Description

Technical Field

[0001] This application relates to the field of fireworks production technology, specifically to an assembly device for aerial fireworks. Background Technology

[0002] Fireworks, as a representative of traditional Chinese culture, have a long history. The production process of fireworks products has extremely high safety requirements. Due to the high risk involved in gunpowder loading, cartridge loading and fireworks assembly are carried out separately. Depending on the type of fireworks, assembly is done manually or using semi-automatic devices.

[0003] Aerial fireworks mainly refer to fireworks such as skyrockets and rockets. These fireworks are manufactured using rocket principles. They have a tube handle made of bamboo or wood, with the tube wrapped in a label and fixed to the head of the handle. When the gunpowder inside the tube is ignited, the burning gunpowder ejects a stream of air towards the tail, propelling the tube upwards into the air. The handle plays a balancing and guiding role during the firework's flight, increasing its altitude and flight time. Due to their simple structure and combined visual appeal and entertainment value, these fireworks have a large market demand and are often assembled using automated equipment to meet this need.

[0004] CN202410556506.4 discloses an automatic production equipment for firework rockets, comprising a chassis and a workstation, a rocket barrel input device, a bamboo skewer input device, a label dispensing device, and a receiving tray mounted on the chassis. A cam divider is installed on the chassis, and the workstation is mounted on the output shaft of the cam divider. The workstation is equipped with several clamping mechanisms for holding the rocket barrels and bamboo skewers, arranged in a circular array. The rocket barrel input device, the bamboo skewer input device, the label dispensing device, and the receiving tray are sequentially arranged on the outer side of the workstation, corresponding to the positions of the clamping mechanisms. This technical solution uses specialized clamping mechanisms to clamp the rocket barrels and bamboo skewers and deliver them to the labeling station, completing the labeling of the rocket barrels and bamboo skewers. However, the clamping mechanisms increase the complexity of the device's operation, limit its speed, and affect the speed and efficiency of fireworks assembly. Utility Model Content

[0005] This application provides an assembly apparatus for aerial fireworks, which aims to at least improve one of the technical problems existing in the prior art.

[0006] In accordance with the above objectives, this application provides an assembly apparatus for aerial fireworks, including a frame, and further comprising:

[0007] An assembly mechanism is used to wrap the firework tube and handle with label paper to complete the assembly of aerial fireworks. The assembly mechanism includes a loading mechanism and a material-rubbing mechanism. The loading mechanism is equipped with a loading seat for placing the label paper, firework tube, and handle. The label paper is laid flat on the loading seat with the adhesive side facing outwards. The handle is placed flat on the label paper. The firework tube is placed flat on the side of the loading seat facing the material-rubbing mechanism. The loading seat moves relative to the material-rubbing mechanism and passes by it. The material-rubbing mechanism rubs the firework tube on the loading seat as it passes by, causing it to rotate and wrap around the label paper. The firework tube sticks to the label paper and continues to rotate and wrap around the handle, completing the wrapping of the firework tube and handle with the label paper.

[0008] Furthermore, the material-rubbing mechanism includes a rubbing part, which has a first gap S and a first included angle α with the material-filling seat it passes through. When the firework tube passes through the first gap S with the first included angle α, the rubbing part generates a corresponding force on the firework tube, causing the firework tube to rotate to overcome the force exerted by the material-filling seat on the firework tube.

[0009] Furthermore, the loading mechanism also includes a rotating wheel, and the loading seat is circumferentially disposed on the surface of the rotating wheel. The rotation of the rotating wheel drives the loading seat to move and pass through the material-rubbing mechanism. The material-rubbing mechanism also includes a mounting part and an extension part. The mounting part is disposed on the frame. One end of the extension part is connected to the mounting part, and the other end is connected to the rubbing part. The extension part has an adjustable telescopic structure. Adjusting the telescopic structure can change the relative position of the rubbing part and the loading mechanism, thereby adjusting the first gap S.

[0010] Furthermore, an adjusting member is provided between the extension and the mounting part. The adjusting member is provided with a first adjusting groove and a second adjusting groove. The mounting part is provided with a first mounting hole corresponding to the first adjusting groove. The first adjusting groove and the first mounting hole are connected by bolts. Adjusting the bolt in the locking position of the first adjusting groove can change the first included angle α. The extension is provided with a second mounting hole corresponding to the second adjusting groove. The second adjusting groove and the second mounting hole are connected by bolts. Adjusting the bolt in the locking position of the second adjusting groove can change the horizontal position of the rubbing part relative to the loading mechanism.

