Description

Technical Field

[0001] This invention belongs to the field of fireworks processing technology, specifically an automatic loading and unloading device for fireworks processing. Background Technology

[0002] Firework tube cakes are an important intermediate product in the production of combination fireworks. They are usually made by tightly arranging dozens or even hundreds of firework paper tubes in a hexagonal pattern and binding them tightly to form a regular hexagonal tube cake. In subsequent processing steps such as adding firework powder and sealing the bottom, the binding rings on the outside of the tube cake need to be removed (i.e., "removing the binding rings"), and the loosened firework paper tubes need to be sorted and transported to the next work station in sequence (i.e., "tube sorting").

[0003] Currently, the unbinding and tube sorting operations in fireworks production enterprises generally rely on manual labor. Workers need to manually cut or untie the binding rings around the tubes, then straighten the loose paper tubes one by one and place them at the loading station. This method of operation has many shortcomings: on the one hand, manual unbinding is inefficient and cannot keep up with the high-speed production pace of modern fireworks production lines, becoming a bottleneck restricting the overall production capacity; on the other hand, fireworks production is a high-risk industry, and direct contact with densely packed paper tubes and potentially residual powder poses certain safety hazards. In addition, manual tube sorting makes it difficult to ensure the consistency and uniformity of the paper tube arrangement, affecting the processing quality of subsequent processes such as powder loading.

[0004] In recent years, automated equipment for fireworks production has received widespread attention and development. For example, patents have disclosed automatic forming and bundling equipment for firecracker tubes, realizing the sorting, assembly, and bundling of tubes; other patents involve components for removing the tie-down straps of inner firecracker tubes, enabling automated removal of the tie-down straps. However, existing automated equipment mostly focuses on the forming and bundling of tubes or the removal of specific types of tie-down straps (such as plastic tie-down straps), and integrated equipment specifically designed for the rapid untying and automatic tube sorting of standard hexagonal firecracker tubes is still lacking. The efficiency bottlenecks and safety risks of manual untying and tube sorting have not been effectively resolved, and there is an urgent need for a dedicated device that can automatically unty and sort firecracker tubes. Summary of the Invention

[0005] To address the above problems, this invention provides an automatic cake feeding and unhooking device for fireworks processing, which solves the problems of automatic cake feeding, unhooking, and subsequent limiting of falling into the cylinder and efficient collection and arrangement.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automatic firework tube feeding and unbinding device for fireworks processing includes a feeding mechanism, a unbinding mechanism, and a tube-dropping limiting mechanism arranged sequentially on a frame. The tube-dropping limiting mechanism is mounted on a vertically mounted plate on the frame. The unbinding mechanism is located at the upper front of the tube-dropping limiting mechanism and is connected to the feeding mechanism. The unbinding mechanism includes a mold frame fixedly connected to the vertical plate via a connecting block. The mold frame has a feeding port for passing firework tubes, and a feeding base plate is located at the bottom of the mold frame to receive the firework tubes. The space between the mold frame and the vertical plate is a tube-exit space, and a limiting member is located in front of the limiting member. The positions of the feeding port, the limiting member, and the tube-exit space correspond to each other. A clamping member and a pushing member of the feeding mechanism are arranged sequentially in front of the limiting member.

[0007] As a further improvement to the above solution, the cylinder dropping limiting mechanism includes a cylinder limiting component and a cylinder dropping component in the same vertical direction as the cylinder outlet space; the cylinder limiting component includes a cylinder limiting top moving plate and a cylinder limiting bottom moving plate, the two ends of the cylinder limiting top moving plate are connected to the top moving plate cylinder on the vertical plate through connecting rods, and the connecting rods slide up and down in the sliding groove opened on the vertical plate; the cylinder limiting bottom moving plates are arranged in pairs and the outer end is connected to the bottom moving plate cylinder fixedly installed on the vertical plate.

[0008] As a further improvement to the above scheme, the bottom of the limiting cylinder bottom plate is a cylinder passage, and the bottom of the cylinder passage is a drop hopper connected to the collection and distribution cylinder mechanism.

