Referring to fig. 1, the present invention provides a firework inner tube machine (not shown) and a stuffing device 10 thereof. Wherein, fireworks inner tube machine includes filler device 10.

The filling device 10 is used for filling the firework inner barrel into the firework outer barrel. Further, the firework inner barrel machine further comprises a feeding device (not shown) and a discharging device (not shown). The feeding device is used for feeding the firework inner barrel to be filled to the filling device 10, and the discharging device is used for transferring the firework outer barrel filled on the filling device 10 to a specified position. Wherein, loading attachment and unloader can be for mechanical grabbing structure, also can be feed mechanism. When the feeding device and the blanking device are feeding mechanisms, the feeding device and the blanking device can respectively comprise a feeding piece, and the feeding piece can be a conveying belt, a plurality of power rollers arranged in parallel and the like.

Referring to fig. 1 again, the filling device 10 in the preferred embodiment of the present invention includes a machine body 100, a feeding mechanism 200, a turning filling mechanism 300 and a detecting mechanism 400.

The feeding mechanism 200, the turning and discharging mechanism and the detecting mechanism 400 are all installed on the machine body 100. Thus, the body 100 mainly plays a role of supporting and connecting. The body 100 has a working surface 110. The working surface 110 is a working area for filling the firework inner cylinder into the firework outer cylinder. When the stuffing device 10 is located in a horizontal plane, the working surface 110 is an upward horizontal plane. The feeding mechanism 200 is used for feeding and distributing the inner firework cylinder; the overturning filling structure is used for transferring and filling the firework inner barrel in the feeding structure into the firework outer barrel on the working surface 110; the detection mechanism 400 is used for detecting the firework inner barrel in the feeding mechanism 200 so as to sort out the empty firework barrel without powder packaging, reduce the probability of filling the empty firework inner barrel into the firework outer barrel, and improve the quality of the processed firework.

The feeding mechanism 200 includes a hopper 210, a material distributing structure 220 having a material distributing groove 221, and a material pushing structure 320. The material distributing structure 220 is disposed at an end of the hopper 210 facing the working surface 110. When the filling device 10 is located on a horizontal plane, the hopper 210 and the material distributing structure 220 are disposed up and down because the working surface 110 is a horizontal plane facing upward. The chute 221 is in communication with the hopper 210. The hopper 210 is used for placing a plurality of firework inner barrels after powder packing.

In actual use, the inner firework cylinder in the hopper 210 falls into the distributing groove 221 under the action of the gravity of the inner firework cylinder. One or more material distribution grooves 221 may be provided. Specifically, in this embodiment, there are a plurality of distributing grooves 221, and the distributing grooves 221 are arranged at intervals in a direction parallel to the working surface 110.

Referring to fig. 2 and 3, in some embodiments, the distributing structure 220 includes a supporting plate 222, a distributing plate 223, an output plate 224, a plurality of distributing shafts 225 and a distributing driving member 226. The support plate 222, the material distribution plate 223 and the output plate 224 are sequentially arranged in parallel and at intervals. The material distributing plate 223 is provided with a plurality of material distributing grooves 221 arranged at intervals. The support plate 222 is provided with mounting through holes 2221 corresponding to each distribution shaft 225. Each dispensing shaft 225 is rotatably mounted in a corresponding mounting through hole 2221. Each distributing chute 221 is located between two corresponding adjacent distributing shafts 225. The distributing driving member 226 is in driving connection with each distributing shaft 225 to drive the distributing shafts 225 to rotate.

Thus, any two adjacent distributing shafts 225 are located at the edge of the opening of the corresponding distributing groove 221. When the inner firework cylinder in the hopper 210 needs to be divided into the corresponding material dividing grooves 221, the material dividing driving part 226 needs to be utilized to drive the material dividing shaft 225 to rotate so as to drive the inner firework cylinder in the hopper 210 into the material dividing grooves 221, so that the situation that the inner firework cylinder in the hopper 210 is blocked when being divided into the material dividing structure 220 is avoided, and the material division of the inner firework cylinder in the hopper 210 is smoother.

Referring to fig. 1 and 2 again, the turnover filling mechanism 300 includes a staggered feeding structure 310 and a pushing structure 320 for fixing or releasing the firework inner barrel. The pushing structure 320 is used for pushing the firework inner barrel in the distributing groove 221 out to the staggered blanking structure 310. The staggered blanking structure 310 is used for transferring and filling the firework inner barrel in the distributing groove 221 into the firework outer barrel on the working surface 110.

