[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a workpiece spraying production line, including: a conveying device, a drying processing box, and spray nozzles. The top of the conveying device is fixedly connected to the bottom of the drying processing box, and the top of the inner wall of the drying processing box is fixedly connected to the top of the spray nozzles.

[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] I. This utility model, by setting up components such as a motor, transmission gear, driven gear, and cleaning ring, enables the transmission gear to rotate through the motor. The meshing and transmission relationship between the transmission gear and the driven gear allows the cleaning ring to continuously clean the paint residue on the outer wall of the spray head through the rotation of the inner silicone brush.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] See attached document Figure 1-5 A workpiece spraying production line includes: a conveying device 1, a drying and processing box 2, and a spray nozzle 3. The top of the conveying device 1 is fixedly connected to the bottom of the drying and processing box 2, and the top of the inner wall of the drying and processing box 2 is fixedly connected to the top of the spray nozzle 3. A movable cleaning assembly 4 is provided on the top inside the drying and processing box 2. The movable cleaning assembly 4 includes a cleaning box 41. The top of the cleaning box 41 has several sets of connecting grooves 42. A cleaning ring 43 is movably connected inside the connecting grooves 42. A driven gear 44 is fixedly connected to the surface of the cleaning ring 43. A transmission gear 45 meshes with one side of the driven gear 44. A motor 46 is installed on the top of the wheel 45. The motor 46 is installed on the top of the inner wall of the cleaning box 41. The driven gears 44 mesh with each other. The number of connecting grooves 42 corresponds to the number of nozzles 3. The motor 46 drives the transmission gear 45 to rotate. The transmission gear 45 drives the driven gear 44 to rotate. The driven gear 44 then drives the cleaning ring 43 to rotate in the connecting groove 42. The rotation of the cleaning ring 43 can clean the paint residue on the outer wall of the nozzle 3 through the brush on its inner wall. The brush on the cleaning ring 43 is made of silicone bristles, which can be used effectively at high temperatures while avoiding damage to the nozzle 3.

[0031] The top of the drying and processing box 2 is equipped with a cleaning and collection assembly 5, which includes a blower 51. The suction end of the blower 51 is connected to a filter box 52, and the other end of the filter box 52 is connected to a connecting pipe 53. The other end of the connecting pipe 53 is connected to a collection box 54. The top of the collection box 54 is provided with several sets of collection slots 55, and the number of collection slots 55 corresponds to the number of connecting slots 42. During use, the suction force of the blower 51 causes the cleaned paint to fall into the collection slots 55 of the collection box 54 through the connecting slots 42. The paint in the collection box 54 is then sucked into the filter box 52 for filtration and collection through the connecting pipe 53. This achieves the cleaning of the nozzle 3 and the centralized recycling of paint residue, preventing the nozzle 3 from being blocked due to paint residue drying and ensuring the continuity of the spraying operation.

[0032] Two sets of movable gears 6 mesh on the other side of the driven gear 44. Movable columns 7 are fixedly connected inside the movable gears 6, and fixed rods 8 are threadedly connected inside the movable columns 7. The top of the fixed rods 8 is fixedly connected to the top of the drying and processing box 2. When the driven gear 44 rotates, it drives the two sets of movable gears 6 meshing on its other side to rotate. When the movable gears 6 rotate, they drive the internally fixed movable columns 7 to rotate synchronously. Since the movable columns 7 and the fixed rods 8 are threadedly connected, and the top of the fixed rods 8 is fixedly connected to the top of the drying and processing box 2, the movable columns 7 will move up and down along the axial direction of the fixed rods 8 when rotating, adjusting the overall height of the cleaning box 41 so that the nozzles 3 can be cleaned when cleaning is needed. During the movement of the cleaning box, driven by the motor 46... The cleaning ring 43 also rotates synchronously, directly cleaning the nozzle 3 upon contact with it until it reaches the bottom. Then, it reverses and resets via the motor 46. During this process, the cleaning ring 43 continues to clean the nozzle 3, forming a synchronous operation of descending cleaning and ascending cleaning. A sliding ring 9 is fixedly connected to the bottom of the movable column 7. Limiting grooves 10 are provided on both sides of the bottom surface inside the cleaning box 41. The surface of the sliding ring 9 is slidably connected to the inside of the limiting groove 10. The sliding ring 9 fixedly connected to the bottom of the movable column 7 can slide within the limiting grooves 10 provided on both sides of the bottom surface inside the cleaning box 41. The limiting grooves 10 limit the sliding ring 9, allowing the cleaning box to move up and down via the sliding ring 9 and the limiting grooves 10 when the movable column 7 rotates and rises.

