Technical Field
[0001] This utility model relates to the field of glass production technology, specifically to a glass edge grinding device. Background Technology
[0002] Glass is a non-crystalline inorganic material made primarily from raw materials such as quartz sand, soda ash, limestone, and feldspar. It is a solid that retains a liquid structure after the molten material is cooled. After glass production, grinding equipment is used to chamfer its edges and corners. Chamfering the edges and corners can improve the quality of glass products in many aspects, including safety, performance, practicality, and aesthetics.
[0003] The existing utility model patent with authorization publication number CN215617049U discloses an edge grinding device for photovoltaic glass production, including a load-bearing plate, a connecting plate fixedly installed at the middle position of the front end of the load-bearing plate, a control plate fixedly installed at the middle position of the front end of the connecting plate, a protective cover fixedly installed at the middle position of the top of the connecting plate, and an electric slide rail opened at the middle position of the top of the load-bearing plate. This invention protects the user's face with a protective cover during operation, preventing glass shards from flying during grinding. It also secures the glass with a powerful suction cup at the bottom and uses an electric telescopic rod to press and fix the glass with a pressing plate. This effectively reduces vibration during grinding. Furthermore, the position of the second motor can be adjusted via the positioning hole to grind glass of different lengths. However, this glass edge grinding device requires manual loosening of bolts to adjust the position of the second motor and the two grinding stones, which in turn requires manual tightening after adjustment. Additionally, grinding heads are typically fixed with bolts, making replacement cumbersome. Therefore, we propose a glass edge grinding device to solve these problems. Utility Model Content

[0005] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A glass edge grinding device includes a support plate. A conveying assembly, a grinding assembly, and a side-limiting assembly are mounted on the top of the support plate. The conveying assembly includes a frame fixed to the top of the support plate. Four rollers (first type) and three rollers (second type) are rotatably connected to the inside of the frame via bearings. The grinding assembly includes a bracket fixed to the top of the support plate. Two connecting seats are provided between the inner walls of both sides of the bracket. A rotating shaft is rotatably connected to each connecting seat via bearings. A connecting piece is fixed to the bottom of each rotating shaft. A grinding head is detachably mounted on the bottom end of each connecting piece. A bidirectional lead screw is rotatably connected to the bracket via bearings. The two connecting seats are threaded onto the surface of the bidirectional lead screw. Two guide rods are fixed to the inner walls of both sides of the bracket, and the two connecting seats slide on the surfaces of the two guide rods.
[0006] Furthermore, the connector includes a support base fixed to the bottom of the rotating shaft, the grinding head being limited and snapped into the bottom of the support base, a gear ring 1 being rotatably connected inside a rotating groove opened at the top of the support base, a nut placed on the top of the support base on the outer side of the gear ring 1, four bolts cooperating with the nuts being fixed at the top of the grinding head, the nuts being screwed onto the corresponding bolts, a gear ring 2 being fixed on the surface of each nut, the gear ring 2 being meshed with the gear ring 1, and an operating plate inside the gear ring 1.
[0007] Furthermore, the top of the support is fixed with four covers for limiting the position of the nut.
[0008] Furthermore, a rotating ring is fixed to the top of the support base, and an annular rail adapted to the rotating ring is fixed to the bottom of the connecting base.
[0009] Furthermore, two of the rollers have sprockets fixed to their surfaces, and the two sprockets are connected by a chain drive.
[0010] Furthermore, the side limiting assembly includes four guide rails fixed to the bottom of the support plate, two movable seats slidably connected between corresponding two guide rails, and limiting rollers rotatably connected to the top of each of the four movable seats via bearings.

