A heating device 200 is disposed within the cavity. In this embodiment, the heating device 200 is located in the lower portion of the chamber. The heating device 200 may be, for example, a silicon carbide rod. The silicon carbide rod has good temperature characteristics, and the silicon carbide rod used as a heat generating element has high heating efficiency and low power consumption. Two electrodes can be arranged at two ends of the silicon carbide rod. The two electrodes are connected to a transformer by wires.

The first supporter 310 is rotatably provided on the first sidewall 110 of the furnace body 100 using a bearing 330, and the second supporter 320 is rotatably provided on the second sidewall 120 of the furnace body 100 using a bearing 330. The first sidewall 110 and the second sidewall 120 are two opposite sidewalls of the furnace body 100. Both ends of the glass forming roll R are mounted to the first mount 310 and the second mount 320, respectively. Alternatively, as shown in fig. 2, a plurality of glass forming rolls R may be arranged side by side in the cavity. Accordingly, a plurality of pairs of the first and second holders 310 and 320 are provided on the first and second sidewalls 110 and 120.
The first support 310 may be cylindrical in shape, extending from within the cavity to outside the cavity. The first support 310 may include an inner end 311 located within the cavity of the furnace body 100 and an outer end 312 located outside the cavity. The inner end 311 has a receiving portion provided therein for receiving the glass forming roll R. In the examples shown in the present disclosure, the receiving portion is a notch. The notch extends from the end face of the inner end 311 toward the outer end 312 of the first support 310 and is shaped and sized to match the shape and size of the end of the glass forming roll R. In other words, the inner end 311 is tubular. An engaging portion for forming an interlocking structure with the end of the glass forming roll R is also provided on the receiving portion. In this embodiment, the engagement portion is a groove 313 extending radially outward from the periphery of the recess. The grooves 313 cooperate with projections provided at the ends of the glass forming roll R to form an interlocking structure. If necessary, a plurality of grooves 313 may be provided at the periphery of the notch, and a plurality of projections may be provided in the circumferential direction at the end of the glass forming roll R, respectively. Similarly, the engaging portion may be a projection extending radially inward from the periphery of the recess, and the end of the glass forming roll R is provided with a groove to be fitted therewith. Other interlocking structures are also contemplated, for example, the engagement portions may be spring pins with corresponding pin holes in the ends of the glass forming roll R that are inserted into the pin holes of the glass forming roll R when the ends of the glass forming roll R are inserted into the inner end 311 of the first pedestal 310 to form the interlocking structure. Alternatively, the engaging portion and the end portion of the glass forming roll R may be provided with pin holes, and a pin may be inserted into the pin holes of the engaging portion and the end portion of the glass forming roll R from the radially outer side of the first holder 310 to form an interlocking structure.
The outer end 312 of the first support 310 is provided with a gear 314. the gear 314 may be integrally formed with the outer end 312 or fixedly mounted to the outer end 312.

The other end of the second support 320 is received in the bearing 330, but does not extend to the outside of the furnace body. Since the end of the first support 310 has a structure to interlock with the end of the glass forming roll R, the inner end of the second support 320 may not have an interlocking structure. But interlocking structures similar to those of the inner end of the first holder 320 may be provided at the inner end of the second holder 320, if desired.
The driving mechanism 400 is used for driving the supporting mechanism 300 to rotate, and further driving the glass forming roller R installed on the supporting mechanism 300 to rotate. The glass forming roller R is rotated when being heated, so that the heating area can be increased, the heating efficiency is improved, the heat treatment operation of the material can be more uniform, and the local stress is reduced. The drive mechanism 400 may employ a motor, such as, but not limited to, a servo motor.
Referring to fig. 1, in some embodiments of the present disclosure, the apparatus further includes a temperature sensor 500 and a controller (not shown). The temperature sensor 500 is provided in the cavity of the furnace body 100 and is used to collect temperature data within the cavity. The temperature data is sent to the controller, which adjusts the heating operation of the heating device 200 based on the temperature data.

A sealing ring 340 surrounds the outer surface of the first support 310 and is attached to the outer surface of the first sidewall 110, and the sealing ring 340 is used for closing the gap between the first sidewall 110 and the first support 310. The seal ring 340 may be a wear resistant ceramic seal ring.
When the glass forming roll R is heat-treated using the glass forming roll heat treatment apparatus according to the present disclosure, both ends of the glass forming roll R are mounted to the first mount 310 and the second mount 320 of the support mechanism 300, ensuring that the glass forming roll R and the support mechanism 300 are locked. The set heating temperature, the set heat-retaining time, and the rotation speed of the driving mechanism are input into the controller, and the driving mechanism 400 is started. The heating device 200 heats the cavity of the furnace body 100 to a set temperature, and during the heating, the supporting mechanism 300 drives the glass forming roll R to rotate around the axis of the forming roll R under the action of the driving mechanism 400 and uniformly heats the glass forming roll R. For example, the glass forming roller R can be heated to 700-800 ℃ and kept for 18-24 hours, so that the stress and moisture in the material of the forming roller can be effectively removed, and the thermal stability of the forming roller can be improved.
