Fig. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic structural view of the middle equally-divided supporting member of the present invention.
In the figure: 1 halving support piece, 2 annular springs, 101 arc pieces, 102 support pieces, 103 arc limiting pieces, 104 arc mounting blocks, 105 arc grooves and 106 inclined plane notches.
Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention;
referring to fig. 1-2, the gas expansion shaft reducing shaft sleeve for carbon fiber paper production comprises an annular spring 2 and a plurality of halved supporting pieces 1 which are combined with each other, wherein the plurality of halved supporting pieces 1 are combined with each other and then assembled into a whole through the annular spring 2; the equal division supporting pieces 1 are all made of polypropylene materials; as shown in fig. 1, in the present embodiment, the equally divided supporting members 1 are three in number, and the three equally divided supporting members 1 are identical in structure.
In this embodiment, the number of the ring springs 2 is two, and two arc-shaped mounting blocks 104 are mounted on the outer side of each arc-shaped piece 101 and between the two support pieces 102.
The three equally-divided supporting pieces 1 are bound and connected into a whole by two annular springs 2 according to the mode shown in figure 1, and the shape of the three equally-divided supporting pieces is similar to a cylinder, namely a reducing shaft sleeve. The reducing shaft sleeve is sleeved on the physiosis shaft, the winding drum is sleeved on the reducing shaft sleeve, the physiosis shaft is inflated to radially extrude the reducing shaft sleeve, so that the winding drum is stably supported, and the outer wall of the winding drum can be used for winding carbon fiber paper.
Each equally-divided support 1 comprises an arc-shaped piece 101, support pieces 102 are fixed at two ends of the outer side of each arc-shaped piece 101, an arc-shaped mounting block 104 is mounted between the outer side of each arc-shaped piece 101 and the two support pieces 102, an arc-shaped groove 105 is formed in the outer side of each arc-shaped mounting block 104, and the arc-shaped grooves 105 are matched with the annular springs 2;
the rear ends of each arc-shaped piece 101 and the support piece 102 are both provided with a limiting arc-shaped piece 103, and the radius of the outer circumference of the limiting arc-shaped piece 103 is larger than the radius of the outer circumference of any one of the arc-shaped pieces 101 and the arc-shaped mounting blocks 104;
the front end of each support piece 102 is provided with a bevel notch 106.
When the reel lies in the installation of reducing shaft sleeve, because inclined plane incision 106 has been seted up to the front end of backing sheet 102, even if consequently still can realize convenient cup jointing to the paper reel that the tip warp, the installation of reel is simple more high-efficient, reel and reducing shaft sleeve installation back, because spacing arc piece 103 is installed to the rear end of backing sheet 102, consequently can carry on spacingly to the reel, make it can realize stable location with the reducing shaft sleeve after the equipment, when avoiding leading to the fact follow-up rolling carbon fiber paper because of its mounted position skew, the carbon fiber paper atress inequality causes the paper fracture.
