Description

Technical Field

[0001] The utility model belongs to fireworks charging equipment, in particular to a kind of bead-discharging 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 the prior art, production is manually operated by manually filling quantitative molds. It is necessary to provide a new type of fully automated equipment to solve the manual operation, separate people and drugs, ensure personnel safety, and improve production efficiency.

[0003] At present, there is a powder pressing machine for bead-throwing fireworks on the market, which is mainly used for pressing powder for bead-throwing fireworks. The filling part is still manually filled with quantitative molds, and the operators are still in direct contact with the medicine during the operation, which poses certain safety hazards to the workers in the fireworks production. The powder filling equipment for bead-throwing fireworks is used for quantitative filling of the medicine for bead-throwing fireworks. It cooperates with the powder pressing machine for bead-throwing fireworks to realize the mechanized and automatic production of the production process of bead-throwing fireworks, ensure the isolation of people and medicine, and ensure the safety of operators.

[0004] The storage hoppers of existing bead-spitting fireworks charging machines on the market are generally made of rigid materials, and most of the materials are discharged by vibration. The bright beads are prone to collision in the hopper. Frequent collision and friction can easily cause damage and dust to the powder particles. The increase in the rate of irregular particles affects the final material collection accuracy. The large amount of dust generated can easily lead to the risk of high combustion and high explosion.

[0051] See Fig.14 , Fig.15 and Fig.16 The propellant unloading mechanism 3 includes a base plate 301 mounted on the frame 1, a hopper 302 in a regular hexagon shape fixed to the base plate 301 by a flange ring 306, a rake claw 305 arranged on the base plate 301 and driven by a cylinder 303 and located in the hopper 302 and capable of raking the medicine back and forth, an upper guide plate 307 fixed on the base plate 301 and located at the bottom of the hopper 302, a unloading material distribution plate 310 fixed on the base plate 301 and located at the bottom of the upper guide plate 307 and driven by a push-pull cylinder 308 and capable of moving back and forth relative to the upper guide plate 307, and a 01 is provided with a lower material guide plate 311 located at the bottom of the lower material distribution tray 310, and a vibrating cylinder 309 fixed on the bottom plate 301; the upper material guide plate 307 and the lower material distribution tray 310 are respectively provided with rounded rectangular holes d and d' that are evenly distributed in a regular hexagon and can correspond one to one; the lower material guide plate 311 is provided with conical holes e distributed in a regular hexagon that are staggered with the rounded rectangular holes d of the upper material guide plate 307 and can correspond one to one with the rounded rectangular holes d' of the lower material distribution tray 310; the conical holes e on the lower material guide plate 311 can correspond one to one with the material holes c of the material holding tray 201.

[0052] The rake claw 305 includes two linear bearings 304 passing through the hopper 302 at both ends and a plurality of rake heads 3051 of different lengths welded on the two linear bearings 304. One end of the linear bearing 304 is connected to a cylinder 303 fixed on the bottom plate 301 at one side of the hopper 302. The cylinder 303 drives the linear bearing 304 to move back and forth to drive the rake claw 302 to rake the medicine in the hopper 302 back and forth. The four top corners and bottoms of the unloading and distributing plate 310 are installed on two guide shafts 312 through bearing plates 314. The guide shafts 312 are fixed on the bottom plate 301 through bearing seats 313 so that The rounded rectangular hole d′ on the lower material distribution tray 310 corresponds one to one with the rounded rectangular hole d on the upper material guide plate 307. The volume of the rounded rectangular hole d′ on the lower material distribution tray 310 is controlled by designing the size of the rounded rectangular hole d′ and the thickness of the plate to achieve a constant volume and quantity of the medicine; the lower material guide plate 311 is fixed to the bottom of the base plate 301 by bolt columns, the push-pull cylinder 308 is fixed to the bottom of the base plate 301 by bolts and connected to one side of the lower material distribution tray 310, and the vibration cylinder 309 is fixed to the bottom of the base plate 301 by bolts and is located on the other side of the lower material distribution tray 310 and corresponds to the push-pull cylinder 308.

[0053] When the propellant discharge mechanism 3 is working, the rounded rectangular hole d' of the discharge material distribution plate 310 corresponds to the rounded rectangular hole d of the upper material guide plate 307 one by one, and the medicine in the hopper 302 falls into the rounded rectangular hole d' of the discharge material distribution plate 310, and is filled up under the raking of the rake claw 305. Then, the push-pull cylinder 308 pushes the discharge material distribution plate 310 to move along the guide shaft 312, and the rounded rectangular hole d' of the discharge material distribution plate 310 corresponds to the upper material guide plate 307. The rounded rectangular hole d of the plate 307 is offset and aligned with the circular conical hole e of the lower material guide plate 311. The material distribution tray 310 is against the vibrating cylinder 309, and the vibrating cylinder 309 vibrates. The medicine in the material distribution tray 310 falls into the material hole c of the material containing tray 201 of the material transfer and filling mechanism 2 through the circular conical hole e of the lower material guide plate 311. The material removal is completed, the vibrating cylinder 309 stops operating, and the push-pull cylinder 308 pulls the material distribution tray 310 back to its original position.

[0054] The gold powder feeding mechanism 4 and the propellant feeding mechanism 3 are collectively referred to as feeding mechanisms, and their structures and movement principles are consistent.

[0055] Working principle:

[0056] like Figure 1As shown, when the utility model is working, the material can be taken according to the need of charging the fireworks product. The motor 204 of the material conveying and filling mechanism 2 drives the material tray 201 and the material guide tray 202 to be transported to the lower part of the propellant discharge mechanism 3, the gold powder discharge mechanism 4 or the bright bead quantitative charging and discharging mechanism 5 in sequence through the annular toothed belt strip 206, and one of the propellant, gold powder or bright bead agents is loaded into the material tray 201 to complete the material taking, and then the annular toothed belt strip 206 drives the material tray 201 to be returned for transportation and connected with the bead-discharging fireworks charge-making equipment to carry out the next process.

[0057] When the bright bead quantitative filling and unloading mechanism 5 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 slider 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 transferred by the material transfer and filling mechanism 2. After completing the material taking process, 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 during the next material taking process.

[0058] See Fig.11 —— Fig.13When the material tray 201 and the material guide tray 202 return, when the grooves b' on both sides of the front end of the material guide tray 202 contact and match with the vertical rods (not shown) in the medicine-building equipment, the material guide tray 202 stops moving forward and compresses the top column spring 211, and the material tray 201 continues to move forward until its front end groove b also contacts and matches with the vertical rods in the medicine-building equipment. At this time, the material guide tray 202 is aligned with the material tray 201, and the material hole c of the material tray 201 and the material hole c' of the material guide tray 202 are aligned. Correspondingly, the medicine in the material hole c of the material receiving tray 201 falls into the bead-discharging fireworks paper tube (not shown) in the medicine-making equipment through the material hole c′ of the material guide tray 202, completing the filling of the medicine; then the material receiving tray 201 and the material guide tray 202 withdraw from the medicine-making equipment driven by the annular toothed belt strip 206, and the top column spring 211 is released to reset the top column material guide tray 202, so that its material hole forms an initial misaligned state with the material hole of the material receiving tray 201, and the material receiving tray 201 returns to the starting position.

[0059] The material holding tray 201 and the material guiding tray 202 in the present invention may not be provided with the grooves b and the grooves b'. Since the material guiding tray 202 is misaligned with the material holding tray 201, when they return, they can be forced to align as long as they are blocked by an object set in the medicine-making equipment, so that the material holes c of the material holding tray 201 and the material holes c' of the material guiding tray 202 correspond one to one.
