Description

湿坯翻转式纸浆模塑制品制造方法及纸浆模塑成型机 技术领域
本发明涉及一种采用模塑成型方式制作包括纸浆的植物纤维(简称纸浆；以下同)制品的方法和装置；适用于制造一次性植物纤维模塑制品，尤其适用于制造一次性非平面的纸质制品；如纸浆模塑精致包装制品、植物纤维(纸浆)模塑餐具、植物纤维(纸浆)模塑托盘、植物纤维(纸浆)模塑工业品防震垫、包装盒及包装托、一次性非平面的植物纤维(纸浆)模塑装璜装饰立体墙板(或称植物纤维立体壁纸或纸浆模塑立体壁纸)以及一切一次性植物纤维(纸浆)模塑制品，全自动植物纤维模塑成型机包含全自动纸浆模塑成型机。
背景技术
植物纤维模塑制品的制作过程是：植物纤维在吸滤成型装置中先经过吸滤成型，制成制品的湿坯，把湿坯送入到热压定型装置的热压模具内，热压模具合模并对湿坯进行热压干燥定型，制成各种形状的植物纤维模塑制品。把湿坯从吸滤模具送到热压模具，湿坯的移动都是平移，即湿坯在吸滤模具中形成，到送入到热压定型装置热压模具内，湿坯的朝向不会变化。
热压模具分热压上模、热压下模。为排气需要，热压上模或热压下模的模具表面覆有金属丝网(一般采用不锈钢丝网)。所以，热压模具上下合模时，热压上模这一面或热压下模这一面，总有一面是覆有金属丝网的，称作“热压模具的网面”，另一面没有金属丝网，称作“热压模具的光面”。由于热压下模金属丝网安装方便和热压下模真空抽吸蒸汽方便，所以热压模具的金属丝网也一般放在热压下模。“热压模具的网面”多在热压模具的下模。
植物纤维模塑制品的表面就是这样由“热压模具的网面”和“热压模具的光面”压制而成。所以，生产出来的植物纤维模塑制品与“热压模具的网面”接触的一面是带有网纹的，而另一面是无网纹的。分别称之为“制品的网面”和“制品的光面。如果“热压模具的网面”在热压模具的下模，则所以生产出来的制品也是“制品的网面”朝下，“制品的光面”朝上。
湿坯都是在表面覆有一层或几层丝网(一般采用不锈钢丝网)的吸滤成型模具上经真空抽吸形成的。吸滤成型时，接触吸滤网的一面称作“湿坯的网面”。吸滤成型过程中，随着湿坯厚度增加，对浆液的抽吸力渐渐减小，湿坯的材质越来越松而且还出现不规则的高低峰谷面，所以离吸滤网远的一面(“湿坯的网面”的背面)称作“湿坯的毛面”。
通常，带有不锈钢丝网作为吸滤网的吸滤成型模具的工作面在浆槽里是朝上进行吸浆。所以“湿坯的网面”在湿坯的下面(湿坯的网面朝下)，“湿坯的毛面”朝上；即使是翻转式吸滤模具，模具面朝下在浆槽里进行吸浆，完成吸浆后也是模具面被翻转朝上，再进行湿坯转移。所以生产形成的湿坯也是“湿坯的网面”朝下，“湿坯的毛面”朝上。
因为，湿坯的移动都是平移，把湿坯从吸滤成型模具上吸起移送到热压模具进行热压定型，结果是“湿坯的毛面”对应“制品的光面”，“湿坯的网面”对应“制品的网面”。
到目前为止，植物纤维模塑制品的“制品的光面”不光洁，“制品的光面不光”成了植物纤维模塑制品生产中的世界性难题。“制品的光面“不“光”主要是因为“湿坯的毛面”有皱纹和酥松。“热压模具的光面”很难把“湿坯的毛面”压光。
为了克服这个问题，现有的常用方法是，增大热压模具合模力和根据制品的表面效果反过来调整模具的间隙，哪里压不光就把那儿的模具间隙调小。其结果是，即便把热压模具合模力增加到很大，使制品的有些地方已经被压得发黑了而有些地方还是压不“光”，制品表面质量无明显改变；而且更令人感到棘手的是：(1)根据制品的表面效果反过来调整模具的间隙，有很大的盲目性，往往是顾此失彼，难达目的；(2)调整模具间隙的成本非常高，调整模具间隙要停机拆下模具对模具重新进行加工，须把200℃左右的模具降温到常温，需要很长时间，热能损失很大、花费时间太长，效率低下。
因此要发明一种方法来解决热压干燥定型时，热压模具难把制品表面压光的难题。
另外，植物纤维模塑制品的制作过程中，如果采用凹模吸浆，则形成的湿坯底部壁厚比上部厚，制品越深，湿坯壁厚越不均匀，湿坯容易被压裂，最后生产出来的制品壁厚很不均匀且容易形成有裂纹的废品；如果采用凸模吸浆可以让深制品的湿坯壁厚均匀，但湿坯移动到热压定型装置中时，热压下模也要对应凸模，生产较深制品时，如果热压下模是凸模，则制品不容易脱模。
