As shown in fig. 2, 3 and 4, a shaft B15 parallel to the shaft a7 is rotatably fitted on a support B16 installed in the transmission groove a 2; a one-way ring A8 and a one-way ring B10 are coaxially arranged on the shaft A7, a belt wheel A9 is nested on the one-way ring A8, and a spur gear H11 is nested on the one-way ring A8; the belt pulley A9 is in transmission connection with a belt pulley B14 arranged on a shaft B15 through a synchronous belt A13; a shaft C21 is rotatably matched on a support C22 arranged in the transmission groove A2, and a straight gear I23 and a belt wheel C20 are coaxially arranged on the shaft C21; spur gear I23 is meshed with spur gear H11, and pulley C20 is in transmission connection with pulley D18 mounted on shaft B15 through synchronous belt B19.

According to the wallpaper cutting machine, the two rollers A6 in the transmission mechanism 5 are located between the corresponding blade 58 and the roller B31, and in the process of cutting wallpaper from top to bottom, the two rollers A6 in the transmission mechanism 5 roll on the wall surface along with the two rollers B31, so that the wallpaper is cut by the following blade 58 after being squeezed, flattened and spread by the rubber round sleeves 48 on the two rollers B31, the difficulty of aerial work is reduced, the wallpaper pasting quality is guaranteed, and wallpaper pasting in the aerial work is finished at one time.

In the invention, with the reduction of the indirect transmission ratio between the pulley A9 and the spur gear B24 or the indirect transmission ratio between the spur gear H11 and the spur gear B24, the rotation speed of the shaft E36 relative to the corresponding roller B31 and the rotation speed of the shaft E36 relative to the corresponding roller B31 tend to approach each other when the roller A6 or the roller B31 rotates in the forward direction and the rotation speed of the shaft E36 relative to the corresponding roller B31 when the roller A6 or the roller B31 rotates in the reverse direction, so that the speed of the bending and twisting motion of the three rubber circular sleeves 48 on the corresponding roller B31 driven by the shaft E36 through a series of transmissions when the roller A6 or the roller B31 rotates in the forward direction and the speed of the bending and twisting motion of the three rubber circular sleeves 48 on the corresponding roller B31 driven by the shaft E36 through a series of transmissions relative to the corresponding roller B31 approach each other speed when the roller A6 or the roller B31 rotates in the reverse direction, and further the rubber circular sleeves 48 on the two rollers B31 tend to approach the speed, the effect that wall paper on making indoor whole wall was pulled and is caught up with pressure is more even.

The working process of the invention is as follows: in the initial state, the blade 58 is hidden in the chute 3.

When the wall paper sticking to the wall surface is required to be cut at the corner of the wall surface by using the wall paper cutting machine, the right-angle seat 1 firstly supports against the right-angle corner on the wall surface, and two right-angle surfaces at the outer side of the right-angle seat 1 are respectively parallel to the wall surfaces at two sides of the corner of the wall surface, so that the right-angle position of the right-angle seat 1 is as close to the corner line of the wall surface as possible, the wall paper sticking to the wall surface is ensured to be fully bent at the corner line of the wall surface by the right-angle seat 1, and the wall paper is prevented from being suspended at. At the same time, it is ensured that the roller a6 and the roller B31 in the two transmission mechanisms 5 can make sufficient contact and interaction with the wall surface.

If the wallpaper is cut along the vertical wall corner line, the blade 58 is located on the upper portion of the right-angle seat 1 and above the roller B31 in the transmission mechanism 5, so that the blade 58 can cut off the uppermost end of the wallpaper as much as possible, secondary cutting operation on the upper end of the wallpaper in aerial operation on the herringbone ladder is avoided, cutting procedures are reduced, and cutting efficiency is improved.

The amount of feed of the blade 58 to the wall corner line is then adjusted so that the edge of the blade 58 interacts with the wallpaper to effect cutting of the wallpaper. The twisting wheel 61 is manually rotated, the twisting wheel 61 drives the screw 59 to rotate relative to the telescopic rod 52 in the sliding chute 3, the screw 59 pushes the telescopic rod 52 to move towards the direction of the corner line of the wall surface in the sliding chute 3 under the action of the internal thread sleeve 60 screwed with the screw 59, and the telescopic rod 52 simultaneously drives the blade 58 mounted at the tail end of the telescopic rod to move towards the wallpaper bending position at the corner line.

When the blade 58 meets the wallpaper, the torsion wheel 61 is continuously rotated, so that the telescopic rod 52 drives the blade 58 to continuously press the wallpaper, the telescopic rod 52 is compressed due to the continuous axial movement of the screw 59, the internal pressure spring 57 is further compressed to store energy, and the blade 58 is ensured to effectively cut the bending part of the wallpaper at the corner line in the subsequent movement process along the corner line of the wall surface. The feeding amount of the blade 58 to the wallpaper movement and the further compression amount of the telescopic rod 52 are determined according to the material and the thickness of the wallpaper, the harder and thicker the wallpaper material is, the larger the feeding amount of the blade 58 and the further compression amount of the telescopic rod 52 are, and the more effective cutting of the wallpaper by the blade 58 can be ensured. The softer and thinner the wallpaper material is, the smaller the feeding amount of the blade 58 and the further compression amount of the telescopic rod 52 are, so that the scratch of the wall surface caused by the transitional feeding of the blade 58 is avoided.

