[0021] Reference Figure 1-5 A device for rejecting defective emulsion explosive cartridges includes a workshop 1. A conveyor 2 and a telescopic cylinder 3 are fixed to the side wall of the workshop 1. Each output end of the telescopic cylinder 3 is threaded with a connecting part 4. An electromagnet 5 is fixed to the side wall of each connecting part 4. A support frame 6 is fixed to the ground of the workshop 1. An installation pipe 7 is movably installed on the inner ring of the support frame 6. A bearing is fixed between the support frame 6 and the installation pipe 7. A machine compartment 8 is fixed to the side wall of the installation pipe 7. Multiple detection tubes 9 are fixed in a circular array on the outer surface of the machine compartment 8. A sleeve tube 10 is sealed inside the detection tube 9. The sleeve tube 10 is replaceable and washable. A cartridge placement component 11 and a port cap 12 are respectively sealed at both ends of the sleeve tube 10. (Reference) Figure 4 A sealing ring is provided between the detection tube 9 and the sleeve tube 10, a sealing ring is provided between the medicine roll placement component 11 and the sleeve tube 10, a sealing ring is provided between the detection tube 9 and the port cap 12, and a sealing ring is provided between the sleeve tube 10 and the port cap 12 to ensure the sealing effect inside the detection tube 9.

[0022] Multiple first electrically controlled valves 13 are fixed in a circular array on the surface of the mounting tube 7. A negative pressure pump 14 is fixed to the internal side wall of the housing 8. A gas guide ring 15 is fixed to the output end of the negative pressure pump 14. The gas guide ring 15 is used to centrally extract gas. By controlling the first electrically controlled valve 13 and the second electrically controlled valve 19 in coordination, a vacuum is evacuated or the gas pressure is restored in a single detection tube 9. An exhaust pipe 16 is sequentially fixed and connected between the gas guide ring 15, the first electrically controlled valve 13, and the port cover 12. A vacuum sensor 17, using a Leybold DU 2001 Rel. Pressure sensor, is fixed on the surface of the exhaust pipe 16 and located inside the housing 8. Vacuum sensor 17 has an air inlet pipe 18 fixed to the side wall of port cover 12. A second electrically controlled valve 19 is fixed to the surface of the air inlet pipe 18. During detection, a negative pressure pump 14 draws in concentrated gas, which is then concentrated into the gas guide ring 15 through an exhaust pipe 16. During this process, the first electrically controlled valve 13 and the second electrically controlled valve 19 work together to guide the gas. When detecting the explosive cartridge in the detection tube 9, the first electrically controlled valve 13 opens and the second electrically controlled valve 19 closes. The negative pressure pump 14 draws in the gas in the detection tube 9. If there is a tear on the surface of the explosive cartridge, the emulsion explosive inside the cartridge will flow out from the tear. After the vacuum detection is completed, the first electrically controlled valve 13 closes and the second electrically controlled valve 19 opens to replenish air in the detection tube 9. During the detection process, the vacuum sensor 17 detects the relationship between time and pressure changes and compares it with a mathematical model to determine whether there is a leak. This detection technology is existing technology and will not be described in detail here.

[0023] In addition to the above structure, it also includes a terminal controller, which is electrically connected to each electrical component and appliance, and is used to comprehensively control the coordinated operation of each electrical component and appliance.

[0024] The drug roll placement assembly 11 includes an inner sleeve 111. The inner sleeve 111 has a docking groove 112 and a mounting groove 113 at its two ends, respectively. A magnetic suction element 114 is fixed to the inner side wall of the docking groove 112. An eccentric element 115 is movably installed inside the mounting groove 113. A bearing is fixed between the eccentric element 115 and the mounting groove 113. A drug roll tray 116 is fixed to the side wall of the eccentric element 115. The eccentric element 115 can ensure that the drug roll tray 116 is in a horizontal state when the detection tube 9 rotates. After the drug roll tray 116 is mounted on the eccentric element 115, the center of gravity is located below the center of the circle and does not rotate synchronously with the detection tube 9.

[0025] The docking part 4 docks with the docking groove 112, and the electromagnet 5 is energized and attracted and fixed between itself and the magnetic attracting part 114.

[0026] A filter screen 121 is fixed inside the port cover 12 for filtering air.

[0027] A stepper motor 20 is fixed on the side wall of the factory building away from the conveyor 2, and the output end of the stepper motor 20 is fixedly connected to the mounting pipe 7.

[0028] One end of the port cap 12 extends into the detection tube 9 and is sealed together with the sleeve tube 10.

[0029] Multiple support plates 21 are fixed on the surface of the conveyor 2. The explosive cartridge tray 116 is placed on the upper surface of the support plate 21. Explosive cartridges are placed inside the explosive cartridge tray 116. The explosive cartridge tray 116 is used to store explosive cartridges. When the vacuum detection finds a large hole on the surface of the explosive cartridge, the emulsion explosive will flow out. At this time, the explosive cartridge tray 116 can receive the flowing emulsion explosive.

