Abstract

The invention provides an adjustable machine head of a plastic extruding machine. The adjustable machine head comprises a machine head body and an adjusting element, wherein a material passing hole is formed in one end of the machine head body, a connecting hole is formed in the other end of the machine head body and is communicated with the material passing hole, and the connecting hole and the material passing hole share one central line; threads are formed in the connecting hole; a discharging hole is further formed in the machine head body, is communicated with the material passing hole and is vertical to the material passing hole; the adjusting element comprises a connecting part; an adjusting part is arranged on one side of the connecting part, the connecting part is provided with external threads, the external threads are matched with internal threads of the connecting hole, the adjusting element is in threaded connection with the machine head body, and the adjusting part is arranged in the material passing hole; a sealing ring is arranged between the adjusting part and the machine head body. The adjustable machine head is simple in structure and relatively strong in practicability; by virtue of the adjustable machine head of the plastic extruding machine, the thickness requirement on membrane spraying of a metal wire is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of extruder production, and in particular relates to an adjustable head of an extruder. Background technique [0002] In the existing metal products, especially in the field of metal pipelines, it is necessary to spray plastic films such as polyethylene on the surface of the metal wires. The spray film on the metal wires is generally completed by an extruder, and the liquid spraying raw materials enter the extruder. After the feed pipe of the feed pipe, the feed screw is used to convey the spraying material to the machine head provided at the end of the feed pipe, and the raw material is finally sprayed onto the wire by the discharge port of the machine head. In the prior art, the discharge port of the machine head It is non-adjustable, and the flow rate of the outlet is controlled by the screw. In actual production, the control effect of the screw on the flow is not good, so the thickness of the wire spray ...
