Side-pull type spindle

Abstract

The invention relates to the technical field of textile machines, in particular to a side-pull type spindle in textile machine components. The spindle solves the problems that when an existing spindleis switched between a working state and a non-working state, the positioning operation through backers is not accurate, the existing spindle is prone to be damaged, and a spindle blade cannot automatically stop rotating in a non-working state. According to the scheme, a position-adjustable fixing sleeve is arranged on a circular shaft upright post of the spindle in a sleeving manner, a positioning elastic sheet is fixed on a spindle seat, the positioning elastic sheet is provided with a first elastic portion extending to the outer wall of the fixing sleeve, the first elastic portion is provided with a positioning projection or a positioning steel ball, and a working positioning hole and a non-working positioning hole are formed in the fixing sleeve; when the positioning protrusion or thepositioning steel ball meshes with the working positioning hole, the spindle seat is in a working position; when the positioning protrusion or the positioning steel ball meshes with the non-working positioning hole, the spindle seat is in a non-working position; and a brake elastic sheet is fixed on the fixing sleeve, the brake elastic sheet is provided with a second elastic portion extending outwards, a friction plate is fixed on the second elastic portion, and the friction plate makes contact with the spindle blade when the spindle seat is in the non-working position.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a side-pull spindle in the components of the textile machinery. Background technique [0002] Spindle is an important part of textile machinery. It is used to place the yarn bobbin for yarn feeding. The spindle rod on which the yarn bobbin is installed on the spindle is driven by the drive belt of the machine to rotate. Due to the need to replace the yarn bobbin and insert new yarn, the spindle rod It needs to be disengaged from the driving belt, so the spindle bar needs to be able to swing and disengage or fall off sideways. Chinese patent publication No. CN209836416U discloses a side-pull hollow ingot assembly, as attached figure 1 As shown in the figure, there is a circular shaft column fixed on the dragon tendon of the machine, a spindle seat is arranged on the circular shaft column for swinging, the spindle bar is rotated on the spindle seat, and a spring-loaded sp...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the spindle seat and the spindle have two positions, working and non-working, correspondingly, two positioning structures are required. In the prior art, two backings are generally set on the machine dragon tendon, and the spindle seat is positioned after hitting the backing. The disadvantages of this positioning method are: 1. It is easy to damage the spindle seat; 2. The positioning position will shift after long-term use

[0004] Even so, the existing positioning method still belongs to a simple blocking method of positioning, and the spindle bar will continue to rotate due to inertia from the working state to the non-working state. The existing technology relies on manual contact to stop the rotation. , which also brings inconvenience to the operation
