Abstract

本实用新型公开了一种保证原料合理进料速度的机筒，包括进料段、塑化段和挤出段，所述机筒位于进料段的内壁上沿圆周方向上设置有若干条槽。本实用新型的优点是：在机筒进料段内壁上设置槽之后，增加了料进入机筒后与螺杆的摩擦力，使得料不容易打滑，保证了料前进的速度，从而不影响料的塑化效果。

Description

机筒
技术领域
本实用新型涉及到一种机筒。
背景技术
挤出机是塑机行业中一种常用的设备，而机筒则是挤出机上的一个重要部件。通常的机筒进料段内壁是光滑的，但是在实际使用的时候，发现料在进入到进料段时容易打滑，对料的前进带来了一定的影响，比如料的塑化程度。
实用新型内容
本实用新型所要解决的技术问题是：提供一种保证原料合理进料速度的机筒。
为解决上述技术问题，本实用新型采用的技术方案为：一种机筒，包括进料段、塑化段和挤出段，所述机筒位于进料段的内壁上沿圆周方向上设置有若干条槽。
所述槽宽2～3mm，槽深2.5～3mm。
本实用新型的有益效果是：在机筒进料段内壁上设置槽之后，增加了料进入机筒后与螺杆的摩擦力，使得料不容易打滑，保证了料前进的速度，从而不影响料的塑化效果。
附图说明
图1是本实用新型机筒结构图。
图中：1、进料段，2、塑化段，3、挤出段，4、槽。
具体实施方式
下面结合附图，详细描述本实用新型的具体实施方案。
如图1所示，本实用新型所述的机筒，包括进料段1、塑化段2和挤出段3，所述机筒位于进料段1的内壁上沿圆周方向上设置有若干条槽4。其中，所述槽宽2～3mm，槽深2.5～3mm。
经过实践证明，在机筒进料段1内壁上设置槽4之后，增加了料进入机筒后与螺杆的摩擦力，使得料不容易打滑，保证了料前进的速度，从而不影响料的塑化效果，即使是碰上复杂的料，如容易塑化的薄膜和性能差、不容易塑化的PE、PP等塑料及橡胶，都可以保证料的合理前进速度。

Claims (2)

1.机筒，包括进料段、塑化段和挤出段，其特征在于：所述机筒位于进料段的内壁上沿圆周方向上设置有若干条槽。
2.根据权利要求1所述的机筒，其特征在于：所述槽宽2～3mm，槽深2.5～3mm。
