Detailed Implementation

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] like Figure 1 and Figure 2 As shown, a paint production and processing device includes a working box 1, a powder feeding component, a spraying component, and a powder recovery mechanism. The powder feeding component is mounted above the working box via a support frame 2. The spraying component is connected to the powder feeding component and is located on one side of the working box 1. The spraying component includes an electrostatic spray nozzle 3, a spray gun controller 4, a spray gun bracket 5, and supporting rotating rollers 6. The electrostatic spray nozzle 3 is connected to the side of the working box 1 via the spray gun bracket 5. The spray gun controller 4 is connected to the electrostatic spray nozzle 3. Two supporting rotating rollers 6 are arranged side by side and rotate below the electrostatic spray nozzle 3. A drive component is connected to the lower part of the supporting rotating rollers 6. The powder recovery mechanism is located inside the working box 1. In practice, the working box 1 provides a closed working environment, reducing the scattering of the roll coating and protecting operators from dust damage. It also helps to improve spraying efficiency. As the foundation of the entire device, it supports and fixes other components. The electrostatic spray nozzle 3 on the spraying component uses electrostatic principles to better adsorb the roll coating onto the workpiece surface, improving the adhesion and uniformity of the coating. The spray gun controller 4 enables remote control of the spray gun, improving the safety and convenience of operation. The spray gun bracket 5 provides stable support and fixation for the electrostatic spray nozzle 3, ensuring the stability of the spraying process. The height and angle of the spray gun can be adjusted according to the spraying requirements. The support roller 6 supports and transports the workpiece, ensuring that the workpiece moves smoothly during the spraying process. The rotation ensures that the workpiece is sprayed evenly. The powder recovery mechanism includes a recovery hopper 7, a connecting frame 8, a cyclone separator 9, and a collection container 10. The recovery hopper 7 is connected to the side of the spray gun bracket 5. The connecting frame 8 is connected to the inside of the top of the work box 1. The cyclone separator 9 and the collection container 10 are fixed under the connecting frame 8. The cyclone separator 9 is connected to the recovery hopper 7, and the collection container 10 is connected to one side of the cyclone separator 9. The recovery hopper 7 collects powder that was not applied during the spraying process. Excess coil paint sprayed from the spray gun onto the workpiece is collected in the recovery hopper 7 and directed to the subsequent cyclone separator 9 for further processing. The connecting frame 8 provides stable support and fixation for the cyclone separator 9 and the collection container 10. The cyclone separator 9 separates the powder from the air in the powder-containing airflow from the recovery hopper 7 using centrifugal force. Larger powder particles are thrown against the wall of the separator and fall into the collection container 10 under the action of centrifugal force, while the air is discharged through the top of the cyclone separator. The collection container 10 stores the clean coil paint after being processed by the cyclone separator. This coil paint can be reused for subsequent spraying operations and prevents the powder from getting damp or contaminated.

[0017] like Figure 1 As shown, based on the above method, the powder feeding component further includes a powder storage tank 11, a powder conveying pump 12, and a conveying hopper 13. The conveying hopper 13 is mounted on the support frame 2, and the powder storage tank 11 is mounted on the conveying hopper 13. One side of the powder storage tank 11 is connected to the powder conveying pump 12. A powder flow controller 14 is mounted on the side of the conveying hopper 13. The powder storage tank 11 has sufficient capacity to store a sufficient amount of coil coating. The powder conveying pump 12 generates sufficient pressure to transport the coil coating through a pipeline to the spraying component, thereby achieving precise supply of the coil coating. The conveying hopper 13 is located between the powder storage tank and the spraying component, serving as a connection and transition. The coil coating in the powder storage tank 11 is guided to the powder conveying pump 12 and then transported to the spraying component. The powder flow controller 14 is used to precisely control the amount of coil coating conveyed.

[0018] like Figure 1 As shown, further based on the above method, a powder flow regulating valve 15 is installed below the cyclone separator 9. The powder flow regulating valve 15 regulates the flow rate of the recovered powder into the collection container 10, ensuring the stability and efficiency of the recovery process. It can be adjusted according to the actual recovery volume to avoid powder overflow or accumulation.

[0019] like Figure 2 As shown, based on the above method, the driving component further includes a fixed plate 16, a drive motor 17, and a connecting belt 18. The drive motor 17 is connected to the support rotating roller 6 below through the fixed plate 16, and the output end of the drive motor 17 is connected to the support rotating roller 6 through the connecting belt 18. The fixed plate 16 securely connects the drive motor 17 to the support rotating roller 6 below. The drive motor 17 drives the connecting belt 18 and the support rotating roller 6 to rotate together through the rotational motion of its output end.

[0020] like Figure 2 As shown, based on the above method, a control panel 19 is further provided on one side of the work box 1; the control panel 19 integrates all control functions into one, which is convenient for operators to centrally control and manage the entire spraying device, and automatically adjust the spraying and recycling process according to preset parameters.

[0021] like Figure 2 As shown, based on the above method, a further step is to provide an inclined plate 20 below the supporting rotating roller 6, which receives powder that has not been collected by the powder recovery mechanism.

[0022] In the specific operation of this new type of coating production and processing device, the operator first sets various parameters for spraying and recycling, such as spraying speed, powder flow rate, and recycling time, through the control panel 19. Sufficient MDF roll coating is pre-stored in the powder storage tank 11, and the powder conveying pump 12 is ready to start. The supporting rotating roller 6 is driven by the drive motor 17 via the connecting belt 18 and is in standby mode. The powder conveying pump 12 starts, conveying the roll coating in the powder storage tank 11 to the electrostatic spray nozzle 3 through the conveying hopper 13. The spray gun controller 4 controls the electrostatic spray nozzle 3 to perform spraying operations according to preset parameters. The roll coating is adsorbed onto the workpiece surface under electrostatic action. The workpiece is placed on two supporting rotating rollers 6, driven by the drive motor 17, so that the workpiece moves smoothly and is sprayed evenly during the spraying process. During the spraying process, excess roll coating that does not adhere to the workpiece is collected through the recycling hopper 7 and guided to the cyclone separator 9. The cyclone separator 9 starts, separating the powder in the powder-containing airflow from the air through centrifugal force. Larger powder particles are thrown against the wall and fall into the collection container 10, while air is discharged from the top of the cyclone separator. The powder flow regulating valve 15 adjusts the flow rate of the recovered powder into the collection container 10 according to actual needs, ensuring the stability and efficiency of the recovery process. Operators monitor various parameters of the spraying and recovery process in real time through the control panel 19, such as powder flow rate and recovery efficiency. If spraying or recovery parameters need to be adjusted, operators can make quick adjustments through the control panel 19. After spraying, the pure roll coating stored in the collection container 10 can be reused for subsequent spraying operations. If it is necessary to clean the inside of the work box 1, the work box door can be opened to clean the residual powder; the inclined plate 20 receives and collects powder that may not be completely collected by the powder recovery mechanism, preventing powder from scattering outside the work box. Regularly clean and maintain the spraying components, powder recovery mechanism, and drive components to ensure their normal operation and extend their service life. Check the accuracy and sensitivity of control components such as the powder flow controller 14 and the powder flow regulating valve 15, and calibrate or replace them if necessary. Through the above steps, this new type of paint production and processing device can efficiently and stably complete the spraying operation and effectively recycle unused roll paint, realizing the recycling of resources.
