[0024] Refer to Figures 1-4 For an embodiment of a feeding device of a laser engraving machine of the present utility model,

[0025] This device is an improvement on an integrated laser engraving machine. Before laser engraving an object, it is necessary to place the object into the feeding structure 2 of the laser engraving machine. In order to facilitate engraving, a new feeding structure 2 is provided;

[0026] Among them, the feeding structure 2 includes a support bar 3 and a card slot 4 for setting the support bar 3; the support bar 3 includes a rectangular bar 31 and a triangular bar 32 integrally formed at the upper end of the rectangular bar 31; the cross-section of the triangular bar 32 is an isosceles triangle, and the top side of the triangular bar 32 is arc-shaped.

[0027] A plurality of the card slots 4 of this device are arranged; when in use, the support bar 3 is stuck in the card slot 4, and the number of support bars 3 can be determined according to the size of the item to be engraved. Specifically, which card slot 4 the support bar 3 is stuck in is determined according to needs; after the support bar 3 is installed, the object can be placed on the support bar 3, and then laser engraving can be carried out.

[0028] The structure of the support bar 3 of this device is improved. The support bar 3 includes a rectangular bar 31 and a triangular bar 32 integrally formed at the upper end of the rectangular bar 31; the triangular bar 32 has an inclined surface, so that the debris generated by laser engraving can slide down along the inclined surface of the triangular bar 32 and will not accumulate on the support bar 3; at the same time, in order to facilitate the debris to slide down along the inclined surface of the triangular bar 32, the shape of the triangular bar 32 is specified. The cross-section of the triangular bar 32 is an isosceles triangle, so that a symmetric inclined surface is formed to facilitate the sliding of the debris;

[0029] At the same time, the top edge of the triangular bar 32, that is, the edge in contact with the material, is set to be arc-shaped, which is convenient for placing the material on the one hand and also convenient for the debris to slide down on the other hand.

[0030] The card slot 4 is arranged on the upper mounting plate 5 located in the engraving machine body 1; a rectangular through groove 6 is arranged in the middle of the upper mounting plate 5. Vertical plates 7 are arranged on the two long sides of the rectangular through groove 6. A first gap 41 is arranged between the vertical plates 7, and a second gap 42 is arranged on the upper mounting plate 5. The first gap 41 and the second gap 42 form the card slot 4, and the card slot 4 communicates with the rectangular through groove 6.

[0031] The structure of the upper mounting plate 5 of this device is designed according to the integrated laser engraving machine. A rectangular through groove 6 is arranged in the center. This rectangular through groove is the placement space provided for the material when engraving the material, and the debris generated by engraving will also directly fall through the through groove 6;

[0032] The function of the vertical plate 7 is to set the first gap 41 and at the same time lengthen the length of the gap to match the thickness of the rectangular bar 31 of the support bar 3. The setting of the second gap 42 can facilitate the insertion of the support bar 3. Therefore, the entire card slot 4 is jointly formed by the first gap 41 and the second gap 42.

[0033] A support plate 8 is also arranged at the lower end of the upper mounting plate 5. The support plate 8 is located directly below the card slot 4; the support plate 8 is horizontally arranged as a whole, and a connecting plate 9 is arranged at the upper end of the support plate 8, and a horizontal plate 10 is arranged at the upper end of the connecting plate 9.

[0034] The function of the support plate 8 in this device is that after the support bar 3 is inserted into the card slot 4, the support bar 3 can be supported by the support plate 8; a connecting plate 9 is arranged at the upper end of the support plate 8 of this device. The main function of the connecting plate 9 is to raise the height of the horizontal plate 10, facilitate the contact between the horizontal plate 10 and the lower end surface of the upper mounting plate 5, and at the same time fix the horizontal plate 10 on the upper mounting plate 5 with screws.

[0035] A chute plate 11 is also arranged at the lower end of the upper mounting plate 5. The chute plate 11 includes a bottom plate 12. A limiting plate 13 is arranged at the upper end of the bottom plate 12. A top plate 14 is arranged at the upper end of the limiting plate 13. A chute is arranged between the top plate 14 and the bottom plate 12, and a material receiving plate 15 is slidably arranged in the chute.

[0036] A receiving plate 15 is provided below the support bar 3 of this device. The main function of this receiving plate 15 is to collect the debris generated by engraving. When the debris in the receiving plate 15 accumulates to the full, it is necessary to clean the debris in the receiving plate 15. Therefore, in order to facilitate the cleaning of the debris in the receiving plate 15, it is set as a sliding structure similar to a drawer. Specifically, the chute plate 11 includes a bottom plate 12. A limiting plate 13 is provided at the upper end of the bottom plate 12, and a top plate 14 is provided at the upper end of the limiting plate 13. The chute is arranged between the top plate 14 and the bottom plate 12, and the receiving plate 15 is slidably arranged in this chute.

[0037] A cushioning platform 16 is also provided at the lower end of the laser engraving machine body 1. The space inside the cushioning platform 16 is separated from the space inside the laser engraving machine body 1 by the receiving plate 15.

[0038] In this device, through the design of the cushioning platform 16, laser engraving can be carried out on large items. When in use, it is necessary to remove the support bar 3 and at the same time place the receiving plate 15 in the cushioning platform 16. At this time, the receiving plate 15 is equivalent to the original support bar 3. However, the difference is that the thickness of the object is different. For thinner objects, it is penetrative engraving, and for thicker objects, it is surface engraving. Therefore, there is no need to use the support bar 3.

[0039] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this utility model creation.
