Description

Technical Field

[0001] The invention relates to the technical field of fireworks product processing equipment, and in particular to automatic tube-forming equipment and technology for double-shot fireworks. Background Art

[0002] Fireworks, also known as fireworks, fireworks, firecrackers, are entertainment products that use pyrotechnic powder as raw materials to produce sound, light and color. When processing double-shot fireworks, it is necessary to punch holes in the paper tube, insert the lead, fill the clay material, press the clay and arrange the tube. In order to ensure the safe production of fireworks, existing fireworks usually use manual tube arrangement, but manual processing is inefficient and cannot maintain stable processing quality for a long time.

[0003] To this end, Chinese patent CN107421399B discloses a tube-forming device for a double-shot fireworks automatic forming machine, which has a rotating disk and a lifting disk arranged on the upper end of the rotating disk. Several tube-forming rods are arranged and combined on the rotating disk and penetrate the lifting disk. When the tubes are discharged, the lifting disk rotates and moves horizontally with the rotating disk and inserts the tubes one by one into the tube-forming rods arranged and combined with the cooperation of the robot tube-taking device of the double-shot fireworks automatic forming machine. After the tubes are formed, the tube-forming and extracting mechanism located on one side of the rotating disk and the lifting disk rotates to the top thereof. The lifting plate rises to push the arranged and formed cylinder combination out of the cylinder rod, and is clamped by the clamping part of the cylinder forming and extracting mechanism and then rotated out of the cylinder forming station to the lifting platform. It realizes the automatic mechanical cylinder forming process of double-shot fireworks cylinders after punching, inserting, clay filling, clay pressing and cylinder taking. It has a fast cylinder forming speed, improves production efficiency, reduces labor use, and effectively reduces production costs. The cylinder rod can be configured on the rotating plate according to the arrangement and combination corresponding to actual needs, so that the formed cylinders can be combined into different specifications and shapes.

Detailed implementation manners

[0031] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0032] Refer to Figures 1-5:A double - sound fireworks automatic row - cylinder forming device, comprising a feeding device 1 and a row - cylinder device 2; the feeding device 1 includes a guide rail 11 and a baffle 12; the guide rail 11 is inclined downward from top to bottom and the included angle between its extending direction and the horizontal plane is an acute angle, and a notch 111 is opened at the end of the guide rail 11; the baffle 12 is installed on the guide rail 11 and is located at the end of the guide rail 11, the row - cylinder device 2 includes a support frame 21, a buckle 22 and a connecting rod 23; there are two support frames 21, the buckle 22 and the connecting rod 23 are respectively installed on the two support frames 21, and the connecting rod 23 is in sliding fit with the buckle 22; a fixing device 3 is arranged on the support frame 21, the fixing device 3 includes a conical cylinder 31 and a first elastic member 32; there are at least two conical cylinders 31, the plurality of conical cylinders 31 are evenly divided into two groups, and the two groups of conical cylinders 31 are respectively slidably arranged on the two support frames 21; a fixing ring 311 is arranged on the conical cylinder 31, and the two ends of the first elastic member 32 are respectively connected with the fixing ring 311 and the support frame 21; an auxiliary control device 4 is arranged on the support frame 21, the auxiliary control device 4 includes a first locking assembly 41 and a first control assembly 42; the first locking assembly 41 is installed on the support frame 21 and is used to limit the sliding of the conical cylinder 31; the first control assembly 42 is arranged on the support frame 21 and is used to control the opening and closing of the first locking assembly 41.

