Description

Technical Field

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

[0002] Laser marking machines are software-controlled devices that mark products using a non-contact method. However, existing food laser marking devices often have certain problems, such as:

[0003] Application number CN202322330426.0, entitled "A Laser Marking Device," includes a support frame mounted on a conveying device; a marking gun passing through the support frame and positioned downwards; a lifting plate located at the inner end of the support frame, maintaining its vertical movement and fixed to the marking gun; and pressure cylinders located at both ends of the marking gun and rotatably mounted on the lifting plate. The rotation direction of the pressure cylinders is consistent with the conveying direction of the conveying device. During operation, this laser marking machine uses the laser at the marking point to etch the surface of the material, leaving permanent marks. However, the high temperature of the laser generates smoke and debris that permeates the air, causing environmental pollution and harming the physical and mental health of workers if not cleaned, thus failing to meet daily needs. Therefore, a food laser marking device is proposed to solve these problems. Utility Model Content

[0006] The above technical solution facilitates efficient laser coding and cleaning maintenance of food packaging.

[0007] As a preferred embodiment of this utility model, a conveyor belt is fitted onto the first roller, and the first roller is connected to the second roller via the conveyor belt; the right end of the first rotating shaft passes through the right end face of the box and the left end face of the vacuum chamber.

[0008] The above technical solution facilitates continuous transport of food packaging via conveyor belt, thereby improving coding efficiency.

[0009] As a preferred embodiment of this utility model, a drive gear is mounted on the first rotating shaft located inside the vacuum chamber; a third rotating shaft is connected to the bearing on the inner wall of the left end of the vacuum chamber, and a driven gear is mounted on the third rotating shaft.

[0010] By adopting the above technical solution, it is easy to realize air circulation and dust removal in the vacuum chamber through the gear transmission system, further enhancing the practicality and ease of maintenance of the device.

[0011] As a preferred embodiment of this utility model, a limiting post is fitted on the right end of the third rotating shaft, and the upper end face of the limiting post is connected to the bearing on the top surface of the vacuum chamber.

[0012] The above technical solution facilitates the stable operation of the No. 3 rotating shaft and prevents it from shifting or shaking during high-speed rotation.

[0013] As a preferred embodiment of this utility model, the first rotating shaft and the third rotating shaft are driven by the meshing of the driving gear and the driven gear; the number of teeth of the driven gear is greater than that of the driving gear.

[0014] By adopting the above technical solution, when the No. 3 rotating shaft drives the fan blades to rotate, it can generate sufficient centrifugal force to suck the dust into the dust collection box.

[0015] As a preferred embodiment of this utility model, a filter screen is fixedly connected to the left end face of the dust collection box, and the filter screen is only for air circulation; a fan blade is fixedly connected to the right end of the No. 3 rotating shaft, and a one-way ventilation window is fixedly connected to the upper end face of the vacuum chamber.

[0016] The above technical solution facilitates the formation of an effective air circulation mechanism within the vacuum chamber, which promptly absorbs dust and fine particles generated during the laser marking process, maintaining a clean and hygienic working environment.

[0017] As a preferred technical solution of this utility model, a tensioning wheel assembly is fixedly connected at the horizontal center of the inner wall surface on the left side of the box, and the tensioning wheel assembly is located between the first roller and the second roller.

[0018] The above technical solution helps to ensure the stability and tightness of the conveyor belt during long-term operation and prevents transmission failures caused by slackness or excessive tightness.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the device simultaneously realizes the conveying of food and timely absorption of the smoke and debris generated during the aurora printing process through a single power source, thereby significantly improving production efficiency and printing accuracy; in addition, the device has a compact design, occupies little space, and is easy to integrate into existing production lines.

[0020] 1. When in use, start the dual-axis motor. The dual-axis motor drives the first rotating shaft to rotate, the first rotating shaft drives the first roller to rotate, and the first roller drives the second roller to rotate through the conveyor belt. The packaged food on the conveyor belt is continuously transported to the area directly below the laser marking machine. Then the laser marking machine laser prints on the outer packaging of the food.

