Serrated knife for high-speed carpet textile machine and machining method thereof

Abstract

The invention discloses a serrated knife for a high-speed carpet textile machine. The serrated knife comprises a knife rest and a blade component, wherein the blade component comprises a plurality ofblade bodies; a plurality of sawteeth are arranged on one side of each blade body; the plurality of sawteeth are arranged at equal intervals; a plurality of mounting holes are formed in one side, farfrom the sawteeth, of each blade body; the plurality of blade bodies are detachably connected with the knife rest through the plurality of mounting holes; the end parts of the plurality of blade bodies are correspondingly spliced with one another; splicing lines are formed in spliced positions; the splicing lines are positioned at the roots of the sawteeth, so that the phenomena that the splicinglines have cracks at cutting edges of the splicing lines and the shearing quality of carpet fabric is reduced are avoided; meanwhile, the invention further discloses a machining method of the serratedknife. The serrated knife machined through the method is high in quality, sharp in cutting edges and long in service life, and improves the shearing efficiency of the carpet fabric.

Description

technical field [0001] The invention relates to the technical field of carpet weaving machines, in particular to a serrated knife of a high-speed carpet weaving machine and a processing method thereof. Background technique [0002] After the carpet fabric is warp-knitted and weft-knitted by the textile machine, the surface of the carpet fabric is likely to have different lengths of plush fibers. At this time, it is necessary to use a serrated knife to trim the plush evenly. [0003] Usually the serrated knives used on high-speed carpet textile machines are used for splicing two serrated knives together, but the splicing line of the sawtooth is often not at the root of the tooth, but on the cutting edge. When the carpet fabric is cut with this cutter, there are burrs in the trimmed carpet fabric, which reduces the quality of the carpet fabric and increases the production cost. Therefore, in order to improve pruning efficiency and pruning quality, the requirements for serrate...

AI Technical Summary

Problems solved by technology

[0004] At the same time, the processing accuracy of the existing serrated knives is low, so that the processing quality of the serrated knives has the following problems: ① there is an error in the tooth pitch; Good; ④The hole spacing deviation of the mounting holes on the serrated knife is large, which affects the quality of the product and reduces the production efficiency
