Description

Technical Field

[0001] The utility model relates to the field of fireworks production, in particular to a device for automatically loading powder into a packaged inner tube of a combined fireworks effect. Background Art

[0002] In the fireworks industry, the pyrotechnic powder used to explode the inner tube of an effect and ignite the effect charge is called a "opening charge." Conventional technology often involves manual loading, which is slow and inefficient. It also creates direct contact between people and the charge, creates a poor working environment, and presents numerous safety hazards. Automated fireworks charging lines are urgently needed to replace manual operations. The amount of opening charge in a single shot of an effect tube ranges from 1 to 5 grams, with a tolerance of ±10%. Therefore, precise control of the metering of the opening charge is crucial during the production process.

[0003] The existing patent 202310461460.3 discloses a scraper mechanism and a loading device for a fireworks effect inner tube cake, which specifically discloses a loading box, a lifting mechanism, a scraper assembly arranged on the lifting mechanism for horizontal movement, and a dividing template with a storage hole arranged in the loading box. The scraper assembly includes a slide rod and a scraper installed at the end of the slide rod. The scraper is arranged in the loading box. The dividing template is also provided with a stacking area for stacking medicine. The scraper reciprocates on the dividing template and allows the medicine in the stacking area to enter the storage hole. This technical solution sweeps the medicine into the storage hole of the batching mold, realizes precise loading, reduces the turnover of medicine during work, avoids the accumulation of medicine in the batching mold and brings safety hazards, and saves materials at the same time. While this technical solution reduces drug accumulation by utilizing the reciprocating motion of the scraper, it relies on a material distribution cylinder and a lifting motor to achieve both lifting and scraping of the scraper. This requires adjusting the scraper's height during each reciprocating stroke to ensure proper scraping, making this method relatively cumbersome to control. This technical solution, however, eliminates the need for adjusting the scraper's height during a single stroke through the reciprocating pusher mechanism. Instead, the first and second scrapers simply rotate during the same reciprocating stroke to scrape the unpacked powder into the metering mold. The unpacking powder is then pushed into the combined fireworks effect inner cylinder by the action of the unpacking assembly. Furthermore, a tensioned unpacking mechanism is employed during the unpacking process, with a rotating gate belt mounted on the gate. When the gate approaches the drive cylinder, the rotating gate belt rotates simultaneously, reducing friction and preventing localized heating that could ignite the unpacked powder and potentially cause safety hazards.

First, the drug enters the material box 53 through the feed pipe 54. The scraper assembly 57 scrapes the drug. During the scraping process, the laser sensor 56 can detect the thickness of the drug in the material box 53. The drug in the material box 53 needs to be maintained within a certain thickness range. Once the drug is insufficient or excessive, the drug mixing cylinder 4 can be controlled to discharge the drug faster or slower. The laser sensor 56 can ensure that the drug thickness is always maintained.

[0034] The scraper assembly 57 includes a stabilizing plate 5700, a guide rail 5701, a supporting cross plate 5702, a guide seat 5703, a guide rod 5704, a moving block 5705, a first rotating shaft 5706, a second rotating shaft 5707, a first scraper 5708, a second scraper 5709, a first hinge plate 5710, a second hinge plate 5711, a third hinge plate 5712, a limit block 5713 and a scraper cylinder 5714. Two stable plates 5700 are fixedly provided, and a guide rail 5701 is fixedly installed between the stable plates 5700, wherein one end of the two guide rails 5701 is fixedly connected to the supporting horizontal plate 5702, and a scraping cylinder 5714 is provided in the middle of the supporting horizontal plate 5702. The two guide rails 5701 are also movably equipped with a guide seat 5703, and the two sides of the guide seat 5703 are movably connected to the guide rod 5704, and the moving block 5705 is also movably installed on the guide rail 5701, and is located between the two stable plates 5700, wherein the moving blocks 5705 on both sides of the material box 53 are also connected by the first rotating shaft 5706 and the second rotating shaft 5707, and the first rotating shaft 5706 and the second rotating shaft 5707 are located in the slide groove 11, and the first rotating shaft 5706 and the second rotating shaft 5707 are fixedly installed with the first scraper 5708 and the second scraper 5709 respectively, and the first scraper 5708 and the second scraper 5709 are located inside the material box 53, and the two ends of the first rotating shaft 5706 are movably connected to the first hinge plate 5710, and the two ends of the second rotating shaft 5707 are movably connected to the third hinge plate 5712, and the second hinge plate 5711 is movably connected to the ends of the third hinge plate 5712 of the first hinge plate 5710 respectively, and the second hinge plate 5711 is also movably connected to the other end of the guide rod 5704, and the limit block 5713 is located on the outside of the moving block 5705.

[0035] The limiting block 5713 is in an inverted triangle structure and is located between the first rotating shaft 5706 and the second rotating shaft 5707 . The first hinge plate 5710 and the third hinge plate 5712 are respectively provided with anti-collision screws 12 .

