Membrane reel fixing device for a membrane strapping dispenser

Abstract

A membrane reel fixing device for a membrane strapping dispenser includes a reel pivot having its outer circumference formed integral with three support ribs respectively connected with a convex holding plate extending along the circumference of the reel pivot. The three holding plates have their lower sides suspended in midair; therefore, when pressed diametrically, the holding plates can be elastically shifted and deformed and after a membrane reel is fitted on the reel pivot, the holding plates can firmly prop the inner wall of the central tube of the membrane reel. Different-sized membrane reels can be firmly fitted on the reel pivot by means of the holding plates that can be elastically shifted and deformed.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a membrane reel fixing device for a membrane strapping dispenser, particularly to one able to firmly fix a membrane reel in position and applicable to different-sized membrane reels. [0003] 2. Description of the Prior Art [0004] Generally, a membrane reel has a membrane wound thereon to be released and strapped on articles so as to prevent them from swaying and falling when they are stored or transported. Nowadays, a membrane strapping dispenser is widely employed for the convenience of carrying out membrane releasing and strapping work. A conventional membrane strapping dispenser 10, as shown in FIG. 1, includes a reel pivot 11 and a handle 12. The reel pivot 11 is formed with a hollow shaft 111 having a lower end extending outward diametrically and forming a stopping rim 112 and the outer circumference of the other end formed with three support ribs 113 extending axially. Each support rib...

AI Technical Summary

Benefits of technology

[0006] The objective of the invention is to offer a membrane reel fixing device for a membrane-strapping dispenser, provided with a reel pivot having its circumference formed integral with three support ribs extending outward axially. Each support rid is connected with a convex holding plate extending along the circumference of the reel pivot. The three holding plates have their lower sides opposite to a handle fitting rod suspended in midair; therefore, when pressed diametrically, the holding plates can be elastically shifted and deformed and after a membrane reel is fitted on the reel pivot, the holding plates are able to firmly press the inner wall of the central tube of the membrane reel. Thus, different-sized membrane reels can be firmly fitted on the reel pivot of the membrane strapping dispenser of this invention by means of the holding plates that can be elastically shifted and deformed.

Problems solved by technology

As a result, it is always found that the membrane reel cannot be fitted on the reel pivot or that the membrane reel cannot be firmly fixed in position after it is fitted on the reel pivot.
