[0016] Compared with the prior art, the invention has the following beneficial effects: the environmentally friendly laminated paper leakage prevention detection device can

[0017] (1) The present invention can effectively solve the problem that the existing laminated paper leakage prevention detection is mainly carried out by electrostatic conduction through the coordinated use of the detection device and the driven marking mechanism. Therefore, in order to prevent the laminated paper from being stained with dust after the detection, it is necessary to use an electrostatic elimination mechanism to remove the static electricity on the laminated paper, which results in high energy consumption and is not environmentally friendly. The power supply box conducts current to the laminated paper above it through the first conductive shell. When there is a hole in the laminated paper, the first conductive shell transmits the current to the second conductive shell through the hole in the laminated paper, so that the second conductive shell is charged to form a loop, and then the second motor connected to the loop is The electric heating rack is started, and the second motor drives the first lead screw and the second lead screw to rotate synchronously under the cooperation of the first belt transmission structure, so that the second slider connected below it pushes the movable plate and the marking sponge on the top of it to move upward along the electric heating rack guide to mark the coated paper on both sides of the hole, and the first slider drives the pressing plate to move downward along the electric heating rack guide to provide support for the mark of the marking sponge. The electric heating rack heats the marking sponge and the pressing plate during the guiding process, thereby increasing the drying speed of the ink mark, and thereby realizing the detection of the hole, and the coated paper after the detection does not need to remove static electricity, so that the detection process has low energy consumption and is more environmentally friendly;

[0018] (2) The present invention can effectively solve the problem that the existing ink is easy to solidify and stratify after being left for a long time, which affects the normal marking work. When the first motor drives the active roller to rotate to detect the coated paper, the active roller drives the stirring rod to drive the paddle to rotate through the first belt transmission structure to stir the ink in the ink storage tank to prevent it from stratifying. At the same time, when the electric heating rack heats the ink mark, it also heats the ink in the ink storage tank in the base, thereby further playing an anti-solidification role. In addition, the ink in the ink storage tank is in contact with the marking sponge when the marking sponge completes the mark reset, that is, the ink on the marking sponge is automatically replenished, thereby ensuring the normal marking work;

[0019] (3) The present invention can effectively solve the problem that the detection effect of the existing leakage detection device is easily affected by the dust and paper scraps on the surface of the coated paper through the coordinated use of the pretreatment mechanism and the first traction roller group. The second traction roller group and the first traction roller group both play the role of pulling the coated paper. The second traction roller group drives the cam to rotate synchronously when rotating and pulling the coated paper. When the convex point of the cam rotates and contacts the slide plate, it pushes the slide plate to compress the airbag, so that the gas inside the airbag enters the corresponding first air storage box and the interior of the second air storage box, and is sprayed onto the upper and lower surfaces of the coated paper through the nozzle above it, thereby achieving pre-dust removal, thereby preventing dust and paper scraps from affecting subsequent detection results, and preventing them from contaminating and adhering to the first conductive shell and the second conductive shell, thereby optimizing the structure of the device.

[0033] In a further embodiment, the driven marking mechanism 3 includes a second motor 301, a first lead screw 302, a second lead screw 303, a first slider 304, a pressure plate 305, a second slider 306, a movable plate 307 and a marking sponge 308, and the output end of the second motor 301 is connected to one end of the first lead screw 302, the first lead screw 302 is connected to the second lead screw 303 through a second belt transmission structure 309, and the first slider 304 and the second slider 306 are arranged on the first lead screw 302 and the second lead screw 303, and at the same time, the first slider 304 is connected to the pressure plate 305, the second slider 306 is connected to the movable plate 307, and the marking sponge 308 is arranged on the top of the movable plate 307.

[0034] In a further embodiment, the first slider 304 and the second slider 306 move in opposite directions, and the first slider 304 is disposed above the second slider 306 .

[0035] In a further embodiment, the driven marking mechanism 3 also includes a second belt transmission structure 309 and an electric heating rack 3010, and the electric heating rack 3010 is symmetrically arranged on the outside of the first slider 304 and the second slider 306, and the electric heating rack 3010 is slidably connected to the pressing plate 305 and the movable plate 307.

