PVC extruder

Abstract

The invention provides a PVC extruder and relates to the field of extruders. The PVC extruder comprises a machine table board, a control panel, a device box, an air dispersing box, an extrusion connecting column, an inverted connecting body, a fixed plate, an access door, a base, an air dispersing groove, an extruding body and an extruding head, wherein an expanding movable groove is fixedly inlaidin the inner side surface of the extruding head; an expanding movable strip is connected with the inner side of the expanding movable groove in a telescopic manner; a built-in hollow column is fixedly connected with the middle of the inner side of the extruding head; and the outer side surface of the built-in hollow column is not in contact with the inner side surface of the extruding head. In the PVC extruder, the expanding movable strip enables the surface of a PVC pipe to have a groove effect when the extruder is operated; a bulged sleeve is matched with the expanding movable strip to process a groove in the PVC pipe when the expanding movable strip machines the surface of the PVC pipe; a telescopic column enables the expanding movable strip to have a telescopic effect so as to adjustthe depth of the groove of the PVC pipe.

Description

technical field [0001] The invention relates to the field of materials, in particular to an extruder. Background technique [0002] Raw materials, that is, materials, are the general term for those substances that humans use to manufacture objects, devices, components, machines or other products. Materials are substances, sometimes called raw materials, but not all substances can be called materials. Such as fuels and chemical raw materials, industrial chemicals, food and pharmaceuticals are generally not considered materials. [0003] Extruder, the main machine is an extruder, which consists of an extrusion system, a transmission system and a heating and cooling system. Plastic extruder is also a kind of plastic machinery. According to the angle between the flow direction of the head and the center line of the screw, the extruder divides the head into an oblique head (the included angle is 120°) and a right-angle head. The shell of the machine head is fixed on the machi...
