[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Figures 1 to 4 An embodiment of the feeding device of the present invention is shown. The feeding device of this embodiment includes a base 1, a vacuum feeder 2 provided on the base 1, and a connecting pipe 5. The base 1 is provided with a weighing component 3, and the weighing component 3 is provided with a material container 4. One end of the connecting pipe 5 is provided with a first breathing valve 51 and a first connecting joint 52, and the other end of the connecting pipe 5 is provided with a second breathing valve 54 and a second connecting joint 53. The discharge port of the material container 4 is connected to the first connecting joint 52, and the feed port of the vacuum feeder 2 is connected to the second connecting joint 53 via a feed pipe 24. The weighing component 3 can be, for example, an electronic scale, and the material container 4 can be, for example, a conical barrel.

[0027] The feeding device is provided with a weighing component 3 on the base 1, and the material container 4 is provided on the weighing component 3, so that the weight reduction of the material in the material container 4 can be detected in real time, and the vacuum loader 2 sucks the material into the vacuum loader 2 through negative pressure. It has a simple structure, is easy to use, and has a high degree of automation. The material container 4 is connected to the feeding pipe 24 of the vacuum loader 2 through a connecting pipe 5, and a first breathing valve 51 and a second breathing valve 54 are respectively provided at both ends of the connecting pipe 5. By switching the two breathing valves on and off, the phenomenon that the material in the feeding pipe 24 cannot all enter the vacuum loader 2 due to the existence of negative pressure can be avoided, which is conducive to ensuring the accurate feeding amount of the vacuum loader 2.

[0028] Furthermore, in this embodiment, the vacuum feeder 2 is provided with a vibrating component 21. When the vacuum feeder 2 adds material to the container 6 to be added, the vibrating component 21 vibrates to prevent the material from adhering to the vacuum feeder 2, which helps to add all the material in the vacuum feeder 2 to the container 6 to be added, ensuring the accurate addition amount.

[0029] Furthermore, in this embodiment, a discharge valve 22 is provided at the discharge port of the vacuum feeder 2, which may be a gate valve, etc. When the vacuum feeder 2 is feeding, the discharge valve 22 is closed; when materials need to be added to the container 6 to be fed, the discharge valve 22 is opened.

[0030] As a preferred technical solution, in this embodiment, the discharge port of the vacuum feeder 2 is connected to a discharge hose 25. The discharge port is connected to the discharge hose 25, which is convenient for docking with the container 6 to be charged.

[0031] Furthermore, in this embodiment, a swing arm 11 is provided on the base 1, and a mounting bracket 23 is provided on the vacuum loader 2. The mounting bracket 23 is hingedly connected to the swing arm 11, and the feed pipe 24 is a flexible tube. The hinged connection between the swing arm 11 and the mounting bracket 23 allows the position of the vacuum loader 2 on the base 1 to be flexibly adjusted to accommodate the different positions of the container 6 to be fed. The structure is simple, reliable, and easy to use.

[0032] Furthermore, in this embodiment, the material container 4 is mounted on a bracket 41, and braked wheels 42 are provided at the bottom of the base 1 and the bracket 41. The braked wheels 42 on the base 1 facilitate movement of the entire feeding device, making it more convenient to use. The braked wheels 42 at the bottom of the bracket 41 facilitate the material container 4 to move up and down the base 1. Once the base 1 and bracket 41 are in place, the brakes are locked to secure the base 1 and bracket 41, resulting in a simple and reliable structure.

[0033] The feeding method of the feeding device of this embodiment includes the following steps:

[0034] S1, vacuum loader 2 feeding:

[0035] S1.1. The discharge port of the material container 4 and the first breathing valve 51 are opened, the second breathing valve 54 is closed, the vacuum feeder 2 is turned on, and the material in the material container 4 enters the vacuum feeder 2 through the feed pipe 24;

[0036] S2.2. When the weight measured by the weighing component 3 drops to the set value, the discharge port of the material container 4 and the first breathing valve 51 are closed, the second breathing valve 54 is opened, and the material in the feeding pipe 24 enters the vacuum loader 2.

[0037] In this feeding method, when the vacuum loader 2 draws the material in the material container 4, the discharge port and the first breathing valve 51 of the material container 4 are opened, and the second breathing valve 54 is closed, and the material in the material container 4 enters the vacuum loader 2 through the feeding pipe 24; in order to allow all the material to enter the vacuum loader 2, the first breathing valve 51 is closed and the second breathing valve 54 is opened, and the vacuum loader 2 further performs suction to ensure the accuracy of the feeding amount.

[0038] Furthermore, in this embodiment, the feeding method further includes step S2, the vacuum feeder 2 discharges the material: the discharge port of the vacuum feeder 2 is opened (specifically, the discharge valve 24), the vibration component 21 vibrates, and the material enters the container to be fed 6. When the vacuum feeder 2 adds material to the container to be fed 6, the vibration component 21 vibrates, which can prevent the material from adhering to the vacuum feeder 2, which is conducive to adding all the material in the vacuum feeder 2 to the container to be fed 6, ensuring the accuracy of the feeding amount.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
