Description

Technical Field

[0001] This application relates to the field of fireworks production equipment technology, and in particular to an inner cylinder filling device and a combined fireworks production line. Background Technology

[0002] The outer tube of a combination firework contains an inner tube, also known as a firework effects tube. This inner tube contains glitter beads, gunpowder, fillers, and igniters; both the glitter beads and gunpowder are flammable and explosive. When ignited, it produces various effects, such as vibrant colors and various sounds. Currently, in the fireworks production process, an inner tube filling device is used to fill the outer tube. This device has a hopper for loading the inner tubes. The inner tubes in the hopper first fall onto a slide, and then are pushed out sequentially by a pushing mechanism. After the pushing mechanism pushes the inner tubes off the slide, they need to be further transferred to the combination firework. The efficiency of this process still has room for improvement.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0039] This application provides an inner tube filling device and a combined fireworks production line including the inner tube filling device. In some technical solutions, the inner tube filling device can be used to directly fill the inner tube of fireworks; in other technical solutions, the inner tube filling device fills the inner tube onto a transfer template, the transfer template being provided with multiple rows of receiving holes, which can receive the inner tubes falling from the inner tube filling device row by row and transfer them to the combined fireworks to be filled.

[0040] refer to Figures 1-3 The inner cylinder filling device includes: a base 40, a discharge assembly 10, a rotating mechanism 20, and a pushing mechanism 30. The discharge assembly 10 includes: a hopper 11, multiple discharge chutes 12, and a pushing mechanism 13; the multiple discharge chutes 12 extend in the same direction and are located below the hopper 11 to receive the inner cylinder falling from the hopper 11; the pushing mechanism 13 is used to push the inner cylinders on the multiple discharge chutes 12 forward.

[0041] Specifically, when the inner cylinder filling device is in operation, the operator loads the inner cylinder into the hopper 11. The inner cylinder in the hopper 11 falls onto the discharge chute 12 below and is pushed out by the pushing mechanism 13. The pushing mechanism 13 includes a pushing component 131 and a sixth driving element 132. The pushing component 131 is provided with multiple pushing parts corresponding to the multiple discharge chute 12. As the sixth driving element 132 drives the pushing component 131 to move back and forth, the multiple pushing parts push the inner cylinders on the multiple discharge chute 12 forward.

[0042] The rotating mechanism 20 includes a drive source and a rotating structure 22. The rotating structure 22 is located in front of multiple discharge chutes 12. The rotating structure 22 includes a rotating shaft 221, and a first filling component 222a, a second filling component 222b, a third filling component 222c, and a fourth filling component 222d are evenly distributed around the rotating shaft 221 in a circumferential direction. Along the axial direction of the rotating shaft 221, each filling component has multiple radial filling holes 2221 arranged at corresponding positions. The first filling component 222a... The first filling component 222a and the second filling component 222b are located opposite each other, and their filling holes 2221 are aligned and interconnected through a through hole on the rotating shaft 221, forming a pair of filling components; the second filling component 222b and the fourth filling component 222d are located opposite each other, and their filling holes 2221 are aligned and interconnected through a through hole on the rotating shaft 221, forming a pair of filling components; the rotating shaft 221 is rotatably mounted on the machine base, and the drive source is poweredly connected to the rotating shaft 221 to drive the rotating structure 22 to rotate. The drive source drives the rotating structure 22 to rotate, causing the filling holes 2221 on the first filling component 222a, the second filling component 222b, the third filling component 222c, and the fourth filling component 222d to sequentially approach and align with multiple discharge chutes 12 to receive the inner cylinder pushed out from the multiple discharge chutes 12.

[0043] The push mechanism 30 is located above the rotating structure 22 and is used to push down the inner cylinder in the filling hole 2221 of the filling unit for material filling; when the filling hole 2221 of any filling unit is aligned with the multiple discharge slides 12, the filling holes 2221 of the adjacent pair of filling units are aligned with the push mechanism 30.

[0044] Specifically, the rotating structure 22 is positioned in front of the plurality of discharge chutes 12, and can receive the inner cylinder pushed forward from the plurality of discharge chutes 12. The rotating structure 22 includes a rotating shaft 221, and a first filling section 222a, a second filling section 222b, a third filling section 222c, and a fourth filling section 222d are evenly spaced around the rotating shaft 221 in a sequential manner. (Reference) Figure 2 The first filling component 222a, the second filling component 222b, the third filling component 222c, and the fourth filling component 222d form a cross-shaped structure. The first filling component 222a and the third filling component 222c are located in opposite positions, forming a pair of filling components; the second filling component 222b and the fourth filling component 222d are located in opposite positions, forming a pair of filling components.

