Description

Paper tube construction

This creation relates to a reel used for elongate continuous belt winding, and more particularly to a paper tube construction which can be used as a reel when the belt is wound.

The transfer film, the light guide plate and the like are mainly processed by processing the long continuous belt body formed by the resin, and then cutting according to the required size. After the belt body is formed, the paper tube is used as a reel. The belt is wound around the outer circumference of the paper tube to facilitate the storage, transportation and subsequent processing of the belt.

A conventional seamless paper tube for winding the aforementioned belt body is disclosed in the publication No. 377875, wherein the paper tube comprises an inner tube and an outer tube, wherein the inner tube is of one to several The first paper tape layer is formed by winding a second paper tape wrapped around the outer circumference of the inner tube, and the second paper tape is formed with a first chamfer and a second chamfer at the two ends, respectively. The two chamfers cooperate with the first chamfer to form a relatively complementary state, and the outer peripheral surface of the outer tube is in a state of no groove or embossing.

When the strip is to be wound around the paper tube, the end of the strip is first attached to the outer peripheral surface of the paper tube, and then the strip layer is wound around the paper tube along the tangential direction of the paper tube, and the strip is wound. In the middle, it is necessary to apply an appropriate pulling force to the belt body, so that the belt body is in an appropriate stretch state, and the winding state of the belt body is stabilized, thereby avoiding accidents in which the belt body is scattered during subsequent handling or processing.

The belt system resin material is formed, and when the belt layer is wound, the belt is attached One end attached to the surface of the paper tube is convex on the surface of the paper tube, and when the belt is wound in layers, the belt protrudes from the end of the surface of the paper tube, and is attached to the outer circumference of the end portion for subsequent winding. The surface of the belt body forms a local relative force, and the local relative force easily causes damage to the surface of the belt which is subsequently wound and contacts the end portion, and the relative force is in addition to the direct contact with the end portion. In addition to the damage caused by the surface of the belt, the surface of the belt that is subsequently wound on the outer circumference is also affected. The thinner the thickness of the belt, the more the number of turns caused by the damage at the end, the part of the surface of the belt is damaged. It will be difficult to use again.

The main object of the present invention is to provide a paper tube construction for use as a reel for winding a belt.

The present invention relates to a paper tube structure comprising a main pipe and a skin, wherein the main pipe is a circular pipe body formed by winding one to several paper tape layers, and the skin is made of a long tape body made of paper. One end of the skin is a first end, and the other end is a second end. The first end abuts against the outer circumference of the main pipe, and the skin is wrapped around the outer circumference of the main pipe along the circular tangential direction of the main pipe, and the end surface of the first end is a The slope is inclined, and the slope faces the outer circumferential direction of the paper tube, and the portion of the skin adjacent to the second end abuts the slope.

When the belt is wound around the outer circumference of the paper tube, the portion of the belt attached to the outer layer is smooth, and the surface of the belt does not cause damage such as indentation, and the belt body can be fully utilized.

The first figure is a partially enlarged schematic view of the end face of the present embodiment.

The second figure is a schematic diagram of the state of use of the present embodiment.

As shown in the first figure, the embodiment of the present paper tube structure includes a supervisor (10) And a skin (20), wherein the main pipe (10) is a circular pipe body formed by winding one to several paper tape layers, and the skin (20) is a long tape body made of paper, the skin (20) one end is a first end (22) and the other end is a second end (24), the first end (22) abuts against the outer circumference of the main pipe (10), and the skin (20) is along the main pipe (10) The circular tangential direction is wrapped around the outer circumference of the main pipe (10), the end surface of the first end (22) is a slope (26), and the inclined surface (26) faces the outer circumferential direction of the paper tube, and the skin (20) is adjacent The portion of the second end (24) abuts against the inclined surface (26), and the outer surface of the skin (20) is smoothed when the skin (20) is wrapped around the outer circumference of the main pipe (10) by the formation of the inclined surface (26). status.

As shown in the second figure, a resin-formed elongated continuous belt (90) is wound around the foregoing In the outer circumference of the embodiment, the end (92) of one end of the belt body (90) abuts against the outer surface of the skin (20), and the end portion (92) abuts against the second end (24), and then, along The circular tangential direction of the main pipe (10) winds the belt body (90) layer, and the outer surface of the skin (20) adjacent to the second end is due to the end portion (92) and the second end (24) abutting each other. Between the outer surface of the strip body (90) adjacent to the end portion (92), a smooth and non-marking convex shape is formed, and the portion of the strip body (90) that is subsequently wound is supported by the aforementioned outer surface, and the end portion (92) The tape body (90) which is not in contact with the subsequent winding and attached to the outer periphery of the end portion (92) forms a partial relative force, and accordingly, the paper tube of the present invention is used as a belt having a high surface quality requirement. The body (90) is wound on the reel, and the surface of the belt body (90) does not cause damage such as indentation, and the belt body (90) can be fully utilized.
