The heating assembly 200 comprises: a heat-insulating component 210 and three heating components. The heat-insulating component 210 is sleeved in the roller body 100 along the axis of the roller body 100, and the heat-insulating component 210 has a receiving space 211. Each of the heating components is arranged in the receiving space 211, and two adjacent heating components are detachably connected. Each of the detection components 300 is arranged on the roller body 100, and each of the detection components 300 is connected to a corresponding heating component for detecting the temperature of a corresponding heating component. The control component is connected to each of the heating components for controlling the operation of each of the heating components. The heat-insulating component 210 can reduce the heat loss of the heating component, thereby improving the heating efficiency of the roller body 100, improving the heat utilization rate, and improving the temperature uniformity of different areas of the roller body 100. In addition, each of the detection components 300 is connected to a corresponding heating component so as to detect the temperature of a corresponding heating component, and the control component is connected to each of the heating components so as to control the operation of each of the heating components, that is, the temperature of each of the heating components can be detected and controlled separately, so as to control the temperature of the roller body 100 in a zoned manner. On the one hand, different temperatures can be set for different areas of the roller body 100, thereby increasing the applicable range of the roller structure. On the other hand, the temperature difference between different areas of the roller body 100 can be reduced, and the temperature uniformity of the roller body 100 can be improved, thereby improving the processing efficiency of the pressing roller.

[0037] In other embodiments, the number of the heating elements can be adjusted to four, five, six, seven, etc. according to actual needs, and the number of the detection elements 300 is equal to the number of the heating elements, which will not be listed here one by one.

[0038] See also Figure 3 In some embodiments, the roller body 100 is cylindrical and arranged along a preset direction. The preset direction is Figure 3 The X direction in .

[0039] See also Figure 4 In some embodiments, the heat-insulating element 210 is cylindrical and arranged along the predetermined direction. The heat-insulating element 210 includes a first end 212 and a second end 213. The first end 212 is located at an end of the heat-insulating element 210 that is closer to each of the detection elements 300. The second end 213 is located at an end of the heat-insulating element 210 that is farther from each of the detection elements 300. Both the first end 212 and the second end 213 extend outside the roller body 100.

[0040] In other embodiments, the first end 212 or the second end 213 extends outside the roller body 100 .

[0041] It can be understood that by sleeved the thermal insulation component 210 in the roller body 100 and extending the first end 212 and the second end 213 of the thermal insulation component 210 to the outside of the roller body 100, that is, in the preset direction, the thermal insulation area of ​​the thermal insulation component 210 is greater than the length of the roller body 100, thereby providing a better thermal insulation effect for the roller body 100, thereby reducing heat loss on the roller body 100 and improving the utilization rate of thermal energy.

[0042] See also Figure 4 In some embodiments, the heating assembly 200 further includes a heat conducting member 220. The heat conducting member 220 is disposed in the accommodation space 211. The shape of the heat conducting member 220 matches the shape of the accommodation space 211, and the heat conducting member 220 is provided with a mounting position. The mounting position is provided on the outer surface of the heat conducting member 220 along the predetermined direction. Each of the heating elements is mounted on the mounting position.

[0043] In some embodiments, the heat conducting member 220 is cylindrical and is made of magnesium oxide, which is a heat-conducting filler with high thermal conductivity and flame retardant properties, thus having high safety performance.

[0044] In some embodiments, the mounting position is annularly arranged on the heat conductive member 220 around the central axis of the heat conductive member 220 , and the length of the mounting position along the preset direction is smaller than the length of the heat conductive member 220 along the preset direction.

[0045] See also Figure 4 In some embodiments, the heat-insulating element 210 has a first contact surface 214. The first contact surface 214 is located on a side of the heat-insulating element 210 close to the heat-conducting element 220, and the first contact surface 214 is the inner surface of the heat-insulating element 210. Each of the heating elements is arranged in a ring around the central axis of the heat-conducting element 220 and is in contact with the first contact surface 214.

[0046] It can be understood that each of the detection components 300 respectively detects the temperature of the corresponding heating component and feeds back to the control component. The control component can simultaneously adjust the temperature of each of the heating components. On the one hand, it can meet the different temperature requirements of different areas of the roller body 100. On the other hand, through the cooperation between the control component and each of the detection components 300, the temperature difference between different areas of the roller body 100 can be reduced to improve the temperature uniformity on the roller body 100.

