Fiber strand rough length measuring instrument winding preventing device

Abstract

The invention discloses a fiber strand rough length measuring instrument winding preventing device, and relates to the field of detection in the cotton textile industry. According to the invention, a length measuring roller is arranged between a left wallboard and a right wallboard, the top end of the left wallboard and the top end of the right wallboard are provided with a pressure roller support shaft, a pressure roller is connected with the pressure roller support shaft through a left pressure roller hanger and a right pressure roller hanger, and the pressure roller is in friction transmission with the length measuring roller. The winding preventing device is characterized in that the pressure roller support shaft is further provided with a yarn baffle plate hanger, a yarn baffle plate is connected with the pressure roller support shaft through the yarn baffle plate hanger, the yarn baffle plate is contacted with the pressure roller, the yarn baffle plate is an arc-shaped baffle plate, the radian of the yarn baffle plate is consistent with that of an outer arc of the pressure roller, the arc length of the yarn baffle plate is 430mm, the width is 20mm, the side, which is contacted with the pressure roller, of the yarn baffle plate is connected to a wool felt pad, the yarn baffle plate hanger comprises a left yarn baffle plate hanger and a right yarn baffle plate hanger, and one side of the pressure roller support shaft is provided with a handle. When a fiber strand is sticked and winds upwards, the yarn baffle plate and the wool felt pad keep off the up-winding fiber strand, the fiber strand falls back to the part below the length measuring roller again, the test goes on continuously, and occurrence of a sticking and winding phenomenon is avoided. The winding preventing device disclosed by the invention is simple in structure and convenient to use, improves the work efficiency and reduces repetition work.

Description

technical field [0001] The invention relates to the technical field of detection in the cotton textile industry, in particular to an anti-winding device for a sliver length measuring instrument. Background technique [0002] At present, in the cotton textile industry laboratory, the conventional sliver length measuring instrument does not have an anti-winding device. Due to the high humidity in the production environment of the cotton spinning mill, the surface of the instrument is wet and sticky, and the surface of the pressure roller is embedded, long-term use, wear, etc. The reason is that the experimental strands are very easy to wrap around the pressure roller, which may cause changes in the tension of the strands, or cause diameter changes and length inaccuracies after the lower pressure roll wraps the strands, especially when the above phenomena occur in the roving elongation test. , this group of samples must be discarded and re-sampled, but the sampling of roving el...

Problems solved by technology

[0002] At present, in the cotton textile industry laboratory, the conventional sliver length measuring instrument does not have an anti-winding device. Due to the high humidity in the production environment of the cotton spinning factory, the surface of the instrument is wet and sticky, and the surface of the pressure roller is embedded, long-term use, wear, etc. The reason is that the experimental sliver is very easy to wrap around the pressure roller, which may cause a change in the tension of the sliver, or cause the diameter to change and the length to be out of alignment after the sliver is wound by the lower pressure roller, especially when the above phenomena occur in the roving elongation test. , this group of samples must be discarded and re-sampled, but the sampling of roving elongation takes a long time, is difficult, and the sample size is large. After sampling, the roving spindle cannot continue spinning and forms a mechanical empty spindle, which affects normal production.