[0033] The present invention realizes the function of discharging cylinders directly without grasping the paper cylinder 6 through the feeding device 1, the cylinder discharging device 2, the fixing device 3 and the auxiliary control device 4, achieving the effect of continuous and stable cylinder discharging, and solving the problem that the existing cylinder forming equipment relies on a manipulator to grasp the paper cylinder 6, resulting in the paper cylinder 6 being extremely vulnerable to damage. A plurality of conical cylinders 31 are distributed at equal intervals in a matrix on the support frame 21. Two support rods 211 are installed on each support frame 21. The support frame 21 is connected to the hydraulic driving rod through the support rods 211, and the hydraulic driving rod is not shown in the figure. Two support frames 21 and two operators respectively place the paper cylinder 6 on the guide rail 11. The guide rail 11 is inclined. The paper cylinder 6 is cylindrical, so that the paper cylinder 6 rolls to the notch 111 under the action of gravity and is blocked by the baffle 12. As the paper cylinder 6 is continuously supplied, it is arranged in an array along the guide rail 11. Then, the hydraulic driving rod drives the support frame 21 to move to the notch 111 at the end of the guide rail 11, so that the conical cylinder 31 is aligned with the paper cylinder 6 at the notch 111. Then, the first control component 42 releases the movement restriction of the first locking component 41 on the conical cylinder 31. The first elastic member 32 pushes the fixing ring 311, and drives the conical cylinder 31 to move towards the paper cylinder 6 through the fixing ring 311, thereby fixing the paper cylinder 6 through the two conical cylinders 31, and completing the cylinder discharging of a single paper cylinder 6. Then, the hydraulic driving rod pushes the support rod 211 to move upward. The support rod 211 drives the support frame 21 to move. The support frame 21 drives the conical cylinder 31 and the paper cylinder 6 to move, and takes out the paper cylinder 6 from the guide rail 11 at the notch 111. The paper cylinders 6 arranged on the guide rail 11 slide downward along the guide rail 11, so that the upper paper cylinder 6 moves to the baffle 12, facilitating the subsequent cylinder discharging. Repeat the above actions to fix the paper cylinder 6 between the two support frames 21.

[0034] Refer to Figure 1 , Figures 3-5 : The fixing device 3 further includes a nitrogen spring 33; the nitrogen spring 33 is installed on the conical cylinder 31, and a docking rod 331 is slidably installed on the nitrogen spring 33. The piston in the nitrogen spring 33 is connected to the docking rod 331; a through hole extending along the axial direction is provided on the conical cylinder 31, and the docking rod 331 is slidably matched with the through hole; the auxiliary control device 4 further includes a second locking component 43 and a second control component 44; the second locking component 43 is arranged on the conical cylinder 31 and is used to fix the docking rod 331; the second control component 44 is arranged on the support frame 21 and is used to control the opening and closing of the second locking component 43.

[0035] The present invention realizes the function of further supporting the paper tube 6 through the nitrogen spring 33, the second locking component 43 and the second control component 44, achieving the effect of supporting the paper tube 6 only through the cooperation of the single-side support frame 21 and the docking rod 331, and further realizing the purpose of facilitating the subsequent processing of the paper tube 6 after the tube discharging is completed. A support 35 is installed on the support frame 21, and the support 35 is connected to the nitrogen spring 33. Since the nitrogen spring 33 is relatively long, the support 35 can support the nitrogen spring 33 to improve the structural stability. When discharging the tubes, the operator first drives the support frame 21 to move to the notch 111 at the end of the guide rail 11 through the hydraulic drive rod, so that the tapered cylinder 31 is aligned with the paper tube 6 at the notch 111. Then, the operator releases the movement restriction of the first locking component 41 on the tapered cylinder 31 through the first control component 42. The first elastic member 32 pushes the fixing ring 311, and drives the tapered cylinder 31 to move towards the paper tube 6 through the fixing ring 311, and then fixes the paper tube 6 through the two tapered cylinders 31. Then, the operator releases the movement restriction of the second locking component 43 on the docking rod 331 through the second control component 44. The docking rod 331 extends under the elastic force of the nitrogen spring 33 and is inserted into the paper tube 6. After moving the paper tube 6 to the subsequent processing position, the operator controls the support frame 21 without the docking rod 331 to move away from the paper tube 6 through the hydraulic drive rod, and supports the paper tube 6 through the docking rod 331 on the single-side support frame 21. The operator can also control the rotation of the support frame 21 through the hydraulic drive rod, so that the paper tube 6 can be vertically arranged, which facilitates the subsequent processing actions. After the processing is completed, the paper tube 6 is removed from the support frame 21. Then, the operator controls the two support frames 21 to approach each other through the hydraulic drive rod. The tapered cylinder 31 and the docking rod 331 are reset by the mutual extrusion of the two tapered cylinders 31, and the tapered cylinder 31 and the docking rod 331 are fixed by the first locking component 41 and the second locking component 43 respectively, so as to facilitate the subsequent tube discharging action.

[0036] Refer to Figure 1 , Figure 3 and Figure 8 : A positioning component 34 is provided on the tapered cylinder 31. The positioning component 34 includes a mounting rod 341 and a distance sensor 342; the mounting rod 341 is mounted on the tapered cylinder 31 and its axis is collinear with the axis of the tapered cylinder 31; the distance sensor 342 is mounted on the mounting rod 341.

