Description

Technical Field

[0001] This utility model relates to the field of electromagnetic induction heating roller technology, specifically a high-temperature electromagnetic induction heating roller heating coil that is easy to replace. Background Technology

[0002] With the continuous advancement of industrial technology and the increasing awareness of environmental protection, traditional heating methods such as heat transfer oil heating rollers and electric heating rollers are no longer sufficient to meet the needs of modern industrial production due to their high energy consumption, inconvenient maintenance, and susceptibility to pollution. Electromagnetic induction heating technology, as a highly efficient, energy-saving, and environmentally friendly heating method, has gradually been widely used in industrial production.

[0003] Electromagnetic induction heating rollers are heating devices designed based on the principle of electromagnetic induction. They utilize alternating current passing through a coil to generate an alternating magnetic field, which induces eddy currents in the metal object being heated. As these eddy currents flow within the metal object, they generate heat due to resistance, thus achieving the heating purpose. This heating method has advantages such as high temperature, good temperature uniformity, low energy consumption, and no pollution.

[0004] However, the following problems still exist: The heating coil is one of the core components of the heating roller, and its performance directly affects the heating effect and lifespan of the heating roller. The existing heating roller is a complete cylinder. When the heating coil inside the roller is damaged or its performance deteriorates, it is not convenient to open the roller or remove it to repair or replace the heating coil. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a high-temperature electromagnetic induction heating roller heating coil that is easy to replace, allowing for quick replacement of the heating coil.

[0006] This utility model provides the following technical solution: a high-temperature electromagnetic induction heating roller heating coil that is easy to replace, characterized in that: it includes a placement tube, on the surface of which are formed an arc-shaped groove one and an arc-shaped groove two. A heating coil one is installed in the arc-shaped groove one, and a heating coil two is installed in the arc-shaped groove two. Support tube one and support tube two are detachably connected to the two ends of the placement tube, respectively. A bearing one is fixedly connected to support tube one, and a bearing two is fixedly connected to support tube two. A fixing seat is fixedly connected to both bearing one and bearing two. The two fixing seats face opposite directions. Two semi-cylindrical shells are detachably connected to the two fixing seats. A gear is fixedly connected to bearing one.

[0007] Furthermore, the first bearing is the same as the second bearing, both including an inner tube, balls and an outer tube. The inner tube of the first bearing is fixedly connected to the first support tube, and the inner tube of the second bearing is fixedly connected to the second support tube.

[0008] Furthermore, the sector area of ​​the cross-section of the first arc-shaped groove is smaller than the sector area of ​​the cross-section of the second arc-shaped groove, and the arrangement density of the first heating coil is greater than the arrangement density of the second heating coil.

[0009] Furthermore, the fixed base includes a connecting pipe that is fixedly connected to an outer tube of the bearing, and a flange is fixedly connected to the front end of the connecting pipe.

[0010] Furthermore, the semi-cylindrical outer shell includes an arc-shaped plate with a semi-circular cross-section, and limit plates are fixedly connected to both ends of the arc-shaped plate. The two limit plates are provided with circular holes corresponding to the flange.

[0011] Furthermore, each of the two limiting plates has two slots, and a locking block that matches the slot is fixedly connected to the flange.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This easy-to-replace high-temperature electromagnetic induction heating roller heating coil has a two-part outer shell.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 5 A replaceable high-temperature electromagnetic induction heating roller heating coil includes a placement tube 1. An arc-shaped groove 2 and an arc-shaped groove 3 are formed on the surface of the placement tube 1. A heating coil 4 is installed in the arc-shaped groove 2, and a heating coil 5 is installed in the arc-shaped groove 3. Supporting tubes 6 and 7 are detachably connected to both ends of the placement tube 1. A bearing 8 is fixedly connected to the supporting tube 6, and a bearing 9 is fixedly connected to the supporting tube 7. A fixing seat 10 is fixedly connected to both bearings 8 and 9, with the two fixing seats 10 facing opposite directions. Two semi-cylindrical shells 11 are detachably connected to the two fixing seats 10. A gear 12 is fixedly connected to the bearing 8.

