The packaging material is generally referred to in the industry as poster paper. The top poster is adhered to the top of the product, the bottom poster is adhered to the bottom of the product, and the surrounding poster is adhered to the side of the product. In the processing, the bottom poster and the top poster are packaged firstly, then the surrounding poster paper is pasted and packaged around the whole side face of the product, and the surrounding poster paper covers the pasting periphery of the bottom poster paper and the top poster paper on the side wall of the product.

Specifically, the application of the bottom and top panels generally involves two basic steps of sizing and coating: glue is firstly applied to the side walls of the periphery of the product, then the poster paper is coated on the top/bottom of the firework, and the peripheral parts of the bottom poster and the top poster, which are larger than the periphery of the product, are adhered to the side walls of the product.

In the prior art, for example, chinese patent publication No. CN 109204928A discloses "upper and lower paper pasting structures of a full-automatic combined firework packaging machine". The top poster and the bottom poster are also processed by adopting the upper sticker structure 6 and the lower sticker structure 7 to press downwards so that the peripheries of the upper and lower packing paper are completely adhered to the side wall of the firework cylinder, specifically, when the upper packing paper (namely, the top poster) is pressed, the upper pressing plate 64 presses the packing paper, the part of the upper packing paper, which exceeds the firework cylinder, is pressed downwards to the side surface by the downward pressing of the flexible finger 67 and is adhered to the side surface of the firework cylinder by the adhesive coating, the work of the upper packing paper is finished, and the working principle of the lower packing paper (namely, the bottom poster) is the same.

Its drawback lies in, the bight of combination fireworks product is the fillet, when adopting existing equipment to pack, flexible finger 67 is a fixed framework, though framework inner circle four corners is the fillet form, when fixed framework pushed down poster paper cladding, the poster paper of being pressed in fireworks fillet department forms great fold or even arch easily, can not wrap product bight and present the fillet form properly, produces the packing flaw.

For another example, as shown in fig. 1, the frame is composed of four top poster rubber rollers 101 and four mount angle rollers 102 located at four sides of the firework cylinder, when the combined firework extends into the inner ring of the frame, the knife 103 cuts the long strip poster, and the frame covers the cut poster on the firework. The poster paper pressed at the corners of fireworks is easy to form large wrinkles and even bulges, can not properly wrap the corners of products and presents the corners of the fireworks, and causes packaging defects.

Detailed Description

Referring to fig. 2-4, a specific structure of the present invention is shown. The frame body mechanism for combining the firework top and bottom poster coating comprises a frame body consisting of four rotary rollers 3, the two ends of each rotary roller 3 are provided with circular table-shaped end parts 4 with gradually enlarged diameters, and the circular table-shaped end parts 4 of the two adjacent rotary rollers are spliced to enable four corners of an inner ring of the frame body to be in a circular angle shape, so that the circular angle parts 6 of the combined firework 1 correspond to each other. In this example, the outer periphery of the circular truncated cone-shaped end portion 4 is provided with a chamfered portion 5; two adjacent rotary rollers 3 are spliced through the chamfer parts 5, so that four corners of the inner ring of the frame body are in a fillet shape.
