Description

Technical Field

[0001] This utility model relates to the field of heating roller technology, specifically a heat dissipation structure for an electromagnetic induction heating roller. Background Technology

[0002] Heated rollers are widely used in preheating, drying, setting, laminating, embossing, and composite processes in industries such as papermaking, printing, photocopying, textiles, rubber, plastics, and chemical fibers. They are primarily used for heating and heat processing products. The heated roller heats itself through a specific method, and its rotation heats the product running on it. Currently, the most commonly used types are thermal oil-heated rollers and electric-heated rollers. Thermal oil-heated rollers have a relatively simple structure and low cost; electric-heated rollers mostly use heating rods as a heat source, and theoretically, the roller surface can be heated to very high temperatures, meeting high-temperature requirements.

[0003] The patent with publication number CN210807704U discloses an electromagnetic induction heating roller with an internal coil, including a hollow metal shaft core. A support plate is fixedly connected to the inner surface of the hollow metal shaft core. A wire guide tube is installed inside the hollow metal shaft core. Heat insulation cotton is installed on the outer surface of the hollow metal shaft core. A microcrystalline plate is installed on the outer surface of the heat insulation cotton. A mica high-temperature wire is installed on the outside of the microcrystalline plate. This technology involves injecting superconducting liquid through an injection hole at the end of the roller surface, which then flows through a guide groove and through a through hole across the entire roller surface. This results in rapid heating, uniform temperature, and high accuracy. Temperature measuring holes are provided on the roller surface and shaft head to continuously monitor the roller surface temperature. A disassembly process hole is provided on the shaft head for convenient disassembly and maintenance. Multiple pin holes on the shaft head are used to connect the outer roller to the shaft head as a single unit, preventing displacement of the shaft head and outer roller during rotation. A sliding electric ring is provided at the roller end, and a wire drawn from inside the roller rotates with the roller during rotation, preventing signal loss.

[0004] However, the above technology still has the following problems:

[0005] Electromagnetic induction heating rollers may generate high temperatures during use. Without a good heat dissipation mechanism, this may lead to safety accidents. In some work situations, it is also necessary to quickly dissipate the temperature generated on the heating rollers into the working environment. Furthermore, in some application scenarios, the heating rollers need to be cooled down rapidly after completing their work in order to proceed with the next round of work or storage. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a heat dissipation structure for electromagnetic induction heating rollers, which allows for adjustment of the speed and effectiveness of heat dissipation.

[0007] This utility model provides the following technical solution: a heat dissipation structure for an electromagnetic induction heating roller, comprising an electromagnetic induction heating roller body, two mounting brackets connected to the outer side of the electromagnetic induction heating roller body, a housing connected to both mounting brackets, several air outlet pipes fixedly connected to the front side of the housing, a drive mechanism installed on the housing, a heat dissipation mechanism adapted to the drive mechanism installed inside the air outlet pipes, a U-shaped plate fixedly connected to the rear side of the housing, slide rails fixedly connected to both the upper and lower ends of the U-shaped plate, the upper ends of the U-shaped plate sealed by sealing plates, two fixing components for fixing the sealing plates fixedly connected to the surface of the U-shaped plate, an air inlet pipe fixedly connected to the side of the U-shaped plate, a filter screen one fixedly connected to the inner wall of the U-shaped plate, and a filter screen two provided between the housing and the U-shaped plate.

[0008] Furthermore, the driving mechanism includes a driver fixedly connected to the housing, and a rotating shaft is fixedly connected to the output end of the driver. A bevel gear arranged at equal intervals is fixedly connected to the rotating shaft.

[0009] Furthermore, the driver is a variable frequency speed control motor or a continuously variable speed motor.

[0010] Furthermore, the heat dissipation mechanism includes a second rotating shaft rotatably connected to the housing, a second bevel gear adapted to the first bevel gear fixedly connected to the end of the second rotating shaft, and a fan blade fixedly connected to the front end of the second rotating shaft.

[0011] Furthermore, the fixing component includes a tightening bolt rotatably connected to the U-shaped plate, and a limit plate rotatably connected to the tightening bolt.

[0012] Furthermore, the surface of the limiting plate is fixedly connected with an anti-slip and wear-resistant pad.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of electromagnetic induction heating roller uses a heat dissipation structure that can blow air onto the surface of the electromagnetic induction heating roller, so that the temperature generated by the electromagnetic induction heating roller can be quickly transferred to the working environment. At the same time, when the electromagnetic induction heating roller needs to be cooled after completing its work for the next round of work, cold air can be blown onto the surface of the electromagnetic induction heating roller to quickly reduce the temperature of the electromagnetic induction heating roller.

[0021] 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.

[0022] Please see Figures 1 to 5 A heat dissipation structure for an electromagnetic induction heating roller includes an electromagnetic induction heating roller body 1. Two mounting brackets 2 are connected to the outer side of the electromagnetic induction heating roller body 1. A housing 3 is connected to both mounting brackets 2. Several air outlet pipes 4 are fixedly connected to the front side of the housing 3. A drive mechanism is installed on the housing 3. A heat dissipation mechanism adapted to the drive mechanism is installed inside the air outlet pipes 4. A U-shaped plate 5 is fixedly connected to the rear side of the housing 3. Slide rails 6 are fixedly connected to both the upper and lower ends of the U-shaped plate 5. The upper ends of the U-shaped plate 5 are sealed by sealing plates 7. Two fixing components for fixing the sealing plates 7 are fixedly connected to the surface of the U-shaped plate 5. An air inlet pipe 8 is fixedly connected to the side of the U-shaped plate 5. A filter screen 9 is fixedly connected to the inner wall of the U-shaped plate 5. A filter screen 10 is provided between the housing 3 and the U-shaped plate 5.

