Cotton-feeding cubing-roll device of cover plate type carding machine

Abstract

The invention provides a cotton-feeding cubing-roll device for a cover plate type carding machine, comprising a roller (12), a fiber feeding board (11), a cubing roll (13) and a cubing-roll housing plate (16), wherein the fiber feeding board (11) is arranged under the roller (12); the cubing roll (13) is arranged on one side of the roller; the cubing-roll housing plate (16) is arranged above the roller (13); a mote knife (14) and a small screen (15) are arranged under the cubing roll (13); the mote knife (14) is arranged on one side of the cubing roll (13) close to the roller (12); and a wrapping angle a of the small screen (15) is between 109 and 140 degrees. The cotton-feeding cubing-roll device for the cover plate type carding machine can effectively improve the utilization rate of fibrilia, and ensure even slivering, good quality of final yarn, and stabilize the blending ratio with cotton and other fibers.

Description

technical field [0001] The invention relates to a cotton-feeding licker-in device for a flat carding machine, in particular to a cotton-feeding licker-in device for a flat carding machine used for carding hemp fibers, especially jute fibers. Background technique [0002] When spinning fibers, it is necessary to use a carding machine to card the above-mentioned fibers. For finer fibers such as cotton fibers, chemical fibers and hemp fibers, a flat carding machine is usually used. The flat carding machine usually includes The cotton feeding licker-in roller device, carding device, stripping device, sliver forming device, etc. arranged in sequence in the feeding direction, the cotton feeding licker-in roller device includes a roller, a fiber feeding plate arranged under the roller and a The licker-in roller on one side of the roller, the licker-in roller cover plate is arranged above the licker-in roller, and the dust removal knife and small drain bottom are arranged below, the...

Problems solved by technology

And there is no carding machine specially used for hemp fiber spinning at present. When carrying out hemp fiber spinning, the enveloping angle a of chemical fiber spinning is usually selected for use as a cover plate carding machine with a small leak bottom of 101 °. The bottom cladding angle is relatively large, so that the second trash area is relatively small, so that the trash in the second trash area can be relatively reduced, but because hemp fibers, especially jute and hemp fibers are thicker than other fibers such as chemical fibers Short, brittle and easy to break, the size of the second trash area is still larger than that of the short fluff of the broken hemp fiber, and a large part of the broken hemp fiber falls into the second trash area, resulting in the utilization of the hemp fiber The utilization rate of hemp fiber is reduced (the utilization rate of hemp fiber is only 50-55%). At the same time, due to the large number of impurities in the short fleece, the uniformity of the strips is affected. When the hemp fiber is blended with other fibers, it will also make the hemp fiber The blending ratio of fibers is difficult to control, which affects the quality
