Network yarn forming device

Abstract

The invention relates to an interlacing yarn forming device. The interlacing yarn forming device comprises yarn tensioning devices and an air injection device, wherein the two yarn tensioning devices correspond to one air injection device; each yarn tensioning device comprises a support, a fixing groove, a movable device and an enamel clamping piece, the fixing groove is longitudinally formed in the support, and an opening is formed in the front side face of the fixing groove; the movable device comprises a movable rod, a supporting rod, a guide wire, a pulley and an article containing base, the movable rod is arranged on the inner wall face of one side wall of the fixing groove, the upper end of the movable rod extends out of the fixing groove, one end of the supporting rod is fixed to the upper end of the movable rod, one end of the guide wire is fixed to the other end of the supporting rod, the other end of the guide wire winds through the pulley and is connected with the article containing base, the clamping piece comprises two or more bent grabbing parts same in length and a connecting rod, and the air injection device comprises an air stream pipe into which high-pressure air stream is fed, a plurality of branch pipes distributed on the air stream pipe, a jet nozzle, a locking device and a spring. The interlacing yarn forming device has the advantages of being small in amount of consumed air, favorable for forming interlacing joints of interlacing yarn, convenient and fast to operate and the like.

Description

technical field [0001] The invention relates to a network yarn forming device. Background technique [0002] The stretched two yarns are bonded to each other at intervals under the blowing and twisting action of the high-pressure airflow to form filaments with periodic network knots, which are called network yarns. On the one hand, in the production process of network yarn, the air injection device used to eject high-pressure airflow, especially the nozzle of the air injection device is the key part of the network yarn forming process, and its performance determines the quality and air consumption of the finished yarn And the ease of operation and many other aspects; on the other hand, because the yarn just coming out of the bobbin is often fluffy, rough and curled, if two fluffy and curled yarns are directly entered into the air jet used to spray high-pressure air In the device, it will not be well bonded, and the entanglement effect is not good, and the distribution of en...

On the one hand, in the production process of network yarn, the air injection device used to eject high-pressure airflow, especially the nozzle of the air injection device is the key part of the network yarn forming process, and its performance determines the quality and air consumption of the finished yarn And the ease of operation and many other aspects; on the other hand, because the yarn just coming out of the bobbin is often fluffy, rough and curled, if two fluffy and curled yarns are directly entered into the air jet used to spray high-pressure air In the device, it will not be well bonded, and the entanglement effect is not good, and the distribution of entanglement knots is uneven; The integrated network yarn forming device makes the formed network yarn have good entanglement effect, moderate length of entanglement knots, uniform distribution of entanglement knots and low detanglement rate. In addition, the network yarn forming device should also have the characteristics of low air consumption