[0037] The present invention realizes the function of detecting the axis deviation error between the conical tube 31 and the paper tube 6 by installing the rod 341 and the distance sensor 342, thereby achieving the effect of improving the displacement accuracy of the conical tube 31. The distance sensor 342 is electrically connected to the controller; when arranging the tubes, the operator first drives the support frame 21 to move to the notch 111 at the end of the guide rail 11 through the hydraulic drive rod, so that the conical tube 31 is aligned with the paper tube 6 at the notch 111, and then the distance sensor 342 is used to detect the distance between the two conical tubes 31. If the deviation between the axis of the conical tube 31 and the axis of the paper tube 6 is large, the light signal emitted by the distance sensor 342 is blocked by the paper tube 6, and the detected distance is shorter; if the deviation between the axis of the conical tube 31 and the axis of the paper tube 6 is small, the light signal emitted by the distance sensor 342 can pass through the paper tube 6 and illuminate the docking rod 331 on the conical tube 31 at the corresponding position on the other support frame 21; the distance sensor 342 feeds back a signal to the controller, and the controller can determine the alignment of the conical tube 31 and the paper tube 6 based on the feedback data. If the deviation is small, the tube arranging action continues; if the deviation is large, the tube arranging is stopped and the operator is left to solve the problem. After the conical tube 31 is aligned with the paper tube 6, the first control assembly 42 releases the movement restriction of the conical tube 31 by the first locking assembly 41, and the first elastic member 32 pushes the fixing ring 311, and drives the conical tube 31 to move toward the direction close to the paper tube 6 through the fixing ring 311, and then fixes the paper tube 6 through the two conical tubes 31. Then, the second control assembly 44 releases the movement restriction of the docking rod 331 by the second locking assembly 43, and the docking rod 331 extends under the elastic force of the nitrogen spring 33 and is inserted into the paper tube 6 to further support the paper tube 6. After the processing is completed, the paper tube 6 is removed from the support frame 21, and then the two support frames 21 are controlled to approach each other by the hydraulic drive rod, and the conical tube 31 and the docking rod 331 are reset by the mutual squeezing of the two conical tubes 31, and the conical tube 31 and the docking rod 331 are respectively fixed by the first locking assembly 41 and the second locking assembly 43, so as to facilitate the subsequent tube discharging action.

[0038] Reference Figures 4-6 : The first locking assembly 41 includes a mounting ring 411, a first locking block 412, a first control plate 413 and a second elastic member 414; the mounting ring 411 is mounted on the support frame 21; the first locking block 412 and the first control plate 413 are slidably mounted on the mounting ring 411, and a locking groove 415 cooperating with the first locking block 412 is provided on the conical cylinder 31; the first control plate 413 is transmission-connected to the first control assembly 42; the two ends of the second elastic member 414 are respectively connected to the first locking block 412 and the first control plate 413.

[0039] The present invention realizes the function of restricting the movement of the conical cylinder 31 through the mounting ring 411, the first locking block 412, the first control piece 413, the second elastic member 414 and the locking groove 415. When discharging the cylinders, the operator first drives the support frame 21 to move to the notch 111 at the end of the guide rail 11 through the hydraulic drive rod, so that the conical cylinder 31 is aligned with the paper cylinder 6 at the notch 111. Then, the distance sensor 342 is used to detect the distance between the two conical cylinders 31 and feed back a signal to the controller. After the conical cylinder 31 is aligned with the paper cylinder 6, the first control assembly 42 drives the first control piece 413 to move away from the locking groove 415. The first control piece 413 drives the first locking block 412 to move through the second elastic member 414, so that the first locking block 412 is separated from the locking groove 415, and the movement restriction of the first locking assembly 41 on the conical cylinder 31 is released. The first elastic member 32 pushes the fixing ring 311, and drives the conical cylinder 31 to move towards the paper cylinder 6 through the fixing ring 311, so as to fix the paper cylinder 6 through the two conical cylinders 31. Then, the second control assembly 44 releases the movement restriction of the second locking assembly 43 on the docking rod 331. The docking rod 331 extends under the elastic force of the nitrogen spring 33 and is inserted into the paper cylinder 6 to further support the paper cylinder 6.

