Abstract

The invention provides an extrusion machine head. The extrusion machine head is arranged on an extrusion forming device, and comprises a rear machine head, a front machine head, a chuck assembly, a connecting rod assembly and a driving assembly; the rear machine head is arranged on the extrusion forming device; the front machine head is detachably connected with the rear machine head; the rear machine head is surrounded by the chuck assembly, and the chuck assembly is provided with a first position for locking the front machine head and the rear machine head and a second position for unlockingthe front machine head and the rear machine head; the connecting rod assembly is connected with the chuck assembly so as to change the position of the chuck assembly through the conduction of the connecting rod assembly; and the driving assembly is connected with the connecting rod assembly so as to control the conduction direction of the connecting rod assembly. The extrusion machine head can beused for effectively solving the problems that in the prior art, a chuck needs to be manually operated, locking and unlocking are difficult, and the safety is poor.

Description

technical field [0001] The present invention relates to the technical field of polymer material processing machinery, in particular to an extruder head. Background technique [0002] As a key device for extrusion molding of polymer materials, the die head directly affects the quality of the extruded product. Generally speaking, the structure of the head requires stable extrusion pressure and flow rate, and reliable and convenient operation. At present, the design of the internal flow channel of the traditional die is relatively simple, and there are problems of unstable extrusion pressure and flow rate, especially when extruding products with a certain width. There are various locking methods in the structure of the conventional machine head. The machine head using two chucks as the locking parts is also common, but the fastening method of screw or screw with nut is often used. The process convenience and safety performance is poor. [0003] Such as Figure 7 and 8 As sh...