[0009] As a further improvement to the above solution, the collecting cylinder mechanism includes a collecting component connected to the silo; the collecting component includes an arc-shaped collecting trough located directly below the silo, and a horizontal pusher rod is provided at the front end of the top of the arc-shaped collecting trough; a vibrating cylinder groove is provided at the bottom of the arc-shaped collecting trough, and an eccentric swinging component is connected to the vibrating cylinder groove on the frame; a collecting cylinder base for collecting the cylinder is provided below the bottom end of the arc-shaped collecting trough, and a vertical pusher rod for pushing the cylinder into the collecting cylinder base is provided directly above the bottom end of the arc-shaped collecting trough.

[0010] As a further improvement to the above solution, the collecting tube mechanism also includes a tube component, which includes a horizontal drive pulley connected to the driving tube base; a stopper rod is provided above one end of the horizontal drive pulley for pushing the material tube in the collecting tube base into the fireworks tube holder; the frame is provided with guiding tube guide rails on both sides of the collecting tube base, and the fireworks tube holder is set on the tube conveyor belt below one end of the horizontal drive pulley.

[0011] As a further improvement to the above solution, the limiting clamp includes a limiting clamp moving plate symmetrically arranged above the outlet space, and the tail end of the limiting clamp moving plate is drivenly connected to a limiting clamp cylinder that is obliquely fixed on the vertical plate; the base plate of the cake is V-shaped and the upper surface is provided with a limiting clamp groove for accommodating the bottom of the firework cake.

[0012] As a further improvement to the above solution, the cake feeding mechanism includes a cylinder cake conveyor belt and a vertical cake component disposed in front of the cylinder cake conveyor belt; guide rails are provided on both sides of the cylinder cake conveyor belt; the vertical cake component includes a cake receiving plate fixedly disposed in front of one end of the cylinder cake conveyor belt, and a flip-up cake-turning plate is disposed behind the cake receiving plate; the flip-up cake-turning plate is provided with a cake receiving groove for accommodating firework cylinders, and the cake receiving groove has a cake-turning notch on both sides for the cake-turning component to contact and clamp the firework cylinder; one end of the flip-up cake-turning plate is movably connected to the frame through a flip-up plate pivot, and a flip-up plate cylinder fixedly disposed on the frame is drivenly connected to the bottom of the flip-up cake-turning plate.

[0013] As a further improvement to the above solution, the cake feeding mechanism also includes a sliding base and a sliding cylinder fixedly mounted on the frame. The movable end of the sliding cylinder is connected to the sliding base, and the sliding base slides in cooperation with the slide rail fixedly mounted on the frame.

[0014] As a further improvement to the above solution, a clamping component is provided at one end of the sliding base. The clamping component includes a lifting cylinder fixedly mounted on the sliding base. The bottom of the lifting cylinder is provided with a clamping claw that cooperates with the clamping notch. The clamping claw is connected to a clamping cylinder that drives it to clamp inward. The inner wall of the clamping claw is provided with protrusions.

