Description

Technical Field

[0001] This utility model belongs to the field of glass production and relates to a glass production straight edge grinding device. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of small amounts of auxiliary materials. Its main component is silicon dioxide and other oxides. The chemical composition of ordinary glass is Na₂SiO₃, CaSiO₃, SiO₂, or Na₂O·CaO·6SiO₂, etc., with silicate complex salts as its main components. It is an amorphous solid with an irregular structure. It is widely used in buildings for wind insulation and light transmission, and is a mixture. There are also colored glasses, which exhibit color due to the incorporation of certain metal oxides or salts, and tempered glass, which is produced through physical or chemical methods.

[0003] For example, patent (CN222289641U) discloses a grinding device for glass edges, which describes that "it includes a grinding device body, a support block is provided on one side of the upper surface of the grinding device body, a groove is opened on one side surface of the support block, a grinding part mounting block is slidably connected inside the groove, a grinding motor is installed inside the grinding part mounting block, a grinding block is provided at the lower end of the grinding motor, an upper suction cup mounting block is provided on one side of the grinding part mounting block, a suction cup motor is installed inside the upper suction cup mounting block, a rotating shaft is provided at the lower end of the suction cup motor, a suction cup mounting plate is provided at the lower end of the rotating shaft, and upper suction cups are provided on both sides of the lower end of the suction cup mounting plate. By squeezing and adsorbing the glass with multiple upper and lower suction cups, the stability of the glass grinding can be improved when the glass volume is large, and it can also adapt to the grinding of glass of different sizes, improving convenience and applicability."

[0004] The existing technology has the following technical defects: After the glass is produced, its edges and corners need to be polished to increase the safety of the glass. However, glass has four edges. The above-mentioned device and most existing devices can only process two symmetrical edges of the glass. After processing, the glass needs to be manually changed to process the other two edges. The speed of manual edge changing is slow and it is easy to affect the efficiency of glass processing. Utility Model Content

However, glass has four edges, and the aforementioned devices and most existing devices can only process two symmetrical edges. After processing, the glass needs to be manually changed to process the other two edges. Manual edge changing is slow and easily affects the efficiency of glass processing. To overcome the shortcomings of the prior art, this invention provides a straight-edge polishing device for glass production.

A drive gear is fixed to the outer side of the top of the drive shaft. A transmission gear is fixed at a position corresponding to the drive gear on the rotating shaft. The transmission gear is meshed with the drive gear.

[0008] A transmission worm gear is fixed to the outer side of the lower end of the transmission shaft. A transmission rod is rotatably connected to the inner side of the grinding table at a position corresponding to the transmission worm gear. One end of the transmission rod extends to the outer side of the grinding table. A second handle is fixed to the outer end of the transmission rod located on the outer side of the grinding table. A drive worm is fixed to the other end of the transmission rod. The drive worm is meshed with the transmission worm gear.

[0009] A fixed bearing is fixed to the outer side of one end of the rotating shaft located inside the grinding table. A movable frame is fixed to the outer side of the fixed bearing. The movable frame is slidably connected to the grinding table. A first fixed rod is fixed to the end of the movable frame away from the fixed bearing. The end of the first fixed rod away from the movable frame extends to the outer side of the grinding table. A first handle is fixed to the end of the first fixed rod located on the outer side of the grinding table.

[0010] A second fixing rod is provided on the inner side of the grinding table and below the first fixing rod. The second fixing rod is slidably connected to the grinding table. The end of the second fixing rod away from the grinding table extends to the outer side of the grinding table. A lifting ball is fixed to the end of the second fixing rod on the outer side of the grinding table. A fixing frame is fixed to the other end of the second fixing rod. The fixing frame is slidably connected to the grinding table. A second rack is fixed to both sides of the top of the fixing frame. A fixing plate is slidably connected on the inner side of the placement plate and corresponding to the rotation axis. A limit block is fixed to the top of the fixing plate. A first rack is fixed to the side of the fixing plate away from the rotation axis. A connecting shaft is rotatably connected on the inner side of the grinding table and near the first rack. A first gear is fixed at the middle position of the connecting shaft and corresponding to the first rack. The first gear meshes with the first rack. A second gear is fixed to both ends of the connecting shaft. The second gear meshes with the second rack.

[0011] A return spring is fitted on the outer side of the second fixing rod near the fixing frame. One end of the return spring is fixedly connected to the fixing frame, and the other end of the return spring is fixedly connected to the grinding table.

