Fig. 1 shows a schematic structural view of a die-cutting device for flexible adhesive members according to the present embodiment. As shown in fig. 1, the die cutting device of the flexible adhesive member includes a laminating roller 1 and an auxiliary roller 2 which is matched with the laminating roller 1.

The flexible adhesive member in this embodiment refers to a sheet-like member comprising a face material and a substrate with a degree of adhesion (pressure sensitive adhesive or electrostatic adhesion) between the face material and the substrate. However, it should be understood by those skilled in the art that the die-cutting device in this embodiment may be applied to cutting other non-adhesive sheet members, and the multi-mode functional effect of the die-cutting device in this embodiment cannot be fully reflected, which does not belong to the main application scenario of the die-cutting device in this embodiment.

In this embodiment, the outer periphery of the auxiliary roller 2 may be provided with a rubber pressing layer, so that in the process of matching the grinding roller 1 and the auxiliary roller 2 with die cutting, the cutter body on the grinding roller 1 can implement pressing cutting with a certain depth on the material belt where the flexible adhesive piece is located.

Referring to fig. 2-4, the grinding roller 1 in the present embodiment includes a roller core 11, a plurality of die cutting plates 12 and a plurality of die cutting tools 15, wherein the plurality of die cutting plates 12 are disposed along an outer periphery of the roller core 11, and each of the die cutting plates 12 extends along an axial direction of the roller core 11; the die cutting plate 12 is provided with a first end 12a and a second end 12b at two ends along the circumferential direction of the roller core 11, the first end 12a and the second end 12b are connected with the roller core 11 through a first screw 13 and a second screw 14 respectively, the distance between the first end 12a and the roller core 11 can be adjusted through the first screw 13, and the distance between the second end 12b and the roller core 11 can be adjusted through the second screw 14; the die plate 12 has a first state in which the distance between the first end 12a and the roll core 11 is equal to the distance between the second end 12b and the roll core 11, a second state in which the distance between the first end 12a and the roll core 11 is smaller than the distance between the second end 12b and the roll core 11, and a third state in which the distance between the first end 12a and the roll core 11 is greater than the distance between the second end 12b and the roll core 11; a plurality of die cutters 15 are provided on the plurality of die cutter plates 12 in one-to-one correspondence.

In this embodiment, the die cutting device is in a uniform cut mode (the same degree of cutting about one flexible applicator) when the die cutting rule plate 12 is in the first state. At this time, the distance between the die cutting blade 12 and the roller core 11 can be adjusted to cut flexible stickers of different thicknesses, or the cutting depth of a certain flexible stickers can be adjusted: when the cutting of the flexible adhesive piece with the thinner thickness is changed into the cutting of the flexible adhesive piece with the thicker thickness, the first screw joint piece 13 and the second screw joint piece 14 are adjusted to increase the distance between the die-cutting knife plate 12 and the roller core 11, and conversely, the distance between the die-cutting knife plate 12 and the roller core 11 is reduced; when the cutting of only the face material is changed from the cutting of a certain flexible adhesive member to the cutting of both the face material and the base material, the first screw 13 and the second screw 14 are adjusted to increase the distance between the die-cutting blade 12 and the roll core 11, and conversely, the distance between the die-cutting blade 12 and the roll core 11 is decreased.

In this embodiment, when the die cutting rule plate 12 is in the second state or the third state, the die cutting device is in the non-uniform cutting mode (the cutting degree is different for the periphery of one flexible adhesive member, only the face material is cut at the end with the smaller median of the first distance and the second distance, and both the face material and the substrate are cut at the other end). At this time, the flexible stickers of different thicknesses may be cut by adjusting the size of the first distance (the distance between the first end 12a of the die cutter plate 12 and the roller core 11) and the second distance (the distance between the second end 12b of the die cutter plate 12 and the roller core 11): when cutting a thicker flexible adhesive of the facestock, the first screw 13 is adjusted to increase the first distance (assuming the first distance is less than the second distance) while the second distance is adjusted according to the overall thickness of the flexible adhesive. At this time, the width of only the cut facestock portion may also be adjusted by adjusting the size of the second distance (assuming the first distance is smaller than the second distance, otherwise, the first distance is adjusted here): when it is desired to increase the width of only the portion of the flexible adhesive element where the substrate is not cut, the second threaded member 14 is adjusted to decrease the second distance, and conversely, the second threaded member 14 is adjusted to increase the second distance.

