Description

[0001]
[Industrial application fields]
The present invention relates to a slitter for wallpaper. More specifically, the present invention relates to a wallpaper slitter for width adjustment when pasting on a wall or ceiling.
[0002]
[Prior art and its problems]
Conventionally, in wallpaper pasting and pasting work, it is necessary to adjust the width to adjust the wallpaper to the required width, so slitters have been used to cut out both sides of the wallpaper and adjust the width. ing.
Various types of wallpaper slitters have been developed and put to practical use so far, and a typical one shown in FIG. 8 is known.
[0003]
That is, it has an upper blade (1) and a lower blade (2) whose axial centers are substantially parallel to each other, and the upper blade (1) and the lower blade (2) are pressed against each other on both sides in the wallpaper feeding direction. The rotating shaft (3) of the lower blade (2) is provided with a guide roller (4), and the rotating shaft (3) is supported by the lower blade fixing stay (7) by the bracket (5). Yes. A pressing roller (6) is disposed in the vicinity of the lower blade (2), and the upper blade (1) is mounted on the support shafts (12) and (13). Furthermore, an upper blade fixing stay (8), a cutter seal (9), and a scale plate (10) are disposed in the slitter. The rotating shaft (3) of the lower blade (2) is rotationally driven by the drive connecting gear (11).
[0004]
In this conventional wallpaper slitter, the upper blade (1) and the lower blade (2) are pressed against each other by a spring interposed between the pressing roller (6) and the lower blade (2), and the upper blade (1) and the lower blade (2) are pressed. The slit width is variable by changing the position of the blade (2).
However, in the case of the conventional wallpaper slitter having the configuration as described above, since the cutting of the wallpaper cloth is usually performed to the extent of cutting the edge of the wallpaper cloth, it is not necessary to move the cutter so much, so the support shaft of the upper blade (1) (12) and (13) are different. For this reason, there has been a problem that when the width alignment size of the wallpaper is large, it cannot be cut at a time.
[0005]
This is because wallpaper is generally applied in the vertical direction, but in some cases it may be applied in the horizontal direction. In such a case, it is necessary to cut it to a width of about 300 to 400 mm depending on the height to the ceiling. This is because it had to be cut manually before or after gluing, which was very troublesome.
Even if the support shafts (12) and (13) of the upper blade (1) are lengthened, the conventional slitter has the guide roller (4) for preventing the deflection of the wallpaper. It was actually difficult to move a lot.
[0006]
Therefore, the present invention has been made in view of the circumstances as described above, eliminates the drawbacks of the conventional wallpaper slitter, can be cut even at a large width at a time, and effectively suppresses the deflection of the wallpaper. It aims to provide a new wallpaper slitter that is possible.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention has an upper blade and a lower blade in which the shaft centers of the mounting shafts that are vertically opposed to each other are substantially parallel to each other, and are respectively mounted on both sides of the same shaft so that the mutual width interval can be adjusted. In the slitter for wallpaper, which has a blade and the upper blade and the lower blade are pressed against each other in both directions in the feeding direction of the wallpaper, the rotation axis of the lower blade is movable and / or detachable to prevent deflection of the wallpaper. Provided is a wallpaper slitter characterized in that a guide roller as a wallpaper guide is arranged.
[0008]
[Action]
In the wallpaper slitter of the present invention, as described above, since the upper blade and the lower blade are attached to both sides of the same shaft, the position adjustment is easy, and the width is, for example, about 300 mm to 400 mm. However, this can be cut at once, and the troublesome work of cutting manually is not required at all. Moreover, because the wallpaper guide that can be moved and removed is arranged, even when cutting to a large width, this wallpaper guide can be arranged appropriately, so even when the wallpaper is pulled and sent to the gluing machine, Tension can be given to the wallpaper, and the occurrence of wrinkles due to the deflection of the wallpaper can be suppressed.

【Example】
Hereinafter, examples will be described with reference to the drawings, and the wallpaper slitter of the present invention will be described more specifically.
FIG. 1 of the accompanying drawings is a perspective view illustrating a wallpaper slitter of the present invention.
For example, as illustrated in FIG. 1, in the wallpaper slitter (20) of the present invention, the upper blade (21) and the lower blade (22) whose axis centers are substantially parallel to each other are pressed against both sides of the wallpaper feeding direction. The upper blade (21) is attached to the upper blade shaft (25), and the lower blade (22) is attached to the lower blade shaft (23). The lower blade shaft (23) is provided with a plurality of wallpaper guide rollers (24) that can be moved left and right.
[0010]
By using this movable wallpaper guide roller (24), even if the width to be cut is about 300 mm to 400 mm, the wallpaper can be held by moving the wallpaper guide roller (24). Of course, the movement adjustment of the upper blade (21) and the lower blade (22) is also easy.
This wallpaper guide roller (24) is indispensable, and without it, the wallpaper will bend and the wallpaper will meander and be cut.
[0011]
FIGS. 2A and 2B are a cross-sectional view and a perspective view showing an example in which a wallpaper guide roller that can expand and contract by a combination of rollers is configured. A roller (31) having a small diameter is disposed in the center, and rollers (32) having hollow portions having an inner diameter larger than the diameter are disposed on both sides thereof. By moving the left and right rollers (32) having the hollow portion to the left and right, and also allowing the small diameter roller (31) to move, it becomes easy to expand and contract the width of the entire roller.
[0012]
FIG. 3 is a cross-sectional view illustrating the structure of a telescopic guide roller having a bellows structure. The bellows (33) is used as a mechanism for expanding and contracting.
FIG. 4 is a cross-sectional view showing the structure of a telescopic guide roller having a coil spring structure. A coil spring (34) is used as a mechanism for expanding and contracting.
5A and 5B are a perspective view and a cross-sectional view showing the structure of a wallpaper guide roller that can be divided and removed. As shown in FIG. 5 (a), the divided portions (35) and (36) are fastened with screws (37) at four locations, and as shown in FIG. 5 (b), a rotating hinge portion (38) is provided and provided at two locations. Can be stopped with a screw (37). By attaching the divided portions (35) and (36) to the required positions of the lower blade shaft (23), sagging of the wallpaper can be prevented and cutting at both sides of the movement becomes possible.
[0013]
FIGS. 6A and 6B are a cross-sectional view and a perspective view illustrating a plug-in type wallpaper guide stay (40) that is movable and removable. One or more wallpaper guide stays (40) of this example are appropriately disposed between the lower blades (22) on both sides. In this case, for example, the insertion groove (42) can be fitted to the support bar (41), or the insertion can be freely performed as the reverse relationship. By changing the insertion position, the wallpaper guide stay (40) can be moved. The wallpaper (60) is sent out along the upper surface of the guide stay (40).
[0014]
FIGS. 7A and 7B are a cross-sectional view and a partial perspective view illustrating a wallpaper guide stay (50) having another structure. In this example, it couple | bonds with a volt | bolt (53) via a long hole (52) with respect to a support part (51).
The stay (50) is also mounted and moved using the elongated hole (52).
[0015]
【The invention's effect】
With the wallpaper slitter of the present invention, as described in detail above, even if there is a large change in dimension width, it can be cut at once, and the deflection of the wallpaper can be effectively suppressed.
