Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus C for manufacturing cloth-filled rubber sheets 1 to 1, which are made by laminating rubber sheets and cloth.

Conventionally, a rubber material in the form of a plasticized lump is supplied to a rubber material in the form of a plasticized block, and a strong squeezing force is applied to the rubber material. It is being gradually expanded.

In this case, due to the lumpy rubber scraping o'31, the
- The rolls are pushed up in the direction of separating from each other at the center, the roll axis is elastically deformed, and the distance between the rolls in the medium heat section is expanded. 7. It is extremely difficult to make the sheet uniform with this J:uni calender roll, and the width of the J render roll is narrow like a diaphragm sheet, so It is not suitable as a means for producing a thin rubber sheet 1- with a uniform thickness. In addition, since the rubber material is strongly pinched between the rolls to form it, the power source must also be large.

Therefore, it is an object of the present invention to provide an apparatus that does not require a large power source such as a calender roll, and can easily manufacture diaphragm sheets with uniform thickness and thinness. It is covered.

That is, the apparatus of the present invention includes an extruder that plasticizes rubber material, a head that takes a die into the extrusion tube, a rectifier plate that adjusts the flow rate of rubber supplied to the die, and a rubber A die that presses the sheet 1 to 1, a pull +17 re-roll that takes over the rubber sheet extruded from the die, and a lamination I that can paste the rubber sheet I ~ and IJ! A winder takes up the rubber seal 1 and the seal 1 for the diaphragm.

The present invention will now be explained by the illustrated embodiments.

In Figure 1, J3 and 1 are rubber hands Δ that were softened and melted in the extruder.
Continuously supply the liquid with a screw or the like.

] 111 A rectifying plate 3 is attached to the head 2 formed at the tip of the projecting pier 1.
J3 and die 4 are taken. In the rectifying plate 3, as shown in FIG. Rubber JA supplied by
Among il+, the material flowing along both sides of the supply passage faces resistance from the side walls and has a low C flow rate, so the C flow rate is smaller than that at the center. For the rectifying hole 31, the width of the opening on both sides is adjusted using a comb.
'' has the effect of reducing the flow rate at both ends to the center. As shown in FIG. 3, the rectifying holes 3'1 have a plurality of holes arranged in close proximity to each other, and the diameters of the holes on both sides may be larger than those of the holes in the medium heat section. The die 4 forms an extrusion port (not shown) for extruding the rubber material that has passed through the rectification hole 31 into a sheet. The opening width of "Extrusion 1" was uniform. G takes over [
1, the rubber seal 5 extruded from the die 4 is taken up at a predetermined speed. Reference numeral 7 denotes a hole 1 for pasting the rubber sheet 5 and the cloth 8 together. Reference numeral 9 denotes a trough roll for removing the laminated sheet J-10 for die-11 and noram.

As mentioned above, in the device made in 14, the extrusion
, the monthly profit of the supplied rubber is 111' on the rectifier plate 3! Flow hole 3
As mentioned above, the flow f + "l Lt on both sides becomes larger than the center part. It is then supplied to the extrusion hole of the die 4 and extruded. At this point, Rectifier hole 3
The extrusion of the rubber material 11 from both sides of the rubber material 11 (when passing through the rubber material 1, there is resistance at both ends of the rubber material 11) is reduced, and as a result, the central part J3 and both sides are uniform. The head 2 of the extruder 1 is extruded through the die at a flow rate of
When the rubber sheet is directly supplied to the extruder 1 of the tie 4, the flow rate of the rubber sheet from both sides becomes smaller at the center of the extrusion port, and as a result, the flow rate of the rubber sheet from both sides becomes smaller. The part is W, and the thickness on both sides J: becomes thicker. In the present invention (,
By installing the second rectifying plate 3 upstream of the upper die,
The rubber sheets 1 to 1 extruded from the die 4 maintain a uniform thickness even after extrusion.

The rubber seal 1 and 5 having a uniform thickness are taken up at a predetermined speed by a take-up [1-ru 6] and adjusted to a predetermined thickness.

Then, as described above, paste 5 to the rubber sheet 1 which has been adjusted to a uniform predetermined thickness.
-, and C is wound up on the winding board 9.

As mentioned above, in the present invention, an extruder is used, and a current plate is installed just before the die. The texture is uniform. Therefore, just by adjusting the speed of the call, rubber sheets 1 to 1!7 of a uniform predetermined thickness can be made. This gives you a sheet for use.
