Problems solved by technology

However, the traction effect of the yarn-drawing mechanism of the existing roving frame is not good, which is reflected in the fact that when the existing yarn-drawing mechanism pulls the fibers, the fibers are relatively dispersed and the degree of gathering is revealed; Roving
In addition, the roller shafts in the current yarn delivery mechanism often generate high temperature against the roller, which will damage the fiber surface

Embodiment Construction

[0012] The preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0013] like Figure 1~4 A roving frame shown includes a frame 1, a discharge barrel 2 and a yarn receiving spindle 3 arranged on the frame 1, and a yarn rubbing mechanism and a yarn drawing mechanism arranged between the discharge barrel 2 and the yarn receiving spindle 3. mechanism.

[0014] The yarn pulling mechanism includes a fiber guide frame 4, a limit closing sleeve 5 and a fiber pulling assembly 6 between the yarn twisting mechanism and the discharge barrel 2, and a yarn guide assembly 7 between the yarn twisting mechanism and the yarn receiving spindle 3. . The fiber guide frame 4 is located above the fiber pulling assembly 6. The fiber guide frame 4 is provided with a guide roller shaft 41, and a plurality of partition plates 42 arranged along the axial gap of the guide roller shaft 41. Each fiber guide groove is used t...

Abstract

The invention relates to the field of textile processing, and relates to a yarn guiding mechanism on a roving frame. The yarn guide assembly between the mechanism and the yarn receiving spindle; the limiting closing sleeve is located upstream of the fiber traction assembly, the limiting closing sleeve is trumpet-shaped, and the outlet port diameter of the limiting closing sleeve is smaller than the inlet port diameter; the fiber drawing assembly includes Multiple driving roller shafts and multiple driven roller shafts, the multiple driving roller shafts are arranged in gaps along the yarn feeding direction, and the multiple driving roller shafts are arranged in parallel, and the multiple driven roller shafts are arranged at intervals between the multiple driving roller shafts Above the gap, each driven roller shaft is attached to two adjacent driving roller shafts for grinding; the yarn drawing mechanism has a novel structure, which can guide the fibers to gather when pulling the fibers, so that it is easy to obtain a high-density roving.

Description

technical field [0001] The invention relates to the field of textile processing, in particular to a yarn drawing mechanism on a roving frame. Background technique [0002] A roving frame is a spinning machine that turns fiber strips into rovings. The roving frame mainly includes the yarn pulling mechanism to draw the fibers, and the fibers are twisted into rovings through the yarn twisting mechanism. However, the pulling effect of the yarn pulling mechanism of the existing roving frame is not good, which is reflected in the fact that when the existing yarn pulling mechanism pulls the fibers, the fibers are relatively scattered and the degree of aggregation is complete; in this way, it is difficult for the yarn winding mechanism to twist the fibers into a relatively tight shape. Roving. In addition, the rollers in the current yarn take-off mechanism often generate high temperature, which will damage the fiber surface. SUMMARY OF THE INVENTION [0003] In order to solve t...
