Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding of raw materials in pipe production, in particular to a side feeding device. Background Art

[0002] Extrusion processing is one of the most widely used processing methods in polymer production and processing. It is usually used to extrude granules or powders to form products such as pipes, plates, profiles, films, etc. The working process of extrusion processing mainly includes feeding, conveying, melting, and extrusion molding. In general, solid granules, flakes or powders are fed into the extruder. For such materials, the self-weight feeding method is used to achieve continuous feeding of materials. At present, most of the traditional pipe production processes use a single feeding method, that is, only one feeding port is set at the end of the extruder screw for feeding, and this feeding method can only feed gradually, and cannot feed too much at one time, so the final pipe production capacity is not high enough. At the same time, in the production process, special products with other colors are replaced. Using the traditional feeding method, it is necessary to mix the masterbatch with the main material of the product in a certain proportion before production. There is a certain risk of mixing miscellaneous materials into the raw materials during the mixing process, resulting in impure product color. At the same time, during the material change process, the extruder and hopper need to be cleaned, which reduces production efficiency. There is also the problem of color difference in the products produced due to uneven mixing. Utility Model Content
