Problems solved by technology

The disadvantage of this connection method is that there is a certain gap between the winding bobbin and the bobbin shaft, so there will be a virtual holding state during high-speed operation, and the product quality of the roving cannot be guaranteed.

Embodiment Construction

[0014] A method for connecting a bobbin shaft and a bobbin according to the present invention, the bobbin length is 445mm, the outer diameter is φ45mm, the inner diameter is φ36-φ37mm (free tolerance), and a holding section (φ25mm or φ22mm) is added to the head . The bobbin shaft 1 is fixed on the lower rib 8, the bobbin 2 is installed on the bobbin shaft 1 through the bobbin sleeve 3, and the maximum outer diameter of the bobbin sleeve 3 is φ36mm. The bottom of the bobbin 2 is driven to rotate by the starting block 5 installed on the synchronous pulley 9, and the bobbin 2 and the bobbin sleeve 3 rotate on the bobbin shaft 1 through two bearings 6, including the following steps:

[0015] A) Screw the bobbin shaft 1 on the lower rib 8 with a nut; the bobbin shaft 1 is stationary, and the outer diameter of the bobbin shaft 1 is φ25mm.

[0016] B) The starting block 5 is installed on the synchronous belt pulley 9; when rotating, the transmission gear drives the synchronous belt ...

Abstract

This invention discloses a connecting method of bobbin and the bobbin axis in the flyer frame. Bobbin axis is fixed on the down spindle bearing plate; bobbin is fixed on the bobbin axis by bobbin axle-box. The base of the bobbin is driven to rotation by the starting mode fixed on the synchronous pulley, the bobbin axis is stationary, and the bobbin and the bobbin axle-box is rotated on the bobbin axis by bearing. Several spring laminations fitted the bobbin axle-box and bobbin axis by the form of circular arc contact. The bobbin axle-box and bobbin axis can fit closely in the high speed running; it can assure the quality of the roving. This invention is acceptable for the flyer frame in the cotton mill.

Description

1. Technical field [0001] The invention relates to a roving frame in a textile machine, in particular to a method for connecting a winding bobbin of the roving frame to a bobbin shaft. 2. Background technology [0002] At present, the winding bobbins of the roving frames in the existing domestic cotton spinning mills all adopt uniform standard special bobbins. Add a holding section (φ25mm or φ22mm). When working, the middle rod (φ25mm or φ22mm) of the flyer (suspended spindle) is slowly inserted into place from the head section of the winding bobbin. The holding section of the bobbin is slidingly fitted and held with the middle rod of the flyer (suspended spindle). During normal operation, the starting block groove at the tail section of the winding bobbin is driven by the starting block to rotate. At this time, the head section of the winding bobbin and the middle rod (φ25mm or φ22mm) of the flyer (suspended spindle) are gripped by sliding fit. The disadvantage of this c...
