[0022] Embodiment 1

[0023] As Figures 1-4 , the utility model provides a quantitative feeder for preparing aluminum paste, which includes a base 1, a grinding machine body 2, and a power mechanism 3. The grinding machine body 2 includes a rotating cylinder 21. The base 1 serves as the supporting structure of the main body and is set on the factory ground. Both ends of the base 1 and the rotating cylinder 21 are rotatably connected. And a power mechanism 3 is arranged on one side of the base 1 to drive the rotating cylinder 21 to rotate. The common power mechanism 3 includes a motor and a gear speed change group. The motor is installed on the base 1, and one of the gears is fixed on the output shaft of the motor. Another gear is fixed on the outer side of the rotating cylinder 21, and the remaining gears are all rotatably connected to the base 1. By setting an appropriate tooth number ratio, the purpose of gear speed change is achieved. Since the specific structure of the power mechanism 3 is prior art, it will not be elaborated here.

[0024] A number of spheres are placed in the rotating cylinder 21. When the power mechanism 3 drives the rotating cylinder 21 to rotate, the spheres roll in the rotating cylinder 21. During the process of the spheres colliding with the inner wall of the rotating cylinder 21, the aluminum powder in contact will be refined and ground. This process is repeated to achieve the purpose of grinding the aluminum powder.

[0025] The grinding machine body 2 further includes an outlet 22 and a baffle 23. An outlet 22 with a suitable diameter is opened on the arc-shaped side wall of the cylindrical structure. During the rotation of the rotating cylinder 21, the outlet 22 will make an up-and-down turnover following the rotating cylinder 21. A baffle 23 is fixedly connected to the base 1, and a sampling port is opened on the baffle 23. The sampling port is always located below the rotating cylinder 21. When the rotating cylinder 21 drives the outlet 22 to move to the sampling port and the outlet 22 is aligned with the sampling port, a part of the aluminum powder in the rotating cylinder 21 will pass through the outlet 22 and the sampling port and move to the outside. At this time, a sampling bottle 25 is placed outside the sampling port to collect the falling aluminum powder.

[0026] The outer side wall of the rotating cylinder 21 and the inner side wall of the baffle 23 are in fitting rotation. In this way, when the outlet 22 rotates to a non-sampling port position, the aluminum powder will not leak out from the outlet 22.

[0027] Further, a sliding plate 24 is slidably connected to the bottom of the base 1, and a number of sampling bottles 25 are snap-connected within the sliding plate 24. By moving the sliding plate 24, the number of sampling bottles 25 can be successively moved below the sampling port. When a sampling bottle 25 is filled with aluminum powder for sampling, the sliding plate 24 is pushed to drive an empty sampling bottle 25 to move to the sampling port. Repeating this process, aluminum powder ground to different degrees at different time nodes can be obtained along with the progress of the grinding time.

[0028] Further, the linkage mechanism 26 enables the sliding plate 24 to move automatically driven by the power mechanism 3 without manual intervention. Specifically, the linkage mechanism 26 includes a first gear 261 and a second gear 262. The first gear 261 is fixed to the end face of the rotating cylinder 21, and the second gear 262 is fixed to the sliding plate 24. The first gear 261 and the second gear 262 are in meshing transmission. When the first gear 261 and the second gear 262 are engaged, the sliding plate 24 can be driven to slide on the base 1, thereby changing the positions of the respective sampling bottles 25 within the sliding plate 24 relative to the outlet 22.

[0029] One form of the linkage mechanism 26: The first gear 261 is a full-tooth structure, that is, the teeth required for meshing are evenly distributed along the outer edge of the first gear 261 in a circle. The second gear 262 is also correspondingly designed on the sliding plate 24. At this time, when the first gear 261 rotates continuously, the sliding plate 24 will be driven to move at a constant speed continuously. Inside this sliding plate 24, the sampling bottles 25 are placed closely to increase the probability that all the aluminum powder falls into the sampling bottles 25.

[0030] Another form of the linkage mechanism 26: The first gear 261 is a non-full-tooth structure, that is, the teeth required for meshing are only partially arranged at one or more places along the outer edge of the first gear 261. The teeth on the second gear 262 are also correspondingly arranged at multiple places in the extending direction of the sliding plate 24. Through multiple intermittent meshing transmissions between the first gear 261 and the second gear 262, the sampling bottles 25 within the sliding plate 24 are moved one by one below the outlet 22, so that the aluminum powder passes through the outlet 22 and then falls into the sampling bottles 25. In the above structure, an equal-spacing interval is maintained between the number of sampling bottles 25.

[0031] Regardless of the form of the linkage mechanism 26, a reasonable gear ratio is set so that each time the outlet 22 is transferred to the bottom, there is a corresponding sampling bottle 25, and each time the outlet 22 rotates one circle, the sampling bottle 25 filled with aluminum powder is moved out from under the outlet 22 under the transfer action of the slide plate 24, and a new unfilled sampling bottle 25 is moved to the bottom of the outlet 22 accordingly. This is repeated, and the purpose of obtaining aluminum powder samples with different grinding degrees at different time points can be achieved. At the same time, because the capacity of the sampling bottle 25 is fixed, the sampling bottle 25 can be quickly filled after the outlet 22 outputs the aluminum powder. Then, when the outlet 22 is transferred to the side of the sampling port, the outlet 22 is closed. At this time, a full bottle of aluminum powder sample can be obtained, and the purpose of quantitative sampling is also achieved.

[0032] In summary: by utilizing the cooperation of gear 1 261 and gear 2 262, the power mechanism 3 drives the drum 21 to rotate while sending each sampling bottle 25 to the bottom of the outlet 22, allowing aluminum powder samples of different coarseness and fineness to enter the corresponding sampling bottle 25, thereby achieving the purpose of automatic quantitative sampling.

[0033] Example 2

[0034] like Figures 1-4 On the basis of Example 1, a delivery bin 4 is mounted on the base 1. When the rotating drum 21 moves the outlet 22 to the output port of the delivery bin 4, and the outlet 22 is aligned with the output port, the aluminum powder in the delivery bin 4 falls into the drum 21. When the drum 21 drives the outlet 22 to rotate to the side of the delivery bin 4, the output port and the outlet 22 are staggered, and the outer wall of the drum 21 blocks the output port to prevent the leakage of aluminum powder. In this way, every time the drum 21 rotates one circle, the outlet 22 can be aligned with the output port of the delivery bin 4 once, so that a certain amount of aluminum powder can enter the drum 21, and roughly quantitative feeding is achieved.

[0035] Example 3

[0036] like Figures 1-4 On the basis of Example 1, a stirring plate 28 is connected to the drum 21. When the stirring plate 28 rotates, the aluminum powder entering the drum 21 from the outlet 22 is dispersed.

[0037] The rotating drum 21 and the stirring plate 28 are connected in a fixed manner. The rotating drum 21 and the stirring plate 28 rotate at the same frequency and speed to break up the aluminum powder in the rotating drum 21 .

[0038] The drum 21 and the stirring plate 28 are connected in a rotational manner. The stirring plate 28 and the drum 21 rotate at different speeds. The accumulation of aluminum powder on one side of the stirring plate 28 forms a force that drives the stirring plate 28 to rotate, thereby effectively breaking up the aluminum powder entering the drum 21.

[0039] Preferably, the stirring plate 28 is designed to be inclined.

[0040] Preferably, a resistance rod 29 is fixed on the inner wall of the rotating drum 21. When the rotating stirring plate 28 contacts the resistance rod 29, the stirring plate 28 is interfered and vibrates, thereby shaking off the aluminum powder attached to the stirring plate 28.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
