Description

Technical Field

[0001] The utility model belongs to fireworks charging equipment, in particular to a quantitative filling and unloading mechanism of fireworks charging equipment. Background Art

[0002] Bead-spitting fireworks are a type of handheld fireworks. During production, propellant, gold powder, bright beads and other drugs are sequentially loaded into the firework paper tube. In order to change the traditional method of manually filling drugs with quantitative molds, fireworks charging equipment has appeared on the market for automatic charging. However, the storage hopper of this charging equipment is generally made of rigid materials such as metal, and most of the materials are discharged by vibration. Bright beads are prone to collision in the storage hopper. Frequent collision and friction can easily cause damage and dust to the drug particles. The increase in the rate of irregular particles affects the final material collection accuracy; the large amount of dust generated is prone to the risk of high combustion and high explosion.

[0029] Working principle:

[0030] like Figure 1 As shown, the propellant discharge mechanism 3 and the gold powder discharge mechanism 4 in the bead-spitting fireworks charge equipment are both provided with a distribution mechanism similar to the distribution plate, upper material guide plate and lower material guide plate of the quantitative filling discharge mechanism 5. When the equipment is working, the material conveying and filling mechanism 2 can take materials according to the needs of the fireworks product charge, and transport the material tray 201 to the propellant discharge mechanism 3, the gold powder discharge mechanism 4 or the lower part of the quantitative filling discharge mechanism 5, align with their distribution mechanisms, and load one of the drugs such as propellant, gold powder or bright beads into the material tray 201 to complete the material taking, and then return the material tray 201 for transportation to connect with the bead-spitting fireworks charge equipment to carry out the next process.

[0031] When the quantitative filling and unloading mechanism 5 of the utility model is working, Fig. 9 As shown, the lifting cylinder 5102 drives the upper component 52 and the sweeping component 54 to be lifted upward as a whole through the linear optical axis 5204 along the linear bearing base 5104, and the cloth bag 5203 is pulled up into a funnel shape, and the drug beads a in the cloth bag 5203 roll toward the middle and accumulate on the distribution plate 5301, filling the quantitative hole 5309; Fig.10 As shown, the lifting cylinder 5102 drives the upper component 52 and the sweeping component 54 to descend to the position where the roller brush 5402 is flush with the distribution plate 5301. At this time, the cloth bag 5203 droops around the distribution plate 5301 to form a bag-shaped portion, and the slide cylinder 5403 drives the roller brush 5402 to move back and forth through the slide 5409. With the cooperation of the synchronous wheel 5404 and the toothed belt strip 5405, the roller brush 5402 forms a forward and reverse rotation. After one round trip, the roller brush 5402 sweeps the bright beads a accumulated on the distribution plate 5301 out of the distribution plate 5301, and only the bright beads a in the quantitative holes 5309 of the distribution plate 5301 are retained, thereby ensuring the quantitative amount of medicine loaded each time. The other bright beads a fall into the bag-shaped portion of the cloth bag 5203, completing the material taking process. Next, a material guide cylinder 5304 pushes the upper material guide plate 5305 to move, so that the upper cylindrical conduit 5310 of the upper material guide plate 5305 is aligned one by one with the quantitative holes 5309 of the material distribution plate 5301. At this time, the lower cylindrical conduit 5311 on the lower material guide plate 5306 and the upper cylindrical conduit 5310 of the upper material guide plate 5305 are aligned one by one with the quantitative holes 5309 of the material distribution plate 5301, and the bright beads a fall from the material distribution plate 5301 through the upper material guide plate 5305 into the lower material distribution plate 5301. The upper material guide plate 5305 finally falls into the material hole of the material containing plate 201 below the lower material guide plate 5305, which is transmitted by the material transfer and filling mechanism 2. After the loading process is completed, another material guide cylinder 5304 pushes the upper material guide plate 5305 to move back to its original position, so that the upper cylindrical guide tube 5310 of the upper material guide plate 5305 is misaligned with the quantitative hole 5309 of the material distribution plate 5301, so that the bright beads a can continue to be filled in the quantitative hole 5309 in the next material taking process.
