It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1-5 As shown, a laser marking and cutting integrated device for a packaging machine includes a machine base 1 and a film material fixing frame 2. The machine base 1 and the film material fixing frame 2 are respectively fixedly connected to the packaging machine. The film material fixing frame 2 is used to lay the film material, and the packaging machine can pull the film material to move on the film material fixing frame 2, thereby realizing continuous cutting and marking of the roll film material.

[0030] A laser cover 3 is fixedly mounted on the machine base 1, and a cutting assembly and a marking assembly are arranged inside the laser cover 3. A first light outlet 31 is provided on the laser cover 3 at a position corresponding to the cutting assembly, and a second light outlet 32 is provided on the laser cover 3 at a position corresponding to the marking assembly. The first light outlet 31 and the second light outlet 32 are respectively located directly above the film material fixing frame 2. The cutting assembly is used to cut a tear line on the film material on the film material fixing frame 2, and the marking assembly is used to mark the film material on the film material fixing frame 2. During processing, the film is laid onto the film material fixing frame 2, and the packaging machine pulls the film material to move, pulling the location on the film material that needs to be cut to directly below the first light outlet 31, and pulling the location on the film material that needs to be marked to directly below the second light outlet 32. Then, the cutting component works to emit a laser, which passes through the first light outlet 31 and irradiates the film material, thereby processing an easy-to-tear line on the film material. At the same time, the marking component works to emit a laser, which passes through the second light outlet 32 and irradiates the film material, marking the film material with an identification code. After processing, the packaging machine pulls the film away and simultaneously pulls the next film material to the processing position, thereby realizing a continuous processing operation process.

[0031] The film material holder 2 is equipped with a film material adjustment mechanism that drives the film material to move on the holder 2. This mechanism is used to tension and adjust the film material. During processing, the film material position on the holder 2 can be adjusted by the film material adjustment mechanism, so that different positions on the film material are aligned with the first light outlet 31 and the second light outlet 32. This meets the processing requirements of products of different types and sizes and improves the versatility of the equipment.

[0032] Specifically, if Figure 3 As shown, multiple auxiliary rollers 4 are mounted on the film material holder 2, rotatably connected to the holder 2. Each auxiliary roller 4 is used to lay the film material. During processing, the film material is stretched and laid onto each auxiliary roller 4. The multiple auxiliary rollers 4 tighten the film material, laying it flat directly below the first and second light outlets 31, 32, allowing the cutting and marking components to process the film.

[0033] The film material adjustment mechanism includes an adjustment shaft 5, on which an adjustment roller 6 is sleeved, and the adjustment roller 6 can rotate freely on the adjustment shaft 5. The adjustment shaft 5 extends into the film material fixing frame 2 and is slidably limited and connected to the film material fixing frame 2. Under normal circumstances, the adjustment shaft 5 is limitedly connected to the film material fixing frame 2, and the rolled film material is laid on the adjustment roller 6. The rolled film material is pulled by the packaging machine to move, and continuous processing can be achieved. When the product type is changed and the film material position needs to be adjusted, the adjustment shaft 5 can be driven to slide on the film material fixing frame 2, thereby pulling the film on the film material fixing frame 2, changing the alignment of the film material with the first light outlet 31 and the second light outlet 32, so that other positions of the film material are aligned with the first light outlet 31 and the second light outlet 32. When it is adjusted to the appropriate position, the adjustment shaft 5 can be re-fixed.

[0034] In this embodiment, racks 7 are mounted on the left and right side walls of the film material holder 2, and gears 8 are mounted on the adjustment shaft 5 at positions corresponding to the racks 7. The gears 8 are meshed with the corresponding racks 7. One end of the adjustment shaft 5 extends out of the film material holder 2, and an adjustment handwheel 9 is mounted on the end extending out of the film material holder 2. When adjustment is required, the adjustment handwheel 9 is turned to drive the gear 8 to rotate, and the gear 8 will move on the rack 7, thereby changing the position of the adjustment shaft 5 on the film material holder 2. During the movement of the adjustment shaft 5, the adjustment roller 6 will pull the film material to move, so that different positions of the film material are aligned with the first light outlet 31 and the second light outlet 32.

