Single spindle type solid compact spinning

Abstract

The invention discloses a single spindle type solid compact spinning, and belongs to the technical field of spinning machinery. A cradle of a spinning frame is provided with a lower leather roller, and a bottom roller is arranged below the cradle and closely pressed on the lower leather roller. The compact spinning is characterized in that: the left end and the right end of the lower leather roller are provided with mounting shafts; each holding frame is provided with a moving end, an arc concave part and a handle; each two holding frames form a group, and are face-to-face arranged on the mounting shafts on the left end and the right end of the lower leather roller; the holding frames are provided with two groups of magnets; the first group of magnets are arranged on the cradle corresponding to the holding frames, and the second group of magnets are arranged on the lower roller corresponding to the holding frames; and a compact piece are arranged between two holding frames in the same group, and are seamlessly pressed on the lower roller by the magnetic attraction of the second group of magnets. The compact spinning has the advantages of simple structure, good beam concentrating effect, and regular yarn after twisted.

Description

technical field [0001] The invention relates to a textile machine, in particular to a single-spindle three-dimensional compact spinning. Background technique [0002] In the spinning process of the traditional spinning frame, after the drafted sliver leaves the front roller with a certain width and in a free state, it is immediately processed into a yarn, and a spun yarn is formed in the yarn forming area In the triangular area, because the loose fibers in the spinning triangular area cannot be well controlled, many fiber whiskers around the yarn sliver will be scattered in advance and cannot be bundled, and the scattered fibers will protrude out of the yarn because they cannot be squeezed into the yarn The "hairiness" that occurs in spinning is formed, which seriously affects the yarn quality and reduces the fiber utilization. Therefore, it is necessary to improve the conveying form of the sliver before twisting, even if the sliver is parallel, straight and closely arrange...

Problems solved by technology

For example, a compact spinning device with patent No. 03228410.1 is provided with an air suction pipe with two ends fixed on two adjacent roller seats with air suction port and exhaust port, which is set outside the air suction pipe and corresponds to the position of the air suction port. The cohesive sleeve with a condensation groove in the circumferential direction of the cohesive sleeve, the tension device stuck in the cohesive sleeve, the air-permeable conveying ring and the transmission pressure device set on the cohesive sleeve, the compact spinning device can make the fiber bundle output by the front roller Under the action of negative pressure generated by the exhaust system, it is adsorbed on the air-permeable conveying ring, and under the action of the pressurized transmission device and the air-permeable conveying ring, the fiber bundle is tightened and straightened to achieve twisting into yarn. The yarn device can better solve the original "hairiness" problem and improve the yarn quality, but there are also some shortcomings, such as complex structure and high production cost; and the compact spinning device and the roller are driven by different power devices. It is easy to cause the speed of the compact spinning device to be out of sync with the speed of the rollers, resulting in yarn blocking and yarn breakage, which cannot eliminate the twisting triangle and affect the quality of the yarn
