The descaling ring 23 is arranged so that: so that in the process that the scaled fish 28 passes through the inside of the fish guide groove 2, when the scale removing ring 23 is extruded by the scaled fish 28, the scale removing ring 23 can be compressed and contracted, so that the scale removing patches 24 on the surface of the scale removing ring can be attached and connected with the surface of the scaled fish 28 with certain elasticity, and the purpose of scraping off the scales can be achieved through the scale removing teeth on the scale removing patches 24 in the rotating process of the scale removing ring 23.
The descaling rings 23 on the rolling shaft A19 and the descaling rings 23 on the rolling shaft B20 are arranged in a staggered manner; the descaling rings 23 on the rolling axis C21 are arranged in a staggered manner with respect to the descaling rings 23 on the rolling axis D22 (see the description and the attached figure 3). In addition, the projections of the descaling rings 23 on the rolling shaft A19 and the projections of the descaling rings 23 on the rolling shaft B20 on the vertical projection plane have mutually overlapped parts; the projections of the descaling rings 23 on the rolling axis C21 and the descaling rings 23 on the rolling axis D22 on the vertical projection plane are overlapped; the descaling ring 23 is arranged so that: firstly, the descaling rings 23 can be staggered to act on the surface of the scaled fish 28 so as to avoid the problem that the fish skin is damaged when the scaled fish 28 is stressed intensively; secondly, the descaling rings 23 on the rolling shaft A19 and the rolling shaft B20 can remove fish scales at one time; the descaling rings 23 on the rolling shaft C21 and the rolling shaft D22 can remove fish scales again, so that the aim of improving the scale removing effect is fulfilled; thirdly, because the descaling rings 23 have mutually overlapped parts in the projection, the descaling rings 23 can avoid the problem of 'cleaning missing' in the process of cleaning the fish scales.
The rolling shaft B20 in the descaler A6 is connected with the descaler motor 16 through a driving chain A17; the upper end of the rolling shaft B20 is connected with the upper end of the rolling shaft D22 through a reversing chain 31 (see the description and the attached figure 6). When the descaling motor 16 is connected with the descaling motor, the rolling shaft B20 is driven by the descaling motor 16 through the transmission chain A17 to rotate anticlockwise, and the rolling shaft B20 can drive the rolling shaft A19 to rotate clockwise through the transmission gear pair 25; meanwhile, the rolling shaft B20 drives the rolling shaft D22 to rotate anticlockwise through the reversing chain 31; the rolling shaft D22 drives the rolling shaft C21 to rotate clockwise through the transmission gear pair 25. The purpose of the design is as follows: firstly, the rotation directions of the rolling shaft C21 and the rolling shaft D22 are opposite, and the rotation directions of the rolling shaft A19 and the rolling shaft B20 are opposite; therefore, in the working process of the fish scale remover, the rolling shaft C21, the rolling shaft D22, the rolling shaft A19 and the rolling shaft B20 can act on the fish body in a positive-negative mode, so that the purposes of balancing the stress of the fish, slowly penetrating through the side of the scale remover A6 and effectively removing the scales are achieved; and the problem of the current descaling equipment during operation, because the scaling roller turns to unanimously, lead to its working process rapid will have the output of scale fish from between the scaling roller, the effect of descaling that causes is poor is further solved. Secondly, the rolling shaft D22 can rotate anticlockwise and act on the scaled fish 28, so that when the rolling shaft C21 is in contact with the scaled fish 28 during working, and the rolling shaft D22 acts anticlockwise on the scaled fish 28, an acceleration force can be applied to the scaled fish 28, so that the scaled fish can move in an accelerated manner along the fish guide groove 2, and the purpose of unhooking the scaled fish 28 from the fish hook 15 in the process of accelerated movement is achieved.
