After the marking rod 508 rotates away from the steel bar, the elastic force of the first spring 511 pushes the fixed plate 510, at this time, the fixed plate 510 drives the feeding hole 514 on the marking rod 508 to move out of the inside of the marking roller 504, thereby reducing the condition that the marking liquid flows out for a long time and is easy to cause loss. The arc surface of the marking rod 508 is fixedly installed with two fixed strips 512, the lower surface of the fixed strip 512 is fixedly installed with a round block 513, and the fixed strip 512 is made of tungsten.

The lower surface of the clamping plate 63 is fixedly installed with two fixed rods 77, one end of the fixed rod 77 is fixedly installed with a folding plate 78, the side wall of the folding plate 78 is fixedly installed with a sponge brush 79, the lower surface of the sponge brush 79 is provided with a groove, and the folding plate 78 is made of polypropylene plastic. The folding plate 78 on the fixed rod 77 can be folded and telescoped to drive the sponge brush 79 to abut against the cutting groove at all times, at this time the sponge brush 79 can further clean the fine residual chips in the cutting groove, the groove effectively improves the cleaning effect of the sponge brush 79, and reduces the situation that the fine residual chips remain in the cutting groove.

[0056] The method for using the laser engraving device, S1: the reinforcing steel bars are placed in the cutting groove of the workbench 1, the clamping device 6 can be used to clamp and position the reinforcing steel bars, thereby improving the clamping and positioning fixing work of reinforcing steel bars of different sizes;

[0057] S2: when cutting reinforcing steel bars with different size requirements, the marking device 5 is used to measure and mark the reinforcing steel bars, thereby improving the cutting efficiency of reinforcing steel bars of different specifications and sizes;

[0058] S3: the residual chips of the reinforcing steel bars in the cutting groove of the workbench 1 can be removed by the cleaning brush 72 on the cleaning device 7 driven by the clamping plate 63, thereby further improving the working efficiency of the laser engraving device;

[0059] S4: moving the reinforcing steel bars after the measurement and marking to the processing position can complete the cutting work of the reinforcing steel bars.

[0060] Working principle: in the cutting work of reinforcing steel bar, first put reinforcing steel bar into the cutting slot of the workbench 1, put one end of reinforcing steel bar under the marking rod 508, at this time start the second electric telescopic rod 62, the second electric telescopic rod 62 will push the clamping plate 63 to clamp reinforcing steel bar, so as to facilitate the clamping and limiting work of reinforcing steel bar of different sizes, when the clamping plate 63 clamps reinforcing steel bar, the anti-skid stripe 65 first contacts with reinforcing steel bar to carry out preliminary anti-skid work, with the gradual movement of the clamping plate 63, the tooth block 64 further clamps and limits reinforcing steel bar, so as to improve the fixing effect of reinforcing steel bar, at this time start the motor 67 in the fixing frame 66, the motor 67 drives the screw rod 68 to rotate, the screw rod 68 drives the clamping plate 63 on the supporting rod 61 to move, so as to improve the moving efficiency of reinforcing steel bar in the cutting slot, through the setting of the clamping device 6, the clamping and limiting effect of the laser engraving device on reinforcing steel bar is improved, the situation that the laser engraving device is difficult to clamp and limit reinforcing steel bar of different sizes is reduced, and the use efficiency of the laser engraving device is improved as much as possible.

[0061] The marking device 5 is installed beside the moving frame 3 with a specific size, and the marking roller 504 is set to a fixed size. First, the round cover 505 is rotated, the marking liquid is poured into the inside of the marking roller 504 from the feeding port, and then the round cover 505 is rotated to seal the marking liquid. At this time, the first electric telescopic rod 501 is started to drive the round rod 502 to move, the round rod 502 drives the cylinder 503 and the marking roller 504 to move and abut against the clamped steel bar. When the motor 67 drives the steel bar to move, the rolling bar 506 is in contact with the threads on the steel bar. At this time, the steel bar moves to drive the rolling bar 506 to rotate, and the rolling bar 506 in turn drives the marking roller 504 to rotate. The anti-skid groove 507 can effectively increase the friction between the rolling bar 506 and the steel bar. At this time, the marking roller 504 rotates one circle, the marking rod 508 gradually approaches the steel bar, the fixed bar 512 first abuts against the steel bar, and the round block 513 can effectively reduce the sliding instability of the fixed bar 512 when it contacts the steel bar. At this time, the fixed bar 512 is stressed to drive the marking rod 508 to retract into the inside of the marking roller 504, and the feeding hole 514 on the marking rod 508 moves into the inside of the marking roller 504. At this time, the marking liquid in the marking roller 504 flows into the sponge bar 509 through the feeding hole 514, and the sponge bar 509 fully absorbs the marking liquid. When the sponge bar 509 contacts the steel bar, the steel bar is marked. At this time, the size of the steel bar can be obtained by adding the size of the marking roller 504 and the distance between the moving frame 3 and the marking device 5, thereby facilitating the measurement and marking work of the steel bar. After the marking rod 508 rotates away from the steel bar, the elastic force of the first spring 511 pushes the fixed plate 510. At this time, the fixed plate 510 drives the feeding hole 514 on the marking rod 508 to move out of the inside of the marking roller 504, thereby reducing the waste caused by the long-time flow of the marking liquid. After the size to be cut is obtained, the motor 67 is controlled to stop working, and the moving frame 3 can be used to cut the steel bar. The fixed bar 512 is made of tungsten, and after the work is completed, the weight of the fixed bar 512 drives the marking rod 508 to vertically downward, thereby facilitating the measurement and marking work of the steel bar next time. By arranging the marking device 5, the cutting efficiency of the steel bar is improved, the situation that the laser engraving device is difficult to measure and cut the steel bars with different specifications is reduced, the measurement and marking work of the size of the steel bar is facilitated, and the working efficiency of the laser engraving device is improved as much as possible.
