As a pioneer in band saw paper cutter design and manufacturing, YYS Machinery holds multiple patented technologies, enabling us to deliver industry-leading, unique roll-to-roll cutting solutions for global clients. Today, we introduce our patented small roll slitting machine(CN215589283U).

Technical Field

The utility model pertains to the technical field of paper cutting equipment, specifically a paper cutter designed for slitting rolls.

Background of the Small Roll Slitting Machine

Paper roll cutting machines are widely used in the printing and packaging industry. Conventional machines involve fixing the paper roll, then using a saw blade to cut the rotating roll into sections of specific lengths for packaging.

Existing paper roll cutting machines rely on manual operation for saw blade positioning and the cutting process, limiting efficiency and adaptability to different cutting requirements.

Disclosure of Invention

The utility model provides a paper cutter for slitting rolls capable of automating saw blade positioning and the paper roll cutting process.

The paper cutter comprises:

• A rack
• A rotating mechanism (two rollers driven by a first driving piece)
• A roll blocking mechanism (for lateral paper roll alignment)
• A tool rest adjusting mechanism (sliding seat and rotating frame with a first lead screw for height adjustment via a third driving piece)
• A cutting mechanism (saw blade driven by a fourth driving piece)
• A control unit (signaling all driving pieces)

Preferred Embodiments

1. The roll blocking mechanisms are divided into left and right groups, slidably connected to the rack.
2. One group connects to a screw rod bearing, rotationally matched with a second screw rod linked to a hand wheel.
3. One roller mounts on sliding blocks driven by a fifth driving piece (signal-connected to the control unit).
4. The fifth driving piece operates two second worm gear lead screw elevators to adjust third lead screws along the rack.
5. The control unit includes a touch screen and buttons for operation.
6. A speed reducer connects the first driving piece to the roller.
7. The saw blade features rotatable shields (first and second shields).
8. A cross bar links the second shield to the sliding seat.
9. An air suction cover is installed behind the saw blade on the sliding seat.

Advantageous Effects

The utility model enables automated adjustment of roller positions, roll blocking alignment, and cutting mechanism placement via the control unit, ensuring precise and efficient paper roll slitting without manual intervention.
