Description

Technical Field

[0001] The present invention relates to the technical field of plastic processing, and specifically to equipment for integrated drying and plasticizing injection molding processing. Background Art

[0002] Equipment for integrated drying and plasticizing injection molding processing is equipment that integrates the drying and plasticizing processes of plastic raw materials. This can improve production efficiency, ensure product quality, and reduce energy consumption. Usually, plastic pellet raw materials need to be put into a drying hopper. Under the action of heating and hot air circulation, the moisture in the raw materials is removed. The dried raw materials enter the barrel, where they are plasticized by heating and the rotation of the screw, and finally are injected into the mold for molding. In common plastic pellet hopper dryers, due to different specifications and sizes of the plastic thermoplastic pellets put in, they are stacked and squeezed against each other in the drying bin, forming a relatively compact structure. It is difficult for hot air to enter the gaps between the pellets, resulting in a faster temperature rise of the outer plastic pellets and a slower temperature rise of the inner plastic pellets, thus causing uneven drying effect of the overall pellets and affecting product quality. Secondly, during the drying process, dust particles will adhere to the surface of the conical screen at the bottom of the hopper due to the action of air flow and electrostatic adsorption, blocking the conical screen. The hot air flow will cause the local temperature at the blocked part of the conical screen to rise, and then cause the plastic pellets to agglomerate, further affecting the injection molding efficiency. In view of the above problems, the inventor proposes equipment for integrated drying and plasticizing injection molding processing to solve the above problems. Summary of the Invention

[0046] By adopting the above technical solution, the rotating material spreading frame 404 rotates on the fixed ring plate 409.

[0047] Working principle: First, the plastic particle raw materials are put into the drying cylinder 2 through the feed port. The plastic particles fall to the bottom of the drying cylinder 2 along the first inclined baffle 8 and the second inclined baffle 9 in sequence. The hot air component 3 is turned on, and the hot air component 3 conveys the drying hot air into the inside of the housing 1 and enters the drying cylinder 2 from the conical net at the bottom of the drying cylinder 2 to contact the granular material. As Figure 2 、 Figure 9 shown, control the first motor 407 to drive the second gear 408 to rotate clockwise. The second gear 408 drives the rotating shaft 402 and the spiral fan blade 403 to rotate counterclockwise through the first gear 405 to convey the plastic particles at the bottom of the drying cylinder 2 vertically upward along the inner cylinder 401 to the rotating material spreading frame 404. While the second gear 408 rotates, it drives the rotating material spreading frame 404 to rotate clockwise through the first toothed ring 406. The conveyed plastic particles are evenly spread in the drying cylinder 2 by the reverse rotation of the rotating material spreading frame 404 and the rotating shaft 402. In this way, the plastic particles flow in the drying cylinder 2 in a reciprocating cycle, increasing the contact area between the plastic particles and the hot air and accelerating the uniform conduction of heat in the plastic particles. After drying, turn off the first motor 407 and turn on the second motor 619 at the same time. As Figure 5 、 Figure 11 shown, the drive end of the second motor 619 drives the drive shaft 614 to rotate. The drive shaft 614 drives the transmission shaft 615 to rotate through the third bevel gear 617 and the fourth bevel gear 618. The transmission shaft 615 drives the rotating toothed ring 603 and the cleaning fixed frame 604 to rotate on the circular track 602 through the fixed gear 616. During the rotation of the cleaning fixed frame 604, the driving shaft 609 is driven to rotate through the fixed toothed ring 611 and the rotating gear 610. As Figure 12As shown, the driving shaft 609 drives the driven shaft 607 to rotate through the first bevel gear 612 and the second bevel gear 613. The driven shaft 607 drives the cleaning shaft 605 and the cleaning roller 606 to rotate through the universal coupling 608. The cleaning roller 606 cleans the dust adhering to the surface of the bottom conical screen of the drying cylinder 2, as Figure 7 , Figure 13 shown. While the driving shaft 614 rotates, it drives the slider 707 to reciprocate on the slide rail 706 through the rotating rod 709 and the guiding frame 710. The slider 707 drives the second toothed ring 702 to rotate reciprocally on the fixed circular frame 701 through the connecting rod 708. The second toothed ring 702 drives the four corresponding toothed plates 703 to move reciprocally centripetally through the four transmission gears 704. The four toothed plates 703 reciprocally open and close to achieve the effect of intermittent feeding. The dried plastic particles are intermittently discharged into the feeding cylinder 5, and are plasticized in the cylinder 5 through heating and the rotation of the screw, and finally are injected into the mold for molding.