[0022] like Figures 1 to 5 As shown, the easily replaceable high-temperature electromagnetic induction heating roller heating coil of this utility model, in use, is fixed by fixing the support tubes 6 and 7 at both ends of the placement tube 1, so that the heating coils 4 and 5 are in a stationary state. By driving the gear 12 to rotate through other equipment, the outer tubes of the bearings 8 and 9 can be rotated, thereby rotating the fixed base 10, which in turn drives the two semi-cylindrical shells 11 to rotate. The rotation of the two semi-cylindrical shells 11 heats the two semi-cylindrical shells 11. Since the arrangement density of the heating coils 4 is greater than that of the heating coils 5, Therefore, the heating temperature of the semi-cylindrical outer shell 11 is higher at heating coil 4, while heating coil 5 is used to keep the semi-cylindrical outer shell 11 warm, so that the temperature of the non-working surface and the working surface will not have a large difference. This allows the non-working surface to heat up quickly when it reaches heating coil 4, thus saving energy. When heating coil 4 and heating coil 5 need to be replaced, the hex bolts are removed first, which will remove the fixing effect on the two semi-cylindrical outer shells 11, thereby exposing the heating coils 4 and 5 inside the two semi-cylindrical outer shells 11 for easy replacement.

[0023] like Figure 2 or Figure 3 As shown, the bearing 8 and bearing 9 are the same, both including an inner tube, balls and an outer tube. The inner tube of bearing 8 is fixedly connected to the support tube 6, and the inner tube of bearing 9 is fixedly connected to the support tube 7.

[0024] Specifically, when the support tube 6 and support tube 7 at both ends of the placement tube 1 are fixed, the inner tubes of bearing 8 and bearing 9 are also fixed, so that the fixing seat 10 and the two semi-cylindrical shells 11 can only rotate with the outer tubes of bearing 8 and bearing 9, thereby heating the two semi-cylindrical shells 11.

[0025] like Figure 3 As shown, the sector area of ​​the cross-section of the arc-shaped groove 2 is smaller than the sector area of ​​the cross-section of the arc-shaped groove 3, and the arrangement density of the heating coil 4 is greater than the arrangement density of the heating coil 5.

[0026] Specifically, the sector-shaped surfaces of the cross-sections of the arc-shaped groove 12 and the arc-shaped groove 23 correspond to the working area and the non-working area, respectively. The arrangement density of the heating coil 14 is greater than that of the heating coil 25 in order to enable rapid heating of the semi-cylindrical shell 11 in the working area. After heat conversion, the temperature of the semi-cylindrical shell 11 located in the non-working area will decrease. The heating coil 25 can keep the semi-cylindrical shell 11 warm and preheat it here, so that the semi-cylindrical shell 11 can be rapidly heated to the working temperature after it rotates to the working area. This avoids the environment where the entire process is heated like the working area, which has low heat utilization and consumes more energy.

[0027] like Figure 4 As shown, the fixed base 10 includes a connecting pipe 1001 that is fixedly connected to the outer tube of the bearing 8, and a flange 1002 is fixedly connected to the front end of the connecting pipe 1001.

[0028] Specifically, the distance between the two fixed seats 10 is fixed, which in turn makes the distance between the two flanges 1002 fixed, thus facilitating the fixing of the two semi-cylindrical shells 11 onto the flanges 1002.

[0029] like Figure 5 As shown, the semi-cylindrical outer shell 11 includes an arc plate 1101 with a semi-circular cross-section. Limiting plates 1102 are fixedly connected to both ends of the arc plate 1101. The two limiting plates 1102 are provided with circular holes 1103 corresponding to the flange 1002.

[0030] Specifically, the inner surfaces of the two limiting plates 1102 are placed on the outer surfaces of the two flanges 1002, and the round hole 1103 is aligned with the threaded hole on the flange 1002. Hex bolts can then be used for fixing, so that the two semi-cylindrical shells 11 form a complete cylindrical shell, which wraps the heating coil 4 and heating coil 5 on the placement tube 1, and the heated object is transferred when the complete cylindrical shell rotates.

[0031] like Figure 4As shown in Figure 5, each of the two limiting plates 1102 has two slots 13, and a locking block 14 matching the slots 13 is fixedly connected to the flange 1002.

[0032] Specifically, when installing the two semi-cylindrical shells 11, the cooperation between the locking block 14 and the locking groove 13 can quickly position the round hole 1103 on the limiting plate 1102 and the threaded hole on the flange 1002, thereby saving the installation time of the two semi-cylindrical shells 11.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
