Membraneous material rolling-up mechanism
Technical field
the utility model relates to a kind of rolling-up mechanism, especially a kind of membraneous material rolling-up mechanism.
Background technology
in prior art membraneous material wrapup procedure, the general adhesive tape that adopts is membraneous material and the laminating of volume concentric mechanism, as shown in Figure 1, this kind of step that method produces membraneous material and volume concentric mechanism joint place, in wrapup procedure, utilize transition adhesive tape in the laminating transition of the step place of laminating adhesive tape, step class is increased, drop slows down, thereby reduce that step corner angle cause membraneous material compared with the compressing of small size, avoid membraneous material distortion to produce impression, the shortcoming of this membraneous material rolling-up mechanism is, in the time that the every rolling one of membraneous material is enclosed, transition adhesive tape all to be set and produce impression to prevent membraneous material distortion, rolling complexity, when losing time, productive costs is also higher.
Summary of the invention
the utility model object is: provide a kind of simple in structure, effectively prevent impression, rolling is convenient, and the low membraneous material rolling-up mechanism of productive costs.
the technical solution of the utility model is: a kind of membraneous material rolling-up mechanism, comprise volume concentric mechanism body, it is characterized in that, described volume concentric mechanism body is provided with an opening, extend along relative direction respectively at the both ends of described opening, in formation, under be symmetrical arranged and for inner side fixation wall and the outside fixation wall of fixed film material end, vertical distance between described inner side fixation wall and described outside fixation wall is less than or equal to the thickness of membraneous material, be connected with the arcwall of a center shaft taking described volume concentric mechanism body as axle center simultaneously in the end of described outside fixation wall, and the vertical distance between described arcwall and described volume concentric mechanism body equals the thickness of membraneous material, by inner side fixation wall and fixation wall fixed film material end, outside, and effectively prevent impression by arcwall, not only simple in structure, rolling is convenient, and productive costs is low.
preferably, inside face in described inner side fixation wall and/or described outside fixation wall is provided with one deck anti-skid frosted layer, increase the Joint strenght between membraneous material end and rolling-up mechanism by this anti-skid frosted layer, effectively solve the caducous problem in membraneous material end in rolling-up mechanism initial rotation process.
preferably, be provided with one deck soft medium layer at described this external surface of volume concentric mechanism, further by the characteristic of soft medium layer, discharge vertical squeese pressure, thus effectively avoided membraneous material impression, weigh wounded and damaged.
preferably, described soft medium layer is TPU, TPE, TPR, TPV or CPE elastic body soft medium layer.
the utility model has the advantages that:
1. the utility model passes through inner side fixation wall and fixation wall fixed film material end, outside, and effectively prevents impression by arcwall, not only simple in structure, and rolling is convenient, and cost is low;
2. the utility model increases the Joint strenght between membraneous material end and rolling-up mechanism by this anti-skid frosted layer, effectively solves the caducous problem in membraneous material end in rolling-up mechanism initial rotation process;
3. the utility model, further by the characteristic of soft medium layer, discharges vertical squeese pressure, thus effectively avoided membraneous material impression, weigh wounded and damaged.
Brief description of the drawings
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is prior art structural representation of the present utility model;
fig. 2 is the utility model structural scheme of mechanism;
wherein: 1 volume concentric mechanism body, 2 inner side fixation wall, 3 outside fixation wall, 4 arcwalls, 5 anti-skid frosted layers, 6 laminating adhesive tapes, 7 transition adhesive tapes.
Detailed description of the invention
embodiment: shown in Fig. 2, a kind of membraneous material rolling-up mechanism, comprise volume concentric mechanism body 1, volume concentric mechanism body 1 is provided with an opening, extend along relative direction respectively at the both ends of opening, in formation, under be symmetrical arranged and for inner side fixation wall 2 and the outside fixation wall 3 of fixed film material end, vertical distance between inner side fixation wall 2 and outside fixation wall 3 is less than or equal to the thickness of membraneous material, be connected with the arcwall 4 of a center shaft taking volume concentric mechanism body 1 as axle center simultaneously in the end of outside fixation wall 3, and the vertical distance between arcwall 4 and volume concentric mechanism body 1 equals the thickness of membraneous material, by inner side fixation wall 2 and outside fixation wall 3 fixed film material ends, and effectively prevent impression by arcwall 4, not only simple in structure, rolling is convenient, and productive costs is low, be provided with one deck anti-skid frosted layer 5 at the inside face of inner side fixation wall 3 and outside fixation wall 4 simultaneously, increase the Joint strenght between membraneous material end and rolling-up mechanism by this anti-skid frosted layer 5, effectively solve the caducous problem in membraneous material end in rolling-up mechanism initial rotation process.
be provided with one deck soft medium layer (not drawing on figure) at volume concentric mechanism body 1 outside face, further by the characteristic of soft medium layer, discharge vertical squeese pressure, thereby effectively avoided membraneous material impression, weigh wounded and damaged, this soft medium layer (not drawing on figure) is TPU, TPE, TPR, TPV or CPE elastic body soft medium layer.
above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
