Abstract

The invention discloses a machine head of a rubber supply extruder of a three-roller calender. The machine head comprises a mold body which consists of a movable machine head mold and a fixed machine head mold, wherein the fixed machine head mold is arranged at a machine head cylinder opening of a pin cold feed extruder; the movable machine head mold is arranged on a mold opening and closing device; under a mold closing state, the mold body is locked by a mold locking device; a machine head opening is formed in the movable machine head mold and is provided with a small semicircular arc, a semicircular arc or a large semicircular arc which is downward and bilaterally-symmetric; the arc length of the machine head opening corresponds to the width of a wide-amplitude extrusion rubber tape, and the arc width of the machine head opening corresponds to the thickness of the wide-amplitude extrusion rubber tape; a material supply frame supplying rubber to the three-roller calender is arranged on an extrusion path of the wide-amplitude extrusion rubber tape, and the position of the material supply frame corresponds to the flattening spreading part of the wide-amplitude extrusion rubber tape. An extrusion calendering rubber supply path is greatly shortened, the temperature loss is small in the conveying process of rubber sheets, and the calendered rubber sheets are dense, uniform in thickness, smooth and flat in surface, bubble-free, and high in product quality.

Description

(1) Technical field: [0001] The invention relates to conveyer belt film extruding and calendering equipment, in particular to a three-roll calender machine head for rubber feeding extruder. (two) background technology: [0002] Conveyor belt is one of the important rubber products in the rubber industry and is widely used in the transportation of various materials. [0003] The conveyor belt is made of cover rubber, middle rubber and multi-layer film, and then vulcanized by a flat vulcanizing machine. Film production equipment is composed of pin cold feed extruder, three-roll calender and other auxiliary equipment. The film is produced by the calendering method. When the calender produces the film, the extruder supplies the glue, and the head is the molding part of the extruder. The function of the extruder is to change the rubber material from a spiral motion to a linear motion, extrude the rubber material under a certain pressure, and extrude it through the machine head ...
