Self-supporting bag so fire, its production procedures and key points of production to know

A, production procedures 1, prepare: installation of horizontal heat sealing, bottom heat sealing knife, strengthening heat sealing knife, install the punching device. 2, wear, set the EPC, bag edge alignment and pattern. 3, heat sealing at the bottom of the knife, the length of the input size, the position of the knife direction to flush, based above the knife blade adjustment, check whether the hole is circle. Set photoelectric sensors. 4, install base film, adjusted to fold in the middle. Adjustable punch bottom film. 5, the lateral heat sealing, and printing position alignment in the position of heat sealing knife. 6, strengthening heat sealing, filling pressure in the location of the junction of four layers. 7, adjust good knife, edge cutting device. 8, confirm and adjust self-reliance bag surface, bottom heat sealing position of drilling hole. Identify and adjust the lateral heat sealing knife, strengthen the position of the heat sealing piece. Confirm the heat sealing strength, heat sealing temperature adjustment. Second, the key points of production 1, basement membrane tension is too high. Tension is too high, the bottom of the round hole will be out of shape. General tension of 0. 05 ~ 0. 2MPa。 2, the first set of heat sealing knife, high pressure, low temperature, the second and third group with normal temperature and pressure. 3, strengthen heat sealing piece of spring pressure adjustment is zero, only make the weight of heat sealing device. 4, silica gel plate hardness is commonly used in 50 & deg; , hot sealing area is lesser use 70 & deg; The board. 5, heat sealing, bottom hole called oval can increase the waiting time for 100 min. 6, self-reliance bag, bag making speed is generally 50 ~ 100 / min.
