Description

Pulp suction control method for paper-plastic partition

Technical Field

The invention relates to the technical field of pulp suction adjusting equipment, in particular to a pulp suction control method for paper-plastic partition.

Background

And more than two mold inserts, wherein the pulp is sucked on the side wall of the mold inserts when the pulp is sucked in the vacuum holes, so that the fiber cannot be completely attached to the side wall of the mold inserts, and the pulp fiber is arranged between the mold inserts. So that the fiber can not be absorbed by one of the side walls of the mold insert, and the fiber after pulp absorption is distributed in a crossed way. The cross-shaped fibers are extruded from the mold insert sidewalls onto the plane between the mold inserts after the mold is closed.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present invention.

Referring to fig. 1 to 2, the paper-plastic partition pulp suction adjusting mechanism of the invention comprises a die body 1 and a pulp suction adjusting mechanism 2 arranged on the die body 1, wherein the pulp suction adjusting mechanism 2 comprises an insert 21, the insert 21 is inlaid on the die body 1, an air chamber 26 is formed between the insert 21 and the die body 1, an air pipe 23 is arranged on the insert 21, and a PV valve 22, an electromagnetic valve 24 and a PLC25 are arranged on the air pipe 23. The problems of light transmission of the side walls of the product pockets and plane bulge and uplift between the product pockets are also solved.

Wherein, the pulp sucking adjusting mechanisms 2 are arranged in a plurality and are distributed at equal intervals.

And the die body 1 is fixedly connected to a workbench, and the workbench is connected with an oil hydraulic cylinder of a forming machine.

In addition, a solenoid valve 24 is provided between the PV valve 22 and the PLC 25.

For easy installation and removal, in this embodiment, the air pipe 23 is divided into a vertical pipe and a lateral pipe, and the vertical pipe and the lateral pipe are screwed together by the PV valve 22.

In order to achieve a better sealing effect, a sealing ring is fixedly sleeved on the PV valve 22.

The paper-plastic partition pulp suction control method has the following structural operation modes:

1) Insert arrangement: when the number of the mold inserts is N, arranging the inserts in sequence; the mold inserts are divided into a first insert 211 and a second insert 212, so that each mold insert is subjected to zone control in sequence.

2) The hydraulic cylinder of the forming machine pushes down the workbench to enable the die on the workbench to be immersed in the slurry tank, and the whole die insert is immersed in the slurry tank.

3) Pulp is sucked for the first time: the solenoid valve I241 of the mold insert I211 is opened, the PV valve I221 is controlled by the solenoid valve I241 to automatically open vacuum, the mold insert I211 starts to suck the slurry for about 1 to 10 seconds, and the slurry is uniformly adsorbed on the surface of the mold insert I211 after the slurry is sucked for the first time.

4) After the first suction is finished, the PV valve I221 is controlled by the electromagnetic valve I241 to automatically close the vacuum of the die insert I211.

5) And (3) pulp suction for the second time: opening the solenoid valve II 242 of the mold insert II 212 controls the PV valve II 222 to automatically open the vacuum, the mold insert II 212 starts to suck the slurry for about 1 to 10 seconds, and the slurry is uniformly adsorbed on the surface of the mold insert II 212 after the second slurry suction.
