Detection equipment for reed

Abstract

The invention discloses detection equipment for a reed, and the equipment comprises a clamping mechanism which comprises two pressing blocks, wherein the clamping mechanism comprises a screw rod whichpenetrates through the two pressing blocks together, a nut which is in contact with the pressing blocks is assembled on the screw rod, the reed is clamped between the two pressing blocks together, and a plurality of row teeth are arranged on the reed in a single row; a shifting mechanism which comprises a translation block arranged between the two pressing blocks, wherein a lead screw penetratesthrough the translation block, a rotating motor for driving the translation block to translate in the length direction of the lead screw is arranged on the translation block, a shifting tongue in intermittent contact with the row teeth is arranged on the translation block, the shifting tongue is made of an elastic material, microphones are symmetrically arranged on the translation block and located on the two sides of the shifting tongue respectively, and the vertical distances from the two microphones to the reed are equal; and an oscilloscope which is electrically connected with the translation block and displays the sound frequency acquired by the microphone. Whether the gaps of the row teeth on the reed are uniform or not is detected through the sound frequency of the row teeth impacted by the shifting tongue, the overall equipment cost is low, and the detection precision is high.

Description

technical field [0001] The invention relates to the field of testing equipment for textile machinery accessories, in particular to a testing equipment for steel reeds. Background technique [0002] The reed is a part of the loom. The warp thread passes between the reed teeth, and its function is to push the weft thread to the weaving fell. The structure of the reed is similar to a comb. After long-term use, there may be some deformation or looseness between the rows of teeth of the reed, and uneven widths will appear in various parts, which are difficult to detect with the naked eye. If you use visual equipment to check, the equipment cost higher. Contents of the invention [0003] The problem to be solved by the present invention is to provide a detection device for steel reed, which can detect whether the gap between the rows of teeth on the reed is uniform by using the sound frequency of the tongue hitting the row of teeth, the overall equipment cost is low, and the de...