[0011] Furthermore, the rubbing part is bolted to the extension part, and the rubbing part rotates around the bolt to change the first included angle α.

[0012] Furthermore, the height of the first gap S is 0.7-1cm, and the first included angle α is 10-15°.

[0013] Furthermore, the surface of the loading seat is provided with a first groove and a second groove, the direction of the first groove and the second groove being perpendicular to the moving direction of the loading seat relative to the material rolling mechanism. The first groove is located in the middle of the loading seat, and the second groove is located on the side of the loading seat away from the material rolling mechanism.

[0014] Furthermore, the width of the first groove is 0.2-0.4cm, which is used to cooperate with the positioning of the tube handle on the material base. There can be one or two first grooves. The width of the second groove is 0.6-1cm, which is used to accommodate and reduce the height of the firework tube wrapped with the label paper on the material base so as to disengage it from the material rolling mechanism.

[0015] Furthermore, the surface of the loading seat is also provided with a third groove, which is perpendicular to and penetrates the first groove and the second groove. The surface of the loading seat between the third groove and the first groove and the second groove is also provided with a plurality of air suction holes.

[0016] Furthermore, it also includes a feeding mechanism and a collecting mechanism. The feeding mechanism sequentially feeds the label paper, tube handle and firework tube into the loading seat, and the collecting mechanism collects the assembled finished product.

[0017] This application has the following beneficial effects: the label paper, firework tube and tube handle are placed in the loading seat in an appropriate manner. When the loading seat passes through the material rolling mechanism, the firework tube is rolled and rotated to stick the label paper into the firework tube and tube handle. The assembly is automatically completed during the movement of the loading mechanism without the need for an additional clamping mechanism. The device is simple and efficient to operate, and improves the speed and efficiency of firework assembly.

The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0040] Aerial fireworks, referring to fireworks like skyrockets and firecrackers, mainly consist of two parts: the firework tube and the stem. The tube and stem are wrapped together using label paper, completing the assembly. The label paper has adhesive properties to prevent the wrapping from coming loose. This adhesiveness is achieved by applying glue to the surface of the label paper or by using label paper with an adhesive side. Since the evenness of glue application and drying time affect adhesion, using label paper with an adhesive side provides more stable bonding.

[0041] The following reference Figure 1-10This application describes an assembly apparatus for aerial fireworks according to some embodiments.

[0042] An assembly device for aerial fireworks includes a frame 1 and an assembly mechanism 2. The assembly mechanism 2 includes a loading mechanism 21 and a material feeding mechanism 22. The loading mechanism 21 is provided with a loading seat 211, on which the label paper 51, firework tube 52, and tube handle 53 required for assembling the fireworks are placed. In order to meet the subsequent automatic assembly, the label paper 51, firework tube 52, and tube handle 53 are placed in a compatible manner on the loading seat, that is, the label paper 51 is laid flat on the loading seat 211 with the adhesive side of the label paper 51 facing outwards, the tube handle 53 is placed flat on the label paper 51, and the firework tube 52 is placed flat on the side of the loading seat 211 facing the material feeding mechanism 22. After assembly begins, the loading base 211 moves relative to and approaches the material-rubbing mechanism 22. When passing the material-rubbing mechanism 22, the upper part of the firework tube 52 on the loading base 211 comes into contact with the material-rubbing mechanism 22. Under the continuous relative movement of the material-rubbing mechanism 22 and the loading base 211, the contact of the material-rubbing mechanism 22 with the upper part of the firework tube 52 changes to the rubbing motion of the firework tube 52. Since the firework tube 52 is cylindrical, it rotates back under the rubbing motion of the material-rubbing mechanism 22. After the rotating firework tube 52 comes into contact with the label paper 51 with the adhesive side facing out, the label paper 51 adheres to the surface of the firework tube 52 and wraps the firework tube 52 under the continuous rotation of the firework tube 52. When the firework tube 52, with the label paper 51 attached, rotates back to the tube handle 53, the label paper 51 carries the tube handle 53 in to continue wrapping the firework tube 52, and finally the label paper 51 wraps the firework tube 52 and the tube handle 53.

