Abstract
Description
Technical Field
[0001] This utility model relates to a fireworks assembly machine, and in particular to the input mechanism of the fireproof paper. Background Technology
[0002] In the prior art, the workflow of a fireworks assembly machine is as follows: a feeding and discharging system feeds multiple fireworks tubes onto a worktable in the required quantity and arranges them in rows (referred to as tube rows); then a pushing device pushes the tube rows on the worktable out in a row along a direction parallel to the central axis of the fireworks tubes, and under the clamping of the worktable and the conveyor roller group, they are sent to the punching and inserting station; a moving inserting system, including a lead wire conveying mechanism, completes the punching and inserting process; then, glue is applied to the sides and top of the fireworks tubes in the tube rows, and the front tube rows enter the forming process in sequence under the push of the rear tube rows. In this process, the forming system stacks and glues multiple tube rows together to form a block-shaped whole. For example, the "Firework Assembly Machine" disclosed in Chinese invention patent document CN 102538597B.
[0003] With increasingly stringent safety and quality requirements for fireworks, fireproof paper needs to be installed on the sides of each tube array to prevent crossfire between arrays and improve the structural strength of the block-shaped assembly formed by multiple arrays. The existing forming system includes a receiving platform that descends step-by-step from the origin, receiving and stacking the tube arrays one by one. After the adhesive on each tube array cures, they are bonded together into a block. Once the receiving platform reaches its bottom position, the block is pushed off the platform, which then returns to its original position to begin the next cycle. However, the existing forming system can only accept individual tube arrays fed by the feeding system and lacks the function of receiving and assembling the fireproof paper, thus failing to meet the requirement of adding fireproof paper between the tube arrays.
[0004] To meet market demand, in our early work, we designed and developed several fireproof paper assembly mechanisms, such as "A fireproof paper processing device for irregularly shaped combined fireworks" (application number 2024202575178); "A fireproof paper assembly mechanism for a fireworks assembly machine forming system" (application number 2023227307094); and "A fireproof paper assembly mechanism for fireworks assembly forming" (application number 2024200256981). All of these mechanisms input the fireproof paper from the side of the receiving platform. If the input direction of the cylinder is defined as the front-to-back direction, the input direction of the fireproof paper is left-to-right. However, in later practical work, we found that this method required transporting the fireproof paper to the receiving platform and then gluing the cylinder and fireproof paper together on the receiving platform, resulting in low processing efficiency and a relatively complex mechanism. Utility Model Content
[0005] To address the aforementioned drawbacks, the technical problem this utility model aims to solve is to provide an input mechanism for the fireproof paper of a fireworks assembly machine, effectively improving the efficiency of assembling the fireproof paper. To solve this technical problem, the present utility model adopts an input mechanism for the fireproof paper of a fireworks assembly machine, comprising a worktable of the fireworks assembly machine and a tube array located on the worktable. The mechanism further comprises: a paper strip for making the fireproof paper, wherein the paper strip is an adhesive paper strip, and the paper strip enters the worktable in the same direction as the tube array's forward movement.
[0006] The pressure rollers set on the worktable act on the drum or the paper tape; the paper tape enters between the worktable and the drum or between the drum and the pressure rollers;
[0007] The paper cutting component is located near the receiving platform of the paper tray machine to cut the paper tape.
[0008] Using the above method, after the paper strip is glued, it enters the worktable. The paper strip is located between the worktable and the drum or between the drum and the pressure roller. Under the action of the pressure roller, the paper strip and the drum are glued together. As the drum is pushed forward, the paper strip moves forward with it, and the two are glued together and enter the receiving platform of the forming system. During this process, the paper cutting component cuts the paper strip, and the drum with the fireproof paper attached is stacked and assembled into a block on the receiving platform.
[0009] The beneficial effects of this utility model are that the paper tape input direction is consistent with the forward direction of the tube assembly, and the paper tape input can be driven by the existing tube assembly force. During the forward movement of the tube assembly, the tube assembly and the fireproof paper are bonded together, effectively improving the processing efficiency of assembling the fireproof paper. The mechanism is simple and reliable in operation. It does not require increasing the width of the pottery assembly machine, effectively reducing the equipment's footprint; and it has good compatibility with existing pottery assembly machines.
[0010] The paper tape can enter the worktable from the front or rear of the moving insertion system, or from the rear of the feeding drum system. In one embodiment, the worktable is provided with a strip-shaped hole for the paper tape to pass through, and the paper tape enters the worktable from below through the strip-shaped hole. This facilitates the paper tape entering the worktable from the front or rear of the moving insertion system, which helps to shorten the distance the paper tape travels between the worktable and the drum.
[0011] In one embodiment, a support roller is further provided below the roll on the worktable, wherein the paper strip is located between the support roller and the roll, or the roll is located between the paper strip and the support roller.
[0012] In one embodiment, a fireproof paper roll for unwinding the paper tape is also included.