[0033] Positioning grooves 11 are provided on both the top and bottom surfaces of the connecting groove 42. A support ring 12 is slidably connected inside the positioning groove 11. The support ring 12 is fixedly connected to the top and bottom of the cleaning ring 43. The positioning grooves 11 on the top and bottom surfaces of the connecting groove 42 can slide in cooperation with the support ring 12 fixedly connected to the top and bottom of the cleaning ring 43. The positioning grooves 11 provide a sliding track for the support ring 12, while the support ring 12 provides support and positioning for the cleaning ring 43. This ensures that the cleaning ring 43 maintains a stable axial position when rotating within the connecting groove 42, preventing tilting or displacement due to uneven force and ensuring smooth cleaning operation of the cleaning ring 43 on the nozzle 3. The cleaning box 41 is fixedly connected to a lifting rod 13 on its outer side. The top of the lifting rod 13 is fixedly connected to the top of the drying processing box 2. The lifting rod 13 fixedly connected to the top of the cleaning box 41 can limit the movement of the cleaning box 41 during lifting, allowing the cleaning box 41 to move stably. At the same time, it avoids the movable column 7 and the fixed rod 8 being directly stressed when the cleaning box 41 is subjected to external force, which could lead to damage to their threads. A time relay 14 is installed on the top of the drying processing box 2. The time relay 14 is electrically connected to a controller 15 through wires. The controller 15 is electrically connected to the motor 46 and the blower 51 through wires. Relay 14 can be preset with a cleaning cycle and cleaning duration. Time relay 14 is electrically connected to controller 15 via wires. Controller 15 is then electrically connected to motor 46 and blower 51 respectively. When the preset time is reached, time relay 14 sends a signal to controller 15, which then controls motor 46 and blower 51 to start cleaning. A filter plate 16 is slidably connected to the inner wall of collection box 54, and a transparent plate 17 is fixedly connected to one side of collection box 54. The filter plate 16 slidably connected to the inner wall of filter box 52 can filter paint residue sucked in by blower 51, trapping particulate impurities and preventing impurities from entering the blower 51 and causing damage. Filter box 52... The transparent plate 17, which is fixedly connected to one side, is made of transparent material, allowing for direct observation of the impurity accumulation on the filter plate 16. This facilitates operators in promptly determining whether the filter plate 16 needs to be removed for cleaning, ensuring filtration efficiency and normal operation. A collection box 18 is slidably connected to the bottom of the collection box 54. An anti-slip bar 19 is installed on one side of the collection box 18. The collection box 18, which is slidably connected to the bottom of the filter box 52, can be used to collect filtered paint residue or waste liquid. The anti-slip bar 19 installed on one side of the collection box 18 makes it easy for operators to grip and conveniently pull the collection box 18 out of the filter box 52 for cleaning or replacement, simplifying the maintenance process and improving the maintainability and practicality of the device.

[0034] Working principle: During use, the workpiece is fed into the drying chamber 2 via the conveyor 1, and the spray nozzle 3 sprays the workpiece. After spraying, the workpiece completes the drying process in the drying chamber 2. When the cleaning cycle preset by the time relay 14 is reached, the time relay 14 sends a signal to the controller 15, and the controller 15 starts the motor 46 and the blower 51.

[0035] Motor 46 drives transmission gear 45 to rotate, which in turn drives driven gear 44 to rotate. Due to the meshing of driven gears 44, multiple driven gears 44 rotate synchronously, thereby driving cleaning ring 43 to rotate in communicating groove 42. The silicone brush on the inner wall of cleaning ring 43 scrapes and cleans the paint residue on the outer wall of nozzle 3 as it rotates. At the same time, movable gear 6 meshing on the other side of driven gear 44 rotates with driven gear 44. Movable gear 6 drives the internal movable column 7 to rotate around fixed rod 8. Because movable column 7 is threaded to fixed rod 8, movable column 7 moves downward along the axis of fixed rod 8 when rotating. Through the cooperation of sliding ring 9 and limiting groove 10, it drives cleaning box 41 to descend as a whole, so that cleaning ring 43 gradually approaches nozzle 3. When movable column 7 moves to the bottom of fixed rod 8, motor 46 reverses, and movable column 7 drives cleaning box 41 to rise and reset along fixed rod 8. During this process, cleaning ring 43 continues to rotate, continuously cleaning nozzle 3.

[0036] While the cleaning ring 43 rotates to clean the nozzle 3, the blower 51 starts to generate suction. The cleaned paint residue falls into the collection tank 55 of the collection box 54 through the connecting groove 42. Under the action of airflow, it is sucked into the filter box 52 through the connecting pipe 53. The filter plate 16 in the filter box 52 traps paint particles and impurities, preventing them from entering the blower 51. The filtered airflow is discharged, while the paint residue falls into the collection box 18 at the bottom of the filter box 52 for centralized collection. The operator can observe the accumulation of impurities on the filter plate 16 through the transparent plate 17, and remove the filter plate 16 for cleaning when appropriate. The operator can also remove the collection box 18 through the anti-slip rod 19 to empty the residue, thus completing the recycling of cleaning waste and ensuring the cleanliness of the nozzle 3 and the continuous operation of the spraying production line.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
