Ductile iron pipe with two-dimensional code pipe number pattern, spraying system and production method

Abstract

The invention discloses a nodular cast iron pipe with a two-dimension code pipe number pattern, a spraying system and a production method. The method comprises the following steps that a nodular cast iron pipe body is moved to a code spraying station to wait for being sprayed; a control system is operated to control mechanisms on a cross sliding table and framework to move, a two-dimension code spray printing machine is moved to the pipe number spraying position along a horizontal sliding table, the vertical position of the two-dimension code spray printing machine is adjusted, the spraying distance is made to be proper, then automatically increased pipe numbers are sprayed, and finally spraying control software in the two-dimension code spray printing machine controls the two-dimension code spray printing machine to spray the automatically generated two-dimension code pattern to the outer surface of the nodular cast iron pipe body; the two-dimension code pipe number information is read through a two-dimension code reading device and is transmitted to a nodular cast iron pipe quality information management database to be stored. The outer wall of the nodular cast iron pipe is coated with the two-dimension code pipe number pattern, so that the requirement for automatically collecting the pipe numbers by a computer is met, and the quality management and control level of the nodular cast iron pipe is improved.

Description

technical field [0001] The invention relates to the technical field of ductile iron pipes, in particular to a ductile iron pipe with a two-dimensional code pipe number pattern, a spraying system and a production method. Background technique [0002] For a long time, the spraying of the pipe number on the outer surface of the ductile iron pipe has adopted the method of template engraving, that is, artificially engraving the commonly used and invariable alphanumeric sequences on the metal mother board, such as the standard number, enterprise standard and unit name implemented, while for For frequently changing batch numbers and pipe numbers, select the corresponding number on another metal mother board and select the spraying method bit by bit to realize the spraying of different cast pipes and different pipe numbers. This is a traditional spraying method for ductile iron pipe numbers, which has the advantages of simple operation and is widely used in cast pipe manufacturers. ...

Problems solved by technology

However, in this method, due to the fact that the mother plate and the ductile iron pipe wall are difficult to be completely adhered to, the sprayed paint tends to spread around the sprayed pipe number, resulting in the blurring of the sprayed writing; in addition, special spraying is required, resulting in increased labor costs