[0012] Working process or working principle: During operation, the glass is first placed on top of the placement plate. The glass is initially positioned using a suction cup on the top of the placement plate. Then, by pushing the first handle, the first handle, through the first fixed rod and the moving frame, drives the fixed bearing and the rotating shaft towards the placement plate. When the rotating shaft contacts the limiting block, it presses against the limiting block, causing the limiting block to move the fixed plate and the first rack away from the limiting block. As the first rack moves, it drives the connecting shaft to rotate through the first gear meshing with it. The rotation of the connecting shaft drives the second gear to rotate simultaneously. The rotation of the second gear, through the second rack meshing with it, drives the fixed frame away from the rotating shaft. The movement of the fixed frame compresses the return spring, causing it to elastically deform. When the rotating shaft disengages from the limiting block, the elastic force of the return spring drives the fixed frame to move in the opposite direction. This causes the second gear, through the connecting shaft, to drive the first gear to rotate in the opposite direction, thereby moving the first rack and the fixed plate towards the limiting block. When the device is activated, it moves the limiting block simultaneously, thereby limiting the rotation shaft to prevent horizontal movement. While the limiting block is controlling the rotation shaft, the transmission gear and drive gear mesh. Then, by activating the electric telescopic rod, the telescopic end of the rod moves the connecting frame and fixed suction cups closer to the placement plate. Multiple fixed suction cups then clamp and fix the glass. The glass is then polished by the grinding mechanism. When it is necessary to change the glass edge for grinding, the electric telescopic rod is activated first, causing the connecting frame and fixed suction cups to release the downward clamping effect on the glass. Then, by rotating the second handle, the second handle drives the drive worm gear via the transmission rod. When the drive worm gear rotates, it drives the transmission shaft fixed to the transmission worm gear to rotate. When the transmission shaft rotates, it drives the drive gear to rotate. When the drive gear rotates, it drives the rotation shaft via the transmission gear, thus rotating the placement plate simultaneously. This allows the glass at the top of the placement plate to rotate, completing the edge-changing operation.

[0013] Compared with the prior art, the beneficial effects of this utility model are: through the cooperative structural design of the placement plate, the rotating shaft and the rotating component, the rotating component can drive the rotating shaft to rotate, thereby rotating the glass located at the top of the placement plate, which facilitates the replacement of the glass side without having to remove the glass and replace it manually. At the same time, it facilitates the placement and removal of the glass, improves the work efficiency of glass polishing, and enhances the practicality of the device.

[0014] The design of the electric telescopic rod, connecting frame and fixed suction cup allows the glass to be adsorbed and held by the fixed suction cup during the polishing process, preventing the glass from moving and improving the stability of the glass during polishing.

[0020] Example 1

[0021] like Figures 1-4 As shown, the device includes a grinding table 1, a placement plate 2 at the top of the grinding table 1, a grinding mechanism 3 at the lower end of the top of the grinding table 1, an electric telescopic rod 4 fixed at the lower end of the top of the grinding table 1 corresponding to the placement plate 2, and a connecting frame 5 fixed at the telescopic end of the electric telescopic rod 4. To facilitate clamping and fixing the glass, multiple suction cups 6 are fixed at the top of the grinding table 1 and the end of the connecting frame 5. To facilitate the glass-changing operation by rotating the placement plate 2, a rotating shaft 8 is fixed at the lower end of the placement plate 2. The rotating shaft 8 is slidably connected to the grinding table 1. A rotating assembly is provided on the inner side of the grinding table 1 at the position corresponding to the rotating shaft 8 for rotating the placement plate 2. To facilitate the collection of debris generated during grinding, a collection box 7 is detachably connected to the top of the grinding table 1 below the placement plate 2.

[0022] The rotating assembly includes a drive shaft 11, which is located inside the grinding table 1 and close to the placement plate 2. The drive shaft 11 is rotatably connected to the grinding table 1. In order to facilitate the rotation of the rotating shaft 8 when the drive shaft 11 rotates, a drive gear 14 is fixed on the outer side of the top end of the drive shaft 11. A drive gear 15 is fixed at the position corresponding to the drive gear 14 on the rotating shaft 8. The drive gear 15 is meshed with the drive gear 14.

[0023] A transmission worm gear 18 is fixed to the outer side of the lower end of the transmission shaft 11. A transmission rod 16 is rotatably connected to the inner side of the grinding table 1 at a position corresponding to the transmission worm gear 18. One end of the transmission rod 16 extends to the outer side of the grinding table 1. To facilitate the rotation of the transmission rod 16, a second handle 19 is fixed to the outer end of the transmission rod 16 on the grinding table 1. To facilitate the rotation of the transmission shaft 11 when the transmission rod 16 rotates, a drive worm 17 is fixed to the other end of the transmission rod 16. The drive worm 17 is meshed with the transmission worm gear 18.

