Description
Technical Field
[0001] The invention relates to the technical field of twin-screw extruders, and in particular to an ABA environmentally friendly recycling PE twin-screw extruder device. Background Art
[0002] Twin-screw extruder equipment is developed on the basis of single-screw extruder equipment. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics, it has been widely used in the molding of extruded products. After the material enters the barrel from the feeding port, it is pushed forward with the rotation of the screw. In this process, the meshing area of the two screws shears, extrudes and stirs the material, causing the material to undergo heating, melting, mixing, plasticizing and other processes, and finally extruded from the die. In practical applications, according to different process requirements, the screw structure, aspect ratio, heating and cooling methods of the twin-screw extruder can be adjusted and optimized, so that the aspect ratio of the twin screw is very good, the stretching ratio and strength are also good, and the twin-screw extruder has a better mixing effect, which can make the material more evenly mixed in a short time, especially for complex formulas with multiple additives.
[0003] ABA material can be the same material or different materials. Material B is inferior to material A, and material A is better. The raw materials produced in this way have low cost, impact resistance, tensile resistance, and high material strength. Before processing the PE extrusion bag, the particles need to be heated. When the extrusion equipment heats plastics and other materials, hot air may be generated. The generation of these hot gases is mainly due to the release of the material from a solid state to a molten state by the heating system of the extrusion equipment. When the heating system heats the plastic particles, some of the hot air may return to the hopper. Since the hopper is usually a conventional open inverted cone structure and cannot discharge these hot gases, the inner wall of the hopper and the material may become damp, and the particles will adhere to the wall of the hopper. At the same time, the plastic particles may be blocked when they continue to pass through the hopper, thereby interfering with the normal feeding speed of the particles. Summary of the invention

[0013] The beneficial effects of the present invention are as follows:
[0014] 1. The present invention provides a feeding component, continuously feeds particles into the feeding hopper, turns on the second motor, and drives the connecting shaft to rotate in the feeding hopper through the output end of the second motor, so that the connecting plate follows the connecting shaft to rotate in the feeding hopper, so that the connecting plate drives the rotating rod to rotate and stir the particles continuously entering the feeding hopper, thereby avoiding blockage caused by the particles continuously passing through the feeding hopper, and at the same time drives the connecting plate to rotate through the connecting shaft, so that the connecting plate drives the cleaning mechanism to clean the inner wall of the feeding hopper, and at the same time, when the rotating rod is driven to rotate by the connecting plate, the rotating rod and the extrusion mechanism are squeezed, so that the side of the rotating rod can be cleaned, thereby avoiding that when the rotating rod is in contact with the particles for a long time and some particles will adhere to the rotating rod, thereby interfering with the normal rotation and evacuation of the rotating rod.

At the same time, the heating box 2 is turned on to heat the particles in the extrusion component 4.
[0042] By continuously feeding particles into the hopper 31, turning on the second motor 33, and driving the connecting shaft 34 to rotate in the hopper 31 through the output end of the second motor 33, the connecting plate 35 follows the connecting shaft 34 to rotate in the hopper 31, so that the connecting plate 35 drives the rotating rod 37 to rotate and stir the particles continuously entering the hopper 31, thereby avoiding blockage caused by the particles continuously passing through the hopper 31. At the same time, the connecting plate 35 is driven to rotate by the connecting shaft 34, so that the connecting plate 35 drives the cleaning mechanism 39 to clean the inner wall of the hopper 31. At the same time, when the rotating rod 37 is driven to rotate by the connecting plate 35, the rotating rod 37 and the extrusion mechanism 38 are extruded, so that the side of the rotating rod 37 can be cleaned, thereby avoiding that when the rotating rod 37 is in contact with the particles for a long time, some particles will adhere to the rotating rod 37, thereby interfering with the normal rotation and evacuation of the rotating rod 37.