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, an embodiment of the present invention provides a glass edge grinding device, including a support plate 1. The top of the support plate 1 is equipped with a conveying component 2, a grinding component 3, and a side limiting component 4. The conveying component 2 includes a frame 21 fixed to the top of the support plate 1. A motor is fixed to one side wall of the frame 21. The output end of the motor is fixedly connected to one end of one of the rollers 22. Four rollers 22 and three rollers 23 are rotatably connected inside the frame 21 through bearings. The surfaces of the four rollers 22 and the three rollers 23 are all provided with rubber sleeves, which can protect the glass. However, the rubber sleeves are not shown in the figure. The surfaces of two rollers 22 are fixed with sprockets 24. The two sprockets 24 are connected by a chain 25, so that the two outermost rollers 22 can be driven to rotate simultaneously under the action of a motor, which facilitates the movement and conveying of the glass. The support plate 1 is also provided with a tension adjustment component for adjusting the tension of the chain 25. However, the tension adjustment component is not shown in the figure.The grinding assembly 3 includes a bracket 31 fixed to the top of the support plate 1. A motor is fixed to one side wall of the bracket 31, and the output end of the motor is fixedly connected to one end of a bidirectional lead screw 36. Two connecting seats 32 are provided between the inner walls of both sides of the bracket 31, and a motor is fixed to each of the two connecting seats 32. The output end of the motor is fixedly connected to the top end of the corresponding rotating shaft 33. The rotating shaft 33 is rotatably connected to each connecting seat 32 via bearings. A connecting piece 34 is fixed to the bottom of each rotating shaft 33. A grinding head 35 can be detachably installed at the bottom end of each connecting piece 34. A bidirectional lead screw 36 is rotatably connected to the bracket 31 via bearings. The lead screw 36 and two connecting seats 32 are threadedly connected to the surface of the bidirectional lead screw 36. Two guide rods 37 are fixed to the inner walls of both sides of the bracket 31. The two connecting seats 32 slide on the surfaces of the two guide rods 37. The bidirectional lead screw 36 facilitates the determination that the two connecting seats 32 can move synchronously in opposite directions, while the guide rods 37 limit the movement of the connecting seats 32, preventing them from rotating synchronously with the bidirectional lead screw 36. In the process of using this glass edge grinding device, all motors used in the device are servo motors with self-locking functions, and they are placed in appropriate positions. Afterwards, the glass to be polished can be placed on the conveying assembly 2. Then, by adjusting the side limiting assembly 4, the side of the glass can be limited during movement. During polishing, the starting motor can drive the two outermost rollers 22 to rotate, thus conveying the glass. The other two rollers 22 and three rollers 23 provide auxiliary support for the glass during conveying. When the glass is conveyed to the two polishing heads 35, the starting motor can drive the bidirectional lead screw 36 to rotate. Then, the two polishing heads 35 can be controlled to adjust synchronously in opposite directions. The starting motor drives the two rollers 22 to rotate. The rotating shaft 33 rotates, which in turn drives the connecting piece 34 to rotate. The rotating connecting piece 34 then drives the grinding heads 35 to rotate. When the edges of the glass come into contact with the grinding heads 35 during transport, edge grinding can begin. When grinding the edges of the glass, the length of the glass to be ground should be greater than the distance between the grinding head 35 and the rollers used for limiting the edge in the side limiting assembly 4. Furthermore, if the glass disengages from the side limiting assembly 4 when it reaches the middle position, the rotating grinding heads 35 on both sides can limit its movement, preventing any deviation.
[0016] like Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the connector 34 includes a support base 341 fixed to the bottom of the rotating shaft 33. A rotating ring 348 is fixed to the top of the support base 341, and an annular rail 349 adapted to the rotating ring 348 is fixed to the bottom of the connector 32, which can provide auxiliary support for the support base 341 to make it more stable during rotation. The grinding head 35 is limited and locked to the bottom of the support base 341. A gear ring 342 is rotatably connected inside the rotating groove opened at the top of the support base 341. The outer side of the gear ring 342 is provided with A nut 343 is placed on top of a support base 341. Four covers 347 are fixed to the top of the support base 341 to limit the nut 343, preventing it from detaching from the support base 341. Four bolts 344 are fixed to the top of the grinding head 35 to mate with the nut 343. The nut 343 is screwed onto the corresponding bolt 344. A toothed ring 345 is fixed to the surface of each nut 343. The toothed ring 345 is aligned with a toothed ring... Ring 342 is engaged with the gear ring. Inside ring 342 is an operating plate 346. When the grinding head 35 needs to be removed and replaced, the operator inserts a hex wrench into the hexagonal blind hole of the operating plate 346. Then, the gear ring 342 can be rotated via the operating plate 346. Rotation of ring 342 drives the four gear rings 345 to rotate, which in turn drives the two nuts 343 to rotate. Rotation of the nuts 343 releases the restraint on the bolt 344, allowing the grinding head 35 to be removed and replaced. During installation, After the replaced grinding head 35 is snapped into the bottom of the support base 341, since the bottom of the support base 341 has four clearance through holes, the bolt 344 will not be interfered with when it slides through the support base 341. At this time, the bolt 344 will correspond to the corresponding nut 343. Then, the operator can use a tool to operate the toothed ring 342 to rotate in the opposite direction. After the toothed ring 342 rotates in the opposite direction, the four nuts 343 can be tightened onto the bolt 344 respectively. At this time, the replaced grinding head 35 can be limited and fixed.
[0017] like Figure 1 and Figure 10As shown, in some embodiments, the side limiting component 4 includes four guide rails 41 fixed to the bottom of the support plate 1. Two movable seats 42 are slidably connected between two corresponding guide rails 41. The tops of the four movable seats 42 are rotatably connected to limiting rollers 43 via bearings. Two bidirectional cylinders 44 are fixed to the bottom of the support plate 1. The top ends of the bidirectional cylinders 44 are fixedly connected to the corresponding movable seats 42. In use, by activating the two bidirectional cylinders 44 with self-locking function, the two movable seats 42 on both sides can be controlled to move synchronously in opposite directions. After the movable seats 42 move, they can drive the limiting rollers 43 to rotate respectively. The guide rails 41 can play a limiting, supporting and guiding role for the movable seats 42, so that they will be more stable during the sliding process. Four clearance openings adapted to the movable seats 42 are opened on the top of the support plate 1, so that the movable seats 42 will not be interfered with during the sliding process.
[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
