DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, an automatic cleaning device for 3D additive materials includes a cleaning box 1, a filter box 9 and a placement plate 2. A nozzle 3 is fixedly installed inside the cleaning box 1, the placement plate 2 is fixedly connected to the inside of the cleaning box 1, a displacement groove 11 is opened inside the placement plate 2, a clamping plate 10 is slidably connected inside the displacement groove 11, a clamping mechanism is provided at the bottom of the placement plate 2, the filter box 9 is fixedly connected to the bottom of the cleaning box 1, through holes 12 are equidistantly opened inside the cleaning box 1, a mounting plate 26 is slidably connected inside the filter box 9, a filter screen 14 is provided inside the mounting plate 26, a fixed block 8 is fixedly connected to one side of the filter box 9, a slide groove 21 is opened inside the fixed block 8, a limiting mechanism is provided inside the slide groove 21, a water outlet pipe 7 is fixedly connected to one side of the filter box 9, a booster water pump 6 is fixedly installed on one end of the water outlet pipe 7, a water inlet pipe 5 is fixedly connected to the output end of the booster water pump 6, and one end of the water inlet pipe 5 is fixedly connected to one side of the nozzle 3.

[0022] First, by placing the printed piece on the top of the placement plate 2, and then starting the clamping mechanism to drive the two clamping plates 10 to clamp and fix the outside of the printed piece, the problem of detachment under the flushing of high-pressure water is avoided, thereby increasing the stability of the device during flushing, and then the outside of the printed piece is flushed through the nozzle 3, and the waste water generated by the flushing flows into the top of the filter screen 14 inside the filter box 9 through the through hole 12, and then the waste water is filtered through the filter screen 14, and the filtered water enters the inside of the nozzle 3 from the outlet pipe 7 and the inlet pipe 5 through the booster water pump 6, thereby forming a circulating flushing, which saves water resources, and then when the filter screen 14 is replaced and cleaned, the fixing of the mounting plate 26 can be conveniently released by toggling the limiting mechanism, thereby pulling the mounting plate 26 to drive the filter screen 14 to detach from the inside of the filter box 9, and then when installing the filter screen 14, it is only necessary to insert the mounting plate 26 into the inside of the filter box 9, and it can be automatically fixed by the limiting mechanism, thereby increasing the convenience of the device.

[0023] like Figure 1-Figure 4 As shown, the clamping mechanism includes two first vertical plates 16, and the two first vertical plates 16 are fixedly connected to the bottom of the placement plate 2. A bidirectional screw rod 15 is rotatably connected between the two first vertical plates 16. A motor 13 is fixedly installed on one side of the cleaning box 1, and one end of the output shaft of the motor 13 is fixedly connected to one end of the bidirectional screw rod 15. The clamping mechanism also includes a displacement block 17, which is threadedly connected to the outer side of the bidirectional screw rod 15, and the top of the displacement block 17 is fixedly connected to the bottom of the clamping plate 10. The bottom of the placement plate 2 is fixedly connected with two second vertical plates 19, and a sliding rod 18 is fixedly connected between the two second vertical plates 19, and the outer side of the sliding rod 18 is slidably connected to the inside of the displacement block 17.

[0024] When clamping the printed workpiece, the output shaft of the starting motor 13 automatically drives the bidirectional screw 15 to rotate and drives the displacement block 17 to slide on the outside of the slide bar 18, and then the movement of the displacement block 17 can be limited by the slide bar 18, so as to avoid the problem of displacement of the displacement block 17. Then the displacement block 17 moves to drive the clamping plate 10 to approach the outside of the printed workpiece, and completes the fixation of the printed workpiece, thereby increasing the stability of the printed workpiece during flushing, and further increasing the practicality of the device.

[0025] like Figure 1-Figure 4As shown, the limiting mechanism includes a slider 20, which is slidably connected to the inside of the slide groove 21, and a spring 22 is fixedly connected between one side of the slider 20 and the inner wall of the slide groove 21. The limiting mechanism also includes a clamping block 23, which is slidably connected to the inside of the fixed block 8, and one end of the clamping block 23 is fixedly connected to one side of the slider 20. A clamping groove 4 is provided on one side of the mounting plate 26, and one end of the clamping block 23 extends to the inside of the clamping groove 4. A limiting groove 25 is provided on one side of the fixed block 8, and a limiting rod 24 is slidably connected to the inside of the limiting groove 25, and one end of the limiting rod 24 is fixedly connected to one side of the slider 20.

[0026] When replacing the filter 14, the limit rod 24 is pushed to slide inside the limit groove 25 and the slider 20 is driven to slide inside the slide groove 21, and then the block 23 is driven to disengage from the inside of the groove 4, thereby completing the release of the mounting plate 26, and then the filter 14 can be conveniently pulled out from the inside of the filter box 9. Then, when installing the filter 14, one side of the mounting plate 26 contacts the inclined surface of the block 23, thereby driving the block 23 to slide and driving the slider 20 to move to compress the spring 22. Then, when the groove 4 moves to one side of the block 23, the reaction force of the spring 22 drives the block 23 to directly enter the inside of the groove 4, thereby automatically completing the fixation of the mounting plate 26, thereby further increasing the practicality of the device.

[0027] The utility model provides an automatic cleaning device for 3D additive materials, and the specific working principle is as follows: first, by placing the printed work on the top of the placement plate 2, and then starting the output shaft of the motor 13 to automatically drive the bidirectional screw 15 to rotate and drive the displacement block 17 to slide on the outside of the slide bar 18, and then the movement of the displacement block 17 can be limited by the slide bar 18, so as to avoid the problem of displacement of the displacement block 17. Then the displacement block 17 moves and drives the clamping plate 10 to approach the outside of the printed work to complete the fixation of the printed work, thereby increasing the stability of the printed work during flushing, and then, the outside of the printed work is flushed through the nozzle 3, and the waste water generated by the flushing flows into the top of the filter screen 14 inside the filter box 9 through the through hole 12, and then the waste water is filtered through the filter screen 14, and the filtered water is then discharged from the outlet pipe 7 through the booster pump 6. The water inlet pipe 5 enters the interior of the nozzle 3, thereby forming a circulating flushing, which saves water resources. Then, when replacing and cleaning the filter 14, the limit rod 24 is toggled to slide in the limit groove 25 and drive the slider 20 to slide in the slide groove 21, and then drive the block 23 to disengage from the inside of the slot 4, thereby completing the release of the mounting plate 26, and then the filter 14 can be easily pulled out from the inside of the filter box 9. Then, when installing the filter 14, one side of the mounting plate 26 contacts the inclined surface of the block 23, thereby driving the block 23 to slide and driving the slider 20 to move to compress the spring 22. Then, when the slot 4 moves to one side of the block 23, the block 23 is driven directly into the inside of the slot 4 by the reaction force of the spring 22, thereby automatically completing the fixation of the mounting plate 26.