[0040] Refer to Figures 4-6 : The first control assembly 42 includes a third elastic member 421, a first rack 422, a transmission roller 423 and a second rack 424; both ends of the third elastic member 421 are respectively connected to the first control piece 413 and the support frame 21; the first rack 422 is slidably mounted on the mounting ring 411 and is connected to the first control piece 413; the transmission roller 423 is rotatably mounted on the mounting ring 411, and the transmission roller 423 is connected to the first rack 422 and the second rack 424; the second rack 424 is slidably mounted on the mounting ring 411; a driving device 5 is further provided on the support frame 21, and the driving device 5 includes a first linear driving assembly 51, and the first linear driving assembly 51 is mounted on the support frame 21 and is used to drive the second rack 424 to move.

[0041] The present invention realizes the function of controlling the opening and closing of the first locking assembly 41 through the third elastic member 421, the first rack 422, the transmission roller 423, the second rack 424 and the first linear drive assembly 51. The first linear drive assembly 51 is electrically connected to the controller; when arranging tubes, the operator first drives the support frame 21 to move to the notch 111 at the end of the guide rail 11 through the hydraulic drive rod, so that the conical tube 31 is aligned with the paper tube 6 at the notch 111, and then detects the distance between the two conical tubes 31 through the distance sensor 342, and feeds back the signal to the controller. After the conical tube 31 is aligned with the paper tube 6, the controller sends a signal to the first linear drive assembly 51, and the first linear drive assembly 51 drives the second rack 424 to move, and the second rack 424 drives the transmission roller 423 to rotate. The first rack 422 is driven to move through the transmission roller 423, and the elastic force of the third elastic member 421 is overcome to drive the first rack 422 to move in the direction away from the locking groove 415. The first control piece 413 drives the first locking block 412 to move through the second elastic member 414, so that the first locking block 412 is separated from the locking groove 415, and the movement restriction of the conical tube 31 by the first locking assembly 41 is released. The first elastic member 32 pushes the fixing ring 311, and drives the conical tube 31 to move in the direction close to the paper tube 6 through the fixing ring 311, and then fixes the paper tube 6 through the two conical tubes 31. Then, the movement restriction of the docking rod 331 by the second locking assembly 43 is released through the second control assembly 44, and the docking rod 331 extends out under the elastic force of the nitrogen spring 33, and is inserted into the paper tube 6 to further support the paper tube 6.

[0042] Reference Figures 4-9 : The second locking assembly 43 includes a mounting seat 431, a second locking block 432, a second control plate 433 and a fourth elastic member 434; the mounting seat 431 is mounted on the conical cylinder 31; the second locking block 432 and the second control plate 433 are slidably mounted on the mounting seat 431, and the second control plate 433 is transmission-connected with the second control assembly 44; the two ends of the fourth elastic member 434 are respectively connected to the second locking block 432 and the second control plate 433; an annular groove 435 is provided on the docking rod 331.

[0043] The present invention realizes the function of restricting the movement of the docking rod 331 through the mounting seat 431, the second locking block 432, the second control piece 433, the fourth elastic member 434, and the annular groove 435. When discharging the paper tubes, the operator first drives the support frame 21 to move to the notch 111 at the end of the guide rail 11 through the hydraulic drive rod, so that the tapered tube 31 is aligned with the paper tube 6 at the notch 111. Then, the distance sensor 342 is used to detect the distance between the two tapered tubes 31 and feed back the signal to the controller. After the tapered tube 31 is aligned with the paper tube 6, the controller sends a signal to the first linear drive assembly 51. The first linear drive assembly 51 drives the second rack 424 to move. The second rack 424 drives the transmission roller 423 to rotate and drives the first rack 422 to move through the transmission roller 423, overcoming the elastic force of the third elastic member 421 to drive the first rack 422 to move away from the locking groove 415. The first control piece 413 drives the first locking block 412 to move through the second elastic member 414, so that the first locking block 412 is separated from the locking groove 415, releasing the movement restriction of the first locking assembly 41 on the tapered tube 31. The first elastic member 32 pushes the fixing ring 311 and drives the tapered tube 31 to move towards the paper tube 6 through the fixing ring 311, thereby fixing the paper tube 6 through the two tapered tubes 31. Then, the second control assembly 44 is used to drive the second control piece 433 to slide away from the annular groove 435. The second control piece 433 drives the second locking block 432 to move through the fourth elastic member 434, so that the second locking block 432 is separated from the annular groove 435, releasing the movement restriction of the second locking assembly 43 on the docking rod 331. The docking rod 331 extends under the elastic force of the nitrogen spring 33 and is inserted into the paper tube 6 to further support the paper tube 6. After the processing is completed, the paper tube 6 is removed from the support frame 21. Then, the two support frames 21 are controlled to approach each other through the hydraulic drive rod. The tapered tube 31 and the docking rod 331 are reset by the mutual extrusion of the two tapered tubes 31. When the locking groove 415 on the tapered tube 31 is aligned with the first locking block 412, the first locking block 412 is snapped into the locking groove 415 under the elastic force of the second elastic member 414. When the second locking block 432 is aligned with the annular groove 435, it is snapped into the annular groove 435 under the elastic force of the fourth elastic member 434, thereby fixing the tapered tube 31 and the docking rod 331 respectively through the first locking assembly 41 and the second locking assembly 43 to facilitate the subsequent paper tube discharging operation.

