[0004] According to the aforementioned documents, the grinding head can be used to evenly grind the edges and corners of the billboard. However, after prolonged use, the surface of the grinding head will become smooth and can no longer be used for grinding. The staff in Yuyao need to replace the grinding head, but the grinding head in the aforementioned documents is fixed in place, making it inconvenient for the staff to disassemble it.

[0005] Therefore, we propose a billboard edge grinding machine. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Example: A billboard edge grinding machine, such as Figure 1 - Figure 6 As shown, the device includes a grinding chamber 1. Support connecting plates 10 are slidably installed on opposite sides of the inner wall of the grinding chamber 1. Connecting plates 14 are provided on opposite sides of the support connecting plates 10. A rotating rod 15 is threadedly connected to the connecting plates 14 via a bracket. The rotating rod 15 rotates with a ring 151 via a groove. First connecting rods 17 are rotatably connected to opposite sides of the ring 151 via first ball heads 16. Second connecting rods 17 are rotatably connected to second connecting rods 19 via second ball heads 18. A clamping plate 20 is fixedly installed on the second connecting rod 19. The clamping plate 20 is rotatably connected to the threaded end of the rotating rod 15 via a connecting ring 21. A grinding head is slidably connected to the clamping plate 20. 22. The staff places the billboard on the platform inside the grinding chamber 1. Using a vertical moving device, the billboard is positioned between two grinding heads 22, facilitating the grinding of its edges and corners. When the grinding head 22 needs replacement, the staff rotates the rotating rod 15. One end of the rotating rod 15 is threadedly connected to the support. When the staff manually rotates the rotating rod 15 clockwise, it causes the rotating rod 15 and its connected ring 151 to move laterally. The ring 151 has a first connecting rod 17 on each side, rotated via a first ball head 16. The first connecting rod 17... The second ball head 18 is rotatably connected to the second connecting rod 19, and the second connecting rod 19 is fixedly fitted with a retaining plate 20. This allows the first ball head 16 and the second ball head 18 to rotate when the ring 151 moves laterally, thereby changing the angle of the first connecting rod 17 and the second connecting rod 19. Furthermore, the first ball head 16 and the second ball head 18 are equipped with blocking devices, so that when the first ball head 16, the second ball head 18, the first connecting rod 17, and the second connecting rod 19 move, they cause the two retaining plates 20 to rotate towards the rotating rod 15, thus disengaging the retaining plates 20 from the grinding head 22, facilitating the replacement of the new grinding head. When the grinding head 22 needs to be installed, the operator puts the grinding head 22 onto the clamping plate 20, and then rotates the rotating rod 15 counterclockwise, causing it to drive the ring 151 to move laterally in the opposite direction, which in turn drives the first ball head 16, the second ball head 18, the first connecting rod 17, and the second connecting rod 19 to move in the opposite direction, thereby driving the two clamping plates 20 to rotate away from the rotating rod 15, so that the clamping plates 20 are inserted into the grinding head 22. After the grinding head 22 is installed, part of the rotating rod 15 is still outside the grinding head 22, which is convenient for the operator to rotate to control the opening and closing of the clamping plates 20.

[0029] like Figure 1 - Figure 6As shown, the inner wall of the grinding head 22 has corresponding sliding grooves 23 on both sides. The sliding grooves 23 are slidably connected to the clamping plate 20. Limiting blocks 161 are fixedly installed inside the first ball head 16 and the second ball head 18. An electric hydraulic push rod 2 is fixedly installed on the inner wall of the grinding chamber 1. An auxiliary plate 3 is fixedly installed on the upper end of the electric hydraulic push rod 2. A rotating plate 5 is set above the auxiliary plate 3. By setting the sliding grooves 23, when the clamping plate 20 rotates away from the rotating rod 15, the clamping plate 20 is engaged in the sliding grooves 23, so that the grinding head 22... 2. The connection is more stable. By fixing the limit block 161 in the first ball head 16 and the second ball head 18, the rotation angle of the first connecting rod 17 and the second connecting rod 19 is limited to avoid excessive rotation. By setting the electric hydraulic push rod 2, it can drive the auxiliary plate 3 fixedly installed on its upper end to rise when it extends, thereby driving the rotating plate 5 on which the billboard is placed to rise and fall, so that the billboard can be located between the two grinding heads 22 and the corners of the billboard extend beyond the rotating plate 5.

