Technical Field
[0001] This utility model relates to the technical field of vacuum color coating processing equipment, and in particular to a punching device for vacuum color coating processing. Background Technology
[0002] Vacuum-coated color film is widely used in high-end packaging fields such as food, pharmaceuticals, and cosmetics. During the production process, in order to ensure precise alignment in subsequent printing, lamination, or bag-making processes, it is usually necessary to punch holes on the edge or at specific locations of the film material as positioning holes for optical tracking. Traditional punching methods are mostly offline mechanical punching, which has problems such as low production efficiency and the fact that the debris generated by punching can easily contaminate the surface of the film material. Especially in the vacuum coating environment where the cleanliness requirements are extremely high, debris contamination can seriously affect the quality of the coated product.
[0003] In existing technologies, although there are online drilling devices, most of them adopt simple stamping structures, resulting in incomplete debris removal and limited drilling efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a punching device for vacuum coating color film processing. It realizes the punching of multiple positioning holes in one go and simultaneously. This parallel operation mode greatly improves the punching efficiency. It is thorough in dust removal and has a rapid response. It fundamentally solves the biggest technical obstacle of mechanical stamping in a vacuum environment - the problem of debris contamination. It can effectively solve the problems in the background technology.
[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution: A punching device for vacuum coating of colored film includes a frame, an arc-shaped frame fixed to the inner side of the frame, a multi-punch head drive mechanism mounted on the arc-shaped frame, a plurality of punch heads fixed on the movable part of the multi-punch head drive mechanism, a conveyor roller rotatably connected to the inner side of the frame via a rotating shaft, the conveyor roller being hollow inside, punching holes evenly distributed on the conveyor roller, bushings fixed inside the punching holes, the punching holes corresponding to the punch heads, and the punching holes communicating with the interior of the conveyor roller, a dust removal unit mounted on the side of the frame communicating with the interior of the conveyor roller, and a PLC controller mounted on the side of the frame, the PLC controller being electrically connected to an external power supply.
[0006] Furthermore, the arc-shaped frame is coaxially arranged with the conveyor roller, and an arc-shaped baffle is fixed on the frame at the bottom position corresponding to the conveyor roller. The arc-shaped baffle is slidably arranged in contact with the surface of the conveyor roller.
[0007] Furthermore, the multi-press head drive mechanism includes a servo motor, a transmission frame, a guide rod, and a bidirectional lead screw. The bidirectional lead screw is rotatably mounted on the inner side of the frame, the servo motor is mounted on the side of the frame, the output shaft of the servo motor is fixedly connected to the end of the bidirectional lead screw, the end of the guide rod is fixedly connected to the frame, the transmission frame is slidably connected to the guide rod, the transmission frame is threadedly connected to the bidirectional lead screw, and the servo motor is electrically connected to a PLC controller.
[0008] Furthermore, the multi-press head drive mechanism also includes a first hinge, a connecting rod, and a second hinge. One end of the connecting rod is hinged to the transmission frame via the first hinge, and the second hinge is hinged to the other end of the connecting rod.
[0009] Furthermore, the multi-press head drive mechanism also includes a slide bar, a guide groove, and a transmission rod. The guide groove is evenly opened on the arc-shaped frame. The slide bar is slidably connected to the guide groove. The end of the slide bar is hinged to the end of the connecting rod through a second hinge. One end of the transmission rod is fixedly connected to the slide bar, and the other end of the transmission rod is fixedly connected to the press head.

[0010] Furthermore, the dust removal unit includes a suction pipe, a vacuum cleaner, and a rotary joint. The vacuum cleaner is installed on the side of the frame. The suction pipe is fixed to one end of the conveying roller and communicates with the inside of the conveying roller. The other end of the suction pipe is rotatably connected to the suction port of the vacuum cleaner through the rotary joint. The vacuum cleaner is electrically connected to a PLC controller.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This drilling device for vacuum coating color film processing has the following advantages: 1. By setting up a multi-punch head drive mechanism that is synchronously controlled by a single drive source, the punching of multiple positioning holes can be completed at one time and simultaneously. This parallel operation mode greatly improves the punching efficiency and is especially suitable for high-speed continuous vacuum coating production lines, effectively avoiding the production bottlenecks caused by traditional single-head punching or offline processing.

