Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, and in particular to a die-cutting system. Background Technology

[0002] Some die-cut parts include sheet material and adhesive material. The sheet material includes a main body and a handle, and the adhesive material is attached to the main body.

[0003] In related technologies, when die-cutting such parts, it is necessary to first combine the film material and the tape, and then die-cut the film material and the tape to form a sheet material and the tape material to form a glue material. After that, the glue waste on the handle is removed.

[0004] However, due to the small area of ​​the handle, when the waste removal membrane is used to remove the adhesive waste from the handle, the adhesive material tends to stick together with the membrane. As a result, when the waste removal membrane removes the adhesive waste from the handle, it also tends to remove the adhesive material from the main body. Utility Model Content

[0034] The following is for reference. Figures 1 to 4 The die-cutting system of this application is described in detail.

[0035] refer to Figure 3 The die-cutting device of this utility model is used to die-cut to form a die-cut part 600. The die-cut part 600 includes a second sheet 630, an adhesive material 620 and a first sheet 610 that are sequentially laminated. The second sheet 630 includes a supporting part 631 and two bending parts 632. The two opposite sides of the adhesive material 620 are respectively attached to the supporting part 631 and the main body part 612 of the first sheet 610.

[0036] refer to Figure 1 and Figure 2 The die-cutting system according to an embodiment of the present invention includes a first die-cutting device 100 and a waste discharge device 200.

[0037] The first die-cutting device 100 is used to die-cut the first film material and the adhesive tape to form a first sheet 610 and an adhesive material 620, respectively. The first sheet 610 includes a main body portion 612 and a handle portion 611 connected to each other. The first die-cutting device 100 can attach the first sheet 610 to the first support film and attach the adhesive material 620 to the main body portion 612. The first sheet 610, the adhesive material 620, and the first support film together form a first composite. The waste discharge device 200 includes a waste discharge film output roller. 210, waste discharge roller group 220 and first take-up roller 230, waste discharge film output roller 210 is used to output waste discharge film, waste discharge roller group 220 is arranged on the moving path of waste discharge film and first composite component, waste discharge roller group 220 includes pressure roller 221 and bottom roller 222, the roller surface of pressure roller 221 is provided with protrusion 221a, the protrusion 221a is used to cooperate with bottom roller 222 to stick the glue waste on handle part 611 to waste discharge film, and the first take-up roller 230 is used to take up the waste discharge film with glue waste attached.

[0038] It should be noted that when the die-cutting system of this application is working, the first die-cutting device 100 will die-cut the first film material and the adhesive tape to form a first sheet 610 and an adhesive material 620 respectively. The first sheet 610 includes a handle portion 611 and a main body portion 612. The adhesive material 620 is attached to the main body portion 612, and there is still adhesive waste left from the die-cutting of the adhesive tape on the handle portion 611. The first sheet 610 is attached to the first support film. The first sheet 610, the adhesive material 620, and the first support film together constitute the first composite part. The waste removal device 200 includes a waste film output roller 210, a waste roller group 220, and a first take-up roller 210. 30. The waste discharge roller group 220 includes a pressure roller 221 and a bottom roller 222. The pressure roller 221 is provided with a protrusion 221a. The waste discharge film output roller 210 is used to output the waste discharge film. The waste discharge roller group 220 is located on the common moving path of the waste discharge film and the first composite. After the waste discharge film and the first composite enter between the pressure roller 221 and the bottom roller 222, under the push of the protrusion 221a on the pressure roller 221, the waste discharge film part deforms downward and approaches the handle part 611 of the first sheet 610 so that the waste discharge film can adhere to the glue waste on the handle part 611. After the waste discharge film adheres to the glue waste on the handle part 611, it is wound up by the first take-up roller 230.

[0039] Understandably, due to the protrusion 221a on the pressure roller 221, the waste discharge membrane can partially approach and adhere to the adhesive waste on the handle portion 611 under the pressure of the protrusion 221a, while other areas of the waste discharge membrane can maintain a certain distance from the first composite, thereby reducing the probability of the waste discharge membrane adhering to the adhesive material 620 on the main body portion 612 of the first sheet 610.

[0040] In some embodiments of this utility model, reference is made to Figure 1The first die-cutting device 100 includes a composite film material conveying roller 110, a first backing film conveying roller 120, and a first die-cutting roller group 130. The composite film material conveying roller 110 is used to convey a composite film material containing a first film material and an adhesive tape to the first die-cutting roller group 130. The first backing film conveying roller 120 is used to convey a first backing film to the first die-cutting roller group 130. The first die-cutting roller group 130 is used to die-cut the composite film material and the first backing film to form a first composite part.

