when the blanking system 1300 and the delay tube 1 are transferred to the blanking station along with the second material transferring tray 400, the blanking system 1300 takes the assembled delay tube 1 off the second material transferring tray 400.

In the practice of the present invention, the first transfer line 100 is an endless transfer line, and the first transfer tray 200 can be circulated in the first transfer line 100. Similarly, the second transfer conveyor line 300 is also a circulating transfer line, and the second transfer trays 400 can circulate on the second transfer conveyor line 300.

When the first material transferring tray 200 is in circulation in the first transferring and conveying line 100, the first material transferring tray 200 starts from the first head end 110 of the first transferring and conveying line 100, flows to the first tail end 120, returns to the first head end 110 from the first tail end 120 through a lower channel, and is in reciprocating circulation.

When the first transfer tray 200 starts from the first head end 110 and is transferred to the feeding station, the feeding system 500 places the delay tube 1 on the first transfer tray 200, and makes the first chamber 11 of the delay tube 1 face upward. Wherein, feeding system 500 mainly includes postpone pipe hopper, vibrations screening channel and snatchs manipulator etc.. The delay tube 1 flows out of the delay tube hopper, is screened through the vibration screening channel to obtain the delay tube 1 with the first cavity 11 facing upwards, and then the delay tube 1 is grabbed and placed on the first material transferring tray 200 through the grabbing manipulator. Subsequently, the first transfer tray 200 carries the delay tube 1 to move to the next station.

As shown in fig. 6 to 8, when the delay tube 1 is transported to the powder charging and pressing station along with the first transfer tray 200, the single powder charging and pressing system 600 first charges a certain amount of powder into the first chamber 11, and then presses the powder entering the first chamber 11. The amount of the propellant to be added is determined by the volume of the first chamber 11, and it is necessary to ensure that the surface of the propellant is flush with the mouth of the first chamber 11 after the propellant has been compacted.

During the process of pressing the powder into the first chamber 11, the powder inevitably overflows from the nozzle of the first chamber 11, and an annular powder bulge (i.e. a powder root) is formed at the center of the nozzle of the first chamber 11, so that the whole powder surface is uneven, the quality of the powder surface is unqualified, and the press fitting of the subsequent adjusting plug 2 is also influenced. With reference to fig. 9 to 12, by providing the explosive root cleaning system 700, when the delay tube 1 is transported to the explosive root cleaning station along with the first transfer tray 200, the explosive root cleaning system 700 trims the explosive surface of the first chamber 11, so that the explosive surface of the first chamber 11 is flush with the nozzle of the first chamber 11, and the explosive surface becomes flat.

As shown in fig. 17, the quality detection system 800 is provided to detect the powder bed height and the powder surface quality of the first chamber 11, and determine whether the powder charging amount is acceptable by detecting the powder bed height of the first chamber 11. If the height of the explosive layer is qualified, the addition amount of the explosive is in a qualified range. The method for detecting the quality of the powder surface mainly comprises the step of detecting whether the powder surface has defects such as cracks, pores and the like. If the detection is qualified, the circulation is continued, and if the detection is not qualified, the circulation is sorted out through the selecting device.

While the first transfer conveyor line 100 is in operation, the second transfer conveyor line 300 is also in operation. When the second transfer tray 400 is transferred to the secondary charging station, the secondary charging device 900 charges a fixed amount of powder into the powder containing pipe 420.

Subsequently, when the second material transferring tray 400 is transferred to the transposition station, the transposition system 1000 transfers and inserts the delay tube 1 that is qualified by the quality detection system 800 into the powder containing pipeline 420. The transposition system 1000 mainly clamps the delay tube 1 by the clamping manipulator and transfers the delay tube 1.

After that, when the delay tube 1 is transferred to the adjusting plug mounting station along with the second transfer tray 400, the adjusting plug mounting device 1100 loads the adjusting plug 2 into the third chamber 13 of the delay tube 1. Wherein, adjust stopper installation device 1100 mainly includes and adjust stopper hopper, screening passageway and sucking disc manipulator, adjusts stopper 2 in the stopper hopper and screens through the screening passageway, obtains the regulation stopper 2 of correct orientation, and rethread sucking disc manipulator adsorbs the regulation stopper 2 after will screening and places in the third chamber 13 of delay pipe 1, adjusts stopper 2 this moment and is not compressed tightly in third chamber 13.

When the delay tube 1 is transferred to the secondary pressing station along with the second material transferring tray 400, the secondary pressing device 1200 moves downwards to press the adjusting plug 2, the force applied to the adjusting plug 2 is sequentially transferred to the delay tube 1 and the inner sleeve 412 to force the inner sleeve 412 to move downwards, and the return spring 413 is compressed under the pressure.

At this time, the first support column 431 and the forming column 432 do not move, so that during the descending process of the delay tube 1, the powder in the powder containing pipe 420 is pressed into the second chamber 12 by the first support column 431 until the powder entering the second chamber 12 is compacted.

While the powder is pressed into the second chamber 12, due to the presence of the forming column 432, the powder entering the second chamber 12 will generate a hole in the center thereof matching the forming column 432 after being pressed.

In addition, the powder is pressed into the second chamber 12, and the adjusting plug 2 is also pressed into the third chamber 13 of the delay tube 1, so that the powder pressing of the delay tube 1 is completed.

Subsequently, the secondary medicine-pressing device 1200 is released from the downward pressure, the inner sleeve 412 is moved upward by the restoring force of the return spring 413, and the forming post 432 is released from the second chamber 12. Inner sleeve 412 returns to the initial position in preparation for the next round of charging and pressing. After that, the delay tube 1 continues to circulate along with the second transfer tray 400 in the second transfer conveyor line 300, and is removed after moving to the blanking station.

When the delay tube 1 is transferred to the blanking station along with the second material transferring tray 400, the blanking system 1300 takes the assembled delay tube 1 off the second material transferring tray 400.

In some embodiments of the present invention, the receiving platform 210 is disposed on the first transfer tray 200, the second supporting column 220 is vertically disposed in the middle of the receiving platform 210, the diameter of the second supporting column 220 matches the inner diameter of the second chamber 12, and the delay tube 1 is mounted on the second supporting column 220 through the second chamber 12.

As shown in fig. 6 and 8, when the delay tube 1 is mounted on the first transfer tray 200, the second chamber 12 faces downward and is sleeved on the second support column 220. At the same time, the second prop 220 will seal the outlet below the first chamber 11, preventing the powder entering the first chamber 11 from flowing out, ensuring that after the powder in the first chamber 11 is compacted, the powder in the first chamber 11 will be extruded and stay in the first chamber 11.
