Description

Technical Field

[0001] This invention relates to the field of cleaning technology, and more particularly to a cleaning device for the production of sewage pumps. Background Technology

[0002] In the production of sewage pumps, a large number of pipe fittings (such as pump body connecting pipes, inlet and outlet pipes, etc.) require thorough cleaning of their inner and outer walls after processing to remove oil, chips, and rust. Common cleaning equipment used in sewage pump production often employs immersion cleaning or a fixed rotating brush roller structure. However, such equipment has drawbacks. Existing equipment typically requires separate inner and outer wall cleaning stations, or different brush heads and tooling, to clean the inner and outer walls. It cannot flexibly switch between inner and outer wall cleaning or simultaneous inner and outer wall cleaning by adjusting the brush roller position. This results in complex equipment structures, limited adaptability to specific specifications, and frequent tooling changes that severely impact cleaning efficiency.

[0003] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a cleaning device for sewage pump production, so as to solve the problem that the above-mentioned method of cleaning the inner wall, outer wall or the inner and outer walls simultaneously cannot be flexibly switched by adjusting the position of the brush roller.

A support shell and a support frame are provided above the rotating seat. A pressing roller for pressing the pipe to be cleaned is rotatably connected to the support frame. A sliding plate is slidably provided inside the support shell. The support frame and the sliding plate are fixedly connected.

With the operator picking up and placing workpieces, continuous operation is achieved, significantly improving cleaning efficiency. After the cleaning rollers press against the pipe wall, the self-rotation component drives the corresponding cleaning station's pipe to rotate, allowing the cleaning rollers to complete a uniform cleaning of the entire circumference of the pipe to be cleaned, ensuring thorough cleaning and avoiding dead corners.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0020] Example 1, by Figure 1 and Figure 2The present invention includes a cleaning box 1 and a lifting seat 4 disposed above the cleaning box 1. A first electric push rod 5 is fixedly connected to the cleaning box 1, and the telescopic end of the first electric push rod 5 is fixedly connected to the lifting seat 4. The cleaning box 1 is provided with a plurality of brackets 2 for supporting the bottom of the pipe fitting 50 to be cleaned. The plurality of brackets 2 are distributed in a circle inside the cleaning box 1. The brackets 2 and the side wall of the cleaning box 1 are fixedly connected by a connecting rod 3. The cleaning box 1 contains two cleaning rollers 10 for cleaning the pipe fitting 50 to be cleaned. A position adjustment structure is installed on the lifting seat 4 to adjust the position of the two cleaning rollers 10. The cleaning box 1 also contains a rotation component for driving the pipe fitting 50 to be cleaned at the cleaning station to rotate. The position adjustment structure has a first revolution mode and a second revolution mode. In the first revolution mode, the position adjustment structure drives the two cleaning rollers 10 to revolve around the circumferential distribution center of several brackets 2 as the first center, thereby adjusting the switching of the cleaning rollers 10 between different cleaning stations and moving the cleaning rollers 10 toward the inner or outer wall of the pipe fitting 50 to be cleaned. In the second revolution mode, the position adjustment structure drives the two cleaning rollers 10 to rotate relative to each other. The two cleaning rollers 10 revolve around the midpoint of the second center, so that they press against the surface of the pipe fitting 50 to be cleaned. The operator adds cleaning fluid into the cleaning tank 1, and then places several pipe fittings 50 to be cleaned onto several brackets 2 in sequence. When it is necessary to clean the inner and outer walls of the pipe fitting 50 located at one of the cleaning stations at the same time, the two cleaning rollers 10 are driven to revolve around the center of the several brackets 2 in a circular distribution by the position adjustment structure. When the two cleaning rollers 10 move to the preset position, the lifting seat 4 is driven to move down by the first electric push rod 5, so that one cleaning roller 10 is inserted into the inside of the pipe fitting 50 to be cleaned, and the other cleaning roller 10 is located on the outside of the pipe fitting 50 to be cleaned. Then, the position adjustment structure drives the two cleaning rollers 10 to revolve around the midpoint between the two cleaning rollers 10. Finally, the two cleaning rollers 10 contact the inner and outer walls of the pipe fitting 50 to be cleaned, respectively. When only the outer or inner wall of the pipe fitting 50 needs to be cleaned, the position adjustment structure drives the two cleaning rollers 10 to revolve around the center of a plurality of brackets 2 arranged in a circle. When the two cleaning rollers 10 move to the preset position, the first electric push rod 5 drives the lifting seat 4 to move down, so that the two cleaning rollers 10 are both inside or outside the pipe fitting 50 to be cleaned. Then, the position adjustment structure drives the two cleaning rollers 10 to revolve around the center of a plurality of brackets 2 arranged in a circle, so that the cleaning rollers 10 are both inside or outside the pipe fitting 50 to be cleaned. The cleaning roller 10 moves toward the inner or outer wall of the pipe to be cleaned 50, and drives the two cleaning rollers 10 to revolve around the midpoint between the two cleaning rollers 10 through the position adjustment structure, so that both cleaning rollers 10 are in contact with the inner or outer wall of the pipe to be cleaned 50. Finally, the self-rotation component drives the pipe to be cleaned 50 located at the corresponding cleaning station to rotate, and the cleaning roller 10 can clean the pipe to be cleaned 50 in one circle. When the cleaning is completed, the first electric push rod 5 drives the lifting seat 4 to move up, so that the cleaning roller 10 is pulled out from the cleaning box 1. The position adjustment structure can drive the cleaning roller 10 to move to the next cleaning station, and the operator can take out the cleaned workpiece located at the previous cleaning station.

