Printing device for surfaces of PE pipes and printing method thereof

Abstract

The invention discloses a printing device for the surfaces of PE pipes and a printing method thereof, and relates to the technical field of PE pipe processing. The printing device comprises a base, wherein a group of support columns which are in rectangular distribution are fixedly connected to one surface of the base, a fixed seat is fixedly connected to one surface of the group of support columns, a threaded lead screw is rotatably connected to the inner wall of the fixed seat, a driving motor is fixedly connected to one surface of the fixed seat, one end of an output shaft of the driving motor is fixedly connected with the threaded lead screw, a movable seat is in threaded connection to the circumferential side surface of the threaded lead screw, and a connecting plate is fixedly connected to one surface of the movable seat. According to the printing device, the fixed seat, the movable seat, a polishing assembly, a cleaning assembly and a curved screen printing machine are designed,so that the problem of poor printing effect caused by non-printing areas which need to be printed on the surfaces of the PE pipes due to impurity falling when the PE pipes are moved and transferred after printing is completed because multiple impurities and attachments adhere to the surfaces of the PE pipes which are printed by an existing printing device is solved.

Description

Technical field [0001] The invention belongs to the technical field of PE pipe processing, and particularly relates to a PE pipe surface printing device and a printing method thereof. Background technique [0002] PE pipes are used in a wide range of fields, of which water supply pipes and gas pipes are its two largest application markets. PE resin is polymerized from monomer ethylene. Due to the different polymerization conditions such as pressure and temperature during polymerization, it can be obtained Different densities of resins are produced, so there are high-density polyethylene, medium-density polyethylene and low-density polyethylene. When processing different types of PE pipes, according to the different application conditions, different resin grades are selected, and the extrusion The requirements of the machine and the mold are also different. Internationally, the materials of polyethylene pipes are divided into five grades: PE32, PE40, PE63, PE80, PE100, and the mat...

Problems solved by technology

[0004] The object of the present invention is to provide a PE pipe surface printing device and its printing method. Through the design of the fixed seat, the moving seat, the polishing assembly, the cleaning assembly and the curved surface screen printing machine, the problem of printing the PE pipe by the existing printing device is solved. When the PE pipe surface is stuck with many impurities and attachments, after the printing is completed, the PE pipe will be transported and transferred, and the impurities will fall off, which will cause the area on the surface of the PE pipe that should be printed to not be printed, thus making the printing effect better. bad question
