Description

Technical Field

[0001] This invention relates to the field of air compressors, specifically to an oil-free lubricated compressor mechanism. Background Technology

[0002] A compressor is a mechanical device that raises low-pressure gas to high-pressure gas and delivers it out. An oil-free compressor is a compressor that does not use lubricating oil in the compressor cylinder. Its internal piston is usually made of self-lubricating material, and the inner wall of the cylinder is generally specially treated.

[0003] For example, Chinese Patent Publication No. CN119656743A discloses an air compressor filter that facilitates filter replacement, comprising: a filter body and two partitions symmetrically fixedly installed inside the filter body, a turntable between the two partitions, two symmetrically distributed mounting frames slidably installed on the outer side of the turntable, multiple layers of filter screens being provided on the inner side of the mounting frames, and two symmetrically distributed guide tubes being fixedly installed on the inner side of the filter body.

[0004] In this solution, the combination of multiple layers of filters, a rotating disc, and a breathable filter plate causes a large amount of dust to accumulate on the upper filters and filter plates. This allows the filter plates to rotate 180° to replace the unused filters and filter plates on the lower side with those on the upper side. This results in a reduction in airflow. Furthermore, during the rotation, the filter plates contract towards the filter due to their elasticity. This can cause dust to fall off when the filter plates come into contact with the filter due to their elasticity. Additionally, the use of bolts for installation and fixation makes it difficult to quickly disassemble and clean the filters and filter plates. Summary of the Invention

[0012] As a further aspect of the present invention: a first winding cylinder, a second winding cylinder, and a drive rod are rotatably connected to the side wall of the inner cavity of the cleaning plate near the rotating shaft. The drive rod is rotatably connected to the middle part of the inner cavity of the cleaning plate near the filter screen. A rotating cylinder is rotatably connected to the outer wall of the drive rod. The outer wall of the rotating cylinder is in contact with the filter screen. The rotating cylinder, the first winding cylinder, and the second winding cylinder have the same vertical height. Adhesive tape is wrapped around the middle part of the outer wall of the second winding cylinder. The end of the adhesive tape away from the second winding cylinder passes around the outer wall of the rotating cylinder and is wrapped around the middle part of the first winding cylinder.

[0013] As a further aspect of the present invention: a cover plate is threadedly connected to the end of the cleaning plate away from the rotating shaft; a driven rod is fixedly connected to the middle of the end of the first winding cylinder near the cover plate; the end of the driving rod away from the rotating shaft passes through the cover plate; a gear is fixedly connected to the end of the driving rod away from the cover plate; an annular groove is provided on the side of the positioning frame near the gear; a toothed ring is fixedly connected to the inner cavity of the annular groove; the toothed ring meshes with the gear; and a synchronous belt is connected to the upper outer wall of the driving rod and the driven rod for transmission.

[0014] As a further aspect of the present invention: a symmetrical groove is provided at the bottom of the inner cavity of the fixed plate near the driven plate; a symmetrical plug rod is fixedly connected to the middle of the lower end of the annular plate; a limiting block is elastically connected to the middle of the inner cavity of the plug rod near the center of the annular plate; an inclined surface is provided at the lower part of the limiting block away from the plug rod; and a limiting groove is provided at the lower part of the inner cavity of the groove near the center of the annular plate.

[0015] As a further aspect of the present invention: a driven groove is provided on the side of the inner cavity of the fixed plate away from the mounting plate.

The driven plate is slidably connected to the inner cavity of the driven groove. A through groove is provided on the side of the annular plate near the fixed plate to slide with the driven plate.

