Aluminum foil, film, non-woven fabrics and other products need to be cut into fine products of different sizes after printing, so they need to be cut on a slitting machine, and the cutters generally used in the slitting machine are round knives and round pads, which are called Shearing Knives.
Because the knife edge of the slitting machine is precisely made on the outer surface of a circular ring as required, when the upper and lower drums make a circle, 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 that of a pair of scissors. Through the two opposite knife edges 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 cuts aluminum foil, film, non-woven fabrics and other products, the gap between the upper and lower knife edges is large, so the product is not easy to cut, and it can be cut occasionally, and its end face is uneven and the concave and convex surface is obvious. 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, the slitting machine generally adjusts the gap between the knife lines to 0, 20-0, 0.3mm when the cutter is installed before the slitting. Only in this way can the end face of the aluminum foil be guaranteed to be flat, because in the process of aluminum foil slitting, the rebound and impact of the aluminum foil can reduce the metal collision and contact between the upper and lower knife rollers.
From the cross section of the tool, it can be seen that the slitter uses one side of the lower roller knife, thereby improving the mechanical strength of the knife edge. As long as it is used reasonably, the knife edge will rarely collapse.
The above all illustrate the impact of the reasonable installation of the slitting machine blade on the quality. Therefore, when using the slitting machine, in addition to paying attention to correct operation and regular maintenance, the majority of users also need to make reasonable adjustments to the slitting machine blade during operation. Installation and debugging, in this way, not only greatly improves the quality of cutting, but also promotes the rapid development and income of enterprises.
