[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set" and "connection" 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, a direct connection, or an indirect connection through an intermediate medium; or 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 Figures 1 to 4As shown, this embodiment provides a dual-station rapid feeding device combining coarse and fine feeding, including a coarse feeding hopper 1, a fine feeding hopper 2, a first vibrator 3 located at the bottom of the coarse feeding hopper, a second vibrator 4 located at the bottom of the fine feeding hopper, a weighing module 5, and a material cup 6 located on the weighing module; wherein, the bottom surface of the coarse feeding hopper 1 is inclined, and a wide discharge trough 7 is provided at the outer end. The wide discharge trough 7 is connected to the interior of the coarse feeding hopper 1 and is located near the deepest part of the interior of the coarse feeding hopper 1. A first baffle 9 is provided at the connection between the wide discharge trough 7 and the coarse feeding hopper 1. The coarse feed at the connection between the wide discharge trough 7 and the coarse feeding hopper 1 is adjusted by the first baffle 9. The size of the discharge port; the bottom surface of the fine feeding hopper 2 is inclined, and a narrow discharge trough 8 is provided at the outer end. The narrow discharge trough 8 is connected to the interior of the fine feeding hopper 2 and is located near the deepest part of the interior of the fine feeding hopper 2. A second baffle 10 is provided at the connection between the narrow discharge trough 8 and the fine feeding hopper 2. The size of the fine discharge port at the connection between the narrow discharge trough 8 and the fine feeding hopper 2 is adjusted by the second baffle 10; the feed pipe has an inverted Y-shaped structure. The end faces of the two discharge ports of the feed pipe are inclined surfaces that cooperate with the bottom inclined surfaces of the coarse feeding hopper 1 and the fine feeding hopper 2. They extend into the coarse feeding hopper 1 and the fine feeding hopper 2 respectively and maintain a gap of 5-10mm from the bottom.

[0024] It should be noted that in this embodiment, the first vibrator 3 and the second vibrator 4 can be existing vibrators, which are not key points of this application and therefore will not be described in detail; the first baffle 9 and the second baffle 10 can be manually adjustable baffles, and the specific installation form can refer to the existing baffle structure design, which is also not a key point of this application. The baffles are added in this embodiment mainly to facilitate the adjustment of the size of the coarse discharge port and the fine discharge port according to different materials, but no matter how they are adjusted, the coarse discharge port is significantly larger than the fine discharge port.

[0025] Furthermore, such as Figure 1 , Figure 2 As shown, in this embodiment, the wide discharge trough 7 on the coarse feeding bin 1 is adjacent to the narrow discharge trough 8 on the fine feeding bin 2, and the discharge ports at the other ends of the wide discharge trough 7 and the narrow discharge trough 8 are both located above the material cup 6. The material is conveyed into the material cup 6 through the wide discharge trough and the narrow discharge trough.

[0026] Furthermore, such as Figure 3 , Figure 4 As shown, in this embodiment, the coarse feeding bin 1 is provided with a first connecting frame connected to the first vibrator on both sides, and the fine feeding bin 2 is provided with a second connecting frame 201 connected to the second vibrator on both sides; the first connecting frame and the second connecting frame are L-shaped structures, and mounting holes (unmarked) are machined on the horizontal surface at the bottom, which are respectively fixed to the mounting bases of the first vibrator 3 and the second vibrator 4 by bolts.

[0027] It should be noted that in this embodiment, since the coarse feeding bin 1 and the fine feeding bin 2 have basically the same bin structure, only the fine feeding bin is used as an example and described in detail.

[0028] Furthermore, continue as Figure 1 As shown in this embodiment, the top covers (unmarked) of the coarse feeding bin 1 and the fine feeding bin 2 are both machined with circular mounting holes. The two outlets of the feed pipe extend into the coarse feeding bin and the fine feeding bin through the circular mounting holes. This design prevents material overflow when the vibrator is not activated, as the inclined surface at the bottom of the coarse feeding bin and the fine feeding bin contacts and cooperates with the feed pipe port. When the vibrator is activated, the vibrator can create a gap between the feed pipe port and the inclined surface at the bottom of the bin, allowing the material to pass smoothly through the inclined surface into the deepest part of the bin and be transported to the material cup through the wide discharge chute and the narrow discharge chute.

[0029] Furthermore, both the wide discharge trough 7 and the narrow discharge trough 8 are inclined, and the slope (inclination) of the bottom slope of the wide discharge trough 7 is greater than the slope of the bottom slope of the narrow discharge trough 8.

[0030] When this feeding device is used, if the target weight is 10g, the material is conveyed through a funnel and an inverted Y-shaped feeding pipe. The two outlets of the inverted Y-shaped feeding pipe extend into the coarse feeding bin 1 and the fine feeding bin 2 respectively and are in contact with the inclined surfaces at the bottom. Initially, only the first vibrator 3 at the bottom of the coarse feeding bin is activated, and the second vibrator 4 at the bottom of the fine feeding bin is not activated. The material in the feeding pipe flows into the coarse feeding bin 1 under the action of the inclined surfaces at the bottom of the bin and the first vibrator, and is conveyed to the material cup 6 through the wide discharge chute 7. Due to the wide discharge chute 7 and the coarse discharge... The opening is relatively large, so the material in the cup is quickly added to near the target weight. When the weighing module detects that the material in the cup is close to the target weight, that is, greater than 8.5g, the second vibrator 4 is activated and the first vibrator 3 is turned off. The material in the feed pipe flows into the fine feeding hopper 1 under the action of the bottom slope of the hopper and the second vibrator, and is transported to the cup 6 through the narrow discharge chute 7. Since the narrow discharge chute 7 and the fine discharge opening are small, the accuracy can be guaranteed. The coarse and fine feeding method can guarantee both feeding speed and accuracy.

[0031] The above describes specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
