From left to right, the base plate 3 is provided with a first vibrator 1, a second vibrator 2, an automatic feeding mechanism 6, and a weighing mechanism 9. The first vibrator 1 is provided with a first corrugated plate 4, and a material bin 13 is provided above the first corrugated plate 4. The second vibrator 2 is provided with a second corrugated plate 5. The second corrugated plate 5 is located above the automatic feeding mechanism 6 and is provided with a pressing mechanism 8.

[0022] Capsules 7, after coming down from the hopper 13, are first shaken apart by the first corrugated plate 4, then sorted one by one by the second corrugated plate 5, and then sent to the weighing platform by the automatic feeding mechanism 6 for weighing. After weighing, the automatic feeding mechanism 6 will send the weighed capsules 7 into the slide 10, and at the same time send the next capsule 7 onto the weighing platform. Capsules 7 with qualified weight enter the qualified material box 12, and those with unqualified weight will enter the unqualified material box 11 under the action of the flipping cylinder. The height of the second corrugated plate 5 is lower than that of the first corrugated plate 4.

[0023] The automatic feeding mechanism 6 includes a linear module 608, on which a motor mounting base plate 607 is provided. The motor mounting base plate 607 is provided with a motor support plate 6071 and a slide rail support plate 6072. A motor 601 is provided on the motor support plate 6071.

[0024] The motor drives the rotating wheel 606 to rotate, and the rotating wheel 606 drives the connecting rod 605 to move, thereby causing the needle mounting plate 603 to rise and fall on the guide rail 604, thus realizing the rising and falling movement of the needle 602.

The weighing sensor 902 is located at the bottom of the sensor mounting plate 901, and the weighing platform 903 is located on the side of the weighing sensor 902.

[0030] The design of the weighing sensor 902 and the weighing platform 903 in the weighing mechanism 9 ensures high-precision weighing and improves product quality.

[0031] Furthermore, in another embodiment, the weighing platform 903 is provided with a V-shaped groove, and a clearance groove is provided in the middle of the V-shaped groove.

[0032] The V-groove facilitates the placement of capsule 7 and prevents capsule 7 from sliding, while the clearance groove is used to avoid the pin.
