For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances. Embodiment 1

[0033] like Figures 1 to 7 As shown in the figure, a laser engraving device includes a cabinet 1, in which a material storage mechanism 21, a material conveying mechanism, a laser engraving machine, a workbench 4 and a control system are arranged, an input device 2 and a material outlet 3 are arranged on the cabinet, the control system is communicatively connected with the material conveying mechanism, the laser engraving machine and the input device, the input device can be a touch screen, the control system is a PLC, and a computer can be installed according to the use requirements;

[0034] The material storage mechanism is provided with a material discharge port, and the material conveying mechanism conveys the engraving material 11 from the material storage mechanism to the engraving area, so as to facilitate the laser engraving machine to perform engraving operations.

[0035] When this embodiment is used, various instructions are input through the input device, such as selecting engraving materials and inputting engraving content, and the instructions are transmitted to the control system. The control system then sends various control instructions to the corresponding material conveying mechanism and the laser engraving machine. The selected engraving material enters the material conveying mechanism from the discharge port of the material storage mechanism. The material conveying mechanism conveys the engraving material to the engraving area. The laser engraving machine engraves the engraving material according to the input engraving content. After engraving, the engraving material is taken out through the material outlet. There is no need to take out the engraving material and then put it into the burning module. It is easy to use.

[0036] In this embodiment, the material conveying mechanism is provided with a first chute 6, the discharge port is located above the first chute and corresponds to the position of the first chute, one end of the first chute is the outlet end, a tray 7 is slidably provided in the first chute, and the tray is connected to a first driving mechanism 8, and the engraving material falls into the first chute from the discharge port of the material storage mechanism. When the first driving mechanism drives the tray to slide along the first chute, it pushes the engraving material in the first chute to slide along the first chute. During this process, the engraving material falls from the discharge port of the material storage mechanism onto the tray. When the tray pushes the engraving material into place, the tray returns. At this time, the engraving material on the tray falls into the first chute. The length of the tray and the pushing distance are reasonably set. During the pushing process of the tray, the engraving material on the tray will not move with the tray. When the engraving material needs to be conveyed, the tray moves forward to push the engraving material.

[0037] Specifically, the first driving mechanism can be a cylinder, an electric push rod, or a motor-driven screw to drive the tray. The thickness of the tray is smaller than the height of the engraving material and also smaller than the distance from the discharge port of the material storage mechanism to the bottom of the first chute, so that the tray only pushes one engraving material at a time.

[0038] A limiting groove 61 is provided on the lower groove wall of the first slide groove. The limiting groove extends along the length direction of the first slide groove. The tray slides in cooperation with the limiting groove, which is conducive to smooth sliding and prevents the tray from falling out of the first slide groove.

[0039] In this embodiment, the outlet end of the first chute is connected to the second chute 9, one end of the second chute is the starting end, and the other end is the outlet end. An engraving area is set at the outlet end of the second chute or at a position on the workbench corresponding to the outlet end of the second chute. The engraving area is an area that facilitates the laser engraving machine to laser engrave the engraving material.

[0040] An accommodating groove 20 is provided near the bottom at one end where the first chute is connected to the second chute, and a groove wall on one side of the second chute is located in the accommodating groove, which is conducive to the engraving material falling smoothly from the first chute into the second chute, avoiding being placed on the groove wall of the second chute and unable to fall smoothly into the second chute.

[0041] In this embodiment, a material drop opening is provided on the workbench below the engraving area, and a material baffle plate 12 is provided at the material drop opening, which is connected to a material drop driving mechanism 13. The material drop opening is communicated with the material outlet, and the material drop driving mechanism can specifically be a cylinder or a motor or other commonly used driving mechanism in this field.

[0042] In this embodiment, the width of the second chute gradually decreases from the starting end to the conveying end, and the groove walls on both sides of the outlet end of the second chute are arranged in parallel.

[0043] In this embodiment, there are more than two first chutes, which are arranged in parallel. Different first chutes can correspond to engraving materials of different specifications. The tray in the first chute pushes the engraving material into the second chute.

[0044] Specifically, the length extension direction of the first chute can be set to be perpendicular to the length extension direction of the second chute. Of course, other angles are also possible, as long as the engraving material can be smoothly transported from the first chute to the second chute. The second chute can receive engraving materials of different specifications. The structural arrangement of the combination of the first chute and the second chute can save space. The engraving material slides from the starting end to the exit end in the second chute until it is aligned with the parallel groove walls on both sides and then enters the engraving area.

