Design And Test Of Clip-on Type Fish Cutter

The cutting and destaining of fish bodies is the primary link in the pretreatment and processing of freshwater fish.In view of the lack of domestic freshwater fish cutting and descaling technology and equipment,fish body descratation and dirty processing efficiency is low,labor intensity is high,it is difficult to meet the needs of freshwater fish factory processing,etc.,this paper takes silver carp as the research object,on the basis of the detection and research of the physical characteristics of the fish body,the theoretical analysis,module design,finite element simulation and other methods are used to carry out the structural design of the clip-on fish cutting machine,and carry out relevant test verification.The specific research content is as follows:(1)Carried out research on the detection of physical characteristics of silver carp.The universal material testing machine is used to test the elastic modulus of the fish body and the maximum shear force of the fish body.The experimental results show that within the range of elastic variation,The average elastic modulus on the straight line on the back of the silver carp is 1.58 MPa,the average maximum pressure that can be tolerated is 38.32 N,and the average maximum compressive stress is 5.52 MPa;the average elastic modulus on the central straight line is 2.03 MPa,and the average maximum pressure can be 53.96 N and the average maximum compressive stress is 3.89 MPa;the average elastic modulus on the abdominal straight line is 1.16 MPa,which can withstand the average maximum pressure of 33.67 N and the average maximum compressive stress is 2.67 MPa;and the maximum shear force at the skull and spine of the silver carp is about 223.6 N.(2)Determine the factors affecting the effect of silver carp cutting and destainment through bench test.Taking the sensory evaluation score of the fish body cutting effect and the desquailing effect as the evaluation index,the factors affecting the fish body dissection and descaling effect were studied by building the silver carp dissection and descaling test bench,and the optimal combination of influencing factors was explored through orthogonal testing,and the test results showed that in the process of cutting and descaling,the spacing of the belt,the height of the cutterhead cutting,and the speed of the turning of the cutterhead had a significant impact on the processing effect of the fish body;the optimal working parameter combination was 40 mm in the spacing of the sandwich belt and 135 mm in the cutterhead cutting height.The cutterhead speed is 1100r/min.(3)Carried out the overall structural design study of the fish cutting machine.Using modular design methods,the overall structure of the fish cutter is divided into rack module,clamping system module,cutting and destaining module,etc.,and solidworks software is used to model the three-dimensional solid of each module and assemble it;at the same time,the simulation analysis of the key components of the fish cutter is carried out to verify the rationality of the structural design of the key components.(4)Carry out the design of the control system of the fish cutting machine.With PLC as the center,the control system of the fish cutting machine is designed,the control program is written using Mitsubishi GX works2 software,and the human-computer interaction interface of the machine is designed to realize the automatic control and monitoring of the machine operation process.
