[0053] like Figures 4 to 8 As shown, the delayed-release tube loading device according to an embodiment of the present invention includes:

[0054] The first transfer tray 200 is used to vertically place the delay tube 1 and make the first chamber 11 of the delay tube 1 face upward.

[0055] The dosing sleeve 640 can be placed on the first transfer tray 200 and the delay tube 1 is placed inside the dosing sleeve 640. The dosing sleeve 640 is provided with a vertical guide tube 641. The outlet of the guide tube 641 can be inserted into the first chamber 11 and aligned with the opening of the first chamber 11.

[0056] The primary charge device 610 can add a fixed amount of gunpowder from the feed port of the feed pipe 641 and into the first chamber 11.

[0057] The primary pressing device 620 presses the gunpowder in the feed pipe 641 into the first chamber 11 and compresses the gunpowder in the first chamber 11 so that the surface of the gunpowder in the first chamber 11 is flush with the opening of the first chamber 11.

[0058] The sleeve picking and placing device 630 is used to cover the charging sleeve 640 on the first transfer tray 200 before the first chamber 11 is filled with gunpowder, and to remove the charging sleeve 640 from the first transfer tray after the first chamber 11 is filled with gunpowder.

[0059] like Figure 4 and Figure 5 As shown, when pressing gunpowder into the first chamber 11 of the delay tube 1, the feeding system 500 places the delay tube 1 on the first transfer tray 200, ensuring that the first chamber 11 of the delay tube 1 faces upwards. The feeding system 500 mainly includes a delay tube hopper, a vibrating screening channel, and a gripping robot. The delay tube 1 flows out of the delay tube hopper, passes through the vibrating screening channel for screening, obtaining delay tubes with the first chamber 11 facing upwards, and is then gripped and placed on the first transfer tray 200 by the gripping robot.

[0060] Subsequently, as Figure 6 As shown, the sleeve loading and unloading device 630 first mounts the gunpowder sleeve 640 onto the receiving platform 210, ensuring that the outlet of the feed tube 641 can be inserted into the first chamber 11 and aligned with the opening of the first chamber 11. The primary gunpowder loading device 610 loads a measured amount of gunpowder through the inlet of the feed tube 641. The gunpowder flows along the feed tube 641 into the first chamber 11. Since the gunpowder is not yet compacted, it will be present in both the first chamber 11 and the feed tube 641.

[0061] like Figure 8 As shown, the gunpowder in the feed tube 641 is then pressed into the first chamber 11 by the pressurizing device 620, and the gunpowder in the first chamber 11 is compressed so that the surface of the gunpowder in the first chamber 11 is flush with the opening of the first chamber 11. After the pressurization is completed, the sleeve loading device 630 removes the loading sleeve 640 from the receiving platform 210 and places it back on the first transfer tray 200 for the next loading. The pressurization of gunpowder into the first chamber 11 of the delay tube 1 is completed.

[0062] In some embodiments of the present invention, a receiving platform 210 is provided on the first transfer tray 200, the diameter of the dosing sleeve 640 matches the diameter of the receiving platform 210, the dosing sleeve 640 can be fitted onto the receiving platform 210, a first support column 220 is vertically provided in the middle of the receiving platform 210, the diameter of the first support column 220 matches the inner diameter of the second chamber 12 of the delay tube 1, and the delay tube 1 is installed on the first support column 220 through the second chamber 12.

[0063] like Figure 6 and Figure 8 As shown, when the delay tube 1 is installed on the first transfer tray 200, the second chamber 12 faces downwards and is fitted onto the first support column 220. At the same time, the first support column 220 will seal the outlet below the first chamber 11 to prevent the gunpowder entering the first chamber 11 from flowing out, ensuring that after the gunpowder in the first chamber 11 is compressed, the gunpowder in the first chamber 11 will be squeezed into shape and remain in the first chamber 11.

[0064] In some embodiments of the present invention, the primary pressing device 620 includes a first lifting device 621 and a first pressing shaft 622. The first pressing shaft 622 is arranged vertically and is connected to the first lifting device 621. The lower end of the first pressing shaft 622 can extend from the guide tube 641 to the first chamber 11 and is flush with the opening of the first chamber 11.

