Abstract
The utility model discloses a large tow carbon fiber expanding device, which comprises a take-up block, at least two heating rollers arranged in a tangency manner and a framework. The heating rollers are connected with the framework in a rotary manner. The take-up block is driven to rotate by a driving device. The preferred number of the heating rollers is 2 to 10 pairs, which are arranged on the framework at intervals. The axle of each heating roller is parallel to the axle of the take-up block. The heating roller can be driven to rotate by a motor. The utility model has simple structure and low cost. The thickness of the carbon fiber product expanded by the utility model is little, the fiber utilization factor is high and the excellent performance of the carbon fiber is given full play to.
Description
Technical field
The utility model relates to a kind of fiber process device, particularly relates to a kind of expanding unit of large-tow carbon fiber.
Background technology
The carbon fiber that is widely used in fields such as civil construction, Aero-Space, automobile, sports goods, the energy and health care, electronic communication, oil exploitation, infrastructure at present, be divided into little tow carbon fiber and large-tow carbon fiber, its medium and small tow is based on 1K, 3K, 6K, 12K and 24K (1K is 1000 threads), big tow is more than the 48K, comprises 60K, 120K, 360K and 480K etc.; Because large-tow carbon fiber is to intersect the bigger fibre bundle of diameter that twines between a kind of fiber that is bonded by adhesives such as carbon fiber and resins mutually, thereby the products thickness of being made by the fibre bundle of this structure is big, and the carbon fiber utilization rate is low, and the carbon fiber performance is not in full use.
The utility model content
The technical problems to be solved in the utility model provides a kind of large-tow carbon fiber expanding unit, and little, the fiber utilization rate height of products thickness by the carbon fiber after this device expansion is made can make the carbon fiber performance be not fully exerted.
For solving the problems of the technologies described above, the utility model adopts so a kind of large-tow carbon fiber expanding unit, it comprises the heating roller and the frame of rolling tube, at least one pair of tangent setting, and described heating roller and frame are rotationally connected, and described rolling tube is driven by drive unit and rotates.
After adopting said structure, because the heating roller of at least one pair of tangent setting is installed on frame rotationally, thereby when the rolling tube drives rotation by drive unit, large-tow carbon fiber is through the hot extrusion of the heating roller of tangent setting, adhesive melted by heat such as the resin in the carbon fiber bundle, and each the bar carbon fiber exhibition in the carbon fiber bundle scatters after the extruding that is subjected to heating roller, and rolling is on described rolling tube equably.Because the carbon fiber after sprawling is compared with large-tow carbon fiber, its thickness reduces greatly, thereby it is little by its products thickness that makes, and intersection winding mutually of the carbon fiber after sprawling, thereby make that the product strength that makes is bigger, the fiber utilization rate improves greatly, makes the premium properties of carbon fiber obtain giving full play to.
As a kind of improvement of the present utility model, described heating roller is preferably 2～10 pairs, and the space certain distance is arranged on the described frame.Adopt such structure, can make the adhesive melts in the carbon fiber bundle more abundant, push more thorough, thereby make carbon fiber thinner, more equably rolling on described rolling tube.
As further improvement of the utility model, described heating roller can be rotated by motor-driven.Adopt such structure, can increase the tractive force that carbon fiber bundle is subjected to, thereby enhance productivity.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model large-tow carbon fiber expanding unit.
The specific embodiment
Referring to a kind of large-tow carbon fiber expanding unit shown in Figure 1, it comprises the heating roller 2a of rolling tube 1, at least one pair of tangent setting, 2b and frame 3, described heating roller 2a, 2b is rotationally connected by bearing or axle sleeve and described frame 3, described rolling tube 1 by drive unit for example motor-driven rotate.
In the utility model, described heating roller 2a, 2b can heat by modes such as known electrical heating, oily heating, steam heated or electromagnetism heating.
As shown in Figure 1, described heating roller 2a, 2b preferably has 2～10 pairs, and it is how right to be arranged to, and as more than 10 pairs, and these heating roller space certain distances are installed on the described frame 3 rotationally by bearing or axle sleeve.These heating rollers 2a, the axis of the axis of 2b and described rolling tube 1 is arranged in parallel.
For strengthening the tractive force of carbon fiber bundle, enhance productivity, described heating roller 2a, 2b can be driven by motor 4 and rotate.As shown in Figure 1, described motor 4 can pass through transmission mechanism, drives heating roller 2a as be with 5 synchronously, synchronizing wheel etc. and rotates; In the utility model, also can adopt each to heating roller 2a, 2b is rotated by a motor-driven respectively, and is not shown in the figures.
During the utility model work, at first will heat roller 2a, the 2b electrical heating is to the adhesive melts temperature, then large-tow carbon fiber 6 unreeling the tube 7 on being installed in the coiled hair frame exported, and through multiple tracks heating roller 2a, drawout after the 2b hot extrusion, at last equably rolling to rolling tube 1.
Large-tow carbon fiber expanding unit of the present utility model is simple in structure, with low cost, and through on probation, has obtained good effect.
