Description

Technical Field

[0001] The invention relates to the technical field of hot rolling forming heating, in particular to a heating device for hot rolling forming of predetermined shaped fibers. Background Art

[0002] Fiber (Fiber) is a substance composed of continuous or discontinuous filaments. It is widely used in textiles, military, environmental protection, medicine, construction, biology and other fields. There are two categories of fibers: natural fibers and chemical fibers. Natural fibers exist naturally and are divided into plant fibers, animal fibers and mineral fibers; while chemical fibers are made through chemical treatment and processing, and can be divided into artificial fibers, synthetic fibers and inorganic fibers. The chemical composition of synthetic fibers is completely different from that of natural fibers. They are synthesized from some substances that do not contain cellulose or protein, such as petroleum, coal, natural gas, limestone or agricultural and sideline products, and then made into fibers by chemical synthesis and mechanical processing. Such as polyester fiber (polyester), polyamide fiber (nylon or nylon), polyvinyl alcohol fiber (vinylon), polyacrylonitrile fiber (acrylic fiber), polypropylene fiber (polypropylene fiber), polyvinyl chloride fiber (chlorofiber), etc. The filling of fibers can effectively improve the strength and stiffness of plastics. Fiber-reinforced plastics are rigid structural materials. Fiber-reinforced plastics mainly have two components. The matrix is ​​a thermosetting plastic or a thermoplastic plastic, which is filled with fiber materials. The strength of the fiber matrix is ​​usually low, while the fiber filler has high rigidity but is brittle. Boron fiber itself is a composite material of tungsten wire and boron, with a high elastic modulus, but the fiber is thick and the manufacturing cost is high. Epoxy resin is often used as the matrix. Low-density aramid fiber has been used in China. It is used for cables and load-bearing components that bear tensile stress. The surface treatment is to coat the fiber surface with a surface treatment agent. The surface treatment agent includes a wetting agent and a series of coupling agents and additives. The coupling agent can form a good bonding interface between the fiber and the matrix resin, thereby effectively improving the bonding strength of the two, and also improving the waterproof, insulating and wear-resistant properties of the reinforced plastic. When the fiber is finalized, it needs to be hot-rolled and heated.

[0003] The announcement number of China's authorization is CN214882329U, which is a hot rolling forming device used for non-woven fabric production. The first blower blows air through the air inlet pipe and the air outlet cover, and the electric heating pipe heats the blown air. The high-temperature air is blown onto the non-woven fabric, which can increase the temperature of the non-woven fabric and achieve the effect of preheating the non-woven fabric, avoiding the sudden increase in temperature when the non-woven fabric contacts the hot rolling roller, causing the non-woven fabric to deteriorate in elasticity, and making the non-woven fabric quality stable. The cleaning motor drives the cleaning brush to rotate, which can clean the fibers or debris on the hot rolling roller, and the moving motor drives the cleaning brush to rotate. The driving rod is driven to rotate, and then the slider is moved through the gear and rack to keep the cleaning brush away from the hot rolling roller to prevent the high temperature of the hot rolling roller from affecting the cleaning brush. The hot rolling box can be blown through the second blower and the blow pipe, and the heat on the non-woven fabric can be taken away by the cold air from the outside. There are multiple blow pipes and multiple blowing holes on the blow pipe, so that the area of ​​the non-woven fabric receiving the cold air is increased. The non-woven fabric bypasses multiple transmission rollers to lengthen the length of the non-woven fabric in the hot rolling box, ensuring that the temperature of the non-woven fabric is relatively low after leaving the hot rolling box. When it is rolled up later, the non-woven fabric will not stick together due to the high temperature.

[0004] There are still certain shortcomings when using it. The fiber heating temperature cannot be displayed and adjusted accordingly according to actual needs, thereby reducing the practicality and scope of use of the heating device when in use. In addition, the two surfaces of the fiber cannot be heated at the same time, which will also reduce the shaping heating effect of the fiber. At the same time, pungent gas will be emitted when the fiber is heated, and the gas emitted into the air will cause air pollution. Summary of the invention
