Abstract

The invention discloses a device for detecting foreign fibers in raw cotton. The device comprises a mechanical part and a control part; the mechanical part comprises a machine frame, a paving mechanism, a discharging conveying belt, a detection mechanism and a pneumatic removal mechanism; the feed end of the discharging conveying belt is positioned below the discharging end of the paving mechanism; the detection mechanism comprises a charge coupled device (CCD) camera and an illumination mechanism and is positioned above the middle part of the discharging conveying belt; the pneumatic removal mechanism is positioned below the discharging end of the discharging conveying belt; the control part comprises a programmable logical controller (PLC) and a CCD image processor; the PLC controls the CCD image processor to acquire raw cotton image signals from the CCD camera; and the CCD image processor judges whether foreign fibers are mixed in the raw cotton and feeds back a judgment result to the PLC, and the PLC controls the pneumatic removal mechanism to act. The invention also discloses a method for detecting the foreign fibers in the raw cotton by using the device. By the device and the method, the foreign fibers in the raw cotton are detected and removed.

Description

technical field [0001] The invention relates to a textile machine, in particular to a technology for effectively on-line detection and timely removal of foreign fibers in raw cotton by using CCD vision sensor technology and image processing technology according to production requirements. Background technique [0002] The presence of foreign fibers in raw cotton has long been a matter of great concern in my country's textile industry. Raw cotton refers to the fiber produced by separating the fiber from the cottonseed after the seed cotton is ginned. Foreign fibers refer to impurities such as hair and wool fibers mixed in raw cotton. Foreign fibers come from chemical fiber packaging materials and hemp ropes in the process of picking and purchasing raw cotton, human hair and animal hair mixed in during drying and storage, and non-cotton fibrous impurities mixed in processes such as cotton ginning. Mixing into cotton fibers will cause problems such as fabric appearance defect...
