Description

Technical Field

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

[0002] When the die-cutting equipment is working, the material strip needs to be continuously fed into the die-cutting area of ​​the die-cutting mechanism so that the die-cutting mechanism can die-cut the required finished workpieces in various areas of the material strip. However, some areas of the material strip may have defects such as material joints and scratches. After the die-cutting mechanism processes the areas with defects on the material strip, the finished workpieces produced are also defective. These defective workpieces will be mixed with the good workpieces, and an additional inspection and classification process needs to be set up in the later stage to remove these defective workpieces, which is time-consuming and labor-intensive. Utility Model Content

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, a first aspect of this invention provides a die-cutting device that, in this embodiment, avoids areas with defects on the material strip during die-cutting. A second aspect of this invention also provides a die-cutting system.

[0004] A die-cutting apparatus according to a first aspect of the present invention includes a die-cutting mechanism, a detection mechanism, and a cutting barrier mechanism. The die-cutting mechanism includes an upper die, a lower die, and a first driving structure. A die-cutting area is formed between the upper die and the lower die. The first driving structure is connected to at least one of the upper die and the lower die and is used to drive the upper die and the lower die to move closer or further apart to die-cut the strip in the die-cutting area. The detection mechanism is used to detect whether there is a defect in the strip entering the die-cutting area. The cutting barrier mechanism is disposed on one side of the die-cutting area and includes a second driving structure and a cutting barrier. The second driving structure is connected to the cutting barrier and electrically connected to the detection mechanism. When the detection mechanism detects that there is a defect in the strip entering the die-cutting area, the second driving structure drives the cutting barrier to extend into the die-cutting area so that the cutting barrier prevents the upper die and the lower die from closing.

[0005] A die-cutting apparatus according to a first aspect of the present invention has at least the following technical effects:

[0006] In the operation of the die-cutting equipment of this application, the material strip is conveyed to the die-cutting area of ​​the die-cutting mechanism. The upper and lower dies approach each other under the drive of the first drive structure. When the detection mechanism detects a defect on the material strip, the second drive structure in the blocking mechanism drives the blocking element to extend into the die-cutting area to prevent the upper and lower dies from closing. This prevents the upper and lower dies from die-cutting the defective area of ​​the material strip. When the detection mechanism does not detect a defect on the material strip, the upper and lower dies close normally under the drive of the second drive structure, and the good area of ​​the material strip is die-cut normally. From the above operation process, it can be seen that this application can enable the die-cutting mechanism to avoid the defective area on the material strip through the blocking mechanism, so that defective products will not be completely formed on the material strip, thus eliminating the need to remove defective products and improving the production efficiency of the die-cutting equipment.

[0010] According to a first aspect of the present invention, a die-cutting device includes a cutting barrier and a connecting part. The cutting barrier extends horizontally and is used to prevent the upper and lower dies from closing. The connecting part extends vertically. One end of the cutting barrier away from the die-cutting area is connected to the lower end of the connecting part, and the upper end of the connecting part is connected to the output end of the second driving structure.

[0011] According to a first aspect of the present invention, a die-cutting device includes a cutting mechanism comprising a plurality of cutting members with different cutting thicknesses; a second driving structure is detachably connected to a connecting portion of one of the cutting members.

[0027] The following is for reference. Figure 1 A die-cutting device according to the first aspect of this utility model will be described in detail.

[0028] refer to Figure 1 According to a first aspect embodiment of the present invention, a die-cutting device includes a die-cutting mechanism 100, a detection mechanism 200, and a cutting blocking mechanism 300. The die-cutting mechanism 100 includes an upper die 110, a lower die 120, and a first driving structure (not shown in the figure). A die-cutting area 100a is formed between the upper die 110 and the lower die 120. The first driving structure is connected to at least one of the upper die 110 and the lower die 120 and is used to drive the upper die 110 and the lower die 120 to move closer or further apart to die-cut the strip material in the die-cutting area 100a. The detection mechanism 200 is used to... The detection mechanism 200 is used to detect whether there are defects in the strip entering the die-cutting area 100a. The blocking mechanism 300 is located on one side of the die-cutting area 100a. The blocking mechanism 300 includes a second drive structure 310 and a blocking member 320. The second drive structure 310 is connected to the blocking member 320 and is electrically connected to the detection mechanism 200. When the detection mechanism 200 detects that there are defects in the strip entering the die-cutting area 100a, the second drive structure 310 drives the blocking member 320 to extend into the die-cutting area 100a so that the blocking member 320 prevents the upper mold 110 and the lower mold 120 from closing.

