Automatic stopping device of cotton strip release cylinder of cotton spinning drawing frame

Abstract

The invention discloses an automatic stopping device of a cotton strip release cylinder of a cotton spinning drawing frame. The automatic stopping device comprises a cotton spinning outer frame and a cotton spinning rear beam, wherein a cotton strip cylinder is arranged under the side face of the cotton spinning rear beam, an L-shaped support is arranged on the cotton spinning rear beam and is fixed to the cotton spinning rear beam, through a first adjusting bolt, the L-shaped support is provided with a plurality of rectangular grooves, and a reflection type photoelectric relay is arranged under the L-shaped support and is movably arranged under the L-shaped support through a second adjusting bolt. A transmitting tube and a receiving tube are arranged on the reflection type photoelectric relay, and an optical grating formed by the transmitting tube and the receiving tube longitudinally and obliquely passes through the cotton strip cylinder. The automatic stopping device has the advantages of being reasonable in structure, convenient to install, convenient and quick to use and reliable in stop, adapts to various spinning drawing frames, overcomes the shortcoming that the cotton strip cylinder of the spinning drawing frame cannot timely stop, prevent waste product production and also effectively and completely eradicates fire hidden danger, and production safety is improved.

Description

technical field [0001] The invention relates to an automatic stop device, in particular to an automatic stop device for sliver take-off of a cotton drawing frame. Background technique [0002] Cotton spinning draw frame is a kind of textile machinery, that is, a spinning machine that processes several carded or combed fiber strips into fiber strips with certain quality requirements. The function is to improve the internal structure of the sliver, so as to improve the uniformity of its long segments, reduce the unevenness of the weight at the same time, make the fibers in the sliver straight and parallel, reduce the hooks, make the fineness meet the requirements, and make different types or different qualities of raw materials Mix evenly to reach the specified mixing ratio. At present, there are single-eye, double-eye, and four-eye draw frames for cotton spinning. A single-head draw frame that feeds multiple slivers into one sliver after merging and drafting is called a sin...

AI Technical Summary

Problems solved by technology

However, during the working process of the general cotton spinning draw frame, due to design defects, the sliver cannot be cut in time after the automatic can change, and the sliver is dragged between the empty can and the full can; or when the coiling disc starts to rotate The inertia is too large, so that the output sliver does not fall into the output sliver can, but is coiled outside the output sliver can

Since there is no such detection function at present, the cotton spinning draw frame will not stop, resulting in the production of slivers as waste products, reducing the production rate of finished products of the enterprise; even violent winding will cause fire accidents, and there is a great potential safety hazard
