Description
Technical Field
[0001] This invention belongs to the field of non-destructive cleaning technology, specifically a method and apparatus for efficient cleaning of circular rollers. Background Technology
[0002] In PVDD continuous coating equipment, the conveyor rollers are quickly coated with material. The material adheres to the surface of the rollers, affecting the product's precision and usability. Therefore, it is necessary to periodically peel off the surface material.
[0003] Existing methods for cleaning the cured coating on the surface of cylindrical rollers typically involve laser and mechanical grinding. This method is inefficient, time-consuming, labor-intensive, and prone to damaging the roller surface. Therefore, this invention combines water jet design with a device for efficient and rapid cleaning of cylindrical rollers. By adjusting the water pressure range and selecting the appropriate abrasive material, different types of deposits can be cleaned efficiently. Existing water jet devices spray a single stream of high-pressure water from the nozzle, which makes direct contact with the roller, resulting in a small contact area between the water jet and the roller. This leads to poor peeling effect and slow speed. Furthermore, the nozzle size of existing water jets is fixed, meaning that when replacing with longer rollers, the water jet cannot completely cover the entire surface of the roller, resulting in incomplete cleaning of the cylinder. Summary of the Invention

[0010] Preferably, the recycling mechanism includes a slurry collector, which is fixedly installed on the right side of the upper surface of the platform.

[0011] Preferably, a pressure-reducing groove is provided on one side of each of the plurality of pressure-reducing plates, the bottom surface of the pressure-reducing groove on the left side is lower than the top surface of the pressure-reducing groove on the right side, and the height of the pressure-reducing groove is less than the gap distance between two adjacent pressure-reducing plates.
[0012] A method for efficiently cleaning a circular roller includes the following steps:
[0013] S1: Start the feeding mechanism, which delivers pressurized and mixed water to the inside of the tank.
[0014] S2: The high-pressure water containing abrasive particles that flows into the housing is depressurized layer by layer by multiple pressure reducing plates, and then flows out from the nozzle of the nozzle along the tangent direction of the workpiece roller between two adjacent guide plates. At the same time, the roller drive motor is started to make the workpiece roller rotate, and the high-pressure water carrying abrasive particles cleans the adhering substances on the surface of the workpiece roller.
[0015] S3: Finally, the water carrying impurities after cleaning the surface of the workpiece roller flows through the slurry collector and slurry pipe into the interior of the slurry recovery tank.
[0016] The beneficial effects of this invention are as follows:
[0017] 1. This invention pressurizes the water flowing into the high-pressure water pipe by setting up a water pump, a plunger booster pump, a hydraulic pump, and an energy storage device. Simultaneously, abrasive particles from inside the abrasive box flow into the high-pressure water pipe through the abrasive pipe and mix with the high-pressure water inside. The high-pressure water containing abrasive particles inside the box is depressurized layer by layer by multiple pressure-reducing plates, causing the water pressure between the multiple pressure-reducing plates, adjacent partitions, and the nozzle to decrease sequentially from left to right. Then, the high-pressure water containing abrasive particles between adjacent guide plates inside the nozzle is sprayed out along the upper surface of the guide plates and interacts with the workpiece roller. The curved surfaces are tangent to each other. At the same time, because the pressure of the multiple water streams flowing out between the two adjacent guide plates increases from left to right, when the water stream on the left comes into contact with the water stream on the right, the high-pressure water stream on the right hits the low-pressure water stream on the left, changes direction, bends downward, and becomes tangent to the curved surface of the workpiece roller again. This converts the line tangency between the water stream and the workpiece roller into surface tangency, thereby improving the efficiency and speed of the water stream removing impurities from the surface of the workpiece roller. Then, the roller drive motor is started, and the roller drives the workpiece roller to rotate, so that the high-pressure water with abrasive particles removes impurities from the entire curved surface of the workpiece roller.