[0016] As a further aspect of the present invention: an arc-shaped inclined edge is provided on the side of the driven plate near the center of the annular plate, an arc-shaped groove is provided on the lower part of the driven plate near the adjusting rod, the side of the contact rod away from the cleaning plate is slidably engaged with the arc-shaped groove, a baffle is fixedly connected to the upper end of the arc-shaped inclined edge, and a one-way rotating plate is fitted to the inner cavity of the arc-shaped groove on the side away from the arc-shaped inclined edge.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The clockwise rotation of the adjusting rod and the contact rod cleans the dust on the filter screen while the compressor is running, ensuring that the dust does not fall off the filter screen. During the dust cleaning process, the tape continuously wraps around the outer wall of the first winding cylinder, ensuring that the tape has the same efficient cleaning capability for all parts of the filter screen's outer wall during clockwise rotation. The counterclockwise rotation of the adjusting rod and the contact rod, driven by the servo motor, drives the driven plate to push the limiting block into the inner cavity of the plug-in rod, releasing the limiting effect of the fixing plate on the mounting plate and the annular plate, facilitating the disassembly and installation of the mounting plate and the annular plate. The baffle plate restricts the rotation of the contact rod after it contacts the baffle plate, thus ensuring that the limiting block will not spring back and get stuck in the limiting groove during the disassembly of the mounting plate and the annular plate.

[0031] Please see Figure 1-3 In this embodiment of the invention, an oil-free lubrication compressor mechanism includes a compressor 1 and an intake pipe 2. An oil-free lubrication compressor refers to a compressor that does not use lubricating oil in the compressor cylinder. It mainly includes piston type and screw type. The piston inside is usually made of self-lubricating material, and the inner wall of the cylinder is generally specially treated, such as by using an anodized coating, which is a commonly used technical means in the prior art. A connecting pipe 3 is fixedly connected to the side of the intake pipe 2 away from the compressor 1. The connecting pipe 3 is installed vertically during use. A mounting plate 4 is slidably connected to the middle of the upper end of the connecting pipe 3. An annular plate 9 is fixedly connected to the middle of the inner cavity of the mounting plate 4. A filter screen 7 is provided in the inner cavity of the annular plate 9. A cleaning mechanism for cleaning dust on the filter screen 7 is provided at the top of the inner cavity of the annular plate 9. A driven plate 31 is slidably connected to the middle of the side of the annular plate 9 away from the mounting plate 4. When the cleaning mechanism rotates clockwise, the driven plate 31 remains stationary. When the cleaning mechanism rotates counterclockwise, the driven plate 31 moves to a position away from the center of the annular plate 9.

[0032] A fixing plate 5 is attached to the lower end of the mounting plate 4. Connecting pipes 3 are fixedly connected to both sides of the fixing plate 5. One connecting pipe 3 is connected to the air inlet pipe 2, and the other connecting pipe 3 is connected to the air inlet pipe. Gas passes through the connecting pipe 3 and the filter screen 7 and enters the compressor 1 from the air inlet pipe 2. After being pressurized in the inner cavity of the compressor 1, it is output from the outlet. A positioning frame 6 is fixedly connected to one side of the lower end of the annular plate 9. A mounting frame 11 is attached to the side of the positioning frame 6 near the air inlet pipe 2. The filter screen 7 is fixedly connected to the middle of the mounting frame 11. An iron sheet 12 is fixedly connected to the side of the mounting frame 11 near the positioning frame 6. Symmetrical magnets 13 are fixedly connected to the side of the positioning frame 6 near the mounting frame 11. The iron sheet 12 is magnetically attracted and fixed by the magnets 13, thus completing the installation and fixing of the mounting frame 11 and the filter screen 7. At the same time, the magnetic fixing method also makes it easy to disassemble and replace the mounting frame 11 and the filter screen 7.

