[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1 to 6 As shown, an inkjet marking device for flaw detection of copper tubes of the utility model comprises a processing box 1, an inkjet box 11 and a drying box 12 are provided on the top of the processing box 1, a partition 13 is fixedly installed between the inkjet box 11 and the drying box 12, a material through hole 14 is provided on one side of the processing box 1 and the partition 13, a heating tube 3 is fixedly installed on the inner surface of the drying box 12, and the heating tube 3 is connected through two adjacent material through holes 14, and four supporting legs 101 are fixedly installed on the bottom of the processing box 1;

[0029] It also includes an inkjet mechanism for uniformly spraying ink on the copper tube;

[0030] The inkjet mechanism includes an ink cartridge 4, which is fixedly installed on one side of a processing box 1. One side of the ink cartridge 4 passes through the processing box 1 and is fixedly connected to a delivery pipe 41. The delivery pipe 41 is fixedly installed on the inner wall of the inkjet box 11. One side of the delivery pipe 41 is evenly and fixedly connected to four connecting pipes 425. One end of the connecting pipe 425 is fixedly connected to a nozzle 424. The nozzle 424 is slidably installed on one side of a driving disk 42. The driving disk 42 is rotatably installed on one side of a partition 13. The outer surface of the driving disk 42 is fixedly connected to a rack 43. The rack 43 is meshed with a gear 44. One side of the gear 44 is fixedly connected to a motor 45.

[0031] When a damaged copper tube is detected, in order to facilitate picking out the damaged copper tube when using it, it is necessary to perform inkjet marking on the damaged copper tube.

[0032] When the utility model is used, the copper tube is first placed in the material passage hole 14, and when a damaged copper tube is detected, the ink cartridge 4 supplies ink to the delivery tube 41. Then the delivery tube 41 supplies ink to the connecting tube 425, and finally the ink is sprayed on the damaged part of the copper tube through the nozzle 424 to mark the copper tube. Since the sizes of the marked copper tubes are different, when marking copper tubes of different diameters, the position of the nozzle 424 needs to be adjusted so that the nozzle 424 can mark the outer surface of the copper tubes of different diameters. First, the output shaft of the motor 45 drives the gear 44 to rotate, and the gear 44 meshes with the rack 43 to further drive the driving disk 42 to rotate. When the driving disk 42 rotates, the nozzle 424 will also move, so that the copper tubes of different sizes can be marked by inkjet. After the ink is sprayed on the surface of the copper tube, the ink on the copper tube can be dried by the heating tube 3.

[0033] Further, such as Figures 1 to 3 As shown, four slide grooves 15 are evenly formed on the outer surface of the processing box 1, and an ink inlet groove 16 is formed on one side of the processing box 1. Both sides of the ink inlet groove 16 are connected to the inner cavity of the ink cartridge 4 and the delivery pipe 41 respectively;

[0034] Two limiting wheels 26 are rotatably mounted on both sides of the processing box 1, and a rotating shaft 25 is fixedly connected to both sides of the limiting wheels 26. A slider 22 is rotatably mounted on one side of the rotating shaft 25, and a spring 24 is fixedly mounted on the opposite surfaces of the two sliders 22 on the same side, and a damper 23 is wound around the outer surface of the spring 24;

[0035] Two guard plates 2 are fixedly installed on both sides of the processing box 1. A first groove 21 is opened on one side of the guard plate 2. The slider 22 is slidably installed on the inner surface of the first groove 21. The diameter of both sides of the limiting wheel 26 gradually decreases toward the middle.

[0036] When the utility model is in use, the copper tube is first passed through the material passing hole 14. When the copper tube is inserted, part of the copper tube will be located between two adjacent limiting wheels 26. When the copper tube is inserted, the two adjacent limiting wheels 26 rotate. At the same time, under the joint action of the spring 24 and the damper 23, the limiting wheel 26 located on the upper side has a downward pressing force, so that the two limiting wheels 26 can clamp the copper tube. The two limiting wheels 26 in the inner cavity of the processing box 1 can make the copper tube in a horizontal state, which is convenient for the subsequent inkjet marking of the copper tube. When the copper tube is moved, the limiting wheel 26 will rotate with the copper tube, further avoiding damage to the copper tube caused by friction with the copper tube, thereby protecting the copper tube.

