Embodiment 1

[0046] This embodiment discloses a phase control system, such as figure 1 mentioned, including:

[0047] An angle acquisition module 101, configured to acquire the rotation angle information of the first terminal and the rotation angle information of the second terminal;

[0048] A phase difference calculation module 102, configured to calculate a phase difference between the first terminal and the second terminal and obtain a running speed value of the second terminal according to the phase difference.

[0049] In order to solve the problem that the yarn stop rod is controlled by the electronic weft feeder to stop the yarn from flying, so that the yarn tension suddenly increases, the yarn is stretched, and the fabric surface is flawed, in order to solve the problem of yarn weft insertion tension , this embodiment proposes a phase control system to solve the scheme of synchronous control of the main shaft of the weft feeder, detect the angle of the main shaft of the loom, and...

Abstract

The invention discloses a phase control system and method, wherein the system includes: an angle acquisition module, used to acquire the rotation angle information of the first terminal and the rotation angle information of the second terminal; a phase difference calculation module, used to calculate the The phase difference between the first terminal and the second terminal is used to obtain the running speed value of the second terminal according to the phase difference. The invention detects the rotation angle of the weft feeder motor and the main shaft of the loom in real time through phase control, and realizes the synchronous control of the weft feeder and the main shaft of the loom, so that the rotation angle of the weft feeder winding yarn can track the loom in real time The main shaft angle ensures the synchronization of yarn unwinding and weft insertion of the loom, keeps the yarn tension constant, and improves the quality of the cloth.

Description

technical field [0001] The invention relates to the field of loom technology, in particular to a phase control system and method Background technique [0002] With the development of science and technology, the traditional weft feeder is gradually replaced by the electronic weft feeder due to the complex mechanical mechanism and difficult maintenance in the later stage. After the weft insertion of the traditional loom is completed, the weft is inserted through the weft feeder. The traditional mechanical weft feeder, because it is mechanically transmitted to the main shaft of the loom, and the transmission ratio is fixed, can ensure that the weft feeder and the main shaft of the loom are completely connected. Synchronous, so that there is no problem of sudden change in yarn tension during weft insertion; and the electronic weft feeder controls the yarn stop bar to be lowered to prevent the yarn from flying, which will cause the yarn tension to suddenly increase, and the yarn ...
