Description

Technical Field

[0001] The utility model discloses a feeding station, belongs to the technical field of polyurethane foaming, and specifically relates to an IBC feeding station for a polyurethane foaming machine. Background Art

[0002] Polyurethane foaming is a common material preparation method, usually used to produce foam plastics, insulation materials, filling materials, etc. The following is a brief process of polyurethane foaming:

[0003] Raw material preparation: The raw materials for polyurethane foaming usually include isocyanate (such as MDI), polyether or polyester polyols, additives (such as catalysts, foaming agents, etc.) and gas foaming agents.

[0004] Mixing reaction: Mix isocyanate and polyol in a certain proportion, add appropriate amount of additives, and carry out mixing reaction under certain conditions (such as temperature and pressure). This reaction process is called the formation of polyurethane prepolymer and will generate heat.

[0005] Foaming process: Add gas foaming agent to the prepolymer after mixing reaction, and add appropriate amount of foaming agent. Under specific temperature and pressure, the prepolymer begins to foam and expand to form polyurethane foam.

[0006] Curing and molding: Polyurethane foam gradually solidifies during the foaming process to form a material with a certain shape and structure. The foam can be molded or cut as needed.

[0007] Post-processing: After the foam is formed, some post-processing processes may be required, such as removing surface irregularities, trimming edges, etc.

[0008] The polyurethane foaming process can be adjusted and optimized according to different needs and applications to obtain the desired properties and characteristics.

[0009] In foaming production, the foaming machine is on the platform, or the foaming machine is too far from the feeding area, and the weather and humidity will affect the stability of feeding. This equipment can be connected with the foaming machine. Except for the manual operation of changing the barrel, the rest is fully automated. The structure of this equipment can also solve the problem of unsmooth feeding caused by temperature and humidity. It reduces personnel costs and improves production stability. Utility Model Content

The second upper and lower cylinders 16 drive the stirring motor 28 group 17 to move up and down. When replacing the second barrel 21, the second upper and lower cylinders 16 drive the stirring rod 27 to rise. After replacement, the stirring motor 28 group 17 descends and inserts into the second barrel 21 to rotate to prevent sedimentation in the barrel. The second diaphragm pump 18 provides suction and transports the raw materials to the second barrel 21. The second diaphragm pump 18 is surrounded by heating belts, and the temperature can be maintained at about 60°C. In winter, it can solve the problem of not being able to add materials due to the high viscosity of the raw materials due to the low ambient temperature. The flip table 19 can be driven by the flip cylinder 20 to facilitate the evacuation of the raw materials in the barrel.
