With the development of the die cutting industry continues to mature, the common die cutting equipment is also constantly changing. Domestic commonly used die cutting equipment from the most traditional old plate die cutting machine, plate hot stamping die cutting machine, hot press die cutting machine, single seat die cutting machine, double seat die cutting machine, hole sleeve die cutting machine developed to intermittent rotary die cutting machine, full rotary die cutting machine, with the continuous change and maturity of die cutting product process, the function of the die cutting machine is also becoming higher and higher requirements. As a kind of high efficiency and high cost operation equipment in the die-cutting industry, the unique performance of the circular knife machine also reflects its unique advantages.

Machining principle of rotary die cutting machine

rotary die cutting machine is a die cutting machine, full known as "multi-station rotary die cutting machine", referred to as rotary, commonly known as round knife machine, hob machine or round knife die cutting machine. It in the form of hob continuous rotation die-cutting processing, die-cutting machine is one of the highest production efficiency of the machine. Divided into 2 seats, 3 seats, 5 seats, 7 seats and other series of circular cutter machine models. rotary die cutting machine is to achieve the purpose of die cutting through the blade and the roller extrusion material, the roller is a smooth surface and hard cylindrical shaft, round knife processing is in a process to complete the composite and processing of multi-layer material die cutting method.

At present, from the point of view of the tension control system of the multi-station circular knife machine, it is generally divided into two kinds: one is to use the program automatic tension control, through the pre-set program, automatically calculate the size of the winding shaft and calculate the torque in time, so as to ensure the stability of the tension. Automatic tension control system is widely used in Europe and America. In the view of many operators, the advantages of automatic tension control system are very obvious, such as the material does not need to be wound multiple times; Reduce material scratching and deformation; The operation is simple and convenient, and the program is easy to upgrade.

This is the basic processing principle of the circular die cutting machine.
