Description

Technical Field

[0001] This utility model relates to the field of sheet material cleaning technology, specifically a hollow plastic sheet cleaning device. Background Technology

[0002] Hollow plastic sheets are made of modern chemical HDPE and HDPP materials. They are a new type of material that is lightweight (hollow structure), non-toxic, non-polluting, waterproof, shockproof, anti-aging, corrosion-resistant, and available in a variety of colors. Compared with cardboard products, hollow plastic sheets have advantages such as moisture resistance, corrosion resistance, and lighter weight, making them a better alternative to cardboard. When using hollow plastic sheets, they are usually placed in a cleaning device to clean their outer surface.

[0003] The prior art patent CN218282805U discloses a surface cleaning device for processing plastic sheets. A fixing mechanism secures the plastic sheets, facilitating cleaning by a brushing mechanism. The sheet is placed in the center of a fixing block, and a screw is rotated to clamp it. The brushing mechanism can clean two sheets simultaneously, improving work efficiency. A drive motor rotates the main shaft, which, through a drive gear and a driven gear, causes two auxiliary shafts to rotate, using brushes to clean the sheets. However, during use, workers must first remove the cleaned sheet and then place the sheet to be cleaned, requiring the equipment to be stopped and waiting, wasting considerable time and resulting in low work efficiency. Further improvement is needed. Therefore, we propose a hollow plastic sheet cleaning device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-5This utility model provides a technical solution: a hollow plastic sheet cleaning device, including two support plates 1, with a support frame fixedly installed at the bottom of both support plates 1. Multiple mounting holes are opened on the sides of both support plates 1, and a support shaft is rotatably installed in every two corresponding mounting holes. Conveyor rollers 2 are fixedly sleeved on the multiple support shafts. A protective box 3 is fixedly installed on the side of one of the support plates 1, and a conveyor motor 4 is fixedly installed on the side of the protective box 3. The output end of the conveyor motor 4 extends into the protective box 3 and is fixedly installed with a drive shaft 5. Multiple first bevel gears 15 are fixedly sleeved on the drive shaft 5. A second bevel gear 16 is fixedly installed at one end of each of the multiple support shafts. The multiple first bevel gears 15 mesh with the multiple second bevel gears 16 respectively. A shield is fixedly installed on the top of both support plates 1. The shield box 6 has a collection box 7 fixedly installed at the bottom of the two support plates 1. Multiple spray pipes 8 are fixedly installed on the top inner wall of the shield box 6. Multiple rinsing heads are fixedly installed at the bottom of the multiple spray pipes 8. A cleaning motor 9 is fixedly installed on the side of the other support plate 1. The output end of the cleaning motor 9 passes through the support plate 1 and is fixedly installed with a first rotating shaft 10. A lower cleaning brush 11 is fixedly sleeved on the first rotating shaft 10. A U-shaped frame 12 is set directly above the lower cleaning brush 11. Rotating holes are opened on the two opposite sides of the U-shaped frame 12. A second rotating shaft 13 is rotatably installed in the two rotating holes. An upper cleaning brush 14 is fixedly sleeved on the second rotating shaft 13. A pulley drive unit for making the second rotating shaft 13 rotate synchronously is connected to the first rotating shaft 10. An adapter adjustment component for controlling the up and down movement of the U-shaped frame 12 is provided on the shield box 6.

[0024] With the above structure, when the conveyor motor 4 is started, it drives the drive shaft 5 to rotate. The rotation of the drive shaft 5 drives multiple support shafts to rotate synchronously through the first bevel gear 15 and the second bevel gear 16, which in turn drives multiple conveyor rollers 2 to rotate together. The rotation of the conveyor rollers 2 transports the hollow plastic sheet to be cleaned into the shielding box 6. At this time, the hollow plastic sheet can be sprayed and rinsed through the spray pipe 8 and the rinsing head. At the same time, the cleaning motor 9 is started. The operation of the cleaning motor 9 drives the first shaft 10 and the lower cleaning brush 11 to rotate. The first shaft 10 drives the second shaft 13 and the upper cleaning brush 14 to rotate synchronously through the pulley transmission unit, which can rinse the upper and lower surfaces of the hollow plastic sheet. After cleaning, the hollow plastic sheet is transported to the outside of the shielding box 6 by the conveyor rollers 2. This achieves the purpose of continuously cleaning multiple hollow plastic sheets without stopping the equipment, saving a lot of time and improving work efficiency.

