Problems solved by technology

[0002] In the production process of the textile industry, the control of yarn tension is a very important issue. If the yarn tension is not effectively controlled, the subsequent shedding and beating-up actions will not be implemented smoothly.
The existing yarn tension control device has poor tension consistency, small amount of yarn compensation, or the use of an electronic control device leads to large volume and high cost of the yarn tension control device, which cannot meet the problems of single yarn tension control in multi-yarn equipment.

Embodiment 1

[0014] see figure 1 , 2 The compensable mechanical yarn tension control device shown mainly includes a yarn return disc 1 with a guide eye, a manual adjustment sleeve 2, a coil spring 3, a one-way brake circlip 4, a fixed support 5, and a connecting piece 6. Bearing positioning nut 7, yarn storage tray support 8, yarn storage tray 9, bearing 10.

[0015] The yarn return disc has an extension 15 extending axially along the yarn return disc, and an axial passage 16 communicating with the radial passage is provided in the extension for the yarn to pass through. There is a radial passage 14 inside the yarn return disk 1 for the yarn to pass through. One end opening (yarn guide eye) 13 of the radial passage is on the peripheral surface of the yarn return disk, and the other end is opened at the axis of the yarn return disk. Axial channels 16 communicate with each other.

[0016] The extension part 15 of the yarn returning disc 1 and the bearing positioning nut 7 are integrally c...

Embodiment 2

[0022] see image 3 , Embodiment 2 differs from Embodiment 1 in that: a yarn guide rod 12 for changing the yarn output direction is fixed on the outside of the manual adjustment sleeve, and a yarn guide wheel 17 is provided on the yarn guide rod 12 .

[0023] The present invention mainly solves the problem that the existing yarn tension control device has poor tension consistency and small yarn compensation amount, or the yarn tension control device is large in volume and high in cost due to the use of an electric control device and cannot meet the single yarn tension control in multi-yarn equipment And other issues. Compared with the prior art, the present invention has the advantages of:

[0024] 1. The present invention has comprehensive performances such as yarn storage, continuous yarn supply, constant yarn tension, and large amount of yarn compensation; when the yarn tension is 200g±20g, the outer dimensions of the yarn return disc and the manual adjustment sleeve after...

Abstract

The invention provides a compensable mechanical yarn tension control device which has the advantages of simple and compact structure, large yarn compensation dosage, less components, easy processing, easy assembly, low cost, convenient use and effectively improved production efficiency. The compensable mechanical yarn tension control device comprises a yarn-returning disc rotatably arranged on a fixed bearing, wherein the yarn-returning disc is internally provided with a radial passage through which yarns pass; one end opening of the radial passage is positioned on the circumferential face ofthe yarn-returning disc, and the other end opening of the radial passage is positioned on the end face of the axis of the yarn-returning disc; and a manual regulating sleeve is arranged on the fixed bearing, a nest spring is arranged between the manual regulating sleeve and the yarn-returning disc, and in normal state, the nest spring can enable the yarn-returning disc to rotate clockwise or anticlockwise relative to the manual regulating sleeve.

Description

technical field [0001] The invention relates to a compensable mechanical yarn tension control device, which belongs to the technical field of textile machinery. Background technique [0002] In the production process of the textile industry, the control of the yarn tension is a very important issue. If the yarn tension is not effectively controlled, the subsequent shedding and beating-up actions will not be implemented smoothly. The existing yarn tension control device has poor tension consistency and small yarn compensation amount, or the use of an electronic control device leads to the large volume and high cost of the yarn tension control device, which cannot meet the problems of single yarn tension control in multi-yarn equipment. Contents of the invention [0003] The purpose of the present invention is to provide a compensable mechanical yarn tension control device with simple and compact structure, large amount of yarn compensation, few parts, easy processing, easy ...