[0030] like Figure 1 - Figure 6 As shown, the output end of a first drive device 4 is fixedly installed on the lower surface of the rotating plate 5. The rotating plate 5 is used to place the billboard. A pressure plate 7 is set above the rotating plate 5. The pressure plate 7 is fixedly connected to the inner wall of the grinding chamber 1 through an electric push rod 6. Slide rails 8 are fixedly installed on the corresponding sides of the inner wall of the grinding chamber 1. Electric drive wheels 9 are slidably connected in the slide rails 8. One end of the electric drive wheel 9 is fixedly connected to the support connecting plate 10. By setting the first drive device 4 and fixing the output end of the first drive device 4 to the rotating plate 5, when the operator opens the first drive device 4, the rotating plate 5 is driven to rotate, thereby driving the billboard placed on it to rotate. The size of the grinding chamber 1 allows the billboard to rotate inside it. At the same time, a lifting platform is set at the lower end of the first drive device 4. A pressure plate 7 is provided, which is fixedly connected to the inner wall of the grinding chamber 1 via an electric push rod 6. Before the billboard is ground, the operator activates the electric push rod 6, which moves the pressure plate 7 toward the rotating plate 5. The pressure plate 7 then holds the billboard placed on the rotating plate 5 in place, preventing displacement during grinding. At the same time, the pressure plate 7 does not contact the billboard when it rotates. Slide rails 8 are fixedly installed on the corresponding sides of the inner wall of the grinding chamber 1, and electric drive wheels 9 are slidably connected in the slide rails 8. One end of the electric drive wheel 9 is fixedly connected to the support connecting plate 10. When the operator controls the electric drive wheel 9 to move in the slide rails 8, it drives the support connecting plate 10 and the grinding head 22 to move, so that the grinding head 22 can grind the corners of the pressed billboard.

[0031] like Figure 1 - Figure 6As shown, several telescopic rods 11 are fixedly installed on corresponding sides of the support connecting plate 10, and several springs 12 are fixedly installed on corresponding sides of the support connecting plate 10. The springs 12 are located outside the telescopic rods 11. A support plate 13 is fixedly installed at the end of the telescopic rod 11 away from the support connecting plate 10. A second drive device 141 is fixedly installed inside the support plate 13. The output end of the second drive device 141 is fixedly connected to the connecting plate 14. By connecting the support plates 13 to the springs 12 on the corresponding upper and lower sides of the support connecting plate 10 through the telescopic rods 11, when the billboard is thick, the staff can manually pull the two support plates 13 in opposite directions. At the same time, the elastic force of the springs 12 causes the support plates 13 to drive the two grinding heads 22 to clamp the billboard. This allows the grinding head 22 to simultaneously grind both sides of billboards of different thicknesses. When the billboard rotates, the operator can remove it from between the two grinding heads 22 to facilitate rotation. After rotation, the billboard is placed back between the two grinding heads 22 for grinding. A second drive device 141 is fixedly installed inside the support plate 13, and the output end of the second drive device 141 is fixedly connected to the connecting plate 14. When the operator turns on the second drive device 141, the connecting plate 14, which is fixedly connected to its output end, rotates, thereby driving the device set on the connecting plate 14 to rotate, and then the grinding head 22 rotates, resulting in a better grinding effect on the edges and corners of the billboard.

[0032] Working principle: The operator places the billboard on the rotating plate 5. By adjusting the angle of the electric hydraulic push rod 2 and the rotating plate 5, the edge to be polished is positioned between the two polishing heads 22. Simultaneously, when the billboard is thick, the operator manually pulls the two support plates 13 in opposite directions. The spring force of the spring 12 causes the support plates 13 to clamp the two polishing heads 22, allowing the polishing heads 22 to polish both sides of billboards of different thicknesses simultaneously. When the polishing head 22 needs to be replaced, the operator manually rotates the rotating rod 15 clockwise, causing the rotating rod 15 and its connected ring 151 to move laterally. This lateral movement of the ring 151 causes the first ball head 16 and the second ball head 18 to rotate, which in turn causes the first connecting rod 17 and the second connecting rod 18 to rotate. The angle of the rod 19 changes, and the first ball head 16 and the second ball head 18 are equipped with blocking devices. When the first ball head 16, the second ball head 18, the first connecting rod 17 and the second connecting rod 19 move, they drive the two clamping plates 20 to rotate towards the rotating rod 15, thereby causing the clamping plates 20 to leave the grinding head 22. This makes it easier for the operator to replace the grinding head 22. When the grinding head 22 needs to be installed, the operator puts the grinding head 22 on the clamping plate 20, and then rotates the rotating rod 15 counterclockwise, causing it to drive the ring 151 to move laterally in the opposite direction. This, in turn, causes the first ball head 16, the second ball head 18, the first connecting rod 17 and the second connecting rod 19 to move in the opposite direction, which in turn causes the two clamping plates 20 to rotate away from the rotating rod 15, thereby causing the clamping plates 20 to engage inside the grinding head 22.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
