Problems solved by technology

[0002] Using the eccentric wheel to control the warp opening in the weaving process is the core component of the existing heald lifting control mechanism. Due to the eccentric wheel, the opening is unstable and the shed opening changes constantly, which is not conducive to weft insertion, easy to pinch the shuttle, and stop the machine, making the weaving process difficult to control

Abstract

The invention provides a heald lifting control mechanism of a loom, relating to the technical filed of a loom, in particular to the heald lifting mechanism for controlling the opening of wraps. The heald lifting mechanism comprises a stander, a connecting rod, a connecting system and a heald frame connected with the connecting rod through the connecting system, and is characterized in that the connecting rod consists of a straight shank and a coupler body, the coupler body is connected to one end of the straight shank, the connecting rod is transversely arranged, and the straight shank end is connected with the connecting system; the middle of the couple body is fixedly connected with a rotating shaft which is supported on the stander through a bearing, two ends of the coupler body are respectively connected with a bearing; and the two bearings are both circumscribed with a conjugate cam, and the conjugate cam is connected with a crankshaft. In the invention, the control main body is the conjugate cam, therefore, the connecting rod can rapidly lift and fall in set time, the stability of the opening is good, and the variation of a shed is small, so that the control mechanism is in favor of wefting insertion and facilitating weaving.

Description

technical field [0001] The invention relates to the technical field of looms, in particular to a hedging mechanism for controlling warp opening. Background technique [0002] Using an eccentric wheel to control the warp yarn opening in the weaving process is the core component of the existing heald lifting control mechanism. The eccentric wheel causes the shedding to be unstable and the shed opening changes constantly, which is not conducive to weft insertion, easy to pinch the shuttle, and stop the machine, making the weaving process difficult to control. Contents of the invention [0003] The purpose of the present invention is to design a heald raising control mechanism of a loom with stable opening and small shed opening. [0004] The invention includes a frame, a connecting rod, a connecting system, and a heald frame. The heald frame is connected to the connecting rod through the connecting system. It is characterized in that the connecting rod is composed of a straig...
