Embodiment Construction

[0011] The technical solution of the present invention will be further detailed below in conjunction with the accompanying drawings and embodiments:

[0012] As shown in the accompanying drawings, the supporting device for prepreg tow bobbins in the automatic fiber placement process is characterized in that: the device includes a fixed mandrel 1, which is fixedly installed on the automatic fiber placement machine In the yarn box, the primary rotating shaft 4 is mounted on the fixed mandrel 1 through primary bearings 3 at both ends, the primary bearings 3 at both ends are positioned through the bearing circlip 2, and the yarn bobbin fixing sleeve 5 is mounted on a secondary bearing 6 On the left end of the primary rotating shaft 4, one end of the prepreg tow bobbin 9 is sleeved on the bobbin fixing sleeve 5. When the prepreg tow bobbin 9 rotates, the bobbin fixing sleeve 5 is driven to rotate, and the flat spiral spring 8 is wound Between the bobbin fixing sleeve 5 and the primary...

Abstract

The invention relates to a supporting device of a pre-impregnated silk flock yarn barrel for an automatic fiber laying process. The device mainly comprises a fixed core shaft, a first-stage rotating shaft, a volute spiral spring, a fixing device, a yarn barrel fixing sleeve and a tension adjusting mechanism. The device is mainly used for providing necessary support for the pre-impregnated silk flock yarn barrel, so that the yarn barrel can rotate while silk flocks are unwound in the automatic silk flock laying process, and the conveying resistance of silk laying equipment is reduced; and the device can also be used for providing quantification controllable resilience tension, so that the tension of the pre-impregnated silk flocks can be quantitatively controlled in the automatic silk flock laying process, and the aim of adjusting the conveying tension in the pre-impregnated silk flock unwinding process is fulfilled. By the device, the conventional pre-impregnated silk flock supporting mechanism is greatly optimized, and the automatic laying efficiency of the silk flocks is greatly improved; and the device has a simple structure, is convenient to operate and can be widely applied in the field of relative processes such as an automatic silk laying process, an automatic belt laying process and a winding process.

Description

Technical field [0001] The invention is a support device for prepreg tow bobbins in an automatic fiber placement process, and belongs to the technical field of product structure. The supporting device is mainly used in automatic placement equipment for composite materials. Background technique [0002] In the automatic tow placement process, the raw material used is mainly the prepreg tow after slitting, which is usually in a cylindrical shape. To ensure stable tow delivery during the automatic tow placement process, it is very important to maintain a stable tension. The tow tension has an important influence on the mechanical properties of composite parts. At present, the automatic silk laying equipment is relatively mature abroad, but the related technical blockade is more serious. Domestic automatic tow placement equipment has no mature products for the time being. The current automatic tow placement equipment prototype bobbin support device has a complicated structure, whic...
