[0002] With the increasing prevalence of automated equipment, more and more production tasks are using machines to replace manual operations; among them, tissue packaging machines are automated devices used to package tissues. Before the tissues are packaged, the plastic film used for packaging needs to be printed with identification codes such as the production date and batch number, and easy-tear lines need to be cut on the plastic film. Then, the labeled and pre-cut plastic film is wrapped onto the tissues.

[0003] In current tissue packaging production lines, marking and cutting are usually done by separate equipment, which has the following drawbacks:

[0004] 1. Large space occupation: Installing two machines side by side results in a bulky production line layout, which can only be used for some larger packaging machines and cannot be adapted to small packaging machines.

[0005] 2. Low collaborative efficiency: The membrane material needs to be positioned twice, which can easily lead to misalignment of the marking / cutting position, resulting in a high rate of defective products. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0026] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0027] To enable those skilled in the art to better understand 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.

[0028] like Figure 1-5As shown, a laser marking and cutting integrated device for a packaging machine includes a base 1 and a film fixing frame 2. The base 1 and the film fixing frame 2 are fixedly connected to the packaging machine. The film fixing frame 2 is used to lay the film, and the packaging machine can pull the film on the film fixing frame 2 to achieve continuous cutting and marking of the roll film.

[0029] A laser housing 3 is fixedly installed on the base 1. A cutting component and a marking component are provided inside the laser housing 3. A first light outlet 31 is provided on the laser housing 3 at a position corresponding to the cutting component, and a second light outlet 32 ​​is provided on the laser housing 3 at a position corresponding to the marking component. The first light outlet 31 and the second light outlet 32 ​​are respectively located directly above the film material fixing frame 2. The cutting component is used to cut easy-tear lines on the film material on the film material fixing frame 2, and the marking component is used to mark the film material on the film material fixing frame 2. During processing, the film material is laid on the film material holder 2. The packaging machine pulls the film material, moving the area to be cut to directly below the first light outlet 31 and the area to be marked to directly below the second light outlet 32. Then, the cutting component emits a laser, which passes through the first light outlet 31 and illuminates the film material, creating an easy-tear line. Simultaneously, the marking component emits a laser, which passes through the second light outlet 32 ​​and illuminates the film material, marking an identification code. After processing, the packaging machine pulls the film material away, simultaneously bringing the next sheet of film to the processing position, thus achieving continuous processing.

[0030] The membrane material fixing frame 2 is equipped with a membrane material adjustment mechanism, which can drive the membrane material to move on the membrane material fixing frame 2. The membrane material adjustment mechanism is used to tension and adjust the membrane material. During the processing, the position of the membrane material on the membrane material fixing frame 2 can be adjusted by the membrane material adjustment mechanism, so that different positions on the membrane material are aligned with the first light outlet 31 and the second light outlet 32, so as to meet the processing requirements of products of different types and sizes and improve the versatility of the equipment.

[0031] Specifically, such as Figure 3 As shown, multiple auxiliary rollers 4 are installed on the membrane material fixing frame 2. The auxiliary rollers 4 are rotatably connected to the membrane material fixing frame 2, and are used to lay the membrane material. During processing, the membrane material is stretched and laid onto each of the auxiliary rollers 4. The multiple auxiliary rollers 4 can tighten the membrane material, thereby laying it flat directly below the first light outlet 31 and the second light outlet 32, so that the cutting component and the marking component can process the membrane material.

[0032] The film material adjustment mechanism includes an adjustment shaft 5, on which an adjustment roller 6 is sleeved. 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 to the film material fixing frame 2. Under normal circumstances, the adjustment shaft 5 is limited to the film material fixing frame 2, and the roll of film material is laid on the adjustment roller 6. The packaging machine pulls the roll of film material to move, which can realize continuous processing. When changing the product type and needing to adjust the position of the film material, the adjustment shaft 5 can be driven to slide on the film material fixing frame 2, thereby pulling the film material on the film material fixing frame 2 and 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. After adjusting to the appropriate position, the adjustment shaft 5 can be fixed again.

