Description

The invention relates to the preparatory department of the weaving of the textile industry and relates to the process of sizing the main threads.

Known sizing machine, which uses two separate impregnation baths with dressing, separate intermediate drying drums on which pre-dried threads are combined into one filling line and dried (Process Theory, technology and equipment for preparatory weaving operations: Textbook for universities / S.D. Nikolaev, R.N. Sumarokova, S.S. Yukhin, et al. - 2nd ed. Revised and revised - M.: Legprombytizdat. 1993. - 192 p. 127).

The main disadvantages of this machine are the complexity of refueling, difficulties in maintenance and significant overall dimensions.

Known sizing machine (patent for a utility model of the Russian Federation No. 133531, IPC D06B 3/06, 2013), adopted as a prototype containing a rack with main shafts, an adhesive device, a drying device consisting of pre-drying drums, a vibrating element, a nozzle with two slotted slots, a guide roller, final drying drums, a price field, an emulsifying device, a sliding row and a winding mechanism with a weaving pile.

The disadvantage of this machine is that during the drying process, air flows quickly lose their pressure on the main threads when blowing, if the number of main threads per 1 cm of the filament is more than 20, and given the short duration of this effect, the destruction of the amorphous connecting film will be incomplete.

The technical result of the claimed sizing machine is to improve the quality of sizing due to the separation of the main threads directly in the area of the drying device.

The specified technical result is achieved by the fact that a sizing machine comprising a stand with warping shafts, a pulling device, an adhesive device, a drying device consisting of preliminary and final drying drums, between which there is a vibrating cylindrical element, an output pneumatic circular nozzle located under it with two guiding slotted opposite slots and a guide roller; a price field, an emulsifying device, a sliding row, a winding mechanism with a weaving pile, additionally contains two pneumatic suction inlet nozzles, the guide slots of which are funnel-shaped and are located opposite the corresponding guide slots of the output nozzle.

The air flows coming out of the output pneumatic nozzle of circular cross section encounter an obstacle in the form of main threads glued together. An amorphous connecting film will only partially collapse if the number of warp threads per 1 cm of the filling width is more than 20. This is because the jet of compressed air quickly dissipates in space (an example is the need to use confuser channels to lay the weft thread on pneumatic looms Talavashek O., Svaty V. Shuttleless looms: Translated from Czech - M .: Legprombytizdat, 1985, - 335 s, pp. 222-225) and loses its pressure.

Therefore, to maintain the force of the air flow in the inventive sizing machine, it is proposed opposite the guide slots of the output pneumatic nozzle, which is located under the vibrating cylindrical element, to position the guide slots of the input pneumatic suction nozzles. In the zone of air space between these slits, lined main threads move, which undergo intensive separation. Further, these separated threads bend around the guide roller and pass through the area of the final drying drums.

The drawing shows a flow diagram of the inventive sizing machine, which includes sequentially located along the main threads 1 rack with warping shafts 2, the first pulling device 3, adhesive device 4, pre-drying drums 5, a vibrating cylindrical element 6, the output pneumatic nozzle 7 with two guiding slots 8 for the exit of compressed air, pneumatic inlet nozzles 9 with funnel-shaped guiding slots, guide roller 10, final drying drums 11, a price field 12, an emulsifying device 13, a sliding row 14, a second pulling device 15, a winding device with a weaving pile 16.

The inlet suction pneumatic nozzles 9 are installed so that their funnel-shaped guide slots are located opposite the guide slots 8 of the output pneumatic nozzle 7, which will allow compressed air flows to pass more intensively between the main threads 1 without being scattered in space.

The sizing machine operates as follows. The main threads 1 are wound from the warp shafts 2 from the action of the first pulling device 3 and are impregnated with the dressing in the adhesive device 4. Then the pre-drying process begins by contact with the pre-drying drums 5, after which the dressing, drying, forms an amorphous bonding film between the threads.

The air flows, leaving the guide slots 8 of the pneumatic nozzle 7 of circular cross section, act on the main threads 1, penetrate into the spaces between them and thereby destroy the film bonds.

So that the forces of the air flow do not attenuate from the counteraction of the threads, and the dispersion of air jets does not occur, an air intake stream is formed into the funnel-shaped slots of the suction pneumatic nozzles 9, which allows more efficient separation. The vibrational cylindrical element 6, creating vibrational vibrations in the threads, contributes to this process.

After rounding the guide roller 10, the main threads 1 are in contact with the working surface of the drums of the final drying 11, pass through the price field 12, emulsifying device 13, dividing row 14 and are wound on a weaving pile 16.

The use of pneumatic suction nozzles can improve the quality of non-contact separation of the main threads directly in the drying process and accelerate the removal of fumes from the working area of the sizing machine.
