[0004] During use of the above-mentioned utility, the guide tube is located below the glass ribbon. By adjusting the different positions of the guide tube, the measuring point is adjusted. When the glass is annealed, the temperature in the annealing furnace is high. Not only is the spacing between multiple guide tubes small, but the spacing between the guide tube and the roller is also small. The guide tube is easily deformed and bent at high temperatures, which may not only damage the thermocouple wire inside it and affect the measurement accuracy, but also easily rub against the roller, affecting production and causing damage. Utility Model Content

[0005] In response to the above-mentioned existing technology, the technical problem to be solved by the present invention is that the distances between multiple guide tubes are relatively close, and they are prone to deformation and bending at high temperatures, which may not only damage the thermocouple wires inside and affect the measurement accuracy, but also easily rub against the rollers, affecting production and causing damage.

[0006] The cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame. The cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame. The cam is fixedly mounted on the support frame. The cam is fixedly mounted on the support frame.

[0007] In the above-mentioned movable thermocouple temperature measuring device under the annealing kiln plate, the guide tube is made of high-temperature resistant material, so that the guide tube has high-temperature resistance. At the same time, a fixed plate and a support assembly are provided to support and limit the multiple guide tubes, so that the guide tube is not easily deformed and twisted due to high temperature, thereby effectively avoiding damage to the internal thermocouple wire caused by deformation of the guide tube, and effectively avoiding friction with the roller, thereby effectively improving the stability of the thermocouple temperature measuring assembly during temperature measurement.

[0008] As a further improvement of the present application, the guide tube is L-shaped, the lengths of the multiple guide tubes are different, and the upper ends of the multiple guide tubes are located in the same horizontal plane.

[0009] As a further improvement of the present application, a plurality of guide tubes are evenly distributed up and down, and the guide tubes are made of corundum material.

[0010] As another improvement of the present application, the support shell includes four arc-shaped plates fixedly connected to each other, the outer surfaces of the arc-shaped plates are fixedly connected to the inner walls of the support frame, and the cross plates are fixedly connected to the inner walls of the arc-shaped plates.

[0011] As another improvement of the present application, a support ring is fixedly embedded in the front end of the guide tube, the support ring is movably sleeved on the outer surface of the thermocouple wire, and scale lines are printed on the outer surface of the guide tube.

[0012] To sum up, in actual application, the longitudinal position of the guide tube can be adjusted by pulling the guide tube, and during the movement of the guide tube, the fixed plate limits the outer surface of the guide tube, and the fixed ring moves with the movement of the guide tube, thereby driving the support plate and the slide plate to move, and the limiting rod moves in the slide groove, thereby limiting the curved side of the guide tube. Under high temperature, the fixed plate and the support plate support the guide tube, making it difficult for the guide tube to deform and twist, thereby effectively avoiding damage to the internal thermocouple wire caused by deformation of the guide tube, and effectively avoiding friction with the roller, thereby effectively improving the stability of the thermocouple temperature measuring component during temperature measurement.

[0022] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0023] The first implementation method:

[0024] Figure 1 、 Figure 2 and Figure 3 The figure shows: a movable thermocouple temperature measuring device under the annealing furnace plate, including a U-shaped mounting frame 1, the inner bottom wall of the mounting frame 1 is fixedly connected to a support frame 2, the inner cavity of the support frame 2 is fixedly connected to a support shell 3, and a cross plate 4 is fixedly connected to the support shell 3. The support shell 3 includes four arc plates fixedly connected to each other, the outer surface of the arc plate is fixedly connected to the inner wall of the support frame 2, and the cross plate 4 is fixedly connected to the inner wall of the arc plate. The cross plate 4 can support and fix the four arc plates, thereby effectively improving the stability of the support shell 3. When subjected to extrusion force, the extrusion force can be dispersed into the arc plate, effectively improving the anti-deformation ability of the support frame 2. An adjusting groove 5 is opened at the front end of the mounting frame 1 to facilitate the staff to pull the guide tube 7 through the adjusting groove 5. A plurality of fixed plates 6 are fixedly connected to the upper end of the support frame 2. The longitudinal section of the fixed plate 6 is triangular, which effectively improves the stability of the guide tube 7 when sliding.

