[0030] Anti-counterfeiting patterns can be generated by computer software or designed by staff. The anti-counterfeiting patterns are composed of dots (i.e., the shape of vent holes). The batch number of the product and the anti-counterfeiting pattern are registered and filed. Vent holes that can form the above-mentioned anti-counterfeiting pattern are punched on the film paper 1 by the punching device 2. The film paper 1 can not only tightly wrap the product (in this embodiment, it is a packaging box; in other embodiments, it can be the product itself), but also play an anti-counterfeiting role based on the anti-counterfeiting pattern formed by the vent holes.

[0031] End caps are threaded to both sides of the abutment platform 14. A support shaft 16 passes through each end cap, and the support shaft 16 and end caps are rotatably connected. The abutment platform 14 can rotate around the support shaft 16 under the abutment of the film paper 1. In other embodiments, multiple perforation devices 2 can be used. The specific position of the drive block 17 on the support shaft 16 corresponds to the abutment area between the film paper 1 and the abutment platform 14. The vent holes punched on the film paper 1 can be combined to form an anti-counterfeiting pattern. The pressure roller 10 is located on both sides of the perforation component 13, enabling it to tightly press the film paper 1 against the abutment platform 14. The drive component of the film paper 1, the bagging assembly 3, the sealing and cutting assembly 4, the shrinking assembly 5, and the product conveying assembly 6 are all existing technologies and will not be described in detail.

[0032] like Figure 2 and Figure 3 As shown, the abutment platform 14 is circumferentially provided with an installation groove 18 along its length. An installation strip 19 is provided in the installation groove 18. The installation strip 19 is arranged with first through holes 24 for the exhaust needle 23 to pass through along its own length. The first through hole 24 is connected to a receiving chamber 21. The receiving chamber 21 is composed of the installation strip 19 and a fixing plate 22. A perforating component 25 is elastically provided in the receiving chamber 21. The perforating component 25 includes an exhaust needle 23 and a mounting component 26 for fixing the exhaust needle 23. One end of the mounting component 26 is inserted with the exhaust needle 23, and the other end of the mounting component 26 passes through a second through hole 27 provided on the fixing plate 22. The side of the mounting component 26 that passes through the second through hole 27 can be pressed by the driving block 17 during the rotation of the abutment platform 14. The mounting component 26 can slide in the installation groove 18 to drive the exhaust needle 23 to perforate the film paper 1.

[0033] The installation groove 18 and the installation strip 19 are circumferentially arranged on the abutting table 14. The film paper 1 abuts against the abutting table 14 and drives the abutting table 14 to rotate. The abutting table 14 presses the installation piece 26 during rotation. The installation piece 26 can slide in the installation groove 18 to drive the air exhaust needle 23 to punch the film paper 1. During the punching process, the air exhaust needle 23 follows the rotation of the abutting table 14, extends out of the abutting table 14 to punch and retracts into the installation strip 19 to complete the punching. The synchronous movement of the film paper 1 and the air exhaust needle 23 avoids the tangential pulling of the film paper 1 by the air exhaust needle 23 during the punching, ensures the regularity of the air exhaust hole and avoids the film paper 1 from being wrinkled.

[0034] The installation strip 19 and the installation groove 18 are correspondingly provided with matched clamping blocks and are threadedly connected by bolts. The fixed plate 22 and the installation strip 19 are also threadedly connected, which is firm and convenient to disassemble and assemble.

[0035] As shown in Figure 4 and Figure 5 , the installation piece 26 comprises an installation cylinder 28. The installation cylinder 28 is provided with an internal groove 29 for inserting the air exhaust needle 23. The installation cylinder 28 is provided with a rolling groove 30 at the side away from the opening. The rolling groove 30 is rollingly provided with a sliding ball 31. The outside of the rolling groove 30 is provided with a first through groove 32. The first through groove 32 is provided with a first spring 33. The first through groove 32 and the installation groove 18 are connected through a sliding groove 35. The outside of the installation cylinder 28 is fixedly provided with a limiting block 34. The limiting block 34 and the sliding groove 35 are slidingly connected. The limiting block 34 extends into the first through groove 32 and abuts against the first spring 33.

[0036] During the rotation of the abutting table 14, the driving block 17 can slide and press the installation piece 26 to move the installation piece 26 along the radial direction of the abutting table 14. The design of the rolling groove 30 and the internal sliding ball 31 can significantly reduce the friction and reduce the wear of the installation piece 26 and the driving block 17 during abutting, thereby prolonging the service life. When the installation piece 26 is pressed by the driving block 17, the cooperation of the limiting block 34 and the sliding groove 35 limits the sliding direction of the installation piece 26. When the air exhaust needle 23 is pushed out, the limiting block 34 extrudes the first spring 33. When the abutting table 14 no longer applies pressure to the installation piece 26 during rotation, the first spring 33 drives the installation piece 26 to reset, and the air exhaust needle 23 retracts into the containing chamber 21.

[0037] As shown in Figure 5 , the opening side of the internal groove 29 is fixedly provided with a cap 36. The cap 36 is connected with an elastic card 37 in the internal groove 29. The air exhaust needle 23 is provided with a mounting clamping groove 38 corresponding to the elastic card 37. The elastic card 37 can be clamped into the mounting clamping groove 38 to fix the air exhaust needle 23.

[0038] The top of the elastic card 37 is fixedly connected to the cap 36. The cap 36 and the mounting cylinder 28 can be fixedly connected or threadedly connected. The elastic card 37 includes an extension 39 that abuts against the inner wall of the built-in groove 29 and a fixing arc ring 40 formed by the extension 39 protruding inward. The fixing arc ring 40 can deform under force during the insertion and removal of the exhaust needle 23. When installing the exhaust needle 23, the fixing arc ring 40 can engage 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 removal of the exhaust needle 23.

[0039] The drive block 17 is fixedly mounted on the support rod. The drive block 17 extends along the length of the abutment platform 14. The abutment surface between the drive block 17 and the punched part 25 is arc-shaped.

[0040] like Figure 5 As shown, the exhaust needle 23 has a double-pointed structure, and there are two mounting slots 38 on the exhaust needle 23, which are symmetrically arranged at both ends of the exhaust needle 23.

[0041] The exhaust pin 23 can be inserted into the built-in slot 29 by inserting, unplugging and inverting it, so that the worn end of the exhaust pin 23 during the drilling process can be inserted into the built-in slot 29, and the end that was originally placed in the slot without drilling can be turned outward. The operation of inserting, unplugging and inverting the exhaust pin 23 is relatively simple and does not require professional tools or skills, making equipment maintenance more convenient.

[0042] A flexible pad 41 is provided on the bottom wall of the built-in groove 29. This is to prevent excessive force from being applied when inserting or removing the exhaust pin 23, which could cause the exhaust pin 23 to directly impact the bottom wall of the built-in groove 29 at one end and damage the pointed end of the exhaust pin 23. The flexible pad 41 can be made of rubber.

[0043] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