在本行业中，既要制品的壁厚均匀又要容易脱模，是两难的选择。因此也要发明一种方法来解决这一难题。
发明内容
本发明的目的是要克服上述背景技术的不足，提供一种湿坯翻转式纸浆模塑制品制造方法及湿坯翻转式纸浆模塑成型机，以实现制品壁厚均匀、容易脱模以及制品不容易出现裂纹的理想效果，提高制品的质量和机器运行的稳定性。
发明人经过多年研究和实践发现，在热压定型时，“湿坯的网面”很容易被“热压模具的光面”压光，那么生产出来的制品，它的“制品的光面”很光洁；而“湿坯的毛面”也很容易被“热压模具的网面”压出网纹，“制品的网面”也很漂亮。
因为，吸滤成型模过程中，“湿坯的网面”先开始最早形成，最先形成的“湿坯的网面”由于直接触吸滤网，没有纤维阻力，对浆液及浆液中的纤维的真空抽吸力较大，所以“湿坯的网面”材质致密而且平整；而吸滤成型时随着湿坯变厚，吸滤模具对浆液及浆液中的纤维的抽吸力变小，湿坯的材质越来越松而且还出现不规则的有高低的峰谷面，所以“湿坯的毛面”材质酥松、表面有皱纹。

这种方法的实施，只有在湿坯离开吸滤成型模具后对湿坯进行翻转才有效。
本发明的有益效果是：把离开吸滤成型模具后的湿坯经过上下180度翻转后送入热压定型装置进行热压干燥定型。“热压模具的光面”压材质致密平整优质的“湿坯的网面”，而让有一点柔性且容易压到湿坯整体面的“热压模具的网面”去压“湿坯的毛面”。热压模具的光面可以把制品压得非常光滑，而湿坯的毛面又容易被热压模具的网面压出致密的网纹。所以制品的两面都到获得很好的加工效果，纸浆模塑制品特别是高质量的精致工业包装制品的生产难度降低了。制品的质量大大提高，合格率也大大提高，生产成本可大幅度降低。
把湿坯从吸滤成型模具中移出，再上下翻转180度，把翻转180度后的湿坯送到热压定型装置进行热压干燥定型。也实现了吸滤成型模具可以采用凸模吸浆，而热压定型装置的凹模在热压下模这一有益效果。捞浆式吸滤成型机中，采用凸模吸浆可以让深制品的湿坯壁厚均匀，而热压定型装置的凹模在热压下模，深制品又容易脱模。实现了制品壁厚均匀又容易脱模以及制品不容易出现裂纹这一理想工艺效果；大大提高制品的质量和机器运行的稳定性。

具体实施方式
本发明首先提供一种全新的纸浆模塑成型工艺，让“热压模具的光面”压“湿坯的网面”，而让有一点柔性且容易压到湿坯整体面的“热压模具的网面”去压“湿坯的毛面”，可以容易实现制品表面的光洁。先把湿坯移出吸滤成型模具，在湿坯离开吸滤成型模具后且送入到热压定型模具之前，先采用一个第二湿坯转移装置把湿坯翻转180度，再送入热压模具进行热压干燥定型；
第二，由于全自动纸浆模塑成型机结构非常紧凑，要实现这样的180度翻转，非常困难。经过发明人的多年研究和努力，一种湿坯翻转式纸浆模塑制品制造方法及湿坯翻转式纸浆模塑成型机得以成功实现。
湿坯翻转式纸浆模塑成型机含有机架1、吸滤成型装置2、热压定型装置3、第一湿坯转移装置7、第二湿坯转移装置5、控制系统(可沿用现有技术)等。在吸滤成型装置中湿坯被制作完成，第一湿坯转移装置7把湿坯从吸滤成型装置2中提取出来，再转移到第二湿坯转移装置5中的第二湿坯转移模，第二湿 坯转移模可以吸附湿坯并进行上下180度翻转，第二湿坯转移模带着湿坯上下翻转180度后，把湿坯倒置，使湿坯的网面朝上，网面朝上的湿坯被移送到热压定型装置进行热压干燥定型，作为光面的热压上模(“热压模具的光面”)压网面朝上的湿坯(湿坯的网面”)，制成干燥定型后的纸浆模塑制品，制品的两面都到获得很好的加工效果。
所述热压定型装置3可以是一个或多个(包含左热压定型装置3L和右热压定型装置3R)；所述热压下模3c可以是一个或多个(包含左热压下模3Lc和右热压下模3Rc),所述热压上模3a可以是一个或多个(包含左热压上模3La和右热压上模3Ra)；
本发明所述上下翻转180度，是指第二湿坯转移模工作面5M由朝上转换为朝下，或者由朝下转换为朝上。
所述的“提取”，均是采用负压吸附的方式，由某一组件将湿坯或半成品转移到另一组件中；为现有技术。
根据热压定型装置数量不同和翻转后湿坯移送到热压定型装置的移送方式不同，湿坯翻转式纸浆模塑制品制造方法和湿坯翻转式纸浆模塑成型机可以有多种实施方式，具体描述如下：
实施例1

