Description

Technical Field

[0001] The present invention relates to the field of assembled building equipment, in particular to a sandwich composite wall panel packaging platform. Background Art

[0002] As a new industry in the construction sector, prefabricated buildings can be mass-produced in a standardized manner. They offer numerous advantages, including reliable quality, energy conservation, environmental protection, low construction effort, and reusability, making them widely used in modern architecture. Sandwich composite strip wall panels, as a key component of prefabricated buildings, enable rapid construction or spatial isolation in modern buildings. They are low-cost, easy to assemble, and can meet a variety of operational requirements. After completing the entire production process, sandwich composite strip wall panels require film wrapping to effectively prevent the infiltration of dust, moisture, and other harmful elements from the air during transportation. Currently, wrapping methods are mainly divided into manual wrapping and machine wrapping. Manual wrapping is inefficient and suitable for small batches, while machine wrapping is more efficient and provides uniform wrapping. However, existing machine wrapping equipment suffers from problems such as excessively thin film wrapping and damage during transportation due to the impact of the movement between the wall panels due to bumps. Designing a device that can increase the wrapping thickness and strengthen the film's fastening force has become an urgent engineering challenge in the industry. Summary of the Invention
