Description

Technical Field

[0001] This utility model relates to the field of laser printing technology, specifically to a laser QR code printing device. Background Technology

[0002] Laser-printed QR codes are based on the fundamental working mechanism of laser printing technology. Combining the graphic characteristics of QR codes (composed of alternating black and white rectangular modules), a high-contrast pattern is formed on the printing medium by a laser beam. To achieve traceability and management of special liquids throughout their entire lifecycle (such as production batches, ingredient information, storage conditions, etc.), clear and durable markings are required on the bottles containing them. As a high-density information storage carrier, QR codes have become an ideal marking choice because they can carry massive amounts of data and can be quickly read by smart devices.

[0003] A search revealed that patent application number 202120557830.X discloses a laser QR code printing device, comprising: a computer control device, a worktable, a laser engraving emitter, an air blowing unit, and a transmission unit. The transmission unit is mounted on the worktable, the laser engraving emitter is used to engrave QR codes on the workpiece transmitted by the transmission unit, the air blowing unit cooperates with the laser engraving emitter, and the air blowing unit blows air onto the workpiece. The computer control device is electrically connected to the laser engraving emitter, the air blowing unit, and the transmission unit respectively.

[0004] Although this laser QR code printing equipment adds an air blowing unit to existing laser QR code printing equipment to quickly blow away smoke, it is not convenient to fix the bottle being printed on. During the QR code printing process, the bottle is easily disturbed by external interference and shakes, which directly causes the laser beam to fail to accurately focus on the preset printing area. This results in the QR code pattern being offset, distorted, or even incomplete, ultimately causing the QR code printing to fail. This situation not only reduces production efficiency and increases production costs, but also may pose a potential threat to the storage safety of special liquids due to secondary printing operations.

[0005] Therefore, we propose a laser QR code printing device. Utility Model Content

[0027] Example 1:

After being purified by the smoke purifier body 51, it is discharged through the air outlet 52.

[0033] The working principle and usage process of this utility model: When using this laser QR code printing equipment, the bottle to be printed with a QR code is placed in the middle of the top surface of the transmission device 2. Then, the bottle is transported to the middle of the worktable 1 through the transmission device 2. After the bottle is transported to the middle of the worktable 1, the motor 34 is started to drive the bidirectional threaded rod 33 to rotate, which causes the sliders 35 at both ends to move closer to each other, so that the arc plate 39 clamps and fixes the bottle. Then, the electric push rod 43 is started to drive the moving block 44 and the laser engraving emitter 45 to move up and down, so that the height of the laser engraving emitter 45 is the same as the position on the bottle where the QR code needs to be printed. The QR code can then be printed on the bottle through the laser engraving emitter 45. During the printing process, the smoke purifier body 51 is started, and the smoke generated during printing enters the interior of the smoke purifier body 51 through the smoke hood 54 and the smoke pipe 53. After being purified by the smoke purifier body 51, it is discharged through the air outlet 52.
