Abstract
The utility model relates to a fixed end cover for a paper-roll core of a dust-binding machine, which is particularly used in the paper-roll core of the dust-binding machine. The fixed end cover comprises an end cover body and is characterized in that the excircle of the position where the end cover is matched with the roll core is a conical camber, and a wedge-type open slot is arranged at the edge of the conical camber. The conical camber is composed of a round surface and a conical surface, wherein the round surface is arranged ahead of the conical surface. The fixed end cover has simple, compact and reasonable structure, can lead the end cover to be matched and clamped with wedge-type blocks in the inner wall of the roll core by the wedge-type open slot, neither too tightly nor too loosely, and have no drop of chips caused by relative pivoting friction in the process of turning; in addition, the fixed end cover is convenient in use and installation, and is beneficial for improving the quality of products.
Description
Technical field
The utility model relates to fixedly end cap of a kind of binding dust machine paper bobbin core, specifically is used for and the supporting use of binding dust machine paper bobbin.
Background technology
In prior art, now the binding dust machine equipment paper bobbin of Shi Yonging fixedly the end cap cylindrical be designed to cylindrical surface, directly be inserted in a core, because the internal diameter size precision of dust sticky paper's reel core is lower, if relatively rotating of end cap and tube core will take place slightly greatly in internal diameter, wearing and tearing for a long time, the tube core can fall bits; If internal diameter is slightly little, it is too tight that cooperation will take place, inconvenient dismounting.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide wedge type piece identical block of a kind of end cap by trough with the tube in-core wall of wedge type opening, promptly can be too not tightly pine too again, can when rotating, not relatively rotate friction yet and produce bits, help improving the quality of products, and the fixing end cap of binding dust machine paper bobbin core easy to install.
According to the technical scheme that the utility model provides, binding dust machine paper bobbin core fixedly end cap comprises end cover body, and feature is that described end cover body is made as conical camber with a cylindrical of core cooperation place, and is shaped on the wedge type open slot at the conical camber edge.
Described conical camber is made of the disc and the conical surface, and before disc was arranged on the conical surface, disc diameter D1 was 78.8～79.2mm, and the disc width is 1.8～2.2mm.The maximum dimension D 2 of the conical surface is 76.8～77.2mm, and minimum diameter D3 is 74.8～75.2mm.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; The wedge type piece of end cap by wedge type open slot and tube in-core wall coincide block, promptly can be too not tightly pine too again, the friction that also can not relatively rotate when rotating produces bits; Easy to install, help improving the quality of products.
Description of drawings
Fig. 1 is the utility model structure side cutaway view.
Fig. 2 is the utility model structure master cutaway view.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 2: the utility model is to fall the bits problem for improving in the binding dust machine equipment working process, manages fixing tight end cap and does not make itself and a tube core relatively rotate friction.Described end cover body 1 is set to conical camber 2 with the cylindrical of tube core cooperation place, and is shaped on a wedge type open slot 3 at conical camber 2 edges.Described conical camber 2 is made of the disc and the conical surface, and before disc was arranged on the conical surface, disc diameter D1 was 78.8～79.2mm, and the disc width is 1.8～2.2mm.The maximum dimension D 2 of the conical surface is 76.8～77.2mm, and minimum diameter D3 is 74.8～75.2mm.The wide W1 of wedge type open slot opening is 3.8～4.2mm, and bottom width W2 is 2.8～3.2mm, and opening groove depth h1 is 2.8～3.2mm.
When the utility model uses, the conical camber 2 of end cap is filled in the binding dust paper roll column type tube, make the wedge type opening and identical the blocking of tube in-core wall wedge type piece of end cap, the maximum dimension D 2 of the minimum diameter D3～conical surface of the conical surface all is inserted in, and then other parts are installed.
