Technical Field
[0001] This utility model relates to the field of tempered glass production technology, and in particular to an edge grinding device for tempered glass production. Background Technology
[0002] Tempered glass is a type of safety glass. It is actually a prestressed glass. To improve its strength, chemical or physical methods are typically used to create compressive stress on the glass surface. When the glass is subjected to external force, this surface stress is first neutralized, thus improving its load-bearing capacity and enhancing its resistance to wind pressure, temperature changes, and impacts. An edging machine can polish the edges of tempered glass, removing burrs and making it smoother. Chinese utility model patent, authorized publication number "CN218136964U", discloses a tempered glass edging machine, including: a worktable, a fixed frame, and rollers. The top of the worktable... A retainer is welded to the side, and a motor is installed at the top inside the retainer. The motor has a connecting rod. A first bearing is embedded in the fixed frame, and a movable rod is rotatably installed on the first bearing. A movable hole is opened on one side of the worktable of the retainer. Second bearings are installed in a straight line at equal intervals on both sides of the worktable inside the movable hole. A bracket is rotatably installed at the opposite end of the two rows of second bearings. Rollers are installed at the opposite end of the two rows of brackets. Support frames are welded to both sides of the bottom of the worktable. Connecting rods are welded to the opposite side of the two support frames. A collection pipe is installed at the opposite end of the two connecting rods.
[0003] The device in the aforementioned patent has the advantage of facilitating the collection of tempered glass fragments generated during edge grinding, thus reducing the difficulty of cleaning. However, the above technical solution still has certain defects. The device does not limit the glass, and the glass is prone to displacement when grinding the edge. The displacement of the glass will cause the grinding trajectory to deviate from the preset path, resulting in uneven grinding amount at the edge of the glass and reducing the grinding quality. Therefore, this utility model proposes a new solution. Utility Model Content

[0018] Please see Figure 1-5This utility model provides a technical solution: a tempered glass edging device, including a processing chamber 1 and an edging assembly. The edging assembly is disposed inside the processing chamber 1. The edging assembly includes a rotating shaft 2, which is rotatably connected inside the processing chamber 1. A glass placement tray 3 is fixedly connected to the upper end of the rotating shaft 2. A first hydraulic rod 7 is fixedly connected inside the processing chamber 1. A pressure plate connecting frame 8 is fixedly connected to the output end of the first hydraulic rod 7. A glass pressure plate 10 is rotatably connected to the lower end of the pressure plate connecting frame 8. A guide frame 12 is slidably connected inside the processing chamber 1. A second drive motor 15 is fixedly connected to the front end of the guide frame 12. A threaded rod 16 is fixedly connected to the output end of the second drive motor 15. A slide table 18 is threadedly sleeved on the surface of the threaded rod 16. The slide table 18 is slidably connected to the guide frame 12. A fixed seat 19 is fixedly connected to the upper end of the slide table 18. A polishing machine 20 is installed on the upper end of the fixed seat 19.
[0019] Two guide rods 9 are fixedly connected to the upper end of the pressure plate connecting frame 8, and both guide rods 9 are slidably connected to the processing chamber 1.
[0020] A first drive motor 4 is fixedly connected inside the processing chamber 1. A first gear 5 is fixedly connected to the output end of the first drive motor 4. A second gear 6 is fixedly connected to the surface of the rotating shaft 2. The first gear 5 and the second gear 6 mesh.
[0021] Two corrugated plates 17 are provided at the upper end of the guide frame 12. The two ends of the two corrugated plates 17 are fixedly connected to the guide frame 12 and the slide table 18, respectively. The middle part of the two corrugated plates 17 is slidably connected to the guide frame 12 at the contact position with the guide frame 12.
[0022] The machining chamber 1 is fixedly connected to a second hydraulic rod 11. The output end of the second hydraulic rod 11 is fixedly connected to the guide frame 12. Two slide grooves 13 are opened on the surface of the machining chamber 1. Two sliders 14 are fixedly connected to the lower end of the guide frame 12. The two sliders 14 are slidably connected to the corresponding slide grooves 13 respectively.
[0023] Support pads 21 are fixedly connected to the surfaces of both the glass placement tray 3 and the glass pressing tray 10.
[0024] When using the device, the operator places the tempered glass to be ground on the glass placement tray 3. The support pad 21 on the surface of the glass placement tray 3 can initially buffer the impact when the glass is placed and increase the friction. The first hydraulic rod 7 is activated, and its output end pushes the pressure plate connecting frame 8 to move vertically downward along the guide rod 9. The sliding connection between the guide rod 9 and the processing chamber 1 ensures that the pressure plate connecting frame 8 moves smoothly until the support pad 21 on the surface of the glass pressure plate 10 is in close contact with the upper surface of the glass. At this time, the glass is axially fixed under the clamping of the glass placement tray 3 and the glass pressure plate 10. The elastic material of the support pad 21 can not only prevent the glass surface from being damaged by pressure, but also prevent the glass from being horizontally displaced during subsequent grinding.
