Description

Technical Field

[0001] The invention belongs to the technical field of packaging anti-counterfeiting, and in particular relates to a packaging box plastic sealing anti-counterfeiting process and a device thereof. Background Art

[0002] In the existing card packaging production technology field, the plastic film of the card packaging box is either transparent or a film with a logo. The latter has a certain anti-counterfeiting property compared to the former, but the distribution of the logo is irregular and the anti-counterfeiting performance is poor. The existing card packaging box is packaged by a heat sealing and cutting machine, which includes feeding, sealing and cutting, and heat shrinking stages. Before the sealing and cutting stage, the card packaging box needs to be fed into the plastic film. The plastic film needs to be punched in advance. After the plastic film is sealed, a certain amount of air may remain in the bag. Punching vents can effectively release the air and prevent the air from occupying the space and affecting the tightness and aesthetics of the packaging. For example, in the Chinese patent with the publication number CN212448307U, a film feeding and punching mechanism of a fully automatic plastic sealing machine is disclosed. The punching mechanism on the heat sealing and cutting machine in the prior art is only a single punching function. Therefore, an anti-counterfeiting process and a device combined with the anti-counterfeiting process are proposed here. Summary of the invention

[0054] Step 1: Generate an anti-counterfeiting pattern randomly through computer software, and record the anti-counterfeiting pattern and the products of this batch;

[0055] Step 2: using a punching device 2 to set vent holes on the film paper 1 used for packaging products, and a plurality of vent holes can be arranged to form an anti-counterfeiting pattern;

[0056] Step 3: Bagging: the product to be packaged is covered with the film paper 1 having the anti-counterfeiting pattern (composed of vent holes) through the bagging component 3 and the conveying component 6;

[0057] Step 4: Sealing and cutting, heating and sealing the film paper 1 through the sealing and cutting component 4;

[0058] Step 5: Heat and shrink, and shrink the film paper 1 through the shrinking component 5 to shrink and tightly wrap it on the surface of the product;

[0059] Step 6: Cooling and quality inspection: cool the product, then check whether the film paper 1 packaging of the product is complete and whether the anti-counterfeiting pattern on the film paper 1 is clear.

[0060] The exhaust needle 23 in the punching device 2 can be sharpened by a sharpening device to restore its sharpness.

[0061] The anti-counterfeiting pattern can be generated by computer software or designed by the staff. The anti-counterfeiting pattern is composed of dots (i.e., the shape of the exhaust holes). The batch number of the product and the anti-counterfeiting pattern are registered and filed. The exhaust holes that can form the above-mentioned anti-counterfeiting pattern are punched on the film paper 1 by the punching device 2. This can not only make the film paper 1 tightly pack the product (the packaging box in this embodiment, and the product itself in other embodiments), but also play an anti-counterfeiting role according to the anti-counterfeiting pattern composed of the exhaust holes.

[0062] like Figure 2-7 As shown, the punching device of the above-mentioned plastic sealing anti-counterfeiting process of the packaging box is also included. The punching device 2 includes a support plate 7, a support roller 8 is arranged on the support plate 7, and a reel 9 is supported by the support roller 8. A film 1 for packaging is wound on the reel 9. A pressure roller 10, a guide roller 11 and a punching component 13 are arranged on the support plate 7. The pressure roller 10 can press the film 1 through the punching component 13 to punch holes. The punching component 13 includes a cylindrical abutment platform 14, and a punching member 25 is elastically arranged in the abutment platform 14. The abutment platform 14 is coaxial with the abutment platform 14. A support shaft 16 is rotatably connected, and the support shaft 16 and the support plate 7 are fixedly connected. The support shaft 16 is connected to a driving block 17 on the inner side of the abutment platform 14, wherein the abutment platform 14 rotates driven by the film paper 1, and the punching piece 25 in the abutment platform 14 is pressed and extended out of the abutment platform 14 by the driving block 17, and the film paper 1 abutting through the abutment platform 14 is punched. The exhaust needles 23 are arranged in a circular array, and the exhaust needles 23 in the punching piece 25 can be plugged in and out to ensure that the exhaust holes punched on the film paper 1 can form an anti-counterfeiting pattern.

[0063] The abutment platform 14 is threadedly connected with end caps on both sides, and the end caps pass through a support shaft 16. The support shaft 16 and the end caps are rotatably connected, and the abutment platform 14 can rotate around the support shaft 16 under the abutment of the film paper 1. In other embodiments, there can be multiple punching devices 2, and the specific position of the driving block 17 on the support shaft 16 is set according to the abutment area of ​​the film paper 1 and the abutment platform 14. The exhaust holes punched on the film paper 1 can be combined into an anti-counterfeiting pattern. The pressure roller 10 is arranged on both sides of the punching component 13, and the film paper 1 can be tightly pressed against the abutment platform 14. The driving component of the film paper 1, the bagging component 3, the sealing and cutting component 4, the shrinking component 5 and the product conveying component 6 are all prior art, so they are not elaborated.

