For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0027] Reference Figures 1 to 9 In an embodiment of the present invention, a laser cutting device for making special-shaped advertisements includes: a device body 1 and a stepper motor 3, a laser cutting mechanism 2 for cutting acrylic plates is arranged at one end above the device body 1, a pushing component 5 for pushing the acrylic plates for loading is arranged at one end inside the device body 1, a pushing mechanism 4 for driving the pushing component 5 to move back and forth is arranged at one end on the side of the stepper motor 3, and a lifting mechanism 6 for lifting the stacked acrylic plates is arranged at one end on the side of the device body 1.

[0028] The pushing assembly 5 includes a moving block 51 arranged at one end inside the device body 1, a pushing block assembly 52 for pushing the bottom acrylic plate is arranged at the upper end of the moving block 51, a slider 53 is fixedly connected to one end of the side of the moving block 51, a third rack 54 is fixedly connected to one end of the lower end of the moving block 51, a fixed bar 55 is fixedly connected to one end of the side of the moving block 51, and a fourth rack 56 is fixedly connected to one end of the side of the fixed bar 55.

[0029] The pushing block assembly 52 includes a pushing block body 521 fixedly connected to one end above the moving block 51 . A groove 522 is provided at one end above the pushing block body 521 .

[0030] By adopting the above solution, when the pushing component 5 moves backward, the pushing bevel block 524 will contact the acrylic plate stacked above. Under the action of the acrylic plate stacked above, the pushing bevel block 524 squeezes the inclined surface, so that the pushing bevel block 524 retracts into the groove 522, thereby preventing the pushing bevel block 524 from hooking on the acrylic plate stacked above and getting stuck when moving backward.

[0031] The pushing mechanism 4 includes a connecting rod 41 arranged at one end of the side of the stepping motor 3, one end of the side of the connecting rod 41 is fixedly connected to a first rotating arm 42, one end of the side of the first rotating arm 42 is rotatably connected to a second rotating arm 43, one end of the side of the second rotating arm 43 is rotatably connected to a third gear 44, and one end of the side of the third gear 44 is provided with a second rack 45.

[0032] The lifting mechanism 6 includes a fixing seat 61 disposed at one end of the side of the device body 1 , a moving component 62 is disposed at one end of the side of the fixing seat 61 , and a lifting component 63 is disposed at one end of the side of the fixing seat 61 .

[0034] With the above solution, the lifting bevel block 635 is a triangular bevel block, which can not only be inserted between the acrylic plates more easily, but also separate the acrylic plates as it is gradually inserted, and the bevel surface can drive the lifting bevel block 635 to reset under the gravity of the acrylic plates.

[0035] The device body 1 includes a support base 11 arranged at one end of the side of the stepping motor 3, a circular groove 12 adapted to the laser cutting mechanism 2 is opened at the upper end of the support base 11, four groups of limit blocks 13 for limiting the acrylic plate are fixedly connected to the upper end of the support base 11, a workbench 14 for cutting the acrylic plate is arranged at the upper end of the support base 11, a through groove 15 adapted to the lifting mechanism 6 is opened at one end of the side of the support base 11, a slide groove 16 adapted to the pushing component 5 is opened at one end of the side of the support base 11, a fixing plate 17 supporting the pushing mechanism 4 is fixedly connected to one end of the side of the support base 11, a rotating rod 18 is rotatably connected to one end of the side of the support base 11, a first gear 19 adapted to the laser cutting mechanism 2 is fixedly connected to one end of the side of the rotating rod 18, and a second gear 110 adapted to the pushing component 5 is fixedly connected to one end of the side of the rotating rod 18.

[0036] The laser cutting mechanism 2 includes a telescopic rod 24 arranged at one end above the device body 1, a connecting seat 22 is fixedly connected to the upper end of the telescopic rod 24, a first spring 25 is arranged between the telescopic rod 24 and the connecting seat 22 for returning the connecting seat 22 after rising, a first rack 23 is fixedly connected to one end of the side of the connecting seat 22, and a laser cutter 21 is arranged at one end above the connecting seat 22.

[0037] With the above solution, the first spring 25 can make the connection seat 22 descend more quickly and ensure that the connection seat 22 fits the upper part of the device body 1, so that the connection seat 22 can be in the working position to cut the acrylic plate more stably.

[0038] The working principle of the present invention is as follows: first, the connecting rod 41 is driven to rotate by the stepping motor 3, thereby driving the first rotating arm 42 fixed to the side to rotate, and the second rotating arm 43 and the third gear 44 connected to the side rotation are driven to reciprocate and rotate under the action of the second rack 45 by the first rotating arm 42, and the third gear 44 is driven to rotate and move above the second rack 45, thereby driving the third rack 54 meshing above to move, thereby driving the entire pushing assembly 5 to slide in the slide groove 16, and by stacking the acrylic plates to be cut and placing them in the middle of the four groups of limit blocks 13, when the pushing assembly 5 slides, the moving block 51 will squeeze the triangular inclined block 623 connected to the side sliding, so that it slides outward, and when the first gear plate 6 slides 22 will drive the fourth gear 612 meshed on the side to rotate, thereby driving the lifting component 63 on the other side to move toward the stacked acrylic plates, and the lifting inclined block 635 is just inserted between the second acrylic plate from the bottom and the lowest acrylic plate. As the lifting inclined block 635 is gradually inserted, the two acrylic plates are separated, leaving a gap in the middle. Then, when the pushing block component 52 is pushed toward the acrylic plate, the pushing inclined block 524 will push the bottom acrylic plate and push it onto the workbench 14. The gap in the middle can reduce the contact area between the acrylic plates, thereby reducing the friction force, avoiding the acrylic plate surface being damaged by friction when the acrylic plate is pushed due to excessive accumulation. When the pushing component 5 pushes the bottom acrylic plate In the process of pushing the acrylic plate onto the workbench 14, the fourth rack 56 on the side will first mesh with the second gear 110, and the second gear 110 will be driven to rotate during the pushing process, thereby driving the rotating rod 18 and the first gear 19 to rotate. When the first gear 19 rotates, it will drive the entire laser cutting mechanism 2 to rise through the first rack 23 meshing on the side, thereby avoiding the laser cutting machine 21 blocking the acrylic plate from entering the workbench 14 when pushing the material. After the pushing is completed, the third gear 44 will move backward and rotate under the action of the first rotating arm 42, the second rotating arm 43 and the second rack 45, thereby driving the pushing component 5 to slide backward. When the pushing component 5 moves backward, it will drive the second gear 11 through the fourth rack 56 0 rotates in the opposite direction, thereby driving the laser cutting mechanism 2 to descend to the working position, so as to cut the acrylic plate. When the pushing component 5 moves backward, the pushing inclined block 524 will contact the acrylic plate stacked above. The pushing inclined block 524 squeezes the inclined surface under the action of the acrylic plate stacked above, so that the pushing inclined block 524 is retracted into the groove 522, so as to avoid the pushing inclined block 524 being hooked on the acrylic plate stacked above and getting stuck when moving backward. When the pushing component 5 moves backward to the rearmost position, the stacked acrylic plate will press the lifting inclined block 635 downward by gravity to make it move sideways. When the lifting component 63 moves sideways, the side moving component 62 is driven to reset by the fourth gear 612, which can make the feeding more continuous.

[0039] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
