4. ترتیب کول
Before operating the SF150W, ensure it is properly set up:
- ځای په ځای کول: ماشین په یوه مستحکم او هموار سطحه کېږدئ. د عملیاتو او ساتنې لپاره د ماشین شاوخوا کافي ځای ډاډمن کړئ.
- د بریښنا پیوستون: Connect the machine to a power supply matching the specified voltage (110V or 220-240V/50-60HZ, 1 PHASE). Ensure the power outlet is properly grounded.
- Conveyor Table Adjustment:
- Use the conveyor table adjust button (refer to Figure 3.6) to set the height and position of the conveyor table.
- Adjust it to align with the size of the product bags you will be sealing, ensuring the bags pass smoothly through the sealing area.
- Printing Wheel Installation (Optional): If date or character printing is required, install the appropriate steel pressing printing wheels. Ensure they are correctly aligned for clear impressions.
- لومړنۍ معاینه: Before powering on, visually inspect the machine for any loose parts, damaged cables, or obstructions in the sealing path.
5. عملیاتي لارښوونې
Follow these steps for safe and effective operation of the SF150W:
- پاور آن: Turn on the main power switch on the control board (refer to Figure 3.3).
- د حرارت درجه تنظیم کړئ: Adjust the temperature knob on the control board to the desired sealing temperature (0-300℃) based on the type and thickness of the film being used. Allow a few minutes for the heating blocks to reach the set temperature.
- Set Sealing Speed: Adjust the speed knob on the control board to the desired sealing speed (0-12 m/min). Start with a lower speed and gradually increase as needed.
