Description

Technical Field

[0001] This utility model belongs to the field of fireworks production technology, and in particular relates to a fireworks inner tube buffer device, installation equipment and fireworks production line. Background Technology

[0002] In the fireworks production process, the inner tube cake typically needs to go through feeding, buffering, and distribution stages before entering the assembly process. Most existing inner tube buffering devices use a single vertical feeding method, that is, directly dropping the inner tube vertically into the distribution trough of the conveying component through the feeding channel. This method has the following drawbacks: First, the inner tube falls directly under gravity, which can easily generate a large impact. This may cause the inner tube to bounce, tilt, or even get stuck in the distribution trough, and may also damage the integrity of the tube, reducing the product yield. Second, existing devices often lack effective guiding and buffering structures. When the upstream continuously supplies material, the inner tube is prone to accumulation, misalignment, or even blockage at the feeding end, preventing the conveying component from distributing material properly and affecting the cycle time of subsequent processes. Third, although some devices have buffering components, their docking accuracy with the conveying component is poor, often resulting in the inner tube failing to fall accurately into the distribution trough; at the same time, without a matching auxiliary guiding component, the inner tube's falling posture is unstable, further increasing the risk of jamming.

[0003] Therefore, how to provide a device that can smoothly introduce the inner tube of fireworks and has buffering and material distribution functions is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0011] Furthermore, the guide section includes: a base plate, a first side plate, and a second side plate;

[0012] The base plate is set horizontally, with one end connected to the end of the first conveyor line and the other end connected to the inclined section;

[0013] The first and second side plates are symmetrically arranged on both sides of the base plate;

[0014] The tops of the first and second side plates extend towards the center to form a limiting part;

[0015] The limiting part extends away from the inclined section to form a guide part.

[0016] Furthermore, the cache components include: a third side panel, a fourth side panel, and a front panel;

[0017] The third and fourth side plates are respectively installed on both sides of the second conveyor line;

[0018] The front plate is located on the side away from the inclined section and between the third and fourth side plates; the bottom of the front plate is located above the material distribution trough and together with the top of the material distribution trough, the third side plate, and the fourth side plate to form the discharge port;

[0019] The vertical width of the discharge port is smaller than the diameter of the inner tube of the fireworks.

[0020] Furthermore, the cache component also includes a guide wheel;

[0021] The guide roller is rotatably positioned between the third and fourth side plates and at the discharge port below the front plate; the rolling surface of the guide roller is close to the top of the distribution trough.

[0023] The first sensor is located between the third side plate and the second conveyor line, and is used to detect the number of fireworks inner tubes in the material distribution trough.

When the buffer accumulates, it can temporarily store multiple firework inner tubes and release them one by one after aligning them with the distribution slots on the second conveyor line, achieving single-piece distribution. The buffer component guides the firework inner tubes one by one into the spaced distribution slots on the second conveyor line, ensuring that the firework inner tubes accurately enter the corresponding distribution positions, thereby improving the uniformity and reliability of distribution. Because the buffer component is located in the transition area, it also acts as a buffer, slowing down, orienting, and releasing the firework inner tubes one by one during movement, effectively preventing accumulation and jamming. The overall structure not only improves the continuity and automation of the conveying and distribution process but also reduces the need for manual intervention, enhancing the safety and stability of the production line operation. In summary, this application provides a firework inner tube buffer device that enables the smooth introduction of the firework inner tube and has buffering and material distribution functions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

If the specific posture changes, the directional indicators will also change accordingly. Furthermore, if the embodiments of this utility model involve descriptions such as "first," "second," "S1," "S2," "step one," "step two," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance, or implicitly indicating the number of technical features indicated or the execution order of the method. Those skilled in the art will understand that anything that does not violate the essential points of the utility model within the scope of its inventive concept should be included within the protection scope of this utility model.

[0047] This utility model provides a firework inner tube buffer device, reference. Figure 1 and Figure 2 ,include:

[0048] First conveyor line 1 is used to transport the inner tube of the fireworks;

[0049] The second conveyor line 2 is located below the first conveyor line 1 and includes a material distribution trough 21 spaced apart for receiving the inner tube of the fireworks and transferring it to the next process.

