The second cylinder is mounted vertically on the top of the moving block; A movable frame, which has a frame structure, is fixedly connected to the top of the piston rod of the second cylinder so as to be driven by the second cylinder to move up and down in the vertical direction; A limiting device is provided inside the movable frame to limit and fix the plate within the movable frame, and to allow the side of the plate to be polished to extend out of the movable frame. The limiting device includes a sliding plate and a support block. Connecting grooves are provided on both side walls of the movable frame in the horizontal direction. The sliding plate is slidably embedded in the inner wall of the connecting groove. The support block is fixedly connected to the outer wall of the movable frame and is provided corresponding to the connecting groove.

[0011] Preferably, the thread direction on the surface of the threaded rod is set in opposite directions from the middle to both ends, so that when the threaded rod rotates around its own axis, it drives the sliding plates on both sides to slide synchronously relative to each other or in opposite directions along the inner wall of the connecting groove.

[0012] Preferably, the limiting device further includes a sliding frame, which is a hollow frame and is slidably fitted onto one end of the sliding plate near the inner wall of the moving frame in a direction close to / away from the center of the moving frame; when the plate moves towards the polishing roller, the sliding frame can be pushed to slide away from the sliding plate to accommodate the need for plates of different thicknesses to extend beyond the moving frame.

The first damping rod is fixedly connected to the inner wall of the sliding frame away from the center of the moving frame along the sliding direction of the sliding frame, and the telescopic end of the first damping rod is fixedly connected to one end of the sliding plate that extends into the sliding frame. The first spring is coaxially sleeved on the outer peripheral surface of the first damping rod, and one end of the first spring is fixedly connected to one side of the inner wall of the sliding frame, and the other end is fixedly connected to one end of the sliding plate, so that the sliding frame is pulled towards the sliding plate by the elastic force of the first spring, so that the sliding frame is limited to fit against the surface of the sliding plate.

[0014] Preferably, the limiting device further includes a rubber plate, which is sheet-shaped and fixedly connected to the side of the sliding frame near the inner wall of the moving frame, and is in contact with the side wall of the plate; when the sliding frame squeezes the plate, the rubber plate prevents the plate from sliding along the side wall of the sliding frame through its own friction.

[0022] Example 1, as Figure 1-5 As shown, a plate polishing device includes a connecting box 1 with a support plate 2 fixedly connected to the top. A motor 3 is installed on the top of the support plate 2, and a polishing roller 4 is rotatably inserted into one side of the support plate 2. The motor 3 and the polishing roller 4 are connected together by bearings. A sliding groove 5 is provided on the top of the connecting box 1. A first cylinder 7 is installed on one side of the inner wall of the sliding groove 5. A moving block 6 is provided at one end of the first cylinder 7 near the inner wall of the sliding groove 5. A second cylinder 8 is installed on the top of the moving block 6. A moving frame 10 is installed on the top of the second cylinder 8. A limit device 9 is provided on one side of the moving frame 10. When using the polishing device, the plate is placed on one side of the moving frame 10, and then the motor 3 drives the polishing roller 4 to rotate. Then, the first cylinder 7 and the second cylinder 8 drive the plate closer to the polishing roller 4, thus polishing the surface of the plate.

[0023] Reference Figures 2 to 4The limiting device 9 includes a sliding plate 902. A connecting groove 901 is provided on one side of the moving frame 10. The inner wall of the connecting groove 901 is slidably connected to the sliding plate 902. A support block 903 is fixedly connected to one side of the moving frame 10. When using the limiting device 9, the two sliding plates 902 are controlled to slide relative to each other on the inner wall of the connecting groove 901. Because the thickness of the plate is greater than the thickness of the inner wall of the moving frame 10, the plate can be placed inside the moving frame 10, and the side that needs to be polished can be placed on the outside of the moving frame 10. A threaded rod 904 is rotatably inserted into one side of the support block 903. The threaded rod 904 is threaded through and inserted into one side of the sliding plate 902. The thread direction on the surface of the threaded rod 904 is opposite from the middle to both sides. The threaded rod is manually controlled. Rotating 904 facilitates simultaneous control of the relative sliding of two sliding plates 902. A sliding frame 910 is slidably fitted onto one end of the sliding plate 902 near the inner wall of the moving frame 10, controlling the material to move closer to the polishing roller 4, thereby causing the sliding frame 910 to move away from the sliding plate 902. This allows materials of different thicknesses to be easily placed outside the moving frame 10. A first damping rod 912 is fixedly connected to one side of the inner wall of the sliding frame 910. One end of the first damping rod 912 near the sliding plate 902 is fixedly connected to one end of the sliding plate 902. A first spring 913 is fitted onto the surface of the first damping rod 912. One end of the first spring 913 is fixedly connected to one side of the inner wall of the sliding frame 910. The first spring 913 near the sliding plate 902... One end of the sliding frame 910 is fixedly connected to the sliding plate 902. A first spring 913 pulls the sliding frame 910 towards the sliding plate 902, thus confining the sliding frame 910 to the surface of the sliding plate 902. Rubber plates 911 are fixedly connected to the side of each sliding frame 910 near the inner wall of the moving frame 10. When the sliding frame 910 is pressed against one side of the plate, the rubber plates 911 press against one side of the sliding frame 910, preventing the plate from sliding on one side of the sliding frame 910. A bolt 908 is threaded through one side of the moving frame 10. The bolt 908 is located on one side of the plate. Manually controlling the rotation of the bolt 908 presses it against one side of the plate, thus controlling the plate away from the interior of the moving frame 10. A rotating plate 909 is rotatably fitted at one end of the bolt 908 near the inner wall of the movable frame 10. When the bolt 908 is pressed against one side of the plate, the rotating plate 909 is also pressed against one side of the plate, which increases the contact area between the bolt 908 and the plate, thus facilitating the bolt 908 to press the plate effectively. A second damping rod 905 is fixedly connected to the top of the movable frame 10, and a pressing plate 907 is fixedly connected to the top of the second damping rod 905. A second spring 906 is fitted on the surface of the second damping rod 905. One end of the second spring 906 is fixedly connected to the top of the movable frame 10, and the end of the second spring 906 near the pressing plate 907 is fixedly connected to the bottom of the pressing plate 907. The pressing plate 907 is pulled towards the movable frame 10 by the second spring 906.This causes the extrusion plate 907 to press against the top of the sheet material, thus confining the sheet material within the moving frame 10.

