Description

Technical Field

[0001] The utility model relates to the technical field of glass manufacturing, in particular to a novel short roller top wire measuring and adjusting device. Background Art

[0002] During the overflow down-draw liquid crystal glass manufacturing process, the glass plate is formed by overflow bricks and is pulled down into shape by traction mechanisms such as edge drawing machines and short rollers. During the manufacturing process, the short rollers are required to be in a stable state such as consistent clamping force, no misaligned virtual clamping, and centered clamping when running at high speed to ensure the stability of the edge process of the glass plate during the down-drawing process, thereby reducing the occurrence of defects and ensuring the normal progress of production.

[0003] In the prior art, when producing glass plates, two short rollers arranged opposite to each other are used to clamp the glass plates and pull them down. During this process, the short rollers will gradually wear out due to long-term rotation. At this time, the clamping force of the short rollers on the glass plates will gradually decrease. In order to ensure that the clamping force of the short rollers on the glass plates is stable, the operator needs to adjust the spacing between the two short rollers according to the degree of wear of the short rollers. During adjustment, the short rollers are driven to move by tightening the hexagonal screws. This method has large measurement errors and low adjustment accuracy. Utility Model Content

[0034] Working principle:

[0035] The T-shaped slider 3 can be moved by the micrometer distance adjustment assembly 4. The two micrometer distance adjustment assemblies 4 can be used together to adjust the distance between the two T-shaped sliders 3, and then the distance between the two short rollers 10 can be adjusted. When the surface of the short roller is worn and the clamping force is insufficient, the distance between the two short rollers is reduced so that the two short rollers are more closely attached to the corresponding side of the glass substrate, thereby enhancing the friction between the two short rollers and the glass substrate, and the short rollers clamp the glass substrate in the center, and the clamping force is re-enhanced;

[0036] During the distance adjustment process, the sliding distance of the T-shaped slider 3 can be measured by the laser rangefinder 6. At the same time, the surfaces of the fixed sleeve 45 and the differential cylinder 43 of the micrometer distance adjustment assembly 4 are both provided with scales 47. The two can be used together to accurately adjust the length of the top screw extension. The use of the micrometer can ensure that the extension length of the top screw is accurate to 0.01mm, thereby ensuring that the spacing between the two short rollers can be accurately adjusted to reduce operating errors. The more accurate the adjustment of the spacing between the two short rollers, the better the clamping force, and the higher the quality of the glass substrate in the annealing and pulling process production. After the top screw length is determined, the top screw can be fixed by the use of the locking tongue 46, the locking bolt 48, etc. After the top screw is fixed, the slider cannot move, and the spacing between the two short rollers is locked.
