Description

Improve knitting wool net segmenting device of yarn evenness

Technical Field

The utility model relates to the field of cashmere carding equipment, in particular to a wool net cutting device for improving yarn evenness.

Background

Cashmere products are clothing textile materials that are well received by consumers. Cashmere yarns need to be carded by cashmere carding equipment during spinning, generally speaking, the more uniform the yarn levelness of the cashmere yarns is, the more guaranteed the quality of cashmere products is.

The head part of the traditional cashmere carding equipment, namely a carding machine, is a key mechanism of a cashmere carding device, cashmere fibers are carded into single fiber shapes on a carding part, then a wool net is output, and then the single fiber shapes are cut into wool tops on the carding machine and twisted into roving. The result of the division of the fleece into strands will directly affect the evenness of the roving, i.e. the structure and state of the strand machine is of great importance for the evenness of the roving.

Traditional woolen net segmenting device often adopts many root systems belt silk structure, and the route of belt silk is comparatively multidirectional, and the radical of its belt silk is exactly the strip radical that goes out of wool card. The main purpose of the wool net cutting device is to divide the cashmere fibers into uniform strips after carding through the cut wool net, and therefore strict requirements are put forward for the wool net cutting device, namely the tension of each belt thread needs to be kept uniform when the cut wool net works. If the tension of the belt threads is inconsistent, the cashmere fibers held by the belt threads with large tension are more, the wool tops cut by the belt threads are wider, and on the contrary, the wool tops are narrower, so that the uneven tension of the belt threads can cause uneven cutting of the wool net, and uneven yarn evenness and uneven single ends can be caused, and the belt threads with the multi-strip belt thread structure generally have more than 100, more than one belt thread, and the tension of the belt threads is difficult to be uniform. Therefore, how to stabilize the tension of the belt yarns in the carding device to be uniform and improve the evenness rate of the yarns is always a key research object of researchers.

In short, the multi-belt-yarn structure of the traditional woolen-net dividing device has the disadvantages of large number of required belt yarns, complicated structure and difficulty in uniform tension, so that yarn evenness is relatively difficult to control or improve.
