Description

Technical Field

[0001] This utility model relates to the field of glass technology, and more specifically, to a single-round-edge grinding machine for glass. Background Technology

[0002] Glass is a hard, brittle, transparent amorphous solid material widely used in many fields such as construction, automobiles, electronics, medical, and daily necessities. It is an indispensable basic material in modern industry and life. Glass processing requires the use of a single-round-edge glass grinding machine, which is a key piece of equipment in the field of glass deep processing and is widely used in furniture glass, architectural decorative glass, and other scenarios.

[0003] For example, CN213730902U discloses a circular glass edging machine that is easy to position, belonging to the technical field of glass processing equipment. This circular glass edging machine includes a base plate, with a mounting frame fixedly connected to the upper surface of the base plate. A limiting rotating block is fixedly connected to the inner wall of the mounting frame, and a limiting fixing block is fixedly connected to the outer surface of the limiting rotating block. A screw is movably connected to the inner wall of the limiting rotating block. When using the edging machine to grind circular glass, a servo motor is started, which drives the screw to rotate forward (reverse), thereby controlling the moving block mounted on the screw to move forward (backward). This causes the edging head mounted on the mounting rod on the moving block to move forward (backward), facilitating the grinding of circular glass. This eliminates the need for manual grinding of circular glass and allows for automatic control of the edging machine, reducing the labor intensity of employees, making the glass edge smoother, and improving the grinding efficiency of the glass.

[0004] For example, publication number CN222680454U discloses a rounded corner grinding machine for glass processing, relating to the field of deep hole processing technology. It includes a worktable and a rounded corner positioning mechanism mounted on the worktable. A slide block is slidably connected to the worktable via a guide rail, and a support rod is slidably connected to the slide block. One end of the support rod is equipped with a rotating mechanism. A grinding mechanism and a spraying mechanism are fixedly mounted on the rotating mechanism, and the rotation center of the rotating mechanism is concentric with the rounded corner of the glass. This invention uses the rotating mechanism to drive the grinding mechanism to perform rounded corner processing and edge grinding on the edges of a glass plate fixedly adsorbed on a vacuum suction cup. The rotation center of the rotating mechanism is concentric with the rounded corner of the glass, achieving the effect of rounded corner grinding on the glass, greatly improving grinding efficiency. Simultaneously, the radius of the rounded corner can be adjusted by adjusting the feed amount of the telescopic cylinder according to requirements. The device has low cost and strong applicability.

[0005] While the first comparative example eliminates the need for manual grinding of round glass using a grinding machine, allowing for automated grinding and reducing labor intensity, resulting in smoother glass edges and improved grinding efficiency, the second comparative example allows for adjustment of the radius of the rounded corners by adjusting the feed amount of the telescopic cylinder. This device is low-cost and highly adaptable. However, the single-edge grinding machine only uses a bottom suction cup to limit and fix the glass, relying on the suction force to position it. During the grinding process, the glass is prone to longitudinal displacement (perpendicular to the grinding direction) due to friction between the grinding wheel and the glass, as well as vibrations from equipment operation. Lacking effective constraints on the sides and top of the glass, the suction force of the suction cup is insufficient to counteract the longitudinal force, causing changes in the relative position of the glass edge and the grinding wheel.

[0006] Therefore, we have made improvements to this and proposed a single-round-edge grinding machine for glass. Utility Model Content

[0007] The purpose of this invention is to address the fact that existing glass single-edge grinding machines only use bottom suction cups to limit and fix the glass, relying on the suction force of the suction cups to achieve glass positioning. During the grinding process, the glass is easily offset along the longitudinal direction (perpendicular to the grinding direction) due to the friction generated by the contact between the grinding wheel and the glass, the vibration of the equipment, and other factors. Due to the lack of effective constraints on the sides and top of the glass, the suction force of the suction cups is difficult to counteract the longitudinal force, resulting in changes in the relative position of the glass edge and the grinding wheel.

