It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" or "in communication with" another element, it can be directly connected to the other element or intervening elements may also be present.

Referring to fig. 3, a method for manufacturing a stamping plate roller according to an embodiment includes the following steps:

step S120: the first connecting end 210 and the main body portion 220 of the embossing plate 20 are fixed to the roll 10.

Specifically, referring to fig. 4, the molding plate 20 can be divided into a first connecting end 210, a main body portion 220 and a second connecting end 230, wherein an end 211 of the first connecting end 210 is a plane, and the length of the molding plate 20 is greater than the circumference length of the roll 10 in the circumferential direction of the roll 10. When manufacturing the embossing plate roller, firstly, the end 211 of the first connecting end 210 is arranged in a coplanar manner with the central axis of the roller 10, the first connecting end 210 is fixed on the roller 10 after being determined, and the embossing plate 20 is attached around the circumferential surface of the roller 10, so that the main body part 220 of the embossing plate 20 is closely attached to the circumferential surface of the roller 10.

In some embodiments, before step S120, step S110 is further included: the first connecting end 210 of the molded plate 20 is cut.

Specifically, according to the design picture and text of the molded plate, the first connecting end 210 of the molded plate 20 is cut according to the bleeding mark line in a planar state, and the excessive bleeding edge material is removed, so that the end 211 of the first connecting end 210 is a plane, and the end 211 is arranged perpendicular to the upper surface and the lower surface of the molded plate 20.

In some embodiments, before step S110, step S100 is further included: an adhesive material is provided on the inner surface of the embossing plate 20.

Specifically, referring to fig. 5, the adhesive material 30 is directly attached to the inner surface of the molding plate 20, so that the inner surface of the molding plate 20 has adhesiveness and thus can be attached to an object to be adhered.

Further, the adhesive material 30 is a double-sided tape, and commercially available double-sided adhesive materials can be used as the adhesive material of the present invention.

Further, a release layer 40 is disposed on a side of the adhesive material 30 away from the molding plate 20 for protecting the adhesive material 30, and the optional release layer 40 includes cellophane, silicone oil-coated paper, or wax-coated paper.

Step S140: the second connection end 230 of the molding plate 20 is cut.

Specifically, referring to fig. 6 and 7, the second connecting end 230 is tightened and attached to the first connecting end 210, the position of the cutting line of the second connecting end 230 is determined by directly comparing the first connecting end 211, the cushion layer 50 is disposed under the second connecting end 230 of the molding plate 20, the positioning slot 51 is pre-disposed on the cushion layer 50, and when the cutting line of the second connecting end 230 is parallel to the positioning slot 51, the blade cuts the second connecting end 230 along the positioning slot 51. When the second connecting end 230 is cut, the first connecting end 210 and the main body part 220 of the molded plate 20 are in a bent state, and the outer surface of the molded plate 20 has a certain degree of tensile deformation under the action of material tension, so that when the second connecting end 230 is cut in the bent state, the tensile deformation of the material can be used as length compensation of the outer surface of the molded plate 20, and the size of the plate seam 240 can be reduced.

In some embodiments, referring to fig. 8, after cutting, the end 231 of the second connecting end 230 is a plane, referring to fig. 8, the cushion layer 50 is provided with a vertical positioning groove 511, when cutting, the molded plate 20 is laid on the cushion layer 50, the knife tip moves along the positioning groove 511 to cut the molded plate 20, after cutting is completed, after the second connecting end 230 is fixed on the roller 10, the end 231 is coplanar with the central axis of the roller 10, and after the molded plate roll obtained by the cutting mode is fixed on the roller 10, the end 211 and the end 231 are two approximately parallel planes, thereby being beneficial to reducing the plate seam 240.

In some embodiments, referring to fig. 8, the end 231 of the second connecting end 230 is an inclined surface after cutting, referring to fig. 8, the cushion layer 50 is provided with an inclined positioning groove 512, during cutting, the cushion layer 50 is tangent to the circumferential surface of the roller 10, the molding plate 20 is flatly laid on the cushion layer 50, the tool tip moves along the positioning groove 512 to cut the molding plate 20, after cutting, the length of the outer surface of the molding plate 20 is longer than that of the inner surface thereof in the circumferential direction of the roller 10, and by compensating the length of the outer surface, the reduction of the seam 240 is facilitated.

Further, the end 231 of the second connecting end 230 after cutting is a slant, and the length of the outer surface of the molding plate 20 is 2 π d longer than the length of the inner surface in the circumferential direction of the roller 10 ₁Wherein d is₁As for the thickness of the molding plate 20, the inner and outer surfaces of the molding plate 20 form concentric circles after being attached to the roller 10, and the difference between the circumferences of the two concentric circles is 2 pi d₁Therefore, by setting the above length compensation, the plate gap 240 of the embossing plate can be reduced to within 0.1mm, and the plate gap 240 can be completely eliminated visually.

Step S160 includes: a second attachment end 230 is defined on the roll 10.

Specifically, the adhesive material 30 attached to the inner surface of the embossing plate 20 is firmly attached to the roll 10 by pressing the second connecting end 230, thereby fixing the second connecting end 230.

According to the manufacturing method of the die pressing plate roller, the first connecting end 210 and the main body part 220 of the die pressing plate 20 are fixed on the roller 10, then the second connecting end 230 of the die pressing plate is cut, and in the process of cutting the second connecting end 230 of the die pressing plate 20, the die pressing plate 20 is in a curved surface state, so that the lengths of the upper surface and the lower surface of the die pressing plate 20 can be cut according to actual length requirements, the error of a plate seam 240 is controlled within 0.2mm, and the plate seam 240 is invisible visually because the width of the plate seam 240 is smaller than the minimum width visible to naked eyes of a human body, and further the product quality of a holographic film is improved.

The manufacturing method of the mould pressing plate roller at least has the following advantages:

(1) the process is simple, the existing equipment and materials can be used for completing the manufacture, and the popularization and the application are easy.

(2) The plate seam 240 of the mould pressing plate can be reduced within 0.2mm, so that the plate seam cannot be seen by naked eyes, and the product quality of the holographic film is improved.

Specific examples are as follows.
