(Summary description)1. Production schedule 1. Preparation: Install the transverse heat sealing knife, the bottom heat sealing knife, the reinforced heat sealing knife, and the punching device. 2. Thread the film, set the EPC, and align the bag edge and pattern. 3. Adjust the bottom heat sealing knife, input the length and dimension, the position and direction of the knife should be aligned, and adjust the knife based on the above knife, and check whether the round hole is round. Set the photoelectric sensor. 4. Install the bottom film and adjust it to the middle fold. Adjust the bottom film and punch holes. 5. Adjust the horizontal heat sealing to align the position of the heat sealing knife with the printing position. 6. Adjust the heat sealing block and make up the pressure at the intersection of the four layers. 7. Adjust the cutter and edge cutting device. 8. Confirm and adjust the bottom surface punching position and the bottom surface heat sealing position. Confirm and adjust the position of the transverse heat sealing knife and strengthening heat sealing block. Check the heat seal strength and adjust the heat seal temperature. 2. Production points 1. The tension of the bottom film should not be too high. If the tension is too high, the circular hole on the bottom will be deformed. The general tension is 0.05~0.2MPa. 2. One set of heat sealing knives, the pressure is higher, the temperature is lower, the second and third sets use normal temperature and pressure. 3. The spring pressure of the strengthening heat sealing block is adjusted to zero, so that only the weight of the heat sealing device works. 4. The silica gel plate is generally used with a hardness of 50°, and a plate with a hardness of 70° is used when the hot sealing area is small. 5. When heat sealing, the round hole on the bottom is called oval, which can increase the waiting time by 100min. 6. The bag making speed is generally 50~100 pieces/min. Through the understanding of the above self-supporting bag editor, I hope it can help you.
