Description

Technical Field

[0001] The utility model relates to the technical field of feeding, such as entering the inner cavity of a model, and in particular to a feeding and dust removal device for producing PVC plastic materials. Background Art

[0002] Polyvinyl chloride, abbreviated as PVC in English, is the third largest synthetic polymer plastic in the world. PVC was once the world's largest general-purpose plastic and is widely used. PVC is available in two types: hard (sometimes abbreviated as RPVC) and soft. Hard polyvinyl chloride is used in building pipes, doors and windows. It is also used to make plastic bottles, packaging, bank cards or membership cards. Adding plasticizers can make PVC softer and more flexible. It can be used in pipes, cable insulation, flooring, signs, phonograph records, inflatable products and rubber substitutes.

[0003] When PVC plastic is produced, it needs to be processed through raw materials to obtain finished plastics. Dust will be mixed into the raw materials at ordinary times. During processing, the dust will affect the quality of the finished PCV plastic. Therefore, a dust removal device is required to be set in the feeding device to remove dust from the raw materials. The feeding device does not control the flow of the raw materials, so more raw materials will be transported at one time. These raw materials will pile up together, and the dust removal device cannot effectively remove the dust in the raw materials, which will reduce the quality of the plastic. Utility Model Content
