Integrated profile tube of compact spinning device in ring spinning frame

Abstract

The invention relates to an integrated profile tube of a compact spinning device in a ring spinning frame, which comprises a negative pressure compact tube and two end plugs, wherein the wall of the negative pressure compact tube along a guide surface is provided with at least one suction hole communicated with a negative pressure cavity and more than three airflow guide slots; two end parts of the front pipe wall of the negative pressure compact tube at a fiber rod outlet line side are provided with two Roller supporting seats which are respectively provided with an axle hole with the same axis; a tension supporting seat is also arranged below the two Roller supporting seats, and a mounting hole is arranged on the tension supporting seat; and the negative pressure compact tube is provided with more than two positioning surfaces. In the invention, compact Rollers and tension rods are simultaneously arranged on the negative pressure compact tube, which improves the assembly precision and the yarn quality of the compact device.

Description

technical field [0001] The invention relates to an integrated special-shaped tube of a compact spinning device in a ring spinning frame, and belongs to the field of pneumatic compacting devices of a compact spinning machine. Background technique [0002] In order to eliminate the spinning triangle area in the compact spinning machine, a negative pressure pneumatic gathering device for fiber strand aggregation is added downstream of the main draft. There are multiple airflow guide grooves on the pipe wall of the guide surface of the negative pressure accumulation tube, and the surface of the mesh ring is densely covered with air holes. The multiple mesh rings are respectively set on the airflow guide grooves of the negative pressure accumulation pipe. Make each airflow guiding groove correspond to a fiber whisker. Under the action of negative pressure airflow in the negative pressure collecting tube, the hairiness of the fiber whiskers is gathered on the airflow guiding groov...

AI Technical Summary

Problems solved by technology

The currently disclosed negative pressure accumulation pipe is provided with a horizontal installation groove on one side of the negative pressure accumulation pipe, and the two ends of the installation groove are bearing holes. On the shaft hole of the opening, there is a tension bracket installation groove for installing the tension mechanism on the negative pressure accumulation pipe. The tension mechanism that plays the role of tension support is mainly composed of tension brackets, springs and tension rods, and each tension bracket corresponding to each air flow guide groove is inserted in the tension bracket installation groove, and the lower part of the tension rod of each tension bracket is set. There is a spring, and the tension of the grid circle is adjusted by the spring, but the tension mechanism of this structure is installed on the back of the accumulating roller and is basically placed close to the level. After flying flowers and dust fall, it is easy to cause flower accumulation at the tension support. The tension support after the accumulation of flowers will easily cause the grid circle to run out of the control range of the tension support, so that the grid circle will deviate, and the fiber whiskers cannot quickly enter the airflow guide groove. position, the fiber strands can only pass through part of the airflow channel, so the fiber strands passing through the pneumatic gathering device cannot fully achieve the required yarn hairiness and strength

On the other hand, since the installation groove for installing the accumulating roller is not a fully enclosed structure in the circumferential direction, the assembly position and running accuracy of the accumulating roller and the negative pressure accumulating pipe are not easy to maintain, so it is impossible to ensure that the fiber strands after drafting and accumulating are consistent in the floating area. performance and accuracy, resulting in fluctuations in yarn hairiness and strength between spindles
