Detailed implementation manners

[0029] The following are specific embodiments of the present application and in combination with the accompanying drawings, the technical solutions of the present application are further described, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of the embodiments of the present application. Therefore, those skilled in the art should clearly understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of known functions and structures are omitted for clarity and conciseness.

[0030] It should be noted that, without conflict, the implementation manners and features in the implementation manners of the present application can be combined with each other.

[0031] The embodiment of the present application provides a discharging device for the inner tube of fireworks. The discharging device for the inner tube of fireworks is used to discharge and push out the inner tube of fireworks in the hopper for the next step of loading.

[0032] Refer to Figure 1 and Figure 2, the inner tube discharging device of the fireworks includes a hopper 10, a plurality of discharging chutes 20, a blanking assembly 30, and a pushing mechanism 40; among them, a material trough 11 for the inner tube of the fireworks is provided on the hopper 10; the plurality of discharging chutes 20 extend in the same direction and are horizontally arranged below the material trough 11; the blanking assembly 30 includes an upper blanking frame 31, a lower blanking frame 32, and a first driving source 33; both the upper blanking frame 31 and the lower blanking frame 32 are located between the material trough 11 and the plurality of discharging chutes 20, and the upper blanking frame 31 is located above the lower blanking frame 32; a plurality of upper blanking channels 311 are provided on the upper blanking frame 31, and a plurality of lower blanking channels 321 are provided on the lower blanking frame 32; the plurality of lower blanking channels 321 are aligned with the plurality of discharging chutes 20 one by one; the plurality of upper blanking channels 311 correspond to the plurality of lower blanking channels 321 one by one for guiding the inner tubes of the fireworks in the material trough 11 into the plurality of lower blanking channels 321; the first driving source 33 is used to drive the upper blanking frame 31 to vibrate; the pushing mechanism 40 is used to push the inner tubes of the fireworks on the plurality of discharging chutes 20 forward.

[0033] When the inner tube discharging device of the fireworks is working, the operator loads the inner tubes of the fireworks into the material trough 11 of the hopper 10. The inner tubes of the fireworks in the material trough 11 will first fall into the upper blanking channels 311 of the upper blanking frame 31. The inner tubes of the fireworks in the upper blanking channels 311 move downward along the upper blanking channels 311 and continue to fall into the lower blanking channels 321 of the lower blanking frame 32. The inner tubes of the fireworks in the lower blanking channels 321 continue to move downward along the lower blanking channels 321 and fall into the discharging chutes 20 below. After the inner tubes of the fireworks fall into the discharging chutes 20, they will be pushed forward by the pushing mechanism 40 for the next step of loading. After the above process, the inner tubes of the fireworks fall from the material trough 11 of the hopper 10 into the discharging chutes 20 and are pushed out by the pushing mechanism 40. During the above blanking process, the first driving source 33 drives the upper blanking frame 31 to vibrate, which can make the inner tubes of the fireworks in the material trough 11 enter the upper blanking channels 311 more smoothly, and the upper blanking channels 311 can also enter the lower blanking channels 321 more smoothly, reducing the probability of the inner tubes of the fireworks getting stuck during the blanking process and reducing the safety risk.

[0034] In Figure 1 and Figure 2 the structure shown, the plurality of upper blanking channels are separated by a plurality of first partitions distributed at intervals; the plurality of lower blanking channels are separated by a plurality of second partitions distributed at intervals.

[0035] Continue to refer to Figure 3, in an embodiment of the present application, the width of the upper feeding channel 311 is wider than that of the lower feeding channel 321. In this design, the width of the upper feeding channel 311 is relatively wide, which can make the fireworks inner tubes in the material trough 11 more easily enter the upper feeding channel 311 and more smoothly pass through the upper feeding channel 311 and enter the lower feeding channel 321 below. Further, the width of the lower feeding channel 321 gradually narrows from top to bottom. Here, the lower feeding channel 321 is designed with a wider upper part and a narrower lower part. Its upper end is designed wider to more smoothly receive the fireworks inner tubes falling out of the upper feeding channel 311, and its lower end is designed narrower, which can make the fireworks inner tubes more accurately fall into the lower discharging chute 20.

