Rubber and plastic extruder

Abstract

The invention discloses a rubber and plastic extruder. The rubber and plastic extruder comprises a feed opening, a discharge opening, a first cylinder, a first extrusion screw, a first reduction gearbox, a first motor, a second cylinder, a second extrusion screw, a second reduction gearbox, a second motor and a connection channel, wherein the first extrusion screw is mounted in the first cylinder and connected with the first reduction gearbox; the first reduction gearbox is connected with the first motor; the second extrusion screw is mounted in the second cylinder and connected with the second reduction box; the second reduction gearbox is connected with the second motor; the feed opening is arranged at the input opening of the first cylinder; the discharge opening is arranged at the output opening of the second cylinder; the connection channel is connected between the output opening of the first cylinder and the input opening of the second cylinder. The rubber and plastic extruder adopts a two-stage serial structure, so that the structure of a traditional single screw extruder is simplified, the overall lengths of the screws are reduced, convenience is brought to the design, manufacture, maintenance and use of the rubber and plastic extruder, and impacts on finished product quality are reduced.

Description

technical field [0001] The invention relates to a rubber and plastic extruder. Background technique [0002] In plastic extrusion molding equipment, the plastic extruder is usually called the main machine, and the subsequent equipment plastic extrusion molding machine that is matched with it is called the auxiliary machine. The plastic extruder can be matched with various plastic molding auxiliary machines such as pipe, film, handle material, monofilament, flat wire, packing belt, extruded net, plate, profiled material, granulation, cable coating, etc., to form various plastic extruders. A molding production line is produced to produce various plastic products. Therefore, plastic extrusion molding machinery is one of the indispensable models in the plastic processing industry. In actual production, the rubber and plastic raw materials generally enter the barrel from the feed port of the barrel, and under the action of the screw, they are heated and extruded to be plasticiz...
