The automatic woven bag bagging machine is suitable for the production of large-scale national chemical, fertilizer, building materials, and cement plastic woven bags. The machine has the function of streamlining operation, and has the advantages of low labor intensity and high work efficiency. It is a special equipment for automatic bagging of inner film and outer bag. It integrates outer bag unwinding, automatic correction, outer bag cutting, inner film unwinding, inner film bag heat sealing, inner film bag cutting, inner and outer bag collection, and after bagging The back cover, counting and palletizing functions are integrated, with simple operation and high degree of automation.
At present, the domestically produced fully automatic woven bag bagging, cutting and sewing machine has the following characteristics and performances: one is pneumatic winding, which is convenient and labor-saving; the other is the automatic completion of the fixed-length thermal cutting, bottom sewing and thread trimming of the woven fabric. Save labor; the third is to use a servo motor to drive the optical encoder to measure the length, and the bag length can be precisely controlled; the fourth is the color code tracking photoelectric; the fifth is to use a hot knife cutter and a copper plate or a combination of hot knife cutter and silicone to cut the woven bag; After thermal cutting, the bag is automatically peeled off, and the bag is not sticky and easy to open; seventh, the inner film is automatically heat-sealed, cut and bagged; eight is automatic counting, the bag can be stacked and fed; nine is the automatic device PLC control, touch screen operation.
However, the outer bag cutting generally uses a combination of hot cutter and copper plate or hot cutter and silica gel to cut the woven bag. This kind of cutting device requires a high temperature of the cutter heating (above 280°C).
Since the cutting knife often collides and squeezes with the copper plate or silica gel during the bag cutting process, it is easy to cause the cutting knife edge to become dull and defective, which affects the cutting of the woven bag. It is necessary to frequently sharpen the cutting knife edge or directly replace the cutting knife. ; At the same time, the heating temperature of the cutting knife is high, the cutting knife is easy to deform, and an uneven gap is formed between the copper plate, which not only affects the cutting of the woven bag, but also the high temperature of the cutting knife can easily melt the material of the woven bag and cause the bag mouth to stick, affecting the inner Film bagging is not conducive to the subsequent process.
