[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] See Figure 1-6 A quantitative sampling device includes a base 2 positioned directly below a hopper 1. The base 2 has a through hole communicating with the discharge port of the hopper 1. The base 2 is fixed to a mounting frame 3. A support platform 4 is mounted on the mounting frame 3 directly below the base 2. A U-shaped frame 5 is slidably mounted on the support platform 4. The U-shaped frame 3 consists of displacement plates on its upper and lower sides and a free end connected by a connecting plate. The two displacement plates are seamlessly connected to the base 2 and the support platform 4, respectively. The upper surface of the U-shaped frame 5 is slidably connected to the base 2. A C-shaped through groove is formed on the side of the U-shaped frame 5 near the discharge port of the hopper 1, and a C-shaped blind groove is formed on the side of the U-shaped frame 5 near the support platform 4. The C-shaped through groove and the C-shaped blind groove are opposite each other, and the opening directions of the C-shaped through groove and the C-shaped blind groove are opposite to the sliding direction of the U-shaped frame 5. A measuring cup 6 is perpendicular to the U-shaped frame. The upper end of the measuring cup 6 is located in the C-shaped through groove, and the lower end is located in the C-shaped blind groove. The upper end of the measuring cup 6 is flush with the upper surface of the U-shaped frame. A baffle plate 7 is horizontally connected to the upper end of the measuring cup 6 at the opening side of the C-shaped through groove. The baffle plate 7 is flush with the side of the U-shaped frame 5. The outer periphery of the baffle plate 7 is seamlessly connected to the C-shaped through groove. The U-shaped frame 5 is connected to a linear reciprocating mechanism 8. The U-shaped frame 5 reciprocates through the linear reciprocating mechanism 8. A vibration motor 9 is provided on the lower side of the support platform 4. The vibration motor 9 is used to prevent a vacuum state when the measuring cup 6 is filled, thus reducing the amount of powder in the measuring cup 6. The vibration motor 9 and the linear reciprocating mechanism 8 are electrically connected to a controller through signal lines.

[0023] A limiting plate 10 is provided in the preferred C-shaped blind groove. The limiting plate 10 has a placement hole that matches the outer diameter of the measuring cup 6. The outer side of the limiting plate 10 is flush with the side of the U-shaped frame 5. The setting of the limiting plate 10 can further prevent the measuring cup 6 from being displaced when the vibration motor 9 vibrates.

[0024] A retaining ring 11 is vertically provided on the limiting plate 10 outside the preferred placement hole. The inner diameter of the retaining ring 11 is in close contact with the outer diameter of the measuring cup 6. The retaining ring 11 effectively enhances the stability of the measuring cup 6.

[0025] The preferred measuring cup 6 has multiple smaller measuring cups inside, and the outer surface of the upper surface of the smaller measuring cups is in contact with the inner surface of the adjacent measuring cups, which can realize the quantitative dispensing of multiple doses.

[0026] The preferred base 2 has sliding grooves 12 on both sides of the through hole on its lower surface and on both sides of the support platform 4 directly below it. The upper and lower sides of the U-shaped frame 5 are respectively provided with sliders 13 that are adapted to the sliding grooves 12.

[0027] The preferred linear reciprocating mechanism 8 includes a telescopic cylinder 801 and a connecting block 802. The telescopic cylinder 801 is fixed on the mounting bracket 3 on one side of the measuring cup 6. The output end of the telescopic cylinder 801 is vertically fixed to the connecting block 802. The end of the connecting block 802 is fixedly connected to the U-shaped frame 5 by screws. The telescopic cylinder 801 is electrically connected to the controller through a signal line. When in use, the controller starts the telescopic cylinder 801 to work, which pulls or pushes the connecting block 802, thereby causing the U-shaped frame 5 to move forward or backward.

[0028] A baffle 14 is vertically fixed to the support platform 4 on one side of the preferred C-shaped blind groove. The upper end of the baffle 14 is fixed to the base 2. The baffle 14 can prevent the limiting plate 10 and the baffle plate 7 at the upper end of the measuring cup 6 from being displaced when the vibration motor 9 vibrates.

[0029] A limiting strip 15 is preferably fixed horizontally on the inner side of the baffle 14. The limiting strip 15 is set tightly against the outer wall of the measuring cup 6 on the side away from the baffle 14. The design of the limiting strip 15 makes the measuring cup 6 more stable when taking out materials.

[0030] The working principle of this utility model is as follows: When taking materials, first, the powder is loaded into the hopper 1, and then the vibration motor 9 is started. Through the transmission of the vibration force of the vibration motor 9, the material above it vibrates simultaneously, so that the powder in the hopper 1 gradually enters the measuring cup 6 through the vibration force. After a certain period of time, the vibration motor 9 is turned off, and then the telescopic cylinder 801 is started. The telescopic cylinder 801 pulls the connecting block 802 to pull the U-shaped frame 5. At this time, the sliders 13 on the upper and lower sides of the U-shaped frame 5 slide along the slide groove 12. When the end of the U-shaped frame 5 is far away from the baffle 14, the telescopic cylinder 801 is turned off. Then, the measuring cup 6 is removed and the powder in the measuring cup 6 is taken out. After the measuring cup 6 is put into the placement hole, the telescopic cylinder 801 is started again to move the measuring cup 6 to the original position. By repeating this process, the amount of material taken out each time can be kept consistent, and quantitative material taking can be achieved.
