The top poster and the bottom poster coating unit 3 comprise a side edge packaging mechanism and a front and back packaging mechanism.

The side edge packaging mechanism comprises a bottom conveyor belt 306 and a top conveyor belt 316 which are arranged in an up-and-down symmetrical mode, and the tail end of the bottom conveyor belt 306 is connected with the auxiliary conveyor belt 501.

The elongated bottom poster 300 drawn from the roll is guided by the set of guide rollers to lay flat on and move with the bottom conveyor belt 306, and the elongated top poster 301 drawn from the roll is laid flat on and move with the top conveyor belt 316.

The combined fireworks 6 on the feeding conveyor belt 1 are pushed to the running distance conveyor belt 309 one by the transverse pushing cylinder 601 according to a set time interval, so that the combined fireworks 6 are arranged on the distance conveyor belt 309 according to a set front-back distance and then enter the position between the bottom conveyor belt 306 and the top conveyor belt 316 in sequence; under the bidirectional action of the carrier roller 302 of the bottom conveyor belt and the press roller 315 of the top conveyor belt, the combined fireworks 6 are embedded between the bottom poster paper 300 and the top poster paper 301.

The widths of the bottom poster 300 and the top poster 301 are larger than the width of the combined firework 6, and the left and right sides of the bottom poster 300 and the top poster 301 are provided with poster side edges exposed outside the combined firework 6.

The left and right sides of the bottom conveyor belt 306 are provided with longitudinal glue applying nozzles 303 for applying glue to the above mentioned poster side edges of the bottom poster 300; the top conveyor belt 316 is provided on both left and right sides with longitudinal glue application nozzles 313 for applying glue to the above-mentioned poster side edges of the top poster 301.

In this example, the paper folding guide plates 326 are provided on both left and right sides of the bottom conveyor belt 306 and the top conveyor belt 316, respectively, and referring to fig. 6, 7, and 8, the paper folding guide plates 326 are twisted into the upright portions 326B at the tail ends by the horizontal portions 326A at the head ends, the horizontal portions 326A are attached to the conveyor belts, the upright portions 326B are attached to the side surfaces of the combined fireworks 6, and the horizontal portions 326A of the paper folding guide plates 326 on both sides sandwich the side surfaces of the combined fireworks 6. So that the side edges of the top and bottom poster paper in the forward moving process are bent from a flat state to a vertical state and are attached to the side wall of the combined firework 6.

The bottom conveyor belt 306 drives the bottom poster paper 300 and the combined fireworks 6 to synchronously move forwards, and the longitudinal glue applying nozzle 303 finishes longitudinal glue applying on the side edge during the movement of the bottom poster paper 300; under the action of the two lower paper folding guide plates 326, the side edges of the bottom poster paper 300 are folded upwards and adhered to the lower parts of the left and right side walls of the combined firework 6; the top conveyor belt 316 drives the top poster 301 and the combined fireworks 6 to move forwards synchronously, and the longitudinal glue applying nozzle 313 finishes longitudinal glue applying on the side edge during the movement of the top poster 301; under the action of the upper two paper folding guide plates 326, the side edges of the top poster paper 301 are folded downwards and adhered to the upper parts of the left and right side walls of the combined firework 6.

In order to adapt to the packaging processing of products with various specifications, a lifting guide post 317 is arranged between the bottom conveyor belt 306 and the top conveyor belt 316, and when combined fireworks 6 with different heights are processed, the vertical distance between the two can be conveniently adjusted along the lifting guide post 317. The left-right distance between the two paper folding guide plates 326 at the upper part or the lower part can also be adjusted by adjusting the installation and fixing positions of the paper folding guide plates so as to adapt to the processing of combined fireworks with different left-right widths.

The front and rear packaging mechanisms comprise a movable transverse glue applicator, taking bottom poster paper as an example: the mobile transverse glue applicator comprises a transverse glue cylinder 328 driving a glue applying nozzle 304 which reciprocates left and right to apply glue to the bottom poster paper 300 in a front-rear spacing area (h-h area shown in fig. 7, the same applies below) of the two combined fireworks 6. The transverse sizing of the top poster paper 301 is similar and will not be described in further detail.

