The utility model provides a new type of single screw extruder, which comprises a base, a heating chamber which is arranged on the base, the heating chamber is provided with a fixed barrel, the barrel of the rear side is connected with the charging barrel, the barrel is rotatably provided with a screw, the base is also provided with a motor and gear box, the motor is connected to the input shaft of the gear box the screw end is connected to the output shaft of the reduction box; the middle rod screw with a pointed convex side and flat top side, top to the flat side from the pointed convex side of the rotating shaft, the distance between the side wall and the screw rod body gradually becomes smaller. When the material is transported to the middle of the screw, the material has formed part of the molten state, due to the middle of the screw rod has pointed convex side and a flat side, the side of the pole body wall and the distance between the screw rotating shaft becomes smaller, so that when the rotation of the screw, the screw between the central spiral groove and the barrel wall space change, thereby squeezing in the spiral groove of the material, the material is more evenly mixed.
【技术实现步骤摘要】
一种新型单螺杆挤出机
本技术涉及一种色母粒生产设备,具体涉及一种新型单螺杆挤出机。
技术介绍
单螺杆挤出机作为一种常见的挤出机设备,用于塑料加工行业,其包括加料装置、料筒、螺杆、机头以及口模等。螺杆用于将物料压缩至熔融状态并传送物料。现有技术中的螺杆的杆体呈直柱状,其对熔融状态的物料的搅拌作用不足,导致熔融物料的混合效果不佳。
技术实现思路
针对现有技术的不足,本技术的目的是提供一种新型单螺杆挤出机,其能够使熔融物料的混合更均匀。为了解决上述技术问题,本技术所采用的技术方案是:本技术提供的新型单螺杆挤出机,包括基座,设于基座的加热室,加热室内固定地设有料筒,料筒的尾部的上侧连接有加料桶,料筒可转动地穿设有螺杆,基座还设有电机及减速箱,电机连接于减速箱的输入轴,螺杆的尾端连接于减速箱的输出轴;螺杆的中段的杆体具有尖凸侧和扁平侧,自尖凸侧的顶部至扁平侧的顶部,杆体的侧壁与螺杆的转动轴之间的距离逐渐变小。具体地,尖凸侧与扁平侧分别位于杆体的相对两侧。具体地,相邻的三个螺旋槽所对应的杆体的尖凸侧的朝向依次相差90°。本技术的有益效果在于:当物料输送至螺杆的中部时,物料已经部分形成熔融状态,由于螺杆的中段的杆体具有尖凸侧和扁平侧,且自尖凸侧的顶部至扁平侧的顶部,杆体侧壁与螺杆转动轴之间的距离逐渐变小,使得当螺杆转动时,螺杆中部的螺旋槽与料筒内壁之间的空间产生变化,从而挤压处于该螺旋槽内的物料,使得该物料被混合得更均匀。附图说明图1为本技术的新型单螺杆挤出机的立体图;图2为本技术的新型单螺杆挤出机半剖切视图的局部视图;图3为图2中D处的局部放大视图;图4为图3中A-A截面 ...
