Description

Technical Field

[0001] The utility model relates to the technical field of dust recovery, and in particular to a dust recovery device for wood grain transfer coating. Background Art

[0002] The plastic spraying dust generated during the production of wood grain transfer paint can be treated through specific recycling equipment, which can effectively reduce dust emissions and protect the environment from pollution. However, how to prevent dust from adhering to the inside of the recycling equipment and how to improve the recycling efficiency of wood grain transfer paint dust are currently urgent problems to be solved.

[0003] After searching, the announcement number CN214133120U discloses a dust recovery device for the production of glue-pasted thermal transfer wood grain polyester powder coatings, including a device shell, a cover plate is provided above the device shell, and the left and right sides of the upper surface of the cover plate are fixedly connected to telescopic motors, and the bottom surfaces of the two telescopic motors are respectively fixedly connected to telescopic rods. The suction fan and the telescopic motor are started, and the dust can be collected into the device shell by the action of the suction fan. The telescopic motor is started to drive the telescopic rod to move up and down, and the upward and downward movement of the telescopic rod drives the horizontal plate to move up and down in the placement groove, and the upward and downward movement of the horizontal plate drives the filter body to move up and down. The upward and downward movement of the horizontal plate squeezes the spring, causing the filter body to vibrate, thereby separating the dust from impurities.

[0004] The above-mentioned dust recovery device for the production of glue-pasting thermal transfer wood grain polyester powder coating is to separate the dust and impurities by vibrating the filter body so that the dust on the upper part of the filter body falls under the action of vibration. However, in this design, the dust falls simply by its own gravity after being screened by the screen.

At the same time, during the vibration of the screen body, this design will cause the dust to be affected by the vibration and diffuse inside the shell and adhere to the inner wall of the shell. This design will also make it impossible to effectively recover the dust attached to the shell. Utility Model Content

[0032] The working principle and use process of this utility model are as follows:

[0033] After the staff can put the screened raw materials into the screening barrel 1 through the feed port 12, they can first use the external buckle plate to complete the sealing cover of the feed port 12. At this time, the raw materials will fall above the screening mesh 62. At this time, the forward and reverse motors 31 are started so that the output ends of the forward and reverse motors 31 drive the threaded rod 32 to rotate, thereby causing the slide 41 threadedly connected to the outside of the threaded rod 32 to move synchronously until the slide 41 drives the mounting sleeve 42 to move up to the bottom of the screening assembly 6. Then the driving motor 44 can be started so that the output end of the driving motor 44 drives the rotating shaft 441 and the fan blades 442 to rotate and form suction. At this time, the dust that has been screened and fallen will be sucked into the mounting sleeve 42 through the inlet hole 431. After the dust is sucked into the mounting sleeve 42 from the inlet hole 431, the dust will continue to circulate in the connecting hose 22 through the mounting sleeve 42 until it is discharged into the recovery box 21. The thickness of the dust accumulated in the recovery box 21 can be observed through the glass observation window 211. When the dust is in the recovery box When the accumulation thickness in the box 21 reaches a certain amount, the cover plate 23 can be removed to complete the dust collection work, and the present design can start the forward and reverse motor 31 to drive the threaded rod 32 to rotate forward and reverse, thereby enabling the slide 41 to drive the mounting sleeve 42 and the scraper assembly 5 fixedly installed on the upper layer of the mounting sleeve 42 to move up and down. At this time, the lower annular plate 53 will synchronously move up and down and repeatedly push the screening plate 61 upward through the top block 54. At this time, the screening plate 61 slidably connected to the outer side of the inner column 63 will move up and down rapidly under the action of the top block 54 and the spring ring 631, thereby forming a vibration effect to complete the screening work. In particular, when the screening work is completed, the forward and reverse motor 31 can be started to drive the threaded rod 32 to reverse, thereby causing the annular plate 53 and the annular scraper 531 to move down, thereby enabling the side support rod 52 to drive the annular plate 53 and cooperate with the annular scraper 531 on the outer side of the annular plate 53 to scrape the dust attached to the inner wall of the screening barrel 1.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
