Description

Technical Field

[0001] This utility model relates to the technical field of laser marking machines, specifically a laser marking machine for preventing smoke interference. Background Technology

[0002] The CO2 laser marking machine uses an imported encapsulated CO2 laser, equipped with a German high-speed scanning galvanometer and beam expanding and focusing system, resulting in high marking accuracy and speed. The ZJ-2626A laser has an adjustable height for easy use and can be fitted with lenses of various marking widths. It has a long continuous working time, produces clear and beautiful marks, and features powerful software functions, including serial number marking and on-the-fly marking. The fixed laser marking design is simple to operate, and the complete upper and lower ventilation system ensures environmentally friendly and safe operation. It is suitable for various leathers, two-color boards, plastics, and various solid materials.

[0003] Existing carbon dioxide laser marking machines, such as the one mentioned above, use carbon dioxide gas to generate glow discharge in a high-voltage discharge tube, causing gas molecules to release laser light. After amplifying the laser energy, a laser beam is formed to process the material. The laser beam vaporizes the surface of the workpiece to achieve the purpose of engraving. Under high-heat processing conditions, the material surface will react rapidly, producing a large amount of toxic gases and particles.

[0004] The existing technical solutions mentioned above have the following drawbacks: the smoke effect of the mixed gas during the marking process has a high loss rate of laser energy, which affects the marking quality. Therefore, a device is needed that can remove smoke in a timely manner during the marking process to ensure the marking quality. Utility Model Content

[0005] The purpose of this invention is to provide a laser marking machine that is resistant to smoke interference.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The system includes a workbench body. A lifting column controlled by a rotary wheel and a marking control computer are fixedly installed on the outer wall of the workbench body. A laser marking machine body is mounted on the lifting column, which slides up and down. A marking lens is fixedly installed at the end of the laser marking machine body. A positioning plate that mates with the marking lens is fixedly installed on the top wall of the workbench body. A dust cover is provided around the marking lens, covering the positioning plate. An air inlet and an air outlet are provided on both sides of the dust cover in the horizontal direction. An intake fan and an exhaust fan are respectively installed at the air inlet and outlet. A movable groove for the laser marking machine body to move up and down is provided near the dust cover. An upper baffle and a lower baffle that cover the movable groove are extended from the top and bottom walls of the laser marking machine body. A workpiece loading / unloading opening is provided on one side of the outer wall of the dust cover. A magnetic cover that hinges to the outer wall of the dust cover covers the workpiece loading / unloading opening.

[0007] By adopting the above technical solution, during use, first rotate the rotary wheel to move the marking machine body to a suitable height, then open the magnetic cover, place the workpiece to be marked on the positioning plate, start the inlet and outlet fans to form a stable air duct, and start the marking machine body to mark. The movable slot allows for free adjustment of the height of the marking machine body. The upper and lower baffles are longer than the movable slot, so the movable slot is always well sealed during the movement. When the magnetic cover is closed, the dust cover is well sealed by magnetic attraction. The stable air duct formed by the inlet and outlet fans blows on the surface of the workpiece for a long time. When smoke particles are generated during the marking process, they can be removed and carried away in time, effectively avoiding the obstruction and loss of the laser by smoke particles, and effectively ensuring the overall quality of marking.

[0008] Furthermore, the top wall of the workbench body is provided with an insertion slot for the lower baffle to be inserted.

[0009] By adopting the above technical solution, during the downward movement of the laser marking machine body, the lower baffle will abut against the worktable body, affecting the lifting and lowering of the laser marking machine. Therefore, the setting of the insertion slot allows the lower baffle to be inserted into the worktable without obstruction during the descent, ensuring that the marking machine body rises and falls smoothly.

[0010] Furthermore, the outer wall of the dust cover extends to provide an installation cylinder surrounding the air inlet, the installation cylinder is filled with an air filter element, the installation cylinder is threadedly connected to an outer cylinder with a pressed air filter element, and a first dustproof net is fixedly installed at the middle of one end of the outer cylinder that is in contact with the air filter element.

[0011] By adopting the above technical solution, the air filter element, together with the first dustproof net of the outer cylinder, performs double filtration of the air inlet, effectively filtering out particulate impurities in the air, effectively improving the air cleanliness of the marking operation room, and further ensuring the marking effect.

[0012] Furthermore, the air outlet is covered with a second dustproof net, the dustproof cover is fixedly provided with a connecting cylinder surrounding the air outlet, and the inner wall of the dustproof cover is fixedly provided with a protective net covering the air inlet and the air outlet.

