Description

Technical Field

[0001] This utility model relates to the field of fireworks testing equipment technology, and in particular to a paper tube fireworks fuse testing device. Background Technology

[0002] In automated fireworks production lines, after the paper tube fireworks are assembled, they enter the fireworks fuse inspection process to check the installation quality and condition of the fuse (firework fuse) and ensure product safety. Simultaneously, the feeding section of the fireworks fuse inspection equipment must precisely align with the unloading end of the upstream assembly machine to ensure the paper tube fireworks can be transferred smoothly and stably.

[0003] The stacking machine operates by assembling a row of firework paper tubes. First, a row of paper tubes is assembled, then the assembled row is conveyed to a receiving platform. The platform is then lowered by the outer diameter of one paper tube, and the next row of paper tubes is stacked on top of the previous row. This process is repeated to obtain a preset number of stacked firework paper tubes. As a result, the absolute height of the feeding end of the stacking machine changes dynamically with the total thickness (i.e., the number of layers) of the stacked firework paper tubes. This causes the relative position (especially the vertical height) between the feeding end of the stacking machine and the feeding end of the lead wire detection equipment to be inconsistent. When producing firework paper tubes of different layer specifications, the heights of the two will be misaligned, thus affecting the continuity of material conveying and positioning accuracy.

[0004] To solve the above problems, those skilled in the art mainly use two methods: raising the frame and driving the entire worktable (including the feeding unit, detection unit, and unloading unit) to rise and fall via a lifting mechanism, so that the feeding end of the lead wire detection equipment matches the current unloading height of the assembly machine.

[0005] However, due to the bulky structure of the lead wire testing equipment, raising the frame presents several drawbacks: cumbersome operation, high manpower and time consumption, low production line changeover efficiency, and the risk of operator injury during the lifting process. Driving the entire worktable to lift and lower is also problematic, as it requires powering a large platform assembly containing numerous components, resulting in high energy consumption, a short lifting stroke, and poor flexibility, making it difficult to achieve rapid and precise height-following docking. Utility Model Content

[0006] Therefore, it is necessary to provide a paper tube firework fuse detection device that can be easily, safely, and flexibly adapted to changes in the feeding height of the assembling machine.

[0007] A paper tube firework fuse testing device includes a frame, a main workbench, a testing mechanism, a feeding platform, and a lifting drive mechanism; The main workbench is fixedly mounted on the frame; The detection mechanism is installed on the frame and is used to detect the fuse of the paper tube fireworks on the main workbench; The feeding platform is slidably mounted on the frame; The lifting drive mechanism drives the feeding platform to lift relative to the frame, so that the feeding platform can dock with the pot assembly machine and / or the main worktable to transport the paper tube fireworks after the pot assembly machine has assembled the pots to the main worktable.

[0008] The aforementioned paper tube firework fuse testing equipment separates the feeding platform and the main worktable, and the lifting drive mechanism only drives the feeding platform for independent lifting. This significantly reduces the load mass of the lifting drive, thereby significantly reducing the energy consumption of the lifting drive mechanism. Simultaneously, by using only the feeding platform as the lifting component, the weight of the lifting component is greatly reduced, effectively improving the flexibility and response speed of the lifting process. This allows for rapid adaptation to height changes at the unloading end of the assembly machine, solving the problem of height inconsistency between the unloading end of the assembly machine and the main worktable.

[0009] Since it only requires a lifting and feeding platform, its structure is relatively lightweight and can adopt a lifting drive mechanism with a larger stroke. Therefore, the lifting and adjustment range of the feeding platform is much greater than that of the traditional workbench overall lifting scheme. It can be used for various feeding heights when the assembly machine produces paper tube fireworks of different layers (especially multi-layered ones), which greatly improves the versatility and applicability of the paper tube fireworks fuse detection equipment.

[0010] The lifting and lowering loading platform automatically adjusts the docking height, completely replacing the manual operation method of changing the overall height by raising the frame in the existing technology. This not only eliminates the cumbersome process of moving heavy machines and adding pads, thus significantly shortening product changeover time and improving production efficiency, but also completely eliminates the safety hazards such as tipping and crushing personnel that may be caused by lifting heavy equipment, ensuring the personal safety of operators.

