Description

[0001] Glue emission pipe [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glue pipe for adhering a packaging material of a paper material during a paper-making process using paper, and more particularly to a glue pipe for a gluing apparatus having a plurality of jetting pipes for more efficiently improving gluing will be.

Generally, it is important that a certain amount of glue is continuously applied to a packaging material in a process of applying glue to a large packaging material (pasting process) in a paper finishing process for processing a large amount of paper such as a packaging material.

As a conventional technique for this purpose, there is an example in which a glue pipe in which a plurality of discharge holes are formed in a glue coating process is applied. That is, when the liquid glues are sent to the inside of the gluing pipe in a state where the gluing pipes are separated from the packing material being transported at predetermined intervals, the glues are ejected to the outside through the discharge holes and the predetermined amount is applied onto the packaging material.

However, according to the glue coating method, when the glue is stopped temporarily due to a defect in the machine or the like or the replacement of the packaging material during the coating process, the glue in the discharge hole of the glue pipe is hardened and the discharge hole is closed. In this case, the operator has to inconveniently remove the glue plugged in the discharge holes of the glue pipe.

Therefore, there is a problem that productivity of the entire packaging material is deteriorated due to delay in the paper finishing process due to the additional process of the operator.

In order to solve the above-described problems, the present invention provides a gluing apparatus which can efficiently perform a gluing process by improving a glue pipe structure applied to a gluing process in a paper finishing process such as a packaging material It has its purpose.

In order to accomplish the object of the present invention described above, the present invention has a glue pipe in which a glow inflow path is formed and a plurality of air outlets for discharging a glue discharged to the inflow path are formed, And a plurality of slender flexible plastic spouting tubes formed with a glue passage communicating with the spouting port.

Preferably, one end of the discharge pipe is exposed to the outside, and the end portion thereof is sloped to form a sloped surface, and the sloped surface is positioned to face a surface to be coated of the tributary to which the glue is to be applied.

In the present invention, a plurality of gluing pipes are applied to the glue pipe used in the glue coating process in the paper finishing process of the packaging material, thereby improving the productivity of the paper finishing process by efficiently performing the glue coating process It has excellent effect.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view showing a configuration of a gluing device according to the present invention; FIG.
FIG. 2 is a partially enlarged sectional view of the gluing structure cut along the line A-A 'in FIG. 1; FIG.

The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view showing the construction of a gluing device according to the present invention, and FIG. 2 is a partially enlarged cross-sectional view of a gluing structure cut along a line A-A 'in FIG.

As shown in FIG. 1, in the present invention, the gluing apparatus comprises a glue pipe 10 and a plurality of discharge pipes 20 mounted on the glue pipe 10.

The glue pipe 10 has a plurality of air outlets 12 formed therein for discharging the glue discharged to the inflow path 11.

Here, the glue pipe 10 is preferably opened at one end and closed at the other end, as shown in Fig.

The glue pipe 10 is in a state of being separated at a predetermined interval on a branch 30 such as paper to be coated.

The jet pipe 20 is fitted in the jet port 12 of the glue pipe 10 and a glue passage 21 communicating with the jet port 12 is formed therein.

The ejection tube 20 may preferably be made of a thin flexible plastic tube.

Here, as shown in FIG. 2, the discharge pipe 20 may be sloped to form the inclined surface 22 in a state in which one end of the discharge pipe 20 is exposed to the outside. At this time, the inclined surface 22 of the discharge tube 20 is preferably positioned in a direction opposite to the surface to be coated of the tributaries 30 to which the glue is to be applied. This provides an effect that the glue can be evenly applied to the surface to be coated of the tributary 30 through the jet tube 20 at a constant thickness.

On the other hand, the other end of the discharge pipe 20 is preferably sloped at an end thereof in the interior of the glu pipe 10 to form a sloped surface, and the sloped surface is opposed to the glu pipe 10 in the direction Lt; / RTI >

This shows the effect that the glue flowing into the glue pipe 10 can more easily enter into the glue channel of the discharge tube 20.

The gluing device according to the present invention described above works as follows.

As shown in Figs. 1 and 2, the gluing apparatus according to the present invention is positioned above the trench 30 while maintaining a predetermined gap therebetween. The tributaries 30 are conveyed in the direction of the arrow 31 while the gluing devices are fixed on the tributaries 30.

When the branch stream 30 is conveyed in the direction of the arrow 31, the glue flows into the glue pipe 10. At this time, the inflowed glue enters the closed end of the glue pipe 10, and an internal pressure is formed in the inside of the glue pipe 10 due to the glue flowing continuously.

By this internal pressure, the glu is ejected to the outside through the ejection pipe (20) fitted in the ejection port (13). The jetted glue is applied to the upper surface of the branch flow 30 to a predetermined thickness.

The glue on the outer exposed end of the discharge pipe 20 may be hardened and clogged at the end when the machine is temporarily shut down due to defects in the machine or replacement of the packaging material during the glue application process.

In this case, the operator can quickly resume the glue application process by cutting the exposed end of the spout tube 20 clogged with scissors or the like.

Accordingly, in the present invention, by applying a plurality of gluing pipes to the glue pipe used in the glue coating process in the paper finishing process of paper materials such as packing materials, the glue application process can be efficiently performed, There is an excellent effect on the.