[0025] like Figure 2 , Figure 4 and Figure 5As shown, the belt drive unit includes a driving pulley 17 fixedly sleeved on the first rotating shaft 10, a driven pulley 18 fixedly sleeved on the second rotating shaft 13, a mounting block 19 fixedly installed on the side of one of the support plates 1, a hexagonal sliding hole opened on the side of the mounting block 19, a hexagonal sliding rod 20 slidably installed in the hexagonal sliding hole, a U-shaped block 21 fixedly installed on one end of the hexagonal sliding rod 20, a connecting shaft rotatably installed on the inner walls of the two mutually distant sides of the U-shaped block 21, a tension pulley 22 fixedly sleeved on the connecting shaft, a transmission belt 23 adapted to be fitted on the driving pulley 17, the driven pulley 18 and the tension pulley 22, a fixing plate 24 fixedly installed on the other end of the hexagonal sliding rod 20, and a tension spring 25 fixedly installed on the side of the mounting block 19 and the fixing plate 24. Under the elastic force of the tension spring 25, a thrust is applied to the fixed plate 24 to move it away from the drive pulley 17. This, in turn, drives the tension pulley 22 to move away from the drive pulley 17 through the hexagonal slide bar 20, U-shaped block 21 and connecting shaft. This keeps the transmission belt 23 in a taut state. When the first shaft 10 rotates, it drives the drive pulley 17 to rotate. The rotation of the drive pulley 17 drives the driven pulley 18 to rotate through the transmission belt 23, thus achieving the purpose of driving the second shaft 13 to rotate synchronously and playing the role of transmission.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the adapter adjustment assembly includes a bidirectional lead screw 26 rotatably mounted on the inner side wall of the shielding box 6. Two moving blocks 27 are threaded onto the bidirectional lead screw 26. The bottom of each moving block 27 is rotatably connected to an inclined rotating rod 28. The bottom ends of each inclined rotating rod 28 are rotatably connected to the top of the U-shaped frame 12. One end of the bidirectional lead screw 26 extends to the outside of the shielding box 6 and is fixedly mounted with an adjustment knob 29. A horizontal guide rod 30 is fixedly mounted on the inner side wall of the shielding box 6. Both moving blocks 27 are slidably sleeved on the horizontal guide rod 30. When the adjustment knob 29 is turned, the bidirectional lead screw 26 will rotate. With the cooperation of the horizontal guide rod 30, the rotation of the bidirectional lead screw 26 will drive the two moving blocks 27 to move horizontally in opposite directions at the same time. The horizontal movement of the moving blocks 27 will drive the tilting rod 28 to tilt and rotate up and down. The tilting rod 28 will tilt and rotate up and down, which will drive the U-shaped frame 12 to move up and down, and thus drive the upper cleaning brush 14 to move up and down together. This achieves the purpose of adapting to cleaning hollow plastic sheets of different thicknesses, and improves the applicability of the device.

[0027] like Figure 1 and Figure 4As shown, a protrusion is fixedly installed on the side of the shielding box 6. A sliding hole is opened on the top of the protrusion, and a fixing pin 31 is slidably installed in the sliding hole. Multiple fixing holes are evenly opened on the circumference of the adjusting knob 29, and the bottom end of the fixing pin 31 extends into one of the fixing holes. When the fixing pin 31 is moved up or down to move out of or into the fixing hole, the adjusting knob 29 can be loosened or fixed so that it cannot be rotated. This effectively reduces the possibility of the height of the upper cleaning brush 14 changing due to accidental contact with the adjusting knob 29 during use, ensuring stable and reliable operation.

[0028] Working principle: In use, the hollow plastic sheet to be cleaned is placed on the conveyor roller 2. The conveyor motor 4 and the cleaning motor 9 are started. The operation of the conveyor motor 4 drives the drive shaft 5 to rotate. The rotation of the drive shaft 5 drives multiple support shafts to rotate synchronously through the first bevel gear 15 and the second bevel gear 16, which in turn drives multiple conveyor rollers 2 to rotate together, conveying the hollow plastic sheet to be cleaned into the shielding box 6. At this time, the hollow plastic sheet can be sprayed and rinsed through the spray pipe 8 and the flushing head. At the same time, the operation of the cleaning motor 9 drives the first rotating shaft 10 and the lower cleaning brush 11 to rotate. The machine will drive the driven pulley 18 to rotate through the active pulley 17, mounting block 19, hexagonal slide bar 20, fixing plate 24, tension spring 25, U-shaped block 21, connecting shaft, tension pulley 22 and transmission belt 23. This will drive the second shaft 13 and the upper cleaning brush 14 to rotate synchronously, and wash the upper and lower surfaces of the hollow plastic sheet. After cleaning, the hollow plastic sheet will be transported to the shielding box 6 by the conveyor roller 2. This achieves the purpose of continuously cleaning multiple hollow plastic sheets without stopping the machine, saving a lot of time and improving work efficiency.

[0029] When the height of the upper cleaning brush 14 needs to be adjusted, first pull the fixing pin 31 upwards until it moves out of the fixing hole, and release the adjustment knob 29. At this time, the adjustment knob 29 can be rotated. The rotation of the adjustment knob 29 will drive the bidirectional lead screw 26 to rotate. With the cooperation of the horizontal guide rod 30, the rotation of the bidirectional lead screw 26 will drive the U-shaped frame 12 to move up and down through the moving block 27 and the tilting rod 28, which will in turn drive the upper cleaning brush 14 to move up and down together to adjust its height. After the adjustment is completed, press the fixing pin 31 downwards until it is inserted into the fixing hole, and fix the adjustment knob 29 so that it cannot be rotated.
