[0002] With the rapid development of my country's construction industry, the demand for wall panels, wall tiles and other wall materials is increasing. Modern building wall materials require energy saving and environmental protection to ensure the sustainable development of the national economy. The use of solid waste such as slag, fly ash, steel slag, coal gangue, tailings, ceramsite, rice husk, straw, etc. to produce various lightweight and environmentally friendly partition boards has become a development direction. The use of mechanical extrusion methods to produce lightweight partition boards is through an extrusion and pushing mechanism to squeeze and vibrate the material, and move forward through the reverse thrust force, in strips. Uninterrupted production, the product has the characteristics of high density, strong impact resistance, fire resistance, earthquake resistance, sound insulation and heat insulation.

[0003] Due to the rapid development of modular houses composed of new wall panels, the existing new wall panels need to be painted during the processing to improve the service life and aesthetics of the new wall panels. Therefore, in order to make the paint surface of the wall panels adhere more evenly after painting, the surface of the wall panels needs to be cleaned before painting.

The bottom of the moving block 4.3 is fixedly connected to the top of the cylinder 5.

[0023] In this embodiment, when the wall panel moves to the bottom of the cleaning assembly 6, the cleaning assembly 6 is started, and the motor 4.1 is started at the same time, the threaded rod 4.2 rotates, driving the moving block 4.3 to move, and the mounting plate 6.4 can be controlled to move left and right, thereby driving the cleaning brush 6.5 to clean the surface of the wall panel.

[0024] like Figure 4 , Figure 6 As shown, the cleaning assembly 6 includes a water tank 6.1, a discharge pipe 6.2, a bellows 6.3, a mounting plate 6.4, a cleaning brush 6.5, and a spray port 6.6.

The bellows 6.3 can be bent, stretched and adjusted as the mounting plate 6.4 and the cylinder 5 adjust the position of the cleaning brush 6.5, so as to facilitate the cleaning of the entire wall panel. One end of the bellows 6.3 is fixedly connected to a discharge pipe 6.2, which is fixed to the side wall and top of the mounting frame 23 by a plurality of buckles. The discharge pipe 6.2 penetrates into the inner cavity of the water tank 6.1 and is connected to the liquid pump.

[0025] In this embodiment, when the wall panel is cleaned before painting, the wall panel is first placed on the placement rack 15 of the conveyor belt of the conveyor device 2, and the conveyor device 2 is started. The conveyor belt drives the wall panel to move. When the wall panel moves to the bottom of the cleaning component 6, the cylinder 5 is started to push the mounting plate 6.4 downward. When the cleaning brush 6.5 contacts the wall panel, the liquid pump in the water tank 6.1 is started, so that the cleaning liquid passes through the discharge pipe 6.2 to the bellows 6.3, and finally sprays out from the spray port 6.6 to the surface of the wall panel. At the same time, the moving component 4 is started to control the mounting plate 6.4 to move left and right, thereby driving the cleaning brush 6.5 to clean the surface of the wall panel.

[0026] like Figure 1-2 As shown, the top of the second mounting frame 3 is fixedly connected to the third mounting frame 11, and the two sides of the second mounting frame 3 are symmetrically provided with non-through receiving grooves 9, and the two sides of the inner cavity of the receiving groove 9 are symmetrically provided with sliding grooves 10.

[0027] In this embodiment, the length of the accommodating groove 9 is longer than the length of the connecting plate 7.5, so that the connecting plate 7.5 can be placed in the inner cavity of the accommodating groove 9 without turning over the wall panel.

[0028] like Figure 1-2As shown, the flip assembly 7 includes a motor 2 7.1, a gear 7.2, a rack plate 7.3, a connecting block 7.4, a connecting plate 7.5, a slider 7.6, an electric telescopic rod 7.7, a vertical plate 7.8, a motor 3 7.9, a clamping plate 7.10, and a rubber anti-skid pad 7.11. The motor 2 7.1 is fixedly connected to the top of the mounting frame 3 11, and the output end of the motor 2 7.1 passes through the mounting frame 3 11 and is fixedly connected with a gear 7.2. The gear 7.2 is rotatably connected to the top of the mounting frame 2 3 through a bearing. Rack plates 7.3 are symmetrically arranged on both sides of the gear 7.2. The gear 7.2 is meshed and connected with the rack plate 7.3. The rack plate 7.3 is slidably connected to the top of the mounting frame 2 3. The rack plate 7.7 is fixedly connected to the top of the mounting frame 2 3. .3 A connecting block 7.4 is fixedly connected to one end of the bottom, a connecting plate 7.5 is fixedly connected to the bottom of the connecting block 7.4, an electric telescopic rod 7.7 is fixedly connected to the bottom of the connecting plate 7.5, a vertical plate 7.8 is fixedly connected to the bottom of the electric telescopic rod 7.7, and a clamping plate 7.10 is symmetrically connected to the opposite sides of the two vertical plates 7.8 through bearings. A rubber anti-skid pad 7.11 is fixedly connected to one side of the clamping plate 7.10 to increase friction when clamping the wall panel, thereby firmly clamping the wall panel for easy flipping, and a motor three 7.9 is fixedly connected to one side of one vertical plate 7.8, and the output end of the motor three 7.9 passes through the vertical plate 7.8 and is fixedly connected to the clamping plate 7.10.

