Description

Technical Field

[0001] The utility model relates to the technical field of rubber internal mixers, in particular to a rubber internal mixer. Background Art

[0002] Rubber products cannot be made of pure rubber alone. In order to make the products have specific physical and mechanical properties and facilitate the processing and molding of the products, a certain amount of other inorganic and organic compounds must be added to the raw rubber. These compounds are the so-called rubber compounding agents. The process of using mechanical methods to disperse the rubber compounding agents completely and evenly into the raw rubber is called the compounding and mixing of the rubber. Therefore, a special rubber internal mixer is required for processing.

[0003] The existing rubber internal mixer still has some problems when in use. First, after the rubber liquid is mixed with the organic compound, it needs to be plasticized and formed. The traditional method requires transportation and transfer to the device that needs plasticization for operation, which increases the steps and is inconvenient to operate, reducing the processing efficiency. Secondly, when mixing the rubber liquid, the rubber is easy to stick to the furnace wall, which brings inconvenience to cleaning. The traditional scraping method is relatively fixed, and the rubber liquid is easy to accumulate in one place, causing blockage, reducing the cleaning effect, and also reducing the overall use effect of the internal mixer.

The pull-out plate 7 is mainly used to facilitate the removal of the lower plasticizing top plate 23 to the outside and the removal of the plasticized rubber. Two groups of support frame plates 9 are symmetrically installed between the installation support box 2 and the installation support base 3. The support plate frame 9 mainly plays the role of supporting the installation support box 2.

[0039] The working principle and use process of the utility model are as follows: first, when in use, the cleaned rubber raw material is conveyed to the heating inner furnace 11 inside the internal mixing furnace body 1 through the feeding mechanism 5, and the heating mechanism 10 is turned on at the same time, so that the inside of the heating inner furnace 11 is continuously heated to dissolve the rubber into a liquid state, and the required organic compound is injected into the internal mixing furnace body 1 through the injection pipe 8 to mix with the rubber raw material, and the driving motor 12 is turned on to drive the rotating rod 13 to rotate, which drives the stirring rod 14 to rotate and also drives the scraper 16 on the connecting plate 15 to rotate and scrape along the inner wall of the heating inner furnace 11. At the same time, due to the setting of the extrusion spring 32 in the stirring rod 14 and the movable top plate 30 connected to the connecting plate 15, the elastic force of the extrusion spring 32 causes the movable top plate 30 to continuously shrink, driving the connecting plate 15 and the scraper 16 to vibrate, and the inner wall of the heating inner furnace 11 is scraped. Vibration-type scraping improves the scraping effect and prevents clogging, which not only improves the cleaning effect, but also improves the overall use effect of the internal mixer. Secondly, after the stirring is completed, the control valve 18 is opened, and the mixed rubber liquid is injected into the lower plasticizing top plate 23 through the discharge pipe 17 and the injection hole 26 in the upper plasticizing plate 21, and the electric telescopic cylinder 20 is turned on, so that the telescopic rod 22 drives the supporting card plate 24 and moves the lower plasticizing top plate 23 on it toward the upper plasticizing plate 21, thereby squeezing the rubber liquid. At the same time, the two sets of exhaust mechanisms 19 are operated to continuously circulate and cool the hot air inside the plasticizing box 6, so that the rubber liquid is quickly cooled and formed. At the same time, the connecting hole 25 and the annular cooling bin 28 are connected, which facilitates the entry of cold air into the interior of the upper plasticizing plate 21, thereby improving the cooling efficiency. This not only saves operating steps, but also improves the convenience of operation and the processing efficiency.

[0040] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
