[0002] Firework inner tube filling equipment is a key specialized piece of equipment in fireworks and firecracker production. It is used to safely, accurately, and efficiently fill pre-made fireworks inner tubes (also known as "effect tubes" or "sub-tubes") into the fireworks pellets (also known as "outer tubes," "launch tubes," "bases," or "mother tubes"). Typically, the inner tube cake is the basic unit of fireworks production. The inner tube cake is composed of multiple inner tubes assembled together by tie-down straps, forming a hexagonal shape.

[0018] Optionally, the hook structure includes a telescopic rod and a hook component; the elastic element acts on the telescopic rod; the hook component is assembled at the front of the telescopic rod.

[0019] When the elastic element drives the telescopic rod to pop forward, the hook can rotate backward to enter the inner circle of the cable tie; when the second drive source drives the first pusher to retract, the hook can hook the cable tie and retract synchronously.

[0020] Optionally, the front of the first pusher is configured as a V-shaped groove, and the hook structure is arranged in the middle of the V-shaped groove.

Detailed Implementation

[0034] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0036] The technical advantage of this application lies in realizing a cake-unpacking mechanism that can automatically separate the inner cylinder from the cable tie without manual operation of cake unpacking and feeding, thereby improving the safety and efficiency of fireworks production equipment.

[0037] refer to Figures 1-3 The fireworks inner tube unpacking mechanism includes a first platform 10, a second platform 20, an upper lifting mechanism 30, a first pushing mechanism 40, and a second pushing mechanism 60. The first platform 10 has a first notch 11. The second platform 20 has a second notch 21; the second platform 20 is located above the first platform 10; the second notch 21 and the first notch 11 are aligned. The upper lifting mechanism 30 includes a lifting head 31 and a first drive source 32; the lifting head 31 is aligned with the first notch 11 and the second notch 21; the first drive source 32 can drive the lifting head 31 to move down to a first height position or up to a second height position.

[0038] When the lifting head 31 is at the first height position, the first pushing mechanism 40 can push the inner cylinder cake on the first platform 10 above the lifting head 31 and align it with the second notch 21. As the lifting head 31 moves up to the second height position, the inner cylinder of the inner cylinder cake moves upward through the second notch 21 to the top of the second platform 20. The tie of the inner cylinder cake is blocked by the edge of the second notch 21, thereby separating the tie from the inner cylinder. When the lifting head 31 is at the second height position, the second pushing mechanism 60 can push the inner cylinder on the lifting head 31 onto the second platform 20.

[0039] refer to Figure 8 The inner cylinder cake 80 is composed of multiple inner cylinders 81 assembled together by tie straps 82, forming a hexagonal shape. When the equipment is working, firstly, refer to... Figure 5 and Figure 6 The inner cylinder cake 80 is placed on the first platform 10, and the first drive source 32 drives the lifting head 31 to move down to a first height position; then, the first pushing mechanism 40 pushes the inner cylinder cake on the first platform 10 above the lifting head 31 and aligns it with the position of the second notch 21. (Reference) Figure 7 As the first drive source 32 drives the lifting head 31 to move upward to the second height position, the inner cylinder 81 of the inner cylinder cake 80 moves upward through the second notch 21 and reaches above the second platform 20. The cable tie 82 of the inner cylinder cake 80 is blocked by the edge of the second notch 21, and the cable tie 82 is detached from the inner cylinder 81, leaving only the inner cylinder 81 above the second platform 20. At this time, the second pushing mechanism 60 can push the inner cylinder on the lifting head 31 onto the second platform 20.

[0040] As can be seen from the above working process, the inner cylinder cake 80 is fed to the first platform 10. After the above working process, the inner cylinder 81 of the inner cylinder cake 80 is separated from the tie 82, and only the inner cylinder 81 reaches the second platform 20, so that it can be subsequently filled into the fireworks launch tube. Therefore, the above-mentioned fireworks inner cylinder unpacking mechanism can automatically separate the inner cylinder from the tie, without the need for manual unpacking and feeding, which can improve the safety and efficiency of fireworks production equipment.

[0041] In one embodiment of this application, reference is made to Figure 5 and Figure 6 When the lifting head 31 is at the first height position, its top is aligned with the height of the first platform 10; Reference Figure 7 When the lifting head 31 is at the second height position, its top is aligned with the height of the second platform 20.

[0042] In one embodiment of this application, the fireworks inner tube unpacking mechanism further includes a positioning structure; the positioning structure is located in front of the first pushing mechanism 40; the positioning structure can position the inner tube cake pushed by the first pushing mechanism 40 so that the inner tube cake is aligned with the second notch 21. (Reference) Figure 6The positioning structure consists of multiple retaining edges 12; each retaining edge 12 corresponds to one of the multiple sides of the inner cylinder cake; when the inner cylinder cake pushed by the first pushing mechanism 40 abuts against each retaining edge 12, the inner cylinder cake is aligned with the second notch 21. Figure 6 In the structure shown, the positioning structure includes four baffles 12, which correspond to the four sides of the inner cylinder cake respectively. When the first pushing mechanism 40 pushes the inner cylinder cake 80 into the four baffles 12, the four baffles 12 abut against the four sides of the inner cylinder cake 80 respectively, so that the inner cylinder cake 80 is precisely positioned and aligned with the second notch 21.

