Split stamping and splicing type weaving shuttle of fishing net weaving machine and assembling method of split stamping and splicing type weaving shuttle

Abstract

The invention discloses a split stamping and splicing type weaving shuttle of a fishing net weaving machine. The weaving shuttle comprises a steel shuttle cover shell, a shuttle shell seat and a pressing piece, wherein the shuttle cover shell and the shuttle shell seat are fixedly connected along the periphery; a thread outlet is formed in the shuttle head of the weaving shuttle; a thread inlet is formed in the inner side face of a reel hole; one end of the pressing piece is installed on the shuttle cover shell, and the other end of the pressing piece can press a reel; and a thread guide column is arranged between the thread inlet and the thread outlet. Through the improvement of the structure and the material, on the premise that the use function of the fishing net weaving shuttle is guaranteed, a splicing structure of two steel plate stamping parts is adopted, the thread inlet, the thread outlet and the like of the weaving shuttle are naturally formed through a butt joint structure, additional machining is not needed, machining and assembling of a shuttle body are simplified, the overall strength of the shuttle body is improved, internal threading, winding and unwinding of the fishing net weaving shuttle are more convenient, the application range of the net thread diameter of the weaving shuttle is widened, and the weaving shuttle is good in abrasion resistance, light in weight, high in production efficiency, short in production period, long in service life, low in manufacturing cost and low in thread breakage rate.

Description

technical field [0001] The invention relates to the field of fishing net looms, in particular to a split stamping splicing weaving shuttle of a fishing net loom. Background technique [0002] The development of fishing net looms has a history of several decades. With the continuous development of the national economy, the manufacturing level and production technology of fishing net machines have also made a qualitative leap. Not only are they more automatic and scientific, but they are also more humanized and safer. The private fishing net factory has also gradually developed from the initial scattered small workshop production to a large-scale fishing net production base of centralized chemical factory. The manufacturers of fishing net weaving machines have also been committed to the development of new products and the improvement of technical quality. I believe that with the development of the times, the quality of fishing net machines in our country will become more and m...

Problems solved by technology

[0003] The weaving shuttles used in existing fishing net looms are all copper shuttles, which are cast from brass into copper shuttle blanks and can be obtained through multiple processing procedures. The existing production technology includes the following procedures: mold making-casting-sanding ——polishing——calibration——wire core hole in the car——drilling (photoelectric disconnection hole, pressing plate installation hole, porcelain sleeve installation hole, vertical wire retaining pin installation hole)——milling in and out wire holes——milling Tablet pressing groove—grinding the plane of the shuttle head—grinding the wire hole by the fitter—installation of the wire inlet porcelain sleeve——installation of the wire retaining pin——pressing sheet assembly, the copper weaving shuttle product with this structure has a low casting yield , the proportion of mechanical processing is high, manual grinding, calibration, assembly workload and assembly precision requirements are high, the production cycle of the product is 3 to 4 days, the production efficiency is low, and it needs to consume precious metal brass, this is regarded as the so-called high-end fishing net The weaving shuttle parts have low hardness, poor wear resistance, short service life, and low casting yield. There are three broken wire gaps in the lead wire path, and the wire breakage rate is high. The design of the solid brass casting type weaving shuttle structure is not good. Reasonably, the hole diameter of the outlet hole of the weaving shuttle is limited, because the thickness of the weaving shuttle is fixed, a through hole must be drilled on a specific thickness, and a wear-resistant porcelain sleeve is installed in the through hole, the maximum aperture of the porcelain sleeve is limited. Due to the different wire diameters of fishing nets of different specifications, corresponding fishing net looms must be used for fishing nets of different specifications. There are many specifications of existing fishing net looms, and there are more specifications of weaving shuttles. The diameter range of the weaving mesh wire that the machine is suitable for is very small. At the same time, the manufacturing quality of the existing overall copper weaving shuttle product will be affected by the fluctuation of artificial factors, and the product quality is difficult to control.
