Slitting accuracy and speed are important indicators to evaluate the performance of slitting machine, the following is a detailed introduction to these two concepts:
1. Slitting accuracy
Slitting accuracy refers to the level of accuracy of the slitting machine when performing the slitting operation, usually in millimeters (mm). It is affected by a variety of factors, such as the accuracy of the cutter, the accuracy of the transmission system, the hardness of the rubber on the surface of the feeding roller, and the pressure setting of the feeding roller. The specific influencing factors are as follows:
• Cutter and drive system: The transmission accuracy of the feeding roller and cutter roller, as well as the quality of the round knife or the grinding of the knife edge on the cutter, will affect the slitting accuracy. If the quality of the cutter is poor or the grinding of the blade is not standardized, it is easy to cause problems such as burrs and uneven paper arrangement.
• Paper Feeding Roller: The hardness of the rubber on the surface of the paper feeding roller and the pressure setting of the paper feeding roller do not meet the requirements, which will affect the slitting accuracy and cutting quality. If the pressure of the paper feeding roller is too small, it is easy to cause insufficient traction, and the conveyed paper sheet slips on the paper feeding roller, which affects the paper cutting accuracy; If the pressure is too high and exceeds the elasticity of the rubber roller surface, it will cause wrinkles in the paper web and will also affect the quality of the paper cut.
• Paper sorting parts: If the air hammer, air blowing pipe, horizontal beating plate, and longitudinal beating baffle of the paper sorting part do not meet the specified requirements, it will cause uneven paper arrangement, and then affect the cutting quality.
2. The slitting speed
Slitting speed refers to the length that a slitter machine is able to slitting per minute, usually in meters per minute (m/min). The selection of slitting speed needs to take into account the production needs and the characteristics of the material. For production lines with higher speed requirements, it is necessary to choose equipment with faster slitting speed.
In practical applications, slitting accuracy and speed are interrelated. In pursuit of high speeds, it is necessary to ensure that the slitting accuracy is not compromised. Therefore, when choosing a slitting machine, these two factors need to be considered comprehensively to meet the production needs.
In addition, the maintenance and maintenance of the slitting machine is also an important factor to ensure the stability of slitting accuracy and speed. Regular inspection, cleaning and maintenance of equipment can extend the service life of equipment and improve production efficiency. At the same time, professional training for operators to improve operating skills and safety awareness is also the key to ensure the normal operation and efficient production of equipment.
