Abstract
The utility model provides a material conveying structure for an extruder, and the material conveying structure comprises a machine barrel, a charging hopper and a screw rod, wherein the screw rod is in the form of a two-section structure, one section is composed of cylindrical screw rods, and the other section is composed of conical screw rods; the cylindrical screw rods are arranged in the measuring section and the compressing section of the screw rod, and the conical screw rods are distributed in the charging section; and the machine barrel is cylindrical in the measuring section and the compressing section, and is conical in the charging section. The machine barrel is of a sectioned-type structure, and comprises a measuring-compressing section and a charging section. The charging hopper is connected to the machine barrel, and a material guiding mechanism is arranged on the charging hopper. The screw rod structure is different in structural form in each section, and by virtue of the design of the conical screw rod of the screw rod structure, the speed of conveying materials can be increased, and the occurrence of a blockage problem of the materials in the machine barrel can be reduced, i.e., the occurrence of an uncontrollable pressure is reduced; and therefore, a guarantee is provided for quality control in the next step.
Description
Technical field
The utility model relates to a kind of extruder conveying 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 conveying structure, this screw-rod structure is different in the version of each section, the design of its conical screw, can strengthen the speed of convey materials, reduce the generation of material blockage problem in machine barrel, also just reduced the generation of uncontrollable pressure, therefore, for the control of next step quality provides assurance.
For solving above technical problem, the technical scheme that the utility model provides is as follows: a kind of that extruder conveying structure, and described screw rod is divided into the two-stage structure form, and one section is the cylindricality screw rod, and one section is conical screw; The cylindricality screw rod is arranged in metering section and the compression section of screw rod, and conical screw is distributed in feeding section; Be connected with feed hopper on the described machine barrel, be provided with on the feed hopper and draw material mechanism.
Further, described machine barrel is cylindricality in metering and compression section, is taper at feeding section.
Further, described machine barrel is segmentation structure, and metering and compression section are one section, and feeding section is one section.
Further, the described material mechanism of drawing comprises motor and agitator, and described motor is fixed on the motor rack that connects machine barrel, and described agitator connects motor output shaft.
Further, described agitator is a screw rod or a band-shaped plate, by the rotation of agitator material is introduced in the machine barrel.
This extruder conveying structure that the utility model relates to 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 the utility model extruder conveying structural representation;
The 1-tapered cylinder; The 2-conical screw; The 3-feed hopper; 4-cylindricality machine barrel; 5-cylindricality screw rod; The 6-agitator; The 7-motor.
The specific embodiment
As shown in Figure 1, screw rod is divided into the two-stage structure form, and one section is that 5, one sections of cylindricality screw rods are conical screw 2; Cylindricality screw rod 5 is arranged in metering section and the compression section of screw rod, and conical screw 2 is distributed in feeding section.
Corresponding machine barrel also is divided into cylindricality machine barrel 4 and tapered cylinder 1.
The material mechanism of drawing on the feed hopper 3 comprises motor 7 and agitator 6, and described motor 7 is fixed on the motor rack that connects machine barrel, and agitator 6 connects motor output shaft.
Agitator 6 is a screw rod or a band-shaped plate, by the rotation of agitator 6 material is introduced in the machine barrel.
This extruder conveying structure that the utility model provides, 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.
