In the natural state of the return spring 20, the limit bayonet 22b abuts against the limit column (as shown in fig. 4, which is the natural state of the return spring), the tail part of the movable shaft 23 at the end far away from the end joint is positioned in the reserved hole 25a or is closest to the reserved hole 25a, the return spring 20 is in the normal extension state, when the scaling blade 22 rotates under stress, the movable shaft 23 passes through the reserved hole 25a, the return spring 20 is compressed (as shown in fig. 3, which is the compression state of the return spring), when the return spring 20 reaches the compression limit, the return spring 20 is not compressed any more, in the process that the scaling blade 22 is continuously extruded by the fish, the return spring 20 is repeatedly compressed, the reaction force for extruding the surface of the fish can be adjusted according to the size of the fish, not only can a good scaling effect be ensured, but also the fish can be prevented from being excessively extruded by the scaling blade 22 due to the excessive pressure, ensuring good taste of fish.

Preferably, in order to ensure that the installation positions of the five descaling blades 22 on each fixed rotating shaft 21 are uniformly distributed, positioning shaft sleeves 26 which are sleeved on the fixed rotating shaft 21 are further arranged between two adjacent descaling blades 22 on the same fixed rotating shaft 21 and between the descaling blades 22 and the adjacent fixed disks 1, the positioning shaft sleeves 26 are used for limiting, the descaling blades 22 are installed in a spaced mode, the descaling blades 22 are prevented from moving along the circumferential direction of the fixed rotating shaft 21 during descaling, and the descaling blades 22 only rotate.

The descaler assemblies 2 are uniformly distributed between the two fixed disks 1 on the axial peripheral side.

The two groups of the descaling assemblies 2 are distributed in a staggered mode on the circumferential position of the mounting hole 11, the descaling assemblies 2 are installed in a surrounding mode around the position, 180 degrees away from the position of the mounting hole 11, as shown in fig. 2, basically two movable shafts 23 are in a parallel state, two fixed rotating shafts 21 and two limiting columns 24 penetrate through two fixed disks 1 and are located on the head side and the tail side between the two movable shafts 23, and two descaling blades 22 are compressed anticlockwise during rotation and rotate around the fixed rotating shafts 21.

When the two descaling rotating shafts rotate simultaneously, the descaling suites on the two sides of the fish body continuously rotate and remove scales on the fish body through the descaling blades 22, and the descaling effect is good. The way of assembling the plurality of groups is disclosed in detail in patent document No. CN207505857U, and will not be described in detail here.

The working principle of the descaling mechanism is as follows: firstly, in a natural state, the return spring 20 is in a normal state, the limiting bayonet 22b is abutted to the limiting column 24 through a reaction, and when the descaling blade 22 rotates to act on the surface of a fish body to remove fish scales, the descaling blade 22 continues to compress the return spring 20 under the action of the reaction force, so that the descaling blade 22 continues to rotate through the fish body after removing the fish scales. The arrangement of the spring pressing plate 25 and the movable shaft 23 can limit the scale removing blade 22 to excessively compress the return spring 20, and avoid the fish meat from being hurt due to excessive reaction force of the excessively compressed return spring 20 on the scale removing blade 22.

The installation mechanism of the fish scale knife of the fish killing machine is described in detail above. The description of the specific embodiments is only intended to facilitate an understanding of the method of the invention and its core ideas.
