[0002] During the drying process of gypsum boards, warping, unevenness or tiny cracks may occur due to uneven drying positions, etc. Generally, grinding is used to eliminate these defects, making the surface smoother and flatter. Moreover, these dimensional changes can also be corrected to ensure neat joints after installation and improve the overall decoration effect.

[0003] In the prior art, gypsum boards are generally placed on a conveyor belt, and both sides of the gypsum board are ground by a grinding device, which can be a hand-held grinding tool or a robot for grinding. However, when grinding the other side, in both of these grinding methods, the gypsum board needs to be manually turned over before continuing the grinding operation. The manual turning method requires at least two workers to cooperate for turning over. The manual turning method not only has low efficiency, but also the gypsum board is easily bumped during the turning process. Summary of the Utility Model

One side of the turnover plate is connected to the rotating shaft. The turnover plate can be placed on the first annular groove, and a limiting frame body capable of passing through the gypsum board is arranged along the axis direction on the side far from the rotating shaft;

[0009] The second conveyor roller group includes a plurality of second rotating rollers arranged at intervals in the horizontal direction. The second rotating rollers are provided with second annular grooves along their circumferential directions. The horizontal plane where the highest position of the second annular groove is located is lower than the horizontal plane where the highest position of the first annular groove is located.

[0010] The conveying direction of the roller conveyor belt is to transport the gypsum board from the first conveying roller group to the second conveying roller group. The gypsum board can move through the first rotating roller. When the gypsum board passes through the limiting frame and moves close to the rotating shaft, the turning plate is located below the gypsum board. By controlling the rotating shaft, the gypsum board can be rotated upward with the side close to the rotating shaft as the rotation axis. Under the limitation of the limiting frame, the gypsum board will not break away from the turning plate. When it is turned to the second rotating roller, the turning plate is located on the second annular groove to achieve storage, without affecting the transportation of the gypsum board through the second rotating roller, and drives the gypsum board to move out of the turning plate and the limiting frame for grinding on the other side.

[0011] To ensure that the turning plate does not affect the movement of the gypsum board on the first rotating roller and can also drive the gypsum board to turn through rotation, when the turning plate is arranged on the outer circular surface of the first annular groove, the height of the horizontal plane where its upper surface is located is lower than the height of the horizontal plane where the highest position of the first rotating roller is located.

[0012] Regarding the specific structure of the limiting frame, to facilitate the gypsum board to pass through the limiting frame when moving from the first rotating roller and be located above the turning plate, the vertical distance between the upper surface of the inner side of the limiting frame and the horizontal plane where the highest position of the first rotating roller is located is greater than the thickness of the gypsum board by 1 - 5 cm, and the lower surface of the inner side of the limiting frame is lower than the upper surface of the turning plate.

[0014] To facilitate the storage of the turned - over turning plate in the second annular groove and facilitate the smoothly conveying of the turned - over gypsum board through the second rotating roller out of the turning mechanism for grinding on the other side, the vertical distance between the horizontal plane where the highest position of the second annular groove is located and the horizontal plane where the highest position of the first annular groove is located is not less than the thickness of the gypsum board.

To facilitate buffering the gypsum board after flipping, a buffer plate is provided on the upper surface inside the limiting frame body. The buffer plate is connected to the limiting frame body through an elastic member. The length direction of the buffer plate is the same as the length direction of the limiting frame body. The vertical distance between the horizontal plane where the lower surface of the buffer plate is located in the initial state and the horizontal plane where the highest position of the first rotating roller is located is greater than the thickness of the gypsum board, facilitating the smooth passage of the gypsum board through the limiting frame body with the buffer plate.

[0018] To facilitate the limitation of the gypsum board on the side close to the rotating shaft, a plurality of limiting frame bodies are arranged along the length direction of the flipping plate.

