Description

Technical Field

[0001] The utility model relates to the technical field of polyester staple fiber waste silk recycling, in particular to a waste silk recycling device. Background Technique

[0002] Polyester staple fiber is made of polyester (i.e., polyethylene terephthalate, abbreviated as PET, polymerized from PTA and MEG). Generally, polyester staple fiber can be produced through two main processes: pre-spinning and post-spinning. According to different requirements, polyester staple fiber of different specifications can be cut in post-spinning. The polyester filaments that do not meet the requirements in the first production process of polyester, as well as the polyester waste blocks in the polyester section, off-grade slices in the granulation process, discharge filaments in the spinning room, and drawing waste filaments in the winding and post-treatment sections during the production process of polyester are all polyester waste silk. Polyester waste silk has good recycling value, so a waste silk recycling device will be used.

[0003] In the prior art, the application number CN202321766018.3 proposed a waste silk recycling device during the production process of polyester staple fiber. After the waste silk falls onto the separation plate, the electric heating tubes directly below both sides of the bottom of the separation plate are started to heat up, so as to fuse the waste silk in contact on the separation plate. The water spray head sprays liquid to cool the fused waste silk. The liquid falls through the holes of the separation plate, and the cleaning push plate pushes the waste silk from the separation plate to the discharge port for delivery under the action of the electric push rod.

[0004] However, during the use of the above patent, by heating and pressurizing the waste silk, the waste water is fused into one body. However, after the fused waste water is pushed out in the above patent, manual collection of the fused waste silk is still required, and it takes time to cool the fused waste silk to prevent scalding the staff. Therefore, a waste silk recycling device is proposed. Content of the Utility Model
