[0002] Thermoplastic elastomer TPE / TPR, also known as artificial rubber or synthetic rubber, has the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, and at the same time has the characteristics of convenient processing and wide processing methods of ordinary plastics. It can be produced by injection molding, extrusion and blow molding. After the edges and corners of the sprue are crushed, 100% of them can be directly reused, which not only simplifies the processing process, but also reduces the processing cost. The use of thermoplastic elastomer sieve plates is also very common.

[0003] With the rapid development of sieve plates, the requirements for thermoplastic elastomer sieve plates are also increased. However, the existing thermoplastic elastomer sieve plates have a relatively low screening efficiency due to the fixed position of the sieve plates and sieve holes, which greatly affects the normal screening efficiency. In addition, in the existing screening process, it is very easy for the screened items to stick to the surface of the sieve plate. When the screened items stick to the surface of the sieve plate, it will affect the normal screening efficiency. Utility Model Content