[0041] Understandably, when the first die-cutting device 100 is working, the composite film material conveying roller 110 conveys the composite film material to the first die-cutting roller group 130, and the first backing film conveys the first backing film to the first die-cutting roller group 130. The composite film material and the first backing film are combined together at the first die-cutting roller group 130. The first die-cutting roller group 130 performs die-cutting on the first film material and the tape according to the contour of the first sheet 610, and performs die-cutting on the tape according to the contour of the adhesive material 620. Thus, the first die-cutting roller group 130 die-cuts the first sheet 610 on the first film material and forms the adhesive material 620 on the tape. The adhesive material 620 is attached to the handle portion 611 of the first sheet 610.

[0042] In some embodiments of this utility model, reference is made to Figure 1 The die-cutting system also includes a second die-cutting device 300 and a composite roller group 400. The second die-cutting device 300 is used to die-cut the second film material to form a second sheet 630 and can attach the second sheet 630 to the second backing film. The composite roller group 400 is disposed on the moving path of the first composite and the second backing film and is used to attach the first composite to the second sheet 630 to form the second composite. In the second composite, the second sheet 630 is attached to the adhesive material 620.

[0043] It is understood that when the die-cutting system of this application is working, the second die-cutting device 300 can die-cut the second film material to form a second sheet 630, and the second sheet 630 is attached to the second backing film. The composite roller group 400 is disposed on the moving path of the first composite and the second backing film. After the first composite and the second backing film have both moved to the composite roller group 400, under the action of the composite roller group 400, the first composite is transferred to the second sheet 630 of the second backing film to form the second composite. At this time, the second sheet 630 is supported on the second backing film, and the second sheet 630 and the first sheet 610 are bonded together by the adhesive 620. The first backing film is attached to the upper surface of the first sheet 610.

[0044] In a further embodiment of this utility model, reference is made to... Figure 1The second die-cutting device 300 includes a second film material conveying roller 310, a second base film conveying roller 320, and a second die-cutting roller group 330. The second film material conveying roller 310 and the second base film conveying roller 320 are respectively used to convey the second film material and the second base film to the second die-cutting roller group 330. The second die-cutting roller group 330 is used to die-cut the second film material into a second sheet 630.

[0045] It is understood that the second die-cutting device 300 includes a second film material conveying roller 310, a second backing film conveying roller 320, and a second die-cutting roller group 330. The second film material conveying roller 310 conveys the second film material to the second die-cutting roller group 330, and the second backing film conveying roller 320 conveys the second backing film to the second die-cutting roller group 330. The second film material and the second backing film are combined at the second die-cutting roller group 330 so that the second film material is supported on the second backing film. In the second die-cutting roller group 330, the second die-cutting roller group 330 performs die-cutting on the second film material on the second backing film to form a second sheet 630. At this time, the second sheet 630 is supported on the second backing film.

[0046] In a further embodiment of this utility model, reference is made to... Figure 1 The second die-cutting device 300 also includes a fourth take-up roller 340, which is used to take up the waste film generated after the second die-cutting roller group 330 has die-cut the second film material.

[0047] In some embodiments of this utility model, reference is made to Figure 1 The die-cutting system also includes a bending device 500, which is located on the moving path of the second composite and is used to bend the second sheet 630 of the second composite.

[0048] It is understandable that when the second composite part moves to the bending device 500, the bending device 500 can bend the second sheet 630 so that the two ends of the second sheet 630 are bent towards the middle in the width direction of the second backing film.

[0049] In some embodiments of this utility model, reference is made to Figure 1 The bending device 500 includes a third die-cutting roller group 510 and a bending fixture 520. The third die-cutting roller group 510 and the bending fixture 520 are both located on the common moving path of the second composite and the second support film. The bending fixture 520 is located behind the third die-cutting roller group 510. The third die-cutting roller group 510 is used to die-cut creases on the second sheet 630 of the second composite to divide the second sheet 630 into a connected support portion 631 and a bending portion 632. The first composite is attached to the support portion 631. The bending fixture 520 is used to guide the bending portion 632 to bend relative to the support portion 631 along the crease.

[0050] Understandably, by setting up the third die-cutting roller group 510, before the second composite part enters the bending fixture 520 to bend the second sheet 630, the third die-cutting roller group 510 can die-cut the second sheet 630 to create creases on the second sheet 630, thereby enabling the subsequent bending fixture 520 to complete the bending of the second sheet 630 more smoothly. At the same time, the setting of these creases can reduce the probability of the bent part 632 automatically resetting.

[0051] In some embodiments of this utility model, reference is made to Figure 1 The bending device 500 also includes a fifth take-up roller 570, which is used to take up the first backing film on the second composite before the second composite enters the third die-cutting roller group 510.

