[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When using this invention, start the pump to draw the release agent solution from the storage tank into the delivery pipe. The solution is then transported to the two grooves via the distribution pipe. Start the hydraulic rod to move the moving box upwards, moving the immersion box below the die-cutting blade. Start the cylinder to move the reinforcing plate downwards, then push the two die-cutting blades into the grooves to adhere to the release agent solution. As the cylinder contracts, the die-cutting blades return to their original position. Excess solution on the die-cutting blades is wiped away by the outer and inner sponge layers, preventing dripping and a messy work surface. The release agent provides lubrication and also isolates the static charge between the die-cutting blades and the PE plastic packaging, reducing the impact of static electricity on the die-cutting blades and the PE plastic packaging, preventing adhesion.

[0019] 2. When using this invention, start the fan to deliver air to the air supply pipe, then sequentially into the U-shaped pipe and two connecting pipes, and finally blow the air out through the air outlet pipe. At this time, the air blows straight down to both sides of the PE plastic packaging printed material, which applies pressure to both sides, making it easier for the PE plastic packaging printed material to maintain a flat state, which is more conducive to die-cutting. The positioning rod is embedded in the positioning plate to position the anti-stick component, so that the two U-shaped grooves are aligned with the two die-cutting blades respectively to achieve the positioning effect. By pulling the two insert rods upward, the die-cutting plate is slid out from the moving groove, which facilitates the moving box to move up and down in the movable hole.

[0020] 3. When using this invention, connect the ion air gun to a power source, turn on the power switch, and adjust the air speed adjustment knob to an appropriate position. The high-voltage ionized air generates ion air, which is blown onto the surface of the PE plastic packaging printed material. The positive and negative ions neutralize the static charge on the surface of the PE plastic packaging printed material, thereby eliminating static electricity and preventing static adhesion. Start the cylinder to push the die-cutting blade downward, and the PE plastic packaging printed material can be die-cut. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-9As shown, the present invention provides a technical solution: an intelligent die-cutting machine for PE plastic packaging printing, comprising: a processing table 1, an anti-stick component 4 at the bottom of the processing table 1, a frame 2 fixedly installed on the top of the processing table 1, a die-cutting component 5 inside the frame 2, a side pressure component 6 on the top of the frame 2, and a moving component 7 inside the processing table 1; the anti-stick component 4 includes a moving plate 401, a hydraulic rod 402 fixedly installed at the center of the top of the moving plate 401, and a moving component 7 fixedly installed on the top of the hydraulic rod 402. The movable box 403 has an immersion box 413 fixedly installed on its inner wall. The top of the immersion box 413 has two equidistant grooves 417. The top of the movable plate 401 near the rear surface is fixedly installed with a liquid pump 409. The output end of the liquid pump 409 is connected to a liquid delivery pipe 411 through a flange. One end of the liquid delivery pipe 411 is fixedly connected to a diverter pipe 412. The top of the movable plate 401 near one side is fixedly installed with a liquid storage tank 404. The input end of the liquid pump 409 is connected to a liquid extraction pipe 410 through a flange.

[0033] At the same time, according to Figures 1-3 , Figure 6 and Figure 8 As shown, a PLC controller 3 is bolted to one side of the outer surface of the frame 2. An outer sponge layer 415 is fixedly connected to one side of the inner wall of each of the two loop grooves 417, and an inner sponge layer 416 is fixedly connected to the other side of the inner wall of each of the two loop grooves 417. The two ends of the diversion pipe 412 are fixedly connected to the inside of the moving box 403 and the immersion box 413 respectively. One end of the liquid extraction pipe 410 is fixedly connected to the inside of the liquid storage tank 404. The PLC controller 3 can control the start and stop of other equipment. When the die-cutting blade 504 moves upward and resets, and leaves the loop groove 417, the excess release agent solution on the outer surface or inner wall of the die-cutting blade 504 can be wiped off by the wiping of the outer sponge layer 415 and the inner sponge layer 416, preventing the solution from dripping onto the processing table 1 and causing the table to become dirty.

