[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] This application discloses an integrated powder coating and painting device for sheet metal processing. (Refer to...) Figure 1-3 A powder coating and painting integrated device for sheet metal processing includes a frame 1. The frame 1 is placed on a flat and stable working ground. The frame 1 is precisely leveled using a level to ensure that it is in a horizontal state, so as to ensure the stability of subsequent equipment installation and operation. The frame 1 is firmly fixed to the ground using expansion bolts.

[0024] On the outer wall of the frame 1, the conveying mechanism 2 is installed strictly in accordance with the design drawings. The conveying mechanism 2 uses multiple sets of parallel conveying rollers. The spacing between adjacent conveying rollers is reasonably set according to the size of common plates to ensure that the plates can move smoothly and steadily on the conveying rollers. Each conveying roller is installed on the frame 1 through a bearing seat to ensure that it can rotate flexibly.

[0025] The drive motor (not shown in the figure) of the conveyor mechanism 2 is installed. The drive motor is connected to the conveyor roller through a belt or chain transmission component to provide power to the conveyor roller. This is existing technology and will not be described in detail. During the installation process, the tension of the transmission component is adjusted to ensure that it is in a suitable state and to avoid slippage or excessive tightness. After the installation is completed, a no-load test run is performed to check the rotation of the conveyor roller and ensure that the conveyor mechanism 2 can stably and reliably convey the plate.

[0026] A fixing plate 3 is installed on the outer wall of the middle section of the top of the frame 1. High-precision measuring tools are used to ensure the horizontality and verticality of the fixing plate 3. The fixing plate 3 is made of high-strength steel to withstand the weight of the powder coating assembly 7 and the force during the lifting process.

[0027] A hydraulic cylinder 5 is precisely installed on the top center outer wall of the fixed plate 3, so that the central axis of the hydraulic cylinder 5 coincides as much as possible with the center of gravity of the powder coating component 7 to ensure the stability of the lifting process. The output end of the hydraulic cylinder 5 passes through the fixed plate 3 and is firmly connected to the powder coating component 7 through the connecting frame 6. The structural design of the connecting frame 6 should take into account strength and stability to ensure that the force of the hydraulic cylinder 5 can be reliably transmitted.

[0028] Multiple telescopic rods 4 are evenly fixedly connected to the outer wall of the fixed plate 3. The telescopic ends of the telescopic rods 4 are connected to the top outer wall of the powder coating assembly 7. The telescopic rods 4 use hydraulic or pneumatic telescopic technology, which has good telescopic performance and stability. During installation, the initial length of the telescopic rods 4 is adjusted so that they are in a naturally extended state when the powder coating assembly 7 is in the initial position, and can play an auxiliary support and stabilizing role during the lifting and lowering process.

[0029] Install the powder coating box 701 and the paint spraying box 702 in their respective positions on the powder coating assembly 7, and connect them with bolts and sealing gaskets to ensure that the installation is firm and well-sealed to prevent paint leakage. The powder coating box 701 and the paint spraying box 702 are made of corrosion-resistant materials to adapt to different paint storage and use environments.

[0030] Multiple powder spraying pipes 7011 are installed below the powder spraying box 701, and multiple powder spraying nozzles 7012 are installed on the bottom outer wall of the powder spraying pipes 7011. The model and specifications of the powder spraying nozzles 7012 are selected according to the requirements of the powder spraying process to ensure that the powder coating can be sprayed evenly.

[0031] Similarly, multiple paint spray tubes 7021 are installed below the paint spray box 702, and multiple paint spray nozzles 7022 are installed on the bottom outer wall of the paint spray tubes 7021. The design of the paint spray nozzles 7022 should meet the requirements of paint spraying and be able to achieve a uniform and delicate spraying effect.

[0032] When installing the spraying assembly, fix the two pumps 14 on the outer wall of the powder spraying box 701 and the paint spraying box 702 on opposite sides. The installation position of the pumps 14 should facilitate the connection of pipes and maintenance. The suction end of the pumps 14 is connected to the bottom inner cavity of the powder spraying box 701 and the paint spraying box 702 through the extraction pipe 16. The extraction pipe 16 is made of corrosion-resistant and wear-resistant pipe material to ensure that there will be no leakage or blockage during long-term use.

[0033] The output end of the pump 14 is connected to the connecting pipe 8 through the delivery pipe 15. The diameter of the delivery pipe 15 and the connecting pipe 8 are reasonably selected according to the flow rate and pressure of the pump 14 to ensure that the paint can be delivered smoothly. One end of multiple powder spraying pipes 7011 and multiple paint spraying pipes 7021 is rotatably connected to the outer wall of two connecting pipes 8. The rotatable connection part adopts a precision bearing or joint structure to ensure that the powder spraying pipes 7011 and paint spraying pipes 7021 can rotate flexibly, while ensuring the sealing of the connection.

