[0034] In the application, the driver 8 is a rotary motor, and the second elastic member 52 is a spring.

[0035] Referring to Figure 1 , Figure 2 and Figure 5 , the rear end of the second rotating rod 6 is connected with a second driven bevel gear 62, the second driven bevel gear 62 engages with a third driven bevel gear 71, the left end of the third driven bevel gear 71 is connected with a third rotating rod 7, the third rotating rod 7 can rotate with the third driven bevel gear 71, the left end of the third rotating rod 7 is connected with a driving spur gear 72, the driving spur gear 72 is used in cooperation with a driven spur gear 24 (the driving spur gear 72 and the driven spur gear 24 are located in the same plane), and a chain 73 is arranged between the driving spur gear 72 and the driven spur gear 24, the chain 73 can transmit the rotating force of the driving spur gear 72 to the driven spur gear 24, so that the driving spur gear 72 and the driven spur gear 24 rotate together.

[0036] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 7 , the feeding table 33 is symmetrically provided with a limiting strip 331, and the height of the limiting strip 331 is equal to the height of one machining material 10; the lower end of the feeding table 33 is provided with a pushing block 332; when the feeding table 33 moves backward (i.e. the feeding direction) under the driving of the first threaded rod 34, the one side of the first transmission block 51 and the second transmission block 61 with the insertion slot are clamped to each other, the rotating force of the first threaded rod 34 is transmitted to the third rotating rod 7, the driving spur gear 72 drives the driven spur gear 24 to rotate, and the clamping block 2 slides to the right, so that the machining material 10 between the clamping block 2 and the fixed block 22 is clamped, and the feeding table 33 carrying one machining material 10 moves backward (since the machining material 10 carried by the feeding table 33 is located below the clamping block 2, it will not be affected by the clamping force of the clamping block 2 and the fixed block 22; the limiting strip 331 clamps the machining material 10, so that the machining material 10 moves together with the feeding table 33), with the continuous backward movement of the feeding table 33, the pushing block 332 is separated from the lower part of the transmission clamp 511, the one side of the first transmission block 51 and the second transmission block 61 with the insertion slot are separated from each other, and the clamping block 2 stops moving to the right Figure 7When the feeding table 33 moves forward (the first threaded rod 34 reverses), with the continuous forward movement of the feeding table 33, the pushing block 332 pushes the lower part of the transmission clamp 511 forward, and the first transmission block 51 and the second transmission block 61 are clamped to each other on the side with the insertion slot, so that the rotating force of the first threaded rod 34 is transmitted to the third rotating rod 7, the driving spur gear 72 drives the driven spur gear 24 to rotate, and the clamping block 2 slides to the left, so that the machining material 10 between the clamping block 2 and the fixed block 22 is released. Since the limiting strip 331 will move to the lower part of the machining material 10 between the clamping block 2 and the fixed block 22 in advance, the machining material 10 just released will not fall quickly, and the feeding table 33 continues to move forward until it returns to the initial position (at this time, one machining material 10 falls on the feeding table 33). When the feeding table 33 returns to the initial position, the driver 8 should be reversed (to start the next feeding) or stopped to prevent the clamping block 2 from moving to the left for too long.

[0037] Referring to Figure 1 , Figure 4 and Figure 6 , the limiting piece 12 is arranged on the feeding hole 11, and the limiting piece 12 is an arc-shaped sheet structure. The first elastic piece 121 is arranged between the limiting piece 12 and the feeding hole 11. When the feeding table 33 carrying one machining material 10 enters from the feeding hole 11, the machining material 10 will abut against the arc surface of the limiting piece 12 (the machining material 10 will not be displaced backward due to the support of the limiting strip 331), forcing the limiting piece 12 to press the first elastic piece 121, so that the machining material 10 can smoothly enter the inside of the laser engraving machine body 1 for engraving. When the machining material 10 after engraving moves with the feeding table 33 to the outside of the laser engraving machine body 1, the other side of the limiting piece 12 will abut against the machining material 10 after engraving, forcing the machining material 10 after engraving to fall from the feeding table 33. The machining material 10 after engraving will continue to fall from the opening at the lower part of the laser engraving machine body 1 until it falls into the collection box.

[0038] In the present application, the first elastic piece 121 is a spring.

[0039] Referring to Figure 1 and Figure 2 , the clamping block 2, the fixed block 22, the laser engraving machine body 1 and the lower end of the slide 3 are each provided with a plurality of third support seats 9, which increase the overall height and provide a falling space for the machining material 10 after engraving. The first threaded rod 34, the second rotating rod 6 and the third rotating rod 7 all pass through the second support seat 63, and are all rotationally connected to the second support seat 63. The second support seat 63 is fixedly connected to the third support seat 9 below the clamping block 2, and will not affect the movement of the pushing block 332.

[0040] The device is connected, the feeding table 33 is located at the starting position (the pushing block 332 abuts against the lower part of the transmission clamp 511, the first transmission block 51 and the second transmission block 61 are clamped to each other at the side with the insertion slot), the clamping block 2 and the fixed block 22 are in the released state (i.e. the processing material 10 falls onto the feeding table 33), the driver 8 is started, and the feeding table 33 drives one processing material 10 to move into the laser engraving machine body 1 (due to the distance limitation between the bottom end of the clamping block 2 and the feeding table 33, only one processing material 10 can be driven to move at a time; the remaining processing materials 10 are clamped by the clamping block 2 and the fixed block 22 and cannot fall off), the driver 8 is set, the feeding table 33 moves to the limit distance (at this time, the feeding table 33 abuts against the baffle 32), the driver 8 is stopped, the engraving is completed, the driver 8 is started, the feeding table 33 drives the processing material 10 after engraving to move out of the laser engraving machine body 1, under the action of the limiting piece 12, the processing material 10 after engraving is separated from the feeding table 33, and the feeding table 33 continues to move, the pushing block 332 pushes the lower part of the transmission clamp 511 forward (the length of the pushing block 332 can be set according to the actual situation), the rotating force of the first threaded rod 34 is transmitted to the third rotating rod 7, the clamping block 2 slides to the left, the processing material 10 between the clamping block 2 and the fixed block 22 is released, and when the feeding table 33 returns to the initial position, the feeding is completed once.

[0041] The application provides an automatic feeding laser engraving machine, which realizes automatic feeding and discharging of the laser engraving machine, saves labor, and establishes a connection relationship between the feeding mechanism and the feeding table through the separation effect of the first transmission block and the second transmission block, so that only one driver is needed to realize automatic feeding and discharging multiple times, cost is saved, and processing efficiency is improved.

[0042] Of course, the application can have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the application without departing from the spirit and essence of the application, but these corresponding changes and modifications should belong to the protection scope of the claims attached to the application.
