[0013] 1. The automatic dosage weighing and packaging machine sets a weighing structure, pours the medicine into the storage box through the feed port, opens the solenoid valve, and the medicine enters the weighing cylinder through the discharge port and the hose. After the gravity sensor senses a certain gravity, the solenoid valve is closed, and the second motor runs to drive the weighing cylinder to select through the rotating rod, so that the weighing cylinder tilts, and the electric hinged door is opened, so that the medicine inside the weighing cylinder falls into the inside of the packaging box, which is convenient for automatic weighing of medicines, reduces errors, and prevents drug contamination.

[0014] 2. The automatic dosage weighing packaging machine sets up a packaging structure to place the packaging box on the top of the limit seat. The conveyor runs to transport the packaging box to the bottom of the weighing cylinder. When the weighing cylinder is tilted, the medicine falls into the inside of the packaging box. After the weighing cylinder returns to its original state, the conveyor continues to run and repeats the operation, which facilitates automatic packaging and improves the packaging speed.

[0023] The weighing structure 4 includes a motor 1 401, a rotating shaft 402, a connecting rod 403, a brush rod 404, a discharge port 405, a solenoid valve 406, a motor 2 407, a rotating rod 408, a weighing cylinder 409, an electric hinged door 4010, a hose 4011 and a gravity sensor 4012. The top of the housing 1 is fixedly connected to the motor 1 401, the output end of the motor 1 401 is provided with a rotating shaft 402, the outside of the rotating shaft 402 is fixedly connected to the connecting rod 403, and the outside of the connecting rod 403 is fixedly connected to A brush rod 404, a discharge port 405 is fixedly connected to the bottom of the storage box 3, a solenoid valve 406 is arranged outside the discharge port 405, a motor 2 407 is fixedly connected to the back of the shell 1, a rotating rod 408 is arranged at the output end of the motor 2 407, a weighing cylinder 409 is fixedly connected to the front of the rotating rod 408, an electric hinged door 4010 is hinged on the right side of the weighing cylinder 409, a hose 4011 is fixedly connected to the top of the weighing cylinder 409, and a gravity sensor 4012 is arranged on the inner bottom wall of the weighing cylinder 409.

[0024] The packaging structure 5 includes a conveyor 501, a limiting seat 502 and a packaging box 503. The conveyor 501 is arranged inside the shell 1, and a number of limiting seats 502 are fixedly connected to the outside of the conveyor 501. The packaging boxes 503 are placed on the top of the limiting seats 502.

[0025] In the case implementation, the hose 4011 will not affect the rotation of the weighing cylinder 409, so that the medicine can continue to enter the interior of the weighing cylinder 409 through the hose 4011 after the weighing cylinder 409 returns to its original state.

[0026] In the case implementation, the conveyor 501 runs from left to right, the packaging box 503 is put in from the left side, and the packaging box 503 is recovered from the right side.

[0027] In the case implementation, a controller and a transparent window are provided on the front of the housing 1 to facilitate the control and observation of the interior of the housing 1.

[0028] In the case implementation, a limit rod is fixedly connected to the front of the weighing cylinder 409, and the limit rod is rotatably connected to the inner front wall of the shell 1 to reduce the damage of the gravity of the weighing cylinder 409 to the rotating rod 408.

[0029] When implementing, follow these steps:

[0030] 1) First, pour the medicine into the storage box 3 through the feed port 2;

[0031] 2) Then the packaging box 503 is placed on the top of the limiting seat 502, and the conveyor 501 operates to transport the packaging box 503 to the bottom of the weighing cylinder 409;

[0032] 3) Open the solenoid valve 406 again, and the medicine enters the weighing cylinder 409 through the discharge port 405 and the hose 4011. After the gravity sensor 4012 senses that a certain gravity has been reached, the solenoid valve 406 is closed, and the motor 2 407 drives the weighing cylinder 409 to select through the rotating rod 408, so that the weighing cylinder 409 is tilted, and the electric hinged door 4010 is opened, so that the medicine inside the weighing cylinder 409 falls into the inside of the packaging box 503;

[0033] 4) Finally, after the weighing cylinder 409 returns to its original state, the conveyor 501 continues to run and repeats the operation.

[0034] To sum up, the automatic dosage weighing and packaging machine, by setting up a weighing structure 4, pours the medicine into the interior of the storage box 3 through the feed port 2, opens the solenoid valve 406, and the medicine enters the weighing cylinder 409 through the discharge port 405 and the hose 4011. After the gravity sensor 4012 senses that a certain gravity has been reached, the solenoid valve 406 is closed, and the motor 2 407 runs to drive the weighing cylinder 409 to select through the rotating rod 408, so that the weighing cylinder 409 is tilted, and the electric hinged door 4010 is opened, so that the medicine inside the weighing cylinder 409 falls into the interior of the packaging box 503.

[0035] Furthermore, by setting up the packaging structure 5, the packaging box 503 is placed on the top of the limiting seat 502, and the conveyor 501 is operated to transport the packaging box 503 to the bottom of the weighing cylinder 409. When the weighing cylinder 409 is tilted, the medicine falls into the interior of the packaging box 503. After the weighing cylinder 409 returns to its original state, the conveyor 501 continues to run and repeats the operation, thereby solving the problem that manual packaging is not only extremely inefficient, but also the operator himself may cause contamination to the medicine to a certain extent during the operation.
