Description

Technical Field

[0001] This application relates to the field of fireworks production equipment technology, and in particular to an inner cylinder discharge component and a fireworks production line. Background Technology

[0002] The inner tube of a firework is the core component of its structure, primarily responsible for carrying the pyrotechnic agents and enabling them to ascend, explode, and create visual effects during ignition. The inner tube typically consists of a tube body, a sealing layer, effect powder (such as bright beads or detonating explosives), and a fuse. The two ends of the tube are sealed with soil or a priming agent, and the inside is filled with detonating explosives and effect powders. The propellant propels the firework into the air, where it explodes to create the spectacular effect.

[0003] In current inner cylinder filling equipment, material is dropped from a hopper onto a downward track, and a pushing mechanism continuously pushes the inner cylinder forward on the track. For example, the inner cylinder filling equipment for molded fireworks disclosed in Chinese Patent CN201910769024.6 includes a pusher, which comprises several push rods corresponding to the inner cylinder positioning slots. The push rods are connected to a drive cylinder that moves back and forth linearly, pushing the inner cylinder of the fireworks, which has been dropped from the hopper into the inner cylinder positioning slot, forward.

[0004] In existing inner cylinder filling equipment, when the inner cylinder is discharged, it falls onto the track and is placed horizontally along the track. The pushing mechanism needs to abut against the end of the inner cylinder to push it forward, which can easily damage the inner cylinder. Utility Model Content

[0005] The technical problem to be solved by this application is to provide an inner cylinder discharge component and a fireworks production line, addressing the aforementioned shortcomings of the prior art.

[0006] An inner cylinder discharge assembly includes:

[0007] The hopper is equipped with a trough, and a material discharge channel is provided at the bottom of the trough;

[0008] A base is arranged below the hopper; the base is provided with a discharge slide suitable for the inner cylinder to slide; the discharge slide has a feeding section, a discharge section, and a turning section; the feeding section is configured as a horizontal slide suitable for the inner cylinder to slide in a horizontal state; the discharge section is configured as a vertical slide suitable for the inner cylinder to slide in a vertical state; the turning section is located between the feeding section and the discharge section, smoothly turning and extending from the horizontal slide of the feeding section to transition to the vertical slide of the discharge section, so that the inner cylinder changes from a horizontal state to a vertical state after passing through the turning section; the feeding section is located below the discharge channel and can receive the inner cylinder falling from the discharge channel;

[0009] The pushing mechanism includes a pushing component and a first driving device; the first driving device is used to drive the pushing component to push the inner cylinder of the feeding section to the discharge section laterally, so that the discharge slide outputs the inner cylinder.

[0010] Optionally, the inner cylinder discharge assembly has multiple hoppers, and the discharge channels of the multiple hoppers can all feed material into the feed section of the discharge chute.

[0011] Optionally, the inner cylinder discharge assembly further includes a rotary wheel mechanism; the rotary wheel mechanism includes:

[0012] A rotating body has a discharge cavity between the discharge channel and the trough, and the rotating body is housed in the discharge cavity; a plurality of receiving slots for accommodating the inner cylinder are evenly arranged along the outer periphery of the rotating body.

[0013] The second driving device is used to drive the rotating body to rotate, so that the inner cylinders in the material trough fall one by one into the receiving groove on the upper side of the rotating body, and fall one by one into the material dropping channel when the receiving groove rotates to the position of the material dropping channel.

[0014] Optionally, the second driving device is a ratchet mechanism; the ratchet mechanism includes a ratchet, a pawl, and a driving element; the ratchet is coaxially connected to the rotating body to achieve coaxial rotation; the driving element reciprocates to drive the pawl to move so that the ratchet and the rotating body rotate synchronously by a set angle α each time; and, for each set angle α that the rotating body rotates, the receiving slot on it rotates forward to the position of the next adjacent receiving slot.

[0015] Optionally, the second driving device is a motor, which can drive the rotating body to rotate synchronously by a set angle α each time; and, each time the rotating body rotates by a set angle α, the receiving slot on it rotates forward to the position of the next adjacent receiving slot.