In the present embodiment, when the plurality of die cutting plates 12 are in two or more of the first state, the second state, and the third state, or when the plurality of die cutting plates 12 are in the same state but are different in distance from the roll core 11, the die cutting device is in the hybrid cutting mode. The die cutting device in this mode can die cut two flexible stickers on one roll: one of the die cutter plates 12 corresponding to one of the flexible stickers may be set in a first state in which the flexible stickers are cut uniformly and can be separated from the material tape (both the surface material and the substrate are cut off), while the die cutter plate 12 corresponding to the other flexible stickers is set in a first state in which the flexible stickers are cut uniformly and only the surface material of the flexible stickers is cut off; it is also possible to provide a first state in which the die cutter plate 12 corresponding to one of the flexible stickers is uniformly cut and the flexible stickers can be cut off from the web (both the facestock and the substrate are cut off), and a second state or a third state in which the die cutter plate 12 corresponding to the other flexible stickers is in the second state. At this time, the specific adjustment of each of the die cutting plates 12 may be performed with reference to the descriptions of the uniform cutting mode and the non-uniform cutting mode, and will not be described herein.

In addition, in order to improve the adjustment accuracy when the die cutting device in the present embodiment performs the above adjustment, as shown in fig. 4, the grinding roller 1 may be provided with a plurality of distance sensor groups, wherein the plurality of distance sensor groups are disposed on the roller core 11, and each distance sensor group is disposed corresponding to one die cutter plate 12; one distance sensor group includes at least two distance sensors 16 respectively disposed at the first end 12a and the second end 12b of the stencil 12 to detect a first distance and a second distance; in order to further improve the detection accuracy of the first distance and the second distance, two or more distance sensors 16 corresponding to the first end 12a and the second end 12b of the die plate 12 may be provided.

It should be understood by those skilled in the art that the purpose of adjusting the first distance and the second distance in this embodiment is basically to adjust the distance between the blade edge of the blade body and the roll core in the die-cutting tool 15, that is, to adjust the pressing depth when the blade body in the die-cutting tool 15 presses and cuts the flexible adhesive member; in order to reduce unnecessary conversion, the default die cutting plate 12 in this embodiment has uniform thickness throughout, the die cutting tool 15 has uniform thickness throughout, and the die cutting tool 15 has uniform height of the tool body; however, for the case that the thicknesses of the first end 12a and the second end 12b of the die cutting plate 12 are different, or the thicknesses of the corresponding ends of the die cutting tool 15 are different, or the heights of the tool bodies on the corresponding ends of the die cutting tool 15 are different, only a simple addition and subtraction calculation is performed by considering the thickness difference and/or the height difference when the first distance and the second distance are adjusted, and the corresponding embodiments still fall within the protection scope of the present invention.

In summary, the die cutting device for the flexible adhesive part in this embodiment has a plurality of die cutter plates 12 through setting up the roller core 11 periphery of the roller 1 therein, and set up the distance between each die cutter plate 12 and the roller core 11 in both ends (first end 12a and second end 12 b) on circumference can be adjusted through the spiro union piece (the distance between first end 12a and second end 12b can be adjusted through first spiro union piece 13 and second spiro union piece 14 respectively), so that the die cutting device for the flexible adhesive part both can be in the condition that the distance between first end 12a and second end 12b and roller core 11 is equal, through the size of adjusting this distance (actually, the degree of pressing between adjusting cutter and auxiliary roller 2) implementation uniform division (for example cut down the flexible adhesive part from the material area completely, or just cut the plane materiel and the substrate still keeps the integrality so as to be convenient for the rolling), also can be through the difference in the distance between first end 12a and second end 12b and roller core 11, can be in the condition that the same as the cut down of the flexible adhesive part is cut down, the flexible adhesive part can be cut down, the adhesive part can be cut down by the degree of the same as the distance between the flexible adhesive part and the material, the corresponding to the flexible adhesive part is not cut down, the condition can be realized, the adhesive part can be cut down, and the adhesive part is cut down well, and the adhesive part is cut down by the different in the degree can be cut down, and the surface material can be cut down and the surface material is cut down and the surface evenly.

It will be appreciated by those skilled in the art that the first countersunk screw 131 in this embodiment does not have a threaded relationship with the die cutting plate 12, and the first countersunk screw 131 passes through the die cutting plate 12 only via a through hole.

In order to prevent the die cutting roller 1 from changing due to the pressing and pressing during the material cutting process of the auxiliary roller 2, the spring 132 in the embodiment needs to have a higher stiffness coefficient, and the elastic force of the spring when the spring is abutted between the die cutting roller 12 and the roller core 11 is set to be larger than the pressing force of the roller 1 when the spring is pressed and cut.
