The embodiment of the application provides a cutting device, it can improve the wall paper cutting device among the prior art and cut the in-process unstability in the overlapping region to the wall paper to lead to the overlapping region's of wall paper to cut the quality relatively poor, and then be unfavorable for the problem of the shop's of wall paper subsides, the following concrete structure that combines the attached drawing to describe in detail cutting device.

As shown in fig. 1 and 2, the cutting apparatus 100 includes a cutting module 10 and a pressing module 20. The cutting module 10 includes a cutter 11, and the cutter 11 is configured to cut the overlapping area 200 along a second direction Y, so as to form a cutting seam extending along the second direction Y in the overlapping area 200, where the second direction Y is perpendicular to the first direction X and is parallel to the wall surface 300. The pressing module 20 includes a pressing member 21, the pressing member 21 is located on a first side of the cutting knife 11 in the first direction X, the pressing member 21 is configured to abut against a portion of the overlapping area 200 located on the first side of the cutting seam in the first direction X along a third direction Z toward the wall surface 300 in the process that the cutting knife 11 cuts the overlapping area 200, and the third direction Z is perpendicular to the wall surface 300.

The cutting module 10 is provided with a cutter 11, and the cutter 11 is used for cutting the overlapping area 200 of the wallpaper 400 along the second direction Y to cut the redundant wallpaper 400 in the overlapping area 200, so as to facilitate the tiling of the wallpaper 400, and to enable the seam between every two adjacent wallpapers 400 tiled on the wall surface 300 to be flat. Wherein, when the cutter 11 cuts overlapping area 200, because the wall paper 400 is still in the not firm state of pasting, the direction butt in overlapping area 200 that can follow perpendicular to wall 300 through the piece 21 that compresses tightly of module 20, thereby play to the wall paper 400 of overlapping area 200 and compress tightly and firm effect, be convenient for the cutter 11 to cut overlapping area 200's wall paper 400, in order to reduce the phenomenon that the wall paper 400 drunkenness appears at the in-process of cutting, and then can improve the stability of cutter 11 at the in-process that cuts, be favorable to improving the quality of cutting of wall paper 400. In addition, by arranging the pressing piece 21 on the first side of the cutting knife 11 in the first direction X, the pressing piece 21 can abut against the part, located on the first side, of the overlapping area 200 in the first direction X in the process that the cutting knife 11 cuts the overlapping area 200, that is, in the process that the cutting knife 11 cuts the overlapping area 200, the pressing piece 21 can press and stabilize the wallpaper 400, located on the first side of the cutting knife 11 in the first direction X, of the overlapping area 200, and the pressing piece 21 can press the wallpaper 400 being cut by the cutting knife 11, so that the cutting device 100 adopting the structure is beneficial to further reducing the risk that the wallpaper 400 moves or slides in the cutting process, and further improving the stability of the cutting device 100 when cutting the overlapping area 200 of the wallpaper 400 and the cutting quality of the wallpaper 400.

As shown in fig. 2 and 3, the wallpaper 400 is sequentially laid on the wall surface 300 along the first direction X, so as to form an overlapping area 200 between every two adjacent wallpapers 400, and the cutter 11 is configured to cut the overlapping area 200 along the second direction Y, so as to cut off the extra wallpaper 400 in the overlapping area 200, thereby facilitating the wallpaper 400 to be smoothly laid on the wall surface 300.

It should be noted that, the first direction X is a paving direction in which the wallpaper 400 is sequentially paved on the wall surface 300, the second direction Y is a traveling direction in which the cutter 11 cuts the wallpaper 400 in the overlapping area 200, a first side of the cutter 11 in the first direction X is a side of the cutter 11 in a forward direction of the paving direction of the wallpaper 400, that is, the pressing member 21 is pressed on the wallpaper 400 exposed outside the overlapping area 200, and the first direction X, the second direction Y and the third direction Z are mutually perpendicular in pairs.