[0036] Scraping principle:

[0037] First, the medicinal material enters the material box 53 through the feed pipe 54, driving the scraper cylinder 5714. The telescopic end of the scraper cylinder 5714 pushes the guide seat 5703 to move along the guide rail 5701. At this time, the guide rod 5704 pushes the second hinged plate 5711 to rotate the first rotating shaft 5706 and the second rotating shaft 5707. During the rotation, the first scraper 5708 moves from a vertical state to a horizontal state, and the second scraper 5709 moves from a vertical state to a horizontal state. The second scraper 5709 acts as a scraper, and as the moving block 5705 moves, the medicinal material will be scraped to the discharge port, so that the medicinal material falls into the quantitative mold 60. When reaching the leftmost end, the telescopic end of the scraper cylinder 5714 begins to retract. At this time, the second scraper 5709 is adjusted from vertical to horizontal, and the first scraper 5708 is adjusted from horizontal to vertical. During the pulling process, the first scraper 5708 acts as a scraper. The two ends of the bottom of the material box 53 are arc-shaped. In this way, when the first scraper 5708 and the second scraper 5709 rotate at the two ends inside the material box 53, the bottom of the first scraper 5708 and the second scraper 5709 are tangent to the material box 53. The purpose of setting the two ends of the material box 53 as arcs is to reduce drug accumulation. In this reciprocating process, the first scraper 5708 and the second scraper 5709 respectively achieve angle switching. At the same time, the flip angle of the first scraper 5708 and the second scraper 5709 can be controlled by adjusting the length of the anti-collision screw 12.

[0038] according to Figure 3 and Figure 6 The charge dispensing assembly 58 includes a discharge cylinder 5800, a guide post 5801, a discharge tray 5802, and a discharge rod 5803. The discharge cylinder 5800 is fixedly mounted on the top of the material box 53. The output end of the discharge cylinder 5800 is fixedly connected to the discharge tray 5802. Several discharge rods 5803 are installed at the bottom of the discharge tray 5802. Two guide posts 5801 are also fixed to the discharge tray 5802, and the guide posts 5801 partially extend through the top of the material box 53. When the metering mold 60 is filled, the discharge cylinder 5800 controls the discharge tray 5802 to move downward, causing the discharge rods 5803 to extend into the circular holes in the metering mold 60, thereby loading the charge into the firework effect inner cylinder.

[0039] Reference Figure 7-Figure 8The tensioning and unloading mechanism 6 includes a quantitative mold 60, a support plate 61, a gate 62, a connecting seat 63, a first belt fixing plate 64, a second belt fixing plate 65, a pre-tightening guide rod 66, a tensioning spring 67, a rotating gate belt 68, a diversion medicine hopper 69 and a driving cylinder 610. The quantitative mold 60 is fixedly installed at the unloading port of the material box 53. A plurality of circular holes are opened in the middle of the quantitative mold 60. The four corners of the quantitative mold 60 are fixedly connected to the support plate 61 through a connecting rod. One end of the support plate 61 is fixedly connected to the seat 63. The gate 62 is slidably installed on the support plate 61. The gate 62 is movable in the middle of the rotating gate belt 68. The support plate 61 is also opened. An installation groove is provided, and a diversion medicine hopper 69 is installed at the installation groove. The diversion medicine hopper 69 is located below the rotating gate belt 68. A driving cylinder 610 is also provided at one end of the connecting seat 63. The telescopic end of the driving cylinder 610 is fixedly connected to one end of the gate 62. A first belt fixing plate 64 is also fixedly provided on the connecting seat 63. The first belt fixing plate 64 is also connected to the second belt fixing plate 65 through a pre-tightening guide rod 66. A tensioning spring 67 is also provided on the pre-tightening guide rod 66, and the tensioning spring 67 is located at the outer end of the second belt fixing plate 65. The two ends of the rotating gate belt 68 are respectively fixedly connected to the first belt fixing plate 64 and the second belt fixing plate 65.

[0040] Principle of tensioning blanking mechanism:

[0041] In the initial state, the telescopic end of the driving cylinder 610 is in an extended state. At this time, the gate 62 is located directly below the quantitative mold 60. The diversion medicine hopper 69 is directly below the gate 62. The gate 62 and the rotating gate belt 68 are equivalent to a card plate, which separates the quantitative mold 60 and the diversion medicine hopper 69 from the middle. When unloading is required, the driving cylinder 610 is first driven to start working. The telescopic end of the driving cylinder 610 will drive the two ends of the gate 62 to move along the support plate 61. In this process, the gate 62 is pulled away from the middle of the quantitative mold 60 and the diversion medicine hopper 69. The gate 62 moves During the process, the rotating gate belt 68 is in a rotating state, because the first belt fixing plate 64 and the second belt fixing plate 65 are fixedly connected to the two ends of the rotating gate belt 68, and the first belt fixing plate 64 is fixedly installed on the connecting seat 63. In this way, as the gate 62 moves, the rotating gate belt mounted in the middle of the gate 62 will rotate. The setting of the rotating gate belt 68 can reduce friction while ensuring that the bottom of the powder will not collapse. In this way, under the action of the discharge rod 5803, the powder can be completely loaded into the combined fireworks effect inner tube.

[0042] Reference Figure 2 and Figure 10, the effect inner tube conveying mechanism 7 includes an effect inner tube conveying belt 70, an effect inner tube support seat 71, a clamping cylinder 72, a clamping plate 73, a clamping claw 74 and a tensioning shaft 75. The support frame 1 is also provided with an effect inner tube conveying belt 70, and an effect inner tube support seat 71 and a tensioning shaft 75 are arranged inside the effect inner tube conveying belt 70. The effect inner tube support seat 71 and the tensioning shaft 75 are both installed on the support frame 1. The effect inner tube support seat 71 ensures a stable working surface during the loading process. A clamping cylinder 72 is also fixedly installed inside the tube support seat 71. Both sides of the clamping cylinder 72 are fixedly connected to the clamping plates 73. The upper part of the clamping plates 73 is also fixedly connected to the clamping claws 74. When the firework effect inner tube passes through the effect inner tube conveyor belt 70 and reaches the effect inner tube support seat 71, the clamping cylinder 72 will make the clamping plates 73 on both sides close together, and the clamping plates 73 will make the clamping claws 74 fix and clamp the firework effect inner tube, which is convenient for loading. The bottom of the clamping claws 74 is in contact with the upper surface of the effect inner tube conveyor belt 70.