Then, the wall surface corner line is pushed to move from one end to the other end by holding the handle 4 with hands, and the blade 58 cuts the wallpaper from the bent part of the wallpaper at the wall surface corner along the movement of the wall surface corner line. In the cutting process of the blade 58 to the wallpaper, the interaction of the right-angle seat 1 and the right-angle corner of the wall surface plays a standard role of the ruler, so that the port of the wallpaper cut by the blade 58 is relatively straight, the wallpaper can be perfectly butted with the wallpaper on the wall surface on the other side of the corner of the wall surface, and the attractiveness of wallpaper pasting is improved.

Meanwhile, as the right-angle seat 1 moves along the direction of the corner line of the wall surface, the two rollers a6 and the two rollers B31 in the transmission mechanism 5 which are matched with the corresponding wall surface rotate. Because the same plane of the central axis of the shaft E36 and the central axis of the shaft A7 is parallel to the corresponding right-angle surface on the right-angle seat 1, and the outer diameter of a circular ring formed by the three rubber circular sleeves 48 on the roller B31 is equal to the outer diameter of the roller A6, the rotating speed of the two rollers A6 is equal to the rotating speed of the two rollers B31 in the same direction.

The two rotating rollers B31 each bring the corresponding cylinder 29 into synchronous rotation.

The two rollers A6 drive the inner ring of the coaxial one-way ring A8 and the inner ring of the one-way ring B10 to synchronously rotate through the shaft A7, and if the two rollers A6 are positioned in front of the two rollers B31 in the moving direction of the invention, the one-way ring A8 plays a one-way driving role at the moment, and the one-way ring B10 plays an overrunning role. The one-way ring A8 drives the shaft B15 to rotate in the same direction through the belt pulley A9, the synchronous belt A13 and the belt pulley B14, and the shaft B15 drives the belt pulley D18 and the straight gear A17 to rotate synchronously. The pulley D18 drives the outer ring of the one-way ring B10 to rotate relative to the inner ring thereof through a synchronous belt B19, a pulley C20, a shaft C21, a spur gear I23 and a spur gear H11, and the rotation direction of the inner ring and the rotation direction of the outer ring of the one-way ring B10 are opposite. Meanwhile, the spur gear A17 drives the corresponding shaft D25 to rotate through a spur gear B24, the shaft D25 drives the belt wheel E50 and the bevel gear A27 which are installed on the shaft D25 to rotate synchronously, and the rotation direction of the shaft D25 is opposite to that of the roller B31. The bevel gear A27 drives the bevel gear C37 to rotate through two bevel gears B28 meshed with the bevel gear A27. Since the transmission ratio of the pulley a9 to the pulley B14 is 1: 2, the transmission ratio of the spur gear H11 to the spur gear I23 is 1: 2, the transmission ratio of the belt wheel C20 to the belt wheel D18 is 1: 1, the transmission ratio of the spur gear A17 to the spur gear B24 is 1: 2, the bevel gear C37 rotates the corresponding shaft E36 in the opposite direction of the rotation of the roller B31. The shaft E36 drives the three straight gears D39 to rotate through a straight gear C38, the three straight gears D39 drive corresponding shafts F46 to rotate through corresponding straight gears E40, shaft sleeves 41, bevel gears D42, bevel gears E43, straight gears F44 and straight gears G45 respectively, the three shafts F46 drive three rubber circular sleeves 48 to perform bending and twisting motion relative to a roller B31 through three transmission shafts 49, and the three rubber circular sleeves 48 on the rim of the roller B31 pull and crush wallpaper which is extruded by the three rubber circular sleeves 48 towards the corner line direction of the wall surface. Meanwhile, the shaft D25, to which the spur gear B24 is attached, rotates the other shaft D25 of the transmission 5 at a constant speed in the same direction by the pulley E50, the timing belt C51, and the other pulley E50 attached thereto. The other shaft D25 in the transmission mechanism 5 drives the three rubber round sleeves 48 of the corresponding roller B31 to do bending and twisting motion relative to the corresponding roller B31 through a series of transmission, and the wallpaper on the wall is pulled and pressed towards the corner line direction of the wall.

