Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber production equipment, in particular to a chemical fiber heating component and a heater with the component. Background Art

[0002] The forming of chemical fibers is the process of extruding the spinning fluid from the spinneret at a certain flow rate and solidifying it into fibers.

[0003] In the prior art, chemical fiber yarns are mostly stretched using hot roller stretching, such as the chemical fiber ITY integrated spinning equipment disclosed in Chinese patent CN220788899U, which includes an extruder, a static mixer, a spinning box, a side-blowing device, a tunnel, a pre-netting device, an adjustable cold roller, a first hot roller device, a second hot and cold roller device, a lower godet, an upper godet, a main netting device, and a winding mechanism. During operation, the molten melt is extruded from the extruder into the melt main pipe and static mixer, and then flows into the common spinning box. The melt is then distributed to two metering pumps on the left and right. The first and second metering pumps accurately distribute the melt to two five-hole spinning assembly blocks. Each spinning assembly block is equipped with a set of spinning packs. The spinneret in each spinning pack is divided into two bundles of fluid precursors, totaling 20 bundles of fluid precursors. Then, all of them enter the same set of side-blown air. After side-blown cooling and oiling by the nozzle, the ten bundles of yarn on the left pass through the pre-netting device to undergo the FDY section heating roller heating and full draft spinning process; the ten bundles of yarn on the right pass through the yarn guide mechanism and upper and lower yarn guide disks to adjust the tension and perform the POY section spinning process. After the two bundles of yarn have been spun in their respective sections, the FDY and POY yarns in the two branch sections are matched in sequence, combined and entered into the main netting device for netting and knotting, and finally enter the winding mechanism to be wound into yarn cakes.

[0004] In the aforementioned prior art, chemical fiber yarns are heated and stretched by means of hot rollers. The hot rollers are large in size and need to be customized in length according to the arrangement and number of the yarn outlets of the spinning box. Not only are they expensive, but when different types of chemical fiber yarns are produced, the hot rollers need to be replaced, which is troublesome to replace and has high maintenance costs. During the process of the chemical fiber yarns being wound and heated on the hot rollers, the oil on the yarn bundles will precipitate onto the hot rollers and may even coke. In order not to affect the quality of the yarn bundles, the hot rollers need to be stopped and cleaned regularly. During cleaning, the surface of the hot rollers is mostly cleaned manually with a scraper, which is not only inconvenient to operate but also affects production efficiency. Utility Model Content

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Example 1:

[0026] A chemical fiber heating component, the improvement of which is that: it includes a heating component body 1, the heating component body 1 includes a heating tube support 11, a wire guide tube 12 and a heating tube 13, the heating tube support 11 is provided with an accommodating channel running through it from top to bottom, the wire guide tube 12 is placed in the accommodating channel, the heating tube 13 is installed inside the heating tube support 11 and is evenly arranged on the outer periphery of the wire guide tube 12, the length of the heating tube 13 matches the length of the heating tube support 11, the heating tube 13 is used to heat the chemical fiber inside and inside the wire guide tube 12, the front side of the heating tube support 11 is provided with a through groove I111 connected to the accommodating channel, and the front side of the wire guide tube 12 is provided with a through groove II matching the through groove I111.

[0027] In this embodiment, the heating component body 1 is placed vertically, and the diameter of the wire guide tube 12 matches the diameter of the accommodating channel. After the chemical fiber yarn comes out of the spinning box, it is cooled and shaped, and then enters the wire guide tube 12 through the through groove I111 and the through groove II, and then is pulled to the winding device and the chemical fiber yarn is wound on the winder. The wire guide tube 12 is continuously heated by the heating tube 13, thereby heating the chemical fiber yarn entering the wire guide tube 12. The heated and softened chemical fiber yarn is stretched under the action of gravity, and then wound and shaped by the winder to form a finished product. The heating tube support 11 is a relatively closed space, and the wire guide tube 12 and the heating tube 13 are placed in the heating tube support 11, so that the heating tube 13 has a higher heating efficiency for the wire guide tube 12. The length of the heating tube 13 matches the length of the heating tube support 11, so that the wire guide tubes 12 located in the heating tube support 11 can all be heated. The heating tubes 13 are evenly arranged on the outer periphery of the wire guide tubes 12, so that the wire guide tubes 12 are heated evenly, and then the chemical fiber inside the wire guide tubes 12 are heated evenly.

[0028] The present embodiment provides a chemical fiber heating component, which heats the chemical fiber to stretch it through the heating component body. Compared with the method of using a heating roller to heat and stretch the chemical fiber in the prior art, the structure is simpler; the heating tube 13 directly heats the wire guide tube 12 with the chemical fiber built in, reducing energy loss; and the heating component body serves as a basic unit, which can be used in combination according to the arrangement and number of the wire outlets of the spinning box, and can adapt to the production of more chemical fiber types, which is more flexible and practical; when the wire guide tube needs maintenance due to long-term use, the wire guide tube 12 can be directly replaced, which is not only low in cost but also quick and simple to maintain, with minimal impact on production efficiency.

[0029] Furthermore, the front end size of the cross section of the through groove I111 is larger than the rear end size, and the size of the through groove II matches the rear end size of the through groove I111, thereby making it easier for the chemical fiber yarn to enter the wire guide tube 12 from the front side of the heating tube support 11.

