The push rod 3041 is located at the upper end of the filling tube 404. A plurality of support columns 6 are fixedly installed at the bottom of the pressure storage cylinder 301. The bottoms of the plurality of support columns 6 are commonly connected with a blowing tube 308. The blowing tube 308 is fixedly installed between the two cross beams 1 and is located at the periphery of the corrugated splash-proof bag 405. At least one air guide hole 309 is opened at the top of the blowing tube 308. The air guide hole 309 and the blowing tube 308 are connected to each other. 8 are connected to each other, a non-contact valve 3011 is fixedly installed on the periphery of the top opening of the air guide hole 309, a blowing air hole 307 is fixedly installed on the top of the non-contact valve 3011, and one end of the blowing air hole 307 away from the air guide hole 309 is fixedly connected to one of the output ends of the three-way pipe 303, the inner wall of the blowing cylinder 308 is arranged in a pleated shape, and the inner wall of the blowing cylinder 308 is provided with a plurality of blowing holes 3010 distributed at equal angles, and the blowing holes 3010 are arranged in multiple layers up and down, and the blowing holes 3010 are inclined at 45°; At least one guide block 3012 is fixedly installed on the top of the blowing cylinder 308, and the number and position of the guide blocks 3012 correspond to the number and position of the non-stop valves 3011.

A flange block 3016 is fixedly installed on the outer wall of the filling tube 404, and the number and position of the flange blocks 3016 correspond to the number and position of the slide bars 3013.

As the amount of barium sulfate crystals in the barium sulfate crystal filling cup from the filling component 4 continues to increase, the outer wall of the corrugated splash-proof bag 405 is squeezed, and the corrugated splash-proof bag 405 shrinks upward. At the same time, the upward shrinkage of the corrugated splash-proof bag 405 compresses the air inside it, and the air inside the corrugated splash-proof bag 405 is discharged into the interior of the pressure storage cylinder 301 through the pressure overflow hole 4011, the booster hose 305 and the check valve 306. Since the check valve 306 is in a unidirectional conductive state, the air entering the pressure storage cylinder 301 will not reversely enter the interior of the booster hose 305. As the pressure storage cylinder 3 01 The internal air increases continuously, and the internal pressure of the pressure storage cylinder 301 gradually increases, pushing the piston 304 together with the push rod 3041 downward. When the barium sulfate crystal filling cup is filled with barium sulfate crystals, it will no longer continue to compress the corrugated splash-proof bag 405, and the piston 304 moves downward to the lowest point.

Reset is achieved by reverse movement, and the reset of the sliding rod 3013 drives the valve stem of the stop valve 3011 to reset together, causing the stop valve 3011 to be turned on. As the filling tube 404 continues to move upward, its top gradually approaches the bottom of the push rod 3041 until they abut against each other. The filling tube 404 continues to move upward, pushing the push rod 3041 and the piston 304 upward, and the air inside the pressure storage cylinder 301 is transported to the inside of the blowing hole 307 through the circulating air hole 302 and the three-way pipe 303, and then input into the inside of the blowing tube 308 through the blowing hole 307, the stop valve 3011 and the air guide hole 309, and then blown out through a plurality of blowing holes 3010 to blow away the barium sulfate crystals attached to the outer wall of the corrugated splash-proof bag 405.

The filling tube 404 moves downward to drive the corrugated splash-proof bag 405 to move downward together, and the corrugated splash-proof bag 405 is inserted into the barium sulfate crystal filling cup until the bottom of the replenishing tube 407 is aligned with the barium sulfate crystal filling cup. After the bottom wall is touched, the servo gas rod 401 is immediately closed, and the filling tube 404 moves downward, driving the flange block 3016 to move together.

The barium sulfate crystals then enter the feeding bin 205, and are conveyed to the feeding tube 207 through the feeding hole 206, and then are conveyed to the filling tube 404 through the feeding tube 207. The barium sulfate crystals input into the filling tube 404 are discharged into the replenishing tube 407 through the corrugated telescopic tube 406, and then are discharged into the barium sulfate crystal filling cup through multiple overflow ports 408. As the amount of barium sulfate crystals in the barium sulfate crystal filling cup continues to increase, the outer wall of the corrugated anti-splash bag 405 is squeezed, and the corrugated anti-splash bag 405 shrinks upward. In addition, since the corrugated anti-splash bag 405 covers the top of the barium sulfate crystal filling cup, it can play an anti-splashing effect; At the same time, the upward contraction of the corrugated splash-proof bag 405 will compress the air inside it, and the air inside the corrugated splash-proof bag 405 will be discharged into the interior of the pressure storage cylinder 301 through the pressure overflow hole 4011, the boosting hose 305 and the check valve 306. Since the check valve 306 is in a unidirectional conductive state, the air entering the pressure storage cylinder 301 will not reversely enter the interior of the boosting hose 305. As the air inside the pressure storage cylinder 301 continues to increase, the pressure inside the pressure storage cylinder 301 gradually increases, pushing the piston 304 together with the push rod 3041 downward. When the barium sulfate crystal filling cup is filled with barium sulfate crystals, , the corrugated splash-proof bag 405 will no longer be compressed, the piston 304 moves downward to the lowest point, and then the servo gas rod 401 is started, and the output rod of the servo gas rod 401 moves upward to drive the lifting rod 403, the filling tube 404 and the corrugated splash-proof bag 405 to move upward and move away from the top of the barium sulfate crystal filling cup, and the filling tube 404 moves upward to drive the flange block 3016 to move together, so that the flange block 3016 is moved away from the end of the slide rod 3013, and the rebound force of the first reset spring 3015 is released, pushing the slide rod 3013 to move in the opposite direction to achieve reset, and the reset of the slide rod 3013 drives the stopper The valve stems of the through valve 3011 are reset together, causing the stop valve 3011 to be turned on. As the filling tube 404 continues to move upward, its top gradually approaches the bottom of the push rod 3041 until they abut against each other. The filling tube 404 continues to move upward, pushing the push rod 3041 and the piston 304 upward, and the air inside the pressure storage cylinder 301 is transported to the inside of the blowing hole 307 through the circulating air hole 302 and the three-way pipe 303, and then input into the inside of the blowing tube 308 through the blowing hole 307, the stop valve 3011 and the air guide hole 309, and then blown out through a plurality of blowing holes 3010. The barium sulfate crystals attached to the outer wall of the corrugated splash-proof bag 405 are blown away. When the filling tube 404 moves to the top dead center, the piston 304 also moves to the top dead center position. The top of the compensation air valve 4015 just abuts against the top wall of the blowing tube 308. The compensation air valve 4015 is pressurized to trigger the switch to achieve conduction. The external air enters the interior of the corrugated splash-proof bag 405 through the input end of the compensation air valve 4015 and the compensation hole 4013, balancing the air pressure inside and outside the corrugated splash-proof bag 405, and the corrugated splash-proof bag 405 is restored under the elastic reset action of the second reset spring 409.
