Description

Technical Field

[0001] The utility model relates to a fireworks pot assembling machine, in particular to a machine for assembling pots by mixing cylinders of different specifications. Background Art

[0002] In the prior art, the workflow of a fireworks pot assembly machine is as follows: a material unloading and discharging system unloads multiple fireworks tubes onto a work surface in the required quantity and arranges them in rows; a material pushing device then pushes the multiple fireworks tubes on the work surface into rows parallel to the central axis of the fireworks tube body, and, clamped by the work surface and a conveyor roller assembly, delivers them to a punching and inserting station; a mobile inserting and inserting system completes the punching and inserting process; and then, the sides and tops of the multiple fireworks tubes are glued together to form a tube row. At this point, pushed by the subsequent multiple fireworks tubes, the front tube row enters the forming station in sequence, and the forming system stacks and glues the multiple tube rows together to form a block-shaped whole (a pot). For example, the Chinese invention patent document with authorization publication number CN102538597B discloses a "fireworks assembly machine." To meet consumer demand, fireworks products are constantly being innovated. Current potted flower products mix fireworks tubes of different specifications into pots to enrich the firing effect. For the sake of continuous drawing process and firing effect, the mixed group pots are mixed in units of tube rows. For example, several fireworks tubes with a diameter of R1 form tube row A, and several fireworks tubes with a diameter of R2 form tube row B. Tube rows A and B are mixed and stacked, and glued together to form a block-shaped whole. The mixed stacking can set the number or spacing of tube rows A and B as needed; the specifications of the tube rows are not limited to two, and can be a mixed group pot of tube rows of three, four or even more specifications. Since the existing pot assembling machine can only complete the assembly of tube rows of one specification, such as tube row A, after the punching and inserting process of tube row A is completed, the way for the tube row A of the punching and inserting station to enter the molding station is: the tube row A at the back pushes the tube row A in front to enter the molding station in turn, and the tube row B cannot be inserted therein, so the mixed group pots cannot be carried out in the molding system. Therefore, the same device can only complete the assembly of fireworks tubes of one specification: it cannot meet the requirements of the above-mentioned mixed group pots. To this end, we have developed corresponding mixing and assembling equipment for cylinders of different specifications. For example, the Chinese utility model patent document with authorization publication number CN221037114U discloses "a feeding mechanism of a fireworks assembly machine forming system"; the Chinese utility model patent document with authorization publication number CN218524030U discloses "a cylinder insertion device for fireworks assembly pots"; the Chinese utility model patent document with authorization publication number CN218545460U discloses "a cylinder mixing device for fireworks assembly pots"; the Chinese utility model patent document with authorization publication number CN220103902U discloses "a cylinder mixing device for fireworks assembly pots", etc.

[0003] A drawback of existing mixing equipment is that when mixing three, four, or even more sizes of drums, the drums of different sizes are fed from both sides of the drum machine. For example, for three sizes, the drum machine processes drum A, and drums B and C are fed from both sides of the machine for stacking. However, this requires staff to bypass the drum machine and perform tasks such as adding materials to the drums, performing maintenance, and troubleshooting, increasing the workload. Utility Model Content

[0004] In order to solve the above-mentioned drawbacks, the technical problem to be solved by the present invention is to provide a mixed grouping device for tube rows of three or more specifications, effectively reducing the workload of the staff. In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is a lifting type fireworks tube row mixing device, comprising a working table of a tube row machine, characterized in that it also includes a tube row slide extending below the working table; the tube row slide is provided with a plurality of feed ports, and a step-up storage platform for feeding the tube rows into the tube row slide is provided below each feed port, and a plurality of tube rows are stacked on the step-up storage platform; the tube row slide is provided with a tube row pushing assembly, which pushes the tube rows of the feed port along the tube row slide to the bottom of the working table; the side of the tube row slide below the working table is provided with a tube discharge assembly for pushing the tube rows out of the tube row slide.

