[0030] Embodiment
[0031] In order to solve the problem that in the existing die-cutting equipment, it is not easy for operators to find the joints after multiple materials are stacked, which is likely to cause poor product functionality and poor use. Referring to Figures 1-4 as shown, the present application discloses a die-cutting device with material joint detection and marking, including a plurality of die-cutting machines and a plurality of detection and marking mechanisms 20. A plurality of detection and marking mechanisms 20 are arranged outside some of the die-cutting machines. The detection and marking mechanism 20 includes a detection component and a marking component;
[0032] The detection component includes a Z-shaped bracket 21 rotatably arranged on the base of the die-cutting machine and a color mark probe 22 arranged on the Z-shaped bracket 21. Among them, a mounting seat 221 is arranged on the Z-shaped bracket 21, and the color mark probe 22 is fixed on the mounting seat 221.
[0033] The marking component includes a lifting and rotating drive module 23 arranged on the Z-shaped bracket 21 and a marking pen 24 connected below the lifting and rotating drive module.
[0034] Before several die-cutting machines work, the operator rotates the Z-shaped bracket 21 so that the color mark probe 22 and the lifting and rotating drive component are located above the discharge end of the corresponding die-cutting machine. Specifically, several color mark probes 22 will simultaneously detect the moving material. If a color mark probe 22 detects that the color of the material is unqualified (the entire device will stop), the lifting and rotating drive module 23 will drive the marking pen 24 to descend and rotate to make a mark at the abnormal position. Thereafter, the operator will process the joint with the mark.
[0035] In order to control the entire device and quickly send an abnormal notice, this application further includes a controller and an alarm (this part of the content is not shown in this application). The color mark probe 22, the lifting and rotating drive module 23, and the alarm are all electrically connected to the controller. In specific implementation, if the color mark probe 22 detects a joint, it will control all die-cutting machines to stop working through the controller and the alarm will send an alarm signal. At this time, the lifting and rotating drive module 23 will drive the marking pen 24 to descend, so as to draw a mark at the abnormal position.
[0036] Exemplarily, the lifting and rotating drive module 23 of the present application includes a first cylinder 231 disposed within the Z-shaped bracket 21 and extending upward and downward, a first plate member 232 disposed inside the cylinder, a lead screw 233 rotatably disposed inside the first plate member 232 and extending downward, a second cylinder 234 inserted inside the first cylinder 231 and fixed to the lead screw nut 2331, a first bevel gear 235 connected to the lead screw 233 above the first plate member 232, a first rotating shaft 236 connected inside the first cylinder 231 above the first plate member 232, a first conical gear 237 mounted on the first rotating shaft 236 and meshing with the first bevel gear 235, a first reduction motor 238 disposed on the first cylinder 231 above the Z-shaped bracket 21 and connected to the first rotating shaft 236, a second plate member 3411 disposed below inside the second cylinder 234, a second rotating shaft 2342 rotatably disposed inside the second plate member 3411 and extending upward and downward, a disc 2347 connected to the second rotating shaft 2342 at the bottom of the second profiling cylinder, a second bevel gear 2343 connected to the first rotating shaft 236 above the second plate member 3411, a third rotating shaft 2344 connected inside the second cylinder 234 above the second plate member 3411, a second conical gear 2345 mounted on the third rotating shaft 2344 and meshingly connected to the second bevel gear 2343, and a second reduction motor 2346 connected to the third rotating shaft 2344 below the outside of the second cylinder 234; the marking pen 24 is disposed below the edge of the disc 2347.
[0037] When detecting an abnormality in the color mark probe 22, the first reduction motor 238 drives the first rotating shaft 236 to rotate, so that the first conical gear 237 drives the first bevel gear 235 to rotate. At this time, the lead screw 233 will drive the second cylinder 234 to descend and extend. When the marking pen 24 contacts the material joint, the second reduction motor 2346 drives the third rotating shaft 2344 to rotate, so that the second conical gear 2345 drives the second bevel gear 2343 to rotate. At this time, the second rotating shaft 2342 will drive the disc 2347 to rotate. In this way, the marking pen 24 located below the disc 2347 will draw a mark at the material joint.
[0038] In one specific embodiment, a rotary damper 211 is provided on the base of the die-cutting machine of the present application. The bottom of the Z-shaped bracket 21 is provided with a fourth rotating shaft 213 inserted inside the rotary damper 211. In this way, the operator can drive the Z-shaped bracket 21 to rotate so that the color mark probe 22 and the lifting and rotating drive module 23 are located above the corresponding die-cutting machine discharge end, and in specific use, the Z-shaped bracket 21 will not easily deflect, and the use effect is better.
[0039] In one specific embodiment, an annular step 23411 is integrally formed on the inner side below the second cylinder 234. An annular guide rail 234111 is provided below the annular step 23411, and the disc 2347 is slidably connected to the annular guide rail 234111.
[0040] In a preferred embodiment, in order to prevent the marking pen 24 of the present application from rapidly descending and causing damage to the pen tip, a pen barrel 25 is provided below the edge of the disc 2347 in the present application. A bottom sleeve 26 is screwed to the lower part of the pen barrel 25 through a threaded structure. A relief through groove 261 is formed in the middle of the bottom sleeve 26. The bottom sleeve 26 is provided with a plurality of latching grooves 262 in an annular array centered on the center of the relief through groove 261. A plurality of protrusions 241 are integrally provided below the marking pen 24. When the marking pen 24 is disposed inside the pen barrel 25, the plurality of protrusions 241 of the marking pen 24 are latched in the plurality of latching grooves 262 and the pen tip passes through the relief through groove 261. And a compression spring 27 is provided above the marking pen 24 and abuts against the pen barrel 25. When the marking pen 24 descends to contact the material and when the marking pen 24 is making a mark, the compression spring 27 can play an elastic supporting role. In this way, the marking pen 24 will not be easily damaged during rigid operation, and has a high use value.
