Yarn feeding device of spinning machine

Abstract

The invention discloses a yarn feeding device of a spinning machine, and belongs to the technical field of chemical fiber textile equipment. The spinning machine comprises a spinning box arranged at the upper part of a rack wallboard, the spinning box is provided with a plurality of spinning positions, each spinning position corresponds to a channel and a tow oiling and guiding mechanism, the channels are fixed to an upper platform of the rack wallboard, the tow oiling and guiding mechanisms are arranged on the rack wallboard, and a pre-stretching mechanism is arranged on a terrace. The yarn feeding device comprises automatic channel closing mechanisms, an automatic yarn sucking mechanical arm and a tow automatic cutting mechanism, the number of the automatic channel closing mechanisms isequal to that of the channels, the automatic channel closing mechanisms are in cooperative connection with the lower portions of the channels, the automatic yarn sucking mechanical arm is arranged onthe terrace, the automatic yarn sucking mechanical arm sucks tows led out from the automatic channel closing mechanisms and pulls the sucked tows to the tow automatic cutting mechanism under the statethat the sucked tows pass through the tow oiling and guiding mechanisms, and the tow automatic cutting mechanism is arranged on the rack wallboard. The requirement for mechanical automatic yarn feeding is met, labor force is saved, the operation intensity is reduced, and the safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber textile equipment, and in particular relates to a head raising device of a spinning machine. Background technique [0002] As is known in the industry, the fine melt extruded from the spinneret of the spinning assembly of the spinning box of the spinning machine needs to be cooled, oiled, plied, etc. after being formed into fibers, and finally enters the spinning tube and puts it into the follow-up process. Processes such as stretching and packing. In the prior art, after the staple fiber is spun into fibers, the on-line operator (commonly referred to as "spinner") usually holds a suction gun (the suction gun is connected with a negative pressure generating device by a pipeline) to extract the fiber from the spinning position. The tow in the tunnel is led through the oiling roller, godet roller, shredding guide roller and tow cutting mechanism in sequence, and then is drawn into the silk d...

AI Technical Summary

Problems solved by technology

Since the number of single fibers ejected from the spinneret is hundreds or thousands or more, and because the total density of the filaments in the spinning position (customarily called "spinning position") is high (the filaments are thick), it is also due to the There are multiple spinning positions in a spinning machine, so there are at least two shortcomings in the use of manual head lifting: first, it requires a lot of manpower and the work intensity of online operators is high; Being entangled by tow or touched by rollers may cause accidents

[0003] In the published Chinese patent literature, it can be seen that all the technical information related to head raising is typical, such as "a one-step head raising device for spinning high-speed winding machine" recommended by CN105603552B. The technical effect recorded in paragraph 1, but due to the manual lifting of the head (paragraph 0021 of the manual), there are also the above-mentioned deficiencies

In particular, since the patent is aimed at the head-up of the winding machine, there is no technical inspiration for the automatic head-up of the melt-spun staple fiber, that is, the automatic head-up of the spinning machine