[0034] according to Figures 1-3 As shown, a lid 405 is movably fitted onto the top of the storage tank 404. Multiple telescopic rods 407 are fixedly installed at the four corners of the top of the movable plate 401. Support springs 408 are movably fitted onto the outer surfaces of the multiple telescopic rods 407. One end of the multiple support springs 408 and one end of the multiple telescopic rods 407 are respectively fixedly installed at the four corners of the bottom of the movable box 403. The other end of the multiple support springs 408 is respectively fixedly installed at the four corners of the top of the movable plate 401. By opening the lid 405, it is convenient to pour the release agent solution into the storage tank 404. Then, the lid 405 is closed to prevent dust or other impurities from falling into the storage tank 404 and causing contamination of the release agent solution. The multiple telescopic rods 407 and support springs 408 provide auxiliary support for the movable box 403, improving the stability of the movable box 403's movement.

[0035] according to Figure 1 and Figures 3-5 As shown, two positioning rods 406 are fixedly installed on the top of the movable plate 401 near the front surface, and two positioning plates 8 are fixedly installed on the bottom of the processing table 1 near the front surface. The outer surfaces of the two positioning rods 406 near the top are respectively movably embedded in the interior of the two positioning plates 8. The width of the interior of the two positioning plates 8 matches the width of the outer surfaces of the two positioning rods 406. By embedding the positioning rods 406 in the interior of the positioning plates 8, the anti-stick component 4 can be positioned so that it is exactly below the movable hole 11. At this time, the two loop grooves 417 are respectively aligned with the two die-cutting blades 504, thereby achieving the positioning effect, which makes it easy for the subsequent die-cutting blades 504 to move accurately into the loop grooves 417.

[0036] according to Figures 5-6 and Figure 8 As shown, two drain pipes 414 are fixedly connected to the bottom of the immersion box 413. The interior of the two drain pipes 414 is connected to the interior of the two U-shaped grooves 417 respectively. One end of each drain pipe 414 is fixedly extended to the rear surface of the movable box 403. A valve 418 is provided on the outer surface of each drain pipe 414 near one end. By opening the two valves 418, the interior space of the drain pipe 414 becomes a flowable state, which facilitates the discharge of the release agent solution inside the two U-shaped grooves 417 through the drain pipe 414.

[0037] according to Figure 2 and Figure 7 As shown, the die-cutting assembly 5 includes a cylinder 501. The top of the cylinder 501 is fixedly installed on the top surface inside the frame 2. A reinforcing plate 502 is fixedly installed at the output end of the cylinder 501. Two die-cutting blades 504 are installed at the bottom of the reinforcing plate 502 by screws. Support rods 503 are fixedly installed at the four corners of the top of the reinforcing plate 502. The tops of the multiple support rods 503 extend movably through to the top of the frame 2. By activating the cylinder 501, the reinforcing plate 502 can be pushed downward, which in turn drives the two die-cutting blades 504 downward to perform die-cutting processing on PE plastic packaging printed materials. While the reinforcing plate 502 moves, the multiple support rods 503 slide up and down simultaneously, which improves the stability of the movement of the reinforcing plate 502 and reduces shaking.

[0038] according to Figure 7As shown, ion guns 9 are bolted to the top of the reinforcing plate 502 near the front and rear surfaces. The air outlets of the two ion guns 9 extend to the bottom of the reinforcing plate 502. The top of the reinforcing plate 502 near the front and rear surfaces has through holes matching the width of the air outlets of the ion guns 9. By connecting the ion guns 9 to a power source, turning on the power switch, and adjusting the wind speed knob to an appropriate position, ion wind is generated by high-voltage ionization of air. Positive and negative ions are evenly blown onto the surface of the PE plastic packaging printed material. The positive and negative ions neutralize the static charge on the surface of the PE plastic packaging printed material, thereby eliminating static electricity and preventing static adhesion.

