Abstract
Description
Technical Field
[0001] This utility model relates to the field of texturing machine heating box technology, and more specifically, to a partitioned gradient heating and heat insulation structure for a texturing machine heating box. Background Technology
[0002] The heating device of the texturing machine is the core component used to heat-treat chemical fiber filaments. Its main function is to bring the fibers to a plastic state through heating, which facilitates subsequent processing such as false twisting and shaping, thereby giving the fibers elasticity.
[0003] Traditional texturing machine heating chambers include components such as heating chamber, heating plate, and heating rail. The wire passes through the heating rail and is heated. During the heating process, fumes are generated. Therefore, modern devices are also equipped with a fume extraction and purification system.
[0004] Current heating boxes utilize rail contact heating, and the heating rail is generally semi-open, which not only increases energy consumption, but also results in poor heating uniformity of the wires, poor heating effect of the wires, and uniform temperature throughout the heating rail, making it impossible to achieve gradient heating. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a partitioned gradient heating and heat insulation structure for the hot box of a texturing machine, so as to solve the problems in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution;
[0007] A partitioned gradient heating and insulation structure for a texturing machine heating box includes an insulation box. The insulation box has equidistantly arranged straight channels inside. Multiple sets of spiral coils are arranged inside the straight channels. The spiral coils are arranged in a straight line along the inner wall of the straight channels, and the coil density of the spiral coils gradually increases along the wire inlet direction. Guide members are fixedly connected to both ends of the insulation box and correspondingly cooperate with the ends of the straight channels. A metal tube is provided inside the straight channels, and the two ends of the metal tube pass through the two guide members respectively.
[0008] As a further description of the above technical solution: the guide includes an L-shaped support arm and a collar. One end of the L-shaped support arm is fixedly installed to the end of the heat insulation box by bolts, and the other end of the L-shaped support arm is fixedly connected to the outside of the collar. The collar is concentrically corresponding to the straight channel, and the end of the metal tube slides through the inside of the collar.
[0009] As a further description of the above technical solution: a locking bolt is threaded onto the collar, and the end of the locking bolt presses against the outer side of the metal tube.
[0010] As a further description of the above technical solution: the metal tube is provided with three heat insulation rings, which isolate the metal tube into segments, and each segment corresponds to a spiral coil of different density.
[0011] As a further description of the above technical solution: the inner diameter of the heat insulation ring is smaller than the inner diameter of the metal tube.
[0012] As a further description of the above technical solution: the interior of the heat insulation box is provided with a heat conduction channel that communicates with the interior of the straight channel, and each end of the metal tube is provided with an exhaust hole, and the heat conduction channel is connected to an external air purification device.
[0013] Compared with existing technologies, the advantages of this utility model are:
[0014] (1) This scheme sets up multiple sets of spiral coils with gradually increasing coil density along the direction of the incoming line in the straight channel. The electromagnetic induction generated by the spiral coils after they are energized heats the metal tube located inside the straight channel, thereby achieving non-contact heating of the wire inside the metal tube. This effectively reduces the heat loss of the traditional semi-open structure of the hot rail, thus achieving the advantages of reduced energy consumption and more uniform heating.
