Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production, in particular to a device for spraying markings on a full-length steel pipe with double nozzles. Background Art

[0002] The steel pipe marking should at least include the factory name, specification, material, implementation standard, meter length, weight, batch number, furnace number, bundle number, special marking and other information, and this information is traceable. Steel pipe marking is of great significance in product transshipment, sales, circulation and link identification. The traditional steel pipe factory uses a single nozzle to spray from one end of the steel pipe, and the nozzle runs all the way to the other end of the steel pipe. During the entire marking process, the nozzle travels a long distance, the cable length requirement is long, and the production rhythm time is long, resulting in low production capacity of the assembly line, shortening the life of the equipment, and when the nozzle equipment fails, production must be stopped to complete the maintenance. In order to solve the problem of stable improvement of full-length marking capacity and long equipment downtime, the solution has always been: speed up the motor travel speed, frequently replace the control cable, and frequently organize emergency repairs. The disadvantages of this solution are: the motor has a long travel distance and a short service life, the frequent travel interval of the cable leads to large consumption, the maintenance personnel have a large workload, and the marking quality is unstable.

[0031] Embodiment 2

[0032] This embodiment also provides a device for spraying marking on a steel pipe with two nozzles over the entire length of the steel pipe as in the first embodiment, comprising the following steps:

[0033] A gantry 1 is installed above the marking area. The gantry 1 is welded from steel plates. Figure 2 Rectangular structure, side length is 0.8*0.5m, length is between 13-15m. Gantry 1 falls on the first gantry 1 column and the second gantry 1 column on both sides of the spraying area. Figure 2The first slideway 9 and the second slideway 10 are of the same length, arranged up and down and parallel, and both of the first slideway 9 and the second slideway 10 extend from the head end to the tail end of the gantry 1. A rack 6 of the same length and parallel to the first slideway 9 is installed at the center position between the first slideway 9 and the second slideway 10, and the first rectangular fixed plate 7 is provided with a first walking wheel group and a second walking wheel group, and the second rectangular fixed plate is provided with a third walking wheel group and a fourth walking wheel group. The four walking wheel groups slide on the upper and lower first slideways 9 and the second slideway 10 respectively, and the first slideway 9 and the second slideway 10 play a guiding role. The center positions of the first rectangular fixed plate 7 and the second rectangular fixed plate are provided with screw holes, and the first servo motor 8 and the second servo motor are respectively installed through the screw holes. The output ends of the first servo motor 8 and the second servo motor are respectively provided with a first gear and a second gear, and the first gear and the second gear are meshed and connected with the rack 6 installed on the gantry 1. Under the action of the first servo motor 8 and the second servo motor, the first gear and the second gear and the rack 6 cooperate to complete the first rectangular fixed plate 7 and the second rectangular fixed plate walking on the slideway of the gantry 1. The first nozzle 4 is installed beside the first servo motor 8 on the first rectangular fixed plate 7. As the first rectangular fixed plate 7 moves, the first nozzle 4 can also move synchronously. During the moving process, the first nozzle 4 completes the steel pipe marking function.

[0034] The first rectangular fixed plate 7 and the second rectangular fixed plate on the gantry 1 respectively drive the first nozzle 4 and the second nozzle 5 to move. The first nozzle 4 and the second nozzle 5 start to run from the head and tail ends of a steel pipe at the same time. When they reach the middle position of the steel pipe, they are controlled to stop by the first limiter 11 and the second limiter 12 and the control system. Then the first nozzle 4 and the second nozzle 5 rise and wait to complete the full-length cycle marking. When the next pipe arrives, the first nozzle 4 and the second nozzle 5 fall from the center of the steel pipe, start to move backwards, complete their respective marking contents in turn, reach the head and tail ends of the steel pipe respectively, and are controlled to stop by the first limiter 11 and the second limiter 12 and the control system. Then the first nozzle 4 and the second nozzle 5 rise again and wait for the next operation. The first nozzle 4 and the second nozzle 5 only run half of the length of the steel pipe, and the life of the motor is extended. The length of the cable used is shortened by half, so the number of cable failures caused by long-distance operation is reduced and the life is extended. The power-on operation time of the nozzle is shortened, the nozzle is in good condition, and the marking quality is steadily improved.

[0035] The first nozzle 4 on the first rectangular fixed plate 7 and the second nozzle 5 on the second rectangular fixed plate are placed on the same horizontal plane through the first slide 9 and the second slide 10, ensuring that the logos printed by the two are in a straight line, thereby improving the aesthetics and standardization of product logos.

[0036] The first nozzle 4 and the second nozzle 5 complete the full-length marking printing by synchronously operating in two modes: facing printing and back-to-back printing.

[0037] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
