Yarn pressing device for covered yarn and using method thereof

Abstract

The invention discloses a yarn pressing device for covered yarn. The yarn pressing device comprises a yarn pressing frame, a yarn pressing device body is installed on the yarn pressing frame, the yarnpressing device body comprises a yarn pressing barrel, a yarn outlet is formed in one side of the yarn pressing barrel, a yarn pressing baffle is arranged at the yarn outlet, a plurality of fixing sleeves are arranged on the periphery of the yarn pressing baffle, and the fixing sleeves are movably connected with a fixing valve; and one side of the fixing valve is fixedly connected to one side ofthe yarn pressing barrel, a pushing device is arranged on the other side of the yarn pressing barrel, the pushing device comprises a pushing rod, a pushing plate is installed at the front end of the pushing rod, and an air cylinder is arranged at the rear end of the pushing rod. According to the yarn pressing device for the covered yarn, the extruded pressure of the covered yarn is guaranteed through the yarn pressing device, the dyeing condition of each drum of covered yarn in a high-pressure dyeing machine in the later period is guaranteed according to the extruded pressure, the dyeing uniformity of the covered yarn is higher, chromatic aberration is avoided, and meanwhile the dyeing amount of the same high-pressure dyeing agent is increased.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a yarn pressing device for covering yarn and a use method thereof. Background technique [0002] During the dyeing process of the bread yarn, the bread yarn needs to be squeezed due to the dyeing effect. At the same time, in order to ensure that there is no color difference in the dyeing, manual extrusion is used, especially for the samples that the company needs in the early stage. According to the requirements of the samples Different dyes need to be dyed in a high-pressure dyeing tank to ensure that the dyeing effect is uniform and there is no color difference. In the process of artificial polar extrusion, the extrusion effect is different due to the uncontrollable force, and the dyeing is also different due to the different demand for samples. Similarly, in order to ensure that it is completed in a high-pressure dyeing vat, it is necessary to increase the extrusion effect so...

[0002] During the dyeing process of the bread yarn, the bread yarn needs to be squeezed due to the dyeing effect. At the same time, in order to ensure that there is no color difference in the dyeing, manual extrusion is used, especially for the samples that the company needs in the early stage. According to the requirements of the samples Different dyes need to be dyed in a high-pressure dyeing tank to ensure that the dyeing effect is uniform and there is no color difference. In the process of artificial polar extrusion, the extrusion effect is different due to the uncontrollable force, and the dyeing is also different due to the different demand for samples. Similarly, in order to ensure that it is completed in a high-pressure dyeing vat, it is necessary to increase the extrusion effect so as to improve the efficiency of a single dyeing vat and ensure the dyeing effect. At present, there is no suitable extrusion equipment. At the same time, manual extrusion causes different strengths and reduces the amount of dyeing. , the dyeing is uneven, and there is an urgent need for a device that can improve the extrusion effect to operate
