Description
Technical Field
[0001] This utility model relates to the field of glass edging technology, specifically to a glass edging processing device with anti-breakage function. Background Technology
[0002] Glass edging machines are among the earliest and most widely used mechanical equipment in glass deep processing, primarily used for smoothing glass. The current working process of a glass edging machine is as follows: glass is conveyed to the grinding wheel assembly via a conveyor belt. The grinding wheel assembly, driven by a moving slide, contacts the glass and performs edging according to the set cutting amount. After edging is completed, the operator manually moves to the other side for edging or the glass enters the next process step of the production line. During glass processing, securing the glass is particularly important; improper securing can easily lead to glass breakage.
[0003] According to a public notice (No. CN218487982U) regarding a glass edging machine for preventing glass breakage, the above application uses an air pump to fix the upper surface of the glass by placing it on the surface of the lower suction cup and then moving the upper suction cup downwards. This prevents the glass from breaking due to displacement during the edging process. The machine performs high-precision edging. After edging one edge, the air pump in the rotating mechanism is activated, causing the rack and gear to mesh and rotate the lower and upper suction cups at the top of the rotating shaft. This changes the edging surface of the glass, rotating it 90 degrees. Repeating these steps completes the edging of all four sides, simplifying the glass edging process and solving the problems of easy breakage, burrs, and low precision in existing glass edging techniques.
[0004] However, directly performing high-precision edge grinding results in a large difference in mesh count, causing a sharp reduction in the amount of grinding. This prevents the edge stress from being gradually released and instead forces cracks into the glass, leading to glass breakage. Utility Model Content
[0005] The purpose of this invention is to provide a glass edging processing device with anti-breakage function to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a glass edging processing device with anti-breakage function, comprising a worktable, a side plate fixedly connected to the surface of the worktable, a groove formed on the side wall of the side plate, a drive assembly disposed inside the groove, a grinding assembly disposed at the bottom of the drive assembly, the grinding assembly comprising an L-plate, a disc rotatably connected to the inner side of the L-plate, three sets of arrayed mounting shafts rotatably connected to the surface of the disc, three sets of grinding rollers with different mesh sizes fixedly mounted on the outer walls of the three sets of mounting shafts, a motor fixedly connected to the back of the L-plate, the output shaft of the motor passing through and rotatably connected to the inner side of the L-plate and fixedly connected to the end of the disc.

[0017] like Figures 1-3 As shown, this utility model provides a technical solution: a glass edging processing device with anti-breakage function, including a worktable 1, a support leg 11 fixedly connected to the bottom surface of the worktable 1, a side plate 2 fixedly connected to the surface of the worktable 1, a sliding groove 3 opened on the side wall of the side plate 2, a drive assembly 4 arranged inside the sliding groove 3, a grinding assembly 5 arranged at the bottom of the drive assembly 4, the side plate 2 being vertically fixed to the surface of the worktable 1, and the sliding groove 3 providing a sliding track for the support plate 41 to ensure that the grinding assembly 5 moves only in a direction parallel to the edge of the glass.
[0018] The grinding assembly 5 includes an L-plate 51. A disc 52 is rotatably connected to the inner side of the L-plate 51. Three sets of arrayed mounting shafts 53 are rotatably connected to the surface of the disc 52. Three sets of grinding rollers 54 with different grit sizes are fixedly mounted on the outer walls of the three sets of mounting shafts 53. Transmission wheels 55 are fixedly connected to the outer walls of the mounting shafts 53. The three sets of transmission wheels 55 are connected by synchronous transmission. An electric motor that drives the grinding rollers 54 to rotate is installed inside the disc 52. A motor 56 is fixedly connected to the back of the L-plate 51. The output shaft of the motor 56 passes through and is rotatably connected to the inner side of the L-plate 51 and fixedly connected to the end of the disc 52. The L-plate 51 is the mounting bracket of the grinding assembly 5, providing rotational support for the disc 52. The disc 52 can rotate around its own axis and is driven by the motor 56. Each set of mounting shafts 53 corresponds to one grinding roller 54. The three sets of polishing rollers 54 are configured with coarse, medium, and fine grit, which can be switched using a rotating disc 52. Coarse grinding is used to quickly remove burrs from the glass, while medium and fine grinding are used to refine the edges and prevent edge chipping caused by single-roller polishing. The electric motor inside the disc 52 provides rotational power to the polishing rollers 54, and the three sets of polishing rollers 54 rotate synchronously through a timing belt connection. The drive assembly 4 includes a support plate 41, which is slidably connected inside the slide groove 3. A through hole is provided on the side wall of the support plate 41, and a lead screw 42 is threaded into the through hole. The end of the lead screw 42 is rotatably connected to the inner wall of the slide groove 3. A second motor 43 is fixedly connected to the end of the side plate 2. The output shaft of the second motor 43 passes through and is rotatably connected to the inner wall of the slide groove 3, and is fixedly connected to the end of the lead screw 42. By starting the second motor 43, the lead screw 42 is rotated, driving the support plate 41 to move horizontally along the slide groove 3 via threaded transmission, thus achieving precise control of the horizontal position of the grinding assembly 5. A cylinder 44 is fixedly connected to the surface of the support plate 41. The output shaft of the cylinder 44 passes through and is slidably connected to the bottom surface of the support plate 41, and is fixedly connected to the surface of the L-plate 51. By extending and retracting the cylinder 44, the grinding assembly 5 moves up and down as a whole, allowing adjustment of the contact pressure between the grinding roller 54 and the glass edge according to the glass thickness.