Further, the pressing range of the pressing member 21 in the first direction X exceeds the edge of the wallpaper 400 covered on the inner side by the overlapping area 200 in the first direction X. The pressing range of the pressing piece 21 in the first direction X is set to exceed the edge of the wallpaper 400 inside the overlapping area 200, that is, the edge of the wallpaper 400 inside the overlapping area 200 and the wallpaper 400 outside the overlapping area are attached to form a cavity 500 (see fig. 3), the cavity 500 is formed by attaching the edge part of the wallpaper 400 outside the overlapping area 200 to the wallpaper 400 inside the overlapping area 400, and the rest part of the wallpaper 400 outside the overlapping area 300 is attached to the wall surface 300, so that a step difference is formed, and the pressing range of the pressing piece 21 in the first direction X exceeds the edge of the wallpaper 400 inside the overlapping area 200, so that the pressing piece 21 can press the cavity 500 part while pressing the overlapping area 200, which is beneficial to better attaching the wallpaper 400 to the wall surface 300, and improves the attaching quality of the wallpaper 400.

In this embodiment, as shown in fig. 1 and 4, the cutting device 100 further includes a base plate mechanism 30, a driving mechanism 40, and a sliding mechanism 50. The base mechanism 30 is used to be mounted on the work frame. Actuating mechanism 40 and slide mechanism 50 all install on bottom plate mechanism 30, cut module 10 and compress tightly module 20 and all connect in slide mechanism 50, and actuating mechanism 40 is used for driving slide mechanism 50 and removes along third direction Z relative bottom plate mechanism 30, and wall 300 is kept away from to the positive orientation of third direction Z towards wall 300, third direction Z's the reverse. When the cutting knife 11 cuts the overlapped area 200, the driving mechanism 40 drives the sliding mechanism 50 to move and drive the cutting module 10 and the pressing module 20 to move in the forward direction of the third direction Z, so that the cutting knife 11 pierces through the wallpaper 400 in the overlapped area 200, and the pressing piece 21 presses the wallpaper 400 exposed outside the overlapped area 200 onto the wall surface 300. The specific structure of the bottom plate mechanism 30 can be found in the related art, and is not described in detail herein.

The cutting device 100 is provided with a bottom plate mechanism 30, a driving mechanism 40 and a sliding mechanism 50, the driving mechanism 40 and the sliding mechanism 50 are both installed on an operation frame body of the wallpaper paving and pasting robot through the bottom plate mechanism 30, the cutting module 10 and the pressing module 20 are both installed on the sliding mechanism 50, the driving mechanism 40 can drive the sliding mechanism 50 to move along the third direction Z relative to the bottom plate mechanism 30, so that the cutting module 10 and the pressing module 20 are driven to move in the third direction Z, the cutting module 10 and the pressing module 20 can cut and press wallpaper 400 in an overlapped area 200, automatic cutting of the wallpaper 400 is achieved, the structure is simple, implementation is convenient, and control over the cutting depth of the cutter 11 and the pressing force of the pressing piece 21 is facilitated.

Wherein the driving mechanism 40 drives the sliding mechanism 50 to move with a constant force. When the cutter 11 cuts the overlapped area 200, the reaction force of the wall surface 300 to the cutter 11 and the pressing member 21 is defined as a first force. When the first acting force is smaller than the constant force of the driving mechanism 40, the driving mechanism 40 drives the cutting module 10 to approach the wall surface 300. When the first acting force is larger than the constant force of the driving mechanism 40, the driving mechanism 40 drives the cutting module 10 away from the wall surface 300.