[0013] By adopting the above technical solution, the second dustproof net further seals the air outlet, thereby effectively protecting the dustproof cover from dust in all directions, preventing external dust and impurities from entering the marking operation room and affecting the marking quality. At the same time, it can stably remove impurities and particles, resulting in good marking quality. The connecting cylinder is designed to facilitate later connection to the exhaust gas treatment system, making it convenient for centralized treatment of exhaust gas and providing higher adaptability. The protective net can effectively protect hands and prevent cuts.

[0014] In summary, the beneficial technical effects of this utility model are as follows: 1. It adopts a dustproof cover, air inlet, air outlet, air inlet fan and air outlet fan to form a stable air channel to blow on the workpiece surface for a long time. When smoke particles are generated during the marking process, they can be removed and carried away in time, effectively avoiding the obstruction and loss of laser by smoke particles, and effectively ensuring the overall quality of marking. 2. The design incorporates a movable groove, a slide groove, an upper baffle, and a lower baffle, ensuring smooth ascent and descent of the marking machine body while effectively sealing the dust cover to prevent the intrusion of external dust, impurities, and particles.

[0015] 3. It adopts an air filter, a first dust filter, and a second dust filter to ensure that the airflow in the duct remains clean at all times, while stably removing impurities and particles, thus improving the marking quality. Attached Figure Description

[0020] Please see Figure 1-3 The present invention provides the following technical solution: The workbench body 1 includes a lifting column 2 controlled by a rotary wheel and a marking control computer 3 fixedly installed on the outer wall of the workbench body 1. The lifting column 2 slides up and down to install the laser marking machine body 4. The laser marking machine body 4 is fixedly installed at the end of the laser marking machine body 4. The top wall of the workbench body 1 is fixedly installed with a positioning plate 5 that matches the marking lens 41. The marking lens 41 is covered by a dust cover 6, which covers the positioning plate 5. The dust cover 6 has an air inlet 61 and an air outlet 62 on both sides along the horizontal direction. The air inlet 61 and the air outlet 62 are respectively equipped with an air intake fan 611 and an air outlet fan 621. The dust cover 6 has a movable groove 7 near the laser marking machine body 4 for the laser marking machine body to move up and down. The top and bottom walls of the laser marking machine body 4 have an upper baffle 71 and a lower baffle 72 that cover the movable groove 7. The outer wall of one side of the dust cover 6 has a workpiece loading and unloading area. The dust cover 6 has a magnetic cover 81 hinged to its outer wall to cover the workpiece loading and unloading opening 8. In use, first rotate the rotary wheel to move the marking machine body to a suitable height, then open the magnetic cover 81, place the workpiece to be marked on the positioning plate 5, start the inlet fan 611 and outlet fan 621 to form a stable airflow, and start the marking machine body for marking. The movable slot 7 allows for free adjustment of the marking machine body height. The upper baffle 71 and lower baffle 72 are longer than the movable slot 7, thus maintaining a good seal on the movable slot 7 during movement. When the magnetic cover 81 is closed, it effectively seals the dust cover 6 through magnetic attraction. The stable airflow formed by the inlet fan 611 and outlet fan 621 blows on the workpiece surface for a long time. When smoke particles are generated during marking, they are promptly removed and carried away, effectively preventing smoke particles from obstructing and damaging the laser, and effectively ensuring the overall quality of marking.

[0021] The top wall of the worktable body 1 is provided with an insertion slot 73 for the lower baffle 72 to be inserted.

The mounting cylinder 9 is threadedly connected to an outer cylinder that presses against the air filter element 91. A first dustproof net 92 is fixedly installed at the middle of one end of the outer cylinder that is in contact with the air filter element 91. The air filter element 91, together with the first dustproof net 92 of the outer cylinder, performs double filtration of the air inlet 61, effectively filtering out particulate impurities in the air, effectively improving the air cleanliness of the marking operation room, and further ensuring the marking effect.

[0023] The air outlet 62 is covered with a second dustproof net 93, and the dustproof cover 6 is fixedly provided with a connecting cylinder 94 surrounding the air outlet 62. The second dustproof net 93 further seals the air outlet 62, thereby effectively protecting the dustproof cover 6 from dust in all directions, preventing external dust and impurities from entering the marking operation room and affecting the marking quality. At the same time, it can stably remove impurities and particles, resulting in good marking quality. The connecting cylinder 94 is designed to facilitate later connection to the exhaust gas treatment system, making it convenient for centralized treatment of exhaust gas and improving adaptability. The inner wall of the dustproof cover 6 is fixedly provided with a protective net 10 covering the air inlet 61 and the air outlet 62 to prevent hand cuts.
