Description

Technical Field

[0001] The utility model relates to the technical field of wire suction devices, in particular to a wire suction device for carbon fiber bundles. Background Art

[0002] The carbon fiber tow suction device is a device used in the carbon fiber production process. Its main function is to absorb and transport the carbon fiber tow during the production process. This device usually consists of an air inlet pipe, a suction port, a wire outlet pipe and a jacket. The working principle is that compressed air enters the annular chamber and then enters the wire outlet pipe from the gap between the wire outlet pipe and the suction port to form a downward jet, thereby driving the carbon fiber tow downward. The design of the pneumatic suction device is to simplify the operation process, reduce labor intensity, and improve production efficiency.

[0003] Carbon fiber tows carry some impurities during the production process, such as metal ions, dust, grease, etc. These impurities will remain inside the device during the pneumatic suction process. The common cleaning method is to use high-pressure water jet cleaning to improve the cleaning effect and reduce impurity residues.

[0004] However, when using a high-pressure water jet to clean the inside of the pneumatic suction device, the water flow will enter the annular chamber. The water flow entering the annular chamber will change the original airflow channel, resulting in an increase in airflow resistance, and then cause pressure loss. This pressure loss will reduce the working efficiency of the pneumatic suction device. For this reason, a suction device for carbon fiber tow is proposed. Utility Model Content
