Step 1: Preparation before startup (1 minute)
Safety inspection
• Confirm that there is no debris around the equipment and that the emergency stop button is in the reset position
• Check whether all protective covers are properly installed
• Make sure the power and air supply connections are normal
Prepare the ingredients
• Verify the specifications (width, thickness, material) of the film to be slit.
• Prepare paper tubes or plastic tubes of the required specifications
• Check that the blade is sharp and free of notches
Step 2: Tool Loading and Parameter Setting (1.5 minutes)
Knife loading operation
• Install a circular blade on the cutter shaft according to the slitting width requirements
• Blade spacing must be measured precisely and can be calibrated using calipers
• Tighten the blade fixing screw to ensure it does not shift during operation
Parameter settings
• Set the slitting speed on the control panel (beginners are recommended to start at low speed)
• Set the winding tension value (adjusted according to different film materials)
• Set meter counting length (automatically stops upon arrival)
Step 3: Film Penetration and Cutting (1 minute)
Membrane penetration path
• According to the equipment diagram or marked directions, sequentially pass the film through guide rollers, tension rollers, blade shafts, and winding scrolls
• Ensure the film is smooth and wrinkle-free
Knife adjustment
• Low-speed jog operation to observe the contact between the blade and the base blade or anvil roller
• Adjust the knife pressure to the right level (cutting too shallowly and not cutting properly, too deep causing injury)
• Adjust roller pressure to prevent film deviation
Step 4: Trial cutting and fine-tuning (1 minute)
Trial cutting
• Start the equipment at low speed and run 1-2 meters of finished products
• Stop the machine to check whether the slitting end faces are neat and whether the width meets standards
Fine-tuning
• If burrs appear: appropriately increase the tool pressure or replace the blade
• If deviation occurs: adjust the correction device or guide roller angle
• If the coil diameter is uneven: adjust the winding tension or roller pressure
Step 5: Formal Production and Finishing (0.5 minutes)
Officially operational
• After confirming the trial cut passed, set the metering length and start continuous operation
• Regularly monitor operating status during operation to prevent blade deviation and film breakage
Finishing touch
• The device automatically shuts down once the set length is reached
• Remove the finished roll and secure the film tail with tape
• Clean waste edge material and record production data
Beginner FAQ reminder
| Problem | Possible reasons | Solution |
| Cutting it cannot be cut | Blunt blades and insufficient knife pressure | Change the blade or increase the blade pressure |
| The face is not even at its proper posture | Inaccurate blade spacing and film misalignment | Re-adjust the tool and correct the deviation |
| Curl and wrinkle | Tension is too high or too little | Adjust tension control |
| The membrane edges are curled | The blade overheats or the film heats up | Reduce speed and check cooling |
Safety precautions
1. Sharp blades: Always wear anti-cut gloves when loading or changing blades
2. Do not reach out during operation: Do not touch the cutting area while the equipment is running
3. Emergency Stop: If any abnormality occurs, immediately press the emergency stop button
4. Power-off maintenance: The power must be cut off before cleaning or tool replacement
Summary
Mastering the operation of the film slitting machine is not complicated; the core consists of four steps: "tool assembly, film insertion, tension adjustment, and trial cutting verification." It is recommended that beginners complete the first three operations under the guidance of a master, gradually gain experience, and then start working independently. By memorizing these five steps, you can establish a clear operating framework in just 5 minutes, and you'll naturally feel confident when you get started.
