Embodiment

[0030] Please refer to Figs. 1-6As shown, the laser marking machine with the dustproof structure of the embodiment is provided with the filter screen 6 on the side of the mounting back plate 4 close to the mounting groove 3, and the filter screen 6 is detachably connected with the side wall of the mounting back plate 4. Specifically, the detachable filter screen 6 is arranged on the side of the mounting back plate 4 close to the mounting groove 3, thereby providing an additional dustproof layer for the laser marking machine. The filter screen 6 can further block dust particles in the air, and together with the filter plate 14, forms a double dustproof guarantee. When the laser marking machine works, the external air is firstly subjected to preliminary filtration through the filter plate 14, and then subjected to secondary filtration through the filter screen 6, and finally enters the inside of the laser marking machine. When the filter screen 6 accumulates a large amount of dust, the user can conveniently detach it for cleaning or replacement. The dustproof performance of the laser marking machine is improved, the clean environment inside the equipment is ensured, and the service life of the equipment is prolonged.

[0031] The mounting back plate 4 is fixedly connected with the hooks 7 at four corners of one side, and the four corners of the filter screen 6 are detachably connected with the hooks 7. Specifically, the hooks 7 on the mounting back plate 4 and the corners of the filter screen 6 are detachably connected, thereby realizing quick installation and detachment of the filter screen 6. The hook connection structure is not only convenient to install, but also can ensure the stability of the filter screen 6 during installation. When installing the filter screen 6, the user only needs to hang the four corners of the filter screen 6 on the hooks 7 on the mounting back plate 4. When the filter screen 6 needs to be detached for cleaning or replacement, the user only needs to take it off from the hooks 7. The installation and detachment process of the filter screen 6 is simplified, the maintenance efficiency is improved, and the stability of the filter screen 6 is ensured.

[0032] The filter hole diameter of the filter screen 6 is smaller than that of the filter plate 14, and the mounting back plate 4 is connected with the inside of the mounting groove 3 through a plurality of bolt rods. Specifically, the filter hole diameter of the filter screen 6 is designed to be smaller than that of the filter plate 14, thereby realizing the hierarchical filtration of dust particles in the air. Larger dust particles are firstly blocked by the filter plate 14, and smaller dust particles are further filtered by the filter screen 6 after passing through the filter plate 14. At the same time, the mounting back plate 4 is stably connected with the mounting groove 3 through the bolt rods, thereby ensuring the reliability of the entire ventilation and dustproof assembly. When the laser marking machine works, the external air is firstly subjected to preliminary filtration through the filter plate 14 to block larger dust particles. Then, the air subjected to preliminary filtration is subjected to secondary filtration through the filter screen 6 to block smaller dust particles. Finally, the clean air enters the inside of the laser marking machine for heat dissipation. The dustproof effect of the laser marking machine is improved, the cleanliness of the air entering the inside of the equipment is ensured through hierarchical filtration, and the stability of the ventilation and dustproof assembly is enhanced.

[0033] The scheme has the following working process:

[0034] Heat dissipation and ventilation: The laser marking machine 1 will generate a large amount of heat during normal operation. In order to effectively dissipate this heat, the installation slot 3 opened on the back serves as a heat dissipation channel, which is in communication with the inside of the laser marking machine 1. The ventilation and dust prevention assembly 2 is installed in the installation slot 3, and is fixed by the detachable connection of the installation back plate 4 with the installation slot 3. The installation back plate 4 is provided with a plurality of air inlets 8, allowing external cold air to enter the inside of the laser marking machine, promoting air convection, thereby taking away the internal heat.

[0035] Dust prevention mechanism: In order to prevent dust from entering the inside of the laser marking machine through the air inlets 8, an arc-shaped ventilation box 5 is arranged on one side of each air inlet 8. The side of the arc-shaped ventilation box 5 close to the air inlet 8 is provided with a through slot 11, allowing air to flow smoothly. The filter plate 14 is connected in the air inlet slot 13 on one side of the bottom of the arc-shaped ventilation box 5, which can effectively block dust particles in the air. With the continuous operation of the laser marking machine 1, the internal heat is continuously discharged through the installation slot 3 and the air inlet 8, while the filter plate 14 continuously intercepts dust, maintaining a clean environment inside the equipment.

[0036] Maintenance convenience: When the dust on the filter plate 14 accumulates to a certain extent, the user can conveniently detach the installation back plate 4. Specifically, by loosening the bolts connecting the side plate and the side slot, the user can easily take out the filter plate 14 for cleaning or replacement. After completion, the new or cleaned filter plate 14 is re-fixed in the arc-shaped ventilation box 5 by the bolt connection of the side plate and the side slot. In addition, the side of the installation back plate 4 close to the installation slot 3 is also provided with a detachable filter screen 6, which further blocks dust particles in the air. The four corners of the filter screen 6 are connected with the hooks 7 on the installation back plate 4, facilitating the user to quickly install and detach the filter screen 6 for cleaning or replacement.

[0037] Classification filtering: In order to improve the dust prevention effect, the filter hole diameter of the filter screen 6 is designed to be smaller than that of the filter plate 14, realizing the classification filtering of dust particles in the air. The external air is first subjected to primary filtering by the filter plate 14, blocking larger dust particles; then, the air subjected to primary filtering is subjected to secondary filtering by the filter screen 6, blocking smaller dust particles. Finally, the clean air enters the inside of the laser marking machine for heat dissipation.
