Description

Technical Field

[0001] This application relates to the field of glass production technology, and in particular to a speed measuring device for glass production. Background Technology

[0002] In the cold-end stage of float glass production, accurate measurement of the glass sheet running speed is crucial. The speed signal is a key parameter for controlling the synchronous operation of equipment such as cutting machines and stacking machines, directly determining the accuracy of the cutting length and the neatness of the stacking.

[0003] Currently, contact-type speed measuring wheels are widely used in cold-end production lines for speed measurement. Their basic working principle is as follows: the speed measuring wheel rotates under the influence of a glass plate, and an encoder mounted on the wheel axle converts the rotational angular velocity into electrical pulse signals, thereby calculating the real-time linear velocity of the glass plate.

[0004] Existing speed measuring wheel structures generally suffer from the following problems in practical applications: 1. Slippage: This is the most significant factor affecting measurement accuracy. Due to the smooth surface of the glass plate, and the potential presence of moisture, dust, or tiny glass shards, the friction between the speed measuring wheel and the glass plate surface is insufficient, causing relative slippage and resulting in a speed measurement value lower than the actual value.

[0005] 2. Jumping and Vibration: Insufficient rigidity of the speed measuring wheel mounting structure or excessive bearing clearance will cause jumping and vibration during high-speed operation. This not only affects the stability of the encoder signal, but may also cause scratches on the glass surface.

[0006] 3. Poor adaptability: The contact pressure and friction coefficient need to be adjusted for glass plates of different thicknesses and surface conditions. Traditional structures are inconvenient to adjust and it is difficult to maintain the best measurement conditions at all times.

[0007] 4. Inconvenient maintenance: Replacing worn speed measuring wheels or encoders often requires disassembling multiple parts, which is cumbersome and affects production efficiency. Utility Model Content

A pair of bolts are provided on the left and right sides of the vertical shaft. One end of each bolt passes through the connecting frame and abuts against the frame. A first nut and a second nut are respectively fitted on the bolts on the front and rear sides of the connecting frame.

A cylinder is hinged to the connecting frame above the first swing frame, and one end of the cylinder is hinged to the first swing frame. The first axle wheel is rotatably mounted at the bottom of the first swing frame. A second swing frame is hinged to the first swing frame above the second axle wheel. The second axle wheel is rotatably connected to the second swing frame and is tangent to the first axle wheel. An encoder is mounted on the second axle wheel.

[0014] Compared with the prior art, the advantages of this utility model are: Beneficial benefits: The position of the first axle wheel is adjusted by a cylinder. On the one hand, this effectively controls the first axle wheel to always be in contact with the glass with a certain pressure, increasing friction and preventing jumping.

At the same time, a pair of bolts, in cooperation with the first nut and the second nut, adjust the swing position of the first axle wheel, thereby ensuring that the rotation direction of the axle wheel is the same as the glass conveying direction during installation, so as to better measure.
