Nut is fixedly installed on pressing plate, bolts and nuts are threadedly coupled, and the upper-end contact of bolt lower end and sliding block；The bottom surface of sliding block
Spring is vertically arranged between rack.The both ends of the upper air-breathing roll shaft are separately positioned on two regulating devices by bearing
On sliding block.Bolt is rotated, spring promotes sliding block to be moved up along slide under restitution, reversely rotates bolt, bolt pusher
Sliding block is moved down along slide, and compresses spring.The centre-to-centre spacing of upper air-breathing roll shaft and lower air-breathing roll shaft is adjusted by sliding block movement,
To meet the needs that support mouth is carried out to the paper bag of different-thickness.
Be further improved, set on the upper air-breathing roll shaft there are two upper air-breathing roller, and two upper air-breathing rollers with lower suction
Gas roller is tangent, then can simultaneously two paper bags be carried out with support mouth action, efficient.
It is further improved, " V " type compartmentation strip, " V " type compartmentation strip and lower air-breathing is provided in the cavity of the lower air-breathing roller
Roller inner wall forms section as fan-shaped passage, and lower suction hole is connected by the passage with the aperture on lower air-breathing roller end face.Pass through
" V " type compartmentation strip is set to reduce the air intake passage volume in lower air-breathing roller, ensures the vacuum effect at lower suction hole, reduces
In passage, ensure inspiratory effects.
It is further improved, the angular velocity of rotation of the upper air-breathing roller is equal with lower air-breathing roller angular velocity of rotation, i.e., upper air-breathing
Roller, lower air-breathing roller often rotate a circle, and upper suction hole is with lower suction hole in upper air-breathing roller, lower air-breathing roller the tangent corresponding matching one
It is secondary, it completes once to support mouth action.
It is further improved, there are three upper suction hole, lower air-breathing roller rollers for setting in the axial direction on the upper air-breathing roller roll surface
Suction hole under two rows is staggeredly equipped on face, by increasing air-breathing hole number on upper air-breathing roller roll surface, ensures the paper of paper bag
By firm absorption, prevent paper departs from suction hole from causing to support mouth failure；It is staggeredly equipped under two rows and inhales on lower air-breathing roller roll surface
Stomata, according to the quantity of the corresponding lower suction hole of paper bag specification selection, remaining no lower suction hole is sealed using screw.
The present invention has the advantages that：
1st, after paper bag enters between upper air-breathing roller, lower air-breathing roller roll surface, due to being negative pressure at upper suction hole, lower suction hole, then
Paper bag above and below is attracted on air-breathing roller, on lower air-breathing roller roll surface respectively, and with rotation, paper bag above and below is softened mouth, from
Dynamicization degree is high, and continuous work, stable and reliable operation improves production efficiency.
The 2nd, regulating device, by moving up and down for sliding block, the center of air-breathing roll shaft and lower air-breathing roll shaft in adjustment are set
Away to meet the needs that support mouth is carried out to the paper bag of different-thickness.
