Active pay-off machine device

Abstract

The invention discloses an active paying-off machine apparatus, which comprises a frame, wherein, rotational fast pulleys are fixed at the upper part of the frame; brackets, which are fixedly connected with the frame, are respectively arranged on two sides of the fast pulleys; cable clamps are fixed on the brackets; a rotating shaft is connected with an end part of a rocker arm, the rotating shaft is rotationally matched with bearings arranged on the frame; driving wheels, which are connected with the fast pulleys through an inner core of a wire cable, are rotationally fixed at one end of the rocker arm away from the rotating shaft; and the rotating shaft is connected with the twist spindle of a sensor used for sensing the rotation angle. The active paying-off machine is used for controlling the paying-off speed of the active paying-off machine, thereby balancing the tension of the inner cores of the wire cable arranged between the active paying-off machine and a plastic extruder within a certain range, improving the paying-off speed, and reducing the fault rate of the inner core of the wire cable.

Description

technical field [0001] The invention relates to an active pay-off device for a pay-off machine, in particular to an active pay-off device for adjusting cable tension between a pay-off machine and an extruder. Background technique [0002] In the extruded single-wire production of communication cables, the inner core of the communication cable is coiled on the coil of the pay-off machine. The wire end of the cable inner core is pulled by the end of the extruder, passes through the extruder, and puts an insulating jacket on the cable inner core. [0003] In the existing extrusion single-line production, the pay-off machine is generally passive. The inner core of the cable coiled on the spool is only subjected to the pulling force of the extruder end, and through extrusion, the spool is driven to rotate at the same time. The diameter of the communication cable is small, and the reel of the pay-off machine has a large rotational friction, which tends to stretch the inner core ...

AI Technical Summary

Problems solved by technology

Due to the gravity effect of the moving wheel and the slider during the induction process, the tension of the inner core of the wound cable will be increased, and when adjusting the reel speed, the influence of the gravity of the moving wheel and the slider needs to be considered, and the adjustment of the equipment is more troublesome.

The potential is changed by sliding the moving wheel up and down on the screw rod composed of the potentiometer shaft. The moving wheel needs a large displacement to make the potentiometer respond accurately, so this sensing method is not sensitive.
