When the silo feeds material into the adjusting tube, it enters the diamond-shaped bucket through the adjusting tube, and a plurality of fan-shaped plates are arranged in the diamond-shaped bucket to form an umbrella shape. After the material falls on the outer wall of the fan-shaped plate, it will bounce toward the inner wall of the top of the diamond-shaped bucket.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] First embodiment:

[0020] See also Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of the automatic blanking equipment for light guide plate production. Figure 2 It is a schematic diagram of the structure of the blanking assembly. Figure 3 It is a schematic diagram of the installation structure of a rotating motor.

[0021] The utility model provides an automatic blanking equipment for light guide plate production, including a silo 101, a discharge port 102 and a blanking assembly 103, the blanking assembly 103 includes a mounting shell 104, a rotating motor 105, a driving rod 106, a lifting plate 107, a rotating rod 108, a dividing cone 109 and a driving member 110, the dividing cone 109 includes a cone 111 and a plate 112, the driving rod 106 has a limiting protrusion 113, the rotating rod 108 has a limiting groove 114, the driving rod 106 is driven to rotate by the rotating motor 105, and then the rotating rod 108 and the dividing cone 109 are driven to rotate, so as to avoid the blockage of the raw material at the dividing cone 109 and further improve the uniformity of the blanking. It can be understood that the above scheme can be used to avoid the problem of blockage of the raw material during blanking, and can also be used to solve the problem of driving the lifting plate 107 to lift.

[0022] According to this specific embodiment, the discharge port 102 is installed on the silo 101 , the discharge port 102 is communicated with the silo 101 , and the discharge port 102 is communicated with the feed port of an extruder (not shown in the figure) below.

[0023] Among them, the mounting shell 104 is fixedly connected to the discharge port 102 and is located inside the discharge port 102, the rotating motor 105 is connected to the mounting shell 104 and is located inside the mounting shell 104, the driving rod 106 is arranged on the rotating motor 105 and is connected to the output end of the rotating motor 105, the lifting plate 107 is slidably connected to the mounting shell 104 and is located inside the mounting shell 104, the rotating rod 108 is slidably connected to the driving rod 106 and is rotatably connected to the lifting plate 107 and is sleeved on the driving rod 106, the dividing cone 109 is fixedly connected to the rotating rod 108 and is located at one end of the rotating rod 108, and the driving component 110 is arranged on the mounting shell 104; the driving component 110 can drive the lifting plate 107 to rise and fall, and when in use, the raw materials inside the silo 101 fall into the discharge port 102, and then the raw materials pass through the dividing cone 109 and the discharge port. The raw materials are discharged through the gap between the outlet 102, and the raw materials can be discharged evenly through the dividing cone 109. The lifting plate 107 is driven to rise and fall by the driving component 110, and then the rotating rod 108 and the dividing cone 109 are driven to rise and fall, so that the distance between the dividing cone 109 and the inner wall of the discharge port 102 can be adjusted, thereby adjusting the material dropping speed; during the material dropping process, the rotating motor 105 is started to drive the driving rod 106 to rotate, and then the rotating rod 108 and the dividing cone 109 are driven to rotate. The rotation of the dividing cone 109 avoids the blockage of the raw materials. At the same time, the rotation of the dividing cone 109 makes the raw materials evenly scattered around, thereby further improving the uniformity of the material dropping. The sliding connection between the driving rod 106 and the rotating rod 108 ensures that the driving rod 106 does not interfere with the lifting and lowering of the rotating rod 108, thereby avoiding interfering with the lifting and lowering of the dividing cone 109, thereby avoiding the blockage of the raw materials during the material dropping and affecting the material dropping.

[0024] Secondly, the cone 111 is fixedly connected to the rotating rod 108 and is located at one end of the rotating rod 108; the plate 112 is fixedly connected to the cone 111 and is arranged on the cone 111; there are multiple plates 112, which are evenly distributed on the cone 111. When the cone 111 rotates, it will drive multiple plates 112 to rotate, so that the plates 112 can stir the raw materials, thereby further avoiding blockage of the raw materials.

[0025] At the same time, the limiting protrusion 113 is arranged on the driving rod 106 and is located on one side of the driving rod 106; the limiting groove 114 is arranged on the rotating rod 108 and is located on the side of the rotating rod 108 close to the limiting protrusion 113, and the limiting groove 114 cooperates with the limiting protrusion 113; the limiting protrusion 113 is located inside the limiting groove 114, and the rotating rod 108 is limited by the limiting protrusion 113, so that only vertical movement can occur between the rotating rod 108 and the driving rod 106, thereby avoiding slipping between the driving rod 106 and the rotating rod 108.

[0026] When the automatic blanking equipment for producing light guide plates of this embodiment is used, the raw materials inside the silo 101 fall into the feed port, and the raw materials fall more evenly through the dividing cone 109. At the same time, the driving rod 106 and the rotating rod 108 are driven to rotate by the rotating motor 105, so that the rotating rod 108 drives the dividing cone 109 to rotate, and the dividing cone 109 rotates during the falling process of the raw materials, thereby avoiding blockage of the raw materials.

[0027] Second embodiment:

[0028] Based on the first embodiment, please refer to Figure 4 , Figure 4 2 is a schematic diagram of the structure of the driving member of the second embodiment. The driving member 110 of this embodiment includes a threaded rod 201, a guide rod 202 and a rotating component 203. The rotating component 203 includes a worm wheel 204, a worm 205 and a connecting rod 206.

[0029] According to this specific embodiment, the threaded rod 201 is rotatably connected to the mounting shell 104, and is threadedly connected to the lifting plate 107, and is located inside the mounting shell 104; the guide rod 202 is fixedly connected to the mounting shell 104, and is slidably connected to the lifting plate 107, and is located inside the mounting shell 104; the rotating component 203 is arranged on the mounting shell 104, and drives the threaded rod 201 to rotate; the lifting and lowering of the lifting plate 107 is guided by the guide rod 202 to improve the stability of the lifting plate 107 during lifting and lowering, and the threaded rod 201 is driven to rotate by the rotating component 203. Since the lifting plate 107 is threadedly connected to the threaded rod 201, the rotation of the threaded rod 201 can drive the lifting plate 107 to be lifted and lowered.

[0030] Among them, the worm wheel 204 is fixedly connected to the threaded rod 201 and is located at one end of the threaded rod 201; the worm 205 is rotatably connected to the mounting shell 104, meshes with the worm wheel 204, and is located inside the mounting shell 104; the connecting rod 206 is fixedly connected to the worm 205, rotatably connected to the discharge port 102, and is arranged on the discharge port 102; a knob is provided at one end of the connecting rod 206, and the worm 205 is driven to rotate by rotating the connecting rod 206, so that the worm 205 drives the worm wheel 204 to rotate, and then drives the threaded rod 201 to rotate, thereby achieving the purpose of driving the threaded rod 201 to rotate, and at the same time, through the self-locking property between the worm wheel 204 and the worm 205, the worm wheel 204 cannot drive the worm 205 to rotate, thereby improving the stability of the threaded rod 201.
