Description

Technical Field

[0001] The present application relates to the technical field of fireworks production equipment, and in particular to a combined fireworks filling production line. Background Art

[0002] Combination fireworks are composed of multiple single-tube fireworks. Currently, combination fireworks can be produced using automated production lines. Multiple production and filling equipment need to be arranged on the fireworks production line, such as military gunpowder filling equipment, paper babar filling equipment, and inner tube filling equipment.

[0003] During production, multiple filling machines on the production line load fireworks bodies multiple times. The military saltpeter filling machine is used to load the fireworks bodies with military saltpeter, the paper bar filling machine is used to load the fireworks bodies with paper bar, and the inner tube filling machine is used to load the fireworks bodies with inner tubes. Consequently, existing production lines contain multiple filling machines, each of which independently positions and loads the fireworks bodies. The fireworks bodies are transferred between the filling machines using conveyors or manual handling. This results in a loose production line structure, resulting in large space requirements, low efficiency, and a high labor demand. Utility Model Content

DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present application and, in conjunction with the accompanying drawings, further description of the technical solutions of the present application is provided, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided solely to assist in a comprehensive understanding of the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, for clarity and brevity, descriptions of known functions and configurations have been omitted.

[0030] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0031] Combination fireworks are composed of multiple single-tube fireworks. Production requires multiple loading processes, including military-grade saltpeter loading, paper-bagging loading, and inner-tube loading. Accordingly, multiple production and loading equipment are deployed on the production line for automated loading. The military-grade saltpeter loading equipment is used to load the fireworks with military-grade saltpeter, the paper-bagging loading equipment is used to load the fireworks with paper-bagging, and the inner-tube loading equipment is used to load the fireworks with inner-tubes. However, in existing combination fireworks production, each loading equipment independently positions and loads the fireworks. The fireworks are transferred between the loading equipment using conveying mechanisms or manual handling. This results in a loose production line structure, resulting in large space requirements, low efficiency, and a high labor requirement. To address this issue, the present application provides a combination fireworks loading production line, which will be described in detail below with reference to the accompanying drawings.

[0032] The present invention provides a combined fireworks filling production line comprising a frame, a conveyor, and multiple filling devices. The conveyor can operate along a predetermined conveying direction to transport fireworks. Multiple filling devices are sequentially arranged at different positions along the conveyor's conveying direction, enabling simultaneous loading of fireworks at different positions on the conveyor. During production, the conveyor sequentially transports fireworks. When fireworks on the conveyor reach a loading position, the multiple filling devices can simultaneously load them. Specifically, the filling devices include a military-grade saltpeter filling device, an inner tube filling device, and a paper bar filling device. The military-grade saltpeter filling device is used to load military-grade saltpeter into fireworks; the inner tube filling device is used to load inner tubes into fireworks; and the paper bar filling device is used to load paper bar into fireworks.

[0033] On the one hand, by sequentially arranging multiple loading devices at different positions on a single conveyor, the aforementioned combined fireworks loading production line is more compact, reducing space usage, improving production efficiency, and reducing manpower. On the other hand, the conveyor can simultaneously position and load all fireworks on it, reducing the number of positioning operations and the number of positioning mechanisms.

[0034] refer to Figure 1 In one embodiment of the present application, a combined fireworks filling production line includes a frame 10, a conveyor 20, and multiple filling devices 30; the conveyor 20 runs along a set conveying direction x to convey fireworks, and the multiple filling devices 30 are sequentially arranged at different positions along the conveying direction x of the conveyor 20. The multiple filling devices 30 can simultaneously fill fireworks at different positions on the conveyor 20.

[0035] Furthermore, the combined fireworks filling production line also has a feeding conveyor device 40, which is arranged at the feeding end of the conveyor 20; the feeding conveyor device 40 is used to convey the fireworks bodies to the feeding end of the conveyor 20. In a specific embodiment, the feeding conveyor device 40 is a belt conveyor mechanism, which sequentially conveys the fireworks bodies W to the feeding end of the conveyor 20. Figure 1 In the structure shown, the fireworks bodies W on the loading and conveying device 40 can be pushed one by one onto the conveyor 20 by the pushing mechanism.

[0036] Further references Figure 2 The filling equipment 30 includes military saltpeter filling equipment, inner tube filling equipment, and paper bar filling equipment; the military saltpeter filling equipment 31 is used to fill military saltpeter into the fireworks body; the inner tube filling equipment 32 is used to fill the inner tube into the fireworks body; the paper bar filling equipment 33 is used to fill the paper bar into the fireworks body. Figure 2 In the structure shown, military gunpowder filling equipment 31, paper bar filling equipment 33, inner tube filling equipment 32, and paper bar filling equipment 33 are arranged in sequence along the conveying direction x of the conveyor 20, and the fireworks body is sequentially filled with military gunpowder, filled with paper bar for the first time, filled with inner tube, and filled with paper bar for the second time.

[0037] refer to Figure 3 and Figure 4 In one embodiment of the present application, the conveyor 20 is provided with a plurality of positioning members 25 evenly spaced along its conveying direction x. Each positioning member 25 defines the position of a pyrotechnic body. The plurality of positioning members 25 can sequentially define the pyrotechnic bodies on the conveyor 20 at even intervals along the conveying direction. The plurality of loading devices 30 can simultaneously achieve loading alignment with pyrotechnic bodies at different positions on the conveyor 20.

