When the gear adjusting mechanism 1 is adjusted, after the cutter is aligned and the dimension required to move downwards is calculated, the adjusting disk 49 at the upper end of the telescopic inner rod 45 is rotated, the corresponding number of turns of rotation is realized through the scale block on the adjusting disk 49 and the scale projection on the fixed sleeve 30, the adjusting disk 49 rotates to drive the telescopic inner rod 45 to rotate, the telescopic inner rod 45 rotates to drive the telescopic outer sleeve 46 to rotate through the matching of the guide block and the guide groove, the telescopic outer sleeve 46 rotates under the action of the thread because the telescopic outer sleeve 46 is in threaded fit with the thread surface 38 of the fixed sleeve 30, the telescopic outer sleeve 46 moves to drive the sliding sleeve 34 to move through the transmission ring 50 at the lower side, the sliding sleeve 34 moves to drive the mounting post 36 mounted at the lower side to slide through the pre-pressure of the return spring 35, the mounting post 36 slides to drive the blade mounting head 52 to move, the, so that the vertical cutting knife 27 is pressed against the outer layer of the wallpaper.

When the first roller 11 wound with the adhesive wallpaper 3 is installed, the pull rod 33 can be manually pulled upwards through the pull ring 28, the pull rod 33 drives the installation column 36 to move upwards, the installation column 36 moves upwards to drive the vertical cutting knife 27 on the lower side to move upwards, and the first roller 11 is prevented from interfering with the vertical cutting knife 27 in the installation process; meanwhile, in the invention, the mounting column 36 can be moved upwards by rotating the adjusting disc 49, so that the first roller 11 is prevented from interfering with the vertical cutting knife 27 in the mounting process.

When the tool is set, the height of the vertical cutting knife 27 is adjusted by rotating the adjusting disc 49, and the tool is set by observing scratches on the vertical cutting knife 27 and the outer layer adhesive sticker wallpaper 3.

The specific working process is as follows: when the cutting device designed by the invention is used, the first roller 11 wound with the self-adhesive wallpaper 3 is installed in the shell 5, during installation, the pull rod 33 is manually pulled upwards through the pull ring 28, the pull rod 33 drives the installation column 36 to move upwards, the installation column 36 moves upwards to drive the vertical cutting knife 27 on the lower side to move upwards, and the first roller 11 is prevented from interfering with the vertical cutting knife 27 in the installation process; then, the first roller 11 is fixed through the rotating shaft 16 and the screw 15, and the position of the positioning block 24 is also fixed during fixing; then, adjusting the gear adjusting mechanism 1 according to the width of the self-adhesive wallpaper 3 to be cut to enable the gear adjusting mechanism 1 to correspond to the width to be cut, and after the gear adjusting mechanism 1 is adjusted, positioning the gear adjusting mechanism 1 through the fixed disc 29; then, the height of the vertical cutting knife 27 is adjusted by rotating the adjusting disc 49, and the knife setting is carried out by observing scratches on the vertical cutting knife 27 and the outer layer adhesive sticker wallpaper 3; after the lower extreme of vertical cutting knife 27 and the outer zero distance contact of non-setting adhesive wall paper 3, after the tool setting is accomplished, just can cut, the method of cutting can divide into two kinds:

firstly, rotating the adjusting disc 49 according to the corresponding size of the existing adjusting disc 49 and the fixed sleeve 30, rotating the number of turns corresponding to the required cutting length according to calculation and experience, and compressing the return spring 35 when the adjusting disc 49 is continuously rotated so that the vertical cutting knife 27 is propped against the outer layer of the wallpaper; after the gear adjusting mechanism 1 finishes adjusting, the self-adhesive wallpaper 3 to be pulled out is pulled outwards, in the pulling process, the vertical cutting knife 27 gradually moves downwards under the action of the return spring 35 along with the cutting of the wallpaper, the inner layer of the self-adhesive wallpaper 3 is continuously cut, when the return spring 35 is completely released and returns to the initial prepressing state, the vertical cutting knife 27 stops moving downwards, the cutting length of the self-adhesive at the moment basically reaches the specified length, and the wallpaper on the self-adhesive can not be continuously cut even if the first roller 11 continues to rotate; the self-adhesive wallpaper 3 pulled out in the cutting process is pulled out from the upper side of the front end of the shell 5 through the guide of the two guide wheels, one end of the self-adhesive wallpaper 3 which is not required to be pulled out of the other part of the self-adhesive wallpaper 3 which is cut off is attached to the second roller 12, the second roller 12 is driven to rotate in the process of pulling out the self-adhesive wallpaper 3 which is required to be pulled out of the other part of the self-adhesive wallpaper which is not required to be pulled out of the self-adhesive wallpaper 3 which is cut off is wound on the second roller 12, and the situation that the part which is not required to be pulled out is polluted or wrinkled due to unfolding is prevented.

Secondly, after the size needing to move downwards is calculated, the adjusting disc 49 at the upper end of the telescopic inner rod 45 is rotated, the corresponding number of turns of rotation is realized through the scale block on the adjusting disc 49 and the scale bulge on the fixed sleeve 30, and when the adjusting disc 49 is rotated, the return spring 35 is compressed; after the adjustment is completed, the end part of the wallpaper on the first roller 11 is adhered to the first roller 11, the rocker 6 is rotated manually to drive the first roller 11 to rotate continuously for multiple circles, the self-adhesive wallpaper 3 to be cut is cut in the rotating process, and then the end part of the wallpaper is pulled out, so that the straightness of the cut self-adhesive wallpaper 3 can be ensured.

The transverse cutting mechanism 4 can flexibly and temporarily cut the required wallpaper, so that the length can be temporarily adjusted conveniently.

When the cutting length is adjusted, the required cutting length is rotated according to calculation and experience, the number of turns corresponding to the required cutting length is determined according to the cutting length and the number of turns wound on the first roller 11, certain errors exist between the cutting length and the required length, and the errors are within an acceptable range after the experience is accumulated through multiple times of use.
