Description

Technical Field

[0001] This utility model relates to the field of laser marking machine technology, and in particular to a laser marking machine for packaging lines. Background Technology

[0002] A packaging line laser marking machine is an online marking device specifically designed for product packaging identification. It can print information such as production date, shelf life, batch number, and barcodes on product packaging according to user needs. This equipment uses laser technology for non-contact marking, enabling clear and permanent coding on products, including one-dimensional and two-dimensional barcodes, multi-line text, batch numbers, dates, trademarks, etc. Due to its high precision, high speed, non-contact marking, and energy-saving features, laser marking machines are widely used in various industries, as follows.

[0003] A search revealed patent CN221538511U, which discloses a laser marking device for packaging bags. The device includes a main frame, with support seats fixedly connected to the four corners of the lower surface of the main frame, and a power supply box fixedly connected to the center of the upper surface of the main frame. In this invention, by placing the packaging bag to be marked onto the work platform, the work frame is pushed into the main frame via a slide rail, and the sliding plate is lowered to reduce the impact of laser marking on manual operation. The automatic marking process enhances the device's practicality, efficiency, and quality. The high-speed laser marking adapts to the needs of high-speed production lines, improving production efficiency. It is also environmentally friendly, as the laser marking process eliminates the need for chemical solvents, inks, and other harmful substances, reducing pollution to the environment and operators, thus meeting environmental and health requirements. The laser marking device achieves precise positioning and printing, ensuring accurate marking.

[0004] As mentioned above, existing laser marking devices still have the following areas for optimization. For example, during operation, laser marking machines generate a large amount of smoke and dust. This smoke and dust mainly consists of particulate matter that volatilizes at high temperatures, of which more than 90% are visible to the naked eye, and the remainder diffuses in the air in gaseous form. This is because when a high-energy laser beam irradiates the surface of a material, it causes the material to melt, vaporize, ablate, or reach its ignition point rapidly. This causes the material surface to be instantly heated and transformed into gaseous or microparticles. This physical change process inevitably generates smoke and dust, which not only affects the processing environment but may also harm human health. For example, long-term inhalation of this smoke and dust may lead to respiratory diseases, especially since the harmful substances it contains may damage the lungs and other organs. During laser marking processing on packaging lines, a large number of outer packaging surfaces are laser marked in an assembly line manner, inevitably generating a large amount of smoke and dust that directly drifts into the nearby air, thus polluting the nearby working environment and endangering nearby workers. Therefore, there is an urgent need for a laser marking machine for packaging lines to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model discloses a laser marking machine for packaging lines. It features a processing mechanism that allows for the conveyor belt to transport packaged materials during operation, while the laser head of the laser marking machine marks the materials. During marking, a fan, in conjunction with the processing box and duct, generates negative pressure at the fume hood, promptly drawing the smoke and dust generated during laser marking into the processing box. Inside the processing box, interception filters and activated carbon filters effectively intercept and filter particulate matter and adsorb harmful substances, thus achieving excellent filtration and purification of the smoke and dust. Finally, the exhaust fan discharges relatively clean air, effectively preventing smoke and dust pollution and harm to nearby workers, significantly reducing safety hazards. In summary, this invention solves the problems in the background technology.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model discloses a laser marking machine for packaging lines, comprising a frame, a conveyor belt mechanism mounted on the top of the frame, two longitudinal grooves on the top of the frame, a base slidably mounted on the grooves, an L-shaped mounting seat fixedly connected to the top of the base, a hydraulic cylinder mounted through the top of the mounting seat, a lifting seat fixedly connected to the telescopic end of the hydraulic cylinder, a laser marking device mounted on the lifting seat, the laser marking device having a laser head extending through the lifting seat to the bottom of the lifting seat;

[0008] The processing mechanism includes an exhaust fan and a processing box, both of which are fixedly installed on the top of the lifting base. The exhaust end of the exhaust fan is connected to one side of the processing box. The processing box is equipped with an interception filter plate and an activated carbon filter plate. A duct is connected to the side of the processing box away from the exhaust fan. The bottom end of the duct passes through the lifting base and extends to the bottom of the lifting base. A fume hood is connected to the bottom end of the duct and is tilted towards the laser head.

[0009] An adjustment drive mechanism is located at the top of the frame.

[0010] Furthermore, the mounting base has multiple first reinforcing support blocks on the inner side of the L-shaped bend, and multiple second reinforcing support blocks at the connection between the mounting base and the base.

[0011] Furthermore, the top of the lifting seat is fixedly connected to multiple guide rods, the top ends of which movably pass through the top of the mounting seat.

[0012] Furthermore, the processing box is hinged to a door on the front, and the door is sealed to the processing box when closed.

[0013] Furthermore, the adjustment drive mechanism includes a fixed base and an electric actuator. The fixed base is fixedly installed on the top of the frame, and the electric actuator is fixedly installed through the fixed base. The telescopic end of the electric actuator is fixedly connected to one side of the back of the mounting base.

