Description

Technical Field

[0002] In the deep processing of specific agricultural products, material morphology is a key production process link, which directly affects the stability of product morphology and physical properties, and thus determines the market acceptance of the end product. Traditional production methods rely on manual work to complete material positioning, shaping and other processes, and there are problems such as low operating efficiency and insufficient standardization leading to fluctuations in product qualification rates. With the leap of science and technology and the increasing maturity of automation technology, this field is gradually moving towards the path of automation and intelligence.

[0003] Although the existing automated molding system has built a basic transportation circulation system, it still has some shortcomings: 1) Low space utilization: The circular conveying layout requires complex series connection of multiple conveying modules, which occupies a large area and limits the scalability of the production line; 2) Poor production continuity: The transport carrier and the main conveyor line are designed to be separated, and secondary positioning and connection are required at multiple process nodes, resulting in interruptions in the production rhythm and making it difficult to meet the needs of high-speed continuous production; 3) Poor thermal processing efficiency: The heating equipment uses roller conveying and heating tube radiation heating, which has low heating efficiency, long heating stroke, high energy consumption, and lack of humidity control, which can easily lead to hardening of the material surface; 4) Human involvement has not been eliminated: The loading and unloading stages rely on human intervention, making it difficult to achieve true full-process automation, which restricts the improvement of production capacity and yield.
