Technical Field

[0001] The utility model relates to the technical field of PVC pipe production and processing, in particular to a central feeding device for PVC pipe production. Background Art

[0002] On a PVC pipe production line, the feeding process, as the beginning of the entire production process, has a decisive impact on the subsequent production process due to its efficiency and stability. Traditional PVC pipe production feeding devices are usually equipped with only a single discharge port. This design may meet the needs of small production lines or low-capacity environments, but in modern, large-scale production environments, its low feeding efficiency and uneven raw material distribution have gradually become prominent. Especially during peak production periods, the single discharge port design often cannot meet the needs of multiple production equipment operating simultaneously, resulting in serious production efficiency constraints.

[0003] In addition, due to the special properties of PVC raw materials, such as viscosity and agglomeration, the discharge port of traditional feeding devices is prone to blockage due to material adhesion or agglomeration after long-term operation. This not only affects the continuity of feeding and causes production interruptions, but also has an adverse effect on product quality. Therefore, in response to the above technical problems, a central feeding device for PVC pipe production is proposed. Utility Model Content