[0050] The buffer component 3 is located in the transition area between the first conveyor line 1 and the second conveyor line 2, and is disposed on the second conveyor line 2, for guiding the inner tube of the fireworks from the first conveyor line 1 into the material distribution trough 21 of the second conveyor line 2.

[0051] In this embodiment, a firework inner tube buffer device is provided. A buffer component is set between the first conveyor line and the second conveyor line, so that when the firework inner tube is transferred from the end of the first conveyor line (discharge end) to the beginning of the second conveyor line (inlet end), it can be buffered, guided, and limited by the buffer component, avoiding the problems of unstable posture and excessive impact caused by direct drop. When the buffer is accumulating, it can temporarily store multiple firework inner tubes and release them one by one after aligning with the material distribution slot of the second conveyor line, realizing single-piece material distribution. The buffer component guides the firework inner tubes one by one into the spaced material distribution slots on the second conveyor line, ensuring that the firework inner tubes can accurately enter the corresponding material distribution position, thereby improving the uniformity and reliability of material distribution. Since the buffer component is located in the transition area, it also plays a buffering role, causing the firework inner tubes to decelerate, orient, and release one by one during the movement, effectively preventing accumulation and jamming. The overall structure not only improves the continuity and automation of the conveying and material distribution process, but also reduces the need for manual intervention and enhances the safety and stability of the production line operation. In summary, this application provides a firework inner tube buffer device that enables the smooth introduction of the firework inner tube and has buffering and material distribution functions.

[0052] Preferred, Reference Figure 3 and Figure 4 A flow guiding component 4 is provided at the end of the first conveyor line 1;

[0053] The flow guiding component 4 includes: a guiding section 41 and an inclined section 42;

[0054] Guide section 41 is used to guide the fireworks into the inner tube;

[0055] The inclined section 42 is positioned above the second conveyor line, with its end extending into the buffer assembly 3 and close to the top of the material distribution trough 21 of the second conveyor line 2.

[0056] In this embodiment, the guiding component includes a guiding section and an inclined section. The guiding section is used to initially guide the inner tubes of fireworks conveyed on the first conveyor line, ensuring their relatively stable posture when entering the inclined section. The inclined section is located above the second conveyor line, with its end extending into the buffer component and close to the top of the distribution trough of the second conveyor line. After entering the inclined section via the guiding section, the inner tubes of fireworks change from linear conveying motion to sliding motion along the inclined surface under the guidance of the inclined section, achieving a gradual reduction in speed and a gradual adjustment of posture. When sliding to the end of the inclined section, the inner tubes of fireworks fall directly into the buffer component and are finally accurately guided into the distribution trough of the second conveyor line. By adding a guiding component to the inner tube buffer device, the inner tubes of fireworks slide into the distribution trough of the second conveyor line under the guidance of the guiding component. The sliding process has a controlled speed and direction, and the inner tubes of fireworks can be released one by one in the buffer component, forming a continuous and controllable transition process. This makes the three links of conveying, buffering, and distribution closely connected, significantly improving the distribution efficiency and automation level. For example, the inclined section can be a sloping plate structure, allowing the inner cylinder to slide and roll into the distribution trough under gravity; the inclined section can also be other arc-shaped or curved structures to achieve a better rolling effect. More preferably, the inclined section and the guide section are rotatably connected, thereby adjusting the inclination angle of the inclined section.

[0057] Preferred, Reference Figure 3 and Figure 4 The guide section 41 includes: a base plate 411, a first side plate 412, and a second side plate 413;

[0058] The base plate is set horizontally 411, with one end connected to the end of the first conveyor line 2 and the other end connected to the inclined section 42;

[0059] The first side plate 412 and the second side plate 413 are symmetrically arranged on both sides of the base plate 411;

[0060] The top of the first side plate 412 and the second side plate 413 extend toward the center to form a limiting part 414;

[0061] The limiting part 414 extends away from the inclined section 42 to form the guide part 415.

