[0029] Reference Figure 1-7This utility model embodiment discloses a laser engraving equipment for a TV back cover production line, comprising a laser engraving machine 1.

A support plate 2 is fixedly connected to the left surface of the laser engraving machine 1. A support block 3 is fixedly connected to the upper surface of the support plate 2.

A connecting shaft 11 is fixedly connected to the inner surface of each connecting block 10. A common connecting rod 12 is rotatably connected to both connecting shafts 11. A protective plate 13 is fixedly connected to the side surface of the connecting rod 12. A bearing ring 14 is movably connected to the inner surface of the bearing ring 14. A connecting ring 15 is movably connected to the inner surface of the bearing ring 14. An air filter screen 16 is fixedly connected to the lower surface of the connecting ring 15. Activated carbon adsorption cotton 17 is movably connected to the inner surface of the filter box 7. A recess 18 is fixedly connected to the inner surface of the filter box 7. A first sealing strip 19 is fixedly connected to the inner surface of the protective plate 13. A second sealing strip 20 is provided. The right surface of the protective plate 13 contacts the filter box 7, the bearing ring 14, the activated carbon adsorption cotton 17, and the recess 18. The right surface of the first sealing strip 19 contacts the second sealing strip 20. A pull block 33 is fixedly connected to the left surface of the protective plate 13. The pull block 33 provides a point of force for the protective plate 13, facilitating its opening. The lower surface of the recess 18 contacts the activated carbon adsorption cotton 17, and the upper surface of the recess 18 contacts the air filter 16. The air filter 16 is made of stainless steel. It should be noted that the air filter 16 is made of a rigid material. When the protective plate 13... After closing, the protective plate 13 and the filter box 7 prevent the structure such as the bearing ring 14, connecting ring 15 and air filter 16 from moving freely inside the filter box 7. The right surface of the filter box 7 is fixedly connected to the connecting plate 29, and the right surface of the connecting plate 29 is fixedly connected to the laser engraving machine 1. There are two connecting plates 29 and they are symmetrically distributed.

The bearing ring 14 has a positioning groove 30, and the outer surface of the connecting ring 15 is movably connected to the positioning groove 30.

Movable plates 26 are fixedly connected to the front surfaces of both the first slider 23 and the second slider 24.

The outer surface of the insert block 27 is movably connected to the limiting groove 32. By setting the sliding groove 31, the first slider 23, the second slider 24 and other structures can move smoothly, while also restricting the movement direction of the first slider 23 and the second slider 24, so that they can only move in the parallel direction.

[0031] Working Principle: When using the laser engraving machine 1 to process the back cover of a TV, the fan 4 on the support block 3 is activated, causing the connecting pipe 6 at the input end of the fan 4 to generate suction. As the fan 4 continuously generates suction, a negative pressure is created inside the filter box 7. Simultaneously, a negative pressure is created between the air inlet pipe 8 and the air inlet head 9, drawing air from around the air inlet head 9 into the filter box 7. This process draws in odorous gases and dust particles generated during the processing of the TV back cover. When the gas needs to enter the fan 4 and be discharged to the outside environment through the exhaust pipe 5 at the output end of the fan 4, it first comes into contact with the air filter 16 on the connecting ring 15. Under the action of the air filter 16, the dust particles in the gas are filtered out. Dust particles and impurities are filtered, and the gas filtered by the air filter 16 continues to come into contact with the activated carbon adsorption cotton 17 during its circulation. Because the activated carbon adsorption cotton 17 has a good adsorption effect, it can adsorb and treat the initially filtered gas, absorbing organic matter and odors. The treated gas then enters the fan 4 through the connecting pipe 6, and finally is discharged back into the external environment through the exhaust pipe 5 at the output end of the fan 4, thus achieving air circulation and the treatment of dust particles and odors. By squeezing the two movable plates 26 to the same side, the two moving movable plates 26 can respectively drive the first slider 23 and the second slider 24 to move closer to each other, and at the same time... As the movable insert 27 moves, the first slider 23 and the second slider 24 gradually compress the spring 25 as they move on the guide rod 22, thus keeping the spring 25 taut. When the movable insert 27 disengages from the limiting groove 32, the fixation on the protective plate 13 and its structure is released. Then, by pulling the pull block 33, the protective plate 13 and its structure can be rotated around the connecting shaft 11 on the connecting block 10, thereby opening the protective plate 13. Once the protective plate 13 is open, the restrictions on the bearing ring 14, activated carbon adsorption cotton 17, and other structures on the bearing ring 14 are released. At this point, the bearing ring 14 and activated carbon adsorption cotton 17 can be pulled out of the filter box 7. After the carrier ring 14 is removed from the filter box 7, the connecting ring 15 can be removed from the positioning groove 30 on the carrier ring 14. Once the carrier ring 14, activated carbon adsorption cotton 17, and other structures are removed, the air filter 16 can be cleaned and maintained to avoid obstructing airflow. The activated carbon adsorption cotton 17 can also be replaced to maintain its adsorption effect and prevent obstruction of airflow. Then, the squeezed movable plate 26 is released, and the spring 25 rebounds, allowing it to move the first slider 23, the second slider 24, the movable plate 26, and the insert block 27 back to their original positions. After the air filter 16 is cleaned, the connecting ring 15 is placed back into the positioning groove 30 on the carrier ring 14.Then, place the carrier ring 14 into the filter box 7, so that the upper surface of the connecting ring 15 contacts the inner top wall of the filter box 7, and the lower surface of the air filter 16 contacts the recess 18, thus achieving initial installation between the air filter 16 and the carrier ring 14. Simultaneously, place a new, identical type of activated carbon absorbent cotton 17 into the space between the recess 18 and the filter box 7, such as... Figure 7 As shown, press the two movable plates 26 again, causing the movable plates 26 to move the first slider 23 and the second slider 24 closer to each other, while keeping the spring 25 taut. When the movable plates 26 and the insert block 27 no longer affect the flipping of the protective plate 13, flip the protective plate 13 in the opposite direction, so that the protective plate 13 and the structure on the protective plate 13 flip in the opposite direction with the connecting shaft 11 as the central axis. When the flipped protective plate 13 comes into contact with the filter box 7, the bearing ring 14, the activated carbon adsorption cotton 17, the concave block 18, and the first sealing strip 19 and the second sealing strip 20, the limiting groove on the limiting block 28 after flipping can also be made to... Corresponding to the insert 27, the movable plate 26 is released, allowing the spring 25 to rebound without restriction. The rebounding spring 25 drives the first slider 23, the second slider 24, the movable plate 26, and the insert 27 to move back to their original positions. When the two moving inserts 27 are inserted into the two limiting slots 32 respectively, the protective plate 13 and other structures on the protective plate 13 can be fixed, preventing them from moving and completing the closure of the protective plate 13. Furthermore, under the contact of the first sealing strip 19 and the second sealing strip 20, the sealing effect between the protective plate 13 and the filter box 7 can be improved, ensuring that the gas flows along the designed path and that the gas can be transported stably.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