[0015] As a further improvement to the above solution, a cake-pushing component is provided at the other end of the sliding base. The cake-pushing component includes a cake-pushing base fixedly mounted on the sliding base, and a cake-pushing cylinder is provided on the cake-pushing base. A cake-pushing block corresponding to the position of the cake-clamping component is provided at the front end of the cake-pushing cylinder, and a guide frame is provided on the outside of the cake-pushing block on the cake-pushing base.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This application integrates the entire processing of fireworks tube cakes from a bound state to an ordered tube into a fully automated production line operation through the sequential connection and coordinated cooperation of the cake feeding mechanism, the unbinding mechanism, the material dropping limiting mechanism, and the tube collecting mechanism. The entire process requires no manual intervention, and the cycle of unbinding and tube sorting can be completed within a few seconds. Compared with the traditional manual unbinding and tube sorting method, the production efficiency can be increased by several times or even more than ten times, effectively matching the high-speed rhythm of modern fireworks production lines and eliminating the capacity bottleneck caused by manual operation. This application employs a regular hexagonal mold cavity that matches the shape of the hexagonal tube to provide full circumferential restraint for the tube. Combined with the retaining groove on the base and the retaining plates on the top and sides, the retaining rings are evenly dislodged along the circumference of the tube by the pushing block of the pusher, avoiding damage to the ends of the paper tube or scratches on adjacent paper tubes caused by improper operation during manual clamping. Simultaneously, the small gap between the inner wall of the mold frame and the outer wall of the tube, as well as the protrusions on the clamping claws, further ensure the structural integrity of the paper tube during the clamping process, improving product yield. This application achieves controlled release of scattered paper tubes after unhooking by using a bottom moving plate and a top moving plate. Then, through the coordinated action of the tube channel and the transverse push rod, the originally scattered and disordered firework tubes are automatically organized into a uniformly oriented and neatly arranged sequence in an arc-shaped collection trough. This orderly arrangement not only ensures the consistency and uniformity of the paper tube arrangement but also provides a reliable material supply foundation for subsequent processes such as loading and sealing. This application replaces the manual, direct contact with the firework tubes for unpacking and sorting with automated equipment within a closed or semi-closed workstation. Operators only need to replenish the firework tubes at the feeding end and collect the finished tubes at the collection end, significantly reducing direct contact between operators and the firework tubes (especially those potentially containing residual powder). Simultaneously, the unpacking, unloading, and sorting processes are all carried out systematically inside the equipment, effectively reducing the spread of firework dust and the risk of personnel exposure, fundamentally improving the safety and occupational health of firework production operations. Furthermore, automated operation reduces reliance on a large number of skilled operators, alleviating the problems of labor shortages and high labor costs in the fireworks industry.

Detailed Implementation

[0026] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Overall structure of the equipment like Figure 1 As shown, an automatic fireworks feeding and unhooking device for fireworks processing includes a frame 1 and a feeding mechanism 2, an unhooking mechanism 3, and a falling tube limiting mechanism 4 sequentially arranged on the frame 1. The frame 1 adopts a steel structure frame, providing an installation foundation for each mechanism. A vertical plate 11 is vertically arranged on the frame 1, and the falling tube limiting mechanism 4 is arranged on the vertical plate 11. The unhooking mechanism 3 is arranged on the upper front side of the falling tube limiting mechanism 4, and the unhooking mechanism 3 is connected to the feeding mechanism 2. The mechanisms are arranged sequentially on the frame 1 along the processing flow direction of the fireworks tube 6, forming a continuous production line from feeding, unhooking to falling tube limiting.

[0028] II. Specific Structure of the Pancake Delivery Mechanism 2 like Figures 1-8As shown, the cake feeding mechanism 2 includes a cake conveyor belt 21 and a vertical cake component 22 disposed in front of the cake conveyor belt 21. The cake conveyor belt 21 is a belt conveyor driven by a transmission motor mounted on the frame 1, used to transport the firework cakes 6 (with hoops) to be processed from the previous station to the vertical cake component 22. The conveying direction of the cake conveyor belt 21 is horizontal, and its width is adapted to the external dimensions of the firework cakes 6.

[0029] The vertical cake-collecting component 22 includes a cake-receiving plate 221 fixedly disposed in front of one end of the cake-collecting conveyor belt 21. The cake-receiving plate 221 is horizontally disposed, and its height is flush with the conveying surface of the cake-collecting conveyor belt 21, for receiving the firework cakes 6 output from the end of the cake-collecting conveyor belt 21. A flip-up cake-collecting plate 226 is disposed behind the cake-receiving plate 221. The flip-up cake-collecting plate 226 has a cake-collecting groove 222 for accommodating the firework cake 6. The shape of the cake-collecting groove 222 matches the shape of the firework cake 6 and is a regular hexagonal groove structure. Claw-collecting notches 223 are provided on both sides of the cake-collecting groove 222. The claw-collecting notches 223 penetrate the side wall of the flip-up cake-collecting plate 226 for the clamping claws 232 of the subsequent cake-collecting component 23 to extend into and clamp the firework cake 6. One end of the flipper plate 226 is movably connected to the frame 1 via the flipper shaft 224, and the bottom of the flipper plate 226 is connected to a flipper cylinder 225 fixedly mounted on the frame 1. The cylinder body of the flipper cylinder 225 is fixed on the frame 1, and the end of its piston rod is hinged to the bottom of the flipper plate 226.