[0024] To address the technical problem that unstable connection between the connecting box and the work platform during the polishing process can affect production quality, an adsorption structure is provided on the lower surface of the connecting box.

[0025] In one embodiment, the adsorption structure includes a connecting rod and an adsorption section. One end of the connecting rod is connected to the lower surface of the connecting box, and the other end of the connecting rod is connected to the adsorption section, which is used to adsorb the working platform.

[0026] The adsorption part is made of a soft material such as silica gel or rubber.

[0027] Each of the connecting boxes has four adsorption structures on its lower surface.

[0028] In order to enable the adsorption structure to rise and fall to adapt to various working conditions, the connecting rod includes a first telescopic part, a second telescopic part partially housed within the first telescopic part, and a stable connecting part disposed at one end of the second telescopic part and housed within the first telescopic part. The outer diameter of the first telescopic part sleeved at one end of the second telescopic part is smaller than the outer diameter of the end where the first telescopic part and the adsorption part are connected. The outer diameter of the second telescopic part partially housed at one end of the first telescopic part is smaller than the outer diameter of the second telescopic part connected to the limiting plate.

[0029] The outer surface of the first telescopic part, which is sleeved on one end of the second telescopic part, has multiple through holes that penetrate the outer surface of the second telescopic part. The through holes are evenly distributed along the axial direction of the first telescopic part. At this time, a locking pin is provided in one of the through holes on the first telescopic part. When the second telescopic part is slid, one of the through holes on the first telescopic part can correspond to one of the through holes on the second telescopic part, so that the locking pin can extend from one of the through holes on the first telescopic part to one of the through holes on the second telescopic part, thereby keeping the first telescopic part and the second telescopic part relatively fixed and improving the connection stability of the first telescopic part and the second telescopic part.

[0030] In one embodiment, the stabilizing connection is made of rubber material. Understandably, in other embodiments not shown, the stabilizing connection may also be made of materials such as silicone. By sliding the second telescopic part, the stabilizing connection can gradually abut against the inner surface of the first telescopic part.

[0031] In one embodiment, the outer surface of the abutment is provided with anti-slip textures, the textures of which are interlaced.

[0032] In one embodiment, the surface of the first telescopic part is provided with an aluminum alloy coating, the thickness of which is 0.1-0.3 mm.

[0033] In one embodiment, the surface of the second telescopic part is provided with a titanium alloy coating, the thickness of which is 0.2-0.5 mm.

[0034] The plate polishing device of the present invention can improve the connection stability between the connecting box and the working platform and improve the production quality. On the other hand, the adsorption structure can be raised and lowered to adapt to various different working conditions.

[0035] Working principle: When using the polishing device, the material is placed on one side of the moving frame 10. The motor 3 drives the polishing roller 4 to rotate, and the first cylinder 7 and the second cylinder 8 move the material closer to the polishing roller 4, thus polishing the surface of the material. When using the limiting device 9, the threaded rod 904 is manually controlled to rotate, facilitating simultaneous control of the relative sliding of the two sliding plates 902. This causes the sliding frame 910 to press against one side of the material. When the sliding frame 910 presses against one side of the material, the rubber plate 911 presses against one side of the sliding frame 910, preventing the material from sliding on one side of the sliding frame 910, because the thickness of the material is greater than... The thickness of the inner wall of the movable frame 10 allows the plate to be placed inside the movable frame 10. The bolt 908 is manually rotated, causing it to press against one side of the plate. When the bolt 908 is pressed against one side of the plate, the rotating plate 909 is also pressed against one side of the plate. This increases the contact area between the bolt 908 and the plate, making it easier for the bolt 908 to press against the plate effectively. The second spring 906 pulls the pressing plate 907 towards the movable frame 10, causing it to press against the top of the plate. This helps to control the plate away from the inside of the movable frame 10, allowing the side that needs to be polished to be placed on the outside of the movable frame 10.

[0036] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process, and the polishing device is the commonly used UNIPOL-830.
