Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic granule transfer technology, specifically to a transfer device for packaging plastic granules. Background Technology
[0002] Plastic granules are one of the basic raw materials for plastics. By uniformly processing plastics into granules, they facilitate the subsequent production and processing of plastic products. They are widely used in the production of various plastic products, such as plastic packaging, electronic product casings, toys, and household goods, and are also used in construction, automotive, medical, and agricultural fields. Based on application areas, they can be divided into general-purpose plastics and engineering plastics. Common general-purpose plastics include polypropylene, polyethylene, and polyvinyl chloride, while common engineering plastics include nylon, polytetrafluoroethylene, and polycarbonate.
[0003] After being packaged, the plastic granules need to be transferred from the production area to the stacking area for orderly stacking, and the packaged plastic granules are weighed so that they can be appropriately selected based on the weight parameters for subsequent use.
[0004] Because storage areas are generally far from production areas, transfer devices are typically used for transporting the plastic granules. Existing transfer devices for packaged plastic granules are generally transfer trolleys. Transport personnel must manually move the packaged plastic granules onto the trolley, then push the trolley through the workshop to the storage area for unloading. Next, the packaged plastic granules are manually weighed, and finally stacked in the appropriate location. Since packaged plastic granules are generally quite heavy, each step in the above process is time-consuming and labor-intensive, resulting in poor efficiency. Utility Model Content
