Description

[Detailed Description of the Invention] This invention relates to a wallpaper gluing machine for applying a glue liquid to the back side of wallpaper at the site when pasting wallpaper on walls, ceilings, etc.

In conventional wallpaper pasting machines, the amount of paste applied can be adjusted using a doctor roller that works in conjunction with a pasting roller.

The glue application amount adjustment mechanism has a doctor roller bearing hole located eccentrically from the center of rotation of a rotatable disk bearing.
By rotating the disc bearing, the position of the doctor roller relative to the sizing roller can be changed, and the thickness of the sizing liquid can be adjusted.

(For example, see Utility Model Publication No. 54-13400). By the way, if the doctor roller lifts more than necessary on the glue thickness adjustment part of the glue application roller, the viscosity of the glue increases the resistance between both rollers, increasing the force applied to the roller bearing and pulling the wallpaper. This requires a large amount of force, resulting in poor workability.

Therefore, in order to allow the excess glue to fall under its own weight before reaching the glue thickness adjusting part, it is desirable to provide the glue thickness adjusting part as high as possible above the glue liquid level. It is desirable that the height of the part from the glue surface be constant.

However, in the conventional device described above, the glue thickness is adjusted by eccentric rotation of the doctor roller, so the height of the doctor roller changes depending on the rotation angle (degree of adjustment), and the force applied to the bearing and The tensile strength of the wallpaper also changes.

Therefore, each time the glue thickness is adjusted, the tensile force changes, making the work difficult.

This invention aims to provide a wallpaper gluing machine in which the doctor roller is moved horizontally to adjust the glue thickness, and the force applied to the bearing and the wallpaper tension force do not change even when the glue thickness is adjusted. It is something to do.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIG. 1, a gluing roller 3, a doctor roller 4, and a leveling roller 5 are each rotatably installed between the side plates 2 of the main frame having the glue box 1.
A stay roller 7 and a drive roller 8 are installed on the side frame 6 placed on the side frame 6, and as shown in FIG. Glue is applied to the back side of 9.

As shown in FIGS. 2 and 3, the cylindrical portion of the bearing 10 of the doctor roller 4 is inserted into a horizontally long hole 12 of a bearing member 11 fixed to the side plate 2 by fitting. The square base is fitted into a horizontal slide groove 11' of the bearing member 11, so that the bearing 10 can move within the elongated hole 12 only in the horizontal direction.

An adjusting arm 13 is rotatably screwed onto the upper part of the bearing members 1, 1, and a pot-shaped hole 14 is formed in the adjusting arm 13.

This hole 14 is formed to be long in the direction intersecting the elongated hole 12.

The bearing 10 passes through the elongated hole 12 and the pothole 14 in common, and the groove 10 provided on the outer periphery of the bearing 10 is fitted into the small diameter portion of the hole 14, so that the bearing 10 and the adjustment arm 13 are engaged. , by rotating the arm 13, the bearing 10 comes to move horizontally within (L12) of the bearing member 11.

An inverted dog-shaped locking member 15 is fixed to the adjustment arm 13, and a tightening screw 16 is inserted through this member 15.

Furthermore, as shown in FIG. 3, a plate-shaped fixture 17 with a bulged middle portion is fixed to the side plate 2, and the upper edge of the middle portion of this fixture 17 has an arc shape along the rotational direction of the arm 13. The arm 13 and the member 15 are formed as shown in FIG.
The upper edge of the fixture 17 is located between them.

An inverted U-shaped intermediate fitting 18 is placed over the upper edge of the fixing fitting 17, and the tightening screw 16 is threaded through the intermediate fitting 18, and its tip is pressed against the fixing fitting 17. A screw 16 and an intermediate metal fitting 18 are fixed to.

During this fixing operation, since no tightening force of the screw 16 is applied to the adjustment arm 13 and the locking member 15, the arm 1
3 will not be twisted and therefore the bearing 10
No torsional force is applied to it.

The fixing fitting 17 also has a display 19 indicating the rotation angle of the arm 13, that is, a display indicating the horizontal movement distance of the bearing 10.The wallpaper pasting machine of this invention is constructed as described above.
Next, its effect will be explained.

As shown in FIG. 4, when the adjustment arm 13 is rotated to the left from the state where the bearing 10 is at the right end of the hole 12 as shown in FIG. 5, the bearing 10 moves horizontally within the hole 12. The doctor roller 4 moves in a direction away from the pasting roller 3, and the thickness of the pasting liquid applied to the wallpaper 8 is adjusted.

When the doctor roller 4 is at the desired position relative to the gluing roller 3, the tightening screw 16 is tightened and fixed, thereby maintaining the desired degree of adjustment.

As described above, according to the wallpaper gluing machine of this invention, the doctor roller can be moved only in the horizontal direction by rotating the adjustment arm, and the doctor roller can be stopped at any position. By simply rotating the adjustment arm, the position of the doctor roller relative to the gluing roller can be finely adjusted without changing the tensile force of the wallpaper, and the amount of glue applied to the wallpaper can be adjusted. .

In addition, a plate-shaped fixing metal fitting along the direction of rotation of the arm is fixed to the side plate, an inverted U-shaped intermediate metal fitting is interposed in this fixing metal fitting, and the fixing screw inserted through the arm is screwed through the intermediate metal fitting to fix its tip. If the arm is pressed into contact with the metal fitting and can be fixed at any rotational position, the arm will not be twisted, no torsional force will be applied to the bearing, and the rotation of the roller will not be hindered.
