JP3549244B2 - Method and apparatus for extruding a plastic resin capable of continuous extrusion cleaning - Google Patents

Description

[0001]
[Industrial applications]
The present invention relates to a method and an apparatus for extruding a plastic resin.
[0002]
[Prior art]
Continuous extrusion cleaning was almost impossible.
[0003]
[Problems to be solved by the invention]
It is an object of the present invention to provide a method and an apparatus for extruding a plastic resin capable of continuous extrusion cleaning.
[0004]
[Means for Solving the Problems]
Material charges from the inlet 1 comprises a cylinder 4 having a (product material or cleaning material) 2 is material kneaded by Sukuriyu internally supplied material 2 Sutoran de 5 a to extruding outlet 3, at the end near the product material as added continuously supplying cleaning materials for cylinder cleaning without interruption, by Rukoto to continuously supply additional product material without interruption at the end near the supply of cleaning material, extruding the materials as continuous strand如 Kusuru.
[0005]
【Example】
[0006]
This is a kneading and extruding device for plastic resin using a screw and a cylinder 4.
[0007]
The material 2 is supplied from an inlet 1, the material 2 is kneaded by a screw inside, and a cylinder 4 having an outlet 3 for extruding the material 2 as a strand 5 is provided.
[0008]
The material is the product material 2 for the pellet product and the cleaning material 6 for cleaning the cylinder 4 containing the screw. The cleaning material 6 is a plastic resin or another suitable material.
[0009]
In the vicinity of the end of the supply of the product material 2 (shown in FIG. 2), the cleaning material 6 is continuously and continuously supplied without interruption (shown in FIG. 2).
[0010]
Near the end of the supply of the cleaning material 6, the product material 2 is continuously and continuously supplied without interruption (shown in FIG. 3).
[0011]
Repeat this operation.
[0012]
The method and apparatus for continuous additional continuous supply are not limited.
[0013]
When the hopper 7 that supplies the material 2 becomes empty, the next material may be charged into the hopper 7.
[0014]
Alternatively, it may be mounted on another new hopper 8, and the next material may be charged.
[0015]
The vicinity of the end of the supply can be detected by a level sensor or the like, and the next material can be automatically supplied. This is only a problem of automation of continuous additional supply.
[0016]
【The invention's effect】
The strand 5 is turned into a cooling strand 9 by a cooling device, and the pellet 10 cut by the cutter is stored in a pellet receiver 11.
[0017]
The present invention has the following effects.
[0018]
The strand 5 and the cooling strand 9 are not interrupted on the way.
[0019]
Therefore, since the man-hour for re-guiding the strand 5 during the work can be omitted, the efficiency of the extrusion work is improved.
[0020]
For example, the product pellets are stored in the pellet receiver 11, and the cleaning pellets are stored in the pellet receiver 12. The storage of the pellet receivers 11 and 12 can be appropriately linked to the automation of continuous additional continuous supply. The interlocking mechanism is merely a means such as a mechanical design, and is not limited.
[0021]
Since the cleaning process is simplified, the overall work efficiency is improved.
