[0002] The inner tube of a firework is the core component of the firework structure. It is mainly responsible for loading the pyrotechnic agent and achieving the launch, explosion and effect display when it is ignited.
[0003] During the production of fireworks, a fireworks inner tube filling device is used to load the fireworks inner tubes into the fireworks outer tubes. The fireworks inner tube filling device is equipped with a hopper for loading the fireworks inner tubes. The fireworks inner tubes in the hopper first fall onto a discharge chute below, and are then pushed out by a pushing mechanism. The pushing mechanism pushes the inner tubes from the discharge chute and further transfers them to the assembled fireworks. Therefore, each time the pushing mechanism pushes, the hopper needs to discharge the materials, and the pushing and discharge processes alternate in sequence. Currently, the inner tube discharge efficiency of the inner tube filling device needs to be improved to better meet industry needs. In addition, the hopper needs to be shaken when dropping materials, which can easily shake the materials in the inner tube out, causing safety issues. 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] The present application provides a loading and discharging assembly for firework inner tubes, which is used in the production of combination fireworks. The loading and discharging assembly includes a hopper, a conveying mechanism, and a pushing mechanism. The hopper is provided with a trough for accommodating the inner tubes, and its bottom is provided with multiple discharge openings. The conveying mechanism includes an annular transmission member, multiple transmission wheels, and a drive source. The annular transmission member is wound around the multiple transmission wheels and tensioned by the multiple transmission wheels to form a transmission structure. The drive source is used to drive the transmission wheels to rotate. The annular transmission member is located below the hopper and passes under each discharge opening in sequence. Chutes are continuously arranged around the outer circumference of the annular transmission member, each chute corresponding to a corresponding inner tube. As the annular transmission member moves, the chute on its outer circumference passes under each discharge opening in sequence to receive the inner tubes dropped from the discharge openings. The pushing mechanism is staggered in front of all discharge openings along the direction of movement of the annular transmission member and is used to push the inner tubes out of the chute.
[0032] It should be noted that in some technical solutions, a ring of chute members is arranged around the outer periphery of the annular transmission member, and the chute is arranged on the chute member. In some technical solutions, the chute can be directly and integrally formed on the annular transmission member. For example, when the annular transmission member is a transmission belt, the chute can be directly formed and arranged on the outer periphery of the transmission belt.
[0033] The pushing mechanism is staggered in front of all the dropout openings along the direction of motion of the annular transmission member and is used to push the inner cylinders out of the chutes. During operation, the annular transmission member moves, and its upper chute first passes over the dropout opening at the bottom of the trough, causing the inner cylinders in the hopper to fall into the chute on the annular transmission member. As the annular transmission member moves, the chute containing the inner cylinder moves to the position of the pushing mechanism, which then pushes the inner cylinder out of the chute. The pushing mechanism can push the inner cylinders from multiple chutes at a time, forming a row of inner cylinders. Therefore, firstly, the pushing mechanism and the material dropout opening are staggered at different positions on the annular transmission member, allowing for simultaneous material dropout and pushing. There is no need to wait for material dropout after a push, resulting in more efficient discharge. Secondly, the hopper does not need to be shaken during material dropout, which improves safety. Thirdly, as the annular transmission member moves, the chutes stir the inner tube in the hopper, thereby reducing the possibility of the inner tube getting stuck during material dropout. Fourthly, the annular transmission member drives each chute through multiple dropout openings, ensuring that each chute drops into the inner tube. The following describes the aforementioned firework inner tube loading and discharge assembly in detail with reference to the accompanying drawings.
