[0017] As a further technical solution of the present invention, through holes are formed in the inner wall of the brush plate, and the through holes are uniformly arranged.

[0018] A preparation method of an ABS aqueous acrylic paint preparation device includes the following steps:

[0019] S1: When preparing the ABS waterborne acrylic paint, start the exhaust fan to create a negative pressure in the treatment tank, connect the guide pipe to introduce the gas in the preparation tank into the treatment tank, and filter it through the filter plate.

[0020] S2: The rotation of the exhaust fan drives the rotation of the rotating ring, the rotation of the rotating ring drives the rotation of the first gear, the rotation of the first gear drives the rotation of the first reciprocating lead screw, the rotation of the first reciprocating lead screw drives the reciprocating movement of the moving plate, the movement of the moving plate drives the movement of the tooth block seat, the movement of the tooth block seat drives the movement of the two groups of tooth blocks. When one group of tooth blocks moves, it drives the rotation of the second gear, the rotation of the second gear drives the rotation of the first rotating shaft, and the rotation of the first rotating shaft drives the rotation of the filter plate, so that each area has the opportunity to contact the waste gas. When one group of tooth blocks is reset, it slides into the interior of the tooth block seat under force, and the second gear does not rotate.

[0021] S3: When the other group of tooth blocks is reset and meshes with the third gear, it drives the third gear to rotate. The rotation of the third gear drives the rotation of the second reciprocating lead screw, and the rotation of the second reciprocating lead screw drives the reciprocating movement of the slider. The movement of the slider drives the movement of the brush plate, so that the brush plate reciprocates once at the bottom of the filter plate to clean it.

[0022] S4: When the first rotating shaft rotates, it drives the rotation of the rotating disk, and the rotation of the rotating disk drives the rotation of the convex block. When the convex block rotates to the lower part and contacts the brush plate, it drives the brush plate to move to one side. When the brush plate moves, it drives the connecting plate to slide inside the slider, and at the same time the spring is stressed to store elastic potential energy. When the convex block rotates and separates from the brush plate, the elastic potential energy is released by the spring to make the connecting plate move back to its original position, so that the brush plate reciprocates and vibrates, which helps to shake off the impurities inside the bristles at the top of the brush plate.

[0023] S5: Finally, the organic waste gas after being filtered by the filter plate is discharged from the device.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. Through the setting of the filtering component, when working, start the exhaust fan to create a negative pressure in the treatment tank, connect the guide pipe to introduce the gas in the preparation tank into the treatment tank, and discharge it from the device after filtering through the filter plate, preventing the direct emission of the organic waste gas generated during the preparation of the ABS waterborne acrylic paint from affecting the physical health of the staff and causing air pollution, and optimizing the production environment.

[0026] 2. Through the arrangement of the rotating assembly in the present invention, during operation, the rotation of the exhaust fan drives the rotation of the rotating ring, the rotation of the rotating ring drives the rotation of the first gear, the rotation of the first gear drives the rotation of the first reciprocating lead screw, the rotation of the first reciprocating lead screw drives the reciprocating movement of the moving plate, the movement of the moving plate drives the movement of the tooth block seat, the movement of the tooth block seat drives the movement of the tooth block, and when the tooth block moves, it drives the rotation of the second gear. The rotation of the second gear drives the rotation of the first rotating shaft, and the rotation of the first rotating shaft drives the rotation of the filter plate, enabling each area to have the opportunity to come into contact with the waste gas, avoiding the situation of excessive local filtration load, and thus improving the overall filtration efficiency.

[0027] 3. Through the arrangement of the cleaning assembly in the present invention, when another set of tooth blocks meshes with the third gear, it drives the third gear to rotate. The rotation of the third gear drives the rotation of the second reciprocating lead screw, the rotation of the second reciprocating lead screw drives the reciprocating movement of the slider, and the movement of the slider drives the movement of the brush plate, causing the brush plate to reciprocate once at the bottom of the filter plate to clean it, removing the particulate matter blocked in the pores, reducing the frequency of manual maintenance, and ensuring the filtration effect on the organic waste gas.

