Problems solved by technology

However, due to the use of sizing agent in the molding of glass fiber, different wax-free wetting formulas will make the surface of the glass fiber have a certain degree of stickiness, and the ultra-fine glass will be placed on the electromagnetic needle of the weft feeder during weaving because of this stickiness. The fiber sticks, which brings difficulties to weft insertion, low efficiency and poor start-up, and cannot weave normally

Embodiment 1

[0022] Such as figure 1 The shown electromagnetic needle powder spraying device includes a powder spray assembly arranged above the electromagnetic needle assembly. The electromagnetic needle assembly includes a magnetic component that generates an electromagnetic field, an electromagnetic needle 12 that moves axially within the magnetic field, and a return spring 13 that drives the electromagnetic needle 12 to return axially. As shown in the figure, a coil bobbin 15 is arranged inside the shell of the electromagnetic needle assembly, and a coil 16 is arranged on the coil bobbin 15, and the coil 16 is used as a magnetic component for generating an electromagnetic field; an electromagnetic needle moving channel 14 is arranged in the electromagnetic field , the electromagnetic needle is positioned in the electromagnetic needle moving channel 14 . It should be noted that the magnetic field referred to in this scheme can be a conventional motor magnetic field, that is, the magnet...

Embodiment 2

[0025] figure 2 Shown is the second embodiment of the electromagnetic needle powder spraying device. This scheme is the same as the overall structure of the above-mentioned embodiment 1. It is also through the instantaneous change of the air pressure caused by the high-speed movement of the electromagnetic needle 12, and the powder in the powder storage chamber 21. After the talcum powder is sucked out by the powder outlet 24, it is atomized and sprayed out through the powder spraying end 14a at the lower end of the electromagnetic needle moving channel; The powder injection end 14a of 14 directly communicates, and the powder passage shown in the figure is to be made of the pipeline 26 that connects powder outlet 24 and powder injection end 14a. Adopting this structure can achieve the purpose of spraying powder on the surface of the electromagnetic needle 12. Compared with the technical solution that the powder outlet 24 communicates with the upper channel opening of the elec...

Embodiment 3

[0027] image 3 , Figure 4 Shown is the third embodiment of the electromagnetic needle powder spraying device. This scheme is the same as the overall structure of the above-mentioned embodiment 2. It is also through the instantaneous change of the air pressure caused by the high-speed movement of the electromagnetic needle 12, and the powder in the powder storage chamber 21. After the talcum powder is sucked out by the powder outlet 24, it is atomized and sprayed out from the powder spraying end 14a through the powder outlet channel formed by the pipeline 26. This solution has the advantages of the above-mentioned embodiment 2; the difference is that the powder spraying end 14a There is a powder spraying part 17 on the top, and the lower end of the powder outlet channel (that is, the pipeline 26) is connected to the powder spraying part 17; the powder spraying part is provided with a central axis hole 171, and several linear channels 172 that diverge along the circumference o...

Abstract

The invention relates to the field of knitting equipment, in particular to an electromagnetic needle powder spraying device which comprises a powder spraying assembly arranged over an electromagnetic needle assembly.The electromagnetic needle powder spraying device is characterized in that the electromagnetic needle assembly comprises an electromagnetic needle which is axially and movably arranged in an electromagnetic field; the powder spraying assembly comprises a powder storage chamber, the bottom of the powder storage chamber is provided with a powder outlet which is communicated with an electromagnetic needle moving channel arranged in the electromagnetic needle assembly, and the lower end of the electromagnetic needle moving channel serves as the powder spraying end.According to the electromagnetic needle powder spraying device, a trace amount of atomized similar talcum powder is continuously sprayed on the surface of the electromagnetic needle in the knitting process, therefore, a layer of a powder film is formed between a wax-free superfine glass fiber and the electromagnetic needle, and adhesion of the glass fiber and the electromagnetic needle is prevented.After the device is adopted, starting can be smoothly achieved, the adhesion phenomenon of the glass fiber and the electromagnetic needle almost can be completely prevented, the knitting efficiency is greatly improved, and normal application of the wax-free fine-denier glass fiber is made possible.

Description

technical field [0001] The invention relates to the field of knitting equipment, in particular to an electromagnetic needle powder spraying device. Background technique [0002] With the advancement of technology in the glass fiber weaving industry, wax-free glass fiber and ultra-fine denier glass fiber are welcomed by users. However, due to the use of sizing agent in the molding of glass fiber, different wax-free wetting formulas will make the surface of the glass fiber have a certain degree of stickiness, and the ultra-fine glass will be placed on the electromagnetic needle of the weft feeder during weaving because of this stickiness. Fiber sticks, which brings difficulty in weft insertion, low efficiency and poor start-up, and cannot weave normally. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a powder spraying device for electromagnetic needles. During the weaving process, a small amount of ...
