[0027] The POM pad plate 4 adopts an arc-shaped structure, guarantees sufficient contact with the co-extrusion strip pipe 9 and guarantees a supporting effect, the POM pad plate 4 is connected and fixed with the POM pad plate support 8 through two internal hexagonal screws, the POM pad plate support 8 is connected and fixed with the general support plate 13 through four external hexagonal screws, the color mark sensor support 5 is connected with the POM pad plate support 8 through welding, and the color mark sensor 6 is connected and fixed with the color mark sensor support 5 through two internal hexagonal screws; the polyurethane pad 28 is connected and fixed with the general support plate 13 through three internal hexagonal screws.

[0028] The main working mode is that the set seat cabinet, the general support plate, the advancing cylinder, the wear-resistant rubber belt, the POM pad plate, the servo motor, the ink-jet printer nozzle and the like are combined together, the servo motor fixing base bottom and side are provided with sliders, the advancing cylinder is used to move forward and backward on the slide rail on the general support plate, and a practical and strong co-extrusion strip pipe automatic rotating ink-jet printer is formed.

[0030] The specific implementation process of the device in the production process is as follows: when the pipe 9 with a co-extrusion strip is conveyed from the previous conveying mechanism and detected by the photoelectric switch 22, the previous conveying mechanism stops conveying, and then the advancing cylinder 16 acts to lift and drive the servo motor fixed seat 11 to move forward. At this time, the polyurethane pad 28 plays a buffering role.

The movement of the wear-resistant rubber belt 18 drives the pipe 9 to rotate. In the rotating process of the pipe 9 with a co-extrusion strip, the color sensor 6 senses the co-extrusion strip which is inconsistent with the color of the pipe. At this time, the servo motor 10 stops operating, and at the same time the advancing cylinder 16 drives the servo motor fixed seat 11 to return to the original position. The pipe 9 with a co-extrusion strip is rotated to a fixed position, which ensures that the spray code sprayed by the nozzle 24 of the code jetting machine does not spray on the co-extrusion strip. Then the previous conveying mechanism operates to continue conveying the pipe 9 with a co-extrusion strip forward, and at the same time the code jetting machine 24 starts to jet and print. The next traction conveying mechanism operates to pull and send out the pipe 9 with a co-extrusion strip. Then the device waits for the arrival of the next pipe 9 with a co-extrusion strip. The device is complete.
