Positioning device for manual silk-screen wheel transfer printing machine

Abstract

The invention discloses a locating device used for a manual silk screen and wheel-rotating printing machine, pertaining to a technical field of printing devices. The device includes an ink pad arranged on supporting legs and a screen board arranged on a rotary table by a cantilever; wherein, the outer end of the supporting leg is provided with a locating base which is provided with a transverse locating slot and a vertical locating slot. A pair of core shafts pass through the transverse locating slot and are fixedly installed in the slot, and the pair of core shafts are provided with a pair of bearings locked by nuts. The outer end of the otter board is provided with a locating plate which can be inserted into the vertical locating slot and the gap between the two bearings and can form leak proof fit with the bearings. The device can discover and correct the displacement of the screen board in time, therefore, the accurate locating and overprinting of the screen board and the ink pad can be ensured, the printing product has good quality and high level, the waste product is eliminated, the work efficiency is improved, and the manufacture cost is reduced greatly. The device can be used for monochromatic multi-color overprinting with clearance and zero-distance multi-color overprinting.

Description

1. Technical field: [0001] The invention relates to a manual screen rotary printing machine, more specifically a positioning device for the manual screen rotary printing machine. 2. Background technology: [0002] At present, the structure of the manual screen rotary printing machine is: a rotating shaft is installed on a base with a circular platen, and a circular turntable located above the circular platen is installed on the rotating shaft through a bearing, and the circular turntable can rotate around the rotating shaft turn. There are 8 cantilevers evenly arranged around the circumference of the circular turntable, and a screen plate is installed on the outer end of each cantilever; 8 supporting legs are evenly distributed on the circular platform, and each supporting leg is equipped with a printing pad. The screen plate can correspond up and down with the ink pad located below it. The inner end of each net plate is connected with the circular turntable through three...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the above-mentioned positioning device are: when the screen plate is manually rotated for positioning, the screen plate is easy to shift, resulting in accurate positioning and overprinting of the screen plate and the printing pad, resulting in overprint errors, resulting in a large number of waste products, reducing work efficiency, and increasing Manufacturing cost, poor quality and low grade of printed products, narrow printing range, only single-color or multi-color overprint with gaps
