Experiment on optimizing technical parameters of fish shearing machine

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.
