1.2.1Will help improve the speed

Echelon type sizing machine does not need to set gear at both ends of the roller sheet , the glue is a continuous flow from the nozzle of the glue to the roller surface, the excess glue from the ends of the inflow received in the end surface of plastic bucket after the glue into the heating tank through the return pipe , flows into the surface of the roller of such a cyclic process. Not required to maintain a certain level , it prevents scattered phenomenon . Meanwhile , the number of which is the amount of sizing through a line pressure between the rolls to be changed. Glue nozzle manifold switch to control the quantity of glue size , so that excess glue is reduced to a minimum, to ensure that the glue is not hierarchical , but also ensures the uniform sizing amount .

1.2.2 Threading easy

Echelon type sizing machine threading using ropes secured to the lower roller wheel bearing shell , prior to adjust the relative position , so that the next roll with three songs compressed air tube to a position just to make rope sheaves on by pressing area, after the paper cited , the next roll reset sheave is pushed to the rear to avoid contact with the rope and glue too close to prolong the life of the rope . To plastic bucket is also fixed on the lower roller and a lower roller rocker arm movement together , threading when shortened breaks , reduce labor intensity , making operation simple.

1.2.3 Can be single-sided or double-sided glue sizing

When the echelon leading roll size press into the pre- sizing the frame to be movable back and forth 25 °, the sizing of the leading roll can be moved, such that the web on a roll coated with 5 ° to 15 ° Single sizing , coating 30 ° and 40 ° sided sizing , while closing the nozzle or the lower -sided glue sizing roll to one side to achieve the purpose of sizing .

Vertical structure is conducive to the sheet running, but both sides of the sheet material nip pool depth Although the level of structure ranging sheet pool depth on both sides of the same material, to solve the different amount Adsorption problem, but the requirements of a vertical run sheet brought trouble operation. Therefore, Inclined size press been widely used. Traditional oblique angle out of the general structure At 15°~45.°, The two sizing rollers of the same diameter. If you press the tilt 45°Design, the Low level material pool, small volume, the impact of the sizing effect. If you press tilt 15° Design, although the level of increase in the feed tank, a relatively large volume. But unfavorable In operation and maintenance. To improve the sizing level. Increased material Cell volume, the size of the roll diameter rollers are designed to form the outer diameter of the roller 965mm,The outer diameter of the lower roll 1265min, and because of the tilt angle is conducive to the sequence set Equipment such as arc-shaped roll, steering layout, operation and maintenance more convenient.

2 main structural features

Sizing mainly by outsourcing stainless steel plate welded frame , roller , lower roller. Guide Rollers, the pressing device , the liquid supply means , the transmission means . Then plastic tray , independent Zhisheng Pei set , hair threading device . Warm water devices , thin oil lubrication devices and other components ( see Figure 2 ) . Tire air pressure , the sheet in 8 % to 12 % of water by the paper roll and the primer Connecting the centers of the two pressure rollers 90 . Into the pool with rubber sizing nip. After sizing by arc After the rolls into the oven to continue drying .
