Fourth roller speed automatic regulating device

Abstract

The present invention discloses an automatic fourth-roller speed regulating device, mainly comprising a front roller signal follower, a fourth-roller driver and an automatic fourth-roller speed regulator, wherein, the front roller signal follower converts the rotation signals of a front roller into angle analog signals; the automatic fourth-roller speed regulator receives the angle analog signals, sends out instructions and controls the fourth-roller driver to move. A fourth roller is provided between the front roller and a jaw, increasing a new space, and a fully elongated fiber bundle can be sorted out and processed in the new space, for instance, changing the width of the fiber bundle, adding filaments in and having the speed of the fourth roller automatically track the running speed of the front roller through the automatic regulator. The present invention can be used for the agglomeration process of fiber strand and so on. The moving speed of the fourth roller is regulated according to technological requirements, contrasted with the front roller to reach different speed ratio, so as to meet various technological requirements.

Description

technical field [0001] The utility model relates to a ring spinning frame, in particular to a roller speed regulating device. Background technique [0002] In the production of the traditional ring spinning frame, the roving is unwound from the roving bobbin, and the roller device of the drafting system is composed of the rear roller 14, the middle roller 15 and the front roller 16, such as figure 2 Shown: In the main drafting zone, the fiber strands are drafted to the required yarn count, while at the same time the internal adhesion of the strands is completely lost. Each fiber is in a free state when it reaches the front nip, and these fibers are twisted together to form a final single yarn after leaving the nip. After the drafted fiber strands are drafted by the front roller 13, the fiber strands are continuously fed into the twisting area from the nip. The ring spinning frame with such a structure can only complete simple processes and cannot meet the requirements of to...

AI Technical Summary

Problems solved by technology

After the drafted fiber strands are drafted by the front roller 13, the fiber strands are continuously fed into the twisting area from the nip. The ring spinning frame with such a structure can only complete simple processes and cannot meet the requirements of today's new technologies. Process requirements, such as: the process of agglomeration of fiber strands or the process of mixing different fibers cannot be realized
