ものが公知である。Conventionally, in a rubber kneading machine, as shown in FIG. 1, rubber is fed into a lower kneading section 2 having a pair of rotors 1, 1 from an input port 3 in the middle, and a cylinder in a presser cap 4 in the upper step. It is known that a weight 5 is used to apply weight to the introduced rubber and push the rubber down into the kneading section 2 during kneading.

By the way, the cylinder 6 of the pressing part 4 raises and lowers the cylinder weight 5 between the raised position A, the pressed position B, and the pressed position C, and for pressing from the pressed position B to the pressed position C, for example, 6 cylinder weights are used. Since an air pressure of kg/cni is required, conventionally the same amount of air pressure was supplied over the entire stroke of the cylinder 6, resulting in wasteful air consumption.

したものである。The present invention has been made in view of the above-mentioned conventional problems.
Air pressure for pressing is not required for lifting and lowering between the raised position and the pressed down position, which accounts for 70% of the total stroke.
For example, focusing on the fact that an air pressure of 1 kg/crA is sufficient, the cylinder is constructed of a small diameter cylinder for between the raised position and the pressed position, and a large diameter cylinder for between the pressed position and the pressed position. Moreover, a locking mechanism is installed to lock the large diameter cylinder in the depressed position, reducing the stroke by 30% of the total stroke.
Rubber can be pressed against the kneading section using only a large diameter cylinder.

以下、本発明の実施例を添附図面について詳細に説明す

In the light load pressure range between the push-down position and the push-down position, a small diameter cylinder is used to raise and lower the load, and in the high load pressure range between the push-down position and the push-down position, a locked large-diameter cylinder is used to raise and lower the lift. As shown in the figure, it is no longer necessary to supply the same amount of air pressure regardless of the light and high load pressure ranges, and the air cost can be reduced by about 40%.
