[0028] 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, providing specific details such as specific configurations and components is only to help comprehensively understand 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 here 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.

[0029] It should be noted that, without conflict, the implementation manners in the present application and the features in the implementation manners can be combined with each other.

[0030] The embodiment of the present application provides a fireworks feeding device, which can be used for feeding the raw materials of the inner cylinder of fireworks and feeding the outer cylinder of fireworks. Referring to Figures 1 - 3 , the fireworks feeding device includes a bracket 10, a hopper 20, and a feeding assembly 30; the hopper 20 is arranged on the bracket 10; the bracket 10 is provided with a guide rail 11 on at least one side of the hopper 20. The feeding assembly 30 includes a material pouring structure 31 and a driving element 32, and materials can be placed on the material pouring structure 31; the driving element 32 is used to drive the material pouring structure 31 to move along the guide rail; the guide rail is used to guide the material pouring structure 31 to lift and turn over, so as to pour the materials into the hopper 20.

[0031] Specifically, the hopper 20 is located on the support 10, and the feeding assembly 30 is used to pour the materials into the hopper 20. Refer to Figure 2 , the driving element 32 drives the tipping structure 31 to descend along the guide rail to the bottom position, where the materials can be put into the tipping structure 31. Refer to Figure 3 , the driving element 32 drives the tipping structure 31 to ascend and flip along the guide rail. When it reaches the top position, the materials in the tipping structure 31 are poured into the hopper 20. In this way, the driving element 32 can drive the tipping structure 31 to reciprocally lift and flip, realizing automatic cyclic feeding. In addition, the fireworks feeding device can also be used in cooperation with the logistics AGV cart. The AGV cart is used to transport the materials into the tipping structure 31, thereby further improving the automation level.

[0032] In addition, it should be noted that when the fireworks feeding device is applied to the production of the inner tubes of fireworks, the raw materials included in the inner tubes can be placed in the tipping structure 31. For example, flash beads, fillers, fixing agents, oxidants, and reducing agents. When the fireworks feeding device is applied to the production of combined fireworks, military nitrate can be placed in the tipping structure 31 for filling the outer tubes.

[0033] Refer to Figure 6 , in an embodiment of the present application, the tipping structure 31 includes a tipping frame 311 and a trough 314. The tipping frame 311 includes a base 312 and a tipping hopper 313, and the tipping hopper 313 is located above the base 312. A tipping opening is provided on the tipping hopper 313; the trough 314 can be placed on the base 312 or removed from the base 312; the trough 314 is used to place materials. When the tipping frame 311 flips towards the hopper side, the materials in the trough 314 can be poured into the tipping hopper 313 and then into the hopper through the tipping opening.

[0034] Specifically, the tipping structure 31 includes a tipping frame 311 and a trough 314, and the two parts can be separated from each other. The trough 314 is used to place materials. The tipping hopper 313 is located above the base 312. When the tipping frame 311 flips towards the hopper side, the materials in the trough 314 can be poured into the tipping hopper 313 and then into the hopper through the tipping opening. As Figure 2 shown, when the tipping structure 31 is in the bottom position, the trough 314 containing materials can be placed on the base 312 of the tipping frame 311. When the tipping structure 31 reaches Figure 3When in the top position shown, the material in the chute 314 can be poured into the tipping hopper 313 and then into the hopper through the tipping opening. After one feeding operation, when the tipping structure 31 returns to the bottom position and the chute 314 is empty, an empty chute 314 can be replaced with another chute containing material. In this structural form, the tipping frame 311 and the chute 314 can be separated from each other. Therefore, multiple chutes 314 can be configured. During the feeding process, the idle chute can be replenished with material simultaneously. When the tipping frame 311 moves to the bottom position, the chute containing material can be promptly replaced with the empty chute, thereby reducing the waiting time and improving the efficiency.

[0035] In another embodiment, the chute 314 is integrated with the base 312, forming an inseparable integral structure with the base 312. Different from the Figure 6 structure shown, in this structural form, the chute 314 and the base 312 are an integral structure. When replenishing the material, the replenishment is directly carried out on the tipping structure 31 without replacing the chute.

[0036] In the embodiment of the present application, multiple guide rails parallel to each other are arranged on the bracket 10; the multiple guide rails are used to jointly guide the movement of the tipping structure 31. Refer to Figure 4 and Figure 5 , in a specific solution, two guide rails parallel to each other are arranged on the bracket 10.

[0037] Refer to Figure 2 and Figure 3 , in an embodiment of the present application, the guide rail 11 includes a first-stage guide rail 111 and a second-stage guide rail 112; the first-stage guide rail 111 is a vertical rail; the second-stage guide rail 112 is located above the first-stage guide rail 111 and bends and extends toward the hopper side.

