带式夹送淡水鱼剖鱼机的研制

摘要

This study is about the design and manufacture of a new belt-clamp freshwater fish slitter which is based on the research of characteristic parameters of hypophthalmichthys molitrix..The fish slitter consists of machine frame,nip-deliver system,cutting system. The key processing parameters of fish slitter can be adjusted,such as belt spacing of nip-deliver system,belt speed,circular saw height of cutting system.The rated power is 3.7 kW,consist of 1.5 kW cutting system motor and 2.2 kW nip-deliver system motor.The final results of experiments with (1.5±0.25)kg hypophthalmichthys molitrix:The level of belt spacing has significant impact on charging,cutting and discharging;it can be 100% success rate when the level of belt spacing is L=40 mm.The level of circular saw height has significant impact on cutting quality,for the fish fully cut open from the head to the tail requires circular saw height not more than 190 mm,for com-plete preservation of the swim bladder requires circular saw height not less than 210 mm,for not to destroy the fish bile requires circular saw height not less than 180 mm.The fish slitter running stable and has the best cutting quality when the level of belt spacing of nip-deliver system is L=40 mm,the level range of circular saw height of cutting system are from 180 mm to 190 mm.%依据鲢鱼的结构特征和对产品品质的要求,研制了一款带式夹送淡水鱼剖鱼机,并以鲢鱼为试验对象进行了剖鱼试验。该剖鱼机由机架、夹送系统、剖切系统组成。夹送系统皮带间距、皮带转速、剖切系统刀盘高度等关键部件工艺参数均可调节,配套功率共为3.7 kW,其中剖切系统电机1.5 kW,夹送系统电机2.2 kW。以(1.50±0.25)kg 鲢鱼为剖切对象所进行的试验结果表明：皮带间距对进料、剖切、出料均有显著影响,皮带间距40 mm 时,可以实现100%顺利进料、平稳剖切和顺利出料；刀盘高度则对剖切质量影响显著,从鱼头到鱼尾完整剖开鱼体要求刀盘高度不高于190 mm,完整保留鱼鳔要求刀盘高度不低于210 mm,不破坏鱼胆要求刀盘高度不低于180 mm。皮带间距取40 mm,刀盘高度取180~190 mm 时,剖鱼机运行稳定且剖切效果最优,处理速度可达1200尾/h。
