[0026] An anti-dust adhesion component is provided inside the shell 1, and the anti-dust adhesion component includes a rotating column 29 rotatably connected to the top of the fixed shell 6, and the output shaft end of the stepper motor 8 is transmission-connected to the outer side of the rotating column 29 with a synchronous belt 30, and the end of the rotating column 29 away from the synchronous belt 30 is fixedly connected to a crank 31, and the inner wall of the shell 1 is rotatably connected to a swing rod 32, and an opening 33 is opened on the swing rod 32, and the end of the crank 31 away from the rotating column 29 is slidably adapted to the opening 33.

[0027] The anti-dust adhesion component also includes a partition 34 fixedly connected to the inner wall of the shell 1, and a filter 35 is fixedly connected to the top of the partition 34, and the filter 35 is also fixedly connected to the inner wall of the shell 1, and a connecting rod 2 36 is fixedly connected to the side wall of the filter 35. The connecting rod 2 36 is located on the movement path of the opening 33. The material of the connecting rod 2 36 is a carbon fiber composite material, which can effectively transfer the force generated by the opening 33 hitting the connecting rod 2 36 to the filter 35, thereby driving the filter 35 to resonate to prevent dust adhesion, and at the same time avoid direct knocking and damage to the filter 35. The bottom of the inner cavity of the shell 1 is fixedly connected to a collecting bin 37, and the outer side of the collecting bin 37 is slidably adapted to the sliding opening 5.

[0028] The above implementation works as follows: The initialization steps are as follows: During the process of processing putty powder by the putty powder processing device, a large amount of putty powder will be mixed in the air to form dust. The staff turns on the negative pressure fan 3, so that the negative pressure fan 3 draws the dust generated in the putty powder processing device into the interior of the outer shell 1 through the air inlet 4. The negative pressure fan 3 continuously draws the air out of the outer shell 1. At this time, the dust is filtered by the filter 35 and cannot pass through the filter 35, and the air is sucked to the outside of the outer shell 1 by the negative pressure fan 3.

[0029] The working steps are as follows: The working steps of the dust compaction component are as follows: When the air without putty powder is sucked to the outside of the housing 1 by the negative pressure fan 3, a large amount of putty powder adheres to the filter screen 35 at this time, thus playing a role in separating the putty powder from the air in the first step. The large amount of putty powder on the filter screen 35 moves vertically downward due to its own gravity, so the fixed housing 1 below the filter screen 35 catches all the putty powder through the notch 7 opened on it. At the same time, the putty powder enters the notch 15 and contacts the outer arc surface of the arc-shaped plate 14. At this time, after the first stepping motor 8 is powered on, the output shaft end of the first stepping motor 8 drives the cylinder 9 to rotate synchronously, and each time the first stepping motor 8 drives the notch 15 on the cylinder 9 to rotate to the porous sponge 17, it stops. When the first stepping motor 8 drives the notch 15 on the cylinder 9 to rotate to the porous sponge 17, at this time the cylinder 9 also drives the circular plate to rotate synchronously, so the circular plate drives the second stepping motor 10 to rotate synchronously. Therefore, when the first stepping motor 8 stops rotating, at this time the second stepping motor 10 is powered on and its output shaft end starts to rotate the threaded rod 11, so the rotation of the threaded rod 11 drives the circular sleeve 1 to move away from the second stepping motor 10. The sliding of the circular sleeve 1 drives the connecting rod 13 to move synchronously. At this time, one end of the connecting rod 13 away from the circular sleeve 1 slides inside the notch 15, so the connecting rod 13 pushes the arc-shaped plate 14 to slide away from the threaded rod 11 inside the cavity of the notch 15. Therefore, the arc-shaped plate 14 pushes the putty powder located in the notch 15 to slide inside the notch 15. When the putty powder in the inner cavity of the notch 15 moves and touches the porous sponge 17, the putty powder is compacted.

[0030] Through the setting of the compaction component, it can make the volume of the dust shrink greatly after compaction, thus firstly increasing the collected weight of the putty powder. At the same time, it enables the connecting rod 2 to store more putty powder, thereby reducing the frequency of replacing the connecting rod 2. At the same time, it avoids the secondary dust generation of loose putty powder during transportation or transfer due to vibration and air flow. After compaction, it forms a block or cake shape, and the surface is more stable, which can reduce dust dispersion.

[0031] The working steps of the coarse dust crushing component are as follows: After the putty powder in the inner cavity of the notch 15 is compacted, it continues to push the porous sponge 17 to slide into the inner cavity of the fixed housing 2. The porous sponge 17 drives the sliding plate 18 to move synchronously. At this time, both the porous sponge 17 and the sliding plate 18 slide on the first fixed rod 20 in the direction close to the fixed plate 19. At this time, the first fixed rod 20 continuously passes through the sliding plate 18 and the porous sponge 17. Firstly, it avoids the retention of putty powder in the pores of the porous sponge 17. Secondly, when the first fixed rod 20 completely penetrates the porous sponge 17, at this time the multiple first fixed rods 20 start to contact the putty powder, thus crushing the coarser or agglomerated putty powder and further increasing the collected weight of the putty powder.

