A kind of preparation method of fluorocarbon variable-diameter fishing line

Abstract

The invention discloses a drafting device and preparation method of a fluorocarbon variable-diameter fishing line. The drafting device comprises a machine frame and a drafting roller set arranged on the machine frame; the drafting roller set includes a heating roller and a drafting roller which are arranged in the line feeding direction side by side, and the heating roller is arranged on the line feeding side of the drafting roller; the distance for drafting forming is formed between the heating roller and the drafting roller, and pressing rollers which are matched with the heating roller and the drafting roller and used for pressing the variable-diameter fishing line are arranged on the heating roller and the drafting roller; and the machine frame is further provided with a pressure adjusting mechanism for adjusting the pressure of the pressing rollers. According to the drafting device and preparation method of the fluorocarbon variable-diameter fishing line, the heating roller and the drafting roller are arranged, the fishing line needing to be subjected to diameter varying is tightly pressed on the heating roller and the drafting roller through the pressing rollers, the distance for drafting forming is obtained, thus, corresponding variable-diameter drafting is achieved so that the effect that the thick section and the thin section of the fishing line are drafted in different time periods can be ensured, the corresponding drafting speed and time are set, the forming problem of the fluorocarbon variable-diameter fishing line is well solved, moreover, the product quality of the fluorocarbon variable-diameter fishing line is improved, and the high-precision variable-diameter requirement is met.

Description

technical field [0001] The invention relates to a fishing line production method, in particular to a drafting device for a fluorocarbon variable-diameter fishing line and a preparation method thereof. Background technique [0002] As a kind of fishing line, variable-diameter fishing line generally has a length of 2.2 meters, 2.7 meters, 3.6 meters, 4.5 meters, etc. In actual production, in order to improve production efficiency, the fishing line is continuously stretched into a thick section-variable section -Slim section-reduced diameter section-thick section connected in sequence, straight lines with different wire diameters, cut from the midpoint of the thick section and the midpoint of the thin section after wire drawing to form a "thick section-reduced diameter Section-fine section" finished product. The thin thread of this reduced-diameter thread is tied to the hook, and the thick thread is fastened to the connecting tool. This kind of line is characterized by strong...

Problems solved by technology

[0004] Compared with PA nylon raw materials, PVDF has the characteristics of high hardness, high toughness, fast heat conduction, and large shrinkage deformation. If nylon variable-diameter fishing line equipment is used, the production is more difficult and the drafting efficiency is low due to the different material properties of the two materials. , poor drafting effect

[0005] In addition, the existing variable-diameter fishing line is formed through the secondary drafting of the water-bath drafting tank behind the extruder and the conventionally arranged drafting roller group. The drawing speed is realized, and the secondary drafting is completed by the conventionally arranged drafting roller group using the same drafting speed, that is, the same drafting speed is used for the thick section, the variable diameter section and the thin section of the fishing line. This drafting method is likely to cause the thick section to be unable to be pulled apart or the pulling effect is not ideal, and the thin section will be broken, which is especially not suitable for the drafting of fluorocarbon variable-diameter fishing lines. At the same time, the drafting part of the existing drafting machine and The heating part is set separately, heating first and then drawing, in the case of low ambient temperature, it will seriously affect the drawing effect
