Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, in particular to a multi-stage filtering device for primer processing. Background Art

[0002] Paint is mainly applied on the surface of objects to protect or decorate them. When using paint, in order to increase the firmness between the paint and the object, a layer of primer is usually applied before coating to prevent the paint from falling off due to long-term use. White primer requires filtering equipment during production and processing.

[0003] According to a multi-stage filter for white primer processing disclosed (publication number: CN218687192U), the above application is provided with a rotating disc, a first filter screen, a feed port, a second filter screen, a movable plate and a second drive motor. When in use, the material passes through the first filter screen and the second filter screen in sequence, and the material is subjected to a secondary filtration treatment. At the same time, the second drive motor is started to drive the rotating disc to start rotating motion, so that the connecting rod starts to move left and right at a high frequency, and the movable plate starts to vibrate at a high frequency, which speeds up the speed of the material passing through the second filter screen, thereby improving the filtering effect. Start the first drive motor, first drive the movable shaft to rotate, and then the bulk plate and scraper to rotate. Use the scraper to break up the larger block materials in the raw materials to facilitate filtering. The scraper can sweep the materials blocked at the first filter screen to prevent the materials from being blocked on the mesh. Start the rotating motor to drive the small gear to rotate. Since the small gear and the large gear are connected by a connecting belt, the large gear is driven to rotate, and the connecting shaft and the stirring blades start to rotate, stirring the internal materials and evenly stirring the materials settled at the bottom, reducing the unevenness between the materials and ensuring the processing quality.

[0004] In order to improve the filtering effect, break up the materials and clear the mesh, and evenly stir the materials, the above technical solution adopts three sets of motors for driving. The three sets of motors installed on the main body of the equipment not only increase the manufacturing cost of the equipment, but also consume a lot of electricity resources when the three sets of motors run at the same time, which is not conducive to saving electricity resources. In turn, it will lead to an increase in the production cost of the coating and affect the long-term development of the enterprise. Utility Model Content

When the paint is filtered, the motor 6 is started to drive the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, the scraper 8 will be driven to fit on the upper surface of the coarse screen plate 2 to rotate. At this time, the scraper 8 can be used to break up the larger particles in the raw material to prevent the particles from clogging the coarse screen plate 2, so that the coarse screen plate 2 can fully filter the paint. The outer wall of the rotating shaft 7 is fixedly mounted with a bulk plate 9, and the filter box 1 is provided with a driving mechanism 10. By setting the driving mechanism 10, not only the fine screen plate 3 can be driven to shake back and forth, but also the rotating rod 4 can be driven to rotate back and forth. The interior of the filter box 1 is provided with a shoveling bottom mechanism 11 to prevent the paint from sinking to the bottom. By setting the bottom shoveling bottom mechanism 11, the paint deposited at the bottom of the filter box 1 can be shoveled up to prevent the paint from sinking to the bottom, so that the stirring rod 5 can evenly mix the paint, further improving the mixing effect of the paint.

[0024] The driving mechanism 10 includes an eccentric wheel 101, a spiral groove 102, an L rod 103, a rectangular frame 104, and a sliding rod 105; the eccentric wheel 101 is fixedly mounted on the outer wall of the rotating shaft 7, the L rod 103 is slidably connected to the inner wall of the filter box 1, and the L rod 103 passes through the filter box 1, one end of the L rod 103 is fixedly mounted with a rectangular frame 104, the outer wall of the eccentric wheel 101 is attached to the inner wall of the rectangular frame 104, and the rotation of the rotating shaft 7 will drive the eccentric wheel 101 to rotate synchronously.

When the L rod 103 slides back and forth, it will drive the fine screen plate 3 to slide back and forth synchronously on the inner wall of the filter box 1, so that the fine screen plate 3 can shake back and forth quickly, thereby speeding up the speed of the paint passing through the fine screen plate 3 and improving the filtering effect. A spiral groove 102 is provided on the rotating rod 4, and the outer wall of the slide rod 105 is attached to the inner wall of the spiral groove 102. During the reciprocating sliding of the L rod 103, the slide rod 105 is driven to move back and forth on the inner wall of the spiral groove 102.

When the eccentric disk 115 pushes and pulls the side plate 112 back and forth, the side plate 112 will swing back and forth and drive the rotating ring 111 to rotate back and forth. The bottom of the side plate 112 is fixedly installed with a shovel plate 114, which fits the bottom of the inner wall of the filter box 1, and the side plate 112 swings back and forth. At the same time, the shovel plate 114 will be driven to move back and forth in contact with the bottom of the inner wall of the filter box 1. At this time, the shovel plate 114 can be used to shovel up the paint deposited on the bottom of the filter box 1 to prevent the paint from sinking to the bottom, so that the stirring rod 5 can evenly mix the paint. The outer wall of the rotating rod 4 is fixedly installed with an eccentric disk 115, and the outer wall of the eccentric disk 115 is in contact with the inner wall of the limiting groove 113.

[0026] Working principle: The coarse screen plate 2 can be used to filter the paint preliminarily, and the fine screen plate 3 can be used to filter the paint for the second time. The filtered paint is temporarily stored in the interior of the filter box 1. While the paint is being filtered, the motor 6 is started to drive the rotating shaft 7 to rotate. While the rotating shaft 7 is rotating, it will drive the scraper 8 to rotate in contact with the upper surface of the coarse screen plate 2. At this time, the scraper 8 can be used to break up the larger particles in the raw material to prevent the particles from clogging the coarse screen plate 2, so that the coarse screen plate 2 can fully filter the paint. At the same time, the rotating shaft 7 will drive the eccentric wheel 101 to rotate synchronously. While the eccentric wheel 101 rotates, it will move back and forth in contact with the inner wall of the rectangular frame 104 and push and pull the rectangular frame 104 back and forth, so that the rectangular frame 104 drives the L rod 10 3 slides back and forth on the inner wall of the filter box 1. When the L rod 103 slides back and forth, it will drive the fine screen plate 3 to slide back and forth on the inner wall of the filter box 1 synchronously, so that the fine screen plate 3 shakes back and forth quickly, thereby accelerating the speed of the paint passing through the fine screen plate 3 and improving the filtering effect. At the same time, the reciprocating sliding of the L rod 103 will drive the sliding rod 105 to move back and forth in contact with the inner wall of the spiral groove 102. At this time, the sliding rod 105 will reciprocate and squeeze the spiral groove 102, so that the rotating rod 4 can rotate back and forth on the inner wall of the filter box 1. The reciprocating rotation of the rotating rod 4 and the stirring rod 5 can stir the paint after filtering inside the filter box 1, so that the paint can be evenly mixed together, ensuring the processing quality of the paint.

[0027] When the rotating rod 4 rotates, it drives the eccentric disk 115 to rotate synchronously. At this time, the eccentric disk 115 will fit the inner wall of the limiting groove 113 and move back and forth and push and pull the side plate 112 back and forth, so that the side plate 112 swings back and forth and drives the rotating ring 111 to rotate back and forth. When the side plate 112 swings back and forth, it will drive the shovel plate 114 to fit the bottom of the inner wall of the filter box 1 and move back and forth. At this time, the shovel plate 114 can be used to shovel up the paint deposited on the bottom of the filter box 1 to prevent the paint from sinking to the bottom, so that the stirring rod 5 can mix the paint evenly, further improving the mixing effect of the paint, thereby further improving the production quality of the paint.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