[0021] Example 2, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The position adjustment structure includes a first servo motor 8 fixedly mounted on a lifting base 4. The output end of the first servo motor 8 is fixedly connected to a first rotating shaft 7. Several brackets 2 are circumferentially distributed with their centers located on the axis of the first rotating shaft 7. A rotating frame 9, located above the cleaning box 1, is rotatably mounted on the outside of the first rotating shaft 7. A first synchronous wheel 11 is fixedly connected to the bottom of the rotating frame 9. A second synchronous wheel 12 is fixedly mounted on the outside of the first rotating shaft 7, and the second synchronous wheel 12 is in contact with the first synchronous wheel 11. A straightening component adapted to the rotating frame 9 is mounted on the lifting base 4. A second rotating shaft 14 is rotatably connected to the rotating frame 9. A rotating shell 13 is fixedly connected to the bottom of the second rotating shaft 14, and both cleaning rollers 10 are rotatably connected to the rotating shell 13. A rotation unit for driving the second rotating shaft 14 to rotate is mounted on the rotating frame 9. The rotation unit includes a second servo motor 16 fixedly mounted on the rotating frame 9. A third synchronous wheel 15 is fixedly connected to the top of the second rotating shaft 14. The output end of the servo motor 16 is fixedly connected to the fourth synchronous wheel 17, and the bottom of the fourth synchronous wheel 17 is in contact with the top of the third synchronous wheel 15. The third synchronous wheel 15 is fixedly connected to the fixed column 18. The rotating frame 9 is fixedly connected to the correction plate 19 which limits the position of the fixed column 18. The rotating shell 13 is rotatably connected to the rotating shaft 20. The rotating shell 13 is fixedly connected to the third servo motor 21. The output end of the third servo motor 21 is fixedly connected to the rotating shaft 20. The rotating shaft 20 is fixedly sleeved with two worm gears 22. The top end of the cleaning roller 10 is fixedly connected to the worm wheel 23 located in the rotating shell 13. The two worm gears 23 are respectively meshed with the two worm gears 22. The straightening component includes a lifting ring 28 set above the rotating frame 9. The lifting seat 4 is fixedly connected to the second electric push rod 30. The telescopic end of the second electric push rod 30 is fixedly connected to the lifting ring 28. The bottom of the lifting ring 28 is fixedly connected to several straightening columns 29. The number of straightening columns 29 is the same as that of the bracket 2. When the first servo motor 8 drives the first rotating shaft 7 and the second synchronous wheel 12 to rotate, the second synchronous wheel 12 synchronously drives the first synchronous wheel 11 and the rotating frame 9 to rotate through friction, so that the cleaning roller 10 revolves around the center of a plurality of brackets 2 arranged in a circle. When the lifting seat 4 is driven to move down by the first electric push rod 5, so that one of the cleaning rollers 10 is inserted into the inside of the pipe 50 to be cleaned and the other cleaning roller 10 is located outside the pipe 50 to be cleaned, the second servo motor 16 drives the fourth synchronous wheel 17 to rotate. The fourth synchronous wheel 17 drives the third synchronous wheel 15 to rotate through friction. The third synchronous wheel 15 drives the rotating shell 13 and the cleaning roller 10 to revolve around the midpoint between the two