A high-precision curved surface screen printing machine

Abstract

The invention relates to a high-precision curved surface screen printing machine. The high-precision curved surface screen printing machine comprises a machine frame, a material scraping mechanism, a horizontal moving mechanism, a silk screen support assembly and a supporting mechanism. The material scraping mechanism comprises a material scraping air cylinder, a material returning air cylinder, a scraper blade and a return plate. The horizontal moving mechanism comprises guide rods, a sliding block and a linear moving assembly. The silk screen support assembly comprises a silk screen support, a silk screen, a lifting air cylinder and a rack. The supporting mechanism comprises a vertical moving assembly, a driven assembly and a fixing assembly. The vertical moving assembly comprises a second motor, a lead screw and a moving block. The driven assembly comprises a supporting rod and a round gear. The fixing assembly comprises a supporting disc, clamping air cylinders and clamping parts. The high-precision curved surface screen printing machine is used for printing of cylindrical workpieces. By means of engagement between the gear and the rack, high precision is ensured during printing of cylindrical workpieces, and the printing quality is guaranteed. In addition, due to the fixing mechanism and an anti-dropping mechanism, the high-precision curved surface screen printing machine can be used for machining workpieces in different sizes, and workpieces can be prevented from dropping or loosening in the printing process.

Description

technical field [0001] The invention relates to the field of screen printing equipment, in particular to a high-precision curved surface screen printing machine. Background technique [0002] The full name of the screen printing machine is "screen printing machine". It is a machine for printing text and images. Its working principle is: firstly, the text and images to be printed are made into a printing plate, and then ink or solder paste is applied manually or by machine. Applied in place of text and images on the printing plate, it is directly or indirectly transferred to paper or other printing materials, such as textile boards, metal plates, plastics, leather, wood boards, glass and ceramics, so as to print Produce the same print as the printing plate. [0003] Screen printing machines can be roughly divided into flat screen printing machines and curved screen printing machines. As long as curved screen printing machines are used to print labels on cylindrical workpiece...

AI Technical Summary

Problems solved by technology

[0003] Screen printing machines can be roughly divided into flat screen printing machines and curved screen printing machines. As long as curved screen printing machines are used to print labels on cylindrical workpieces, most of the existing curved screen printing machines have the following problems: 1. The workpiece is in the process of rotating printing easy to fall off

2. The workpiece is easy to slip when it is rotated and printed, which will cause deviations in the printed pattern or text

3. The scalability is poor, and the general curved screen printing machine can only process specific workpieces