[0030] When using this device:

[0031] Examples, References Figure 1 In this embodiment, there are two sets of conveyors 2 and two telescopic cylinders 3. The upper conveyor 2 is set as the place for qualified products and the lower conveyor 2 is set as the place for unqualified products. The upper telescopic cylinder 3 is aligned with the topmost detection tube 9 and the lower telescopic cylinder 3 is aligned with the bottommost detection tube 9. The stepper motor 20 is set to drive the entire machine compartment 8 to rotate clockwise by 20° at certain intervals. A total of eighteen detection tubes 9 are fixed on the surface of the machine compartment 8.

[0032] Undetected pill rolls are placed in the pill roll tray 116 of the pill roll placement assembly 11. The pill roll placement assembly 11 is placed on the support plate 21 on the surface of the lower conveyor 2. The entire device is operated by programming the terminal controller. The lower conveyor 2 brings the pill roll placement assembly 11 to the position of the lower telescopic cylinder 3. The moving end of the telescopic cylinder 3 extends, so that the docking part 4 aligns with the docking groove 112 of the inner sleeve 111. The electromagnet 5 contacts the magnetic suction part 114. The lower telescopic cylinder 3 extends and pushes the entire pill roll placement assembly 11 into the sleeve tube 10. 3. Retract, telescopic cylinder 3 separates from the medicine roll placement assembly 11; then the sleeve tube 10 is driven to rotate 180° around the center line of the machine compartment 8 to the top. During the process, the inside of the detection tube 9 where the sleeve tube 10 is placed is vacuumed. The inside of the detection tube 9 in the 0°~90° range is vacuumed, the first electric control valve 13 is opened, and the second electric control valve 19 is closed. The inside of the detection tube 9 in the 90°~180° range is filled with air, the first electric control valve 13 is closed, and the second electric control valve 19 is opened. After the test is completed, there are two situations: the medicine roll is undamaged and the medicine roll is damaged.

[0033] When the medicine roll is found to be undamaged, the upper telescopic cylinder 3 extends, causing the docking piece 4 to align with the docking groove 112 of the inner sleeve 111. The electromagnet 5 contacts the magnetic suction piece 114, and energizing the electromagnet 5 causes it to adhere to the magnetic suction piece 114. The moving end of the upper telescopic cylinder 3 is then fixed to the medicine roll placement assembly 11. The telescopic cylinder 3 retracts, pulling the medicine roll placement assembly 11 out of the sleeve tube 10 and guiding it onto the surface of the support plate 21 of the upper conveyor 2. Then, the electromagnet 5 is de-energized, and the moving end of the telescopic cylinder 3 retracts from the medicine roll placement assembly 11. The roll placement assembly 11 separates and retracts to one end. Finally, the transmission belt of the upper conveyor 2 drives the support plate 21 to move one unit distance, making room for another roll placement assembly 11 containing a roll. The detection tube 9 of the roll placement assembly 11 is removed and rotated 180° back to the initial bottom position. The transmission belt of the lower conveyor 2 drives the support plate 21 to move one unit distance. The lower telescopic cylinder 3 pushes the next roll detection assembly containing an undetected roll on the surface of the lower conveyor 2 into the detection tube 9, and the detection operation is repeated.

[0034] When a damaged pill roll is detected, the detection tube 9 containing the damaged pill roll rotates 180° back to its initial bottom position. The lower telescopic cylinder 3 extends, allowing the docking piece 4 to align with the docking groove 112 of the inner sleeve 111. The electromagnet 5 contacts the magnetic suction piece 114, and the electromagnet 5 is energized, causing it to adhere to the magnetic suction piece 114. The moving end of the lower telescopic cylinder 3 is fixed to the pill roll placement assembly 11. The telescopic cylinder 3 retracts, pulling the pill roll placement assembly 11 out of the sleeve tube 10 and guiding it onto the surface of the support plate 21 of the lower conveyor 2. Then, the electromagnet 5 is de-energized, the moving end of the telescopic cylinder 3 separates from the pill roll placement assembly 11 and retracts a distance. The transmission belt of the lower conveyor 2 moves the support plate 21 a unit distance, using the lower telescopic cylinder 3 to push the next pill roll detection assembly containing an undetected pill roll onto the surface of the lower conveyor 2 into the detection tube 9, thus repeating the detection operation.

[0035] The medicine rolls are inspected according to the above inspection method, and unqualified products are removed. Damaged medicine rolls are sorted and collected at the end of the lower conveyor 2, while undamaged medicine rolls are sorted and collected at the end of the upper conveyor 2.