[0019] The beneficial effects of the present utility model are as follows:

[0020] By providing a flipping mechanism, the gypsum board can be flipped from a plurality of first rotating rollers to the second rotating rollers. The flipping plate is in the first rotating groove of the first rotating roller and will not affect the conveyance of the gypsum board on the first rotating roller. The flipping plate is arranged on the outer side surface of the first rotating groove, and the rotating first rotating roller is in sliding connection with the flipping plate without driving the flipping plate to move. The gypsum board can be flipped under the drive of the flipping plate and the fiber frame body. The flipping plate drives the gypsum board to flip to a plurality of second rotating rollers on the other side. The flipping plate is received in a plurality of second annular grooves, enabling one side of the gypsum board to directly contact a plurality of second rotating rollers. The gypsum board can slide out of the limiting frame body under the drive of a plurality of rotating rollers to achieve flipping and proceed to the next step of grinding. Compared with the manual flipping in the prior art, it can greatly improve the grinding efficiency of the gypsum board and will not cause the phenomenon of damaging the gypsum board due to collision.

[0021] To facilitate buffering the gypsum board after flipping, a buffer plate is provided on the upper surface inside the limiting frame body. The buffer plate is connected to the limiting frame body through an elastic member. The length direction of the buffer plate is the same as the length direction of the limiting frame body.

[0030] Refer to Figure 1 and Figure 2 As shown, a flipping device for grinding gypsum boards is arranged on the roller conveyor belt 1 for conveying gypsum boards. The roller conveyor belt 1 includes a frame body 101 and a first conveyor roller group, a flipping mechanism, and a second conveyor roller group arranged in sequence along the length direction of the frame body 101. The conveying direction of the roller conveyor belt 1 is to convey gypsum boards from the first conveyor roller group to the second conveyor roller group.

[0031] Refer to Figure 3 As shown, the first conveyor roller group includes a plurality of first rotating rollers 2 arranged at intervals in the horizontal direction, and the second conveyor roller group includes a plurality of second rotating rollers 3 arranged at intervals in the horizontal direction. The plurality of first rotating rollers 2 and the plurality of second rotating rollers 3 are arranged along the length direction of the frame body 101, and the axes of the first rotating rollers 2 and the second rotating rollers 3 are located in the same horizontal plane. The roller conveyor belt 1 further includes a belt transmission system. The belt of the belt conveyor system 102 can connect each first rotating roller 2 and the second rotating roller 3 and can drive the first rotating roller 2 and the second rotating roller 3 to rotate simultaneously. The synchronous rotation of the first rotating roller 2 and the second rotating roller 3 is prior art.

[0032] Among them, a first annular groove 201 is formed along the circumferential direction of the first rotating roller 2; a second annular groove 301 is formed along the circumferential direction of the second rotating roller 3, and the horizontal plane where the highest position of the second annular groove 301 is located is lower than the horizontal plane where the highest position of the first annular groove 201 is located. Regarding the setting positions of the first annular groove 201 and the second annular groove 301, the length of the first annular groove 201 is greater than 1 / 3 of the length of the first rotating roller 2; the length of the second annular groove 301 is greater than 1 / 3 of the length of the second rotating roller 3, and the first annular groove 201 and the second annular groove 301 are arranged corresponding to each other. To facilitate the storage of the flipped flipping plate 5 in the second annular groove 301 and to facilitate the smooth conveyance of the flipped gypsum board through the second rotating roller 3 out of the flipping mechanism for grinding on the other side, the vertical distance between the horizontal plane where the highest position of the second annular groove 301 is located and the horizontal plane where the highest position of the first annular groove 201 is located is not less than the thickness of the gypsum board.

