Embodiment Construction
[0057] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0058] A control system for a chain drive tensioner, comprising: an acoustic emission detection unit, a motion control unit, a position detection unit, a comparison unit, a display unit and a PLC control system.
[0059] The acoustic emission detection unit is used to collect the acoustic emission signal produced in the chain transmission process, and transmits the collected signal to the control computer 22; the motion control unit is used to control the tension motor and the brake motor, and then control the brake mechanism 5 and the tension motor. The tightening mechanism 2 starts an...

The invention provides a control system and method for a chain transmission tensioning device. The control system and method are used for controlling the chain transmission tensioning device so as to solve the problem of looseness of a chain in the chain transmission process. The control system specifically comprises an acoustic emission detection unit, a motion control unit, a position detection unit, a comparison unit, a display unit and a PLC system; the acoustic emission detection unit is used for collecting acoustic emission signals generated in the chain transmission process; the motion control unit is used for controlling a tensioning motor and a brake motor; the position detection unit is used for controlling the displacement stroke of a brake mechanism and detecting the rotation angle of a tensioning mechanism; the comparison unit and the display unit are respectively used for comparing and displaying related data; and the PLC system comprises a feedback module, a delay module and an early warning module, and the early warning module is used for estimating the remaining service life of the chain and reminding workers to replace the chain. According to the control system and the control method, the chain transmission tensioning device can be quickly, effectively and accurately controlled, and the problem of looseness of the chain is solved.
Description
technical field [0001] The invention belongs to the field of mechanical transmission control, in particular to a control system and method for a chain transmission tensioning device. Background technique [0002] The chain drive tensioning device is used to solve the problem of chain slack during the chain drive process. The instantaneous speed of the chain drive is unstable and has certain impact, vibration and noise. With long-term work, the chain links will wear to a certain extent, thus As a result, the contact between the chain and the sprocket may fall off, the transmission efficiency is reduced, and even mechanical failures occur. Such problems can be solved to a certain extent by the tensioning device. [0003] At present, most of the tensioning devices used are manually controlled, and the shortcomings of manual control are mainly manual control of the tension degree, which does not have quantification function, and the labor cost is large; while most of the tension...
