[0023] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0024] This utility model discloses a coating roller cleaning and maintenance device.

Two upright plates 2 are symmetrically installed on the top of the support platform 1. An arc-shaped groove 21 is formed on the upright plate 2, and the coating roller 11 is rotatably installed on the arc-shaped groove 21. A rectangular cavity structure is set in the middle of the upright plate 2, and the sliding mechanism 3 is slidably installed inside the rectangular cavity structure.

The slider 31 is slidably installed inside the rectangular cavity structure, and the rotating shaft 32 is installed between the two sliders 31. Gears 33 are installed at both ends of the rotating shaft 32, and the rack 34 is installed on the upright plate 2. The gears 33 and rack 34 mesh. The connection is as follows: a connecting plate 22 is provided at the top of the upright plate 2; a hydraulic cylinder 4 is installed on the connecting plate 22; the piston rod 41 of the hydraulic cylinder 4 passes through the connecting plate 22 and is connected to the slider 31; a cleaning roller 5 is rotatably installed on the slider 31; a motor 6 is installed at the end of the slider 31; the cleaning roller 5 is connected to the output end of the motor 6; a V-groove 51 is provided on the cleaning roller 5; a cleaning blanket 7 is wound around the outside of the cleaning roller 5 and extends into the V-groove 51; a V-shaped pressure block 8 for pressing the cleaning blanket 7 is installed inside the V-groove 51; a threaded hole is provided on the cleaning roller 5; a countersunk screw hole is provided on the V-shaped pressure block 8; a countersunk bolt 9 is fitted into the countersunk screw hole and the threaded hole; the V-shaped pressure block 8 is embedded in the V-groove 51 and fixed in the threaded hole of the cleaning roller 5 by the countersunk bolt 9; a controller 10 is installed on the upright plate 2; and the hydraulic cylinder 4, the motor 6 and the controller 10 are electrically connected.

[0025] The cleaning roller 5 is provided in two parts, and the cleaning roller 5 is connected to each other by a belt drive mechanism; this reduces the number of motors 6 and lowers operating costs.

[0026] The cleaning blanket 7 has a two-layer composite structure, including a base fabric layer and a microporous adsorption layer. The microporous adsorption layer is impregnated with an organic solvent-based cleaning agent. The microporous adsorption layer releases the organic solvent-based cleaning agent to dissolve surface dirt, while the base fabric layer provides a physical wiping effect.

[0027] Multiple countersunk bolts 9 are arranged at intervals along the axial direction of the cleaning roller 5; by locking multiple countersunk bolts 9 at intervals along the axial direction, the cleaning blanket 7 is ensured to be evenly fixed.

[0028] The cleaning roller 5 is the same length as or slightly shorter than the coating roller 11, ensuring that the coating roller 11 is thoroughly cleaned.

[0029] The contact surface between the V-shaped pressure block 8 and the V-shaped groove 51 is provided with anti-slip texture 81; the V-shaped pressure block 8 is embedded into the V-shaped groove 51, the anti-slip texture 81 is used to increase the friction, and multiple countersunk bolts 9 are locked along the axial interval to ensure that the cleaning blanket 7 is evenly fixed.

[0030] The hydraulic cylinder 4 is fixedly connected to the connecting plate 22 via a flange, and a rubber shock-absorbing pad 42 is provided between the flange and the connecting plate 22. The flange connection design facilitates the inspection and maintenance of the hydraulic cylinder 4, and the rubber shock-absorbing pad 42 ensures smooth movement.

[0031] The bottom of the slider 31 is equipped with a pressure sensor 12, which is electrically connected to the controller 10; this enables automated control, reduces labor intensity, and improves work efficiency.

[0032] The piston rod 41 of the hydraulic cylinder 4 is plated with a hard chrome layer; the hard chrome plating has high hardness, good wear resistance and corrosion resistance, which can significantly extend the service life of the piston rod.

[0033] The arc-shaped groove 31 is embedded with a ball bearing, and the journals at both ends of the coating roller 11 form a detachable rotatable fit with the ball bearing; the journals at both ends of the coating roller 11 are embedded in the arc-shaped groove 21 of the vertical plate 2 to ensure that it fits tightly with the bearing in the arc-shaped groove 21, and avoids shaking during the cleaning process. Since the ball bearing is embedded in the arc-shaped groove 31, the coating roller 11 can rotate easily and form a detachable connection with the vertical plate 2, which facilitates loading and unloading operations.

[0034] Work process:

[0035] The journals at both ends of the coating roller 11 are embedded into the arc-shaped grooves 21 of the vertical plate 2, and rotatable installation is achieved by ball bearings. The photovoltaic glass is conveyed to the support platform by the conveying equipment, and the coating operation is performed at the bottom of the coating roller. The controller 10 detects the electrical connection status of the hydraulic cylinder 4, the motor 6 and the pressure sensor 12. The controller 10 sets the stroke parameters of the hydraulic cylinder 4 and the speed range of the motor 6, and presets the cleaning pressure threshold according to the degree of dirt on the coating roller 11. Two layers of composite structure blankets are laid flat on the surface of the cleaning roller 5, and after the end is inserted into the V-groove 51, the V-shaped pressure roller with anti-slip texture 81 is used. Block 8 is pressed down and fixed by countersunk bolts 9 arranged at intervals. The controller 10 is activated, and the hydraulic cylinder 4 pushes the piston rod 41 downwards, causing the sliding mechanism 3 to descend as a whole. Gear 33 meshes with rack 34, ensuring that the two sliders 31 move synchronously and vertically. Simultaneously, pressure sensor 12 monitors the contact pressure between the cleaning roller 5 and the coating roller 11 in real time and feeds the data back to the controller 10. The controller 10 adjusts the cylinder pressure. When the pressure reaches a preset threshold, the controller 10 stops the hydraulic cylinder 4, ensuring close contact between the cleaning roller 5 and the coating roller 11. The contact pressure is mitigated by the rubber shock-absorbing pad 42. To reduce vibration interference, motor 6 is started, driving cleaning roller 5 to rotate. A belt drive mechanism maintains synchronous operation of both rollers. Cleaning roller 5 drives cleaning blanket 7 to rotate at high speed. The two layers of cleaning blanket 7 work together to achieve cleaning: the microporous adsorption layer releases organic solvent-based cleaning agents to dissolve surface dirt, while the base fabric layer provides physical wiping. Coating roller 11 rotates synchronously under the drive device, achieving comprehensive circumferential cleaning. During the cleaning process, pressure sensor 12 continuously monitors the force on slider 31. If pressure fluctuations occur due to uneven dirt thickness, controller 10 automatically adjusts the stroke of hydraulic cylinder 4. Maintain constant contact pressure to prevent the cleaning roller 5 from being overly squeezed or detached from the coating roller 11. After cleaning, the controller 10 controls the hydraulic cylinder 4 to retract the piston rod 41, and the sliding mechanism 3 drives the cleaning roller 5 away from the coating roller 11 until they are completely separated. The motor 6 stops running, the cleaning roller 5 stops, the countersunk bolt 9 is loosened, the V-shaped pressure block 8 is removed, the blanket is replaced or cleaned, and the rubber shock-absorbing pad 42 at the flange connection of the hydraulic cylinder 4 is checked for aging and the hard chrome layer of the piston rod 41 is checked for wear. The lubricating grease of the gear 33 and the rack 34 is cleaned and new grease is added to ensure smooth operation of the sliding mechanism 3.
