Fiber strand detection device for four-roller ring frame

Abstract

The invention relates to a fiber strand detection device for a four-roller ring frame. The fiber strand detection device comprises a rear roller pair, a middle roller pair and a front roller pair, andslivers sequentially pass through the rear roller pair, the middle roller pair and the front roller pair to be fed into a spindle of the ring frame through a guide wire of the ring frame. The fiber strand detection device is characterized by further comprising an output roller pair, a capacitance fiber strand detector and a signal collecting unit. According to a detection device for yarn fiber strands at a spinning stage and a detection method for the yarn fiber strands at the spinning stage, the disadvantages of the prior art are avoided, the fiber strands at the spinning stage are detected,and basic data are provided for the study of the spinning principle, monitoring of spinning mechanical equipment, optimization of spinning technology parameter setting, and prediction, regulating andcontrolling of the yarn product quality in the spinning process.

Description

technical field [0001] The invention relates to a beard detection device of a ring spinning frame, in particular to a beard detection device based on the ring spinning technology of a four-roller drafting mechanism, and belongs to the technical field of textiles. Background technique [0002] The ring spinning frame is still the main equipment for producing spun yarn in the textile industry at this stage. The yarn forming process is as follows: the roving unwound from the roving bobbin on the hanging spindle is sent to the drafting device, and the strands output from the front roller are passed through the yarn guide hook. Supported by the traveler, it is pulled by the traveler to maintain a certain tension and wound on the spun yarn sleeve outside the spindle. The spindle drives the traveler to rotate through the yarn to twist the yarn. The forming rule is wound on the bobbin, and the spun yarn is formed. A four-roller ring spinning frame adds a set of output rollers to th...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: the core of ring spinning technology is ring twisting, that is, the fiber strands covered on the traveler are driven by the spindle to be wound on the bobbin and twisted. The movement of the winding mechanism makes the yarn strands in the spinning section not in a stable state for detection, resulting in the inability of the existing capacitive strand detectors to achieve accurate detection.
