Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, the technical scheme of the expansion mechanism of a kind of reel machine is provided, rotating shaft and refill cylinder can be made to fix firmly, prevent refill cylinder from skidding, ensure production efficiency, reduce the abrasion of refill cylinder, improve the reuse ratio of refill cylinder, reduce production cost。
Technical problem to be solved in the utility model realizes by the following technical solutions: the expansion mechanism of a kind of reel machine, including rotating shaft, the front end of described rotating shaft is provided with expansion mechanism, and described expansion mechanism includes positive rectangular pyramid, four holding blocks, sliding panel and limiting plate；Described positive rectangular pyramid is installed in the front end of rotating shaft, and the conical surface of positive rectangular pyramid is provided with dovetail groove；The lower end of described holding block is provided with the dovetails being slidably matched with dovetail groove, and the rear end of holding block is provided with push rod；Described sliding panel is slidably mounted in rotating shaft, and described limiting plate is fixed in rotating shaft, is provided with spring between sliding panel and limiting plate, sliding panel under the action of the spring with ejector pin contact。
The technical solution of the utility model also has: the rear end of described push rod is provided with roller, it is possible to reduce push rod end and the abrasion of sliding panel, extends the service life of expansion mechanism。
The technical solution of the utility model also have: described holding block is provided with step, during use, two faces of step respectively with the inner headed face of refill cylinder and end contact。
The technical solution of the utility model also has: the surface of described step is provided with anti-slip veins, can increase the frictional force between holding block and refill cylinder, it is prevented that skid。
The technical solution of the utility model also has: the periphery of described rotating shaft is provided with gathering sill, and described sliding panel is provided with the slide block being slidably matched with gathering sill。
The technical solution of the utility model also has: described spring housing is located at the outside of rotating shaft。
The technical solution of the utility model also has: described limiting plate is threaded connection and is arranged in rotating shaft。
Operation principle of the present utility model: during non-working condition, holding block is pushed to the front end of positive rectangular pyramid under the action of the spring, and the distending of holding block is apart from little。During use, expansion mechanism being moved axially inward along rotating shaft under the effect of mobile device, the end of refill cylinder promotes holding block, holding block distending, fixes until the inner headed face swelling with refill cylinder。
Relative to prior art, having the beneficial effect that of the expansion mechanism of this utility model reel machine can firmly fix with refill cylinder, it is prevented that refill cylinder skids, thus ensureing production efficiency, reduce the abrasion of refill cylinder, improve the reuse ratio of refill cylinder, reduce production cost。
