[0002] A spray painting production line is a production line that sprays colors and coatings onto the surface of products. In order to reduce or minimize the impact of dust on spray painting and meet the spray painting production requirements of workpieces, the workpieces need to be dusted before spray painting to ensure that there is no dust adhering to the workpiece surface.

[0003] As disclosed in announcement number CN222268117U, a dust removal pretreatment device includes a collection box and a connecting pipe for industrial equipment dust removal, as well as a cleaning component. The collection box has an air inlet and an exhaust fan connected to its inner cavity on its outer side. The cleaning component includes a mounting sleeve and multiple sets of connected rotating shafts. The mounting sleeve is threaded to the air inlet. Multiple sets of spring-loaded telescopic pins are evenly arranged on the outer side of the rotating shafts, and cleaning blocks are fixedly connected to the outer side of each spring-loaded telescopic pin. Two sets of symmetrical bent rods are fixedly connected to the outer side of the air inlet, and limit pins are movably inserted through the outer side of each bent rod. Two sets of limit holes connected to the limit pins are provided on the outer side of the connecting pipe.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-7 .

[0032] To address the problems of inconvenience in uniformly and thoroughly removing dust from workpieces, poor dust removal effect, and environmental pollution caused by the removed dust, as well as the inconvenience in adsorbing and cleaning dust in existing technologies, this solution provides a workpiece dust removal pretreatment device for a painting production line. The device includes a production line conveyor 1, a conveyor plate 2, and a dust removal pretreatment chamber 10. A support frame 5 is fixedly connected to the upper end of the conveyor plate 2, and a worktable 7 is rotatably connected to the upper end of the support frame 5. Painting workpieces are placed on the worktable 7, which drives the painting workpieces to rotate relative to each other on the upper end of the conveyor plate 2. Soft rubber curtains 11 are installed on both the left and right sides of the dust removal pretreatment chamber 10, and air nozzles 13 are evenly spaced at the rear end of the inner side of the dust removal pretreatment chamber 10. A suction hood 15 is fixedly connected to the upper end of the dust removal pretreatment chamber 10, and a dustproof net 16 is inserted into the suction hood 15.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the painted workpiece is placed on the workbench 7. The production line conveyor 1 is equipped with a screw conveyor assembly, and the movable connecting block 3 is threadedly connected to the screw. The drive device drives the screw to rotate in the production line conveyor 1. The screw drives the movable connecting block 3 to move in the production line conveyor 1, thereby causing the conveyor plate 2 to slide between the linear guide rail 4, so that the conveyor plate 2 carries the workpiece. When the workpiece enters the dust removal pretreatment room 10 through the soft rubber curtain 11 on the left, the reduction motor 6 installed in the middle of the support frame 5 is started. The reduction motor 6 drives the workbench 7 to rotate at the upper end of the support frame 5, and the workbench 7 drives the ball bearing 8 to roll in the annular groove 9, thereby improving the stability of the workbench 7 rotating at the upper end of the support frame 5.

[0034] The worktable 7 drives the workpiece to rotate slowly at the upper end of the support frame 5, combined with... Figure 6 and Figure 7As shown, an air blowing pipe 12 is provided at the inner rear end of the dust removal pretreatment chamber 10. Air nozzles 13 are provided at equal intervals on the front and upper ends of the air blowing pipe 12. The air blowing pipe 12 is connected to an external air pump. When the air pump is turned on, air is blown onto the workpiece through the air blowing pipe 12 and the air nozzles 13, thereby blowing off the dust on the outer surface of the workpiece. As the workpiece rotates in the dust removal pretreatment chamber 10, the dust in all positions of the workpiece can be blown off fully and evenly, achieving a better dust removal effect. Transparent observation windows are provided at both the front and rear ends of the dust removal pretreatment chamber 10, allowing observation of the dust removal operation in the dust removal pretreatment chamber 10.

[0035] After the dust is blown away, the suction device 14 installed at the upper left of the dust removal pretreatment chamber 10 is activated. The suction end of the suction device 14 is connected to the suction hood 15, which can absorb and clean the dust in the dust removal pretreatment chamber 10. The entire dust removal operation is carried out in the dust removal pretreatment chamber 10. Soft rubber curtains 11 are installed on both the left and right sides of the dust removal pretreatment chamber 10 to prevent dust from spreading into the external environment and causing pollution. The suction hood 15 absorbs and cleans the dust. The dustproof net 16 is inserted into the middle of the suction hood 15 to prevent dust from entering the suction device 14. After the workpiece is dusted, the screw drive assembly continues to drive the conveyor plate 2 to move to the right, moving the workpiece to the right for the next painting operation. After use, the bolts between the suction hood 15 and the dustproof net 16 can be removed, and the dustproof net 16 can be disassembled and cleaned.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