[0029] In the operation of the die-cutting equipment of this application, the material strip is conveyed to the die-cutting area 100a of the die-cutting mechanism 100. The upper die 110 and the lower die 120 approach each other under the drive of the first drive structure. When the detection mechanism 200 detects a defect on the material strip, the second drive structure 310 in the blocking mechanism 300 drives the blocking member 320 to extend into the die-cutting area 100a to prevent the upper die 110 and the lower die 120 from closing. This prevents the upper die 110 and the lower die 120 from die-cutting the defective area of ​​the material strip. When the detection mechanism 200 does not detect a defect on the material strip, the upper die 110 and the lower die 120 close normally under the drive of the second drive structure 310, and die-cut the good area of ​​the material strip normally. From the above operation process, it can be seen that this application can enable the die-cutting mechanism 100 to avoid the defective area on the material strip through the blocking mechanism 300, so that defective products will not be completely formed on the material strip, thus eliminating the need to remove defective products and improving the production efficiency of the die-cutting equipment.

[0030] Understandably, by setting the blocking mechanism 300 to prevent the upper mold 110 and the lower mold 120 from closing, no changes are needed during operation, thereby reducing the possibility of cumulative errors in the material strip due to the conveying speed of the material strip and the closing speed of the die-cutting mechanism 100.

[0031] refer to Figure 1 In some embodiments of this utility model, multiple cutting-blocking mechanisms 300 are provided, and the multiple cutting-blocking mechanisms 300 are distributed circumferentially around the die-cutting area 100a. It can be understood that by providing multiple cutting-blocking mechanisms 300 circumferentially around the die-cutting area 100a of the die-cutting mechanism 100, the cutting-blocking mechanisms 300 can prevent the upper mold 110 and the lower mold 120 from closing in the circumferential direction.

[0032] refer to Figure 1 In some embodiments of this utility model, the second drive structure 310 is fixedly installed on the upper mold 110 or the lower mold 120. It is understood that by installing the second drive structure 310 on the upper mold 110 or the lower mold 120, the installation of the cutting mechanism 300 becomes simpler and more convenient.

[0033] like Figure 1 As shown, in some embodiments, the first drive structure is connected to the upper mold 110 and is used to drive the upper mold 110 to perform lifting and lowering movements; the second drive structure 310 is fixedly installed on the upper mold 110 and is used to drive the cutting barrier 320 to extend into or out of the die-cutting area 100a in the horizontal direction. It can be understood that when the strip is conveyed to the die-cutting area 100a of the die-cutting mechanism 100, the upper mold 110 approaches the lower mold 120 under the drive of the first drive structure. When the detection mechanism 200 detects a defect on the strip, the second drive structure 310 drives the cutting barrier 320 to extend into the die-cutting area 100a in the horizontal direction to prevent the upper mold 110 and the lower mold 120 from closing, thus preventing the upper mold 110 and the lower mold 120 from die-cutting the defective area of ​​the strip. When the detection mechanism 200 does not detect a defect on the strip, the upper mold 110 closes normally with the lower mold 120 under the drive of the second drive structure 310, and the good area of ​​the strip is die-cut normally.

[0034] It is understandable that by placing the second drive structure 310 on the upper die 110 and driving the cutting member 320 to move in the horizontal direction, it is possible to prevent the upper die 110 from affecting the cutting member 320 extending into the die-cutting area 100a during the movement.

