Technical Field

[0001] The utility model relates to the technical field of vibrating sieving machines, in particular to a vibrating sieving machine for thermoplastic polyurethane rubber particles. Background Technique

[0002] As is well known, thermoplastic polyurethane (TPU) is a thermoplastic elastomer that can be melt-processed, with high durability and flexibility, combining the characteristics of plastics and rubbers. Therefore, it has characteristics such as durability, flexibility, and excellent tensile strength, meeting the requirements of many demanding applications, and thus has been widely used.

[0003] Currently, in the process of producing and processing thermoplastic polyurethane rubber particles, corresponding screening devices are often required to screen out particles of standard size for subsequent use. However, the inventor of the present utility model has found that during the use of traditional vibrating sieving machines, due to the long-term use of the sieve mesh, impurities and plastic chips are likely to accumulate on its surface or in the sieve holes. If not cleaned in time, these debris and impurities are likely to adhere to the sieve holes, resulting in a reduction in the screening efficiency of the vibrating sieving machine and insufficient practicality.

[0004] Therefore, in view of the above related technologies, we propose a vibrating sieving machine for thermoplastic polyurethane rubber particles. Content of the Utility Model