[0016] Optionally, the base is equipped with a cover to cover the turning section of the discharge chute.

[0017] Optionally, a baffle block and an elastic element acting on the baffle block are installed in the discharge section of the discharge chute; when the first driving device drives the inner cylinder in the discharge chute to move forward, the inner cylinder in the discharge chute can overcome the elastic force and push the baffle block away.

[0018] Optionally, the front end of the pusher is configured as a V-shaped groove; the V-shaped groove is adapted to the outer peripheral surface of the inner cylinder so that the inner cylinder can be stuck in the V-shaped groove when the pusher pushes the inner cylinder of the feeding section forward and laterally.

[0019] This application also provides a fireworks production line, which includes the aforementioned inner cylinder discharge assembly.

[0020] Optionally, the fireworks production line is equipped with multiple inner cylinder discharge components.

[0021] In this application, driven by the first driving device, the pusher can push the inner cylinder out of the discharge chute laterally, so that the inner cylinder passes through the feeding section, the turning section, and the discharge section in sequence. Since the turning section is located between the feeding section and the discharge section and smoothly extends from the transverse chute of the feeding section to the longitudinal chute of the discharge section, the inner cylinder changes from a horizontal state to a vertical state after passing through the turning section. Therefore, the inner cylinder discharge assembly provided in this application has the following characteristics: the inner cylinder is discharged in a vertical state along the discharge chute; when the pusher pushes the inner cylinder, it abuts against the side of the inner cylinder, which is less likely to damage the inner cylinder and provides higher safety.

Detailed Implementation

[0028] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0030] This application provides an inner cylinder discharge assembly for use in a fireworks production line. The inner cylinder discharge assembly continuously pushes out the inner cylinder from the hopper for filling. (Reference) Figure 1 and Figure 2 The inner cylinder discharge assembly includes a hopper 10, a base 20, and a pushing mechanism 30.

[0031] The hopper 10 is provided with a trough 11, and a discharge channel 12 is provided at the bottom of the trough 11. The base 20 is arranged below the hopper 10; the base 20 is provided with a discharge slide 21 suitable for the inner cylinder W to slide; the discharge slide 21 has a feeding section 211, a discharge section 212, and a turning section 213; the feeding section 211 is set as a horizontal slide suitable for the inner cylinder W to slide in a horizontal state; the discharge section 212 is set as a vertical slide suitable for the inner cylinder W to slide in a vertical state; the turning section 213 is located between the feeding section 211 and the discharge section 212, and smoothly turns and extends from the horizontal slide of the feeding section 211 to transition to the vertical slide of the discharge section 212, so that the inner cylinder W changes from a horizontal state to a vertical state after passing through the turning section 213; the feeding section 211 is located below the discharge channel 12 and can receive the inner cylinder W falling from the discharge channel 12. The pushing mechanism 30 includes a pushing component 31 and a first driving device 32. The first driving device 32 is used to drive the pushing component 31 to push the inner cylinder W of the feeding section 211 to the discharge section 212, so that the discharge chute 21 outputs the inner cylinder W.

[0032] The material trough 11 can be used to hold the inner cylinder, which can then be dropped downwards through the material discharge channel 12. When the inner cylinder falls into the feeding section 211 of the discharge chute 21, the first drive device 32 drives the pusher 31 to push the inner cylinder W in the feeding section 211 laterally towards the discharge section 212. The inner cylinder W in the feeding section 211 needs to pass through the turning section 213 to reach the discharge section 212. When the inner cylinder passes through the turning section 213, it changes from a horizontal state to an upright state and is output in an upright state at the discharge section 212. In addition, the first drive device 32 can be configured as various types of drive devices as needed, such as cylinders, electric cylinders, etc. Further, as the discharge section 212 outputs the upright inner cylinder, the inner cylinder is pushed laterally into the mold in sequence for further filling into the fireworks tube. In the above-mentioned discharge process of the inner cylinder, the pusher pushes the inner cylinder against the side of the inner cylinder, which is less likely to damage the inner cylinder and is safer.

