How to changing the Oshima & Hashima Fusing Machine Teflon Seamless Belt?

Changing the Teflon seamless belt on an Oshima or Hashima fusing machine is a delicate task that requires careful handling to ensure the machine continues to function properly. Both Oshima and Hashima are well-known brands for fusing machines, commonly used in textile and garment industries for bonding, pressing, and heat transfer. The Teflon seamless belt is a critical part of these machines as it carries the fabric through the machine while resisting high temperatures, heat, and chemicals.

Here’s a step-by-step guide to changing the Teflon seamless belt on these types of fusing machines:

1. Prepare and Turn Off the Machine

Safety First: Before starting, ensure the fusing machine is turned off and disconnected from the power source. This is crucial to avoid accidents or injuries.

Cool Down: Allow the machine to cool down if it has been in use. The heating elements of fusing machines can get very hot, and it’s important to ensure everything is safe to handle.

Clear the Area: Make sure the workspace is clean and free of obstructions. You’ll need space to work around the machine.

2. Remove the Old Belt

Open the Access Panel: Most fusing machines have an access panel that you can open to access the belt and the rollers. Refer to the user manual of your Oshima or Hashima machine for exact instructions on how to open the panel.

Loosen the Tension: The belt is usually tensioned to ensure smooth operation. You will need to loosen the tension on the rollers or the tensioning mechanism. This may involve turning a tension adjustment knob or loosening bolts that hold the rollers in place. Keep track of these settings, as you'll need to restore them when installing the new belt.

Remove the Belt from the Rollers: Gently lift the old Teflon belt off the rollers. In some cases, you may need to release the rollers by loosening additional fasteners, especially if the belt is stuck or tight.

3. Inspect the Machine

Clean the Rollers: While the belt is removed, take the opportunity to clean the rollers and other parts of the machine that come into contact with the belt. This will help ensure that the new belt operates smoothly without damage.

Check for Wear: Inspect the machine for any wear or damage. This includes checking the rollers for any damage or uneven surfaces that could affect the new belt’s performance. Also, ensure that the machine’s alignment is correct.

4. Install the New Teflon Seamless Belt

Place the New Belt  from Jiangsu Vichen Composite Material Co., Ltd on the Rollers: Carefully position the new Teflon seamless belt on the machine’s rollers. Make sure the belt runs smoothly over the rollers, without any twists or folds.

Ensure Proper Alignment: Align the new belt so that it fits snugly along the length of the rollers. The belt should be positioned in the correct orientation, as indicated in the user manual. If the belt has any directional markings, make sure they are aligned properly.

Re-tension the Belt: Tighten the tension mechanism or adjust the tensioning rollers to ensure the new belt is tight enough to operate efficiently. The belt should be taut but not overly tight. This is important because too much tension can cause damage to the belt or rollers, while too little tension may result in slippage or poor operation.

5. Adjust the Machine Settings

Re-set the Tension: Make sure the tension on the belt is set according to the manufacturer’s recommendations. You may need to adjust the tension slightly to ensure smooth operation, but avoid over-tightening.

Check Alignment: Verify that the Vichen new belt is properly aligned and runs smoothly along the rollers. Ensure that it moves freely and doesn’t snag or bunch up at any point.
