Abstract

The invention discloses a magnetic positioning device on a surface plate screen process press. The magnetic positioning device on the surface plate screen process press comprises a fixed support, a magnetic stripe, a light sensation device, a fan-shaped air cylinder, a support frame, connecting rods and stopping plates, wherein the stopping plates are arranged at both ends of the magnetic positioning device. The magnetic stripe is fixed on the fixed support which is fixed on a rack of a conveyor belt of a press or on a press rack, the light sensation device is fixed on the press rack above the end portion of the support, the fan-shaped air cylinder is fixed on the support frame below the fixed support, piston rods of both ends of the fan-shaped air cylinder are respectively connected with the connecting rods, the connecting rods are respectively connected with the stopping plates, and the fan-shaped air cylinder is electrically connected with the light sensation device. The magnetic positioning device is simple in equipment, small in size, low in construction cost, and high in magnetic positioning accuracy, is easily installed and used on common surface plate screen equipment, does not change an existing surface plate screen structure and process, and simultaneously enables magnetic screen printing ink to produce a vision anti-fake effect which can roll a line.

Description

technical field [0001] The invention relates to a sheet-fed flat-screen screen printing machine, in particular to a magnetic positioning device on the flat-screen screen printing machine. Background technique [0002] Magnetically aligned pigment particles during printing and curing are already known in the protection of value documents. Specific magnetic equipment and methods for manufacturing the security feature are also known, but in the known technology, the screen equipment used for the security element of paper securities is mostly a rotary drum type equipment with a complicated structure. For example, Chinese patent 200480018424.5 describes a rotary screen device with magnetic positioning. In this patent, the paper is stationary relative to the magnet, that is, the magnet is fixed on the roller and moves synchronously with the paper. This requires relatively complicated equipment components and high equipment precision, and it cannot be realized on ordinary flat scr...