[0033] In one embodiment of this application, reference is also made to Figure 3The inner cylinder discharge assembly also includes a rotating wheel mechanism 40; the rotating wheel mechanism 40 includes a rotating body 41 and a second driving device 42. A discharge cavity 13 is provided between the discharge channel 12 and the trough 11, and the rotating body 41 is accommodated in the discharge cavity 13; a plurality of receiving slots 411 for accommodating the inner cylinders are evenly arranged along the outer periphery of the rotating body 41. The second driving device 42 is used to drive the rotating body 41 to rotate, so that the inner cylinders in the trough 11 fall one by one into the receiving slots 411 on the upper side of the rotating body 41, and fall one by one into the discharge channel 12 when the receiving slots 411 rotate to the position of the discharge channel 12.

[0034] When the rotating body 41 rotates in the material discharge chamber 13, it agitates the inner cylinder in the material trough 11, allowing the inner cylinder to fall into the receiving trough 411. As the rotating body 41 rotates, the receiving troughs 411 on the outer periphery of the rotating body 41 move one by one to a position facing the material trough 11, receiving the inner cylinder falling into the material trough 11 in sequence; at the same time, the receiving troughs 411 on the outer periphery of the rotating body 41 move one by one to the position of the material discharge channel 12, releasing the inner cylinder into the material discharge channel 12 in sequence. Furthermore, for each predetermined angle α that the rotating body 41 rotates, the receiving slots 411 on it rotate forward to the position of the next adjacent receiving slot 411. An empty receiving slot 411 on the rotating body 41 moves to a position facing the material trough 11, where the material trough 11 discharges material, filling the inner cylinder into the receiving slot 411. Simultaneously, a receiving slot 411 on the rotating body 41 containing an inner cylinder moves to a position facing the discharge channel 12, where an inner cylinder is released into the discharge channel 12. Therefore, for each predetermined angle α that the rotating body 41 rotates, the material trough 11 discharges material onto the rotating body 41, and simultaneously, the rotating body 41 discharges material into the discharge channel 12, allowing the inner cylinders in the material trough 11 to fall one by one into the discharge channel 12. For each inner cylinder that falls into the discharge channel 12, the pushing mechanism 30 pushes it forward, causing the discharge chute 21 to output the inner cylinders one by one.

[0035] In one embodiment of this application, reference is also made to Figure 3The second driving device 42 is a ratchet mechanism; the ratchet mechanism 421 includes a ratchet 421, a pawl 422, and a driving element 423; the ratchet 421 is coaxially connected to the rotating body 41 to achieve coaxial rotation; the driving element 423 reciprocates to drive the pawl 422 to rotate synchronously by a set angle α each time; and, for each set angle α rotation of the rotating body 41, the receiving groove 411 on it rotates forward to the position of the next adjacent receiving groove 411. The ratchet mechanism is a unidirectional intermittent motion mechanism composed of a ratchet and a pawl. Each time the driving element 423 extends or retracts, the pawl 422 actuates the ratchet 421 once, causing the ratchet 421 and the rotating body 41 to rotate by a set angle α. For more information on the ratchet mechanism, please refer to the prior art, which will not be elaborated here. Furthermore, for each predetermined angle α that the rotating body 41 rotates, the receiving slot 411 on it rotates forward to the position of the next adjacent receiving slot 411. An empty receiving slot 411 on the rotating body 41 moves to a position facing the material trough 11, where the material trough 11 discharges material, and the inner cylinder is filled into the receiving slot 411. Simultaneously, a receiving slot 411 on the rotating body 41 containing the inner cylinder moves to a position facing the material discharge channel 12, and this receiving slot 411 releases an inner cylinder into the material discharge channel 12. In addition, the driving element 423 needs to be configured as various types of driving devices, such as cylinders, electric cylinders, etc.

