TECHNICAL FIELD

[0001] The present application relates to the technical field of heating roller, in particular to a precision temperature control electromagnetic heating mechanism. BACKGROUND

[0002] The heating roller is a kind of cylindrical roller that can heat itself for continuous processing and production of industrial materials. The basic principle of heating is that the electromagnetic field generated by the coil inside the electromagnetic induction heating roller body produces Joule heat by cutting the metal surface with magnetic lines, thereby achieving the effect of self-heating of the electromagnetic induction heating roller body. The roller surface exchanges heat with the processed material, and the roller body maintains the set working temperature through the closed loop temperature control system. The precision temperature control electromagnetic heating mechanism in the prior art mostly adopts a heating surface and a coil that are relatively fixed. When the coil heats the steel roller, the surface of the steel roller is unevenly heated, and at the same time, the surface of the steel roller is easily deformed, reducing the service life of the heating roller.

[0003] Therefore, it is necessary to provide a precision temperature control electromagnetic heating mechanism to solve the above technical problems. SUMMARY

[0007] The heat dissipation assembly comprises a second motor, a heat dissipation fan, and a second connecting column sleeved on the first connecting column, the second motor and the heat dissipation fan are located at the two ends of the second connecting column, respectively, and the heat dissipation fan is located in the steel roller.

[0008] The rotating assembly comprises a belt disc and a bracket sleeved on the second connecting column, the bracket is connected to the steel roller, and the belt disc and the steel roller are located at the two ends of the bracket.

[0009] The first motor drives the first connecting column to rotate the excitation rotor for uniform heating of the steel roller surface. The belt pulley connects to an external motor to rotate the bracket, which in turn rotates the steel roller to move the heated product. The second motor drives the second connecting column to rotate the cooling fan for cooling the excitation rotor.

[0010] In this invention, protective nets are provided at both ends of the steel roller.

[0011] In this invention, the transmission device is further provided with a heat insulation ring, which is located between the steel roller and the excitation rotor.

[0012] In this invention, a temperature sensing probe is also provided on one side of the steel roller.

[0055] The terms "first" and "second" used in the terminology of this invention are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as limiting the order of events.

[0056] The present invention provides a precision temperature-controlled electromagnetic heating mechanism, comprising a steel roller 11, an excitation rotor 17 located within the steel roller 11, a transmission device located at one end of the steel roller 11, and a slip ring 15 located at the other end of the steel roller 11. The transmission device includes a heat dissipation assembly 13, a drive assembly 12, and a rotation assembly 14. The drive assembly 12 includes a first motor 123 and a first connecting post 124. The first motor 123 and the excitation rotor 17 are respectively connected to the two ends of the first connecting post 124. The heat dissipation assembly 13 includes a second motor 131, a cooling fan 133, and a second connecting post 132 sleeved on the first connecting post 124. The second motor 131 and the cooling fan 133 are respectively located at the two ends of the second connecting post 132. The cooling fan 133 is located within the steel roller 11.

[0057] The rotating assembly 14 includes a belt pulley 141 and a bracket 142 sleeved on the second connecting column 132. The bracket 142 is connected to the steel roller 11. The belt pulley 141 and the steel roller 11 are located at both ends of the bracket 142. The first motor 123 drives the first connecting column 124 to drive the excitation rotor 17 to rotate, which is used to uniformly heat the surface of the steel roller 11. The belt pulley 141 is connected to an external motor to drive the bracket 142 to rotate. The bracket 142 drives the steel roller 11 to rotate, which is used to move the heated product. The second motor 131 drives the second connecting column 132 to drive the cooling fan 133 to rotate, which is used to dissipate heat from the excitation rotor 17.

[0058] The steel roller 11 is used to heat or dry the surface of the product. The excitation rotor 17 is located inside the steel roller 11 and is used to heat the steel roller 11. The transmission device is used to drive the steel roller 11 to rotate and drive the excitation rotor 17 to generate heat. The first motor 123 is connected to the first connecting post 124, and the first connecting post 124 is connected to the excitation rotor 17. The second connecting post 132 is sleeved on the first connecting post 124. The second motor 131 and the cooling fan 133 are connected to the two ends of the second connecting post 132. The bracket 142 is sleeved on the second connecting post 132. The belt pulley 141 and the steel roller 11 are respectively connected to both ends of the bracket 142. The slip ring 15 is connected to the other end of the steel roller 11. When the steel roller 11 is heated, firstly, the slip ring 15 is connected to an external high-frequency current, and the second motor 131 is started. The second motor 131 drives the second connecting post 132 to rotate. Since the second connecting post 132 is sleeved on the first connecting post 124, the first connecting post 124 stops when the second connecting post 132 rotates. Without moving, the second connecting column 132 drives the cooling fan 133 inside the steel roller 11 to circulate air inside the steel roller 11. Further, the first motor 123 rotates, driving the first connecting column 124 to rotate. The first connecting column 124 drives the excitation rotor 17 to rotate. When the excitation rotor 17 rotates, it generates an induced magnetic field with the external high-frequency current, which heats the steel roller 11. During the rotor rotation, the surface temperature of the steel roller 11 is made uniform, preventing one end from being too hot or too cold. Further, the belt pulley 141 is connected to an external drive motor via a synchronous belt. The drive motor drives the belt pulley 141 to rotate, which in turn drives the bracket 142 to rotate. The bracket 142 drives the steel roller 11 to rotate, thus moving the product while the heated steel roller 11 is heating it. On the one hand, this effectively prevents uneven heating or drying of the product. On the other hand, the uniform heating of the steel roller 11 surface makes it less prone to deformation, thus improving the service life of the steel roller 11.