在下机架1a的中间设置有吸滤成型装置2，在上机架的中间、吸滤成型装置2的上方设置有第一湿坯转移装置7，在机架的左右两侧各设置有一个热压定型装置3，分别是左热压定型装置3L和右热压定型装置3R，左热压定型装置3L和右热压定型装置3R也位于吸滤成型装置2和第一湿坯转移装置7的左右两侧。
吸滤成型装置2含有吸滤成型模具2a、吸滤成型浆槽2b；
第一湿坯转移装置7含有第一湿坯转移模7a、第一湿坯转移模动力传送机构7b。
吸滤成型装置2中的吸滤成型模具2a把浆液中的纤维制成湿坯，第一湿坯转移模7a把所述湿坯从吸滤成型模具2a中吸起并上升到位。
适当浓度的植物纤维与水的混合物(简称为浆液)被间歇或连续注入到吸滤成型浆槽2b中，吸滤成型模2a把浆液制成湿坯，可采用多种方式实现湿坯的制作。
如图1.1、图1所示,左热压定型装置3L含有可上下移动的左热压下模3Lc、左热压下模驱动装置3Lf、固定在上机架的左热压上模3La。左热压上模3La和左热压下模3Lc是一对相匹配的热压模具，称为左热压定型模具(左热压模具)。左热压下模3Lc在左热压下模驱动装置3Lf的驱动下，可进行上下移动。
右热压定型装置3R含有可上下移动的右热压下模3Rc、右热压下模驱动装置3Rf、固定在上机架的右热压上模3Ra。右热压上模3Ra和右热压下模3Rc是一对相匹配的热压模具，称为右热压定型模具(右热压模具)。右热压下模3Rc在右热压下模驱动装置3Rf的驱动下，可进行上下移动。
左热压下模3Lc和右热压下模3Rc统称为热压下模3c，左热压上模3La和右热压上模3Ra统称为热压上模3a。
如图1.1、图1.1a、图1.1b、所示,在上机架的下侧固定着2根(或2组)从左端到右端的左右平移轨道8，左右平移轨道8上设有可沿导轨水平滑动的左右平移轨道滑块9，在左右平移轨道滑块9上固定着第二湿坯转移装置5，第二湿坯转移装置5通过左右平移轨道滑块9倒挂在上机架的下侧，可沿左右平移轨道8水平左右移动。
如图1、图1a所示,也可以把左右平移轨道8固定在下机架，在下机架上固定2根(或2组)从左端到右端的左右平移轨道8，左右平移轨道8上设有可沿导轨水平滑动的左右平移轨道滑块9，在左右平移轨道滑块9上固定有第二湿坯转移装置5，第二湿坯转移装置5通过左右平移轨道滑块9可沿左右平移轨道8左右移动。
如图1、图1a、图1.1、图1.1a、图1.1b所示,第二湿坯转移装置5含有第二湿坯转移模5a、湿坯翻转驱动器5b、第二湿坯转移装置移动架5c、第二湿坯转移装置水平驱动器6；第二湿坯转移模5a用来吸附湿坯的模具面是“第二湿坯转移模工作面”5M；第二湿坯转移模5a在湿坯翻转驱动器5b的驱动下可以进行上下180度翻转。由图可知：第二湿坯翻转轴5.1，通过轴承可转动地定位在第二湿坯转移装置移动架5c上，湿坯翻转驱动器5b(如带减速机的电机)的座体固定在第二湿坯转移装置移动架5c的一侧，湿坯翻转驱动器5b的驱动轴(如电机输出轴或减速机输出轴)与第二湿坯翻转轴5.1同轴连接；显然，湿坯翻转驱动器启动，即可驱动第二湿坯转移模绕第二湿坯翻转轴5.1进行180翻转。
如图1.1、图2.1、图3.1、图1、图2、图3所示,第二湿坯转移模5a可以带着由第一湿坯转移模7a转移过来的湿坯进行上下180度翻转，翻转后，第二湿坯转移模工作面5M及所吸附的湿坯朝下(湿坯的网面朝上)，上下翻转180度后的湿坯被交替送到左热压定型装置3L和右热压定型装置3R进行热压干燥定型。第二湿坯转移模5a进行上下180度翻转的方式有多种，作为优选方案，第二湿坯转移模5a进行的上下180度翻转，可以绕着一平行于水平面的轴线进行，即可以绕轴线上下180度翻转，达到把第二湿坯 转移模工作面5M从朝上翻转到朝下的目的。
驱动第二湿坯转移装置5进行水平移动的是第二湿坯转移装置水平驱动器6。如图1.1a、图1.1b、图4.1、图1a、图5所示,第二湿坯转移装置水平驱动器6采用齿轮齿条驱动方式，所述第二湿坯转移装置水平驱动器6含有固定在第二湿坯转移装置5上的齿轮动力头6a、固定在下机架上或上机架的齿条6b，齿轮动力头6a含有齿轮和驱动齿轮转动的伺服电机，齿轮与齿条6b相啮合，伺服电机驱动齿轮转动从而带动第二湿坯转移装置5左右水平移动。或者，驱动第二湿坯转移装置5进行水平移动的是直线电机，直线电机的动子固定在第二湿坯转移装置5上，直线电机的定子固定在上机架或下机架上；或者，驱动第二湿坯转移装置5进行水平移动的是丝杠螺母副机构；