[0017] Figure 1 This illustration shows the state of the paper tube firework fuse detection device when it is connected to the assembly machine in one embodiment of this utility model. Figure 2 and Figure 3The accompanying drawings illustrate the structure of a paper tube firework fuse detection device according to an embodiment of the present invention from two different perspectives. For ease of explanation, the drawings only show structures relevant to embodiments of the present invention.

[0018] Please see Figures 1 to 3 The paper tube firework fuse testing device 100 in the preferred embodiment of this utility model includes a frame 110, a main workbench 120, a testing mechanism 130, a feeding platform 140, and a lifting drive mechanism 150.

[0019] The main workbench 120 is fixedly mounted on the frame 110. The detection mechanism 130 is mounted on the frame 110 and is used to detect the fuses of the paper tube fireworks on the main workbench 120. The detection mechanism 130 can be an industrial camera, infrared thermal imager, etc.

[0020] The feeding platform 140 is slidably mounted on the frame 110. A lifting drive mechanism 150 drives the feeding platform 140 to rise and fall relative to the frame 110, allowing the feeding platform 140 to dock with the container assembly machine 10 and / or the main worktable 120, conveying the paper tube fireworks after container assembly by the container assembly machine 10 to the main worktable 120. The lifting drive mechanism 150 is connected to the feeding platform 140 via a transmission connection.

[0021] Specifically, when there is a height difference between the main worktable 120 and the unloading end of the basin setter 10, the lifting drive mechanism 150 drives the loading platform 140 to rise and fall, so that the loading platform 140 can dock with the unloading end of the basin setter 10, or dock with the main worktable 120; when the height between the main worktable 120 and the unloading end of the basin setter 10 is the same, the lifting drive mechanism 150 drives the loading platform 140 to rise and fall, so that the two ends of the loading platform 140 can dock with the unloading end of the basin setter 10 and the main worktable 120 respectively.

[0022] In addition, when the paper tube firework fuse detection device 100 is located on a horizontal plane, the upper surfaces of the main workbench 120 and the feeding platform 140 are both horizontal planes, both used to place paper tube firework fuses, and the lifting direction of the feeding platform 140 is vertical.

[0023] In practical applications, when the height of the main workbench 120 is inconsistent with the height of the feeding end of the assembly machine 10, the process of using the aforementioned paper tube firework fuse detection device 100 to detect the fuse of the paper tube firework fuse delivered by the assembly machine 10 is as follows: (1) The lifting drive mechanism 150 drives the feeding platform 140 to rise or fall until the feeding platform 140 is connected to the unloading end of the assembly machine 10. At this time, the paper tube fireworks assembled on the assembly machine 10 are smoothly and smoothly fed into the feeding platform 140 under the power provided by the assembly machine 10, thus realizing the feeding of the paper tube fireworks. (2) The lifting drive mechanism 150 is used to drive the loading platform 140 to descend or rise until the loading platform 140 is connected to the main worktable 120. At this time, under the power provided by the loading platform 140 or the power provided by the assembly machine 10 when the paper tube fireworks are lined up and fed in, the paper tube fireworks on the loading platform 140 are smoothly and steadily transported to the main worktable 120. (3) Use the testing mechanism 130 to test the fuse of the paper tube fireworks on the main workbench 120.

[0024] When the height of the main workbench 120 is the same as the height of the feeding end of the assembly machine 10, the process of using the aforementioned paper tube firework fuse detection equipment 100 to detect the fuse of the paper tube firework fuse delivered by the assembly machine 10 is as follows: (1) The lifting drive mechanism 150 drives the loading platform 140 to rise or fall until the two ends of the loading platform 140 are respectively connected to the main workbench 120 and the unloading end of the assembly machine 10. The paper tube fireworks after being assembled on the assembly machine 10 are smoothly and steadily fed onto the loading platform 140 under the power provided by the assembly machine 10, thus realizing the loading of paper tube fireworks. (2) The paper tube fireworks on the feeding platform 140 are transported to the main worktable 120 under the power provided by the feeding platform 140 or the power provided by the assembly machine 10 when the paper tube fireworks are lined up and fed in. (3) Use the testing mechanism 130 to test the fuse of the paper tube fireworks on the main workbench 120.

