Technical Field
The utility model relates to the field of chemical fiber spinning, in particular to an industrial yarn sucking device which is mainly used for sucking cut tows immediately in the drafting process of polyamide and polyester industrial yarn in the field of chemical fiber and preventing the cut tows from winding a roller to further influence production.
Background
The spinning and drafting process for industrial yarn of nylon, polyester, etc. includes the steps of feeding the melt after melting and mixing to spinning nozzles of spinning box for spinning, cooling and forming fiber, oiling, drafting and winding into yarn tube with winding head.
In the production process of industrial yarn spinning and drafting in the chemical fiber field, nylon, terylene and the like, the broken ends are wound suddenly in the production process usually due to temporary equipment failure, and the broken tows can be wound on the hot drafting roller, so that a large workload of cleaning waste yarns on the hot drafting roller before spinning again can be brought, and a large waste yarn rate can be brought at the same time. At present, many manufacturers commonly adopt a manual hook knife or a filament cutter device to cut off tows, and a suction gun or a conventional civil filament suction device is used for sucking the cut tows away so as to prevent the tows from being wound on a roller; however, the following problems exist: firstly, the cut tows are sucked away by using a suction gun manually, so that certain time delay is generated, and part of the tows can be wound on a hot drawing roller, so that the waste silk rate is increased; secondly, manual operation is needed, so that the working intensity and labor cost of workers are increased; thirdly, the conventional civil silk suction device used for industrial silk such as chinlon, terylene and the like has the following defects: the single-filament fineness and the total filament bundle of industrial yarns such as nylon, terylene and the like are far larger than those of civil yarns, and the strength and the elasticity of the yarns are also far larger than those of the civil yarns, so that the development of a high-suction and impact-resistant yarn suction device for the industrial yarns is required.
Disclosure of Invention

The technical scheme of the utility model is as follows: the utility model consists of a two-position three-way electromagnetic valve, a PU air inlet pipe, a straight-through terminal joint, a wire passing pipe, a rear end sealing ring, an airflow lining, a front end sealing ring and a wire suction port flange; the air flow bush is embedded in the inner cavity of the wire passing pipe through a wire suction port flange, a front end sealing ring and a rear end sealing ring at the wire feeding end of the wire passing pipe in sequence; a plurality of inclined vent holes forming included angles with the axis and the longitudinal line are uniformly distributed on the airflow lining; the two-position three-way electromagnetic valve is connected with the PU air inlet pipe into a whole and is communicated with the inclined vent hole through a straight-through terminal joint. In the normal spinning and drafting production process of industrial yarns such as nylon, terylene and the like, tows enter a drafting roller through the front end of a filament suction port flange at the filament inlet end of a filament passing pipe and are fed into a winding head to be wound into a filament tube through drafting. When equipment has temporary faults, the winding suddenly breaks, the winding head automatically sends a broken yarn detection switch signal, the filament cutter device immediately cuts off filament bundles, and meanwhile, the two-position three-way electromagnetic valve is controlled to be started, compressed air enters the air flow lining through the PU air inlet pipe and the straight-through terminal connector and passes through a plurality of inclined air holes of the air flow lining to form high-speed spiral air flow to be conveyed to the filament outlet end of the filament passing pipe, so that great spiral suction force is generated at the flange inlet of the filament suction port, the cut industrial filament bundles such as chinlon, terylene and the like are sucked into the filament passing pipe, and meanwhile, the filament bundles are sent into the waste filament box under the driving of the high-speed spiral air flow, so that the filament bundles are prevented from being wound on the heat drafting roller. And after the fault processing is finished, the two-position three-way electromagnetic valve is disconnected, and the head is recovered for normal production.
Preferably, the airflow lining is made of polytetrafluoroethylene, so that the impact of industrial yarns such as chinlon and terylene on the airflow lining can be effectively reduced, and the noise of the working environment is reduced.
The utility model has the beneficial effects that: the device can automatically and quickly suck the cut industrial yarn bundles such as nylon, terylene and the like to the waste yarn box so as to prevent the yarn bundles from winding the hot drawing roller, reduce the time for manually cleaning the roller and improve the working efficiency. The oblique air holes uniformly distributed on the air flow lining can quickly improve the air flow speed and form spiral cohesion, axial conveying force and circumferential cohesion force to the tows can be effectively provided, and the generated circumferential cohesion force can be used for carrying the tows in a centralized manner and can also prevent the tows from floating around under the action of compressed air.