By setting the driving force of the driving mechanism 40 driving the sliding mechanism to move along the third direction Z to be a constant force equal to the sum of the reaction forces of the overlapping area 200 to the cutter 11 and the pressing member 21, when the first acting force is smaller than or greater than the constant force of the driving mechanism 40, the driving mechanism 40 can correspondingly drive the cutting module 10 and the pressing module 20 to approach or depart from the wall surface 300, that is, in the process of cutting the wallpaper 400 in the overlapping area 200, the cutting device 100 adopting such a structure can adjust the cutting depth of the cutter 11 to the wallpaper 400 according to the shape of the wall surface 300, so as to avoid the phenomenon that the cutter 11 does not cut the wallpaper 400 in place or scratches the wall surface 300, for example, when a concave part appears on the wall surface 300 and the wallpaper 400 can follow the concave part of the wall surface 300 on the path of the cutter 11 cutting along the second direction Y, because the wall surface 300 is concave, the reaction force of the wall surface 300 to the cutter 11 can be suddenly reduced, so that the reaction force of the overlapped area 200 to the pressing piece 21 can be suddenly reduced, at the moment, the driving mechanism 40 can drive the cutting module 10 and the pressing module 20 to move along the third direction Z towards the direction close to the wall surface 300, so that the cutter 11 can be ensured to cut the wallpaper 400 in place, the same is also realized, when the protruded part appears on the wall surface 300, the wallpaper 400 of the overlapped area 200 can protrude outwards, so that the reaction force of the overlapped area 200 to the cutter 11 and the pressing piece 21 can be suddenly increased, at the moment, the driving mechanism 40 can drive the cutting module 10 and the pressing module 20 to move along the third direction Z towards the direction far away from the wall surface 300, and the cutter 11 can be prevented from scratching the wall surface 300. Meanwhile, when a pre-formed hole groove such as a socket opening appears on the cutting path of the cutting knife 11 along the second direction Y, because the back side of the partial overlapping area 200 is a hollow space, when the cutting knife 11 cuts the partial wallpaper 400, the driving mechanism 40 can drive the cutting module 10 and the pressing module 20 to move along the third direction Z toward the direction close to the wall surface 300, even if the partial wallpaper 400 retracts into the hollow space due to the acting force of the cutting knife 11, the cutting knife 11 can still pierce and cut the partial wallpaper 400 along the third direction Z toward the direction close to the wall surface 300, at this time, the pressing module 20 abuts against the wallpaper 400 on the outer side, and due to the characteristic that the pressing module 20 is adaptive to abut against the overlapping area 200, the pressing module 20 always abuts against the wallpaper 400 exposed on the outer side, and the play of the wallpaper 400 is suppressed.

Further, the cutting module 10 further includes a tool post 12, the tool post 12 is fixedly connected to the sliding mechanism 50, the cutting knife 11 is rotatably connected to the tool post 12, and the rotation axis of the cutting knife 11 is parallel to the first direction X.

The mount 22 is connected to the slide mechanism 50, and the pressing member 21 is movably provided in the mount 22 in the third direction Z. When the driving mechanism 40 drives the cutting module 10 to move so that the cutting knife 11 pierces through the wallpaper 400 in the overlapping area 200 along the forward direction of the third direction Z, the pressing member 21 can move along the reverse direction of the third direction Z to be in self-adaptive contact with the wallpaper 400 exposed outside the overlapping area 200.

The mounting seat 22 and the cutting module 10 are both mounted on the sliding mechanism 50, the pressing piece 21 of the pressing module 20 is movably mounted on the mounting seat 22 along the third direction Z, so that the pressing piece 21 floats on the mounting seat 22, the driving mechanism 40 drives the sliding mechanism 50 to move along the third direction Z, and the driving knife 11 is driven to pierce through the wallpaper 400 of the overlapping area 200, the pressing piece 21 can move along the third direction Z in the opposite direction relative to the mounting seat 22, and is self-adaptively pressed on the overlapping area 200, the cutting device 100 adopting the structure avoids the pressing piece 21 from limiting the cutting depth of the cutting knife 11 to the wallpaper 400, so that the cutting depth of the cutting knife 11 to the wallpaper 400 is conveniently adjusted according to the actual construction environment, different construction working conditions are adapted, and the use range and flexibility of the cutting device 100 are favorably improved.

When the wallpaper 400 in the overlapping area 200 is cut by the cutting knife 11 along the second direction Y, the upstream intersection 112 and the downstream intersection 113 are formed by the projection of the cutting knife 11 and the wallpaper 400 in the overlapping area 200 in the first direction X, and the downstream intersection 113 does not exceed the downstream pressing position 2122 in the second direction Y, that is, the cutting knife 11 travels along the second direction Y, and the wallpaper 400 in the overlapping area 200 is cut by the cutting knife 11, so that the cutting point of the wallpaper 400 by the cutting knife 11 does not exceed the downstream pressing position 2122 in the traveling direction of the cutting knife 11, and the phenomenon that the wallpaper 400 at the non-pressing part is cut by the cutting knife 11 can be avoided, and further, the risk that the wallpaper 400 is wrinkled or wavy edges occurs when the wallpaper 400 is cut by the cutting knife 11 along the second direction Y can be reduced, so as to improve the cutting smoothness of the wallpaper 400.

