具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1-6，本发明实施例中，一种机油滤纸制作工艺，包括下列步骤：
步骤一：通过熔喷机构熔喷得到无纺布层；
步骤二：在无纺布层未完全凝固定型时，通过洒布机构向无纺布层上洒布吸水珠21和磁粉；
步骤三：通过冷却机构对无纺布进行冷却定型；
步骤四：通过开孔机构在完成降温定型的无纺布上开设通孔，得到无纺布中心层20；
步骤五：在无纺布中心层20的两侧覆盖过滤纸23，并在过滤纸23一侧涂覆防护树脂24，得到机油滤纸。
输送机构带动熔喷得到的无纺布层移动，洒布机构、冷却机构、开孔机构均设置于无纺布层移动路径上方；输送机构包括输送台架1，输送台顶部的中心安装有输送带2，熔喷机构和洒布机构均设置于防护箱3内，并通过分隔件相互阻隔，防护箱3设置于输送台架1顶部的一端，且防护箱3底部与输送台架1的两侧固定连接，分隔件包括两个分隔板4，两个分隔板4将防护箱3内部空间分隔为三个工作腔，以此避免热熔喷涂及洒布操作相互干扰，熔喷机构包括熔喷头5，熔喷头5的输出端朝向输送带2的顶面，熔喷头5的输入端与通过导料管与外接热熔设备的输出端固定连接，通过熔喷头5将熔融状态的无纺布材料喷涂至输送带2的表面，使其在输送过程中逐渐冷却定型，形成无纺布层，在具体实施时，在输送带2的端部，通过外设的分离取料机构，将加工得到的无纺布中心层20与输送带2分离；
洒布机构包括珠体洒布器6和粉料洒布器7，防护箱3顶部的两侧均开设有上料口，两个上料口的底部分别与珠体洒布器6的进料口和粉料洒布器7进料口对应设置，两个上料口的内壁均铰接有盖板8，通过设置上料口和盖板8，使得对珠体洒布器6和粉料洒布器7的补料操作更加方便；熔喷头5、珠体洒布器6和粉料洒布器7分别设置于三个工作腔的内部；通过珠体洒布器6和粉料洒布器7分别进行吸水珠21和磁粉的洒布，由于洒布时无纺布还未完全冷却定型，因此洒布出的吸水珠21和磁粉能够很好的与无纺布粘连嵌合，不易分离。
通过调节件对熔喷机构和洒布机构的高度进行调节，调节件包括三个滑动架9，三个滑动架9的内壁均滑动连接有滑动板10，三个滑动板10的一侧分别与熔喷头5、珠体洒布器6和粉料洒布器7固定连接，滑动架9的中部螺纹连接有锁定螺栓，锁定螺栓的一端与滑动板10抵紧接触；使得熔喷头5、珠体洒布器6和粉料洒布器7三者的输出端与输送带2的间距可调，使得熔喷和散布的密度可调，使用灵活性更高。
冷却机构通过向无纺布层吹送气流实现对无纺布层的冷却，通过过滤件对进入冷却机构的空气进行过滤，通过冷却件对吹送的气流进行降温；冷却机构包括冷却箱11，冷却箱11内壁的中部固定连接有冷却风扇12，冷却箱11的顶部开设有过滤口，过滤件包括过滤网13，过滤网13固定连接于过滤口的内壁，冷却件包括制冷管14，制冷管14的中部弯曲盘绕设置与固定连接于冷却风扇12的下方，制冷管14的一端与外接制冷设备的输出端固定连接；通过冷却机构对无纺布进行快速的冷却定型，方便后续的开孔等加工操作。
开孔机构通过驱动开孔转辊15转动，利用开孔转辊15上开孔针17对无纺布层进行开孔操作；开孔机构包括转辊架16，转辊架16的内部转动连接有开孔转辊15，开孔转辊15的顶部固定连接有若干个均匀分布的开孔针17。
在进行开孔操作的同时，通过限位件对无纺布层进行限位，限位件包括两个限位卡板18，且两个限位卡板18对称设置并与转辊架16内壁两侧固定连接，两个限位卡板18的内壁均固定连接有若干个限位滚轮19，通过限位滚轮19对无纺布进行按压，避免开孔针17的开孔操作将无纺布牵拉带起，导致无纺布翻转折叠，影响后续加工。
防护树脂24包括以下重量份的原料：酚醛树脂20-30份、聚丙烯酸酯5-10份、聚醋酸乙烯酯乳液2-5份、抗油剂0.5-1.5份、抗氧化剂1-2份。
本工艺制备得到的机油滤纸，包括无纺布中心层20，无纺布中心层20的内部嵌设有吸水珠21和磁粉，无纺布中心层20的中部开设有通口22，无纺布中心层20的两侧均固定连接有过滤纸23，两个过滤纸23的一侧均涂覆有防护树脂24；通过设置无纺布中心层20，提高机油滤纸整体的结构强度和耐水解能力，通过设置吸水珠21，减少两侧过滤纸23吸水潮解的概率；通过添加磁粉，提高机油滤纸对机油中铁磁性杂质的过滤吸附能力；通过在无纺布上开设通口22，提高机油的通过效率，减小因设置无纺布中心层20对机油过滤造成的阻碍。
本发明的工作原理：首先通过熔喷机构将无纺布原料熔喷至输送带2上，输送带2带动未完全凝固定型的无纺布经过珠体洒布器6和粉料洒布器7，由珠体洒布器6和粉料洒布器7分别向无纺布层上洒布吸水珠21和磁粉；而后输送带2继续带动无纺布移动至冷却箱11内，冷却风扇12启动箱无纺布上吹送气流，气流通过制冷管14后被降温，降温后气流对无纺布材料进行冷却定型；
冷却定型后的无纺布在通过转辊架16时，通过两个限位滚轮19对其进行按压限位，开孔转辊15转动，带动开孔针17在无纺布上开设出通口22；得到无纺布中心层20；通过外设的分离取料机构，将无纺布中心层20与输送带2分离；通过外设其他设备在无纺布中心层20的两侧覆盖过滤纸23，并在过滤纸23的一侧涂覆防护树脂24，得到机油滤纸。
以上所述，仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭示如上，然而并非用以限定本发明，任何本领域技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案内容，依据本发明的技术实质对以上实施例所作的任何简介修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