[0065] Combination Figure 7 As shown, in this embodiment, when the first chamber 11 is pressurized with gunpowder, the lower end of the first pressing shaft 622 can extend from the guide tube 641 into the first chamber 11 under the drive of the first lifting device 621, until it descends to be flush with the opening of the first chamber 11, thereby pressing the gunpowder in the guide tube 641 into the first chamber 11 and pressing the gunpowder in the first chamber 11 tightly, so that the surface of the gunpowder in the first chamber 11 is flush with the opening of the first chamber 11.

[0066] In some embodiments of the present invention, a first transfer conveyor line 100 is also included. The first transfer conveyor line 100 has a first head end 110 and a first tail end 120. The first transfer conveyor line 100 is provided with a primary loading station and a primary pressing station in sequence from the first head end 110 to the first tail end 120. A first transfer tray 200 is disposed on the first transfer conveyor line 100 and can flow along the first transfer conveyor line 100. A primary dosing device 610 is disposed at the primary loading station and a primary pressing device 620 is disposed at the primary pressing station.

[0067] like Figure 4 and Figure 5 As shown, by setting up a first transfer conveyor line 100, the first transfer tray 200 carries the delay tube 1 along the first transfer conveyor line 100. At the first loading station, the first chamber 11 is filled with medicine by the first adding device 610; at the first pressing station, the first chamber 11 is pressed with medicine by the first pressing device 620. Through this assembly line operation, different stations perform different operations, improving production efficiency.

[0068] In some embodiments of the present invention, a first explosion-proof box 623 and a first transfer robot 624 are also included. The first explosion-proof box 623 is provided with a first pressing chamber. The first transfer robot 624 is used to transfer the first transfer pallet 200 between the first transfer conveyor line 100 and the first pressing chamber. A primary pressing device 620 is provided on the first explosion-proof box 623.

[0069] Gunpowder is a dangerous and explosive substance, especially during the pressing process, which generates significant impact pressure and poses a considerable risk of explosion.

[0070] Combination Figure 7 As shown, in this embodiment, by setting up a first explosion-proof box 623 and a first transfer robot 624, during the pressing process, the first transfer robot 624 transfers the first transfer tray 200 to the first pressing chamber, and then the first lifting device 621 and the first pressing shaft 622 press the delay tube 1 that has entered the first pressing chamber. After the pressing is completed, the first transfer robot 624 removes the first transfer tray 200 from the first pressing chamber and puts it back on the first transfer conveyor line 100, thereby improving safe production.

[0071] In some embodiments of the present invention, the feed inlet of the feed tube 641 is an inverted conical opening. For example... Figure 7 and Figure 8 As shown, by setting the feed inlet of the feed pipe 641 to an inverted conical shape, it is easier for the primary dosing device 610 to add gunpowder into the feed pipe 641.

[0072] In some embodiments of the present invention, a secondary charging and pressing system is also included. The secondary charging and pressing system is used to charge a certain amount of gunpowder into the second chamber 12 of the delay tube 1, press the gunpowder entering the second chamber 12, and form holes in the gunpowder layer in the second chamber 12.

[0073] After the gunpowder is loaded into the first chamber 11, the present invention further loads a fixed amount of gunpowder into the second chamber 12 of the delay tube 1 by setting up the first chamber 11, and then compresses the gunpowder entering the second chamber 12. Thus, the gunpowder loading is completed in both the first chamber 11 and the second chamber 12 of the entire delay tube 1.

[0074] In a further embodiment of the present invention, the secondary loading and pressing system includes a transposition system 1000, a second transfer conveyor line 300, a second transfer tray 400, a forming rod 430, a secondary loading device 900, and a secondary pressing device 1200.

[0075] The second transfer conveyor line 300 has a second beginning end 310 and a second end end 320. The second transfer conveyor line 300 is provided with a secondary loading station and a secondary pressing station from the second beginning end 310 to the second end end 320.

[0076] The second transfer tray 400 is set on the second transfer conveyor line 300 and can flow along the second transfer conveyor line 300. The second transfer tray 400 is provided with a charging mold 410. The charging mold 410 includes an outer sleeve 411, an inner sleeve 412 and a return spring 413. The return spring 413 is set inside the outer sleeve 411. The inner sleeve 412 is set inside the outer sleeve 411 and presses against the upper end of the return spring 413. The inner sleeve 412 is provided with a gunpowder holding pipe 420.

