Screen printing method for special-shaped cone workpiece and printing equipment thereof

Abstract

The invention relates to a special-shaped cone workpiece silk-screen printing method and equipment, and the method comprises the steps: enabling the side surface of a cone workpiece to be attached to the lower surface of a silk-screen plate, enabling a scraper to be attached to the upper surface of the silk-screen plate in place for scraping ink, and further setting a printing base line on the silk-screen plate, the first executing mechanism drives the silk-screen plate to do arc motion in the horizontal plane, the second executing mechanism drives the conical workpiece to rotate and enable the conical workpiece and the silk-screen plate to do synchronous motion at the same linear speed in the arc motion process of the silk-screen plate, and meanwhile the third executing mechanism drives the silk-screen plate to do horizontal self-rotation. The printing base line and the generatrix of the conical workpiece coincide constantly, then high-precision printing of the conical workpiece is achieved, the good font deformation prevention effect is achieved, the scraper does not need to move in the whole process, and the defect that the size of equipment is too large due to the fact that a traditional printing mode is influenced by the shape of the workpiece is directly overcome.

Description

technical field [0001] The invention relates to the technical field of screen printing, in particular to a screen printing method for a special-shaped cone workpiece and a printing device thereof. Background technique [0002] Screen printing consists of five elements, namely screen printing plate, squeegee, ink, printing table and substrate. The basic principle of screen printing is to use the basic principle that the mesh of the graphic part of the screen printing plate is transparent to the ink, and the mesh of the non-graphic part is not permeable to the ink. advantages and are widely used. [0003] In recent years, the conical flask has been loved by the majority of users because of its unique shape and certain practical value. In order to pursue individual design and brand promotion, users often print various patterns on the bottle of the conical flask. However, the existing screen printing machine can only meet the printing of cylindrical or flat objects, and for th...

Problems solved by technology

[0003] In recent years, Erlenmeyer flasks have been favored by users because of their unique shape and certain practical value. In order to pursue individual design and brand promotion, users often print various patterns on the body of the Erlenmeyer flasks. However, the existing screen printing machines can only print cylindrical or flat objects, and for conical bottles, the pattern printed on the bottle body is often compressed or stretched, which affects the printing quality of the pattern. The surface printing of conical objects generally moves on the screen in the way of scraper deflection, and the deflection of the scraper is generally realized by rotating a swing arm around a fixed point. The length of the swing arm and the distance from the fixed point to the screen depend on The taper of the product itself leads to low compatibility of the equipment, and the equipment is bulky and occupies a wide area, which is not conducive to the on-site layout of enterprise users. Therefore, we specially propose a screen printing method for special-shaped cone workpieces and its printing equipment to solve the above problems