[0035] like Figure 1As shown, in one embodiment, the cutting member 320 includes a cutting portion 321 and a connecting portion 322. The cutting portion 321 extends horizontally and is used to prevent the upper mold 110 and the lower mold 120 from closing. The connecting portion 322 extends vertically. The end of the cutting portion 321 away from the die-cutting area 100a is connected to the lower end of the connecting portion 322, and the upper end of the connecting portion 322 is connected to the output end of the second drive structure 310. It can be understood that since the connecting portion 322 extends vertically and the cutting portion 321 extends horizontally, and the lower end of the connecting portion 322 is connected to the cutting portion 321, and the upper end of the connecting portion 322 is connected to the second drive structure 310, by setting the connecting portion 322, the installation space of the second drive structure 310 is larger, and the possibility of interference between the second drive structure 310 and the material strip is reduced.

[0036] like Figure 1 As shown, in some embodiments, the cutting mechanism 300 includes multiple cutting elements 320 with different thicknesses of the cutting portion 321; the second drive structure 310 is detachably connected to the connecting portion 322 of one of the cutting elements 320. It is understood that operators can adaptably replace different cutting elements 320 according to needs; for example, for materials with greater thickness, a thinner cutting element 320 can be used, while for materials with less thickness, a thicker cutting element 320 can be selected.

[0037] like Figure 1 As shown, in some embodiments, the second drive structure 310 includes a mounting plate 311, a cylinder 312, and a solenoid valve 313. The mounting plate 311 is connected to the upper mold 110, the cylinder 312 is mounted on the end of the mounting plate 311 away from the upper mold 110, the solenoid valve 313 is ventilated to the cylinder 312, the solenoid valve 313 is electrically connected to the detection mechanism 200, and the output end of the cylinder 312 is connected to the cutting element 320. Understandably, when the detection mechanism 200 detects a defect on the strip, it transmits a signal to the solenoid valve 313, which then switches to the open state. This allows the cylinder 312 to drive the cutting element 320 to extend into the die-cutting area 100a. The cutting element 320 prevents the die-cutting mechanism 100 from die-cutting the strip. When the detection mechanism 200 detects no defect on the strip, it transmits a signal to the solenoid valve 313, which closes. The cylinder 312 then drives the cutting element 320 away from the die-cutting area 100a. At this point, the die-cutting mechanism 100 can die-cut the strip normally.

[0038] refer to Figure 1 In some embodiments of this utility model, the detection mechanism 200 is a color mark sensor or a CCD camera. It is understood that using a color mark sensor or a CCD camera for the detection mechanism 200 is relatively simple and has a lower cost.

[0039] The following is a detailed description of a die-cutting system according to a second aspect of the present invention.

[0040] A die-cutting system according to a second aspect embodiment of the present invention includes the die-cutting equipment as described in the first aspect embodiment. It is understood that by incorporating the die-cutting system of the first aspect embodiment into the die-cutting system, the die-cutting mechanism 100 can avoid defective areas on the material strip through the blocking mechanism 300, preventing the complete formation of defective products on the material strip, thereby eliminating the need to remove defective products and improving the overall production efficiency of the die-cutting system.

[0041] In some embodiments of this utility model, the die-cutting system further includes a conveying mechanism for continuously conveying the material strip through the die-cutting area 100a. It is understood that the conveying mechanism transports the material strip to the die-cutting area 100a of the die-cutting mechanism 100. The upper die 110 and the lower die 120 approach each other under the drive of the first driving structure. When the detection mechanism 200 detects a defect on the material strip, the blocking mechanism 300 prevents the die-cutting mechanism 100 from die-cutting the defective area of ​​the material strip. When the detection mechanism 200 does not detect a defect on the material strip, the die-cutting mechanism 100 performs normal die-cutting on the good area of ​​the material strip.

[0042] Understandably, by setting the blocking mechanism 300 to prevent the upper mold 110 and the lower mold 120 from closing, no changes are needed during operation, thereby reducing the possibility of cumulative errors in the material belt caused by intermittent changes in the conveying speed of the conveying mechanism.

[0043] 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.