The front and back packaging mechanism further comprises an upper roller 319 and a lower roller 323 which are symmetrically arranged up and down, the lower roller 323 is arranged between the bottom conveyor belt 306 and the auxiliary conveyor belt 501, the upper roller 319 is arranged at the tail end of the top conveyor belt 316, a compactor for combined fireworks 6 is arranged beside the upper roller 319, and the compactor comprises a compacting plate 322 driven by a compacting cylinder 320.

After passing through the paper folding guide plate 326, the top poster 301, the bottom poster 300 and the combined fireworks 6 thereof continue to synchronously move forwards; when the first combined firework 6 moves to the auxiliary conveyor belt 501, the second combined firework 6 is positioned on the bottom conveyor belt 306, and the front-back spacing areas of the two combined fireworks 6 correspond to the positions between the upper roller 319 and the lower roller 323, the top and bottom conveyor belts are paused (at the moment, the front-back spacing areas of the top poster 301 and the bottom poster 300 are glued by the movable transverse glue applicator), the pressing plate 322 driven by the pressing cylinder 320 acts to press the first combined firework 6 and the top poster 301 thereof, and at the moment, the second combined firework 6 and the corresponding top and bottom poster thereof are still embedded between the bottom conveyor belt 306 and the top conveyor belt 316; at this time, the upper roller 319 and the lower roller 323 operate:

the lower roller 323 comprises a lifting lower bracket 329, a lower paper cutting knife 325 facing the bottom poster 300 is arranged on the lifting lower bracket 329, and a front lower sealing roller 331 and a rear lower sealing roller 330 are arranged below the lower paper cutting knife 325.

In order to ensure the compatibility of the equipment and process the combined fireworks with smaller product size, the space between the bottom conveyor 306 and the auxiliary conveyor 501 needs to be reduced as much as possible, and the small combined fireworks 6 can smoothly pass through the space. Meanwhile, the consumption of poster paper is effectively reduced. In this example (see fig. 9 and 10), the left and right sides of the lower roller 323 are provided with direction-changing guide grooves 332, and the width of the direction-changing guide grooves 332 is gradually enlarged from bottom to top. The rotating shafts 337 at the two ends of the front and rear

lower sealing rollers

331 and 330 pass through the oblong holes 336 of the lifting support 329, and the ends of the rotating shafts 337 are mounted in the direction-changing guide grooves 332 through bearings 334. The front lower sealing roller 331 and the rear lower sealing roller 330 are distributed up and down; one torsion arm of the torsion spring 335 acts on the front lower sealing roller 331 to push the roller body forward, and the other torsion arm acts on the rear lower sealing roller 330 to push the roller body rearward.

In a standby state, the front lower sealing roller 331 and the rear lower sealing roller 330 which are lowered in the spacing area are restrained by the direction-changing guide groove 332 to be in a parallel state up and down, so that the distance of the spacing area can be minimized, and the torsion spring 335 is compressed and deformed.

When the paper feeding device works, the rolling air cylinder 333 pushes the lifting lower support 329 to ascend, and the lower paper cutter 325 positioned at the center line position of the front and rear spacing areas ascends towards the bottom poster paper 300 and cuts off the bottom poster paper 300; the two roller bodies of the front lower sealing roller 331 and the rear lower sealing roller 330 which rise along with the two roller bodies leave the spacing area, and along with the expansion of the groove width of the turning guide groove 332, the torsion spring 335 without restraint pushes the front lower sealing roller 331 to move forwards along the long circular hole 336, so that the roller surfaces of the front lower sealing roller 331 are attached to and pressed on the rear side surface of the first combined firework 6 to roll and rise, and the front half part of the fracture of the bottom poster paper 300 is attached to the lower part of the rear side surface of the first combined firework 6;

the torsion spring 335 simultaneously pushes the rear lower sealing roller 330 to displace towards the rear along the oblong hole 336, so that the rear lower sealing roller 330 sticks the rear half part of the fracture of the bottom poster paper 300 to the lower part of the front side surface of the second combined firework 6;

the lift down bracket 329 is then lowered to reset to the standby state.

The upper lifting support of the upper roller 319 descends, the upper paper cutter descends towards the top poster 301 and cuts the top poster 301, then the front upper sealing roller which rolls downwards sticks the front half part of the fracture of the top poster 301 to the upper part of the rear side of the first combined firework, and the rear lower sealing roller which rolls downwards sticks the rear half part of the fracture of the bottom poster 301 to the upper part of the front side of the second combined firework. The upper roller 319 and the lower roller 323 have the same structure, but are symmetrically disposed up and down, and the structure and the operation flow thereof are not described in detail.

