Description
Technical Field
[0001] The invention belongs to the technical field of glass edge grinding, and in particular relates to a glass edge grinding device with an anti-scratch function. Background Art
[0002] In the process of glass processing, it is usually necessary to slice the glass first and then grind its edges. Glass slicing refers to cutting the glass into square, round or other required shapes using a slicing device; glass grinding refers to grinding the glass edges to a smooth finish using an edge grinding device. In the glass edge grinding process, the glass needs to be clamped by two parallel rows of rollers, and the glass is transported to the grinding area in a horizontal state through two sets of rollers. In the grinding area, two sets of horizontally symmetrical grinding wheels are used to grind the edges of both sides of the glass at the same time. The grinding wheel is made of high-hardness materials such as diamond or silicon carbide, and is driven by a motor to rotate at high speed to achieve efficient edge grinding operations.
[0003] However, this grinding method has serious problems: during the high-speed rotation of the grinding wheel, due to the intense friction with the edge of the glass, a large amount of glass fragments and debris will be generated. These glass fragments and debris will fly around with the high-speed rotation of the grinding wheel. Some larger glass fragments will fall on the surface of the glass. When the rollers continue to convey the glass, the larger fragments on the surface of the glass will be rolled by the rollers, causing scratches or damage to the surface of the glass. Such scratches not only affect the aesthetics of the glass, but may also reduce the mechanical strength and service life of the glass. Lightweight glass fragments will float in the air, causing pollution to the environment. If the glass fragments are inhaled by the human body, it will cause irreversible damage to the human body. Summary of the invention

DETAILED DESCRIPTION
[0025] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.
[0026] Embodiment 1:
[0027] See also Figures 1 to 3 The present invention provides a glass edge grinding device with an anti-scratch function, comprising a water tank 1 and a moving mechanism. The water tank 1 is an upper open structure, and water is stored in the water tank 1. A lifting mechanism is arranged above the water tank 1, and the lifting mechanism is connected to a glass clamping mechanism. After the glass clamping mechanism clamps the glass 10, the lifting mechanism can drive the glass 10 to lift vertically, and lower the lower side of the glass 10 below the water surface. The moving mechanism is horizontally arranged in the water tank 1, and the moving mechanism is connected to a moving sleeve 16. The moving mechanism can drive the moving sleeve 16 to move horizontally, and the moving sleeve 16 slides vertically. A slider 17 is provided, and a support rod 18 is provided on the upper surface of the slider 17, so that the support rod 18 can only slide in the movable sleeve 16 but cannot rotate in the movable sleeve 16. The upper side of the support rod 18 passes through the top of the movable sleeve 16 and is fixedly connected to a buoyancy box 20. A limiter is provided on the inner wall of the upper end of the movable sleeve 16 to prevent the slider 17 from sliding out of the upper end of the movable sleeve 16. A grinding assembly is provided on the buoyancy box 20, and the grinding assembly can grind the underwater edge of the glass 10. The moving mechanism can drive the grinding assembly to move horizontally along the lower edge of the glass 10 underwater.
[0028] The present invention can be used for polishing square glass 10, round glass 10 or round glass 10 with lace, and has a wide range of application effects;
[0029] When grinding the square glass 10, after the glass clamping mechanism is used to clamp the middle of the glass 10, the lifting mechanism is used to lower the glass 10 into the water so that the grinding assembly is against the lower edge of the glass 10. In this process, the glass 10 will drive the slider 17 to move downward in the moving sleeve 16 through the grinding assembly, the floating box 20 and the support rod 18; the moving mechanism is controlled to drive the grinding assembly to move horizontally, so that the lower edge of the glass 10 can be continuously ground. In the mobile grinding process, after the lower edge of the square glass 10 is lowered into the water, there will be mechanical errors in the glass clamping mechanism, the lifting mechanism and other components, which will cause the lower edge of the glass to tilt after the glass is positioned and clamped. The buoyancy of the buoyancy box 20 can provide a constant squeezing force to the edge of the glass 10, so that the grinding assembly can be kept in contact with the edge of the glass 10, which can effectively avoid the unevenness or cracking of the polished edge caused by the sudden change of squeezing force due to the height difference of the lower edge of the glass during the mobile grinding process. In addition, the grinding is performed underwater, which has a comprehensive and sufficient cooling effect. In the water, the water pressure is used to press the glass 10 from both sides and the lower edge of the glass 10, which is equivalent to multi-faceted clamping of the glass 10 where it is being polished, which can effectively alleviate the cracking of the glass 10 during the grinding process. In addition, grinding in water and using the resistance of water can greatly suppress the flying of glass slag and debris, so that the slag and debris are retained in the water after grinding.

After starting the grinding assembly, the glass clamping mechanism is used to drive the glass 10 to rotate, and the buoyancy is used to provide a constant squeezing force. The moving sleeve 16 and the support rod 18 cooperate to provide a suitable feed amount, so that the grinding assembly can follow the ups and downs of the edge of the glass 10 to continuously grind the entire edge of the glass 10, with high grinding efficiency and good grinding effect.