Detailed Implementation
[0015] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.
[0016] Please see Figure 1-4 This embodiment provides a technical solution: a punching device for vacuum coating color film processing, including a frame 1, an arc-shaped frame 7 fixed on the inner side of the frame 1, a multi-punch head drive mechanism 5 installed on the arc-shaped frame 7, a plurality of punch heads 8 fixed on the movable part of the multi-punch head drive mechanism 5, a conveyor roller 2 rotatably connected to the inner side of the frame 1 through a rotating shaft 6, the conveyor roller 2 is hollow inside, punching holes 9 are evenly opened on the conveyor roller 2, a bushing 10 is fixed inside the punching hole 9, the punching hole 9 is correspondingly arranged with the punch head 8, the punching hole 9 is connected to the inside of the conveyor roller 2, a dust removal unit 4 is installed on the side of the frame 1, the dust removal unit 4 is connected to the inside of the conveyor roller 2, and a PLC controller 11 is installed on the side of the frame 1, the PLC controller 11 is electrically connected to an external power supply.
[0017] The arc frame 7 is coaxially arranged with the conveyor roller 2. An arc baffle 3 is fixed on the frame 1 at the bottom position corresponding to the conveyor roller 2. The arc baffle 3 is slidably arranged in contact with the surface of the conveyor roller 2. The arc baffle 3 can prevent debris from escaping from the bottom of the conveyor roller 2.
[0018] The multi-press head drive mechanism 5 includes a servo motor 51, a transmission frame 52, a guide rod 53, and a bidirectional lead screw 54. The bidirectional lead screw 54 is rotatably mounted on the inner side of the frame 1. The servo motor 51 is mounted on the side of the frame 1. The output shaft of the servo motor 51 is fixedly connected to the end of the bidirectional lead screw 54. The end of the guide rod 53 is fixedly connected to the frame 1. The transmission frame 52 is slidably connected to the guide rod 53 and threadedly connected to the bidirectional lead screw 54. The servo motor 51 is electrically connected to the PLC controller 11. The multi-press head drive mechanism 5 also includes a first hinge 58, a connecting rod 59, and a second hinge 510. One end of the connecting rod 59 is connected to the transmission frame 54 via the first hinge 58. 2. The second hinge 510 is hinged to the other end of the connecting rod 59. The multi-punch head drive mechanism 5 also includes a slide bar 55, a guide groove 56 and a transmission rod 57. The guide groove 56 is evenly opened on the arc frame 7. The slide bar 55 is slidably connected to the guide groove 56. The end of the slide bar 55 is hinged to the end of the connecting rod 59 through the second hinge 510. One end of the transmission rod 57 is fixedly connected to the slide bar 55, and the other end of the transmission rod 57 is fixedly connected to the punch head 8. The transmission rod 57 is slidably connected to the arc frame 7. The external unwinding equipment transports the vacuum-coated color film to this device. The film passes through the gap between the conveying roller 2 and the punch head 8 and is pulled by the external winding equipment. When the area on the film material requiring perforation moves to the stamping station, the winding and unwinding equipment pauses (intermittent operation) or operates according to specific instructions. Under program control, the PLC controller 11 starts the servo motor 51. The output shaft of the servo motor 51 drives the bidirectional lead screw 54 to rotate. The bidirectional lead screw 54 is threadedly connected to the transmission frame 52. The transmission frame 52 slides along the guide rod 53. Through a linkage mechanism consisting of the first hinge 58, connecting rod 59, and second hinge 510, the linear motion of the transmission frame 52 is converted into the radial sliding of multiple slide bars 55 along the guide groove 56 of the arc-shaped frame 7. All drive rods 57 and punch heads 8 are pushed synchronously toward the conveyor roller 2. The punch head 8 penetrates the film material and inserts into the punch hole 9 of the conveyor roller 2 to complete a one-time multi-hole punching. It can realize the synchronous and smooth punching and retraction of all punch heads 8. By setting up a multi-punch head drive mechanism 5 that is synchronously controlled by a single drive source, the punching of multiple positioning holes can be completed at one time and synchronously. This parallel operation mode greatly improves the punching efficiency, and is especially suitable for high-speed continuous vacuum coating production lines, effectively avoiding the production bottlenecks caused by traditional single-head punching or offline processing.