[0025] It should be noted that the power for the paper tube fireworks to enter the feeding platform 140 is provided by the assembly machine 10; the power for the paper tube fireworks to enter the main worktable 120 from the feeding platform 140 is provided by the feeding platform 140, or the power provided by the assembly machine 10 pushes the paper tube fireworks in sequence.

[0026] The aforementioned paper tube firework fuse testing equipment 100 separates the feeding platform 140 and the main worktable 120, and the lifting drive mechanism 150 only drives the feeding platform 140 for independent lifting. This significantly reduces the load mass of the lifting drive, thereby significantly reducing the energy consumption of the lifting drive mechanism 150. Simultaneously, by using only the feeding platform 140 as the lifting component, the mass of the lifting component is greatly reduced, effectively improving the flexibility and response speed of the lifting process. This allows for rapid adaptation to height changes at the discharge end of the assembly machine 10, solving the problem of height inconsistency between the discharge end of the assembly machine 10 and the main worktable 120.

[0027] Since only the lifting and feeding platform 140 is needed, its structure is relatively lightweight and can adopt a lifting drive mechanism 150 with a larger stroke. Therefore, the lifting and adjustment range of the feeding platform 140 is much greater than that of the traditional overall lifting scheme of the workbench. It can be used for various feeding heights when the assembly machine 10 produces paper tube fireworks of different layers (especially multiple layers), which greatly improves the versatility and applicability of the paper tube fireworks fuse detection equipment 100.

[0028] The adjustable loading platform 140 automatically adjusts the docking height, completely replacing the manual operation method of raising the frame 110 to change the overall height in the existing technology. This not only eliminates the cumbersome process of moving heavy machines and adding pads, thus significantly shortening product changeover time and improving production efficiency, but also completely eliminates the safety hazards such as tipping and crushing personnel that may be caused by lifting heavy equipment, ensuring the personal safety of operators.

[0029] Moreover, the loading platform 140 is raised and lowered independently, while the main worktable 120 remains fixed, avoiding the disturbance or deviation that may be caused to the detection accuracy due to the frequent raising and lowering of the entire worktable during the traditional overall lifting process, thus improving the reliability of detection accuracy.

[0030] In some embodiments, the lifting drive mechanism 150 includes a drive motor 151 and a transmission assembly 152. The drive motor 151 is connected to the loading platform 140 via the transmission assembly 152. The transmission assembly 152 may be a lead screw assembly, a sprocket and chain assembly, etc. The drive motor 151 and the transmission assembly 152 work together to ensure the smoothness and responsiveness of the lifting action of the loading platform 140, achieve stepless adjustment of the lifting height, significantly improve the accuracy of lifting positioning and load-bearing stability, and also compensate for axial deviations caused by manufacturing and installation, reducing the requirements for assembly precision and minimizing maintenance workload.

[0031] Further, in some embodiments, the transmission assembly 152 includes a transmission rod 1521, two sprockets 1522, two chains 1523, and two counterweights 1524. The transmission rod 1521 is driven by a drive motor 151. Both ends of the transmission rod 1521 are rotatably mounted on the frame 110 and located above the loading platform 140. The two sprockets 1522 are driven by the two ends of the transmission rod 1521. The two chains 1523 are wound around and meshed with the two sprockets 1522. One end of each chain 1523 is connected to both sides of the loading platform 140, and the other end is connected to the two counterweights 1524. The counterweights 1524 are suspended. Thus, the counterweights 1524 and the loading platform 140 are suspended on the corresponding sprockets 1522 via the chains 1523, and the counterweights 1524 are used to balance the lifting and lowering process of the loading platform 140.

[0032] Thus, by configuring the transmission assembly 152 as a transmission rod 1521, two sprockets 1522, two chains 1523, and two counterweights 1524, the loading platform 140 can be simultaneously pulled up or lowered from both sides by a single drive motor 151, ensuring the balance of the loading platform 140 during lifting and lowering. Furthermore, the counterweights 1524 also reduce the load on the drive motor 151.

[0033] Furthermore, in some embodiments, the paper tube firework fuse detection device 100 also includes two protective housings 160. Both protective housings 160 are mounted on the frame 110 and located on opposite sides of the feeding platform 140. At least a portion of the counterweight 1524 is located within the protective housing 160. The protective housing 160 is configured to define the position of the counterweight 1524 in the feeding direction of the feeding platform 140. The protective housing 160 can be a cylindrical shell structure, such as a round tube or square tube, or a U-shaped groove shell, rectangular groove shell, or other groove shell structure.