[0023] The heat dissipation structure of the electromagnetic induction heating roller in this utility model is similar to that of existing coil-integrated electromagnetic induction heating rollers, such as the electromagnetic induction heating roller with coil integrated structure disclosed in patent CN210807704U. The main improvement of this utility model is that it can blow air onto the surface of the electromagnetic induction heating roller, so that the heat generated by the electromagnetic induction heating roller can be quickly transferred to the working environment. At the same time, when the electromagnetic induction heating roller needs to be cooled after completing its work for the next round of work, cold air can be blown onto the surface of the electromagnetic induction heating roller to quickly reduce the temperature of the electromagnetic induction heating roller. Figures 1 to 5As shown, the heat dissipation structure for the electromagnetic induction heating roller in this utility model, during use, drives the driver 11, which causes the rotating shaft 12 to rotate, thereby causing the bevel gears 13 arranged at equal intervals on the rotating shaft 12 to rotate. Since the bevel gears 13 and 15 are meshed, the bevel gears 15 rotate together with the bevel gears 13, thereby causing the rotating shaft 14 to rotate, which in turn drives the fan blades 16 to rotate, thus blowing air onto the surface of the electromagnetic induction heating roller body 1 to cool the electromagnetic induction heating roller body 1 or to blow the hot air on the surface of the electromagnetic induction heating roller body 1 into the working environment. When the electromagnetic induction heating roller body 1 needs to be cooled after completing its work for the next round of work, a cooling device (existing technology, which will not be described in detail here) and an air inlet pipe can be connected. Connect 8 to blow the cold air generated by the refrigeration equipment into the air inlet pipe 8. When the cold air enters the U-shaped plate 5, the desiccant inside the U-shaped plate 5 will absorb the moisture in the cold air, thereby conveying the cold air through the filter screen 10 into the interior of the housing 3. This allows the fan blades 16 to blow the cold air onto the surface of the electromagnetic induction heating roller body 1, quickly cooling the electromagnetic induction heating roller body 1. When the desiccant needs to be replaced, first turn and tighten the bolt 17 to stop the pressure and fixation of the limiting plate 18. Then, turn the limiting plate 18 to release the restriction on the sealing plate 7 and remove the two sealing plates 7. The desiccant will fall directly. Similarly, after installing and fixing the lower sealing plate 7, the new desiccant can be replaced. Then, the upper sealing plate 7 can be covered and fixed to continue the heat dissipation work.

[0024] like Figure 4 As shown, the driving mechanism includes a driver 11 fixedly connected to the housing 3, a rotating shaft 12 fixedly connected to the output end of the driver 11, and bevel gears 13 arranged at equal intervals fixedly connected to the rotating shaft 12.

[0025] Specifically, the driver 11 drives the shaft 12 to rotate, thereby causing the bevel gears 13 arranged at equal intervals on the shaft 12 to rotate.

[0026] like Figure 4 As shown, the driver 11 is a variable frequency speed control motor or a continuously variable speed motor.

[0027] Specifically, a variable frequency speed control motor or a continuously variable speed motor can change the rotation speed of the shaft 12, thereby indirectly adjusting the rotation speed of the fan blades 16, and thus controlling the degree of heat dissipation.

[0028] like Figure 4As shown, the heat dissipation mechanism includes a second rotating shaft 14 rotatably connected to the housing 3, a second bevel gear 15 adapted to the first bevel gear 13 is fixedly connected to the end of the second rotating shaft 14, and a fan blade 16 is fixedly connected to the front end of the second rotating shaft 14.

[0029] Specifically, since bevel gear 13 and bevel gear 15 are meshed together, bevel gear 15 rotates together with bevel gear 13, thereby causing shaft 14 to rotate, which in turn drives the fan blade 16 to rotate, thereby blowing air onto the surface of the electromagnetic induction heating roller body 1 to cool down the electromagnetic induction heating roller body 1 or to blow the hot air on the surface of the electromagnetic induction heating roller body 1 into the working environment.

[0030] like Figure 5 As shown, the fixing component includes a tightening bolt 17 rotatably connected to the U-shaped plate 5, and a limiting plate 18 rotatably connected to the tightening bolt 17.

[0031] Specifically, when the desiccant needs to be replaced, first turn and tighten the bolt 17 to stop the limiting plate 18 from being squeezed and fixed. At this time, the limiting plate 18 can be turned to release the restriction on the sealing plate 7. Remove the two sealing plates 7, and the desiccant will fall directly. Similarly, after installing and fixing the lower sealing plate 7, the new desiccant can be replaced. Then, the upper sealing plate 7 can be covered and fixed to continue the heat dissipation work.

[0032] like Figure 5 As shown, the surface of the limiting plate 18 is fixedly connected with an anti-slip and wear-resistant pad 19.

[0033] Specifically, the anti-slip and wear-resistant pad 19 can increase the friction between the limiting plate 18 and the U-shaped plate 5, thereby enhancing the fixing effect.

[0034] 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.
