Description

technical field [0001] The invention relates to the technical field of waste plastic reprocessing equipment, in particular to a feeding mechanism capable of releasing the adhesion of broken plastics. Background technique [0002] HDPE (High Density Polyethylene) particles are widely used in our lives. In industry, HDPE particles can be used to make pumps, pipes, containers and valves, etc., and can be used in chemical production sites that deal with corrosion and wear; in agriculture, HDPE particles can be used to make agricultural film, fertilizer packaging bags, water pipes and cement packaging Bags, etc.; in terms of building materials, HDPE particles can be used to make various building components, plastic doors and windows and plaster buckets, etc.; in daily life, HDPE particles can be used to make various plastic bags, toys, furniture, barrels, basins and stationery etc.; in the cosmetics industry, HDPE particles can be used to make cosmetics, ties, buttons and zipper...

AI Technical Summary

Problems solved by technology

[0003] The raw materials used in the manufacture of HDPE particles are usually PP (polypropylene), PE (polyethylene) and PET (polyethylene terephthalate resin). In order to protect the environment, the country encourages the recycling of waste plastics, so in When manufacturing HDPE pellets, new materials and old materials will be properly used together, and appropriate proportions of PP, PE and PET crushing materials will be selected according to customer requirements. For different types of plastics, appropriate proportions of new materials and old materials will also be selected. Put the final selected raw materials into the mixing device for mixing. After the raw materials are evenly stirred, they are sent to the injection molding machine through the feeding device for heating and plasticizing. The current feeding device is mainly composed of a feeding hopper. , a hopper, a drive motor, a screw conveyor rod and a feeding barrel, among which the feeding hopper is mostly a simple conical bucket, which is only responsible for introducing raw materials into the feeding barrel, and will not play other functions. It is relatively simple, because some raw materials sent into the upper hopper may not be completely mixed, and some raw materials may be stuck together. If the upper hopper can be used to remix the input raw materials, it can also be properly It would be even better to remove some of the adhesion between the raw materials, but the current loading hopper does not have such a function; the discharging hopper is usually a simple rectangular or conical frame, when the raw When the discharge hopper is sent out, there will be constant scraping between the raw material and the discharge hopper, which will cause huge wear and tear on the discharge hopper after a long time, causing the entire feeding device to be shut down to replace the discharge hopper, affecting production efficiency; the structure of the screw conveyor rod The screw conveying blade is simply set on the conveying rod. Due to the improper selection and combination of the pitch, the depth of the spiral groove, and the helix angle of the spiral blade, the screw conveying rod cannot be durable and efficient at the same time; at the same time, the raw materials entering the feeding device will have Some moisture, but the existing feeding device lacks a drying device and does not have the function of dehumidification

[0004] Therefore, the existing feeding device for conveying waste plastics to the injection molding machine has the problems of uneven mixing, sticking, serious wear, short service life, inability to balance durability and efficiency, and no dehumidification function