[0033] Please see Figure 3-6 The cleaning mechanism includes a vertical plate 21, which is fixedly connected to the upper part of the inner cavity of the annular plate 9, away from the positioning frame 6. A servo motor 22 is driven to the lower end of the vertical plate 21. A rotating shaft 26 is fixedly connected to the output end of the servo motor 22. A ring 27 is rotatably connected to the middle of the rotating shaft 26. A cleaning plate 14 is fixedly connected to the outer wall of the ring 27. The rotational engagement between the ring 27 and the rotating shaft 26 enables the rotational engagement between the cleaning plate 14 and the rotating shaft 26. An adjusting rod 23 is fixedly connected to the middle of the upper end of the rotating shaft 26. A contact rod 24 is fixedly connected to the end of the adjusting rod 23 away from the rotating shaft 26. A fixing rod 16 is fixedly connected to the side of the cleaning plate 14 closest to the vertical plate 21. When the servo motor 22 drives the rotating shaft 26 to rotate clockwise, the rotating shaft 26 will... The adjusting rod 23 and the contact rod 24 rotate clockwise synchronously, while the cleaning plate 14 remains stationary until the side of the contact rod 24 near the cleaning plate 14 contacts the side wall of the fixed rod 16. At this point, the rotating contact rod 24 contacts the outer wall of the fixed rod 16, pushing the fixed rod 16 to rotate synchronously, thereby causing the cleaning plate 14 to rotate synchronously. That is, when the adjusting rod 23 and the contact rod 24 rotate clockwise and contact the side of the fixed rod 16 near the middle of the cleaning plate 14, they will cause the fixed rod 16 and the cleaning plate 14 to rotate clockwise synchronously. If the rotating shaft 26 rotates counterclockwise at this time when the contact rod 24 contacts the fixed rod 16, the adjusting rod 23 and the contact rod 24 will separate from the side wall of the fixed rod 16, and the cleaning plate 14 will return to a stationary state.

[0034] Please see Figure 5 , Figure 7The inner cavity of the cleaning plate 14 is rotatably connected to a first winding cylinder 29, a second winding cylinder 30, and a drive rod 20 on the side wall near the rotating shaft 26. The first winding cylinder 29 and the second winding cylinder 30 are the same size but in different positions. The drive rod 20 is rotatably connected to the middle of the inner cavity of the cleaning plate 14 near the filter screen 7. The outer wall of the drive rod 20 is rotatably connected to a rotating cylinder 25, and the outer wall of the rotating cylinder 25 is in contact with the filter screen 7. The rotating cylinder 25, the first winding cylinder 29, and the second winding cylinder 30 are at the same vertical height. A piece of tape 28 is wrapped around the middle of the outer wall of the second winding cylinder 30. One end of the tape 28, away from the second winding cylinder 30, wraps around the outer wall of the rotating cylinder 25 and is wrapped around the middle of the first winding cylinder 29. When the first winding cylinder 29 rotates counterclockwise, it continuously wraps the tape 28 from the outer wall of the second winding cylinder 30 onto the outer wall of the first winding cylinder 29. Because the tape 28 adheres to the outer wall of the rotating cylinder 25, during the continuous wrapping of the tape 28 by the first winding cylinder 29, the tape 28 will pass through the rotating cylinder 25 and the outer wall of the rotating cylinder 25. The friction between the two parts drives the rotating drum 25 to rotate, making the process of the first winding drum 29 winding the tape 28 smoother. Since the side of the tape 28 away from the rotating drum 25 is sticky, as the cleaning plate 14 drives the rotating drum 25 to rotate clockwise, the tape 28 will stick off the dust adhering to the outer wall of the filter screen 7, thus completing the cleaning of the dust on the filter screen 7. Furthermore, the rotation of the first winding drum 29 continuously moves the tape 28, causing the dust adhering to the outer wall of the rotating drum 25 to... The tape 28 will be wound onto the outer wall of the first winding cylinder 29, while the tape 28 without dust adhering to the outer wall of the second winding cylinder 30 will continuously move to the outer wall of the rotating cylinder 25. As the cleaning plate 14 rotates clockwise, the tape 28 at the position of the rotating cylinder 25 can be replaced with new adhesive tape 28 in time after it has stuck to dust. This allows the cleaning plate 14 and the rotating cylinder 25 to have a continuous ability to clean the dust on the filter screen 7, and the dust cleaning effect will not deteriorate with the use time.