[0030] The cake feeding mechanism 2 also includes a sliding base 25 and a sliding cylinder 26 fixedly mounted on the frame 1. The sliding cylinder 26 is a rodless cylinder or a conventional cylinder, and its movable end is fixedly connected to the sliding base 25. The sliding base 25 is slidably engaged with a slide rail 12 fixedly mounted on the frame 1, and the slide rail 12 extends horizontally. Driven by the sliding cylinder 26, the sliding base 25 can reciprocate horizontally along the slide rail 12.

[0031] A clamping element 23 is provided at one end of the sliding base 25. The clamping element 23 includes a lifting cylinder 233 fixedly mounted on the sliding base 25. The lifting cylinder 233 is vertically mounted with its piston rod pointing downwards. The bottom of the lifting cylinder 233 is provided with clamping claws 232 that cooperate with the clamping notch 223. The clamping claws 232 are two opposing claw bodies with an L-shaped or arc-shaped structure. The clamping claws 232 are connected to a clamping cylinder 231, which drives the two clamping claws 232 to clamp inwards or open outwards. Preferably, the inner wall of the clamping claws 232 is provided with protrusions 2321, which are hemispherical or strip-shaped protrusions 2321, to increase the friction between the clamping claws 232 and the firework tube cake 6 and prevent the firework tube cake 6 from slipping off during the clamping process.

[0032] A pusher component 24 is provided at the other end of the sliding base 25. The pusher component 24 includes a pusher base 241 fixedly mounted on the sliding base 25, and a pusher cylinder 242 is provided on the pusher base 241. The pusher cylinder 242 is horizontally positioned, with its piston rod facing the direction of the unbuncturing mechanism 3. A pusher block 243 is provided at the front end of the pusher cylinder 242, and the position of the pusher block 243 corresponds to the position of the clamping component 23, that is, the pusher block 243 and the clamping claw 232 are at the same height in the horizontal direction. A guide frame 244 is provided on the outside of the pusher block 243 on the pusher base 241. The guide frame 244 is a U-shaped or square frame structure, used to guide and limit the firework tube cake 6 when the pusher block 243 pushes it, to prevent the firework tube cake 6 from deviating during the pushing process.

[0033] III. Specific Structure of the Hoop Removal Mechanism 3 like Figures 1-6 As shown, the unhooking mechanism 3 includes a mold frame 31 fixedly connected to the upright plate 11 via a connecting block 36. The mold frame 31 is a frame structure with a regular hexagonal inner cavity, the shape of which matches the shape of the firework tube cake 6. The mold frame 31 has a passage opening 32 for the firework tube cake 6 to pass through. The passage opening 32 is an opening on the front side wall of the mold frame 31, its shape and size adapted to the shape of the firework tube cake 6, allowing the firework tube cake 6 to enter the mold frame 31 from the front. The bottom of the mold frame 31 is provided with a support plate 34 for receiving the firework tube cake 6. The support plate 34 is V-shaped, meaning its cross-section is V-shaped, used for bottom positioning and support of the firework tube cake 6 falling into the mold frame 31. A limiting groove 341 is provided on the upper surface of the base plate 34. The limiting groove 341 is an arc-shaped groove or a V-shaped groove extending along the upper surface of the base plate 34. Its width is adapted to the diameter of the binding ring around the firework tube cake 6 and is used to accommodate and limit the lower part of the binding ring.

