This heating device typically has a heating shroud covering the circumference of the rollers, with multiple heating plates arranged in an array on the side of the shroud facing the rollers, or multiple heating tubes arranged along the arc of the shroud. The irradiation range of the multiple heating plates in this array overlaps, leading to excessive energy consumption and significant energy waste. Furthermore, it is difficult to achieve zoned temperature control in the lateral direction with multiple heating tubes, making it impossible to ensure uniform heating for sheets with uneven lateral temperatures. Additionally, adjusting the irradiation range and angle of the heating plates and heating tubes mounted on the heating shroud is inconvenient due to the weight of the device. Summary of the Invention

Detailed Implementation
[0023] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.
[0024] This application provides a ceramic heating device, such as... Figure 1 As shown, the ceramic heating device 100 is detachably mounted on the three-roll calender 200, which includes an upper roller 40, a middle roller 50, and a lower roller 60 arranged sequentially from top to bottom. The ceramic heating device 100 is located behind the middle roller 50 and the lower roller 60 and is used to heat the sheet material that passes around the rollers from the front side of the rollers of the three-roll calender 200 to improve the quality of the final product.
[0025] like Figure 1-3As shown, the ceramic heating device 100 includes a heating mechanism 10, an adjusting mechanism 20, and a lifting mechanism 30. The heating mechanism 10 is used to irradiate the sheet material passing over the rollers to uniformly heat the sheet. The lifting mechanism 30 can drive the heating mechanism 10 to move up and down to different rollers to heat the sheet material passing over those rollers. When operators are cleaning or maintaining the rollers, the lifting mechanism 30 drives the heating mechanism 10 to avoid the rollers being cleaned, facilitating operator work. The adjusting mechanism 20 is connected between the heating mechanism 10 and the lifting mechanism 30, supporting the heating mechanism 10 and adjusting its irradiation range to improve heating efficiency and effect.
[0026] like Figure 2-4 As shown, the heating mechanism 10 includes one or more heating components 1. Each heating component 1 includes a heating housing 11 and a plurality of heating plates 12 mounted on the heating housing 11. The heating housing 11 extends in a left-right direction, and the plurality of heating plates 12 are sequentially mounted on the heating housing 11 in a left-right direction. In this embodiment, the heating mechanism 10 includes three heating components 1. In other embodiments, the number of heating components can be configured according to the diameter of the rollers of the three-roll calender, thereby adapting to the operation of different three-roll calenders.
[0027] The adjustment mechanism 20 includes a pair of arc-shaped support plates 2 arranged opposite each other, each arc-shaped support plate 2 having a circular arc groove 21. Three heating components 1 are arranged sequentially along the extension direction of the circular arc groove 21. The two ends of each heating cover 11 are respectively engaged with the circular arc groove 21 of the pair of arc-shaped support plates 2 in a way that allows both rotation and sliding. Adjustment seats 3 are respectively installed at the two ends of each heating cover 11, and adjustment bolts 4 passing through the circular arc groove 21 are connected to the adjustment seats 3. When the adjustment bolts 4 are loosened on the arc-shaped support plates 2, the adjustment bolts 4 can drive the adjustment seats 3 and the connected heating cover 11 to rotate around their own axis within the circular arc groove 21, and can move back and forth within the circular arc groove 21, thereby adjusting the position of the connected heating component 1 in the circumferential direction of the roller and the irradiation angle of the heating component 1 in the circumferential direction of the roller. When the adjusting bolt 4 is tightened on the arc-shaped support plate 2, the adjusting seat 3 and the corresponding heating component 1 are locked and fixed on the arc-shaped support plate 2, thereby fixing the irradiation range of the heating component 1.
[0028] The operator uses the adjustment mechanism 20 to precisely adjust the heating areas of the three heating components 1 in the circumferential direction of the roller according to the production requirements of the sheet, adapting to the production of different sheets. The adjustment mechanism 20 is highly flexible and convenient to use. This application reduces the number of heating components 1 installed, and adjusts the irradiation range of each heating component 1 through the adjustment mechanism 20, ensuring that the irradiation ranges of the three heating components 1 do not overlap, while meeting the heating requirements of the sheet, effectively reducing energy waste and improving energy utilization efficiency.
[0029] The lifting mechanism 30 includes a pair of lifting components 5 facing each other on the left and right. Each lifting component 5 is connected between the arc-shaped support plate 2 on the corresponding side and the three-roll calender 200. The pair of lifting components 5 are configured to drive the pair of arc-shaped support plates 2 to move synchronously in the up and down direction to adjust the position of the heating mechanism 10 in the up and down direction.
[0030] Each lifting assembly 5 includes a lifting guide column 51 and a lifting drive component 52 mounted on the three-roll calender 200, and a lifting sleeve 53 connected to the corresponding arc-shaped support plate 2. The lifting guide column 51 extends vertically, the lifting sleeve 53 slides in cooperation with the lifting guide column 51, and the lifting drive component 52 is connected to the corresponding arc-shaped support plate 2. In this embodiment, the lifting drive component is a lifting cylinder, and the cylinder rod is connected to the corresponding arc-shaped support plate 2 for raising and lowering the arc-shaped support plate 2. The sliding cooperation between the lifting sleeve 53 and the lifting guide column 51 guides the lifting and lowering of the heating mechanism 10, preventing the heating mechanism 10 from deviating and damaging the product or the rollers of the three-roll calender during the lifting and lowering process. In other embodiments, the lifting assembly can also be a screw jack, which drives the heating mechanism 10 to lift and lower via the movement of the screw.
[0031] like Figure 1 As shown, the vertical distance H of the lifting guide column 51 is greater than the center distance D between the middle roller 50 and the lower roller 60 of the three-roll calender 200, so that the heating mechanism 10 has a sufficient lifting range.
[0032] like Figure 2-4 As shown, a synchronous beam 6 is connected between the lifting sleeves 53 of a pair of lifting components 5. The synchronous beam 6 connects a pair of arc-shaped support plates 2 to ensure that the pair of arc-shaped support plates 2 can be lifted and lowered synchronously, thus avoiding uneven heating of the sheet by the heating mechanism 10 when the lifting and lowering of the pair of arc-shaped support plates 2 is inconsistent.
[0033] Each heating component 1 is equipped with a temperature control module (not shown in the figure). Each temperature control module is electrically connected to multiple heating plates 12 of the corresponding heating component 1. The temperature control module can adjust the temperature of each heating plate. In this embodiment, the temperature control module controls the temperature of the multiple heating plates 12 of each heating component 1 in groups along the left and right direction. On the one hand, this compensates for the temperature difference of the sheet in the lateral direction; on the other hand, it can reduce energy consumption. In other embodiments, the temperature control module can also adjust the temperature of the multiple heating plates 12 of the corresponding heating component 1 individually to improve the temperature control accuracy.
[0034] All heating plates 12 are ceramic heating plates. Ceramic heating plates have high thermal efficiency and uniform heating, which can effectively improve heating efficiency and heating effect.
[0035] The lifting mechanism 30 and the adjusting mechanism 20 of this application cooperate to adjust the radiation range and radiation angle of the heating mechanism 10, so as to achieve multi-angle and multi-directional heating of the sheet on the roller.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