[0034] Fixing brackets 9 are fixedly connected to one side of the outer wall of the powder spraying box 701 and the paint spraying box 702 respectively. The fixing brackets 9 are made of high-strength metal material and have sufficient strength and rigidity. Multiple bearing seats 10 are evenly fixedly connected to the bottom outer wall of the two fixing brackets 9. The installation position of the bearing seats 10 should correspond to the position of the powder spraying pipe 7011 and the paint spraying pipe 7021.

[0035] A connecting shaft 11 is fixedly connected to one end of multiple powder spraying tubes 7011 and multiple paint spraying tubes 7021 away from the connecting pipe 8. The connecting shaft 11 is connected to the powder spraying tubes 7011 and paint spraying tubes 7021 by key connection or welding to ensure a firm connection. The connecting shaft 11 is rotatably connected to the inner wall of the shaft seat 10. A high-precision bearing is installed in the shaft seat 10 to ensure that the connecting shaft 11 can rotate flexibly.

[0036] Electric push rods 12 are fixedly installed below the opposite ends of the two fixed brackets 9. The installation position of the electric push rods 12 should ensure that their output ends can effectively push the push rod 121. The output ends of the electric push rods 12 are fixedly connected to the push rod 121. Multiple connecting blocks 122 are fixedly connected to the outer wall of the push rod 121. Multiple connecting rods 13 have movable grooves 131 on their outer walls. The connecting blocks 122 are movably connected inside the movable grooves 131. The movable connection should ensure that the connecting blocks 122 can slide flexibly in the movable grooves 131, and at the same time have a certain limiting function to prevent the connecting blocks 122 from disengaging from the movable grooves 131. The connecting rods 13 are fixedly connected to the connecting shaft 11 to ensure that the action of the electric push rods 12 can be transmitted to the powder spraying tube 7011 and the paint spraying tube 7021 through the push rod 121, connecting blocks 122, connecting rods 13 and connecting shaft 11, so as to realize the angle adjustment of the powder spraying tube 7011 and the paint spraying tube 7021.

[0037] Inlet ports 17 are respectively provided at appropriate positions on the outer walls of powder spraying box 701 and paint spraying box 702. The inlet ports 17 adopt a structural design with good sealing performance and are equipped with a sealing cover or valve (not shown in the figure). The size of the inlet ports 17 should facilitate the addition of paint and the connection of conveying equipment, and at the same time ensure that no paint leakage occurs during the operation of the equipment.

[0038] The implementation principle of the integrated powder spraying and painting device for sheet metal processing in this application embodiment is as follows: the sheet metal to be powder sprayed is placed at the starting end of the conveying mechanism 2, ensuring that the placement direction of the sheet metal is correct and the position is centered, and the conveying mechanism 2 is started so that the sheet metal is conveyed towards the powder spraying and painting component 7 at a set speed.

[0039] When the board is close to the bottom of the powder coating component 7, the hydraulic cylinder 5 is operated by the control system to lower the powder coating component 7 to a suitable powder coating height. This height is adjusted according to the thickness of the board and the requirements of the powder coating process. Generally, the distance between the powder nozzle 7012 and the surface of the board is maintained between 100-200 mm.

[0040] When the powder coating assembly 7 reaches the predetermined height, the pump 14 corresponding to the powder coating box 701 is started. The pump 14 extracts the powder coating in the powder coating box 701 and transports it through the pipeline to the powder coating nozzle 7012, which is then evenly sprayed onto the surface of the board.

[0041] Based on the shape and size of the board, the electric push rod 12 is operated by the control system to adjust the angle of the powder spraying tube 7011 so that the powder spraying nozzle 7012 can be better aligned with the surface of the board, ensuring that the powder coating can be evenly covered on all parts of the board.

[0042] After the board passes through the powder coating component 7, the powder coating operation is completed. The control system operates the hydraulic cylinder 5 to raise the powder coating component 7 to the initial position, waiting for the next powder coating operation.

[0043] The powder-coated board continues to be conveyed forward on the conveyor mechanism 2, or the board to be painted is placed directly on the conveyor mechanism 2 for conveying. When the board reaches below the powder coating component 7, the hydraulic cylinder 5 is operated by the control system to lower the powder coating component 7 to a suitable painting height. Generally, the distance between the spray nozzle 7022 and the surface of the board is between 100-180 mm.

[0044] Start the pump 14 corresponding to the paint spraying box 702. The pump 14 extracts the paint from the paint spraying box 702 and delivers it through the pipeline to the spray nozzle 7022, which is then sprayed evenly onto the surface of the board.

[0045] Based on the shape and size of the board, the electric push rod 12 is operated by the control system to adjust the angle of the paint spray tube 7021 so that the paint spray nozzle 7022 can be better aligned with the surface of the board, ensuring that the paint coating can be evenly covered on all parts of the board. After the board passes through the powder coating assembly 7, the painting operation is completed. The hydraulic cylinder 5 is operated by the control system to raise the powder coating assembly 7 to the initial position.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
