Background

The high molecular chemical fiber material is a new material fiber which is widely applied at present, and the fiber material needs to be processed by a drawing frame when spinning production is carried out, wherein the drawing frame needs to be used for processing, the drawing frame is used for improving the internal structure of a sliver so as to improve the long section uniformity of the sliver, reduce the weight irregularity rate, straighten and parallel the fiber in the sliver and reduce hooks so that the fineness accords with the specification, the drawing frame consists of a feeding part, a drafting part, a sliver forming part and some automatic devices, the existing drawing frame can generate wire rod yarn defects during the production process, the yarn defects of the drawing frame can be divided into three types of mechanical wave irregularity, drafting wave irregularity and artificial yarn defects, and on a high-speed drawing frame, the proportion occupied by the mechanical wave irregularity yarn defects generated by poor mechanical state is the largest, mainly occurs in a drafting component, a transmission component, an outgoing line detection component and a cleaning device, shows that slivers have periodic uneven thickness, and in order to solve the problem of poor quality of outgoing line products, the existing drawing frame improves the cleaning device, reduces the shutdown times in the production process of the drawing frame and reduces mechanical waves.

Referring to the drawing frame drafting device of chinese patent publication No. CN104911764B, a curtain sleeve outer surface cleaning mechanism is connected to the drive roll shaft of the drive roll of the structural system of the automatic roll body cleaning mechanism, so that the curtain sleeve outer surface cleaning mechanism cleans the cleaning curtain sleeve in a moving state in an automatic manner and uninterruptedly, and short lint impurities adhered to the cleaning curtain sleeve are driven away from the cleaning curtain sleeve, which not only can reduce the working strength of the equipment maintenance personnel, but also can ensure the production efficiency of the drawing frame.

Referring to a new drawing process suitable for intelligent spinning with Chinese patent publication No. CN110442102A, the new drawing process based on a hybrid ring control system is constructed by introducing a generalized predictive control method with a PID structure into the drawing process, the open-loop control and the closed-loop control are fully combined, the advantages of the open-loop control and the closed-loop control are improved, the advantages of the open-loop control and the closed-loop control are exerted to the maximum extent, the control process can establish effective prediction on the future system output of the drawing machine only by utilizing process input and output data, and the quality of cotton slivers is effectively controlled by combining feedback signals, so that the automatic leveling and accurate control of the drawing machine is realized, and the drawing quality of the drawing machine is improved.

Referring to an on-line detection device of a drawing frame with Chinese patent publication No. CN102465372B, a sensor and a simple pressurizing device are additionally arranged on a traditional drawing frame, so that the structure is simple; the belt is matched with the tensioning wheel, so that the operation is flexible; the adjusting nut is matched with the spring, so that the pressure adjustment and the use are convenient; and the eddy current sensor is adopted, so that the detection is more accurate.