[0019] A fixing component 6 is provided on the surface of the workbench 1. The fixing component 6 includes a back plate 61, which is fixedly connected to the surface of the workbench 1. A groove 62 is formed on the surface of the workbench 1. A T-shaped plate 63 is slidably connected inside the groove 62. A threaded rod 64 is rotatably connected to the side wall of the T-shaped plate 63. The threaded rod 64 passes through and is connected to the side wall of the workbench 1. A rotating wheel 65 is fixedly connected to the end of the threaded rod 64. The groove 62 provides a sliding guide for the T-shaped plate 63, ensuring the stability of the movement direction of the T-shaped plate 63. The T-shaped plate 63 is slidably fitted into the groove 62 of the workbench 1. When the rotating wheel 65 is rotated, the threaded rod 64 pushes the T-shaped plate 63 towards the back plate 61 through threaded transmission, clamping the glass.
[0020] In this invention, during use, the glass to be edged is first placed flat on the surface of the workbench 1, so that one edge of the glass is in contact with the back plate 61 in the fixing assembly 6, completing the initial positioning. Then, the rotating wheel 65 is rotated, and the rotating wheel 65 drives the threaded rod 64 to rotate synchronously. Since the threaded rod 64 is threadedly connected to the side wall of the workbench 1, and the T-shaped plate 63 is rotatably connected to the threaded rod 64 and simultaneously slidably fitted in the groove 62, the rotation of the threaded rod 64 will be converted into the linear movement of the T-shaped plate 63 along the groove 62, causing the T-shaped plate 63 to move closer to the back plate 61 until the T-shaped plate 63 and the back plate 61 together clamp the glass, preventing the glass from shifting during the grinding process.
[0021] Based on the precision requirements of glass edge grinding, start motor 56. The output shaft of motor 56 drives disk 52 to rotate around its own axis until the grinding roller 54 of the corresponding grit on disk 52 rotates to the working position facing the edge of the glass. If it is necessary to quickly remove the glass burrs, select coarse grinding roller 54; if it is necessary to refine the edge and avoid cracking, switch to medium or fine grinding roller 54.
[0022] Next, cylinder 44 is started. The output shaft of cylinder 44 drives the grinding assembly 5 to move up and down as a whole. Based on the thickness of the glass, the height of the grinding roller 54 is adjusted so that the outer wall of the grinding roller 54 is in contact with the edge of the glass to be ground. The contact pressure between the grinding roller 54 and the edge of the glass is controlled by the thrust of the output shaft of cylinder 44 to ensure that the pressure is moderate.
[0023] The electric motor inside the disc 52 is started. The electric motor drives three sets of transmission wheels 55 to rotate synchronously via a synchronous belt. The transmission wheels 55 drive the mounting shaft 53 and the grinding roller 54 fixed on the shaft to rotate at high speed, so that the grinding roller 54 enters the working state. Then, the second motor 43 is started. The output shaft of the second motor 43 drives the lead screw 42 to rotate on the inner wall of the slide groove 3. The rotation of the lead screw 42 is converted into the horizontal movement of the support plate 41 along the slide groove 3 through the thread transmission, which in turn drives the entire grinding assembly 5 to move at a uniform speed along the glass edge, so as to achieve continuous grinding of the glass edge.
[0024] To further improve the edge grinding accuracy, the initial edge grinding can be completed by the coarse grinding roller 54. Then, the electric motor and motor 2 43 can be turned off, and motor 1 56 can be restarted to switch to the medium grinding roller 54. The height adjustment of cylinder 44 and the drive process of motor 2 43 can be repeated to perform medium grinding. After the medium grinding is completed, the fine grinding roller 54 can be switched to perform fine grinding. By gradually refining the multi-grit grinding roller 54, the edge cracking problem that may be caused by single-roller grinding can be effectively avoided, while improving the smoothness of the glass edge.
[0025] After the glass edge is polished, the electric motor, motor 43, and cylinder 44 inside the disc 52 are turned off in sequence. Cylinder 44 drives the polishing assembly 5 to return to its original position, away from the glass edge. Then, the rotating wheel 65 is rotated in the opposite direction, causing the T-shaped plate 63 to move along the groove 62 away from the back plate 61, releasing the clamping state on the glass. Finally, the polished glass is removed from the worktable 1, completing the entire edge polishing operation.
[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
