Description

Technical Field

[0001] The utility model relates to the technical field of powder coatings, in particular to an integrated device for pressing and crushing powder coatings. Background Art

[0002] During the processing of powder coatings, some caked or large flaky coatings are generally crushed into coating particles. However, in traditional crushing methods, the flaky coatings are generally poured into a crushing cylinder, and the caked powder is broken by a continuously rotating cutting blade. However, since the cutting blade only rotates and cuts singly, it is not convenient to cut the powder at different heights in the crushing cylinder, resulting in incomplete crushing. In addition, during the crushing process, the coatings are easily adhered to the inner wall of the crushing cylinder and are not easy to remove in time, causing the loss of coating powder. Therefore, those skilled in the art provide an integrated device for pressing and crushing powder coatings to solve the problems raised in the above background art. Content of the Utility Model

[0020] In the present utility model, the jacking assembly includes an inclined surface disk 16 and a positioning rod 15. Limiting strips 18 are fixedly mounted on both sides of a transmission shaft 14 by bolts. A sleeve 17 penetrates through and is vertically slidably connected to the limiting strips 18. The inclined surface disk 16 is sleeved on the two limiting strips 18, and the inclined surface disk 16 is fixed to the top of the sleeve 17. A positioning rod 15 is fixedly mounted on the bottom of a cover plate 2 by bolts, and the bottom end of the positioning rod 15 is in contact with the inclined surface disk 16. A tension spring 19 is welded to the outer wall of the bottom end of the transmission shaft 14, and the top end of the tension spring 19 is in contact with the bottom end of the sleeve 17. When the sleeve 17 rotates, the inclined surface disk 16 rotates. During the rotation of the inclined surface disk 16, the positioning rod 15 presses against the inclined surface disk 16. At this time, the inclined surface disk 16 drives the sleeve 17 to move downward along the limiting strips 18, and the tension spring 19 is stressed and contracts. When the lowest end of the inclined surface disk 16 rotates below the positioning rod 15, the tension spring 19 rebounds and resets, and the sleeve 17 moves upward. By cycling in this way, the sleeve 17 can move up and down along the limiting strips 18 during rotation, so that the slicing blade 13 can cut and crush coatings at different heights.

[0021] In the present utility model, the vibration assembly is a plurality of rubber balls 9. Connecting plates 10 are provided on the outer walls of both sides of a cylinder body 1.

The push rod 8 penetrates through and is slidably connected in the positioning sleeve 6. One end of the push rod 8 is in contact with the cam 5, and the other end of the push rod 8 is fixed to the connecting plate 10. A spring 7 is sleeved on the circumferential outer wall of the push rod 8, and both ends of the spring 7 are fixed to the push rod 8 and the positioning sleeve 6 respectively. During the rotation of the transmission shaft 14, the cam 5 is also driven to rotate. When the cam 5 rotates, it presses against the push rod 8. Subsequently, the push rod 8 moves along the positioning sleeve 6, and the spring 7 is stressed and contracts. The movement of the push rod 8 causes the connecting plate 10 to drive the rubber balls 9 to move outward and separate from the cylinder body 1. When the cam 5 rotates away from the push rod 8, the spring 7 rebounds and resets, causing the push rod 8 to drive the connecting plate 10 to reset. The rubber balls 9 reset and impact the cylinder body 1, and the cylinder body 1 generates vibrations when being impacted, shaking off the coatings adhering to the inner wall of the cylinder body 1.

[0022] In the present utility model, a filter disk 20 is fixedly mounted on the inner wall of the cylinder body 1 near the bottom by bolts, and the cut and crushed coatings are filtered through the filter disk 20.

[0023] In the utility model, a scraper bar 12 is fixed to the bottom end of a transmission shaft 14 by bolts, and the bottom of the scraper bar 12 is in contact with the filter disc 20. A plurality of cone thorns 11 are welded on both sides of the scraper bar 12. The scraper bar 12 is driven to rotate during the rotation of the transmission shaft 14. The scraper bar 12 rotates along the filter disc 20 to move the paint remaining on the filter disc 20 to prevent the paint from clogging the filter disc 20. The rotation of the scraper bar 12 drives the plurality of cone thorns 11 to rotate, and the cone thorns 11 puncture the paint to achieve further crushing.

[0024] In the utility model, the bottom of the cylinder 1 is fixedly connected with a material guide pipe 21 , and the valve of the material guide pipe 21 is opened, and the filtered paint is discharged from the material guide pipe 21 .

[0025] Working principle: when it is necessary to crush the block-shaped paint, pour the paint into the cylinder 1, start the motor 4, the motor 4 rotates to rotate the transmission shaft 14, the transmission shaft 14 rotates to make the limit bar 18 drive the sleeve 17 to rotate, the sleeve 17 rotates to make multiple rotary slices 13 rotate, the rotary slices 13 rotate to rotary cut and crush the paint, and the sleeve 17 rotates to make the inclined disk 16 rotate, during the rotation of the inclined disk 16, the positioning rod 15 squeezes the inclined disk 16, at this time the inclined disk 16 drives the sleeve 17 to move downward along the limit bar 18, the tension spring 19 is forced to shrink, and when the lowest end of the inclined disk 16 rotates to the bottom of the positioning rod 15, the tension spring 19 rebounds and resets, and the sleeve 17 moves upward, and this cycle can make the sleeve 17 move up and down along the limit bar 18 during the rotation process, so that the rotary slice 13 can cut and crush paints of different heights;

[0026] The cut and crushed paint is filtered through the filter disc 20 and then discharged from the guide pipe 21. The drive shaft 14 rotates to drive the scraper bar 12 to rotate. The scraper bar 12 rotates along the filter disc 20 to move the paint remaining on the filter disc 20 to prevent the paint from clogging the filter disc 20. The rotation of the scraper bar 12 drives the multiple cone thorns 11 to rotate, and the cone thorns 11 puncture the paint to achieve further crushing.

[0027] During the rotation of the transmission shaft 14, the cam 5 is also driven to rotate. The rotation of the cam 5 squeezes the push rod 8, and then the push rod 8 moves along the positioning sleeve 6. The spring 7 is forced to shrink, and the push rod 8 moves to make the connecting plate 10 drive the rubber ball 9 to move outward and disengage from the cylinder 1. When the cam 5 rotates to disengage from the push rod 8, the spring 7 rebounds and resets to make the push rod 8 drive the connecting plate 10 to reset. The rubber ball 9 resets and hits the cylinder 1. The cylinder 1 is vibrated by the impact, and the paint adhering to the inner wall of the cylinder 1 is shaken off and cleaned in time.
