Description

同向锥形双螺杆ABS造粒机
技术领域
本实用新型涉及一种ABS造粒设备，特别是同向锥形双螺杆ABS造粒机。
背景技术
目前进行ABS(丙烯腈-丁二烯-苯乙烯共聚物)造粒生产的造粒机主要有平行双螺杆造粒机和单螺杆造粒机。单螺杆造粒机因为具有挤出力大的优点，所以被广泛应用在塑料造粒生产中。由于受到加工工艺的影响，单螺杆造粒机螺杆的有效长径比受到了一定的影响，所以影响了原料的塑化性。同时由于目前平行双螺杆造粒机螺杆转速很高，所以存在能耗高、齿轮箱易损坏等缺点。
发明内容
为了解决目前平行双螺杆造粒机和单螺杆造粒机存在能耗高、产量低、塑化性能差等问题，本实用新型提供了一种塑化性能好、产量高、能耗低的同向锥形双螺杆ABS造粒机。
本实用新型的同向锥形双螺杆ABS造粒机包括切粒装置、锥形螺杆、排气口、机筒、加热圈、喂料装置、分配箱、减速传动箱、联轴器、驱动电机、机架，其特征在于两根锥形螺杆在机筒内同方向旋转，每根螺杆的有效长径比为30～80∶1，分配箱中与两根锥形螺杆相连接的主动齿轮和从动齿轮上方或下方设有中间齿轮，锥形螺杆转速介于0～160rpm。
本实用新型的同向锥形双螺杆ABS造粒机由于具备了平行同向双螺杆造粒机螺杆同向旋转的螺杆结构，因此具备了塑化混炼性能好、螺杆转速高、长径比大等优势。工作时，驱动电机通过联轴器连接到减速传动箱，减速传动箱连接分配箱中的主动齿轮，通过分配箱中的主动齿轮带动中间齿轮，中间齿轮再带动从动齿轮，从而使与主动齿轮和从动齿轮连接的两根锥形螺杆在机筒内同方向旋转，将由喂料装置输送的ABS原料熔融、混炼、塑化、排气，最后经切粒装置进行切粒。
本实用新型的有益效果是：
由于本实用新型的同向锥形双螺杆ABS造粒机同时具备了锥形双螺杆造粒机和平行同向双螺杆造粒机的全部优点，具有挤出力大、能耗低、塑化混炼性能好、螺杆转速高、长径比大、产量高等优势，是一种高产量、低能耗、低成本的新型ABS造粒设备。
附图说明
下面结合附图对本实用新型作进一步的说明。
附图1为本实用新型的结构示意图。
附图2为本实用新型实施例的同方向旋转锥形螺杆结构示意图。
附图3为本实用新型实施例的分配箱齿轮结构示意图。
具体实施方式
如图1～3所示，本实施例的同向锥形双螺杆ABS造粒机包括切粒装置1、锥形螺杆2、排气口3、机筒4、加热圈5、喂料装置6、分配箱7、减速传动箱8、联轴器9、驱动电机10、机架11，两根锥形螺杆2-1和2-2在机筒4内的同方向旋转。
驱动电机10通过联轴器9连接到减速传动箱8，减速传动箱8连接分配箱7中的主动齿轮12，通过分配箱7中的主动齿轮12带动中间齿轮13，中间齿轮13再带动从动齿轮14，从而使与主动齿轮12和从动齿轮14连接的两根锥形螺杆2-1和2-2在机筒4内同方向旋转。喂料装置6和与机筒4内腔相通，加热圈5包覆在机筒4的外部。两根锥形螺杆2-1和2-2在机筒4内同方向旋转时，将由喂料装置6输送的原料熔融、混炼、塑化、排气，最后经切粒装置1进行切粒。本实施例中的技术参数：螺杆小头直径为65mm，螺杆有效长度为2780mm，螺杆有效长径比为43∶1，螺杆转速为0～140rpm。
上述实施例及附图是对本实用新型的进一步详细说明，但本实用新型要求保护的范围并不局限于实施例中所描述的范围。凡采用等同替换或等效变换形成的技术方案，均落在本实用新型要求的保护范围。
