Energy-saving metal printing plate hardness detection device

Abstract

The invention relates to the technical field of printing plate manufacturing, in particular to an energy-saving metal printing plate hardness detection device which is characterized in that a first gear is movably connected to one end of a rotating shaft and located on the front surface of a fixed plate, a chain is meshed with the outer surface of the first gear, and a second gear is meshed with the other end of the chain; a first connecting rod is movably connected to the upper surface of the first gear, a pressure mechanism is fixedly connected to the bottom of the first connecting rod, thefirst gear and the second gear are connected through a chain, and the second gear drives a conveying belt with the meshed bottom to intermittently move under driving of a motor. The effect of pushingthe printing plate to move automatically and conducting stamping detection is achieved, potential safety hazards are reduced, and due to the fact that the three pressing rods are connected to the topof the pressing plate in the pressure mechanism, when the pressing plate conducts stamping downwards, the second pressing rod can decompose the vertically upward reacting force acting on the first pressing rod, and the pressing rod is protected against damage.

Description

technical field [0001] The invention relates to the technical field of printing plate production, in particular to an energy-saving metal printing plate hardness testing device. Background technique [0002] The printing plate is referred to as the printing plate, which is used to transfer the ink to the carrier of the printed image on the substrate. The printing plate can be divided into four types: letterpress, gravure, lithographic and stencil. The printing plate usually used for lithographic printing is made of metal. During the production of metal printing plates, the hardness of the printing plates needs to be tested to ensure normal operation during use. [0003] The existing device for testing the hardness of the printing plate needs to manually place the printing plate under the stamping machine for stamping, which has a large safety hazard, and the process is slow, which affects the detection efficiency. Secondly, the stamping plate The pressure generated by punch...

Problems solved by technology

[0003] The existing device for testing the hardness of the printing plate needs to manually place the printing plate under the stamping machine for stamping, which has a large safety hazard, and the process is slow, which affects the detection efficiency. Secondly, the stamping plate The pressure generated by punching the printing plate vertically downward is too high, and the vertical upward produces a large reaction force, which may damage the pressing plate. Therefore, those skilled in the art provide an energy-saving metal printing plate hardness testing device to solve the above problems. Questions raised in the background art
