Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of die cutting, in particular to a die cutting process and a die cutting system. BACKGROUND

[0002] When a film material is die cut, a die is usually used to punch the film material to cut out the required die cut piece on the film material.

[0003] With the development of technology, the size of the die cut piece is getting smaller and smaller, and the structure of the die cut piece is getting more and more complex. For a die cut piece formed by a plurality of die cut structures, the contour lines of each die cut structure are close to each other, and accordingly, the spacing between each blade on the die corresponding to the die cut piece is small, so that when the die punches the film material, the blade is prone to collapse under the extrusion of the film material.

[0053] The following refers to Figures 1 to 10 The die cutting process of the first aspect of the present application is described in detail.

[0054] Referring to Figure 1 According to the die cutting process of some embodiments of the present application, the following steps are included, but are not limited to:

[0055] Step S100, moving a first processing section 110 on the material belt 10 into the first die cutting area 510, the material belt 10 includes a plurality of first processing sections 110, the plurality of first processing sections 110 are distributed along the length direction of the material belt 10, and each first processing section 110 can be processed to form a die cutting piece 200;

[0056] Step S200, die cutting the part of the material belt 10 located in the first die cutting area 510 to form a first contour 211 in the first processing section 110;

[0057] Step S300, driving the material belt 10 to move so that the first processing section 110 in the first die cutting area 510 moves into the second die cutting area 520;

[0058] At step S400, the part of the material belt 10 located in the second die-cutting area 520 is die-cut to form the second profile 212 and the third profile 221 in the first processing section 110, and to form the first die-cut structure 210 and the second die-cut structure 220, and to form the die-cut piece 200.

[0059] It should be noted that, referring to Figure 6 and Figure 7 , the die-cut piece 200 includes the first die-cut structure 210 and the second die-cut structure 220, the second die-cut structure 220 is completely attached to the first die-cut structure 210, the first die-cut structure 210 has the first profile 211 and the second profile 212, and the second die-cut structure 220 has the third profile 221, and the second profile 212 coincides with the third profile 221 in the horizontal projection plane. Since the second profile 212 of the first die-cut structure 210 and the third profile 221 of the second die-cut structure 220 coincide in the horizontal projection plane, the second profile 212 of the first die-cut structure 210 and the third profile 221 of the second die-cut structure 220 can be die-cut at the same time, and when the material belt 10 is die-cut to form the first die-cut structure 210 and the second die-cut structure 220, the first knife die 300 can be used to die-cut the first profile 211 of the first die-cut structure 210 on the material belt 10, and then the second knife die 400 can be used to die-cut the second profile 212 of the first die-cut structure 210 and the third profile 221 of the second die-cut structure 220 on the material belt 10.

[0060] It should be noted that, referring to Figure 9 and Figure 10 , the first knife die 300 is provided with a first blade group 310 for die-cutting the first profile 211, the first blade group 310 includes a plurality of first blades, and the shape of the first blade group 310 is the same as that of the first profile 211; the second knife die 400 is provided with a second blade group 410 for die-cutting the second profile 212 and the third profile 221, the second blade group 410 includes a plurality of second blades, and the shape of the second blade group 410 is the same as the combined shape of the second profile 212 and the third profile 221.

[0061] In the die-cutting process of the present application, a first processing section 110 on the material tape 10 is first moved into the first die-cutting area 510, the material tape 10 includes a plurality of first processing sections 110, the plurality of first processing sections 110 are spaced apart along the length direction of the material tape 10, and each first processing section 110 can be processed to form a die-cut part 200; then, the part of the material tape 10 located in the first die-cutting area 510 is die-cut to form a first contour 211 in the first processing section 110; then, the material tape 10 is driven to move so that the first processing section 110 in the first die-cutting area 510 moves into the second die-cutting area 520; then, the part of the material tape 10 located in the second die-cutting area 520 is die-cut to form a second contour 212 and a third contour 221 in the first processing section 110, and form a first die-cut structure 210 and a second die-cut structure 220, and form the die-cut part 200.

