[0026] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figures 1-6 As shown, the utility model provides: a wood panel powder spraying and recycling moisture-proof agglomeration type coating equipment, including a main body 1 and a spraying assembly 11 arranged on the top of the main body 1, the spraying assembly 11 includes a powder supply box 113 for storing paint powder, the powder supply box 113 is provided with a stirring assembly 114 capable of stirring the paint powder, the stirring assembly 114 includes a connecting shaft 1142 and connecting members 1143 distributed around the connecting shaft 1142, and a nozzle 1144 is installed on the connecting member 1143, the main body 1 is also provided with a recovery device 13, the recovery device 13 absorbs the sprayed paint powder and feeds The paint powder is heated to evaporate the water in the paint powder. The recovery device 13 draws the paint powder into the connecting shaft 1142 and sprays it from the nozzle 1144. The connecting shaft 1142 is hollow for the paint powder to pass through. The connecting shaft 1142 is connected to the connecting piece 1143 so that the paint powder is sprayed from the nozzle 1144. The core of the stirring assembly 114 lies in the connecting shaft 1142 and the connecting pieces 1143 evenly distributed around it. The connecting shaft 1142 serves as a channel for the transmission of the paint powder. The hollow design facilitates the backflow of the paint powder and ensures that the paint powder can flow smoothly from the connecting shaft 1142 to each nozzle 1144. The stirring assembly 114 also includes a first rotary drive member 1141, which is installed outside the powder supply box 113 and is used to drive the connecting shaft 1142 to rotate.

[0028] First rotary drive member 1141, serving as the power source for stirring assembly 114, is mounted outside powder supply box 113 and connected to connecting shaft 1142. Driven by first rotary drive member 1141, connecting shaft 1142 and its connecting member 1143 rotate continuously and stably, thereby continuously stirring the paint powder within powder supply box 113 and effectively preventing the paint powder from clumping.

[0029] During use, the first rotating drive member 1141 rotates the connecting shaft 1142, and then rotates the connecting member 1143. When the connecting member 1143 rotates, the coating powder is continuously stirred, and then cooperates with the recovery device 13 to heat the coating powder and draw the coating powder into the connecting shaft 1142 and spray it out from the nozzle 1144, so that the coating powder in the powder supply box 113 is continuously moving, so that the hot air and the coating powder are fully mixed, and then the moisture is separated from the coating powder, thereby achieving the effect of dehumidifying the coating powder, and then the air and moisture are discharged to the outside of the powder supply box 113.

[0030] The recovery device 13 includes a hopper 131 installed at the bottom of the main body 1 and a heater 134 for heating the paint powder. The recovery device 13 also includes an air suction port 133 installed on the side of the main body 1. The bottom of the hopper 131 is connected to a first pipe 132, and one end of the air suction port 133 is connected to a second pipe 135. The first pipe 132 and the second pipe 135 are interconnected. The first pipe 132 and the second pipe 135 are both interconnected with the heater 134. The heater 134 is used to heat and evaporate the moisture in the paint powder. The heater 134 is also equipped with a temperature sensor for detecting the temperature. The heater 134 can heat the paint powder quickly and evenly, so that the moisture therein evaporates quickly. A high-precision temperature sensor is also installed inside the heater 134, which can monitor the temperature changes during the heating process in real time to ensure that the paint powder is heated within an appropriate temperature range, thereby avoiding the problem of paint powder quality degradation due to excessively high or low temperature.

[0031] During operation of the recovery device 13, the paint powder enters the heater 134 through the first pipe 132 for heating. The heated paint powder is then returned to the powder supply box 113 of the spray assembly 11 through the second pipe 135, thus achieving paint powder recycling. Simultaneously, a temperature sensor monitors temperature changes within the heater 134 in real time, ensuring a stable and controllable heating process.

[0032] The recovery device 13 also includes a negative pressure fan 137, the air inlet of the negative pressure fan 137 is connected to the third pipe 136, one end of the third pipe 136 is connected to the heater 134, the air outlet of the negative pressure fan 137 is connected to the fourth pipe 138, one end of the fourth pipe 138 is movably connected to one end of the connecting shaft 1142, and the negative pressure fan 137 draws the paint powder into the connecting shaft 1142 so that the paint powder flows back to the powder supply box 113.

[0033] When negative pressure blower 137 is activated, it generates a strong negative suction force, drawing the paint powder from heater 134 into the blower through third conduit 136. Subsequently, under the action of negative pressure blower 137, the paint powder is transported back to powder supply box 113 of spray assembly 11 through fourth conduit 138 connected to its outlet. One end of fourth conduit 138 is flexibly connected to one end of connecting shaft 1142. This flexible connection prevents fourth conduit 138 from rotating with connecting shaft 1142.

[0034] The top of the powder supply box 113 is also provided with a feed port 1131, and a detachable filter element 115 is embedded in the feed port 1131. The filter element 115 is used to prevent the paint powder from leaking out of the feed port 1131. When the filter element 115 is taken out of the feed port 1131, it can be used to add paint powder.

[0035] When adding paint powder, the user simply removes the filter element 115 from the feed port 1131 to conveniently add the paint powder. After adding the paint powder, the filter element 115 is reinstalled into the feed port 1131 to continue to prevent the paint powder from leaking, maintain stable quality, and allow moisture to escape.

[0036] The spraying assembly 11 includes a first moving mechanism 111, which is longitudinally arranged on the top of the main body 1. The first moving mechanism 111 is used for the powder supply box 113 to reciprocate along the length direction of the first moving mechanism 111.

The bottom of the powder supply box 113 is also provided with a second moving mechanism 112 through a support frame. A spray head 118 is provided on the second moving mechanism 112, and the second moving mechanism 112 is used to drive the spray head 118 moves along the length direction of the second moving mechanism 112 to spray the surface of the board. The second moving mechanism 112 has various driving modes, which can be motor-driven, hydraulic-driven or pneumatic-driven, etc. The specific selection depends on the actual needs of the equipment and the working environment, thereby achieving comprehensive and uniform spraying of the surface of the wooden board. A spray pump 116 is also installed at the bottom of the powder supply box 113, and one end of the spray pump 116 is connected to a nozzle 117, and one end of the nozzle 117 is fixedly connected to the spray head 118. The spray pump 116 draws the paint powder in the powder supply box 113 into the spray head 118 and sprays it onto the surface of the board. After the spray pump 116 is started, it can draw in the paint powder in the powder supply box 113 and transport it to the spray head 118 through the nozzle 117, and finally spray it onto the surface of the board.

[0037] By introducing the design of the first moving mechanism 111 and the second moving mechanism 112, and the coordinated action of the spray pump 116 and the spray head 118, the spray component 11 of the wood board powder spraying and recovery anti-moisture agglomeration coating equipment realizes the automation, efficiency and precision of the paint powder spraying process.