[0018] 2. This invention, when the thickness of the sheet metal or the coating thickness of the workpiece needs to be increased, activates the telescopic rod. The telescopic end of the telescopic rod moves to the left, and through the push block, roller seat, and main shaft, pushes the workpiece roller upward, thereby increasing the distance between the bottom of the workpiece roller and the workpiece. This changes the coating thickness of the workpiece or allows for the replacement of workpieces with different thicknesses, thus enabling the processing of workpieces with different thicknesses and coatings of different thicknesses. Furthermore, when the width of the workpiece increases, the driven pulley and limit ring are first removed from the main shaft, then the sliding seat is moved away from the telescopic rod, and then the main shaft and workpiece roller are moved from the sliding seat... The middle part of the seat is unloaded and replaced with a workpiece roller of the same diameter but larger width. At this time, due to the increase in the width of the workpiece roller, the sliding seat drives the valve plate to move away from the telescopic rod through the roller seat and valve block, thereby increasing the width of the nozzle. This ensures that the high-pressure water sprayed from the nozzle with abrasive particles always covers the entire curved surface of the workpiece roller, while preventing the sprayed high-pressure water with abrasive particles from exceeding the curved surface of the workpiece roller. This avoids the problem of some areas of the workpiece roller not being cleaned when the diameter of the workpiece roller increases, as the nozzle size remains unchanged. It also avoids the problem of wasting water resources and abrasive particles when the workpiece roller diameter decreases. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] like Figures 1 to 6As shown, this embodiment of the invention provides a method and apparatus for efficient cleaning of a circular roller, including a platform 1. A side plate 101 is fixedly installed on the rear side of the upper surface of the platform 1. Support plates 2 are symmetrically fixedly installed in the middle of the upper surface of the platform 1. Mounting plates 3 are fixedly installed on the upper surfaces of the two support plates 2. A motor base 301 is fixedly installed on the front of the mounting plate 3. Stop blocks 4 are symmetrically fixedly installed on the upper surface of the mounting plate 3. A platform 5 is fixedly installed on the upper surface of the two stop blocks 4. A guide groove is provided in the middle of the platform 5. A support platform 6 is fixedly installed on the left side of the middle of the upper surface of the platform 5. A housing 7 is provided on the upper surface of the support platform 6. A gap is left between the upper surface of the support platform 6 and the lower surface of the housing 7. A nozzle 8 is fixedly installed on the right side of the housing 7. Pressure reducing plates 9 are fixedly installed at equal intervals on the bottom surface of the inner cavity of the nozzle 8. Multiple pressure reducing plates 9 are fixedly installed on the bottom surface of the inner cavity of the nozzle 8. Pressure reducing grooves 901 are provided on one side of the plate 9. The bottom surface of the pressure reducing groove 901 on the left side is lower than the top surface of the pressure reducing groove 901 on the right side. The height of the pressure reducing groove 901 is less than the gap distance between two adjacent pressure reducing plates 9. By setting multiple pressure reducing grooves 901, the resistance of water flow through the pressure reducing grooves 901 is increased, so that the water flow pressure on the left side of the pressure reducing plate 9 is greater than the water flow pressure on the right side. As a result, the water flow pressure between two adjacent partitions 10 decreases from left to right, and the pressure of multiple water flows flowing out between two adjacent guide plates 11 increases from left to right. Thus, when the water flow on the left side comes into contact with the water flow on the right side, the high-pressure water flow on the right side hits the low-pressure water flow on the left side, causing it to change direction and bend downwards to be tangent to the curved surface of the workpiece roller 1402 again, thus removing impurities from the surface of the workpiece roller 1402.
[0028] Multiple pressure-reducing plates 9 are each fixedly mounted with a baffle 10 at their top. A guide plate 11 is fixedly mounted on the upper right side of each baffle 10. Both the pressure-reducing plates 9 and the guide plates 11 are made of wear-resistant materials, specifically titanium alloy. This prevents the pressure-reducing plates 9 and 11 from being abraded by grinding particles in the water flow, thus avoiding drastic changes in the size and shape of the pressure-reducing tank 901 and the upper surface of the guide plates 11. This causes changes in the water pressure between adjacent baffles 10 and lowers the extended surface of the guide plates 11, allowing water containing grinding particles flowing from the upper surface of the guide plates 11 to contact the workpiece roller 1402, leading to wear of the workpiece roller 1402 and consequently reducing coating accuracy. The middle of the stage 5 is equipped with... The system has a drive mechanism, a lifting mechanism in the middle of the left side of the right stop block 4, a roller mechanism movably connected in the middle of the drive mechanism, the extended surface of the upper surface of multiple guide plates 11 is tangent to the outer curved surface of the roller mechanism, a feeding mechanism is provided between the left side of the upper surface of the platform 1 and the housing 7, and a recycling mechanism is provided between the right side of the upper surface of the platform 1 and the roller mechanism. The recycling mechanism includes a slurry collector 1601, which is fixedly installed on the right side of the upper surface of the platform 5. The slurry collector 1601 slides in contact with the workpiece roller 1402. A slurry pipe 1602 is fixedly installed in front of the slurry collector 1601, and a slurry recycling box 1603 is fixedly installed at the bottom end of the slurry pipe 1602. The slurry pipe 1602 is fixedly installed on the upper surface of the platform 1.