[0052] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 The second sheet 630 includes a supporting portion 631 and two bending portions 632. The two bending portions 632 are respectively connected to the two opposite ends of the supporting portion 631. The bending fixture 520 is provided with a guide channel 521 that allows the second composite to pass through. The guide channel 521 has a first side wall 521a, a bottom wall 521b and a second side wall 521c connected in sequence. There is a first angle between the first side wall 521a and the bottom wall 521b, and there is a second angle between the second side wall 521c and the bottom wall 521b. After the second composite enters the guide channel 521, under the limitation of the first side wall 521a and the second side wall 521c, the two bending portions 632 bend towards the middle of the supporting portion 631, so that one of the bending portions 632 forms a first angle with the supporting portion 631, and the other bending portion 632 forms a second angle with the supporting portion 631.

[0053] When the second sheet 630 includes two bending portions 632, in some embodiments of the present invention, referring to the figures, two third die-cutting roller groups 510 are provided, and the two third die-cutting roller groups 510 are respectively used to die-cut two creases on the second sheet 630.

[0054] In some embodiments of this utility model, reference is made to Figure 1 The second die-cutting device 300 also includes a release film conveying roller 350, which is used to convey the release film to the second die-cutting roller group 330 so that the release film is located between the bending portion 632 and the second support film.

[0055] It should be noted that the bending portion 632 of the second sheet 630 needs to be bent relative to the supporting portion 631. When the bending portion 632 is bent, it needs to be separated from the second backing film. Since the second sheet 630 has a certain degree of adhesion, if the bending portion 632 is in direct contact with the second backing film, the bending portion 632 may stick too tightly to the second backing film during subsequent bending, resulting in the bending portion 632 failing to bend.

[0056] In some embodiments of this utility model, reference is made to Figure 1 The second die-cutting device 300 also includes a release film conveying roller 350, which can output a release film and can be laminated between the bending portion 632 and the second support film, so that the bearing portion 631 of the second sheet 630 in the second composite is attached to the second support film. The bending portion 632 of the second sheet 630 in the second composite is separated from the second support film by a release film. The release film can reduce the probability that the bending portion 632 will fail to bend due to excessive adhesion between the bending portion 632 and the second support film.

[0057] In some embodiments of this utility model, reference is made to Figure 1 The bending device 500 also includes a fourth die-cutting roller group 530 and a second take-up roller 540. The fourth die-cutting roller group 530 is located on the common moving path of the second composite and the second base film, and is located in front of the third die-cutting roller group 510. The fourth die-cutting roller group 530 is used to slit the second base film to form a first sub-base film and a second sub-base film. The second composite is carried on the first sub-base film. The second take-up roller 540 is used to take up the second sub-base film.

[0058] Understandably, by setting up the fourth die-cutting roller group 530, the fourth die-cutting roller group 530 can slit the second base film to form the first sub-base film and the second sub-base film, while the second composite is carried on the first sub-base film, and the second take-up roller 540 is used to take up the second sub-base film, thereby reducing the width of the second base film to match the width of the second composite.

[0059] In some embodiments of this utility model, reference is made to Figure 1 The bending device 500 also includes a third bottom film conveying roller 550 and a third take-up roller 560. The third bottom film conveying roller 550 is used to convey the third bottom film to the fourth die-cutting roller group 530. The third bottom film is used to carry the second bottom film. The third take-up roller 560 is used to take up the third bottom film.

[0060] Understandably, since the fourth die-cutting roller group 530 needs to slit the second backing film, the third backing film conveying roller 550 is set up so that it can output the third backing film to the fourth die-cutting roller group 530, so that the third backing film can support the second backing film, and thus the fourth die-cutting roller group 530 can successfully complete the slitting of the second backing film.

[0061] In some embodiments of this utility model, reference is made to Figure 1 The waste discharge device 200 also includes a pressure film conveying roller 240, a pressure film take-up roller 250, and a pressure roller group 260. The pressure roller group 260 is located on the moving path of the first composite component and is located behind the waste discharge roller group 220. The pressure film conveying roller 240 is used to convey the pressure film to the pressure roller group 260, and the pressure film take-up roller 250 is used to receive the pressure film output by the pressure roller group 260. The pressure roller group 260 can squeeze the handle part 611 tightly against the first bottom support film through the pressure film.

[0062] It should be noted that the first sheet 610 includes a handle portion 611 and a main body portion 612, while the adhesive material 620 is only attached to the main body portion 612. After the waste removal membrane removes the adhesive waste on the handle portion 611, the waste removal membrane will cause the handle portion 611 to lift upward, thereby affecting the subsequent bonding of the first composite part and the second sheet 630.

[0063] In the die-cutting system of this embodiment, the pressure film conveying roller 240 can convey the pressure film to the pressure roller group 260. Under the action of the pressure roller group 260, the pressure film can squeeze the handle so that the handle can stick tightly to the first support film, thereby allowing the raised handle part 611 to return to its original state.

[0064] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
