Description
Technical field
Patent of the present invention be related to it is a kind of can by a small amount of polymer heat melting extrusion into silk extrusion device, more particularly to
A kind of novel simple screw-type extruder.
Background technology
In macromolecule advanced material research field, when doing performance evaluation experiment to some polymer, it is often necessary to will be poly-
Compound is extruded into silk, and a kind of polymer of structure is devised sometimes, difficult due to synthesizing with high costs, building-up process, finally gathers
The yield of compound only has several grams even less, and is done for a small amount of polymer product after infrared and nuclear-magnetism sign, is processed
It is molded and then tests its physical property difficulties, because the device for processing a small amount of polymer on the market at present is less, and these
Apparatus structure is complicated, expensive.The present invention proposes a kind of novel simple screw-type extruder, and it can will be a small amount of
Polymer（2g or so）It is extruded into silk, it is possible to the polymer fiber of different thicknesses is obtained by changing jet orifice diameter.
The content of the invention
The present invention solves the technical problem of providing a kind of screw extruder of novel simple, it can will be a small amount of
Polymer（2g or so）It is extruded into silk, it is possible to the polymer fiber of different thicknesses is obtained by changing jet orifice diameter.
In order to solve the above technical problems, a kind of technical scheme that the present invention is used is：A kind of novel simple screw extrusion
Machine, including handle, screw rod, piston, fixed blocks, barrel, nozzle connection, heating mantle, brass nozzle composition；It is characterized in that：
The centre of handle is provided with a thread groove, and the upper end of screw rod is threaded into groove, and lower end and the piston of screw rod are fixed, and piston is inserted into
Fixed blocks, fixed blocks lower end is designed with internal thread, and barrel upper end is designed with external screw thread, and barrel is directly threaded into fixed blocks
In, while barrel can be just stuck in the square groove of fixed plate through the circle in the middle of fixed plate, fixed blocks, nozzle connection is fixed on
Around a circle heating mantle outside barrel lower end, barrel, brass nozzle is screwed on nozzle.
Further, there is one end pyramid type structure at the top of the piston, the promotion of piston is rotated by screw spiral.
Further, described fixed blocks are shaped as square, middle two kinds of internal threads for having the different pitch of diameter the same.
The advantage of patent of the present invention is：A small amount of polymer can be extruded into silk, and the silk extruded is than more uniform, dress
Put easy to clean, easy to use, low manufacture cost itself.

Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention are more
It is easy to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Fig. 1-5 are referred to, the embodiment of the present invention includes：A kind of novel simple screw-type extruder, including handle（1）, spiral shell
Bar（2）, piston（3）, fixed blocks（4）, barrel（5）, nozzle connection（6）, heating mantle（7）, brass nozzle（8）Composition；It is special
Levy and be：Handle（1）Centre be provided with a thread groove, screw rod（2）Upper end be threaded into groove, screw rod（2）Lower end and work
Plug（3）It is fixed, piston（3）It is inserted into fixed blocks（4）, fixed blocks（4）Lower end is designed with internal thread, barrel（5）Upper end is set
In respect of external screw thread, barrel（5）It is directly threaded into fixed blocks（4）In, nozzle connection（6）It is fixed on barrel（5）Lower end, barrel
（5）Outside is around a circle heating mantle（7）, brass nozzle（8）It is screwed into nozzle connection（6）On, barrel passes through fixed plate（9）It is middle
Circle, fixed blocks are just stuck in fixed plate（9）Square groove in.Cooperation on barrel between fixed nozzle and brass nozzle, makes
Be 3D printer accessory as spinning nozzle, by the brass nozzle of hyperphoric different pore size, different-diameter can be obtained
Polymer spun fibers.
Piston of the present invention（3）Top have one end pyramid type structure, the promotion of piston is rotated by screw spiral.
Fixed blocks of the present invention（4）It is shaped as square, middle two kinds of internal threads for there are the different pitch of diameter the same.
The present invention operation principle be：Main body is made up of piston and barrel, and the mismatch error between piston and barrel is
0.06mm（Prevent stripped thread from influenceing the extraction of piston, while also ensure that the tight fit between piston and barrel）；Piston upper
Screw rod is connected with, screw rod is screwed in into the fixed blocks with screw when using, inserted the piston into barrel, the insertion of the screw rod other end
A heating mantle is added in screwed handle, outside barrel as heater and temperature regulating device control temperature is connected；Use
When polymer is milled into powder, be added in barrel, be heated to more than corresponding melt temperature according to polymer different melting points,
Screw rod is at the uniform velocity screwed with handle again, realizes that polymer is uniformly extruded into silk from nozzle.
The present invention job step be：Brass nozzle is first loaded onto, then polymer is milled into powder and is added in barrel, it is living
Plug is inserted into barrel, tightens fixed blocks, then barrel is fixed in a fixed plate, and fixed blocks are stuck in into fixed plate
On, then by heating mantle heats temperature to polymer melting temperature more than, insulation ten minutes after, uniformly screw handle with hand, gather
Compound can be extruded into silk from brass nozzle.Extrude after job done, piston is up revolved while hot, fixation side is then turned on
Block, piston is extracted out from barrel.
