由给料机实期送粉料（胶体或液体）到包装机上方的料斗器内，无纺布制袋机引进速度由光电定位装置控制，成卷的封口纸（或其它包装材料）经导辊带动引进至翻领成型器，被折弯后再由纵封器搭接成为圆筒状，无纺布制袋机物料被自动计量后充填到制成的袋内，横封器在进行热封切割的同时将袋筒间歇地向下牵引，最后形成搭接纵缝三面封口扁平袋，完成一个袋的封口。
The powder (colloid or liquid) is fed into the hopper above the packaging machine by the feeder during the actual period. The introduction speed of the non-woven bag making machine is controlled by the photoelectric positioning device. The rolled sealing paper (or other packaging materials) is introduced into the lapel shaper by the guide roller. After being bent, it is lapped into a cylinder by the longitudinal sealer. The materials of the non-woven bag making machine are automatically measured and then filled into the bag At the same time of heat sealing cutting, the horizontal sealer pulls the bag barrel down intermittently, and finally forms a flat bag with three sides of overlapping longitudinal seam to seal one bag.
此封口机构能在同一台设备上、同一竖直方向上自动完成包装袋成型、计量、打印日期、充填、封口、切断、输出等工序，所用包装材料主要是具有可热封的塑料单膜的各种复合膜（如纸－塑复合，塑－塑复合，铝－塑复合等）。
The sealing mechanism can automatically complete the process of bag forming, measuring, printing date, filling, sealing, cutting, output, etc. on the same equipment and in the same vertical direction. The packaging materials used are mainly various composite films with heat sealing single plastic film (such as paper plastic composite, plastic plastic composite, aluminum plastic composite, etc.).
系统采用LEC－200BM－G05D小型光电编码器进行位移测量，采用8031单片机进行运动控制，能保证纵、横向封接可靠且顺利进行，包装纸的运动速度能有效地得到控制，尤其是能保证印有彩色图案的商标，定位切割准确无误。
The system uses lec-200bm-g05d small photoelectric encoder to measure the displacement, and uses 8031 single chip microcomputer to control the movement, which can ensure the vertical and horizontal sealing is reliable and smooth, and the movement speed of packaging paper can be effectively controlled, especially the trademark with color pattern can be guaranteed, and the positioning and cutting are accurate.