[0035] Please see Figure 4-6A cover plate 15 is threadedly connected to the end of the cleaning plate 14 away from the rotating shaft 26. The cover plate 15 can be removed from the cleaning plate 14. A driven rod 17 is fixedly connected to the middle of the end of the first winding cylinder 29 near the cover plate 15. The end of the drive rod 20 away from the rotating shaft 26 passes through the cover plate 15. A sliding groove is provided on the side wall of the cover plate 15 to slide with the drive rod 20 and the driven rod 17, so that the drive rod 20 and the driven rod 17 will not obstruct the disassembly process of the cover plate 15. A gear 19 is fixedly connected to the end of the drive rod 20 away from the cover plate 15. An annular groove 8 is provided on the side of the positioning frame 6 near the gear 19. A gear ring 10 is fixedly connected to the inner cavity of the annular groove 8. The gear ring 10 and the gear 19 mesh with each other. During the clockwise rotation of the cleaning plate 14 driven by the rotating shaft 26, the drive rod 20 is driven to rotate counterclockwise under the cooperation of the gear ring 10 and the gear 19. The upper outer wall of the drive rod 20 and the driven rod 17 are connected by a synchronous belt 18. The synchronous belt 18 drives the driven rod 17 to rotate with the rotation of the drive rod 20, thereby driving the first winding drum 29 to rotate. This achieves the simultaneous cleaning of dust on the filter screen 7 by the cleaning plate 14, the rotating drum 25 and the tape 28, while the tape 28 with dust adhering to it is wrapped around the outer wall of the first winding drum 29 in real time. This ensures the cleaning ability of the tape 28 and also prevents dust from falling off the filter screen 7 during cleaning, thus preventing the dust from being effectively cleaned.

[0036] Please see Figure 9-10As usage time increases, the tape 28 will gradually become completely contaminated with dust. At this point, the mounting plate 4 needs to be removed from the symmetrical connecting pipe 3, and the cover plate 15 and cleaning plate 14 separated. The old tape 28 should then be removed from the outer walls of the first winding cylinder 29, the second winding cylinder 30, and the rotating cylinder 25, and replaced with a new tape 28. This ensures that the tape 28 can continuously maintain its cleaning ability for the filter screen 7. The bottom of the inner cavity of the fixing plate 5, near the driven plate 31, has symmetrical grooves 35. Symmetrical insertion rods 32 are fixedly connected to the lower center of the annular plate 9. A limiting block 33 is elastically connected to the inner cavity of the insertion rod 32 near the center of the annular plate 9. A slope is provided on the lower part of the limiting block 33 away from the insertion rod 32. When the annular plate 9 moves the symmetrical insertion rods 32 and the limiting block 33 closer to the fixing plate 5, the slope of the limiting block 33 will first... The limiting block 33 retracts into the inner cavity of the insertion rod 32 under the pressure of the side wall of the groove 35. A limiting groove 40 is opened on the side of the lower part of the inner cavity of the groove 35 near the center of the annular plate 9. When the side of the insertion rod 32 away from the annular plate 9 is in contact with the side wall of the inner cavity of the groove 35, the limiting block 33 will pop out from the inner cavity of the insertion rod 32 under the action of elasticity, and thus be locked in the limiting groove 40 to limit and fix the annular plate 9 and the mounting plate 4. With the cooperation of the insertion rod 32 and the limiting groove 40, when fixing the mounting plate 4 and the annular plate 9, it is only necessary to push the mounting plate 4 horizontally close to the position of the fixing plate 5. When the side walls of the mounting plate 4 and the fixing plate 5 are in contact with each other, the installation and fixing of the annular plate 9 and the mounting plate 4 can be completed. A sealing gasket is set at the connection between the mounting plate 4 and the fixing plate 5 to ensure the sealing between the mounting plate 4, the fixing plate 5 and the connecting pipe 3.

