Description

Technical Field

[0001] This utility model relates to the technical field of plastic sheet processing equipment, specifically to a surface cleaning device for plastic sheets. Background Technology

[0002] During the production, processing, and storage of plastic sheets, the surface is easily contaminated with dust, oil, debris, and other impurities. If not cleaned in time, it will affect the quality of subsequent processing, such as the effect of lamination, printing, and spraying. Existing equipment mostly adopts a single fixed mode, which requires the plastic sheet to be fixed by clamps and other components before cleaning. When it is necessary to clean the other side, it is necessary to manually release the fixation, flip the sheet, and re-fix it. The whole process not only consumes a lot of manpower and time, but is also prone to affecting the cleaning accuracy due to positioning deviation, and may even lead to deformation of the sheet or secondary contamination. Frequent manual intervention will prolong the cleaning cycle and increase labor intensity and production costs. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1 to 7 This utility model provides a technical solution: a surface cleaning device for plastic sheets, including a cleaning frame 1, a gantry-shaped movable frame 2 slidably fitted above the cleaning frame 1, an electric push rod 3 fixedly installed in the middle of the movable frame 2, a cleaning frame 4 located below the horizontal plate of the movable frame 2 fixedly connected to the end of the telescopic shaft of the electric push rod 3, a clamping frame 5 rotatably fitted between the inner walls of the two sides of the through groove in the middle of the cleaning frame 1, an adjustment component 6 provided between the clamping frame 5 and the cleaning frame 1, sliding grooves 7 opening downward on both sides above the clamping frame 5, two longitudinal plates of the movable frame 2 slidingly fitted with the sliding grooves 7 on both sides, a first motor 8 fixedly installed on one side of the cleaning frame 1, a screw 9 fixedly connected to the output shaft of the first motor 8 through one of the sliding grooves 7, the screw 9 through one of the longitudinal plates of the movable frame 2 and threadedly fitted therewith.

[0025] In this embodiment, a water storage tank 10 is fixedly installed on one side of the cleaning frame 1, and a first pump body 11 is fixedly installed on the water storage tank 10. The inlet of the first pump body 11 is connected to the outlet of the water storage tank 10. A spray box 12 is fixedly connected to one side of the cleaning frame 4, and a first connecting hose 13 is fixedly connected between the inlet of the spray box 12 and the outlet of the first pump body 11. A foam storage box 14 is fixedly installed on one side of the cleaning frame 1, and a second pump body 15 is fixedly installed on the foam storage box 14. The inlet of the second pump body 15 is connected to the outlet of the foam storage box 14. A spray box 1 is fixedly connected to one side of the cleaning frame 4. 6. A second connecting hose 17 is fixedly connected between the liquid inlet of the spray box 16 and the liquid outlet of the second pump body 15. A second motor 18 is fixedly connected to the outer wall of the cleaning frame 4. The output shaft of the second motor 18 is fixedly connected to the cleaning roller 19 located inside the cleaning frame 4. The water spray box 12 and the spray box 16 are located on both sides of the cleaning roller 19, and multiple nozzles 20 are fixedly connected to the bottom. Adjustment grooves 21 are provided on all four sides of the empty groove in the middle of the clamping frame 5. The inner walls of the four adjustment grooves 21 are threaded with studs 22. One end of the four studs 22 passes through the empty groove in the middle of the clamping frame 5 and is rotatably engaged with an abutment block 23.

[0026] Specifically, the operator places the plastic sheet to be cleaned into the central slot of the clamping frame 5. By rotating the studs 22 in the four adjusting slots 21, the abutment blocks 23 at the ends of the studs 22 slowly approach and tightly abut against the edge of the sheet, ultimately securing the plastic sheet firmly in the center of the slot, ensuring no displacement during cleaning. The electric push rod 3, through the extension or retraction of the telescopic shaft, drives the cleaning frame 4 to rise and fall, ensuring that the cleaning roller 19 inside the cleaning frame 4 maintains close contact with the surface of the plastic sheet, guaranteeing that the cleaning force meets the requirements. After the first motor 8 starts, its output shaft drives the screw 9 to rotate. Due to the longitudinal plate of the moving frame 2, the screw 9 rotates... The moving frame 2 is threaded and slides along the groove 7 above the clamping frame 5 via the longitudinal plate. The moving frame 2 slides back and forth horizontally above the cleaning frame 1 along the groove 7 to achieve a comprehensive cleaning of the plastic board surface. During the movement of the moving frame 2, the water tank 10 sprays clean water through the nozzle 20 of the spray box 12 via the first pump body 11 to moisten the board surface; the foam tank 14 sprays cleaning foam through the nozzle 20 of the foam box 16 via the second pump body 15 to enhance the cleaning effect; at the same time, the second motor 18 drives the cleaning roller 19 to rotate continuously, and under the drive of the moving frame 2, it repeatedly wipes the moistened and foamed surface.

