[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen for polyester staple fibers which is easy to clean. Background Art

[0002] Polyester staple fiber, commonly known as "polyester", is a synthetic fiber obtained by spinning polyester formed by the condensation of organic dibasic acids and diols. It is a high molecular compound. When producing polyester staple fiber, the raw materials need to be vibrated and screened through a vibrating screen. The vibrating screen uses the principle of vibration motor excitation to make the raw materials be thrown up on the screen surface and move forward in a straight line to achieve the purpose of screening with a reasonably matched screen. It is widely used in the chemical industry, food industry, etc.

[0003] However, the screens in some polyester staple fiber vibrating screens are mostly fixed.