The rolling shaft A19 of the descaler B7 is connected with the descaler motor 16 through a transmission chain B18; the upper end of the rolling shaft A19 is connected with the upper end of the rolling shaft C21 through a reversing chain 31 (see the description and the attached figure 6). When the descaling motor 16 is connected with the descaling motor, the rolling shaft A19 is driven by the descaling motor 16 through the transmission chain B18 to rotate anticlockwise, and the rolling shaft A19 can drive the rolling shaft B20 to rotate clockwise through the transmission gear pair 25; meanwhile, the rolling shaft A19 drives the rolling shaft C21 to rotate anticlockwise through the reversing chain 31; the rolling shaft C21 drives the rolling shaft D22 to rotate clockwise through the transmission gear pair 25. The purpose of the design is as follows: firstly, the rotation directions of the rolling shaft C21 and the rolling shaft D22 are opposite, and the rotation directions of the rolling shaft A19 and the rolling shaft B20 are opposite; therefore, in the working process of the fish scale remover, the rolling shaft C21, the rolling shaft D22, the rolling shaft A19 and the rolling shaft B20 can act on the fish body in a positive-negative mode, so that the purposes of balancing the stress of the fish, slowly penetrating through the side of the scale remover B7 and effectively removing the scales are achieved. Secondly, the rolling shaft D22 can rotate clockwise to act on the scaled fish 28, so that when the rolling shaft C21 is out of contact with the scaled fish 28 in working, and the rolling shaft D22 acts clockwise on the scaled fish 28, an acceleration force can be applied to the scaled fish 28, so that the scaled fish can move in an accelerated manner along the fish guide groove 2, and the purpose of unhooking the scaled fish 28 from the fish hook 15 in the process of accelerated movement is achieved.
A laparotomy disc knife 8 is arranged on the frame 1 at one side of the descaler B7 through a laparotomy motor 10; one side of the laparotomy disc knife 8 is provided with a dirt removing rolling brush 9 through a transmission shaft 11; the transmission shaft 11 and the laparotomy motor 10 are connected with each other through a transmission belt 13 (see the description and the attached figure 1). The laparotomy motor 10 can drive the laparotomy disc knife 8 to synchronously rotate in the rotating process, and simultaneously, the laparotomy disc knife can drive the transmission shaft 11 and the dirty removing rolling brush 9 to synchronously rotate through the transmission belt 13.
The dirt removing rolling brush 9 and the laparotomy disc knife 8 penetrate through the fish guide groove 2 from the bottom and then extend into the fish guide groove 2; a spreading block 12 in a nose wing shape is arranged on the fish guiding groove 2 between the laparotomy tray knife 8 and the dirty removing rolling brush 9 (see the attached figure 5 in the specification); the deployment block 12 is provided for the purpose of: when the scaled fish 28 after being split is passed through the upper part of the expansion block 12 in operation, the expansion block 12 can expand the belly skin of the scaled fish 28 along the cutting edge, so that the internal organs of the scaled fish 28 can be conveniently removed by the rotary dirt removing rolling brush 9.
The frame 1 above the laparotomy disc knife 8 and the dirty removing rolling brush 9 is respectively provided with an elastic limiting wheel 29 (see the attached figures 2 and 5 in the specification) made of flexible materials, and the lower part of the elastic limiting wheel 29 extends to the inside of the fish guiding groove 2; the circumferential surface of the elastic limiting wheel 29 is provided with a limiting ring groove (not shown in the specification). The purpose of thus arranging the elastic limiting wheel 29 is to: so that the laparotomy tray knife 8 and the dirt removing rolling brush 9 act on the scaly fish 28 and drive the scaly fish 28 to act, the elastic limiting wheel 29 can apply certain pressure to the scaly fish 28, so that the scaly fish 28 can be in close contact with the laparotomy tray knife 8 and the dirt removing rolling brush 9, and the laparotomy and dirt removing work of the scaly fish 28 can be smoothly completed.
When the pretreatment device for processing the scaled fish works, the driving chain A3, the driving chain B4, the laparotomy motor 10 and the descaling motor 16 are started in sequence; when the descaling motor 16 works, the descaling device A6 and the descaling device B7 are driven to synchronously rotate; when the laparotomy motor 10 rotates, the laparotomy disc knife 8 and the dirty removing rolling brush 9 are driven to synchronously rotate.
After the preparation is completed, the scaled fish 28 is manually placed in the fish guide groove 2 at the inlet end of the fish guide groove 2, and then the gills of the scaled fish 28 are hung on the fishhooks 15 of the driving chain A3, so that the moving driving chain A3 can drive the scaled fish 28 to pass through the descalers a6 along the fish guide groove 2 through the fishhooks 15. During the process that the scaled fish 28 passes through the scaler A6, the rolling shaft A19, the rolling shaft B20, the rolling shaft C21 and the rolling shaft D22 which rotate in the scaler A6 act on the side surface of the scaled fish 28 through the descaling ring 23 and the descaling patches 24, so that the descaling patches 24 can complete the descaling work of the scaled fish 28 through the descaling teeth of the descaling patches 24.
