In addition, in order to be clear and concise, the description of known functions and structures is omitted.

[0050] It should be noted that the embodiments and features in the embodiments can be combined with each other without conflict.

[0051] 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 ribbons, in a hexagonal shape, and the two ends of the ribbon are connected together by a rubber band.

Specifically, the two ends of the ribbon P1 are provided with hook-shaped structures, and the rubber band P2 connects the two ends of the ribbon P1 by hanging on the hook-shaped structures at the two ends of the ribbon P1.

[0052] The feeding assembly for the inner tube of the firework provided by the present application is applied to a combined firework production device, can feed the inner tube to a plurality of troughs of a hopper, and can facilitate the separation of man and machine, and is high in safety.

[0053] Reference Figures 2-4The feeding assembly comprises a rack 100, a moving base 200, a cake pushing mechanism 50, a cable removing assembly 300, a hopper 60, a fifth driving unit 70, and a cylinder pushing mechanism 80. The moving base 200 is provided with a slide 201 adapted to the inner cylinder cake P, and a transfer bin 202 is arranged at the end of the slide 201. The cake pushing mechanism 50 is assembled on the moving base 200 and used to push the inner cylinder cake P in the slide 201 forward into the transfer bin 202. The cable removing assembly 300 is assembled on the moving base 200 and used to remove the cable of the inner cylinder cake P in the transfer bin 202. The hopper 60 is arranged beside the transfer bin 202, and a plurality of troughs 61 are arranged in the moving direction of the moving base 200. The fifth driving unit 70 is used to drive the moving base 200 to move relative to the rack 100 so that the transfer bin 202 is aligned with any one of the troughs 61 on the hopper 60. The cylinder pushing mechanism 80 is assembled on the moving base 200 and used to push the inner cylinder in the transfer bin 202 laterally into the aligned trough 61.

[0054] In operation, the inner cylinder cake P is first placed on the slide 201, and the cake pushing mechanism 50 pushes the inner cylinder cake P along the slide 201 to the transfer bin 202 at the end of the slide 201. At the position of the transfer bin 202, the cable removing assembly 300 removes the cable P1 of the inner cylinder cake P, leaving only the inner cylinder P3. The cylinder pushing mechanism 80 can push the inner cylinder in the transfer bin 202 laterally into the aligned trough 61.

[0055] The fifth driving unit 70 can drive the moving base 200 to move relative to the rack 100 so that the transfer bin 202 is aligned with any one of the troughs 61 on the hopper 60. Therefore, the inner cylinder in the transfer bin 202 can be pushed by the cylinder pushing mechanism 80 into any one of the troughs 61 on the hopper 60. The hopper 60 is provided with a plurality of partitions distributed at intervals, and a trough 61 is formed between adjacent partitions. In Figure 4 In the structure shown in the drawings, the hopper 60 has eight troughs, and the transfer bin 202 can be aligned with any one of the eight troughs as the fifth driving unit 70 drives the moving base 200 to move relative to the rack 100.

[0056] Reference Figure 2 and Figure 3 The moving base 200 is provided with a slide 201 adapted to the inner cylinder cake P, and a transfer bin 202 is arranged at the end of the slide 201. The slide 201 can support the inner cylinder cake P to slide thereon in a predetermined direction and can be designed in various structural forms. In Figure 3 In the structure shown in the drawings, the slide 201 is a plate structure comprising a bottom plate and side plates on both sides of the bottom plate, and the inner cylinder cake P is erected on the slide 201.

[0057] The transfer bin 202 is located at the end of the slide 201 and is used to accommodate the inner cylinder cake P. It should be understood that the transfer bin 202 here only represents a position at the end of the slide 201 that can accommodate the inner cylinder cake P and can receive the inner cylinder cake pushed by the slide 201, and does not require a closed or semi-closed internal space to be formed.

