[0019] See also Figure 1-4 , the utility model provides the following technical solutions:

[0020] A coding device for an extruded tube comprises a frame 1, a supporting roller 2 and a conveying mechanism 3, wherein the supporting roller 2 is rotatably connected to the frame 1, and the frame 1 is provided with a conveying mechanism 3 for conveying the extruded tube, and the conveying mechanism 3 comprises a slide rail 31, a conveying frame 32 and a conveying wheel 33, wherein the slide rail 31 is installed on the frame 1, and the conveying frames 32 are slidably connected to the two sides of the slide rail 31, respectively, and a plurality of conveying wheels 33 are vertically installed on the conveying frame 32, and a conveying belt 34 is connected to the conveying wheel 33, and a driving motor 35 for driving the conveying wheel 33 to rotate is installed on the conveying frame 32; the structural shape of the conveying frame 32 is set as a "U"-shaped structure, and through the design of the "U"-shaped structure, the conveying frame 32 can shield the conveying wheel 33 and the conveying belt 34, thereby improving the safety of the device; through the arrangement of the vertical conveying wheels 33 and the conveying belt 34, it is convenient to convey extruded tubes of different diameters.

[0021] A spacing adjustment mechanism 4 for adjusting the conveying spacing is provided below the conveying mechanism 3, and the spacing adjustment mechanism 4 includes a lead screw 41 and a hand wheel 42. Both ends of the lead screw 41 are rotatably connected to the frame 1, and the lead screw 41 is threadedly connected to a threaded hole provided below the conveying frame 32. One end of the lead screw 41 is keyed to the hand wheel 42, and threads with opposite thread rotation directions are provided on both sides of the lead screw 41. The purpose of this setting is that when the lead screw 41 is rotated, the conveying frames 32 on both sides of the lead screw 41 can move closer to or away from each other to achieve the adjustment of the spacing.

[0022] The frame 1 is provided with a mounting frame 5, a lifting rod 6 is vertically slidably connected to the mounting frame 5, a coder 7 is mounted on the lower end of the lifting rod 6, and a synchronous lifting mechanism 8 is mounted on the mounting frame 5 for synchronously adjusting the height of the coder 7 according to the conveying spacing; the synchronous lifting mechanism 8 comprises a gear 81, a lifting rack 82 and a driving frame 83, the gear 81 is rotatably connected to the mounting frame 5, a lifting rack 82 meshing with the gear 81 is mounted on the lifting rod 6, a driving frame 83 is connected to the conveying frame 32 on the rear side of the frame 1, and a horizontal rack 84 meshing with the gear 81 is mounted on the driving frame 83; the synchronous lifting mechanism 8 can synchronously control the position of the coder 7 by adjusting the spacing of the conveying mechanism 3, and the extrusion tube processing model can be quickly switched without adjusting the coder 7 separately.

[0023] The working process of the utility model is as follows:

[0024] When the extruded tube needs to be processed by inkjet coding, the extruded tube is pushed between the two conveyor belts 34, and the driving motor 35 drives the conveying wheel 33 to rotate. The conveying wheel 33 drives the conveyor belt 34 to move to transport the extruded tube. At the same time, the inkjet printer 7 performs inkjet coding on the surface of the extruded tube.

[0025] When it is necessary to inkjet code extruded tubes of different sizes and models, first place the extruded tube on the supporting roller 2, turn the hand wheel 42 to drive the lead screw 41 to rotate, and the lead screw 41 drives the conveying frames 32 on both sides to move closer to each other under the action of the thread, so that the conveyor belt 34 on the conveying frame 32 contacts with both sides of the extruded tube with appropriate pressure, thereby completing the adjustment of the spacing of the conveying mechanism 3.

[0026] During the movement of the conveying frame 32, the conveying frame 32 drives the horizontal rack 84 to move through the driving frame 83, the horizontal rack 84 drives the gear 81 to rotate, and the gear 81 drives the lifting rod 6 to move downward through the lifting rack 82, so that the inkjet printer 7 at the lower end of the lifting rod 6 maintains an appropriate working distance with the surface of the extrusion tube, thereby realizing the synchronous and rapid adjustment of the position of the inkjet printer 7.