Detailed implementation manner

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0039] As Figures 1 to 9 shown, in the embodiment of the present invention, a device for preparing ABS waterborne acrylic paint includes a preparation tank 1. A stirring member 2 is installed inside the preparation tank 1. A stirring mechanism 3 is installed at the top of the stirring member 2. The stirring mechanism 3 is arranged on the top of the preparation tank 1. A filtering assembly is arranged on one side of the preparation tank 1;

[0040] The filtering assembly includes a treatment box 5 arranged on one side of the preparation tank 1. The inner cavities of the preparation tank 1 and the treatment box 5 are communicated through a guiding pipe 4. A filter plate 6 is installed inside the treatment box 5. The filter plate 6 is rotatably connected to the treatment box 5 through a rotating assembly. A cleaning assembly is arranged at the bottom of the filter plate 6;

[0041] An exhaust fan 7 is installed inside the treatment box 5. A rotating ring 8 is fixedly installed on the outer wall of the exhaust fan 7. The exhaust fan 7 is arranged on one side of the filter plate 6.

[0042] Existing: CN218516459U discloses a paint preparation device. The preparation tank 1, the stirring member 2 and the stirring mechanism 3 proposed in the present application document are disclosed in this patent. These technical means will not be elaborated one by one here;

[0043] The exhaust fan 7 is driven by a built-in motor;

[0044] During operation, the exhaust fan 7 is started to generate negative pressure in the treatment box 5 and connect the guiding pipe 4 to introduce the gas in the preparation tank 1 into the treatment box 5. After being filtered by the filter plate 6, it is discharged from the device, preventing the organic waste gas generated during the preparation of ABS waterborne acrylic paint from being directly discharged, which affects the physical and mental health of the staff and causes air pollution, and optimizing the production environment.

[0045] When the air pressure inside the device in the preparation tank 1 is weak, the exhaust fan 7 may not be started, and the air pressure itself flows into the treatment tank 5 for filtration.

[0046] As Figures 1 to 8 shown, the rotating assembly includes a first rotating shaft 15 rotatably installed inside the treatment tank 5, and the filter plates 6 are evenly installed in an annular array on the inner wall of the first rotating shaft 15;

[0047] One side of the rotating ring 8 is meshed with a first gear 9. A first reciprocating lead screw 10 is fixedly installed on the inner wall of the first gear 9. A moving plate 11 is threadedly connected to the outer wall of the first reciprocating lead screw 10. A tooth block seat 12 is fixedly installed on one side of the moving plate 11. Tooth blocks 13 are evenly installed inside the tooth block seat 12. The top of the tooth blocks 13 is meshed with a second gear 14, and the second gear 14 is fixedly installed on the outer wall of the first rotating shaft 15.

[0048] Four filter plates 6 are provided, and the number of tooth blocks 13 meshed with them is set to one-fourth of the outer wall of the second gear 14;

[0049] During operation, the rotation of the exhaust fan 7 drives the rotation of the rotating ring 8. The rotation of the rotating ring 8 drives the rotation of the first gear 9. The rotation of the first gear 9 drives the rotation of the first reciprocating lead screw 10. The rotation of the first reciprocating lead screw 10 drives the reciprocating movement of the moving plate 11. The movement of the moving plate 11 drives the movement of the tooth block seat 12. The movement of the tooth block seat 12 drives the movement of the tooth blocks 13. When the tooth blocks 13 move, they drive the rotation of the second gear 14. The rotation of the second gear 14 drives the rotation of the first rotating shaft 15. The rotation of the first rotating shaft 15 drives the rotation of the filter plates 6, enabling each area to have the opportunity to come into contact with the waste gas, avoiding the situation of excessive local filtration load, and thus improving the overall filtration efficiency.