[0034] The space between the mold frame 31 and the upright plate 11 is the outlet space 35. The outlet space 35 is the gap area between the rear side wall of the mold frame 31 and the front side of the upright plate 11, and its width is greater than the maximum size of the scattered paper tubes after the firework tube 6 is unhooked. A limiting hoop 33 is provided on the rear side of the mold frame 31 (i.e., the side closest to the upright plate 11). The limiting hoop 33 includes a limiting hoop movable plate 331 symmetrically arranged above the outlet space 35. The limiting hoop movable plate 331 consists of two opposing plates, located on the left and right sides above the outlet space 35 respectively. The tail end of the limiting hoop movable plate 331 is drivenly connected to a limiting hoop cylinder 332 that is obliquely fixed on the upright plate 11. The cylinder body of the limiting hoop cylinder 332 is fixed on the upright plate 11, and its piston rod is hinged to the tail end of the limiting hoop movable plate 331. Driven by the limiting cylinder 332, the two limiting plates 331 can move towards each other or away from each other, thereby clamping and limiting or releasing the hoop of the firework tube cake 6.

[0035] The positions of the through-hole 32, the limiting clamp 33, and the outlet space 35 correspond to each other. That is, after the firework tube cake 6 enters the mold frame 31 through the through-hole 32, its clamp is clamped and limited by the limiting clamp 33. After the clamp is removed, the paper tube falls backward (i.e. towards the vertical plate 11) from the outlet space 35.

[0036] In front of the limiting clamp 33 (i.e., on the side away from the upright plate 11), the cake feeding mechanism 2 has a cake clamping component 23 and a cake pushing component 24 arranged in sequence. Specifically, in the horizontal direction from front to back, they are: the clamping claw 232 of the cake clamping component 23, the cake pushing block 243 of the cake pushing component 24, and the cake passage 32 of the mold frame 31.

[0037] IV. Specific Structure of Drop-off Limiting Mechanism 4 like Figures 1-5 As shown, the paper roll dropping limiting mechanism 4 includes a limiting member 41 and a dropping member 42, which are in the same vertical direction as the paper roll exiting space 35. The limiting member 41 is located directly below the paper roll exiting space 35 and is used to limit and temporarily store the scattered paper rolls falling from the paper roll exiting space 35.

[0038] The cylinder limiting component 41 includes a cylinder limiting top moving plate 411 and a cylinder limiting bottom moving plate 413. The cylinder limiting top moving plate 411 is a horizontally arranged plate, and its two ends are connected to a cylinder limiting plate cylinder 414 mounted on a vertical plate 11 via connecting rods 412. A vertical groove 111 is provided on the vertical plate 11, and the connecting rod 412 passes through the groove 111 and slides up and down within the groove 111. The cylinder body of the cylinder limiting plate cylinder 414 is fixed on the vertical plate 11, and its piston rod is fixedly connected to the connecting rod 412. Driven by the cylinder limiting plate cylinder 414, the cylinder limiting top moving plate 411 can move up and down along the groove 111.

[0039] The bottom moving plates 413 are arranged in pairs, that is, two bottom moving plates 413 are arranged opposite each other, located on the left and right sides of the cylinder passage 43 respectively. The outer ends of the bottom moving plates 413 are connected to the bottom moving plate cylinder 415 fixedly mounted on the vertical plate 11. The cylinder body of the bottom moving plate cylinder 415 is fixed on the vertical plate 11, and its piston rod is fixedly connected to the outer ends of the bottom moving plates 413. Driven by the bottom moving plate cylinder 415, the two bottom moving plates 413 can move towards each other (closed) or away from each other (opened).

[0040] Below the bottom moving plate 413 is the tube passage 43, a vertically arranged cylindrical channel with an inner diameter larger than the outer diameter of a single firework tube, used to allow scattered tubes to pass through one by one. At the bottom of the tube passage 43 is the tube drop chamber 44, a funnel-shaped structure that is wider at the top and narrower at the bottom, used to collect the tubes falling through the tube passage 43 and guide them to the tube collection and distribution mechanism 5 below.

