Description

[Detailed description of the invention] (Industrial application field) This invention is a wallpaper gluing machine that is used to apply glue to the back side of wallpaper on-site when pasting wallpaper on the walls and ceilings of buildings. This invention relates to a type of wallpaper that makes it easy to peel off the cut ends after cutting the wallpaper.

(Prior art) As a wallpaper gluing machine, a gluing roller is provided in the center of a rectangular glue box, and a smoothing roller is supported between the gluing roller and the front plate of the glue box. It is known that a wallpaper cutting ruler is provided in a straight line in the width direction below the front plate at a slight interval. and,
In this wallpaper gluing machine, the back side of the wallpaper is pressed against the gluing roller and the leveling roller in order while the wallpaper is run and glued, and a predetermined length of the glued wallpaper is placed below the front plate of the glue box. The wallpaper was cut by placing the knife on a wallpaper cutting ruler and sliding the knife along the ruler.

(Problem to be solved by the invention) Conventional glue boxes were made by bending a thin metal plate, and the front plate was formed with a smooth surface. When the wallpaper that had been pulled out was bent downward and placed against a wallpaper cutting ruler, the back side of the wallpaper coated with glue was adhered to the front surface of the glue box. Therefore, especially when cutting thin wallpaper, there was a problem in that the wallpaper adhered to the front plate was difficult to peel off and sometimes broke.

In this invention, the front panel of the glue box is slightly modified so that it is difficult to adhere to the front panel and the wallpaper on the front panel can be easily removed.

(Means for solving the problem) A gluing roller is provided in the center of a rectangular glue box, and a smoothing roller is supported between the gluing roller and the front plate of the glue box. In a wallpaper gluing machine in which wallpaper cutting rulers are provided in a straight line in the width direction at a slight distance from below, a protrusion is provided on the front plate of the glue box for lifting the wallpaper from the front plate. The number of protrusions to be attached is preferably four in total, two at each end of the wallpaper and two in the middle, and can be increased or decreased depending on the width of the wallpaper.

(Function) When the glued wallpaper is cut by applying it to the wallpaper cutting ruler below the front plate of the glue box, the wallpaper comes into contact with the protrusions on the front plate surface and lifts from the front plate surface, causing the front plate surface and the edges of the wallpaper to A gap corresponding to the thickness of the protrusion will be created between the ends, so insert your fingertips into this gap and separate the wallpaper from the front panel, then pull out the wallpaper again and restart gluing.

(Example) In FIG. 1, a glue box 1 is made to have a rectangular plan view by bending a thin metal plate, and a glue roller 2 is provided in the center of the glue box 1, and a doctor roller 3 is provided behind it. However, a rear press roller 4 is provided at the upper rear, a front press roller 5 is provided at the upper front, and a smoothing roller 6 is provided at the rear, and these doctor roller 3, rear press roller 4, and front press roller 5 and a leveling roller 6 are connected to the gluing roller 2 by gears so as to rotate at a predetermined speed ratio. The gears connecting the rollers 2, 3, 4, 5, and 6 are fixed to shaft ends that protrude laterally from the side plate 1a of the glue box 1, and are covered with a gear cover 7 (see FIG. 2). ing.

The front plate 1b of the glue box 1 has a vertical surface with a smooth surface, and front plate reinforcing plates 8 are fixed to both left and right ends of the front plate 1b. A stopper 9 that extends and contacts the bottom plate 1d of the glue box 1 is fixed inside the intersection of the front reinforcing plate 8 and the side plate 1a of the glue box 1. On the other hand, the rear plate 1c of the glue box 1
A rear reinforcing plate 10 is fixed to the rear reinforcing plate 1.
0 extends below the lower edge of the rear plate 1c, and a stay 11 in the width direction is fixed slightly in front of the rear plate 1c so as to straddle the left and right side plates 1a, 1a. The stay 11 is provided with a flange-shaped stopper 11a that projects downward along its rear edge.

The support stand 20 that supports the glue box 1 has left and right front legs 21 that are in contact with the lower surface of the stopper 9 at the front, connecting these left and right front legs 21, 21, and a support base 20 that is made of pipes that are in contact with the lower surface of the stopper 9. Wallpaper cutting ruler 2
2. It is formed of left and right rear legs 23 that touch the lower surfaces of both ends of the rear stay 11, a horizontal stay 24 that connects the left and right rear legs 23, 23, a vertical stay 25 that connects the vicinity of the upper ends of the front and rear legs 21, 23, etc. The front, rear, left and right legs 21 and 23 and the wallpaper cutting ruler 2 are
Front stopper 9 and rear stay 1 are attached to the upper surface of 2.
The glue box 1 is detachably placed on the glue box 1 via the glue box 1.

Then, four U-shaped or J-shaped hooks 30 are removably hooked onto the upper edge of the front plate 1b of the glue box 1, and four vertically long protrusions are formed on the surface of the front plate 1b. Ru.

In the above structure, put the glue S in the glue box 1,
Holding rollers 4 and 5 are placed on standby upwards and wallpaper A is placed on the top surface of gluing roller 2 and leveling roller 6. Then, presser rollers 4 and 5 are lowered and wallpaper A is placed on gluing roller 2 and leveling roller 6. Press it onto the top surface of 6. Next, wallpaper A is pulled out by hand and glue S is applied to the back side of wallpaper A. After the desired length of wallpaper A is glued, the four hooks (protrusions) 30 are moved along the upper edge of the front board 1b. Then, align the cutting part of wallpaper A with the upper edge of the ruler 22, slide the knife 31 along the upper edge of the ruler 22, and cut the wallpaper A. do. This embodiment uses four hooks 3 for forming protrusions.
0 is provided removably, so the number of attachments can be selected according to the width and thickness of the wallpaper A, and the protrusions can be formed at optimal positions. Further, since it has a structure in which it is hooked onto the upper edge of the front plate 1b, it is easy to attach and detach it to a desired position, and it does not require a special storage space when not in use.

(Effects of the invention) According to this invention, when cutting the wallpaper, the back side of the wallpaper is prevented from coming into close contact with the front plate of the glue box, and a gap is formed between the wallpaper and the front plate, so that the thin wallpaper can be cut. Even when pasting, the cut wallpaper can be easily removed from the front board without damaging the wallpaper.
