Die Cutting Machine Should Pay Attention To And Solve The Seven Major Problems

First, the equipment parts processing quality and assembly accuracy

Restricted by the technical level of domestic machinery manufacturing, Die Cutting Machine, many parts of rough processing. Such as the intermittent mechanism and the main drive system and the chain between the matching and manufacturing accuracy directly affect the machine speed, if the assembly accuracy will affect the die cutting accuracy and cause noise. Another example is the elbow bar pressure mechanism and the movable platform to determine the gap is unreasonable, will cause vibration, affect the speed and accuracy.

Second, intermittent institutions, chains and feeding teeth

Flattened Die Cutting Machine to use equal indexing cam mechanism, the shape of the cam is reasonable is a key. Chain tightness to moderate, too tight or too loose will affect the die cutting accuracy. Flat pressure Die Cutting Machine to feed the paper is mostly solid, but in high-speed movement is still easy to deformation, emergency stop inertia. Good teeth high hardness and light weight, angle and pressure the size of moderate.

Third, the transmission system

The current die drive main drive is driven by the motor and the worm gear. Worm gears are mostly helical teeth, it should be noted that when the worm wheel and worm gear in the sub-round, the teeth and teeth between the backlash size is appropriate. The backlash is too large, the worm gear is not smooth; backlash is too small, is not conducive to the flow of lubricants. There is an irrational pressure angle will affect the smoothness of the transmission.

Four, die-cutting version, die-cutting knife and rubber

These three are the basic parts of die-cutting, they are directly related to the quality of die-cutting. Plate requires uniform density, light weight, high hardness, good flexibility, easy processing, smooth, strong, knife line embedded after the stability and can be replaced several times. Knife edge to sharp, the height of the knife and the big knife bending small. Rubber bar hardness should be moderate, can not squeeze the knife-edge, nor can the resilience is insufficient.

Fifth, feeding speed and positioning mechanism

At present, the commonly used method is continuous feeding, that is, the front sheet and the back piece of paper always overlap. This method is smooth, fast, but the rapid movement of the paper on the positioning of the pre-regulation have a great impact, the paper after the force crimping or bounce, resulting in positioning are not allowed. The ideal Die Cutting Machine should ensure that the die cutting speed at the same time, the paper on the feeding platform as low as possible.

Six, chain guide

The role of guide rail in positioning and controlling the chain. The thickness of the guide rail should be suitable and can be embedded in the chain. The distance between the upper and lower rails must ensure that the chain through the smooth, too small to increase the transmission resistance; too large chain easy to beat. The trajectory of the guide rail and the length of the chain also have a certain influence on the performance of the machine.

Seven, pressure institutions

The most important device of the Die Cutting Machine is the pressure-applying mechanism. At present the most common double elbow bar mechanism, the crank rotates one week, it makes the active platform twice to reach the highest limit position. In order to ensure the quality of die cutting, the entire platform should be forced even when pressurized. So the working surface of the upper and lower platforms must be parallel. If the design is unreasonable will cause uneven pressure, empty travel is too large.