The upper roller 319 and the lower roller 323 are generally operated simultaneously to improve efficiency. However, the height of some small-sized products is not enough, and the simultaneous action may cause the collision of the cutters of the two rollers, and in this case, the two rollers can also act in time-staggered and sequential modes.

As can be seen from the above description, the upper roller and the lower roller may not have the above structure in other embodiments, regardless of the processing of the combined firework with a smaller product size. For example:

the front lower sealing roller, the rear lower sealing roller, the front upper sealing roller and the rear upper sealing roller do not have position change in the front-rear direction in the lifting process, and each roller body is provided with an elastic roller surface or an elastic roller body made of elastic materials such as rubber, plastics and sponge. The front and back fit relation between the roller surface and the side surface of the combined firework can adopt transition fit or interference fit, so that the roller surface is elastically attached to and pressed on the front side surface or the back side surface of the combined firework in the ascending or descending process and rolls.

As can be seen from the above, the top and bottom poster coating unit 3 can automatically complete the top and bottom poster packaging process of the combined firework product; the action is simple, the work is reliable, the efficiency is higher, can be fit for the packing work of the combination fireworks of various specifications.

The combined fireworks 6 which are finished to be covered by the top and bottom signs in the top and bottom sign covering unit 3 are sent to the surrounding sign wrapping unit 5 by the auxiliary conveyor belt 501. Enclose and attract parcel unit 5 promptly an automatic parcel device that combination fireworks enclosed and attract.

As shown in fig. 14, in this example, the cutting knife 539 of the cutting mechanism and the glue applying nozzle 538 of the glue applying mechanism are integrated on the coating and cutting slider 536, and the coating and cutting slider 536 is provided with an extending cylinder 513 for driving the cutting knife 539 and the glue applying nozzle 538 to extend/retract toward the poster paper 512. The coating and cutting cylinder 527 drives the coating and cutting slider 536 to reciprocate along the coating and cutting guide 534 in the width direction of the poster paper.

The driving roller 508 and the driven roller 511 drive the surrounding poster paper 512 to pass through between the cutter supporting plate 510 and the cutter 539, and pause according to the signal of the color mark sensor 509; the paper cutting pressing arm 516 is driven by the paper cutting pressing arm air cylinder 531 to press the surrounding poster paper 512 to be in a tensioning state; the cutter 539 extends out and ascends to cut off the surrounding poster paper 512; meanwhile, the glue coating nozzle 538 synchronously rises to finish the glue coating of the areas on the two sides of the fracture of the surrounding poster paper; the paper blocking piece, the coated paper blocking grid 533, rises synchronously to protect the surrounding poster paper from disorder; then, the cutter 539 and the glue coating nozzle 538 retract first, the front end of the fractured surrounding poster 512 enters the fixed conveying belt 517 through the coating and cutting paper blocking grid 533 and then is sucked, and the cutter 539, the glue coating nozzle 538 and the coating and cutting paper blocking grid 533 descend again; the surrounding poster 512 in front of the break continues to advance. One action accomplishes both the cutting and sizing operations.

In this example, the enclosing and conveying belt comprises a fixed conveying belt 517 and a swinging conveying belt 518 which are connected back and forth, the fixed conveying belt 517 and the swinging conveying belt 518 are both provided with a vacuum adsorption cavity 519, and the vacuum adsorption cavity 519 is connected with a vacuum generating mechanism through an air suction roller 521, an air suction opening 524 and an air suction pipe 528. The cut poster paper 512 is laid flat on the poster conveyor belt by suction. The enclosing conveying belt and the traction roller set synchronously and intermittently operate.

The swing conveyer belt 518 is hinged at the end of the fixed conveyer belt 517 by using the suction roller shaft 522 as a hinge point, and the hinged end of the swing conveyer belt 518 is connected with the fixed conveyer belt 517 to continuously convey the poster paper 512.