[0045] refer to Figure 5In one specific embodiment, the rotating shaft 221 is configured as a square structure along the length corresponding to the filling parts. The square structure has four sides, and the first filling part 222a, the second filling part 222b, the third filling part 222c, and the fourth filling part 222d are respectively arranged on the four sides. Through holes 2211 are provided between opposite sides to connect the filling holes 2221 of the two filling parts.

[0046] Furthermore, the drive source can drive the rotating structure 22 to rotate so that the filling holes on the first filling section 222a, the second filling section 222b, the third filling section 222c, and the fourth filling section 222d sequentially approach and align with the multiple discharge slides to receive the inner cylinder pushed out by the multiple discharge slides 12. Moreover, when any filling section is aligned with the discharge slide 12, the filling holes of its adjacent pair of filling sections are aligned with the downward pushing mechanism, thereby enabling the simultaneous receiving and filling of the inner cylinder. As the rotating structure 22 rotates, the rotating mechanism 22 can continuously receive the inner cylinder pushed out by the discharge slide 12 and fill it downward, resulting in high working efficiency.

[0047] Furthermore, the pushing mechanism 30 includes a pushing member 31 and a fifth driving element 32; the fifth driving element 32 is used to drive the pushing member 31 to move up and down to insert into the filling hole 2221 of the lower filling part and push the inner cylinder downward. When the filling hole of the filling part is aligned with the pushing mechanism, the pushing member 31 can be inserted downward into the filling hole 2221 to force the inner cylinder downward.

[0048] exist Figure 2 In the structure shown, the first filling component 222a and the third filling component 222c are located in opposite positions, forming a pair of filling components. The first filling component 222a is close to and aligned with multiple discharge chutes 12. The pushing mechanism 13 can push the inner cylinder on the discharge chutes 12 to the filling hole 2221 of the first filling component 222a. At the same time, the second filling component 222b and the fourth filling component 222d are located in opposite positions, forming a pair of filling components, and both are aligned with the pushing mechanism 30. The pushing mechanism 30 can push down the inner cylinder in the filling hole 2221 of the filling component for material filling. As the rotating structure 22 rotates, the second filling component 222b, the third filling component 222c, and the fourth filling component 222d successively replace the position of the first filling component 222a.

[0049] exist Figure 2 and Figure 3In the structure shown, the inner cylinder filling device fills the inner cylinder onto the transfer template 50. The transfer template 50 is provided with multiple rows of receiving holes, which can receive the inner cylinders falling from the inner cylinder filling device row by row and transfer them to the combination fireworks to be filled. During filling, the filling hole 2221 of the filling unit is aligned with the pushing mechanism 30. The pushing member 31 can be inserted downward into the filling hole 2221 to force the inner cylinder downward. The inner cylinder in the filling hole 2221 falls into the receiving hole on the lower transfer template 50.

[0050] refer to Figures 4-6 In the first embodiment of this application, each filling segment is further provided with a first baffle mechanism, and the first baffle mechanism corresponds one-to-one with the filling segment, capable of opening or closing the filling hole 2221 of the corresponding filling segment; for any filling segment and its corresponding first baffle mechanism, the first baffle mechanism is arranged on the side of the filling segment near the rotating shaft 221. Further, when any filling segment is aligned with multiple discharge slides, its corresponding first baffle mechanism closes the filling hole 2221, and when the filling segment rotates upward to align with the push mechanism, its corresponding first baffle mechanism opens the filling hole 2221, thereby allowing the inner cylinder inside the filling hole 2221 of the filling segment to pass downward through the first baffle mechanism and the opposite filling segment for material filling.

[0051] exist Figure 2 In the structure shown, the filling hole 2221 of the first filling section 222a approaches and aligns with the multiple discharge slides 12. The corresponding first baffle mechanism closes the filling hole 2221 of the first filling section 222a. At this time, the pushing mechanism 13 pushes the inner cylinder on the multiple discharge slides 12 forward and into the filling hole 2221 of the first filling section 222a. The first baffle mechanism can block the inner cylinder and prevent the pushing mechanism 13 from pushing the inner cylinder out of the filling hole 2221 of the first filling section 222a from the other end. Furthermore, the first filling section 222a rotates upward. When the first filling section 222a rotates to the state aligned with the pushing mechanism, the first material blocking mechanism opens the filling hole 2221 of the first filling section 222a, thereby allowing the inner cylinder inside the filling hole 2221 of the first filling section 222a to pass downward through the first material blocking mechanism and the filling section at the opposite position for material feeding.

