[0043] Referring to Figures 4-7 As shown in the drawings, the upper end surface of the plurality of second support columns 601 is provided with a second sliding groove 607, and the upper end surface of the pair of second support columns 601 is connected with a sliding plate 602, and the sliding plate 602 is connected with the second support column 601, and the pair of sliding plates 602 slides up and down on the second support column 601 through the second sliding groove 607.

[0044] Referring to Figures 1-2 As shown in the drawings, the pair of opposite end surfaces of the automatic closing filter screen 5 are fixedly connected with one side end surface of the sliding plate 602, and the pair of sliding plates 602 are connected with a first driving motor 603 to control the up-down movement direction of the automatic closing filter screen 5. The material of the three-axis spraying gantry 6 is a gantry, which is more economical and practical than a mechanical arm. Specifically, when it is needed to move the material up and down, the automatic closing filter screen 5 needs to be moved upward or downward to be opened, and the automatic closing filter screen 5 is controlled to move upward or downward under the action of the first driving motor 603.

[0045] Referring to Figure 1As shown, the automatic closing filter screen 5 is provided with a taking groove near the side end face of the rotating feeding device 7, facilitating the operation of feeding and discharging.

[0049] Specifically, when the specification of the current product positioning tool 701 does not meet the specification of the material, the product positioning tool 701 needs to be detached and replaced with a product positioning tool 701 meeting the specification of the material. When the clamping column 706 on the connecting plate 703 moves away from the connecting column 705 on the supporting assembly 704, the product positioning tool 701 is removed. After the product positioning tool 701 meeting the specification of the material is replaced, the product positioning tool 701 is moved to the clamping column 706 to clamp the connecting column 705, and the clamping column 706 and the connecting column 705 are tightly fitted without gaps, so as to fix the product positioning tool 701 on the supporting assembly 704.

[0050] Figures 8-9As shown, a pair of product positioning tooling 701 is fixedly connected with a plurality of fixing plates 702, and a plurality of screw holes are formed in the fixing plates 702, so that when the material needs to be fixed on the product positioning tooling 701, the bolt can be penetrated through the material and the screw hole for fixing, and the material is fixed on the product positioning tooling 701.

[0051] Figures 8-9 As shown, the control cabinet 8 is located on one end face of the spraying protection room 2, and realizes overall control of the main body 1.

The control buttons on the control cabinet 8 are operated to control the equipment, so that the equipment can be controlled to automatically spray the water-based paint on the material in all directions, and the filtering and dust removing device 11 can remove dust during operation.

[0052] The working principle of the control cabinet 8 is that when the programmable logic controller is put into operation, its working process is generally divided into three stages, namely input sampling, user program execution and output refreshing three stages. The completion of the above three stages is called a scanning cycle. During the entire operation, the CPU of the PLC repeats the above three stages at a certain scanning speed.

[0053] In use, the user can control the control cabinet 8 to automatically close the filter screen 5 to a certain distance, and then place the material on the product positioning tooling 701, and then control the automatic closing filter screen 5 to move downward, and start the rotating feeding device 7 and the spray gun assembly 10 to start operation, and spray the material in all directions, and start the filtering and dust removing device 11 to remove the dust generated during the operation, reduce the harm of the dust generated during the processing to the body of the employee, and improve the working efficiency. Figure 1 As shown, when the material needs to be sprayed with water-based paint, the automatic closing filter screen 5 is first moved upward to a certain distance by controlling the control cabinet 8, and then the material is placed on the product positioning tooling 701, and then the automatic closing filter screen 5 is controlled to move downward, and the rotating feeding device 7 and the spray gun assembly 10 are started to operate, and the material is sprayed in all directions, and the filtering and dust removing device 11 is started to remove the dust generated during the operation, reduce the harm of the dust generated during the processing to the body of the employee, and improve the working efficiency.