[0043] When the rotating rod 37 is driven by the connecting plate 35 to contact the extrusion shell 381, the moving grooves 382 are evenly opened on the side of the extrusion shell 381, so that when the rotating rod 37 rotates in the inner cavity of the feeding hopper 31, the extrusion plate 385 can contact and extrude the rotating rod 37, and at the same time, the contact block 451 is provided on the side of the extrusion plate 385, so that the side of the rotating rod 37 can be squeezed and cleaned, thereby preventing the particles entering the feeding hopper 31 from sticking when the weather is hot. When the rotating rod 37 is stirring and evacuating the particles, the particles will adhere to the side of the rotating rod 37, thereby interfering with the rotating rod 37's rotation and dredging work. At the same time, when there are particles between the extrusion block 387 and the extrusion plate 385 and the rotating rod 37, the extrusion force during contact is too large, so that the extrusion plate 385 can slide in the moving groove 382 through the sliding rod 384, thereby avoiding excessive extrusion force between the extrusion plate 385 and the rotating rod 37, which will cause extrusion damage to the rotating rod 37 and the extrusion plate 385.
[0044] When the connecting shaft 34 is driven by the output end of the second motor 33, the connecting shaft 34 drives the connecting plate 35 and the cleaning rod 391 to rotate in the hopper 31, so that the moving rod 393 drives the cleaning plate 394 to disengage from the square groove 392 through the action of centrifugal force, so that the cleaning plate 394 drives the rubber plate 396 and the bent plate 397 to clean and scrape against the inner wall of the hopper 31, thereby preventing the particles from entering the hopper 31. The particles themselves are adhered with excess dust and impurities, which will remain in the hopper 31 when passing through the hopper 31. On the inner wall of the hopper 31, a rubber plate 396 is arranged. When the rubber plate 396 contacts the inner wall of the hopper 31, the rubber plate 396 can squeeze out the particles adhering to the inner wall of the hopper 31, thereby preventing the particles from adhering to the inner wall of the hopper 31 when the weather is hot. At the same time, the angle of the bent plate 397 is greater than the rubber plate 396, so that when the connecting plate 35 rotates, the bent plate 397 can rotate against the inner wall of the hopper 31, so that the bent plate 397 can scrape off the dust and impurities adhering to the inner wall of the hopper 31;
[0045] The particles in the hopper 31 enter the extrusion housing 41 through the feeding port 42. By setting two feeding ports 42, when the output end of the first motor 5 rotates forward to drive the threaded rod 43 to feed, two groups of different particles can be placed at the same time for extrusion feeding. At the same time, when the threaded rod 43 drives the particles to feed, the limiting plate 44 and the contact mechanism 45 are taken out of the extrusion housing 41, so that the threaded rod 43 can feed. At the same time, when the threaded rod 43 completes the feeding work, the limiting plate 44 and the contact mechanism 45 are removed from the extrusion housing 41, so that the threaded rod 43 can feed. After the contact mechanism 45 is installed, the second motor 33 is turned on, and the second motor 33 is reversed to drive the threaded rod 43 to rotate in the inner cavity of the extrusion shell 41. At the same time, the contact mechanism 45 is driven by the threaded rod 43 to move in the inner cavity of the extrusion shell 41, so as to clean the inner wall of the extrusion shell 41, thereby preventing a large amount of particle residue from remaining on the inner wall of the extrusion shell 41 when the threaded rod 43 is rotating and feeding in the inner cavity of the extrusion shell 41, so that the threaded rod 43 needs to be disassembled and cleaned;
[0046] When the output end of the first motor 5 is reversed to drive the threaded rod 43 to rotate in the inner cavity of the extrusion shell 41, after the contact block 451 and the limit plate 44 are installed with the extrusion shell 41, a thread groove 452 is opened on the inner wall of the contact block 451, so that when the contact block 451 is installed, the thread groove 452 on the contact block 451 is threadedly connected with the side of the threaded rod 43, and the threaded rod 43 is reversed by the output end of the first motor 5, so that the contact block 451 moves on the threaded rod 43, so that the scraper assembly 453 cleans the inner wall of the extrusion shell 41, and the threaded rod 43 is threadedly rotated in the thread groove 452, so that the particle residues remaining on the threaded rod 43 can be cleaned and dropped;
[0047] When the contact block 451 moves on the threaded rod 43, the scraper 4531 drives the arc plate 4544 to contact and clean the inner wall of the extrusion shell 41, so that the arc plate 4544 can scrape off the granular impurities attached to the inner wall of the extrusion shell 41. When there are too many impurities attached to the inner wall of the extrusion shell 41, the scraper 4531 is subjected to the extrusion force and slides in the installation groove 454 through the sliding rod 4532. At the same time, the stretching effect of the third spring 4533 is used to avoid excessive extrusion force between the scraper 4531 and the impurities, thereby preventing the scraper 4531 and the arc plate 4544 from causing extrusion damage.
