At present, in the prior art, when a plastic wire drawing machine works, the wire manufactured by the plastic wire drawing machine needs to be guided by external force at first, and the wire cannot be curled, if the plastic wire drawing machine is used for automatic production, the manufactured wire cannot be used.
Disclosure of Invention
The utility model aims to provide a nozzle structure for a plastic extruder, which has a simple structure, can ensure that extruded silk threads cannot curl without guiding silk threads manufactured by the plastic wire drawing machine through external force.
The purpose of the utility model is realized in the following way:
the utility model provides a nozzle structure for plastics extruder, includes the nozzle that sets up at plastics wire drawing machine discharge end, the upper end of nozzle is provided with the threaded connection portion that conveniently is connected with plastics wire drawing machine, be provided with the extrusion passageway in the nozzle, the extrusion passageway is including gathering portion, transition portion and extrusion part, gathering portion is close to plastics wire drawing machine discharge end setting, transition portion is located between gathering portion and the extrusion part, gathering portion and transition portion all are the taper hole structure, the extrusion part is cylindrical hole structure.
In the nozzle structure for the plastic extruder, the taper of the converging part is 50-54 degrees.
In the nozzle structure for the plastic extruder, the taper of the transition part is between 7 and 9 degrees.
In the above nozzle structure for a plastic extruder, the height H of the extrusion part is smaller than the height H of the convergence part, which is smaller than the height a of the transition part.
In the nozzle structure for the plastic extruder, the height h of the converging part is 6-8mm.
In the nozzle structure for the plastic extruder, the height a of the transition part is 50-54mm.
In the nozzle structure for the plastic extruder, the height H of the extruding part is 3-5mm.
Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:
the extrusion channel of the nozzle is of a three-section structure, the plastic wire drawing machine melts raw materials into plastic melt, the plastic melt gradually flows towards the nozzle through screw extrusion, the plastic melt enters the transition part after being converged at the converging part, the inner space of the transition part gradually becomes smaller from top to bottom, finally, the plastic melt enters the extrusion part to be extruded, the discharge end of the nozzle is arranged downwards, and the gradually formed plastic melt automatically flows downwards by virtue of natural attractive force and extrusion force of the screw.