Referring to fig. 4, in some embodiments, the offset blanking structure 310 includes a receiving frame 311, a blocking plate 312 fixed on the receiving frame 311, a receiving plate 313 disposed between the receiving frame 311 and the blocking plate 312, and an offset driving member 314 fixed on the receiving frame 311. The baffle 312 has a first through hole 3121. The accommodating plate 313 is provided with a second through hole 3131 at a position opposite to the first through hole 3121. The misalignment driving member 314 is used for driving the accommodating plate 313 to move so as to misalign or align the first through hole 3121 and the corresponding second through hole 3131.

In actual use, the accommodating plate 313 is driven to move by the misalignment driving member 314, so that the first through holes 3121 are aligned with the corresponding second through holes 3131; then, the pushing structure 320 pushes the firework inner barrel in the distributing groove 221 into the first through hole 3121 and the second through hole 3131; then, the containing plate 313 is driven by the misalignment driving member 314 to move reversely, so that the first through hole 3121 and the second through hole 3131 are misaligned, and the firework inner barrel is clamped. Therefore, the containing plate 313 is driven to move by the dislocation driving piece 314, so that the inner firework cylinder can conveniently enter and exit the dislocation blanking structure 310, and the inner firework cylinder can be fixed in the dislocation blanking structure 310.

Specifically, the first through holes 3121 and the second through holes 3131 are multiple, and the first through holes 3121 and the second through holes 3131 correspond to each other one by one. The plurality of first through holes 3121 are arranged in a matrix on the barrier 312, and the plurality of second through holes 3131 are also arranged in a matrix on the receiving plate 313.

Of course, in other embodiments, the plurality of first through holes 3121 and the plurality of second through holes 3131 may also be arranged in a triangular shape, a circular shape, a pentagonal shape, etc., as long as the arrangement of the plurality of first through holes 3121 and the plurality of second through holes 3131 is consistent with the circular holes on the outer firework cylinder for filling the inner firework cylinder.

The number of the first through holes 3121 and the second through holes 3131 is set to be consistent with the number of the round holes of the outer firework cylinder for filling the inner firework cylinder, when the inner firework cylinder is filled in a certain outer firework cylinder, the staggered blanking structure 310 can be used for realizing one-time filling, and the working efficiency of the filling device 10 is greatly improved.

Referring to fig. 5, in some embodiments, the pushing structure 320 includes a mounting bracket 321 mounted on the machine body 100, a pushing driving member 322, a pushing frame 323 mounted on the mounting bracket 321, and a pushing rod 324 mounted on a side of the pushing frame 323 facing the material distributing groove 221. The pushing driving member 322 is used to drive the pushing frame 323 to drive the pushing rod 432 to move in a direction away from the material distributing groove 221. Specifically, when the pushing driving member 322 drives the push rod 432 to move in the direction toward the distributing groove 221, the inner firework cylinder in the distributing groove 221 can be pushed into the staggered blanking structure 310; when the pushing drive 322 drives the push rod 432 to move in a direction away from the chute 221, the push rod 432 can be reset. When there are a plurality of distributing grooves 221, there are a plurality of pushing rods 324. Each of the pushing rods 324 is used for pushing out the inner firework cylinder in the corresponding distributing chute 221.

Referring to fig. 6, in detail, when the material distributing structure 220 includes a supporting plate 222, a material distributing plate 223 and an output plate 224, the supporting plate 222 further has material pushing through holes 2222 corresponding to and communicating with each material distributing groove 221, and the output plate 224 has strip-shaped through holes 2241 corresponding to and communicating with each material distributing groove 221 along the depth direction of the material distributing groove 221. When the device is used, the pushing driving member 322 drives the pushing rod 324 to move along the direction towards the material distributing groove 221, and the pushing rod sequentially passes through the pushing through hole 2222 and the material distributing groove 221, so that the firework inner cylinder in the material distributing groove 221 is pushed into the staggered blanking structure 310 through the strip-shaped through hole 2241.

Referring to fig. 2 again, the detecting mechanism 400 includes a cold light source 410, a photoelectric sensor 420 and a discharging structure 430. The cold light source 410 is used for emitting a cold light beam which can pass through the firework inner barrel in the material passing groove 221. Specifically, the cold light source 410 may be a point light source or a strip light source, and the cold light beam emitted by the cold light source 410 may be a fluorescent beam or a phosphor beam. The photoelectric sensor 420 is used for sensing a cold light beam emitted by the cold light source 410 and triggering the discharging structure 430 to act so as to push the empty firework inner barrel out of the distributing groove 221. When the distributing structure 220 includes the supporting plate 222, the distributing plate 223 and the supporting plate 222, the photoelectric sensor 420 is located on a side of the output plate 224 away from the distributing plate 223, and the cold light source 410 and the discharging structure 430 are both located on a side of the supporting plate 222 away from the distributing plate 223.