[0013] In one embodiment, when the paper strip enters between the worktable and the roll, a roll lifting component is provided corresponding to the paper cutting assembly. The roll lifting component includes a top member that reciprocates up and down. When the top member rises, it lifts the adjacent ends of two adjacent rolls on the worktable. After the adjacent ends of the two adjacent rolls are lifted, they tilt to both sides, thereby exposing the paper strip below the roll, which facilitates the paper cutting assembly to cut the paper strip.
[0014] In one embodiment, the paper cutting assembly includes a guide rail disposed above the worktable, the guide rail axis being perpendicular to the tube input direction, and a movable paper cutter reciprocating along the guide rail to cut the paper strip.
[0015] In one embodiment, the paper cutting assembly includes a lifting cutter positioned above the worktable, the cutter axis being perpendicular to the tube feed direction, the lifting cutter cutting the paper strip as it descends or rises. The cutter may be a serrated cutter.
[0016] The adhesive paper tape can be a paper tape that has already been glued during the initial manufacturing process, such as self-adhesive tape. In one embodiment, the mechanism further includes an adhesive application component for applying adhesive to the paper tape. The adhesive application of the paper tape is completed on-site.
[0017] In the above technical solutions, quick-drying hot melt adhesive can be used to facilitate the bonding of the paper tape and the drum. However, hot melt adhesive is expensive. To facilitate the drying of cheaper ordinary adhesive, the worktable can be appropriately extended to provide sufficient adhesive drying time. In one embodiment, an adhesive drying assembly is also included, which is selected from the heating assembly of the support roller or the hot air supply assembly between the drum and the worktable.
[0018] In one embodiment, the workbench surface is provided with a plurality of spaced positioning strips, the axis of which is parallel to the forward direction of the tube array. Firework tubes are accommodated between adjacent positioning strips, and a gap is provided between the positioning strips and the workbench surface for a paper strip to pass through. This facilitates the arrangement of the spacing of the firework tubes in the tube array as needed, and the individual firework tubes are bonded together into a single tube array using fireproof paper.

[0029] Figure 9 This is a schematic diagram of the principle structure of Example 4. Detailed Implementation
[0030] Example 1: See Appendix Figure 1-5This describes a specific structure of the present invention. The fireworks assembly machine includes a worktable 1. Multiple fireworks tubes are fed onto the worktable 1 in one go by the feeding hopper of the feeding tube system 2, and arranged in rows to form tube rows 3. Then, the rear pushing device pushes the tube rows 3 on the worktable 1 out in a row along a direction parallel to the central axis of the fireworks tube body. Under the clamping of the worktable 1 and the conveying roller group 4, they are sent to the punching and inserting station. At the punching and inserting station, the moving inserting system 5, including the lead wire conveying mechanism, completes the punching and inserting process. Then, glue is applied to the top surface of the fireworks tubes in the tube rows. Under the push of the rear tube rows, the front tube rows enter the forming process in sequence. In this process, the forming system 6 stacks and glues multiple tube rows 3 together to form a block-shaped whole 7.
[0031] In the example, the fireproof paper input mechanism of the fireworks assembly machine also includes a fireproof paper roll 8. After the fireproof paper roll 8 is unwound, a paper strip 9 for making fireproof paper is output. The paper strip 9 enters between the worktable 1 and the cylinder 3. The paper strip 9 can enter the worktable 1 from the front or rear of the moving insertion system 5, or from the rear of the feeding cylinder system 2. In the example, the paper strip 9 enters the worktable 1 from the front of the moving insertion system 5. The worktable 1 is provided with three strip holes 10 for the paper strip 9 to pass through. The example also includes three support rollers 11 set in the strip holes 10 below the cylinder 3 on the worktable 1. The support rollers can effectively reduce the friction between the bottom of the paper strip 9 and the worktable 1, which is beneficial to the bonding of the top of the paper strip 9 and the cylinder 3.
[0032] In the example, after the fireproof paper roll 8 is unwound, the paper strip 9 output passes through the first strip hole 10 from below the worktable 1, goes around the support roller 11, and enters the worktable 1, located between the three support rollers 11 and the tube row 3. This helps to shorten the distance that the paper strip 9 travels between the worktable 1 and the tube row 3. It also avoids the impact of mud from the firework tube scattering or the perforation and insertion on the paper strip.
[0033] The input mechanism also includes a glue application component for applying glue to the paper tape 9. In this example, the component includes a glue box and a glue application roller assembly. In this example, a pressure roller 12 mounted on the worktable 1 acts on the drum 3. After the paper tape 9 is glued, it enters between the support roller 11 on the worktable 1 and the drum 3. Under the action of the pressure roller 12, the paper tape 9 is glued to the bottom surface of the drum 3. To facilitate the bonding of the paper tape and the drum, a quick-drying hot melt adhesive can be used. However, hot melt adhesive is expensive. To facilitate the rapid drying of a cheaper ordinary adhesive, the worktable 1 can be appropriately extended to provide sufficient glue drying time. Alternatively, a glue drying component can be provided, such as a heating component for the support roller 11, or a component that supplies hot air between the drum 3 and the worktable 1.
