Description

Technical Field

[0001] This utility model belongs to the field of injection molding machine processing, and in particular relates to a plastic granule mixing and stirring machine. Background Technology

[0002] Plastic granules are an indispensable basic raw material in the plastics industry, mainly processed from various plastic resins, and used to manufacture various plastic products. Heating is usually required during the mixing process of plastic granules. The main purpose of heating is to bring the plastic granules to a suitable melting temperature for molding. Specifically, the production process of plastic granules involves multiple steps such as mixing, melting, and extrusion to ultimately produce the desired plastic products. Therefore, during the mixing process, the plastic granules need to be heated to a molten state before molding.

[0003] Comparing this to Chinese Patent Publication No. CN 221271680 U, which discloses a plastic granule mixing mixer, the present invention includes a mixer body with a movable mixing mechanism inside. This invention uses a servo motor to drive a reciprocating screw to rotate. The reciprocating screw is threadedly connected to a moving block, causing the moving block to slide outside a limiting rod under force. The mixing blades contact the plastic granules, causing them to rotate inside a bearing under force. This allows the mixing blades to move and rotate simultaneously, thoroughly mixing the plastic granules. The operation is simple, quick, and convenient. By pressing the insertion rod, the rod pushes a sliding plate to slide inside a limiting groove, allowing the insertion rod to enter the mounting block and connect it to the mounting groove. The insertion rod is then subjected to a spring rebound force, securing it to the mounting groove and fixing the mounting block inside, facilitating installation and disassembly.

[0004] The disadvantages of the above-mentioned patent are: during the mixing process, some particles stick to the bottom of the barrel and cannot be fully stirred. Generally, heating devices heat the tank to make the plastic particles inside the tank reach the melting temperature, which has low heating efficiency and the temperature is not easy to control.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The inclined mixing tank drives the plastic granules to tumble forward, preventing some granules from sticking to the bottom of the tank and not being fully mixed. After mixing, the material can be automatically discharged, enabling continuous processing.
