Technical Field

[0001] The utility model relates to the field of resin particle material screening devices, in particular to a water-absorbing resin particle material classification screening device. Background Art

[0002] Resin usually refers to an organic polymer that softens or melts when heated, tends to flow under the action of external force when softened, is solid, semi-solid, or sometimes liquid at room temperature. Any polymer compound that can be used as a raw material for plastic product processing is called a resin.

[0003] The particle size of the resin will affect the uniformity of mixing and plasticization. Large resin particle size is prone to uneven mixing and difficult or incomplete plasticization. Therefore, it is necessary to screen the oversized particles in the resin. For example, the prior art represented by CN220719971U has a structural defect: the resin particles cannot be screened multiple times, resulting in reduced screening efficiency.

When the first rotating shaft 5 rotates, it drives the first connecting rod 6 to rotate. When the first connecting rod 6 rotates, the first screening frame 7 is driven to reciprocate through the second connecting rod 8. The reciprocating movement of the first screening frame 7 pushes the resin particles inside it back and forth, which is conducive to the screening of the resin particles. Then, the large particles in the material remain in the first screening frame 7, and the resin particles that meet the specifications pass through the first screening frame 7 and then enter the second screening frame 11 along the unloading frame 9.

[0023] In this embodiment: when the worm 4 rotates, it will drive the worm wheel 13 and the second rotating shaft 12 to rotate. When the worm wheel 13 rotates, it will drive the second screening frame 11 to swing back and forth through the fourth connecting rod 14. At the same time, when the second rotating shaft 12 rotates, it will drive the first sprocket to rotate. Then the first sprocket drives the second sprocket and the third rotating shaft 16 to rotate through the chain. When the third rotating shaft 16 rotates, it drives the fifth connecting rod 17 to rotate. When the fifth connecting rod 17 rotates, it drives the push plate 19 to move through the sixth connecting rod 20. The push plate 19 reciprocates along the slide groove 18 to stir the resin particles in the second screening frame 11. Through the reciprocating swing of the second screening frame 11 and the reciprocating movement of the push plate 19, the resin particles that meet the requirements can quickly pass through the second screening frame 11, and those that do not meet the requirements will remain in the second screening frame 11.

[0024] Working principle: Pour the resin particles to be screened into the first screening frame 7, and then start the motor 3 to drive the first pulley and the worm 4 to rotate. When the first pulley rotates, the second pulley is driven to rotate through the belt, and then the first rotating shaft 5 is driven to rotate through the second pulley. When the first rotating shaft 5 rotates, it drives the first connecting rod 6 to rotate. When the first connecting rod 6 rotates, it drives the first screening frame 7 to reciprocate through the second connecting rod 8. The reciprocating movement of the first screening frame 7 pushes the material inside it, which is conducive to the screening of resin particles. Then, the large particles in the material remain in the first screening frame 7, and the resin particles that meet the specifications pass through the first screening frame 7 and then enter the second screening frame 11 along the unloading frame 9.

[0025] When the worm 4 rotates, it will drive the worm wheel 13 and the second rotating shaft 12 to rotate. When the worm wheel 13 rotates, it will drive the second screening frame 11 to swing back and forth through the fourth connecting rod 14. At the same time, when the second rotating shaft 12 rotates, it will drive the first sprocket to rotate. Then the first sprocket drives the second sprocket and the third rotating shaft 16 to rotate through the chain. When the third rotating shaft 16 rotates, it drives the fifth connecting rod 17 to rotate. When the fifth connecting rod 17 rotates, it drives the push plate 19 to move through the sixth connecting rod 20. The push plate 19 reciprocates along the slide groove 18 to stir the resin particles in the second screening frame 11. Through the reciprocating swing of the second screening frame 11 and the reciprocating movement of the push plate 19, the resin particles that meet the requirements can quickly pass through the second screening frame 11, and those that do not meet the requirements will remain in the second screening frame 11, which is conducive to completing the double graded screening of the resin particles through the synchronous work of the first screening frame 7 and the second screening frame 11 to improve the screening efficiency.