[0030] Furthermore, the number of the accommodating channels in the heating tube support 11 is two, and they are spaced apart on the left and right sides.

[0031] In this embodiment, there are two accommodating channels, that is, the number of the wire guide tubes 12 in the heating component body 1 is two, which can accommodate a larger number of chemical fiber bundles.

[0032] Furthermore, there are three heating tubes 13 , which are arranged crosswise and at intervals with the wire guide tubes 12 , that is, heating tubes 13 are provided on both sides of each wire guide tube 12 , so that the wire guide tubes 12 are well and evenly heated.

[0033] Furthermore, the heating tube 13 is in a long O-shape, that is, two heating tubes are arranged in a vertical direction, thereby making the heating efficiency higher.

[0034] Furthermore, heating tube support plates 14 are installed in the upper and lower parts of the heating tube support 11 , and the heating tubes 13 are installed on the heating tube support plates 14 .

[0035] Furthermore, the diameter of the wire guide tube 12 is equal at the top and bottom or gradually decreases from top to bottom.

[0036] In this embodiment, the diameter of the wire guide tube 12 gradually decreases from top to bottom, which can play the role of gathering the chemical fiber yarns and facilitate the subsequent winding of the chemical fiber yarn bundles.

[0037] Furthermore, the connection head 131 of the heating tube 13 is arranged at the middle of the rear side thereof.

[0038] In this embodiment, the terminal head 131 is arranged at the middle of the rear side of the heating tube 13. Compared with the terminal head 131 being arranged at the upper end or lower end of the heating tube 13, it can avoid interference with the chemical fiber thread entering or flowing out of the wire guide tube 12 and causing damage to the chemical fiber thread.

[0039] Example 2:

[0040] A heater is improved in that it comprises at least one chemical fiber heating assembly as described above.

[0041] Furthermore, the heating component body 1 is installed on the front side of the cover body 4, and a front door 2 is installed on the front side of the heating component body 1. The interior of the front door 2 is hollow and filled with thermal insulation cotton. A front sealing plate 5 is installed on the front side of the cover body 4. The front sealing plate 5 and the front door 2 are spaced apart from each other to close the front end of the cover body 4. Thermal insulation cotton is filled between the cover body 4, the front sealing plate 5 and the heating component body 1, the front end surface of the front door 2 is flush with the front sealing plate 5, the front door 2 and the front sealing plate 5 are movably connected, and the front door 2 can be opened and closed relative to the front sealing plate 5.

[0042] In this embodiment, the cover body 4, the front door 2, and the front sealing plate 5 are mutually enclosed to form a relatively closed space, and the heating component body 1 is placed in the aforementioned space. The interior of the front door 2 is filled with thermal insulation cotton, and the cover body 4 and the front sealing plate 5 and the heating component body 1 are also filled with thermal insulation cotton, that is, the heating component body 1 is surrounded by thermal insulation cotton, so that the heat preservation effect in the heating component body 1 is better, thereby reducing the heat loss of the heating tube 13, making the heating efficiency of the heating tube 13 for the wire guide tube 12 and the chemical fiber yarn higher, and reducing energy loss. The front door 2 can be opened and closed relative to the front sealing plate 5. When the chemical fiber yarn is threaded, the front door 2 is opened so that the chemical fiber yarn passes through the through groove I111 and the through groove II into the wire guide tube 12. After the threading is completed, the front door 2 is closed to play a role in heat preservation and heat insulation.

[0043] A heater provided in this embodiment heats the chemical fiber yarn to stretch it through the heating component body. Compared with the method of using a heating roller to heat and stretch the chemical fiber yarn in the prior art, the structure is simpler; the heating tube 13 directly heats the wire guide tube 12 with the chemical fiber yarn built in, reducing energy consumption loss; and the heating component body, as a basic unit, can be used in a stacked manner according to the arrangement and number of the wire outlets of the spinning box, and can adapt to the production of more chemical fiber types, which is more flexible and practical; when the wire guide tube is coked internally due to long-term use, the wire guide tube 12 can be directly replaced, which is not only low in cost but also quick and simple to maintain, minimizing the impact on production efficiency; the heating component body is filled with thermal insulation cotton, which makes the insulation effect inside the heating component body better, thereby reducing the heat loss of the heating tube, making the heating efficiency of the heating tube for the wire guide tube and chemical fiber yarn higher, and reducing energy consumption loss.

[0044] Furthermore, a plurality of transversely arranged channel steels 7 are spaced apart vertically between the cover body 4 and the heating component body 1 .

[0045] Furthermore, a plurality of transversely arranged angle steels 8 are spaced apart vertically between the cover body 4 and the heating component body 1 .

[0046] In this embodiment, the arrangement of the channel steel 7 and the angle steel 8 serves to reinforce the structure of the heating component body 1 .

[0047] Furthermore, a guide wire bracket 6 is installed at the upper and lower ends of the cover body 4, which are located at the upper and lower ends of the heating component body 1. A circular groove is provided on the guide wire bracket 6, and the circular groove matches the position and size of the guide wire tube 12 of the heating component body 1.