[0029] like Figures 1 to 6 As shown, the drive mechanism includes two sliding seats 1201, which are symmetrically slidably sleeved in the middle of the platform 5. A roller seat 1202 is slidably sleeved in the middle of the upper surface of the sliding seat 1201. A fixing block 1203 is fixedly installed on the left side of the roller seat 1202. A guide rail 1204 is slidably sleeved on the upper part of the two fixing blocks 1203. The upper surface of the guide rail 1204 is fixedly connected to the nozzle 8. A valve block 1205 is fixedly installed at the top of the roller seat 1202. Multiple valve plates 1206 are fixedly installed at equal intervals on the left side of the valve block 1205. The valve plates 1206 are slidably sleeved with the nozzle 8 and the guide plate 11. The right side of the middle of the upper surface of the support platform 6 A telescopic sleeve 1207 is fixedly installed. The top of the telescopic end of the telescopic sleeve 1207 is fixedly connected to the bottom surface of the guide rail 1204. By providing the telescopic sleeve 1207, the roller seat 1202 can drive the nozzle 8 to move up and down relative to the platform 5 through the fixed block 1203 and the guide rail 1204. At the same time, the telescopic sleeve 1207 restricts the nozzle 8 to move back and forth through the guide rail 1204. This prevents the sliding seat 1201 from driving the valve plate 1206 to move back and forth through the valve block 1205, which would cause the nozzle 8 to move back and forth, resulting in a change in the position of the nozzle 8. This would cause the high-pressure water jet sprayed from the nozzle 8 to detach from the surface of the workpiece roller 1402, resulting in a poor cleaning effect.
[0030] like Figure 3As shown, the lifting mechanism includes a telescopic rod 1301, which is fixedly installed in the middle of the left side of the right stop block 4. A push block 1302 is fixedly installed at the telescopic end of the telescopic rod 1301. The upper surface of the push block 1302 slides in contact with the bottom surface of the roller seat 1202. The upper surface of the push block 1302 is a smooth inclined surface, and the lower surface of the fixed block 1203 is a smooth inclined surface. This allows the push block 1302 to move to the left and push the fixed block 1203 to move upward. The fixed block 1203 then drives the workpiece roller 1402 to move upward, thereby changing the distance between the bottom end of the workpiece roller 1402 and the upper surface of the workpiece, increasing the thickness of the film layer on the workpiece surface. This allows for adjusting the distance between the bottom end of the workpiece roller 1402 and the workpiece according to the thickness of the film layer, improving the versatility of the workpiece roller 1402 and avoiding the need to replace workpiece rollers 1402 of different diameters.
[0031] like Figure 1 , Figure 2 , Figure 4 As shown, the roller mechanism includes a main shaft 1401, which is movably sleeved in the middle of two fixed blocks 1203. A workpiece roller 1402 is fixedly installed in the middle of the main shaft 1401. The workpiece roller 1402 is made of a high-hardness material to prevent small amounts of water flow and abrasive particles from contacting the curved surface of the workpiece roller 1402, thus avoiding wear and reduced precision of the workpiece roller 1402, resulting in a decrease in the film thickness of the final workpiece and a deterioration in the quality of the finished product. The extended surface of the upper surface of the guide plate 11 is tangent to the outer curved surface of the workpiece roller 1402, thereby minimizing contact between the water flow and abrasive particles exiting the nozzle 8 and the surface of the workpiece roller 1402. The precision of the workpiece roller 1402 is reduced, and at the same time, the sticky residue on the curved surface of the workpiece roller 1402 is removed to keep the curved surface of the workpiece roller 1402 smooth and clean, so as to avoid the reduction of the precision of the curved surface of the workpiece roller 1402. Limiting rings 1403 are symmetrically fixedly installed on the front and rear sides of the workpiece roller 1402. The limiting rings 1403 slide in contact with the fixed block 1203. A passive pulley 1404 is fixedly installed at the front end of the main shaft 1401. A roller drive motor 1405 is fixedly installed on the upper surface of the motor base 301. An active pulley 1406 is fixedly installed at the output end of the roller drive motor 1405. A belt 1407 is sleeved between the curved surface of the passive pulley 1404 and the curved surface of the active pulley 1406.
