The spool bearing seat is movably installed on the upper end of the spool support plate, and the lower part of the spool support plate is centrally welded to the spool support plate to increase the mechanical strength.

The main working steps and principles are:

The operator lowers the 4 supporting feet, pushes the mobile handle to move the pay-off frame to the designated production line, lifts the 4 supporting feet out (higher than the moving wheel set), and then removes the tearing rope that needs to be paid off. The coil (or other coils) is installed on the support cylinder of the pay-off assembly (fixed by the support cylinder shrapnel), and then the tension meter is used to calibrate whether the tension of the pay-off meets the process requirements, and the tension can be changed by adjusting the tension adjusting nut (permanent permanent magnet). The larger the distance between the fixed piece and the moving piece, the smaller the tension, and the smaller the distance between the two, the greater the tension), and then install the spare tearing ropes on the 6 support cylinders of the spare spool assembly (through the support cylinders). The shrapnel is fixed, stable and reliable), and then the tearing rope can be inserted into the die core of the machine head according to the process requirements;

During the work, the permanent magnet tensioner uses the principle of magnetic attraction to provide the pay-off tension stably (accuracy can reach ±0.5N), and the tight support cylinder shrapnel of the tearing rope coil in the pay-off assembly is fixed in the corresponding groove of the support cylinder It is used to ensure the synchronous rotation of the tearing rope and the supporting cylinder.