[0038] Specifically, the positioning members 25 are rod-shaped and spaced apart on the conveyor 20. During operation, each positioning member 25 can push a corresponding pyrotechnic object. During pushing, the positioning member 25 abuts against the pyrotechnic object, thereby defining the position of the pyrotechnic object. Because the positioning members 25 are evenly spaced along the conveying direction x, the pyrotechnic objects defined by each positioning member 25 are also evenly spaced along the conveying direction x. Furthermore, multiple loading devices 30 simultaneously align with pyrotechnic objects at different positions on the conveyor 20. After each alignment, the multiple loading devices simultaneously load the pyrotechnic objects at different positions on the conveyor 20. Furthermore, because the pyrotechnic objects are evenly spaced along the conveying direction x, the multiple loading devices 30 consistently maintain simultaneous loading alignment with the pyrotechnic objects at different positions on the conveyor 20 as the conveyor 20 operates.

[0039] In one embodiment of the present application, the filling mechanism on each filling device is aligned with a row of fireworks outer tubes on the fireworks body for filling; as the conveyor 20 moves to different filling positions in sequence, the multiple filling devices 30 fill the fireworks body row by row.

[0040] Specifically, the firework body has multiple rows of firework outer tubes, and the loading equipment loads one row of firework outer tubes at a time. Each time the conveyor 20 moves forward to a loading position, each loading equipment performs a loading operation, loading a row of firework outer tubes on the firework body. In one embodiment, the firework body is provided with seven rows of firework outer tubes, and the loading equipment needs to load one firework body seven times.

[0041] In one embodiment of the present application, the conveyor 20 is driven by a servo motor; the servo motor is controlled by a control device to sequentially move the conveyor 20 to different loading positions. The servo motor enables precise control of the conveyor 20, allowing the conveyor 20 to accurately move to different loading positions.

[0042] In one embodiment of the present application, the combined fireworks loading production line further includes a position sensor connected to a control device via a data cable. The position sensor is used to sense each positioning element 25, enabling the control device to control the conveyor 20 to sequentially move to different loading positions for row-by-row loading based on the position sensor's sensed position of the positioning element 25. The position sensor can be configured as a variety of sensors as needed. In one specific embodiment, the position sensor can be a slot-type photoelectric sensor.

[0043] Specifically, a firework body has N rows of outer tubes. To complete the loading of one firework body, the loading equipment needs to perform N positioning and loading operations. When the position sensor detects a positioning member 25, the control device resets the distance to zero and uses this position as a reference to control the conveyor 20 to move to different loading positions to load each row. Each positioning member 25 corresponds to the displacement of a firework body. After each firework body is loaded, before the next firework body is loaded, the position sensor senses the position of the positioning member 25 and calibrates it. This prevents error accumulation and allows the production line to operate continuously without excessive positioning errors.

[0044] refer to Figure 3-5 In one embodiment of the present application, the conveyor 20 is a chain mechanism, and a plurality of positioning members 25 are evenly spaced and arranged on the chain of the chain mechanism; as the chain mechanism runs, the corresponding positioning members 25 push the corresponding fireworks body to move. Figure 3 and Figure 4In the structure shown, the positioning member 25 is a rod-shaped body, which is distributed on the chain of the chain mechanism. When the chain mechanism is running, the chain operation drives all the positioning members thereon to move synchronously.

[0045] The chain mechanism 20 further comprises two spaced-apart, parallel chains 21, multiple pairs of sprockets, and a drive source 23. Positioning members 25 are horizontally connected to the two chains 21, and multiple pairs of sprockets are arranged at various locations on the chains 21 to collectively tension the chains 21. The two sprockets 22 in each pair of sprockets mesh with the two chains 21, respectively. The drive source 23 is dynactuated with at least one pair of sprockets to drive the synchronous rotation of the pair. The drive source 23 is a servo motor, which precisely drives the sprockets and chains, thereby precisely controlling the displacement of the fireworks.

[0046] The frame 10 is equipped with a conveying platform 11, on which the fireworks are slidably transported. The conveying platform 11 extends along the conveying direction of the chain mechanism and sequentially passes through the loading positions of multiple loading devices. Positioning brackets 12 are located on either side of the conveying platform 11 along the conveying direction. These brackets 12 limit the lateral position of the fireworks. The conveying platform 11 supports the fireworks, allowing them to slide forward on the conveying platform 11. The positioning brackets 12 on either side of the conveying platform 11 provide lateral positioning for the fireworks, allowing them to be loaded directly into the various loading devices, with the forward and backward position of the fireworks controlled by the conveyor 20.

[0047] Therefore, in the embodiments of the present application, a combined fireworks filling production line includes a frame, a conveyor, and multiple filling devices. The conveyor can operate along a predetermined conveying direction to transport fireworks bodies, and multiple filling devices are sequentially arranged at different positions along the conveyor's conveying direction. The multiple filling devices can simultaneously load fireworks bodies at different positions on the conveyor. On the one hand, by sequentially arranging multiple filling devices at different positions on a single conveyor, the combined fireworks filling production line is more compact, reducing space usage, improving production efficiency, and reducing manpower. On the other hand, all fireworks bodies on the conveyor can be positioned and loaded simultaneously, reducing the number of positioning operations and the number of positioning mechanisms.