[0025] The first drive motor 4 is started, and its output end drives the first gear 5 to rotate. Through the meshing transmission between the first gear 5 and the second gear 6, the rotating shaft 2 rotates synchronously with the second gear 6, thereby driving the glass placement tray 3 and the clamped tempered glass to rotate at a uniform speed. Since the glass pressure plate 10 and the pressure plate connecting frame 8 are rotatably connected, the glass pressure plate 10 can rotate synchronously with the glass when the glass rotates, avoiding additional frictional resistance to the glass.
[0026] According to the glass size and the required edge width, the second hydraulic rod 11 is activated. Its output end pushes the guide frame 12 to slide horizontally along the slide groove 13 on the surface of the processing chamber 1 through the lower slider 14 until the polishing machine 20 approaches the preset polishing area of the glass edge. The cooperation between the slide groove 13 and the slider 14 ensures that the movement trajectory of the guide frame 12 is accurate and avoids lateral deviation.
[0027] The second drive motor 15 is started, and its output end drives the threaded rod 16 to rotate. Through the threaded transmission, the slide table 18 slides longitudinally along the guide frame 12. The guide frame 12 guides and limits the slide table 18, further adjusting the contact distance between the polishing machine 20 and the glass edge until the polishing head and the glass edge are precisely in contact. During this process, the corrugated plate 17 between the guide frame 12 and the slide table 18 deforms as the slide table 18 moves, which can absorb the slight vibration during polishing, improve the stability of equipment operation, and at the same time prevent glass fragments from falling into the interior of the guide frame 12 during glass processing, preventing any impact when the slide table 18 and the threaded rod 16 are running.
[0028] Circular glass edge grinding: The glass rotates at a constant speed under the drive of the glass placement plate 3, and the grinding machine 20 keeps its position fixed. The continuous grinding of the edge is achieved through the circumferential motion of the glass, thus completing the circumferential edge grinding of the circular glass.
[0029] Square glass edge grinding: After fixing the square glass between the glass placement plate 3 and the glass pressure plate 10, drive the glass to rotate synchronously with the glass placement plate 3 and the glass pressure plate 10, and adjust it so that one side of the glass is parallel to the guide frame 12; drive the fixed base 19 and the grinding machine 20 to move longitudinally on the guide frame 12 through the slide table 18, and at the same time cooperate with the lateral sliding of the guide frame 12 under the guidance of the slider 14 and the slide groove 13, so that the position of the grinding machine 20 can be flexibly adjusted to precisely align with the side of the square glass, and complete the grinding of one side.
[0030] Repeat the above operations of rotating the glass and adjusting the position of the grinding machine 20 to grind the edges of the four sides of the square glass in sequence. By adjusting the lateral position of the guide frame 12 in the processing chamber 1, it can be adapted to square glass of different side lengths, expanding the applicability of the device. After the position of the grinding machine 20 is adjusted, the grinding machine 20 is started, and its grinding head grinds the edge of the rotating glass. Since the edge of the glass always maintains stable contact with the grinding head during the rotation process, and the position of the grinding machine 20 is fixed by the above adjustment mechanism, continuous and uniform edge grinding of the glass edge can be achieved, removing burrs and forming a smooth edge.
[0031] After the edge grinding is completed, the grinding machine 20, the first drive motor 4 and the second drive motor 15 are turned off in sequence, and the first hydraulic rod 7 is started in reverse to make the glass pressure plate 10 rise and detach from the glass surface, so that the operator can take out the ground glass; the second hydraulic rod 11 is started in reverse to make the guide frame 12 drive the edge grinding assembly to reset, which is convenient for the next operation.
[0032] Furthermore, this device achieves bidirectional clamping of tempered glass through the cooperation of the glass placement plate 3 and the glass pressure plate 10. The first hydraulic rod 7 drives the pressure plate connecting frame 8 to move smoothly along the guide rod 9, ensuring uniform and stable clamping force; ensuring uniform grinding amount of the glass edge, significantly improving the edge grinding quality. By rotating the glass, combined with the lateral sliding of the guide frame 12 and the longitudinal sliding of the slide table 18, the position of the grinding machine 20 can be flexibly adjusted; for round glass, continuous edge grinding can be achieved by rotating the glass; for square glass, the side angle can be adjusted by rotating the glass, and grinding can be completed side by side. It can also adapt to glass of different specifications and sizes, solving the problem of limited adaptability of traditional devices to glass shape and size.

The middle part is slidably connected to guide frame 12.
