一种稳定型塑料挤出机,旨在提供一种使机筒更稳定的塑料挤出机,其技术方案要点是机筒内设置有螺杆和轴套,螺杆套设于轴套内,螺杆包括加热段、压缩段和计量段,加热段、压缩段和计量段对应的轴套外侧设置有钢索减震结构,钢索减震结构套设与轴套外周且与轴套固定连接,通过采用上述技术方案,避免了直接在机架上加重物稳定机筒,减轻了机架的载重,保护机架不被损坏,且在塑料挤出机搬运时不会有附加累赘,另外,钢索减震结构不但可以达到相同的保持机筒稳定,减少噪音的 A stable plastic extruder is intended to provide a plastic extruder which makes the barrel more stable. The technical proposal of the invention is that the barrel is provided with a screw and a sleeve, the screw is sleeved in the sleeve, and the screw comprises The heating section, the compression section and the metering section, the heating section, the compression section and the metering section are respectively provided with a steel wire rope damping structure on the outer side of the sleeve, the steel wire shock absorption structure is sleeved on the outer periphery of the steel sleeve and fixedly connected with the sleeve, The above technical solution avoids directly stabilizing the barrel by adding weight to the rack, reduces the load of the rack, protects the rack from being damaged, and does not have additional cumbersomeness when the plastic extruder is handled. In addition, Not only can the seismic structure achieve the same level of barrel stability and noise reduction