[0035] A limit block 10 is sleeved on the adjustment shaft 5 and is threadedly connected to the adjustment shaft 5. The limit block 10 can abut against the membrane material fixing frame 2. Under normal circumstances, the limit block 10 is tightened to abut against the membrane material fixing frame 2, thereby limiting and fixing the adjustment shaft 5 to the membrane material fixing frame 2. When it is necessary to push the adjustment shaft 5 to move, the limit block 10 can be loosened first, so that the adjustment shaft 5 can be driven to move by turning the adjustment handwheel 9. After adjusting to the appropriate position, the limit block 10 can be tightened again to abut against the membrane material fixing frame 2.

[0036] like Figure 4-5 As shown, the cutting assembly includes a first laser 11 and a first galvanometer 12. The first laser 11 and the first galvanometer 12 are respectively fixedly mounted in the laser housing 3. The output end of the first laser 11 is connected to the first galvanometer 12. The laser light emitted by the first laser 11 can be irradiated onto the first galvanometer 12. The output end of the first galvanometer 12 is arranged at a position corresponding to the first light outlet 31. During operation, the first laser 11 emits laser light to irradiate the first galvanometer 12, and then irradiates the first light outlet 31 through the first galvanometer 12. The laser light will pass through the first light outlet 31 and irradiate the film material on the film material fixing frame 2, thereby cutting a tear line on the film material.

[0037] The first laser 11 generates heat during operation. To dissipate heat from the first laser 11, multiple cooling fans 13 are mounted on the sidewalls of the first laser 11. Multiple cooling holes 33 are provided on the sidewalls of the laser housing 3 at positions corresponding to the cooling fans 13. During operation, the cooling fans 13 dissipate the heat generated by the first laser 11 and discharge the hot air through the cooling holes 33, thereby dissipating heat from the first laser 11.

[0038] The marking assembly includes a second laser 14 and a second galvanometer 15. The second laser 14 and the second galvanometer 15 are respectively fixedly mounted in the laser housing 3. The output end of the second laser 14 is connected to the second galvanometer 15. The laser light emitted by the second laser 14 can be irradiated onto the second galvanometer 15. The output end of the second galvanometer 15 is set at a position corresponding to the second light output port 32. During operation, the second laser 14 emits laser light to irradiate the second galvanometer 15, and then irradiates the second light output port 32 through the second galvanometer 15. The laser light will pass through the second light output port 32 and irradiate the film material on the film material fixing frame 2, thereby processing an identification code on the film material.

[0039] The second laser 14 generates heat during operation. To dissipate this heat, a water-cooling heat dissipation assembly is provided within the second laser 14 in this embodiment. A water inlet connector 16 and a water outlet connector 17 are provided on the sidewalls of the second laser 14. Each of these connectors is connected to an external water chiller. Cooling liquid is supplied to the second laser 14 via the external water chiller, thereby dissipating heat from the second laser 14. The water-cooling heat dissipation assembly can employ any existing structure, and its specific structure is not described in detail herein.

[0040] This integrated laser marking and cutting device integrates the marking and cutting components into a single device, simplifying the device's mechanical structure and reducing its overall size, making it suitable for use in small packaging machines. Furthermore, during processing, the film only needs to be positioned once to complete the processing of the tear line and identification code, significantly improving processing efficiency and reducing the problem of marking / cutting position offset, thereby increasing the processing yield rate. Furthermore, an adjustment shaft 5 is provided on the film holder 2, which can adjust the position of the film on the holder 2, making it suitable for processing films of different sizes and improving the versatility of the device.

[0041] The above-mentioned specific implementation is a preferred implementation of the present invention, and is not intended to limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to this specific implementation. All equivalent changes made in accordance with the present invention are within the scope of protection of the present invention.