[0064] like Figure 3 and Figure 4 As shown, the abutment platform 14 is provided with a mounting groove 18 circumferentially along the length direction, and a mounting strip 19 is provided in the mounting groove 18. The mounting strip 19 is provided with a first through hole 24 for the exhaust needle 23 to pass through in an array along its own length direction, and the first through hole 24 is connected to the accommodating chamber 21, and the accommodating chamber 21 is composed of the mounting strip 19 and the fixing plate 22. A punching piece 25 is elastically provided in the accommodating chamber 21, and the punching piece 25 includes an exhaust needle 23 and a mounting piece 26 for fixing the exhaust needle 23. The exhaust needle 23 is inserted into one end of the mounting piece 26, and the other end of the mounting piece 26 passes through a second through hole 27 provided on the fixing plate 22. The side of the mounting piece 26 passing through the second through hole 27 can be pressed by the driving block 17 during the rotation of the abutment platform 14, and the mounting piece 26 can slide in the mounting groove 18 to drive the exhaust needle 23 to punch the film paper 1.

[0065] The mounting groove 18 and the mounting strip 19 are arranged on the circumference of the abutment platform 14, and the film paper 1 abuts against the abutment platform 14 and drives the abutment platform 14 to rotate. The abutment platform 14 presses the mounting member 26 during the rotation, and the mounting member 26 can slide in the mounting groove 18 to drive the exhaust needle 23 to punch holes in the film paper 1. During the punching process, the exhaust needle 23 follows the rotation of the abutment platform 14, extends out of the abutment platform 14 to punch holes, and retracts into the mounting strip 19 to complete the punching. The synchronous movement of the film paper 1 and the exhaust needle 23 avoids the film paper 1 being tangentially pulled by the exhaust needle 23 during punching, thereby ensuring the regularity of the exhaust holes and avoiding wrinkles on the film paper 1.

[0066] The mounting strip 19 and the mounting groove 18 are correspondingly provided with matching snap-fitting protrusions and are threadedly connected by bolts. The fixing plate 22 and the mounting strip 19 are also threadedly connected, so that the fixing is reliable and the disassembly and assembly are convenient.

[0067] like Figure 4As shown, the mounting member 26 includes a mounting cylinder 28, which is provided with a built-in groove 29 for inserting the exhaust needle 23, a rolling groove 30 is provided on the side of the mounting cylinder 28 away from the opening, a sliding ball 31 is rollingly provided in the rolling groove 30, a first through groove 32 is provided outside the accommodating groove, a first spring 33 is provided in the first through groove 32, the first through groove 32 and the mounting groove 18 are connected by a sliding groove 35, a limit block 34 is fixedly sleeved on the outside of the mounting cylinder 28, the limit block 34 and the sliding groove 35 are slidably connected, the limit block 34 extends into the first through groove 32 and abuts against the first spring 33.

[0068] During the rotation of the abutment platform 14, the driving block 17 can produce sliding pressure on the mounting member 26, pushing the mounting member 26 to move along the radial direction of the abutment platform 14. The design of the rolling groove 30 and the internal sliding ball 31 allows the sliding ball 31 to roll and abut on the surface of the driving block 17 during abutment, which can significantly reduce friction, reduce the wear of the mounting member 26 and the driving block 17, and extend the practical life. When the mounting member 26 is pressed by the driving block 17, the sliding direction of the mounting member 26 is limited by the cooperation of the limit block 34 and the sliding groove 35. When the exhaust needle 23 is pushed out, the limit block 34 squeezes the first spring 33. When the abutment platform 14 no longer applies pressure to the mounting member 26 during the rotation, the first spring 33 drives the mounting member 26 to reset, and the exhaust needle 23 retracts into the accommodating chamber 21.

[0069] like Figure 5 As shown, a cap 36 is fixedly provided on the opening side of the built-in groove 29, and the cap 36 is connected to an elastic card 37 in the built-in groove 29. The exhaust needle 23 is provided with an installation slot 38 corresponding to the elastic card 37, and the elastic card 37 can be inserted into the installation slot 38 to fix the exhaust needle 23.

[0070] The top of the elastic card 37 is fixedly connected to the cap 36. The cap 36 and the mounting tube 28 can be fixedly connected or threadedly connected. The elastic card 37 includes an extension portion 39 abutting against the inner groove wall of the built-in groove 29 and a fixed arc ring portion 40 formed by the inward protrusion of the extension portion 39. The fixed arc ring portion 40 can be deformed by force during the insertion and removal of the exhaust needle 23. When installing the exhaust needle 23, the fixed arc ring portion 40 can be engaged with the mounting slot 38 on the exhaust needle 23 to fix the exhaust needle 23. The exhaust needle 23 is a consumable, which facilitates the installation and disassembly of the exhaust needle 23.
