Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1

[0025] like Figure 1 As shown, this embodiment provides a glass hot end thickness gauge, including a thickness gauge body 1 and a cooling mechanism 2.

[0026] like Figure 1As shown, the thickness gauge body 1 is placed in the cooling mechanism 2.

[0027] like Figure 1 , Figure 2 As shown, the cooling mechanism 2 includes a cooling jacket 21, a liquid inlet pipe 22, an air inlet pipe 23, a heat-insulating cushion 24, a first ceramic ring 25, a heat-insulating glass 26, a support jacket 27, a second ceramic ring 28, and a protective cover plate 29. A placement channel 211 is provided through the middle of the cooling jacket 21. A thickness gauge body 1 is placed in the placement channel 211. The output end of the thickness gauge body 1 is placed at the bottom end of the cooling jacket 21. The thickness gauge body 1 is led out from the top end of the cooling jacket 21 through a cable.

[0028] like Figure 1 , Figure 2 As shown, the cooling jacket 21 is double-layered, and the double-layer materials of the cooling jacket 21 are hollowed out for placing liquid for circulating cooling. A liquid inlet 212 is provided on one side of the top of the cooling jacket 21, and a liquid inlet pipe 22 is fixed at the liquid inlet 212 in the cooling jacket 21. The liquid inlet pipe 22 leads to the output end of the bottom end of the cooling jacket 21 close to the thickness gauge body 1, and the output end of the liquid inlet pipe 22 is limited by a support seat 221. The output end of the liquid inlet pipe 22 can transport the coolant to the output end of the thickness gauge body 1 and then put the liquid into the hollow groove of the cooling jacket 21, and a liquid outlet 213 is provided on the other side of the top of the cooling jacket 21; an air inlet pipe 23 is fixed near the liquid outlet 213 in the cooling jacket 21, and the input end of the air inlet pipe 23 is located at the top of the cooling jacket 21, and the output end of the air inlet pipe 23 leads to the bottom end of the cooling jacket 21;

[0029] like Figure 1 , Figure 2 As shown, the bottom end of the cooling sleeve 21 is provided with a protective cover plate 29, a second ceramic ring 28, a support sleeve 27, an insulating glass 26, a first ceramic ring 25, and an insulating cushion 24 in sequence from bottom to top. The support sleeve 27 is fixed to the bottom of the cooling sleeve 21 by bolts. The insulating glass 26, the first ceramic ring 25, and the insulating cushion 24 are placed in sequence above the support sleeve 27. The output end of the thickness gauge body 1 is placed on the insulating cushion 24. The first ceramic ring 25 and the insulating cushion 24 are both opened in the middle. The insulating glass 26 is a special transparent glass that is resistant to high temperature and heat insulation (the prior art), so that the thickness gauge body 1 can be placed on the outer surface of the cooling sleeve 21.
