Description

Technical Field

[0001] This utility model relates to the technical field of foam material production equipment, specifically to a raw material preheating and conveying structure for the production of micro-crosslinked foam materials. Background Technology

[0002] Micro-crosslinked foamed materials, with their excellent mechanical properties, heat resistance, and cushioning performance, are widely used in packaging, automotive interiors, and building insulation. In their production process, the preheating treatment of raw materials is a crucial step affecting the quality of the final product. The raw materials need to be heated to a specific temperature range during transportation to ensure sufficient mobility of the molecular chains, laying the foundation for subsequent crosslinking and foaming reactions. Therefore, heating equipment is required to complete the preheating and transportation of the raw materials.

[0003] Utility model patent CN223267664U discloses a raw material conveying device, including a conveying component and a vacuum component for conveying raw materials. The conveying component includes a pipe, with at least two dehumidification components spaced axially along the pipe to expel moisture from the conveying component. The dehumidification component includes a heating element and a drying element. The heating element is located at the top of the pipe, with an exhaust port at its top. The heating element absorbs sunlight to generate heat, heating the air at the top of the pipe, which then rises and exits through the exhaust port. The drying element connects the inside of the pipe to the outside air, allowing outside air to be dried before entering the pipe. When the heating element is not in operation, the vacuum component provides suction to expel air from the top of the pipe.

[0004] The raw material conveying device provided by the aforementioned patent can heat and convey raw materials, but it has significant shortcomings in the actual production process of micro-crosslinked foamed materials. In the production of micro-crosslinked foamed materials, the raw materials must first be mixed at high speed using a high-speed mixer, and the mixing process must simultaneously preheat the raw materials before transferring the mixed materials to an extruder. However, the existing raw material conveying device can only achieve heating and conveying of the raw materials independently, lacking the function of preheating and mixing them. This necessitates separate raw material mixing, impacting the production efficiency of micro-crosslinked foamed materials. Summary of the Invention

This structure aims to improve the problem that while existing raw material conveying devices can heat the raw materials, they cannot preheat and mix them, which requires separate mixing of the raw materials and affects the production efficiency of micro-crosslinked foamed materials.