[0062] In this embodiment, the guide section is equipped with a base plate and symmetrical first and second side plates, allowing the incoming firework inner tube to roll stably along the base plate and preventing rolling deviation during the introduction process. The tops of the first and second side plates extend towards the center to form limiting portions, which can limit the vertical position of the firework inner tube, effectively preventing tilting or tumbling. The limiting portions extend away from the inclined section to form guide portions, accurately guiding the firework inner tube. One end of the base plate is connected to the end of the first conveyor line, and the other end is connected to the inclined section, allowing the firework inner tube to smoothly transition to the inclined section after horizontal introduction and enter the distribution trough of the second conveyor line through the inclined section, achieving smooth conveying. The distance between the guide portion, the limiting portion, and the base plate can be set by those skilled in the art based on the diameter of the firework inner tube.

[0063] Preferred, Reference Figures 1-3 and Figure 5 The cache component 3 includes: a third side plate 31, a fourth side plate 32, and a front plate 33;

[0064] The third side plate 31 and the fourth side plate 32 are respectively disposed on both sides of the second conveyor line 2;

[0065] The front plate 33 is located on the side away from the inclined section 42 and between the third side plate 31 and the fourth side plate 32; the bottom of the front plate 33 is located above the material distribution trough 21 and forms a discharge port 34 with the top of the material distribution trough 21, the third side plate 31 and the fourth side plate 32.

[0066] The vertical width of the discharge port 34 is smaller than the diameter of the inner tube of the fireworks.

[0067] In this embodiment, the buffer assembly includes a third side plate, a fourth side plate, and a front plate, forming a buffer chamber capable of buffering the inner tube of the fireworks. The third and fourth side plates of the buffer assembly are respectively arranged on both sides of the second conveyor line, creating an effective limiting space in the lateral direction to ensure that the incoming inner tube of the fireworks does not shift to either side. The front plate is located on the side away from the inclined section, between the third and fourth side plates. The bottom of the front plate is above the distribution chute and, together with the top of the distribution chute, the third side plate, and the fourth side plate, forms a discharge port, thereby limiting the buffer space of the inner tube in the longitudinal direction. The vertical width of the discharge port is smaller than the diameter of the inner tube of the fireworks, ensuring that each individual inner tube falling into the distribution chute passes through the discharge port via the distribution chute on the second conveyor line. This buffer assembly can reliably buffer and orderly distribute the inner tube of the fireworks, avoiding simultaneous discharge of multiple tubes or jamming, ensuring the stable posture of the inner tube of the fireworks during the discharge process, and achieving smooth and continuous conveying of the inner tube of the fireworks.

[0068] Example, reference Figure 2The second conveyor line 2 includes: a second conveyor belt 22, and material distribution blocks 23 arranged circumferentially on the second conveyor belt 22;

[0069] A material distribution trough 21 is formed between adjacent material distribution blocks 23; the front plate 33, the top of the material distribution trough 21, the third side plate 31 and the fourth side plate 32 together form a discharge port 34;

[0070] The vertical width between the bottom of the front plate 33 and the top of the material distribution block 23 and the top of the material distribution trough 21 is smaller than the diameter of the inner tube of the fireworks.

[0071] In this embodiment, circumferentially spaced material distribution blocks on the second conveyor belt form a material distribution trough, providing stable support for the inner tube of the firework during conveying and preventing lateral shifting or tilting. The front plate, the top of the material distribution trough, and the first and second side plates together form the discharge port. The vertical width between the bottom of the front plate and the top of the material distribution blocks and the top of the material distribution trough is less than the diameter of the inner tube of the firework, thereby ensuring that only a single inner tube can pass smoothly through the discharge port at any one time, preventing multiple tubes from passing through simultaneously or getting stuck.

