Abstract

The main transmission and conversion mechanism for automatic die cutting and thermoprinting machine includes pedestal, movable platform, four upper shaft seats connected to the movable platform and four toggle rod upper shafts, and features that between the four toggle rod upper shafts and the pedestal one combination of four conjugated cams and one lower toggle rod transmission mechanism are installed. The present invention has smart design of converting the rotation of conjugated cams into vertical straight line motion to make the platform obtain sufficient staying time in the highest point and the lowest point and fast ascent and descent speed and to meet the special technological requirement for pressing and gold stamping. The present invention has simple and compact structure, high processing quality, high production efficiency and wide application foreground.

Description

(1) Technical field: [0001] The invention relates to a post-printing mechanical equipment, in particular to a main drive conversion mechanism in a flat-press automatic die-cutting hot stamping machine that converts the rotational motion of a shaft into the up-and-down linear motion of a platform through a mechanism. (two) background technology: [0002] At present, with the development of the printing and packaging industry, especially the requirements for post-press equipment are getting higher and higher. This requirement is not only a requirement for precision, but also a requirement for speed. The speed factor of the equipment is limited by the transmission structure of the original mechanism, especially in embossing and hot stamping processes. First, it takes a period of time to maintain the pressure at the highest point of the moving platform, which is the most important in the crankshaft and connecting rod mechanism. Impossible to realize; Secondly, it is also difficu...
