The band saw paper roll cutter is YYS’s flagship product, delivering high-precision, fully automated paper cutting processes—perfect for customers handling high-value paper rolls. We’ve invested extensive design expertise into this machine, and here’s a brief overview of its patented details.
Band Saw Paper Roll Cutter
Technical Field
The utility model relates to the field of paper cutting apparatuses, specifically a band saw paper cutter.
Background Technology
Currently, roll paper is processed through feeding, clamping, cutting, and discharging to obtain rolls of specific dimensions.
Existing band saw paper cutters generally consist of a sawing platform and a cutting device. The sawing platform uses rollers, while the cutting device employs a four-band-saw-wheel structure (four band saw wheels, a band saw blade sleeved on them, and two lead screws driving the wheels up and down). During operation, the roll paper is clamped and moved by the rollers, while the band saw blade rotates to perform the cutting.
However, these cutters have the following issues:
- Paper damage – Friction between the rollers and paper can damage the material.
- Unstable cutting – Irregularly shaped rolls are prone to slippage, making precise cutting difficult.
- Low efficiency & precision – Manual clamping reduces productivity and accuracy.
- Poor sawing performance –
- Small contact area between the band saw blade and wheels leads to insufficient cutting force.
- Blade instability on the wheels causes vibration due to imbalanced force distribution.
- Dual lead screw drives result in jitter, affecting cut quality.
Utility Model Content of the Band Saw Paper Roll Cutter
The purpose of this utility model is to provide a high-efficiency, high-precision band saw paper cutter with superior performance.
Technical Solution
The cutter includes:
- Feeding device – Comprising:
- A base with a groove extending into the sawing frame.
- Two clamping assemblies that work together to lift and move the roll paper toward the cutting mechanism.
- Clamping assembly details – Each includes:
- A sliding paper-holding frame.
- A rotatable collet (positioned opposite the other collet).
- A height adjustment device for vertical movement.
- First driving device – Drives one collet’s rotation.
- Two translation cylinders – Movable ends connected to the paper-holding frames for precise positioning.
- Saw cutting mechanism – Comprising:
- A sliding crane connected to the sawing frame.
- Two primary band saw wheels (vertically aligned with the paper feed direction).
- A secondary band saw wheel forming a triangular structure with the primary wheels.
- A band saw blade mounted on all three wheels.
- Steady saw device – Stabilizes the blade between the primary wheels.
- Includes two guide rollers with a perforated guide groove for smooth blade movement.
- Second driving device – Powers either the primary or secondary band saw wheel.
- Driving mechanism – Features:
- Four ball screws (at the crane’s corners) for synchronized vertical motion.
- A drive assembly (lift motor + gear reducers) ensuring precise blade control.
- Top paper lifter – For additional support:
- Two parallel rollers aligned with the base groove.
- A lifting cylinder adjusting height as needed.
Advantages
- Fully automated feeding, improving efficiency.
- High-precision sawing with minimal vibration.
- Superior cutting quality, even for irregular rolls.
