Novel energy-saving weight device of large internal mixer

Abstract

The invention discloses a novel energy-saving weight device of a large internal mixer, which relates to the weight field of internal mixers. With the development of the industry, especially the development of the tire industry, the enlargement of the internal mixer becomes the development trend. Because of the increase of the volume, if still fully adopting the structural design of small internalmixers, the problems in the aspects of feasibility, production efficiency, processing cost and the like are certainly brought in as a result of the enlarged volume of the components. The weight device of the internal mixer comprises a side bracket (7), a discharge door (6), a fixed weight (8) and a fluctuating weight (9), wherein the fixed weight is fixed on the side bracket (7). The invention avoids the problem of weight volume increase caused by the volume increase of the internal mixer, meets the operational requirements, effectively avoids the various problems resulted by the oversized weight, and lowers the cost.

Description

technical field [0001] The invention relates to a ballast of an internal mixer, in particular to a novel ballast device for reducing energy consumption of a large internal mixer. Background technique [0002] The internal mixer structure is as figure 1 As shown, it is mainly composed of pressing device, feeding device, banburying device, unloading device and locking device. The rubber material is put into the mixing room through the feeding door, and then under the action of the weight, the rubber material is pressed into the closed space composed of the mixing room, the discharge door and the weight, and through the rotation of the two rotors, the pressure of the weight Under the action, the rubber material is repeatedly kneaded by shearing, tearing, stirring and folding in this closed space to achieve the purpose of rubber mixing. [0003] The length L of the weight in the internal mixer of the general structure 1 and mixing chamber length L 0 basically the same. Howe...

AI Technical Summary

Problems solved by technology

[0009] 1. Due to the long length and heavy weight of the weight, it is necessary to increase the shaft diameter of the guide rod to improve the strength and rigidity of the guide rod. At the same time, the use of the original structure of a guide rod will make it difficult to guarantee the stability of the weight. The guide rod may be damaged due to uneven force during use

However, it is very difficult to install the structure of the two guide rods.

[0010] 2. If the weight adopts a water cooling structure, it is necessary to drill holes on the weight, and the length of the weight is too long, which will greatly increase the difficulty of processing, and at the same time increase the processing cost a lot

[0011] 3. If the weight is too long, the weight of the weight will increase, and the corresponding material cost will increase. At the same time, it will increase the burden on the power system of the pressing material, and the supporting cost will also increase.
