Corrugated cardboard processing line
Technical field
The utility model relates to a kind of corrugated cardboard processing line.
Background technology
As shown in Fig. 1 to Fig. 3 and Fig. 5, Fig. 7, existing corrugated cardboard processing line comprises two for making the cardboard workspace 10 of cardboard 13, described each cardboard workspace 10 has two base paper roll stands 11 respectively, two base paper roll stands 11 are equipped with facial tissue 111 and core paper 112 respectively, facial tissue 111 and core paper 112, respectively through after preheating cylinder 14, enter single Corrugating Machine 12 and carry out fitting and form cardboard 13.Two cardboards 13 out and enter Double-plate machine 40 from another base paper roll stand 20 facial tissue 21 out after triple preheating cylinder 60 and glue spreader 30 and fit from two cardboard workspaces 10, cardboard 13 after laminating after the rotary cutting on streamline gives up machine 70, slitting line pressing machine 80, transverse cutting unit 90, sheet stacker 100 and descending sheet stacker 110, has just made finished product again.Although above-mentioned corrugated cardboard processing line achieves the full-automatic generation of corrugated board, and has higher productivity ratio, its energy resource consumption is relatively serious, major defect have following some:
1. preheating cylinder 14 diameter in existing cardboard workspace 10 is 900mm-1200mm, function be guarantee paper can with paste gel must more than 60 DEG C temperature, but because preheating cylinder 14 adds warm spot to laminating points apart from long, a paper temperature is is easily scattered and disappeared, must baking temperature be strengthened, so just cause energy waste and paper physical property is destroyed.
2. existing triple preheating cylinder 60 diameter is 900mm-1200mm, function be guarantee paper can with paste gel must more than 60 DEG C temperature, but because preheating cylinder 60 adds warm spot to laminating points apart from long, a paper temperature is is easily scattered and disappeared, must baking temperature be strengthened, so just cause energy waste and paper physical property is destroyed.
3. existing Double-plate machine 40 comprises hot plate section 41 and cold drawing section 42, wherein the function of cold drawing section 42 is to draw paper for main heat radiation of holding concurrently, length more than 6 meters, canvas top board 6 pieces or pressure roller more than 20, produce real gap and produce transition pressure work in the face of cardboard, cause the withstand voltage deterioration of cardboard.
4. the boiler pressure of existing streamline is more than 10kg, temperature 165 DEG C, vapour system to pick platform with pipeline, each standalone unit body is also more than 10kg, the each cell cube in real gap production face is temperature required is different, too high temperature can make paste slaking before not permeating completely on the contrary, causes false laminating, thus forms the wasting of resources.
