Description

Technical Field

[0001] The utility model relates to a waste collecting device, in particular to a waste collecting device used in rubber production. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a molecular weight that is often large, greater than hundreds of thousands. The production process of rubber is very complicated, including basic processes such as plasticizing, mixing, calendering or extrusion, molding and vulcanization. Each process has different requirements for the product and is combined with several auxiliary operations. In order to add various required compounding agents to rubber, the raw rubber must first be plasticized to improve its plasticity; then carbon black and various rubber additives are mixed with rubber to form a rubber compound through mixing; the rubber compound is extruded to form a certain shape blank; then it is combined with a textile material (or metal material) that has been calendered or coated with glue to form a semi-finished product; finally, the plastic semi-finished product is made into a highly elastic final product through vulcanization. In the production process of rubber products, the cut scraps generally need to be collected to facilitate recycling, and this device is a waste collection device for rubber production;

[0003] For a waste collection device for rubber production with the authorization announcement number CN 214644149 U, the beneficial effects of the utility model are: the waste can be input into the box at a stable speed by the rotational cooperation between the guide component and the guide cavity, and the lifting component adjusts the height of the push plate and cuts and refines the waste through the rotating cutting component, so that the waste can be divided into small pieces, which is convenient for centralized recycling and reuse;

[0004] The cutting assembly provided in the above-mentioned device is mainly used for cutting by spiral blade conveying. Thus, some shorter rubber materials may be scraped into the box without passing through the cutter during conveying. Thus, the above-mentioned device has poor shredding effect on some shorter rubber scraps. Secondly, when the waste rubber shredded by the above-mentioned device is recycled, it needs to be shredded again. Thus, the processing flow of the rubber scraps can be increased, thereby increasing the operation steps, slowing down the production efficiency, and reducing the practicability of the device.
