Description

Technical Field

[0001] The utility model relates to the technical field of PVC production equipment, in particular to a mixing device for PVC foam boards. Background Art

[0002] The main component of PVC foam board is polyvinyl chloride, which is used in many industries such as building materials, packaging, and medical care. PVC foam board has become a popular and widely used synthetic material today because of its unique characteristics such as waterproof, fire-resistant, and easy to form, as well as its simple production process. In the process of producing PVC foam board, workers are required to first pour the powder into the powder feeding device, and then the pneumatic conveying device works and sucks the powder in the powder feeding device into the high-temperature stirring device. After the high-temperature stirring device has fully stirred the various powders, workers are required to transfer the high-temperature mixture to the powder cooling and stirring device for cooling, and finally transfer it to the extruder. The mixing process requires multiple transfers, which wastes human resource costs and has low production efficiency. In addition, since the moisture absorbed by the powder during storage is separated and attached to the powder after the heating and cooling process, it affects the quality of subsequent extrusion.
