Description

Roving frame drafting device

Technical Field

Background

The roving frame is a spinning machine for manufacturing fiber strips into roving, and mainly has the functions of drafting and twisting, and the roving is wound into a certain package so as to meet the requirements of spinning frame processing.

The drafting roller is a main part of a drafting mechanism of a spinning machine, and a roller clamping opening is formed by a pair of an upper roller and a lower roller to hold a sliver for drafting. When in use, the lower roller is driven to rotate by the transmission device, the lower roller drives the sliver to move by friction force, and the upper roller is usually driven by the friction of the lower roller, and a few of the upper rollers are driven by gears. The sliver fed into the drafting mechanism has a certain thickness, and in order to uniformly hold the fiber without damaging the fiber, the upper roller is required to be coated with an elastic material, commonly called a leather roller.

The improved roving frame drafting device comprises a base, wherein a mounting frame is fixed at the top of the base, a first traction roller is rotatably connected to the inside of one side of the mounting frame, a second traction roller is rotatably connected to the mounting frame, which is close to the upper side of the first traction roller, and a motor is mounted on the outer side of the mounting frame, which corresponds to the first traction roller.

However, this improved roving frame drafting device has the following problems in the actual use process:

when the friction force between the upper roller and the lower roller and the sliver is large, even the whole sliver in the sliver is easy to wind onto the roller under the influence of the friction force, so that broken ends or yarn defects are caused, the quality of the roving is reduced, if the whole sliver is wound onto the roller to cause the winding phenomenon, the machine is stopped for finishing, and the production efficiency is reduced.

Accordingly, the present application proposes a roving frame drafting device to solve the above-mentioned problems.
