Abstract: Purpose.Development and design of an electric drive for a cutting machine that allows for the separation of three-layer corrugated cardboard into individual sheets with an automated process of transporting the material along a conveyor line in accordance with production needs.Method.As part of the research, the method of complex modeling was used to build 3D models of the structure of the electric drive mechanism of a blade of the cutting machine and all the executive equipment to be used in its composition; the method of empirical description of technological processes for the justification and explanation of the peculiarities of the organization of the transmission of torques during the operation of the drive; the method of conducting an experiment to certify the functional capabilities of the product. Results.Based on the use of the necessary equipment in the composition of: an electric motor, a gear mechanism, an electromagnet, magnetic starters, a transformer, light-signal fittings, electrical protection and control devices and the proposed 3D model of the structure, an electric drive of a cutting machine was developed in accordance with the proposed kinematic scheme.The functioning of the electric drive mechanism for the movement of the cutting rectilinear blade of the machine is ensured by the use of an asynchronous electric motor with a squirrel-cage rotor, which, in comparison with brushless DC motors, has advantages in simplicity, reliability, economy and durability.Scientific novelty.The methodology for increasing the efficiency of automated cutting of sheet blanks on a production conveyor line was further developed by implementing the developed cutting machine with an electric blade movement mechanism, which contributes to improving the quality of the work performed.The electric drive of the cutting machine for an automated conveyor line was theoretically substantiated and developed, which, when cutting sheet loads, drives the rotating parts of the product structure while maintaining the conveyor belt speed of 1,3 m/s.The control of the electric drive of the product is implemented on the basis of: an electric motor, a gear mechanism, an electromagnet, magnetic starters, a transformer, light-signal fittings, electrical protection and control devices.Practical importance.The developed electric drive of the cutting machine is designed for separating three-layer corrugated cardboard into separate sheets with an automated process of transporting the material along a conveyor line in accordance with production needs.A distinctive feature of the development is the implementation of an electric drive mechanism for the blade movement according to the proposed kinematic scheme.The main advantage of using the product is that at the time of cutting, pressure on the material being cut is not applied along the entire length of the cut and the applied cutting force is not reduced.The use of an electric drive cutting machine for an automated conveyor line involves performing cyclic operations both in remote and automatic mode, providing a cutting force of 224 N. The blade inclination angle is 2° and provides the separation of three-layer corrugated cardboard blanks measuring 2000×1300 mm and 4 mm thick.The adopted technical solutions are capable of fully ensuring the automated operation of the production conveyor line.
