As an improvement of the present invention, a guiding thread roller is provided on the inner frame wall of the cradle frame corresponding to the shaft hole of the threading shaft.

As an improvement of the present invention, the transmission gear set includes a large gear and a pinion, the large gear is set on the pay-off shaft, the pinion is set on the permanent magnet damping adjuster, and is connected to the large gear The gears mesh.

As an improvement of the present invention, the threading shaft is longer than the rotating shaft.

The beneficial effects of the present invention are: the present invention is ingenious and reasonable in design, adopts passive pay-off, can adjust the pay-off speed through the permanent magnet damping regulator, thereby realizing tension control, and is set on the cradle of the stranding machine through the rotating shaft On the shelf, it can be shaken freely to realize back-twisting pay-off, which makes the pay-off action more natural and smooth, greatly improves the pay-off effect, and has a good twisting effect, which effectively guarantees product quality, and is easy and convenient to operate, saving time and effort, and effective It greatly saves a lot of time and manpower, greatly improves work efficiency, reduces production costs, and is conducive to widespread popularization and application.

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

detailed description

Referring to Fig. 1, a cradle-type tension pay-off device provided in this embodiment includes a threading shaft 1, a rotating shaft 2, a cradle frame 3, a pay-off shaft 4, a permanent magnet damping adjuster 5 and a transmission gear set 6 , the pay-off shaft 4 is connected and arranged in the cradle frame 3, the permanent magnet damping adjuster 5 is arranged on the cradle frame 3, and communicates with the pay-off shaft 4 through the transmission gear set 6 connected, the threading shaft 1 is set at one end of the cradle frame 3, and is perpendicular to the central axis of the pay-off shaft 4, and the rotating shaft 2 is set at the other end of the cradle frame 3, and is connected to the The threading shaft 1 is on the same axis.

Preferably, a guiding thread roller 7 is provided on the inner frame wall of the cradle frame 3 corresponding to the shaft hole of the threading shaft 1, so that the effect of the wire is good.

Specifically, the transmission gear set 6 includes a bull gear and a pinion, the bull gear is set on the pay-off shaft 4, the pinion is set on the permanent magnet damping adjuster 5, and is in phase with the bull gear engage.

Preferably, the length of the threading shaft 1 is longer than that of the rotating shaft 2, which is more convenient for installation and rotation, and has a better effect of threading.

During installation, the cradle type tension wire releasing device of the present invention is evenly arranged on the peripheral position of the cradle frame 7 of the stranding machine. Axle 74, two fixed disks 72 are arranged on the main shaft 75 at intervals, a plurality of tension pay-off devices are movably arranged between the two fixed disks 72 through bearing assemblies, and the moving ring 71 is eccentrically arranged on one of the fixed disks 72. In the side position, one end of the yaw arm 73 is movably arranged on the moving ring 71, and the other end is connected with one end of the corresponding rotating shaft 2 or threading shaft 1, and one end of the yaw wheel shaft 74 is arranged on the frame, The other end stretches into the inner ring of the moving ring 71 and is provided with a pulley that can press against the inner ring wall of the moving ring 71 .
