Spray painting equipment mainly includes the following categories: air spraying equipment atomizes paint using compressed air, suitable for small to medium-scale operations, with low cost but efficiency limited by manual operation; high-pressure airless spraying equipment directly sprays paint using a high-pressure pump, capable of handling high-viscosity paints, and is highly efficient in large-area projects such as bridge waterproofing and ship corrosion protection; electrostatic spraying equipment uses an electric field to charge paint particles and adsorb them onto the workpiece, resulting in high coating uniformity, and is widely used in precision coating of automotive metal parts, appliance casings, etc.

[0003] The required coating thickness varies when spraying workpieces of different sizes. However, existing spraying equipment is difficult to quickly adjust the coating thickness when spraying workpieces of different sizes, and the spraying efficiency is low, making it difficult to ensure that the coating is evenly distributed on the workpiece surface.

[0021] 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.

[0022] Please see Figure 1-5The track-type automatic spray painting equipment of this embodiment includes a base 1. Several supports 2 are vertically fixedly connected to the top edge of the base 1. A track 3 is horizontally arranged between the tops of the supports 2. A transmission mechanism 4 is provided on the inner side of the track 3 to drive the carriers 5 on the outer side of the track 3 to move along the track 3. Several carriers 5 are evenly arranged on the outer side of the track 3. Each carrier 5 includes a fixed frame 501. A mounting base 502 is threadedly connected to the top of the fixed frame 501. A turntable 503 is rotatably connected to the top of the mounting base 502. A gear 504 is fixedly connected to the bottom of the turntable 503 around its axis. The side of the top of the base 1 away from the transmission mechanism 4 slides... A movable plate 9 is connected, and a connecting frame 11 is fixedly connected to the top of the movable plate 9. A rack 12 is horizontally fixedly connected to the side wall of the top of the connecting frame 11 facing the track 3. A gear 504 meshes with the rack 12. A mechanical arm 6 is provided on the inner side of the track 3 away from the transmission mechanism 4. A diversion pipe 7 is fixedly connected to the moving platform of the mechanical arm 6. Several nozzles 8 are fixedly connected to the side wall of the diversion pipe 7. A positioning pin 505 is fixedly connected to the top of the turntable 503. The positioning pin 505 is coaxially arranged with the turntable 503. An electric cylinder 10 is horizontally arranged on the side of the movable plate 9 facing the transmission mechanism 4. The piston rod of the electric cylinder 10 is fixedly connected to the side wall of the movable plate 9. During spraying, a carrier 5 matching the workpiece is selected using positioning pins 505 and gears 504, and then installed on the top of the fixed frame 501. The workpiece to be processed is then fixed to the top of the turntable 503 using positioning pins 505. The electric cylinder 10 drives the movable plate 9 to move towards the track 3, causing the connecting frame 11 and rack 12 to move accordingly until the rack 12 engages with gear 504. Then, the transmission mechanism 4 drives the carrier 5 and the workpiece to move along the track 3 towards the rack 12 and the spray nozzle 8. When the carrier 5 reaches the bottom where gear 504 contacts rack 12, gear 504 begins to rotate under the drive of rack 12, causing the turntable 503 and... The workpiece rotates accordingly; during the workpiece's movement, the spraying direction of the nozzles 8 on the side wall of the diversion pipe 7 is adjusted by the robotic arm 6, so that the spraying direction of the nozzles 8 is set opposite to the side wall of the workpiece. When the workpiece passes the spraying section below the nozzles 8 during its rotation, the outer side wall of the workpiece can be uniformly sprayed by the nozzles 8. By changing the diameter of the gear 504 and the position of the rack 12, the workpiece can rotate different numbers of revolutions during spraying, thereby adjusting the coating thickness on the workpiece surface. The carrier 5 and the workpiece are arranged relatively densely on the track 3, which allows for full utilization of the paint when the workpiece is sprayed in the spraying section, reducing paint waste and improving spraying efficiency.

[0023] The piston rod of the electric cylinder 10 is set perpendicular to the rack 12, and the rack 12 is set parallel to the flow divider 7.

[0024] The transmission mechanism 4 includes a motor 401, whose shaft is connected to a reducer 402. The output shaft of the reducer 402 is connected to a drive disk 403, the edge of which meshes with the inner side of the track 3. When the transmission mechanism 4 is in operation, the shaft of the motor 401 rotates. The reducer 402 reduces the speed of the motor 401 and increases the torque, which drives the drive disk 403 to rotate, causing the carrier 5 on the guide rail 3 to move.

[0025] Both gear 504 and rack 12 have chamfered edges on their teeth. By providing chamfers, the friction generated when the teeth of gear 504 and rack 12 come into contact can be reduced, thereby reducing the wear of gear 504 and rack 12, and preventing tooth collision.

[0026] Working principle: During spraying, a carrier 5 matching the workpiece is selected using positioning pins 505 and gears 504, and then installed on the top of the fixed frame 501. The workpiece to be processed is then fixed to the top of the turntable 503 using positioning pins 505. The electric cylinder 10 drives the movable plate 9 to move towards the track 3, causing the connecting frame 11 and rack 12 to move accordingly until the rack 12 engages with gear 504. Then, the transmission mechanism 4 drives the carrier 5 and the workpiece to move along the track 3 towards the rack 12 and the spray head 8. When the transmission mechanism 4 operates, the shaft of the motor 401 rotates. The speed of the motor 401 is reduced and the torque increased by the reducer 402, driving the drive disc 403 to rotate, causing the carrier 5 on the guide rail 3 to move. When the carrier 5 moves to the bottom gear... When gear 504 contacts rack 12, gear 504 begins to rotate under the drive of rack 12, causing turntable 503 and workpiece to rotate accordingly. During the movement of the workpiece, the spraying direction of nozzle 8 on the side wall of the diversion pipe 7 is adjusted by robotic arm 6, so that the spraying direction of nozzle 8 is set opposite to the side wall of the workpiece. When the workpiece passes the spraying section below nozzle 8 during rotation, the outer side wall of the workpiece can be uniformly sprayed by nozzle 8. By changing the diameter of gear 504 and the position of rack 12, the workpiece can rotate different numbers of revolutions during spraying, thereby adjusting the coating thickness on the workpiece surface. The carrier 5 and workpiece are arranged relatively densely on track 3, which allows for full utilization of paint when the workpiece is sprayed in the spraying section, reducing paint waste and improving spraying efficiency.

[0027] 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.
