Difference between automatic die cutting creasing machine price

With the rapid development of printing and packaging products, especially the continuous expansion of electronic products and 5G technology, die cutting creasing machine price is not only limited to the later stage of printing, but also develops into the application of auxiliary materials for industrial electronic products. We should all know that die cutting processing mainly depends on four major parts, die cutting equipment, die cutting die, die cutting material and die cutting process. Die cutting equipment is an important part. Today we will explain in detail about automatic die cutting The seven problems that the machine should pay attention to when die cutting, how to solve these seven problems?

1. The processing quality and assembly accuracy of each component of the equipment

Restricted by the technical level of China’s machinery manufacturing industry, many parts of cheap die cutting creasing machine price have rough processing. For example, the matching and manufacturing accuracy between the intermittent mechanism, the main transmission system and the chain directly affect the machine speed, and if the assembly accuracy is poor, it will affect the die cutting accuracy and cause noise. Another example is the unreasonable determination of the gap between the toggle pressure mechanism and the moving platform, which will cause vibration and affect the speed and accuracy as well as the life of the machine.

2. Intermittent mechanism, chain and paper feeding teeth

The flat die cutting creasing machine price mostly adopts the equal indexing cam mechanism, and whether the shape of the cam is reasonable is the key. The tightness of the chain should be moderate, too tight or too loose will affect the die cutting accuracy. The feeding teeth of the flat die cutting machine are mostly solid, but they are still easy to deform during high speed movement, and the inertia is large during emergency stop. A good tooth row has high hardness and light weight, and the angle and pressure are moderate.

3. Die cutter plate, die cutter and rubber strip

These three items are the basic components of die cutting, and their quality is directly related to the quality of die cutting. The plate material requires uniform density, light weight, high hardness, good flexibility, easy processing, flatness, and firmness. After the knife line is embedded, it is stable and can be replaced many times. The edge of the knife should be sharp, and the height error of the whole knife and the bending of the big knife should be small. The hardness of the rubber strip should be moderate, and it cannot squeeze the edge of the knife, nor can it have insufficient resilience.

4. Paper feeding speed and positioning mechanism

At present, the commonly used method is continuous paper feeding, that is, a part of the front sheet and the back sheet always overlap together. This method is stable and fast, but the rapid movement causes the paper to have a great impact on the positioning front gauge, and the paper curls or bounces after being stressed, resulting in inaccurate positioning. The ideal die cutting creasing machine price should keep the speed of the die cutting while the speed of the paper on the feeding table as low as possible.

5. Diecutting department

The die cutting part is an important device of the die cutting machine. In the current common double toggle structure, the crank rotates once, which enables the movable platform to reach the upper limit position twice. In order to ensure the quality of die cutting, the entire platform should be evenly stressed when pressurized. Therefore, the working surfaces of the upper and lower platforms must be parallel. If the design is unreasonable, the pressure will be uneven and the empty stroke will be too large.

6. Chain guide rail

The guide rail plays a role in positioning and controlling the direction of the chain. The thickness of the guide rail should be suitable, so that it can be embedded in the chain piece. The distance between the upper and lower guide rails must ensure that the chain passes smoothly. If it is too small, it will increase the transmission resistance; if it is too large, the chain will easily jump. The trajectory of the guide rail and the length of the chain also have a certain influence on the performance of the machine.

7. Transmission system

The main drive of the current die cutting machine is driven by the motor to drive the worm and the worm gear. Most of the worm gears are helical teeth. It should be noted that when the worm gear and the worm mesh at the indexing circle, whether the backlash between the gear teeth is appropriate. If the backlash is too large, the worm gear transmission will not be stable; if the backlash is too small, it is not conducive to the flow of lubricating oil. In addition, the unreasonable pressure angle will affect the stability of the transmission.

The above seven problems are not only what buyers need to pay attention to, but also problems that automatic die cutting machine manufacturers need to solve when manufacturing equipment.
