[0030] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.
[0031] The embodiment of this application provides a fireworks raw material conveying device, which is applied to the conveying of fireworks raw materials in the fireworks production process.

In this application, the driving source can be a motor.
[0033] Figure 4 A schematic diagram of the container 30 is shown. The container 30 has a receiving cavity 31 for receiving materials and an opening 32. In Figure 1 the structure shown, an explosion-proof wall W is provided between the first tensioning wheel 21 and the second tensioning wheel 22, and the conveyor 23 passes through the explosion-proof wall W and cooperates with the first tensioning wheel 21 and the second tensioning wheel 22 at both ends respectively.
[0034] When the container 30 is in the a position, the container 30 is located on the first side of the explosion-proof wall W. First, the container 30 stays at the a position for feeding. After the feeding is completed, the driving source drives the first tensioning wheel 21 and / or the second tensioning wheel 22 to rotate to drive the conveying member to move. The container 30 moves with the conveying member 23 and passes through the explosion-proof wall W into the b position on the second side of the explosion-proof wall W. Then, the driving source continues to drive the conveying member 23 to move, and the container 30 enters the c position outside the second tensioning wheel 22. At this time, the conveying member 23 is wound around the second tensioning wheel 22 and bends and turns along the circumferential direction of the second tensioning wheel 22; the container 30 in the c position is tilted, and the raw materials in the accommodating cavity 31 are poured out from the opening 32 into the hopper below, realizing inclined pouring; after the container 30 performs inclined pouring in the c position, the driving source continues to drive the conveying member 23 to move to the d position. Finally, the container 30 continues to move with the conveying member 23 and returns to the a position after passing through the explosion-proof wall W and the first tensioning wheel 21. Through the above process, the fireworks raw material conveying device realizes the conveyance of fireworks raw materials once. In the embodiment of the present application, a plurality of containers 30 can be arranged at intervals on the conveying member 23, and the plurality of containers 30 can all be used for the conveyance of fireworks raw materials, which can improve the conveyance efficiency. From the working process of the above-mentioned fireworks raw material conveying device, it can be seen that the container can be loaded with the required amount of materials as needed, can be accurately conveyed with an accurate conveying amount, and only performs material dropping and material receiving during the conveying process, and will not squeeze the materials during conveying, which is safer.
[0035] It should be noted that the container 30 is fixedly connected to the conveying member 23, and the opening 32 thereon remains facing the outside of the closed loop of the conveying member 23. When the container 30 passes through the second tensioning wheel 22, the container 30 will turn over, and the materials in the container 30 will be poured out through the opening 32. In Figure 1 the structure shown, the first tensioning wheel 21 and the second tensioning wheel 22 rotate clockwise, the upper part of the conveying member 23 moves from left to right, and the lower part of the conveying member 23 moves from right to left.
[0036] Reference Figure 2 In one embodiment of the present application, the fireworks raw material conveying device has two conveying units 20 arranged at intervals horizontally, and each conveying unit 20 is assembled by a first tensioning wheel 21, a second tensioning wheel 22, and a conveying member 23; the first tensioning wheels 21 of the two conveying units 20 are coaxially arranged, and the second tensioning wheels 22 of the two conveying units 20 are coaxially arranged; the conveying members 23 of the two conveying units 20 are both connected to the container 30.
[0037] In Figure 2In the structure shown, the two conveying units 20 are arranged side by side, and the container 30 is bridged on the conveying members 23 on both sides. The first tension wheels 21 of the two conveying units 20 are coaxially installed and are all installed on the first rotating shaft; the second tension wheels 22 of the two conveying units 20 are coaxially installed and are all installed on the second rotating shaft; in a specific technical solution, the first rotating shaft is equipped with a driving source, and the two first tension wheels 21 serve as driving wheels. In another specific technical solution, the second rotating shaft is equipped with a driving source, and the two second tension wheels 22 serve as driving wheels.
[0038] Continue to refer to Figure 2 , in an embodiment of the present application, the frame 10 is provided with a support guide 11, and the support guide 11 can support and guide the movement of the conveying member 23. The container 30 is fixedly connected to the conveying member 23 and applies a gravity load to the conveying member 23, and the support guide 11 can bear the load from the container 30. Further refer to Figure 3 , the support guide 11 is provided with a guide groove 12, and the conveying member 23 is inserted into the guide groove 12, and the guide groove 12 can limit the deformation of the conveying member 23. Further, the support guide 11 is arranged between the first tension wheel 21 and the second tension wheel 22, its first end extends to a position close to the first tension wheel 21, and its second end extends to a position close to the second tension wheel 22.
[0039] In an embodiment of the present application, the conveying member 23 is a chain, and the first tension wheel 21 and the second tension wheel 22 are sprockets adapted to the chain. Here, the transmission mechanism composed of the first tension wheel 21, the second tension wheel 22, and the conveying member 23 is a chain mechanism, which transmits power and motion through the meshing of the chain and the sprocket, with a simple and reliable structure and no slipping phenomenon. In Figure 2 and Figure 3 In the structure shown, the conveying member 23 and the first tension wheel 21, the second tension wheel 22 form a chain mechanism.
