Selection of a qualified rotary die cutter machine has three key points must be grasped. First is the main configuration of the equipment, the second is the raw materials and processing precision in manufacturing equipment , third is the system of professional services. Among them, the equipment configuration will determine the advanced nature, practicality and reliability in the production process.
rotary die cutter is composed of three parts, die-cutter unit, feed unit, electrical control department. Die cutter uses soft cut currently,what is polyurethane rubber sleeve on the roller set a high strength. Soft roll in the process of die cutting machine rotation to move back and forth 40 mm at the same time, so that the die cutting knife to avoid duplication of the same position, resulting the rubber sleeve in a partial destruction . This kind of transverse shifting device has two main structures in China. There is a mechanical structure and is widely used, mainly through the roller speed ratio of difference, controled by a cam on the soft roll moving has the function of speed ratio control, so soft roll movement speed is determined according to the speed of the functioning of the equipment.
Rotary die cutter machine must be equipped with "the speed difference automatic compensation device". There is three modes with this device , one is the speed difference equalizer,but the price is high. One is the surface of the clutch speed compensation, more economical and practical. There is another way is to replace the gear, each repair a soft cover, the replacement of a gear, it is troublesome, and compensation is not accurate.
There is four points about the die cutter part main configuration , 1, the soft roller automatic repair device, 2, the speed difference automatic compensation device, 3, imports of soft cut rubber sleeve, 4, soft roll lateral movement device.
