Abstract
The utility model provides an extruding structure of an extruder. The extruding structure comprises a machine cylinder and a screw rod, wherein the screw rod is structurally divided into six areas, namely, a first feeding area, a smelting mixing area, a second feeding area, a mixing area, a gas discharge area and a pressurizing area; the feeding area is arranged on the machine cylinder and is provided with a feeding port; the gas discharge area is arranged on the machine cylinder and is provided with a gas discharge port; the machine cylinder is divided into seven equal sections; the smelting mixing area occupies two sections; the other areas respectively occupy one section; the screw rod is in a sectional structure; the sections are connected in a bonding mode or a welding or threaded connection mode; and forward rotation direction screw teeth are arranged on the screw rod at the feeding area. The screw rod structure is in different structural modes at the different sections, and the two feeding areas and the gas discharge area are provided, so that the structure can effectively control the pressure in the material conveying process, the possibility that materials are blocked in the machine cylinder is reduced, and meanwhile, the possibility of uncontrollable pressure is reduced, so that the next quality control is ensured.
Description
Technical field
The utility model relates to a kind of extruder and extrudes structure,
Technical background
Injection screw is by its adaptability to plastics, can be divided into Universal screw rod and special screw rod, Universal screw rod claims again conventional screw, can process major part and have thermoplastic low, middle viscosity, civilian plastics and the engineering plastics of crystal type and non-crystalline type, be the most basic form of screw rod, its corresponding also have special screw rod, is processing with the unmanageable plastics of common screw; Press screw-rod structure and geometric characteristic thereof, can be divided into conventional screw and new screw, conventional screw is called again three-stage screw, is the citation form of screw rod, the new screw form then has a variety of, such as separating screw rod, bypass type screw rod, wavy screw rod, without metering section screw rod etc.Its screw thread effective length of conventional screw is divided into feeding section (transportation section), compression section (fluxing zone), metering section (homogenizing zone) usually.
The utility model content
The utility model provides a kind of extruder to extrude structure, this screw-rod structure is different in the version of each section, and be provided with two charging zones and an exhaust area, in the logistics course of conveying, this structure is controlled pressure effectively, reduces the generation of material blockage problem in machine barrel, has reduced simultaneously the generation of uncontrollable pressure, therefore, the control for next step quality provides assurance.
For solving above technical problem, the technical scheme that the utility model provides is as follows: a kind of extruder is extruded structure, comprise machine barrel and screw rod, described screw-rod structure is divided into six districts: the first charging zone, melting mixing district, the second charging zone, mixed zone, exhaust area and anallobar, charging zone is provided with on machine barrel, and being provided with charge door, exhaust area is provided with exhaust outlet at machine barrel; Seven sections of described machine barrel five equilibriums, the melting mixing district occupies two sections, and other each districts respectively account for one section; Screw rod is segmentation structure, the connected mode that adopts key to connect or weld or be threaded between every section.
Further, the screw rod of described charging zone has positive rotation direction spiral shell tooth.
Further, the screw rod of described melting mixing district and mixed zone has positive rotation direction spiral shell tooth, rectangle spiral shell tooth and derotation to the spiral shell tooth.
Further, the concrete structure of described rectangle spiral shell tooth is: have three ellipsoids on the screw rod, rectangle spiral shell tooth is arranged on the major axis place or is an inclination angle with major axis.
Further, the screw rod of described anallobar and exhaust area has positive rotation direction spiral shell tooth.
This extruder that the utility model relates to is extruded structure, is Split type structure, and the version of every segment structure is different, is applicable to the different requirements of each section of extrusion process, Improving The Quality of Products.
Description of drawings
Fig. 1 is that the utility model extruder is extruded the structural entity structural representation;
The positive rotation direction spiral shell of 1-tooth; 2-rectangle spiral shell tooth; The 3-derotation is to the spiral shell tooth; The positive rotation direction spiral shell of 4-tooth; 5-rectangle spiral shell tooth; The positive rotation direction spiral shell of 6-tooth; 7-the first charge door; 8-the second charge door; The 9-exhaust outlet.
The specific embodiment
As shown in Figure 1, extruder is extruded structure and is comprised machine barrel and screw rod, described screw-rod structure is divided into six districts: the first charging zone, melting mixing district, the second charging zone, mixed zone, exhaust area and anallobar, charging zone is provided with at machine barrel and is provided with the first charge door 7 and the second charge door 8, and exhaust area is provided with exhaust outlet 9 at machine barrel; Seven sections of described machine barrel five equilibriums, the melting mixing district occupies two sections, and other each districts respectively account for one section; Screw rod is segmentation structure, the connected mode that adopts key to connect or weld or be threaded between every section.
The screw rod of the first charging zone has positive rotation direction spiral shell tooth 1, the second charging zone and has positive rotation direction spiral shell tooth 5.
Melting mixing district screw rod has positive rotation direction spiral shell tooth 1, rectangle spiral shell tooth 2 and derotation to spiral shell tooth 3, and wherein rectangle spiral shell tooth 2 and derotation as shown in the figure, are a segmentation of screw rod to spiral shell tooth 3, and this spiral shell toothing can be used as one section and carries out machining.The screw-rod structure of mixed zone is similar to the screw-rod structure in melting mixing district.
The concrete structure of rectangle spiral shell tooth is: have three ellipsoids on the screw rod, rectangle spiral shell tooth 2 and rectangle spiral shell tooth 5 are arranged on the major axis place or are an inclination angle with major axis.
The screw rod of anallobar and exhaust area has positive rotation direction spiral shell tooth 6.
This extruder that the utility model provides is extruded structure, and version is simple, makes simple, easy for installation.
The specific embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