[0036] Reference Figure 3 And Figure 4 , in an embodiment of the present application, a plurality of first partitions 312 are horizontally and spaced apart on the upper feeding rack 31, and a plurality of upper feeding channels 311 are separated by the plurality of first partitions 312; the lower ends of the first partitions 312 are rotatably connected to the hopper 10, and the first driving source 33 can drive the first partitions 312 to reciprocally shake around the connection part between them and the hopper 10. Here, the first driving source 33 can be various types of driving elements, such as an electric device, a pneumatic device, etc. Driven by the first driving source, the first partitions 312 can reciprocally rotate (shake) relative to the hopper 10 within a certain angle range. Through shaking, it can promote the fireworks inner tubes to enter the lower feeding channel through the upper feeding channel, and the feeding process is smoother.

[0037] Reference Figure 3 And Figure 4 , in an embodiment of the present application, a horizontal connecting member 313 is further provided on the upper feeding rack 31, and the first partition 312 is rotatably connected to the horizontal connecting member 313; the first driving source 33 has a driving shaft capable of outputting rotation; a rotating member 34 is installed on the driving shaft; a connecting rod 35 is provided between the rotating member 34 and the upper feeding rack 31; the first end of the connecting rod 35 is rotatably connected to the rotating member 34, and the connection position deviates from the rotation axis; the second end of the connecting rod 35 is rotatably connected to the horizontal connecting member 313 of the upper feeding rack 31. Specifically, the first driving source 33 can be set as a motor, and its driving shaft can output rotation. When the driving shaft rotates, the rotating member 34 installed thereon also rotates. Since the connecting rod 35 is connected between the rotating member 34 and the upper feeding rack 31, the upper feeding rack 31 will also move accordingly. Here, the connection position of the first end of the connecting rod 35 with the rotating member 34 deviates from the rotation axis, and the second end is rotatably connected to the horizontal connecting member 313. Therefore, when the driving shaft drives the rotating member 34 to rotate, the connecting rod 35 will drive the horizontal connecting member 313 to reciprocate left and right, and the horizontal connecting member 313 drives the first partition 312 to reciprocally shake around the connection part between them and the hopper 10. In a specific technical solution, reference Figures 2 - 4, the second end of the connecting rod 35 is connected to the upper and lower loading rack 31 through a rotating shaft, and the connecting rod 35 is arranged on one side of the back surface 122 of the hopper.

[0038] Reference Figure 1 and Figure 6 , in an embodiment of the present application, above the upper and lower loading rack 31, a plurality of material blocking bodies 15 are further arranged in the material chute 11. When the fireworks inner cylinders in the material chute 11 fall, the material blocking bodies 15 can be used to provide blocking and buffering, reduce the aggregation and extrusion effect between the fireworks inner cylinders in the material chute 11, and make the falling of the fireworks inner cylinders smoother. As Figure 6 shown, above the upper and lower loading rack 31, three cylindrical material blocking bodies are arranged in the material chute 11.

[0039] Continue to refer to Figure 5 , in an embodiment of the present application, the pusher mechanism 40 includes a pusher frame 41 and a second driving source 42; a plurality of pusher members 411 corresponding to the plurality of discharge chutes 20 one by one are arranged on the pusher frame 41; as the second driving source 42 drives the pusher frame 41 to move back and forth, the plurality of pusher members 411 push out the fireworks inner cylinders in the plurality of discharge chutes 20. Specifically, the plurality of discharge chutes 20 extend in the same direction and are arranged horizontally at the bottom of the lower loading rack 32, and the plurality of pusher members 411 correspond to the plurality of discharge chutes 20 one by one. Further, the plurality of lower discharge channels 321 correspond to the plurality of discharge chutes 20 one by one, the plurality of upper and lower loading channels 311 correspond to the plurality of lower discharge channels 321 one by one, and the fireworks inner cylinders in the material chute 11 continuously fall into all the discharge chutes 20 after passing through the upper and lower loading channels 311 and the lower discharge channels 321.

