Description

Cushion Paper Tube and Method of Manufacturing the same

The present invention relates to a cushioning paper tube and a method of manufacturing the same, and particularly to prevent the occurrence of press marks (or transfer marks) on the wound when winding the wound (paper, film, textile fabric or thread, etc.). In addition, the present invention relates to a cushioning tube and a method of manufacturing the same, which can wind a wound product without using an adhesive tape.

Paper tubes (紙 管) is generally manufactured in a cylindrical shape for storing and moving in the state of winding a variety of papers, film paper, fabric fabric or thread wound.

Currently, the branch pipes in the market are mostly coated with rubber materials such as NBR and NR on the outer surface of the reference core made of aluminum or FRP (glass fiber). This type of paper pipe uses NBR and NR, which are rubber materials with excellent abrasion resistance. However, due to its high hardness, the paper tube is not sufficient to reduce the loss rate of the film due to the press marks due to its ability to prevent crushing when the wound is wound. When used for a period of time, there was a problem that the phenomenon of preventing the pressing marks by hardening of the material itself disappeared.

In addition, the aluminum used as the material of the reference core has a high price, which not only increases the cost of manufacturing the paper tubes, but also cannot be cut by the cutting machine, so that additional windings must be cut after winding the winding back to the cuttable reference core. There was a problem of generating the process.

In addition, in the case of winding various films on the paper pipe, the end of the film product is wound on the surface of the paper pipe by using the adhesive tape, and then the film is wound on the paper pipe while rotating the paper pipe. Due to the thickness, the surface of the branch pipe becomes uneven, which causes wrinkles in the wound film product. In other words, due to the thickness of the adhesive tape that bonds the surface of the paper pipe to the beginning of the film, it causes a fatal damage that causes press marks on the wound film. It causes a problem.

In particular, such a problem is more serious in the case of expensive products such as high-functional thin film used as a core material of high-tech industries such as semiconductors.

Figure 2 is a block diagram showing a cushioning paper manufacturing method according to the present invention.

Hereinafter, with reference to the accompanying drawings an embodiment of a cushioning tube and a manufacturing method according to the present invention will be described in detail.

1 is a view showing a cross-sectional view of the cushion paper tube according to the present invention.

Cushion paper tube according to the present invention is to wind the wound, such as paper, film, fabric fabric or thread, it is composed of a reference core 10 and the elastic tube 20 which is installed on the outer surface of the reference core 10. .

The reference core 10 is made of a hollow cylindrical shape, the material is manufactured by selecting any one of PE, PET, ABS, PVC. Of course, it is also possible to be made of a steel material such as aluminum, but it is preferable to avoid the steel material if possible in consideration of problems such as when cutting with a cutter.

The elastic tube 20 is fitted to the outer surface of the reference core 10, the material is made of silicon.

In more detail, the elastic tube 20 is made of silicon and has a constant elasticity and its shape is made of a hollow cylindrical shape, the inner diameter of which is made 1 to 2 mm smaller than the outer diameter of the reference core 10. . In this way, the elastic tube 20 has a constant elasticity in itself and the inner diameter is manufactured to be 1 to 2 mm smaller than the outer diameter of the reference core 10, the elastic tube 20 is firmly in close contact with the outer surface of the reference core (10).

In addition, although the elastic tube 20 may be made of silicon alone, the elastic tube 20 may be manufactured by adding a part of an adhesive raw material (that is, an adhesive) to the silicone to impart adhesive performance to the elastic tube 20. At this time, the mixing ratio of the silicone solution and the adhesive raw material is preferably mixed in a weight ratio of 9: 1.

It will be described with respect to the cushioning pipe manufacturing method according to the present invention for producing a cushioning paper as described above.

Figure 2 is a block diagram showing a cushioning paper manufacturing method according to the present invention.

Cushion paper manufacturing method according to the present invention comprises a molding step (S100), soaking step (S200), fitting step (S300), drying step (S400) and polishing step (S500).

The forming step (S100) is a process of forming the elastic tube 20 surrounding the outer surface of the reference core 10. In more detail, the forming step (S100) is to extrude the silicon by an extruder to form a tube, the inner diameter is a process of forming 1 ~ 2mm smaller than the outer diameter of the reference core (10). The reason for making the inner diameter of the elastic tube 20 smaller than that of the reference core 10 is that the elastic force and diameter of the elastic tube 20 are small when the elastic tube 20 is installed on the outer surface of the reference core 10. This is to firmly adhere the elastic tube 20 to the reference core 10 by the pressure generated. In other words, when extruding in the extruder, the elastic tube 20 is formed by extruding the sheet to have a thickness of 3 to 4 mm.

On the other hand, when extruding with an extruder to mold the elastic tube 20, the adhesive is mixed with silicon (that is, adhesive) to extrude. This allows the elastic tube 20 to have an adhesive force, so that the end of the film can be attached to the cushion paper tube without using a tape when the film is wound on the cushion paper tube according to the present invention. In more detail, when extruded with an extruder, a silicone solution and an adhesive are mixed at a weight ratio of 9: 1, and then introduced into an extruder, and then the extruded mixture is manufactured to produce an elastic tube 20 having adhesive force.

The soaking step (S200) is a process of literally soaking the elastic tube 20 in a solution to soften the tissue and increase the volume. That is, the soaking step (S200) is a process of softening the elastic tube 20 in a solid form by immersing the elastic tube 20 in a synthetic raw material solution for softening silicon for 1 to 2 hours.

The fitting step (S300) is a process of fitting the bulky elastic tube 20 through the soaking step (S200) on the outer surface of the reference core 10.

In the forming step (S100), the inner diameter of the elastic tube 20 is molded smaller than the outer diameter of the reference core 10, and in the soaking step (S200), the elasticity is made slightly smaller to insert the reference core 10 therein The volume of the tube 20 is increased while at the same time making the tissue flexible. Since the volume is increased in the so-called step (S200) and the structure is flexible, the elastic tube on the outer surface of the reference core 10 in the fitting step (S300) even if the elastic tube 20 is made small in the molding step (S100). 20 can be inserted smoothly.

The drying step (S400) is a process of drying the elastic tube 20 fitted in the outer surface of the reference core 10 in a clean room having a temperature of 10 ~ 25 ℃. In order to easily insert the reference core 10 inside the elastic tube 20, the process called the elastic tube 20 in the soaking step (S200), through the soaking step (S200) is bulky and tissue The flexible elastic tube 20 is returned to the volume and tissue state of the elastic tube 20 before passing through the drying step (S400), the soaking step (S200).

Therefore, when the elastic tube 20 passes through the drying step S400, the elastic tube 20 is firmly attached to the outer surface of the reference core 10.

The polishing step (S500) is a process of polishing the outer surface of the dried elastic tube 20. Since the elastic tube 20 extruded and molded in the forming step (S100) is not smooth because fine protrusions are formed on the surface thereof, the elastic tube 20 is polished by grinding a grindstone polisher about 0.5 to 1 mm to produce an elastic tube 20 having a smooth surface. . As a result, a cushion paper tube is firmly enclosed on the outer surface of the elastic tube 20 and the reference core 10 having a smooth surface.
