SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problems of the prior art and providing a cutting device is put in exhibition for tensile membrane to change present not enough.
In order to achieve the above purpose, the utility model discloses a technical scheme is:
a spreading and cutting device for a stretched film is characterized by comprising an inner sleeve and an outer sleeve which are coaxially corresponding to each other;
the same ends of the inner sleeve and the outer sleeve are fixedly connected with each other through a circular ring side baffle; a gap for placing the film cylinder is reserved between the inner sleeve and the outer sleeve;
the outer sleeve is provided with an opening, and the outer sleeve forms an unclosed cylindrical structure under the influence of the opening; the outer sleeve and the corresponding edge of the opening are respectively provided with saw teeth for tearing the thin film.
Further, the outer sleeve has a length that is shorter than the length of the inner sleeve.
Furthermore, a rotating sleeve which is rotatably connected with the inner sleeve is arranged at the outer diameter of the inner sleeve.
Further, the length of the rotating sleeve is shorter than the length of the inner sleeve.
Furthermore, the inner skleeve is kept away from the one end of ring side shield is equipped with spacing lug, just swivel sleeve passes through spacing lug with the mutual spacing rotation of inner skleeve is connected.
The utility model discloses rational in infrastructure, convenient to use, the internal diameter of a film section of thick bamboo inserts the external diameter of inner skleeve, rotates under swivel sleeve's effect, is convenient for drag the rotation of an in-process film section of thick bamboo. When the thin film is pulled, the thin film extends outwards through the opening on the outer sleeve, and when the thin film needs to be cut off, the thin film can be torn by pulling the thin film at the sawtooth position with force.

Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to fig. 1 to 5, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
Referring to fig. 1 to 5, the present invention relates to a stretching and cutting device for stretching a film, which comprises an inner sleeve 2 and an outer sleeve 1 coaxially corresponding to each other;