[0058] In an embodiment of the present application, the cake pushing mechanism 50 comprises a pushing frame 51, a screw transmission mechanism, and a sixth driving unit 54. The sixth driving unit 54 is mounted on the moving base 200 and is in power connection with the screw rod 52 of the screw transmission mechanism to drive the screw rod 52 of the screw transmission mechanism to rotate. The pushing frame 51 is connected with the screw nut 53 of the screw transmission mechanism. When the sixth driving unit 54 drives the screw rod 52 of the screw transmission mechanism to rotate, the screw nut 53 of the screw transmission mechanism drives the pushing frame 51 to move, so that the pushing frame 51 pushes the inner cylinder cake in the slide 201 forward.

[0059] The screw transmission mechanism comprises a screw rod 52 and a screw nut 53, and can accurately convert the rotary motion of the screw rod into the linear motion of the screw nut. When the sixth driving unit 54 drives the screw rod 52 to rotate, the screw nut 53 can drive the pushing frame 51 to move along the extension direction of the screw rod 52. In a specific scheme, the sixth driving unit 54 is a motor.

[0060] In an embodiment of the present application, the cylinder pushing mechanism 80 comprises a side pushing frame 81 and a seventh driving unit 82. The seventh driving unit 82 is connected with the side pushing frame 81 and can drive the side pushing frame 81 to laterally push the inner cylinder in the transfer bin 202 into the hopper 61 aligned therewith. The seventh driving unit 82 can be a pneumatic cylinder and can drive the side pushing frame 81 to move telescopically, so as to laterally push the inner cylinder in the transfer bin 202 into the hopper 61 aligned therewith. In some technical solutions, the front part of the side pushing frame 81 is provided in a V shape.

[0061] The fifth driving unit 70 is used to drive the moving base 200 to move relative to the rack 100, so that the transfer bin 202 is aligned with any one of the hoppers 61 on the hopper 60. In Figure 2 In the structure shown, the fifth driving unit 70 is a motor and can drive the moving base 200 to move relative to the rack 100 through a screw transmission mechanism.

[0062] Reference Figure 5 The cable removal assembly comprises a cable opening mechanism 10 and a cable hooking mechanism 40. The cable opening mechanism can unfasten the rubber band P2 connecting the two ends of the cable P1 on the inner cylinder cake P, so that the two ends of the cable P1 can be separated from each other. The cable hooking mechanism 40 can hook away the cable P1 from around the inner cylinder P3 after the rubber band P2 of the cable P1 is unfastened, so as to separate the cable P1 of the inner cylinder cake P from the inner cylinder. In an embodiment of the present application, the cable opening mechanism 10 is arranged above the inner cylinder cake P, and the cable hooking mechanism 40 is arranged below the inner cylinder cake P.

[0063] In operation, the elastic band opening mechanism 10 first opens the elastic band P2, so that the two ends of the elastic band P1 can be separated from each other. Then, the elastic band hooking mechanism 40 hooks the elastic band P1 from the periphery of the inner cylinder P3, so that the elastic band of the inner cylinder cake is separated from the inner cylinder. Therefore, the elastic band removing assembly can automatically remove the elastic band of the inner cylinder cake, replacing the manual removal of the elastic band of the inner cylinder cake, so as to realize automatic feeding, high automation and high safety of personnel.

[0064] In an embodiment of the present application, referring to Figure 6 and Figure 7 The elastic band opening mechanism 10 comprises a first action sub-mechanism 20. The first action sub-mechanism 20 comprises a moving head 21 and a first driving unit 22. The first driving unit 22 is configured to drive the moving head 21 to act, so that the moving head 21 is inserted into the inner circle of the elastic band P2 and winds the elastic band P2 out of the hook-shaped structure at one end of the elastic band.

[0065] The first driving unit 22 drives the moving head 21 to move along a predetermined trajectory. With the action of the moving head 21, the moving head 21 is inserted into the inner circle of the elastic band P2 and winds the elastic band P2 out of the hook-shaped structure at one end of the elastic band. It should be understood that the first driving unit 22 can be composed of one or more sub-driving units.

[0066] In an embodiment of the present application, the first driving unit 22 comprises a first sub-driving unit 221 and a second sub-driving unit 222. The first sub-driving unit 221 is configured to drive the moving head 21 to move, so that the moving head 21 is inserted into or withdrawn from the inner circle of the elastic band P2. The second sub-driving unit 222 is configured to drive the moving head 21 to eccentrically rotate in the inner circle of the elastic band P2, so that the moving head 21 winds the elastic band P2 out of the hook-shaped structure at one end of the elastic band.

