Description

Technical Field

[0001] This utility model belongs to the field of auxiliary technology for start-up, shutdown and abnormal processes in carbon fiber and precursor production, specifically relating to an automatic waste fiber collector in the carbon fiber production process. Background Technology

[0002] Currently, waste fiber collection at carbon fiber production companies is entirely manual. This manual collection process increases the frequency of lint coming into contact with the human body, which may cause allergies.

[0003] This utility model relates to an automatic device for collecting carbon fiber, pre-oxidized fiber, and waste raw fiber. The device consists of a set of counter-rotating rollers, gears, a variable frequency motor, a cooling fan, a ton bag holder, an overall structure, and a movable pulley system. A clamp-type protective cover is installed at the inlet end of the counter-rotating rollers to prevent human hands from being caught in the rollers and causing mechanical injury. Openings on the clamp-type strips facilitate waste fiber collection. This automatic waste fiber collector ensures the required draw by adjusting the motor frequency. After being cooled by the fan, the waste fiber passes through a set of counter-rotating rollers and directly enters a pre-prepared ton bag. This avoids the hazards of allergies and pneumoconiosis that can occur during manual waste fiber collection, reduces unnecessary labor time, improves work efficiency, and achieves the goals of safe production, cost reduction, and efficiency improvement.

[0004] The above method cannot achieve full automation in the waste filament collection process. At the beginning of waste filament collection, the waste filament must be placed manually between the main shaft and the auxiliary shaft of the waste filament collector. After the ton bag is hung on the ton bag holder, the drive motor and fan are turned on to start waste filament collection. After the ton bag is full of waste filament, the power of the motor and fan is turned off, the waste filament is manually cut, and the ton bag is replaced. To prevent operators from being squeezed, cut, or electrocuted, the power to the drive motor and fan must be turned off when personnel are operating. Utility Model Content
