[0016] Compared with the related art, a heating device for treating the surface cracking and hardening of a glass mold proposed by the present utility model has the following beneficial effects:

[0017] In the present utility model, for a heating device for treating surface cracking and hardening of a glass mold, through the provided transmission heating assembly, by starting the rotation of the second motor, using the meshing transmission of the third bevel gear and the bevel teeth, and then driving the rotation of the rotating ring, the rotating ring drives the rotation of the rotating shaft through the meshing transmission of the bevel teeth on it and the first bevel gear. Further, the rotation of the fourth bevel gear is driven by the meshing action of the second bevel gear at the upper end of the rotating shaft and the fourth bevel gear. Then, the fourth bevel gear drives the rotation of the rotating cylinder. Since the rotating cylinder is in a screwed connection with the side wall of the heating cylinder, when the rotating cylinder rotates, the distance between its inner end and the wall of the heating cylinder is adjusted. With the rotating connection relationship of the fourth bevel gear slidably mounted on the rotating cylinder with the rear support cylinder seat, its position with the second bevel gear remains unchanged and always maintains a meshing relationship. When the rotating cylinder rotates and relatively slides with the fourth bevel gear, the torque is transmitted by the limiting key and the limiting groove and maintains a relative sliding relationship. At this time, it is set to change the distance between the gas nozzle and the glass mold, thereby adjusting the distance of the flame of the gas nozzle from the glass mold during the heating treatment, and indirectly adjusting the heating temperature. In addition, the rotating disc at the bottom of the heating cylinder drives the rotation of the glass mold for rotational heating, making the heating of the glass mold more uniform, avoiding cracking caused by temperature stress, and improving the practicability.

[0026] In this mode, a support leg 2 is fixedly connected to the side of the heating cylinder 1.

[0027] Through the above setting, the support leg 2 provides a supporting function for the heating cylinder 1.

[0028] In this mode, a support seat 7 is fixedly installed at the position corresponding to the rotating shaft 8 on the side of the heating cylinder 1, and the rotating shaft 8 rotatably passes through the support seat 7.

[0029] Through the above settings, the support base 7 provides a rotational connection point for the rotating shaft 8.

[0030] In this method, the second motor 9 is fixedly installed on the inner side of the support leg 2.

[0031] In this method, a bearing 13 is provided at the rotational connection between the rotary drum 10 and the rectangular cavity seat 12.

[0032] Through the above settings, the setting of the bearing 13 reduces the frictional force at the rotational connection between the rotary drum 10 and the rectangular cavity seat 12, reducing frictional losses.

Start the first motor 4 to rotate, which can drive the turntable 3 to rotate, and then drive the glass mold 5 to rotate inside the heating cylinder 1. Subsequently, introduce gas from the gas pipe 15. Since the gas pipe 15 is connected to the inner metal pipe seat 16, the gas is input into the metal pipe seat 16 through the gas pipe 15 and finally ejected from the gas nozzle 17. At this time, start the spark plug in the gas nozzle 17 to ignite, so that a flame is ejected from the gas nozzle 17 to heat the inner glass mold 5. During the heating process, the second motor 9 can be started to drive the third bevel gear 91 to rotate at the same time. The third bevel gear 91 is used to drive the rotating ring 6 to rotate. The rotating ring 6 drives the rotating shaft 8 to rotate through the engagement of the bevel teeth 61 on it with the first bevel gear 81. Further, the second bevel gear 82 at the upper end of the rotating shaft 8 engages with the fourth bevel gear 11 to drive the fourth bevel gear 11 to rotate. The fourth bevel gear 11 drives the rotating cylinder 10 to rotate. Since the rotating cylinder 10 is screwed to the side wall of the heating cylinder 1, when the rotating cylinder 10 rotates, the distance between its inner end and the barrel wall of the heating cylinder 1 is adjusted, further adjusting the distance between the flame ejected from the gas nozzle 17 and the glass mold 5, and indirectly adjusting the heating temperature.
