Guideless single-sided machine related cardboard defects -5

Bladeless single-sided machine related to the cardboard defect in the operation of the foaming situation Two corrugated top scraping adhesive phenomenon, because the corrugated core paper before the entry into the lower corrugated roller and the rubber roller nip point has occurred relaxation phenomenon .
the reason
a. Insufficient vacuum or pressure
b. Vacuum hole plugging
c. Corrugated roller with dirt
d. Corrugated roller under pressure
e. Corrugated roller bearing wear
f. Corrugated Roller Heat Insufficiency Measures a. Increase vacuum and pressure b. Remove dirt from holes c. Remove the dirt from the corrugating roller d. Improve occlusal pressure e. Replace bearings {. Checking the siphon case The top of the three corrugated squeegee adhesive is scraped because the corrugating medium is slack before it enters the lower corrugating roll and pressure roll nip. The reasons and measures for this are given in Scenario 2, with the following additions:
The reason is that the rubber roller hits the tip of the corrugated roller and the unsealed glue on the four-sided paper. .
the reason
a. The gap between the top roller and the corrugating roller is too large
b. The gap between the top roller and the metering roller is too small
c. Condensate on the steam jet falls on the upper roller
d. The gel starch on the baffle wipes off the glue on the core paper
e. Paste level in glue pan is too low
f. Poor contact between the lower corrugating roller and the pressure roller or no contact measures to increase the gap between the rubber roller and the corrugating roller, a. Reduce the gap.
b. Increase the gap c. Repair the condensate drain on the steam ejector d. Clear the paste block on the baffle e. Increase the paste surface f. Check pressure roller pressure Check pressure roller positioning device 'Check pressure roller height