第一湿坯转移模7a把湿坯从吸滤成型模具2a上吸起并上升到位，在第二湿坯转移装置水平驱动器6的驱动下，第二湿坯转移装置5带着第二湿坯转移模5a沿左右平移轨道8进入到第一湿坯转移模7a的下方，在上一生产周期中湿坯被转移走后的第二湿坯转移模5a，这时的第二湿坯转移模5a的“第二湿坯转移模工作面”5M是朝下的，所以第二湿坯转移模5a需要进行上下翻转180度，让第二湿坯转移模工作面5M朝上，即第二湿坯转移模工作面5M朝向第一湿坯转移模7a，以便接纳从第一湿坯转移模7a转移过来的湿坯，如图1.1、图1所示。第一湿坯转移模7a下移把湿坯移交给第二湿坯转移模5a后上移复位，第二湿坯转移模5a接纳到湿坯，此时第二湿坯转移模工作面5M以及湿坯朝上；
如图1.1、图2.1、图3.1、图1、如图2、图3所示,在湿坯翻转驱动器5b的驱动下，接纳到湿坯的第二湿坯转移模5a带着湿坯上下翻转180度，完成翻转后，第二湿坯转移模工作面5M及吸附着的湿坯朝下(湿坯的网面朝上)。
如图4、图4.1所示，在第二湿坯转移装置水平驱动器6的驱动下，第二湿坯转移模5a带着完成翻转后的湿坯沿左右平移轨道8左移到可上下移动的左热压下模3Lc上方；左热压下模3Lc上移从第二湿坯转移模5a中取走湿坯后下移到位，与此同时，第一湿坯转移模7a下移到吸滤成型装置2中把湿坯从吸滤成型模具2a上吸起并上升到位。
第二湿坯转移模5a沿左右平移轨道8回到第一湿坯转移模7a的下方；第二湿坯转移模5a上下翻转180度，第二湿坯转移模工作面5M再次向上朝向第一湿坯转移模7a(如图1、图1.1所示)，第一湿坯转移模7a再次下移把湿坯移交给第二湿坯转移模5a后上移复位，第二湿坯转移模5a再次接纳到湿坯，而同时，左热压下模3Lc上移与左热压上模3La合模对湿坯进行热压干燥定型，热压干燥定型后，左热压模具开模，纸浆模塑制品在适当时候被及时送出纸浆模塑成型机。
再次接纳到湿坯的第二湿坯转移模5a，在湿坯翻转驱动器5b的驱动下，上下翻转180度，完成翻转后，第二湿坯转移模5a带着完成翻转后的湿坯沿左右平移轨道8右移到可上下移动的右热压下模3Rc上方；右热压下模3Rc上移从第二湿坯转移模5a取走湿坯后下移到位，与此同时，第一湿坯转移模7a下移到吸滤成型装置2中把湿坯从吸滤成型模具2a上吸起并上升到位。

湿坯翻转式纸浆模塑成型机按照上述步骤进行循环工作，不断生产纸浆模塑制品，纸浆模塑制品又被及时送出纸浆模塑成型机。
整个纸浆模塑制品的生产过程，吸滤成型模具2a制成的湿坯，在被第一湿坯转移模7a取走并送到第二湿坯转移模5a，又被第二湿坯转移模5a上下翻转180度后(第二湿坯转移模工作面5M及吸附着的湿坯朝下、湿坯的网面朝上)送入左热压定型装置或右热压定型装置进行热压干燥定型。实现“湿坯的网面”与“热压模具的光面”进行匹配的效果；也可实现制品壁厚均匀又容易脱模这一理想工艺效果；大大提高机器运行的稳定性、制品的质量和合格率，生产成本大幅度降低。

右热压定型装置3R含有可上下移动的右热压上模3Ra和可水平移动的右热压下模3Rc。右热压上模3Ra和右热压下模3Rc是一对相匹配的右热压模具(右热压定型模具)。右热压下模3Rc位于右热压上模3Ra下方时，右热压定型模具可以进行上下合模，制品的湿坯在右热压定型装置3R中被热压干燥定型，这个位置称为右热压工位3R.1。
如图8所示,右热压下模3Rc固定在左右平移轨道滑块9上，左右平移轨道滑块9可在左右平移轨道8上进行水平移动。在右热压下模水平驱动机构10R的驱动下，右热压下模3Rc可沿左右平移轨道8在右热压上模3Ra的下方与第一湿坯转移模7a的下方之间水平移动。
如图8所示,在吸滤成型装置2的上方有一个第一湿坯转移装置7，第一湿坯转移装置7固定在上机架1b上，第一湿坯转移装置7含有能上下移动的第一湿坯转移模7a、推动第一湿坯转移模7a上下移动的第一湿坯转移模动力传送机构7b,第一湿坯转移模动力传送机构7b的结构方式有多种，优选伺服电机驱动，也可以是油缸驱动或其它方式驱动。
