[0052] Please refer to Figures 1-8 , the torque adjustment mechanism 4 for batch rotation of fireworks and firecrackers in the present invention includes:

[0053] An adjustment station 41, on both sides of the adjustment station 41, guide rails 42 are provided along the X-axis, and one end of the guide rail 42 is the feeding side;

[0054] A docking member 43, the docking member 43 is used to dock the fireworks and firecrackers 6 conveyed in the X-axis direction. The docking member 43 includes a sliding block 431 slidably connected to the two guide rails 42, and a docking plate 432 rotatably installed between the two sliding blocks 431. The docking plate 432 is rotatably connected to the sliding block 431; the docking plate 432 is used to temporarily store the fireworks and firecrackers 6;

[0055] A plurality of mounting holes are provided on the docking plate 432, and docking pipes 433 for temporarily storing the fireworks and firecrackers 6 are installed in the mounting holes. The docking pipes 433 on the plurality of docking plates 432 are all arranged along the feeding side in the X-axis direction; a docking hole 4331 with a diameter larger than that of the fireworks and firecrackers 6 is provided inside the docking pipe 433, and an elastic limiting member for restricting the fireworks and firecrackers 6 from being temporarily stored in the docking hole 4331 is provided inside the docking hole 4331;

[0056] An adjustment assembly 44, which is used to adjust the distance between the docking members 43 and drive the docking plate 432 to rotate the temporarily stored horizontal fireworks and firecrackers 6 to the vertical direction facing the fireworks mold 5.

[0057] The adjustment assembly 44 includes an adjustment member 441 for changing the distance between the docking plates 432, and a rotation member 442 for rotating the docking plate 432 after the distance is changed.

[0058] The adjustment member 441 includes a limiting unit 4411 and a first power member 4412; the limiting unit 4411 is used to limit the distance between the docking members 43; the first power member 4412 is used to drive the docking members 43 and generate different distances under the limitation of the limiting unit 4411.

[0059] The limiting unit 4411 includes a plurality of limiting plates 44111 and limiting rods 44114. Limiting holes 44112 are defined at both ends of the limiting plates 44111. The limiting holes 44112 of the limiting plates 44111 are interconnected when the limiting plates 44111 are interleaved and overlapped. Limiting pins 44113 are inserted into the overlapping limiting holes 44112 and the non-overlapping limiting holes 44112. The limiting pins 44113 are slidable in the limiting holes 44112.

[0060] The limiting bolt 44113 carries the limiting plate 44111 which are fixedly mounted on the sliding block 431 in one-to-one correspondence. The limiting plate 44111 can slide on the surface of the sliding block 431 and the limiting bolt 44113 . The limiting rod 44114 is mounted on the docking plate 432 in parallel with the docking tube 433 .

[0061] The rotating component 442 includes a plurality of rotating rods 4421 and a driving unit 4423 for driving the rotating rods 4421 to rotate synchronously; the rotating rods 4421 and the docking plates 432 are arranged in a one-to-one correspondence, and the rotating rods 4421 and the docking plates 432 are connected by a telescopic universal joint 4422.

[0062] The driving unit 4423 includes a movable rod 44231 and a second power member 44232 for moving the movable rod 44231. The second power member 44232 is connected to the end of the movable rod 44231 via a cylinder universal joint 44233. The movable rod 44231 is equipped with a swing arm 44234 corresponding to each of the rotating rods 4421. The swing arm 44234 rotates to drive the rotating rod 4421.

[0063] It also includes a loading mechanism 2, which is installed along the X-axis and is used for batch temporary storage of horizontal fireworks and firecrackers 6, and can batch-shift the temporarily stored batches of fireworks and firecrackers 6 to the adjustment station 41. The loading mechanism 2 includes a waiting rail 201 and a shifting unit 202 for shifting the fireworks and firecrackers 6 on the waiting rail 201 to the adjustment station 41, and the tail end of the waiting rail 201 is arranged in a one-to-one correspondence with the docking tube 433 on the docking plate 432.

[0064] Working principle:

[0065] S1. When enough fireworks and firecrackers 6 are located in the waiting rail 201 of the feeding mechanism 2 on the X axis, the toggle unit 202 in the feeding mechanism 2 is activated. The activation of the toggle unit 202 can make the fireworks and firecrackers 6 located in the waiting rail 201 slide along the X direction. Because the tail end of the waiting rail 201 is arranged in a one-to-one correspondence with the docking tube 433 on the docking plate 432, and the docking tube 433 is initially arranged along the X axis, the fireworks and firecrackers 6 located in the waiting rail 201 will enter the docking hole 4331 of the docking tube 433 under the drive of the toggle unit 202. After the thrust of the toggle unit 202 is lost, the fireworks and firecrackers 6 are stuck in the docking hole 4331 through the elastic limiter in the docking hole 4331.

[0066] S2. The adjusting member 441 in the adjusting assembly 44 is activated to expand the distance between each docking member 43, thereby adjusting the gap between each fireworks 6 for subsequent rotation from the X-axis to the vertical state, thereby avoiding interference when the fireworks 6 rotate;

[0067] S2.1. The first power member 4412 in the adjustment component 441 is activated to cause the sliding block 431 in the docking member 43 at the rear end to slide on the guide rail 42. Due to the arrangement of the limiting unit 4411, when the sliding block 431 at the rear end slides, it pulls the limiting plate 44111 via the limiting bolt 44113. The limiting bolt 44113 then slides in the limiting plate 44111 to the end of the limiting hole 44112, thereby increasing the distance between the sliding blocks 431.

