Description
Technical Field
[0001] This utility model relates to the field of filling device technology, and in particular to a polyurethane compound filling device. Background Technology
[0002] Polyurethane materials, with their excellent wear resistance, oil resistance, high elasticity, and high strength, are widely used in many fields such as building insulation, automobile manufacturing, furniture and home furnishing, footwear and textiles. Taking the construction industry as an example, rigid polyurethane foam, as a high-efficiency insulation material, is widely used in wall insulation and cold storage insulation. In the automotive industry, polyurethane foam is used in seats and dashboard interior parts to improve ride comfort and safety. With the continuous growth in demand for polyurethane products from various industries, the production scale of polyurethane composite materials is constantly expanding. As a key link in the production of polyurethane composite materials, the performance of filling equipment directly affects product quality, production efficiency, and corporate economic benefits. To meet the needs of high-quality development in the polyurethane industry, the development of new filling devices that are high-precision, high-efficiency, easy to clean, and safe and reliable has become an industry consensus. New devices need to combine advanced sensing technology, automation control technology, and materials science achievements to solve the technical bottlenecks of traditional devices and promote the intelligent and green development of polyurethane composite material production.
[0003] Traditional polyurethane compound filling equipment has many problems in practical applications. In terms of filling accuracy, early equipment mostly adopted volumetric metering methods, such as piston metering pumps and gear pumps. These metering methods achieve quantitative filling by controlling the volume of the material. However, polyurethane compounds are usually composed of multiple components such as polyols and isocyanates. Their viscosity and density are significantly affected by temperature and storage time. At lower temperatures, the viscosity of the material increases, and the mass of the material in the same volume decreases, resulting in a deviation between the actual filling volume and the set value. The error range can reach ±5%, which is difficult to meet the production requirements of high-precision products. This insufficient filling accuracy not only causes material waste, but also affects the performance consistency of polyurethane products. For example, in the production of thermal insulation boards, inaccurate compound ratios can lead to unstable thermal insulation performance of the boards.
[0004] However, most traditional polyurethane compound filling devices do not have a stirring mechanism. The original design intention was to simplify the structure and reduce costs. These devices simply transport the material in the storage tank directly to the filling head through pipelines. During the material transportation process, limited mixing is achieved solely by the fluid flow within the pipeline. However, polyurethane compounds are highly reactive, and some components may undergo slow chemical reactions when left to stand. For example, isocyanate may produce prepolymers when it comes into contact with trace amounts of moisture. When the device is not equipped with a stirring mechanism, these locally reacting materials cannot be dispersed evenly in time, forming lumpy or flocculent impurities. Utility Model Content
[0005] The purpose of this invention is to provide a polyurethane compound filling device that solves the problem that most traditional polyurethane compound filling devices do not have a stirring mechanism.
