Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a single facer for manufacturing single-sided corrugated board, in which one or both of the lower roll and the upper roll can be replaced very quickly.

As previously shown in Japanese Patent Publication No. 56-20983 and Japanese Patent Application Laid-open No. 53-85687, the present inventor has provided a method for forming a large number of grooves by surrounding the roll surface with a large number of grooves at the bottom of each groove. Invented a single facer equipped with a suction type lower roll that has suction holes and suctions paper through the groove,
As a result, high-quality single-sided corrugated cardboard can now be produced at high speed and with high efficiency. In this single facer, %
In order to clean the grooves, prevent wrapping of the liner paper, and improve suction efficiency, a doctor blade is provided above the valley grooves of the lower roll that is not in contact with the liner paper. In addition, as shown in Japanese Patent Application Laid-open No. 53-119189, %
A flushing nozzle device capable of injecting steam is provided above the lower roll to prevent clogging of each of the suction holes. In addition, recently, the entire single face has been covered with sound-insulating and sound-absorbing material to prevent noise.In addition to these, an air cylinder, U lever, air piping, paper roll, moisturizer, etc. have been installed above the 7th frame. Under such circumstances, the work of lifting and replacing the upper and lower U-rolls and pressure rolls requires more than one day of work to remove and reassemble the equipment installed above each roll. The purpose of the single facer operation is to provide a single facer that saves time and allows long hours of work to be done in an extremely short time. Further objects of the invention will become apparent from the following detailed description and the accompanying drawings.