[0038] Specifically, the first-stage guide rail 111 is a vertical rail. When the tipping structure 31 moves on the first-stage guide rail 111, the tipping structure 31 performs vertical lifting and lowering; when the tipping structure 31 moves on the second-stage guide rail 112, the tipping structure 31 flips toward the hopper 20 side. During the process of the tipping structure 31 moving from the bottom to the top, the tipping structure 31 first rises along the first-stage guide rail 111. After entering the second-stage guide rail 112, as the second-stage guide rail 112 bends and extends toward the hopper side, the tipping structure 31 flips toward the hopper 20 side, so that the material in the tipping structure 31 is poured into the hopper 20. During the process of the tipping structure 31 moving from the top to the bottom, the tipping structure 31 first passes through the second-stage guide rail 112, flips away from the hopper side, and after entering the first-stage guide rail 111, vertically descends to the bottom position.

[0039] Refer to Figure 4 and Figure 5, in an embodiment of the present application, a guide groove 113 is arranged along the extending direction of the guide rail 11; a plurality of rotatable rollers are connected to the blanking structure 31, and the plurality of rollers are distributed at multiple positions along the extending direction of the guide groove 113; the plurality of rollers are placed in the guide groove 113 and are restricted to move along the guide groove 113.

[0040] Specifically, a plurality of rollers are connected to the blanking structure 31, and the rollers are arranged in the guide groove 113 of the guide rail 11. Under the restriction of the guide groove 113, the rollers can only move along the direction defined by the guide groove 113. Further, when there are multiple guide rails 11, a plurality of rollers are arranged in the guide groove 113 of each guide rail 11. In Figure 4 and Figure 6 In the structure shown, the two guide rails 11 jointly guide the blanking structure 31 to move, and a plurality of rollers connected to the blanking structure 31 are arranged in both of the two guide rails 11.

[0041] Refer to Figure 4 and Figure 5 , in an embodiment of the present application, a first roller bracket 315 and a second roller bracket 318 are provided on the blanking structure 31; the first roller bracket 315 is located above the second roller bracket 318. The first roller bracket 315 includes a first roller seat 316 and a first roller 317. The first roller 317 is installed on the first roller seat 316, and the first roller 317 corresponds to the guide rail one by one. The second roller bracket 318 includes a second roller seat 319 and a second roller 310. The second roller 310 is installed on the second roller seat 319; the second roller 310 corresponds to the guide rail one by one, and for any one guide rail, there are multiple second rollers and they are distributed at multiple positions along the extending direction of the guide groove 113. Among them, the first roller seat 316 is fixedly connected to the blanking structure 31, and the second roller seat 319 is movably connected to the blanking structure 31. Further, the second roller seat 319 is hinged to the blanking structure 31. When the first roller 317 enters the second-section guide rail 112, due to the movable connection between the second roller seat 319 and the blanking structure 31, as the second-section guide rail 112 bends and extends towards the hopper side, the blanking structure 31 can rotate relative to the second roller seat 319, thereby realizing flipping.

[0042] Refer to Figure 2 , and Figure 4 and Figure 5, in an embodiment of the present application, the driving element 32 drives the tipping structure 31 to move through a chain mechanism. Further, the chain mechanism includes a chain 323 and a sprocket assembly, and the sprocket assembly is composed of a sprocket shaft 321 and a sprocket 322 mounted on the sprocket shaft 321. The chain is of an open structure, one end of which is connected to the bracket 10, and the other end is connected to the second roller seat 319 or the tipping structure 31. The sprocket is rotatably mounted on the sprocket shaft 321, and the sprocket abuts upward against the chain 323 and meshes therewith; the driving element 32 can drive the sprocket shaft 321 to move up and down, so that the chain 323 pulls the tipping structure 31 to act.

[0043] In Figure 2 In the structure shown, the driving element 32 is a cylinder. Since one end of the chain 323 is connected to the bracket 10, when the driving element 32 drives the sprocket shaft 321 to move upward, the sprocket shaft 321 abuts against the chain 323 and moves upward, and the other end of the chain 323 pulls the second roller seat 319 to move upward, so as to drive the tipping structure 31 to move upward and turn. Conversely, when the driving element 32 drives the sprocket shaft 321 to move downward, the tipping structure 31 will move in the reverse direction to the bottom.

[0044] The present application also provides a production line, which includes: the above-mentioned fireworks feeding device. When the production line is used to produce the inner cylinders of fireworks, the fireworks feeding device is applied to the feeding of the raw materials for the inner cylinders of fireworks, and the raw materials contained in the inner cylinders, such as bright beads, fillers, solid primers, oxidants, and reducing agents, can be placed in the tipping structure 31. When the production line is used to produce combined fireworks, the fireworks feeding device is applied to the feeding of military nitrate for the outer cylinders of combined fireworks, and military nitrate can be placed in the tipping structure 31 to fill the outer cylinders.

[0045] In the fireworks feeding device provided in the embodiment of the present application, the driving element drives the tipping structure to move along the guide rail, so that under the guidance of the guide rail, the tipping structure rises and turns, so as to pour the material into the hopper. Therefore, the present application provides a fireworks feeding device for automatic feeding, which can improve the automation level of fireworks production equipment.
