For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The utility model provides a powder batching system, comprising a horizontal conveyor belt 1, a first buffer component, a mixing component, a second buffer component, and a packaging component, wherein at least two groups of weighing and feeding components are arranged on the horizontal conveyor belt 1. All weighing and feeding components are arranged in sequence above the horizontal conveyor belt 1, and each group of weighing and feeding components includes a storage bin 21 and a weighing unit 22 placed between the storage bin 21 and the horizontal conveyor belt 1; the first buffer component is used to receive and store the powder conveyed by the horizontal conveyor belt 1; the mixing component is used to mix the powder in the buffer component; the second buffer component is used to cache the mixing component; and the packaging component is used to package the classification in the second buffer component.

[0030] With the above scheme, the number of weighing and feeding components is determined according to the type of raw materials, and the number is greater than or equal to the type of raw materials. All weighing and feeding components are sequentially arranged above the horizontal conveyor belt 1, and all weighing and feeding components can be unloaded onto the horizontal conveyor belt 1, avoiding the setting of multi-component conveyor belts, simplifying the structure, and saving costs.

[0031] The horizontal conveyor belt 1, the first buffer component, the mixing component, the second buffer component, the packaging component, and the weighing and feeding component can be implemented by using existing mature structures. In order to further improve the system performance, some components can also be implemented by using the following structures.

[0032] In order to simplify the structure of the weighing unit, such as Figure 2 As shown, the weighing unit 22 includes a second frame 221 , a third silo 222 , at least two weighing ears 223 fixed on the side walls of the third silo 222 , and a weighing sensor 224 placed between the second frame 221 and the weighing ears 223 .

[0033] In order to simplify the setting height of the horizontal conveyor belt 1, simplify the structure and save costs, the first cache component includes a first silo 31 and a first climbing conveyor 32 for transferring powder on the horizontal conveyor belt 1 to the first silo; the bottom of the first silo 31 is conical.

[0034] The mixing assembly includes a first frame 41 , a vacuum loader 43 connected to the first cache assembly through a feed pipe 42 , and a mixer 44 placed below the vacuum loader 43 . Both the vacuum loader 43 and the mixer 44 are fixed on the first frame 41 .

[0035] The second buffer assembly includes a second silo 51 and a first screw feeder 52 for transferring the powder in the mixing assembly to the second silo 51. In order to facilitate the control of the discharge of the second silo 51, as shown in FIG. Figure 3 , 4As shown, the second silo 51 includes a cylindrical upper cylinder 511 and a conical lower cylinder 512, and a first discharge port 5121 is arranged on the side wall of the lower cylinder 512, and a closed door 5122 is rotatably connected to the discharge port, and a first pneumatic cylinder 5123 is rotatably connected between the lower cylinder 512 and the closed door 5122 to realize the control of the closed state of the first discharge port 5121 by the closed door 5122.

[0036] It should be noted that the first material bin 31 may adopt the same structure as the second material bin 51. The pneumatic cylinder is used to realize control, which has a simple structure and is easy to control.

[0037] The packaging assembly includes a bag packaging machine 61 and a second screw feeder 62 for conveying the powder in the second buffer assembly to the bag packaging machine 61. The bag packaging machine 61 is a prior art, and the specific structure is not described in detail in this solution.

[0038] like Figure 5 , 6 As shown, the second screw feeder 62 includes a feeding barrel 621, one end of which is provided with a feeding port 6211, and the other end is provided with a second discharging port 6212; a screw shaft 622 placed in the feeding barrel 621; a driving member 623 for driving the screw shaft 622 to rotate; a control structure arranged on the feeding port 621, the control structure including at least one opening and closing plate 624, a first control plate 625 one end of which is non-vertically fixed to the opening and closing plate 624, a second control plate 626 rotatably connected to the other end of the first control plate 625, a second pneumatic cylinder 627 for controlling the second control plate 626 along one radial end of the feeding port 6211, and a limiting portion 628 fixed on the inner wall of the feeding port 6211 and overlapping with the opening and closing plate 624.

[0039] The feed port 6211 is square or circular, and the opening and closing plate 624 can also be directional or circular. The limiting portion 628 also seals the edge of the opening and closing plate 624 when limiting the support of the opening and closing plate 624. One or more opening and closing plates 624 can be provided. In order to simplify the structure and facilitate the rotation control of the opening and closing plate 624, there are two opening and closing plates 624 and the two opening and closing plates 624 overlap. The two opening and closing plates 624 overlap, and the overlapping portion improves the reliability of the seal.

[0040] The angle between the opening and closing plate 624 and the first control plate 625 is less than 90 degrees, preferably set to 40 to 50 degrees. In order to facilitate the connection of the second pneumatic cylinder 627, a mounting hole is set on the side wall of the feed port 6211. In order to ensure sealing, the aperture of the mounting hole is adapted to the telescopic end of the second pneumatic cylinder 627. The second pneumatic cylinder 627 is fixed to the outer wall of the feed barrel 621, and its telescopic end is fixedly connected to the second control plate 626. It should be noted that Figure 5 , 6 The second pneumatic cylinder 627 and the second control plate 626 are not assembled in place.

[0041] Using the above structure, refer to Figure 5 , 6 Since the opening and closing plate 624 and the first control plate 625 are not in a vertical fixed relationship, when the feed port 6211 needs to be closed, refer to Figure 5 , the second pneumatic cylinder 627 controls the second control plate 626 to move rightward, and due to the action of the limiter 628 and the first control plate 625, the opening and closing plate 624 is parallel to the diameter surface of the feed port 6211, so that the feed port 6211 is sealed. Figure 5 shown.

[0042] When the material feeding is to be continued, the second pneumatic cylinder 627 controls the second control plate 626 to move leftward, and the limiter 628 loses the locking effect on the opening and closing plate 624. Under the gravity of the opening and closing plate 624 and the first control plate 625, the first control plate 625 is in a substantially vertical state, so that the feed port 6211 is opened. Figure 6 shown.

[0043] The first screw feeder 52 may also adopt the same structure as the second screw feeder 62 .

[0044] The powder batching system also includes an intelligent control unit to achieve coordinated control of various components in the system. The structure of the control unit and its connection relationship with the control parts in each component are both existing technologies and will not be described here.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