[0034] refer to Figure 1-Figure 5The filling and discharging assembly includes a hopper 10, a conveying mechanism 20, and a pushing mechanism 30; the hopper 10 is provided with a trough 11 for accommodating an inner cylinder, and a plurality of drop openings are provided at the bottom thereof; the hopper 10 is specifically provided with a first drop opening 12 and a second drop opening 13; the conveying mechanism 20 includes an annular transmission member 21, a plurality of transmission wheels 23, and a driving source 24; the annular transmission member 21 is wound around the plurality of transmission wheels 23 and is tensioned by the plurality of transmission wheels 23 to form a transmission structure; the driving source 24 is used to drive the transmission wheels 23 to rotate; the annular transmission member 21 is wound around the plurality of transmission wheels 23 and is tensioned by the plurality of transmission wheels 23 to form a transmission structure; the driving source 24 is used to drive the transmission wheels 23 to rotate; The transmission member 21 is located below the hopper 10 and passes through the bottom of each blanking port in turn; chutes 22 are continuously arranged along the outer circumference of the annular transmission member 21, and each chute 22 corresponds to accommodating an inner cylinder; as the annular transmission member 21 moves, the chutes 22 on its outer circumference pass through the bottom position of each blanking port in turn to receive the inner cylinder falling out of the blanking port; the pushing mechanism 30 is staggered and arranged in front of all the blanking ports along the movement direction of the annular transmission member 21, and is used to push the inner cylinder in the chute 22 out.
[0035] Furthermore, a partition structure 14 is provided in the hopper 10 , and the partition structure 14 is located between the first material drop opening 12 and the second material drop opening 13 , thereby separating the material drop opening of the hopper 10 into the first material drop opening 12 and the second material drop opening 13 .
[0036] The transmission mechanism 20 is a conveyor belt mechanism. In one embodiment of the present application, the annular transmission member 21 is a transmission belt, the transmission wheel 23 is a pulley, the transmission belt is wound around multiple pulleys and tensioned by multiple transmission wheels to form a conveyor belt mechanism, and the driving source 24 can drive one of the pulleys to rotate. In a specific technical solution, the transmission mechanism 20 can be set as a synchronous belt mechanism, and the transmission belt and the pulley are both toothed structures and form an engaged transmission. Therefore, there is no relative sliding between the transmission belt and the pulley, thereby ensuring synchronous transmission and a constant transmission ratio, which is convenient for precise position control. In some embodiments, the transmission mechanism is a chain mechanism, the annular transmission member 21 is a chain, and the transmission wheel 23 is a sprocket. In addition, the driving source 24 can be set as a servo motor.
[0037] During operation, the drive source 24 drives the conveying mechanism 20 to operate, and each chute 22 passes through the first drop opening 12 and the second drop opening 13 in sequence. When the chute 22 passes through the first drop opening 12, the inner cylinder in the hopper 10 can drop and fill the chute 22 through the first drop opening 12. If the inner cylinder in the hopper 10 fails to successfully pass through the first drop opening 12 and fall into the chute 22 when the chute 22 passes through the first drop opening 12, the inner cylinder in the hopper 10 can drop and fill the chute 22 again through the second drop opening 13 to ensure that each chute 22 has an inner cylinder. As the drive source 24 drives the conveying mechanism 20 to continue operating, the chute 22 passes through the first drop opening 12 and the second drop opening 13 and reaches the position of the pushing mechanism 30. At this time, the pushing mechanism 30 can push the inner cylinder out of the chute 22.
[0038] The pushing mechanism 30 can push out the inner cylinders in multiple chutes 22 at a time, thereby pushing out a row of inner cylinders. In one embodiment of the present application, the pushing mechanism 30 includes a pushing member 31 and a first driving element 33. Among them, a plurality of pushing rods 32 are arranged on the pushing member 31; the first driving element 33 is used to drive the pushing member 31 to move, so that the plurality of pushing rods 32 respectively push the inner cylinders in the plurality of chutes 22 to the side of the annular transmission member 21. When the first driving element 33 drives the pushing member 31 to move forward, the plurality of pushing rods 32 thereon simultaneously push the inner cylinders in the plurality of chutes 22 forward. Here, the first driving element 33 can be set to various types of driving devices as needed, and can be specifically set to a cylinder.
[0039] In one embodiment of the present application, multiple discharge chutes 40 are arranged in front of the annular transmission member 21 along the pushing direction of the pushing mechanism 30. When the discharge chutes 40 are aligned with the chutes 22 on the annular transmission member 21, the pushing mechanism 30 can push the inner cylinder in the corresponding chutes 22 forward into the discharge chutes 40. Furthermore, along the pushing direction of the pushing mechanism 30, the discharge chutes 40 bend downward to guide the inner cylinder to be discharged downward.
