Abstract

The invention relates to the field of producing chemical yarns - to the instrumentation of the operation of separating the working fluid from the moving yarn during its forming or finishing and improves the reliability of the automatic threading of the yarn during its forming. This goal is achieved by the fact that a device for separating a liquid from a moving thread, comprising a housing with nozzles for supplying and discharging a liquid, a thread-carrying tube in the form of a spring, a drainage tube, additionally contains a thread-spring compressing unit at the time of threading. In addition, the housing additionally has a cavity and a piston mounted inside it. The cavity is connected to the compressed air supply channel, and the piston is mounted on the liquid supply nozzle. 1 il.

WITH

The invention relates to the production of chemical fibers, namely, devices for separating liquid from a moving yarn.

The purpose of the invention is to increase the reliability of threading.

The invention is illustrated in graphic material, where;

The drawing shows the device section.

The device for separating the liquid from the moving thread consists of a thread-conducting tube 1, made in the form of a spring and located inside the channel 2 for the thread-conducting tube. The channel is located inside the housing 3, to which the inlet 4 and the outlet 5 are attached. Channel 2 in the upper part has a drainage groove 6, and in the lower part - holes 7 for draining the separated liquid. In the upper part of the drainage groove there is a drainage tube 8. In the housing 3 there is a means for compressing the thread-conducting spring, consisting of a piston 9 mounted on the nozzle 4. The housing 3 contains an additional cavity in which there are a piston 9 and an opening 10 which is connected with valve and tap 11 for supplying compressed air. In the lower part of the housing 3 there is an opening 12 for draining the separated liquid. In the lower part, the thread pipe spring 10 is rigidly connected to the tube connected to the outlet pipe 4.

 The device works as follows.

The valve 11 of the device, which is installed directly after the forming tube or the tube with the finishing liquid, is open. Thus, the thread guide spring 1 is compressed by means of a piston 9, driven by compressed air flowing through valve 11, to form a continuous channel having inlet and outlet respectively 4 and 5 outlet. A precipitation bath or finishing liquid enters the nozzle 4, and as the thread-conducting spring is in a compressed state, the flow of fluid passes unhindered through channel 1, entrains the thread, which is fed for further processing. The creation of a flat channel due to the compression of the spring ensures the unimpeded passage of the thread through the device at the time of refilling, eliminating the possibility of thread driving the threading tube. The valve 11 is closed. Through the tap, air escapes from the cavity in front of the pistol 9 and the piston. under the action of the elastic force of the spring I returns to its original position. The separated liquid, as it moves in the thread-conducting tube 1, separates from the filament and flows out through the spring gaps in uniform flows, which pass through the openings 7 in channel 2 to the lower part of the body 3.