[0041] V. Specific Structure of the Cloth Collection Mechanism 5 like Figures 1-5As shown, the collecting mechanism 5 includes a collecting component 51 connected to the dropping bin 44. The collecting component 51 includes an arc-shaped collecting trough 511 located directly below the dropping bin 44. The arc-shaped collecting trough 511 is a long trough structure with a circular or U-shaped cross-section, extending horizontally along its length, used to collect the firework paper tubes falling from the dropping bin 44. A transverse push rod 512 is provided at the top front end of the arc-shaped collecting trough 511. The transverse push rod 512 is a horizontally positioned rod connected to a transverse push cylinder, which can reciprocate horizontally along the length of the arc-shaped collecting trough 511 to push the paper tubes within the arc-shaped collecting trough 511 to one side.

[0042] A vibrating tube passage 513 is provided at the bottom of the arc-shaped collection trough 511. The vibrating tube passage 513 is a trough structure that communicates with the bottom of the arc-shaped collection trough 511, and its width is adapted to the outer diameter of a single firework paper tube. The vibrating tube passage 513 is driven by an eccentric swing member 514 mounted on the frame 1. The eccentric swing member 514 includes an eccentric wheel and a drive motor, and the eccentric wheel is in contact with the bottom of the vibrating tube passage 513. Driven by the drive motor, the eccentric wheel rotates and generates periodic vibration, causing the vibrating tube passage 513 to generate high-frequency small-amplitude vibration, which promotes the orderly entry of the paper tubes in the arc-shaped collection trough 511 into the vibrating tube passage 513 and their arrangement along its length.

[0043] A collecting cylinder base 515 for collecting material tubes is provided below the bottom end of the arc-shaped collecting trough 511. The collecting cylinder base 515 is a horizontally arranged plate or trough, and its upper surface has a receiving groove adapted to the shape of the fireworks paper tube. A vertical pusher rod 516 is provided directly above the bottom end of the arc-shaped collecting trough 511. The vertical pusher rod 516 is a vertically arranged rod connected to a vertical pusher cylinder, which can move up and down in the vertical direction to push the material tubes arranged at the bottom end of the arc-shaped collecting trough 511 into the collecting cylinder base 515.

[0044] The cloth collection mechanism 5 also includes a cloth collection tube component 52. The cloth collection tube component 52 includes a horizontal drive pulley 521 that connects to the drive collection tube base 515. The horizontal drive pulley 521 includes a driving pulley, a driven pulley, and a conveyor belt surrounding the driving pulley and the driven pulley. The collection tube base 515 is fixedly mounted on the conveyor belt. Driven by a drive motor, the horizontal drive pulley 521 can move the collection tube base 515 horizontally.

[0045] A stopper rod 523 is installed above one end of the horizontal drive pulley 521. The stopper rod 523 is a vertically arranged rod connected to a stopper rod cylinder, which can move up and down vertically to push the material cylinder in the collecting cylinder base 515 into the firework tube holder 525 below. The frame 1 has guide rails 522 on both sides of the collecting cylinder base 515, which extend horizontally to guide the movement of the collecting cylinder base 515. The firework tube holder 525 is mounted on a material cylinder conveyor belt 524 below one end of the horizontal drive pulley 521. The material cylinder conveyor belt 524 is a belt conveyor used to transport the firework tube holder 525 filled with material cylinders to the next station.

[0046] VI. Equipment Working Process The working process of the automatic cake loading and unloading device for fireworks processing of the present invention is as follows: (a) The cake delivery stage The firework tube cake 6 (with the hoop) to be processed is conveyed by the tube cake conveyor belt 21 to the cake receiving plate 221 of the vertical cake component 22. Subsequently, the flipping cylinder 225 is activated, driving the flipping plate 226 to rotate around the flipping shaft 224, so that the flipping plate 226 is flipped from a horizontal state to a vertical state. At this time, the firework tube cake 6 falls into the cake receiving groove 222 of the flipping plate 226 and stands upright together with the flipping plate 226. Next, the sliding cylinder 26 drives the sliding base 25 to move along the slide rail 12 toward the flipping plate 226, so that the clamping claw 232 of the cake clamping component 23 is aligned with the cake clamping notch 223 on the flipping plate 226. The lifting cylinder 233 drives the clamping claw 232 to descend to the position of the clamping notch 223. The clamping cylinder 231 drives the clamping claw 232 to clamp inward. The protrusion 2321 on the inner wall of the clamping claw 232 makes close contact with the outer wall of the firework tube cake 6, clamping and fixing the firework tube cake 6. Then, the flipping cylinder 225 moves in the opposite direction, so that the flipping plate 226 returns to the horizontal state. The sliding cylinder 26 continues to drive the sliding base 25 to move towards the unhooking mechanism 3. The clamping claw 232, holding the firework tube cake 6, disengages from the cake receiving groove 222 of the flipping plate 226 and moves towards the cake passage 32 of the mold frame 31.

