Process introduction of the producing line
(1) The process route of bag-making
Coiling of plastic-weaved cloth (PP、PE) →coiling up in bracket ---printing in obverse and reverse side with four to six color---cutting (equipping computer to treat )—bag tube turning--- rectifying and checking--- forward position orientation---spreading glue--- stoving--- opening bottom---bag bottom adjusting--- pasting mouth of valve--- forming--- sticking attached bottom --- folding in reverse side to press--- producing bag and stacking up. The bag-making procedure is accomplished continually in one time, and the shape of the bag is valve mouth and square bottom
The whole product line assembles the control of machine, electricity and steam
(2)The adaptation scope
1. The adaptation scope for packaging: cement, grain, flour, fodder, carbon black, chemical material and other things with the form of powder, grain and tablet.
2. The adaptation scope of bag-making material: polypropylene-weaved cloth (PP), polyethylene film (PE)
3. the gram weight of adaptation materials: polypropylene-weaved cloth with film covering (PP)>=105g/㎡, polyethylene film (PE) with the thickness of 0.15-0.2mm, or other plastic bag-making materials.
4. The adaptation shape of bag: valve-mouth and mouth-opening bag
5. the adaptation specification scope of bag-making: freely adjust the length of bag from 430~960mm, freely adjust the width of bag from 380～700mm, freely adjust the width of bag from80～160mm
6. the adaptation printing requirement of bag-making: chromatography with 4～6 color, flexible resin plate, pneumatic net roller ascend and descend, printing ink circle automatically, photoelectricity rectify a deviation automatically
