BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a general layout diagram of the combined fireworks effect piece filling production line of the embodiment of the present application;

[0019] Figure 2 This is another general layout diagram of the combined fireworks effect piece filling production line according to the embodiment of the present application. DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention, which will be used to further fully and clearly describe the technical solution of the present application in conjunction with the accompanying drawings.

[0021] In the combined fireworks production process, the fireworks body 1 is composed of multiple fireworks outer tubes arranged in rows and columns. The bottom of the outer tube of the fireworks body 1 is first filled with primer, and then the first layer of paper (commonly known as paper baba) is filled on the primer, and then the effect inner tube is filled on the paper, and then the second layer of paper is filled on the effect inner tube. The fireworks paper filling equipment 20 of the utility model needs to complete two paper fillings at one station. The multiple fireworks bodies 1 transmitted from the fourth conveyor line 400 are transferred to the conveyor belt of the second conveyor line 200 through the line rotation and enter the fireworks paper filling equipment 20 to complete the second layer of paper filling. 2024218185020A combined fireworks effect piece filling production line The disclosed filling production line can only realize the paper filling of a single firework body. If there are multiple fireworks bodies, the arrangement of each conveying line in the 2024218185020A combined fireworks effect piece filling production line cannot realize the transmission of multiple fireworks bodies on each conveying line.

[0022] The firework body 1 in the embodiment of the utility model is composed of three fireworks, but in actual production, it can be composed of four, five or more fireworks.

[0023] refer to Figure 1 and Figure 2, A combined fireworks effect component filling production line, including a first conveyor line 100 for conveying the fireworks body 1 to the primer filling device 10, a second conveyor line 200 for conveying the fireworks body 1 from the primer filling device 10 to the fireworks paper filling device 20, a third conveyor line 300 for conveying the fireworks body 1 from the fireworks paper filling device 20 to the inner cylinder filling device 30, and a fourth conveyor line 400 for conveying the fireworks body 1 from the inner cylinder filling device 30 to the fireworks paper filling device 20. The conveying parts of each conveyor line are conveyor belts.

[0024] Figure 1 , Figure 2 The arrows in the figure indicate the conveying direction of the fireworks body 1 on the conveyor belt. The conveying direction upward along the first conveyor line 100 is the vertical positive direction, and the opposite is the vertical negative direction; the conveying direction from left to right along the second conveyor line 200 and the third conveyor line 300 is the horizontal positive direction, and the opposite is the horizontal negative direction. The horizontal conveying direction of the fourth conveyor line 400 is from right to left. The direction of the fourth conveyor line 400 from the inner cylinder filling device 30 to the fireworks paper filling device 20 changes from the vertical upward direction to the horizontal left direction, then from the horizontal direction to the vertical downward direction, and then turns right to be collinear with the end of the second conveyor line 200.

[0025] Due to the limitation of the layout in the figure, the extended lengths of the indication arrows of the first conveyor line 100, the second conveyor line 200, the third conveyor line 300, and the fourth conveyor line 400 are only for reference indication, and the written description shall prevail. It should be noted that in the embodiments of the present invention, all directional indications (such as horizontal direction, vertical direction, parallel setting, perpendicular setting, up, down, left, right, front, back...) are only used to explain the relative position relationship and movement conditions between components in a certain specific posture (as shown in the attached drawings). If the specific posture changes, the directional indication also changes accordingly.

[0026] A primer detection device 40 is arranged between the primer filling device 10 and the fireworks paper filling device 20. The primer detection device 40 is used to detect whether the primer is filled correctly. A first pushing member 61 is arranged on one side of the primer detection device 40. The fireworks body 1 with qualified primer filling is conveyed to the fireworks paper filling device 20 along the second conveyor line 200, and the fireworks body 1 with unqualified primer filling is pushed out by the first pushing member 61 along the vertical negative direction.

[0027] A paper detection device 50 is arranged between the fireworks paper filling device 20 and the inner cylinder filling device 30. A second pushing member 62 is arranged on one side of the paper detection device 50. The fireworks body 1 with qualified paper filling is conveyed to the inner cylinder filling device 30 along the third conveyor line 300, and the fireworks body 1 with unqualified paper filling is pushed out by the second pushing member 62 along the vertical negative direction.

[0028] On one side of the firework paper filling device 20, there is a paper conveying device 68 to supply paper to the firework paper filling device 20.

[0029] Since the conveyor belts of each conveyor line are designed with different conveyor belt layouts according to different workshops, some of the conveyor belts on the conveyor lines are disconnected, and a third pusher is required to be set at each disconnection to push the firework body 1 onto the conveyor belts of each conveyor line.

[0030] In order to better save space and optimize the layout, in this embodiment, the firework body 1 has mutual conversions between the horizontal direction and the vertical direction when on the first conveyor line 100, from the first conveyor line 100 to the second conveyor line 200, from the third conveyor line 300 to the fourth conveyor line 400, and from the fourth conveyor line 400 to the second conveyor line 200. There are disconnections between the conveyor lines. To ensure the smooth conveyance of the firework body 1, in this embodiment, a third pusher 63 and a third pusher 64 are set on one side of the fourth conveyor line 400. The third pusher 63 is set on the right side in the horizontal direction of the fourth conveyor line 400 to push the firework body 1 that has completed the inner cylinder filling to the left onto the conveyor belt of the fourth conveyor line 400. The third pusher 64 is set on the upper side in the vertical direction of the fourth conveyor line 400. The third pusher 64 vertically pushes the firework body 1 on the conveyor belt of the fourth conveyor line downward, converting the conveyance direction of the firework body 1 from the horizontal conveyance direction to the vertical direction and entering the conveyor belt of the second conveyor line 200 and moving rightward into the paper filling device 20.

