[0029] Working principle:
[0030] As Figure 1 shown, when the pellet - type fireworks charging equipment is working, the material transfer and loading mechanism 2 can take materials according to the needs of fireworks product charging, transport the material - holding tray to the lower part of the propellant feeding mechanism 3 or the bright pellet quantitative filling and feeding mechanism 4, align it with their quantitative filling components, load one of the propellants such as propellant, gold powder or bright pellets into the material - holding tray to complete material taking, and then return the material - holding tray for transportation to connect with the pellet - type fireworks building - powder equipment for the next process.
[0031] See Figure 1 —— Figure 8, when the propellant feeding mechanism 3 is working, the lifting cylinder 3102 drives the upper layer assembly 32 and the sweeping component 34 to be lifted upward along the linear optical axis 3204 along the linear bearing base 3104 as a whole. The cloth bag 3203 is stretched into a funnel shape, and the granular agent in the cloth bag 3203 rolls towards the middle and accumulates on the dosing plate 3301, filling the dosing holes 3304; the lifting cylinder 3102 drives the upper layer assembly 32 and the sweeping component 34 to descend to a position where the roller brush 3402 is flush with the upper surface of the dosing plate 3301. At this time, the cloth bag 3203 droops around the dosing plate 3301 to form a pocket part. The sliding table cylinder 3403 drives the roller brush 3402 to move back and forth through the sliding table 3409. Under the cooperation of the synchronous pulley 3404 and the toothed belt strip 3405, the roller brush 3402 rotates forward and backward. For one round trip, the roller brush 3402 sweeps the agent accumulated on the dosing plate 3301 out of the dosing plate 3301, only leaving the agent in the dosing holes 3304 of the dosing plate 3301, ensuring the quantitative dosing of the agent for each charge. Other agents then fall into the pocket part of the cloth bag 3203, completing the material taking process. Next, after the cylinder 3501 contracts and pulls the draw plate 3506 and the open belt 3503 to move into place, the dosing holes 3304 of the dosing plate 3301 are aligned with the guide pipes 3306 of the lower layer guide plate 3305 one by one, and the agent finally falls into the material holes of the material receiving tray 201 conveyed by the material transfer and loading mechanism 2 to the lower part of the lower layer guide plate 3305, completing the loading process. Then, the cylinder 3501 pushes the draw plate 3506 and the open belt 3503 to move back to the original position where the dosing holes 3304 of the dosing plate 3301 are isolated from the first round holes 3510 on the draw plate 3506, so that the powder agent can continue to be filled in the dosing holes 3304 during the next material taking process; since the front end a of the open belt 3503 is fixed on the front cross bar 3504, when it moves with the draw plate 3506, the part without the second round hole 3511 gradually covers the bottom of the dosing plate 3301, and this part does not displace relative to the dosing plate 3301, which can avoid the safety problem of the agent catching fire caused by the friction between the draw plate 3506 and the dosing plate 3301 during the movement; in addition, the part of the open belt 3503 with the second round hole 3511 is located at the bottom of the draw plate 3506 and communicates with some of the first round holes 3510 on the draw plate 3506 at this time, so that the agent powder accumulated between the open belt 3503 and the draw plate 3506 during the operation of the equipment can be discharged smoothly.