[0034] The protective shell 160 is mainly used to limit the position of the counterweight 1524 in the feeding direction of the feeding platform 140, so as to prevent the counterweight 1524 from swinging back and forth and injuring surrounding personnel or objects when it descends or rises with the feeding platform 140, thereby further improving the safety of the paper tube firework fuse detection equipment 100.

[0035] In some embodiments, the paper tube firework fuse detection device 100 further includes a guide member 171 disposed on the frame 110. The feeding platform 140 is configured to be slidably connected to the frame 110 via the guide member 171. The guide member 171 can be a guide rail, guide groove, etc., disposed on the frame 110. Specifically, in this embodiment, the guide member 171 is a linear guide rail. The guide member 171 is used to guide the lifting path of the feeding platform 140, thereby improving the height adjustment accuracy of the feeding platform 140.

[0036] Furthermore, in some embodiments, the paper tube firework fuse detection device 100 also includes an upper limit block 172 and a lower limit block 173. The upper limit block 172 and the lower limit block 173 are respectively fixed to the upper and lower ends of the guide member 171. The upper limit block 172 and the lower limit block 173 limit the highest and lowest limit positions of the lifting and lowering of the feeding platform 140, respectively, and also prevent the feeding platform 140 from sliding out of the guide member 171, thereby improving the safety and reliability of the paper tube firework fuse detection device 100.

[0037] In some embodiments, the paper tube firework fuse detection device 100 further includes two guiding structures 180. The two guiding structures 180 are disposed opposite to each other and spaced apart on the feeding platform 140. A guide channel is formed between the two guiding structures 180 and the upper surface of the feeding platform 140 for guiding the feeding direction of the paper tube firework fuse.

[0038] In actual use, when the feeding platform 140 rises or falls under the drive of the lifting drive mechanism 150 to dock with the unloading end of the assembly machine 10, the assembled paper tube fireworks on the assembly machine 10 will enter the guide channel 190 on the feeding platform 140 under the power provided by the assembly machine 10. Then, when the feeding platform 140 docks with the main worktable 120, the paper tube fireworks in the guide channel 190 are pushed in by the paper tube fireworks behind during the queuing feeding or pushed into the main worktable 120 by the power of the feeding platform 140 itself, so as to facilitate the detection mechanism 130 to accurately detect them.

[0039] Therefore, the two guiding structures 180 guide the feeding direction and placement posture of the paper tube fireworks on the feeding platform 140, so that the paper tube fireworks can enter the main workbench 120 in the correct posture after being guided by the guiding channel 190. This ensures that the detection mechanism 130 can accurately and reliably detect the lead wire condition in each paper tube of the paper tube fireworks, further improving the accuracy and reliability of the paper tube fireworks lead wire detection equipment 100.

[0040] Furthermore, in some embodiments, the guiding structure 180 includes a guiding plate 181 and a mounting plate 182 disposed at one end of the guiding plate 181. The two guiding plates 181 are arranged opposite each other and spaced apart. Each mounting plate 182 has an elongated through hole 1821 along the spacing direction of the two guiding plates 181. A connector passes through the elongated through hole 1821. The connector is detachably connected to the loading platform 140 to detachably connect the guiding structure 180 and the loading platform 140. The connector can be a bolt, screw and nut assembly, etc.

[0041] Thus, by adjusting the position of the connector in the elongated through hole 1821, the spacing between the two guiding structures 180 can be adjusted, so that the guiding channel 190 can not only ensure that the paper tube firework can enter the main worktable 120 in the correct position, but also adapt to the guiding needs of paper tube firework of different sizes.

[0042] Furthermore, in some embodiments, the end of the guide plate 181 away from the main worktable 120 is bent in a direction opposite to the other guide plate 181, so that the opening of the guide channel away from the main worktable 120 is trumpet-shaped. That is, the size of the opening of the guide channel 190 away from the main worktable 120 gradually increases in the direction from the main worktable 120 to the feeding platform 140, so as to ensure that the paper tube fireworks fed by the assembly machine 10 can accurately enter the guide channel 190 even if there is a slight deviation in the conveying direction or position, which further improves the accuracy and reliability of the paper tube fireworks lead detection device 100.

