[0003] For a long time, during the production of hot-dip galvanized steel pipes, in the process before packaging, the hot-dip galvanized steel pipes produced have to be marked. The method is to make a color band mark with a width of 40mm at a point 500mm away from one end of the outer surface according to the national standard; the traditional There are two methods used, one is to manually rub the steel pipe with the palms of both hands along the circumference, so that the surface of the steel pipe is coated with a ribbon on the circumference. The friction between the palm and the surface of the steel pipe will cause damage, and it needs to be replaced continuously, which is not suitable for continuous production; another method is to use a conical plug to enter the steel pipe under the action of gas pressure through a small cylinder. In the inner hole of the end head, the rotation of the conical head drives the steel pipe to rotate in the circumferential direction, and the steel pipe is in contact with the flexible color body in the color box, so that a certain width of the color band is coated on the surface of the steel pipe
Although this method eliminates the artificial fatigue and damage to the palm of the above-mentioned first coating ribbon in use, the operation procedure is cumbersome, and the cone head is often replaced due to wear and tear, and the inner surface of the steel pipe with different diameters and specifications The contact surface is small and the steel pipe does not rotate, so the operation of coating the ribbon cannot be realized

Embodiment Construction
[0018] The structure and working principle of the coating device for the hot-dip galvanized steel pipe marking tape provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 , 2 Shown is a schematic structural diagram of a coating device for a hot-dip galvanized steel pipe marking tape provided by the present invention. The structure of the coating device constituting the hot-dip galvanized steel pipe marking belt includes a frame and left and right steel pipe rolling rollers 1 arranged in parallel on both sides of the upper part and having a slope. The two rollers are respectively provided with grooves 15 to It is divided into two sections (or directly divided into two sections) of the sliding roller table 101 and the finished product roller table 102, and the ribbon box 13 constituting the coloring mechanism is fixed in the frame corresponding to the groove. Both sides are provided w...

The invention belongs to the technical field of auxiliary equipment for steel pipe machining, and particularly discloses a coating device for hot-galvanized steel pipe markers. The coating device structurally comprises a rack, a magnetic roll, a color coating mechanism and a support wheel mechanism, wherein a steel pipe rolling frame is arranged at the upper part of the rack, the magnetic roll driven by a power mechanism to rotate is arranged in the rack, the color coating mechanism is fixed in the rack and lower than the rack surface of the rack, and the support wheel mechanism which corresponds to the magnetic roll and is fixed by a shaft is arranged at the color coating mechanism. With the adoption of the coating device for the hot-galvanized steel pipe markers, an automatic marker coating function for hot-galvanized steel pipes can be realized, the labor intensity can be reduced substantially, and the labor efficiency can be improve effectively.
Description
technical field [0001] The invention belongs to the technical field of steel pipe processing auxiliary equipment, and in particular relates to a coating device for a hot-dip galvanized steel pipe marking tape. Background technique [0002] After the steel pipe is hot-dip galvanized, it is necessary to mark the hot-dip galvanized steel pipe. The main purpose is to identify a series of quality parameters of the hot-dip galvanized steel pipe, which is convenient for quality tracking and information feedback. According to the provisions of GB / T 2102-2006 "Acceptance, Packaging, Labeling and Quality Certificate of Steel Pipes", the mark is made at a point between 450~650mm from one end of the outer surface of the hot-dip galvanized steel pipe; the color of the mark can be determined according to the hot-dip galvanized The grade of zinc steel pipe shall be coated with the specified color. [0003] For a long time, during the production of hot-dip galvanized steel pipes, in the pr...
