Description

Technical Field

[0001] The utility model relates to a device for covering a top sparkler and a bottom sparkler of a firework onto the firework. Background Art

[0002] After the combination fireworks products are formed, they need to be packaged in a cover, that is, plastic, paper, etc. are pasted on the surface of the product for closed packaging. This packaging material is generally called paper in the industry. The top paper pasted on the top of the product is the top paper, the bottom paper pasted on the bottom of the product is the bottom paper, and the side paper pasted on the side of the product is the surrounding paper. During processing, the bottom paper and the top paper are packaged first, and then the surrounding paper is pasted and packaged around the entire side of the product. The surrounding paper covers the surrounding area of ​​the bottom paper and the top paper on the side wall of the product.

[0003] Specifically, the pasting of bottom and top posters generally includes two basic steps: gluing and wrapping. First, glue is applied to the four side walls of the product, and then the poster paper is wrapped on the top / bottom of the fireworks. The parts of the bottom and top posters that are larger than the periphery of the product are pasted on the side walls of the product.

[0004] In the prior art, the Chinese utility model patent document with the authorization announcement number CN 218368566 U discloses "a frame mechanism for covering the top and bottom of combined fireworks". It includes a frame composed of four rollers, and the two ends of the rollers have truncated cone-shaped ends with gradually increasing diameters. The truncated cone-shaped ends of two adjacent rollers are spliced ​​so that the four corners of the inner circle of the frame are rounded. With the above technical solution, when the frame presses the paper to make it close to the combined fireworks, the overall angular velocity of the roller body is the same when it rotates, but the linear velocity of the truncated cone-shaped end increases with the increase of the diameter; the rounded corners of the inner circle of the frame formed by the truncated cone-shaped end can pull the paper to make it appear as fine wrinkles and stick to the rounded corners of the combined fireworks during rotation, avoiding large wrinkles and protrusions, effectively improving the covering effect of the rounded corners of the combined fireworks, and improving the packaging quality. The utility model refers to the above utility model patent document in its entirety.

[0005] The disadvantage is that the existing frame structure is only suitable for covering the bottom of combination fireworks with a rounded quadrilateral cross section. As the combination fireworks products are updated and iterated, their shapes are more diverse, and their cross-sectional shapes can also be other rounded polygons, such as triangles, pentagons, hexagons, heptagons, octagons or other rounded polygons with more sides. The existing frame structure composed of four rollers cannot be used for covering the bottom of these combination fireworks. Utility Model Content

[0006] In order to solve the above-mentioned drawbacks, the technical problem to be solved by the utility model is to provide a frame for covering the top and bottom of combined fireworks, which is suitable for improving the rounded corner covering effect of combined fireworks of various shapes. In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is a frame for covering the combined fireworks, including a roller, and the two ends of the roller have truncated cone-shaped ends with gradually increasing diameters; it is characterized in that the cross-sectional shape of the combined fireworks is selected from rounded triangles, rounded pentagons, rounded hexagons, rounded heptagons, and rounded octagons, and the number of the rollers is equal to the number of sides of the cross-sectional shape of the combined fireworks, and the number of the rollers is selected from 3 or 5 to 8; each roller is spliced ​​and combined into a closed-loop frame, and the shape of the frame is set corresponding to the cross-sectional shape of the combined fireworks; the ends of two adjacent rollers are spliced ​​so that the splicing part of the inner circle of the frame is rounded.

[0007] The beneficial effect of the utility model is that the above technical solution can still effectively improve the rounded corner covering effect of the combined fireworks; at the same time, the frame structure is a closed-loop structure composed of 3 or 5 to 8 rollers, which can adapt to the top and bottom covering processing of combined fireworks of different shapes.

[0011] Figure 2 This is a schematic diagram of the principle structure of the frame of Example 2;

[0012] Figure 3Schematic diagram of the principle structure of the frame of Example 3. DETAILED DESCRIPTION

[0013] Example 1: See attached Figure 1 , reflecting a specific structure of the utility model. The frame covering the combined fireworks paper includes three rollers 101, and both ends of the rollers 101 have truncated cone-shaped ends 102 with gradually increasing diameters. The cross-sectional shape of the combined fireworks is a rounded triangle with three sides, so the number of rollers 101 is the corresponding three, and the two are equal. The three rollers 101 are spliced ​​and combined into a closed-loop frame, and the shape of the frame is set corresponding to the rounded triangle shape of the cross-sectional shape of the combined fireworks; the truncated cone-shaped ends 102 of two adjacent rollers are spliced ​​so that the splicing part of the inner circle of the frame is rounded.

[0014] In the example, the truncated cone-shaped ends 102 of the three rollers 101 are spliced ​​together so that the triangular spliced ​​parts of the inner circle of the frame remain rounded. The roller bodies of the three rollers 101 rotate at the same overall angular velocity, but the linear velocity of the truncated cone-shaped ends increases with the increase of the diameter. The rounded corners of the inner circle can pull the corresponding parts of the top and bottom strokes to be distributed more evenly during rotation, so that they form a combination of small wrinkles and stick to the rounded corners of the combined fireworks, which can also avoid the generation of large wrinkles or bulges. Therefore, the utility model can effectively improve the covering effect of the rounded corners of the combined fireworks.

[0015] Example 2: See attached Figure 2 , reflecting another specific structure of the utility model. The difference from Example 1 is that, in this example, the cross-sectional shape of the combined fireworks is a rounded pentagon with five sides, so the number of rollers 201 is correspondingly five. The five rollers 201 are spliced ​​and combined into a closed-loop frame, and the shape of the frame is set corresponding to the shape of the rounded pentagon of the cross-sectional shape of the combined fireworks; the truncated cone ends of two adjacent rollers are spliced ​​so that the splicing part of the inner circle of the frame is rounded. It can also effectively achieve the purpose of the invention.

[0016] Example 3: See attached Figure 3 , reflecting another specific structure of the utility model. The difference from Example 1 is that, in this example, the cross-sectional shape of the combined fireworks is a rounded hexagon with six sides, so the number of rollers 301 is six. The six rollers 301 are spliced ​​and combined into a closed-loop frame, and the shape of the frame is set corresponding to the rounded hexagonal shape of the cross-sectional shape of the combined fireworks; the truncated cone ends of two adjacent rollers are spliced ​​so that the splicing part of the inner circle of the frame is rounded. It can also effectively achieve the purpose of the invention.

[0017] In other embodiments, the cross-sectional shape of the combined fireworks is a rounded heptagon or a rounded octagon, and the number of rollers is seven or eight. The rest is the same as in Embodiment 1, and the purpose of the invention can also be effectively achieved. No further details will be given.

[0018] The embodiments of the utility model disclosed above are only used to help illustrate 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. This specification selects and describes these embodiments in detail in conjunction with the accompanying drawings in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can understand and use the utility model well. 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.
