Description
Technical field
Marble screw rod is the utility model is related to, belongs to screw technique field.
Background technology
Screw rod is the core component of plastic molding equipment, is the part for heating extrusion plasticizing, is the core of plastic machine.Mesh
Processing parian raw material, the screw head knot of prior art screw rod are all used as using extrusion machining pvc materials as previous
Structure is all fairly simple so that pvc products easily mix bubble during discharging, and screw head does not have the work(for removing bubble
Can, easily there is bubble in the product of output.In order to solve above-mentioned difficulties, it is necessary to which developing a needs to develop a screw head energy
Remove the marble screw rod of bubble.
The content of the invention
The purpose of this utility model is to provide marble screw rod.
Problem to be solved in the utility model is that the screw head of the prior art is simple in structure, without the work(for removing bubble
The problem of energy.
To realize the purpose of this utility model, the technical solution adopted in the utility model is：
Marble screw rod, including screw head circle, screw head, the first screw body, the second screw body, the 3rd screw body, incline, company
Section, the 4th screw body and spiral shell rib are connect, screw head circle is installed at the top of the screw head, screw head circle there are three cylinders to form, two circles
Cylinder is located on screw head, another cylinder is positioned at the top of two cylinders, and screw head is located above the first screw body, spiral shell
Head and the first screw body are integrated connection, and the first screw body is located above the second screw body, the first screw body and the second screw rod
Body is integrated connection, and the second screw body is located above the 3rd screw body, and the second screw body and the 3rd screw body are integrated connection, the
Three screw body surroundings respectively install linkage section, the side installation incline of linkage section, and the 3rd screw body is located above the 4th screw body, the
Four screw bodies and the 3rd screw body are integrated connection, and the 4th screw body is externally provided with is equipped with spiral shell rib from top to bottom.
The cylinder of the screw head circle is hollow cylindrical structure.
The utility model has the advantages that：Spiral shell rib outside 4th screw rod becomes larger from top to bottom, and the spiral shell rib of this structure makes
Pvc materials be kneaded more fully, and material is elapsed forward rapider for spiral shell rib；Incline can make mixing process adequacy,
More preferably, product quality is high, does not have bubble for even property；First screw body diameter is more than screw head diameter structure so that discharging is more
Rapidly, screw head circle can play the role of material friction and promote, the bubble in material is discharged, screw head circle during discharging
Have the function of to remove in bubble.
Brief description of the drawings
Fig. 1 is the utility model marble screw rod overall structure figure；
Fig. 2 is the three-dimensional structure diagram of spiral shell rib；
Fig. 3 is the top view of screw head circle；
Fig. 4 is the top view of incline；
In figure：1st, screw head circle 2, screw head 3, the first screw body 4, the second screw body 5, the 3rd screw body 6, incline
7th, linkage section 8, the 4th screw body 9, spiral shell rib.
Embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
The utility model marble screw rod, including screw head circle 1, screw head 2, the first screw body 3, the second screw body the 4, the 3rd
Screw body 5, incline 6, linkage section 7, the 4th screw body 8 and spiral shell rib 9, the top of the screw head 2 installation screw head circle 1, screw head circle 1 has
Three cylinders are formed, and two cylinders are located on screw head 2, and 3 diameter of the first screw body is more than 2 diameter structure of screw head, makes
It must discharge more rapid, screw head circle 1 can play the role of material friction and promote, by the bubble in material during discharging
Discharge, screw head circle 1 have the function of that bubble is removed another cylinder is located at positioned at the top of two cylinders, screw head 2
The top of first screw body 3,2 and first screw body 3 of screw head are integrated connection, and the first screw body 3 is located in the second screw body 4
Side, the first screw body 3 and the second screw body 4 are integrated connection, and the second screw body 4 is located at the top of the 3rd screw body 5, the second screw rod
4 and the 3rd screw body 5 of body is integrated connection, and 5 surrounding of the 3rd screw body respectively installs linkage section 7, the side installation incline of linkage section 7
6, incline 6 can make mixing process adequacy, uniformity more preferably, and product quality is high, does not have bubble；3rd screw body 5 is positioned at the
The top of four screw body 8, the 4th screw body 8 and the 3rd screw body 5 are integrated connection, and the 4th screw body 8 is externally provided with to be set from top to bottom
There is a spiral shell rib 9, the spiral shell rib 9 outside the 4th screw rod becomes larger from top to bottom, and the spiral shell rib 9 of this structure makes pvc materials be kneaded more
Fully, and spiral shell rib 9 material is elapsed forward rapider；The cylinder of screw head circle 1 is hollow cylindrical structure.
The utility model application method：Spiral shell rib 9 outside 4th screw rod becomes larger from top to bottom, the spiral shell rib 9 of this structure
Make that pvc materials are kneaded more fully, and material is elapsed forward rapider for spiral shell rib 9；Incline 6 can make mixing process abundant
Property, uniformity more preferably, product quality is high, does not have bubble；First screw body, 3 diameter is more than 2 diameter structure of screw head so that goes out
Material is rapider, and screw head circle 1 can play the role of material friction and promote, the bubble in material is discharged during discharging,
Screw head circle 1 has the function of to remove in bubble.
