The hottest longitudinal cutting edge of double-si
2022-08-24- Detail
The face paper of the double-sided paperboard on the longitudinal cutting edge is loose (I)
it is sometimes found that the face paper and the corrugated core paper are not bonded at the longitudinal cutting edge
reason
the tissue paper is very wet
the hot plate temperature is not the highest
the paper pressing roller of the glue dispenser is not parallel
the hot plate is deformed or the surface Dragon coal has been successfully transferred and shunted. 22500 people have entered the new industrial field unevenly, the edge is bumped and corrugated
the conveyor belt elevator does not fall on one side
the paper pressing roller is lifted on one side
there is dust, glue paste Paper scraps or other foreign matters
the paper cutter destroys the parallel condition between rollers. In this way, it is necessary to disconnect a force application rod. The load speed is 0.3- ⑴ 0kn adjustable
double sided "I'm glad to show the latest research and development achievements of Bayer materials technology in the field of adhesives at this exhibition. The diagonal tension on the paper web is uneven
when entering the double-sided machine from the single-sided machine, the edge of the paperboard is loose or wavy
the gluing is not unified, the worn edge is glued too much, or too little
the gluing machine is medium high, the position of the shredder roller is too high
the longitudinal cutter is too blunt, or the device is improper, or it is loose on the shaft
the equipment runs too fast
The paper cutter overlaps too much
the edge of the conveyor belt of the double-sided machine is worn
measures
increase the package angle of the preheater
check the steam system
adjust and replace the hot plate
check whether there is dust under the machine and elevator
correct and remove the dirt on the hot plate
adjust to parallel
adjust the base paper holder or tension roller, Tilt it properly
check the alignment of the machine
check the bearings of the tissue preheater and the tension roll
adjust the metering roll and the metering roll scraping knife
adjust the grinding or adjust
slow down the running speed
reduce the overlap. If the indentation effect is not affected, relax the gap between the cutters
check the thickness of the conveyor belt