The oscillating conveyor belt cylinder 530 drives the oscillating conveyor belt 518 to oscillate through the oscillating conveyor belt gear shaft 523 and the oscillating conveyor belt gear 529. Three functions are as follows: firstly, swinging the conveyer belt 518 to drive the poster paper attaching roller 506 to approach the combined firework 6, and pressing and attaching the end part of the poster paper 512 on the combined firework 6; secondly, in the rotation process of the combined firework 6, the pressure provided by the swing conveyer belt cylinder 530 plays a role similar to that of a gas spring to form elastic pressure, so that the poster paper attaching roller 506 is always pressed on the side wall of the combined firework 6, and the poster paper attaching roller and the combined firework 6 are not separated from each other due to the rotation of the combined firework 6. (because the combined fireworks rotate, except the cylindrical combined fireworks, the combined fireworks in the shapes of a cube, a cuboid, a hexagon and the like have radial size change of the side wall and the center in the rotation); thirdly, the swing conveyer belt 518 drives the poster paper attaching roller 506 to leave the combined firework 6 to reset, so that the end parts of the combined firework 6 and the poster paper 512 can smoothly reach the preset station.

Taking a square combined firework with the specification of 30cm multiplied by 30cm as an example, the length of the corresponding surrounding poster paper is 1.2m +. This requires that the total length of the fixed 517 and oscillating 518 conveyor belts be at least 1.2m + to avoid waiting for the package to be fed and cut while rotating. Considering the smoothness of the operation of the device, the total length should satisfy the requirement of 1.2m + x 2 or even 1.2m + x 3, which results in a wider occupied area of the device, and for this reason, the hinged end of the oscillating conveyor 518 is taken as a turning point in this example, and the fixed conveyor 517 and the oscillating conveyor 518 are folded to reduce the volume of the device.

The poster paper attaching roller 506 is provided corresponding to the combined firework 6 on the rotating lower support plate 551, and in this example, the poster paper attaching roller 506 has an elastic roller surface. Such as a roller surface or the whole roller body made of elastic materials such as rubber, plastic, sponge and the like. During the rotation of the combined fireworks 6 on the rotating lower support plate 551, the elastic roller surface is attached and pressed on the side surface of the combined fireworks 6 and forms rolling.

In this example, the poster attaching roller 506 is provided at the free end of the swing conveyor 518, and the poster attaching roller 506 reciprocates toward the combined fireworks 6 on the rotating lower plate 551 in accordance with the swing of the swing conveyor 518.

The overall workflow of the enclosure wrapping unit 5 is summarized as follows:

the rotary lower supporting plate 551 and the rotary upper pressing plate 550 clamp the combined fireworks 6 between the rotary lower supporting plate 551 and the rotary upper pressing plate 550; the surrounding poster paper 512 led out by unwinding the surrounding poster paper roll is drawn to the surrounding poster conveyor belt through a drawing roller group; in the operation intermittence period of the traction roller set and the surrounding and covering conveying belt, the cutting mechanism acts to cut the surrounding and covering paper 512, and the gluing mechanism acts to glue; the surrounding poster paper 512 moves forwards under the combined action of the traction roller group and the surrounding poster conveying belt, when the front end of the surrounding poster paper 512 is conveyed to the poster paper attaching roller 506, the poster paper attaching roller 506 moves towards the combined firework 6, and the front end of the glued surrounding poster paper 512 is pressed and attached to the side wall of the combined firework 6; with the rotation of the rotating lower supporting plate 551, the surrounding poster paper 512 cut according to the set length is wrapped around the side wall of the combined firework 6; the poster paper attaching roller 506 presses and attaches the rear end of the glued poster paper 512 to the front end to achieve the jointing. Thus completing the packaging of the poster paper of the combined fireworks.

The surrounding and covering unit 5 can ensure that the running conditions of the surrounding and covering paper before and after cutting are in a precise controllable state, reliably and automatically realize the rotary covering of the surrounding and covering paper, and ensure that the covering quality meets the requirements; the device has simple action, smooth matching, relatively simple structure and high working efficiency; can be suitable for the packaging work of combined fireworks with various specifications.

In other embodiments, the poster paper attaching roller can also be independently arranged at a position close to the free end of the swinging conveying belt instead of the free end of the swinging conveying belt, and is driven by other driving mechanisms to reciprocate towards the combined fireworks, so that the functional function of the poster paper attaching roller can be realized. But the operational reliability may be reduced compared to the present example.
