Abstract

The invention discloses a splicer tension control system comprising a control unit, a cylinder, an ultrasonic detecting device and a pneumatic brake. The ultrasonic detecting device and the pneumatic brake are electronically connected with the control unit respectively. The cylinder and the pneumatic brake are connected to an air source respectively. A pressure-regulating overflow valve is arranged on an air way between the cylinder and the air source, and a proportional pressure valve is arranged on another air way between the pneumatic brake and the air source and is connected with the control unit. A piston position detecting unit used for detecting the position of the piston is arranged in the cylinder and is connected with the control unit. Tension stability of the tension control system of the splicer is good, probability of overshoots and tension shocks is reduced; and in the movement range of the tension cylinder, by the aid of the splicer, the set pressure can be maintained constantly, and the constant tension of paper can be maintained.

Description

technical field [0001] The invention belongs to the technical field of paper splicers, and in particular relates to a tension control system of a paper splicer. Background technique [0002] At present, there are many kinds of tension control systems for paper splicers in the market, some of which are selected through the selection of large, medium and small coil diameters and fuzzy calculation of tension setting values, and some are equipped with tension feedback devices, and the tension control is realized through PID calculation according to the tension feedback value. and many more. With the increasing requirements of customers and the increasing types of air pressure brakes, these methods have exposed many disadvantages: Some tension control methods are only suitable for one type of brake. If there is a change, there may be problems; some tension control methods cannot guarantee a constant tension system, requiring operators to continuously adjust the tension during th...