第二湿坯转移装置5含有第二湿坯转移模5a、湿坯翻转驱动器5b。如图8、、图9.1、图9.2、图11、图12所示,第二湿坯转移模5a在湿坯翻转驱动器5b的驱动下可以进行上下180度翻转。第二湿坯转移模5a进行180度翻转的方式有多种，可绕轴翻转也可不绕轴翻转，作为优选方案，第二湿坯转移模5a进行的上下180度翻转，可以绕着一平行于水平面的轴线进行，即可以绕轴上下180度翻转，达到把第二湿坯转移模工作面5M从朝上翻转到朝下的目的。
如图8、图9.1、图9.2所示,在第一湿坯转移装置7的下方，第二湿坯转移装置5从第一湿坯转移模7a接纳湿坯，翻转后的湿坯也在第一湿坯转移装置7的下方被移交给左热压下模3Lc或右热压下模3Rc，这一工位称作翻转模具5a的转移工位T(也称作“T位”)。当第一湿坯转移模7a需要下移从吸滤成型模具2a中提吸湿坯时，第二湿坯转移装置5必须让出位置，向前移动，离开T位到达位于第一湿坯转移装置7前面的翻转模具5a的避让工位D(也称作“D位”)。
如图8、图9.1、图9.2、图10、图10.1所示,第一湿坯转移装置7的左侧是左热压定型装置3L，第一湿坯转移装置7的右侧是右热压定型装置3R，第一湿坯转移装置7的前面是翻转模具5a的避让工位D。
如图8、图9.1、图9.2、图10所示,作为优选方案，在第一湿坯转移装置7的前侧设置2条或2组纵向轨道4，纵向轨道4水平布置高于左右平移轨道8并与左右平移轨道8相垂直。2条或2组纵向轨道4水平设置且朝着第一湿坯转移装置7水平延伸。第二湿坯转移装置5固定在纵向轨道滑块4a上，纵向轨道滑块4a可以沿纵向轨道4前后移动。即第二湿坯转移装置5可以沿纵向轨道4在T位和D位之间移动，如图8、图9.1所示,在第一湿坯转移装置7的前侧设置有上下布置的沿竖直轨道4.1，纵向轨道4可以沿竖直轨道4.1进行上下移动。因此，第二湿坯转移模5a可以上下翻转，也可以随第二湿坯转移装置5上下移动和前后移动。
或者，如图10.1所示，第二湿坯转移装置5可以是能带动第二湿坯转移模5a上下翻转、三维移动的多自由度的机械手或机械臂与第二湿坯转移模5a的组合。多自由度的机械手或机械臂与第二湿坯转移模5a的组合也是第二湿坯转移装置5的一种结构形式，多自由度的机械手或机械臂带动第二湿坯转移模5a进行上下翻转和三维移动。多自由度的机械手或机械臂是一种可以多轴旋转也可以三维移动的通用装置，比如6轴机械手或机械臂。
左热压下模3Lc、右热压下模3Rc、第二湿坯转移装置5、第一湿坯转移装置7相互配合以实现湿坯的翻转和移送。
为了不发生动作冲突，左热压下模3Lc和右热压下模3Rc从第二湿坯转移模5a接纳到湿坯后各自回到左热压工位和右热压工位；从第一湿坯转移模7a接纳到湿坯后的第二湿坯转移模5a要先从T位移到D位进行避让，并在D位对湿坯进行上下180度翻转；而此时，第一湿坯转移模7a正好可以从吸滤成型模具2a上提取湿坯。
如图13所示，第一湿坯转移模7a从吸滤成型模具2a中提取湿坯上移到位后，左热压下模3Lc或右热压下模3Rc沿左右平移轨道8来到第一湿坯转移模7a的下方，同时，第二湿坯转移模5a从D位移回到T位，也来到第一湿坯转移模7a的下方并位于已经沿左右平移轨道8来到第一湿坯转移模7a下方的左热压下模3Lc或右热压下模3Rc上方；第二湿坯转移模工作面5M和所吸附着的湿坯朝下，第二湿坯转移模 5a带着湿坯下移，把湿坯转移到左热压下模3Lc或右热压下模3Rc，等左热压下模3Lc或右热压下模3Rc带着湿坯回到左热压工位或右热压工位后，第二湿坯转移模5a在T位上下180度翻转，第二湿坯转移模5a的工作面5M朝上，第二湿坯转移模5a上移去接纳第一湿坯转移模7a上的湿坯，从第一湿坯转移模7a接纳到湿坯后的第二湿坯转移模5a又从T位移到D位进行避让，并在D位对湿坯进行上下180度翻转。
左热压下模3Lc从第二湿坯转移模5a接纳到湿坯后移回到左热压工位3L.1，处于左热压上模3La的下方，左热压上模3La在左热压上模驱动装置3Lb的驱动下向下移动，与左热压下模3Lc进行合模，左热压模具对湿坯进行热压干燥定型；
右热压下模3Rc从第二湿坯转移模5a接纳到湿坯后移回到右热压工位3R.1，处于右热压上模3Ra的下方，右热压上模3Ra在右热压上模驱动装置3Rb的驱动下向下移动，与右热压下模3Rc进行合模，右热压模具对湿坯进行热压干燥定型。
