This invention relates to the field of slitting machine technology, and in particular discloses an intelligent slitting and tape-sealing device for roll materials. The device includes a slitting machine, a slitting assembly mounted on the slitting machine for slitting externally unrolled roll materials, and a first frame for carrying the external roll materials. It also includes a cutting mechanism for cutting the unrolled roll materials, a rolling mechanism, and a tape-sealing mechanism used in conjunction with the cutting mechanism. By integrating the slitting, cutting, rolling, and tape-sealing mechanisms, the device achieves automatic slitting, cutting, winding, and tape-sealing of the unrolled roll materials, greatly improving production efficiency and automation. The slitting and cutting mechanisms used in conjunction enable precise slitting and cutting of the unrolled roll materials, ensuring accurate dimensions of the processed small roll materials. The tape-sealing mechanism compresses and cuts the tape, ensuring that the tape adheres to the roll material and seals it, providing a high-quality sealing effect and improving roll material production efficiency.

This utility model discloses a lockable sliding switch, comprising: an upper shell and a lower shell, the upper shell and the lower shell being connected to form a closed outer shell structure; a rotary lock seat, rotatably disposed within the upper shell and the lower shell; and a fixed lock seat, fixedly disposed within the upper shell and the lower shell, forming a relative rotational relationship with the rotary lock seat; the rotary lock seat is provided with a first locking plate, and the fixed lock seat is provided with a second locking plate; when the rotary lock seat is rotated to the locked position, the first locking plate and the second locking plate abut face to face, blocking the rotation of the rotary lock seat; the rotary lock seat is provided with a lock hole, and when the rotary lock seat is in the locked position, an external lock can be inserted into the lock hole and locked. This lockable sliding switch has the characteristics of double locking to prevent misoperation, stable gear switching, and reliable contact.