It should be noted that the upstream pressing position 2121 and the downstream pressing position 2122 are arranged in the second direction Y, the front end point 111 of the cutting blade 11 is located between the upstream pressing position 2121 and the downstream pressing position 2122, that is, the upstream pressing position 2121 and the downstream pressing position 2122 are arranged in the traveling direction of the cutting blade 11, the downstream pressing position 2122 is located on a portion of the overlapping region 200 that is not cut in the second direction Y, and the upstream pressing position 2121 is located on a portion of the overlapping region 200 that is cut in the second direction Y.

In this embodiment, as shown in fig. 1, 6 and 10, the pressing module 20 further includes an elastic member 24, and the elastic member 24 is disposed on a side of the pressing member 21 departing from the wall surface 300 in the third direction Z. When the cutter 11 does not cut the overlapped area 200, the pressing piece 21 exceeds the foremost end of the cutter 11 in the third direction Z toward the wall surface 300 (see fig. 7). When the cutter 11 cuts the overlapped area 200, the pressing member 21 compresses the elastic member 24 and retracts to the foremost end of the cutter 11 in the third direction Z toward the wall surface 300 (see fig. 8).

Through set up the elastic component 24 on the side that deviates from wall 300 in third direction Z at compressing member 21, make compressing member 21 can compress elastic component 24 after butt in overlap region 200, so that compressing member 21 contracts to the rear side of the front end point 111 of cutter 11 from the front side of the front end point 111 of cutter 11 on third direction Z, thereby realize compressing member 21 compresses tightly the wall paper 400 of overlap region 200 when cutter 11 cuts the wall paper 400 of overlap region 200, and then realized compressing member 21's floating and compressing effect, cutting device 100 who adopts this kind of structure has avoided compressing member 21 and overlap region 200's wall paper 400 to carry out rigid contact when improving compressing member 21 to overlap region 200's compressing effect, thereby can reduce compressing member 21 and damage the risk of wall paper 400. In addition, when the pressing member 21 abuts against the overlapping area 200, the pressing member 21 retracts from the front side of the foremost end of the cutting knife 11 to the rear side of the foremost end of the cutting knife 11 in the third direction Z, so that the displacement of the pressing member 21 is effectively increased, the compression amount of the elastic member 24 is increased, the acting force of the elastic member 24 on the pressing member 21 in the direction towards the wall surface 300 in the third direction Z is increased, the pressing force of the pressing member 21 on the overlapping area 200 is increased, and the pressing effect of the pressing member 21 is improved.

As shown in fig. 8 and 10, the distance between the pressing member 21 and the front end of the cutting knife 11 is equal to the distance between the outer surface of the wallpaper 400 exposed outside of the overlapping area 200 and the wall surface 300. The distance of the pressing piece 21, which is retracted from the front end point 111 of the cutting knife 11 in the third direction Z, is set to be equal to the thickness of the wallpaper 400 in the overlapping area 200, so that the cutting depth of the cutting knife 11 to the wallpaper 400 is equal to the thickness of the wallpaper 400 in the overlapping area 200 when the pressing piece 21 presses the wallpaper 400 in the overlapping area 200, and the cutting knife 11 can be prevented from scratching the wall surface 300 in the overlapping area 200 when the wallpaper 400 is cut. Furthermore, when the cutting knife 11 cuts the overlapped area 200, it is defined that the distance of the pressing member 21 retracted from the foremost end of the cutting knife 11 is equal to the thickness of the overlapped area 200, that is, the thickness of the two wallpaper 400, which is the average value, so that the compression amount of the elastic member 24 at the back side can be kept constant during the process that the cutting knife 11 cuts the overlapped area 200, thereby being beneficial to keeping the pressing force of the pressing member 21 constant.

As can be seen in fig. 10, the two wallpapers 400 in the overlapping region 200 are overlapped by a thickness d, the compression amount of the elastic member 24 is L1 before the pressing member 21 abuts against the overlapping region 200, when the cutting knife 11 cuts the wallpaper 400 in the overlapping region 200, the pressing member 21 is retracted from the front side of the foremost end of the cutting knife 11 to the rear side of the foremost end of the cutting knife 11 in the third direction Z, at this time, the compression amount of the elastic member 24 is L2, and since the distance that the pressing member 21 is retracted from the foremost end of the cutting knife 11 is equal to the distance between the outer surface of the wallpaper 400 exposed outside the overlapping region 200 and the wall 300, the difference between the L2 and the wall surface d and the L1 is always a constant value.