[0005] The beneficial effect of the present invention is that a drum slide is provided on one side of the pot assembling machine, and a plurality of step-up material storage platforms can respectively feed drums of different specifications for mixed assembly onto the drum slide through the material inlet. The drum pusher assembly then transports the drums along the drum slide to the bottom of the working table of the pot assembling machine. Finally, the drum discharge assembly pushes the drums out of the drum slide into the forming station to participate in pot assembly, thereby completing the mixed assembly of drums of three or more specifications. The staff who look after the equipment only need to work on one side of the pot assembling machine, and no longer need to go around the pot assembling machine to perform drum material feeding, work maintenance, troubleshooting, etc. on both sides, which effectively reduces the workload.

[0006] In one embodiment, the tube row slide extends below the work surface near the forming station of the pot assembly machine, shortening the pushing stroke of the tube rows that need to be mixed, reducing the size of the equipment, avoiding interference from other factors such as glue, and effectively improving working reliability.

[0007] With the work surface as the front, the tube row in the rear feed port needs to slide over the tube row in the front feed port when passing through the front feed port. If the tube row used for mixed loading is a tube row with affixed release paper, the release paper can prevent the tube row from sliding smoothly due to unevenness. If the tube row is not affixed with release paper, in one embodiment, to avoid the unevenness of the tube row, telescopic slides are provided on both sides of the feed port. The slides extend when the tube row at the rear end passes through, and retract when the step-by-step ascending storage platform of the feed port rises to feed the tube row.

[0008] In one embodiment, a paper input assembly is located on one side of the roll slideway, feeding release paper into the forming station. This assembly includes a paper roll unwinder and a paper cutter for cutting the paper strip. The roll discharge assembly pushes a roll into the forming station, and the paper input assembly feeds release paperboard onto the roll. The release paperboard is positioned between two layers of rolls to prevent uneven stacking of rolls of different specifications due to misaligned concave and convex surfaces.

[0009] In one embodiment, the cylinder row pushing assembly includes a thrust head, and a first driving member is connected and drives the thrust head to reciprocate along the slide rail. Preferably, the first driving member is composed of a first cylinder and a second cylinder, the cylinder body of the first cylinder is installed on the frame, the first cylinder piston rod acts on the slide seat of the slide rail, the cylinder body of the second cylinder is installed on the slide seat, and the second cylinder piston rod acts on the thrust head. Improve work efficiency. In the embodiment of processing the fan-shaped cylinder row, the thrust head has an inclined surface corresponding to the fan-shaped cylinder row side. Preferably, in order to make the equipment meet the mixed processing of upright cylinder row and fan-shaped cylinder row at the same time, the abutment surface of the thrust head and the cylinder row is a movable plate, one end of the movable plate is hinged to the thrust head, and the other end is connected to the telescopic driving member. When processing the fan-shaped cylinder row, the non-hinged end extends out, so that the movable plate swings along the hinged end, forming an inclined surface corresponding to the fan-shaped cylinder row side. When processing the upright cylinder row, the non-hinged end is in a retracted reset state, and the movable plate is a straight surface corresponding to the upright cylinder row side.

[0010] In one embodiment, a glue applicator seat with reciprocating telescopic motion is provided above the side of the tube row slideway corresponding to each feed port, and a plurality of glue applicator heads are provided on the glue applicator seat. When the glue applicator seat is extended, the glue applicator heads apply glue on the tube row. The extended working stroke is set so that the glue application part maintains a reasonable distance from the end of the tube row to avoid glue contamination of the cylinder body or the lead, etc. In the embodiment of processing the fan-shaped tube row, the glue applicator heads are respectively installed on the guide rails, and the fireworks tubes of each guide rail corresponding to the fan-shaped tube row are distributed in a fan shape. Ensure that glue is applied to the fireworks tube. Preferably, a sliding groove is provided on the glue applicator seat, and each glue applicator head is slidably installed in the sliding groove. Each glue applicator head is sleeved in the guide groove of the guide rail, and the fireworks tubes of each guide rail corresponding to the fan-shaped tube row are distributed in a fan shape. When the driving member drives the glue applicator seat to reciprocate and telescopic motion, each glue applicator head slides and changes distance in the sliding groove under the constraint of the guide rail.