[0044] Refer to Figures 4-9 : The second control assembly 44 includes a fifth elastic member 441 and an extension rod 442; both ends of the fifth elastic member 441 are respectively connected to the second control piece 433 and the mounting seat 431; the extension rod 442 is installed on the second control piece 433; a second linear drive assembly 52 for driving the extension rod 442 to move is installed on the support frame 21.

[0045] The present invention realizes the function of controlling the opening and closing of the second locking assembly 43 through the fifth elastic member 441, the extension rod 442 and the second linear drive assembly 52. The second linear drive assembly 52 is electrically connected to the controller; when arranging the tubes, the operator first drives the support frame 21 to move to the notch 111 at the end of the guide rail 11 through the hydraulic drive rod, so that the conical tube 31 is aligned with the paper tube 6 at the notch 111, and then detects the distance between the two conical tubes 31 through the distance sensor 342, and feeds back the signal to the controller. After the conical tube 31 is aligned with the paper tube 6, the controller sends a signal to the first linear drive assembly 51, and the first linear drive assembly 51 drives the second rack 424 to move, and the second rack 424 drives the transmission roller 423 to rotate. The first rack 422 is driven to move through the transmission roller 423, overcoming the elastic force of the third elastic member 421 to drive the first rack 422 to move in the direction away from the locking groove 415, and the first control plate 413 drives the first locking block 412 to move through the second elastic member 414, so that the first locking block 412 is separated from the locking groove 415, and the movement restriction of the conical tube 31 by the first locking assembly 41 is released. The first elastic member 32 pushes the fixing ring 311, and drives the conical tube 31 to move in the direction close to the paper tube 6 through the fixing ring 311, and then fixes the paper tube 6 through the two conical tubes 31. Then, a signal is sent to the second linear drive component 52 through the controller, and the second linear drive component 52 drives the extension rod 442 to move in the direction away from the annular groove 435, overcoming the elastic force of the fifth elastic member 441 to drive the second control plate 433 to slide, and the second control plate 433 drives the second locking block 432 to move through the fourth elastic member 434, thereby separating the second locking block 432 from the annular groove 435, releasing the movement restriction of the docking rod 331 by the second locking component 43, and the docking rod 331 extends out under the elastic force of the nitrogen spring 33, and is inserted into the paper tube 6 to support the paper tube 6.

[0046] Reference Figure 1 , Figure 3 and Figure 10 : The first linear drive component 51 includes a first screw 511, a first slider 512, a first push block 513, a fixed block 514 and a first rotation driver 515; the first screw 511 is rotatably mounted on the support frame 21; the first slider 512 is slidably mounted on the support frame 21 and is threadedly connected to the first screw 511; the first push block 513 is arranged on the first slider 512, and the first push block 513 is provided with an inclined surface 5131; the fixed block 514 is arranged on the second rack 424 and is provided with an arc surface 5141; the first rotation driver 515 is installed on the support frame 21 and its driving end is transmission-connected to the first screw 511.

