[0003] The conveying assembly of the device includes a tray, and the pre-cut sieves are stacked in the tray for standby; the lifting mobile suction cup delivers the sieves 7 in the tray 601 to the conveyor belt 607, and the conveyor belt 607 delivers the sieves to the entrance 616 of the coating station in an upright state. The conveyor belt 607 includes a parallel part, a corner part and a descending part. The sieves follow the conveyor belt through the corner part and fall due to their own weight. The end of the parallel part of the conveyor belt connects to the entrance 616 of the coating station below through the paper passing gap 609 of the corner part; the conveyor belt 607 of the descending part is provided with a plurality of paper protection lifting and retracting rods 613, which extend to escort the sieves when the sieves are descending, and retract after the sieves are in place. The conveyor belt 607 can also be provided with a plurality of sieve pressing wheels 612.

[0004] The disadvantage of the existing device is that when the siege passes through the corner of the conveyor belt and enters the descending part and falls to the entrance of the coating station, it may deviate to the left and right, affecting the coating quality of the siege; and in order to ensure that the siege falls smoothly due to its own weight, it is necessary to set up escort components such as the paper passing gap 609, the paper protection lifting and retracting rod 613, and the siege pressure wheel 612, which makes the mechanism complicated.

[0023] See attached Figure 1-9 , reflecting a specific structure of the utility model. The conveying mechanism of the combined fireworks cover device includes a tray and a lifting mobile suction cup 6, and the pre-cut surrounds 5 are stacked in the tray for standby. In the example, there are four trays, including a first tray 701, a second tray 702, a third tray 703, and a fourth tray 704, and pre-cut surrounds 5 are stacked in each tray. The patterns or colors printed on the surrounds 5 in each tray can be different, so that the lifting mobile suction cup 6 can call different surrounds 5 as needed to meet the packaging requirements of different combined fireworks 2.

[0024] In the example, the conveying mechanism for the siege ball includes two meshing rotary transmission mechanisms arranged side by side on the left and right, namely, chain transmission mechanisms, and a plurality of accompanying clamps 8 are fixedly mounted on the two rotary chains. A bracket 4 for supporting the middle part of the siege ball 5 can be provided between the two rotary chains.

[0025] Each chain transmission mechanism includes a parallel portion 101, a corner portion 102 and a descending portion 103. When the portable fixture 8 in the open state moves to the parallel portion 101 close to the end of the tray, the movable suction cup 6 sends the siege 5 in the tray to the open portable fixture 8, and the portable fixture 8 is closed; then, when the closed portable fixture 8 clamps the siege 5 and passes through the corner portion 102 and moves to the descending portion, the portable fixture 8 opens and places the siege 5 on the entrance 3 of the coating station in an upright state, and the siege of the combined fireworks 2 is wrapped. The wrapping work is disclosed in the Chinese invention patent document with application publication number CN 115593736A, "A Combination Fireworks Skinning Device", which will not be repeated.

[0026] In the example, the accompanying clamp 8 is an elastic self-locking clamp composed of a fixed clamp part 801 and a movable clamp part 802; the fixed clamp part 801 is fixed on the rotating chain, the movable clamp part 802 is provided with an operating handle 803, and the working end of the operating handle 803 is provided with a contact ball 804 to reduce friction.

[0027] An opening and closing assembly is provided near the rotary chain, and the opening and closing assembly is provided corresponding to the operating handle 803; the opening and closing assembly includes a closing assembly 9 located in the parallel part 101 and an opening assembly 10 located in the descending part 103: in the parallel part 101, after the encircling piece 5 is sent to the accompanying fixture 8 in the open state, the closing assembly 9 closes the accompanying fixture 8 to clamp the encircling piece 5 through the operating handle 803; when the accompanying fixture 8 clamps the encircling piece 5 and runs to the descending part, the opening assembly 10 opens the accompanying fixture 8 through the operating handle 803 to release the encircling piece 5 and place it on the coating station entrance 3. Each accompanying fixture 8 can share a set of opening and closing assemblies to simplify the structure of each accompanying fixture 8; at the same time, it can also ensure that the position and timing of closing / opening of the accompanying fixture 8 are accurate, which is convenient for reliable coordination of other components.

[0028] In the example, the portable clamp 8 is an elastic self-locking clamp: after the opening and closing assembly closes / opens the portable clamp 8 through the operating handle 803 each time, the portable clamp 8 can maintain the closed / open state formed after the operation through the internal spring and the locking mechanism, such as the switch position locking of an electrical switch.

[0029] In the example, the opening and closing component includes an operating claw 1002 driven to rotate by a cylinder 1001, and the operating claw 1002 is arranged corresponding to the operating handle 803. In the standby state, the cylinder 1001 drives the operating claw 1002 to rotate to the avoidance position without hindering the passage of the operating handle 803; after the operating handle 803 runs to the working position with the rotating chain, the cylinder 1001 drives the operating claw 1002 to rotate to the operating position, and the operating claw 1002 abuts against the working end of the operating handle 803, and drives the movable clamp part 802 to rotate around the rotating axis through the operating handle 803, thereby opening / closing the accompanying clamp 8.

[0030] By adopting the above scheme, the two accompanying clamps 8 correspondingly arranged on the two rotary chains clamp the two sides of each sieve 5 and convey it to the entrance 3 of the coating station and then release it, ensuring that the front, back, left and right positions of the sieve 5 are not offset, and the meshing rotary transmission ensures the accurate conveying stroke of the sieve; at the same time, the fixed clamping and conveying are reliable, especially in the process of the sieve 5 passing through the corner part 102 and entering the descending part 103 and falling to the entrance 3 of the coating station, there is no need to set other escort components such as paper passing gaps, paper protection lifting and retracting rods, sieve pressure wheels, etc., to ensure the smoothness of the entire conveying stroke of the sieve, thereby effectively streamlining the equipment structure.

[0031] The above disclosed embodiments of the utility model are only used to help explain the utility model. The embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. For example:

[0032] In other embodiments, the meshing rotary transmission mechanism may be a synchronous belt transmission mechanism, and the rotary belt is a synchronous belt, which also ensures that the conveying stroke of the surrounding ball is accurate and does not affect the realization of the purpose of the invention.

[0033] In other embodiments, the portable clamp may be an automatic clamp that is automatically opened / closed by an electric signal, and opened / closed in time according to the signal or instruction, which does not affect the realization of the purpose of the invention.

[0034] This specification selects and describes these embodiments in detail in conjunction with the drawings in order to better explain the principles and practical applications of the utility model, so that those skilled in the art can better understand and use the utility model. However, the utility model 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 utility model. Therefore, the utility model is only limited by the claims and their full scope and equivalents, and is not limited by the specific embodiments disclosed.
