[0020] The following are specific embodiments of the present invention, which, in conjunction with the accompanying drawings, provide a further complete and clear description of the technical solution of the present application.

[0021] refer to Figures 1 - 3, the feeding device of the inner cylinder filling machine for fireworks includes adjacent first hopper 100 and second hopper 200 installed on the frame. There is a spacing between the first hopper 100 and the second hopper 200. The hopper walls 102 of the first hopper 100 and the hopper walls 202 of the second hopper 200 are set to be transparent for easy observation of the working state of the inner cylinder 40 of the fireworks. The interiors of the first hopper 100 and the second hopper 200 are partitioned into multiple hopper slots 101 and 201. A moving base 50 is arranged at the bottoms of the first hopper 100 and the second hopper 200. Multiple limiting slots 51 are provided on the moving base 50. The two sides of the moving base 50 are connected in cooperation with guide rails 57 and are connected to two conveyor belts 52. The two conveyor belts 52 are connected by four synchronous wheels 54 and two transmission shafts. The output shaft of the servo motor 53 is connected to the transmission shaft to enable the moving base 50 to reciprocate between the first area 55 and the second area 56 along the guide rails 57.

[0022] Extension parts 103 and 203 are respectively arranged at the bottoms of each hopper slot 101 and 201. The inner diameters of the extension parts 103 and 203 are set to only allow one inner cylinder of the fireworks to pass through, so as to facilitate the sequential arrangement of the inner cylinders 40 of the fireworks in the extension parts.

[0023] At one side of the top of the bottom of each hopper slot 101 and 201 and the extension parts 103 and 203, a polygonal stirring wheel 105 and a stirring wheel 205 are arranged respectively. The stirring ends of the stirring wheels 105 and 205 extend into the hopper slots 101 and 201. The stirring wheels 105 arranged at the bottom of each hopper slot 101 are sequentially installed on the rotating shafts, and the rotating shafts are connected to the second driving motor 106. The stirring wheels 205 arranged at the bottom of each hopper slot 201 are sequentially installed on another rotating shaft, and the rotating shafts are connected to the second driving motor 206. The side walls of the stirring wheels 105 and 205 are concave into an arc shape, which is consistent with the circular shape of the inner cylinder 40 of the fireworks, so as not to cause extrusion when stirring the inner cylinders of the fireworks and reduce damage to the inner cylinders of the fireworks. According to different production requirements for filling the inner cylinders of the fireworks, each hopper slot 101 and 102 may not be provided with an extension part, and the stirring wheels 105 and 205 can be installed at appropriate positions on the side walls at the outlet ends of the hopper slots.

[0024] A partition 60 is provided between the discharge ports of the first hopper 100 and the second hopper 200 and the moving base 50. The partition 60 is provided with a feeding channel (not shown in the figure) corresponding to the hopper slot discharge port. For example, if extension parts 103 and extension parts 203 are provided at the bottoms of each hopper slot 101 and 201, the partition 60 is located below the discharge ports of the extension parts 103 and extension parts 203.

[0025] On one side of the discharge openings of the first hopper 100 and the second hopper 200, there are respectively a push plate 107 and a push plate 207. The two ends of the push plate 107 and the push plate 207 are respectively connected to a third driving member, a cylinder 108 and a cylinder 208. Only the cylinder 108 and the cylinder 208 are drawn in the figure. At the other ends of the push plate 107 and the push plate 207, a cylinder corresponding to the cylinder 108 and the cylinder 208 is respectively connected. Due to the large areas of the first hopper 100 and the second hopper 200, multiple material grooves are provided, and the length of the push plate is the same as the length of the hopper. For the purpose of achieving uniform material pushing, two cylinders are provided at the head and tail ends of the push plate. In actual production, if the area of the hopper is small, only one driving member can be provided at the middle position of the push plate.

[0026] When the blanking device of the fireworks inner tube filling machine is working, the staff place the fireworks inner tubes 40 filled with colored agents in the material groove 101 and place the fireworks inner tubes 40 filled with whistling agents in the material groove 201. The inner tubes 40 are stacked in the material groove 101 and the material groove 201.

[0027] The servo motor 53 drives the moving base 50 to move to a predetermined position in the first area 55. The stirring wheels 105 and 205 rotate respectively driven by the motors 106 and 206 to stir and mix the fireworks inner tubes in each material groove, preventing the fireworks inner tubes from getting stuck at the discharge opening. The fireworks inner tubes 40 fall into the extension parts 103 and 203 in sequence under the agitation of the stirring wheels 105 and 205. The length of the extension part can be set according to production requirements.

[0028] When the fireworks inner tubes 40 at the bottom ends of the extension parts 103 and 203 fall onto the partition plate 60, the push plate 107 and the push plate 207 drive the fireworks inner tubes 40 into the partition plate blanking channel 61 under the drive of the cylinder 108 and the cylinder 208, and then fall into the limit groove 51 on the moving base 50. The thickness of the push plate 107 and the push plate 207 is slightly smaller than the diameter of the fireworks inner tube 40. When the push plate 107 and the push plate 207 move forward, the bottom ends of the extension parts 103 and 203 are respectively closed by the push plate 107 and the push plate 207, which can ensure that there is no extrusion and dislocation between the fireworks inner tubes 40 in two layers.

[0029] After the moving base 50 completes the filling of a row of fireworks inner tubes, the servo motor 53 drives the moving base 50 to displace, the cylinder 108 and the cylinder 208 respectively retract backward, the push plate 107 and the push plate 207 retract backward, and the fireworks inner tubes 40 whose bottom ends of the extension parts 103 and 203 are closed by the push plate 107 and the push plate 207 fall onto the partition plate 60. The cylinder 108 and the cylinder 208 are pushed forward again, and the inner tube blanking action is completed by repeating in sequence.

[0030] The blanking of the inner tubes of the fireworks in the hopper 101 and the hopper 201 is preset according to the requirements of the fireworks display design. The push plates 107 and 207 push the inner tubes of the fireworks into the partition blanking channel 61 row by row according to the preset actions, and then fall into the limit slots 51 on the moving base 50 to complete the filling of the inner tubes. When the filling of the inner tubes of the fireworks in all the limit slots 51 of the moving base 50 is completed according to the preset actions, the moving base 50 is driven by the servo motor 53 to move from the first area 55 to the second area 56, and the inner tubes of the fireworks in the limit slots 51 are removed by the mold moving device of the inner tube filling machine for fireworks.