吸滤成型浆槽中合适浓度的浆液在吸滤成型模2a中制成湿坯，当完成湿坯成型后，第一湿坯转移模7a向下移动到达吸滤成型模2a，把吸滤成型模2a中的湿坯吸起并上移到位(第一湿坯转移模完成取件)，当制成的湿坯被取走后，吸滤成型模继续吸滤浆液制成新的湿坯，并等待下一次的第一湿坯转移模取件。
在左右平移轨道8的上方、第一湿坯转移装置7的前侧设置2条或2组纵向轨道4，纵向轨道4高于左右平移轨道8呈水平布置，且朝着第一湿坯转移装置7水平延伸，并与左右平移轨道8相垂直。

(5)位于第一湿坯转移模7a下方的第二湿坯转移模工作面5M朝向第一湿坯转移模7a，第二湿坯转移模5a上移(或第一湿坯转移模7a下移)，第一湿坯转移模7a与第二湿坯转移模5a合模，第一湿坯转移模7a把湿坯移交给第二湿坯转移模5a；第二湿坯转移模5a与第一湿坯转移模7a开模，第二湿坯转移模5a下移(或第一湿坯转移模7a上移)，第二湿坯转移模5a接纳到湿坯，此时第二湿坯转移模工作面5M以及湿坯朝上；
(6)接纳到湿坯后的第二湿坯转移模5a从翻转模具5a的转移工位T移动到翻转模具5a的避让工位D，在D位第二湿坯转移模5a带着湿坯进行上下180度翻转，使第二湿坯转移模工作面5M以及所带着的湿坯朝下，同时，第一湿坯转移模7a向下移动从吸滤成型模2a中再次提取湿坯并上移到位；
(7)左热压下模3Lc和右热压下模3Rc各自在动力的驱动下，沿左右平移轨道8交替移动到第一湿坯转移模7a的下方，同时，第二湿坯转移模5a从D移回到T位，在T位，第二湿坯转移模5a带着湿坯下移到左热压下模3Lc或右热压下模3Rc，把湿坯转移到左热压下模3Lc或右热压下模3Rc后上移复位；
(8)接纳了湿坯后的左热压下模或右热压下模在动力传送机构的驱动下返回到左热压工位3L.1或右热压工位3R.1；热压合模对湿坯进行热压干燥定型,热压干燥定型后，热压模具开模，纸浆模塑制品在适当时候被被及时送出纸浆模塑成型机，同时，湿坯被移走后的第二湿坯转移模5a在翻转模具5a的转移工位T进行上下180度翻转，使第二湿坯转移模工作面5M朝上，朝向第一湿坯转移模7a；
(9)位于第一湿坯转移模7a下方的第二湿坯转移模工作面5M朝向第一湿坯转移模7a，第二湿坯转移模5a上移(或第一湿坯转移模7a下移)，第一湿坯转移模7a与第二湿坯转移模5a合模，第一湿坯转移模7a把湿坯移交给第二湿坯转移模5a；第二湿坯转移模5a与第一湿坯转移模7a开模，第二湿坯转移模5a下移(或第一湿坯转移模7a上移)，第二湿坯转移模5a接纳到湿坯，此时第二湿坯转移模工作面5M以及湿坯朝上；
(10)接纳到湿坯后的第二湿坯转移模5a从翻转模具5a的转移工位T移动到翻转模具5a的避让工位D，在D位第二湿坯转移模5a带着湿坯进行上下180度翻转，使第二湿坯转移模工作面5M以及所带着的湿坯朝下，同时，第一湿坯转移模7a向下移动从吸滤成型模2a中再次提取湿坯并上移到位；
依照上述过程循环往复，生产连续进行。不断生产纸浆模塑制品，纸浆模塑制品被及时送出纸浆模塑成型机或进入下一工序。其特点是，第一湿坯转移模(7a)把湿坯转移给第二湿坯转移模5a、第二湿坯转移模(5a)把翻转后的湿坯转移给热压下模(3c)都在第一湿坯转移模(7a)的正下方完成。
整个纸浆模塑制品的生产过程，吸滤成型模具2a制成的湿坯，第一湿坯转移模7a下移到吸滤成型模 具2a中把湿坯吸起(提取湿坯)并上移到位，左热压下模3Lc和右热压下模3Rc沿左右平移轨道8交替移动到第一湿坯转移模7a的下方接纳湿坯，这些都是现有的技术。
本实施例的特征在于：左热压下模3Lc和右热压下模3Rc沿左右平移轨道8交替移动到第一湿坯转移模7a的下方接纳湿坯，不直接从第一湿坯转移模7a接纳湿坯，而是从第二湿坯转移模5a中接纳经过翻转后的湿坯。第二湿坯转移模5a从第一湿坯转移模7a下方取走湿坯后移出第一湿坯转移模7a的下方到达D位，并在D位带着湿坯上下翻转180度，再带着翻转后的湿坯回到第一湿坯转移模7a的下方。如图13所示，与湿坯一起翻转后的第二湿坯转移模5a回到第一湿坯转移模7a的下方时，也正好是位于左热压下模3Lc或右热压下模3Rc的上方，这时，第一湿坯转移模7a下移，把翻转后的湿坯转移给左热压下模3Lc或右热压下模3Rc后上移到位，接纳了湿坯后的左热压下模或右热压下模返回到左热压工位3L.1或右热压工位3R.1，左热压定型装置和右热压定型装置对湿坯进行热压干燥定型。实现“湿坯的网面”与“热压模具的光面”进行匹配的效果。