[0050] As Figures 1 to 9 shown, the cleaning assembly includes a brush plate 16 arranged at the bottom of the filter plate 6. Sliders 17 are installed on both sides of the bottom of the brush plate 16. A limiting shaft 18 and a second reciprocating lead screw 19 are respectively embedded in the inner walls of the two sliders 17. The limiting shaft 18 is slidably connected to the slider 17, and the second reciprocating lead screw 19 is meshed with the slider 17. One end of the second reciprocating lead screw 19 is fixedly installed with a third gear 20.

[0051] Two groups of tooth blocks 13 are provided. One group of tooth blocks 13 is meshed with the second gear 14, and the other group of tooth blocks 13 is meshed with the third gear 20;

[0052] When another set of tooth blocks 13 mesh with the third gear 20, it drives the third gear 20 to rotate. The rotation of the third gear 20 drives the rotation of the second reciprocating lead screw 19. The rotation of the second reciprocating lead screw 19 drives the slider 17 to move reciprocally. The movement of the slider 17 drives the movement of the brush plate 16, causing the brush plate 16 to move reciprocally once at the bottom of the filter plate 6 for cleaning, removing the particulate matter blocked in the pores, reducing the frequency of manual maintenance, and ensuring the filtering effect of the organic waste gas.

[0053] The filter plate 6 rotates towards the side of the exhaust fan 7. When the left side of the filter plate 6 rotates to the top of the brush plate 16 after filtering the organic waste gas, its surface is cleaned by the brush plate 16.

[0054] As Figures 1 to 4 shown, a slag collection box 27 is arranged below the brush plate 16, and the slag collection box 27 is slidably installed inside the treatment box 5.

[0055] The slag collection box 27 receives the impurities brushed off, facilitating maintenance.

[0056] As Figure 7 and Figure 8 shown, each tooth block 13 is rotatably installed inside the tooth block seat 12 through a second rotating shaft 22, and a torsion spring 21 is installed on the outer wall of each second rotating shaft 22.

[0057] A chute for the rotation of the tooth block 13 is opened inside the tooth block seat 12, and one side of the tooth block 13 is inclined.

[0058] When the inclined surface of the tooth block 13 contacts the second gear 14 or the third gear 20, it is forced to slide into the tooth block seat 12. At this time, the torsion spring 21 deforms to store elastic potential energy. When the tooth block 13 separates from the second gear 14 or the third gear 20, the elastic potential energy is released by the torsion spring 21 to reset.

[0059] So that one reciprocating movement of the tooth block seat 12 only drives the second gear 14 or the third gear 20 to rotate once, making the second gear 14 or the second reciprocating lead screw 19 rotate unidirectionally.

[0060] As Figures 4 to 7 shown, there are two tooth block seats 12, and the tooth blocks 13 installed inside the two tooth block seats 12 are symmetrically distributed.

[0061] When the tooth block seat 12 moves towards the side of the second gear 14, the second gear 14 rotates to drive the filter plate 6 to rotate. At this time, the third gear 20 does not rotate.

[0062] When the tooth block seat 12 moves towards the side away from the second gear 14, the second gear 14 does not rotate and the third gear 20 rotates, making the two alternate intermittently to prevent movement interference.

[0063] As Figure 7 andFigure 8 As shown, both ends of the brush plate 16 are fixedly connected with connecting plates 25. The connecting plates 25 are slidably installed inside the sliders 17, and a spring 26 is arranged between the connecting plates 25 and the sliders 17.

[0064] As Figure 5 、 Figure 6 and Figure 7 shown, a convex block 24 is arranged on one side of the brush plate 16. The convex block 24 is fixedly installed on the side wall of the rotating disk 23, and the rotating disk 23 is fixedly installed on the outer wall of the first rotating shaft 15.

