one side of the width direction of the protruding pressing block covers a cold seal paper area corresponding to one side of the product, the other side of the width direction of the protruding pressing block is retracted into the cold seal paper area on the other side of the product, and a taking position is arranged in the cold seal paper area on the other side of the width direction of the product;

the outer side of the upper layer of cold seal paper corresponding to the position area of the opening is folded inwards to form a first inward fold; the outer side of the lower layer cold seal paper corresponding to the opening taking position area is folded inwards to form a second inward fold, so that the product after subsequent punching and the corresponding cold seal paper can be conveniently and integrally taken out;

the outer side end of the first inward fold is retracted relative to the outer side end of the second inward fold, so that the front side and the back side of the product are convenient to distinguish;

the axial ends of the upper pressure attaching roller and the lower pressure attaching roller are provided with mutually meshed transmission teeth, so that the pressure attaching roller set can synchronously operate, and a pair of raised pressing blocks of the pressure attaching roller set can synchronously press and attach the upper layer cold seal paper and the lower layer cold seal paper;

the logo corresponding to the product is printed on the upper layer of cold seal paper in advance, so that the product does not need to be pressed again after being rolled by cold seal paper.

After adopting above-mentioned technical scheme, attach the roller at last pressure, it sets up protruding pressfitting piece corresponding to product edge region to attach the roller down to press, the product region is done the fretwork and is dodged the position and handle, the pressfitting piece carries out the pressfitting cold seal to product all around cold seal paper and avoids contacting the product when the roller sword rotates, it carries out the pressfitting cold seal to cold seal paper through increasing protruding pressfitting piece at roller sword product edge region, and dig the position of dodging to the product region on the pressfitting piece, cause the product to warp when avoiding the pressfitting, it makes the edge of product can not warp, satisfy user's demand.

the names corresponding to the sequence numbers in the figure are as follows:

the product comprises a product 10, lower-layer cold seal paper 20, upper-layer cold seal paper 30, an upper pressing and attaching roller 40, a lower pressing and attaching roller 50, a protruding pressing and combining block 60, a cold seal pressing and attaching edge 70, a mouth taking position 80, a first inward fold 81, a second inward fold 82, a spacing distance L and a spacing gap H.

Detailed Description

A partial pressing process of cold seal paper is shown in figure 1: the products 10 are sequentially arranged on the lower layer cold seal paper 20 at intervals, the lower layer cold seal paper 20 carries the products 10 to be conveyed along the advancing direction, then the upper layer cold seal paper 30 is covered on the lower layer cold seal paper 20 through an attaching roller set, the attaching roller set comprises an upper attaching roller 40 and a lower attaching roller 50, the peripheries of the upper attaching roller 40 and the lower attaching roller 50, which correspond to the product 10 area, are provided with profiling convex pressing blocks 60, and the cold seal attaching edges 70 which are covered on the product periphery are formed after the upper layer cold seal paper 30 and the lower layer cold seal paper 20 are pressed by the attaching roller set.

The outer peripheral area formed by the convex pressing block 60 is the shape of the product after expanding outward by a spacing distance L of 2.5mm, and the 2.5mm packaging margin ensures that the upper pressing roller 40 and the lower pressing roller 50 do not press and attach to the product 10 when closing the corresponding cold seal paper.

In the specific embodiment: six groups of corresponding convex pressing blocks 60 are annularly distributed at axial positions of the peripheries of the outer rings of the upper pressing roller 40 and the lower pressing roller 50, which correspond to the product pressing area; each set of convex pressing blocks 50 is in a closed rectangular shape; and 2mm interval gaps H are arranged between adjacent protruding pressing blocks of the annular cloth of the upper pressing roller 40 and the lower pressing roller 50, so that the subsequent cutting and distinguishing of each group of products are ensured.

One side of the protruding pressing block 60 in the width direction covers a cold seal paper area corresponding to one side of the product 10, the other side of the protruding pressing block 60 in the width direction is retracted into the cold seal paper area on the other side of the product 10, and a take-out position 80 is arranged in the cold seal paper area on the other side of the product in the width direction;

the outer side of the upper layer cold seal paper 20 corresponding to the opening position area is folded inwards to form a first inward fold 81; the outer side of the lower layer cold seal paper 30 corresponding to the area of the opening taking position is folded inwards to form a second inward fold 82, so that the product after subsequent punching and the corresponding cold seal paper can be conveniently and integrally taken out;
