Description

Technical Field

[0001] The utility model relates to the technical field of cooling of cold mixers, and more specifically to a cooling mechanism for cold mixers. Background Art

[0002] Cold mixer is a kind of equipment used for mixing and plasticizing rubber, plastic and other materials. Its working principle is to squeeze, fold and shear the materials through the rotation of double rollers in the roller drum to achieve the effect of uniform mixing, plasticization and melting. Cold mixer is widely used in rubber industry, plastic industry and other fields to improve production efficiency and product quality.

[0003] Cold mixers are usually equipped with cooling mechanisms to reduce the heat generated during the mixing process and ensure that the temperature of the mixture is stable within an appropriate range. The cooling mechanism usually includes a cooling water circulation system or a cooling fan system, which removes heat by circulation or blowing to keep the temperature of the equipment and the mixture constant. This helps to improve production efficiency, extend the service life of the equipment, and ensure stable quality of the mixture.

[0004] When the existing cooling mechanism for cold mixers is cooling, the air stays in the refrigeration box for too short a time, resulting in too short a contact time between the air and the refrigeration plate, making the refrigeration effect poor and affecting the refrigeration effect; when the existing refrigeration plates are installed, most of them are installed and disassembled by screws, and the installation and disassembly process is relatively cumbersome, resulting in poor convenience in replacing and repairing the refrigeration plates. For this reason, we propose a cooling mechanism for cold mixers. Utility Model Content
