Experimental research on the process of cutting transport belts

Abstract

The work presents the construction of a device designed to perform the cross-cutting process of conveyor belts. The device is equipped, among others, with a pneumatic drive in the form of a double acting piston rod. This actuator ensures reciprocating movement of the knife. The paper also presents the results of the pressure changes in the working chambers of the actuator as a function of displacement, recorded during the working movement of the knife which it performs during the cutting process. The tests were carried out in order to assess the level of pressures in the cylinder chambers during the cutting of belts of various constructions. These values were converted into cutting force values. It is important from the point of evaluation of changes in the value of cutting force of belts characterized by a different internal structure (composite belts made of different materials) and total thickness.
