Wire feeding mechanism, and six-head type constant-tension wire feeding device with wire feeding mechanism

Abstract

The invention relates to the technical field of wire feeding mechanisms, in particular to a wire feeding mechanism which comprises a support, a lifting table, a drive motor, an air cylinder, a movabletip cone, a fixed tip cone, a swing arm mechanism, a balancing weight block, a wire leading guide wheel group, a despooling seat and a feedback system. According to the wire feeding mechanism provided by the invention, the balancing weight block is adopted for adjusting the despooling tension of the swing arm mechanism, and the feedback system can be used for adjusting the rotating speed of the drive motor, so that a swing arm of the swing arm mechanism and the balancing weight block keep relative balance, so that the despooling tension is constant. The fixed tip cone drives the despooling seat to despoil, the movable tip cone can be used for fixing wire axes with different sizes into the despooling seat, and the despooling seat and the swing arm mechanism are staggered at the up and downposition, so that the vertical space is fully used. The invention provides a six-head type constant-tension wire feeding device with the wire feeding mechanism. Six wire feeding mechanisms are integrated into an overall machine table, and the wire feeding angles of the wire feeding mechanisms are staggered by utilizing wire collecting guide wheel groups, so that the vertical space is fully utilized.

Description

technical field [0001] The invention relates to the technical field of wire feeding devices, in particular to a wire feeding mechanism and a six-head constant tension wire feeding device with the wire feeding mechanism. Background technique [0002] Most of the multi-head pay-off devices used at present adopt multiple independent pay-off racks in the layout of the machine, which are simply placed and fixed on the ground according to the production requirements. The overall structural composition has certain flexibility and low manufacturing cost, but the stability, integrity and operability of the entire cabling system are poor, and it is only suitable for loading smaller sized bobbins, and it is not conducive to the later production line.

[0002] Most of the multi-head pay-off devices used at present adopt multiple independent pay-off racks in the layout of the machine, which are simply placed and fixed on the ground according to the production requirements. The overall structural composition has certain flexibility and low manufacturing cost, but the stability, integrity and operability of the entire cabling system are poor, and it is only suitable for loading smaller sized bobbins, and it is not conducive to the later production line. Renovation and reorganization, the overall structure is fragmented and the land area is large

At the same time, the single-spring tension gun and cowhide belt are mostly used to control the tension of the single pay-off stand, which is a purely mechanical tension control method. The stability and accuracy of each control method are not high, resulting in poor final cable quality.