[0043] For details, see attached. Figure 3-4As shown, the material-rubbing mechanism 22 includes a rubbing part 221, which has a first gap S and a first included angle α with the material-filling seat 211 it passes through. Since the firework tube 52 is cylindrical, the surface of the firework tube 52 that contacts the rubbing part 221 is arc-shaped. The first gap S is the gap formed when the rubbing part 221 and the material-filling seat 211 pass each other. The height of the first gap S is the shortest straight-line distance when the rubbing part 221 and the material-filling seat 211 pass each other. The height of the first gap S must be less than the outer diameter of the firework tube 52 so that the rubbing part 221 can maintain continuous contact with the firework tube 52 that enters the first gap S. Based on the outer diameter of the firework tube 52 of the main aerial fireworks currently on the market, the height of the first gap S is 0.7-1cm. In order to transform the contact into rubbing and rotating of the firework tube 52, the rubbing part 221... The 21 and the charging seat 211 are not parallel to each other but have a first included angle α. The first included angle α refers to the angle between the opposing surfaces of the 221 and the charging seat 211 when the rubbing part 221 passes by the charging seat 211. The first included angle α is 10-15°. The first gap S with this first included angle α is approximately a trumpet mouth, so that after the rubbing part 221 comes into contact with the firework tube 52, part of the force of the rubbing part 221 on the firework tube 52 is converted into a force on the firework tube 52 along the tangent direction of the arc surface, forming a rubbing action of the rubbing part 221 on the surface of the firework tube 52. The rubbing action on the firework tube 52 causes the firework tube 52 to rotate to overcome the force of the charging seat 211 on the firework tube 52.

[0044] In the technical solution of this embodiment, the loading mechanism 21 further includes a rotating wheel 212, and a plurality of loading seats 211 are continuously arranged on the surface of the rotating wheel 212 in the circumferential direction. The material rubbing mechanism 22 further includes a mounting part 222 and an extension part 223. The mounting part 222 is fixedly arranged on the frame 1. The loading seat 211 moves toward the material rubbing mechanism and passes through the material rubbing mechanism 22 under the drive of the rotating wheel 212. Before the loading seat 211 moves and passes through the material-rubbing mechanism 22, the feeding mechanism 3 places the label paper 51, the tube handle 53, and the firework tube 52 onto the loading seat 221 in a suitable manner. As multiple loading seats 211 pass through the material-rubbing mechanism 22 in succession, the label paper 51, the tube handle 53, and the firework tube 52 are continuously assembled into finished products and leave the loading seat 211. The empty loading seat 211 is then filled with the label paper 51, the tube handle 53, and the firework tube 52 by the feeding mechanism 3 and continues to move and pass through the material-rubbing mechanism 22. This cycle is repeated continuously to achieve the continuous automatic assembly of aerial fireworks. The insertion of the label paper 51, tube handle 53, and firework tube 52 into the feeding mechanism 3 does not require special clamping devices for the tube handle 53 and firework tube 52. It only requires arranging these feeding devices in a certain order and orientation in conjunction with the loading seat 211, making the overall device relatively simple. Furthermore, the assembly of the firework tube 52 is completed simultaneously with the operation of the feeding mechanism 3 and the loading mechanism 21, without restricting their operation, ensuring the overall operating speed of the device, and improving the speed and efficiency of firework assembly. One end of the extension 223 is connected to the mounting part 222, and the other end is connected to the agitator 221. The extension 223 has an adjustable telescopic structure; adjusting the telescopic structure changes the relative position of the agitator 221 and the loading mechanism 21, thereby adjusting the first gap S.

