纸塑包装制品生产工艺操作指导

纸塑包装制品生产工艺指导

Production process guidance of paper pulp packing products 一、制浆、供浆系统：Pulping and pulp supply system

1．原浆板或废回收纸：在制浆车间规划出专用的区域分类摆放好原浆板或废回收纸，在进入摆放区的原料应先做好杂质、

粘胶纸、装订针、包装带的分拣工作，以防杂质混入纸浆后影

响成品的外观和结构力。

Virgin pulp board or recycled waste paper: You need to prepare a

special place to put the virgin pulp board or recycle waste paper.

Before you put the raw material in the area, please sort out

impurities, adhesive paper, binding needing and packing belt from

raw material to prevent impurities mixed with paper pulp

effecting the appearance and structure.

2．碎浆:原料在进行破碎分解之前，先在磅秤上称好重量，然后再通过人工投料或原料输送带进给的方式逐一将原料投到

水力碎浆机的工作桶里，加入适量的水混合，然后起动碎浆机；

碎浆时间一般情况下为20～30分钟，和原料的含水率、成份

以及水温有关。

Pulping: Before pulping, you should weight, then put the raw

material to barrel of hydrapulper by manual or conveyor, add

some water, then start the machine. Generally, the pulping time is

20-30min according to the moisture content of raw material and water temperature.

3．放浆:水力碎浆机制好的浆通过机器底部的放浆阀直接排放到浓/配浆池或由连接在放浆管上的浆料输送泵到浓浆池，放浆过程中碎浆机一边运转一边打开进水阀适量的冲水；对纸浆分解度要求较高的场合，还要在浆料输送泵的后一级增加纸纤维疏解除砂磨浆机。

Draw off paper pulp: After pulping, the paper pulp will flow to pool through the release valve in the bottom of the machine, or flow to the pipe which connect to the pool. And during this process, should turn on the hydrapulper and open inlet valve to pour into some water. If you have a requirement about pulp decomposition degree, you can add one process of pulp fiber revocable sand pulping machine.

4．浓/配浆:从水力碎浆机或前一级浆泵（包括磨浆）输送到浓浆池中的浆料由安装在浓/配浆池上的浆料搅拌器充分搅拌、加水混合均匀,这时浓/配浆池中的浆料浓度应调为符合生产要求的供浆浓度约为0.8～1.5%。

这时可根据纸浆产品对防水防油防潮的要求加入适量的添加剂，对有些添加剂有特殊工艺要求的可放入碎浆机中充分搅拌混合。

Thick/mixing pulp: After the pulp flows to the pool, add some

water, there is pulp pond beater which installed on the pool to stir

the paper pulp, adjust the paper pulp to the required concentration of 0.3-0.35%.

You can add some additives in the pool according to the

requirement of water proof, oil proof and damp proof, and stir the

paper pulp to mix it.

5．供浆:前一级配浆泵将配浆池中调好浓度、搅拌均匀、符合生产工艺要求的浆通过配浆泵泵到供浆池中，再由供浆泵输送

给生产线上的各成型设备，成型设备的溢流浆通过溢流回浆管

路再回到供浆池。

Paper pulp supply: After the pulp adjusted, the paper pulp will

pumped to the pulp supply pool by pulp pump. Then pulp pump

will supply the pulp to the forming machine. The overflow pulp of

forming machine will return to the pulp supply pool through pipe.

二、产品成型系统: Forming system

1.半自动餐盒成型机开机前应检查各运动部件的润滑油情况,机

器内储气罐的排水阀、气源三联体中油杯的油量.

Please check the lubricating situation of forming machine, check

the oil mass of drain valve, gas triplets in compressed air pot

before start the machine.

2.开机前检查模具的紧固情况,模具表面网面有没有纸浆或损坏

的情况,洗模和洗毛边的供水状况以及喷嘴有没有堵塞.
