Abstract

The utility model discloses a drying device for starched carbon fiber. The drying device comprises a drying cavity, wherein an inlet and an outlet are respectively arranged at two ends of the drying cavity. Carbon fiber tows get in or out from the inlet or the outlet, and pass through the drying cavity. The drying cavity is communicated with a hot wind source and the hot wind heats and dries the carbon fiber tows in the drying cavity. A furnace end heat roller and a pressing heat roller are arranged on the inlet, and the carbon fiber tows are wound on the furnace end heat roller. The pressing heat roller is close to the furnace end heat roller and squeezes the carbon fiber tows. The drying cavity is in corrugated shape, and the hot wind curvedly goes forward in drying cavity, and passes through the carbon fiber tows repeatedly and sufficiently heats and dries the carbon fiber tows. The furnace end heat roller and the pressing heat roller are arranged on the inlet of the drying cavity, and squeeze the starched carbon fiber tows and water in the carbon fiber tows is squeezed out, so the carbon fiber tows can be rapidly dried in the drying cavity, and moreover, the squeezing enables the surface of the carbon fiber tows to be smooth, and enables the fibers in the tows to be tidily arranged, and strengthens integral strength of the tows.

Description

Drying device after the carbon fiber starching

Technical field

The utility model relates to the carbon fiber manufacturing technology, relates in particular to a kind of to the withering device of the carbon fiber after the starching.

Background technology

The carbon fiber starching needs that later on it is carried out drying to be processed, and drying device commonly used is to adopt hot blast that carbon fibre tow is heated, so that the intrafascicular water evaporates of carbon fiber wire, and is taken away by hot blast, reaches the dry purpose of processing.This drying mode is from outside to inside, and the moisture content on tow surface at first evaporates, but the moisture content of carbon fibre tow inside but is difficult to quick removal, therefore, is necessary the Drying Treatment Technology of carbon fiber after the starching is improved.

The utility model content

The purpose of this utility model provides drying device after a kind of carbon fiber starching, conveniently carbon fibre tow after the starching is carried out drying processes, and shortens the dry processing time, the raising drying effect.

The utility model is that the technical scheme that its technical problem of solution adopts is,

Drying device after the carbon fiber starching, include drying chamber, described drying chamber two ends have import and outlet, and carbon fibre tow passes in drying chamber from import and outlet turnover, drying chamber is communicated with hot air source, hot blast to the carbon fibre tow in the drying chamber heat, drying, described porch is provided with stove end hot-rolling and compresses hot-rolling, carbon fibre tow is on this stove end hot-rolling, compress hot-rolling near stove end hot-rolling, carbon fibre tow is pushed;

In addition, described drying chamber is waveform, and hot blast is curve in drying chamber, repeatedly passes carbon fibre tow, to its fully heat, drying.

The utility model has the advantage of, this drying device is provided with stove end hot-rolling and compresses hot-rolling in the porch of drying chamber, carbon fibre tow after the starching is pushed, moisture extrusion with tow inside, obtain rapid draing in the time of can making tow by drying chamber, and this extruding can make the tow surfacing, make the fiber alignment in the tow neat, strengthen the bulk strength of tow.

Description of drawings

Fig. 1 is the structural representation of drying device after the carbon fiber starching that the utility model proposes.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, drying device includes drying chamber 100 after the carbon fiber starching that the utility model proposes, described drying chamber 100 two ends have import 110 and outlet 120, carbon fibre tow 300 is from import and outlet turnover, in drying chamber 100, pass, drying chamber 100 is communicated with hot air source, hot blast heats the carbon fibre tow 300 in the drying chamber 100, dry, described entrance 110 places also are provided with stove end hot-rolling 210 and compress hot-rolling 220, carbon fibre tow 300 is on this stove end hot-rolling 210, compress hot-rolling 220 near stove end hot-rolling 210, carbon fibre tow 300 is pushed; Described drying chamber 100 is waveform, and hot blast is curve in drying chamber 100, and carbon fibre tow 300 is carried out abundant drying.

Because this drying device is provided with stove end hot-rolling and compresses hot-rolling in the porch of drying chamber, carbon fibre tow passes through between stove end hot-rolling and compression hot-rolling, before entering hothouse, the moisture content of tow inside namely is extruded, can make tow in hothouse, obtain rapid draing, and this extruding can make the tow surfacing, make the fiber alignment in the tow neat, thereby strengthen the bulk strength of tow.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims

1. drying device after the carbon fiber starching, include drying chamber, described drying chamber two ends have import and outlet, and carbon fibre tow is from import and outlet turnover, in drying chamber, pass, drying chamber is communicated with hot air source, hot blast to the carbon fibre tow in the drying chamber heat, drying, it is characterized in that, described porch is provided with stove end hot-rolling and compresses hot-rolling, carbon fibre tow compresses hot-rolling near stove end hot-rolling on this stove end hot-rolling, carbon fibre tow is pushed.
