[0042] At present, in the transmission type heating equipment, a heating roller is usually used to heat the product passing through the roller surface of the heating roller so that the product can meet the corresponding process requirements. The heating roller in the traditional technology usually has an inner cavity inside the heating roller, and then the heat is transferred to the roller surface of the heating roller through the action of heat transfer oil, thereby heating the product; however, the heating method of heating oil has a relatively complex internal structure of the heating roller, and it takes a long time to reach the preset requirements. For example, it generally takes about 1 hour to heat up to 100℃, which is inconvenient in application.

[0043] In view of the above technical problems, the present embodiment mainly provides a heating roller and a heating device thereof, which can have a higher heating response rate and a better overall use effect.

[0044] like Figure 1-4 As shown, a heating roller provided according to some embodiments of the present application includes a heated cylinder 1 and an electrically controlled heating plate 2, wherein the outer surface of the heated cylinder 1 is the roller surface of the heating roller, the electrically controlled heating plate 2 is arranged inside the heated cylinder 1, and the outer wall surface of the electrically controlled heating plate 2 is arranged relative to the inner wall surface of the heated cylinder 1 to form heat transfer.

[0045] In some embodiments, the heated cylinder 1 can be set to be transparent; for example, it can be made of glass or transparent plastic. By setting the heated cylinder 1 to be transparent, the operation of the electrically controlled heating plate 2 can be more intuitively controlled.

[0046] By setting the electrically controlled heating plate 2 and making the electrically controlled heating plate 2 and the heated cylinder 1 relatively arranged to form a heat transfer form, the heated cylinder 1 can be directly heated by the electrically controlled heating plate 2, and the electrically controlled heating method can have a faster response rate, a rapid temperature rise, and a better use effect than the heating method using heat transfer oil.

[0047] In some embodiments, the electrically controlled heating plate 2 is a plate-shaped structure made of graphene.

[0048] In some application examples, compared with the heating method of heat transfer oil, the electrically controlled heating plate 2 can be heated to 100° C. in about 10 seconds; and the temperature error in the application can be ≤1° C.

[0049] By using graphene material to make the electrically controlled heating plate 2, the electrically controlled heating plate 2 can have higher heating efficiency, so as to better transfer heat with the heated cylinder 1, thereby achieving rapid temperature rise on the surface of the heated cylinder 1 and better temperature controllability.

[0050] As one application example, a preset heating area 11 is provided on the heated cylinder 1 , and the shape of the electrically controlled heating plate 2 is configured to match the shape of the preset heating area 11 .

[0051] In some embodiments, the heating effect can be designed according to the actual heating requirements of the heating roller; for example, when only individual areas of the roller surface of the heating roller need to have a heating effect, the electrically controlled heating plate 2 can be provided only for the individual areas.

[0052] In some embodiments, when the heating roller needs to be fully engaged in heating operation, that is, the surface of the heated cylinder 1 needs to have a heating effect, the electrically controlled heating plate 2 can also be configured as a cylindrical structure and coaxially arranged inside the heated cylinder 1, thereby achieving all-round heating.

[0053] By setting the shape of the electrically controlled heating plate 2 to be compatible with the shape of the preset heating zone 11 , it is possible to facilitate the adaptability setting between the electrically controlled heating plate 2 and the preset heating effect to meet different process requirements.

[0054] As an application example, the electrically controlled heating plate 2 can rotate synchronously with the preset heating area 11 .

[0055] In some embodiments, the electrically controlled heating plate 2 can correspond to the preset heating zone 11 and be directly attached to the inner side surface of the heated cylinder 1 , thereby achieving synchronous movement between the electrically controlled heating plate 2 and the preset heating zone 11 .

[0056] In some embodiments, the electrically-controlled heating plate 2 can be arranged to be coaxial with the heated cylinder 1, and the electrically-controlled heating plate 2 is arranged to be directly opposite to the preset heating zone 11, thereby achieving synchronous movement between the electrically-controlled heating plate 2 and the preset heating zone 11.

[0057] In some embodiments, when the cylinder surface of the heated cylinder 1 is set to the preset heating zone 11, the electrically controlled heating plate 2 can be set to a fixed form and only the heated cylinder 1 can be rotated; or the electrically controlled heating plate 2 can be set to rotate simultaneously with the heated cylinder 1.

[0058] By arranging the electrically controlled heating plate 2 to rotate synchronously with the preset heating zone 11 , the heating stability of the electrically controlled heating plate 2 on the preset heating zone 11 can be improved.