[0029] Slide blocks 7.6 are symmetrically fixedly connected on both sides of the connecting plate 7.5. The connecting plate 7.5 is slidably connected to the inner cavity of the accommodating groove 9, and the slide blocks 7.6 are slidably connected to the inner cavity of the slide groove 10. When the connecting plate 7.5 moves in the inner cavity of the accommodating groove 9, the slide blocks 7.6 move in the inner cavity of the slide groove 10, thereby playing a good limiting and guiding role for the connecting plate 7.5.

[0030] In this embodiment, when one side of the wall panel is cleaned and the other side needs to be cleaned, the motor 2 7.1 is started to drive the gear 7.2 to rotate, and the rack plate 7.3 is driven to move outward through the meshing relationship, thereby driving the connecting plate 7.5 to slide out of the inner cavity of the accommodating groove 9 and move outward. At this time, the electric telescopic rod 7.7, the vertical plate 7.8, the clamping plate 7.10 and the like move with the connecting plate 7.5. When the two connecting plates 7.5 are extended to a length exceeding the length of the wall panel, the electric telescopic rod 7.7 is started to extend, and the clamping plate 7.10 is lowered to both sides of the wall panel, the electric telescopic rod 7.7 is stopped, and the motor 2 7.1 is started again to drive the gear 7.2 to rotate in the opposite direction, so that the two clamping plates 7.10 can move the wall panel from both sides. After the wall panel is fixed, the electric telescopic rod 7.7 is shortened and started to raise the wall panel to a certain height, and the motor three 7.9 is started to drive the clamping plate 7.10 and the wall panel therein to rotate, so that the wall panel can be turned over, and the electric telescopic rod 7.7 is extended again to place the wall panel on the placement rack 15 of the conveyor belt of the conveyor device, and the motor two 7.1 is started to release the clamping plate 7.10 from both sides of the wall panel, and then the entire turning assembly 7 is retracted, and the moving assembly 4 and the cleaning assembly 6 are started to clean the other side of the wall panel. The whole process has a high degree of automation, which is convenient for turning over the wall panel and can continuously clean the two sides of the wall panel without manual turning over, thereby reducing the labor intensity of manual operation and effectively improving the cleaning efficiency of the wall panel.

[0031] like Figure 5 , Figure 7-8 As shown, the wiper assembly 8 includes an L-shaped plate 8.1, a support 8.2, a scraper 8.3, a spring 8.4, a fixing column 8.5, a second waste liquid collection box 8.6, and a second through hole 8.7. The second waste liquid collection box 8.6 is arranged on one side of the mounting frame 1 and is located on the side where the conveying device 2 outputs the items. The top side of the second waste liquid collection box 8.6 is symmetrically fixedly connected with a fixing column 8.5. Two L-shaped plates 8.1 are symmetrically fixedly connected to the side walls of the two fixing columns 8.5. The distance between the two L-shaped plates 8.1 is such that one end of the two scrapers 8.3 just contacts the side wall of the wall panel, and the L-shaped supports of the two L-shaped plates 8.1 are A gap is left between the plates for the wall panels to pass through. The bottom and one side of the top of the inner cavity of the two L-shaped plates 8.1 are symmetrically fixedly connected with supports 8.2. The inner cavity of the support 8.2 is rotatably connected with a scraper 8.3. One side of the scraper 8.3 is fixedly connected with a plurality of springs 8.4. The other end of the spring 8.4 is fixedly connected to the side wall of the inner cavity of the L-shaped plate 8.1. A buffer block is provided at one end of the scraper 8.3 close to the spring 8.4. The buffer block can prevent the scraper 8.3 from causing wear to the wall panels. The bottom of the inner cavity of the bottom L-shaped plate 8.1 is evenly opened with a plurality of through holes 8.7, and the edge of the bottom L-shaped plate 8.1 is provided with a water retaining plate.

[0032] In this embodiment, when both sides of the wall panel are cleaned, the wall panel moves to the side of the wiper assembly 8 along with the conveyor belt of the conveying device 2. At this time, the wall panel enters between the two L-shaped plates 8.1, and one end of the two scrapers 8.3 just contacts the wall panel. When the wall panel passes, the spring 8.4 can exert a force on the scraper 8.3, which is convenient for scraping off the residual cleaning liquid on both sides of the wall panel, and flowing into the waste liquid collection box 8.6 along the through hole 8.7 for recycling, effectively reducing the waste of resources.

[0033] like Figure 1-2 As shown, a plurality of through holes 14 are evenly opened on the conveyor belt of the conveyor device 2, a plurality of placement racks 15 are evenly fixedly connected to the conveyor belt of the conveyor device 2, and the placement racks 15 are spaced apart from the through holes 14, a through slot 12 is opened at the bottom of the mounting rack 1, and the slot 12 and the waste liquid collection box 13 are on the same vertical line, and the size of the slot 12 is smaller than the opening size of the waste liquid collection box 13.

[0034] In this embodiment, during the cleaning process of the wall panel, the wall panel is placed on the top of the placement rack 15. On the one hand, it is convenient for the flipping component 7 to clamp the wall panel when the wall panel is turned over. On the other hand, it is convenient for excess cleaning liquid on the wall panel to flow down. At this time, the excess cleaning liquid passes through the through hole 14 on the conveyor belt of the conveying device 2, and then passes through the through groove 12 to be introduced into the waste liquid collection box 13 for recycling, which effectively reduces the waste of resources.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0036] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