[0047] (II) Removal of clamps When the gripper 232 delivers the firework tube cake 6 to the front of the cake-passing opening 32 of the mold frame 31, the cake-pushing cylinder 242 activates, driving the cake-pushing block 243 to extend forward. The cake-pushing block 243 passes through the guide frame 244, pushing the firework tube cake 6 from the cake-passing opening 32 into the mold frame 31. The firework tube cake 6 continues to move backward under the push of the cake-pushing block 243 until its outer binding ring reaches the position of the limiting ring 33. At this time, the limiting ring cylinder 332 activates, driving the two limiting ring moving plates 331 to move towards each other, clamping the ring from both sides. Simultaneously, the limiting ring groove 341 on the cake-supporting base plate 34 limits the ring from below. Under the continuous push of the cake-pushing block 243, the tube body of the firework tube cake 6 continues to move backward, while the ring, limited by the limiting ring moving plates 331 and the limiting ring groove 341, cannot move with it, thus separating the ring from the tube body of the firework tube cake 6. After separation, the hoop falls downwards under gravity and is discharged outside the equipment through the discharge port below the tube outlet 35. The firework paper tube, after the hoop is removed, unfolds and falls backwards from the tube outlet 35.

[0048] (III) Dropping and Limiting Stage The loose paper tubes that detach from the outlet space 35 fall into the area of ​​the limiting plate 41. At this time, the bottom moving plate 413 of the limiting plate is in a closed state driven by the bottom moving plate cylinder 415, and the two bottom moving plates 413 together support the loose paper tubes. The top moving plate 411 of the limiting plate moves downward under the drive of the top moving plate cylinder 414, limiting and organizing the loose paper tubes from above, preventing the paper tubes from becoming excessively scattered or blocked during the falling process. After a short period of temporary storage and organization, the bottom moving plate cylinder 415 drives the bottom moving plate 413 of the limiting plate to move in the opposite direction and open, and the loose paper tubes fall into the dropping chamber 44 through the passing channel 43 under the action of gravity. The top moving plate 411 of the limiting plate then resets upward under the drive of the top moving plate cylinder 414, ready to receive the next batch of loose paper tubes.

[0049] (iv) Collection of cloth tubes stage Firework paper tubes falling from the hopper 44 enter the arc-shaped collection trough 511. Under the vibration of the eccentric swinging component 514, the vibrating tube groove 513 generates high-frequency small-amplitude vibrations, causing the paper tubes in the arc-shaped collection trough 511 to arrange themselves orderly along the length of the arc-shaped collection trough 511. The transverse push rod 512, driven by the transverse push cylinder, moves periodically, pushing the paper tubes in the arc-shaped collection trough 511 towards the bottom. When the paper tubes reach the bottom of the arc-shaped collection trough 511, the vertical push rod 516, driven by the vertical push cylinder, moves downward, pushing the paper tubes into the collecting base 515. The collecting base 515, driven by the horizontal drive pulley 521, moves horizontally along the tube distribution guide rail 522, moving the collecting base 515, now loaded with paper tubes, to a position above the tube distribution conveyor belt 524. Subsequently, the stopper rod 523 moves downward under the drive of the stopper rod cylinder, pushing the paper tube in the collecting tube base 515 into the firework tube holder 525 below. The firework tube holder 525, filled with paper tubes, is transported to the next station by the tube conveyor belt 524 for subsequent processing steps such as loading and sealing.

[0050] At this point, a complete cycle of automatic loading, unhooking, tube lowering, and collection of the firework tube is completed.