[0032] Meanwhile, the sliding plate 18 slides on the first fixed rod 20 in the direction close to the fixed plate 19, and the sliding plate 18 drives the sliding rod 21 to move synchronously. Therefore, the sliding rod 21 drives the second round sleeve 22 to move away from the fixed plate 19 and compress the first spring 23. When the staff observes that the sliding rod 21 no longer slides out of the second fixed housing 16, at this time, the staff controls the second stepper motor 10 to start reversing. At this time, the rotation of the threaded rod 11 drives the first round sleeve 12 threadedly connected thereto to move in the direction close to the second stepper motor 10. The sliding of the first round sleeve 12 drives the first connecting rod 13 to rotate synchronously. At this time, one end of the first connecting rod 13 away from the first round sleeve 12 slides inside the notch 15. The first connecting rod 13 drives the arc-shaped plate 14 to slide in the direction close to the threaded rod 11 inside the notch 15. As described above, at this time, the arc-shaped plate 14 no longer abuts against the putty powder in the inner cavity of the notch 15. Therefore, the putty powder in the inner cavity of the notch 15 no longer abuts against the porous sponge 17. The compressed first spring 23 pushes the second round sleeve 22 to move in the direction close to the fixed plate 19 through the elastic expansion force. At this time, the second round sleeve 22 drives the sliding rod 21 to move synchronously and slide in the fixed plate 19. The sliding rod 21 pushes the sliding plate 18 to slide away from the fixed plate 19 inside the notch 15. The sliding plate 18 drives the porous sponge 17 to move synchronously. Thus, the porous sponge 17 pushes the putty powder into the inner part of the notch 15. At the same time, the first stepper motor 8 drives the cylinder 9 to start rotating again. When the notch 15 on the cylinder 9 passes through the bottom of the first fixed housing 6, the putty powder inside the notch 15 falls into the second connecting rod 36 under the action of gravity. Thus, the second connecting rod 36 continuously collects this putty powder. Thus, the dust continuously enters the inner cavity of the housing 1. And so on. When each notch 15 rotates to the bottom of the first fixed housing 6, it will put the putty powder into the second connecting rod 36.

[0033] The working principle of the exhaust component is shown in the figure: When the sliding plate 18 slides on the first fixed rod 20 in the direction close to the fixed plate 19 and drives the sliding rod 21 to move synchronously, at this time, the putty powder is squeezed and compressed, and the air remaining in its gaps is squeezed through the porous sponge 17 and the sliding plate 18 into the air outlet pipe 24. At this time, the air pressure between the air outlet pipe 24 and the umbrella-shaped sliding column 28 increases, thereby pushing the umbrella-shaped sliding column 28 to move away from the fixed ring 25 and compress the second spring 27. When the atmospheric pressure between the air outlet pipe 24 and the umbrella-shaped sliding column 28 is the same as the air outside the housing 1, the compressed second spring 27 pushes the umbrella-shaped sliding column 28 to move in the direction close to the fixed ring 25 through the elastic expansion force. The umbrella-shaped sliding column 28 fits with the fixed ring 25 again, sealing the fixed ring 25. It should be noted that before the dust enters the housing 1, it is necessary to separate the air and the putty powder for the first time through the filter screen 35. Thus, in this step, not only the collection quality of the putty powder is improved, but also it can assist the negative pressure fan 3 to convert the gas in the inner cavity of the housing 1 with the outside.

[0034] The cooperation between the coarse dust crushing and the exhaust component not only crushes the coarser putty powder, but also discharges the air in the agglomerated putty powder. Firstly, it further assists in the compaction of the putty powder. Secondly, it improves the collection quality of the putty powder, avoids the reuse of the coarser putty powder, and at the same time prevents the air in the agglomerated putty powder from being unable to be discharged, resulting in secondary dust emission.

[0035] The working steps of the dust-proof adhesion component are as follows: With the operation of the first stepping motor 8 in the above working steps, each time the first stepping motor 8 rotates, the output shaft section of the first stepping motor 8 will drive the rotating column 29 to rotate clockwise in the same direction through the synchronous belt 30. Then, the rotation of the rotating column 29 drives the crank 31 to perform a clockwise circular motion with the center of the rotating column 29 as the axis. Thus, the end of the crank 31 away from the rotating column 29 continuously slides on the opening 33, and the crank 31 realizes the reciprocating swing of the swing rod 32 with the center of the connection between the swing rod 32 and the housing 1 as the axis by pushing the opening 33. Also, since the second connecting rod 36 is located on the movement path of the swing rod 32, the swing rod 32 continuously knocks on the second connecting rod 36 at this time. The second connecting rod 36 drives the filter screen 35 to resonate together. Thus, as described above, the vibration of the filter screen 35 shakes off the putty powder attached to it, and the shaken-off putty powder can repeat the above working steps to achieve the collection of the putty powder.

[0036] The setting of the dust-proof adhesion component can prevent a large amount of putty powder from staying or adhering to the filter screen 35 during the separation of air and putty powder, further improving the utilization rate of putty powder in the dust, and at the same time avoiding the blockage of the filter screen 35 caused by the putty powder, so that the separation of air and putty powder in the dust can continue.

[0037] When the collection bin 37 is filled with putty powder, the staff holds the collection bin 37 and slides it out of the notch 7, and then replaces the second connecting rod 36 to achieve the next collection of putty powder.
