摘 要：
为了对6PYL-305型剖鱼机进行优化以提高其剖切质量,以鲢鱼和鳊鱼为研究对象对其关键部件和工艺参数进行了试验,研究喂料撞块位置、鳊鱼夹片安装倾角、鲢鱼出料滑槽高度、刀具类型等因素对剖切质量的影响。试验结果表明:剖切鲢鱼时最佳撞块位置为距离料斗右侧(225±5)mm、剖切鳊鱼时为(160±5)mm;剖切鳊鱼时夹片最佳安装倾角为16°;鲢鱼出料滑槽的最佳高度为65mm;齿高3mm的小齿刀盘作为剖切刀盘综合效果最佳,鲢鱼鱼体剖切率可达(83.90±2.31)%,剖切损失率仅为(0.62±0.15)%,鳊鱼的剖切损失率为(0.85±0.28)%,剖切面较光滑,剖切后的鱼体内脏可以很方便地去除。采用优化后的工艺参数,剖鱼机性能以及稳定性得到了良好改善。

摘 要：
In order to improve the processing quality of the 6PYL-305 fish shearing machine developed,based on the experiments of the key parts and the technical parameters of the machine,the effects of the collision block of feeding structure,clip angle of fresh-water bream fixing,discharge chute height of the silver carp and cutter type on the processing quality were studied by using the silver carp and fresh-water bream as research objects.The results indicated that the optimal position of the feeding collision block was (225±5) mm from the hopper for silver carp and (160±5) mm for fresh-water bream,the optimal clip angle of fresh-water bream fixing was 16°;The optimal height of discharge chute for silver carp was 65 mm.Cutter with tooth of 3 mm height got a cutting rate of (83.90±2.31)% on silver carp fish while the losing rate of weight was (0.62±0.15)%,and a cutting rate of 100% on the fresh-water bream while the losing rate of weight was (0.85±0.28)%.In general,the cutting surface of both sheared fish was smooth,and the offal can be easily removed for convenience subsequent processing.After optimization,the performance and stability of the machine were improved.
