Definitions
- the present invention relates to a method and an apparatus for kneading and extruding a plastic resin.
- the kneading and extruding method and the kneading and extruding apparatus for a plastic resin are composed of an extruding section, an auxiliary section and their operations]).
- the extruding section includes a cylinder having a resin inlet and a screw for kneading and extruding the resin.
- the extruding section performs a kneading and extruding operation in an extrusion process zone, and performs a cleaning operation in a cleaning process.
- the accessory unit mainly includes a hopper and a drive source.
- the hopper supplies resin to the extrusion section from the resin inlet, and the drive source drives the screw with the screw.
- the basic idea of the present invention is to eliminate the interruption of the extrusion process zone by combining a plurality of extrusion parts with a single accessory part.
- An object of the present invention is to realize a kneading / extruding method and a kneading / extruding apparatus which enable a comprehensive continuous extrusion operation, eliminate the conventional disadvantages, and have a high extrusion operation efficiency. Disclosure of the invention
- An extrusion process in which a single auxiliary unit having a screw drive source and a resin supply hose is provided, a plurality of extrusion units having a resin inlet cylinder and a screw are provided, and the operation of the extrusion unit is performed by kneading and extruding the resin. And the cleaning process where the screw and cylinder are removed.
- the extruder is placed at a position where the resin inlet is always facing upward and the position can be exchanged.One of the extruders is extruded for the extrusion process.
- FIG. 2 is a side view and a cross-sectional view when there are two extrusion parts.
- 'It is a cross-sectional view when there are four extrusion parts.
- FIG. 4 is a side view when the resin inlet is directed upward
- FIG. 5 and FIG. 8 are cross-sectional views of the same case
- FIG. 7 is a side view of the same case.
- Screw drive source 18 and tree! ! Supplied with a single auxiliary unit having a supply tank ⁇ S.
- a plurality of extruded parts having a resin inlet cylinder and a screw 2 are provided.
- 3, 4, 5, &, 7 are extrusion parts.
- the push-out portion 4 and the push-out portion 5 are supported by a support arm 9 on a revolver shaft 8 and are located symmetrically with respect to the revolver shaft 8.
- the extruded portions 4, 5, 6, and 7 are in a relationship where the extruded portions 4, 5, 6, and 7 can be exchanged with each other by revolving around the lip-pole shaft 8.
- the revolver shaft 8 is revolved by the rotation mechanism 10.
- One of the plurality of extruding sections is provided as an extruding member 4 at the extruding position in the extruding step.
- the extruded parts other than the extruded body 4 are located at the cleaning position in the cleaning step, and are designated as # 5, # 6, and # 7.
- the extruding body 4 is repositioned by revolving with any of the cleaning bodies 5, 6, and 7 when is needed. The extruded part that comes to the extrusion position moves to the extrusion process.
- the extruder that comes to the cleaning position completes the cleaning process before the next revolving. Revolving can be completed in a short time.
- the position exchange may be by revolving force; or by other means, such as horizontal translation or the like.
- the method of position exchange is not limited.
- the push-out portions 3 and 4 are supported by the support arm 3 on the revolver shaft 8 and located at the position with respect to the revolver shaft 8 .o By rotating about the revolver shaft 8 as an axis, that is, revolving. By doing i? However, the extruded portions 3 and 4 are in a relationship where the positions can be exchanged with each other.
- the revolver shaft 8 is revolved by the rotary machine 1.0.
- One of the multiple extruders is located at the extrusion position in the extrusion process and is used as extrusion.
- Extrusion parts other than extrusion 3 are located at the position of the cleaning process and are designated as cleaning 114.
- the position is exchanged by the cleaning advisor 4 and the revolving.
- the ffi portion that has reached the extrusion position moves to the extrusion process.
- the sweep that arrives at the cleaning position is completed before the next revolving.
- Resin is supplied from two resin inlets. The position exchange is performed while the resin inlet 20 is always upward, but the mechanism is as follows. An example of the mechanism will be described with reference to the drawings.
- the tip of the revolver shaft 8 is supported by a fixed cylinder 21.
- One support arm 3 is fixed to a revolver shaft 8, and the other support arm 9 is not fixed to a fixed cylinder 21.
- Belt, Chini between fixed circle ⁇ 2 1 and pusher 3 3 ⁇ 4 The winding I 1 is wound S.
- the diameter of the fixed cylinder 21 at the portion where the winding band 11 is formed is equal to the diameter of the extruded portion 3.
- the projections 3 and 4 are rotatably supported by the support arm 9, respectively.
- a winding band 12 is connected between the fixed cylinder 21 and the extruded portion 4.
- the diameter of the fixed cylinder 21 at the portion where the wrapping belt 12 is in contact with the HT is equal to the diameter of the extruded portion 4.
- FIG. 5 shows the case of the extruded portions 3, 4, and 5; the operation of the wrapping band], and the resin inlet 20 always keeps upward. The same applies when the number of extruded parts is four or more.
- the 7 and 8 show another embodiment. Fix the fixed wheel 15 to the fixed cylinder 21. Extrusion portions 3 and 14 are fixed to extrusion portions 3 and 4, respectively.
- the push-out wheels 13 and 14 and the fixed wheel 15 may be, for example, friction wheels or gears. In the case of a friction wheel, the outer diameter is equal, and in the case of a gear, the pitch circle diameter is equal.
- the interlocking wheel 16 is interlocked with the extruding unit wheel 13 and the fixed wheel 15, and its shaft is supported by a support arm 9.
- the interlocking wheel 17 is connected to the extruding unit wheel 14 and the fixed wheel 15, and its shaft is supported by the arm 7.
- the resin inlet is always upwards, resin is easy to be charged and cleaned, and it is easy to attach / detach to auxiliary parts.
