Mounting structure of scaling knife of fish killing machine

Abstract

The invention discloses a mounting mechanism of a scaling knife of a fish killing machine, belongs to the technical field of fish processing equipment, and solves the problems that existing return springs are uneven in stress, prone to abrasion and breakage and short in service life. The mounting mechanism comprises two fixing discs which are oppositely arranged, a mounting hole penetrating fixingdiscs in the axial direction is formed in the center of the two fixing discs, at least one scaling combination distributed on the axial peripheral side is arranged between the two fixing discs, and each scaling combination comprises a return spring which is arranged between the two fixing discs in a connection mode and extends in the axial direction, a fixed rotating shaft, scaling blades, a movable shaft, a limiting column and a spring pressing plate. By means of the structure, breakage caused by back-and-forth friction between the return spring and the movable shaft can be avoided, the stress points of the return spring are uniform, the structural stability is improved, the service life is prolonged, state recovery of the scaling blades after each action can be quicker, and the use performance of the fish killing machine using the scaling knife is further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fish processing equipment, and specifically relates to the field of fish killing machines, more precisely, it relates to an installation mechanism for fish scale knives of fish killing machines. Background technique [0002] The fish killing machines currently on the market mainly complete the two steps of descaling and dissection of the fish. During the descaling process, it is required to remove the main fish scales on both sides of the fish body, even the fish scales on the abdomen and back. The patent document with the announcement number CN207505857U is disclosed "A descaling kit, descaling mechanism and fish killing machine", its descaling blade 3 is a scimitar-shaped structure, its outer side is provided with descaling serrations from the pointed head to the tail, and the inside and outside sides of the tail are respectively There is a first bayonet that cooperates with the first limiting plate 5 a...