[0040] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7The first limiting component 7 includes a support plate 701, which is fixedly installed at the bottom of the inner cavity of the outer shell 4. An electric telescopic rod 702 is fixedly installed on the left side of the support plate 701. A connecting block 703 is fixedly installed on the left side of the electric telescopic rod 702. A toothed plate 704 is fixedly installed on the rear side of the connecting block 703. A rotating gear 705 meshes with the rear side of the toothed plate 704. A rotating rod 706 is fixedly installed in the inner cavity of the rotating gear 705. The rotating rod 706 is movably connected to the outer shell 4 on the side near the outer shell 4. The inner cavity of the rotating rod 706 is movably connected to the surface of the output end of the motor 3. An adjusting plate 707 is fixedly installed on the top of the rotating rod 706. Three guide grooves 708 are opened in the inner cavity of the adjusting plate 707. A movable rod 709 is movably connected to the inner cavity of the guide grooves 708. The top of the movable rod 709 passes through the limiting groove 5 to the top of the outer shell 4 and is fixedly installed with a buffer member 710. The bottom of the buffer member 710 is in contact with the top of the outer shell 4. A spring 711 is fixedly installed on one side of the inner cavity of the buffer 710. A baffle 712 is fixedly installed on one side of the spring 711. A fixing block 713 is fixedly installed on one side of the baffle 712. One side of the fixing block 713 extends through to one side of the buffer 710 and is fixedly installed with a clamping member 714. One side of the clamping member 714 is movably connected to a limiting roller 719 via a rotating shaft. A limiting plate 715 is sleeved on the surface of the electric telescopic rod 702. The side of the limiting plate 715 near the support plate 701 is fixedly connected to the support plate 701. A sliding block 716 is fixedly installed at the bottom of the toothed plate 704. A sliding rod 717 is slidably connected to the inner cavity of the sliding block 716. The side of the sliding rod 717 near the support plate 701 is fixedly connected to the support plate 701. Limiting blocks 718 are fixedly installed at both the top and bottom of the baffle 712. The limiting blocks 718 are slidably connected to the inner cavity of the buffer 710. The device uses base 1 as its support foundation, with legs 2 enhancing overall stability. Motor 3, as the power source, is fixed to one side of base 1, and its output shaft is connected to the rotating shaft of suction cup 6 via a coupling. When motor 3 starts, the power drives suction cup 6 to rotate uniformly around its own axis via the coupling. After the glass is placed on the surface of suction cup 6, suction cup 6 generates negative pressure to adhere to the bottom of the glass, causing the glass to rotate synchronously with suction cup 6. The electric telescopic rod 702 of the first limiting component 7 is installed inside the outer casing 4. After activation, it pushes the toothed plate 704 to move laterally along the sliding rod 717. The meshing transmission with the rotating gear 705 drives the adjusting plate 707 to rotate. The guide groove 708 of the adjusting plate 707 drives the movable rod 709 to extend synchronously towards the glass along the limiting groove 5 of the outer shell 4, so that the clamping member 714 and the limiting roller 719 at the end of the buffer member 710 fit against the two sides of the glass. The spring 711 in the buffer member 710 provides elastic clamping force through the baffle 712, which not only limits the lateral displacement of the glass, but also avoids rigid contact damage. The design of the limiting roller 719 ensures that the glass will not come into contact with the clamping member 714 during rotational grinding and thus will not break.

[0041] Please refer to Figure 1, Figure 2 , Figure 3 and Figure 6 The second limiting component 12 includes a fixing frame 1201, which is fixedly installed on the top of the housing 4. A threaded sleeve 1202 is fixedly installed on the top of the fixing frame 1201. A threaded rod 1203 is threadedly connected to the inner cavity of the threaded sleeve 1202. A rotating disk 1204 is fixedly installed on the top of the threaded rod 1203, and a limiting element 1205 is fixedly installed on the bottom of the threaded rod 1203. A fixing ring 1206 is sleeved on the surface of the threaded sleeve 1202, and the side of the fixing ring 1206 near the fixing frame 1201 is fixedly connected to the fixing frame 1201. After lateral limiting, rotating the rotating disk 1204 of the second limiting component 12 drives the threaded rod 1203 to move downward along the threaded sleeve 1202. The threaded rod 1203 drives the limiting element 1205 to descend and press against the glass surface. The pressing height is controlled by adjusting the number of rotations of the threaded rod 1203 to adapt to different glass thicknesses and to limit the jump or deviation of the glass during edge grinding in the longitudinal direction.

[0042] In operation, compared to existing single-edge grinding machines that only use the bottom suction cup 6 to limit and fix the glass, relying on the suction force of the suction cup 6 to position the glass, the glass is prone to shifting in the longitudinal direction perpendicular to the grinding direction due to friction generated by the contact between the grinding wheel and the glass, and vibrations from equipment operation. Because of the lack of effective constraint on the sides and top of the glass, the suction force of the suction cup 6 is insufficient to counteract the longitudinal force, causing changes in the relative position of the glass edge and the grinding wheel. This solution uses a base 1 as the load-bearing foundation, support legs 2 to enhance overall stability, and a motor 3 as the power source fixed to one side of the base 1. Its output shaft is connected to the rotating shaft of the suction cup 6 via a coupling. When the motor 3 starts, the power drives the suction cup 6 to rotate uniformly around its own axis via the coupling, and the glass is placed on the surface of the suction cup 6. After the glass is exposed, the suction cup 6 generates negative pressure to adhere to the bottom of the glass, causing the glass to rotate synchronously with the suction cup 6. The electric telescopic rod 702 of the first limiting component 7 is installed inside the housing 4. After activation, it pushes the toothed plate 704 to move laterally along the sliding rod 717. Through the meshing transmission between the toothed plate 704 and the rotating gear 705, the adjusting plate 707 is driven to rotate. The guide groove 708 of the adjusting plate 707 drives the movable rod 709 to extend synchronously towards the glass along the limiting groove 5 of the housing 4, so that the clamping member 714 and the limiting roller 719 at the end of the buffer member 710 fit against the two sides of the glass. The spring 711 in the buffer member 710 provides elastic clamping force through the baffle 712, which not only limits the lateral displacement of the glass, but also avoids rigid contact damage. The design of the limiting roller 719 prevents the glass from contacting the clamping member 714 and breaking during rotational grinding.

[0043] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
