Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic heating rollers, and specifically to an energy-saving roller core heating structure for an electromagnetic heating roller. Background Art

[0002] An electromagnetic heating roller is a heating roller made based on the principle of electromagnetic induction heating of metals. That is, when an induction coil passes through alternating current, an alternating magnetic field is generated around the coil. The magnetic force lines in the alternating magnetic field form a loop from one magnetic pole through the object to be heated to another magnetic pole. The magnetic force lines cut the material, generating an induced electromotive force in the object to be heated, thereby generating eddy currents. Since the object to be heated has a resistance characteristic, according to Joule-Lenz's law, the generated eddy currents cause the material to heat up. The electromagnetic heating roller plays an important role in the fields of calendering and shaping of various sheets, surface calendering of textiles and foaming materials, and thermal pressing and compounding of films and various substrates with its advantages of high efficiency, energy saving, environmental protection, and intelligence.

[0003] Currently, the patent with the publication number CN211128233U discloses a roller core for an electromagnetic heating roller with uniform heating, including a metal roller body. A cavity high-frequency alternating magnetic field chamber is provided at the center of the metal roller body. A coil skeleton is installed at the center of the high-frequency alternating magnetic field chamber, and an induction coil is wound around the coil skeleton. One end of the metal roller body is connected to an installation ring hoop through a protective ring. A composite cable group is laid at the center of the installation ring hoop, and the composite cable group is electrically connected to the induction coil. A heat-conducting fluid chamber in the shape of "艹" is arranged inside the metal roller body. Each of the two protrusions at the lower part of this "艹" shape structure abuts against a heat-dissipating rubber. Heat-conducting protrusions are arranged outside the heat-dissipating rubber. A sealing plug is installed at the end of the heat-conducting fluid chamber. By adjusting and utilizing the internal space of the high-frequency alternating magnetic field chamber, the relative contact area between the heating chamber in the middle and the heat-conducting device is increased, and the heat dissipation efficiency of the middle part of the high-frequency alternating magnetic field chamber is improved, thereby improving the uniform heating performance of the present invention and having better applicability.

[0004] However, the following problems still exist during the use of the above-mentioned roller core for the electromagnetic heating roller: The above device adopts an integrated structure, making it difficult to disassemble the roller core. However, during actual use, due to the presence of an oily heat-conducting fluid, during the use process, as the temperature of the oil fluid rises, sediments and coking will occur in the oil fluid. These substances will adhere to the inside of the equipment, affecting the normal operation and lifespan of the equipment, and at the same time, also affecting the heat-conducting effect of the device, resulting in a large amount of energy waste. Summary of the Invention

Through the above structure, the roller core inner body can be supported and limited by the support screw, and as the roller core inner body rotates, the roller core inner body starts to rotate, so that the roller core inner body can be taken out for cleaning.

[0008] Furthermore, a cleaning convex plate is fixedly installed on the upper end of the right fixed plate, and the cleaning convex plate is arranged as an arc-shaped plate structure, and the cleaning convex plate is in contact with the inner surface of the outer heat-conducting shell.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figure 1-Figure 9The present invention provides a technical solution: an energy-saving roller core heating structure for an electromagnetic heating roller, comprising a roller core inner body 1, a limiting groove 2 is provided on the outer surface of the roller core inner body, and an induction coil 3 is wound in the limiting groove 2, a metal heating plate 24 is fixedly installed on the right side of a left fixed plate 9, and the right side of the metal heating plate 24 is fixedly installed on the right fixed plate 5, a right fixed plate 5 is fixedly installed on the right side of the roller core inner body 1, and a first sealing gasket 7 is fixedly installed on the right side of the right fixed plate 5, and a first sealing plate 8 is fitted on the right side of the first sealing gasket 7, and the first sealing plate 8 is fixedly installed on the outer heat-conducting shell, a left fixed plate 9 is fixedly installed on the left side of the roller core inner body 1, and a second sealing gasket 10 is fixedly installed on the right side of the left fixed plate 9, a second sealing plate 11 is fitted on the right side of the second sealing gasket 10, and an extension plate 12 is fixedly installed on the right side of the second sealing plate 11, and the extension plate 12 is fixedly installed on the outer heat-conducting shell.

[0020] When the device needs to be used, the induction coil 3 starts to be powered, and the induction coil 3 starts to generate a magnetic field, that is, an alternating magnetic field is generated around the induction coil 3. The magnetic lines of force in the alternating magnetic field form a loop from one magnetic pole through the metal heating plate 24 to the other magnetic pole. The magnetic lines of force cut the material, and an induced electromotive force is generated in the metal heating plate 24, thereby generating eddy currents. Since the metal heating plate 24 has a resistance characteristic, according to the Joule-Lenz law, the generated eddy currents make the metal heating plate 24 heat up. Since the metal heating plate 24 is provided with heat-conducting oil outside, the oil starts to be heated at this time. The plate 5, the first sealing gasket 7 and the first sealing plate 8 can prevent the oil from leaking from the right side of the roller core inner body 1. The second sealing gasket 10, the second sealing plate 11 and the extension plate 12 can prevent the oil from leaking from the left side of the roller core inner body 1. The cleaning convex plate 6, the first sealing gasket 7, the first sealing plate 8, the left fixed plate 9, the second sealing gasket 10, the second sealing plate 11 and the extension plate 12 are all set to high-temperature resistant materials. At this time, the heated oil transfers heat to the external heat-conducting shell, so that the external heat-conducting shell is evenly heated, and the object close to the external heat-conducting shell can be heated.

