In the papermaking industry, roll paper cutting machines are an essential equipment. It can cut the entire paper roll according to the preset size, ensuring the flatness and dimensional accuracy of each paper roll. However, some users may encounter a problem where they find the cutting surface uneven after cutting the entire roll. This may affect the effectiveness and production quality of subsequent paper rolls. So, how to ensure the flatness of the cut surface of the entire roll cut by the raw paper cutting machine? Now let’s introduce it to everyone.
1) Choose the appropriate cutting blade: The cutting blade is one of the core components of the raw paper cutting machine, and its quality directly affects the cutting effect. Therefore, it is necessary to choose high-quality cutting blades to ensure their sharpness and accuracy. At the same time, it is also important to pay attention to the wear of the blades and replace severely worn blades in a timely manner.
2) Adjusting cutting parameters: During the use of the raw paper cutting machine, cutting parameters need to be adjusted according to different paper types and thicknesses. Generally speaking, for thinner paper, it is necessary to slow down the cutting speed to avoid shaking or vibration during the cutting process; For thicker paper, it is necessary to increase the cutting speed appropriately to ensure cutting accuracy and flatness.
3) Keep the machine clean: The original paper cutting machine needs to be kept clean during use. Especially in the area around the cutting blade, there should be no dust or debris. Otherwise, these impurities will affect the sharpness and accuracy of the blade, resulting in poor cutting effect.
4) Adjusting the air pressure: In the raw paper cutting machine, the air pressure is also an important factor affecting the cutting effect. If the air pressure is unstable or insufficient, it can cause shaking or vibration during the cutting process, thereby affecting the flatness of the cutting. Therefore, it is necessary to adjust the air pressure according to the actual situation to ensure stable and sufficient air pressure.
5) Adjusting the drum pressure: In the raw paper cutting machine, the drum pressure is also an important factor affecting the cutting effect. If the drum pressure is too high or too low, it can cause deformation or vibration of the paper during the cutting process, thereby affecting the cutting smoothness. Therefore, it is necessary to adjust the drum pressure according to the actual situation to ensure that the pressure is moderate and stable.
6) Regular maintenance: During the use of the raw paper cutting machine, regular maintenance is required. This includes checking the wear of the blades, adjusting the air pressure, and checking the lubrication of the transmission part. These measures can ensure the normal operation of the machine, thereby improving the cutting effect and production quality.
In short, to ensure the flatness of the cut surface of the entire roll of the raw paper cutting machine, multiple aspects need to be taken into consideration. This includes measures such as selecting suitable cutting blades, adjusting cutting parameters, maintaining machine cleanliness, adjusting air pressure, adjusting drum pressure, and regular maintenance. Only when these measures are implemented and implemented can cutting flatness and production quality be guaranteed.
