Abstract

The invention relates to an integrated composite spinning device of a ring spinning frame. The device comprises a special-shaped tube, a grid ring, an integrated composite roller and a tension supporting mechanism; negative pressure integrated composite tubes are positioned at two ends of a front tube wall on one side of a fiber whisker outlet line and provided with two extended roller supporting seats with closed peripheries, tension supporting seats are arranged below the two roller supporting seats, and the negative pressure integrated composite tubes are provided with more than two positioning surfaces; the tension supporting mechanism comprises a tension supporting frame and two positioning spring plates; the tension supporting frame comprises a tension rod and more than three limit sliding seats arranged transversely at intervals along the tension rod; the limit sliding seats are propped on the lower part of the tension rod by adjusting springs, and the bottom of each limit sliding seat is provided with a stop block; and the connecting surfaces of the two positioning spring plates are connected with the two tension supporting seats respectively, and the adjusting and installation surfaces of the two positioning spring plates are in pressing connection with two ends of the tension rod respectively. The device can improve the assembly precision, adjust the axial position of the grid ring in time and conveniently adjust the tension of the grid ring.

Description

technical field

[0001] The invention relates to a compact spinning device of a ring spinning frame, which belongs to the field of pneumatic gathering devices of compact spinning machines. 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. It is composed of tensioning mechanism, etc. There are multiple airflow guide grooves on the tube wall of the guide surface of the negative pressure accumulation tube, and the surface of the grid ring is densely covered with air holes. On the guide groove, each airflow guide groove corresponds to a fiber whisker. Under the action of the negative pressure airflow in the negative pressure gathering tube, the hairiness of the fiber whiskers is gathered on the airflow guide groove while being transported by the rotation of the grid ring. And effectively reduce the spinni...

Embodiment Construction

[0029] See Figure 1-14 As shown, the compact spinning device of the ring spinning frame of the present invention includes a special-shaped tube 1, a grid ring 3, a compact roller 2 and a tension support mechanism. The special-shaped pipe 1 of the present invention includes a negative pressure accumulation pipe 1-1 and an end plug 5 sealed and installed at the gap 1-9 at both ends of the negative pressure accumulation pipe 1-1. The end plug 5 at the end keeps the negative pressure airflow of the negative pressure collecting pipe 1-1 from leaking, and the pipe wall of the negative pressure collecting pipe 1-1 along the guide surface is provided with at least one suction joint 4 and three suction joints communicating with the negative pressure chamber. There are more than two airflow guide grooves 1-4, and the suction joint 4 is sealed and fixed at the suction hole 1-5 of the negative pressure accumulation pipe 1-1. Inhaled into the negative pressure accumulation pipe 1-1, one ...