In the process that the descaling device A6 finishes removing scales from the side of the scaly fish 28, the rolling shaft C21, the rolling shaft D22 and the rolling shaft A19 and the rolling shaft B20 act on the fish body in a positive and negative mode, so that the scales can slowly penetrate through the descaling device A6, and the purpose of effectively removing the scales is achieved.
When the descaler A6 finishes the descaling operation of the scaled fish 28, when the rolling shaft C21 is out of contact with the scaled fish 28 and the rolling shaft D22 acts on the scaled fish 28 counterclockwise, the rolling shaft D22 can apply an accelerating force to the scaled fish 28 through the descaling patches 24, so that the scaled fish can move in an accelerating manner along the fish guide groove 2, and the purpose of unhooking the scaled fish 28 from the fish hook 15 of the driving chain A3 in the accelerating movement process is achieved.
When the scaled fish 28 having one side descaled is unhooked from the fish hook 15, the scaled fish 28 moves downward along the curved portion under the influence of inertia and its own weight. At this time, because the upper end of the curved arc part is larger than the lower end, when the scaly fish 28 moves to the output end of the curved arc part, the scaly fish 28 will be clamped at the inlet end of the transverse part of the fish guiding groove 2 in an inward-curved shape (see the attached figure 8 in the specification); the moving drive chain B4 will carry the gill of the scaled fish 28 along the fish guide 2 through the descaler B7 by the hook 15.
During the process that the scaled fish 28 passes through the descaler B7, the rolling axis A19, the rolling axis B20, the rolling axis C21 and the rolling axis D22 which rotate in the middle of the descaler B7 act on the other side surface of the scaled fish 28 through the descaling ring 23 and the descaling patch 24, so that the descaling patch 24 can complete the descaling operation of the other side surface of the scaled fish 28 through the own descaling teeth.
In the process that the descaler B7 finishes removing scales from the side of the scaly fish 28, the rolling shaft C21, the rolling shaft D22, the rolling shaft A19 and the rolling shaft B20 act on the fish body in a positive and negative mode, so that the scales can slowly penetrate through the side of the descaler A6, and the purpose of effectively removing the scales is achieved.
When the descaler B7 finishes the descaling operation of the scaled fish 28, when the rolling shaft C21 is out of contact with the scaled fish 28 and the rolling shaft D22 acts on the scaled fish 28 clockwise, the rolling shaft D22 can apply an accelerating force to the scaled fish 28 through the descaling patch 24, so that the scaled fish can move along the fish guide groove 2 in an accelerating manner, and the purpose of unhooking the scaled fish 28 from the driving chain B4 of the driving chain A3 in the accelerating movement process is achieved.
The scaly fish 28 which is descaled later continues to move forward under the action of inertia, and when the scaly fish is contacted with the rotary laparotomy tray knife 8, the laparotomy tray knife 8 completes the laparotomy of the scaly fish 28 under the cooperation of the elastic limiting wheel 29 and continues to push the scaly fish to move forward. When the scaled fish 28 completes the laparotomy and passes through the upper part of the expansion block 12, the expansion block 12 can expand the belly skin of the scaled fish 28 along the cutting edge.
When the scaly fish 28 with the spread belly is contacted with the rotary dirt removing rolling brush 9, the rotary dirt removing rolling brush 9 removes the viscera of the fish through the spread belly, and drives the scaly fish 28 to move forwards continuously; when the scaly fish 28 with internal organs removed enters the fish storage barrel 5 along the fish guide groove 2 under the action of inertia and gravity, the pretreatment device for processing the scaly fish completely finishes the operations of scaling, laparotomy and internal organs removal of the scaly fish.
When the pretreatment device works, the scaly fish 28 is required to be clamped at the arc part of the fish guide groove 2 in the process of passing through the fish guide groove, and the pretreatment device can normally work, so that the pretreatment device can only complete the treatment work of the scaly fish 28 with similar specification and size, and cannot complete the treatment work if the scaly fish is too large; therefore, before the pretreatment device is used for treatment, scaly fishes to be treated need to be screened, and the working requirement of the pretreatment device can be met only by removing the unsuitable scaly fishes.
The pretreatment device for processing the scaly fish has compact structure and ingenious design; not only adopts the structural design of single-side descaling; in addition, in the process of scaling the fish by the descaler, each rolling shaft in the descaler is in a positive reaction on the fish body, so that the purposes of balancing the stress of the fish, slowly penetrating through one side of the descaler and effectively removing the scales are achieved, the problem of poor descaling effect existing in the conventional fish processing device is solved, and the use requirements of enterprises for production and processing are met.
