Circular heald frame

Abstract

The invention provides a circular heald frame. The circular heald frame comprises heald rings passing through warp yarns, wherein the heald rings are respectively rotationally connected to two surfaces of one driving disc, and the heald rings distributed on two surfaces are in symmetrical arrangement with respect to the center of the driving discs; the edges of the driving discs are provided with guide rails or grooves; one sides of the driving discs are arranged in a driving holder in a sliding mode; the driving holder is internally provided with a guide rail in sliding fit with the guide rails or the grooves and a driving mechanism driving the driving disc; the driving discs are arranged in an array mode along the axis so as to form the heald frame to enable warp yarns to be layered up and down. The rotation of the driving discs enables the heald rings which are rotationally connected to the disc surfaces to move vertically alternatively, and further the warp yarns complete the spinning motion in vertical alternative motion; because the heald rings are symmetrically distributed on the driving discs, the rotation of the heald rings and the driving discs always keeps centrifugal motion without losing kinetic energy, thereby achieving the aim of saving energy consumption.

Description

Technical field [0001] The invention relates to the field of loom equipment, in particular to a circulating heald frame for a loom. Background technique [0002] The heald frame is an important part of the loom, which is a frame with heald rods and driving parts connected by upper and lower beams and left and right side rails. After the piece heddle is arranged on the heald frame, the warp thread that penetrates into the piece heddle is integrated into one body, and with the movement of the heald lifting mechanism of the loom, the heald frame moves up and down according to the program of the shedding device, so that the warp yarn is layered and opened, and the weft yarn is placed in the warp yarn. Shuttle, and interweave into fabrics of different patterns. The heald is the main part of the heald frame, and the heald is made of wire, steel wire or steel sheet. There is a small hole (heald eye) in the middle for the warp thread to pass through. When each heddle controls a w...

Problems solved by technology

[0003] More than two heald frames move up and down repeatedly to make the warp yarns form a shed for continuous weaving. This repeated up and down movement causes repeated loss of kinetic energy applied to the heald frames, resulting in huge energy consumption of the motor driving the heald frames. At the same time, because the current weaving machinery generally pursues high speed, it can only be achieved by continuously increasing the speed of the heald frame’s repeated movement. Constrained by the bottleneck of heald frame movement
