中文摘要:针对鲜切果蔬包装机输送机构作业时包装物料损伤和滑移的问题,分析了输送机构对包装盒压缩变形原理,通过PET包装盒的压缩试验,得到了包装盒及盒内的果蔬产品避免造成机械损伤的条件,PET包装盒压缩位移应在10mm以内,包装机输送机构压缩力应在5~15N之间。采用参数化建模,通过有限元仿真分析了输送机构对包装盒压缩变形的过程及机理,分析了包装盒的易损伤位置及原因。根据压缩试验及仿真分析,以滑移率为指标,进行正交试验,确定最佳参数组合:包装盒质量为19g,立式输送带对包装盒的压缩位移为8mm,输送带速度为0.25m/s,在包装盒及鲜切果蔬不压缩受损的同时PET包装盒和输送机构有较好的输送同步性。

Abstract:In order to decrease the damage and slippage of packaging material during the operation of conveying mechanism of fresh cut fruit and vegetable packaging machine, a study was conducted. In this work, the compression deformation principle of the packaging boxes compressed by the conveying mechanism was analyzed. Through compression test of PET packaging boxes, the force of the conveying mechanism should be between 5N and 15N, and the compression displacement should be less than 10mm, which could avoid mechanical damage of packaging boxes and fruit vegetable products. Then, based on parametric modeling, the process and mechanism of the compression deformation of the packaging boxes were analyzed by the finite element simulation. The easy damage position of the packaging boxes and the reason were analyzed. According to the above experiment and analysis, the quality of packaging boxes, the compression displacement and the speed of the vertical belt conveyors were selected as the orthogonal test factors. When the quality of packaging boxes was 19g, the compression displacement between the vertical belt conveyors and the packaging boxes was 8mm and the speed of the vertical belt conveyors was 0.25m/s, the results showed that the slip rate was 0.043%. Under this condition, there was no compressed damage on packaging boxes and fresh cut fruits and vegetables. Meanwhile, good transport synchronization was occurred between PET packaging boxes and conveying mechanism.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