在热压定型装置对湿坯进行热压干燥定型时，“热压模具的光面”压着材质致密平整优质的“湿坯的网面”，而让有一点柔性且容易压到湿坯各处的“热压模具的网面”去压“湿坯的毛面”。热压模具的光面可以把制品压得非常光滑，而湿坯的毛面又容易被热压模具的网面压出致密的网纹。所以制品的两面都到获得很好的加工效果，纸浆模塑制品特别是高质量的精致工业包装制品的生产难度降低了；也实现了制品壁厚均匀又容易脱模这一理想工艺效果；大大提高机器运行的稳定性和制品的质量，合格率也大大提高，生产成本可大幅度降低。

整个纸浆模塑制品的生产过程，吸滤成型模具2a制成的湿坯，在被第一湿坯转移模7a取走并送到第二湿坯转移模5a，被第二湿坯转移模5a上下翻转180度后送入热压下模，接纳了湿坯后的热压下模在动力传送机构的驱动下返回到热压工位3.1，热压定型装置对湿坯进行热压干燥定型。实现“湿坯的网面”与“热压模具的光面”进行匹配的效果。

如图17、图20所示,第二湿坯转移装置5含有第二湿坯转移模5a、第二湿坯移动架5c、第二湿坯转移装置水平驱动器6；第二湿坯转移模5a用来吸附湿坯的模具面是“第二湿坯转移模工作面”5M，本实施例中，第二湿坯转移模工作面5M始终朝下。
如图17、图20所示,在上机架的下侧从左端到右端固定着2根(或2组)左右平移轨道8，左右平移轨道8上设有可沿轨道滑动的左右平移轨道滑块9，第二湿坯转移装置5固定在左右平移轨道滑块9上，第二湿坯转移装置5通过左右平移轨道滑块9倒挂在上机架的下侧，在第二湿坯转移装置水平驱动器6的驱动下，可沿左右平移轨道8左右移动。

在第一湿坯转移模7a下移从吸滤成型模具2a中提取湿坯之前，第一湿坯转移模工作面7M应该朝下，如果第一湿坯转移模工作面7M没有朝下，那么，第一湿坯转移模7a应该进行翻转以实现第一湿坯转移模 工作面7M朝下。
如图17、图18、图19所示，湿坯在吸滤成型装置中制作完成，第一湿坯转移模工作面7M已经朝下的第一湿坯转移模7a下移把所述湿坯从吸滤成型模具2a中吸起并上移到特定的位置后，第一翻转轴驱动器7.1a驱动第一湿坯转移模7a带着湿坯作上下180度翻转，第一湿坯转移模工作面7M以及湿坯朝上(湿坯的网面朝上)。
可沿左右平移轨道8进行左右水平移动的第二湿坯转移模5a进入到第一湿坯转移模7a的上方，第二湿坯转移模工作面5M始终朝下，第一湿坯转移模7a上移，与第二湿坯转移模5a进行合模，把湿坯移交给第二湿坯转移模5a后，第一湿坯转移模下移，第二湿坯转移模5a接纳到湿坯，这一过程可对湿坯进行预整型。
湿坯朝下的第二湿坯转移模带着湿坯左移到左热压定型装置中的左热压下模的上方；同时，湿坯被移走后的第一湿坯转移模7a上下翻转180度，第一湿坯转移模工作面7M朝下。
第一湿坯转移模工作面7M朝下的第一湿坯转移模7a再次下移把所述湿坯从吸滤成型模具2a中吸起并上移到特定的位置后，第一翻转轴驱动器7.1a驱动第一湿坯转移模7a带着湿坯作上下180度翻转，第一湿坯转移模工作面7M以及湿坯朝上(湿坯的网面朝上)。
而左热压下模3Lc上移从第二湿坯转移模5a取走湿坯后下移到位(这一过程又可对湿坯进行预整型)，第二湿坯转移模5a沿左右平移轨道8右移回到第一湿坯转移模7a的上方；第一湿坯转移模7a上移，把湿坯移交给第二湿坯转移模5a后下移复位，第二湿坯转移模5a再次接纳到湿坯；而同时，左热压定型装置合模对湿坯进行热压干燥定型；
湿坯被移走后的第一湿坯转移模7a上下翻转180度，第一湿坯转移模工作面7M朝下，第一湿坯转移模7a下移把所述湿坯从吸滤成型模具2a中吸起并上移到特定的位置后，第一翻转轴驱动器7.1a驱动第一湿坯转移模7a带着湿坯作上下180度翻转，第一湿坯转移模工作面7M以及湿坯朝上(湿坯的网面朝上)；

热压上模的光面压湿坯的网面，制成干燥定型后的纸浆模塑制品，制品被送出纸浆模塑成型机，制品的两面都到获得很好的加工效果。