[0025] Figure 1 、 Figure 4 and Figure 5It is shown that: a guide tube 7 is provided on the rear side of the fixed plate 6, and the front end of the guide tube 7 is movable through the fixed plate 6 and the adjustment groove 5 in sequence. A thermocouple wire 9 is provided at the front end of the guide tube 7, and the temperature below the glass ribbon can be measured through the thermocouple wire 9. The rear end of the thermocouple wire 9 is movable through the guide tube 7. The guide tube 7 is L-shaped, and the lengths of the multiple guide tubes 7 are different. The upper ends of the multiple guide tubes 7 are located in the same horizontal plane, which is convenient for temperature measurement at different positions under the glass ribbon. The multiple guide tubes 7 are evenly distributed up and down, and the guide tubes 7 are made of corundum material. The hardness and melting point of corundum material are relatively high, and it is not easy to be deformed due to high temperature, thereby effectively improving the stability of the guide tube 7 during use.

[0026] Figure 1 、 Figure 4 and Figure 6 It is shown that: the outer surface of the guide tube 7 is fixedly sleeved with a support assembly, which includes a fixing ring 10 fixedly sleeved on the outer surface of the guide tube 7, and the lower end of the fixing ring 10 is fixedly connected to two support plates 11, and the lower ends of the two support plates 11 are jointly fixedly connected to a slide plate 12, and a triangle is formed between the two support plates 11 and the slide plate 12, thereby stably supporting the fixing ring 10. At the same time, the fixing plate 6 and the support assembly can fix the spacing between multiple guide tubes 7. During the process of adjusting the guide tube 7, the guide tube 7 is not easy to rotate, which effectively improves the stability of the guide tube 7 when moving. The lower end of the slide plate 12 is fixedly connected to two limit rods 13, and the upper end of the support frame 2 is chiseled with two slide grooves 14. The lower end of the limit rod 13 is slidably connected to the slide groove 14, and the limit rod 13 can slide in the slide groove 14, thereby limiting the guide tube 7.

[0027] When in use, the longitudinal position of the guide tube 7 can be adjusted by pulling the guide tube 7. During the movement of the guide tube 7, the fixed plate 6 limits the outer surface of the guide tube 7, and the fixed ring 10 moves with the movement of the guide tube 7, thereby driving the support plate 11 and the slide plate 12 to move. The limiting rod 13 moves in the slide groove 14, thereby limiting the curved side of the guide tube 7. Under high temperature, the fixed plate 6 and the support plate 11 support the guide tube 7, so that the guide tube 7 is not easily deformed and twisted, thereby effectively avoiding damage to the internal thermocouple wire 9 of the guide tube 7 due to deformation, and effectively avoiding friction with the roller, thereby effectively improving the stability of the thermocouple temperature measuring component during temperature measurement.

[0028] The second implementation method:

[0029] Based on the first embodiment, this embodiment adds a support ring 8 and a scale line 15, and the rest of the parts remain the same as the first embodiment.

[0030] Figure 7It is shown that a support ring 8 is fixedly embedded in the front end of the guide tube 7, and the support ring 8 is movably sleeved on the outer surface of the thermocouple wire 9. The support ring 8 can limit the thermocouple wire 9, and the outer surface of the guide tube 7 is printed with scale lines 15.

[0031] During use, the support ring 8 can limit and fix the thermocouple wire 9, thereby effectively preventing the thermocouple wire 9 from being displaced when the guide tube 7 is pulled. At the same time, the moving distance of the guide tube 7 can be observed through the scale line 15, which is convenient for the staff to use.

[0032] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
