[0032] Specifically, the collecting box 1 is used to collect and process the powder generated by 3D printing. Under the action of the dual-axis motor 17, the transmission rod 16 can be driven to rotate, so that the transmission rod 16 drives the fixed eccentric wheel 15 to rotate, so that the eccentric wheel 15 hits the bottom of the lifting plate 14, so that the lifting plate 14 pushes the lifting rod 11 to slide inside the limit block 12. Under the limit of the limit block 12, the lifting rod 11 is prevented from deviating, resulting in the failure of the entire structure of the lifting rod 11, thereby driving the rotation of the lifting rod 11 and the T-shaped block 10, so that the T-shaped block 1 0 slides inside the T-shaped groove 9, thereby causing the rotating plate 8 to rotate, and then the rotating plate 8 drives the connecting rod 27 to rotate, so that the connecting rod 27 slides along the outer wall of the arc groove 26, thereby driving the rotation of the filter screen 25, causing the filter screen 25 to vibrate to a certain extent, so that the powder can be shaken and filtered to prevent the powder from clogging the filter screen 25, so that the qualified powder will enter the collection box 2 through the filter screen 25, and the unqualified powder will enter the dual-axis motor 17 through the square slot of the collection box 1 under the shaking of the filter screen 25.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The cleaning component includes a printing chamber 3, which is fixedly connected to the top of the collecting box 1, a single-axis motor 21 is fixedly connected to the outer side of the printing chamber 3, a threaded rod 22 is fixedly connected to the output end of the single-axis motor 21, the outer thread of the threaded rod 22 is threadedly connected to a threaded block 23, the outer side of the threaded block 23 is fixedly connected to a moving plate 4, the inner side of the moving plate 4 is slidably connected to a brush plate 29, the outer side of the brush plate 29 is fixedly connected to a spring 28, the inner side of the printing chamber 3 is fixedly connected to a fixed rod 5, the outer side of the fixed rod 5 is slidably connected to a sliding block 24, the outer side of the sliding block 24 is fixedly connected to the outer side of the moving plate 4, one end of the spring 28 is fixedly connected to the outer side of the brush plate 29, the other end of the spring 28 is fixedly connected to the inner wall side of the moving plate 4, and the inner side of the printing chamber 3 is slidably connected to a printing table 6.

[0034] Specifically, the printing chamber 3 is the printer body. When 3D printing is required, printing will be performed on the top surface of the printing table 6. After printing, the generated powder will fall on the top of the printing table 6 and may fall into the interior of the printing chamber 3. At this time, by starting the single-axis motor 21, under the action of the output end of the single-axis motor 21, the threaded rod 22 is driven to rotate, and the threaded block 23 performs threaded movement along the outside of the threaded rod 22 and slides inside the collection box 1, thereby driving the movement of the movable plate 4. The internal sliding connection of the movable plate 4 is provided with a brush plate 29. Under the spring action of the spring 28, the brush plate 29 can be close to the top surface of the collection box 1, so that the powder on the top surface of the collection box 1 can be cleaned, so that the powder passes through the square groove on the top of the collection box 1 and falls into the interior of the collection box 1. Under the cooperation of the fixed rod 5 and the sliding block 24, the movable plate 4 can slide stably on the top of the collection box 1.

[0035] Reference Figure 2 A blower 20 is fixedly connected to one side of the outside of the printing chamber 3 , a filter box 19 is fixedly connected to the input end of the blower 20 , and an air outlet pipe 7 is fixedly connected to the output end of the blower 20 .

[0036] Specifically, the powder on the top of the printing table 6 needs to be blown down to the inside of the printing chamber 3, and then the inside of the printing chamber 3 is cleaned by the movable plate 4. At this time, the blower 20 is started, and the air passes through the filter box 19 under the action of the blower 20. The dust is filtered under the filtration of the filter box 19, and then input into the air outlet pipe 7 under the action of the output end of the blower 20, so that the powder on the surface of the printing table 6 and the powder in the printing chamber 3 can be blown and cleaned, and then cleaned through the movable plate 4, so that the powder can be cleaned and collected.

[0037] Working principle: When it is necessary to recycle the dust inside the printing room 3 and the powder on the surface of the printing table 6, the blower 20 is started intermittently. Under the action of the input end of the blower 20, the outside air enters the interior of the printing room 3, and the air passes through the filter box 19 and enters the blower 20. Under the action of the output end of the blower 20, the air passes through the air outlet pipe 7, so that the interior of the printing room 3 can be blown, so that the powder inside the printing room 3 and the printing table 6 is blown up, and the powder slowly falls and passes through the collection box 1. The multiple square grooves on the top enter the interior of the collecting box 1, while the powder that has not entered the interior of the collecting box 1 and is attached to the top surface of the collecting box 1, at this time, by starting the single-axis motor 21, under the action of the output end of the single-axis motor 21, the threaded rod 22 is driven to rotate, so that the threaded block 23 performs a threaded motion along the outside of the threaded rod 22, thereby driving the movement of the moving plate 4, and under the action of the spring 28, the brush plate 29 can be closely attached to the top surface of the collecting box 1, so that the powder on the top surface of the collecting box 1 is cleaned by the brush plate 29 and passes through the square grooves on the top surface of the collecting box 1 Enter the interior of the collecting box 1, so as to complete the cleaning of the powder inside the collecting box 1. Because the powder may be insufficiently used during use, some powder may be sintered. When the used powder needs to be recycled, it needs to be filtered. At this time, by starting the double-axis motor 17, under the action of the double-axis motor 17, the transmission rod 16 is driven to rotate, so that the transmission rod 16 drives the rotation of the eccentric wheel 15, so that the eccentric wheel 15 hits the lifting plate 14, and then drives the lifting of the lifting rod 11, so that the lifting rod 11 and the T-shaped block 10 rotate, so that the T-shaped block 10 slides along the inside of the T-slot 9, thereby pushing the rotating plate 8 to rotate, so that the rotating plate 8 drives the connecting rod 27 to rotate, and the connecting rod 27 drives the filter screen 25 to rotate, so that the filter screen 25 can perform a shaking filter on the powder, and at the same time prevent the filter screen 25 from being blocked, so that qualified powder falls into the collection box 2 through the filter screen 25, and unqualified powder will enter the classification box 18 under the shaking of the filter screen 25, so that the recovered powder can be classified, which is convenient for subsequent staff to use and process qualified and unqualified powder.
