[0039] How it works

[0040] 1. Feeding: See Figure 1 — Figure 3 When the drug batching and conveying device 2 is working, the four kinds of gunpowder are first poured into the hoppers 2011 of the four groups of drug mixing devices 201 respectively. The gunpowder in the hoppers 2011 of each drug mixing device 201 is stirred by the stirring shaft 2014 in the discharge barrel 2012 (to prevent the gunpowder from arching) and then sent to the vibrating screen 202 box 2021 by the screw conveyor. The vibrating box 2021 uses the screen to evenly drop the gunpowder on the conveyor belt 2031 of the drug conveying device 203. Since the feed ports 2022 of the box 2021 are arranged in a line, when the conveyor belt 2031 passes through each feed port 2022 in turn, the gunpowder dropped from the first feed port 2022 forms a first gunpowder layer on the conveyor belt 2031, and the gunpowder dropped from the subsequent feed ports 2022 respectively falls on the gunpowder layer dropped from the previous feed port 2022, and finally four gunpowder layers are formed on the conveyor belt 2031.

[0041] 2. Mixing: See Figure 4The gunpowder falls from the conveyor belt 2031 of the drug batching and conveying device 2 into the mixing barrel 301 of the drug mixing device 3 through the hopper 2032 and the feed port 302. The four types of gunpowder are evenly mixed after vibration, multi-layer guide plate guidance and screen screening to form material b, which falls into the equalizing bin 403 of the drug charging quantitative device 4 through the discharge port 303.

[0042] 3. Charge: First, make several single paper inner tubes into hexagonal empty paper tube cakes a. The empty paper tube cakes a to be charged are transported by the feeding and conveying unit 102 in the firework paper tube cake conveying device 1 to the firework paper tube cake rotating charge receiving device 5. The charge quantitative device 4 cooperates with the firework paper tube cake rotating charge receiving device 5 to quantitatively fill the mixed material b into each inner tube of the empty paper tube cake a. Figure 4 — Fig.11 The function of the charging quantitative device 4 is to quantitatively load the material b into the inner tube of the empty paper tube cake a. The working principle of the quantitative charging is as follows: in the initial state, the quantitative hole 40261 on the moving template 4026 in the quantitative template assembly 402 is aligned with the quantitative hole 40211 on the upper template 4021, and the other non-porous parts close the quantitative hole 40241 on the lower template 4024. After the material b from the mixing device 3 enters the equalizing bin 403, the equalizer 401 rotates, and the rake nails 4013 under the scraper 4012 are used to rake the material b evenly and enter the quantitative hole 40211 on the upper template 4021 and the metering hole 40261 of the movable template 4026 until it is filled, and then the movable template 4026 moves to align the metering hole 40261 on it with the metering hole 40241 on the lower template 4024, and the non-porous part blocks the metering hole 40211 of the upper template 4021, and the material b in the metering hole 40261 of the movable template 4026 falls through the metering hole 40241 on the lower template 4024, and enters the inner tube of the empty paper tube cake a through the charging disk 503 of the rotating medicine receiving device 5 of the firecracker paper tube cake, completing a quantitative charging process of the empty paper tube cake a.

[0043] If the speed at which material b falls into the equalizing bin 403 exceeds the quantitative charging speed, it will accumulate in the equalizing bin 403. When the height of the accumulated material b reaches the set value and touches the detection component 407, the detection component 407 sends a detection signal to the control device, and the control device issues an instruction to control the drug dosing and conveying device 2 to suspend conveying material b to the quantitative charging device 4. After the material b in the equalizing bin 403 returns to normal, the drug dosing and conveying device 2 continues to work.

[0044] See also Figure 4 —— Figure 5 , Fig.10 —— Fig.11When the firecracker paper tube cake rotating medicine receiving device 5 is working, at the feeding station, the workpiece support plate 502 of the workpiece tray mechanism is located in the middle area of ​​one side of the guide rail 509 through the guide wheel 508 and the bottom of the guide rail 509, and is in the low position stage. The empty paper tube cake a to be loaded is pushed into the limiting edge 5021 of the workpiece support plate 502 of the workpiece tray mechanism by the feeding pushing device 7. The workpiece support plate 502 carries the empty paper tube cake a and rotates synchronously with the main shaft 512 together with the charging disc 503. When it moves to the charging station, the guide wheel 508 of the workpiece support plate 502 enters the inclined surface 5091 at the rear end of the guide rail 509 and moves out of the guide rail 509. Under the action of the spring 510, the workpiece support plate 502 performs an upward movement and is in the high position stage, so that the empty paper tube cake a on it is close to the charging disc 503, and each inner cylinder in the empty paper tube cake a and the charging disc 503 are in contact with each other. The material holes 5031 on the charging disc 503 correspond one to one, and the material holes 5031 on the charging disc 503 just correspond to the quantitative holes 40241 on the lower template 4024 of the charging quantitative device 4. At this time, the firecracker paper tube cake rotating medicine receiving device 5 stops rotating, and the charging is completed through the charging quantitative device 4; then the firecracker paper tube cake rotating medicine receiving device 5 starts to rotate again, and the workpiece support plate 502 carries the loaded paper tube cake a′ and enters the guide rail 509 from the inclined surface 5091 at the front end of the guide rail 509 to make a downward movement and enter the middle area on the other side of the guide rail 509 and is in a low position stage, so that the paper tube cake a′ is separated from the charging disc 503 until the discharging station, and the discharging pushing device 8 pushes the paper tube cake a′ loaded with material b to the discharging conveying unit 103 of the firecracker paper tube cake conveying device 1, and transports it to the outside of the charging workshop and enters the next process workshop for paper tube sealing.

[0045] Since the charging disc 503 is provided with three workpiece support plates 502 of the workpiece tray mechanism arranged according to the workstations, when the discharging station is discharging materials, the feeding station is feeding materials at the same time, and the operation is repeated continuously. This feature of the present invention can greatly improve the quality and efficiency of charging firecracker paper tube cakes.
