A plurality of conveying rollers 17 are rotatably connected to the conveying frame 14, and a conveying belt 18 is set between the plurality of conveying rollers 17. The conveying belt 18 is provided with a plurality of grooves, and a plurality of weight sensors 19 are installed on the conveying belt 18. A pushing frame 20 is fixedly connected to the vibration frame 3, and a third fixed frame 21 is fixedly connected to the pushing frame 20, and a first electric push rod 22 is fixedly installed on the third fixed frame 21. The first electric push rod 22 is connected to the telescopic rod with a first connecting rod 23, and the pushing frame 20 is slidably connected to a moving block 24, the moving block 24 is connected to the first connecting rod 23, and a second electric push rod 25 is fixedly installed on the moving block 24. The bottom end of the telescopic rod of the second electric push rod 25 is connected to a second connecting rod 26, and the bottom end of the second connecting rod 26 is connected to a scraper pushing plate 27. The scraper pushing plate 27 is used to scrape and push impurities, and a telescopic rod 28 is connected between the scraper pushing plate 27 and the moving block 24.

[0019] Two third electric push rods 29 are fixedly mounted on the vibration frame 3 . The telescopic rods of the third electric push rods 29 are connected to third connecting rods 30 . A closing plate 31 is slidably connected to the vibration frame 3 . The closing plate 31 is connected to the third connecting rod 30 .

[0020] The working principle of the utility model is as follows: in the first step, after the finished barrels are placed one by one in the groove of the conveyor belt, the second drive motor is controlled to drive the second rotating shaft, the conveyor roller and the conveyor belt to rotate, so that the conveyor belt transports the finished barrels. After the finished barrels are transported to the bottom of the discharge pipe of the vibration frame, the second drive motor is controlled to stop.

[0021] The second step is to control the first drive motor to drive the first shaft and the cam to rotate. After the cam rotates to contact the sliding rod, the sliding rod and the filter screen are driven to rise, and the spring is deformed. After the cam rotates and disengages from the sliding rod, the spring is reset, thereby driving the sliding rod and the filter screen to descend. The filter screen is lifted and lowered to achieve a vibration screening effect. Then, the fireworks drug is poured into the filter screen in the vibration frame. The filter screen will screen the fireworks drug and separate the impurities in the fireworks drug to prevent the impurities from affecting the quality of the fireworks drug, thereby achieving screening. Subsequently, the electric valve is controlled to open the discharge pipe channel of the vibration frame, so that the fireworks drug falls into the finished product barrel through the discharge pipe channel of the vibration frame. When the weight of the fireworks drug in the finished product barrel reaches the preset threshold of the weight sensor, the electric valve is controlled to close the discharge pipe channel of the vibration frame for a certain period of time and then continue to open. At the same time, the second drive motor is controlled to stop working for a certain period of time. The second drive motor drives the second shaft, the conveyor roller and the conveyor belt to rotate. The conveyor belt drives the finished product barrel containing fireworks drug away from the discharge pipe of the vibration frame, and drives the finished product barrel without fireworks drug to the bottom of the discharge pipe of the vibration frame.

[0022] The third step is that after the fireworks medicine is screened, the first drive motor and the electric valve are controlled to stop working, and then the third electric push rod is controlled to drive the third connecting rod and the closing plate to rise, thereby opening the channel between the vibration frame and the impurity collection box, and then the second electric push rod is controlled to drive the second connecting rod and the scraper push plate to descend to a specified height, and the telescopic rod is extended, and then the first electric push rod is controlled to drive the first connecting rod, the moving block, the second electric push rod, the second connecting rod, the scraper push plate and the telescopic rod to move a certain distance. During the movement, the scraper push plate scrapes the impurities on the filter screen and pushes them so that the impurities enter the impurity collection box, thereby facilitating the collection of impurities. After the impurities are collected, the second electric push rod is controlled to drive the second connecting rod and the scraper push plate to rise to reset, and the telescopic rod is shortened, and then the first electric push rod is controlled to drive the first connecting rod, the moving block, the second electric push rod, the second connecting rod, the scraper push plate and the telescopic rod to move in the opposite direction to reset, and finally the third electric push rod is controlled to drive the third connecting rod and the closing plate to descend, thereby closing the channel between the vibration frame and the impurity collection box.