[0037] Further, such as Figure 4 and Figure 5As shown, four arc-shaped grooves 421 are evenly opened on one side of the driving disk 42, a slide rod 422 is slidably installed on the inner surface of the arc-shaped groove 421, a support block 423 is rotatably installed on the top of the slide rod 422, and the four support blocks 423 are respectively slidably installed on the inner surfaces of four slide grooves 15, and the nozzle 424 is fixedly installed on the top of the support block 423;

[0038] The ink jetting angles of the four nozzles 424 are all 90°, and the four nozzles 424 all spray ink toward the center of the four nozzles 424;

[0039] A fixing block 46 is fixedly connected to one side of the motor 45 . The fixing block 46 is fixedly installed on the inner wall of the inkjet box 11 . A collecting box 5 is fixedly connected to the bottom wall of the inkjet box 11 .

[0040] When the utility model is in use, when the output shaft of the motor 45 rotates with the gear 44, the gear 44 meshes with the rack 43 to drive the driving disk 42 to rotate. When the driving disk 42 rotates, the slide bar 422 slides on the inner surface of the arc groove 421, and the support block 423 slides on the inner surface of the slide groove 15. The slide groove 15 limits the support block 423. The support block 423 can only move in a straight line through the slide groove 15, thereby achieving the purpose of driving the nozzle 424 by moving the support block 423.

[0041] At the same time, through the cooperation of the four support blocks 423, any position on the outer surface of the copper tube can be marked by inkjet.

[0042] Further, such as Figure 6 As shown, an air outlet pipe 6 is fixedly installed on one side of the processing box 1, one end of the air outlet pipe 6 passes through the inner cavity of the processing box 1, and the other end of the air outlet pipe 6 is fixedly connected to a purification box 61, and activated carbon 62 is fixedly installed in the inner cavity of the purification box 61.

[0043] When the utility model is in use, the exhaust gas in the processing box 1 is first discharged through the exhaust pipe 6, and then the exhaust gas enters the purification box 61. The activated carbon 62 in the purification box 61 can adsorb the substances in the exhaust gas. At the same time, since there will be excess ink flowing down after inkjet, the excess ink is collected through the collection box 5, which is convenient for the staff to deal with the excess ink later, and then the ink can be recycled.

[0044] Working principle: First, place the copper tube in the inner cavity of the processing box 1 through the material hole 14. One side of the copper tube is restrained by four limiting wheels 26. The limiting wheels 26 located on both sides of the inner cavity of the processing box 1 can also keep the copper tube in a horizontal state. The damper 23 and the spring 24 can make the limiting wheel 26 on the upper side squeeze the copper tube downward. At the same time, the damper 23 and the spring 24 will not damage the copper tube, further protecting the copper tube. As the copper tube is pushed forward, the damaged part of the damaged copper tube moves to the nozzle. 424, the ink is output from the ink cartridge 4 to the delivery tube 41, and then the delivery tube 41 squeezes the ink into the connecting tube 425, and finally sprayed out through the nozzle 424, sprayed to the damaged part of the copper tube, marking the copper tube, and the position of the nozzle 424 can be adjusted according to the copper tubes of different sizes. First, the output shaft of the motor 45 drives the gear 44 to rotate, the gear 44 meshes with the rack 43, and drives the rack 43 to rotate, and the rack 43 further drives the driving disk 42 to rotate. When the driving disk 42 rotates, 422 slides on the inner surface of the arc groove 421, and the support block 423 slides on the inner surface of the slide groove 15, thereby realizing the adjustment of the position of the nozzle 424. Through the cooperation of the four nozzles 424, the entire outer surface of the copper tube can be sprayed with ink, and then the nozzle 424 can mark the damaged part of the copper tube with ink.

[0045] After the inkjet is completed, the copper tube will continue to move. When it moves to the inner cavity of the heating tube 3, the heating tube 3 heats and bakes the outer surface of the copper tube to dry the ink sprayed on the surface of the copper tube. At the same time, when the copper tube is inkjetted, the ink flowing from the copper tube will fall into the collecting box 5. After being collected by the collecting box 5, the subsequent staff can process the ink in the collecting box 5 and recycle the ink. When inkjet is sprayed, the air outlet pipe 6 can lead the ink in the inner cavity of the processing box 1, and the activated carbon 62 in the purification box 61 adsorbs the substances in the poisonous gas, and then the gas in the processing box 1 can be released to avoid pollution to the environment.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled 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 list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
