Structural Design and Analysis of an Automated Cutting Device for a Grass Carp Product Based on SolidWorks

When addressing the issue that the current market sales of fresh aquatic products, which are segmented into sections, mainly rely on manual operations, there are problems such as high labor intensity, low cutting efficiency, and uneven cutting. This paper designs an automated cutting device based on the commonly used grass carp as the object. Firstly, two efficient cutting schemes were proposed and compared. The optimized cutting scheme was designed using the SolidWorks software 2021. Then, three optimized schemes for the automatic clamping module, transmission module, and pushing module were designed. Subsequently, the structural design and calculation analysis of the key internal components were carried out to build the three-dimensional model of the automatic grass carp cutting device, and the cutting prototype was manufactured. Finally, an automated cutting prototype was fabricated based on the above-mentioned optimized design schemes, and relevant tests and analyses were conducted. The results showed that the prototype device can cut grass carp with a length of 300 ± 5 mm, with a processing capacity of 200 kg/h. The surface damage rate is less than 5%, and the cutting efficiency has been improved while the surface damage rate has significantly decreased. Therefore, the device manufactured through this design can meet the rapid processing, cutting, and various specific processing requirements of grass carp and other fresh aquatic products, providing a feasible solution for aquatic product cutting manufacturing equipment.
