DETAILED DESCRIPTION

[0016] The following is a detailed description of the specific implementation of the present invention with reference to the accompanying drawings.

[0017] Example:

[0018] The following is a specific embodiment of the extruder feeding mechanism of the present invention, Figure 1 It mainly includes an upper hopper 1 arranged on the top of the extruder, a mounting plate 2 is provided on one side of the upper hopper 1, and three runners 3 are provided on the mounting plate 2. The three runners 3 are arranged in an inverted triangle, and any one of the runners 3 is driven to rotate by a motor.

[0019] A conveyor belt 4 is provided on the mounting plate 2 and is arranged around each rotating wheel 3. The conveyor belt 4 forms three inclined sections to facilitate material discharge.

[0020] A material box 6 is connected to the conveyor belt 4, and the material box 6 is connected to the conveyor belt 4 by two connecting blocks 5. However, it is not limited thereto, and multiple material boxes 6 can also be connected to the conveyor belt 4 at the same time to improve the conveying efficiency of the material.

[0021] Reference Figure 2 、 Figure 3 The specific structure of the magazine 6 is as follows: the interior of the magazine 6 is hollow, with one side open. A slot is defined at the top of the magazine 6, into which a switch door 7 is inserted. The switch door 7 is inserted into the interior of the magazine 6, sealing the opening on one side of the magazine 6. The top of the switch door 7 is higher than the top of the magazine 6. A touch plate 8 is connected to the top of the switch door 7. The bottom of the switch door 7 is in contact with the bottom wall of the magazine 6. Two limiting guide posts 9 are connected to the bottom of the magazine 6. The limiting guide posts 9 extend through the bottom of the magazine 6. Each limiting guide post 9 is sheathed with a spring 10, which abuts against the bottom of the magazine 6. A positioning plate 11 is also connected to the switch door 7 between the touch plate 8 and the magazine 6. The spring 10 acts to keep the positioning plate 11 in contact with the magazine 6.

[0022] Reference Figure 1 A cylinder 12 is provided on the mounting plate 2 on one side of the conveyor belt 4. The output shaft of the cylinder 12 is connected to a first connecting rod 13, which is connected to a telescopic plate 14. The first connecting rod 13 is also connected to a second connecting rod 15, which is connected to a guide plate 16. The guide plate 16 is provided below the material box 6. A feed port 1a is provided at the top of the upper hopper 1. The guide plate 16 is arranged inclined towards the feed port 1a, and a barrier 17 is provided on the feed port 1a.

[0023] When the present invention is working, the motor drives the wheel 3 to rotate, the wheel 3 drives the conveyor belt 4 to operate, and the conveyor belt 4 drives the material box 6 to move. When loading is needed, the material box 6 is moved to the feeding port 1a of the upper hopper 1, and the cylinder 12 extends, driving the first connecting rod 13 and the telescopic plate 14 to extend. The telescopic plate 14 extends to the inside of the touch plate 8 of the material box 6, and the conveyor belt 4 drives the material box 6 to continue to move downward for a distance, and the switch door 7 opens. At the same time, the second connecting rod 15 also drives the guide plate 16 to extend, and the guide plate 16 extends to the bottom of the material box 6. The material in the inclined material box 6 falls into the upper hopper 1 through the feeding port 1a. The guide plate 16 can guide the material and also prevent the material from falling and polluting the working environment. The enclosure 17 on the feeding port 1a can ensure that the material falls into the feeding port 1a accurately. After loading is completed, the cylinder 12 drives the telescopic plate 14 and the guide plate 16 to retract. With the cooperation of the spring 10 and the positioning plate 11, the switch door 7 is automatically closed, and the conveyor belt 4 can drive the material box 6 to continue to move downward. The material box 6 does not interfere with the upper hopper 1 and the feed port 1a.
