Though above-mentioned pre-soaking fiber textile board molding mode extensively is employed, and so still exists many shortcomings, such as:

1. its program is rather complicated, and required device accessory is a lot of, account for than large space, thus the utilized space of reducing factory building, thus overall economic efficiency reduced.

2. because fiber weavening plate is wound on the spool from level to level, when treating to cut, must spread board fiber board out as cloth, and cut into a piece parallelogram by appropriate size, folded again, so just exist to be wound into whole volume, spread out the shortcoming of heavily covering operation that cuts again.

From the above, existing fiber weavening plate molding mode reaches more greatly because of taking up space that operation is numerous to be covered, and causes inefficiency to diminish economic benefit, demands urgently improving.

Main purpose of the present utility model is to improving the operation shortcoming of above-mentioned present stage, and a kind of volume yarn machine of making carbon fibre racket frame is provided, and can reduce institute and take up space, by adopting the link-up operation mode to increase work efficiency.

The utility model is for achieving the above object made the volume yarn machine of carbon fibre racket frame, refers in particular to a kind of fiber ribbon of reeling to make the spool of racquet frame, finishes the fiber ribbon that rolls and then can form fiber weavening plate, it is characterized in that:

The spool two ends are set up on the frame, establish a guide screw in frame one side-lower, guide rail and tooth bar are then established in the top, other establishes a movably pre-bath unit, establish one in the bracing frame below of this pre-bath unit and revolve the swivel nut of being located at guide screw, then be provided with and guide rail in the bracing frame stage casing, the guide groove that tooth bar cooperates, follower, establish a preimpregnation bucket in the bracing frame top in addition, preimpregnation bucket inside be provided with across the guide rod group, establish one group of rotating cantilever in preimpregnation bucket both sides in addition, cantilever the place ahead is established and is established one rotationally and can suppress in the pinch roller of spool circumferential surface

The length of spool is about the length of three fiber weavening plates, and the circumference of spool is to make the required length of racquet frame.

Advantage of the present utility model is: 1. its work programme is simple, and required mechanism's number is less, and volume is less, so can increase the space that utilizes of factory building.

2. because fiber weavening plate can be directly by delineating angle on the spool in advance, fold under directly cutting out, and need be by existing manufacture, being rolled into a big volume earlier spreads out and cuts into a fiber weavening plate that piece is required, so the utility model not requirement is surveyed, high and the energy link-up operation of its operating efficiency is suitable for Quantity production.

Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing.
