for the operator to pull the cleaning roller 5 out of the U-shaped mounting bracket 3 to replace the cleaning roller 5 or the multiple adhesive papers adhering to the cleaning roller 5, thereby improving the actual use effect of the device. The design of the annular magnetic strip 41 and annular groove 42 applies a certain axial limiting force to the fixed cleaning roller 5, preventing the cleaning roller 5 from unnecessary displacement on the guide slide rail 32 due to small vibrations of the machine, further improving the actual use effect of the device.

[0041] It should be noted that in this utility model, the guide groove in the guide rail 32 is not a through groove at the end near the opening 40, and the guide strip 31 is L-shaped at the end away from the opening 40. Through the cooperation of the guide strip 31 and the guide rail 32, the extreme position of the cleaning roller 5 is limited, thereby avoiding damage caused by the worker accidentally pulling the cleaning roller 5 out of the guide rail 32, and improving the actual use effect of the device. Through the design of multiple strip grooves 38 on the square sleeve block 33, the square mounting block 17 is easy to move in the square sleeve block 33, avoiding jamming during the movement of the square mounting block 17, and effectively ensuring the stable operation of the device.

[0042] The usage process of the mesh cleaning device provided by this utility model is as follows:

[0043] When cleaning the dust and dirt adhering to the surface of the wire mesh 7, the operator only needs to inflate the air inlet pipe 14 and the air inlet pipe 25 to inflate the airbag 11 and the airbag 23, and squeeze the guide block 8 in the guide groove 19 and the guide groove 20, so that it moves in the guide groove 19 and the guide groove 20 and comes into contact with the liquid silicone roller 4. Then the operator winds the wire mesh 7 sequentially around the receiving roller 6 and the liquid silicone roller 4, and starts the externally connected winding device. The adsorption property of the liquid silicone roller 4 can be used to clean the dust and dirt adhering to both sides of the wire mesh 7, thereby effectively improving the forming quality of the wire mesh 7.

[0044] When installing the cleaning roller 5, the operator first pulls the handle 39 to remove the square plate 34, square sleeve 33, and fixing assembly from the opening 40. Then, one end of the cleaning roller 5 is placed against one side of the square mounting block 17, and the square mounting block 17 is pressed. During this process, the operator needs to provide a certain pulling force to the handle 39 to prevent the square sleeve 33 from moving towards the U-shaped mounting bracket 3 under the pressure of the square mounting block 17, thus ensuring the normal movement of the square mounting block 17 within the square sleeve 33, and pressing the compression spring 37 to facilitate operation. The operator places the other end of the cleaning roller 5 on the outside of the adjusting screw 18, and then stops applying force to the cleaning roller 5. The square mounting block 17 is reset under the action of the compression spring 37, and the guide block 35 restricts the extreme position of the square mounting block 17. Then the operator adjusts the position of the cleaning roller 5 outside the adjusting screw 18 so that the cleaning roller 5 is in the middle of the U-shaped mounting frame 3 and its two ends are flush with the two ends of the liquid silicone roller 4. Then the operator rotates the adjusting knob 30 to fix the cleaning roller 5, thus completing the installation of the cleaning roller 5 in the U-shaped mounting frame 3.

[0045] When replacing the cleaning roller 5 or the adhesive paper, the operator only needs to pull the handle 39 to pull the cleaning roller 5 out of the U-mount frame, and then peel off the adhesive paper that needs to be replaced from the cleaning roller 5.
