Description

A fishing float and a preparation method thereof TECHNICAL FIELD

[0001] The present application belongs to the technical field of fishing, and particularly relates to a fishing float and a preparation method thereof. BACKGROUND

[0002] The float is one of the indispensable tools in fishing activities, which is mainly used to indicate the condition of fish biting the hook and help the fisherman to judge whether the fish is hooked or not. The early floats were mostly made of natural materials such as feathers, wood blocks, bamboo, etc. With the development of technology, the materials and technology of modern floats have also undergone significant changes, for example, using lighter and more durable artificial materials, and introducing advanced processing technology and design concepts. Traditional float materials include various types of wood, bird feathers, etc. These materials are light but prone to deformation due to moisture. In recent years, with the progress of research on new materials, some high polymer materials and composite materials have been widely used in float manufacturing. For example, nano-composite materials are favored due to their excellent physical properties such as high strength, low density, good weather resistance, etc. In addition, the early float design is relatively simple, usually only a basic floating body structure, most of the floats are made by hand, which can ensure a certain quality, but the efficiency is low. For the float, sensitivity is one of the important indicators to measure its performance. A good float needs to quickly and accurately transmit the information of fish biting the hook to the fisherman. Due to long-term exposure to outdoor environments, the float needs to have good weather resistance and corrosion resistance. Therefore, based on the above problems, it is necessary to develop a fish float with excellent strength performance, sensitivity and durability. SUMMARY

[0003] In view of the defects of the prior art, the purpose of the present application is to provide a fishing float and a preparation method thereof.

[0004] The technical effects of the present application are realized by the following technical scheme: a fishing float, which is composed of the following raw materials: polymethacrylimide foam material, space beans, fine metal needles, hollow cylindrical polycarbonate plastic tubes, golden paint, fluorescent paint, epoxy primer, polyurethane varnish, and fishing line.

[0005] Preferably, another aspect of the present application provides a preparation method of a fishing float, and the specific preparation steps are as follows:

[0006] S1: cutting the polymethacrylimide foam material into a cuboid float blank with a size of 6.5*6.5*30mm;

[0007] S2: punching the cuboid float blank prepared in step S1, the punching position is located at the 6.5*6.5mm square, and a through hole with a diameter of 0.5mm is punched in the middle;

[0008] S3: After the step S2 operation is completed, any one end of the hole is selected, a 10mm deep cylindrical groove is punched using a drill bit with a diameter of 1.45mm;

[0009] S4: After the step S3 operation is completed, a 7mm deep cylindrical groove is punched at the other end of the cuboid float blank using a drill bit with a diameter of 0.8mm;

[0010] S5: Two space beans are strung together with a thin metal needle with a diameter of 0.35mm to obtain a space bean string;

[0011] S6: The space bean string prepared in step S5 is implanted into the 10mm deep cylindrical groove punched in step S3, and the space bean close to the slot is glued firmly using UV curing glue;

[0012] S7: After the step S6 operation is completed, a 7mm long, 0.8mm diameter hollow cylindrical polycarbonate plastic tube is inserted into the thin metal needle, coated with UV curing glue, and pressed into the 7mm deep groove punched in step S4 along the thin metal needle, and glued firmly;

[0013] S8: After the step S7 operation is completed, the cuboid float blank is polished to obtain a bullet-shaped float blank;

[0014] S9: The bullet-shaped float blank prepared in step S8 is primed with epoxy primer and naturally air-dried for 5h;

[0015] S10: After the step S9 operation is completed, the bullet-shaped float blank is finely ground, first polished with 600 grit sandpaper, and then polished with 1000 grit sandpaper;

[0016] S11: After the step S10 operation is completed, the bullet-shaped float blank is painted, first a 0.6mm wide gold paint line is painted in the middle of the float body using gold paint, and then a 10mm wide fluorescent paint is painted at the end with the space bean string, and naturally air-dried for 10h;

[0017] S12: After the step S11 operation is completed, the bullet-shaped float blank is immersed in polyurethane varnish, and then a fishing line is inserted to obtain a fishing float.

[0018] Preferably, in the space bean string in step S6, the first space bean close to the slot is glued and fixed to prevent falling, and the second space bean away from the slot is not glued to maintain elasticity.

[0019] Preferably, the impregnation operation parameters in the step S12 are repeated for 4 cycles, each cycle interval is 2h, after each coating, the bullet-shaped float embryo is inserted on the rotating disc, and naturally air-dried at a speed of 30rpm, and naturally air-dried for 48h after completing the cycle impregnation treatment; the fishing line is threaded into the through hole punched in step S2.

[0020] The beneficial effects of the present application are as follows:

[0021] The present application uses polymethylacrylimide foam material as the base material, which has better strength-to-weight ratio, durability and sensitivity than traditional wood, feather and other materials. The present application uses grooves of specific size for placing space beans, grooves of different depths and diameters achieve different functions. The float designed in the present application does not use injection molding, the space beans located at the groove opening play the main locking role, and the space beans located at the tip of the float help to maintain the vertical stability of the float, reduce the influence of water flow on the float, and enhance its stability and sensitivity in water. In addition, the space beans do not need to be filled by injection molding, and do not need special molds to fix the space beans, which can effectively reduce the production complexity and cost. The space beans are hollow cylindrical rubber materials with elastic stretch, which can clamp even when a very thin fishing line passes through; when adjustment is needed, the position can be adjusted by pulling the float with bare hands, and the elastic clamping allows the float to stay at any position of the fishing line, making it convenient and fast to use. Specific size thin metal needles, plastic tubes and space beans are used and fixed with glue to ensure that the components will not easily fall off during use. The hollow cylindrical polycarbonate plastic tube effectively prevents the fishing line from scratching the float.

[0022] The embryo is polished into a bullet shape to reduce water resistance and improve the response speed of the float; multi-layer paint treatment (primer, fluorescent paint, clear topcoat) is used in combination with a turntable to ensure the uniformity and gloss of the paint surface and to improve the appearance and durability of the product. Steel wire of a specific length and diameter is used as a connecting piece, which is fixed by an aluminum sleeve and hot melt glue, facilitating the replacement of the float and increasing the stability of the device. Precise punching and multiple groove processing (including punching a through hole in the middle of one end of the square and using different diameter drill bits to punch different depth cylindrical grooves at both ends) ensure the complexity and functionality of the internal structure of the float. Finally, the multi-layer painting process of primer, fine grinding, fluorescent paint and clear topcoat makes the float more visible in low light conditions, improving the appearance and durability, especially when using a turntable to naturally dry the clear topcoat, ensuring that the paint surface is uniform and bright, avoiding uneven paint surface. Through careful design of the volume and pore size, and through the protective layer of epoxy primer and multiple layers of polyurethane varnish, the buoyancy and stability of the float in water are enhanced, while maintaining the sensitivity to water flow and fish bites; the use of gold and fluorescent paint in the middle and end of the float improves the visibility in various water bodies and lighting conditions, which helps to attract fish and facilitates the angler to observe the state of the float; multiple coating and curing processes ensure that the float has good water resistance and weather resistance, which means that the float can be used for a long time in different environmental conditions without being easily damaged.
