As shown in the figure, the device includes: a base 100; a transmission component disposed on the base 100, the transmission component being used to transport the ceramic tile to be sprayed; a processing head 200, which is vertically and flexibly disposed on the base 100, the processing head 200 being located above the transmission component; the processing head 200 includes a powder tank 210 and a plurality of arrayed discharge ports 220 disposed at the bottom of the powder tank 210; an execution component including an actuator 310 disposed on each discharge port 220 and a control unit, the control unit being electrically connected to the actuator 310; and a controller 400, which is signal-connected to the transmission component and the control unit respectively. By inputting the pattern to be processed into the controller 400, the controller 400 controls the conveying speed of the conveying component and the opening and closing time, opening frequency, and opening size of the feeding port 220 according to the pattern, so as to realize customized spraying of tiles. By suspending the processing head 200 above the conveying component and using an independently controlled array of feeding ports 220, and through the dynamic coordinated control of the actuator and the conveying component, the powder can accurately cover a specific area of ​​the dynamically moving tile surface, which significantly improves the accuracy and efficiency of the tile powder spraying process. Customized spraying of tile patterns can be realized to meet the innovation requirements of new products.

[0024] See Figure 2 Preferably, the machine head is provided with multiple equidistant discharge troughs; the discharge troughs are connected by connectors; colored powder, glossy powder and matte powder are placed in the multiple discharge troughs respectively.

[0025] Preferably, the controller 400 rasterizes the pattern into bitmap data and optimizes the bitmap pixels by partitioning them according to the size of the feed nozzle, generating a control data stream that includes the feed nozzle switching sequence, opening and closing frequency, and opening size.

[0026] Preferably, the opening size of the feed port 220 is dynamically adjustable, and its adjustment range is calibrated according to the bitmap pixel partition size, and the minimum control pixel size is greater than 50 times the powder particle size.

[0027] Preferably, the base 100 is also provided with an electric protective cover 110 to protect the processing head 200 and prevent dust from contaminating the processing head 200.

[0028] See Figure 3 Furthermore, in this embodiment, the control unit includes multiple drive units 320 arrayed along the sidewall of the powder trough 210, each drive unit 320 independently controlling an actuator 310. The drive units are arrayed along the sidewall of the powder trough 210, ensuring that the response delay difference between each feed nozzle is <1ms. The independent drive mode avoids signal crosstalk, and arbitrary combinations of opening and closing can be achieved in the feed button matrix, supporting synchronous feeding of complex patterns.

[0030] Furthermore, in this embodiment, the actuator 310 includes: a drive cylinder 321 fixed to the side wall of the discharge port 220; and a baffle 322 connected to the power output end of the drive cylinder 321. The baffle 322 can extend horizontally to the discharge port of the discharge port 220. The drive cylinder 321 pushes the baffle 322 to horizontally cut off the discharge nozzle outlet. Its linear motion reduces the stroke by 50% compared to a rotary valve, improving working efficiency. The drive cylinder 321 is signal-connected to the actuator 320, and the extension length of the drive cylinder 321 is controlled by the actuator 320.

The servo motor 520 provides real-time feedback on the position of the conveyor belt through an encoder, achieving high speed control accuracy and ensuring minimal trigger position error at the discharge port 220 during high-speed operation, thereby improving the accuracy of continuous pattern seams.

[0035] See Figure 2 Furthermore, in this embodiment, the processing head 200 is connected to the base 100 via a linear guide rail 120, and the base 100 is provided with a lifting drive unit, the power output end of which is connected to the head; by setting a liftable head, the processing adaptability of the equipment is improved.

[0037] Preferably, the linear guide rails 120 are symmetrically arranged in four groups, the surface of the guide rails is provided with a wear-resistant coating, and the lifting stroke is 50mm to 300mm.

[0038] Preferably, the inner wall of the powder trough 210 is provided with a moisture-proof coating, and the lower part of the powder trough 210 is provided with an anti-accumulation slope. The anti-accumulation slope causes the powder to automatically slide towards the center in the trough due to gravity, eliminating residue at the four corners; the anti-accumulation coating is a polytetrafluoroethylene coating, which can reduce the adhesion of powder in the powder trough 210.

[0039] As can be seen from the above, the programmable powder spraying device of this utility model achieves customized powder coating of tiles by inputting the pattern to be processed into the controller, which controls the conveying speed of the conveying component and the opening and closing time, opening frequency, and opening size of the feeding port according to the pattern; by suspending the processing head above the conveying component and using an independently controlled feeding port array, and through the dynamic coordinated control of the actuator and the conveying component, the powder can accurately cover a specific area of ​​the dynamically moving tile surface, significantly improving the accuracy and efficiency of the tile powder coating process; it can realize customized powder coating of tile patterns and meet the innovation requirements of new products.