[0045] This embodiment further includes a second driving mechanism 16, which is adapted to the second chute and is used to push the engraving material in the second chute to the engraving area;

[0046] Alternatively, the second chute is tilted, the starting end of the second chute is higher than the outlet end, and a suitable tilt angle is set so that the engraving material can slide freely from the starting end of the second chute to the outlet end under its own gravity.

[0047] Specifically, the second driving mechanism can be a cylinder, an electric push rod, or a motor-driven connecting screw structure, which can be arranged behind the second slide groove or below, and can be reasonably arranged according to the space in the cabinet and actual use needs.

[0048] In this embodiment, Figure 8 As shown, the engraving area is provided with a positioning groove 10, and the engraving material enters the positioning groove for positioning. The second driving mechanism forms a contact surface with the engraving material, and the height of the contact surface is less than the depth of the positioning groove. The baffle plate is adapted to the positioning groove. The positioning groove can be set only on the second slide groove, or it can be set on the second slide groove and the workbench.

[0049] During normal use, such as for engraving materials such as commemorative coins, the top of the pushing surface is higher than the top of the commemorative coin. When the commemorative coin falls into the positioning groove, the top of the positioning groove is lower than the pushing surface and will detach from the pushing surface. Even if the second driving mechanism continues to move forward, it will not push the engraving material, thereby avoiding jamming and damaging the engraving material. Embodiment 2

[0050] like Fig. 9 As shown, this embodiment and the first embodiment adopt a basically same structure, the difference being that the second chute is not provided in this embodiment, and an engraving area is provided at the outlet end of the first chute or at a position on the workbench corresponding to the outlet end of the first chute, and a drop opening 23 is provided at the front end of the engraving area on the workbench, and the drop opening is connected to the material outlet. Specifically, a drop chute 14 can be provided between the drop opening and the material outlet, or the positions of the drop opening and the material outlet can be reasonably set, and the engraved material can directly drop to the material outlet position without providing a drop chute.

[0051] This embodiment further simplifies the structure. When in use, the first driving mechanism needs to be controlled to push in sections. After one section of pushing, the engraving material is transported to the engraving area, and the laser engraving machine engraves the engraving material. After the engraving is completed, the first driving mechanism pushes in the second section to push the engraving material after engraving in the engraving area into the drop port.

[0052] The above two embodiments basically illustrate the technical solution of the present utility model. Since the present embodiment is a device with a complex structure, in actual use, more improvements can be made to facilitate installation and use, as follows.

[0053] In this embodiment, more than two fixing holes 17 and more than two adjusting grooves 18 are respectively provided on both sides of the first slide groove. The fixing holes are strip holes, and the length extension direction of the strip holes is perpendicular to the length extension direction of the first slide groove. During the installation process, the position of the first slide groove can be adjusted, and the adjusting groove opens on the side of the first slide groove. In actual use, the adjusting groove is used in conjunction with the adjusting piece. The position of the adjusting groove can be changed by changing the position of the adjusting piece, that is, the position of the first slide groove is adjusted, which can better adapt to the use of engraving materials of different specifications.

[0054] In the first embodiment, the second driving mechanism is provided with a transmission arm 22, the transmission arm is adjustably connected to the second push rod 15, the second push rod 15 is adjustably connected to the push block 19, the push block is used to push the engraving material in the second chute, specifically, a first strip hole extending along the length direction of the second chute can be provided on the push block, the second push rod is provided with a first positioning hole, the first strip hole and the first positioning hole are penetrated by a fastener, and the second push rod and the push block are connected by the fastener;

[0055] A second strip hole is provided at one end of the transmission arm connected to the second push rod, and a second positioning hole is provided on the second push rod. The length extension direction of the second strip hole is perpendicular to the length extension direction of the first strip hole. A fastener is passed through the second strip hole and the second positioning hole, and the second push rod is connected to the transmission arm through the fastener.

[0056] By adjusting the fastening positions of the first strip hole and the first positioning hole, the position of the push block in the length direction of the first slide groove can be adjusted. By adjusting the fastening positions of the second strip hole and the second positioning hole, the position of the push block in the width direction of the second slide groove can be adjusted. The position of the push block can be reasonably adjusted to better suit engraving materials of different specifications.

[0057] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