[0031] The first conveyor line 100 is composed of a horizontally leftward conveyor line and a vertically upward conveyor line. A third pusher 66 is provided on the vertical side where the conveyor line changes from the horizontally leftward direction to the vertically upward direction. The third pusher 66 vertically pushes the firework body 1 upward onto the vertical conveyor line of the first conveyor line 100. According to the different layouts of the workshops in practice, the first conveyor line 100 can be directly arranged as a single conveyor line and the third pusher 66 may not be required.

[0032] The primer filling device 10 is set at the junction of the first conveyor line 100 and the second conveyor line 200. Since the first conveyor line 100 and the second conveyor line 200 are perpendicular, when the conveyance direction of the firework body 1 changes from the vertically upward direction to the horizontally rightward direction, a third pusher 67 is set on the horizontal side of the primer filling device 10 to push the firework body 1 onto the conveyor belt of the second conveyor line 200.

[0033] A fourth pusher 65 and a limit member cylinder 2 are set at the discharge end of the firework paper filling device 20. The limit member cylinder 2 blocks the firework body 1 that has completed two paper fillings and is pushed by the fourth pusher 65 to the finished product table 4.

[0034] In this embodiment, all the pushing members are composed of a cylinder, with guide rods arranged on both sides of the cylinder and a pushing plate arranged at the front ends of the cylinder and the guide rods. As another implementation manner, the pushing member can be a single cylinder or other elements that can push the firework body 1 to move.

[0035] At the head or tail of each firework body conveying line, sensors that can be interlocked with each other and driving elements for driving the conveyor belt to operate are provided. The driving elements are pneumatic elements, electric elements, hydraulic elements, and specifically can be motors, cylinders, electric lead screws, etc. In this embodiment, the driving element for driving the conveyor belt to operate is a motor 5, and all the motors in the figure are labeled as 5. The start and stop of the motor 5 are controlled by the instructions of the main controller.

[0036] Since the firework body 1 completes the filling process of each station in sequence for each action, the motors arranged on each conveying line start and stop according to the control instructions through the sensors to control the operation and stop of the conveyor belt. The conveyor belts of each conveying line start and stop according to the instructions. Under the combined action of each pushing member and limiting member, the firework body 1 is conveyed to each station in the set conveying direction to complete the filling.

[0037] When the production line starts, the firework body 1 enters the conveyor belt of the first conveying line 100 from the loading table 3. The firework body 1 enters the primer filling device 10 and the primer detection device 40 in sequence under the conveying of the conveyor belt. After completing the primer filling and passing the primer filling inspection, it enters the firework paper filling device 20 along the second conveying line 200 to complete the first paper filling. After the first paper filling is completed, it enters the paper detection device 50. The firework body 1 that passes the paper filling inspection enters the inner cylinder filling device 30 along the third conveying line 300 to complete the inner cylinder filling, and then enters the fourth conveying line 400. After the line turns back, it re-enters the conveyor belt of the second conveying line 200. It enters the firework paper filling device 20 along the line of the second conveying line 200 to complete the second paper filling. The firework body 1 that completes the second paper filling is conveyed to the right along the conveyor belt of the third conveying line 300. The limiting member cylinder 2 starts to block the firework body 1 from being conveyed to the right, and the fourth pushing member 65 starts to push the firework body 1 to the finished product table 4. When the firework body 1 re-enters the conveyor belt of the second conveying line 200 after the line turns back along the fourth conveying line 400 after completing the inner cylinder filling, the motor on the first conveying line 100 or the second conveying line 200 stops operating, thereby stopping the conveyor belt from running. The firework body 1 conveyed from the first conveying line to the second conveying line 200 stops moving. After the firework body 1 that completes the second paper filling after the inner cylinder filling is pushed to the finished product table 4, the firework body 1 moves forward again to enter the firework paper filling device 20 to complete the first paper filling. At this time, the cylinder rod of the limiting member cylinder 2 retracts to allow the firework body 1 that completes the first paper filling to enter the third conveying line 300 and be conveyed to the right to enter the inner cylinder filling device.

[0038] As another implementation, a separate conveyor belt can be provided on the other side of the firework paper filling device 20 to transport the firework body 1 that has completed the second paper filling to the finished product table 4.

[0039] During the transportation of the firework body 1, the motors 5 provided on each conveyor belt will start and stop according to preset instructions to ensure that the firework bodies 1 on the production line are transported in sequence. For example, the firework body 1 transported on the first conveyor line 100 and the firework body 1 that enters the conveyor belt of the second conveyor line 200 via the fourth conveyor line 400 after the inner cylinder filling are sequentially fed into the second conveyor line 200; the firework body 1 that has completed the first paper filling and the firework body 1 that has completed the second paper filling transported on the third conveyor line 300 are transported along different routes, and so on.

[0040] To ensure production safety, the primer filling device 10, the firework paper filling device 20, and the inner cylinder filling device 30 are respectively arranged in different production rooms, and the production rooms are isolated by partition walls 67. Each conveyor line passes through the openings in the corresponding partition walls 69 to realize the transportation of the firework bodies between different production rooms. In the embodiments of the present invention, the primer filling device 10 is arranged in a separate production room, the primer detection device 40, the firework paper filling device 20, and the paper conveying device 68 are arranged in one production room, and the paper detection device 50 and the inner cylinder filling device 30 are arranged in one production room. This setting can also be changed according to the dimensions of the corresponding products and equipment and the requirements of the production line in a specific environment.

[0041] The driving device and the driving element are not limited to electric motors, hydraulic motors, pneumatic motors, etc., and the conveying members are not limited to conveyor belts, conveying plates, conveyor belts, conveying plates, etc. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0042] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