[0052] Furthermore, the first baffle mechanism 23 includes a first baffle 231 and a first drive element; the first baffle 231 corresponds one-to-one with the filling section; for the filling section and the corresponding first baffle 231, the first baffle 231 is arranged on the side of the filling section near the rotating shaft 221; the first baffle 231 is provided with a first material passage hole 2311, and the first material passage hole 2311 corresponds one-to-one with the filling hole 2221 on the filling section; the first drive element can drive the first baffle 231 to move so that the first material passage hole 2311 is aligned or offset from the filling hole 2221. When the first baffle 231 is activated to align the first material passage hole 2311 with the filling hole 2221, the filling hole 2221 is in the open state, allowing the inner cylinder to pass through; conversely, when the first baffle 231 is activated to misalign the first material passage hole 2311 with the filling hole 2221, the filling hole 2221 is in the closed state, blocking the inner cylinder from passing through.

[0053] Specifically, when any filling component is aligned with the plurality of discharge slides 12, the first material passage hole 2311 of the corresponding first material stop 231 is offset from the filling hole 2221 to block the inner cylinder. When the filling component rotates upward to align with the push mechanism, the corresponding first material stop 231 moves to align the first material passage hole 2311 with the filling hole, thereby allowing the inner cylinder in the filling hole of the filling component to pass downward through the first material passage hole 2311 of the first material stop 231 and the filling component at the opposite position for material feeding.

[0054] In the second embodiment of this application, each filling section is further provided with a second baffle mechanism, and the second baffle mechanism corresponds one-to-one with the filling section, capable of opening or closing the filling hole 2221 of the corresponding filling section; for any filling section and its corresponding second baffle mechanism, the second baffle mechanism is arranged on the side of the filling section away from the rotating shaft 221. Further, when any filling section is aligned with multiple discharge slides, its corresponding second baffle mechanism opens the filling hole 2221, and after the inner cylinder enters the filling hole 2221, its corresponding second baffle mechanism closes the filling hole 2221; when the filling section rotates downward to the state aligned with the push mechanism, its corresponding second baffle mechanism opens the filling hole 2221, so that the inner cylinder in the filling hole 2221 of the filling section can be filled downward.

[0055] Specifically, the second baffle mechanism is arranged on the side of the filling section away from the rotating shaft 221. When the filling section is aligned with the discharge chute, the second baffle mechanism opens the filling hole 2221, and the pushing mechanism 13 pushes the inner cylinders on the multiple discharge chute 12 forward into the corresponding filling holes 2221. After feeding, the second baffle mechanism closes to prevent the filling section from sliding down during downward rotation. When the filling section rotates downward to the alignment state with the pushing mechanism, its corresponding second baffle mechanism opens the filling hole 2221, allowing the inner cylinder in the filling hole 2221 of the filling section to be filled downward.

[0056] refer to Figure 7 The second material blocking mechanism 24 includes a second material blocking component 241 and a second driving element. The second material blocking component 241 corresponds one-to-one with the filling section. For the filling section and the corresponding second material blocking component 241, the second material blocking component 241 is arranged on the side of the filling section away from the rotating shaft 221. The second material blocking component 241 is provided with a second material passage hole 2411, and the second material passage hole 2411 corresponds one-to-one with the filling hole 2221 on the filling section. The second driving element can drive the second material blocking component 241 to move so that the second material passage hole 2411 is aligned or offset from the filling hole 2221. When the second baffle 241 is activated to align the second material passage 2411 with the filling hole 2221, the filling hole 2221 is in the open state, allowing the inner cylinder to pass through; conversely, when the second baffle 241 is activated to misalign the second material passage 2411 with the filling hole 2221, the filling hole 2221 is in the closed state, blocking the inner cylinder from passing through.

[0057] In the third embodiment of this application, each filling segment is further provided with a third blocking mechanism and a fourth blocking mechanism; the third blocking mechanism corresponds one-to-one with the filling segment and can be operated to open or close the filling hole 2221 of the corresponding filling segment; the fourth blocking mechanism corresponds one-to-one with the filling segment and can be operated to open or close the filling hole 2221 of the corresponding filling segment; for any filling segment and its corresponding third blocking mechanism and fourth blocking mechanism; the third blocking mechanism is arranged on the side of the filling segment close to the rotating shaft 221, and the fourth blocking mechanism is arranged on the side of the filling segment away from the rotating shaft 221. When any filling section is aligned with multiple discharge slides, its corresponding third baffle mechanism closes the filling hole 2221, and its corresponding fourth baffle mechanism opens the filling hole 2221. After the inner cylinder enters the filling hole 2221, its corresponding fourth baffle mechanism closes the filling hole 2221, and its corresponding third baffle mechanism opens the filling hole 2221. When the filling section rotates downward to align with the push mechanism, its corresponding fourth baffle mechanism opens the filling hole 2221.