[0059] As one application example, a rotating shaft 12 is provided corresponding to the heated cylinder 1 , and the heated cylinder 1 and the electrically controlled heating plate 2 are both provided on the rotating shaft 12 .

[0060] In some embodiments, Figure 1 As shown, there is a gap between the electrically controlled heating plate 2 and the heated cylinder 1; and / or, there is a gap between the electrically controlled heating plate 2 and the rotating shaft 12; by reserving the gap inside the heated cylinder 1, it can be convenient for subsequent connection with the temperature control system to better control the surface temperature of the heated cylinder 1.

[0061] In some embodiments, Figure 1 , 2 As shown, both ends of the heated cylinder 1 are provided with cylinder end plates 13 , and the cylinder end plates 13 are sleeved on the rotating shaft 12 and fixed by locking nuts 14 .

[0062] In some embodiments, a bearing 15 is provided between the cylinder end plate 13 and the rotating shaft 12 to improve the rotation coordination of the heated cylinder 1 .

[0063] In some embodiments, Figure 1 , 3 As shown, heating plate brackets 21 are provided at both ends of the electrically controlled heating plate 2, and the heating plate brackets 21 are sleeved on the rotating shaft 12 and located on the inner side of the cylinder end plate 13. At this time, an inner cavity is formed between the electrically controlled heating plate 2 and the cylinder end plate 13.

[0064] By setting the rotating shaft 12, it is easy to realize the coaxial installation of the heated cylinder 1 and the electrically controlled heating plate 2 on the rotating shaft 12, and after installation, the overall installation structure can be simpler.

[0065] As an example of one application, Figure 4As shown, a plurality of channels are provided in the rotating shaft 12 , one end of the channel passes through the end of the rotating shaft 12 , and the other end of the channel passes through the side of the rotating shaft 12 and is located in the inner cavity of the heated cylinder 1 .

[0066] In some embodiments, the channel includes a horizontal section 121 and a connecting section 122, the horizontal section 121 is coaxially arranged with the rotating shaft 12, and one end of the horizontal section 121 passes through the end of the rotating shaft 12, and the other end of the horizontal section 121 extends into the interior of the heated cylinder 1; the connecting section 122 is connected with the horizontal section 121, and passes through the side of the rotating shaft 12 to connect with the interior of the heated cylinder 1.

[0067] In some embodiments, the number of the connecting sections 122 can be set to one or more.

[0068] By setting the hole, the setting of the rotating shaft 12 can be further utilized to facilitate the expansion setting of more application functions.

[0069] As an example of one application, Figure 1 , 3 As shown in FIG. 4 , the channel includes a first channel 123 , in which a wire 22 is passed, one end of the wire 22 is connected to the electric-controlled heating plate 2 , and the other end of the wire 22 extends from the end of the rotating shaft 12 .

[0070] The first hole 123 is provided to facilitate the installation of the wire 22 , thereby controlling the operation of the electric-controlled heating plate 2 .

[0071] As an application example, the channel includes a second channel 124, and the second channel 124 is connected to a temperature control system.

[0072] In some embodiments, the temperature control system transports the cooling medium to the interior of the heated cylinder 1 through the second channel 124, and the cooling medium can flow through the gap between the electrically controlled heating plate 2 and the heated cylinder 1, and the gap between the electrically controlled heating plate 2 and the rotating shaft 12, thereby achieving temperature control operation.

[0073] The second hole 124 can facilitate the cooling medium in the temperature control system to enter the heated cylinder 1, thereby playing a role in temperature control and further improving the application effect of the heating roller.

[0074] In some embodiments, at least one of the cylinder end plates 13 is provided with an exhaust valve 131 .

[0075] By providing the exhaust valve 131 , it is possible to facilitate regulation of the air pressure inside the heated cylinder 1 , so that the operation of the electrically controlled heating plate 2 and the temperature control system can be more stable and reliable.

[0076] As an example of one application, Figure 1 As shown, rotating joints 16 are connected to both ends of the rotating shaft 12 .

[0077] By providing the rotary joint 16 , it is possible to facilitate the functional connection between an external device or system and the rotating shaft 12 , thereby preventing the rotational movement of the rotating shaft 12 from affecting the application of the connection function.

[0078] In addition, this embodiment also provides a heating device, on which at least one heating roller as described above is arranged.

[0079] By applying the heating roller provided in the embodiment of the present application to the heating device, the heating effect of the heating device can be improved, thereby facilitating the improvement of the molding quality of the corresponding product.