[0032] like Figure 1As shown, the feeding mechanism includes a water tank 1501, which is fixedly installed in the middle of the upper surface of the platform 1. A water pump 1502 is fixedly installed at the output end on the left side of the water tank 1501, and a water filter 1503 is fixedly installed at the output end on the left side of the water pump 1502. The water filter 1503 has multiple layers of filter membranes in the middle, thereby filtering the water in the middle of the water tank 1501 to avoid hard particulate impurities and contaminants in the water from causing wear and contamination on the surface of the workpiece roller 1402. A first connector 1 is installed at the output end of the water filter 1503. 504. A hydraulic pump 1505 is fixedly installed on the left side of the upper surface of platform 1. A reversing valve 1506 is fixedly installed at the output end of the hydraulic pump 1505. A plunger booster pump 1507 is fixedly installed on the right side of the upper surface of platform 1. The output end of the reversing valve 1506 is fixedly connected to the input end of the plunger booster pump 1507. A first check valve 1508 is fixedly installed at the input end of the plunger booster pump 1507. By setting the first check valve 1508, water inside the plunger booster pump 1507 is prevented from flowing to the first check valve 1508 when the water pump 1502 is de-energized. Internal backflow is prevented. The input end of the first one-way valve 1508 is fixedly connected to the output end of the first connector 1504. The output end of the plunger booster pump 1507 is fixedly mounted with a second connector 1509. The output end of the second connector 1509 is fixedly mounted with a second one-way valve 1510. The output end of the second one-way valve 1510 is fixedly mounted with an energy storage device 1511. By setting the second one-way valve 1510, backflow of water inside the energy storage device 1511 into the second connector 1509 is prevented. The output end of the energy storage device 1511 is fixedly mounted with... A high-pressure water pipe 1512 is fixedly installed on the upper surface of the side plate 101, and an abrasive box 1513 is fixedly installed on it. The bottom surface of the abrasive box 1513 is higher than the water pump 1502, so that the abrasive particles inside the abrasive box 1513 automatically flow into the interior of the high-pressure water pipe 1512 under the action of gravity and mix with the water inside the high-pressure water pipe 1512. An abrasive tube 1514 is fixedly installed at the output end of the abrasive box 1513, and the output end of the abrasive tube 1514 is fixedly connected to the high-pressure water pipe 1512. The output end of the high-pressure water pipe 1512 is fixedly installed in the middle of the housing 7.
[0033] like Figures 1 to 6 As shown, a method for efficiently cleaning a circular roller includes the following steps:
[0034] S1: Start the feeding mechanism, which delivers pressurized and mixed water to the interior of the housing 7.
[0035] S2: The high-pressure water containing abrasive particles flowing into the housing 7 is depressurized layer by layer by multiple pressure reducing plates 9, and then flows out from the nozzle of the nozzle 8 along the tangential direction of the workpiece roller between two adjacent guide plates 11. At the same time, the roller drive motor 1405 is started, causing the workpiece roller 1402 to rotate. The high-pressure water carrying abrasive particles cleans the adhering substances on the surface of the workpiece roller. The rotation direction of the workpiece roller 1402 is opposite to the flow direction of the water, thereby increasing the impact force between the adhering substances on the surface of the workpiece roller 1402 and the water, and improving the cleaning efficiency.
[0036] S3: Finally, the water carrying impurities after cleaning the surface of the workpiece roller flows through the slurry collector 1601 and the slurry pipe 1602 into the slurry recovery tank 1603.