cleaning rollers 10 through the second rotating shaft 14. One cleaning roller 10 inside the pipe fitting 50 first contacts the inner wall of the pipe fitting 50. As the second rotating shaft 14 and the rotating shell 13 continue to rotate, the cleaning roller 10 located inside the pipe fitting 50 uses the cleaning roller 10 inside the pipe fitting 50 as a support point, and the cleaning roller 10 located outside the pipe fitting 50 continues to move towards the outer wall of the pipe fitting 50. The rotating frame 9 drives the first synchronous wheel 11 to rotate relative to the second synchronous wheel 12 against friction. When the two cleaning rollers 10 contact the inner and outer walls of the pipe fitting 50 respectively, as the fourth synchronous wheel 17 continues to rotate, the fourth synchronous wheel 17 cannot drive the third synchronous wheel 15 to rotate synchronously through friction. When the two cleaning rollers 10 contact the inner and outer walls of the pipe fitting 50 respectively, the cleaning roller 10... The movement will automatically stop. When the first electric push rod 5 drives the lifting seat 4 to move downwards so that both cleaning rollers 10 are inside or outside the pipe 50 to be cleaned, the first servo motor 8 drives the first rotating shaft 7 to rotate, so that both cleaning rollers 10 move towards the inner or outer wall of the pipe 50 to be cleaned. The second servo motor 16 drives the fourth synchronous wheel 17 to rotate, and the second rotating shaft 14 drives the two cleaning rollers 10 to rotate, allowing the cleaning rollers 10 to contact the inner or outer wall of the pipe 50 to be cleaned. After cleaning, the second servo motor 16 drives the fourth synchronous wheel 17 to rotate in the opposite direction. When the fourth synchronous wheel 17 drives the third synchronous wheel 15 and the fixed column 18 to rotate synchronously through friction, the fixed column 18 and the correction plate 19... Upon contact, the third synchronous wheel 15 and the rotating shell 13 rotate in the opposite direction to the initial position relative to the rotating frame 9, thus completing the correction of the initial position of the cleaning roller 10 relative to the rotating frame 9. Simultaneously, the second electric push rod 30 drives the lifting ring 28 downwards, so that the bottom horizontal position of the correction column 29 is lower than the top horizontal position of the rotating frame 9. The first servo motor 8 drives the first rotating shaft 7 to rotate in the opposite direction. The first rotating shaft 7 drives the second synchronous wheel 12 to drive the first synchronous wheel 11 and the rotating frame 9 to rotate in the opposite direction through friction until the rotating frame 9 abuts against a corresponding correction column 29. The rotating frame 9 and the first synchronous wheel 11 then stop rotating with the first rotating shaft 7. The rotating frame 9 automatically stops after rotating to the preset position, while the first servo motor 8 continues to drive the first rotating shaft 7 to rotate.After the first rotating shaft 7 rotates relative to the lifting seat 4 to its initial position and stops, the rotating frame 9 and the first synchronous wheel 11 are then aligned to their initial positions relative to the first rotating shaft 7 and the second synchronous wheel 12. The third servo motor 21 drives the rotating shaft 20 and the worm gear 22 to rotate. The worm gear 22 drives the cleaning roller 10 to rotate via the worm wheel 23. Different positions on the cleaning roller 10 can be used to clean the pipe fitting 50.