[0072] Preferred, Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 The cache component 3 also includes a guide roller 35;

[0073] The guide roller 35 is rotatably disposed between the third side plate 31 and the fourth side plate 32, and located at the discharge port 34 below the front plate 33; the rolling surface of the guide roller 35 is close to the top of the distribution trough 21.

[0074] In this embodiment, a guide roller is provided at the discharge port of the buffer component, located between the third and fourth side plates; the rolling surface of the guide roller is close to the top of the distribution trough. When the inner tube of the firework passes through the discharge port, the roller guides the inner tube by rolling, ensuring that the inner tube falls accurately into the distribution trough. Through the guiding action of the guide roller, the inner tube of the firework will not shift or tilt during the distribution process, further avoiding jamming problems.

[0075] Preferred, Reference Figure 5 and Figure 6 The cache component 3 also includes: a first sensor, a second sensor 36, and a controller;

[0076] The first sensor is set between the third side plate 31 and the second conveyor line 2 to detect the number of fireworks inner tubes in the material distribution trough 21.

[0077] The second sensor 36 is used to detect the stacking height of the fireworks inner tube inside the buffer assembly 3;

[0078] The controller is connected to the first sensor, the second sensor 36 and the first conveyor line 1, and controls the start and stop and the conveying speed of the first conveyor line 1 based on the detection data of the first sensor and the second sensor 36.

[0079] In this embodiment, a first sensor and a second sensor are added to the fireworks inner tube buffer device to detect the number of fireworks inner tubes in the distribution trough and the stacking height of the inner tubes in the buffer assembly in real time. The controller adjusts the start / stop and conveying speed of the first conveyor line based on the detection data from the first and second sensors, achieving precise control of the fireworks inner tube conveying rhythm. For example, when there are too many fireworks inner tubes in the distribution trough or buffer assembly, the controller can pause or slow down the conveying of fireworks inner tubes by the first conveyor line to avoid blockage or accumulation; when there are insufficient inner tubes in the distribution trough or buffer assembly, the controller starts or speeds up the conveying of fireworks inner tubes by the first conveyor line to ensure continuous supply. This closed-loop control method effectively avoids unstable inner tube stacking or material interruption, improving the stability and automation level of the buffering and distribution process. It is worth noting that the key to this application is providing a fireworks inner tube buffer device. The buffering and distribution of fireworks inner tubes from a mechanical structure perspective, as well as the specific controller's control algorithm, recognition algorithm, the detection method of the first sensor and the detection method of the second sensor, and the control flow, can be implemented by programmable logic devices such as PLCs or existing algorithms or technologies, and will not be elaborated here.

[0080] More preferably, refer to Figure 3 and Figure 5 The second sensor 36 is mounted at the bottom of the front panel 33 and aligned horizontally with the guide section 41 to accurately detect in real time whether the buffered firework inner tube is higher than the height of the guide section. When the detected accumulation height reaches or exceeds a set value (e.g., higher than the height of the guide section), the controller can immediately adjust the start / stop or conveying speed of the first conveyor line to avoid material overflow or blockage caused by excessive accumulation. For example, the first and second sensors can be selected as position sensors such as diffuse reflection sensors, grayscale sensors, and brightness displacement sensors to monitor whether the firework inner tube has reached the designated position.

[0081] Preferred, Reference Figure 3 , Figure 5 and Figure 7 The buffer component 3 also includes a first link 37 and a pressure chain 38;

[0082] The first connecting rod 37 passes between the third side plate 31 and the fourth side plate 32, and is located above the inclined section 42;

[0083] One end of the pressing chain 38 is fixed to the first connecting rod 37, and part of the pressing chain 38 overlaps the top of the material distribution trough 21.

