Abstract

The invention discloses double-screw extruding equipment for producing a thin film. The double-screw extruding equipment comprises sealing barrels, sealing seats, an exhausting device, a sealing ring and double-screw shafts, wherein the double-screw extruding equipment is composed of nine sections of the sealing barrels; the sealing seats are arranged in front and back of the sealing barrels; the double-screw shafts are arranged in nine sections of the sealing barrels and penetrate through the sealing barrels, and penetrate through the final section of the sealing barrel by the sealing ring; the exhausting device is arranged on the second section of the sealing barrel from left to right; a vent hole is formed in the fourth section of the sealing barrel from left to right; a secondary feeding hole is formed in the side face of the sixth section of the sealing barrel from left to right and a vent hole is formed in the secondary feeding hole; and a vent hole is formed in the ninth section of the sealing barrel from left to right. The double-screw extruding equipment has the advantages that the structure is compact, the extrusion efficiency is high, the cost of raw materials is saved, the maintenance cost is reduced and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of film processing, in particular to a twin-screw extruder used for film production. Background technique [0002] Synthetic paper is made by using chemical raw materials such as olefins and adding some additives. It has soft texture, strong tensile strength, high water resistance, light resistance to cold and heat, resistance to chemical corrosion, no environmental pollution, and good air permeability. , Widely used in the printing of high-end artworks, maps, picture albums, high-end books and periodicals, etc. Extrusion equipment currently used in domestic production equipment has the following problems or defects: [0003] (1) The diameter of the screw of the ordinary screw extruder is relatively large, and it is easy to have direct metal-to-metal contact with the barrel; [0004] (2) The thrust bearing has a short service life; [0005] (3) The trimmed chips can be fed directly back into the extruder....
