Aluminum foil, film, non-woven fabric and other products need to be cut into fine products of different specifications and sizes after printing, so they need to be cut on a slitter, and the cutters generally used in the slitter are round knives and round pads, which are called Shear cutter.
Since the knife edge of the slitting machine is precisely processed on the outer surface of a circular ring according to the requirements, when the upper and lower rollers rotate once, the slitting knife line will work once. For each knife point of the slitting machine, Participate in the contact of the tangent line under the rotation of the knife.
In fact, the working principle of the slitting machine is similar to a pair of scissors. Through the two relative blades of the upper and lower rollers, the slitting effect of aluminum foil, film, non-woven fabrics and other products is realized.
When the slitting machine slits aluminum foil, film, non-woven fabrics and other products, the gap between the upper and lower knife edges is large, and the product is not easy to cut, and occasionally it can be cut, and its end surface is uneven and concave-convex. However, the gap between the upper and lower knife edges is small, and longitudinal textures will appear on the surface of aluminum foil, film, non-woven fabrics and other products.
In addition, when the slitting machine is generally installed with knives before slitting, the gap between the knife lines is adjusted to 0, 20-0, 0.3mm. Only in this way can the end face of the aluminum foil be guaranteed to be flat, because during the aluminum foil slitting process, the rebound and impact of the aluminum foil can reduce the metal collision and contact of the upper and lower knife rollers.
From the section of the cutter, it can be seen that the slitting machine uses one side of the lower roller cutter, thereby improving the mechanical strength of the cutter edge. As long as it is used reasonably, the cutter edge will rarely collapse.
All of the above have explained the impact of the reasonable installation of the slitting machine blade on the quality. Therefore, when the majority of users use the slitting machine, in addition to paying attention to correct operation and regular maintenance, they also need to properly control the slitting machine blade during operation. Installation and commissioning, in this way, not only greatly improves the cutting quality, but also promotes the rapid development and income of the enterprise.