[0022] Example 3, based on Example 2, by Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 The rotating assembly includes two support rollers 6 rotatably mounted on a bracket 2. A driver for driving the two support rollers 6 located at the cleaning station is mounted on a first rotating shaft 7. A pressing mechanism for pressing the pipe fitting 50 to be cleaned located at the cleaning station is also mounted on the first rotating shaft 7. The driver includes a mounting bracket 24 fixedly mounted on the first rotating shaft 7. Two fourth servo motors 25 are fixedly connected to the mounting bracket 24. A fifth synchronous pulley 26 is fixedly connected to the output end of the fourth servo motor 25. The top of the support rollers 6 is fixedly connected to the fifth synchronous pulley 26. The sixth synchronous wheel 27 below 6 has a pressing mechanism including a rotating sleeve 31 sleeved on the outside of the first rotating shaft 7. The bottom end of the rotating sleeve 31 is rotatably connected to the bottom of the inner wall of the cleaning box 1. Several guide grooves 32 are provided on the inner wall of the rotating sleeve 31. Guide strips 33 are slidably arranged in the guide grooves 32, and the guide strips 33 are fixedly connected to the first rotating shaft 7. A rotating seat 34 is fixedly sleeved on the outside of the rotating sleeve 31. A support shell 35 and a support frame 37 are provided above the rotating seat 34. A pressing roller 36 for pressing the pipe fitting 50 to be cleaned is rotatably connected to the support frame 37. A sliding plate 38 is slidably mounted inside the support shell 35. The support frame 37 and the sliding plate 38 are fixedly connected. The side of the sliding plate 38 away from the support frame 37 is connected to the inner wall of the support shell 35 by several compression springs 39. A control component for adjusting the horizontal position of the support shell 35 is mounted on the rotating seat 34. The control component includes an adjusting plate 40 fixedly mounted on the bottom of the support shell 35. Two lead screws 41 pass through the adjusting plate 40. The lead screws 41 are fixedly connected to the rotating seat 34. Two nuts 42 are threaded on the external threads of the lead screws 41, and two adjacent nuts 42 are respectively engaged with the adjusting plate 40. The two sides of the plate 40 are in contact with each other. A first annular groove 43 is provided on the rotating seat 34. A support ring 44 is rotatably connected in the first annular groove 43. The bottom of the bracket 2 and the bottom of the connecting rod 3 are fixedly connected to the top of the support ring 44. A fixing ring 45 is fixedly connected to the inner wall of the cleaning box 1. A second annular groove 46 is provided on the fixing ring 45. A slider 47 is slidably provided in the second annular groove 46. The end of the screw 41 away from the rotating seat 34 is fixedly connected to the slider 47. A faucet 48 for draining the cleaning liquid in the cleaning box 1 is installed at the bottom of the cleaning box 1. The operator places the pipe fitting 50 to be cleaned above the bracket 2, with the outer wall of the pipe fitting 50 in contact with the two adjacent support rollers 6. When the first electric push rod 5 drives the lifting seat 4 to move down, the lifting seat 4 drives the first rotating shaft 7 and the guide bar 33 to slide relative to the guide groove 32 and the rotating sleeve 31. When the first servo motor 8 drives the first rotating shaft 7 to rotate, the first rotating shaft 7 drives the rotating sleeve 31 to rotate via the guide bar 33. The rotating sleeve 31 drives the rotating seat 34, the support shell 35, and the pressing roller 36 to rotate synchronously. The rotating seat 34 and the first annular groove 43 rotate relative to the support ring 44, and the rotating seat 34 and the support ring 44 support the bottom of the bracket 2 and the connecting rod 3. To reduce the possibility of tilting and swaying of the bracket 2, the pressing roller 36 eventually rotates to one side of the pipe fitting 50 to be cleaned. The pressing roller 36 presses down on the pipe fitting 50 located at the corresponding cleaning station. As the rotating seat 34 and the support shell 35 continue to rotate, the support frame 37 and the sliding plate 38 slide relative to the support shell 35. The compression spring 39 is in a compressed state and applies pressure to the sliding plate 38 so that the pressing roller 36 presses down on the pipe fitting 50 to be cleaned. The pipe fitting 50 to be cleaned is fixed between the pressing roller 36 and the two cleaning rollers 10. According to the specifications of the batch of pipe fittings 50 to be cleaned, the operator drives the nut 42 to rotate relative to the screw 41 so that the two adjacent pipe fittings 50 are pressed down. Nut 42 no longer clamps the adjusting plate 40. Then, the operator drives the adjusting plate 40 and the support shell 35 to translate relative to the lead screw 41 and the rotating seat 34, thereby changing the initial position of the support shell 35 and the pressing roller 36. Then, the operator drives the two adjacent nuts 42 to clamp the adjusting plate 40 again, so that the support shell 35 and the adjusting plate 40 are fixed relative to the lead screw 41 and the rotating seat 34. When the rotating seat 34 rotates, the rotating seat 34 drives the slider 47 to slide in the second annular groove 46 through the lead screw 41. Through the design of the fixing ring 45, the second annular groove 46 and the slider 47, the end of the lead screw 41 away from the rotating seat 34 is supported, reducing the possibility of the lead screw 41 tilting and wobbling. When the first rotating shaft 7 drives the cleaning roller 10 to rotate to the preset position, the first rotating shaft 7 drives the mounting bracket 24 and the fifth synchronous wheel 26 to rotate synchronously above the corresponding sixth synchronous wheel 27. The first electric push rod 5 drives the lifting seat 4 to move down, and the fifth synchronous wheel 26 can then contact the sixth synchronous wheel 27. The fourth servo motor 25 drives the fifth synchronous wheel 26 to rotate, and the fifth synchronous wheel 26 can then drive the sixth synchronous wheel 27 to rotate through friction. The sixth synchronous wheel 27 can then drive the support roller 6 to rotate, and the support roller 6 can then drive the pipe to be cleaned 50 to rotate relative to the bracket 2 through friction. By opening the faucet 48 on the cleaning box 1, the cleaning liquid in the cleaning box 1 can be discharged.

[0023] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