[0068] S3, the rotating component 442 in the adjustment assembly 44 is started, which can drive the docking member 43 and the firework 6 to rotate from the X-axis to the vertical state;

[0069] S3.1. The second power member 44232 in the rotating component 442 is activated, causing the movable rod 44231 to synchronously drive all the rotating rods 4421 to rotate via the swing arm 44234. Since the rotating rods 4421 are connected to the docking plate 432 in the docking member 43 via the telescopic universal joint 4422, when the rotating rods 4421 rotate, the docking plate 432 rotates 90 degrees on the sliding block 431, thereby rotating the firework 6 from the X-axis to the vertical position.

[0070] S4. The first power member 4412 of the adjusting component 441 is activated again, causing the sliding block 431 and the docking plate 432 to slide along the X-axis and gather on one side. This allows the vertical spacing of the fireworks 6 to match the spacing between the holes in the fireworks mold 5, making it easier for the subsequent loading mechanism 3 to push the fireworks 6 located in the docking tube 433 into the fireworks mold 5.

[0071] In this step, the vertical position of the fireworks 6 is limited by the width of the docking plate 432;

[0072] S4. After the fireworks 6 on the docking plate 432 are loaded, the docking plate 432 is reversely reset through steps S4, S3, and S2 in sequence. During the reset in step S2, since the first power member 4412 is started in S2.1 to expand the distance between each docking member 43, the docking members 43 need to be closed in this step. When closing, the limit rod 44114 on the docking plate 432 is pressed against the other docking plate 432 to control the closing range and ensure the reset effect.

[0073] In summary, the above-mentioned mechanism can adjust the fireworks and firecrackers 6 from a horizontal state to a vertical state in batches at one time without affecting the subsequent loading process. Moreover, the device can use the loading mechanism 2 to move the fireworks and firecrackers 6 of the previous process in batches to all the docking parts 43 at one time, so that the fireworks and firecrackers 6 can be flipped over without waiting, thereby improving the production rhythm.

[0074] Specifically, the butt joint tube 433 includes a fixing ring 4333, on the upper half of one side of the fixing ring 4333, a pawl 4332 is intermittently fixedly installed, and the lower half of the fixing ring 4333 and the pawl 4332 on the same side extends horizontally outward to form an arc-shaped support plate 4334, and a butt joint hole 4331 is formed between the interior of the arc-shaped support plate 4334 and the pawl 4332. The pawl 4332 is inclined toward the axis of the butt joint hole 4331 to form an elastic limiter. The structure is simple and can limit the fireworks 6 while facilitating the passage of the fireworks 6 in the X-axis direction.

[0075] Specifically, the butt joint tube 433 includes a fixing ring 4333, and a ratchet 4332 is intermittently fixed around one side of the fixing ring 4333. The ratchet 4332 is inclined toward the axis of the butt joint hole 4331 to form an elastic limiter. The ends of the ratchet 4332 form a hole with a diameter smaller than the firework 6.

[0076] Specifically, the other end of the fixing ring 4333 away from the pawl 4332 is also fixedly connected to a conical guide ring 4335, and the conical guide ring 4335 expands toward the side away from the pawl 4332 to facilitate docking with the fireworks 6.

[0077] Specifically, the waiting rail 201 in the loading mechanism 2 is provided with a waiting slot 2011 corresponding to the docking hole 4331, and an adjustment hole 2012 is provided on the waiting slot 2011 along the conveying rail track;

[0078] The loading mechanism 2 also includes a loading tooth plate 2021 for pushing the fireworks and firecrackers 6 in the waiting area out at one time, a third power member 2022 for controlling the loading tooth plate 2021 to extend into the waiting slot 2011 through the adjustment hole 2012, and a fourth power member 2023 for carrying the second power member 44232 and the loading tooth plate 2021 to slide in the adjustment hole 2012.

[0079] During use, the feeding tooth plate 2021 is inserted into the adjustment hole 2012 of the waiting rail 201 by the third power member 2022, and then the feeding tooth plate 2021 drives the fireworks 6 to slide in the waiting rail 201 into the docking pipe 433 of the docking member 43 through the fourth power member 2023, so as to realize one-time batch feeding into the docking pipe 433.

[0080] Among them, the feeding mechanism 2 in this embodiment can be modified as long as it can feed all the docking plates 432 in the X-axis direction at one time;

[0081] Among them, the first power member 4412, the second power member 44232, the third power member 2022, and the fourth power member 2023 all play a role in linear driving in this embodiment. Preferably, they are structures such as electric poles and cylinders. Of course, other mechanisms capable of linear driving should also be within the protection scope.

[0082] Among them, the loading mechanism 3 is at least a thimble that reciprocates up and down from top to bottom, and the thimble is used to push the fireworks 6 into the fireworks mold 5;

[0083] Among them, the fireworks 6 and the fireworks mold 5 can be referred to as the inner tube of the fireworks and the fireworks mass in the fireworks field.

[0084] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