Specifically, when the cold light beam emitted by the cold light source 410 passes through the firework inner cylinder located in the distributing groove 221 and reaches the surface of the photoelectric sensor 420, it is indicated that the firework inner cylinder is an empty firework inner cylinder without powder packaging, and at this time, the photoelectric sensor 420 triggers the discharging structure 430 to act, so as to push the empty firework inner cylinder out of the distributing groove 221; when the cold light beam emitted by the cold light source 410 cannot pass through the firework inner barrel in the distributing groove 221 to reach the surface of the photoelectric sensor 420, it indicates that the firework inner barrel is a firework inner barrel packaged with gunpowder, and at this time, the filling device 10 can be used to continue the subsequent action on the firework inner barrel.

It should be noted that the detection elements such as the cold light source 410 and the photoelectric sensor 420 are all elements that meet the safety standards of the firework and firecracker production and operation enterprises.

Referring also to fig. 7, in some embodiments, the discharging structure 430 includes a discharging bracket 431 mounted on the material distributing structure 220, a push rod 432 mounted on the discharging bracket 431, and a discharging driving member 433. Specifically, when the material distributing structure 220 includes the supporting plate 222, the material distributing plate 223 and the output plate 224, the material discharging bracket 431 is mounted on the supporting plate 222. The push rod 432 is aligned with the chute 221. The discharging driving member 433 is used for driving the push rod 432 to stretch under the triggering of the photoelectric sensor 420 so as to push the empty firework inner barrel out of the distributing groove 221. The end of the push rod 432 facing the distributing groove 221 has a mounting groove 4321. The cold light source 410 is installed in the installation groove 4321.

Specifically, when there are a plurality of distributing troughs 221, the photoelectric sensors 420, the push rods 432, and the discharging driving members 433 are all plural, and each distributing trough 221 corresponds to one push rod 432, one discharging driving member 433, and one photoelectric sensor 420. If the cold light sources 410 are point light sources, the number of the cold light sources 410 is multiple, and the cold light sources are respectively in one-to-one correspondence with the plurality of distributing grooves 221; if the cold light source 410 is a strip light source, the number of the cold light sources 410 may be one, and the longitudinal direction of the cold light source 410 is perpendicular to the spacing direction of the plurality of sub-troughs 221. When the cold light beam emitted by the cold light source 410 passes through the firework inner cylinder in one of the distributing grooves 221 to reach the corresponding photoelectric sensor 420, the photoelectric sensor 420 triggers the corresponding discharging driving member 433 to drive the discharging push rod 432 to extend and retract, so as to push the empty firework inner cylinder out of the distributing groove 221.

Referring to fig. 3 again, specifically, when the material distributing structure 220 includes a supporting plate 222, a material distributing plate 223 and an output plate 224, the supporting plate 222 further defines a material discharging through hole 2223 corresponding to and communicating with each material distributing groove 221. During the use, when ejection of compact driving piece 433 drive push rod 432 extended, passed ejection of compact through-hole 2223 and divide the silo 221 in proper order to divide silo 221 with the propelling movement of empty fireworks inner tube through rectangular shape through-hole 2241.

The working process of filling the firework inner barrel to the firework outer barrel by using the filling device 10 is as follows:

(1) firstly, a plurality of firework inner cylinders are placed in the hopper 210 manually or mechanically;

(2) the inner firework cylinder of the hopper 210 moves downwards into the distributing groove 221 under the action of the gravity of the inner firework cylinder, and the distributing driving part 226 is driven in the process to drive the distributing shaft 225 to rotate so as to ensure that the inner firework cylinder in the hopper 210 can be smoothly distributed into the distributing groove 221;

(3) starting the detection mechanism 400, and irradiating the firework inner barrel in the distributing groove 221 by using a cold light beam emitted by the cold light source 410; if the inner firework cylinder is detected to be an empty inner firework cylinder, the discharging structure 430 is triggered to push the empty inner firework cylinder out of the distributing groove 221; if the inner firework cylinder is detected to be the inner firework cylinder packaged with gunpowder, the inner firework cylinder continues to move downwards to a position aligned with the material pushing structure 320;

(4) the pushing structure 320 acts to push the detected firework inner barrel in the distributing groove 221 into the staggered blanking structure 310;

(5) the offset blanking structure 310 acts to fill the firework inner barrel into the firework outer barrel located at the working face 110.

