[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: an automatic loading mechanism of a laser marking machine, including:

[0026] A loading conveyor table 1, and an automatic loading table 2 is fixedly connected to one side of the loading conveyor table 1;

[0027] A limiting structure, and the limiting structure is located on the loading conveyor table 1;

[0028] The limiting structure includes a transmission box 16, a gear 14, a rotating motor 15, a first rack 8, two connecting frames 9 and a second rack 13. The transmission box 16 is fixedly connected to the bottom of the feeding conveyor table 1. The rotating motor 15 is fixedly installed inside the transmission box 16. The output end of the rotating motor 15 is fixedly connected to the gear 14. The two connecting frames 9 are respectively slidably connected to both sides of the feeding conveyor table 1. The bottom ends of the two connecting frames 9 are respectively fixedly connected to the first rack 8 and the second rack 13. The first rack 8 and the second rack 13 both slidably extend into the transmission box 16. The first rack 8 and the second rack 13 are both meshed with the gear 14.

[0029] The opposite ends of the two connecting frames 9 both slidably extend into the feeding conveyor table 1 and are fixedly connected with limiting frames 10. A plurality of limiting columns 11 are rotatably connected inside the two limiting frames 10. A guiding arc plate 17 is fixedly connected to one side of each of the two limiting frames 10. A sliding groove 4 is formed in the inner bottom wall of the automatic feeding table 2. A pushing plate 6 is slidably connected to the inner bottom wall of the automatic feeding table 2. The bottom end of the pushing plate 6 is slidably connected inside the sliding groove 4.

[0030] An eccentric disk 7 is rotatably connected inside the automatic feeding table 2. A connecting rod 5 is rotatably connected to the top of the eccentric disk 7. One end of the connecting rod 5 far from the eccentric disk 7 is rotatably connected to the pushing plate 6. A driving motor 12 is fixedly installed at the bottom of the automatic feeding table 2. The output end of the driving motor 12 rotatably penetrates through the bottom of the automatic feeding table 2 and is fixedly connected to the eccentric disk 7. Two storage racks 3 are fixedly connected inside the automatic feeding table 2.

[0031] Further, when using this device, by connecting to an external power source to start the driving motor 12, the driving motor 12 will drive the eccentric disk 7 to rotate. The rotation of the eccentric disk 7 will drive the connecting rod 5 to move and rotate simultaneously. The movement of the connecting rod 5 will drive the pushing plate 6 to move under the guidance of the sliding groove 4, so as to facilitate pushing out the lowest sheet material stacked in the two storage racks 3. Under the rotation of the eccentric disk 7, the connecting rod 5 can reciprocally push out the sheet material. Subsequently, the feeding conveyor table 1 will convey the pushed-out sheet material. By connecting to an external power source to start the rotating motor 15, the rotating motor 15 will drive the gear 14 to rotate. The rotation of the gear 14 will drive the first rack 8 and the second rack 13 to move in opposite directions. The movement of the first rack 8 and the second rack 13 will drive the corresponding connecting frames 9 to move. Thus, the two connecting frames 9 will drive the two limiting frames 10 to approach each other, so as to facilitate the contact of the multiple limiting columns 11 on the two limiting frames 10 with both sides of the sheet material, enabling the two guiding arc plates 17 to guide the conveyance of the sheet material, and further facilitating the alignment of the sheet material by the multiple limiting columns 11, without the need for staff to organize and place it.

[0032] With the cooperation of the limit frame 10, the limit posts 11, the connecting frame 9, the first rack 8, the second rack 13, the gear 14 and the guiding arc plate 17, the two connecting frames 9 will drive the two limit frames 10 to approach each other, so that it is convenient for the multiple limit posts 11 on the two limit frames 10 to contact both sides of the sheet material, thus facilitating the alignment of the sheet material by the multiple limit posts 11, avoiding the situation that the sheet material is prone to deviation when entering the loading conveyor table 1, and eliminating the need for workers to adjust the placement, further improving the marking efficiency of the sheet material.

[0033] Working principle: Start the drive motor 12 by connecting to an external power source. The drive motor 12 will drive the eccentric disc 7 to rotate. The rotation of the eccentric disc 7 will drive the connecting rod 5 to move and rotate simultaneously. The movement of the connecting rod 5 will drive the push plate 6 to move under the guidance of the sliding groove 4, so as to facilitate the pushing out of the lowermost sheet material stacked in the two storage racks 3. Under the rotation of the eccentric disc 7, the connecting rod 5 can reciprocally push out the sheet material. Subsequently, the loading conveyor table 1 will convey the pushed-out sheet material. Start the rotation motor 15 by connecting to an external power source. The rotation motor 15 will drive the gear 14 to rotate. The rotation of the gear 14 will drive the first rack 8 and the second rack 13 to move in opposite directions. The movement of the first rack 8 and the second rack 13 will drive the corresponding connecting frames 9 to move. Thus, the two connecting frames 9 will drive the corresponding limit frames 10 to approach each other, so that it is convenient for the multiple limit posts 11 on the two limit frames 10 to contact both sides of the sheet material, enabling the two guiding arc plates 17 to guide the conveyance of the sheet material, and further facilitating the alignment of the sheet material by the multiple limit posts 11 without the need for workers to arrange and place it.

[0034] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
