SU1601243A1 - Apparatus for sizing yarn - Google Patents

Abstract

The invention relates to the textile industry, namely, weaving, and allows the tension of the yarn layers to be leveled during sizing. The device contains a null shaft, inlet and outlet rolls, a bath for the processing liquid, an immersion roll placed in it and installed between it and rolls tangentially to their forming guides. On the guides, which are spring-loaded to the rolling rollers, rollers are placed with the possibility of reciprocating movement on them for dividing the yarn into layers. EFFECT: obtaining froth from sanded yarn with uniform density. 1 hp f-ly, 2 ill.

Description

The invention relates to the textile industry, in particular to weaving, and can be used for sizing basic yarns or for liquid processing of textile materials and films.

The purpose of the invention is to equalize the tension of yarn layers and expand technological capabilities.

Figure 1 shows the flow sheet of the device, in Figure 2, also, top view.

The device contains a thin shaft 1, an input 2 and an output 3 rolling rollers, a plunging shaft 4 placed in a bath 5 for the processing liquid, rollers 6 and 7 for dividing yarn 8 into layers 9 and 10. The rollers are fixedly mounted relative to their axes on the sliders 11 three-link rocker mechanisms, also containing guides 12 and 13. mounted tangentially to the generatrix of the immersion 4 and the corresponding erratic

rollers 2 and 3, and bars 14, hingedly connected with sliders. The rollers 6 and 7 are placed on the guides 12 and 13 with the possibility of reciprocating relative to them. The springs 15 are mounted on the axles of the rolling rollers 2 and 3 and press the guides 12 and 13 to the immersion shaft 4. At the outlet of the bath are the driving squeezing shafts 16 with the clamping shafts 17 and 18. The mounting rings 19 are fixed to the axles of the idle rollers and regulate the force of pressing the guides 12 and 13 to the nylon or fluoroplastic sleeves 21 with a groove rotating freely on the axes of the submersible shaft. The diameters of the rolling rollers and the submersible shaft are equal to each other. The angles formed by layers 9 and 10 with an equal number of filaments in each with respect to the line AB are equal to each other (t y.).

The device works as follows.

In case of liquid treatment of various yarns, the immersion shaft 4 in the bath 5 is supplied to a certain depth into the treatment liquid by means of a pneumatic cylinder or a screw transmission, and rises due to the elasticity of the compression spring of the pneumatic cylinder {not shown). : The main yarns (yarns) 8 with one layer of the flow through the pulley shaft 1, the inlet | recurrent roller 2, then in the processing solution with the roller 6 the threads are separated into two layers 9 and 10 and joined at the immersion shaft 4. Pass the immersing the shaft 4, the base yits are again divided into two layers by a second roller 7, joined at the exit from the treatment fluid on the output roll 3, then squeeze-: shafts 16, first in one layer, and then with the help of pressure rolls 17 and 18 divided into two layers.

When the submersible shaft 4 is lowered or raised, the rollers 6 and 7 mounted 1 on the axles of the sliders 11 pivotally connected to the rods 14 move. Along the guides {12 and 13, the angles are equal.

 Moving the rollers b and 7 along the guides allows sizing of the yarn of different linear density.

The proposed device provides an equalization of the density of the sanding yarn when winding on with a simultaneous reduction of the breakage of the yarn during sizing and weaving.
