[0023] The transmission mechanism 4 includes a disc 401 and a driving wheel 402, and the disc 401 is fixedly connected to the upper end of the output shaft of the motor 3, and the driving wheel 402 is installed at the edge of the upper surface of the disc 401, so that the motor 3 drives the transmission mechanism 4, so that the filter screen 11 moves back and forth to screen the sand material.

[0024] The driving wheel 402 and the driving frame 7 are in close contact with each other, and the transmission plate 6 and the positioning arm 5 on the side of the driving frame 7 are slidably arranged, so that the motor 3 drives the disc 401 to rotate, so that the disc 401 drives the driving wheel 402 to rotate around the longitudinal center line of the disc 401, thereby driving the driving frame 7 to move back and forth, so that the driving frame 7 drives the transmission plate 6 to move back and forth relative to the positioning arm 5.

[0025] The support wheel 8 and the bottom plate 1 are fitted together, the filter cartridge 9 and the filter frame 10 form a sliding structure, and the filter cartridge 9 and the grip plate 12 are fitted together, so that the transmission plate 6 can drive the filter cartridge 9 to move back and forth through the support wheel 8. At this time, the support wheel 8 rolls relative to the bottom plate 1, and it is convenient for the user to move the filter frame 10 for disassembly and assembly of the filter frame 10. At the same time, the filter frame 10 is mounted on the filter cartridge 9 through the grip plate 12.

[0028] Working principle: When using the anti-clogging sand filter device for the sand printer, first Figure 1-5 As shown, the user pours the sand material to be filtered into the filter frame 10, and the material is accumulated on the filter screen 11. Then the user starts the motor 3 and the screw conveyor 14, and then the motor 3 drives the disc 401 to rotate, and then the disc 401 drives the driving wheel 402 to rotate around the longitudinal center line of the disc 401, and then the driving wheel 402 drives the driving frame 7 to move back and forth, and as the driving frame 7 moves, the driving frame 7 drives the transmission plate 6 to slide relative to the positioning arm 5, and then the driving frame 7 drives the supporting wheel 8 to roll back and forth relative to the bottom plate 1, and then the supporting wheel 8 drives the filter cartridge 9 to move back and forth , and as the filter cartridge 9 moves, the filter cartridge 9 drives the positioning rod 16 to slide back and forth relative to the rod sleeve 15, and at the same time the positioning rod 16 drives the spring 17 to deform back and forth, and then the filter cartridge 9 drives the filter frame 10 and the filter screen 11 to move back and forth, so as to screen the material accumulated on the filter screen 11, and then the screened material falls into the screw conveyor 14, and then the screw conveyor 14 conveys the screened sand material to the sand printer for use, and the fineness and uniformity of the screened material are improved, thereby avoiding the blockage of the sand printer, and when the filter screen 11 needs to be cleaned, such as Figure 2 and Figure 4-5 As shown, the user turns off the motor 3 and the screw conveyor 14, and then the user rotates the knob 13. Next, the knob 13 moves relative to the grip plate 12 to disengage from the filter cartridge 9. Next, the user holds the grip plate 12 to move the filter frame 10 upward so that the filter frame 10 is separated from the filter cartridge 9, thereby completing the disassembly of the filter screen 11, making it easy to fully clean the filter screen 11, thereby preventing impurities from accumulating on the filter screen 11 and affecting the normal use of the device.
