Description

Technical Field

[0001] This utility model relates to the field of PET plastic sheet production technology, specifically to a stirring device for PET plastic sheet production that is easy to clean. Background Technology

[0002] A mixing device for PET plastic sheet production is a specialized piece of equipment used to mix PET resin, additives (such as masterbatches, plasticizers, stabilizers, etc.), and recycled materials to ensure uniform dispersion of raw materials to meet sheet forming requirements. The device mainly consists of a mixing tank, a drive system, a mixing mechanism, and a control system.

[0003] Existing mixing devices for PET plastic sheet production have significant shortcomings in terms of cleaning and maintenance: the cylinder is mostly a one-piece molded structure, and the connection between the inner wall and the mixing components forms a fixed dead corner, making it difficult to remove residual materials through conventional rinsing, and long-term use can easily breed pollution; the sealing area between the mixing shaft and the cylinder has gaps due to wear, and after the material seeps in, it forms a stubborn scale layer, which is difficult to clean to the sanitary dead corners by traditional disassembly and cleaning, affecting the efficiency of the device.
