Description

Drying and plasticizing integrated injection molding equipment

Technical Field

The invention relates to the technical field of plastic processing, in particular to equipment for drying, plasticizing and integrated injection molding processing.

Background Art

The drying and plasticizing integrated injection molding equipment is a device that integrates the drying and plasticizing processes of plastic raw materials, which can improve production efficiency, ensure product quality and reduce energy consumption. It is usually necessary to put the plastic granule raw materials into the drying hopper. Under the action of heating and hot air circulation, the moisture in the raw materials is removed, and the dried raw materials enter the barrel. Plasticization is carried out in the barrel by heating and rotation of the screw, and finally injected into the mold for molding. The commonly used plastic granule hopper dryer has different specifications and sizes of plastic thermoplastic particles. They are piled up and squeezed against each other in the drying bin to form a relatively tight structure. It is difficult for hot air to enter the gaps between the particles, so that the temperature of the outer plastic particles rises quickly and the temperature of the inner plastic particles rises slowly, which leads to uneven drying effect of the overall particles, affecting product quality. Secondly, during the drying process, the cone net at the bottom of the hopper will adhere to dust particles on the surface of the cone net due to the action of airflow and electrostatic adsorption, blocking the cone net. The hot air flow will increase the local temperature at the blockage of the cone net, thereby causing the plastic particles to agglomerate, thereby affecting the injection molding efficiency. In view of the above problems, the inventor proposes a drying and plasticizing integrated injection molding equipment to solve the above problems.

Working principle: First, the plastic granule raw material is put into the drying cylinder 2 through the feed port, and the plastic granules fall to the bottom of the drying cylinder 2 along the No. 1 inclined baffle 8 and the No. 2 inclined baffle 9 in turn, and the hot air component 3 is turned on. The hot air component 3 conveys the dry hot air to the inside of the shell 1 and enters the drying cylinder 2 from the cone net at the bottom of the drying cylinder 2 to contact the granular material. As shown in Figures 2 and 9, the No. 1 motor 407 driving end is controlled to drive the No. 2 gear 408 to rotate clockwise, and the No. 2 gear 408 drives the rotating shaft 402 and the spiral blade 403 to rotate counterclockwise through the No. 1 gear 405 to rotate the plastic granules at the bottom of the drying cylinder 2 vertically upward along the built-in cylinder 401. The plastic particles are transported to the rotating material spreading frame 404, and the rotating material spreading frame 404 is driven to rotate clockwise through the No. 1 gear ring 406 while the No. 2 gear 408 rotates. The rotating material spreading frame 404 rotates in the opposite direction to the rotating shaft 402 to evenly spread the transported plastic particles in the drying cylinder 2. This reciprocating cycle allows the plastic particles to flow in the drying cylinder 2, thereby increasing the contact area between the plastic particles and the hot air and accelerating the effect of evenly conducting heat in the plastic particles. After drying is completed, the No. 1 motor 407 is turned off and the No. 2 motor 619 is turned on, as shown in Figures 5 and 11. The driving end of the No. 2 motor 619 drives the driving shaft 614 to rotate, and the driving shaft 614 is driven by the No. 3 motor 407. The bevel gear 617 and the fourth bevel gear 618 drive the transmission shaft 615 to rotate, and the transmission shaft 615 drives the rotating gear ring 603 and the cleaning fixed frame 604 to rotate on the circular rail 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 gear ring 611 and the rotating gear 610. As shown in Figure 12, 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 rotates along the conical mesh surface at the bottom of the drying cylinder 2. 7 and 13, while the driving shaft 614 rotates, the slider 707 is driven to reciprocate on the slide rail 706 through the rotating rod 709 and the guide frame 710, and the slider 707 drives the second gear ring 702 to reciprocate on the fixed circular frame 701 through the connecting rod 708.