[0021] A first threaded hole is provided inside the roller core inner body 1, and a supporting screw 4 is arranged in the first threaded hole provided on the roller core inner body 1, and the right side of the supporting screw 4 is fixedly installed on the right side of the inner surface of the outer heat-conducting shell, a cleaning convex plate 6 is fixedly installed on the upper end of the right fixed plate 5, and the cleaning convex plate 6 is arranged in an arc-shaped plate-like structure, and the cleaning convex plate 6 is fitted with the inner surface of the outer heat-conducting shell, and a cylindrical groove is provided at both ends of the left fixed plate 9, and a sealing plug plate 13 is tightly fitted in the circular groove provided on the left fixed plate 9, a pressing plate 14 is fitted on the left side of the sealing plug plate 13, and the left side of the pressing plate 14 is fitted with the right side of the left fixed plate 9, the pressing plate 14 is arranged in an arc-shaped plate-like structure, and a second threaded hole is provided in the middle position of the pressing plate 14, and an adjusting screw 15 is arranged in the second threaded hole provided on the pressing plate 14, a rotating plate 16 is installed on the left side of the adjusting screw 15, a first bearing is installed in the middle position of the lower end of the rotating plate 16, and the rotating plate 1 6 is rotatably connected with the adjusting screw 15 through the first bearing, a limiting hole is provided on the rotating plate 16, and a guide rod 17 is slidably provided in the limiting hole provided on the rotating plate 16, and the guide rod 17 is fixedly installed on the pressing plate 14, a fixed rotating shaft 18 is fixedly installed in the middle position of the rotating plate 16, and a second bearing is fixedly installed on the right side of the fixed rotating shaft 18, and a receiving plate 19 is fixedly installed on the right side of the second bearing, and two receiving plates 19 are symmetrically arranged about the center of the outer heat-conducting shell, a vortex spring 21 is fixedly installed on the outer surface of the fixed rotating shaft 18, and a fixed sleeve 20 is fixedly installed on the left side of the receiving plate 19, and the vortex spring 21 is fixedly installed on the inner surface of the fixed sleeve 20, a positioning rod 22 is provided through the receiving plate 19, and the positioning rod 22 is engaged with the rotating plate 16 through the positioning groove provided on the rotating plate 16, and a positioning spring 23 is fixedly installed on the positioning rod 22, and the positioning spring 23 is fixedly installed on the receiving plate 19.

[0022] When it is necessary to filter and replace the oil and clean the inside of the device, the adjusting screw 15 is rotated, and the adjusting screw 15 begins to rotate. Because the adjusting screw 15 is connected to the pressing plate 14 through the second threaded hole opened on the pressing plate 14, as the adjusting screw 15 rotates, the pressing plate 14 begins to move, that is, the pressing plate 14 begins to move in the direction close to the rotating plate 16 under the action of the guide rod 17. At this time, the sealing plug plate 13 at the lower end position can be pulled out, and the oil flows out through the lower end of the left fixed plate 9. After the oil is discharged, the positioning rod 22 is pulled, and the positioning rod 22 begins to move in the direction away from the receiving plate 19. Because the positioning spring 23 is fixedly installed on the positioning rod 22, the positioning spring 23 begins to be stretched and deformed. Then, under the action of the vortex spring 21 restoring the deformation, the fixed shaft 18 begins to rotate. Because the rotating plate 16 is fixedly installed on the fixed shaft 18, the rotating plate 16 begins to be rotated to the water The roller core inner body 1 is in a flat state (when the vortex spring 21 is not subjected to force, the rotating plate 16 is in horizontal rotation), and then the roller core inner body 1 is rotated. Because the roller core inner body 1 is connected to the supporting screw 4 through the first threaded hole, as the roller core inner body 1 rotates, the roller core inner body 1 begins to move away from the outer heat-conducting shell. When the second sealing gasket 10 moves to the outside of the outer heat-conducting shell, the rotating plate 16 is rotated. At this time, the bristle structure provided on the rotating plate 16 fits the outer surface of the metal heating plate 24. Then, the positioning rod 22 is released. Under the action of the vortex spring 21 restoring the deformation, the vortex spring 21 begins to pull the positioning rod 22, and the positioning rod 22 is engaged with the rotating plate 16. Then, the roller core inner body 1 continues to be rotated, so that the outer surface of the metal heating plate 24 can be cleaned. Because the cleaning convex plate 6 is fixedly installed on the right fixed plate 5, the cleaning convex plate 6 begins to clean the inner surface of the outer heat-conducting shell to prevent sediment and coked oil from adhering to the device and affecting the heat conduction effect of the device.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