[0077] The forming rod 430 includes a second support column 431 and a forming column 432. The second support column 431 is fixed inside the outer sleeve 411. The upper end of the second support column 431 passes through the bottom of the gunpowder holding pipe 420 and extends into the gunpowder holding pipe 420. The diameter of the second support column 431 matches the diameter of the gunpowder holding pipe 420. The inner sleeve 412 can move up and down along the second support column 431. The forming column 432 is arranged along the axis of the second support column 431, and its upper end extends out from the upper end face of the forming column 432.

[0078] The transfer system 1000 is used to transfer the delayed tube 1, after pressing, on the first transfer tray 200 to the second transfer tray 400;

[0079] When the secondary charging device 900 and the second transfer tray 400 are transferred to the secondary charging station, the secondary charging device 900 will load a certain amount of gunpowder into the gunpowder holding pipe 420.

[0080] When the delay tube 1 is transferred to the secondary pressing station by the second transfer tray 400, the secondary pressing device 1200 applies downward pressure to the delay tube 1.

[0081] like Figure 4 , Figure 5 , Figure 9 , Figure 10 , Figure 11 As shown, before the delay tube 1 is transferred to the second transfer tray 400, the second transfer tray 400 is first transferred to the secondary charging station, and the secondary charging device 900 loads a certain amount of gunpowder into the gunpowder holding pipe 420.

[0082] After the gunpowder is loaded into the first chamber 11 of the delay tube 1, the transfer system 1000 transfers the delayed tube 1, which has been loaded with gunpowder on the first transfer tray 200, to the second transfer tray 400.

[0083] When the delay tube 1 is transferred to the secondary pressing station by the second transfer tray 400, the secondary pressing device 1200 moves downward, applying downward pressure to the delay tube 1. The inner sleeve 412 is subjected to force, forcing the inner sleeve 412 to move downward, and the return spring 413 is compressed by the pressure.

[0084] At this time, the second support column 431 and the forming column 432 will not move. Therefore, during the downward movement of the delay tube 1, the gunpowder in the gunpowder container pipe 420 will be pressed into the second chamber 12 under the action of the second support column 431 until the gunpowder entering the second chamber 12 is compressed.

[0085] As the gunpowder is pressed into the second chamber 12, due to the presence of the forming column 432, a hole matching the forming column 432 will be generated in the center of the gunpowder after it is compressed.

[0086] Afterwards, the secondary pressing device 1200 releases its downward pressure, and the inner sleeve 412 moves upward under the restoring force of the return spring 413, causing the forming column 432 to disengage from the second chamber 12. The inner sleeve 412 returns to its initial position, preparing for the next round of loading and pressing. Then, the delay tube 1 continues to flow along the second transfer tray 400 on the second transfer conveyor line 300, and is removed after reaching the unloading station.

[0087] In some embodiments of the present invention, the secondary pressing device 1200 includes a second lifting device 1210 and a second pressing shaft 1220. The second pressing shaft 1220 is vertically arranged and is connected to the second lifting device 1210. The second pressing shaft 1220 can apply downward pressure to the delay tube 1 under the drive of the second lifting device 1210.

[0088] Combination Figures 9 to 11As shown, when pressing the second chamber 12 of the delay tube 1, the second pressing shaft 1220, under the action of the second lifting device 1210, applies downward pressure to the delay tube 1, forcing the inner sleeve 412 to move downward, and the return spring 413 is compressed by the pressure. After pressing is completed, the second pressing shaft 1220, under the action of the second lifting device 1210, moves upward and returns to the initial position.

[0089] In a further embodiment of the present invention, a second explosion-proof box 700 and a second transfer robot 800 are also included. The second explosion-proof box 700 is provided with a second pressing chamber. The second transfer robot 800 is used to transfer the second transfer pallet 400 between the second transfer conveyor line 300 and the second pressing chamber. The secondary pressing device 1200 is disposed on the second explosion-proof box 700.

[0090] During the compression of the second chamber 12 of the delay tube 1, the second transfer robot 800 transfers the second transfer tray 400 containing the delay tube 1 to the second explosion-proof box 700 for compression, avoiding the risk of explosion during the compression process. After compression is completed, the second transfer robot 800 then transfers the second transfer tray 400 containing the delay tube 1 to the second transfer conveyor line 300.
