Abstract
The utility model discloses a kind of screw rods and extruder for extruder, screw rod wherein for extruder is divided into stirring for positive single thread slot according to thread surface rotation direction difference and section, reversed single thread slot or the spacer of annular groove and the back-pressure section of incorgruous double thread slot, the thread groove of the back-pressure section end is pressed to be connected with screw rod end face.The utility model squeezing effect is good, can be good at the extrusion forming suitable for flexible material, is not in not discharge or fracture.
Description
Technical field
The utility model is related to a kind of screw rods and extruder for extruder.
Background technology
In new-energy automobile, the technology of electric vehicle is the most ripe, and country builds the facilities such as charging pile energetically now,
Middle electric vehicle charging gun and the cable of its connection are essential, and the wire body of cable is different from general wire body, need to meet Gao Rou
Soft and wearability, insulating materials are mostly calcium zinc mild alloy, and because of its special formula technique, existing classic screw squeezes signature
The screw rod of machine be mostly single thread can not good extrusion forming, easily cause fracture or do not discharge, make the physical property of the outer quilt of cable
It is unable to reach the requirement of charging gun cable.
Utility model content
The utility model proposes a kind of spiral shell for extruder to solve above-mentioned technical problem in the prior art
Bar and extruder.
The technical solution adopted in the utility model is：
A kind of screw rod for extruder, the screw rod are divided into positive single thread slot according to thread surface rotation direction difference
Stir pressure section, reversed single thread slot or the spacer of annular groove and the back-pressure section of incorgruous double thread slot, the back-pressure section end
Thread groove is connected with screw rod end face.
The corresponding screw compression ratio of pressure section that stirs is 1:1.5 to 1:1.7.
A kind of extruder, including motor, one end connection motor can along axial line rotate screw rod, set loading screw rest part
Spiral shell cylinder, the screw rod according to thread surface rotation direction difference be divided into positive single thread slot stir pressure section, reversed single thread slot
Or the spacer of annular groove and the back-pressure section of incorgruous double thread slot, the thread groove of the back-pressure section end are connected with screw rod end face；
The corresponding spiral shell casing wall of pressure section initial thread slot notch that stirs is equipped with feed inlet, the back-pressure section thread groove connection
Screw rod the other end face correspond to spiral shell cylinder end face equipped with discharge port, between the screw rod and discharge port between be separated with back-pressure area.
The passage of the discharge port is in round table-like.
Compared with the prior art, the utility model has the advantage of：
It is more preferable to stir pressure effect, material is enable fully to stir pressure, uniformly mixes and rubs, is pressed into well suitable for stirring for flexible material
Type is not in not discharge or fracture, can reach the highly-flexible of the outer quilt of charging gun cable and wear-resisting performance.
Description of the drawings
Fig. 1 is the floor map of the utility model screw rod；
Fig. 2 is the planar structure schematic diagram of the utility model extruder.
Specific embodiment
Below in conjunction with the accompanying drawings and the principle and structure of the utility model is described in detail in embodiment.
As shown in Figure 1, the utility model proposes a kind of screw rods for extruder, the screw thread on 1 surface of screw rod is according to spiral shell
Groove rotation direction difference screw rod is divided into be arranged in order stir pressure section 11, spacer 12 and back-pressure section 13.Screw rod is close to the one of end
Section carries stirring for positive single thread slot for surface and presses section 11, wherein stirring the screw compression ratio of pressure section 11 1:1.5 to 1：1.7 it
Between；Followed by spacer 12, the thread groove of spacer is reversed single thread slot, makes to be stirred in pressure material conveyance to occur being detained to subtract
Speed is finally the back-pressure section 13 of surface while the incorgruous double thread slot equipped with reverse thread slot and forward screw thread slot, material is made to exist
It there is also the power of reverse reflux while conveyance, that improves material stirs pressure degree, back-pressure section end and screw rod the other end face
It is connected, makes the transport force of screw rod end will not interrupt, improves the service efficiency of screw rod.
As shown in Fig. 2, the utility model also proposed a kind of extruder using upper screw rod, rotated including providing screw rod 1
The motor 3 of power, one end of screw rod 1 are connected with motor 3, make motor 3 that screw rod 1 can be driven to rotate vertically, its remaining part of screw rod
It point is sleeved in spiral shell cylinder 2, spiral shell cylinder is cylindrical in shape, the rotation in spiral shell cylinder 2 of screw rod 1, and screw rod 1 penetrates one end of spiral shell cylinder 2 and does at sealing
Reason prevents that material is revealed when extruder from working.Wherein, the pressure section 11 of stirring on screw rod is corresponded to above the inner wall of spiral shell cylinder equipped with feed inlet
21, for launching the material for being stirred pressure, corresponding 2 endface of spiral shell cylinder of the other end of screw rod 1 is equipped with discharge port 22, discharge port 22
Passage is overlapped in round table-like axis with the axis of screw rod.The bottom surface of discharge port 22 forms circular hole, the bottom of round platform in the end face of spiral shell cylinder 2
Face area is more than top surface area, and top surface is outwardly, forms passage.Round table-like 22 passage of discharge port ensures material table during discharging
The flatness in face concentrates the pressure of discharge port and mitigates discharge outlet counter-pressure.It is separated between spiral shell cylinder end face and the end of screw rod
A distance, the spiral shell cylinder inner cavity of this segment distance is back-pressure area 23, and back-pressure area 23 further increases the extruding of material, improves extruder
Efficiency.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
