Description
Technical field
The utility model relates to paper conversion machinery field, espespecially a kind of compression ring air-valve device for controlling negative pressure.
Background technique
Traditional V-arrangement box drawing type facial folding machine it is main it include upper left cutter shaft, upper right cutter shaft and the left side being distributed in # font
Paper folding roller, right folding paper bowl, the interior air intake passage for being equipped with six blind hole shapes of every paper folding roller are equipped with gas chamber at paper folding roller both ends, have
Three alternate air intake passages and the gas chamber of one end communicate, and the gas chamber of another three air intake passages and the other end communicates, in paper folding roller
Roll surface be equipped with and the suction hole that communicates of air intake passage, when work, paper handkerchief can be adsorbed on paper folding roller by suction hole,
In this way, the gas chamber alternating inspiratory at paper folding roller both ends, closing, the two groups of paper folding rollers in left and right is made to be respectively completed crosscutting, paper feeding, paper folding
Paper handkerchief is alternately converted into V-arrangement and stacked by movement.
The above existing V-arrangement box drawing type facial fold mechanism there are many deficiencies place, such as:
