DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present application and further describe the technical solutions of the present application in conjunction with the drawings, 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, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, in order to be clear and concise, the description of known functions and structures is omitted.

[0034] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0035] The inner tube cake is the basic unit of firework production, and the inner tube cake is composed of a plurality of inner tubes combined by a strap, and is a hexagon. Figure 6 The structure of an inner tube cake is schematically shown, which includes an inner tube 51 and a strap 52, and the inner tube 51 is bundled by the strap 52, and is a hexagon.

[0036] The feeding assembly of the firework inner tube provided by the present application is applied to the automatic production equipment of the firework, and the automatic feeding of the inner tube can be performed, and the worker does not need to approach the stock bin for the feeding operation of the inner tube during production, and the safety is high.

[0037] Reference Figure 1 The feeding assembly of the firework inner tube includes a stock bin 10, an inner tube cake feeding mechanism 20, an inner tube cake transfer mechanism 30, and an inner tube pushing mechanism 40. The inner tube cake transfer mechanism 30 includes a transfer frame 31 and a first driving unit 32. The transfer frame 31 is provided with a plurality of material frames. The first driving unit 32 can drive the transfer frame 31 to move, so that the material frame moves to a first position and a second position. When the material frame is located at the first position so that the material frame is aligned with the inner tube cake feeding mechanism 20, the inner tube cake feeding mechanism 20 can load the inner tube cake into the material frame. When the material frame is located at the second position so that the material frame is aligned with the stock bin 10, the inner tube pushing mechanism 40 can push the inner tubes contained in the inner tube cake in the material frame into the stock bin 10.

[0038] During feeding, the worker can place the inner tube cake on the inner tube cake feeding mechanism 20. First, the first driving unit 32 drives the transfer frame 31 to move, so that the material frame moves to the first position, and the material frame is aligned with the inner tube cake feeding mechanism 20. The inner tube cake feeding mechanism 20 loads the inner tube cake into the material frame. Then, the first driving unit 32 drives the transfer frame 31 to move, so that the material frame moves to the second position, and the material frame is aligned with the stock bin 10. The inner tube pushing mechanism 40 pushes the inner tubes contained in the inner tube cake in the material frame into the stock bin 10. In this way, through the inner tube cake feeding mechanism 20, the inner tube cake transfer mechanism 30, and the inner tube pushing mechanism 40, the inner tubes of the inner tube cake are loaded into the stock bin, the degree of automation is high, and the worker does not need to approach the stock bin for the feeding operation of the inner tube during production, and the safety is high.

[0039] Reference Figure 2 and Figure 3 In an embodiment of the present application, the inner tube cake feeding mechanism 20 comprises a support 21 and an inner tube cake pushing sub-mechanism 22. The support 21 is provided with a chute 211 which is adapted to the shape of the inner tube cake; the chute 211 can be aligned with the frame when the frame is in the first position. The inner tube cake pushing sub-mechanism 22 is assembled on the support 21 and is used to push the inner tube cake in the chute 211 into the frame. During production, the worker or the mechanism puts the inner tube cake into the chute 211. When the frame is in the first position, the chute 211 is aligned with the frame, and the inner tube cake pushing sub-mechanism 22 can push the inner tube cake in the chute 211 into the frame.

[0040] The inner tube cake pushing sub-mechanism 22 is used to push the inner tube cake in the chute 211. It should be understood that the pushing mechanism is extremely common in fireworks production equipment and automated production equipment, and generally comprises a pushing piece and a driving device, which can be an electric device or a pneumatic device, and is used to drive the pushing piece to move along the chute 211 to push the inner tube cake in the chute 211. For example, the driving device can adopt a belt device, the pushing piece is fixed on the belt of the belt device, and when the belt device operates, the belt of the belt device can drive the pushing piece to move along the chute 211 to push the inner tube cake in the chute 211. For another example, the driving device can adopt a pneumatic cylinder, the pushing piece is connected with the piston rod of the pneumatic cylinder, and when the piston rod of the pneumatic cylinder extends and retracts, it drives the pushing piece to move along the chute 211 to push the inner tube cake in the chute 211.

[0041] The inner tube cake feeding mechanism 20 further comprises a second driving unit 23; the second driving unit 23 is used to drive the support 21 to move, so that the chute 211 approaches or moves away from the frame. In the state that the frame is in the first position, the second driving unit 23 can drive the support 21 to move so that the chute 211 approaches the frame, and the inner tube cake feeding mechanism 20 loads the inner tube cake into the frame. After the frame in the first position is loaded with the inner tube cake, the second driving unit 23 drives the support 21 to move so that the chute 211 moves away from the frame, at this time, the first driving unit 32 drives the transfer frame 31 to move to move away the frame in the first position. This design can avoid the interference of the chute 211 with the movement of the transfer frame 31. Further, the second driving unit 23 can adopt an electric device or a pneumatic device, and can be specifically provided as a pneumatic cylinder, an electric cylinder, etc.

[0042] In an embodiment of the present application, the shape and size of the hopper 10 are adapted to the inner tube cake. When the inner tube pushing mechanism 40 pushes the inner tube of the inner tube cake into the hopper 10, since the shape and size of the hopper 10 are adapted to the inner tube cake, the shape and size of the hopper can just accommodate the inner tube of the inner tube, which can well limit the inner tube to avoid rolling and disorder.