[0040] In an embodiment of the present application, the conveying member 23 is a belt, and the first tension wheel 21 and the second tension wheel 22 are belt wheels adapted to the belt. Here, the transmission mechanism composed of the first tension wheel 21, the second tension wheel 22, and the conveying member 23 is a belt transmission mechanism, which transmits power and motion through the interaction between the belt and the belt wheel. In a technical solution, the belt is a toothed synchronous belt, which meshes with the toothed belt wheel for transmission, and there is no relative sliding between the belt and the belt wheel.
[0041] Refer to Figure 1 , the embodiment of the present application also provides a fireworks raw material feeding device, which includes: the fireworks raw material conveying device provided in the previous part, and a blanking assembly 40. Refer to Figure 5, the blanking assembly 40 includes a first-stage hopper 41, a plurality of second-stage hoppers 42, and a third-stage hopper 43; wherein, the first-stage hopper 41 is located above the plurality of second-stage hoppers 42, and the blanking holes at its bottom can blank material simultaneously into the plurality of second-stage hoppers 42; the plurality of second-stage hoppers 42 are located above the third-stage hopper 43, and the blanking holes of each second-stage hopper can blank material into the third-stage hopper 43; the conveyor 23 can guide the container 30 to reach below the third-stage hopper 43 to receive the blanking from the third-stage hopper 43; the blanking holes of the first-stage hopper 41 are equipped with a first valve mechanism 44a capable of controlling the opening or closing of the blanking holes; the blanking holes of the plurality of second-stage hoppers 42 are correspondingly equipped with second valve mechanisms capable of controlling the opening or closing of the blanking holes.
[0042] During feeding, the fireworks raw materials first enter the first-stage hopper 41. When the first valve mechanism 44a at the bottom of the first-stage hopper 41 is opened, the fireworks raw materials in the first-stage hopper 41 blank material simultaneously through the blanking holes at the bottom into the plurality of second-stage hoppers 42 below, and the materials in the first-stage hopper 41 are roughly evenly blanked into the plurality of second-stage hoppers 42. When the conveyor 23 drives the container 30 to reach below the third-stage hopper 43, the fireworks raw materials in the second-stage hopper 42 can fall into the container 30 through the third-stage hopper 43. The blanking holes of the plurality of second-stage hoppers 42 are correspondingly equipped with second valve mechanisms. Therefore, the plurality of second-stage hoppers 42 can blank material one by one. Each time, one second-stage hopper 42 can be used to blank material into the container 30; when a container to be blanked enters below the third-stage hopper 43, the second valve mechanism of one of the second-stage hoppers 42 can be opened, and the fireworks raw materials in this second-stage hopper are all blanked into the container through the third-stage hopper 43. After all the fireworks raw materials in all the second-stage hoppers 42 are blanked, the first valve mechanism 44a of the first-stage hopper 41 is opened to replenish the blanking into the plurality of second-stage hoppers 42 simultaneously.
[0043] The plurality of second-stage hoppers 42 are used for distributing the materials of the first-stage hopper 41 and controlling the amount of material blanked into the container each time. After distribution, the amount of material in each second-stage hopper corresponds to the amount of material blanked into the container once. Therefore, each time when blanking into the container, only the second valve mechanism of one of the second-stage hoppers needs to be opened. In Figure 5 the structure shown, the blanking assembly 40 includes four second-stage hoppers 42.
[0044] The first valve mechanism and the second valve mechanism have various possible implementation manners. Refer to Figure 6 , in a specific embodiment, the first valve mechanism 44a includes a driving element 441 and an openable and closable door panel 442. The driving element drives the door panel to act to open or close the blanking holes at the bottom of the first-stage hopper 41. The second valve mechanism is similar to the first valve mechanism and will not be repeated here.
[0045] The embodiment of the present application also provides an inner cylinder production line, which includes the fireworks raw material conveying device provided in the previous part. The fireworks raw material conveying device can be used to convey the raw materials of the inner cylinder, such as flash beads, gunpowder, fillers, and solid primers, etc. For relevant descriptions, refer to the description of the fireworks raw material conveying device in the previous part, which will not be elaborated here.

The fireworks raw material conveying device can be used to convey raw materials such as military nitrate. For relevant descriptions, refer to the description of the fireworks raw material conveying device in the previous part, which will not be elaborated here.

The fireworks raw material conveying device includes a frame, a first tensioning wheel, a second tensioning wheel, a conveyor, a driving source, and a container; the conveyor is in a closed loop shape and is tensioned by the first tensioning wheel and the second tensioning wheel at both ends. A container is fixed on the conveyor. When the driving source drives the first tensioning wheel and / or the second tensioning wheel to rotate, the container moves accordingly to convey the fireworks raw materials. When the container passes through the position of the tensioning wheel, the container will tilt, so that the raw materials in the accommodating cavity pour out from the opening, realizing inclined pouring. On the one hand, compared with the pipeline conveying device, such as a screw conveying mechanism, the fireworks raw material conveying device provided by the present application can completely output all the fireworks raw materials. On the second hand, the fireworks raw material conveying device provided by the present application can perform precise conveying with a precise conveying amount.
