Description

[Detailed Description of the Invention] The present invention relates to a device for removing residual material from a breaker plate in an extruder for extruding polymeric materials such as rubber and vinyl.

Breaker plates are available from various companies (
Any remaining material within the internal diameter (3-20 mm) must be removed.

Currently, one worker is assigned to use a drilling machine to remove the remaining material from each breaker plate one by one.

However, the holes in the breaker plate are 80-150.
The problem was that it took a lot of effort and time to extract the remaining material, and the workability was poor.

In addition, there was a drawback that the breaker plate was easily damaged by the aperture when removed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device for removing residual material from an extruder breaker plate, which can efficiently remove residual material.

Hereinafter, specific examples of the present invention will be explained in detail with reference to the drawings.

As shown in FIGS. 1 to 3, the apparatus for removing residual material from an extruder breaker plate according to the present invention has a frame 1, which has a pair of slide rails IA and IA.
A pair of arms IC and ID are slidably supported across B.

The screw shafts 2 and 3 are attached to the slide rail I on the arm IC and ID.
It is penetrated in a direction parallel to A and IB and is screwed together.

A handle 4, 5 is attached to the outer end of each screw shaft 2, 3, and a replacement joint 6.7 is attached to the inner end.

These members 1 to 6 and 7 constitute a cap support means 9, which will be described later.

A high-pressure cap 10 that closes one side of the breaker plate 8 is attached to the replacement joint 6.
It comes into contact with the periphery of one side of the plate 8.

An injection port 12 is formed in the high pressure cap 10 .

A cap 13 is attached to the replacement joint 7 to close the other side of the breaker plate 8, and the periphery of the opening side of the cap 13 is brought into contact with the periphery of the other side of the breaker plate 8. It looks like this.

The depth of the opening of the cap 13 is selected to be shorter than the thickness of the breaker plate 8.

A discharge port 14 is formed in the receiver cap 13.

Slide rails IA and IB have plate holder means 15A.
, 15B are supported, and these plate holders are supported by means 15A,
15B is adapted to receive the other side of the breaker plate 8.

Fluid such as water is fed into the high-pressure cap 10 at high pressure from a pump 16 as a pressurized fluid supply means through a pipe 17.

The operation of the pump 16 is controlled by a timer 17.

A buzzer 18 is connected to the timer 17.

A drain cock 19, a relief valve 20, and a pressure gauge 21 are connected to the pipe 17.

Further, a pressure switch 22 is connected to the pipe 17, and a control relay 23 is connected to the pressure switch 22 to control the pump 16.

Next, the remaining material removal operation using such an apparatus will be explained.

The outer diameter of the clogged breaker plate 8 is measured, and the high-pressure cap 10 and receiver are replaced and attached using the joints 6 and 7, respectively.

After that, place the clogged breaker plate 8 on the right side of the plate receivers 15A and 15B as shown in FIG. .

Similarly, the receiver brings the cap 13 close to the left side surface of the breaker plate 8, leaving a gap (approximately 2 to 3 mm) between them.
).

In this state, a fluid such as water is injected into the high pressure cap 10 using the pump 16 to fill the high pressure cap 10 with a high fluid pressure body (5
When a force of 0 to 150 kg/cm2) is gradually applied, the remaining material 24 such as plastic in each hole 8a of the clogging breaker plate 8 is pressurized and pushed out to the left in FIG.

At this time, the clogging play calf. Rate 8 has a remaining material 24 that is easy to remove and a remaining material 24 that is difficult to remove.

The remaining material 24 that has been pulled out quickly comes into contact with the cap 13 and is prevented from being completely pulled out from the hole 8a of the breaker plate 8. This prevents the pressure drop in the high pressure cap 10 and prevents all of the remaining material from being pulled out. The remaining material 24 in the hole 8a can be extruded.

In this way, if the timer 17 is set in advance for the time required to push out the remaining material 24 from all the holes 8a, the buzzer 18 will sound an alarm when the set time is reached, allowing you to know when pushing is complete. .

When the removal of the remaining clogged material 24 is near completion, the fluid in the high-pressure cap 10 is ejected from the hole 8a of the breaker plate 8 into the cap 13 and flows out from the discharge port 14.

In this state, the pressure inside the high pressure cap 10 decreases,
Pressure switch 22 detects this reduced pressure, and control relay 23 operates to stop pump 16.

In addition, if the pump 16 does not stop for some reason and the inside of the high pressure cap 10 is abnormally pressurized, the relief valve 20
operates to ensure safety.

When the pump 16 is stopped, the high pressure cap 10 and the receiver separate the cap 13 from the breaker plate 8, take out the breaker plate 8, and remove the remaining material 24 partially protruding from the breaker plate 8.

Remaining material 24 of breaker plate 8 with a different diameter from the previous one
When attempting to remove the high-pressure cap 10 and receiver that match the diameter, the cap 13 is replaced using the replacement joints 6 and 7.

Next, a comparison was made between the removal of remaining material using the device of the present invention and the removal of remaining material using a conventional drilling machine, and the following results were obtained.

Note that the receiver can also be used as a plate receiver if the cap 13 is made strong.

Further, in the above embodiment, an example in which a liquid is used as the fluid has been described, but a gas such as air can also be used as the fluid.

When using gas, all the clogging can be removed at once by applying high pressure gas to the clogging repaker plate at once by opening the cock.

As explained above, according to the apparatus according to the present invention, the remaining material from the base hole of the breaker plate can be efficiently extracted.