[0040] The pushing mechanism 30 pushes the inner tube in the chute 22 forward into the discharge chute 40. Because the discharge chute 40 curves downward, as the inner tube continues to slide forward along the discharge chute 40, the discharge chute 40 guides the inner tube downward for discharge. Therefore, the firework inner tube loading and discharging assembly provided in this embodiment of the application can guide the inner tube downward for discharge by providing a curved discharge chute, eliminating the need for a tilting mechanism. This simplifies the structure and operation, and increases the reliability of the device.
[0041] refer to Figure 1-Figure 3 In one embodiment of the present application, the loading and discharging assembly further includes a push-down mechanism 50; the push-down mechanism 50 includes a push-down member 51 and a second drive element 53. The push-down member 51 is located above the discharge ends of the multiple discharge chutes 40, and is provided with multiple push-down rods 52, which correspond one to one with the multiple discharge chutes 40; the second drive element 53 is used to drive the push-down member 51 to move, so that the multiple push-down rods 52 pass downward through the discharge ends of the multiple discharge chutes 40 and enter the loading hole.
[0042] The second driving element 53 is used to drive the push-down member 51 to move, so that the multiple push-down rods 52 are respectively pushed downward through the discharge ends of the multiple discharge chutes 20 and enter the loading hole. Specifically, when the fireworks inner tubes in the discharge chute 20 are dropping, the second driving element 53 can drive the push-down member 51 to move so that the multiple push-down rods 52 are respectively pushed downward through the discharge ends of the multiple discharge chutes 20 and enter the loading hole, thereby ensuring that the fireworks inner tubes enter the loading hole and avoiding jamming. After performing a downward pressing action, the second driving element 53 can drive the push-down member 51 to move upward and return to the initial position. Here, the second driving element 53 can be set to various types of driving devices as needed, and can be specifically set to a cylinder.
[0043] The present application also provides a combined fireworks production device, comprising a loading and discharging assembly for the fireworks inner tubes provided in the aforementioned section. The loading and discharging assembly comprises a hopper, a conveying mechanism, and a pushing mechanism. The hopper is provided with a trough for accommodating the inner tubes, and a plurality of discharge openings are provided at its bottom. The conveying mechanism comprises an annular transmission member, a plurality of transmission wheels, and a driving source. The annular transmission member is wound around the plurality of transmission wheels and tensioned by the plurality of transmission wheels to form a transmission structure. The driving source is used to drive the transmission wheels to rotate. The annular transmission member is located below the hopper and sequentially passes under each discharge opening. Slide grooves are continuously arranged around the outer periphery of the annular transmission member, each corresponding to accommodating an inner tube. As the annular transmission member moves, the slide grooves on its outer periphery sequentially pass under each discharge opening to receive the inner tubes dropped from the discharge openings. The pushing mechanism is staggered in front of all discharge openings along the direction of movement of the annular transmission member, and is used to push the inner tubes out of the chutes.
[0044] In some technical solutions, the inner cylinders discharged by the filling and discharging assembly can be loaded into a transfer template, which then transfers them to the fireworks block. In some technical solutions, the inner cylinders discharged by the filling and discharging assembly can be directly loaded into the fireworks block. Therefore, the filling hole can be a hole in the transfer template or a hole in the fireworks block, depending on the actual solution.
[0045] In summary, the filling and discharging assembly of the fireworks inner tube provided in the present application has the following characteristics or processes: first, the pushing mechanism and the drop-out port are staggered at different positions of the annular transmission member, so that drop-out and pushing can be carried out simultaneously. There is no need to wait for drop-out after one push, and the discharge efficiency is higher; second, the hopper does not need to be shaken when dropping, and the safety is higher; third, as the annular transmission member moves, the chute can stir the inner tube in the hopper, thereby reducing the sticking of the inner tube when dropping; fourth, the annular transmission member will drive each chute through multiple drop-out ports to ensure that each chute falls into the inner tube.