[0019] The dust removal unit 4 includes a suction pipe 41, a vacuum cleaner 42, and a rotary joint 43. The vacuum cleaner 42 is mounted on the side of the frame 1. The suction pipe 41 is fixed to one end of the conveyor roller 2 and communicates with the inside of the conveyor roller 2. The other end of the suction pipe 41 is rotatably connected to the suction port of the vacuum cleaner 42 through the rotary joint 43. The vacuum cleaner 42 is electrically connected to the PLC controller 11. The debris generated by the stamping is instantly sucked into the stamping hole 9 under the negative pressure generated by the vacuum cleaner 42, and then passes through the inside of the conveyor roller 2, the suction pipe 41, and the rotary joint 43. Ultimately, the dust is collected in the dust bag of the vacuum cleaner 42. The rotary joint 43 ensures that the suction pipe 41 remains unobstructed when the conveying roller 2 rotates. It combines the hollow conveying roller 2 with the integrated dust removal unit 4. By using vacuum suction to directly remove the debris from the stamping hole 9 (i.e., the source of debris generation) at the moment of stamping, it achieves "instant cleaning after production". This source treatment method is thorough in dust removal and responds quickly, fundamentally solving the biggest technical obstacle of mechanical stamping in a vacuum environment - the problem of debris contamination.
[0020] The working principle of the punching device for vacuum coating film processing provided by this utility model is as follows: The external unwinding equipment transports the vacuum coating film to this device. The film material passes through the gap between the conveying roller 2 and the punching head 8 and is pulled by the external winding equipment. When the part of the film material that needs to be punched moves to the punching station, the unwinding and winding equipment pauses intermittent work or runs according to specific instructions. The PLC controller 11 first starts the vacuum cleaner 42, and then starts the servo motor 51 under program control. The output shaft of the servo motor 51 drives the bidirectional lead screw 54 to rotate. The bidirectional lead screw 54 is threadedly connected to the transmission frame 52. The transmission frame 52 slides along the guide rod 53. The transmission frame 52 converts the linear motion into multiple slide bars 55 sliding radially along the guide groove 56 of the arc frame 7 through the linkage mechanism composed of the first hinge 58, the connecting rod 59 and the second hinge 510. This pushes all the transmission rods 57 and the punching head 8 to punch towards the conveying roller 2 simultaneously. The punching head 8 penetrates the film material and inserts into the punching hole 9 of the conveying roller 2 to complete the one-time multi-hole punching. The debris generated during stamping is instantly sucked into the stamping hole 9 by the negative pressure generated by the vacuum cleaner 42. It is then collected in the dust bag of the vacuum cleaner 42 through the inside of the conveying roller 2, the vacuum pipe 41 and the rotary joint 43. After stamping is completed, the servo motor 51 reverses and drives the stamping head 8 to return to its original position. The film material continues to be conveyed and enters the next working cycle.
[0021] It is worth noting that the components disclosed in the above embodiments are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The PLC controller 11, servo motor 51 and vacuum cleaner 42 are all products currently on the market. Their structures and principles are public knowledge. This solution only describes their role in this solution and the technical effects to be produced. Both the vacuum cleaner 42 and the servo motor 51 are controlled by the PLC controller 11. During operation, the PLC controller 11 sends a start signal to the vacuum cleaner 42 before or at the same time as sending a drive signal to the servo motor 51, so that the debris generated by the stamping can be sucked up in time. After the stamping action is completed, the vacuum cleaner 42 is controlled to turn off.
