Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of inkjet coding and conveying, and specifically, to an inkjet coding and conveying device for galvanized pipe production. Background Art

[0002] Galvanized pipes are common pipes in the prior art. A galvanized pipe refers to a welded steel pipe with a hot-dip galvanized or electro-galvanized layer on the outer side of a common steel pipe. By processing a galvanized layer on the outer layer of the steel pipe, the corrosion resistance of the steel pipe can be effectively improved. Among them, because galvanized pipes generally undertake long-distance transportation operations of liquids and gases in real life, the produced galvanized pipes generally have a certain length.

[0003] During the process of galvanized pipe completing the galvanizing operation on the galvanizing production line, a dedicated inkjet coding and conveying device is generally equipped on the galvanizing production line. During the process of moving the galvanized pipe, in the form of spraying ink on the galvanized pipe, the basic information for recording the length, product specifications, and manufacturer of the galvanized pipe is marked on the surface of the galvanized pipe, which is convenient for subsequent determination of the length and size of a single galvanized pipe and targeted use of the galvanized pipe.

[0004] Before the galvanizing operation of the galvanized pipe in the prior art, it is already necessary to perform a cutting operation on the galvanized pipe to produce a batch of galvanized pipes with nearly equal lengths. And the inkjet coding and conveying devices in the prior art generally perform a whole-meter inkjet coding operation on the galvanized pipe, that is, add inkjet codes to the galvanized pipe every one meter, two meters, or half a meter. However, for the length of the tail section of the galvanized pipe, the actual length is not detected. Therefore, during subsequent construction, when the galvanized pipe is cut and used, it is still necessary to measure again at the construction site to determine the length of the used galvanized pipe, which affects the practicability of the inkjet coding and conveying device for measuring and inkjet coding the length of the galvanized pipe.

[0029] Elastic length measuring components 400 are arranged on both sides of the bottom of the inkjet head 5.

The elastic length measuring components 400 move horizontally and vertically in synchronization with the inkjet head 5. The bottom of the sliding through groove 18 is slidably connected through an installation plate body 20. The installation plate body 20 is fixedly connected to the bottom of the inkjet head 5. The two elastic length measuring components 400 are respectively arranged on both sides of the installation plate body 20. During the descending process of the inkjet head 5, it will drive the installation plate body 20 and the elastic length measuring components 400 to descend at the bottom of the sliding through groove 18, so that the length measuring wheel 25 is in contact with the top of the pipe; The elastic length measuring component 400 includes a rotating groove frame 21 and a connecting arm 24. The rotating groove frame 21 is fixedly connected to the bottom of the installation plate body 20. A rotating shaft 22 is rotatably connected in the rotating groove frame 21.

A length measuring wheel 25 is arranged at the bottom of the connecting arm 24. An encoder 26 is arranged on the length measuring wheel 25. During the movement of the pipe, the actual length is measured by the length measuring wheel 25 and the encoder 26. During the lateral movement of the pipe, because the length measuring wheel 25 is in contact with the top of the pipe, when the pipe moves laterally, it drives the length measuring wheel 25 to rotate, and the encoder 26 can calculate the length of the pipe according to the rotation circumference of the length measuring wheel 25. The encoder 26 and the inkjet coding device 2 use electrical signal transmission to transmit the length of the pipe measured by the encoder 26 into the inkjet coding device 2, and the inkjet coding device 2 then controls the inkjet head 5 to ink-jet mark the surface of the pipe.

[0030] Working principle of the inkjet coding and conveying device for galvanized pipe production: Move one end of the galvanized pipe to the top of multiple supporting rollers 7, and then start the third electric cylinders 27 on both sides to drive the slope-shaped sliding groove frames 8 to move on the top of the supporting groove frame 6, so that the two slope-shaped sliding groove frames 8 move towards the bottom of the pipe. The rotating wheels 10 are in contact with the outer wall of the pipe. Multiple mounting grooves 9 are arranged obliquely on the slope-shaped surface of the slope-shaped sliding groove frame 8. During the movement of the slope-shaped sliding groove frame 8 towards the pipe, the rotating wheels 10 are in contact with the outer wall of the pipe. Start the first electric cylinder 12 to drive the fixed socket 15 to descend, so that the rotary driving device 13 squeezes the top of the pipe, and use the rotary driving device 13 to drive the pipe to move onto the pipe conveying device 1.

[0031] Make the length measuring wheel 25 contact with the surface of the pipe, and move the inkjet head 5 to a suitable inkjet coding height with respect to the pipe. When the pipe moves horizontally, it drives the length measuring wheel 25 to rotate. The encoder 26 can measure the length of the pipe according to the rotation circumference of the length measuring wheel 25. The encoder 26 and the inkjet coding device 2 are connected by electrical signal transmission, and the length of the pipe measured by the encoder 26 is transmitted into the inkjet coding device 2, and then the inkjet coding device 2 controls the inkjet head 5 to ink-jet mark the surface of the pipe.

[0032] After the tail section of the pipe moves into the pipe moving chamber 4, drive the inkjet head 5 and the length measuring wheel 25 to move through the lead screw transmission mechanism. During the horizontal movement of the length measuring wheel 25, the length measuring wheel 25 also rotates to measure the length of the tail section of the pipe. Then, make the inkjet head 5 measure the length of the tail section of the pipe, and then use the inkjet head 5 to mark the length of the tail section of the pipe on the pipe.

[0033] It should be further supplemented that the distances between the two length measuring wheels 25 and the inkjet head 5 are equal. Therefore, after the inkjet coding device 2 is reset to zero, the values of the two encoders 26 are adjusted in positive and negative directions respectively. When detecting the length of the tail section of the pipe, completely move one of the length measuring wheels 25 away from the tail section of the pipe to judge the actual length of the tail section of the pipe, and make the inkjet head 5 mark the length of the tail section of the pipe.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
