[0026] A mounting base 1 having vertically arranged through holes;

[0027] A stirring shaft 2, the stirring shaft 2 passes through the through hole and is rotatably connected to the mounting seat 1, and a stirring blade is provided on the stirring shaft 2;

[0028] A driving motor 3, which is connected to the stirring shaft 2 via a belt and can drive the stirring shaft 2 to rotate;

[0029] An elastic clamping assembly 4, the elastic clamping assembly 4 contacts the mounting seat 1;

[0030] A driving cylinder 5, which is connected to the elastic clamping assembly 4 and can drive the elastic clamping assembly 4 to clamp the mounting seat 1;

[0031] A data collector 6, which is used to instantly collect raw data for determining whether the radial amplitude of the stirring shaft 2 exceeds a preset value;

[0032] The controller is communicatively connected to the data acquisition device 6, and the controller controls the driving cylinder 5. When the controller determines through the real-time raw data that the radial amplitude of the stirring shaft 2 exceeds the preset value, the controller controls the driving cylinder 5 to increase the clamping force of the elastic clamping assembly 4 on the mounting seat 1 to reduce the radial amplitude of the stirring shaft 2 to below the preset value.

[0033] The stirring shaft 2 is provided with stirring blades for stirring the flowing glass liquid. The driving motor 3 is connected to the stirring shaft 2 through a belt to provide power for the rotation of the stirring shaft 2.

[0034] The elastic clamping assembly 4 includes three support members, the output end of the driving cylinder 5 is fixed to the end of the support member, and the three support members are arranged in a circular array outside the mounting base 1. The support members include a cylindrical member 7, a spring 9 and a top plate 8. The three top plates 8 are directly in contact with the outer wall of the mounting base 1.

[0035] The support member has a groove body inside, and the cylindrical member 7 is fixed on the bottom wall of the groove body. The cylindrical member 7 has a blind hole inside. A guide rod coaxial with the cylindrical member 7 is movably inserted inside the blind hole. The end of the guide rod is fixed to the top plate 8. The end of the spring 9 is fixed to the outside of the cylindrical member 7 and applies pressure to the mounting seat 1 through the top plate 8.

[0036] The cylindrical member 7 is fixed on the bottom wall of the inner groove of the support member, and has a blind hole inside. A guide rod coaxial with the cylindrical member 7 is movably inserted inside the blind hole, and the end of the guide rod is fixed to the top plate 8. The function of the guide rod is to ensure that the top plate 8 maintains a stable direction during movement to prevent deviation or shaking. The end of the spring 9 is fixed to the outside of the cylindrical member 7, and applies pressure to the mounting seat 1 through the top plate 8.

[0037] The data collector 6 specifically includes:

[0038] An emitting end, wherein the light emitted by the emitting end is perpendicular to the first radial direction 11 of the stirring shaft, and the shortest distance between the light and a first outer wall line on the outer wall of the stirring shaft 2 that intersects the first radial direction 11 perpendicularly is equal to a preset value;

[0040] The transmitter and receiver use high-precision photoelectric sensors that can quickly and accurately detect the on and off status of light.

[0041] “Judging whether the radial amplitude of the stirring shaft 2 exceeds the preset value” is specifically:

[0042] When the receiving end 10 changes from being unable / able to receive the light emitted by the transmitting end to being able / unable to receive the light emitted by the transmitting end, it is determined that the radial amplitude of the stirring shaft 2 exceeds the preset value.

[0043] The controller is connected to the data collector 6 and is controlled to the drive cylinder 5.

[0044] In order to adapt to different working conditions and the amplitude variation range of the stirring shaft 2, the stirring device 12 also includes an adjustment device for movably mounting the data collector 6. The adjustment device 12 uses two electric telescopic rods, and the transmitting end and the receiving end are respectively fixedly mounted on the ends of the output shafts of the two electric telescopic rods. By controlling the extension and contraction of the electric telescopic rods, the shortest distance between the light and the first outer wall line on the outer side wall of the stirring shaft 2 that intersects the first radial direction 11 perpendicularly can be adjusted along the first radial direction 11, thereby achieving adjustment of different preset values.
