The two third cylinders 651 are fixedly arranged on two opposite inner side walls of the mounting frame 61, the two third cylinders 651 and the copper pipe are positioned on the same horizontal plane, and the two third cylinders 651 are electrically connected with the two copper pipe flaw detectors 51; the roller 652 is rotatably provided on a piston rod of the third cylinder 651, and the punch protrusions 653 are integrally formed on the peripheral surface of the roller 652. When the copper pipe flaw detector 51 detects a damaged part of the copper pipe, an electric signal is sent to the third air cylinder 651, when the damaged part reaches the inside of the mounting frame 61 and the third air cylinder 651 is about to face the damaged part, the third air cylinder 651 extends, and the stamping bulge 653 just abuts against the damaged part to form a recess. The formation of the recess is convenient for workers to identify the position of a damaged part, and the probability that ink is scraped and wiped off is reduced; the rollers 652 are configured to reduce the impact of the punch protrusions 653 on the moving copper tubing

The working principle of the embodiment is as follows:

when the copper pipe is not detected by the detection piece 38, the operation of the pinch motor 231 is stopped, one end of a new copper pipe in the material placing frame 21 penetrates through the loop device 22 and then is inserted into the box body 31, then the first cylinder 351 is started to push the placing plate 33 upwards until the first clamping piece 341 and the second clamping piece 342 are contacted with the two copper pipes, then the second cylinder 352 is started, the second cylinder 352 pushes the first clamping piece 341 and the second clamping piece 342 to be spliced, the splicing block 361 is inserted into the splicing groove 3421, and the locking rod 362 is inserted into the locking groove 3422. Then, the pinch motor 231 is started to feed.

When passing through the copper tube flaw detector 51, if no abnormality is detected, the ink jet tube 62 does not jet ink; if an abnormal condition is detected, an electric signal is sent to the third air cylinder 651 and the pump 64, when the copper pipe enters the mounting frame 61 and the third air cylinder 651 is about to face the damaged part, the third air cylinder 651 extends, and the stamping bulge 653 just props against the damaged part to form a recess; the pump 64 is then activated and the ink jet line 62 ejects ink into the depression.

And then dried by the drying device 25. When the first jaw 341 and the second jaw 342 move to the guide nozzle 373, the unlocking rod 371 is pressed into the through hole 3423 by the inner wall of the guide nozzle 373, the unlocking rod 371 pushes the locking rod 362 out of the locking groove 3422, and the first jaw 341 and the second jaw 342 are separated and fall onto the object placing plate 42. New copper tubing is guided by the guide nozzle 373 into the cutting device 26.

The pressure sensor 45 of the object placing plate 42 senses the increase of the pressure, the motor 443 is started, the conveyor belt 41 starts to move, so that the object placing plate 42 is conveyed to the proximity switch 43 of the box 31, the proximity switch 43 is triggered, the motor 443 stops moving, the first jaw 341 and the second jaw 342 are then removed, and then the motor 443 starts to move again until another object placing plate 42 moves to the proximity switch 43 and stops.

The worker pulls out the sliding frame 32, puts the first clip 341 and the second clip 342 on the placing groove 331 of the placing plate 33, and presses the sliding frame 32 back to the box body 31 to wait for the next operation.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
