Description of the Related Art In the case of extruding and covering a resin on an insulator or a sheath of a cable, pellets are melted and softened in an extruder, kneaded, and then discharged from an extrusion head. Although a screw for this purpose is provided inside the extruder, it is necessary to remove the screw when cleaning the extruder or replacing the resin.

に回転し、樹脂の押出しを行うよう構成されている。FIG. 2 shows an explanatory view of a conventional method for extracting an extrusion screw. (A) shows the tool for screw extraction, (b) is sectional drawing of the extruder extraction state which used the tool. In the figure, this tool comprises a hook 1, a set screw 2 and a handle 3. (B)
As shown in FIG. 3, a screw 5 is housed in the cylinder 4 of the extruder, and is driven by a drive gear 6 to rotate in the direction of arrow 6A to extrude the resin.

方向にスクリュー５を抜き取る。When removing the screw 5 as described above, the hook 1 is hooked on the flange 4A of the cylinder 4 and a tool as shown in FIG. In this case, the push rod 7 is placed between the push screw 2 and the screw 5.
Sandwich. Then, the handle 3 is rotated in the direction shown by the arrow 8. As a result, the push screw 2 advances in the direction indicated by the arrow 9, and the push rod 7 also pushes the screw 5 in the direction indicated by the arrow 9 to pull out the screw 5 in the tip direction of the screw 5 (not shown).

In this air pump 10, when the lever 11 reciprocates in the direction of arrow 12, the piston rod 13 is pushed out in the direction of arrow 9 by the force of air. A push rod 7 is sandwiched between the piston rod 13 and the screw 5. Therefore, also in this case, the screw 5 is pushed out in the direction of the arrow 9 and pulled out in the direction of the tip thereof, as described with reference to FIG.

First, when the tool as shown in FIG. 2B is used, the tool itself has a relatively simple structure, but a large force is required to rotate the handle 3, and the burden on the operator is large. There was a problem. Further, when pulling out a long screw, the push screw 2 is reciprocated many times while replacing the push rod 7 with a longer one several times. Therefore, there is a problem that the labor for rotating the handle 3 for that purpose is very large.

ー５の抜き取りが可能になる。The extruding screw extracting device of the present invention having the above construction is used as follows. First, the threaded rod 20 having a required length is prepared in advance, and the guide 21 is penetrated from the right direction shown in FIG. Then, the drive motor 16 is rotated to rotate the feed gear 23 in the direction of arrow 24. In this way, the threaded rod 20 is fed out in the direction of the arrow 22 by the force of the feed-out gear 23, and the universal rotary joint 26 at its tip portion contacts the rear end of the screw 5. Further, when the feed gear 23 is continuously driven to rotate, the arrow 22 of the screw rod 20
The screw 5 is pushed in the same direction by the unidirectional feeding, and the screw 5 can be pulled out at the tip portion of the cylinder 4 (left side in the drawing).

If necessary, screw rods having the same structure may be connected to the rear end of the screw rod 20 and fed one after another. Also in this case,
Workability is good because there is no need to reciprocate the screw rod. Also,
Since there is the universal rotary joint 26, the extraction work may be performed while initially rotating the screw slightly.

The screw rod 20 and the guide 21 shown in the above embodiment may be combined so as to describe the movement of the screw rod 20 in the longitudinal direction with respect to the screw 5 and prevent the rotation thereof. You can fit as many grooves as you like,
The ridge may be a mere protrusion. Further, if the cross section of the threaded rod 20 is asymmetrical when viewed from its axis, the rotation of the threaded rod is prevented if the guide also has a through hole of that cross sectional shape.

Further, a universal joint is arranged at the connecting portion between the screw rod 20 and the screw 5 so that the screw 5 can freely rotate even if the screw rod 20 does not rotate. However, it is not limited to the above and may be a free and well-known configuration that allows a slip between the two.