[0084] In this embodiment, one end of the pressure chain is fixed to the first connecting rod, partially overlapping the top of the distribution trough, applying moderate pressure to the inner cylinder of the firework that has not yet entered the distribution trough. The portion of the pressure chain overlapping the top of the distribution trough can be the other end of the pressure chain, or the drooping portion between the first and second connecting rods (described later). Because the pressure chain is flexible, it can finely adjust the force and undergo moderate deformation according to changes in the diameter and position of the inner cylinder, achieving adaptive adjustment. Under the continuous conveying action of the second conveyor line, the pressure chain can smoothly push the inner cylinder of the firework into the distribution trough. This flexible pressure method not only prevents the inner cylinder from jumping, tilting, or overturning in the buffer assembly or distribution trough, but also moderately guides the movement direction of the inner cylinder at the outlet. Compared with a rigid guide structure, the pressure chain can effectively absorb the impact force generated during the movement of the inner cylinder, avoiding damage to the cylinder body, while ensuring that the inner cylinder is smoothly conveyed along a predetermined trajectory. As a result, the pressing chain significantly improves the safety, continuity, and conveying reliability of the fireworks inner tube during the buffering, dispensing, and discharge processes, achieving efficient and stable operation of the entire feeding device.

[0085] Preferred, Reference Figure 3 , Figure 5 and Figure 8 The cache component 3 also includes a second link 39 disposed on one side of the first link 37;

[0086] One end of the pressure chain 38 is fixed to the first connecting rod 37, and the other end is fixed to the second connecting rod 39;

[0087] The length of the pressing chain 38 is greater than the distance between the first link 37 and the second link 39, and the hanging part of the pressing chain 38 overlaps the top of the material distribution trough 21.

[0088] In this embodiment, a second connecting rod is added within the buffer assembly, and the length of the pressure chain is greater than the distance between the first and second connecting rods, allowing the drooping portion of the pressure chain to naturally overlap the top of the distribution trough. Compared to a configuration where one end is fixed and the other only falls, this structure with both ends of the pressure chain fixed allows the pressure chain to maintain a stable drooping shape and stress state during the distribution process, achieving a more uniform and controllable flexible pressure effect and guiding the inner cylinder of the fireworks into the distribution trough.

[0089] This application also provides a fireworks inner tube installation device, including any of the above-mentioned fireworks inner tube buffer devices.

[0090] In this embodiment, a fireworks inner tube installation device is provided, employing any of the aforementioned fireworks inner tube buffer devices for installing the fireworks inner tubes within the fireworks outer tube. The fireworks inner tube buffer device, through effective buffering and distributing of the fireworks inner tubes, ensures that each inner tube maintains a stable posture before being installed into the fireworks outer tube, preventing tilting, overturning, or misalignment. Simultaneously, the buffering, distributing, and conveying mechanisms of the fireworks inner tube buffer device guarantee a continuous supply of fireworks inner tubes at a predetermined rhythm, thereby improving the efficiency, uniformity, and accuracy of the fireworks installation process.

[0091] This application also provides a fireworks production line, including the aforementioned fireworks inner tube installation equipment.

[0092] This embodiment provides a fireworks production line employing any of the aforementioned fireworks inner tube installation equipment. Specifically, the fireworks production line includes a main conveyor belt and, sequentially arranged along the main conveyor belt, a gunpowder filling device, a bottom paper pressing device, a fireworks inner tube installation device, and a top paper pressing device. These devices are arranged sequentially on the main conveyor belt, and through reasonable process connections, the automation and continuity of fireworks production can be achieved. Specifically, the gunpowder filling device quantitatively fills a predetermined dose of gunpowder into the bottom of the fireworks outer tube, providing the power foundation for subsequent inner tube installation and ignition. The bottom paper pressing device covers and presses the bottom paper after the gunpowder filling is completed, ensuring the fixation of the gunpowder and the stability of combustion. The fireworks inner tube installation device employs the aforementioned fireworks inner tube buffer device to achieve stable feeding and accurate filling of the inner tube. The top paper pressing device seals and presses the filled fireworks, thereby ensuring the overall structural stability and safety of the finished fireworks. This fireworks production line can significantly improve the efficiency of fireworks production and achieve automated fireworks production.

[0093] The aforementioned fireworks inner tube installation equipment and fireworks production line are created based on the aforementioned fireworks inner tube buffer device. The combination of their technical effects and features will not be elaborated further here. The above embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
