Embodiment one
As shown in Figs 1-4, banded extruder provided in this embodiment, comprising: frame body 100 is arranged at least one on the frame body 100
A driving mechanism 200 and at least one mold 400, the driving mechanism 200 are connected with impeller 300；The mold 400 includes
Cavity 401 and extrusion 402 are stored, described 300 one end of impeller, which is extend into the storage cavity 401, pushes storage cavity
Material inside 401 is squeezed out from extrusion 402；The quantity of the driving mechanism 200 and the quantity one of the mold 400 are a pair of
It answers.Storage cavity 401 is increased, therefore increases the space of storage material, and then the material length squeezed out can be made substantially to increase
Add, solves the technical issues of squeezing out length limited.
Specifically, the aperture of the extrusion 402 is from close to the storage cavity 401 to the separate storage cavity 401
It gradually becomes smaller.That is the tapered structure of extrusion 402, when impeller 300 pushes down on, due to extrusion 402 aperture gradually
Become smaller, additionally it is possible to play the role of squeezing material, therefore it is more preferable to squeeze out effect.
Further, one end far from the storage cavity 401 on the extrusion 402 is provided with tubulose die body 403.Pipe
The setting of shape die body 403 can increase extrusion 402 to the extrusion time of material, further improve squeezing effect.
It should be noted that the height of the impeller 300 is greater than the height of the storage cavity 401.It can be to storage
The ratio that material in cavity 401 squeezes more thoroughly, avoids excessive material from remaining in the inside of storage cavity 401.
In the present embodiment optinal plan, the impeller 300 is slidably and sealingly connected with 400 inner wall of mold.Mainly
It avoids material from flowing out from the gap between 400 inner wall of impeller 300 and mold, ensure that impeller 300 and 400 inner wall of mold
Between leakproofness, be conducive to material from discharge port squeeze out.
Specifically, being provided with sealing element between 400 inner wall of the impeller 300 and the mold, 300 He of impeller is improved
The sealing performance of 400 inner wall of mold.
In the present embodiment optinal plan, the tapered structure of 402 inner wall of extrusion, and the angle that inner wall is formed is 30 °
~60 °.30 ° or 45 ° of angle is used, generally convenient for the extrusion of material.
Specifically, the height of the storage cavity 401 is greater than 800mm；In the case where storage 401 diameter of cavity is constant,
The volume for improving storage cavity 401, can store more materials, and the length for the polytetrafluoroethylene (PTFE) for allowing to squeeze out is substantially
Increase, so that the length of polytetrafluoroethylene (PTFE) can up to upper myriametre.
Further, the driving mechanism 200 includes cylinder or oil cylinder, for driving impeller 300 to move up and down.
In conjunction with can be seen that banded extruder provided in this embodiment, including frame body to the detailed description of the utility model above
100, at least one driving mechanism 200 and at least one mold 400 are set on frame body 100, driving mechanism 200 is connected with impeller
300；Mold 400 includes storage cavity 401 and extrusion 402, and 300 one end of impeller extend into storage cavity 401 and pushes storage
The material inside cavity 401 is deposited to squeeze out from extrusion 402；The quantity of driving mechanism 200 and the quantity of mold 400 correspond.
Since the quantity of driving mechanism 200 and the quantity of mold 400 correspond, i.e., mold 400 is single by corresponding driving mechanism 200
Solely control, multiple driving mechanisms 200 can be run simultaneously, can also help to improve production efficiency, and production has more with isolated operation
There is flexibility；Simultaneously because increasing storage cavity 401, therefore the space of storage material is increased, and then extrusion can be made
Material length is significantly increased；Solves the technical issues of low extrusion efficiency in the prior art and extrusion length limited.