[0033] See Figure 1 and Figure 4 As shown, the flipping mechanism includes a rotating shaft 4, a flipping plate 5, and a driving motor 6 connected to the rotating shaft 4. The driving motor 6 is a reduction motor that can drive the rotating shaft 4 to rotate slowly, avoiding damage to the gypsum board on the flipping plate 5. The axis of the rotating shaft 4 is parallel to that of the first rotating roller 2, and both ends thereof are rotatably connected to the frame body 101. One side of the flipping plate 5 is connected to the rotating shaft 4. The flipping plate 5 can be placed on a plurality of first annular grooves 201, and a limiting frame body 7 capable of passing through the gypsum board is provided on the side away from the rotating shaft 4 along its axis direction. To facilitate the limitation of the gypsum board on the side close to the rotating shaft 4, a plurality of limiting frame bodies 7 are arranged along the length direction of the flipping plate 5, and one side of the gypsum board is bound to contact the outer surface of the rotating shaft 4. For this reason, an anti-slip sleeve 401 is sleeved on the outer surface of the rotating shaft 4 to increase the friction between one side of the gypsum board and the rotating shaft 4 and avoid the sliding of the gypsum board; and a positioning slot adapted to one side edge of the gypsum board can also be formed in the rotating shaft 4 along its axis direction, and one side of the gypsum board can be inserted into the positioning slot to prevent the gypsum board from detaching from the flipping plate 5.

[0034] To facilitate the installation of the flipping plate 5 on the rotating shaft 4, the lower surface of the flipping plate 5 is located on the outer surface of the first annular groove 201, and the horizontal plane of the height of its upper surface is lower than the horizontal plane of the highest height of the outer surface of the first rotating roller 2. To facilitate the rotating shaft 4 to drive the flipping plate 5 to flip a certain angle during rotation, the axis of the rotating shaft 4 is higher than the axis of the first rotating roller 2, and the length direction of the flipping plate 5 is arranged along the diameter direction of the first rotating roller 2.

[0035] To reduce the overall weight of the flipping plate 5, an opening 501 is provided in the middle of the flipping plate 5, and the length direction of the opening 501 is the same as the length direction of the flipping plate 5. To ensure that the flipping plate 5 does not affect the movement of the gypsum board on the first rotating roller 2 and can also drive the gypsum board to flip through rotation, when the flipping plate 5 is placed on the outer circular surface of the first annular groove 201, the height of the horizontal plane of its upper surface is lower than the height of the horizontal plane of the highest position of the first rotating roller 2.

[0036] The gypsum board can be moved through the first rotating roller 2. When the gypsum board passes through the limiting frame body 7 and moves close to the rotating shaft 4, at this time, the flipping plate 5 is located below the gypsum board. By controlling the driving motor 6 to drive the rotating shaft 4, the gypsum board can be rotated upward with one side edge close to the rotating shaft 4 as the rotation axis. Under the limitation of the limiting frame body 7, the gypsum board will not detach from the flipping plate 5. When it is flipped to the second rotating roller 3, the flipping plate 5 is placed on a plurality of second annular grooves 301 for storage, which does not affect the transportation of the gypsum board through the second rotating roller 3, and drives the gypsum board to move out of the flipping plate 5 and the limiting frame body 7 so that the other side can be polished manually or by a polishing robot 10.

[0037] SeeFigure 1 , Figure 4 and Figure 5 As shown in Figure 1 , Figure 4 and Figure 5 , for the specific structure of the limit frame body 7, in order to facilitate the gypsum board to pass through the limit frame body 7 when moving from the first rotating roller 2 and be located above the turning plate 5, the vertical distance between the upper surface of the inner side of the limit frame body 7 and the horizontal plane where the highest position of the first rotating roller 2 is located is greater than the thickness of the gypsum board by 1-5 cm, and the lower surface of the inner side of the limit frame body 7 is lower than the upper surface of the turning plate 5.

[0038] The distance inside the limit frame body 7 is greater than the thickness of the gypsum board. In order to facilitate buffering of the gypsum board after turning, a buffer plate 8 is provided on the upper surface of the inner side of the limit frame body 7. The buffer plate 8 is connected to the limit frame body 7 through an elastic member 9. The elastic member 9 is a compression spring and plays a reset role. The length direction of the buffer plate 8 is the same as the length direction of the limit frame body 7. The vertical distance between the horizontal plane where the lower surface of the buffer plate 8 is located in the initial state and the horizontal plane where the highest position of the first rotating roller 2 is located is greater than the thickness of the gypsum board, which is convenient for the gypsum board to smoothly pass through the limit frame body 7 with the buffer plate 8 inside.
