[0002] The spinning manifold is one of the key components in the melt spinning process. Its main function is to provide a stable thermal environment for the molten polymer melt so that the melt can flow evenly through the manifold and be cooled into filaments. During the spinning process, the heat in the spinning manifold needs to be maintained to ensure that the molten polymer melt does not cool too quickly, thereby affecting the quality of the filaments. The heating rod is usually placed inside the spinning manifold to provide the required heat.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a heating device for a spinning box, comprising a spinning box body 1 and a heating box 2;

[0022] In this embodiment, the heating box 2 is arranged on the side of the spinning box body 1, and a cavity is provided in the heating box 2, in which a hot oil part 3 is installed. The hot oil part 3 includes a heat-conducting inner tank 31 and a lower oil pipe 32, the lower oil pipe 32 is vertically installed at the bottom of the cavity, the heat-conducting inner tank 31 is installed at the top of the lower oil pipe 32, a hot oil chamber connected to the lower oil pipe 32 is provided in the heat-conducting inner tank 31, a heating wire 33 arranged around the outer periphery of the heat-conducting inner tank 31 is installed, a filter disc 34 is installed in the lower oil pipe 32, and a densely arranged filter hole is provided in the filter disc 34, and the flow cleaning part 4 rotates through the middle of the filter disc 34.

[0023] In this embodiment, a circulation cleaning member 4 is rotatably connected in the hot oil member 3. The circulation cleaning member 4 includes a rotating rod 41, a through opening is provided in the middle of the filter disc 34, the rotating rod 41 rotates through the opening and is arranged vertically, and the bottom end of the rotating rod 41 is rotatably connected to the bottom of the heating box 2, an axial flow blade 42 located in the lower oil pipe 32 is installed on the rotating rod 41, and a plurality of connecting rods 43 arranged circumferentially and located in the hot oil chamber are installed on the rotating rod 41, and a scraping sheet 44 that fits the inner wall of the heat-conducting liner 31 is installed at one end of the connecting rod 43 away from the rotating rod 41.

[0024] In this embodiment, a tubular heat-conducting member 5 is installed on the inner wall of the spinning box body 1, and the tubular heat-conducting member 5 is connected to the hot oil member 3. The tubular heat-conducting member 5 includes a heat-conducting pipe 51, which is installed on the inner wall of the spinning box body 1 and arranged in a circuitous manner, and the liquid inlet end of the heat-conducting pipe 51 is connected to the liquid inlet pipe 52, and the liquid outlet end of the heat-conducting pipe 51 is connected to the return pipe 53, and the end of the return pipe 53 away from the heat-conducting pipe 51 is connected to the top of the heat-conducting liner 31, and the return pipe 53 is connected to the hot oil chamber.

[0025] In this embodiment, a circulation member 6 is installed at the bottom of the heating box 2, which is connected with the hot oil member 3 and conducts the hot oil to the tubular heat-conducting member 5. The circulation member 6 includes a circulation pump 61 and a conducting pipe 62. The circulation pump 61 is installed at the bottom of the heating box 2. The conducting pipe 62 is transversely arranged in the heating box 2 and is located between the circulation pump 61 and the lower oil pipe 32. The two ends of the conducting pipe 62 are respectively connected with the liquid inlet end of the circulation pump 61 and the lower oil pipe 32, and the end of the liquid inlet pipe 52 away from the heat-conducting pipe 51 is connected with the liquid outlet end of the circulation pump 61.

[0026] It should be noted that: when in use, the heat-conducting inner liner 31 can be heated by the heating wire 33, and the heat generated by heating the heat-conducting inner liner 31 can be transferred to the oil inside, thereby heating the oil. Then, the oil in the heat-conducting inner liner 31 can be guided to the liquid inlet pipe 52 along the lower oil pipe 32 and the conducting pipe 62 by the circulating pump 61, so that the oil enters the heat-conducting pipe 51. The oil entering the heat-conducting pipe 51 can flow back to the heat-conducting inner liner 31 along the reflux pipe 53 to form a reciprocating cycle. When the hot oil flows in the heat-conducting pipe 51, the temperature can be transferred to the spinning box body 1, gradually heating the spinning box body 1, so that the temperature in the spinning box body 1 can be comprehensively improved, and the temperature distribution in the spinning box body 1 can be kept uniform. This structure circulates the hot oil along the heat-conducting pipe 51, so that the heat carried in the hot oil can be transferred to the entire spinning box body 1, thereby ensuring the uniformity of temperature distribution and improving the quality of product production.

[0027] When the hot oil flows through the surface of the axial flow blades 42 in the lower oil pipe 32, the axial flow blades 42 and the rotating rod 41 can be driven to rotate simultaneously, and the inner wall of the heat-conducting liner 31 can be scraped by the scraping sheet 44 connected to the connecting rod 43 to scrape off the grease attached to the inner wall of the heat-conducting liner 31. The scraped grease can be intercepted by the filter plate 34 to prevent the oil in the heat-conducting pipe 51 from flowing smoothly. This structure facilitates the cleaning of the grease on the inner wall of the heat-conducting liner 31 and can reduce the damage of the grease to the inner wall of the heat-conducting liner 31.

[0028] In a specific embodiment, a pressure relief valve connected to the hot oil chamber is installed on the heating box 2.

[0029] It should be noted that when the temperature in the heat-conducting inner liner 31 is too high, the pressure can be released through the pressure relief valve to prevent the pressure in the heat-conducting inner liner 31 from being too high, thereby ensuring that the circulation of the oil is within a safe range.

[0030] In a specific embodiment, the back of the heat-conducting inner liner 31 is connected with an oil inlet pipe communicating with the hot oil chamber. The oil inlet pipe is mainly used to guide the oil into the heat-conducting inner liner 31.

[0031] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