[0040] When the second driving source 42 drives the pusher frame 41 to move forward, multiple pusher members 411 thereon simultaneously push the inner tubes of fireworks in multiple discharge chutes 20 forward. After pushing the inner tubes of fireworks in the discharge chutes 20 forward, the second driving source 42 drives the pusher frame 41 to retreat to the initial position. At the same time, after the inner tubes of fireworks in the discharge chutes 20 are pushed out by the pusher members 411, the inner tubes of fireworks in the lower blanking channel 321 will undergo a blanking operation to replenish the discharge chutes 20, so that the discharge chutes 20 are filled with inner tubes of fireworks. At this time, after the replenishing blanking, the second driving source 42 can drive the pusher frame 41 to push the materials forward again. Further, after the lower blanking channel 321 undergoes a blanking operation, the inner tubes of fireworks in the upper blanking channel 311 will undergo a blanking operation to replenish the lower blanking channel 321; after the inner tubes of fireworks in the upper blanking channel 311 undergo a blanking operation, the inner tubes of fireworks in the hopper 11 will undergo a blanking operation to replenish the upper blanking channel 311. Therefore, during the process that the second driving source 42 drives the pusher frame 41 to move back and forth continuously to push the inner tubes of fireworks in the discharge chutes 20 forward, the inner tubes of fireworks in the hopper 11 can continuously fall into the discharge chutes 20 through the upper blanking channel 311 and the lower blanking channel 321. In an embodiment of the present application, the second driving source 42 can be a cylinder.

[0041] Reference Figure 1 and Figure 2 , in an embodiment of the present application, the hopper 10 has an inclined side plate 12. The two sides of the side plate 12 are respectively the front side 121 and the back side 122, and the side plate 12 is inclined towards the back side 122; the upper blanking frame 31 and the lower blanking frame 32 are arranged on the front side 121 of the side plate 12; the side plate 12 is provided with dust dropping holes 13 in the area where the upper blanking channel 311 is located. Further, the dust dropping holes 13 are in a long strip shape and extend in the up and down direction; multiple rows of dust dropping holes 13 are arranged on the side plate 12.

[0042] It should be noted that the powder that can leak out from the inner tubes of fireworks, such as solid primers, sealing mud, etc., will fall downward into the upper blanking channel 311, the lower blanking channel 321, and the discharge chutes 20, which may have an adverse effect on the blanking and pushing of the inner tubes of fireworks, and may cause jamming of the inner tubes of fireworks in severe cases. In the embodiment of the present application, the hopper 10 is arranged in an inclined manner, inclined towards the back side 122, and the side plate 12 is provided with dust dropping holes 13 in the area where the upper blanking channel 311 is located. When the first driving source 33 is used to drive the upper blanking frame 31 to vibrate, the powder leaked from the inner tubes of fireworks can fall into the back side 122 of the side plate 12 through the dust dropping holes 13, which can prevent it from having an adverse effect on the blanking and pushing of the inner tubes of fireworks. Further, a dust collecting groove 14 is provided on the back side 122 of the side plate 12. The dust collecting groove 14 can collect the dust falling out from the dust dropping holes 13, which can prevent it from entering the filling die of the inner tube and affecting the filling process.

[0043] The embodiment of the present application also provides a filling device for the inner tube of fireworks, and the filling device for the inner tube of fireworks has the inner tube discharging device of fireworks provided in the previous part. After the inner tube discharging device of fireworks pushes out the inner tube of fireworks, the filling structure of the filling device for the inner tube of fireworks can fill the inner tube of fireworks into the combined fireworks. For the description of related technical means and technical effects, reference can be made to the description of the inner tube discharging device of fireworks in the previous part, which will not be elaborated here.

[0044] In the embodiment of the present application, the blanking assembly includes an upper blanking rack and a lower blanking rack. A plurality of upper blanking channels are provided on the upper blanking rack, and a plurality of lower blanking channels are provided on the lower blanking rack. The inner tubes of fireworks in the material trough sequentially pass through the upper blanking channels and the lower blanking channels and fall into the discharging chute below. By driving the upper blanking rack to vibrate through the first driving source, the blanking process of the inner tubes of fireworks can be made smoother, reducing jams and lowering safety risks. In addition, the inner tube discharging device of fireworks can also fully pass the powder leaked from the inner tubes of fireworks through the ash-dropping holes into the back side of the side plate, preventing it from having an adverse effect on the blanking and pushing of the inner tubes of fireworks.
