Description

一种双螺旋杆造粒机的螺旋输送机构
技术领域
本实用新型涉及造粒机输送领域，具体为一种双螺旋杆造粒机的螺旋输送机构。
背景技术
双螺杆造粒机主要用于橡塑和工程树脂的填充、共混、改性、增加、氯化、聚丙烯和高吸水性树脂的加工，平行双螺杆造粒机的料筒和螺杆均按积木式原理设计，可按需要进行不同组合，采用电加热和水冷却自动控制机筒温度，并配有强制喂料，真空排气和不停车换网装置，双螺杆采用变频调速、交流电机驱动或直流调速、直流电机驱动，减速和双螺杆传动在同一箱体之内，外形尺寸紧凑，采用装有剪切销的安全联轴器，可以保护螺杆和传动箱不因超负荷而损坏：
例如，申请号为201420416036.3，专利名称为一种双螺杆造粒机的螺旋输送机构的实用新型/实用新型专利：
其通过转盘、与转盘联动连接的第一电机、与第一螺杆联动连接的第二电机、与第二螺杆联动连接的第三电机，第一螺杆和第二螺杆轴向固定、周向旋转地设于转盘同侧，从而使得在螺旋输送的时候能够均匀的搅拌。
但是，现有的利用拉伸膜包装货物的方法存在以下缺陷：
(1)由于物料在造粒机中存在一定的形态变换过程，在进入双螺杆螺旋输送时，需要具备一定的熔融状态，现有的螺旋输送装置，都是在机筒内形成熔融状态，从而增加了输送机构的输送压力；
(2)使得熔融状态是内部的气泡尽可能的少，该第一螺杆和第二螺杆只能通过增加其搅动时间，使得充分搅拌，螺旋杆的结构过于单一，在搅拌的流动过程中容易出现死角，位于螺旋杆中间部分物料很难被充分搅拌，间断式螺旋桨叶使得螺旋杆的轴向力过大，容易造成螺旋杆损伤，在挤出的质量上难以保证，螺杆的螺旋状态也不利于气体的逸出。
发明内容
为了克服现有技术方案的不足,本实用新型提供一种双螺旋杆造粒机的螺旋输送机构，能有效的解决背景技术提出的问题。
本实用新型解决其技术问题所采用的技术方案是：
一种双螺旋杆造粒机的螺旋输送机构，包括底座、以及安装在底座上的电机室，所述电机室连接有混料装置，所述混料装置连接有出料机筒，所述混料装置顶部设置有预热装置，所述预热装置顶部倾斜安装有投料装置，所述投料装置包括送料壳体和竖直安装在送料壳体表壁的料斗，所述送料壳体内部设置有料轴杆，且所述料轴杆的杆身上设置有偏心轮桨叶和单片螺旋桨叶；
所述混料装置内部设置有主轴杆，且所述主轴杆的杆身上设置有混送料桨叶和逸气搅拌桨叶，所述主轴杆固定连接有出料机筒内部设置的锥形双螺杆，所述锥形双螺杆一端固定连接有锥齿轮盘，所述锥齿轮盘固定连接有前轴杆，且所述前轴杆的杆身上设置有平型螺旋叶，所述前轴杆设置在出料机筒内部设置的后料腔内部。
进一步地，所述预热装置包括接料圈管，所述接料圈管和送料壳体连接处内部设置有管垫圈，且所述管垫圈中间设置有轴承，所述接料圈管内部设置有涡流绕线。
进一步地，所述逸气搅拌桨叶包括内圈片，以及套装在内圈片上的外圈片，所述外圈片表面环形均匀设置有豁孔，所述豁孔通过内逸孔链接有环形设置在内圈片上的切割圈。
进一步地，所述偏心轮桨叶为椭圆型圆盘，且相邻两个偏心轮桨叶的偏心方向相反。
进一步地，所述主轴杆和锥形双螺杆连接处设置有内架圈。
进一步地，所述料轴杆末端和轴承连接在一起。
与现有技术相比，本实用新型的有益效果是：
(1)本实用新型的螺旋输送机构由主轴杆和锥形双螺杆，以及前轴杆连接组合而成，在主轴杆上设置混送料桨叶和逸气搅拌桨叶，将进入机筒的物料进行初步的混合熔融，同时通过逸气搅拌桨叶上的切割圈对物料进行充分的切割，搅拌，将熔融状态的物料中的气体切破，通过内逸孔进入豁孔中，通过机筒本身的真空逸气装置进行排气，同时豁孔本身具备剪切和导气的作用，同时使得搅拌更加均匀，在初步熔融状态后就对物料进行截流排气，避免了携带气体的物料进入机筒中，从而在机筒中形成较大的压力，使得挤出的物料质量下降，且形成隔断，进入机筒后的物料通过锥形双螺杆的挤压输送，最后通过锥齿轮盘的最后剪切，截流，后通过平型螺旋叶进行出料输送，后料腔的腔室口小于锥形双螺杆安装的腔室，从而使得物料被短暂滞留在锥形双螺杆上，从而达到充分的搅拌目的；
(2)本实用新型的投料装置和混料装置为螺旋输送机构提供了前提保障，通过投料装置中的偏心轮桨叶对物料进行充分的搅拌剪切，使得物料颗粒更小，便于后续的加工，通过单片螺旋桨叶进行螺旋输送至预热装置，通过涡流绕线能够快速的对通过的物料进行预热，陶瓷材质的接料圈管能够有效的进行热量传递，从而降低机筒本身的加热状态，延长螺旋杆的使用寿命。
