When the support block moves with the conveyor belt until it abuts against the baffle, the baffle is squeezed and moves up into the accommodating groove, and compresses the elastic member, so that the material chamber discharge port is opened.

A top plate 601 is arranged inside the above-mentioned loading box 6, and an electric telescopic column 602 is arranged between the top plate 601 and the bottom wall of the loading box 6.

[0030] A first motor 2011 for driving the conveyor belt 201 is mounted on the outer wall of one of the support plates 207 .

[0031] An avoidance groove 210 is formed at one end of the support plate 207 close to the workbench 1 .

[0032] A second motor 101 for driving the turntable 103 to rotate is disposed inside the workbench 1 .

[0033] The turntable 103 is rotatably connected to the workbench 1 via a connecting shaft 102 , and the connecting shaft 102 is fixedly connected to the output shaft of the second motor 101 .

[0034] Embodiment 2: An optical-grade PMMA plate production and transportation device, comprising: a workbench 1, a turntable 103 having a plurality of connecting rods 104 on a circumferential side wall is rotatably mounted at the central position of the workbench 1, and a material loading box 6 is mounted at one end of the connecting rod 104 away from the turntable 103;

[0036] A body 2 with a bearing area is disposed on one side of the workbench 1, and a material cavity 204 with a feed port 208 at the top is disposed at the end of the body 2 away from the workbench 1, and a discharge port 206 is disposed at the bottom of the side wall of the material cavity 204, and the bottom inner wall of the material cavity 204 is inclined so that the light guide plate can slide out of the discharge port 206 under the action of gravity;

[0038] The materials in the loading box are pushed up by the electric telescopic column, and the materials are pushed down to the unloading platform by the L-shaped fixed frame during the rotation of the loading box, so that the materials can be unloaded automatically, which further reduces the labor intensity of the personnel and is conducive to improving the continuity of the production process of optical grade PMMA plates;

[0039] A support 3 with a material unloading platform 4 installed on the top is arranged on the other side of the workbench 1, and an L-shaped fixing frame 5 is installed on the top of the material unloading platform 4. A top plate 601 is arranged inside the material loading box 6, and an electric telescopic column 602 is arranged between the top plate 601 and the bottom wall of the material loading box 6;

[0040] After the light guide plate enters the loading box, the second motor is started to drive the connecting shaft to rotate, thereby driving the turntable to rotate, and then driving the loading box to rotate through the connecting rod, so that the light guide plate in the loading box can move. When the loading box is transferred close to the support, the electric telescopic column is controlled to push the top plate up, thereby moving the light guide plate to be processed up and out of the loading port range. As the loading box continues to move, the light guide plate will fall onto the unloading table under the obstruction of the L-shaped fixed frame, and will be unloaded in an orderly manner along the unloading table.

[0041] A first motor 2011 for driving the conveyor belt 201 is mounted on the outer wall of one of the support plates 207 .

[0042] An avoidance groove 210 is formed at one end of the support plate 207 close to the workbench 1 .

[0046] The support block 205 is located on one side of the surface of the conveyor belt 201 close to the support plate 207 .

[0047] The working principle is:

[0048] When in use, the light guide plates to be processed are stacked and placed in order in the material chamber. When working, the first motor is started to drive the conveyor belt for transmission. When the support block moves with the conveyor belt until it abuts against the baffle, the baffle is squeezed and moves up into the accommodating groove, and compresses the elastic member, so that the material chamber discharge port is opened. At this time, the light guide plates to be processed at the bottom layer in the material chamber will automatically slide out of the material chamber discharge port and be transmitted on the conveyor belt until they fall into the material loading box at the front position. As the light guide plates and the support block move away from the baffle, the baffle will also be reset under the elastic force of the elastic member, and the material chamber discharge port will be blocked again.

[0049] After the light guide plate enters the loading box, the second motor is started to drive the connecting shaft to rotate, thereby driving the turntable to rotate, and then driving the loading box to rotate through the connecting rod, so that the light guide plate in the loading box can move. When the loading box is transferred close to the support, the electric telescopic column is controlled to push the top plate up, thereby moving the light guide plate to be processed up and out of the loading port range. As the loading box continues to move, the light guide plate will fall onto the unloading table under the obstruction of the L-shaped fixed frame, and will be unloaded in an orderly manner along the unloading table.

[0050] When the above optical-grade PMMA plate production and transportation equipment is used, the support block on the conveyor belt lifts the baffle through the cyclic rotation of the conveyor belt, so that the discharge port is opened and closed regularly, which reduces the labor intensity of personnel, realizes the automatic loading of the optical-grade PMMA plate, improves the continuity of the processing process, and improves the overall processing efficiency;

[0051] In addition, the material inside the loading box is pushed up by an electric telescopic column, and during the rotation of the loading box, the material is pushed down to the unloading table by the L-shaped fixed frame, thereby realizing automatic unloading of the material, further reducing the labor intensity of the personnel, and is conducive to improving the continuity of the production process of optical-grade PMMA boards.