[0062] It can be understood that the first die-cut structure 210 includes the first contour 211 and the second contour 212, the second die-cut structure 220 includes the third contour 221, and the second contour 212 and the third contour 221 are arranged to coincide in the horizontal projection plane, in the die-cutting process of the present embodiment, the first contour 211 is first die-cut, then the second contour 212 and the third contour 221 are simultaneously die-cut, so that the first contour 211 can be separately die-cut from the second contour 212, and the first contour 211 can be separately die-cut from the third contour 221. Thus, the first blade and the second blade can be arranged on the first die 300 and the second die 400, respectively, to avoid the distance between the first blade and the second blade being too small due to the first blade and the second blade being integrated on the same die, thereby reducing the probability of the first blade or the second blade being broken during die-cutting.

[0063] It should be noted that, in some embodiments of the present application, referring to Figure 6 and Figure 7 , the die-cut part 200 further includes a third die-cut structure 230, the third die-cut structure 230 is completely attached to the first die-cut structure 210, the third die-cut structure 230 has a fourth contour 231, the fourth contour 231 and the second contour 212 partially coincide in the vertical projection plane, and the fourth contour 231 and the first contour 211 are spaced apart by a certain distance.

[0064] In this case, when the material tape 10 is die-cut, the first die-cut structure 210, the second die-cut structure 220 and the third die-cut structure 230 need to be die-cut on the material tape 10, in order to die-cut the first die-cut structure 210, the second die-cut structure 220 and the third die-cut structure 230 on the material tape 10, in some embodiments of the present application, the step S200 further includes but is not limited to the following steps:

[0065] Step S210A, the first profile 211 and the fourth profile 231 are cut to form the third cutting structure 230 in the first processing section 110 located in the first cutting area 510.

[0066] It should be noted that the third cutting structure 230 and the second cutting structure 220 are both attached to the first cutting structure 210, the third cutting structure 230 has the fourth profile 231, and the interval between the fourth profile 231 and the first profile 211 is larger than the interval between the fourth profile 231 and the third profile 221 on the same cutting piece 200. The fourth profile 231 can be cut by the third blade group, and the third blade group includes a plurality of third blades. The shape of the third blade group is the same as the shape of the fourth profile 231. If the third blade group is arranged on the second cutting die 400, the interval between the third blade and the second blade is too small, so that the second blade and the third blade are prone to collapse under the extrusion of the cutting waste when the second cutting die 400 is cutting.

[0067] In the cutting process of the present embodiment, the first profile 211 and the fourth profile 231 of the same cutting piece 200 can be cut on the material belt 10 at the same time, so that the third blade group and the first blade group 310 can be arranged on the first cutting die 300 at the same time. Because the interval between the first profile 211 and the fourth profile 231 is large, the interval between the first blade and the third blade can also be set to be large, so as to reduce the probability of collapse of the first blade and the third blade under the extrusion of the cutting waste.

[0068] It should be noted that in the cutting process, the utilization rate of the material belt 10 needs to be improved as much as possible, that is, the generation of waste needs to be reduced. Therefore, when cutting, the layout of each cutting piece 200 on the material belt 10 needs to be as close as possible.

[0069] Reference Figure 4 and Figure 5In the die-cutting process of the present application, the die-cutting piece 200 is in the shape of a "7", in order to make the layout of the die-cutting piece 200 more compact, the die-cutting piece 200 is in a group of two, and the two die-cutting pieces 200 in the same group are centrally symmetrically distributed, accordingly, the material belt 10 is divided into a plurality of main processing sections 100 along the length thereof, the plurality of main processing sections 100 are spaced apart, each main processing section 100 includes a first processing section 110 and a second processing section 120, the shapes of the first processing section 110 and the second processing section 120 are adapted to the shape of the die-cutting piece 200, one die-cutting piece 200 can be die-cut in each first processing section 110, and one die-cutting piece 200 can be die-cut in each second processing section 120, the first processing section 110 and the second processing section 120 in the same main processing section 100 are centrally symmetrically distributed, and on the material belt 10, the first processing section 110 and the second processing section 120 on the material belt 10 are alternately and spaced apart along the length direction of the material belt 10.

[0070] In some embodiments of the present application, step S100 includes but is not limited to the following steps:

[0071] Step S110, moving a main processing section 100 on the material belt 10 to the first die-cutting station 511 in the first die-cutting area 510.