If two rollers a6 are located behind two rollers B31 in the direction of motion of the present invention, then one-way loop A8 now provides an overrunning action and one-way loop B10 provides a one-way driving action. One-way ring B10 drives shaft B15 to rotate through spur gear H11, spur gear I23, shaft C21, belt pulley C20, synchronous belt B19 and belt pulley D18, and shaft B15 drives belt pulley B14 and spur gear A17 to rotate synchronously. The pulley B14 drives the outer ring of the one-way ring A8 to rotate relative to the inner ring thereof through the synchronous belt A13, the pulley A9 and the shaft A7, and the rotation direction of the inner ring and the outer ring of the one-way ring A8 is opposite. Meanwhile, the spur gear a17 drives the corresponding shaft D25 to rotate through the spur gear B24, the shaft D25 drives the pulley E50 and the bevel gear a27 mounted thereon to rotate synchronously, and the rotation direction of the shaft D25 is kept unchanged and at the same time the rotation direction of the roller a6 or the roller B31 is the same. The bevel gear A27 drives the bevel gear C37 to rotate through two bevel gears B28 meshed with the bevel gear A27. The bevel gear C37 drives the corresponding shaft E36 to rotate at the same direction which is several times of the rotating speed of the roller A6 or the roller B31, and the rotating direction of the rotating shaft E36 relative to the corresponding roller B31 is unchanged. The shaft E36 drives the three straight gears D39 to rotate through a straight gear C38, the three straight gears D39 drive corresponding shafts F46 to rotate through corresponding straight gears E40, shaft sleeves 41, bevel gears D42, bevel gears E43, straight gears F44 and straight gears G45 respectively, the three shafts F46 drive three rubber circular sleeves 48 to perform bending and twisting motion relative to a roller B31 through three transmission shafts 49, and the three rubber circular sleeves 48 on the rim of the roller B31 pull and crush wallpaper which is extruded by the three rubber circular sleeves 48 towards the corner line direction of the wall surface. Meanwhile, the shaft D25, to which the spur gear B24 is attached, rotates the other shaft D25 of the transmission 5 at a constant speed in the same direction by the pulley E50, the timing belt C51, and the other pulley E50 attached thereto. The other shaft D25 in the transmission mechanism 5 drives the three rubber round sleeves 48 of the corresponding roller B31 to do bending and twisting motion relative to the corresponding roller B31 through a series of transmission, and the wallpaper on the wall is pulled and pressed towards the corner line direction of the wall.

When the two rollers a6 are forward of the two rollers B31 in the direction of motion of the present invention, the axis E36 rotates in the opposite direction to the roller a6 or roller B31.

When the two rollers a6 are located behind the two rollers B31 in the direction of motion of the present invention, the direction of rotation of the axis E36 is the same as the direction of rotation of the roller B31 or the roller a6, since the direction of rotation of the axis E36 is unchanged.

No matter the roller B31 or the roller A6 rotates forwards or backwards, the rotating direction of the shaft E36 relative to the corresponding roller B31 is unchanged, so that the shaft E36 drives the three rubber round sleeves 48 on the corresponding roller B31 to pull and press wallpaper interacted with the shaft towards the corner line direction of the wall surface all the time through a series of transmission, bulges or folds of the wallpaper pasted on the wall surface are pulled and flattened in the wallpaper cutting process, and the wallpaper pasting effect is more attractive.

After the use of the invention is finished, by reversely rotating the torsion wheel 61, the torsion wheel 61 can be stored in the chute 3 again through a series of driving belt moving blades 58. In the cutting process of the blade 58 for wallpaper, the screw 59 and the internal thread sleeve 60 are matched in thread to have a self-locking function, so that the blade 58 cannot retract under the reverse action of wallpaper or wall surface, and the effective cutting of the blade 58 for wallpaper is guaranteed.

In conclusion, the beneficial effects of the invention are as follows: according to the invention, the rubber round sleeves 48 on the rims of the rollers B31 in the two transmission mechanisms 5 are used for driving the wallpaper on the wall surface to the corner line direction of the wall surface corner relative to the directional bending and twisting of the rollers B31, so that the bulges are pulled to be leveled after the pressure-sensitive adhesive wallpaper pre-adhered to the wall surface has wrinkles, and the redundant wallpaper moves to the other wall surface through the corner of the wall surface, thereby ensuring the flatness and construction quality of the wallpaper adhered to the wall surface. The wallpaper is then cut by the blade 58 along the wall corner line from the wall corner line. Due to the fact that the right-angle structure of the right-angle seat 1 is adopted, the blades 58 can cut the wallpaper at the corner line of the wall surface without the assistance of tools such as straight teeth and the like, so that the wallpaper can be cut linearly, the flatness of a cut of the wallpaper is guaranteed, butt joint of the wallpaper on the wall surfaces on two sides of the corner is facilitated, the attractiveness of wallpaper pasting is improved, and the wallpaper cutting efficiency is improved.

When the cutting knife is used, the blade stretches out to cut when moving from top to bottom, and the blade retracts to only flatten when moving from bottom to top.

Meanwhile, as the wallpaper cutting process does not need to use auxiliary tools such as straight teeth and the like, the wallpaper pasting operation procedure is simpler for an operator who works in the air on the herringbone ladder, so that the safety of the worker who works in the air in the work process is effectively improved.
