Description

Technical Field

[0001] The invention relates to the technical field of roller speed measurement, in particular to an ultra-thin electronic glass roller speed measurement bracket. Background Art

[0002] At present, the speed control of ultra-thin electronic glass production lines mainly depends on the measurement and adjustment of roller speed. The market demand for ultra-thin electronic glass is gradually shifting to high-end products, such as high-performance touch screens and flexible displays. These products have higher requirements for the physical properties of glass, such as thickness, flatness and transparency. With the intensification of market competition, manufacturers must continuously improve product quality and production efficiency to maintain their competitive advantage. This requires the production line to be more accurate and stable in speed control. The apparent quality requirements of high-end ultra-thin electronic glass products are getting higher and higher, and any tiny defects may affect the final performance of the product. Therefore, the speed control of the production line must be able to ensure the stability and consistency of the glass during the forming, cooling and transmission process. Accurate control of the production line speed is the key to ensuring product quality and production efficiency. The error in speed control will directly affect important parameters such as glass thickness uniformity, surface flatness and stress distribution. In order to ensure the accuracy of speed control, the frequency of daily measurement of roller speed has gradually increased. Most measurements are online measurements, that is, real-time monitoring and adjustment of roller speed during the production process.

[0003] However, existing methods usually adopt the form of random sampling for measurement, and the measuring equipment uses photoelectric sensors, which leads to the fact that the measuring equipment and methods are still insufficient in accuracy, including: 1. In high-speed production lines, small speed changes may not be accurately captured; 2. High-frequency, high-precision real-time measurement cannot be achieved; 3. The processing and feedback speed of measurement data is slow, and the production line speed cannot be adjusted in time; 4. In the existing speed control process, there is a lot of manual intervention, which is prone to operational errors, affecting the accuracy of measurement and adjustment. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing rotation speed detection of the support roller by using a photoelectric sensor has low accuracy, low frequency and slow data processing speed.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an ultra-thin electronic glass roller speed measuring bracket, including a bracket connected to a mounting plate for fixing a support roller by bolts, an encoder is fixed on the bracket, the detection shaft of the encoder is connected to the connecting plate through a coupling, the connecting plate is clamped on the end of the support roller, the coupling signal is connected to a linear speed meter, and the driving control system and alarm of the support roller are connected through the linear speed meter.

[0026] Before locking the bracket 1, first put the connecting disc 4 on the end of the supporting roller 9, then lock the connecting disc 4 on the end of the supporting roller 9 through the locking block 7, and then lock the coupling 3 on the connecting shaft 12 of the connecting disc 4.

[0027] By utilizing the screw holes on the mounting plate 10 for rotatably supporting the support roller 9 in the roller table, the width of the bracket 1 is designed according to the relative screw hole spacing, so that the two end holes of the bracket 1 are connected to the two screw holes by bolts, and then the bracket 1 is locked on the mounting plate 10.

The locking block 7 is provided with a strip hole 11 for the locking bolt 8 to pass through. The length direction of the strip hole 11 faces the axis of the connecting plate 4. The end wall of the locking block 7 is provided with an adapting protrusion with a right-angle trapezoidal cross section. The edge of the receiving hole is provided with a chamfer that matches the inclined surface of the adapting protrusion.

[0034] A speed measuring method for an ultra-thin electronic glass roller speed measuring bracket comprises the following steps: Step 1: Fix the bracket 1 to the mounting plate 10 by bolts, put the connecting plate 4 on the end of the supporting roller 9, screw in the positioning bolt 6, and keep the positioning bolt 6 extending to the same length, adjust the connecting tube 4 to be coaxial with the supporting roller 9, and then tighten the locking bolt 8 to make the locking block 7 inwardly inserted between the connecting plate 4 and the supporting roller 9, and lock the connecting plate 4 on the supporting roller 9 with the locking bolt 8; Step 2: The linear speed of the support roller 9 is detected by the encoder 2, and the linear speed information is transmitted to the linear speed meter, which then compares the detected linear speed with the set upper and lower thresholds of the linear speed. When the detected linear speed exceeds the upper threshold or is lower than the lower threshold, the linear speed meter transmits a signal to the alarm, and the alarm sounds an alarm; Step 3: Linear speed: All the detected linear speed information of the support roller 9 is sent to the drive control system of the support roller 9, and the linear speed information is recorded and displayed graphically by the drive control system, such as Figure 4 As shown, the driving adjustment of the rotation of the support roller 9 can be performed subsequently according to the corresponding fluctuation conditions.
