Chain hoisting mechanism of coarse spinner

Abstract

The invention discloses a chain hoisting mechanism of a coarse spinner. The chain hoisting mechanism comprises chain pieces, cover plates, springs and bobbin hangers, wherein the upper portion of each bobbin hanger penetrates through a center hole of each corresponding chain piece and supports a boss of the inner wall of each corresponding center hole, the top of each center hole is sealed by each corresponding cover plate, the two ends of each spring are connected with the top end of each corresponding bobbin hanger and each corresponding cover plate respectively, the springs is compression springs, the push force of the compression springs on the bobbin hangers is larger than force needed for triggering the bobbin hangers to move, and due to the flexible installation mode of the springs between the bobbin hangers and the chain pieces, the bobbin hangers and the chain pieces can have certain moving space in position. On one hand, the probability that the bobbin hangers are cracked up is greatly reduced, on the other hand, even if at different heights, the bobbin hangers can be triggered to move when stressed in the same degree, the whole device is convenient and easy to install and detach, efficiency is greatly improved, and industrial large-scale production and follow-up maintenance are facilitated.

Description

technical field [0001] The invention relates to a roving frame, in particular to a chain sheet structure of the roving frame. Background technique [0002] The automatic doffing roving frames currently on the market basically adopt the structure of rails and chains. Among them, the rails mainly provide support for the chain and determine the route of the chain, and the basic function of the chain is to convey empty bobbins and full bobbins. The way to realize it is to realize walking in a predetermined direction in the track under the drive of a motor or manpower. And the chain must have the process of hanging up or taking off the bobbin before conveying the empty bobbin or the full bobbin, and this process relies on the relative movement between the bobbin holder of the machine itself and the chain to realize. [0003] At present, the chain forms used by various manufacturers are not the same, and most of them use hanging spindles. The hanging spindles are fixed on the cha...

Problems solved by technology

[0004] For a single hanging spindle and bobbin, the above actions are easy to realize, but for the whole roving frame, it is necessary to realize the high consistency of the bobbins of the whole car if the hanging and unloading actions of hundreds of bobbins are to be realized at the same time. Higher requirements are put forward, otherwise it is easy to happen that some hanging spindles cannot be pushed in place and cannot realize the opening or closing action, or some hanging spindles are pushed too far and are damaged. This is the problem that the whole machine will face when picking and placing bobbins.
