A total material door 9 is arranged at the discharging ends of the second channel 61 and the second channel 62, and the total material door 9 is used for switching the opening and closing of the first channel 61 and the second channel 62.

[0021] During operation, the feeding ends of the first channel 61 and the second channel 62 are opened. The medicine grains in the bin 2 enter the blanking block 4 along the conveying channel 3, and then enter the optical detection channel of the photoelectric eye box 5 through the blanking block 4. After being counted by the optical detection photoelectric eye and the control system, they are collected in the first channel 61 and the second channel 62 of the gate assembly 6. When the number of medicine grains in the first channel 61 and the second channel 62 reaches the set bottling quantity, the servo motor drives the first small gate 71 and the second small gate 72 to rotate. The first small gate 71 is used to close the feeding end of the first channel 61, and the second small gate 72 is used to close the feeding end of the second channel 62. At the same time, the main gate 9 is opened, so that the medicine grains in the first channel 61 and the second channel 62 fall into the strip packages respectively; if the number of medicine grains in the first channel 61 reaches the set bottling quantity, while the number of medicine grains in the second channel 62 does not reach the set bottling quantity, the feeding end of the first channel 61 is closed by the first small gate 71, the main gate 9 is opened to open the discharging end of the first channel 61 so that the medicine grains in the first channel 61 fall into the strip package, and at the same time the second small gate 72 is opened, so that the medicine grains counted by the photoelectric eye box 5 are collected in the second channel 62, and the discharging end of the second channel 62 is closed by the main gate 9, and vice versa. The photoelectric eye box 5 is a product available on the market.

[0023] The gate assembly 6 includes a connecting plate 63, a mounting plate 64, a partition plate 65, and two guide plates 66. The connecting plate 63 is connected to the mounting plate 64 through a connecting column 67. The two guide plates 66 are symmetrically arranged on the mounting plate 64. The partition plate 65 is arranged between the two guide plates 66 and divides them into a first channel 61 and a second channel 62. The first small gate 71 and the second small gate 72 are respectively rotatably arranged on the mounting plate 64. One ends of the first small gate 71 and the second small gate 72 are respectively connected to a servo motor 81, and the servo motor 81 is arranged on the connecting plate 63. Arc-shaped receiving grooves 68 are respectively formed on the two guide plates 66 in a mirror-symmetrical manner.

[0024] Refer to Figure 5 and Figure 6 The first small material gate 71 and the second small material gate 72 are respectively independently controlled by a servo motor 81 to rotate. When the first small material gate 71 and the second small material gate 72 rotate to both sides of the first channel 61 and the second channel 62, the feeding ends of the first channel 61 and the second channel 62 are opened; when the first small material gate 71 and the second small material gate 72 rotate to the middle of the first channel 61 and the second channel 62, the feeding ends of the first channel 61 and the second channel 62 are closed; the total material gate driving motor 82 controls the rotation of the total material gate 9. When the total material gate 9 rotates into the arc-shaped accommodating groove 68, the discharging ends of the first channel 61 and the second channel 62 are opened; when the total material gate 9 rotates to the discharging ends of the first channel 61 and the second channel 62, the discharging ends of the first channel 61 and the second channel 62 are closed; when a part of the total material gate 9 is located in the arc-shaped accommodating groove 68 and the other part is located at the discharging end of the first channel 61, the discharging end of the first channel 61 is closed and the discharging end of the second channel 62 is opened; when a part of the total material gate 9 is located in the arc-shaped accommodating groove 68 and the other part is located at the discharging end of the second channel 62, the discharging end of the second channel 62 is closed and the discharging end of the first channel 61 is opened.