[0045] For details, see attached. Figure 5As shown, an adjusting member 224 is also provided between the extension part 223 and the mounting part 222. The adjusting member 224 is provided with a first adjusting groove 2241 and a second adjusting groove 2242. The mounting part 222 is provided with a first mounting hole 2221 corresponding to the first adjusting groove 2241. The adjusting member 224 can be connected to the mounting part 222 by bolting the first adjusting groove 2241 and the first mounting hole 2221. The extension part 223 is provided with a second mounting hole 2231 corresponding to the second adjusting groove 2242. The adjusting member 224 can be connected to the extension part 223 by bolting the second adjusting groove 2242 and the second mounting hole 2231. By adjusting the bolt to the locked position of the first adjustment groove 2241, the extension 223 connected to the adjustment member 224 can swing up and down to change the first included angle α of the rubbing part 221, so as to adapt to firework tubes 52 with different outer diameters within a certain range; and by adjusting the bolt to the locked position of the second adjustment groove 2242, the horizontal position of the rubbing part 221 relative to the loading mechanism 21 can be changed, so that firework tubes 52 of different lengths can be aligned with the first gap S in the horizontal direction and enter.

[0046] Furthermore, the rubbing part 221 is also connected to the extension part 223 by bolts, and the first included angle α of the rubbing part 221 can be changed by rotating the rubbing part 221 around the bolts. Compared with changing the first included angle α by swinging the extension part 223 up and down through the adjusting member 224, directly adjusting the rubbing part 221 can change the first included angle α by a larger range. Therefore, different methods of changing the first included angle α can be selected according to different outer diameter firework tubes 52 and different assembly speeds.

[0047] The extension section 223 can use conventional drive devices such as pneumatic cylinders or hydraulic cylinders to extend or retract the rubbing section 221. During device debugging, specification switching, maintenance and cleaning, the loading structure 21 and the rubbing mechanism 22 can be quickly separated to facilitate related processing.

[0048] In applying the technical solution of this embodiment, as shown in the appendix Figure 6-7 As shown, a first groove 2211 and a second groove 2212 are provided on the surface of the loading seat 221. The arrangement direction of the first groove 2211 and the second groove 2212 is perpendicular to the moving direction of the loading seat 221 relative to the material rolling mechanism 22. The first groove 2211 is located in the middle of the loading seat 221, and the second groove 2212 is located on the side of the loading seat 221 away from the material rolling mechanism 22.

[0049] Specifically, the width of the first groove 2211 is 0.2-0.4cm, which is comparable to the width range of the tube handle 53 currently used in aerial fireworks. When the tube handle 53 is placed in the filling seat 221, it lies flat on the adhesive surface of the label paper 51 facing outwards. Due to the adhesive effect of the adhesive surface, the tube handle 53 has a certain stability when the filling seat 221 moves and will not move easily. However, if the tube handle 53 moves accidentally and slides into the first groove 2211, the movement stops, and the tube handle 53 returns to a stable position, allowing the subsequent label paper 51 to wrap the tube handle 53 normally. Therefore, in order to improve the restriction on the possible movement of the tube handle 53, two first grooves 2211 can also be set adjacent to each other. In this way, even if the first first groove 2211 can block the movement of the tube handle 53, the adjacent second first groove 2211 can also complete the blocking of the tube handle 53, ensuring the stable positioning of the tube handle 53 on the filling seat 221.

[0050] The width of the second groove 2212 is 0.6-1cm, which is roughly the same as the outer diameter of the firework tube 52. As the charging seat 221 moves closer to the material-rubbing mechanism 22, the firework tube 52 rotates under the rubbing action of the material-rubbing mechanism 22. While the firework tube 52 rotates, the charging seat continues to move toward the material-rubbing mechanism 22 until the side of the charging seat where the second groove 2212 is located approaches the material-rubbing mechanism 22. Driven by the rotation of the firework tube 52, the label paper 51 has completely wrapped around the firework tube 52 and the tube handle 53. The assembled firework tube 52 rolls into the second groove 2212 in whole or in part. Because the second groove 2212 reduces the protrusion height of the firework tube 52 on the charging seat 221, this protrusion height is less than the height of the first gap S, so that the material-rubbing mechanism 22 cannot contact the firework tube 52. The assembled firework tube 52 leaves the material-rubbing mechanism 22 as the charging seat 221 passes through the first gap S, and the assembly is completely completed. The assembled finished product is collected by the collection mechanism 4.

