Corrugated?? Corrugated Board Production Line In The Heart Of The Nine (photos)
V. Maintenance of Corrugated In addition to high precision and high quality selection
good wear resistance than corrugated roll, corrugated roll used to improve environmental conditions and daily for proper and timely maintenance is to improve the corrugating roll life and economic performance of the two important factors, which can reduce the maximum wear Corrugated. The following describes the use of Corrugated
during the main inspection and maintenance program.
(1) Corrugated installation and maintenance projects during the inspection:
1. Pre-installation inspection and maintenance items:
(1) cleaning the flute Corrugated surface appearance inspection (including surface plating quality).
(2) Check the connection fastening parts cleaning (including internal and external thread).
(3) Check the outer diameter corrugating roll and the high (the roll surface to the middle from both ends were divided into five or more measurement points. In the high-roller testing points must be odd, high data should be balanced on both sides). Specifications with the corresponding micrometer diameter measurement (outside micrometer General Electric Co., Ltd. can buy).
(4) Check the flute Corrugated high. Dial indicator with a needle depth of measurement (the depth of needle-type indicator in China for the time being not buy, to be imported. Or can an ordinary dial indicator depth conversion).
(5) cleaning inspection file of each axis diameter corrugating roll size and appearance, diameter size with corresponding specifications of the outside diameter micrometer.
2. When installation inspection and maintenance items:
(1) the parallelism of the upper and lower corrugated roller inspection (generally in contact with the pressure roll no Corrugated high, is to install the base roll. With high eccentricity of that support Corrugated regulatory agencies have the two rollers can be adjusted to parallel) . Can be pressure-sensitive paper, carbon paper or fuse running to the second floor and the production of corrugation cardboard and corrugation on the side to determine and adjust the indentation.
(2) upper and lower corrugating roll and pressure roll parallelism inspection, the upper and lower corrugating roll and pressure roll in running the process, required to achieve three-roll axis parallel to the line pressure uniform. According to the composite of the two-story corrugated paper board to determine the indentation, respectively, the pressure to adjust both ends of the pressurized system.
(3) Corrugated and Tu Cots The parallel examination of corrugation on the coating by different amount of space requirements of the feeler or corrugated paper to detect and adjust to the both ends of the corrugating roll with the same clearance between the coating roller.
(4) examine and adjust the corrugating roll and wrap copper device, device or negative pressure wrap pressure wrap device relative position, vacuum devices or pressure chamber with corrugated roll and pressure roll seal gap structure according to different types of production line of adjustments required to control pressure and leakage, to ensure that after ironing forming close in the Corrugated cardboard can be completed such as glue and composite drying process.
(5) completion of the above items must be fixed to debug their stopper.
(6) Corrugated and pressure rollers and other roller bearings must meet the accuracy requirements, high temperature grease to use high-quality, oil seals should be sealed well. Recommend the use of DuPont (DUPONT) Krytox grease high fluoride, especially in high-speed line.