[0024] To facilitate the movement of the rotating shaft 8 without affecting its rotation, a fixed bearing 9 is fixed to the outer side of one end of the rotating shaft 8 located inside the grinding table 1. To facilitate the movement of the rotating shaft 8, a movable frame 10 is fixed to the outer side of the fixed bearing 9. The movable frame 10 is slidably connected to the grinding table 1. A first fixed rod 12 is fixed to the end of the movable frame 10 away from the fixed bearing 9. The end of the first fixed rod 12 away from the movable frame 10 extends to the outer side of the grinding table 1. To facilitate the movement of the first fixed rod 12, a first handle 13 is fixed to the end of the first fixed rod 12 located on the outer side of the grinding table 1. This allows the placement plate 2 to be moved horizontally, thereby facilitating the handling and placement of the glass and improving the ease of handling.

[0025] Through the coordinated structural design of the placement plate 2, the rotating shaft 8, and the rotating assembly, the rotating assembly can drive the rotating shaft 8 to rotate, thereby rotating the glass located at the top of the placement plate 2. This facilitates the replacement of the glass with a different side without having to remove the glass manually. It also makes it easier to place and pick up the glass, improving the efficiency of glass polishing and enhancing the practicality of the device.

[0026] Example 2

[0027] like Figure 3 and Figure 4As shown, a second fixing rod 20 is provided on the inner side of the grinding table 1 and below the first fixing rod 12. The second fixing rod 20 is slidably connected to the grinding table 1. The end of the second fixing rod 20 away from the grinding table 1 extends to the outer side of the grinding table 1. To facilitate the movement of the second fixing rod 20, a lifting ball 21 is fixed to the end of the second fixing rod 20 on the outer side of the grinding table 1, and a fixing frame 25 is fixed to the other end of the second fixing rod 20. The fixing frame 25 is slidably connected to the grinding table 1, and a second rack 26 is fixed to both sides of the top of the fixing frame 25. A fixing plate 23 is slidably connected on the inner side of the placement plate 2 and at a position corresponding to the rotating shaft 8. To limit the horizontal movement of the rotating shaft 8, a limit block 22 is fixed to the top of the fixing plate 23. The fixing plate 23 is located away from the rotating shaft 8. A first rack 24 is fixed to one side of shaft 8. A connecting shaft 28 is rotatably connected to the inner side of the grinding table 1 near the first rack 24. In order to drive the connecting shaft 28 to rotate when the first rack 24 moves, a first gear 27 is fixed at the middle position of the connecting shaft 28 and at the position corresponding to the first rack 24. The first gear 27 is meshed with the first rack 24. A second gear 29 is fixed at both ends of the connecting shaft 28. The second gear 29 is meshed with the second rack 26. In order to limit the fixed frame 25 and prevent the fixed frame 25 from moving at will, a return spring 30 is sleeved on the outer side of the second fixed rod 20 near the fixed frame 25. One end of the return spring 30 is fixedly connected to the fixed frame 25, and the other end of the return spring 30 is fixedly connected to the grinding table 1.

[0028] When the rotating shaft 8 moves to contact the limiting block 22, the rotating shaft 8 will squeeze the limiting block 22, causing the limiting block 22 to drive the fixing plate 23 and the first rack 24 to move away from the limiting block 22. When the first rack 24 moves, it drives the connecting shaft 28 to rotate through the first gear 27 meshing with it. When the connecting shaft 28 rotates, it drives the second gear 29 to rotate simultaneously. When the second gear 29 rotates, it drives the fixing frame 25 to move away from the rotating shaft 8 through the second rack 26 meshing with it. When the fixing frame 25 moves, it will... The return spring 30 is compressed, causing it to elastically deform. When the rotating shaft 8 moves to the point of disengagement from the limiting block 22, the elastic action of the return spring 30 drives the fixed frame 25 to move in the opposite direction. This causes the second gear 29 to drive the first gear 27 to rotate in the opposite direction via the connecting shaft 28, thereby driving the first rack 24 and the fixed plate 23 to move closer to the limiting block 22. When the fixed plate 23 moves, it drives the limiting block 22 to move simultaneously, thus limiting the rotating shaft 8 and preventing it from moving horizontally.