[0051] A third groove 2213 is also provided on the surface of the loading base 221. The third groove 2213 is perpendicular to and passes through the first groove 2211 and the second groove 2212. The surface of the loading base 221 between the third groove 2213 and the first groove 2211 and the second groove 2212 is also provided with multiple air suction holes 2214. The air suction holes 2214 are connected to the air suction system of the device. The air suction system generates suction force on the corresponding surface of the loading base 221 through the air suction holes 2214, thereby realizing that the label paper 51 is laid flat and fixed on the loading base 221. The third groove 2213 divides the adsorption surface of the label paper 51 and the loading base 221 from a complete large plane into four smaller discontinuous planes, that is, the adsorption force on the label paper 51 is reduced accordingly, making it easier for the label paper 51 to be easily driven and wrapped when the firework tube 52 rotates.

[0052] In the technical solution of this embodiment, the feeding mechanism 3 includes a label feeding mechanism 31, a tube feeding mechanism 32, and a firework tube feeding mechanism 33. They are arranged in sequence according to the rotation direction of the rotating wheel 212 so that the label 51, tube 52, and firework tube 53 can be placed on the loading seat 211 in sequence according to their respective placement methods.

[0053] For details, see attached. Figure 8 As shown, the label feeding mechanism 31 includes a drive wheel assembly 311, a driven wheel assembly 312, a brake wheel 313, a label roll 314, a label collection roll 315, and a guide 316. Continuous labels 51 are drawn from the label roll 314, passing sequentially through the driven wheel assembly 312, the brake wheel 313, and the guide 316. The labels 51 are then attracted to the surface of the loading seat 211 and carried away. The bottom paper of the labels 51 continues to pass through the drive wheel assembly 311 and is wound onto the label collection roll 315. The drive unit of the label feeding mechanism 31 drives the drive wheel assembly 311 and the label collection roll 315 to rotate, pulling the bottom paper of the labels 51 from the rear end to complete the continuous feeding of the labels 51. The brake wheel 313 is located within the driven wheel assembly 312 and can, in the event of abnormal label feeding, use its own weight to contact and restrict the rotation of the label roll 314, stopping the continued feeding of the labels 51. Before entering the paper guide 316, the label paper 51 passes through a detection component (not shown in the figure) to check the integrity of the label paper 51 and ensure the feeding effect.

[0054] As attached Figure 9 As shown, the shank feeding mechanism 32 includes a shank hopper 321, an inner baffle 322, a positioning plate 323, an outer baffle 324, and an inner shroud 325. The inner baffle 322, multiple positioning plates 323, and the outer baffle 324 are arranged in parallel from the inside to the outside to form a roller. The shank hopper 321 holds the shank 53. One side of the shank hopper 321 has an opening that aligns with the roller formed by the inner baffle 322, the positioning plate 323, and the outer baffle 324. The positioning plate 323 has multiple continuous slots corresponding to the shank 53. The bottom of the hopper 321 has a vibration component (not shown in the figure). The vibration component generates vibration to drive the stalk 53 in the hopper 321 to fall into the slot of the positioning plate 323 in the drum through the opening. The drum rotates under the drive of the drive device to take away the falling stalk 53 and send it into the feeding seat 211 to complete the continuous feeding of the stalk 53. The inner baffle 322 and the outer baffle 324 are used to limit the two ends of the falling stalk 52 to prevent it from falling out of the drum. The inner circumference plate 325 is arranged between the positioning plates 323. The lower edge of the inner circumference plate is adapted to the outer edge of the drum to take out the extra stalk 53 in the slot of the positioning plate 323 to ensure that there is only one stalk 53 in each slot.

[0055] As attached Figure 10As shown, the fireworks tube feeding mechanism 33 includes a fireworks tube hopper 331, a fireworks tube deflector 332, and a fireworks tube rotating wheel 333. The fireworks tube hopper 331 is used to feed fireworks tubes 52. The bottom of the fireworks tube hopper 331 is tapered and has a discharge port. The fireworks tube deflector 332 is located at the discharge port, and the fireworks tube rotating wheel 333 is positioned below the discharge port. When the fireworks tube deflector 332 rotates, it feeds the fireworks tubes 52 one by one from the fireworks tube hopper 331 out of the discharge port in a straight line. The fireworks tube rotating wheel 333 has multiple grooves circumferentially arranged to fit the fireworks tubes 52. The fireworks tubes 52 fed out of the discharge port fall into the grooves. The rotation of the fireworks tube rotating wheel 333 feeds the fireworks tubes 52 from the grooves into the loading seat 211, completing the continuous feeding of the fireworks tubes 52.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
