Rubber thread pipe extruder

Abstract

The invention discloses a rubber thread pipe extruder. The rubber thread pipe extruder comprises a feed cylinder, a bearing and a rotating shaft, wherein the rotating shaft and the feed cylinder are matched and connected through the bearing; a rubber inlet is formed in one end of the feed cylinder, and a discharge port is formed in the other end; a feed thread is arranged on the rotating shaft; a first separation plate and a second separation plate are arranged on the inner wall of the feed cylinder, and are positioned between the bearing and the feed thread; an annular column is arranged between the first separation plate and the second separation plate; the inner wall of the annular column is a conical surface; a sealing ring fitting the annular column through a conical surface is arranged in the annular column; a spring is arranged between the sealing ring and the first separation plate; the discharge port is a cylindrical port; a thread is arranged on the wall of the discharge port; a cooling tank is formed in the discharge port; and one end of the rotating shaft extends into the discharge port, and is leveled with the outer wall of the discharge port. The rubber thread pipe extruder can prevent rubbers from entering the bearing of the rotating shaft to damage the bearing, and improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of rubber machinery, in particular to a rubber threaded pipe extruder. Background technique [0002] Rubber threaded 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 rubber threaded tube extruder and the calender are listed as the two leading production models. Materials, and with the development of science and technology, cash rubber threaded pipe extruder can produce plate rubber, steel cord tape and metal, fiber wire and so on. [0003] The rotating shaft of the traditional rubber threaded pipe extruder rotates for a long time. After the sealing ring is worn, the rubber material will enter the bearing of the rotating shaft, damage the bearing, and the rotating shaft will fail, causing the rotating shaft to not operate normally, thus affecting the rubber threa...

AI Technical Summary

Problems solved by technology

[0003] The rotating shaft of the traditional rubber threaded pipe extruder rotates for a long time. After the sealing ring is worn out, the rubber material will enter the bearing of the rotating shaft, damage the bearing, and the rotating shaft will fail, causing the rotating shaft to not operate normally, thus affecting the performance of the rubber threaded pipe extruder. Production efficiency and product quality, but also increased maintenance costs and production costs

[0004] The existing production of rubber threaded pipe requires rubber to be extruded from the rubber pipe, and the rubber pipe is processed to finally obtain a threaded pipe, which increases the production cost of the rubber pipe and reduces work efficiency