[0037] Specifically, in the actual working process, the coated paper to be inspected is first passed through the first traction roller group 4 and the inner side of the pretreatment mechanism 6, that is, the coated paper is pulled from right to left by the first traction roller group 4 and the pretreatment mechanism 6, and the pretreatment mechanism 6 performs pre-dust removal on the coated paper. After the dust removal, the coated paper continues to move, and the first motor 209 drives the first conductive shell 204 and the second conductive shell 205 to rotate in the opposite direction under the cooperation of the gear transmission structure 208 to pull the coated paper, and the coated paper moved below it is inspected for leaks. The power supply box 203 conducts current to the laminated paper above it through the first conductive shell 204. When there is a hole in the laminated paper, the first conductive shell 204 transmits current to the second conductive shell 205 through the hole in the laminated paper, so that the second conductive shell 205 is charged to form a loop. Then the second motor 301 and the electric heating rack 3010 connected to the loop are started. The second motor 301, in cooperation with the first belt transmission structure 2012, synchronously drives the first lead screw 302 and the second lead screw 303 to rotate synchronously, so that the second lead screw 302 and the second lead screw 303 under the cooperation of the first belt transmission structure 2012 can rotate synchronously. The second slider 306 connected to the right side pushes the moving plate 307 and the marking sponge 308 on the top thereof to move upward to mark the coated papers on both sides of the hole. At the same time, the first slider 304 drives the pressing plate 305 to move downward to provide support for the marking of the marking sponge 308. At the same time, the second slider 306 and the first slider 304 will be heated when moving along the electric heating rack 3010. The heated marking sponge 308 and the pressing plate 305 can make the ink dry quickly when marking the ink. After the marking is completed, the second motor 301 rotates in the opposite direction, so that the first slider 304 can rotate in the opposite direction. The second slider 306 and the first slider 304 move in the same direction and reset. At this time, the marking sponge 308 is stored in the ink storage tank inside the base 1 and contacts the ink, so as to realize automatic ink addition. The electric heating frame 3010 immersed in the ink storage tank heats the ink synchronously when heating the second slider 306 and the first slider 304. The active roller 201 drives the stirring rod 2010 and the paddle 2011 to rotate and stir the ink in the ink storage tank through the first belt transmission structure 2012 to prevent the ink from being stratified and condensed.

[0038] When there are no holes in the coated paper, the current of the first conductive shell 204 cannot be transmitted to the second conductive shell 205 due to its insulating properties, so the loop cannot be closed, the second motor 301 and the electric heating rack 3010 will not be triggered, and the coated paper continues to be transported to the left and is pulled to the external winding device for winding through the first traction roller group 4. Example

[0039] This embodiment is a further description of the above embodiment. It should be understood that this embodiment includes all the aforementioned technical features and is further described in detail.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, in a further embodiment, the pretreatment mechanism 6 includes a first air storage box 601, a second air storage box 602, a nozzle 603, an air bag 604, a slide plate 605, a cam 606, a one-way air intake valve 607, a dust cover 608 and a second traction roller group 609, and the first air storage box 601 and the second air storage box 602 are arranged on both sides of the second traction roller group 609. At the same time, the first air storage box 601 and the second air storage box 602 are both provided with a one-way air intake valve 607 and a dust cover 608, and the dust cover 608 is engaged at the air inlet of the one-way air intake valve 607. The first air storage box 601 and the second air storage box 602 are both connected to the slide plate 605 through the air bag 604, and the side walls of the first air storage box 601 and the second air storage box 602 are both provided with nozzles 603.

[0041] In a further embodiment, the air jet head 603 on the first air storage box 601 is located below the laminated paper, the air jet head 603 on the second air storage box 602 is located above the laminated paper, and a one-way exhaust valve is provided on the air jet head 603 .

[0042] In a further embodiment, a cam 606 is disposed on the inner side of the slide plate 605 , and the cam 606 is disposed on the second traction roller set 609 .

[0043] In a further embodiment, the second traction roller set 609 and the first traction roller set 4 are both mounted on the frame 7;

[0044] Specifically, the second traction roller group 609 drives the cam 606 to rotate synchronously while rotating and traction of the coated paper. When the convex point of the cam 606 rotates and contacts the slide plate 605, the slide plate 605 is pushed to compress the airbag 604, so that the gas inside the airbag 604 enters the corresponding first air storage box 601 and the second air storage box 602, and is sprayed to the upper and lower surfaces of the coated paper through the nozzle 603 above them, thereby achieving pre-dust removal, thereby preventing dust and paper scraps from affecting subsequent detection results, and at the same time preventing them from contaminating and adhering to the first conductive shell 204 and the second conductive shell 205. Similarly, when the convex point of the cam 606 rotates away from the slide plate 605, the slide plate 605 is no longer compressed and is pushed by the airbag 604 to slide and reset along the frame 7. At this time, the external airflow is filtered by the dust cover 608 and automatically filled into the interior of the airbag 604 through the one-way air inlet valve 607, providing an air source for the next dust removal.
