Description

Roving frame forming lifting device Technical Field The utility model relates to the technical field of roving frames, in particular to a forming lifting device of a roving frame. Background After initial processing, the fiber becomes a wool top with longer length and relatively uniform thickness, and then is twisted into thinner roving through a roving frame, and then is tightly and uniformly wound outside the bobbin, so that the roving is conveniently stored or is conveniently and smoothly fed when being processed into spun yarn later. After the roving of outside rolling of spool reaches a certain amount, need control the lift platform and descend for the top and the spindle blade separation of spool, then take off the spool and change the spool in the sky, in this in-process, can form high coaxial relation with the spindle blade after placing for the guarantee spool, generally set up the integral key shaft on the lift platform and set up rather than assorted spline groove in spool bottom. Due to the parallel design of the roving frame, the number of bobbins replaced by workers in the same batch is large, and when the bobbins are replaced, spline grooves at the bottom of the bobbins are aligned with the spline shaft to be accurately inserted, so that the bobbin replacement efficiency is greatly affected. Disclosure of utility model Accordingly, the utility model aims to provide a roving frame forming lifting device, which solves the problem that a spline groove at the bottom of a roving frame can be accurately inserted only by aligning with a spline shaft when the bobbin is replaced, and has a great influence on the replacement efficiency of the bobbin. Based on the above purpose, the utility model provides a roving frame forming lifting device, which comprises a base, a lifting table and a lifting part for driving the lifting table to move up and down, wherein the top of the lifting table is provided with a placing groove matched with the bottom of a bobbin.
