Problems solved by technology

In the stranding process, mechanical friction or electrical setting parameters are usually used to control the tension of a single wire conductor. The disadvantage is that during the operation of the equipment, as the wire conductors stored in the pay-off reel change from a full reel to a shallow reel , the tension cannot be detected in real time and the stability of the pay-off tension of the wire conductor in the reel can be adjusted, which may easily cause wire breakage during the stranding process and the finished product after stranding is not smooth, arched, and easy to loose, and sometimes the cable conductor line Core DC resistance unqualified and other quality defects
If it is not dealt with or improved in time, it will seriously affect the safe operation of the cable
With the rapid development of power cables in my country, the quality requirements for large-section conductive core products have been improved, and strict requirements are required for the release tension of the conductive core to be uniform and stable. The traditional outlet tension device has been unable to meet the equipment requirements.

Abstract

The invention relates to a tension detection control device for a center-based stranding machine, comprising a pay-off spool (1). A cable core (2) is twined and connected on the pay-off spool, a range sensor (5) that is in induction fit with the cable core is arranged below the pay-off spool, one side of the pay-off spool is provided with a brake (7), a proportional pressure valve (8) and a solenoid valve (9) which are mounted through a brake support (6) and connected by a pipeline, and the solenoid valve is connected with an air source (12) through a third pipeline (12); and the tension detection control device further comprises a control device (14) connected with the range sensor and the solenoid valve. The tension detection control device has the advantages that the device is used for detecting the match degree of the change, from a full plate to a shallow plate, of a wire conductor stored in the pay-off spool and the line outgoing speed of a complete machine, matches up with an air pressure disc brake through an inductor detection feedback mode in the process of releasing the conductive cable core, and automatically adjusts the stability of line releasing tension of the wire conductor stored in the pay-off spool, so that the cable releasing tension is guaranteed to be uniform and stable, and the cable stranding quality is improved.

Description

technical field [0001] The invention relates to the technical field of component parts of a stranding machine, in particular to a tension detection control device for a central stranding machine. Background technique [0002] In the process of twisting a plurality of copper wires or aluminum single wires with smaller diameters into larger cross-section conductive cores according to certain rules by using a central twisting machine, according to the requirements of the twisting process, the number of different coils can be placed on the stranding body. Use in any combination. In the stranding process, mechanical friction or electrical setting parameters are usually used to control the tension of a single wire conductor. The disadvantage is that during the operation of the equipment, as the wire conductors stored in the pay-off reel change from a full reel to a shallow reel , the tension cannot be detected in real time and the stability of the pay-off tension of the wire cond...
