Technical Field

[0001] This application relates to a laser engraving machine, belonging to the field of engraving equipment technology. Background Technology

[0002] Laser engraving machines are cylindrical and flatbed engraving devices designed for different types of products, such as embossing, gravure printing, micro-engraving, ceramic roller engraving, leather and rubber applications, etc.

[0003] The laser machine employs an advanced engraving control system, combined with a mature optical path control system and a stable mechanical design and structure, to ensure the production of high-quality laser cells and maintain the consistency of the dots.

[0004] Existing laser engraving machines use two sets of laser equipment when engraving rollers. The two sets of laser equipment are spliced ​​together to carry out the engraving work. The maximum power of each set of lasers is 700w, which has low working efficiency. There will be errors when the two sets of laser equipment are connected for engraving. The laser equipment is controlled by a lead screw, which results in limited precision. After engraving, chemical etching treatment is required.

[0005] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide a laser engraving machine to overcome the defects in the prior art. Utility Model Content

[0014] By adopting the above technical solution, the movable setting of the rotating device two enables the device to adapt to rollers of different lengths. The rotating device one and the rotating device two work together to fix the roller and drive the roller to rotate.

[0015] The laser engraving machine of this utility model is further configured such that: a folded dustproof cloth is installed on the rotating device 2, and the folded dustproof cloth is laid on the track on which the rotating device 2 moves.

[0016] By adopting the above technical solution, the folded dustproof cloth can unfold and compress together with the rotating device 2, preventing dust from falling into the track and affecting the movement of the rotating device 2.

[0017] The laser engraving machine of this utility model is further configured to include a water-cooled box, which is connected to the laser head.

[0018] By adopting the above technical solution, the water-cooled box can maintain the temperature of the laser head and avoid the laser head temperature from being too high, which would affect the working efficiency of the laser head.

[0019] The laser engraving machine of this utility model is further configured such that the power of each laser head is 1500w.

[0020] By adopting the above technical solution, the laser head has higher power and better engraving effect compared with the existing power.

[0021] The laser engraving machine of this utility model is further configured such that the machine base is made of marble.

[0022] By adopting the above technical solutions, marble is more stable, stress-free, and less prone to deformation compared to common castings.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The laser engraving machine of this invention uses multiple laser heads to overlap and engrave together to achieve a single depth, resulting in deeper engraving and higher engraving efficiency.

[0025] In this invention, multiple laser heads of the laser engraving machine move synchronously along the same track, enabling repeated engraving of the same part by different laser heads.

[0030] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 3 As shown, this utility model is a laser engraving machine. A fixing device 2 for fixing the printing roller is installed on the machine base 1, and the fixing device 2 can drive the printing roller to rotate. A laser device 3 is provided on the other side of the fixing device 2. The laser device 3 is slidably connected to the machine base 1 through a stepper motor. The laser device 3 is used to engrave the printing roller.

[0031] The fixing device 2 includes a rotating device 1 21 fixedly connected to the machine base 1 and a rotating device 22 slidably connected to the machine base 1. The position of the rotating device 1 21 corresponds to the position of the rotating device 22. The rotating device 1 21 and the rotating device 22 have the same structure. The rotating device 1 21 includes a turntable 211. The turntable 211 is provided with a plurality of clamping teeth 212. The plurality of clamping teeth 212 move synchronously on the turntable 211. The plurality of clamping teeth 212 are used to clamp the printing roller. The turntable 211 is rotated by a motor and drives the printing roller.

[0032] The laser device 3 is slidably connected to the base 1 via a stepper motor. The laser device 3 includes a laser frame 31, which houses two or more laser heads. The laser frame 31 drives the two or more laser heads to slide on the base 1. Multiple laser heads move along the same track, ensuring synchronized movement. Different laser heads can repeatedly engrave the same area. When multiple laser heads perform multiple engravings, they can collectively complete a single depth, resulting in greater depth and higher efficiency. The stepper motor displacement ensures high precision and more accurate engraving. Each laser head has a power of 1500W, which is higher than existing power standards, resulting in better engraving effects. In this embodiment, engraving of 1 square meter can be completed in six to seven minutes, with a resolution of approximately 2540. A water-cooled box 4 is connected to the laser head, maintaining a stable temperature. In this embodiment, the entire laser head is contained within the water-cooled box 4, which maintains a temperature of 20-25°C. This prevents water droplets on the lens from bursting during operation and avoids overheating of the laser head, which could affect its working efficiency.

[0033] A through slot is provided on the laser frame 31 for the laser head to emit laser light. A duct 32 is installed on the side of the through slot away from the laser head. The duct 32 is frustoconical. Inside the laser frame 31, there is a first air guide that blows the dust from inside the laser frame 31 out of the laser frame 31, preventing dust from staying on the laser head and affecting work efficiency. A second air guide 33 is installed outside the laser frame 31. The second air guide 33 blows the dust from the side of the duct 32 away from the laser head, preventing dust from staying on the duct 32 and affecting the work efficiency of the laser head.

[0034] The base 1 is made of marble. Compared with common castings, marble is more stable and stress-free, and less prone to deformation. A folded dustproof cloth 5 is installed on the rotating device 22. The folded dustproof cloth 5 is laid on the track on which the rotating device 22 moves. The folded dustproof cloth 5 can unfold and compress together with the rotating device 22 to prevent dust from falling into the track and affecting the movement of the rotating device 22.

[0035] The working principle of the laser engraving machine of this utility model is as follows:

[0036] First, place the printing roller between rotating device 1 21 and rotating device 22. Move rotating device 22 to a suitable position and start the clamping teeth 212 to clamp the printing roller. Start the motor to drive the turntable 211 and the printing roller to move. Multiple laser heads slide on the machine base 1 under the drive of stepper motors. Multiple laser heads perform multiple engravings to complete a depth together, making the engraving depth deeper and the efficiency higher. Remove the printing roller and directly form without chemical corrosion treatment.

[0037] The above-described specific embodiments are merely preferred embodiments of this invention and are not intended to limit this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
