Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-3 As shown, the board back coating machine includes a worktable 100, a dust cover 200, a coating component 300, and a dust collection component 400. The worktable 100 includes a tabletop 101 and support legs 102. The support legs 102 are fixed to the lower end of the tabletop 101. The dust cover 200 is provided on the tabletop 101. The coating component 300 and the dust collection component 400 are provided inside the dust cover 200. In use, the board is placed on the worktable 100, and the board passes through the dust collection component 400 and the coating component 300 in sequence. The dust collection component 400 first cleans the coating surface of the board, and then the coating component 300 applies the coating to the board.

[0025] In one embodiment, such as Figure 3 As shown, the top surface of the workbench 100 is provided with an auxiliary roller 103, which is rotatably connected to the workbench 101. During use, the lower end of the board contacts the auxiliary roller 103, and the auxiliary roller 103 enables the board to move more smoothly.

[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, the dust cover 200 includes a cover body 201. One end of the cover body 201 is provided with an inlet 202, and the other end of the cover body 201 opposite to the inlet 202 is provided with an outlet 203. The top of the cover body 201 is provided with an observation window 204, and the observation window 204 is provided with a glass plate. In use, the material enters the cover body 201 through the inlet 202, passes through the dust suction component 400 and the painting component 300 in sequence, and then leaves through the outlet 203.

[0027] In one embodiment, such as Figure 3As shown, the painting assembly 300 includes a painting roller, a paint supply assembly, and a drive assembly. Three painting rollers are arranged linearly inside the dust cover 200. The two ends of the painting rollers are rotatably connected to the cover body 201. Each painting roller is equipped with a paint supply assembly. The drive assembly is located at the end of the painting roller and is located outside the dust cover 200. In use, the paint roller is driven to rotate by the drive assembly to paint the board. Paint is added to the painting roller by the paint supply assembly.

[0028] In one embodiment, such as Figure 3 As shown, the coating roller includes an outer ring 301, an inner shaft 302, and spring pieces 303. The inner shaft 302 is rotatably connected to the cover 201. The outer ring 301 is sleeved on the outside of the inner shaft 302. The spring pieces 303 are evenly distributed between the outer ring 301 and the inner shaft 302. In use, the outer ring 301 can adjust its position automatically when it receives external force through the spring pieces 303, so as to achieve the purpose of coating plates of different thicknesses.

[0029] In one embodiment, such as Figure 2 and Figure 3 As shown, the paint supply assembly includes a dispensing box 304 and a sponge block 306. Both ends of the dispensing box 304 are fixed to the inner wall of the cover 201. The sponge block 306 is located at the lower end of the dispensing box 304. A leakage hole 305 is provided on the contact surface between the dispensing box 304 and the sponge block 306. The lower end of the sponge block 306 is in frictional contact with the paint roller. One end of the dispensing box 304 is connected to a storage box 307. The storage box 307 is fixed to the outside of the cover 201. In use, the paint enters the dispensing box 304 from the storage box 307, and then enters the sponge block 306 from the dispensing box 304 through the leakage hole 305. The sponge block 306 then evenly spreads the paint onto the paint roller.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the drive assembly includes a motor 308 and a belt 310. The motor 308 is fixed on the outside of the cover 201. The output end of the motor 308 is connected to one end of the paint roller. Two adjacent paint rollers are connected by a belt 310. The belt 310 is sleeved and fixed on the pulley 309 at the end of the paint roller. In use, the motor 308 drives one paint roller to rotate, and then the belt 310 between the paint rollers drives the other two paint rollers to rotate.

[0031] In one embodiment, such as Figure 4As shown, the dust collection assembly 400 includes a ventilation box 401, a dust collection box 403, a filter plate 404, and a negative pressure fan 405. The ventilation box 401 is fixed inside the cover 201. A dust collection port 402 is provided at the lower end of the ventilation box 401. One end of the ventilation box 401 passes through the side wall of the cover 201 and communicates with the dust collection box 403. The dust collection box 403 is fixed outside the cover 201. The negative pressure fan 405 is located at one end of the dust collection box 403. A filter plate 404 is provided at the air inlet end of the negative pressure fan 405. In use, the negative pressure fan 405 draws air from the ventilation box 401, causing suction at the dust collection port 402 to achieve the dust collection effect.

[0032] The above embodiment discloses a back-coating machine for sheet metal. In use, the motor 308 is turned on to drive the coating roller to rotate, pushing the sheet metal into the cover 201 from the inlet 202. The sheet metal passes through the dust suction port 402, and the dust on the sheet metal is sucked into the dust collection box 403 by the negative pressure fan 405. The sheet metal passes through the dust suction port 402 to reach the coating roller. The rotation of the coating roller drives the sheet metal forward, and at the same time, the sheet metal is coated. Finally, the sheet metal leaves from the outlet 203.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
