Manufacturing tool for netting machine net rolling roller and manufacturing method of net rolling roller

Abstract

The invention relates to a manufacturing tool for a netting machine net rolling roller and a manufacturing method of the net rolling roller in the field of fishing net weaving machines. One end of a spindle is in transmission connection with a drive mechanism, and a three-jaw chuck is arranged at the other end of the spindle. A second support is obliquely provided with a scraper. A third support is provided with a sliding groove, a sliding block is arranged in the sliding groove, and a guide rail plate guiding the sliding block is arranged on the outer side of the sliding groove. A threaded hole is longitudinally formed in the sliding block. The third support is rotationally provided with an adjusting lead screw engaged with the threaded hole. A carrier roller frame is relatively fixed with the sliding block, and the carrier roller frame is provided with two carrier rollers with parallel axes. When the net rolling roller is manufactured, the scraper is attached to the side face of a roller body, a gap is reserved, putty is added in the rotating process, and a layer of non-woven fabrics is bonded through resin after solidification. By means of the above device and method, a main net rolling roller, a main warp conveying roller and a rear net rolling roller can be manufactured, influences brought by welding deformation and out-of-roundness can be eliminated, and the consistence of tension of warps is guaranteed.

Description

technical field [0001] The invention relates to a processing tool and a processing method for a net weaving machine, in particular to a processing tool for a net roll of a net weaving machine and a manufacturing method for the net roll. Background technique [0002] In the prior art, a netting roll is used on a net weaving machine for weaving fishing nets. The structure of the netting roll mainly includes a roll body, flanges are welded at both ends of the roll body, and an end shaft is welded at the center of the flange. , when working, the end shaft is rotatably supported on the frame, and the end shaft can be connected with the drive mechanism to wind the fishing net on it to realize the net rolling function. The roller body is usually made of seamless steel pipe or cold-drawn welded pipe. The surface of the roller body is smooth and clean. In order to avoid slipping when winding the fishing net, the surface can be roughened or pre-wrapped with an anti-skid layer. On the ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: errors in the manufacturing process of the roller body, flanges and end shafts, and welding deformation and other factors will cause problems such as out-of-roundness of the roller body and different axes at both ends. The tension generated on the surface will be inconsistent, which will affect the quality of the product