[0037] Please see Figure 8-10 A driven groove 34 is provided on the side of the inner cavity of the fixed plate 5 away from the mounting plate 4. The driven groove 34 is located between the symmetrical insertion rods 32, and the horizontal width of the driven groove 34 is the same as the spacing between the symmetrical insertion rods 32. The driven plate 31 is slidably connected to the inner cavity of the driven groove 34. A through groove is provided on the side of the annular plate 9 near the fixed plate 5 to slide with the driven plate 31. The end of the driven plate 31 near the driven groove 34 is elastically connected to the inner cavity sidewall of the driven groove 34 by a spring. The end of the driven plate 31 near the driven groove 34 is arc-shaped. When the driven plate 31 moves toward the inner wall of the driven groove 34, the arc-shaped outer wall will contact the end of the limiting block 33, thereby pushing the limiting block 33 toward the inner cavity of the plug rod 32, so that the limiting block 33 is disengaged from the inner cavity of the limiting groove 40. At this time, by pulling the mounting plate 4 horizontally, the mounting plate 4 and the annular plate 9 can be disassembled simultaneously from the symmetrical connecting pipes 3, which facilitates the inspection or replacement of the tape 28 and the filter screen 7.

[0038] Please see Figure 8 , Figure 9 and Figure 11 An arc-shaped inclined edge 38 is formed on the side of the driven plate 31 near the center of the annular plate 9. An arc-shaped groove 36 is formed on the lower part of the driven plate 31 near the adjusting rod 23. The side of the contact rod 24 away from the cleaning plate 14 slides in cooperation with the arc-shaped groove 36. A baffle 39 is fixedly connected to the upper end of the arc-shaped inclined edge 38. A one-way rotating plate 37 is attached to the inner cavity of the arc-shaped groove 36 away from the arc-shaped inclined edge 38. One end of the one-way rotating plate 37 near the baffle 39 is fixedly connected to the middle of the arc-shaped inclined edge 38, and the other end of the one-way rotating plate 37 is attached to the side of the arc-shaped groove 36 near the fixed plate 5. Thus, the one-way rotating plate 37... The arc-shaped groove 36 is sealed in one direction. When the contact rod 24 rotates clockwise, the side of the contact rod 24 away from the cleaning plate 14 enters the inner cavity of the arc-shaped groove 36 after approaching the driven plate 31, without contacting the outer wall of the driven plate 31. When the contact rod 24 slides through the inner cavity of the arc-shaped groove 36 and contacts the side of the one-way rotating plate 37 near the arc-shaped groove 36, it will push the one-way rotating plate 37 to rotate toward the center of the annular plate 9. After the contact rod 24 separates from the one-way rotating plate 37, the one-way rotating plate 37 automatically resets under the action of elasticity, and seals the arc-shaped groove 36 in one direction again.

[0039] When the adjusting rod 23 drives the contact rod 24 to rotate counterclockwise, the contact rod 24 separates from the fixed rod 16 and does not drive the cleaning plate 14 to rotate counterclockwise. After the contact rod 24 rotates counterclockwise and approaches the driven plate 31, the one-way rotating plate 37 will then prevent the contact rod 24 from entering the inner cavity of the arc groove 36. At this time, the contact rod 24 will contact the arc-shaped inclined edge 38 through the one-way rotating plate 37, thereby pushing the driven plate 31 towards the inner cavity of the driven groove 34. Then, the movement of the driven plate 31 causes the limiting block 33 to retract into the inner cavity of the insertion rod 32. The baffle 39 restricts the rotation of the contact rod 24 after it contacts the baffle 39, thereby ensuring that the limiting block 33 will not be affected during the disassembly and removal of the mounting plate 4 and the annular plate 9. The filter screen 7 is cleaned by rotating the adjusting rod 23 and the contact rod 24 clockwise while the compressor 1 is working, ensuring that the dust does not fall off the filter screen 7. During the dust cleaning process, the tape 28 is continuously wrapped around the outer wall of the first winding cylinder 29, so that the tape 28 has the same efficient cleaning ability for dust on all parts of the outer wall of the filter screen 7 during the clockwise rotation. The adjusting rod 23 and the contact rod 24 are driven to rotate counterclockwise by the servo motor 22, which drives the driven plate 31 to push the limiting block 33 into the inner cavity of the plug rod 32, releasing the limiting effect of the fixing plate 5 on the mounting plate 4 and the annular plate 9, and facilitating the disassembly and installation of the mounting plate 4 and the annular plate 9.