[0043] In some embodiments, the loading platform 140 includes a lifting seat 141 and a first belt conveyor mechanism 142. The lifting seat 141 is slidably mounted on the frame 110 and is connected to the lifting drive mechanism 150. The first belt conveyor mechanism 142 is mounted on the lifting seat 141, and its unloading end can dock with the main worktable 120.

[0044] Thus, when the assembly machine 10 feeds the assembled paper tube fireworks onto the feeding platform 140, the paper tube fireworks directly enter the conveyor belt of the first belt conveyor mechanism 142, and the first belt conveyor mechanism 142 provides power for the movement of the paper tube fireworks on the feeding platform 140, so that the paper tube fireworks on the feeding platform 140 can automatically enter the main worktable 120, so as to ensure that the paper tube fireworks can move flexibly on the feeding platform 140 without relying on external power (such as the power provided by the assembly machine 10).

[0045] When the paper tube firework fuse detection device 100 includes two guiding structures 180, the guiding structures 180 are installed on the support frame of the first belt conveyor mechanism 142.

[0046] Further, in some embodiments, the main workbench 120 includes a second belt conveyor 121, a third belt conveyor 122, a feeding and pushing mechanism 123, and a limiting stop 124. The second belt conveyor 121, the third belt conveyor 122, and the feeding and pushing mechanism 123 are all mounted on the frame 110. The feeding end of the second belt conveyor 121 can dock with the feeding platform 140. The feeding end of the third belt conveyor 122 is located on one side of the second belt conveyor 121. The conveying direction of the third belt conveyor 122 is intersected with the conveying direction of the second belt conveyor 121. The feeding and pushing mechanism 123 is configured to push the paper tube fireworks on the second belt conveyor 121 onto the third belt conveyor 122. The limiting stop 124 is laterally positioned at the end of the second belt conveyor 121 away from the feeding platform 140 and is located above the conveyor belt of the second belt conveyor 121. The feeding and pushing mechanism 123 can be an assembly including a drive cylinder and a pushing plate disposed at the movable end of the drive cylinder, or it can be an assembly including a drive component (such as a motor, electric cylinder, hydraulic cylinder, etc.) and a feeding structure that is connected to the drive component for transmission, etc.

[0047] Specifically, when the loading platform 140 includes a lifting seat 141 and a first belt conveyor mechanism 142, the unloading end of the second belt conveyor mechanism 121 can be connected with the loading end of the first belt conveyor mechanism 142, and the conveying directions of the two are consistent. The limiting stop bar 124 is laterally arranged at the end of the second belt conveyor mechanism 121 away from the first belt conveyor mechanism 142.

[0048] Thus, the main workbench 120 is used by the detection mechanism 130 to perform lead wire detection and subsequent unloading of the paper tube fireworks. These two functions are respectively implemented by the independently set second belt conveyor 121 and third belt conveyor 122. When the loading platform 140 docks with the main workbench 120, the unloading end of the first belt conveyor 142 can dock with the loading end of the second belt conveyor 121. Therefore, the first belt conveyor 142 operates to transport the paper tube fireworks on the loading platform 140 to the conveyor belt of the second belt conveyor 121. The second belt conveyor 121 operates to move the paper tube fireworks to the position of the limit stop 124 (i.e., the paper tube fireworks contact the limit stop 124 to limit the final position of the paper tube fireworks on the second belt conveyor 121), so as to facilitate the detection mechanism 130 to accurately detect the paper tube fireworks. After the inspection is completed, the feeding and pushing mechanism 123 pushes the inspected paper tube fireworks on the second belt conveyor 121 onto the conveyor belt of the third belt conveyor 122. The third belt conveyor 122 runs to drive the paper tube fireworks away from the second belt conveyor 121, thereby realizing the automatic feeding of the inspected paper tube fireworks.

[0049] In addition, the limit stop bar 124 can also prevent the second belt conveyor mechanism 121 from moving the paper tube firework ball excessively, thus avoiding the paper tube firework ball from falling off the second belt conveyor mechanism 121 and improving the safety and reliability of the fuse detection.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations 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 various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
