Technical Field

[0001] The utility model relates to the technical field of glass production, in particular to a glassware baking furnace. Background Art

[0002] After decoration, porcelain must be fired in a furnace to ensure that the patterns are firmly attached to the glaze surface of the porcelain. This firing process is called "baking". Glassware is becoming more and more popular among consumers. In order to improve the aesthetics of glassware, in the existing glass baking process, it is necessary to first apply flower paper on the surface of the glassware, then send the glassware to a high-temperature kiln for high-temperature baking, and finally take the baked glassware out of the high-temperature kiln and let it stand for natural cooling.

[0003] The existing baking device mainly adopts electric heating wire for heating. The two side walls of the inner shell of the furnace body are provided with several through holes, each of which is equipped with electric heating wire. When working, the electric heating wire is energized and heated to heat the inner shell and the furnace cavity to a suitable baking temperature, and the heat energy of the electric heating wire and the furnace wall is sent to the furnace of the inner shell to achieve the purpose of baking the glass bottles. However, this results in a higher temperature for the glass bottles located on both sides of the furnace body, while the temperature of the glass bottles located in the middle of the furnace body is lower. The uneven heating of the glass bottles will affect the baking effect, and the temperature inside the glass bottles cannot be effectively adjusted. When the temperature is too high, the glass bottles are prone to bursting, which greatly reduces the safety of the device. How to invent a glassware baking furnace to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

The outer wall of the inner gear ring 10 is fixedly connected to the fixed plate 12, and the lower side wall of the fixed plate 12 is fixedly connected to the support column 11, and the lower end of the support column 11 is fixedly connected to the inner wall of the lower end of the furnace body 2; the electric heating wire 13 is sleeved on the outer wall of the electric heating rod 14, and the electric heating rod 14 is arranged in a "T" shape. One end of the electric heating rod 14 is fixedly connected to the upper side wall of the fixed plate 12, and the two ends of the electric heating wire 13 are fixedly connected to the fixed plate 12 and the electric heating rod 14 respectively.

[0027] It should be noted that when baking glassware, the furnace door 4 is first opened to place the glassware to be processed into the slot 18 inside the placement tray 15 for fixing, and then the furnace door 4 is closed. In addition, the controller 3 is respectively connected to the fan 7, the electric turntable 8, the electric heating wire 13 and the electric heating rod 14.

[0029] It should be noted that: when the temperature inside the furnace body 2 is too high, the heat will be transferred to the inside of the telescopic airbag 20 through the heat conducting rod 19. When the telescopic airbag 20 is subjected to excessive heat, it will begin to expand, and then the upper end of the telescopic airbag 20 will begin to move upward, and finally drive the extrusion block 21 to squeeze the contact switch 22. When the contact switch 22 is triggered, the fan 7 will be automatically started. After the fan 7 works, part of the heat inside the furnace body 2 will be discharged through the connecting pipe 6, thereby reducing the temperature inside the furnace body 2.