[0033] In this embodiment, racks 7 are respectively installed on the left and right side walls of the film material fixing frame 2, and gears 8 are respectively installed on the adjusting shaft 5 at corresponding positions to the racks 7. The gears 8 are respectively meshed with the corresponding racks 7. One end of the adjusting shaft 5 extends out of the film material fixing frame 2, and an adjusting handwheel 9 is installed on the end extending out of the film material fixing frame 2. When adjustment is required, the adjusting handwheel 9 can be rotated to drive the gear 8 to rotate, and the gear 8 will move on the rack 7, thereby changing the position of the adjusting shaft 5 on the film material fixing frame 2. During the movement of the adjusting shaft 5, the adjusting 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.

[0034] A limiting block 10 is sleeved on the adjusting shaft 5, and the limiting block 10 is threadedly connected to the adjusting shaft 5. The limiting block 10 can abut against the membrane material fixing frame 2. Normally, the limiting block 10 is tightened to abut against the membrane material fixing frame 2, thereby limiting and fixing the adjusting shaft 5 to the membrane material fixing frame 2. When it is necessary to move the adjusting shaft 5, the limiting block 10 can be loosened first, so that the adjusting shaft 5 can be driven to move by rotating the adjusting handwheel 9. After adjusting to the appropriate position, the limiting block 10 is tightened again to abut against and fix it to the membrane material fixing frame 2.

[0035] 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 installed inside the laser housing 3. The output end of the first laser 11 is connected to the first galvanometer 12, and the laser emitted by the first laser 11 can irradiate the first galvanometer 12. The output end of the first galvanometer 12 is located at the corresponding position of the first light outlet 31. During operation, the laser emitted by the first laser 11 irradiates the first galvanometer 12, and then irradiates the first light outlet 31 through the first galvanometer 12. The laser will pass through the first light outlet 31 and irradiate the film on the film fixing frame 2, thereby cutting an easy-tear line on the film.

[0036] The first laser 11 generates heat during operation. To dissipate heat from the first laser 11, multiple cooling fans 13 are installed on the side wall of the first laser 11, and multiple heat dissipation holes 33 are provided on the side wall of the laser housing 3 at positions corresponding to the cooling fans 13. During operation, the cooling fans 13 carry away the heat from the first laser 11 and exhaust the hot air through the heat dissipation holes 33, thereby achieving the function of heat dissipation for the first laser 11.

[0037] 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 installed inside the laser housing 3. The output end of the second laser 14 is connected to the second galvanometer 15, allowing the laser emitted by the second laser 14 to illuminate the second galvanometer 15. The output end of the second galvanometer 15 is positioned at a corresponding location on the second light outlet 32. During operation, the laser emitted by the second laser 14 illuminates the second galvanometer 15, which then illuminates the second light outlet 32. The laser light passes through the second light outlet 32 ​​and illuminates the membrane material on the membrane material holder 2, thereby processing an identification code on the membrane material.

[0038] The second laser 14 generates heat during operation. To dissipate heat from the second laser 14, a water-cooling heat dissipation assembly is provided inside the second laser 14 in this embodiment. A water inlet connector 16 and a water outlet connector 17 are provided on the side wall of the second laser 14, and both the water inlet connector 16 and the water outlet connector 17 are externally connected to a chiller. Coolant is supplied to the second laser 14 through the external chiller, thereby achieving the purpose of heat dissipation for the second laser 14. The water-cooling heat dissipation assembly can adopt any existing structure; its specific structure will not be described in detail herein.

[0039] This integrated laser marking and cutting device combines marking and cutting components into a single unit, simplifying the mechanical structure and reducing the overall size of the equipment, making it suitable for use with 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 marking / cutting position misalignment, thus increasing the yield rate. On the other hand, an adjusting shaft 5 is provided on the film holder 2, allowing adjustment of the film's position on the holder 2, thereby adapting it to the processing needs of film materials of different sizes and enhancing the equipment's versatility.

[0040] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
