Abstract
The utility model discloses a novel screw extruder. The novel screw extruder comprises a feeding opening, a screw, a sleeve, a discharging opening and a motor, wherein the screw is divided into three sections; a first section is a feeding and conveying section; a tapered spiral thread is arranged on the feeding and conveying section of the screw; the second section is a mixing section; the depth of the thread on the mixing section of the screw gradually shallows till zero; a screw edge is interrupted for three times; the third section is an extruding and glue discharging section; a tapered spiral thread is arranged on the extruding and glue discharging section of the screw; a groove is formed in the inner wall of the sleeve; the plasticization pressure in the whole sleeve becomes greater, so that the shearing is more severe, thus the plasticization effect is more obvious; the novel screw extruder is especially suitable for plasticizing and pelleting of a high filling system and high-molecular-weight resin.
Description
Technical field
The utility model relates to a kind of screw extruder structure.
Background technology
Screw extruder is mainly used in plastic extrusion processing, the screw flight of existing screw extruder is generally identical, material medicament easily pile up and mix inhomogeneous, especially some full-bodied materials, common screw rod cannot reach needed technical requirement.
Summary of the invention
The utility model provides a kind of new type screw extruder in order to solve deficiency of the prior art, and convey materials speed is variable, material in sleeve continuous discharge, avoid a large amount of solid accumulations, good mixing effect.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of new type screw extruder, comprise charging aperture, screw rod, sleeve, discharging opening, motor, described screw rod is divided into three sections, first paragraph is reinforced span line, on reinforced span line screw rod, be the screw with tapering, second segment is mixing section, and the degree of depth of the screw thread on mixing section screw rod is by shoaling deeply gradually, until be zero, spiral shell rib interrupts three times; The 3rd section is extrusion binder removal section, and extruding on binder removal section screw rod is the screw with tapering; On described sleeve lining, offer groove, it is large that plasticizing pressure in whole sleeve becomes, and shears more violently, and plasticizing effect is more obvious, is specially adapted to the plasticizing granulation of high infill system and high molecular weight resin.
As a kind of preferred version of the novel described new type screw extruder of this use, on described mixing section sleeve lining, be distributed with pin, increase shear stress on the one hand, strengthened plasticizing effect, prevented that on the other hand a large amount of materials from adhering to, piling up on sleeve lining.
Beneficial effect:
New type screw extruder described in the utility model, by the screw thread on screw rod having been done to a series of variation and having increased the groove on sleeve lining, has greatly reduced the accumulation of material, has strengthened plasticizing effect; By pin feature, more strengthen the plasticizing effect of extruder, greatly improve quality and the productivity ratio of product.
Brief description of the drawings
Fig. 1 is new type screw extruder structural representation described in the utility model.
Wherein: 1, charging aperture 2, screw rod 3, sleeve 4, discharging opening 5, motor 21, reinforced span line 22, mixing section 31, groove 32, pin
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
As shown in the figure, a kind of new type screw extruder, comprise charging aperture 1, screw rod 2, sleeve 3, discharging opening 4, motor 5, described screw rod is divided into three sections, and first paragraph is reinforced span line 21, the screw rod of reinforced span line is the screw with tapering, second segment is mixing section, and the degree of depth of the screw thread on mixing section screw rod is by shoaling deeply gradually, until be zero, spiral shell rib interrupts three times, is distributed with pin 32 on the sleeve lining of mixing section; The 3rd section is extrusion binder removal section 23, and extruding binder removal section screw rod is the screw with tapering; On described sleeve 3 inwalls, offer groove 31, coordinate with screw thread on screw rod is staggered.
Although embodiment of the present utility model is illustrated in description, these embodiments just, as prompting, should not limit protection domain of the present utility model.In the scope that does not depart from the utility model aim, carrying out various omissions, displacement and change all should be included in protection domain of the present utility model.
Claims (2)
1. a new type screw extruder, comprise charging aperture, screw rod, sleeve, discharging opening, motor, it is characterized in that: described screw rod is divided into three sections, first paragraph is reinforced span line, on reinforced span line screw rod, be the screw with tapering, second segment is mixing section, and the degree of depth of the screw thread on mixing section screw rod is by shoaling deeply gradually, until be zero, spiral shell rib interrupts three times; The 3rd section is extrusion binder removal section, and extruding on binder removal section screw rod is the screw with tapering; On described sleeve lining, offer groove.