[0034] As the cylinder 3 is pushed forward, the paper strip 9, glued to the bottom surface of the cylinder 3, enters the receiving platform of the forming system 6 along with it. A paper-cutting component is located near the receiving platform to cut the paper strip 9. During intermittent pauses in the forward movement of the cylinder 3 and the glued paper strip 9, the paper-cutting component cuts the paper strip 9. The cylinder 3, with the fireproof paper adhered to it, is then stacked and assembled into a block on the receiving platform. In this process, the input direction of the paper strip 9 is consistent with the forward direction of the cylinder 3. The input drive of the paper strip 9 can be completed using the existing driving force of the cylinder 3, and the glued bonding of the cylinder 3 and the fireproof paper is completed during the forward movement of the cylinder 3, effectively improving the processing efficiency of assembling the fireproof paper.
[0035] In the example, the paper cutting assembly is equipped with a tube lifting assembly, which includes a top member 14 driven by a first cylinder 13 to reciprocate up and down. When the top member 14 rises, it lifts the adjacent ends 301 of two adjacent tubes 3 on the worktable surface 1 through the paper strip 9. After the two adjacent ends 301 are lifted, they tilt to both sides to form a cutting gap, thereby exposing the paper strip 9 below the tubes 3, making it easier for the paper cutting assembly to cut the paper strip 9 through the cutting gap.
[0036] In the example, the paper cutting assembly includes a knife holder 15 disposed on the workbench 1. A second cylinder 18 and a guide rail 16 are mounted on the knife holder 15 to drive the paper cutter to move. The axial direction of the guide rail 16 is perpendicular to the input direction of the tube 3. The paper cutter 17, which is composed of utility knife blades, reciprocates along the guide rail 16 and inserts into the knife gap to cut the paper strip 9.
[0037] In other embodiments, the paper cutting assembly may be a lifting cutter disposed above the worktable 1, with the cutter axis perpendicular to the input direction of the roll, and the lifting cutter cuts the paper strip when it descends or rises. The cutter may be a serrated cutter.
[0038] As can be seen from the above, this utility model also has the advantages of simple structure and reliable operation. Moreover, it does not require increasing the width of the potting machine, effectively reducing the equipment's footprint; and it has good compatibility with existing potting machine equipment.
[0039] In the example, the worktable 1 is provided with several spaced positioning strips 19. The axial direction of the positioning strips 19 is parallel to the forward direction of the tube array 3. The gap between adjacent positioning strips 19 can accommodate one firework tube, thereby maintaining a corresponding distance between the various firework tubes that make up the tube array. There is a gap between the positioning strips 19 and the worktable 1 for the paper tape 9 to pass through. The upward stroke of the tube array lifting assembly corresponds to the spacing setting. The top piece 14 does not need to lift the positioning strips 19 when it rises. Within the spacing range (such as a spacing of 1 cm), lifting two adjacent ends 301 can form a gap for the blade.
[0040] Example 2: See Appendix Figure 6-7This reflects another specific structure of the present invention. The paper strip 22 is located on the workbench below the bottom surface of the tube array 21. The difference from Embodiment 1 is that there is no positioning strip on the workbench, the sides of each firework tube that make up the tube array 21 abut against each other, there is no gap between the sides of each firework tube, and the sides of each firework tube can also be glued together.
[0041] Example 3: See Appendix Figure 8 This reflects another specific structure of the present invention. The difference from Embodiment 1 is that the paper strip 32 passes over the guide roller 31 behind the feeding and discharging system 30 and enters the worktable 33. The paper strip no longer passes through the strip hole, but instead passes over the end of the worktable 33 and enters the worktable.
[0042] Example 4: See Appendix Figure 9 This reflects another specific structure of the present invention. The difference from Embodiment 1 is that, after the fireproof paper roll 40 is unwound, the paper strip 41 output passes through the gluing mechanism 48 and then wraps around the guide roller 42, entering the top of the drum 43 on the worktable 44; the pressure roller 46, located on the worktable 44, acts on the paper strip 41 to glue it to the top of the drum 43, with the drum 43 positioned between the paper strip 41 and the support roller 45. The lifting cutter 47 cuts the paper strip 41 when it descends. The same objective can be achieved. In other embodiments, the support roller 45 may be omitted, and the drum 43 may slide directly on the worktable 44.
[0043] In other embodiments, the paper strip can also be cut by moving the paper cutter laterally as shown in Example 1.
[0044] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Obviously, many modifications and variations can be made based on the content of this specification. This specification selects and describes these embodiments in detail with reference to the accompanying drawings to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is limited only to the claims and their full scope and equivalents, and not to the specific embodiments disclosed.
