A Tension Control Experimental Platform

Abstract

The present invention relates to a tension control experiment platform. The tension control experiment platform is characterized in that the platform comprises an encoder, an MCGS touch screen, a frame, a power supply and protection device, a tension control board and two winding shaft portions. The two winding shaft portions are of the same structure. The two winding shaft portions and the encoder are arranged in parallel on the upper surface of the frame. The encoder is located between the two winding shaft portions. Each winding shaft portion comprises a main shaft, jackscrew shaft sleeves, a servo motor, a servo amplifier and two acrylic discs; the main shaft passes through the centers of the two acrylic discs; the two acrylic discs are fixed to the main shaft by means of the jackscrew shaft sleeves; two ends of the main shaft are fixed on the frame through corresponding bearings; one end of the main shaft, which is far away from the acrylic discs, is connected with the servo motor through a coupling; a material to be controlled is wound between the two acrylic discs; and the servo amplifier is connected with the servo motor. The tension control board is connected with the MCGS touch screen, the encoder and the two servo amplifiers.

Description

Technical field [0001] The invention relates to the technical field of experiments and teaching devices related to tension control, in particular to a tension control experiment platform. Background technique [0002] Tension control is often used in production equipment such as the packaging industry, metallurgical industry, and new energy industry, and there is an increasing demand for engineers and technicians who master tension control technology. The existing tension control experiment platform is not suitable for colleges and universities to directly use in teaching and student experiments in consideration of safety, developability, price, space and other factors, which affects the training of engineering and technical personnel related to tension control. Therefore, it is necessary to invent an experimental platform that is conducive to the cultivation of the comprehensive technical ability of the learner. It has the characteristics of safety, good developability, reasonab...

AI Technical Summary

Problems solved by technology

Because it uses an AC motor for winding and unwinding control, and there is no corresponding air switch and leakage protection device for safety protection, it may cause danger when students experiment, and it does not involve considerations related to the human-machine interface, which is not conducive to students' comprehensive technical ability cultivation

[0004] The Chinese patent with the patent number ZL201010557995.3 discloses a tension and deviation correction experimental device. The experimental device includes a deviation correction controller, which mainly solves the problem that the material belt guide cannot be controlled. The disadvantage is that the magnetic powder brake is used as the braking device. The magnetic powder needs to be replaced regularly, which makes maintenance inconvenient. Compared with the servo motor, the magnetic powder brake has disadvantages such as poor reliability, short life, easy to generate heat, and the need to replace the magnetic powder regularly.

[0005] Patent No. ZL201010221833.2 discloses a tension control device. There is a stepless reducer and a precision reducer between the motor and the rubber roller. Industrial requirements, but it is difficult to use and maintain when applied to teaching, and it is difficult to cultivate students' ability to control system software development and human-machine interface development
