Rubber tube extrusion device and method

Abstract

The invention relates to a rubber tube extrusion device and method. The rubber tube extrusion device comprises a machine body, a mold core, a mouth mold and a mounting lantern ring, wherein the mold core, the mouth mold and the mounting lantern ring are arranged close to one end of a discharge port of the machine body, a transition cavity is formed between the mold core and the mounting lantern ring, and a forming cavity is formed between the mold core and the mouth mold. The rubber tube extrusion device further comprises a connecting mechanism, wherein the connecting mechanism comprises a hollow screw rod, an air pipe, a powder pipe, a connecting piece and an air blowing piece; the connecting piece is connected with the inner side wall of a mounting column; one side, far away from the mounting column, of the connecting piece is connected with the mold core; a through hole is formed in the connecting piece; the hollow screw rod penetrates through the mounting lantern ring and communicates with the through hole; a discharge hole is formed in the mold core; one end, far away from the mounting lantern ring, of the hollow screw rod is connected with the air pipe; the powder pipe is arranged on the air pipe; and one end of the air pipe is connected with the air blowing piece. According to the rubber tube extrusion device and method, powder is blown to the inner wall of a rubber tube, so that the adhesive force between the inner walls of the rubber tube is reduced, the inner walls of the rubber tube are inconvenient to bond, then the rubber tube is convenient to carry out subsequent processing, and the processing efficiency of the rubber tube is improved.

Description

technical field [0001] The present application relates to the technical field of rubber hose forming, in particular to a rubber hose extrusion device and method. Background technique [0002] Rubber hose is a tube used for medium or gas transportation. It is mainly used in many fields such as supporting electrical appliances, electronics, hardware, ships, aviation, machinery, lighting and medical treatment. It is mainly formed by extruder during processing. , During the processing of the extruder, the material is first injected into the extruder to make the material fully plasticized, mixed evenly, and then shaped through the die of the extruder. [0003] The Chinese patent with the application number 201010157681.4 discloses a rubber screw meshing cold feeding extruder, including a frame on which the barrel of the plasticizing section, the barrel of the feeding section, the feeding device and the variable speed drive are sequentially installed. The device, the motor, and t...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned related technologies, the applicant believes that during the processing of the rubber hose, after the rubber material is processed through the barrel of the plasticizing section, because the inside of the rubber hose has a certain viscosity, the inner wall of the rubber hose is easy to adhere, and the adhesion position of the rubber hose needs to be separated. , affecting the processing efficiency of the rubber hose
