Abstract

PURPOSE:To ensure stable extrusion function, even if the hardness and thickness of a material change. CONSTITUTION:A supply orifice 3 for supplying a material is provided at the base end of a cylinder 1. In addition, a screw 2 which allows the bite of a material and its transport to the tip of the cylinder 1, is provided in the cylinder 1. Further, the screw 2 is composed of a rotary shaft 6 and a spiral blade 7. At a part located in the supply orifice 3, the spiral blade 7 has the same circumferential diameter and the rotary shaft 6 has a circumferential diameter which becomes gradually narrower toward the tip. Under this constitution, if a material which allows an easy bite of itself is introduced from the supply orifice 3 in the base and side of the cylinder 1, the bite of the material is restricted as an interval between the cylinder 1 and the rotary shaft 6 is narrow. On the contrary, if a material which does not allow an easy bite of itself is introduced from the supply orifice 3 on the tip side of the cylinder 1, the bite of the material becomes deeper as the interval between the cylinder 1 and the rotary shaft 6 is wide. Consequently, both materials are always allowed to have a stable bite.

Is provided. The tape-shaped rubber material cut into pieces is supplied from the supply port 21 to the cylinder 20.
It is continuously introduced in. A screw 24 including a spiral blade 22 and a rotary shaft 23 is provided in the cylinder 20. By the rotation of the screw 24, the rubber material is bitten into the cylinder 20 and sheared,
It is transferred to the tip end side of the cylinder 20 (left part in FIG. 3). A heater (not shown) is provided on the outer periphery of the cylinder 20, and the sheared rubber material is melted by the heat generated by the heater and is extruded from the discharge port 25 and discharged.

That is, when the rubber material easily bites, the rubber material once bited into the cylinder 20 may flow back to the supply port 21 and accumulate in the supply port 21 as a large amount of banks. In this case, the bank is again screw 2
As a result, the amount of the rubber material discharged from the discharge port 25 becomes unstable by being bitten into the cylinder 20.

The amount of the rubber material discharged from the discharge port 25 decreases, and the discharge flow of the rubber material becomes unstable. In this case, in the conventional extruder, since the supply port 21 is simply wedge-shaped, the supply port 21 is formed depending on the hardness and thickness of the rubber material.
It is necessary to adjust the depth and width of the. Specifically, it is necessary to correct the shape of the supply port 21 or replace the cylinder 20 with the supply port 21 having a different shape, which is very complicated.

A screw that is provided and transfers the rubber material supplied from the supply port to the tip portion of the cylinder by its rotation, and is provided at the tip portion of the cylinder,
An extruder having a discharge port for discharging a rubber material transferred by the screw, wherein a portion of the screw located at the supply port has a mountain diameter of approximately the same in any part, The gist is to reduce the root diameter toward the tip side.

In the invention described in (1), the rubber material is introduced into the cylinder from the supply port, is bitten by the rotation of the screw and is sheared, and is conveyed to the tip along the cylinder, and the rubber material is discharged from the discharge port.

が安定して押出される。At this time, the rubber material which easily bites is continuously introduced into the supply port on the base end side of the cylinder. With this supply, even if it is a rubber material that easily bites, the root diameter of the screw expands toward the base end side, so the gap between the screw and the inner surface of the cylinder becomes smaller, and it becomes difficult to bite. . Then, due to the large amount of bite, the rubber material once bite into the cylinder does not flow back to the supply port. That is, a stable bite amount is always ensured by suppressing the bite amount of the rubber material that easily bites. As a result, the amount of the rubber material discharged from the discharge port is stably extruded.

With this supply, even if it is a rubber material that is difficult to bite, the root diameter of the screw is reduced toward the tip end side, so that the gap between the screw and the inner side surface of the cylinder becomes larger, so that it becomes easier to bite. Then, the bank of the rubber material staying in the supply port becomes small, and the penetration of the rubber material is promoted.
In other words, by promoting the bite amount of the rubber material that is difficult to bite, the rubber material also always has a stable bite amount, and thus a stable bite amount is always ensured. As a result, the amount of the rubber material discharged from the discharge port is stably extruded.

Further, in this portion, the diameter of the rotating shaft 6, which is the root diameter of the screw 2, is a reduced diameter portion 6a that is gradually reduced from the base end to the tip of the rotating shaft 6. That is, in the rotary shaft 6 located corresponding to the supply port 3, the groove depths d1 to d3 of the groove portion 8 between the spiral blades 7 adjacent to each other gradually increase from the base end to the tip (d1> d2). > D3).

In this extruder, when the screw 2 is rotated by a motor (not shown), a piece of tape-shaped rubber material is fed from the supply port 3 into the cylinder 1. Then, the rubber material is sheared and plasticized by the rotation of the screw 2 and is transferred to the tip end side along the axis of the cylinder 1 to be extruded from the discharge port 4 and discharged.

That is, the rubber material that is difficult to bite is supplied from the vicinity of the center of the rotating shaft 6 from the material supply range α (the left side portion in FIG. 1) of the supply port 3 on the tip side. With this supply, the rubber material that is difficult to bite is introduced into a deep portion of the bottom of the groove portion 8 of the screw 2. For this reason, even if the rubber material is hard to bite, the groove 8 has a deep bottom, so that it easily bites and the bank of the rubber material retained in the supply port 3 becomes small. As the bank becomes smaller, the rubber material that is hard to bite easily bites into the cylinder 1. That is, since the amount of bite of the rubber material which is hard to bite is promoted, a stable amount of bite is always secured, so that the discharge amount does not decrease.

That is, the rubber material that easily bites is supplied to a shallow place at the bottom of the groove portion 8 of the screw 2.
With this supply, the rubber material that easily bites is introduced into the shallow portion of the bottom of the groove portion 8 of the screw 2. For this reason, even if the rubber material is easy to bite, it is difficult to bite because the bottom of the groove portion 8 is shallow, and a large amount of biting prevents the rubber material once bited into the cylinder 20 from flowing back to the supply port 21. That is, a stable bite amount is always ensured by suppressing the bite amount of the rubber material that easily bites.

Therefore, the amount of bite does not greatly affect the difference in rubber material. Therefore, it is possible to always secure a stable bite amount of the rubber material without modifying the shape such as the depth of the supply port 3 or replacing the cylinder 1 with the supply port 3 having a different shape. As a result, a stable extrusion function can be exhibited.
