Elastic disc type compact spinning apparatus

Abstract

The invention discloses an elastic disk-sheet compact spinning device including the lower belt roller set on the cocket centring of spinning machine, the lower roller installed on the cocket centring lower and matched with the lower belt roller, the fixed seat is connected with the lower belt roller which is set with the upper revolving solid which is connected with the lower revolving solid is also installed on the fixing seat; the magnetic switch is installed on the cocket centring to control the fixing seat. The invention can improve the fiber transformation state before adding twist and remove the triangular space at the lower roller outlet, also it can decrease the filoplume in spinning process to improve the yarn quality; the whole process is with the down roller and winding spindle in-phase to avoid the yarn block and break.

Description

technical field [0001] The invention relates to a textile machine, in particular to an elastic disk type compact spinning device applied to a spinning frame. 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 slive...

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

The twisting triangle cannot be eliminated and the yarn quality will be affected
