A Symmetrical Double-Motion Platform Pressing Mechanism for a Horizontal Flat Die Cutting Machine

Abstract

The invention discloses a symmetrical double-moving-platform pressure applying mechanism of a horizontal platen die-cutting machine. The symmetrical double-moving-platform pressure applying mechanismcomprises a crankshaft, a left connecting rod hinged to the left end of the crankshaft is hinged to an upper left toggle rod and a lower left toggle rod, and a right connecting rod hinged to the rightend of the crankshaft is hinged to an upper right toggle rod and a lower right toggle rod; the upper left toggle rod and the upper right toggle rod are hinged to an upper moving platform, the upper moving platform is installed on a vertical guide rail of a machine body, and an upper static platform fixed on the machine body cooperates with the upper moving platform; the lower left toggle rod andthe lower right toggle rod are hinged to the lower moving platform, the lower moving platform is installed on the vertical guide rail of the machine body, and a lower static platform fixed on the machine body cooperates with the lower moving platform; and the crankshaft is rotated, so that the upper moving platform and the lower moving platform are driven to do up-and-down reciprocating rectilinear motion and cooperate with the upper static platform and the lower static platform to realize die cutting or hot stamping work. According to the symmetrical double-moving-platform pressure applying mechanism, unbalanced inertia force of the die-cutting machine during the working process can be eliminated, the die-cutting precision can be guaranteed, and the production efficiency of the platen die-cutting machine can be improved in a multiplied mode.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to a symmetrical double-action platform pressing mechanism of a horizontal flat die-cutting machine. Background technique [0002] Among the packaging and printing equipment, the automatic horizontal flat die-cutting machine is one of the models with wide application, high degree of automation and high technical content, and its high production efficiency and degree of automation are favored by manufacturers. With the continuous increase of people's demand for paper product packaging, the rapid development of the packaging and printing industry has put forward higher requirements for the production efficiency of paper product packaging equipment, and at the same time, it has also put forward a great test for the processing capacity and processing quality of the equipment. , so the working speed of the horizontal flat die-cutting machine design is continuously ...

AI Technical Summary

Problems solved by technology

[0003] 1. The horizontal and vertical inertial forces in the working process of the horizontal flat die-cutting machine are relatively large, with obvious fluctuations, and the fluctuation amplitude of the inertial force increases with the continuous increase of the working speed of the die-cutting machine, so that the horizontal The fuselage of the flat die-cutting machine produces serious vibration during the working process, which poses a safety hazard;

[0004] 2. When the working speed of the die-cutting machine is high, the die-cutting accuracy will be greatly reduced, accompanied by a lot of noise and impact, which will affect the service life of the machine;

[0005] 3. Due to the structural limitation of the pressure mechanism of the traditional horizontal flat die-cutting machine, the production efficiency of the horizontal flat die-cutting machine can only be improved by increasing the working speed, and the degree of improvement in production efficiency is limited
