[0017] In order to make the purpose, technical scheme and advantage of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application, the technical scheme in the embodiments of the present application is clearly and completely described, obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0022] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] like Figure 1As shown, an automatic control device for a feeder includes a pipeline conveying assembly 1, a transport assembly 2, a controller 3, and a detector 4. The pipeline conveying assembly 1 includes a hopper 5, a discharge pipe 6, and a valve 7. The transport assembly 2 includes a conveyor belt 8 and a drive unit 9. The discharge port of the hopper 5 is connected to the upper end of the discharge pipe 6. The valve 7 is installed on the discharge pipe 6. The conveyor belt 8 is installed below the discharge pipe 6. The drive unit 9 is used to drive the conveyor belt 8 to rotate. The detector 4 includes an infrared sensor 10 and a receiver 11. The infrared sensor 10 is installed on the conveyor belt. On one side of the conveyor belt 8, the receiver 11 is installed on the other side. The infrared sensor 10, the receiver 11, and the valve 7 are all electrically connected to the controller 3. In use, the material is fed through the hopper 5 and the feeding pipe 6, and then the material falls onto the conveyor belt 8. When the material blocks the signal emitted by the infrared sensor 10, and the receiver 11 cannot receive the signal from the infrared sensor 10, it indicates that the material is falling too fast. The controller 3 then controls the valve 7 to close slightly to reduce the falling rate of the material. The present invention is simple to monitor, has low cost, and is easy to use.

[0024] In this embodiment, the infrared sensor 10 and the receiver 11 are 5-10cm above the conveyor belt 8. Specifically, the height can be adjusted according to requirements.

[0025] In this embodiment, to prevent materials from spilling from the side of the conveyor belt 8 during the conveying process, the conveyor belt 8 is arranged in an arc shape.

[0026] In this embodiment, the controller 3 is a PLC. The infrared sensor 10 and receiver 11 send signals to the PLC. The PLC controls the valve 7 through programming. This control process is common in the field, and the principle will not be described again here.

[0027] In this embodiment, to ensure the stability of the signal transmitted by the infrared sensor 10, at least two infrared sensors 10 are provided.

[0028] like Figure 1 As shown, in this embodiment, the feed pipe 6 is provided with an inspection port 12, the inner wall of the feed pipe 6 is provided with a first wear-resistant layer, and the conveyor belt 8 is provided with a second wear-resistant layer. The inspection port 12 of this utility model is used to quickly repair the feed pipe 6 when it becomes blocked. The first wear-resistant layer and the second wear-resistant layer of this utility model can improve the wear resistance of the feed pipe 6 and the conveyor belt 8 and extend their service life.

[0029] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