[0067] In operation, the first sub-driving unit 221 first drives the moving head 21 to move downward, and the moving head 21 is inserted into the inner circle of the elastic band P2. Then, the second sub-driving unit 222 drives the moving head 21 to eccentrically rotate in the inner circle of the elastic band P2, and the moving head 21 winds the elastic band P2 out of the hook-shaped structure at one end of the elastic band P1. Finally, the first sub-driving unit 221 drives the moving head 21 to move upward, and the moving head 21 is withdrawn from the inner circle of the elastic band P2. At this time, the elastic band P2 connecting the two ends of the elastic band P1 is opened.

[0068] In an embodiment of the present application, the first action sub-mechanism 20 further comprises a moving bracket 23; the moving bracket 23 is assembled on the first sub-driving unit 221; the second sub-driving unit 222 is assembled on the moving bracket 23. Two pressing rods 24 are further arranged on the moving bracket 23, and the two pressing rods 24 are respectively located on two sides of the moving head 21; when the first sub-driving unit 221 drives the moving head 21 to insert into the inner ring of the rubber band P2, the heads 241 of the two pressing rods 24 respectively press the two ends of the cable tie. Further, an elastic element 25 is arranged between the moving bracket 23 and the pressing rod 24; when the first sub-driving unit 221 drives the moving head 21 to insert into the inner ring of the rubber band P2, the moving bracket 23 pushes the head 241 of the pressing rod 24 to press the cable tie P1 through the elastic element 25.

[0069] Specifically, the first sub-driving unit 221 is a pneumatic cylinder, which can drive the moving bracket 23 to move up and down; the second sub-driving unit 222 is a motor, which can drive the moving head 21 to eccentrically rotate. The second sub-driving unit 222 and the pressing rod 24 are arranged on the moving bracket 23. In operation, as the first sub-driving unit 221 drives the moving bracket 23 to move downward, the moving head 21 is inserted into the inner ring of the rubber band P2 downward, and at the same time, the heads 241 of the two pressing rods 24 respectively press the two ends of the cable tie P1. Here, as the two ends of the cable tie P1 are pressed by the two pressing rods 24, when the second sub-driving unit 222 drives the moving head 21 to eccentrically rotate in the inner ring of the rubber band P2, the cable tie P1 will not move. Further, the elastic element 25 is a spring, which is arranged between the moving bracket 23 and the pressing rod 24. As the head 241 of the pressing rod 24 moves downward and comes into contact with the cable tie P1, the cable tie P1 can compress the elastic element 25 by pressing the pressing rod 24 upward, and finally, the pressing rod 24 presses the cable tie P1 downward through the elastic element 25.

[0070] In an embodiment of the present application, referring to Figure 8 and Figure 9 , the cable tie opening mechanism 10 further comprises a second action sub-mechanism 30; the second action sub-mechanism 30 is used to drive the two ends of the cable tie to be staggered with each other along the axial direction of the inner cylinder P3 before the moving head 21 is inserted into the inner ring of the rubber band P2, so as to expand the inner ring of the rubber band P2. When the two ends of the cable tie are staggered with each other along the axial direction of the inner cylinder P3, the area of the inner ring of the rubber band P2 is increased, so that the moving head 21 can be more easily inserted into the inner ring of the rubber band P2.

[0071] The second action sub-mechanism 30 comprises a first top rod 31, a second top rod 32, and a second driving unit 33. The second driving unit 33 is configured to drive the first top rod 31 and the second top rod 32 to move forward and backward along the axial direction of the inner cylinder. The first top rod 31 and the second top rod 32 are located on the same side of the rubber band, and the ends of the first top rod 31 and the second top rod 32 are staggered in the moving direction, so that when the first top rod 31 and the second top rod 32 respectively abut against the two ends of the rubber band, the two ends of the rubber band can be staggered along the axial direction of the inner cylinder. The second driving unit 33 can be a pneumatic cylinder. When the second driving unit 33 extends forward, the ends of the first top rod 31 and the second top rod 32 move forward synchronously to abut against the two ends of the rubber band P1. At this time, due to the staggered arrangement of the ends of the first top rod 31 and the second top rod 32 in the moving direction, the two ends of the rubber band P1 are staggered along the axial direction of the inner cylinder P3.