[0058] Specifically, the third baffle mechanism is arranged on the side of the filling section near the rotating shaft 221, and the fourth baffle mechanism is arranged on the side of the filling section away from the rotating shaft 221. When any filling section is aligned with multiple discharge slides, its corresponding third baffle mechanism closes the filling hole 2221, and its corresponding fourth baffle mechanism opens the filling hole 2221. At this time, the pushing mechanism 13 pushes the inner cylinder on the multiple discharge slides 12 forward and into the corresponding filling hole 2221. The third baffle mechanism can block the inner cylinder, preventing the pushing mechanism 13 from pushing the inner cylinder out of the corresponding filling hole 2221 from the other end. After feeding, the fourth baffle mechanism closes the filling hole 2221 to prevent the filling section from sliding down during downward rotation; and the third baffle mechanism opens the filling hole 2221. When the filling unit rotates downwards to align with the push mechanism, its corresponding fourth baffle mechanism opens the filling hole 2221. At this time, both the third and fourth baffle mechanisms are in the open state, and the push mechanism 30 can push the inner cylinder inside the filling hole 2221 of the filling unit to perform material feeding.

[0059] Furthermore, the third stop mechanism 25 includes a third stop component 251 and a third drive element; the third stop component 251 corresponds one-to-one with the filling unit; see reference. Figure 8 For the filling section and its corresponding third stop 251, the third stop 251 is arranged on the side of the filling section near the rotating shaft 221. A third material passage hole is arranged on the third stop 251, and the third material passage hole corresponds one-to-one with the filling hole 2221 on the filling section. A third driving element can drive the third stop 251 to align or offset the third material passage hole with the filling hole 2221. When the third stop 251 aligns the third material passage hole with the filling hole 2221, the filling hole 2221 is open, allowing the inner cylinder to pass through; conversely, when the third stop 251 offsets the third material passage hole with the filling hole 2221, the filling hole 2221 is closed, blocking the inner cylinder from passing through.

[0060] Furthermore, the fourth baffle mechanism 26 includes a fourth baffle 261 and a fourth drive element; the fourth baffle 261 corresponds one-to-one with the filling section; for the filling section and the corresponding fourth baffle 261, the fourth baffle 261 is arranged on the side of the filling section away from the rotating shaft 221; a fourth material passage hole is arranged on the fourth baffle 261, and the fourth material passage hole corresponds one-to-one with the filling hole 2221 on the filling section; the fourth drive element can drive the fourth baffle 261 to move so that the fourth material passage hole and the filling hole 2221 are aligned or misaligned. When the fourth baffle 261 moves to align the fourth material passage hole with the filling hole 2221, the filling hole 2221 is in the open state, allowing the inner cylinder to pass through; conversely, when the fourth baffle 261 moves to misalign the fourth material passage hole with the filling hole 2221, the filling hole 2221 is in the closed state, blocking the inner cylinder from passing through.

[0061] It should be understood that the rotation direction of the rotating structure 22 needs to be set according to the specific structure. In the first embodiment of this application, after receiving the inner cylinder pushed out by the discharge slide 12, the filling part rotates upward to align with the pushing mechanism. In the second and third embodiments of this application, after receiving the inner cylinder pushed out by the discharge slide 12, the filling part rotates downward to align with the pushing mechanism.

[0062] This application also provides a combined fireworks production line, including the inner cylinder filling device described in the previous section, which is used in the inner cylinder filling process. The combined fireworks production line may also include other production equipment, such as paper filling and military-grade nitrous oxide filling. The improvements in this application relate to inner cylinder filling equipment; relevant details are provided in the previous section and will not be repeated here.

[0063] In the inner cylinder filling device provided in this application, a rotating mechanism is used to transfer and fill the inner cylinder pushed out by the pushing mechanism. The rotating structure includes a rotating shaft, and a first filling component, a second filling component, a third filling component, and a fourth filling component are evenly spaced around the rotating shaft in sequence. A drive source drives the rotating structure to rotate, so that the filling holes on the first filling component, the second filling component, the third filling component, and the fourth filling component sequentially approach and align with multiple discharge slides to receive the inner cylinder pushed out from the multiple discharge slides. Furthermore, when any filling component is aligned with a discharge slide, the filling holes of its adjacent pair of filling components are aligned with the pushing mechanism, thereby enabling simultaneous receiving and filling of the inner cylinder. As the rotating structure rotates, the rotating mechanism can continuously receive the inner cylinder pushed out by the discharge slides and fill it downwards, resulting in high working efficiency.
