[0032] The reciprocating swing cleaning brush mechanism 6 includes a multi-path fixing mechanism 11, which is arranged inside the fixed support plate mechanism 8. The multi-path fixing mechanism 11 includes a fixed support seat 31, a vertical cylinder 32, a threaded pushing mechanism 33, and an extrusion mechanism 34. The fixed support seat 31 is arranged inside the rectangular ring plate 17. The vertical cylinder 32 is fixedly connected to the fixed support seat 31 and passes through the fixed support seat 31. It is arranged at the upper end of the cleaning brush head 27. The threaded pushing mechanism 33 is threadedly sleeved on the surface of the vertical cylinder 32. The threaded pushing mechanism 33 includes a threaded sleeve 35 and a pushing cylinder 36. The threaded sleeve 35 is threadedly sleeved on the surface of the vertical cylinder 32. The pushing cylinder 36 is sleeved on the vertical cylinder 32 and fixedly connected to the upper end of the threaded sleeve 35. The vertical cross-section of the pushing cylinder 36 is an isosceles trapezoidal structure. The extrusion mechanism 34 is provided with four groups of array-type connections to the vertical cylinder 32. The extrusion mechanism 34 includes The support seat plate 37, the rotating rod 38, and the L-shaped plate 39 are provided with a through groove 40 on the vertical tube 32. The support seat plate 37 is arranged on one side of the through groove 40 and is fixedly connected to the vertical tube 32. The L-shaped plate 39 includes a pushing part and an extruding part. The extruding part and the pushing part are integrally formed. The pushing part is rotatably connected to the support seat plate 37 through the rotating rod 38. The pushing part is attached to the outer surface of the pushing tube 36, and the end of the extruding part away from the pushing part extends into the through groove 40. The rod body of the paintbrush is placed in the vertical tube 32, and the threaded sleeve 35 is rotated to drive the pushing tube 36 to move upward. The vertical cross-section of the pushing tube 36 is an isosceles trapezoidal structure. When the pushing tube 36 moves upward, the pushing part of the L-shaped plate 39 is squeezed to make the L-shaped plate 39 rotate. The extruding part of the L-shaped plate 39 passes through the through groove 40 to squeeze the rod body of the paintbrush to fix the paintbrush. In the above manner, paintbrush rods of various diameters can be fixed.

[0033] The paintbrush is fixed by the multi-path fixing mechanism 11, which is driven to move in the fixed support plate mechanism 8 with the assistance of the displacement driving mechanism 7, and the multi-path fixing mechanism 11 is swung with the assistance of the reciprocating swing auxiliary mechanism 9, and the cleaning brush mechanism 10 is rotated in the same direction as the multi-path fixing mechanism 11 with the assistance of the variable speed belt mechanism 12 to clean the brush.

[0034] A multi-path fixing mechanism 11 is provided on the sealing plate 2, and a vertical cylinder 32 inside the multi-path fixing mechanism 11 is fixed through the sealing plate 2 and extends into the drying area 4.

[0035] Principle of the present invention: When in use, a cleaning liquid is put into the cleaning area 3, the sealing plate 2 is covered, the rod body of the paintbrush is put into the vertical cylinder 32, the threaded sleeve 35 is rotated, and the pushing cylinder 36 is driven to move upward. The vertical section of the pushing cylinder 36 is an isosceles trapezoidal structure. When the pushing cylinder 36 moves upward, the pushing part of the L-shaped plate 39 is squeezed, so that the L-shaped plate 39 rotates. The squeezing part of the L-shaped plate 39 passes through the through groove 40 and squeezes the rod body of the paintbrush to fix the paintbrush. In this way, the paintbrush rod bodies of various diameters can be fixed; After the brush is fixed, the driving motor 13 is started, driving the threaded rod 14 to rotate, and driving another threaded rod 14 to rotate through the pulley mechanism 16, thereby driving the lead screw sleeve 19 to move, and then driving the L-shaped plate 18 and the rectangular ring plate 17 to move, and then driving the multi-path fixing mechanism 11 to move, and finally driving the brush to move, so as to clean the brush; When the rectangular ring plate 17 moves, it drives the Z-shaped shaft 22 to move, and the rotating wheel 23 moves in the corrugated groove 24. Under the action of the corrugated groove 24, the Z-shaped shaft 22 swings repeatedly, thereby driving the swing of the multi-path fixing mechanism 11, and then driving the swing of the brush, thereby increasing the cleaning effect; When the Z-shaped shaft 22 rotates, the speed-changing belt mechanism 12 drives the supporting crossbar 26 to rotate, thereby driving the cleaning brush head 27 to rotate. The cleaning combing head 27 combs and stretches the brush of the brush to clean the brush head, thereby ensuring the cleaning effect. After cleaning, the paintbrush is removed and placed on the multi-path fixing mechanism 11 at the upper end of the drying area 4, and fixed by the multi-path fixing mechanism 11. The air inside the drying area 4 is heated by the heating drying wire 41, thereby drying the brush tip.

Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the authorization requirements.
