Description

A kind of Novel machine head of extruding machine

Technical field

The utility model relates to a kind of cross-head, is that a kind of plastic melt uniform and stable in head flows and the cross-head extruded smoothly.

Background technology

Flourish along with China's plastics machinery industry, the expansion of the range of application of plastic products, higher to the requirement of extrusion technology.In whole extrusion molding process, the design entering process that extrusion die extrudes and cross-head with the plasticizing process of plastics in extrusion main unit and fused materials is the most key.Extrusion die is also known as cross-head, and plastics are becoming molten state after screw rod and barrel, then is plastified further by cross-head and become uniform melt, and is shaped to required article shape by head.In the overall structure of extruder, head should match with main frame, even otherwise main frame of good performance, if coordinating with it without corresponding head is be difficult to produce high-quality product.So the design quality of extrusion die will directly affect the performance of extruder.Most of heads that current China produces adopt the shortcoming of angle coupling to be that sizing material flow velocity is uneven, enter the micelle track route after head different, the micelle of outer gear is little by pressure, flow velocity, in something or somebody to fall back on, the micelle pressurized of gear is large, flow velocity is fast, the pressure differential on two limits easily makes core produce skew, and micelle flow velocity easily produces incipient scorch slowly, improves between sizing material ingress engine and avoids dead angle to become matter of utmost importance, therefore, for the problems referred to above, a kind of Novel machine head of extruding machine is proposed.