[0043] In one embodiment of this application, the first pushing mechanism 40 includes a first pushing frame 41 and a second driving source 42. The second driving source 42 is used to drive the first pushing frame 41 to move, so that the first pushing frame 41 pushes the inner cylinder cake on the first platform 10 forward. The first pushing frame 41 is equipped with a hooking mechanism 50. When the second driving source 42 drives the first pushing frame 41 to retract, the hooking mechanism 50 can hook the cable tie that is separated from the inner cylinder, so that the cable tie retracts together with the first pushing frame 41.

[0044] Furthermore, the hooking mechanism 50 includes a hooking structure 51 and an elastic element 52; the elastic element 52 acts on the hooking structure 51; when the second drive source 42 drives the first pusher 41 to move forward, the inner cylinder cake abuts against the hooking structure 51 and forces the hooking structure 51 to overcome the retraction of the elastic element 52. After the inner cylinder of the inner cylinder cake moves upward and separates from the cable tie, the elastic element 52 can drive the hooking structure 51 to pop forward to hook the cable tie that has separated from the inner cylinder.

[0045] The second drive source 42 can drive the first pusher 41 to move back and forth. When the second drive source 42 drives the first pusher 41 to push the inner cylinder cake on the first platform 10 forward, the hook structure 51 comes into contact with the inner cylinder cake 80, and the inner cylinder cake 80 abuts against the hook structure 51, which can force the hook structure 51 to overcome the retraction of the elastic element 52. Furthermore, after the inner cylinder of the inner cylinder cake 80 moves upward and separates from the cable tie, the elastic element 52 can drive the hook structure 51 to pop forward to hook the cable tie that has separated from the inner cylinder.

[0046] Furthermore, the hook structure 51 includes a telescopic rod 511 and a hook component 512; an elastic element 52 acts on the telescopic rod 511; the hook component 512 is assembled at the front of the telescopic rod 511. When the elastic element 52 drives the telescopic rod 511 to extend forward, the hook component 512 can rotate backward to retract into the inner circle of the cable tie; when the second drive source 42 drives the first pusher 41 to retract, the hook component 512 can hook the cable tie and retract synchronously. It should be understood that the hook component 512 can only rotate backward relative to the telescopic rod 511, and will be stuck when moving forward. Therefore, when extending, the hook component 512 can rotate backward to retract into the inner circle of the cable tie, and when retracting, it can hook the cable tie and retract synchronously.

[0047] refer to Figure 4 The front part of the first pusher 41 is constructed as a V-shaped groove 411, and the hook structure 51 is arranged in the middle of the V-shaped groove 411. The elastic element 52 can be specifically set as a spring.

[0048] In one embodiment of this application, the second pushing mechanism 60 includes a second pushing frame 61 and a third driving source 62; the third driving source 62 is used to drive the second pushing frame 61 to move, so that the second pushing frame 61 pushes the inner cylinder on the second platform 20 forward. The fireworks inner cylinder unpacking mechanism also includes a blocking mechanism 70, which includes a blocking member 71 and a fourth driving source 72; the blocking member 71 is arranged in front of the second notch; the fourth driving source 72 is used to drive the blocking member 71 to move, so that the blocking member 71 blocks or removes the blockage on the inner cylinder.

[0049] During operation, the third drive source 62 drives the second pusher 61 to move forward, pushing the inner cylinder on the lifting head 31 onto the second platform 20. At this time, the fourth drive source 72 can drive the stopper 71 to block the inner cylinder. The inner cylinder is located between the second pusher 61 and the stopper 71. As the third drive source 62 drives the second pusher 61 to move forward, the inner cylinder is squeezed by the second pusher 61 and the stopper 71, causing the inner cylinder to disperse and not stick together.

[0050] It should be understood that in some cases, the inner cylinders of the inner cylinder cake can be bonded together by a binding agent. In the above structural design, the second pusher 61 and the stop 71 cooperate to squeeze the inner cylinders of the stripped cable tie, causing the inner cylinders to disperse and not stick together.

[0051] This application also provides a combined fireworks production equipment, which has a fireworks inner tube unpacking mechanism provided in the previous part.

[0052] The fireworks inner tube unpacking mechanism includes a first platform 10, a second platform 20, an upper lifting mechanism 30, a first pushing mechanism 40, and a second pushing mechanism 60. The first platform 10 has a first notch 11. The second platform 20 has a second notch 21; the second platform 20 is located above the first platform 10; the second notch 21 and the first notch 11 are aligned. The upper lifting mechanism 30 includes a lifting head 31 and a first drive source 32; the lifting head 31 is aligned with the first notch 11 and the second notch 21; the first drive source 32 can drive the lifting head 31 to move down to a first height position or up to a second height position. When the lifting head 31 is at the first height position, the first pushing mechanism 40 can push the inner cylinder cake on the first platform 10 above the lifting head 31 and align it with the second notch 21. As the lifting head 31 moves up to the second height position, the inner cylinder of the inner cylinder cake moves upward through the second notch 21 to the top of the second platform 20. The tie of the inner cylinder cake is blocked by the edge of the second notch 21, thereby separating the tie from the inner cylinder. When the lifting head 31 is at the second height position, the second pushing mechanism 60 can push the inner cylinder on the lifting head 31 onto the second platform 20.

[0053] The inner tube cake 80 is fed to the first platform 10, while only the inner tube 81 reaches the second platform 20. The inner tubes on the second platform 20 are used for subsequent loading into the fireworks launch tubes. The aforementioned fireworks inner tube unpacking mechanism can automatically separate the inner tube from the cable tie, eliminating the need for manual unpacking and feeding, thus improving the safety and efficiency of fireworks production equipment.