Therefore, the detection mechanism 400 is firstly utilized to detect the firework inner barrel so as to remove the empty firework inner barrel without gunpowder, and then the overturning filling mechanism 300 is utilized to fill the detected firework inner barrel into the firework outer barrel of the working face 110 so as to prevent the empty firework inner barrel without gunpowder from being filled into the firework outer barrel, thereby greatly improving the quality of the fireworks.

Referring to fig. 8, in some embodiments, the detecting mechanism 400 further includes a mounting plate 440, the mounting plate 440 is mounted on a side of the distributing structure 220 facing away from the cold light source 410 and is rotatable in a direction facing away from or toward the distributing structure 220. Referring again to fig. 2, the photoelectric sensor 420 is mounted on the surface of the mounting plate 440 facing the distributing trough 221 and aligned with the distributing trough 221.

When the material distributing structure 220 includes the supporting plate 222, the material distributing plate 223 and the output plate 224, the mounting plate 440 is mounted on the output plate 224, and the photoelectric sensor 420 is aligned with the elongated through hole 2241. When the number of the distributing grooves 221 is plural, the mounting plate 440 extends along the direction of the interval of the distributing grooves 221, and the plurality of the photoelectric sensors 420 are disposed at intervals along the direction of the extension of the mounting plate 440.

In the actual use process, when the inner firework cylinder in the distributing groove 221 needs to be detected, the mounting plate 440 is parallel to the output plate 224, and at the moment, the photoelectric sensor 420 is aligned with the distributing groove 221 so as to conveniently detect the inner firework cylinder in the distributing groove 221; when detecting that the fireworks inner tube in the distributing groove 221 is an empty fireworks inner tube and pushing the empty fireworks inner tube out of the distributing groove 221 by the push rod 432, the empty fireworks inner tube drives the mounting plate 440 to rotate towards the direction deviating from the distributing groove 221 under the action of the thrust provided by the push rod 432, so that the hole fireworks inner tube can come out from the distributing groove 221. Therefore, the installation plate 440 not only facilitates the installation of the photoelectric through sensor, but also facilitates the detection and the release of the inner firework cylinder in the distributing chute 221.

Referring again to fig. 2 and 8, in some embodiments, the detection mechanism 400 further includes a receiving bin 450. The receiving bin 450 is installed at one side of the material separating structure 220 where the photoelectric sensor 420 is arranged. The discharging structure 430 is used for pushing the empty firework inner barrel in the distributing groove 221 out to the material receiving bin 450. The receiving bin 450 is used for collecting the empty firework inner cylinders pushed out from the distributing bin 221 so as to prevent the empty firework inner cylinders from scattering to the ground around the filling device 10, so that the environment around the filling device 10 is messy and the working environment is affected; the material receiving bin 450 can also prevent the empty firework inner barrel from dropping to the working surface 110, the feeding device, the discharging device and the like, so as to ensure the smooth operation of the firework inner barrel machine.

Specifically, the receiving bin 450 is mounted to the outer side of the output plate 224 and is located on the side of the mounting plate 440 facing the work surface 110. When the filling device 10 is positioned in a horizontal plane, the receiving bin 450 is positioned below the mounting plate 440. When the distributing grooves 221 are multiple, the receiving bin 450 is of a long strip-shaped structure, and the longitudinal direction of the receiving bin 450 is consistent with the interval direction of the distributing grooves 221.

Referring also to fig. 9, in some embodiments, the flipping filler mechanism 300 further comprises a vertical lift structure 330. The vertical pulling structure 330 is connected to the offset blanking structure 310 and is used to drive the offset blanking structure 310 to reciprocate along the first direction 20 perpendicular to the working surface 110. The first direction 20 is a vertical direction when the filling device 10 is located in a horizontal plane. When a plurality of distributing grooves 221 are formed, each time the pushing structure 320 acts, a plurality of firework inner cylinders can be pushed to the staggered blanking structure 310 at one time, and a row is formed on the staggered blanking structure 310; when the vertical lifting structure 330 drives the dislocation blanking structure 310 to lift along the vertical direction, a plurality of rows of firework inner cylinders can be fixed on the dislocation blanking structure 310.

Specifically, when the offset blanking structure 310 includes the receiving bracket 311, the receiving plate 313, the blocking plate 312, and the offset driving member 314, the offset driving member 314 is configured to drive the receiving plate 313 to move along the second direction 30 perpendicular to the first direction 20, so as to offset or align the first through hole 3121 and the corresponding second through hole 3131. The first direction 20 is a horizontal direction parallel to a vertical plane when the packing arrangement 10 is located on a horizontal plane. That is, the accommodating plate 313 moves in a horizontal direction to achieve the placement and fixation of the firework inner barrel in the first through hole 3121 and the second through hole 3131.

