Description

Novel crude rubber press

Technical Field

The utility model relates to the technical field of pressing machines, in particular to a novel raw rubber press.

Background

On the STAR line (i.e., the pressure sensitive adhesive line), the stock is first forced from a stock vat into an agitator by a press. As shown in fig. 1, before the raw materials enter the mixer 500, a material barrel (not shown) for storing GUM (i.e. raw rubber) is placed in a hoop (not shown) of the press 300 and fixed by the hoop, the driving oil cylinder 304 of the press 300 presses downwards, and the GUM enters the mixer 500 from a discharge hole 316 at the rear end of a platen 306 of the press 300, a quick-connection hose 301, a DN100 solenoid valve 303, an elbow 305, and a DN100 × 150 reducer 307.

However, since the piston rod 314 of the driving cylinder 304 is directly connected to the center of the platen 306, the horizontal distance between the press frame 310 of the press 300 and the material barrel is only 180mm, and therefore, only the small-diameter hose (outer diameter 160 mm) of DN100 can be connected as a quick-connection hose, but the large-diameter hose (outer diameter 240 mm) of DN150 cannot be connected. A circle 400 shown by a dotted line in fig. 2 indicates a position state when the large-diameter hose of DN150 is connected, and it is apparent that the diameter of the large-diameter hose of DN150 interferes with the piston rod 314, and thus the large-diameter hose of DN150 cannot be connected in the conventional press 300.