[0072] Reference Figure 8 , the first die-cutting area 510 includes adjacent first die-cutting station 511 and second die-cutting station 512.

[0073] In further embodiments of the present application, reference Figure 2 , step S200 includes but is not limited to the following steps:

[0074] Step S210B, die-cutting a first processing section 110 located in the first die-cutting station 511 to form a first contour 211;

[0075] Step S220B, moving a main processing section 100 on the material belt 10 located in the first die-cutting station 511 to the second die-cutting station 512;

[0076] Step S230B, die-cutting a second processing section 120 located in the second die-cutting station 512 to form a first contour 211.

[0077] It should be noted that, reference Figure 9 , two groups of first blade groups 310 can be provided on the first cutter 300, the two groups of first blade groups 310 are centrally symmetrically arranged, one group of first blade groups 310 is used for die-cutting a first processing section 110 located in the first die-cutting station 511 to form a first contour 211, and the other group of first blade groups 310 is used for die-cutting a second processing section 120 located in the second die-cutting station 512 to form a first contour 211.

[0078] It can be understood that, due to the two first blade groups 310 provided on the first cutter die 300, when the material belt 10 is in the first die cutting area 510, the first profile 211 can be die cut on the first processing section 110 of one of the two adjacent main processing sections 100, and the first profile 211 can also be die cut on the second processing section 120 of the other main processing section 100, thereby improving the die cutting efficiency of the present die cutting process.

[0079] It can be understood that, due to the die cutting of the two adjacent main processing sections 100 by the first cutter die 300, the two first blade groups 310 on the first cutter die 300 are spaced apart, so as to reduce the probability of the first blades of the two first blade groups 310 being broken.

[0080] In some embodiments of the present application, referring to Figure 8 , the second die cutting area 520 comprises adjacent third and fourth die cutting stations 521 and 522, and the second die cutting station 512 and the third die cutting station 521 are adjacent.

[0082] Step S310, moving the main processing section 100 on the material belt 10 to the first die cutting station 511 in the first die cutting area 510.

[0083] It can be understood that, after the first processing section 110 is die cut to form the first profile 211 in the first die cutting area 510, it needs to be moved to the second die cutting area 520 to be die cut to form the second and third profiles 212 and 221.

[0084] In further embodiments of the present application, referring to Figure 3 , in step S400, the following steps are included but not limited to:

[0085] Step S410, die cutting the first processing section 110 at the third die cutting station 521 to form the second and third profiles 212 and 221;

[0086] Step S420, moving the main processing section 100 at the third die cutting station 521 on the material belt 10 to the fourth die cutting station 522;

[0087] Step S430, die cutting the second processing section 120 at the fourth die cutting station 522 to form the second and third profiles 212 and 221.

[0088] It should be noted that, referring to Figure 10The second die 400 can be provided with two groups of second blade groups 410, and the two groups of second blade groups 410 are symmetrically arranged at the center, one group of second blade groups 410 is used for forming the second profile 212 and the third profile 221 on the first processing section 110 at the third die cutting station 521, and the other group of second blade groups 410 is used for forming the second profile 212 and the third profile 221 on the second processing section 120 at the fourth die cutting station 522.

[0089] It can be understood that, due to the fact that the second die 400 is provided with two groups of second blade groups 410, when the material belt 10 is in the second die cutting area 520, the first processing section 110 of one of the adjacent two main processing sections 100 can form the second profile 212 and the third profile 221, and the second processing section 120 of the other main processing section 100 can also form the second profile 212 and the third profile 221, thereby improving the die cutting efficiency of the die cutting process.

[0090] It can be understood that, due to the fact that the second die 400 simultaneously cuts the adjacent two main processing sections 100, the two second blade groups 410 on the second die 400 have a large interval, so as to reduce the probability of blade collapse of the second blades of the two second blade groups 410.

[0091] In some embodiments of the present application, along the moving direction of the material belt 10, in the same main processing section 100, the first processing section 110 is located at the front side of the second processing section 120.

[0092] It can be understood that, along the moving direction of the material belt 10, in the same main processing section 100, by arranging the first processing section 110 at the front side of the second processing section 120, the interval between the two first blade groups 310 in the first die 300 can be larger, and the interval between the two second blade groups 410 in the second die 400 can be larger.