[0027] In this embodiment, the adjustment component 6 includes a strip plate 601 disposed on the outer side of the cleaning rack 1. A rod 602, which slides and engages with the cleaning rack 1, is fixedly connected to one side of the strip plate 601. Two fixing slots 612 are formed on one side of the clamping frame 5. The rod 602 passes through the slot in the middle of the cleaning rack 1 and engages with the fixing slots 612 on the clamping frame 5. A fixing rod 603, which rotates and engages with the cleaning rack 1, is fixedly connected to one side of the clamping frame 5. A connecting block 604 is disposed around the periphery of the fixing rod 603. A rod that slides and engages with the strip plate 601 is fixedly connected to one side of the connecting block 604. The sliding shaft 607 is connected to the connecting block 604. One side of the connecting block 604 has a through hole 608 that is sleeved around the fixed rod 603. The fixed rod 603 has a straight groove 609 and a spiral groove 610 around its periphery. The straight groove 609 and the spiral groove 610 are connected. The inner wall of the through hole 608 is fixedly connected to a sliding column 611 that slides and engages with the straight groove 609 and the spiral groove 610. One side of the strip plate 601 is fixedly connected to an abutment rod 605 that passes through one of the sliding grooves 7. A tension spring 606 is fixedly connected between one side of the strip plate 601 and the outer side of the cleaning rack 1.

[0028] Specifically, when the moving frame 2 cleans from the head end to the tail end of the plastic plate, it engages with the abutment rod 605 and pushes the strip plate 601 outward. The strip plate 601 drives the insertion rod 602 to disengage from the fixing groove 612, releasing the fixation of the clamping frame 5. At the same time, the strip plate 601 drives the sliding column 611 through the connecting block 604 to slide from the straight groove 609 of the fixing rod 603 into the spiral groove 610, driving the fixing rod 603 to rotate, thereby causing the clamping frame 5 and the plastic plate to complete a 180° flip. When the moving frame 2 returns, the tension spring 606 pulls the strip plate 601 back to its original position, and the insertion rod 602 re-inserts into the fixing groove 612 to fix the clamping frame 5, ensuring stability when cleaning the other side.

[0029] When using the device, firstly, the operator places the plastic sheet to be cleaned into the central slot of the clamping frame 5. By rotating the studs 22 in the four adjusting slots 21 respectively, the abutment block 23 at one end of the stud 22 slowly approaches and tightly abuts against the edge of the plastic sheet until the plastic sheet is firmly clamped in the center of the slot, ensuring that no displacement occurs during the cleaning process. The device is then started, and the telescopic shaft of the electric push rod 3 extends or retracts, causing the cleaning frame 4 to descend or rise, ensuring that the cleaning roller 19 inside the cleaning frame 4 maintains close contact with the surface of the plastic sheet to guarantee cleaning force. Then, the first motor 8 starts, and its output shaft drives the screw 9 to rotate. Because the screw 9 and the moving frame 2... One of the longitudinal plates is threaded, and the two longitudinal plates of the movable frame 2 are slidably engaged with the slide groove 7 above the clamping frame 5. The movable frame 2 slides laterally back and forth above the cleaning frame 1 along the slide groove 7. When the movable frame 2 cleans from the head end to the end of the plastic plate, it engages with the abutment rod 605 and continues to move, thereby pushing the strip plate 601 outward. At this time, the strip plate 601 drives the insertion rod 602 away from the fixing groove 612 and releases the fixing of the clamping frame 5. As the strip plate 601 moves outward, it drives the connecting block 604 outward, so that the sliding column 611 on the inner wall of the through hole 608 on the connecting block 604 slides into the spiral groove 609 of the fixing rod 603. The groove 610 drives the fixed rod 603 to rotate. The fixed rod 603 is fixedly connected to the clamping frame 5, realizing the flipping operation of the plastic plate on the clamping frame 5. When the moving frame 2 moves back, the strip plate 601 moves back through the force of the tension spring 606. The insertion rod 602 of the strip plate 601 is located in the fixed groove 612 to fix the clamping frame 5, so that the cleaning roller 19 at the bottom of the moving frame 2 keeps the cleaning of the other side of the flipped plastic plate stable. During the movement of the moving frame 2, the water storage tank 10 draws clean water through the first pump body 11 and delivers it to the water spray box 12 through the first connecting hose 13. Multiple nozzles 20 at the bottom of the water spray box 12 Clean water is evenly sprayed onto the surface of the plastic sheet to moisten the attached dust, debris, and other contaminants. As the moving frame 2 continues to move, the foam storage box 14 draws cleaning foam through the second pump body 15 and delivers it to the foam spray box 16 via the second connecting hose 17. The nozzle 20 of the foam spray box 16 sprays the cleaning foam onto the surface of the plastic sheet, enhancing the cleaning effect on stubborn stains such as oil. At the same time, the second motor 18 drives the cleaning roller 19 to rotate continuously, repeatedly wiping the surface of the plastic sheet that has been moistened and foamed under the action of the moving frame 2, forming a continuous cleaning process of "moistening - wiping - foaming - wiping again", and finally completing the comprehensive cleaning of the surface of the plastic sheet.
