Description

Technical Field

[0001] The utility model relates to the technical field of coating production equipment, in particular to acrylic acid powder coating production equipment. Background Art

[0002] Acrylic acid is an important chemical raw material; this product and its esters can be used as monomers of polymers; in addition, it can also be used as raw materials for adhesives, coatings, resins, etc. The resins synthesized from this product can be used in pharmaceutical, leather, textile, papermaking, chemical fiber, rubber, packaging materials, water treatment, oil extraction and other industries. In the production process of acrylic paint, acrylic powder needs to be added to the paint for mixing, but acrylic powder is easy to form lumps when it is damp, and it is difficult to dissolve when mixed, which reduces the quality of the paint. Therefore, it is necessary to crush the agglomerated acrylic powder into powder. However, after the existing crushing device crushes the agglomerated powder, there will still be a lot of large particles. After screening through the screen, the staff needs to crush the remaining agglomerates again, which reduces the efficiency of powder production and wastes the time and energy of the staff.

[0027] See also Figure 1-4, including a collecting box 1, a fixed plate 8, fixed inside the collecting box 1, and a through hole is opened at the center; a screen 9, fixed on the top of the fixed plate 8, the screen 9 is in a truncated cone shape, and the outer edge of the bottom of the screen 9 is fixed to the edge of the through hole of the fixed plate 8. When the powdered paint falls on the surface of the screen 9, smaller particles can directly pass through the screen 9 and fall below the screen 9, and the screen 9 is designed as a slope. When a large amount of powdered paint is stacked at one time, the paint can slide along the slope of the screen 9 to disperse the amount stacked together, which is convenient for powder screening; a baffle 10, fixed on the surface of the fixed plate 8 The baffle 10 can enclose the bottom of the screen 9 to prevent larger particles that have not passed through the screen 9 from sliding directly to the surface of the fixed plate 8; the bevel gear 11 is fixed on the outer ring surface of the baffle 10; the rolling roller 12 is installed on the surface of the screen 9, and the unscreened powder coating remaining on the surface of the screen 9 can be rolled by the rolling roller 12 to break larger particles of powder coating, making it easier for the powder to pass through the screen 9; the transmission device is installed at both ends of the rolling roller 12, and the rolling roller 12 is made to move in a circle on the surface of the screen 9 through the transmission device. The transmission device includes a gear shaft ring 13, a connecting plate 14, and a second motor 15. The gear shaft ring 13 is sleeved on one end of the rolling roller 12 close to the baffle 10, and the gear shaft ring 13 is meshed with the bevel gear 11. The connecting plate 14 is installed at the end of the rolling roller 12 away from the gear shaft ring 13. The connecting plate 14 has a through hole corresponding to the position of the central axis of the rolling roller 12, and the central axis of the rolling roller 12 passes through the through hole. The second motor 15 is installed below the screen 9. The screen 9 has a movable hole corresponding to the position of the second motor 15. The transmission end of the second motor 15 passes through the movable hole and is fixed to the bottom of the connecting plate 14. A support frame is provided at the bottom of the second motor 15. The support frame is fixed to the inner wall of the collecting box 1 through a support rod. Machine 2 15 realizes support. When the large particles of powder coating left on the surface of the screen 9 are crushed, the starting motor 2 15 drives the connecting plate 14 to rotate. When the connecting plate 14 rotates, it drives the crushing roller 12 to make a circular motion on the surface of the screen 9. When the crushing roller 12 moves, the gear shaft ring 13 sleeved on the end of the crushing roller 12 meshes with the bevel gear 11, thereby starting to rotate on its own. When the crushing roller 12 rotates on its own, it crushes the powder coating intercepted by the baffle 10 on the surface of the screen 9, which facilitates the powder to pass through the screen 9 and improves the screening effect of the powder coating. There is no need for the staff to process and crush the large particles of powder coating multiple times, thereby improving the production efficiency of powder crushing and reducing the difficulty of operation for the staff.

[0028] A feed box 2 is installed on the top of the collection box 1, and a feed opening 6 is provided at the bottom of the feed box 2. A crushing roller 3 is installed inside the feed box 2, and a guide plate 4 is provided above the crushing roller 3. A motor 5 is installed on the outer wall of the feed box 2 at the position corresponding to the crushing roller 3. The acrylic powder coating is fed into the feed box 2 through the feed opening of the feed box 2. The powder coating falls between the two crushing rollers 3 under the guidance of the guide plate 4. The crushing roller 3 is driven to rotate by the motor 5. When the crushing roller 3 rotates, the powder coating is squeezed to achieve the first crushing of the powder coating. A guide plate 27 is installed below the motor 5. The bottom of the guide plate 27 is directly opposite to the top of one side of the screen 9. The powder coating crushed by the crushing roller 3 is guided by the guide plate 27 so that the powder coating falls on the surface of the screen 9 for screening. The smaller particles falling on the surface of the screen 9 can directly pass through the mesh of the screen 9, and the larger particles remain on the surface of the screen 9 and are crushed by the rolling roller 12 for secondary crushing.

[0029] A connecting frame 16 is installed on one side of the rolling roller 12, and the connecting frame 16 is sleeved on the central axis at both ends of the rolling roller 12. A brush 17 is installed at the bottom of the connecting frame 16, and the bottom of the brush 17 is in contact with the surface of the screen 9. When the rolling roller 12 makes a circular motion on the surface of the screen 9, the brush 17 moves on the surface of the screen 9 together with the rolling roller 12 through the connecting frame 16. When the brush 17 moves, the powder on the surface of the screen 9 that has been rolled by the rolling roller 12 can be moved, so that the crushed powder falls through the mesh of the screen 9 during the movement, and when the rolling roller 12 rolls the large particles of paint on the surface of the screen 9, some of the paint will be directly stuffed into the mesh of the screen 9. When the brush 17 passes by, the paint in the mesh can be cleaned to reduce the mesh blockage problem of the screen 9.

[0030] A guide plate 3 18 is fixed below the screen 9 , and the powder sieved by the screen 9 is collected and guided by the guide plate 3 18 , and the powder is sent out of the collection box 1 .

[0031] Working principle: when producing acrylic powder coating, the acrylic powder is first screened to facilitate the subsequent uniform mixing of the powder and the coating. During the screening process, the powder will be damp and agglomerated, which will affect the screening of the powder. At this time, the powder can be crushed and screened by this equipment. First, the acrylic powder is fed into the feed box 2 from the feed port of the feed box 2. The powder falls to the surface of the crushing roller 3 through the guidance of the guide plate 4. The crushing roller 3 is driven by the motor 5 to perform primary crushing on the powder and crush the agglomerated powder. The crushed powder falls to the surface of the screen 9 through the guide plate 7. There are still larger particles in the crushed powder that have not been completely crushed. The larger particles pass through the screen 9. The powder is screened and retained on the surface of the screen 9. The motor 15 drives the rolling roller 12 to make a circular motion on the surface of the screen 9, so that the rolling roller 12 rotates along the bevel gear 11, thereby rolling the powder on the surface of the screen 9, and achieving comprehensive crushing of the powder. When the rolling roller 12 rolls, a part of the powder will be stuffed into the mesh of the screen 9, causing the screen 9 to be blocked. The surface of the screen 9 can be cleaned by the brush 17 arranged on the side of the rolling roller 12. When the brush 17 moves with the rolling roller 12, it can push the powder rolled by the rolling roller 12, so that the powder falls from a suitable position to the bottom of the screen 9, and the bottom of the brush 17 can clean the mesh on the surface of the screen 9 to reduce the blockage of the mesh of the screen 9.
