Abstract
Description
Technical Field
[0001] The utility model relates to the field of particle classification, in particular to a feeding device for producing polyvinyl chloride. Background Technique
[0002] Polyvinyl chloride (PVC) is a common thermoplastic plastic, which is obtained by polymerizing vinyl chloride monomers. Polyvinyl chloride has high durability and can resist most common chemical substances and physical damages, which makes it a commonly used material suitable for products with long-term use and exposure to harsh environmental conditions. Due to the low conductivity and good electrical insulation performance of polyvinyl chloride, it is widely used in the electronics field for manufacturing electrical equipment such as wires, cables, plugs, and sockets. Polyvinyl chloride can be added with different pigments and colorants according to needs to obtain various colors and transparencies. It can also be surface decorated through processes such as surface treatment, printing, and coating to meet the requirements of different application fields. Polyvinyl chloride can be made into various shaped products through forming processes such as blow molding, injection molding, and extrusion. Its melting point is relatively low, making it easy to process into various complex shapes and sizes. This forming performance makes polyvinyl chloride an ideal choice for manufacturing products such as pipes, plates, window frames, wires, and cables.
[0003] During the plastic processing process, when mixing raw materials, if the mixing is not sufficient or the time is not long enough, the strip-shaped plastic raw materials after drawing and cooling are fed into the granulator, and the granulator cuts the strip-shaped plastic raw materials into particles, which will result in uneven particle sizes. The uneven particle sizes of the produced particles will affect the later use.