Specifically, the vertical pulling structure 330 includes a fixing plate 331 fixed to the body 100, a plurality of brackets 332, a vertical pulling driving member 333, and a weight member 334. The fixing plate 331 is mounted on the body 100. Both ends of each bracket 332 are respectively connected with the fixing plate 331 and the flip structure 340. The vertical pulling driving member 333 is installed on the fixing plate 331 and drives the offset discharging structure 310 to move up and down along the first direction 20. The weight member 334 is installed on a side of the fixing plate 331 facing away from the offset blanking structure 310. The counterweight 334 can be selected from a cylinder/oil cylinder with a proper type or a counterweight, so that the equipment runs more stably, and the abrasion of the equipment is reduced.

Referring again to fig. 4, in some embodiments, the flipping mechanism 300 further comprises a flipping mechanism 340. The turning structure 340 is in transmission connection with the misplaced blanking structure 310 to drive the misplaced blanking structure 310 to switch between a material taking state close to the material distributing structure 220 and a material filling state rotating by a preset angle.

When the staggered blanking structure 310 is in a material taking state, the material pushing structure 320 is used for pushing the firework inner barrel in the material distributing groove 221 into the staggered blanking structure 310. When the staggered blanking structure 310 is in a filling state, the firework inner barrel in the staggered blanking structure 310 is filled into the firework outer barrel of the working surface 110 under the action of gravity of the firework inner barrel.

Specifically, when the filling device 10 is located on the horizontal plane and the staggered blanking structure 310 is located in the material taking state, the staggered blanking structure 310 is perpendicular to the working plane 110; when the staggered blanking structure 310 is in a filling state, the staggered blanking structure 310 is parallel to the working surface 110, so the preset angle is 90 degrees. Therefore, the overturning structure 340 is mainly used for driving the dislocation blanking structure 310 to overturn, so that the dislocation blanking structure 310 is switched between a material taking state and a filling state, and the inner firework cylinder is transferred from the material distributing groove 221 to the working surface 110 into the outer firework cylinder. Of course, according to actual requirements, the preset angle of the rotation of the staggered blanking structure 310 may be smaller than 90 degrees or larger than 90 degrees.

Further, in some embodiments, the flipping mechanism 340 includes a first link 341, a second link 342, a flipping plate 343 rotatably mounted on the second link 342, and a telescopic member 344. The first and

second links

341 and 342 are parallel and spaced apart. The receiving bracket 311 is fixed to the first link 341. One end of the turning plate 343 is movably connected with the first link 341. Two ends of the telescopic member 344 are movably connected with one end of the flip plate 343 away from the first connecting rod 341 and the accommodating bracket 311, respectively. The telescoping member 344 is telescopable in its lengthwise direction.

Wherein, the telescopic part 344 can be a telescopic rod, an electric cylinder, etc. A link mechanism is formed among the first connecting rod 341, the second connecting rod 342, the turnover plate 343, the telescopic member 344 and the accommodating bracket 311, and when the telescopic member 344 is extended, the staggered blanking structure 310 is in a material taking state; when the telescopic rod is retracted, the offset blanking structure 310 is in the filling device 10. Thus, the shifting mechanism 310 can be switched between the material-taking state and the material-filling state by the expansion of the expansion piece 344.

When the firework inner barrel machine and the filling device 10 thereof are used, the firework inner barrel in the hopper 210 is divided into the material distributing grooves 221 under the action of the gravity of the firework inner barrel; then, the cold light beam emitted by the cold light source 410 irradiates on the firework inner cylinder of the distributing groove 221; if the photoelectric sensor 420 senses a cold light beam, it indicates that the firework inner cylinder is empty, at this time, the optical sensor triggers the discharging structure 430 to act, so as to push the empty firework inner cylinder out of the distributing groove 221; if the photoelectric sensor 420 does not sense the cold light beam, it indicates that gunpowder is in the firework inner barrel, and at this time, the firework inner barrel moves downward to a position opposite to the material pushing structure 320 under the action of its own gravity, and the material pushing structure 320 is utilized to push the firework inner barrel from the material distributing groove 221 into the staggered blanking structure 310; then the staggered blanking structure 310 fills the firework inner barrel into the firework outer barrel of the working surface 110. Therefore, by using the detection mechanism 400, before the firework inner barrel is pushed into the staggered blanking structure 310, the firework inner barrel in the branch material slot 221 can be detected, and the empty firework inner barrel which is not packed with gunpowder is pushed out of the branch material slot 221, so that the firework inner barrel packed into the firework outer barrel is packed with gunpowder, and therefore, the quality of the fireworks is greatly improved by using the packing device 10.