[0065] When the first rotating shaft 15 rotates, it drives the rotating disk 23 to rotate. The rotation of the rotating disk 23 drives the rotation of the convex block 24. When the convex block 24 rotates to the lower part and contacts the brush plate 16, it drives the brush plate 16 to move to one side. When the brush plate 16 moves, it drives the connecting plate 25 to slide inside the slider 17. At the same time, the spring 26 is stressed and stores elastic potential energy. When the convex block 24 rotates and separates from the brush plate 16, the elastic potential energy is released through the spring 26 to make the connecting plate 25 move back to its original position, so that the brush plate 16 vibrates reciprocally, which helps to shake off the impurities inside the bristles at the top of the brush plate 16.

[0066] As Figure 9 shown, through holes 28 are formed in the inner wall of the brush plate 16, and the through holes 28 are uniformly arranged.

[0067] A preparation method of an ABS waterborne acrylic paint preparation device includes the following steps:

[0068] S1: When preparing the ABS waterborne acrylic paint, start the exhaust fan 7 to generate negative pressure in the treatment tank 5 and connect the guide pipe 4 to introduce the gas in the preparation tank 1 into the treatment tank 5 for filtration through the filter plate 6;

[0069] S2: The rotation of the exhaust fan 7 drives the rotation of the rotating ring 8. The rotation of the rotating ring 8 drives the rotation of the first gear 9. The rotation of the first gear 9 drives the rotation of the first reciprocating lead screw 10. The rotation of the first reciprocating lead screw 10 drives the moving plate 11 to reciprocate. The movement of the moving plate 11 drives the movement of the tooth block seat 12. The movement of the tooth block seat 12 drives the movement of the two groups of tooth blocks 13. When one group of tooth blocks 13 moves, it drives the second gear 14 to rotate. The rotation of the second gear 14 drives the rotation of the first rotating shaft 15. The rotation of the first rotating shaft 15 drives the rotation of the filter plate 6, so that each area has the opportunity to contact the waste gas. When one group of tooth blocks 13 returns to its original position, it is forced to slide into the tooth block seat 12, and the second gear 14 does not rotate;

[0070] S3: When the other set of tooth blocks 13 are reset and engage with the third gear 20, the third gear 20 is driven to rotate. The rotation of the third gear 20 drives the rotation of the second reciprocating lead screw 19. The rotation of the second reciprocating lead screw 19 drives the slider 17 to reciprocate. The movement of the slider 17 drives the movement of the brush plate 16, causing the brush plate 16 to reciprocate once at the bottom of the filter plate 6 for cleaning;

[0071] S4: When the first rotating shaft 15 rotates, it drives the rotating disk 23 to rotate. The rotation of the rotating disk 23 drives the rotation of the convex block 24. When the convex block 24 rotates to the lower side and contacts the brush plate 16, it drives the brush plate 16 to move to one side. When the brush plate 16 moves, it drives the connecting plate 25 to slide inside the slider 17. At the same time, the spring 26 is stressed and stores elastic potential energy. When the convex block 24 rotates and separates from the brush plate 16, the elastic potential energy is released by the spring 26 to make the connecting plate 25 move back to its original position, thereby causing the brush plate 16 to vibrate reciprocally, which helps to shake off the impurities inside the bristles at the top of the brush plate 16;

[0072] S5: Finally, the organic waste gas filtered by the filter plate 6 is discharged from the device.

[0073] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.

When the convex block (24) rotates to the lower part and contacts the brush plate (16), it drives the brush plate (16) to move to one side. When the brush plate (16) moves, it drives the connecting plate (25) to slide inside the slider (17), and at the same time the spring (26) is stressed to store elastic potential energy. When the convex block (24) rotates and separates from the brush plate (16), the elastic potential energy is released through the spring (26) to make the connecting plate (25) move back to its original position, so that the brush plate (16) reciprocates and vibrates, which helps to shake off the impurities inside the bristles at the top of the brush plate (16); S5: Finally, the organic waste gas filtered by the filter plate (6) is discharged from the device.