[0039] according to Figure 2 and Figure 7 As shown, the side pressure assembly 6 includes a fan 601. An air supply pipe 602 is fixedly connected to the output end of the fan 601. A U-shaped pipe 603 is fixedly connected to one end of the air supply pipe 602. Connecting pipes 604 are fixedly connected to both ends of the U-shaped pipe 603. Multiple air outlet pipes 605 are fixedly connected to the outer surfaces of both connecting pipes 604. Multiple sliding holes 505 are provided on the top of the reinforcing plate 502 near the support rod 503. The outer surfaces of the multiple air outlet pipes 605 are movably embedded inside the multiple sliding holes 505. The outer surface of the fan 601 is fixedly mounted on the top of the frame 2 near the rear surface via an auxiliary plate. Both ends of the U-shaped tube 603 are fixedly inserted into the interior of the frame 2. Two support brackets 606 are fixedly installed on the outer surface of the U-shaped tube 603. The bottoms of the two support brackets 606 are fixedly installed on the top of the frame 2. By opening sliding holes 505, the reinforcing plate 502 can move up and down normally without being affected by the air outlet duct 605. The fan 601 is started to deliver air to the air supply duct 602, and then the air enters the U-shaped tube 603 and the two connecting pipes 604 in sequence. Finally, the air is blown out through the air outlet duct 605. Multiple air outlet ducts 605 are located on both sides of the two die-cutting blades 504, such as... Figure 1 As shown, when the air is blown out through the air outlet 605, it blows straight downwards towards both sides of the PE plastic packaging printed material, which puts pressure on both sides of the PE plastic packaging printed material, making it easier for the PE plastic packaging printed material to maintain a flat state, and is more conducive to die-cutting processing.

[0040] according to Figures 3-4 and Figure 9As shown, the movable component 7 includes a die-cutting plate 701. A square groove 702 is provided on the top of the die-cutting plate 701. A die-cutting pad 703 is provided inside the square groove 702. The width of the outer surface of the die-cutting pad 703 matches the width of the inside of the square groove 702. A movable groove 10 is provided on the top of the processing table 1. The outer surface of the die-cutting plate 701 is movably embedded in the movable groove 10. By pulling up the two insert rods 704, they are separated from the slot 705 and the insertion hole 12 in sequence. At this time, the die-cutting plate 701 is in a movable and fixed state. When the die-cutting plate 701 is slid out from the movable groove 10, the movable hole 11 is no longer blocked by the die-cutting plate 701, and the movable box 403 can move up and down.

[0041] according to Figures 3-4 and Figure 9 As shown, the bottom surface of the movable groove 10 has a movable hole 11. The top of the processing table 1 near the front surface has two insertion holes 12. Insert rods 704 are movably embedded in the two insertion holes 12. The top of the die-cutting plate 701 near the front surface has two slots 705. One end of each of the two insertion rods 704 is movably embedded in the two slots 705, which facilitates the subsequent sliding of the die-cutting plate 701 into the movable groove 10 and the insertion of the insertion rods 704 into the insertion holes 12 and slots 705. This can limit the die-cutting plate 701 and prevent it from accidentally shifting during subsequent processing, thus affecting the die-cutting process.

