Vad är den specifika produktionsprocessen för plast extruderingsutrustning

Nearly twenty years ago, as we know, feeding into extruders was usually done manually, and people struggled to pack or box pellets from somewhere into the hopper of the extruder. Plastic extruder manufacturers have learned that with the introduction of proactive skills in plastic processing, people can be freed from heavy physical labor and dusty environments. The tasks that were originally completed manually are now actively completed by Transportutrustning och andra medel .

Plastic extrusion equipment is a common type of equipment used to produce plastic products. Many of the plastic products we commonly see are produced by plastic extruders. When producing plastic products, we need to heat up the screw of the plastic extruder through a heating system. Only when the temperature of the equipment rises enough to plasticize the plastic raw materials can the equipment be started for feeding. The plastic particles enter the screw barrel through the feeding system and are mainly processed by the screw at the screw barrel and extruded to the mold head for molding. During the entire production process, the screw is driven by the power system and transmission system to roll and compact the raw materials around the screw barrel. So the fundamental structure of a plastic extruder consists of a temperature control system, a screw cylinder, a transmission system, a power system, and an extruder die. Due to the different varieties of plastic products produced, the configuration of the extruder used in production is also different. We need to choose based on the actual production situation of the product. There are many products that can be extruded by common plastic extruders. As a molding host, there are thousands of products produced, such Som olika typer av tätningsremsor, plaströr, plasttrådar och plastplåtar, som alla extruderas av plastextruder . andra plastextruder kan också användas som Auxiliary -maskiner under produktionen av vissa produkter .} när de producerar meltblown fabrics och andra plastprodukter med mögelprocesser, vi ofta användar plastiska utrustning {}} när du producerar meltblown fabrics och andra plastprodukter med mögelprocesser, vi ofta användare plastiska utrustning {}}}}}}}}}}}}}}}}}}}}}}}}}}})

The twin-screw plastic extruder consists of five parts: the kneading system (screw and barrel), the control system, the heating and cooling structure, the transmission structure (bearings, gearbox, and motor), and the feeding system. Unlike the single screw plastic extruder, the twin-screw plastic extruder has two screws inside the barrel, and the feeding part uses a screw to force direct feeding to the fat . Specifikationerna och placeringen av skruvlagren är relativt komplexa .}

1, knådesystem:

1. Barrelstruktur:

A type of golden barrel with properties such as not afraid of hemp, heat, and clock. The combination of the barrel and screw achieves the crushing of plastic. The barrel structure of the twin-screw sixteen extruder is the same as that of the single screw extruder, and can be divided into integral barrel and segmented combination barrel. In twin-screw Extruders, integrerade fat används vanligtvis för meshing mot roterande tvillingskruv och koniska tvillingskruvextruder; Några stora extruder använder segmenterade kombinerade fat för bekvämligheten med mekanisk bearbetning .

2. Skruvstruktur:

It is the main component of the extruder. The tooth profile of the twin-screw screw in the twin-screw does not conform to the rules and cannot form a closed meshing line, belonging to the dry non sealed type. The screw is self-locking and relies on gear transmission. The master and slave screws do not directly contact each other, and the control system controls the operation and stop of Tvillingskruv Extruder .

3, matningssystem:

Baserat på egenskaperna och arbetsförhållandena för det extruderade materialet hos tvillingskruvsträngaren, antar utfodringssystemet för tvillingskruvsextruder den tvingade mätningsmetoden för att mata fatet .

Denna utfodringsutrustning är som en enda skruvextruder som arbetar vertikalt, med skruven som roterar och transporterar materialet som drivs av en likströmsmotor genom utgångsaxeln för en maskväxelreducerande . hastigheten och mängden material som transporteras av skruven bestäms av arbetshastigheten för tvillingskruvplast produkt .

4, överföringsstruktur:

Överföringssystemets funktion är att köra skruven, tillför vridmomentet och hastigheten som krävs av skruven under extruderingsprocessen, vanligtvis överförd av motorn, växellådan och lager .

The axial force generated by twin-screw during extrusion work is similar to or higher than that generated by single screw during extrusion work. Such a large axial force requires large-sized bearings to bear it. However, because the working arrangement of twin-screw limits the space for bearing arrangement to bear the axial force of the screw, there are multiple schemes for bearing arrangement.

5, uppvärmning och kylstruktur:

Heating and cooling are the fundamental conditions for the operation of plastic extruders, generally using the resistance heating barrel method. The commonly used structure is a cast aluminum resistance wire heater, which involves inserting the resistance wire into a metal tube filled with magnesium oxide insulation material, and then casting the entire tube into an aluminum alloy sleeve.