[0015] (2) This scheme isolates the metal tube along the axial direction into a segmented structure. Each segment corresponds to a spiral coil area with different densities in the straight channel. This design can effectively prevent heat transfer between adjacent heating areas, further enhance the independence and stability of the temperature of each zone, and ensure the accurate realization of gradient heating.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] To address the issues of current heating boxes that utilize rail contact heating, where the rails are typically semi-open, leading to increased energy consumption and poor heating uniformity and effect for the wires, Example 1 is proposed:
[0024] Please see Figures 1-4 In this embodiment, a partitioned gradient heating and insulation structure for a texturing machine heating box includes an insulation box 1. The insulation box 1 has equidistantly arranged straight channels 2 inside. Multiple sets of spiral coils 3 are arranged inside the straight channels 2. The spiral coils 3 are arranged in a straight line along the inner wall of the straight channels 2, and the coil density of the spiral coils 3 gradually increases along the wire inlet direction. Guide members 4 are fixedly connected to both ends of the insulation box 1 and correspondingly cooperate with both ends of the straight channels 2. A metal tube 5 is provided inside the straight channels 2. The two ends of the metal tube 5 pass through two guide members 4. The guide member 4 includes an L-shaped support arm 41 and a collar 42. One end of the L-shaped support arm 41 is fixedly installed to the end of the insulation box 1 by bolts. The other end of the L-shaped support arm 41 is fixedly connected to the outside of the collar 42. The collar 42 is concentrically corresponding to the straight channels 2. The end of the metal tube 5 slides through the inside of the collar 42. A locking bolt 421 is threaded on the collar 42. The end of the locking bolt 421 presses against the outside of the metal tube 5.
[0025] In this embodiment, a straight channel 2 is opened inside the heat insulation box 1, and multiple sets of spiral coils 3 with gradually increasing coil density along the wire inlet direction are set in the straight channel 2. The electromagnetic induction generated by the spiral coils 3 after being energized heats the metal tube 5 located inside the straight channel 2, realizing non-contact heating of the wire inside the metal tube 5. This effectively reduces heat loss from the traditional semi-open structure of the heat rail and reduces energy consumption. At the same time, since the density of the spiral coils 3 increases along the wire inlet direction, the metal tube 5 forms a gradient heating area with gradually increasing temperature from the wire inlet end to the wire outlet end, which meets the differentiated temperature requirements of the wire at different processing stages, improves the heating effect and wire quality. In addition, the guide members 4 at both ends of the heat insulation box 1 are fixed with collars 42 by L-shaped support arms 41. The two ends of the metal tube 5 slide through the collars 42, which not only provides stable support and guidance for the metal tube 5, ensuring its accurate relative position with the spiral coils 3, but also facilitates the installation and replacement of the metal tube 5. The locking bolts 421 on the collars 42 can be tightened after the position of the metal tube 5 is adjusted to the correct position to prevent displacement during operation.
[0026] Furthermore, to address the issue that the temperature of the entire heating track is uniform, making gradient heating impossible, a second embodiment is proposed:
[0027] Please see Figure 3 and Figure 4The metal tube 5 is provided with three heat insulation rings 51, which divide the metal tube 5 into segments. Each segment corresponds to a spiral coil 3 of different density. The inner diameter of the heat insulation ring 51 is smaller than the inner diameter of the metal tube 5.
[0028] The heat insulation box 1 has a heat conduction channel 6 that communicates with the interior of the straight channel 2. Each end of the metal pipe 5 is provided with an exhaust hole 7. The heat conduction channel 6 is connected to an external air purification device.
[0029] In this embodiment, the metal tube 5 is axially divided into segmented structures by three heat insulation rings 51 on the metal tube 5. Each segment corresponds to a region of spiral coil 3 with different densities within the straight channel 2. This design effectively prevents heat transfer between adjacent heating areas, further enhancing the independence and stability of the temperature of each zone and ensuring the precise realization of gradient heating. At the same time, the inner diameter of the heat insulation rings 51 is smaller than the inner diameter of the metal tube 5, resulting in better heat insulation between the segments of the metal tube 5. In addition, the heat conduction channel 6 inside the heat insulation box 1 is connected to the inside of the straight channel 2, and each end of the metal tube 5 has an exhaust hole 7. When the wire is heated inside the metal tube 5 and generates fumes, these fumes can enter the straight channel 2 through the exhaust hole 7 and then be promptly drawn to the external air purification equipment for treatment through the heat conduction channel 6, effectively improving the working environment and meeting environmental protection requirements. At the same time, the heat conduction channel 6 can also remove some of the heat in the straight channel 2 during the process of drawing out the fumes, which helps to maintain the stability of the working environment temperature of the spiral coil 3.
[0030] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
