Technical Field

The invention relates to a spinning tool, in particular to a network device for a spinning machine to wind and lead wires.

Background

The product of network processing becomes network yarn, also called cross yarn, which utilizes compressed air flow to spray, impact and collide the filament bundle, so that each monofilament of the filament bundle is irregularly interlaced to form node yarn with good cohesion performance.

The network processing is completed through a network device, and the structure of the network device, such as an FDY main network device disclosed by the publication number CN202072847U, comprises a seat body, a nozzle chip, a nozzle upper cover and two assemblies; the middle part of the seat body is provided with a hole for installing the nozzle; grooves are arranged on two sides of the hole; the nozzle chip is provided with an air inlet and a wire guide groove which are vertical to each other; the assembly comprises a connecting piece and a snail wire guide hook; the top of the nozzle is fixedly connected with an air inlet of the nozzle chip; the nozzle upper cover is arranged on the nozzle chip; the connecting pieces of the two assembling pieces are arranged in the grooves.

The spray points are spaced, only one spray point is arranged in a certain tow length, and the cohesion performance of the tows is reduced due to the fact that the distance between two adjacent spray points is too large.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a yarn interlacer for a winding lead of a spinning machine, which improves the cohesion performance of a yarn bundle.

The technical purpose of the invention is realized by the following technical scheme: a networker for a winding lead of a spinning machine comprises a substrate and snail wire guides arranged at two ends of the substrate, wherein a main air hole is formed in the substrate, the main air hole is connected with a nozzle, an electromagnetic valve is arranged on the nozzle, a plurality of air distribution holes are formed in the substrate along the conveying direction of a filament bundle, each air distribution hole is communicated with the main air hole, a nozzle chip is correspondingly arranged on each air distribution hole, an air inlet hole corresponding to each air distribution hole is formed in each nozzle chip, a wire guide groove communicated with the air inlet hole is formed in each nozzle chip, and when the wire guide groove is used, the wire guide groove and a hook opening of each snail wire guide are located in the range of extending of the same virtual cylinder along the axis.

According to the scheme, more spraying points are adopted for spraying treatment within the same certain tow length, the cohesion performance effect is better, and it needs to be emphasized that under the condition, the strength of the sprayed air flow is the same as that of the former spraying point when only one spraying point is arranged. Of course, for better cohesion improvement, the strength of the airflow can also be increased.

Further, a recess is seted up to the base plate bottom, an embedding plate is installed in the recess, set up a mounting hole on the embedding plate, the nozzle includes a spacing portion, set up a holding tank that holds spacing portion on the embedding plate, the holding tank is seted up in the one side that is close to the recess tank bottom, the nozzle passes the cell wall of spacing portion butt holding tank behind the mounting hole, threaded connection has first bolt on the embedding plate, first bolt passes embedding plate and base plate threaded connection.

The nozzle passes the mounting hole, and the cooperation through spacing portion and holding tank makes the nozzle fixed by base plate and embedding board, and first bolt is used for the connection of base plate and embedding board, through adopting above-mentioned dismouting mode, makes things convenient for the installation and the change of whole part.

Furthermore, mounting grooves are formed in two ends of the substrate, a mounting column is fixed to the bottom of the snail wire guide hook, through holes which are radially communicated along the mounting column are formed in the mounting column, a second bolt is connected to the substrate through threads, penetrates through the through holes, is connected with the substrate through threads, and extends into the embedded plate.

So carry out spacing fixed to snail wire guide through the second bolt, the second bolt plays the fixed action to the embedding board simultaneously.

Further, every fixed closing plate that a butt base plate surface on the nozzle chip, a fixed pivot that passes the nozzle chip on the base plate, every nozzle chip corresponds a pivot, the pivot is located nozzle chip one end, a positioning bolt of nozzle chip opposite end threaded connection, positioning bolt passes the nozzle chip and stretches into in the base plate, when the nozzle chip rotates to the scope that breaks away from virtual cylinder along the axis extension, the closing plate rotates to the branch gas pocket that seals corresponding nozzle chip.

The number of the nozzle chips (namely the number of the spraying points) is selected according to needs, when the number of the nozzle chips is not needed, the nozzle chips are rotated to be separated from the range of the virtual cylinder extending along the axis, in the rotating process, the closing plate rotates together, and finally the air distribution holes are closed, so that air flow is prevented from coming out of the air distribution holes.

Furthermore, each sealing plate is provided with a butt joint hole with the same diameter as the gas distribution hole, a butt joint column capable of moving up and down is arranged in the butt joint hole, and a cover plate covering the butt joint hole is fixed on the butt joint column.

The setting of butt joint post can stretch into the branch gas pocket on the one hand, reduces branch gas pocket gas leakage probability, and on the other hand is also spacing to the closing plate for the closing plate can not rotate, also nozzle chip can not take place to rotate.

Furthermore, the cover plate and the closing plate are magnetically adsorbed.

Through the magnetic adsorption of the closing plate and the cover plate, airflow is not easy to leak from the butt joint hole.

Furthermore, a pull ring is fixed at the upper end of the cover plate.

The arrangement of the pull ring is convenient for the butt-joint column to be separated from the gas distributing hole, and the pull ring is pulled to lift.

Furthermore, a first rubber sheet is fixed on one end face of the closing plate close to the substrate, and a second rubber sheet is fixed on one end face of the covering plate close to the closing plate.

The first rubber sheet and the second rubber sheet are arranged to obtain better sealing performance.

In conclusion, the invention has the following beneficial effects: the invention can improve the cohesion performance of the wire harness by increasing the injection points in unit length under the condition of unchanged intensity of the injected air flow, and simultaneously can change the number of the injection points according to different types of wire harnesses.