[0059] Both ends of the steel roller 11 are equipped with protective nets 111, which are used to prevent foreign objects from entering the interior of the steel roller 11.

[0060] The transmission device is also equipped with a heat insulation ring 171, which is located between the steel roller 11 and the excitation rotor 17. The heat insulation ring 171 is used to protect the excitation rotor 17 and prevent the excitation rotor 17 from overheating.

[0061] A temperature sensor 16 is also provided on one side of the steel roller 11. The temperature sensor is used to monitor the surface temperature of the steel roller 11.

[0062] The drive assembly 12 is also provided with an L-shaped fixing plate 121 and a connecting plate 122. The fixing plate 121 is located below the first motor 123. The fixing plate 121 and the temperature probe 16 are located at both ends of the connecting plate 122. The temperature probe 16 is connected to the connecting plate 122. The fixing plate 121 is used to fix the first motor 123, and the connecting plate 122 is used to fix the temperature probe 16. The connecting plate 122 is fixed on the fixing plate 121.

[0063] The excitation rotor 17 includes a third connecting post 172, a plastic steel shaft 173 fixed on the third connecting post 172, and a coil 174 wound on the plastic steel shaft 173. The third connecting post 172 is used to install the plastic steel shaft 173, and the plastic steel shaft 173 is used to install the coil 174. Plastic steel has good heat preservation effect, affordable price, high density, and anti-aging properties.

[0064] The bracket 142 includes a fourth connecting post 1421 sleeved on the second connecting post 132 and a cross plate 1422 connected to the fourth connecting post 1421. The cross plate 1422 is connected to the steel roller 11. The fourth connecting post 1421 is sleeved on the second connecting post 132 and is used to fix the cross plate 1422 and the belt pulley 141.

[0065] Working principle:

[0066] The precision temperature-controlled electromagnetic heating mechanism includes a steel roller 11, a transmission device and a slip ring 15 respectively connected to both ends of the steel roller 11, and an excitation rotor 17 connected inside the steel roller 11. Protective nets 111 are provided at both ends of the steel roller 11, and a temperature sensor 16 is also provided on one side of the steel roller 11. The transmission device includes a drive assembly 12, a heat dissipation assembly 13, and a rotation assembly 14. The drive assembly 12 includes an L-shaped fixed plate 121, a connecting plate 122 connected to the fixed plate 121, a first motor 123 connected to the fixed plate 121, and a first connecting post 124 connected to the first motor 123. The temperature sensor 16 is fixed to the connecting plate 122. The heat dissipation assembly 13 includes a second connecting post 124 sleeved on the first connecting post 124. The system includes a column 132, a second motor 131 connected to both ends of the first connecting column 124, and a cooling fan 133. The cooling fan 133 is located inside the steel roller 11. The transmission assembly includes a pulley 141, a bracket 142, and a heat insulation ring 171. The heat insulation ring 171 is located between the steel roller 11 and the excitation rotor 17. The pulley 141 and the steel roller 11 are fixed to both ends of the bracket 142. The bracket 142 includes a fourth connecting column 1421 sleeved on the second connecting column 132 and a cross plate 1422 fixed on the fourth connecting column 1421. The excitation rotor 17 includes a third connecting column 172 connected to the first connecting column 124, a plastic steel shaft 173 fixed on the third connecting column 172, and a coil 174 wound on the plastic steel shaft 173.

[0067] When the steel roller 11 is heated, firstly, the slip ring 15 is connected to an external high-frequency current, and the second motor 131 is started. The second motor 131 drives the second connecting post 132 to rotate. Since the second connecting post 132 is sleeved on the first connecting post 124, the first connecting post 124 remains stationary when the second connecting post 132 rotates. The second connecting post 132 drives the cooling fan 133 to rotate, allowing air circulation inside the steel roller 11 and cooling the excitation rotor 17. Since protective nets 111 are provided on both sides of the steel roller 11, the protective nets 111 allow air to enter the steel roller 11 from the outside and prevent debris from entering the steel roller 11. Furthermore, the first motor 123 is started, driving the first connecting post 124 to rotate, and the first connecting post 124 drives the excitation fan 133 to rotate. Rotor 17 rotates, and the excitation rotor 17 generates an induced magnetic field with the high-frequency current, thereby heating the steel roller 11. Because the excitation rotor 17 is rotating, the heating of the steel roller 11 by the excitation rotor 17 is more uniform. Furthermore, the external drive motor drives the pulley 141 to rotate, and the pulley 141 drives the fourth connecting column 1421 to rotate. The fourth connecting column 1421 drives the steel roller 11 to rotate through the cross plate 1422, so that the heated product can move backward. The steel roller 11 is continuously heated by the rotation of the excitation rotor 17, and the surface of the steel roller 11 is heated more uniformly. On the one hand, it can effectively prevent uneven heating or drying of the product. On the other hand, the uniform heating of the surface of the steel roller 11 can prevent the surface of the steel roller 11 from deforming, thereby improving the service life of the steel roller 11.

[0068] In this preferred embodiment, the precision temperature-controlled electromagnetic heating mechanism drives the first connecting column of the first motor to rotate the excitation rotor. The excitation rotor and the high-frequency current generate an induced magnetic field to heat the steel roller, thereby heating the surface of the steel roller. During the rotation of the rotor, the surface heat of the steel roller is made uniform. On the one hand, it can effectively prevent uneven heating or drying of the product. On the other hand, the uniform heating of the steel roller surface can make the steel roller surface less prone to deformation, thus improving the service life of the steel roller.

[0069] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
