Description

Technical Field

[0001] The invention relates to the technical field of wool spinning equipment, in particular to a pre-spinning needle comb and wool oil flow online monitoring instrument. Background Art

[0002] Wool oil is a kind of oil added to wool fiber materials in wool spinning process. It can give loose fibers smooth, soft and antistatic properties. Softener ingredients are added to wool oil to obtain a better feel. The role of wool oil is to adjust the static and dynamic friction coefficients between fibers, reduce the friction between fibers and guide rollers, prevent and eliminate static electricity generated by friction in processes such as drafting and twisting, and improve the cohesion of fiber bundles. This is to facilitate wool fibers to pass through combing, spinning and other equipment smoothly, and prevent loose hair, entanglement, and broken ends.

[0003] The amount of wool oil sprayed and added and the spray stability have an important impact on the wool pre-spinning rate and equipment operation efficiency. Therefore, a wool oil addition monitoring device needs to be set up during the wool oil spray addition process. The existing wool oil flow monitoring device can only monitor the amount of wool oil added, and cannot timely alarm and stop when the wool oil is under-pressure or does not spray normally, which causes the operator to fail to find the situation of wool oil spray under-pressure or untimely spraying in time, which affects the wool top production rate; in addition, the existing wool oil contains some granular impurities, and the existing wool oil flow online monitoring device lacks granular impurity filtering. The granular impurities directly enter the wool oil flow online monitor, which will cause the wool oil flow online monitor to measure inaccurately and affect the service life of the wool oil flow online monitor.