如图19、图20所示,第一湿坯转移装置7上设有第一湿坯转移模7a，第一湿坯转移模7a进行180度翻转的方式有多种，作为优选方案，第一湿坯转移模7a进行的上下180度翻转，可以绕着一平行于水平面的轴线进行，即可以绕第一湿坯翻转轴7.1上下180度翻转，达到把第一湿坯转移模工作面7M从朝上翻转到朝下或从朝下翻转到朝上的目的。如图17、图20所示,驱动第一湿坯转移模7a进行180度翻转的是第一翻转轴驱动器7.1a。由图可知：第一湿坯翻转轴7.1，通过轴承可转动地定位在第一湿坯移动架7c上，第一翻转轴驱动器7.1a(如带减速机的电机)的座体固定在第一湿坯移动架7c的一侧，第一翻转轴驱动器7.1a的驱动轴(如电机输出轴或减速机输出轴)与第一湿坯翻转轴7.1同轴连接；显然，湿坯翻转驱动器启动，即可驱动第一湿坯翻转轴7.1带动第一湿坯转移模7a进行180翻转。
第一湿坯转移装置7与第二湿坯转移装置5共同实现了把湿坯从吸滤成型模具到热压定型模具移送的功能，第一湿坯转移装置7与第二湿坯转移装置5之间的动作配合、左右热压下模上移从第二湿坯转移模5a取走湿坯后下移到位可实现对湿坯的两次预整形；湿坯的180度翻转，达到“热压模具的光面”去压材质致密平整优质的“湿坯的网面”的目的，而让有一定柔性且容易压到湿坯整体表面的“热压模具的网面”去压“湿坯的毛面”，制品的两面都到获得很好的加工效果，实现了双面优化。
本实施例的完整的实施过程通常是这样的：
(1)在吸滤成型模具2a的上方，对7M没有朝下的第一湿坯转移模7a进行翻转归位，使第一湿坯转移模工作面7M朝下，然后第一湿坯转移模7a下移，把湿坯从吸滤成型模具2a中吸起并上移到特定的位置后，第一湿坯转移模7a带着湿坯作上下180度翻转，第一湿坯转移模工作面7M以及湿坯朝上(湿坯的网面朝上)；
(2)湿坯被取走后的第二湿坯转移模5a沿左右平移轨道8移动到第一湿坯转移模7a的上方；第一湿坯转移模7a上移把湿坯移交给第二湿坯转移模5a，第一湿坯转移模7a下移继续实施步骤(1)的动作，而接纳到湿坯的第二湿坯转移模5a带着湿坯沿左右平移轨道8左移到可上下移动的左热压下模3Lc上方；左热压下模3Lc上移从第二湿坯转移模5a取走湿坯后下移到位；

第一湿坯转移模7a再次上移把湿坯移交给第二湿坯转移模5a后下移继续实施步骤(1)的动作，
而同时，左热压下模3Lc上移与左热压上模3La合模对湿坯进行热压干燥定型，热压干燥定型后，左热压模具开模，纸浆模塑制品在适当时候被及时送出纸浆模塑成型机；
(4)接纳到湿坯的第二湿坯转移模5a右移到可上下移动的右热压下模3Rc上方；右热压下模3Rc上移从第二湿坯转移模5a取走湿坯后下移到位；
(5)湿坯被转移走后的第二湿坯转移模5a回到第一湿坯转移模7a的上方；
第一湿坯转移模7a再次上移把湿坯移交给第二湿坯转移模5a后下移继续实施步骤(1)的动作，
而同时，右热压下模3Rc上移与右热压上模3Ra合模对湿坯进行热压干燥定型，热压干燥定型后，右热压模具开模，纸浆模塑制品在适当时候被及时送出纸浆模塑成型机。
湿坯翻转式纸浆模塑成型机按照上述步骤(2)-(5)进行循环工作，不断生产纸浆模塑制品，纸浆模塑制品又被及时送出纸浆模塑成型机。
上述动作顺序可以有所调整而不同。但是都会经过以下动作，第一湿坯转移装置的第一湿坯转移模(7a)，先把湿坯从吸滤成型模具2a中提取出来，再进行上下翻转180度，接着把翻转后的湿坯转移给第二湿坯转移模(5a)；第二湿坯转移装置(5)沿左右平移轨道(8)从第一湿坯转移装置上方水平移动到热压下模(左热压下模或右热压下模)的上方，可上下移动的热压下模(左热压下模或右热压下模)上移到第二湿坯转移模(5a)中提取所述湿坯，以实现上下翻转后的湿坯被移送到热压定型装置。
整个纸浆模塑制品的生产过程，吸滤成型模具2a制成的湿坯，在被第一湿坯转移模7a取走并翻转后(第一湿坯转移模工作面7M及吸附着的湿坯朝上、湿坯的网面朝上)，再移送到第二湿坯转移模5a，又被第二湿坯转移模5a送入左热压定型装置或右热压定型装置进行热压干燥定型。
实现对湿坯的两次整形；也实现了“湿坯的网面”与“热压模具的光面”进行匹配；又可实现制品壁厚均匀又容易脱模这一理想工艺效果。大大提高机器运行的稳定性、制品的质量和合格率，生产成本大幅度降低。