[0037] Working principle:
[0038] In use, water pump 1502 is started, which drives the water in water tank 1501 to water filter 1503. Water filter 1503 filters impurities in the water. The filtered water in water filter 1503 flows into first connector 1504. The water in first connector 1504 flows into plunger booster pump 1507 through first check valve 1508. At the same time, hydraulic pump 1505 is started. Hydraulic pump 1505 absorbs water from plunger booster pump 1507 through reversing valve 1506 and pressurizes the water. Then, it flows again through reversing valve 1507. 6. The water is injected into the plunger booster pump 1507 to pressurize the water inside the pump. The pressurized high-pressure water flows into the second connector 1509. The high-pressure water inside the second connector 1509 flows into the energy storage device 1511 through the second one-way valve 1510. The high-pressure water inside the energy storage device 1511 flows into the high-pressure water pipe 1512. The grinding particles inside the abrasive box 1513 flow into the high-pressure water pipe 1512 through the abrasive pipe 1514 and mix with the high-pressure water inside the high-pressure water pipe 1512. Then, the high-pressure water containing the grinding particles flows into... Inside the housing 7, high-pressure water containing abrasive particles is depressurized layer by layer by multiple pressure-reducing plates 9, causing the water pressure between adjacent partitions 10 and nozzles 8 to decrease from left to right. Then, inside nozzle 8, the high-pressure water containing abrasive particles between adjacent guide plates 11 flows along the upper surface of guide plates 11 and is tangential to the curved surface of workpiece roller 1402. Simultaneously, the pressure of multiple water streams flowing out between adjacent guide plates 11 increases from left to right. Therefore, when the water stream on the left comes into contact with the water stream on the right, the high-pressure water stream on the right impacts the low-pressure water stream on the left, changing direction and bending downwards to contact the workpiece roller 1402. The curved surface is tangent again, thus converting the line tangency between the water flow and the workpiece roller 1402 into a surface tangency, thereby improving the efficiency and speed of the water flow removing impurities from the surface of the workpiece roller 1402. Then, the roller drive motor 1405 is started. The output shaft of the roller drive motor 1405 drives the roller drive motor 1405 to rotate. The roller drive motor 1405 drives the belt 1407 to rotate through the drive pulley 1406. The belt 1407 drives the main shaft 1401 to rotate. The main shaft 1401 drives the workpiece roller 1402 to rotate, thereby removing impurities from the entire curved surface of the workpiece roller 1402 with high-pressure water containing abrasive particles.
[0039] When the thickness of the sheet material or the coating thickness of the workpiece needs to be increased, the telescopic rod 1301 is activated. The telescopic end of the telescopic rod 1301 pushes the push block 1302 to move to the left. The push block 1302 pushes the roller seat 1202 to move upward. The roller seat 1202 pushes the main shaft 1401 to move upward. The main shaft 1401 pushes the workpiece roller 1402 to move upward, thereby increasing the distance between the bottom end of the workpiece roller 1402 and the workpiece, changing the coating thickness of the workpiece or replacing the workpiece with a different thickness. In addition, while the roller seat 1202 moves upward, the roller seat 1202 drives the fixed block 1203 to move upward. The fixed block 1203 drives the guide rail 1204 to move upward. The guide rail 1204 drives the nozzle 8 to move upward, so that the position between the nozzle 8 and the workpiece roller 1402 always remains relatively stationary. This ensures that the high-pressure water sprayed from the nozzle 8 with abrasive particles is always tangent to the curved surface of the workpiece roller 1402, thereby enabling the processing of workpieces of different thicknesses and the processing of coatings of different thicknesses.
[0040] Furthermore, when the width of the workpiece increases, first remove the driven pulley 1404 and the limiting ring 1403 from the main shaft 1401. Then, move the sliding seat 1201 away from the telescopic rod 1301. Next, unload the main shaft 1401 and the workpiece roller 1402 from the middle of the sliding seat 1201 and replace it with a workpiece roller 1402 of the same diameter but larger width. At this time, due to the increased width of the workpiece roller 1402, the sliding seat 1201 drives the roller seat 1202 to move away from the telescopic rod 1301. The roller seat 1202 drives the valve block 1205 to move away from the telescopic rod 1301. The valve block 1205 moves the valve plate 1206 away from the telescopic rod 1301, thereby increasing the width of the nozzle 8. This ensures that the high-pressure water sprayed from the nozzle 8, containing abrasive particles, always covers the entire curved surface of the workpiece roller 1402. At the same time, it prevents the sprayed high-pressure water containing abrasive particles from exceeding the curved surface of the workpiece roller 1402. This avoids the problem of some areas of the workpiece roller 1402 not being cleaned when the diameter of the workpiece roller 1402 increases, as the nozzle 8 has a fixed nozzle size. It also avoids the problem of wasting water resources and abrasive particles when the diameter of the workpiece roller 1402 decreases.
