Composite material uncoiling centering adjustment device with damping function

Abstract

The invention discloses a composite material uncoiling centering adjustment device with a damping function. A rotating central spindle is mounted on an uncoiling support through a pair of deep groove ball bearings in a double-bearing bearing seat. The rotating central spindle is provided with a centering shaft sleeve and a centering adjusting central shaft which are concentric, the centering shaft sleeve and the centering adjusting central shaft are provided with conical faces which are the same, and the distance of the centering shaft sleeve and the centering adjusting central shaft is adjustable, so that a coiling block and the rotating central spindle are concentrically fixed. The other end of the rotating central spindle is provided with a friction drum which is provided with a damping belt in a winding mode, one end of the damping belt is fixedly connected with the uncoiling support, and the other end of the damping belt is connected with a hook head of an adjusting hook. The cylinder end of the adjusting hook is connected to a damping support through an adjusting spring and an adjusting nut, and the tension of uncoiling can be changed by adjusting the adjusting nut. A rotating detecting piece is fixed on the end face of a friction wheel, the detecting end of a proximity sensor directly faces the extending end of the proximity sensor, and whether composite materials are broken is judged by detecting variation of received signals. The composite material uncoiling centering adjustment device has the advantages of being suitable for composite material coiling blocks of different specifications and adjustable in tension in the uncoiling process, and having the function of detecting breakage.

Description

technical field [0001] The invention relates to a composite material unwinding device with a damping function, specifically, it is a kind of unwinding device that can adapt to the difference in the inner diameter and length of the composite material reel, and can adjust and fix the center. Tension adjustment and break detection function. Background technique [0002] Composite winding molding has become one of the important processing technologies of composite materials. It has been widely used in the high-tech fields of national defense construction and gradually extended to civilian industries. Maintaining the tension stability of the composite material during the winding process is an important indicator to determine the performance of the winding equipment. The unwinding device of the winding equipment enables the composite material to be continuously transported to the subsequent processing device. The coaxiality of the rotating mandrel of the unwinding device and the...

Problems solved by technology

[0003] The current unwinding device is usually only suitable for composite yarn rolls of specific specifications, or different centering sleeves need to be replaced according to different specifications of raw materials. The adaptability is not strong and the centering effect is poor, which makes the unwinding tension change greatly. , without tension adjustment function or with high cost and complex control torque motor or electrorheological fluid damper for tension control, and the unwinding device usually does not have the function of detecting the fracture of composite materials
