I. Production Procedures

1. Preparation: Install the horizontal heat-sealing knife, bottom heat-sealing knife, and reinforced heat-sealing knife, and install the punching device.

2. Film threading, EPC setting, aligning the bag edge and pattern.

3. Adjust the bottom heat-sealing knife, input the length Size, the knife's position and direction must be aligned, adjust the knife using the upper knife as a reference, check if the round hole is circular. Set the photoelectric sensor.

4. Install the bottom film and adjust it to the middle fold. Adjust the bottom film punching.

5. Adjust the horizontal heat sealing to align the heat sealing knife position with the printing position.

6. Adjust the reinforced heat sealing block, supplementing pressure at the four-layer intersection.

7. Adjust the cutting knife and the edge material cutting device.

8. Confirm and adjust the bottom punching position and bottom heat sealing position. Confirm and adjust the position of the horizontal heat sealing knife and the reinforced heat sealing block. Confirm the heat sealing strength and adjust the heat sealing temperature.

II. Production Key Points

1. The bottom film tension should not be too high. If the tension is too high, the round holes on the bottom will deform. The general tension is 0.05~0.2MPa.

2. For one set of heat-sealing knives, use higher pressure and lower temperature; for the second and third sets, use normal temperature and pressure.

3. Adjust the spring pressure of the reinforced heat-sealing block to zero, allowing only the self-weight of the heat-sealing device to take effect.

4. Generally, use 50° hardness silicone rubber plates; use 70° plates when the heat-sealing area is smaller.

5. When heat sealing, if the bottom round hole becomes elliptical, increase the waiting time by 100min.

6. The bag making speed is generally 50~100 bags/minute.

Through the understanding of the above stand-up pouch editor, I hope it can help you.
