Novel rubber pipe extruding machine

Abstract

The invention discloses a novel rubber pipe extruding machine which comprises a feeding barrel, a bearing, a shell and a rotary shaft. The rotary shaft is connected with the feeding barrel through the bearing in a matched mode; one end of the feeding barrel is provided with a feed inlet, and the other end of the feeding barrel is provided with a discharge outlet; the shell is internally provided with an annular barrel fixedly connected with the inner wall of the shell, and a mold core is connected in the annular barrel through a thread in a matched mode and penetrates through the shell; one end of the mold core stretches out of the shell, and the other end of the mold core penetrates through a through hole of a mold sleeve and aligned with the mold sleeve; the inner surface of the mold sleeve and the outer surface of the mold core form a discharge hole; a thread is arranged on the outer circular face of the mold core, and a mold core sleeve connected with the mold core through a thread in the matched mode is arranged on the outer circular face of the mold core; and the shell is provided with a hot water heat conduction layer and internally provided with a porous plate, and through holes are fully distributed in the porous plate. The novel rubber pipe extruding machine can improve the production efficiency.

Description

technical field [0001] The invention relates to the technical field of rubber production, in particular to a novel rubber tube extruder. Background technique [0002] The new rubber tube extruder, also known as extruder, is one of the important process equipment in the production of rubber products. In the processing and molding of rubber materials in the rubber industry, the new rubber tube extruder and calender are listed as the two leading production models. They are widely used and can process and manufacture various strips, tubes, rods, plates and other special-shaped rubbers. Materials, and with the development of science and technology, the cash new rubber tube extruder can produce sheet rubber, steel cord tape and metal, fiber wire and so on. [0003] The head of the traditional extruder realizes the production of rubber hose through the annular hole formed by the mold core and the mold sleeve. However, when it is necessary to produce rubber hoses of different thick...

AI Technical Summary

Problems solved by technology

[0003] The head of traditional extruder realizes the production of rubber hose through the annular hole formed by the mold core and the mold sleeve, but when it is necessary to produce rubber hoses of different thicknesses, it is necessary to start the head, replace the mold core and mold sleeve, and at the same time need to adjust the mold core and mold sleeve The concentricity of the hose is guaranteed to ensure that the wall thickness of the produced rubber hose is uniform, but each adjustment takes at least 30 minutes, and even 1 to 2 hours for unskilled operators. During this period, the rubber material continues to flow out through the nozzle. This causes a lot of waste of raw materials and labor, low work efficiency and poor quality stability