[0025] Example 1: See attached Figure 1-4, reflecting a specific structure of the present invention. The lifting type fireworks tube row mixing device includes a work surface 101 of a basin assembly machine and a tube row slide 2. The basin assembly machine processes the first specification A tube row 301, which is sequentially transported to the forming station 102 on the work surface 101. Tube rows of other specifications that need to be mixed include B tube row 302 and C tube row 303. The mixed loading refers to the mixed stacking (basin assembly) of three specifications of tube rows when stacking tube rows at the forming station 102. In this example, each B tube row 302 and C tube row 303 that needs to be mixed has been pasted with isolation paper 305, and the isolation paper of A tube row 301 is fed into the forming station 102 by the paper input assembly and pasted on the tube row. The structure and working principle of the forming station 102 are prior art (such as those described in detail in the literature cited in the background technology) and will not be described in detail.

[0026] In this example, the tube row slide 2 extends below the work surface 101 adjacent to the forming station 102. Adjacent to the forming station 102 can shorten the pushing stroke of the mixed tube row, reduce the volume of the equipment, avoid interference from other factors such as glue, and effectively improve work reliability.

[0027] In the example, the tube row slide 2 is provided with two feed ports, a front feed port 201 and a rear feed port 202. Below each feed port 201, there is a corresponding step-up storage platform 4 for feeding the tube rows into the tube row slide 2. Several tube rows are stacked on the step-up storage platform 4. The tube rows stacked on the two step-up storage platforms 4 can be selected from one of the B tube rows 302 and the C tube rows 303. Each step rises once, so that the top tube row on the step-up storage platform 4 emerges from the feed port to a position where it can be pushed along the tube row slide 2. In other embodiments, there can be a choice of tube rows with more specifications, or more tube row feeding assemblies can be set along the tube row slide 2. The step-up storage platform 4 adopts a screw assembly driven by a stepping motor to realize step-by-step rising and one-time descending and resetting to add the tube rows that need to be mixed.

[0028] The tube row slide 2 is provided with a tube row pushing assembly, which pushes the tube row emerging from the feed port along the tube row slide 2 to the bottom of the work table 101: in the example, the tube row pushing assembly includes a thrust head 5, and the first driving member is connected to and drives the thrust head 5 to reciprocate along the slide rail 501. In the example, the first driving member is composed of a first cylinder 502 and a second cylinder 503, the cylinder body of the first cylinder 502 is mounted on the frame, the piston rod of the first cylinder 502 acts on the slide seat 504 of the slide rail 501, the cylinder body of the second cylinder 503 is mounted on the slide seat 504, and the piston rod of the second cylinder 503 acts on the thrust head 5. The two cylinders work in relay at the same time to improve work efficiency and reduce the equipment footprint.

[0029] In this example, the tube discharge assembly is located on the side of the tube row slide 2 below the work surface 101. This assembly includes a push plate 6 driven by a third cylinder 601. After the thrust head 5 transports the tube row along the tube row slide 2 to below the work surface 101, the push plate 6 pushes the tube row out of the tube row slide 2 and into the forming station 102 for basin assembly.

[0030] In this example, a mixed assembly of three sizes of drums—drum row A 301, drum row B 302, and drum row C 303—can be achieved. Other embodiments could offer a wider range of drum sizes, or incorporate more feed ports and step-up storage platforms along the drum slide 2 to accommodate a wider variety of drums. Staff members tending the equipment can work from just one side of the drum assembler, eliminating the need to traverse both sides of the machine to load drums, perform maintenance, or troubleshoot, effectively reducing workload.

[0031] In this example, a fourth cylinder 701 and a glue applicator 7 are positioned above the side of the tube row slideway 2, corresponding to each feed port. The glue applicator 7 is equipped with several glue heads 702. The fourth cylinder 701 drives the glue applicator 7 to reciprocate and extend. As the glue applicator 7 extends, the glue heads 702 apply glue to each fireworks tube in the tube row, facilitating bonding between the individual tube rows to form a block-like whole (a group of tubes). The operating stroke of the fourth cylinder is set to maintain a reasonable distance between the glue application area and the end of the tube row to prevent glue from contaminating the tube body or the lead wire.