[0043] In the technical solution of the present application, the inner cylinder cake transferring mechanism 30 comprises a transferring frame 31 and a first driving unit 32 capable of driving the transferring frame 31 to move. The first driving unit 32 can be an electric device, a pneumatic device, etc. The movement of the transferring frame 31 can be designed as translation or rotation.

[0044] In an embodiment of the present application, referring to Figure 1 , the material frame has opposite first side A and second side B; when the inner cylinder cake passes through the material frame from the first side A to the second side B, the material frame can block the cable tie of the inner cylinder cake and allow the inner cylinder of the inner cylinder cake to pass through. When the material frame is located at the first position, the inner cylinder cake loading mechanism 20 is located at the first side of the material frame to load the inner cylinder cake into the material frame from the first side of the material frame; when the material frame is located at the second position, the material bin 10 is located at the second side of the material frame, and the inner cylinder contained in the inner cylinder cake in the material frame is loaded into the material bin 10 from the second side of the material frame. In an embodiment of the present application, a plurality of material blocking pieces are arranged around the material frame, and when the inner cylinder pushing mechanism 40 pushes the inner cylinder of the inner cylinder cake in the material frame to the material bin 10, the material blocking pieces can block the cable tie of the inner cylinder cake to separate the cable tie from the inner cylinder.

[0045] In operation, first, the first driving unit 32 drives the transferring frame 31 to move to the first position, and the inner cylinder cake loading mechanism 20 loads the inner cylinder cake into the material frame from the first side of the material frame. Then, the first driving unit 32 drives the transferring frame 31 to move to the second position, and under the driving of the inner cylinder pushing mechanism 40, the inner cylinder contained in the inner cylinder cake in the material frame is loaded into the material bin 10 from the second side of the material frame. Since the material frame can block the cable tie of the inner cylinder cake and allow the inner cylinder of the inner cylinder cake to pass through, when the inner cylinder pushing mechanism 40 pushes the inner cylinder of the inner cylinder cake in the material frame to the second side of the material frame, the inner cylinder is separated from the cable tie and then enters the material bin 10, without the need for manual removal of the cable tie.

[0046] Referring to Figure 4 and Figure 5 , a plurality of pressing pieces 312 are arranged around the material frame, and the plurality of pressing pieces 312 respectively expand to the periphery of the material frame toward the first side of the material frame. Each pressing piece 312 is configured with an elastic piece, and the elastic piece acts on the pressing piece 312 to press the pressing piece 312 into the inner cylinder cake in the material frame. When the inner cylinder cake pushing sub-mechanism 22 pushes the inner cylinder cake in the slide 211 from the first side to the material frame, the pressing piece 312 can guide the inner cylinder cake into the material frame, and after the inner cylinder cake enters the material frame, the elastic piece can drive the pressing piece 312 to press the inner cylinder cake in the material frame.

[0047] In an embodiment of the present application, the first driving unit 32 drives the transfer frame 31 to rotate to move the frame on the transfer frame 31 to the first position and the second position. A plurality of frames are arranged in the circumferential direction around the transfer frame 31; with the rotation of the transfer frame 31, each frame on the transfer frame 31 is sequentially moved to the first position and the second position. Further, the angular distribution of the frames on the transfer frame 31 is such that during the rotation of the transfer frame 31, there are frames reaching the first position and the second position at the same time. In this way, the action of loading the inner cylinder cake into the frame and the action of pushing the inner cylinder into the magazine can be performed at the same time, effectively improving the working efficiency of the equipment.

[0048] Reference Figure 1 In an embodiment of the present application, the transfer frame 31 is provided with a first frame 311a and a second frame 311b, and the first frame 311a and the second frame 311b are arranged on both sides of the rotation axis of the transfer frame 31; the first position and the second position are arranged on both sides of the rotation axis of the transfer frame 31; during the rotation of the transfer frame 31, when the first frame 311a reaches the first position, the second frame 311b reaches the second position; when the first frame 311a reaches the second position, the second frame 311b reaches the first position. Therefore, while one of the frames is loading the inner cylinder cake at the first position, the other frame is outputting the inner cylinder to the magazine at the second position, in this way, the first frame 311a and the second frame 311b are alternately moved to the first position and the second position, and the action of loading the inner cylinder cake into the frame and the action of pushing the inner cylinder into the magazine are performed at the same time.

[0049] The embodiment of the present application also provides a firework production equipment, and the firework production equipment has the firework inner cylinder loading assembly provided in the foregoing part. The firework inner cylinder loading assembly comprises the magazine 10, the inner cylinder cake loading mechanism 20, the inner cylinder cake transfer mechanism 30 and the inner cylinder pushing mechanism 40. The inner cylinder cake transfer mechanism 30 comprises the transfer frame 31 and the first driving unit 32. The transfer frame 31 is provided with a plurality of frames. The first driving unit 32 can drive the transfer frame 31 to move so that the frame on the transfer frame 31 moves to the first position and the second position. When the frame is located at the first position and is aligned with the inner cylinder cake loading mechanism 20, the inner cylinder cake loading mechanism 20 can load the inner cylinder cake into the frame. When the frame is located at the second position and is aligned with the magazine 10, the inner cylinder pushing mechanism 40 can push the inner cylinder contained in the frame into the magazine 10. Through the inner cylinder cake loading mechanism 20, the inner cylinder cake transfer mechanism 30 and the inner cylinder pushing mechanism 40, the inner cylinder of the inner cylinder cake is loaded into the magazine, the automation degree is high, and the worker does not need to approach the magazine to perform the inner cylinder loading operation during production, and the safety is high.