[0014] Furthermore, the bottom of the base fits into the top of the frame, and the bottom of the base is a smooth surface.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. This technical solution incorporates a processing mechanism that allows material packaging to be conveyed via a conveyor belt during operation. The laser head of the laser marking device then marks the packaging. During the marking process, a fan within the processing mechanism draws the generated smoke and dust into a processing box, where it is effectively filtered to remove particulate matter and adsorbed to remove harmful substances. Finally, relatively clean air is discharged, effectively preventing smoke and dust pollution and harm to nearby workers, significantly reducing safety hazards and demonstrating high practicality.

[0017] 2. This technical solution incorporates an adjustable drive mechanism, which allows the hydraulic cylinder and electric push rod to be activated during laser coding to adjust the horizontal height and forward / backward position of the laser head according to the size and coding position requirements of the packaging. This makes it suitable for coding various packaging sizes and allows coding to be performed at different locations on the packaging, further improving the practicality of the coding machine.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0028] Reference Figures 1-4 A laser marking machine for packaging lines includes a frame 1, a conveyor belt mechanism 2 installed on the top of the frame 1, two longitudinal grooves 3 on the top of the frame 1, a base 4 slidably installed at the grooves 3, an L-shaped mounting seat 5 fixedly connected to the top of the base 4, a hydraulic cylinder 6 installed through the top of the mounting seat 5, a lifting seat 7 fixedly connected to the telescopic end of the hydraulic cylinder 6, a laser marking device 8 installed at the lifting seat 7, and a laser head 10 provided by the laser marking device 8, which extends through the lifting seat 7 to the bottom of the lifting seat 7.

[0029] The processing mechanism 9 includes an exhaust fan 901 and a processing box 902. Both the exhaust fan 901 and the processing box 902 are fixedly installed on the top of the lifting base 7. The exhaust end of the exhaust fan 901 is connected to one side of the processing box 902. The processing box 902 is equipped with an interception filter plate 903 and an activated carbon filter plate 904. A duct 905 is connected to the side of the processing box 902 away from the exhaust fan 901. The bottom end of the duct 905 passes through the lifting base 7 and extends to the bottom of the lifting base 7. A smoke hood 906 is connected to the bottom end of the duct 905. The smoke hood 906 is inclined towards the laser head 10. The adjustment drive mechanism 11 is located on the top of the frame 1.

[0030] Multiple first reinforcing support blocks 12 are provided on the inner side of the L-shaped bend of the mounting base 5, and multiple second reinforcing support blocks 13 are provided at the connection between the mounting base 5 and the base 4; multiple guide rods 14 are fixedly connected to the top of the lifting seat 7, and the top of the guide rods 14 can move through the top of the mounting base 5; the front of the processing box 902 is hinged with a box door 907, and the box door 907 is sealed to the processing box 902 when closed.

[0031] In the specific implementation process, during operation, the material packaging can be conveyed by the conveyor belt mechanism 2, and the laser head 10 of the laser coding machine 8 can be used to code the material packaging. During the coding process, the operation of the exhaust fan 901, in conjunction with the processing box 902 and the duct 905, generates negative pressure suction at the fume hood 906, which promptly draws the smoke and dust generated during laser coding into the processing box 902. The smoke and dust are effectively filtered and purified by the interception filter plate 903 and the activated carbon filter plate 904 inside the processing box 902, thereby effectively filtering and purifying the particulate matter and adsorbing harmful substances. Finally, the exhaust fan 901 discharges relatively clean air, which can effectively prevent smoke and dust from polluting and harming nearby workers, and greatly reduce safety hazards.

[0032] Among them, the first reinforcing support block 12 and the second reinforcing support block 13 can improve the overall stability of the mounting base 5, making it less prone to shaking and affecting normal operation;

[0033] Among them, the guide rod 14 can improve the overall stability of the lifting seat 7, making it less likely to shake and affect normal operation;

[0034] The chamber door 907 can be opened periodically to clean the fixed dust particles in the treatment chamber 902, and the interception filter plate 903 and activated carbon filter plate 904 can be removed. The interception filter plate 903 can be cleaned, or the activated carbon filter plate 904 can be replaced. The chamber door 907 is sealed to the treatment chamber 902 when closed to prevent dust leakage. Specific Implementation Example 2:

[0036] Reference Figure 2 and Figure 5 In a preferred embodiment, the adjustment drive mechanism 11 includes a fixed base 1101 and an electric push rod 1102. The fixed base 1101 is fixedly installed on the top of the frame 1, and the electric push rod 1102 is fixedly installed through the fixed base 1101.

[0037] The bottom of the base 4 fits against the top of the frame 1, and the bottom of the base 4 is a smooth surface.

[0038] In the specific implementation process, when performing laser coding, the hydraulic cylinder 6 and the electric push rod 1102 can be activated according to the size requirements of the packaging and the coding position requirements. The extension and retraction of the hydraulic cylinder 6 can drive the lifting seat 7 to move up and down, thereby adjusting the horizontal height of the laser head 10 so that it can be used for coding of packaging of various sizes. The extension and retraction of the electric push rod 1102 can drive the mounting seat 5 to move back and forth in conjunction with the base 4 at the slide groove 3, thereby adjusting the front and back position of the laser head 10 so that coding can be performed at different positions on the packaging.

[0039] The bottom of the base 4 fits against the top of the frame 1 to improve the overall stability of the base 4 and the mounting base 5, while the bottom of the base 4 is a smooth surface to reduce wear and friction between the base 4 and the frame 1.
