Glass cutting device

Abstract

The invention discloses a glass cutting device, which includes a cutter knife body, a dust sucking device arranged in parallel therewith, and a bracket which connects the cutter knife body to the dust sucking device. The cutter knife body, the bracket and the dust sucking device are arranged in a cutting moving direction successively. The cutter knife body comprises: a cutting frame connected to one end of the bracket and a cutter knife wheel connected to the bottom of the cutting frame through a wheel pin. The dust sucking device includes a support board which is connected to the other end of the bracket, and a first dust sucking head which is disposed on the bottom surface of the support board and towards the cutter knife wheel. The first dust sucking head is connected to an external electric exhaust fan having a dust collection box through a dust suction soft pipe, wherein the electric exhaust fan is used for providing vacuum sucking force. The glass cutting device is compact in structure, is convenient to detach, is easy to produce, is safe and reliable and is strong in practicability. The glass cutting device can suck glass chips generated from the cutter knife wheel quickly and prevent the glass chips from being attached to surface of glass, thereby reducing pollution, and further can reduce the environment pollution in a dustless workshop due to the glass chips.

Description

technical field [0001] The invention relates to a cutting device, in particular to a glass cutting device. Background technique [0002] At present, the demand for glass in the market is increasing day by day, and there are more and more types and sizes of widely used glass. This puts forward higher requirements for the performance and dimensional accuracy of the glass. Small size, high strength and rigidity, uniform material, and require high efficiency and speed in glass cutting and production. [0003] Usually, in glass cutting, a roller made of diamond sintered body or superhard alloy with a diameter of several millimeters and a ridgeline on its circumference moves while applying a certain pressure on the glass surface; It moves while penetrating into the glass surface, and moves while forming horizontal scratches with a width of several micrometers in depth and width, and at the same time, forms tens of μm perpendicular to the glass surface inside the glass directly be...

AI Technical Summary

Problems solved by technology

[0004] Among them, vertical cracks are a necessary condition for the subsequent glass separation process. However, the horizontal scratches generated during the scribing process will not only affect the edge quality of the glass after separation, that is, the fracture surface is not smooth enough after the glass is broken, but also excess glass debris will appear.

Glass debris will adhere to the glass surface and cause scratches or pollution to the glass surface in the subsequent process, thus directly affecting the quality of the product; at the same time, the raised glass debris will also pollute the environment of the clean workshop
