Description

Technical Field

[0001] This invention relates to the field of glass manufacturing processes, and in particular to an anvil device for use in a liquid crystal glass substrate slitting machine. Background Technology

[0002] Longitudinal cutting is a crucial step in the overflow-draw process for manufacturing flat glass. This process involves longitudinally cutting and breaking the glass sheet before transporting it to subsequent finishing stages. Cutting quality is paramount in the longitudinal cutting process. Poor cutting can lead to broken or broken sheets, making proper cutting essential for continuous and stable production.

[0003] The cutting board strips in the existing technology are circular. Since the contact between the circular cutting board strip and the glass surface is a straight line, the cutter cuts from top to bottom. This straight line needs to be perpendicular to a certain extent. Otherwise, there is no support on the other side of the cutter, which will cause the cutting depth to not reach the expected result. Summary of the Invention

[0004] The present invention aims to provide an anvil device for use in a liquid crystal glass substrate longitudinal slicing machine with high cutting quality.

[0005] Technical solution: An anvil device for a liquid crystal glass substrate slitting machine includes an A-side anvil strip assembly, a B-side anvil strip assembly, and a suction cup device for clamping the glass. The A-side anvil strip assembly is provided in two sets, with the cutter vertically arranged between the two sets of A-side anvil strip assemblies. The B-side anvil strip assembly is located on the other side of the glass, with the side of the B-side anvil strip assembly away from the glass edge extending beyond the cut surface of the cutter by a distance L2. The suction cup device is aligned with the A-side anvil strip assembly away from the cutter.

[0006] The A-side cutting board strip assembly includes a first A-side cutting board strip, a second A-side cutting board strip, a cutting board strip mounting groove, a mounting bracket one, and a mounting bracket two. The first A-side cutting board strip and the second A-side cutting board strip are installed on the cutting board strip mounting groove. The cutting board strip mounting groove is installed on the slitting machine body through the mounting bracket one and the mounting bracket two. The cutting board strip on the side of the two A-side cutting board strip assemblies away from the cutter is slidably installed on the slitting machine body.

[0007] The distance from the center of the cutter to the center of the A-side anvil assembly, which is farther away from the B-side anvil assembly, is L1, and the distance from the center of the cutter to the center of the A-side anvil assembly, which is closer to the B-side anvil assembly, is L3.

[0008] The value of L1 ranges from 80mm to 140mm.

[0009] The feature is that the value of L3 is in the range of 25mm-35mm.

[0010] The B-side cutting board strip assembly includes two sets of B-side cutting board strips, each including a left B-side cutting board strip, a right B-side cutting board strip, a B-side cutting board strip mounting groove, an adjusting block, and a top block. The left and right B-side cutting board strips are installed on the B-side cutting board strip mounting groove, which is pressed against the slitting machine body by the adjusting block. The adjusting block and the top block are used to adjust the installation position of the B-side cutting board strip mounting groove on the slitting machine body.

[0011] The feature is that the distance from the center of the cutter to the left side of the left anvil strip on the B side is L2, and the right anvil strip on the B side of the other set of B side anvil strips is aligned with the second A side anvil strip that is away from the cutter.

[0012] The feature is that the value of L2 ranges from 1mm to 3mm.

[0013] The feature is that the suction cup device is aligned with the center of the A-side anvil strip assembly away from the cutter, and at least three sets of suction cup devices are provided along the cutting direction of the cutter.

[0014] The top block has a breakage angle of 15° with respect to the horizontal direction along the direction of the glass bait.

[0015] Beneficial effects: The flat anvil strip device of this invention has a surface-to-surface contact between the flat anvil strip and the glass surface, and the cutting blade is always supported by a support point, ensuring the cutting depth and facilitating the breaking action. Secondly, the distances L1, L2, and L3 between the support point and the cutting point in the flat anvil strip of this invention are adjustable, making it suitable for cutting glass of various sizes. After cutting, the breaking mechanism breaks the glass. Because the circular anvil strip is curved, the glass can be smoothly broken around the center of the breaking mechanism. The flat anvil strip is at a vertical angle, which is not conducive to the breaking action. By adjusting the size of L1, the tilted breaking angle can be set to find the optimal distance between the blade tip and the edge of the flat anvil strip without affecting the breaking action. At the same time, the L2 and L3 parameter settings also ensure that the glass is clamped stably, eliminating the risk of shaking. Attached Figure Description

The A-side cutting board strip assembly 1 includes a first A-side cutting board strip 11, a second A-side cutting board strip 12, a cutting board strip mounting groove 13, a mounting bracket one 14, and a mounting bracket two 15. The first A-side cutting board strip 11 and the second A-side cutting board strip 12 are mounted on the cutting board strip mounting groove 13. The cutting board strip mounting groove 13 is mounted on the longitudinal slicing machine body through the mounting bracket one 14 and the mounting bracket two 15. The cutting board strip on the side of the two A-side cutting board strip assemblies 1 that is away from the cutter 5 is slidably mounted on the longitudinal slicing machine body. The distance from the center of the cutter 5 to the center of the A-side cutting board strip assembly 1 that is away from the B-side cutting board strip assembly 2 is L1, and the distance from the center of the cutter 5 to the center of the A-side cutting board strip assembly 1 that is close to the B-side cutting board strip assembly 2 is L3. In this embodiment, the value range of L1 is 80mm-140mm, and the value range of L3 is 25mm-35mm.

[0021] The B-side cutting board strip assembly 2 includes two sets of B-side cutting board strips 21. Each B-side cutting board strip 21 includes a left B-side cutting board strip 211, a right B-side cutting board strip 212, a B-side cutting board strip mounting groove 213, an adjusting block 214, and a top block 215. The left B-side cutting board strip 211 and the right B-side cutting board strip 212 are mounted on the B-side cutting board strip mounting groove 213. The B-side cutting board strip mounting groove 213 is pressed against the slitting machine body by the adjusting block 214. At the same time, the adjusting block 214 and the top block 215 are used to adjust the mounting position of the B-side cutting board strip mounting groove 213 on the slitting machine body. The distance from the center of the cutter 5 to the left side of the left B-side cutting board strip 211 is L2. The right B-side cutting board strip 212 of the other set of B-side cutting board strips 21 is aligned with the second A-side cutting board strip 12 that is away from the cutter 5. In this embodiment, the value of L2 ranges from 1mm to 3mm.

[0022] The suction cup device 3 is aligned with the center of the A-side anvil strip assembly 1, which is away from the cutter 5. At least three sets of suction cup devices 3 are provided along the cutting direction of the cutter 5. The top block 215 has a 15° breakage angle with the horizontal direction along the direction of the bait on the glass 4.

[0023] Workflow: In the specific implementation process, the glass 4 is clamped by the A-side cutting board strip assembly 1, the B-side cutting board strip assembly 2 and the suction cup device 3. The position of the glass 4 is adjusted according to the required size. The glass 4 is cut by the cutter 5. The cutter cuts from top to bottom, and this straight line needs to ensure a certain degree of perpendicularity. After the cutter completes the cut, the longitudinal cutting machine body grabs the left side of the glass 4 by the suction cup device and completes the breaking action.
