Guiding plate, loom heald frame, and guiding plate and loom heald frame mounting method

Abstract

The invention discloses a guiding plate, a loom heald frame, and a guiding plate and loom heald frame mounting method. The guiding plate is provided with two side plate legs, and a projecting hook structure is arranged in every side plate leg. The loom heald frame comprises the guiding plate and a heald frame crossbeam, the loom heald frame also comprises a wedge block used for fixing the guiding plate and the heald frame crossbeam, the wedge block is fixed between the top of the heald frame crossbeam and the guiding plate, a long aperture is arranged in the heald frame crossbeam, the guiding plate is provided with the two side plate legs, one projecting hook structure is arranged in every side plate leg, and the hook structures match with the long aperture of the heald frame crossbeam. The loom heald frame and the mounting method have the advantages of fast and convenient realization of the fixation of the guiding plate and the heald frame crossbeam through the wedge plate, great shortening of the assembling time, improvement of the assembling efficiency, solving of the problem of shedding of traditional guiding plates, and prolongation of the service life of the above product.

Description

technical field [0001] The invention relates to the field of loom machinery, in particular to a guide plate, a loom heald frame and an installation method between the guide plate and the loom heald frame. Background technique [0002] Most of the guide plates used in the existing heald frames are made of wood, and a small amount of guide plates of plastic materials are also included. The guide plate (hereinafter referred to as "the guide plate") is generally connected with the upper and lower beams of the heald frame by glue bonding. As far as the heald frames using wood material guide plates are concerned, in some weaving environments, such as some industrial fabrics, some liquids (such as water) are sometimes used to maintain the humidity of the warp yarns due to the needs of the weaving process. At this time, the guide plate made of wood will expand and deform due to water absorption, resulting in a change in the distance between the heald frames, affecting the stability...

AI Technical Summary

Problems solved by technology

However, the use of guide plates connected by bolts to the beams of the heald frames has also produced new problems. The specific points are as follows: firstly, it is time-consuming to assemble the guide plates, which affects the assembly efficiency of the heald frames; secondly, when the heald frames have been installed on the loom , it becomes inconvenient to replace the guide plate, especially for the operation of the lower heald frame beam

More importantly, the bolts are connected to the guide plate made of plastic, and cannot be disassembled frequently, which will easily cause the wear of the guide plate made of plastic material, and bring risks to the guide plate and the heald frame