[0036] In one embodiment of this application, the second driving device 42 is a motor, which can drive the rotating body 41 to rotate synchronously by a set angle α each time; and, for each rotation of the rotating body 41 by a set angle α, the receiving slot 411 on it rotates forward to the position of the next adjacent receiving slot 411. The motor here can be set as a stepper motor, servo motor, etc., which can realize that the rotating body 41 is driven to rotate synchronously by a set angle α each time.

[0037] In one embodiment of this application, reference is made to Figure 4 The front end of the pusher 31 is configured with a V-shaped groove 311; the V-shaped groove 311 is adapted to the outer peripheral surface of the inner cylinder so that the inner cylinder can be stuck in the V-shaped groove 311 when the pusher 31 pushes the inner cylinder of the feed section 211 forward and laterally. When the pusher 31 pushes the inner cylinder forward, the front side wall of the inner cylinder is stuck in the V-shaped groove 311, which can prevent the front inner cylinder from deviating.

[0038] In one embodiment of this application, reference is made to Figure 5 The base 20 is equipped with a cover 22 to cover the turning section 213 of the discharge chute 21. The cover 22 can prevent the turning section 213 from dislodging from the discharge chute 21.

[0039] Furthermore, a baffle block 50 and an elastic element acting on the baffle block 50 are installed in the discharge section 212 of the discharge chute 21. When the first drive device 32 drives the inner cylinder in the discharge chute 21 to move forward, the inner cylinder in the discharge chute 21 can overcome the elastic force and push the baffle block 50 away. The baffle block 50 can elastically block the inner cylinder in the discharge section 212, so that the inner cylinders in the discharge chute 21 can be arranged in sequence and tightly. Each time the first drive device 32 pushes, the discharge chute 21 outputs one inner cylinder.

[0040] In one embodiment of this application, the inner cylinder discharge assembly has multiple hoppers 10, and the discharge channels 12 of the multiple hoppers 10 can all discharge material into the feed section 211 of the discharge chute 21. Figure 1 In the structure shown, the discharge channels 12 of the two hoppers 10 eventually converge and discharge material into the feed section 211 of the discharge chute 21. With this arrangement, when the inner cylinder of one hopper 10 is exhausted, the inner cylinders of the other hopper 10 can continue to discharge material, avoiding interruption.

[0041] This application embodiment also provides a fireworks production line, which includes the aforementioned inner cylinder discharge assembly. The inner cylinder discharge assembly includes a hopper 10, a base 20, and a pushing mechanism 30. The hopper 10 is provided with a material trough 11, and a material discharge channel 12 is provided at the bottom of the material trough 11. The base 20 is arranged below the hopper 10; the base 20 is provided with a discharge slide 21 suitable for the inner cylinder W to slide; the discharge slide 21 has a feeding section 211, a discharge section 212, and a turning section 213; the feeding section 211 is set as a horizontal slide suitable for the inner cylinder W to slide in a horizontal state; the discharge section 212 is set as a vertical slide suitable for the inner cylinder W to slide in a vertical state; the turning section 213 is located between the feeding section 211 and the discharge section 212, and smoothly turns and extends from the horizontal slide of the feeding section 211 to transition to the vertical slide of the discharge section 212, so that the inner cylinder W changes from a horizontal state to a vertical state after passing through the turning section 213; the feeding section 211 is located below the dropping channel 12 and can receive the inner cylinder W falling from the dropping channel 12. The pushing mechanism 30 includes a pushing component 31 and a first driving device 32. The first driving device 32 drives the pushing component 31 to push the inner cylinder W of the feeding section 211 laterally towards the discharge section 212, so that the discharge chute 21 outputs the inner cylinder W. As the discharge section 212 outputs the upright inner cylinder, the inner cylinder is pushed laterally into the mold in sequence for further filling into the fireworks tube. In the above-mentioned discharge process of the inner cylinder, the pushing component abuts against the side of the inner cylinder when pushing it, which is less likely to damage the inner cylinder and is safer.

[0042] Furthermore, the fireworks production line is equipped with multiple inner tube discharge assemblies. These assemblies can be used to output various types of inner tubes. It should also be noted that the types of fireworks inner tubes can be categorized based on the desired display effect (e.g., color, sound).
