Untwisting pay-off device

Abstract

The invention relates to a twist-back pay-off device, which includes a frame, a dial for fixing the pay-off wheel is installed on the frame, the dial drives the pay-off wheel to rotate and pay off, and a plurality of wire passing wheels are fixed on the frame, and the pay-off The core wire on the wheel bypasses the thread-passing wheel for output, and a hollow shaft is installed coaxially with the dial on the frame, the hollow shaft is hollow, and two parallel thread-passing wheels are movable and fixed on the top. The dial is installed in the middle of the frame, and the dial is connected to the motor through a transmission mechanism. A core wire surrounding column is fixed on the frame, and the core wire on the pay-off wheel first bypasses the core wire surrounding column and then other wire passing wheels for output. A column is fixed on the frame, and a cable pulley is movably fixed on the column. An adjusting nut is also arranged on the hollow shaft. The invention can greatly improve the quality of electronic wire products and is suitable for popularization and application.

Description

Technical field: [0001] The invention relates to the technical field of electronic wire production equipment, in particular to an untwisting and untwisting pay-off device used on a winding machine and a stranding machine. Background technique: [0002] With the development of science and technology, shielded wires that can protect the electrical signals flowing through the inner core copper wires from the interference of external electromagnetic fields have been widely used in the national economy and people's livelihood. During the production process, the shielded wire is easily twisted when it is unwound, which affects the quality. The patent document with the publication number CN1088244C discloses an ultra-high-speed core wire winding machine. The winding machine is divided into a pay-off device and a take-up device. The machine hardly vibrates, but its pay-off device also has a little flaw. figure 1 Shown is the schematic diagram of the pay-off device of the winding m...

During the production process, the shielded wire is easily twisted when it is unwound, which affects the quality

The patent document with the publication number CN1088244C discloses an ultra-high-speed core wire winding machine. The winding machine is divided into a pay-off device and a take-up device. The machine hardly vibrates, but its pay-off device also has a little defect

figure 1 Shown is the schematic diagram of the pay-off device of the winding machine, which includes a frame 01 and a pay-off wheel 02 suspended on the frame 01. The defect of this structure is that the pay-off wheel 02 rotates and pays off the wire. In the middle, the center of gravity of the pay-off wheel 02 will move left and right accordingly, and the rotation center and center of gravity of the pay-off wheel 02 are not on the same vertical line, so that the speed of the pay-off wheel 02 is unstable, and the instability of the pay-off wheel 02 makes the core When the thread is in various positions, the tension is not stable, and it is even easy to break the core thread