[0042] The overall mechanism and its working principle are as follows: When in use, the hydraulic rod 402, the liquid pump 409, the cylinder 501, the fan 601, and the PLC controller 3 are electrically connected. By turning on the external power supply of the PLC controller 3, the equipment is started. The PLC controller 3 can control the start and stop of other equipment. The bottom of the moving plate 401 is equipped with universal wheels with built-in brakes. The positioning rod 406 is embedded in the positioning plate 8, which can position the anti-stick component 4 so that it is exactly below the movable hole 11. At this time, the two loop grooves 417 are respectively aligned with the two die-cutting blades 504, thereby achieving the positioning effect, so that the subsequent die-cutting blades 504 can move accurately into the loop grooves 417. Between the outer sponge layer 415 and the inner sponge layer 416 A certain amount of space is left to allow the die-cutting blade 504 to pass through and enter the groove 417. The lid 405 is opened beforehand, and the release agent solution is poured into the storage tank 404. The lid 405 is then closed to prevent dust or other impurities from falling into the storage tank 404 and contaminating the release agent solution. The pump 409 is started via the PLC controller 3. Under the pressure of the pump 409, the pumping pipe 410 draws the release agent solution from the storage tank 404 into the delivery pipe 411, which then enters the diversion pipe 412. One end of the diversion pipe 412 is flush with the inner wall of the two grooves 417, so as not to affect the insertion of the die-cutting blade 504. The delivery pipe 411 is a flexible hose with a certain length to facilitate subsequent movement with the moving box 404. 3. Moving up and down, the diversion pipe 412 delivers the release agent solution to the two grooves 417 respectively. After the pump 409 has been working for a period of time, it will automatically stop. After injecting an appropriate amount of release agent solution into the two grooves 417, part of the release agent solution is absorbed by the outer sponge layer 415 and the inner sponge layer 416, and part of the release agent solution remains in the two grooves 417, completing the injection of the release agent solution. Then, the two insert rods 704 are pulled upwards, so that they leave the slot 705 and the insertion hole 12 in sequence. At this time, the die-cutting plate 701 is in a movable and fixed state. Slide the die-cutting plate 701 out of the moving groove 10. At this time, the moving hole 11 is no longer blocked by the die-cutting plate 701, and the moving box 403 can move up and down. Then, start the hydraulic rod 402 to push the moving box. 403 moves upward, passing through the movable hole 11 and the moving groove 10 to below the die-cutting blade 504. At this time, the hydraulic rod 402 automatically pauses for a period of time, and the cylinder 501 is activated to push the reinforcing plate 502 downward, causing the two die-cutting blades 504 to move downward and pass through the space between the outer sponge layer 415 and the inner sponge layer 416 into the recessed groove 417. This causes the bottom, outer surface, and inner wall of the die-cutting blade 504 to be covered with release agent solution. As the cylinder 501 contracts, the die-cutting blade 504 is reset and leaves the recessed groove 417. The outer sponge layer 415 and the inner sponge layer 416 wipe away the excess release agent solution on the outer surface or inner wall of the die-cutting blade 504, preventing the solution from dripping onto the processing table 1 and causing a mess.It can also reduce the waste of release agent solution. A layer of release agent solution is coated on the surface and inner wall of the die-cutting blade 504, which can accelerate the drying speed and prevent slow drying due to excessive solution. Then, the cylinder 501 is closed, and a period of time is waited for the release agent solution to dry. The release agent has a lubricating effect, which can reduce the coefficient of friction between the die-cutting blade 504 and the PE plastic packaging printing, reducing the friction between them. In addition, the release agent has a certain degree of conductivity, which can isolate the static charge between the die-cutting blade 504 and the PE plastic packaging printing, preventing the accumulation of static charge and thus reducing the impact of static electricity on the die-cutting blade 504 and the PE plastic packaging printing, preventing adhesion, and thus achieving an anti-adhesion effect. When the hydraulic rod 402 resumes operation, the moving box 403 is pulled back to its original position, and the die-cutting plate 701 is slid into the moving groove 10. Finally, the insert rod 704 is inserted into the insert hole 12 and slot 705 to limit the die-cutting plate 701 and prevent it from accidentally shifting during subsequent processing, which would affect the die-cutting process. The PE plastic packaging printed materials are conveyed to the die-cutting pad 703 by external conveying or winding equipment. The fan 601 is started to deliver air to the air supply pipe 602, which then enters the U-shaped pipe 603 and the two connecting pipes 604 in sequence. Finally, the air is blown out through the air outlet pipe 605. Multiple air outlet pipes 605 are located on both sides of the two die-cutting blades 504, such as... Figure 1 As shown, when the air is blown out through the air outlet 605, it blows straight downwards towards both sides of the PE plastic packaging print, applying pressure to both sides of the PE plastic packaging print, making it easier to keep the PE plastic packaging print flat and more conducive to die-cutting. The ion air gun 9 mainly consists of a high-voltage generator, air gun, ion needle, power cord, etc. Connect the ion air gun 9 to the power supply, turn on the power switch, and adjust the wind speed adjustment knob to an appropriate position. The high-voltage ionization of air generates ion wind, which blows positive and negative ions evenly onto the surface of the PE plastic packaging print. The positive and negative ions neutralize the static charge on the surface of the PE plastic packaging print, thereby eliminating static electricity and preventing static adhesion. Then, the cylinder 501 is activated, pushing the die-cutting blade 504 downwards to perform die-cutting on the PE plastic packaging print. This solves the problem of adhesion between the blade and the PE plastic packaging print during the use of the intelligent die-cutting machine for PE plastic packaging print, which affects the die-cutting effect and leads to poor quality of the PE plastic packaging print.

[0043] Among them, the hydraulic rod 402, the liquid pump 409, the cylinder 501, the fan 601, the ion gun 9 and the PLC controller 3 are all existing technologies, and their components and operating principles are all publicly available technologies, so they will not be explained in detail here.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