[0072] In an embodiment of the present application, referring to Figure 10 and Figure 11 The rubber band hooking mechanism 40 comprises a hook-shaped member 41 and a third driving unit 42. The hook-shaped member 41 is configured to hook between the rubber band and the inner cylinder of the inner cylinder pie. When the hook-shaped member 41 hooks between the rubber band and the inner cylinder of the inner cylinder pie, the third driving unit 42 can drive the hook-shaped member 41 to retreat with the rubber band hooked to take the rubber band away from around the inner cylinder after the rubber band is unwound by the rubber band. In operation, the hook-shaped member 41 hooks between the rubber band P1 and the inner cylinder P3 of the inner cylinder pie P. At this time, as the third driving unit 42 drives the hook-shaped member 41 to retreat, the hook-shaped member 41 retreats with the rubber band P1 hooked to take the rubber band P1 away from around the inner cylinder P3 after the rubber band P1 is unwound by the rubber band P2.

[0073] The rubber band hooking mechanism 40 further comprises an intermediate support 43, a fourth driving unit 44, and a pressing head 45. The intermediate support 43 is assembled on the third driving unit 42. The hook-shaped member 41 is assembled on the intermediate support 43. The fourth driving unit 44 is assembled on the intermediate support 43. The pressing head 45 is assembled on the fourth driving unit 44. The third driving unit 42 can synchronously drive the hook-shaped member 41 and the fourth driving unit 44 to move through the intermediate support 43. When the hook-shaped member 41 hooks between the rubber band and the inner cylinder of the inner cylinder pie, the fourth driving unit 44 can drive the pressing head 45 to move forward to approach the hook-shaped member 41 to press the rubber band P1 between the pressing head 45 and the hook-shaped member 41.

[0074] Specifically, the third driving unit 42 and the fourth driving unit 44 are both air cylinders. The hook-shaped member 41 and the fourth driving unit 44 are both assembled on the middle support 43. When the hook-shaped member 41 hooks into the strap and the inner cylinder of the inner cylinder pie, the fourth driving unit 44 can drive the pressure head 45 to move forward relative to the hook-shaped member 41, and the pressure head 45 close to the hook-shaped member 41 can press the strap P1 between the pressure head 45 and the hook-shaped member 41. When the third driving unit 42 retracts, the pressure head 45 and the hook-shaped member 41 retreat synchronously, the strap P1 between the pressure head 45 and the hook-shaped member 41 is extracted synchronously, and the strap P1 is separated from the inner cylinder P3. In this design, the strap P1 is pressed between the pressure head 45 and the hook-shaped member 41, which can avoid the strap P1 from being separated from the hook-shaped member 41 when the hook-shaped member 41 retreats, and the action is more reliable.

[0075] Based on the above description, the strap removal assembly provided in the present application can include the following action process when working. Step A, the inner cylinder pie P enters the predetermined position. Step B, the second action sub-mechanism 30 drives the two ends of the strap to be staggered along the axial direction of the inner cylinder P3 to expand the inner circle of the rubber band P2 (the second driving unit 33 drives the first top rod 31 and the second top rod 32 to respectively press against the two ends of the strap, and the two ends of the strap are staggered along the axial direction of the inner cylinder). Step C, the first sub-driving unit 221 drives the moving support 23 to move downward, and the movement head 21 is inserted into the inner circle of the rubber band P2 downward, and at the same time, the heads 241 of the two pressure rods 24 press against the two ends of the strap P1 respectively. Step D, the second sub-driving unit 222 drives the movement head 21 to eccentrically rotate in the inner circle of the rubber band P2, and the movement head 21 winds the rubber band P2 out of the hook-shaped structure of one end of the strap P1.
