The inner ring is connected with the screw rod 3 through threads, the limiting block 8 limits the sliding cutter disc 4, the sliding cutter disc 4 is prevented from rotating along with the screw rod 3, the screw rod 3 can horizontally slide on the sliding groove 13 and the cutter shaft 2 with the sliding cutter disc 4 when rotating, and the sliding cutter disc 4 can horizontally slide on the outer side of the cutter shaft 2 under the action of the threads when the screw rod 3 rotates, so that the distance between the sliding cutter disc 4 and the fixed cutter disc 41 is changed, the adjustment of the distance between the adjacent cutter disc and the cutter blade 5 is realized, and the sliding cutter is used for cutting adhesive tape products or semi-finished adhesive tapes with different widths.

And when the cutter shaft 2 rotates, the sliding cutter head 4 also rotates along with the cutter shaft 2 under the limiting action of the limiting block 8.

A rotating hole is formed in the cutter shaft 2 and is used for rotating the screw rod 3. As shown in fig. 2, an opening structure is provided at one end of the cutter shaft 2, and the screw rod 3 just extends into the opening, and the opening serves as a rotating hole for rotating the screw rod 3. When the screw rod 3 is rotated, the screw rod 3 is pinched by fingers or pliers, and the screw rod 3 is rotated, so that the screw rod 3 can be rotated, and the position of the sliding cutter 4 is adjusted.

The rotation of the screw 3 can be achieved as well.

Since the above structure can only adjust the distance between the sliding cutterhead 4 and the fixed cutterhead 41 during adjustment, the distance between the adjacent cutterheads will not be uniform because the sliding cutterhead 4 slides later during adjustment, and the distance between the cutterheads will be in a large-small cross distribution.

Therefore, in a further embodiment, in order to better realize the adjustment between adjacent cutterheads, the distance between the cutterheads is uniform, so that adhesive tape products with different distances can be cut, and the problem that the existing cutter cannot adjust the distance between the adjacent cutterheads and cannot realize the adjustment of the cutter is solved.

The outside of every section lead screw all installs inner ring and slip blade disc 4 through the screw thread, and slip blade disc 4 then installs in the outside of axle section, rotates every section lead screw, and slip blade disc 4 can be on the axle section horizontal slip, adjusts the position of slip blade disc 4 on the axle section.

When the position between the adjacent cutterheads is adjusted, the screw rod on the shaft section can be rotated by hand, the screw rod slides on the shaft section with the sliding cutterhead 4, so that the position of the sliding cutterhead on the shaft section is adjusted to a proper position (the distance between the sliding cutterhead 4 which is installed in advance is the distance to be cut), and then the shaft section is installed together by bolts to form the cutter shaft 2. The connecting shaft 11 and the connecting hole between each section of screw rods are spliced together, and as the adjacent sections of screw rods are not connected together after each section of screw rods are connected into a whole, the screw rods cannot rotate together, the screw rods do not need to be rotated after each section of screw rods are connected together to adjust the position between the sliding cutter heads, and under the action of the limiting block 8, the sliding cutter heads 4 can rotate together along with the cutter shafts 2, so that the cutting of the adhesive tape paper tube or the semi-finished product is realized. In this embodiment, the end of the last cutter shaft 2, which is not connected, is in an opening structure.

In a further embodiment, the open end of the arbor 2 is screw-mounted with a sealing disc 15. When the sealing disc 15 is installed with the cutter shaft 2, the opening side of the cutter shaft 2 is sealed, and the opening side of the cutter shaft 2 is protected. When the sealing disc 15 and the cutter shaft 2 are installed together, the screw rod 3 just stretches into the sealing disc 15 and is rotationally connected with the sealing disc 15, so that the end part of the screw rod 3 can be supported, and the screw rod 3 is placed more stably.
