Opis:
Belt conveyors are commonly employed in manufacturing and excavation processes. One of the basic components of such equipment are flat transport belts which can be monolithic or composite. In both cases, the belts are most often made of plastic materials. The manufacturing process of flat transport belts usually involves two stages. During the first stage, belts of very high length of up to several hundred meters are manufactured with use of the correct technology for a given belt type. In order to be usable in the finished conveyor system, correct length of such belts is to be achieved. Considering the above, the subsequent stage of manufacturing requires cutting the belts down to the appropriate length and very often joining the ends to form a closed loop with specific circumference. In an attempt to answer the demand of the manufacturing industry, the authors took up design works on an automated device for crosswise cutting of monolithic and composite belts. This article presents three construc-tion concepts of the authors’ own design together with an analysis of construction and operating factors which affect their usability. The presented discussion leads to selecting one of the solutions for which a drive system concept designed by the authors is proposed. Additionally, an analysis of the influence of the cutting knife geometry on cutting force is provided.

Opis:
This paper reports experimental research of torques during paperboard cutting in the die cutting press with the screw–nut transmission in the drive mechanism of the movable pressure plate. The purpose of the study is to substantiate the practical implementa-tion of the pressure plate drive mechanism with the use of screw–nut transmission for the production of cartons of paperboard blanks. The manufactured experimental bench for the research of paperboard blanks provides the possibility of getting dependencies of loads on different parameters of the die cutting process. The developed method of the experimental research envisages the use of the strain gauge method and the wireless module for data measurement and software for its processing that allow getting trustworthy results with minimum faults. As a result of experimental research studies, the impact of paperboard thickness and cutting velocity on torque values has been established. Results of experimental research allow getting trustworthy and systematised information about torque values depending on the thickness of the paperboard, the paperboard fibre direction and pressure plate displacement velocity. It is established that torque values on drive shaft during die cutting of paperboard blanks made of folding boxboard with thickness that lay in range of 0.3–0.7 mm. Experimental research studies show the impact of rotation speed of a drive shaft of the pressure plate drive mechanism on the torque value. The article shows the workability of the designed device with screw–nut transmission in the drive mechanism of a movable pressure plate.
