Description

Technical Field

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

[0002] In the food packaging industry, laser marking technology is widely used for marking production dates, batch numbers, QR codes, and other information on various packaging containers due to its advantages such as being non-contact, requiring no consumables, and providing clear and durable markings. Walnut oil, as a high-value-added healthy edible oil, requires high precision and clarity in its markings, as well as a clean production environment, during its packaging process.

[0003] In existing walnut oil packaging production lines, fixed or semi-automatic laser coding equipment is commonly used, which typically presents the following problems: First, the high temperature of the laser acting on the surface of the packaging material during coding easily generates smoke and volatiles. If not cleaned in time, these can adhere to the packaging surface or the optical components of the equipment, affecting coding quality and equipment stability. Second, traditional equipment lacks an effective integrated dust removal structure and relies mostly on external independent dust collection devices, resulting in a scattered layout, low dust collection efficiency, and inconvenient maintenance. Third, the coding devices are mostly open structures, posing safety hazards such as laser radiation leakage and accidental contact with moving parts by operators. Fourth, the coding position is inconvenient to adjust, making it difficult to adapt to the flexible coding needs of different sized packaging bottles.

[0004] Therefore, it is necessary to design a laser coding device for walnut oil packaging to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0020] Example: Laser coding device for walnut oil packaging, such as Figures 1-4As shown, the system includes a bracket 1, a pulley assembly 2, a mounting platform 3, a baffle 4, a protective frame 5, an electric guide rail 6, a sliding block 7, a laser marking device 8, an exhaust fan 9, a corrugated pipe 10, an adapter frame 11, a dust hood 12, a controller 15, a camera 13, a display screen 14, a filter cover 16, and a filter element 17. The pulley assembly 2 is positioned between the left and right sides of the upper part of the bracket 1. The mounting platform 3 is bolted to the rear of the bracket 1. Baffles 4 are bolted to the front and rear sides of the top of the bracket 1, located around the pulley assembly 2. A vertically mounted electric guide rail 6 is mounted on the top of the mounting platform 3. The sliding block 7 is slidably connected to the electric guide rail 6 and can move up and down along the guide rail. The laser marking device 8 is fixed to the sliding block 7, allowing for adjustable marking height. The protective frame 5 is fixed to the top of the mounting platform 3 and the bracket 1, and also connects the electric guide rail 6 and... The non-working side of the laser-engraved dock 8 is covered to form a semi-enclosed protective cover. An exhaust fan 9 is installed on the top of the protective frame 5. A corrugated pipe 10 is connected to the suction side of the exhaust fan 9. An adapter frame 11 is bolted to the top of the laser-engraved dock 8. A dust collection hood 12 is connected and communicated to the front of the adapter frame 11. The corrugated pipe 10 passes through the protective frame 5 and is sealed to the top of the adapter frame 11. A controller 15 is installed on the front of the bracket 1. A camera 13 is installed on the upper part of the dust collection hood 12. A display screen 14 is bolted to the left side of the protective frame 5. A filter cover 16 is unclamped on the top of the exhaust fan 9. A filter element 17 is placed between the suction inlet of the exhaust fan 9 and the filter cover 16 and can be replaced by opening the filter cover 16. The pulley assembly 2, the electric guide rail 6, the laser-engraved dock 8, the exhaust fan 9, the display screen 14, and the camera 13 are all electrically connected to the controller 15.

[0021] The walnut oil packaging container is placed on the pulley assembly 2 and conveyed into the coding station via the pulley assembly 2. The controller 15 activates the electric guide rail 6, which is a vertically mounted ball screw type electric linear module, including a servo motor, a ball screw pair, and a high-precision linear guide rail. The sliding block 7 is fixed on the moving slide of the module. The servo motor drives the ball screw to rotate, causing the sliding block to move up and down along the guide rail, thereby achieving precise adjustment of the height of the laser marking terminal 8. This electric linear module is a commercially available standard part, such as the HIWIN-KAA series, THK-RSR series, or similar products. It drives the sliding block 7 to move vertically along the guide rail, adjusting the vertical height of the laser marking terminal 8 relative to the packaging container, achieving alignment of the coding areas for different sizes of packaging bottles, and realizing precise positioning coding. When the laser marking terminal 8 is working, it laser-marks the packaging surface, generating smoke and particulate matter in the process.

[0022] The exhaust fan 9 starts synchronously, and the dust collection hood 12 forms a negative pressure zone at the front end of the laser marking dock 8, which sucks the dust generated by marking into the interior of the transfer frame 11. The dust is then guided through the corrugated pipe 10 to the exhaust outlet of the exhaust fan 9, realizing the immediate suction of dust in the work area, preventing equipment contamination and affecting the clarity of marking. The dust collection hood 12 is fixed in position with the laser marking dock 8 and moves synchronously with the sliding block 7 to ensure that the suction range always covers the marking area.

[0023] The protective frame 5 covers the non-working side of the electric guide rail 6 and the laser marking dock 8, forming a semi-enclosed shield to prevent personnel from accidentally touching moving parts or laser radiation, thus improving operational safety. The camera 13 captures images of the marking area and transmits them to the controller 15 for recognition and quality inspection. If necessary, the marking status can be displayed in real time on the display screen 14 for easy monitoring by operators.

[0024] The filter cover 16 can be opened, and the filter element 17 is located between the suction inlet of the exhaust fan 9 and the filter cover 16. The filter element 17 can be replaced by opening the filter cover 16 periodically, which is convenient for maintenance. The baffle 4 restricts the lateral displacement of the packaging container during the conveying process, ensuring that it enters the coding area stably. The entire device is uniformly coordinated and controlled by the controller 15 to realize the integrated operation of automatic conveying, positioning, coding, dust removal and monitoring.
