The specific embodiment:
The following correlative type that discloses is in order to the disclosed a kind of film volume structure of explanation the utility model.
Please refer to shown in Figure 2ly, it is the perspective view of the disclosed a kind of film volume structure of the utility model.Film volume structure 3 constitutes by direct coiling strip film body 32, it is characterized in that strip film body 32 is to form film volume structure 3 by no tension winding processing procedure, and film volume structure 3 is hollow cylinder, and the inside face of this film volume structure 3 is a part and direct and extraneous contact the on the surface of strip film body 32.In other words, the hollow area of film volume structure 3 does not link any central siphon.
In more detail, strip film body 32 is extremely shown in Figure 5 with flowage structure figure such as Fig. 3 of forming film volume structure 3 by no tension winding processing procedure.At first, when disclosing not feeding as yet at first (raw material is strip film body 32) to the board of reeling (scheming not show whole coiling board) in Fig. 3, the inflation axle 4 on the coiling board presents air deflating state; Then, according to as can be known shown in Figure 4, after inflation axle 4 is finished inflation, strip film body 32 is fed through in the coiling board, simultaneously since the thickness of strip film body 32 approximately between 6 microns to 12 microns, and strip film body 32 can be prestension film or other film, therefore, when reeling processing procedure, be the contraction of adopting the mode of no tension winding causes coiling to avoid excessively stretching strip film body 32 after; At last, as shown in Figure 5, finish and to inflate axle 4 behind the coiling earlier and lose heart, and lose heart at inflation axle 4 and to finish winding is taken off in the back in inflation spools 4 strip film body 32.
Wherein, according to Fig. 3 to inflation axle construction shown in Figure 5 as can be known, for increasing strip film body 32 friction force between strip film body 32 and the inflation axle 4 and bearing force (avoid strip film body 32 in inflation spools 4, to come off or the situation of slip takes place) when not having the tension winding processing procedure, on inflation axle 4, more be provided with at least one support portion 42, be that support portion 42 with a plurality of projectioies is the example explanation in present embodiment, and the arrangement mode of the support portion 42 of a plurality of projectioies is regularly arranged, certainly, this support portion 42 also can present the state of irregular alignment, and also can be sunk structure, be with, the pattern of support portion 42 not with Fig. 3 to shown in Figure 5 exceeding.