[0032] In this example, to complete the application of release paper to the A-coil row 301, a paper input assembly is provided on one side of the row slideway 2 for feeding release paper into the forming station 102. This assembly includes a paper roll uncoiler and a paper cutter for cutting the paper tape. In this example, the uncoiler drags the paper tape 8 to unwind the paper roll 801, while the cutter 802 of the paper cutter cuts the paper tape 8, either severing it or creating a tear line for easy tearing. When the row discharge assembly pushes an A-coil row 301 into the forming station 102, the paper input assembly feeds release paper onto the row. The release paper is positioned between the two layers of rows, preventing uneven stacking of rows of different specifications due to mismatched concave and convex portions.

[0033] Example 2: See attached Figure 5, reflecting another specific structure of the present utility model. When the tube row in the rear feed port 202 passes through the front feed port 201, it needs to slide over the tube row in the front feed port 201. The tube row used for mixed loading in Example 1 is a tube row that has been pasted with release paper 305. The release paper 305 can avoid the poor sliding caused by the unevenness of the tube row. In this example, the tube row is not pasted with release paper. In order to avoid the poor sliding caused by the unevenness of the tube row, in the example, a fifth cylinder 902 is provided on both sides of the front feed port 905 and the rear feed port 906 to drive a slide 901 that performs telescopic movement. When the tube row 904 is pushed out from the tube row stack of the rear feed port 906, or when the tube row 904 passes through the front feed port 905, the slides 901 on both sides of the two feed ports are extended to cushion under the tube row 904 for it to slide over; when the step-by-step ascending storage platform 903 rises to feed the tube row to the feed port, the slide 901 retracts to avoid interfering with the rise of the tube row.

[0034] A height difference can be set between the slides 901 of the front feed port 905 and the rear feed port 906, so that the tube row passes through the connection part of the front and rear slides 901 more smoothly.

[0035] Example 3: See attached Figure 6-7 , reflecting another specific structure of the present utility model. The difference from Example 1 is that, in this example, other specification tube rows that need to be mixed also include fan-shaped tube row 1001, and thrust head 1002 should have an inclined plane corresponding to the side parallel to fan-shaped tube row 1001, so that fan-shaped tube row 1001 can be reliably pushed along tube row slideway. In the example, in order to make the equipment meet the mixed processing of upright tube row and fan-shaped tube row at the same time, the abutment surface of the thrust head 1002 and the tube row is a movable plate 1003, and the A end 1004 of the movable plate 1003 is hinged on the thrust head 1002, and the B end is hinged on the sixth cylinder 1005 for telescopic movement. When processing fan-shaped tube row 1001, the sixth cylinder 1005 drives the B end to stretch out, so that the movable plate 1003 swings around the A end 1004, forming an inclined plane corresponding to the side parallel to the fan-shaped tube row 1001. When processing the vertical tube row, the B end is in a retracted reset state, and the movable plate 1003 is a straight surface parallel to the side surface of the vertical tube row.

[0036] In this example, the gluing base 1006 is provided with a sliding groove 1007. The bottom end of each gluing head 1008 slides into this groove, and the middle portion of each gluing head 1008 is sheathed in a guide groove of a guide rail 1009. Each guide rail corresponds to the fan-shaped arrangement of the fireworks tubes in the fan-shaped row. When the seventh cylinder 1010 drives the gluing base 1006 to reciprocate and extend, each gluing head 1008 slides and varies its pitch within the sliding groove 1007, constrained by the guide rail 1009, ensuring that glue is applied to the fireworks tubes in the fan-shaped row.

[0037] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the present invention to the specific implementation methods described. Obviously, many modifications and changes can be made based on the contents of this specification.

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 violating the connotation of the present invention. Therefore, the present invention is only limited by the claims and their full scope and equivalents, and is not limited by the specific embodiments disclosed.
