Abstract
The invention relates to a plastic extruding machine for producing a chair, and belongs to the field of extrusion manufacturing equipment of common accessories of revolving chairs. The plastic extruding machine for producing the chair comprises a pre-extruding machine and a sub-extruding machine which is connected with the pre-extruding machine in parallel, wherein an isthmus faucium section is arranged between the pre-extruding machine and the sub-extruding machine. The plastic extruding machine adopts a parallel structure of the pre-extruding machine and the sub-extruding machine; and the pre-extruding machine is connected with the sub-extruding machine through the isthmus faucium section, so that a plastic raw material is extruded in a two-stage manner through the isthmus faucium section after being pre-extruded in a heated molten state, and then is extruded from an extrusion head, thus the material is relatively evenly extruded; when the material passes through the isthmus faucium section, the flow rate of the material significantly becomes slow from fast and then becomes fast; excessive bubbles mixed into the material are driven away by the material; and the residual required bubbles can be relatively evenly dispersed into the molten material, therefore, the problem that revolving chair accessories prepared by the plastic extruding machine are low in compressive strength or easy to crack due to the bubbles is avoided.
