Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.Wherein,
Fig. 1 is the structural representation of secondary material returning structure of the present utility model.
Wherein: 1 for material returned ring, 2 be stripping attachment, 3 be die springs.
Detailed description of the invention
Secondary material returning structure described in the utility model, it comprises: material returned ring 1, stripping attachment 2 and die springs 3.
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with detailed description of the invention.
First, alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the utility model.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
Secondly; the utility model utilizes structural representation etc. to be described in detail; when describing the utility model embodiment in detail; for ease of explanation; represent that the schematic diagram of secondary material returning structure structure can be disobeyed general ratio and be made partial enlargement; and described schematic diagram is example, it should not limit the scope of the utility model protection at this.In addition, the three dimensions of length, width and the degree of depth should be comprised in actual fabrication.Embodiment one
Refer to Fig. 1, Fig. 1 is the structural representation of secondary material returning structure of the present utility model.As shown in Figure 1, comprise material returned ring 1, stripping attachment 2 and die springs 3, described stripping attachment 2 is divided into material returned head (not shown) from top to bottom successively, material returned post (not shown) and material returned chassis (not shown), described material returned head, material returned post and material returned chassis are structure as a whole, the diameter of described material returned head becomes large from top to down gradually, described material returned post is cylindric, the upper end of described material returned post is connected with described material returned head, the lower end of described material returned post is connected with described material returned chassis, the diameter on described material returned chassis is greater than the diameter of described material returned post, described material returned ring 1 is in hollow structure, described material returned ring 1 is set on described material returned post, described material returned ring 1 comprises material returned annulated column (not shown) and material returned ring base (not shown), described material returned annulated column and material returned ring base are structure as a whole, the external diameter of described material returned annulated column is less than the external diameter of described material returned ring base, the internal diameter of described material returned annulated column equals the internal diameter of described material returned ring base, described die springs 3 is set on described material returned post, material returned ring base described in the upper-end contact of described die springs 3, material returned chassis described in the lower end in contact of described die springs 3.