[0047] The present invention realizes the function of driving the first control plate 413 to move through the first screw 511, the first slider 512, the first push block 513, the fixed block 514 and the first rotary driver 515. The first rotary driver 515 is preferably a servo motor, which is electrically connected to the controller. When arranging tubes, the operator first drives the support frame 21 to move to the notch 111 at the end of the guide rail 11 through the hydraulic drive rod, so that the conical tube 31 is aligned with the paper tube 6 at the notch 111, and then detects the distance between the two conical tubes 31 through the distance sensor 342, and feeds back the signal to the controller. After the conical tube 31 is aligned with the paper tube 6, the controller sends a signal to the first rotary driver 515. After receiving the signal, the first rotary driver 515 drives the first screw 511 to rotate, and the first screw 511 drives the first slider 512 threadedly connected thereto to move, and the first slider 512 drives the first push block 513 to move. When the inclined surface 5131 of the first push block 513 is aligned with the fixed block 514, the first push block 513 moves. After the arc surface 5141 of the fixed block 514 contacts, it squeezes the fixed block 514, and then drives the second rack 424 to move through the fixed block 514, the second rack 424 drives the transmission roller 423 to rotate and drives the first rack 422 to move through the transmission roller 423, overcomes the elastic force of the third elastic member 421 to drive the first rack 422 to move in the direction away from the locking groove 415, the first control plate 413 drives the first locking block 412 to move through the second elastic member 414, so that the first locking block 412 is separated from the locking groove 415, and the movement restriction of the conical tube 31 by the first locking assembly 41 is released, the first elastic member 32 pushes the fixing ring 311, and drives the conical tube 31 to move in the direction close to the paper tube 6 through the fixing ring 311, and then fixes the paper tube 6 through the two conical tubes 31. Then, the second control component 44 releases the movement restriction of the docking rod 331 by the second locking component 43 , and the docking rod 331 extends out under the elastic force of the nitrogen spring 33 and is inserted into the paper tube 6 to further support the paper tube 6 .

[0048] Reference Figure 1 , Figure 3 and Figure 10 : The second linear drive assembly 52 includes a second screw 521, a second slider 522, a second push block 523 and a second rotation driver 524; the second screw 521 is rotatably mounted on the support frame 21; the second slider 522 is slidably mounted on the support frame 21 and is threadedly connected to the second screw 521; the second push block 523 is disposed on the second slider 522; the second rotation driver 524 is mounted on the support frame 21 and its driving end is transmission-connected to the second screw 521.

[0049] The present invention realizes the function of driving the second control piece 433 to move through the second screw rod 521, the second slider 522, the second push block 523 and the second rotary driver 524. The second rotary driver 524 is preferably a servo motor, and the servo motor is electrically connected to the controller. A first limit block 5121 and a second limit block 5221 are respectively installed on the first slider 512 and the second slider 522; when discharging the cylinders, the operator first drives the support frame 21 to move to the notch 111 at the end of the guide rail 11 through the hydraulic drive rod, so that the conical cylinder 31 is aligned with the paper cylinder 6 at the notch 111. Then, the movement restriction of the conical cylinder 31 by the first locking assembly 41 is released. The first elastic member 32 pushes the fixing ring 311, and drives the conical cylinder 31 to move towards the paper cylinder 6 through the fixing ring 311, thereby fixing the paper cylinder 6 by the two conical cylinders 31. Then, the controller sends a signal to the second rotary driver 524. After receiving the signal, the second rotary driver 524 drives the second screw rod 521 to rotate. The second screw rod 521 drives the second slider 522 that is threadedly connected thereto to move. The second slider 522 drives the second push block 523 to move. When the second push block 523 contacts the extension rod 442, it squeezes the extension rod 442, and then drives the second control piece 433 to slide away from the annular groove 435 through the extension rod 442. The second control piece 433 drives the second locking block 432 to move through the fourth elastic member 434, so that the second locking block 432 is separated from the annular groove 435, and the movement restriction of the docking rod 331 by the second locking assembly 43 is released. The docking rod 331 extends out under the elastic force of the nitrogen spring 33 and is inserted into the paper cylinder 6 to further support the paper cylinder 6. And through the cooperation of the first limit block 5121 and the second limit block 5221, at the initial position, the first limit block 5121 contacts the second slider 522 and restricts the movement of the second slider 522. When the first slider 512 moves towards the fixed block 514, the second slider 522 can move. And when the second slider 522 moves to the fixed block 514 and the conical cylinder 31 extends out, the controller sends a signal to the second rotary driver 524, achieving the purpose of extending the docking rod 331 only after the paper cylinder 6 is fixed, and avoiding the premature extension of the docking rod 331 when the conical cylinder 31 has not extended out.

[0050] Refer to Figures 1-5 : A double - bang fireworks automatic cylinder - discharging and forming process, comprising the following steps: S1. Align the conical cylinder 31 with the paper cylinder 6; S2. Release the movement restriction of the conical cylinder 31 by the first locking assembly 41 through the first control assembly 42; S3.
