Description

Technical Field

[0001] The utility model relates to the technical field of polyester production, in particular to a static electricity removal device in the polyester production process. Background Art

[0002] Polyester, also known as polyester fiber or PET fiber, is a synthetic fiber. Polyester occupies an important position in synthetic fibers. It is known for its easy availability of raw materials, excellent performance, and wide range of uses. It has the characteristics of stable quality, good strength and wear resistance, and not easy to deform. In the production and processing of polyester, static electricity will affect the quality of polyester products and even affect the overall processing process. Therefore, a polyester filament production process static electricity removal device is needed to eliminate static electricity during polyester production. However, the current polyester production process static electricity removal device still has the following shortcomings:

[0003] For example, the patent document with application number 202322453623.1 discloses a polyester fiber static elimination device. The polyester fiber static elimination device sprays antistatic agent on the polyester fiber below through multiple groups of atomizing nozzles, allowing the antistatic agent to penetrate into the polyester fiber to preliminarily eliminate the static electricity generated by the friction between the polyester fiber production process and the transportation process. Then, when the polyester fiber that has been preliminarily treated passes under the static brush, the electric slide rail and the electric slider drive the static brush to brush the polyester fiber back and forth. However, it is inconvenient to adjust the tension of the polyester fiber during the static elimination process, which makes the polyester fiber easy to break due to excessive tension, causing certain losses.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a static electricity removal device for polyester production process is proposed. Utility Model Content
