Description

Technical Field

[0001] The utility model relates to the field of glass production equipment, in particular to an online edge breaking device for high-strength glass. Background Art

[0002] Float glass is a process in which qualified batch materials are heated and melted at high temperature to form a transparent, pure, uniform and suitable glass liquid for forming. The glass liquid flows into the tin bath through the flow channel and floats on the surface of the relatively dense tin bath. Under the surface tension of its own gravity, the pulling force of the edge drawing machine and the transition roller table, the glass liquid is spread, flattened, polished, and thinned (thickened) on the tin bath surface to form a glass substrate with smooth upper and lower surfaces. However, when it is cooled to 600-620℃, it is pulled onto the transition roller table under the traction of the transition roller table outside the tail of the tin bath and the annealing furnace drive roller connected to it, and then conveyed to the annealing furnace. The annealing furnace slowly cools the tin bath-formed glass from 600℃ to 70℃, eliminating or weakening the residual stress and optical inhomogeneity in the glass products, and improving the internal structure of the glass. The annealed glass is transported to the cross-cutting area and cut into various sizes according to the customer's requirements for the glass size. As an important link in the subsequent smooth board placement of glass manufacturing, the operation of its equipment is also crucial.

[0003] At present, when producing high-strength thick plates with a thickness of 10mm and 12mm, when the qualified plate width of 3660mm is optimized to be cut into a plate width of 3050mm or a plate width of 3300mm, there are 610mm and 360mm extra on the original edges. Due to the wider cutting edges and the greater stress on the edges of thicker plates, the existing edge bending machines use single-wheel bending for edge bending, which results in uneven force and cracked edges, multiple missing corners, and broken edges. When optimizing and cutting into plates with a width of 3050mm or a plate width of 3300mm, the plates are directly broken at the longitudinal breaking position. Due to the insufficient longitudinal force of the single wheel, the longitudinal top wheel cannot be assisted to push the cutting line open, so the glass edge cannot be broken.

[0004] Therefore, it is necessary to design a bending device that can be adapted to the breaking of high-strength glass. Utility Model Content

[0039] The working principle of this high-strength glass online edge bending device is as follows:

[0040] When producing 10mm / 12mm / 15mm thick float glass, when the quality detector detects level 7-8 defects, the production is optimized and cut into 3050mm or 3300mm wide glass. The glass plate passes through the edge cleaning area, removes the two glass edges with tooth marks, and forms a glass plate with a net width of 3660mm and enters the edge bending area;

[0041] The personnel on both sides operate the shaking width adjustment wheel 411 at the same time to make the support frame 3 move slowly toward the edge of the glass plate as a whole, until the support frame 3 moves to the position where the pressure wheel group 34 is 20-100mm away from the edge of the glass plate, and then stop the operation; the personnel on both sides then slowly shake down the height hand wheel, adjust the height of the support frame 3 as a whole, and lower it until the lower end of the pressure wheel group 34 is 5mm above the glass plate, and then stop the operation;

[0042] At this time, the pressure wheel groups 34 stay at the left and right sides of the glass plate respectively, and the top wheel group 5 moves to the bottom of the cutting line pre-formed on the glass plate according to the measurement of the cross-cutting system. The top wheel group 5 rises to make the pressure wheel groups 34 on both sides compact the glass edges, thereby separating the glass plates along the cutting line, thus completing the optimized cutting of 3050mm or 3300mm.

[0043] The above is only a specific implementation of the present utility model, but the design concept of the present utility model is not limited to this. Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
