- a cutter that rotates on the extrusion surface of the die device 100.
- an underwater cut method in which the extrusion surface of the die apparatus 100 is covered with water and cut while being cooled may be used, or a hot cut method in which cutting is performed without performing special cooling may be used.
- the first extruder 400 and the first extruder 400 are connected to the core material supply port 311 and the second extruder 500 is connected to the sheath material supply port 321.
- the first die apparatus main body 250 and the second die apparatus main body 200 are mutually rotated and connected, and the core material supply port 311 is connected to the second extruder.
- the sheath material supply port 321 By connecting the sheath material supply port 321 to the first extruder 400, the first extruder 400 and the second extruder 500 can be exchanged without changing the direction on the installation plane. It becomes possible to do.
- the first extruder 400 and the second extruder 500 that are connected before being rotated are defined as The position in the height direction is shifted.
- the positional deviation in the height direction is absorbed by a height adjusting device as shown below. This height adjusting device will be described below.
- Fig. 6 is a perspective view showing a case where the first extruder and the second extruder each include a lifting device as height adjusting devices
- Fig. 7 (a) is a diagram in Fig. 6 (a).
- (B) is a Vllb-VIIb arrow view in Fig. 6 (b).
- the first extruder 400 and the second extruder 500 are each provided with a lifting device. If the first die unit body 250 is rotated 90 ° clockwise and the second die unit main body 200 is rotated 90 ° counterclockwise, the first extruder 400 is raised. The second extruder 500 is configured to raise the height H, and then the second extruder 500 is raised.
- a device that moves up and down by rotation of a ball screw 520 protruding upward from the table 510 can be used.
- a hydraulic cylinder may be used in place of the ball screw 520.
- the extruder may be raised using a jack or the like, and a spacer or the like may be attached to the gap to maintain the height.
- the first extruder 400 and the second extruder 500 are moved up and down without changing the height of the die device 100.
- the height of the second extruder 500 and the die unit 100 may be changed without changing the height of the extruder 400.
- FIG. 8 shows a case where the second extruder includes a lifting device as a height adjusting device
- (a) and (b) are diagrams corresponding to FIGS. 7 (a) and (b), respectively.
- the second extruder 500 is lowered by 2H and the die unit 100 is lowered by H, so that the first extruder 400 remains stationary and the position in the height direction is shifted. Can be absorbed.
- the lifting device also increases in size. Since the first extruder 400 remains stationary, a large lifting device that can lift and lower the first extruder 400 becomes unnecessary.
- a suspension bolt having a ring portion at the upper end is attached to the upper surface of the die device 100, and a leading end of a wire, a chain, or the like is locked thereto. And lift it with a winch.
- FIG. 9 is a perspective view showing a case where a curved connecting pipe is provided as a height adjusting device
- FIG. 10 (a) is a view taken along the arrow Xa—Xa in FIG. 9 (a).
- b) is the Xb—Xb arrow in Fig. 9 (b).
- FIG. As shown in FIGS. 9 and 10, the die apparatus 100, the first extruder 400, and the second extruder 500 are all connected pipes having different heights at one end and the other without changing the height. By connecting 316 and 326 between them, the positional deviation in the height direction may be absorbed.
- connection pipes 316, 326 In order to avoid the connection pipes 316, 326 from being bent sharply, a sufficient distance L between the die device 100 and the first extruder 400 and the second extruder 500 is secured. It is necessary to keep it. Therefore, even when there is no position shift in the height direction, long connecting pipes 315 and 325 are used as shown in FIGS. 9 (a) and 10 (a).
- connection pipes 316 and 326 By using such connection pipes 316 and 326, the positional deviation in the height direction in which the die device 100, the first extruder 400, and the second extruder 500 are all moved up and down is absorbed. It can be done.
- the extruder and sheath material for extruding the core material without changing the direction of the first extruder 400 and the second extruder 500 Can be replaced with an extruder that extrudes.
- the productivity of the multilayer strand 900 with the core-sheath ratio reversed is improved.
- the materials are exchanged while leaving the materials inside the first extruder 400 and the second extruder 500. As a result, it is possible to save the trouble of replacing or cleaning the material inside the extruder 500.
- the core nozzle 270 and the bolt 290 are two, four, and six at regular intervals, respectively. Realize a structure that can be rotated 180 ° by installing multiples of 2, as required, such as 8, 10 can do.
- the nozzle 270 for the core and the bolt 290 are arranged.
- a structure capable of rotating 120 ° can be realized by providing multiples of 3 as required, such as three, six, nine, and twelve nozzle nozzles 270 and bolts 290 at equal intervals. .
- the die device is used for the manufacture of a multilayer extrusion product having a core-sheath structure in which a sheath material is coated on the outer periphery of the core material.
- a die-sheath device having a core-sheath structure can be manufactured.