[0021] 2. At the same time, the No. 1 rotating shaft drives the No. 3 rotating shaft to rotate through the meshing of the driving gear and the driven gear. Since the number of teeth of the driving gear is less than the number of teeth of the driven gear, the speed of the No. 3 rotating shaft is greater than the speed of the No. 1 rotating shaft, thereby accelerating the rotation of the fan blades and continuously expelling the air in the vacuum chamber, thereby creating a negative pressure in the vacuum chamber. The smoke and debris generated during the food aurora coding process are sucked into the dust collection box through the air pipe. Attached Figure Description

A dual-axis motor 6 is connected, and a first rotating shaft 8 is fixedly connected to the shaft end of the dual-axis motor 6; the left end face of the first rotating shaft 8 is connected to the bearing on the inner wall of the left end of the box 1, and a first roller 7 is mounted on the first rotating shaft 8; a second rotating shaft 10 is connected to the bearing on the right end face of the box 1, and the left end of the second rotating shaft 10 is connected to the bearing on the inner wall of the left end of the box 1; the second rotating shaft 10 is located at the rear end of the first rotating shaft 8, and a second roller 11 is mounted on the second rotating shaft 10, which facilitates efficient laser coding and cleaning maintenance of food packaging;

[0030] A conveyor belt 9 is fitted on roller 7, and roller 7 is connected to roller 11 via conveyor belt 9; the right end of shaft 8 passes through the right end face of box 1 and the left end face of vacuum chamber 4, which facilitates continuous transmission of food packaging via conveyor belt 9 and improves coding efficiency.

[0031] A drive gear 12 is mounted on the first rotating shaft 8 located inside the vacuum chamber 4; a bearing is connected to the third rotating shaft 14 on the inner wall of the left end of the vacuum chamber 4, and a driven gear 13 is mounted on the third rotating shaft 14, which facilitates the air circulation and dust cleaning inside the vacuum chamber 4 through the gear transmission system, further enhancing the practicality and ease of maintenance of the device.

[0032] The right end of the No. 3 rotating shaft 14 is fitted with a limiting post, and the upper end face of the limiting post is connected to the bearing on the top surface of the vacuum chamber 4, which facilitates the stable operation of the No. 3 rotating shaft 14 and prevents it from shifting or shaking when rotating at high speed.

[0033] The No. 1 rotating shaft 8 and the No. 3 rotating shaft 14 are driven by the meshing of the driving gear 12 and the driven gear 13; the number of teeth of the driven gear 13 is greater than that of the driving gear 12, so that when the No. 3 rotating shaft 14 drives the fan blade 15 to rotate, it can generate enough centrifugal force to suck the dust into the dust collection box 17.

[0034] A filter 16 is fixedly connected to the left end of the dust collection box 17, and the filter 16 is only for air circulation; a fan blade 15 is fixedly connected to the right end of the third rotating shaft 14, and a one-way ventilation window 19 is fixedly connected to the upper end of the vacuum chamber 4, which facilitates the formation of an effective air circulation mechanism in the vacuum chamber 4, and timely absorbs the dust and fine particles generated during the laser marking process, so as to maintain the cleanliness and hygiene of the working environment.

[0035] A tensioning wheel assembly 20 is fixedly connected at the horizontal center of the inner wall on the left side of the housing 1. The tensioning wheel assembly 20 is located between the first roller 7 and the second roller 11, which helps to ensure the stability and tightness of the conveyor belt 9 during long-term operation and prevents transmission failures caused by slackness or excessive tension.

[0037] At the same time, the No. 1 rotating shaft 8 drives the No. 3 rotating shaft 14 to rotate through the meshing of the driving gear 12 and the driven gear 13. Since the number of teeth of the driving gear 12 is less than the number of teeth of the driven gear 13, the rotation speed of the No. 3 rotating shaft 14 is greater than that of the No. 1 rotating shaft 8, thereby accelerating the rotation of the fan blade 15 and continuously expelling the air in the vacuum chamber 4, thereby creating a negative pressure in the vacuum chamber 4. The smoke and debris generated during the food aurora coding process are sucked into the dust collection box 17 through the air pipe 5.
