Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raw core rod of a wallpaper gluing machine, and more particularly to a raw core rod of a wallpaper gluing machine for applying glue to the back surface of a sheet-shaped wallpaper stuck to an interior wall surface or the like. Regarding

[0002]

2. Description of the Related Art At present, it is common to apply a wall covering material on an interior wall surface in interior construction by using a dedicated wallpaper gluing machine on site while continuously applying gluing to a sheet of wallpaper. Has become. In the conventional wallpaper gluing machine, as shown in FIG. 6, a metal round bar having a diameter smaller than that of the paper tube, which is the core of the wallpaper roll, is used as the roll core rod 4, and the hole of the roll roll 1 of the wallpaper is used. , And the original roll 1 is fixed to the original core rod 4 by the side plate 6 or the like. As shown in FIG. 7 (automatic gluing machine) and FIG. 8 (manual gluing machine), a leg portion 3 having a gluing machine main body 2 mounted on a pedestal.
The engaging groove 10 provided at the tip of the original core rod 4 is fitted to the bearing portion 7 of the paper receiving bracket 5 or the paper receiving 8 installed on both sides of the paper receiving bracket 5 and is rotatably supported. The original fabric roll 1 is arranged at a predetermined position, and the original fabric roll is pulled in the direction of the sizing process portion or the width cutting process portion to unwind the original fabric roll 1 of the wallpaper. The conventional raw core rod 4 is a round rod 11 made of metal, and a tip end portion thereof is tapered by machining to form a hook groove 10.

[0003]

However, in the conventional raw core rod, when the raw roll of wallpaper is attached to the wallpaper sizing machine, the tip of the raw core rod damages the interior such as the floor or wall. There was a problem. That is, as shown in FIG. 9, when the original roll 1 is set up and the original core rod 4 is inserted, the original core rod 4 may be dropped to damage the floor. In addition, the original core rod 4 may be dropped and damaged during transportation of the equipment. Since the end portion of the raw core rod 4 is made of metal, the interior of the floor or the like may be damaged due to dropping or collision.

There is also a problem that noise and vibration occur in the bearing portion 7 due to the raw core rod 4. That is, in the wallpaper gluing machine shown in FIG. 7 or FIG. 8, the original roll 1 dances with the unwinding of the original web, and the original core rod 4 also dances in the bearing portion 7 of the paper receiving bracket 5. Vibration and noise are generated by the collision of the metal members. This vibration may be transmitted from the paper receiving bracket 5 through the leg portion 3 to the main body 2 of the gluing machine, and may cause meandering to cause defects in width cutting and gluing. This noise may give an operator an unpleasant feeling.

The present invention solves the above conventional problems,
When installing the roll of paper roll on the wallpaper gluing machine, etc., do not damage the interior such as the floor even if the roll of core roll is dropped. The purpose is to suppress the vibration and noise of.

[0006]

In order to solve the above problems, the present invention rotatably fits the bearing portions of the paper receiving brackets provided on the legs on both sides of the wallpaper gluing machine. A wallpaper sizing machine that has a hanging groove for axial support and that is inserted into the stencil roll to attach the stencil roll of the wallpaper to the wallpaper sizing machine and rotatably support the stencil roll. A cushioning part is provided at both ends of the raw core rod to reduce impact. With this configuration, when inserting the raw core rod into the hole of the raw roll, even if the raw core rod is dropped onto the floor or collided with the wall, the interior of the floor or the like is damaged. The attachment can be prevented by the buffer portion.

Further, the portion where the hooking groove of the original core rod contacts the bearing portion of the wallpaper sizing machine is made of resin. With this configuration, it is possible to suppress the vibration and noise generated by the collision of the metal members due to the looseness of the retaining groove.