[0047] See also Figure 1 and Figure 2In some embodiments, the roller body 100 has a second contact surface 110. The second contact surface 110 is located on a side of the roller body 100 facing away from the heat-insulating element 210. The second contact surface 110 is the outer surface of the roller body 100. The second contact surface 110 includes three preheating zones, and each heating element is provided corresponding to at least one of the preheating zones.

[0048] In other embodiments, the number of the preheating zones can be adjusted to four, five, six, seven, etc. according to actual needs, and the number of the preheating zones is equal to the number of the heating elements, which will not be listed here one by one.

[0049] In some embodiments, the length of the mounting position along the preset direction is greater than the length of the second contact surface 110 along the preset direction, that is, the length of the heating area along the preset direction is greater than the second contact surface 110 of the roller body 100, so that the roller body 100 can be fully heated.

[0050] See also Figure 2 and Figure 3 In some embodiments, the roller structure further includes a rotating shaft 400 and a brush slip ring 600. The rotating shaft 400 is sleeved within the heat-insulating member 210 and extends outside the heat-insulating member 210 to form an extension portion 410. The extension portion 410 is located at an end of the rotating shaft 400 near the first end 212. The brush slip ring 600 is disposed on the extension portion 410.

[0051] See also Figure 2 and Figure 3 In some embodiments, the roller structure further includes a base 500. The base 500 is disposed on the extension portion 410. The brush slip ring 600 is disposed on the base 500, and the brush slip ring 600 is detachably connected to the base 500.

[0052] In some embodiments, the brush slip ring 600 and the base 500 and two adjacent heating elements are connected via a detachable connection structure, such as a snap-fit ​​structure, a magnetic structure, and the like.

[0053] See also Figure 4 and Figure 5In some embodiments, the three heating elements include: a first heating element 230, a second heating element 240, and a third heating element 250. The three preheating zones include: a first preheating zone, a second preheating zone, and a third preheating zone. The three detection elements 300 include: a first detection element 300, a second detection element 300, and a third detection element 300. The first heating element 230 is arranged corresponding to the first preheating zone and is connected to the first detection element 300. The second heating element 240 is arranged corresponding to the second preheating zone and is connected to the second detection element 300. The third heating element 250 is arranged corresponding to the third preheating zone and is connected to the third detection element 300.

[0054] In some embodiments, the first heating element 230, the second heating element 240 and the third heating element 250 are all spiral-shaped, and the first heating element 230, the second heating element 240 and the third heating element 250 are all electric heating wires, and the control element adjusts the temperature of each electric heating wire by controlling the power of each electric heating wire.

[0055] In some embodiments, the first detection element 300 , the second detection element 300 , and the third detection element 300 are all temperature sensors.

[0056] In some embodiments, the length of the first heating element 230 along the predetermined direction is greater than the length of the first preheating zone along the predetermined direction. The length of the second heating element 240 along the predetermined direction is equal to the length of the second preheating zone along the predetermined direction. The length of the third heating element 250 along the predetermined direction is greater than the length of the third preheating zone along the predetermined direction.

[0057] It is understandable that the total length of the first heating element 230 , the second heating element 240 and the third heating element 250 is greater than the length of the roller body 100 , so as to ensure the heating effect of the first heating element 230 , the second heating element 240 and the third heating element 250 on the roller body 100 .

[0058] The traditional roller structure uses thermal oil as the heating medium and transmits the thermal oil through the installation pipeline. However, the installation pipeline takes up a lot of space and has low installation efficiency. In addition, during use, the thermal oil is easy to clog the installation pipeline. There is also the problem of coking, which makes the temperature consistency of the roller structure poor. After long-term use, the middle part will become concave, the maintenance cost is high, and the continuous operation efficiency of the roller structure is affected. The roller structure in the present application heats the roller body 100 through an electric heating wire, occupies a small installation space, and can evenly heat the roller body 100. In addition, installing the electric heating wire in the heat-insulating component 210 filled with magnesium oxide can reduce heat loss during the heating process of the electric heating wire and improve the utilization rate of heat. In addition, a detection component 300 detects the temperature of a corresponding electric heating wire and can feed back to the control component. The control component can simultaneously adjust the temperature of each electric heating wire, that is, it can meet the different temperature requirements of different areas of the roller body 100. It can also reduce the temperature difference between different areas of the roller body 100 through the cooperation of the control component and each of the detection components 300, thereby improving the temperature uniformity on the roller body 100 and improving the processing efficiency of the roller structure.
