AI Technical Summary

Technical Problem

When existing eel processing machines process larger fish, fish bones are easily offset, resulting in inaccurate deboning and the bones cannot be effectively positioned between the figure-eel-shaped deboning knives.

Method used

By adjusting the bolts and the adjusting washers, the deformation fulcrum position of the feed tube is changed, the deformation amount of the main board is adjusted, the fish bones are ensured to be located between the figure-eight boning knives, and the adjusting washers are used to reduce wear and provide elastic buffering.

Benefits of technology

It achieves adaptive compaction of fish bodies in different weight ranges, avoids the situation where the fish meat is crushed or not compacted tightly, ensures the accurate removal of fish bones, and extends the service life of the equipment.

Abstract

The present invention relates to a cutting and deboning adjustment mechanism for an eel processing machine, belonging to the technical field of eel processing machinery. The mechanism comprises a feeding gear disc, a pressing gear disc, a cutting knife and a deboning knife. A pressing gear disc is installed on a frame via a short shaft, and the pressing gear disc is meshed with a transmission gear of a power motor. A feed pipe is installed on the frame between the feeding gear discs via a frame cross bar A and a frame cross bar B, and one end of the feed pipe is fixedly connected to the frame cross bar A. An adjusting bolt is threadedly installed on the frame cross bar B, and an adjusting gasket is provided at the bottom of the feed pipe corresponding to the adjusting bolt, and the adjusting gasket is in contact with the adjusting bolt. The deformation degree of the feed pipe is adjusted in conjunction with the adjusting bolt to achieve accurate removal of fish bones. The cutting and deboning adjustment mechanism can adapt to fish bodies of different weight ranges by cooperating with the adjusting gasket and the adjusting bolt, and can effectively ensure that the fish bones are located between the deboning knives arranged in an eight-shaped shape during operation, thereby achieving accurate deboning.

Claims

1. A cutting and deboning adjustment mechanism for an eel processing machine, comprising a feeding toothed disc (2), a pressing toothed disc (3), a cutting knife (4) and a deboning knife (5), a frame (1) being provided with a pressing toothed disc (3) via a short shaft (7), the pressing toothed disc (3) being meshed with a transmission gear (11) of a power motor (10), a deboning knife (5) being provided in an eight-shaped pattern on the frame (1) below the pressing toothed disc (3), a feeding toothed disc (2) being symmetrically provided horizontally on the frame (1) on one side of the deboning knife (5), a cutting knife (4) being provided on the frame (1) below the feeding toothed disc (2), and characterized in that: A feed pipe is installed on the frame (1) between the feed gear discs (2) through the frame crossbar A (19) and the frame crossbar B (20), and the feed pipe includes a main board (31), a half side plate (32), a top plate (52) and a connecting pipe. One end of the main board (31) is fixedly installed on the frame crossbar A (19), a top plate (52) is provided above the main board (31), and a half side plate (32) is symmetrically fixed between the main board (31) and the top plate (52). A connecting pipe is provided on the main board (31) between the half side plates (32), and one end of the connecting pipe extends to the outside of the main board (31) and the top plate (52); one end of the feed pipe is fixedly connected to the frame crossbar A (19); an adjusting bolt (40) is threadedly installed on the frame crossbar B (20), corresponding to the adjusting bolt (4 0) is provided with an adjusting gasket (41) at the bottom of the feed pipe. The adjusting gasket (41) is provided between the adjusting bolt (40) and the feed pipe, which can reduce the wear caused by the direct hard contact between the adjusting bolt (40) and the feed pipe, thereby extending its service life. The elasticity of the adjusting gasket (41) itself can give the main board (31) a certain buffer stroke, so as to utilize the elastic force of the adjusting gasket (41) itself to assist the main board (31) to perform a certain elastic recovery, so as to reduce the problem that the elastic deformation of the main board (31) exceeds its own elastic deformation range and the main board (31) cannot press the fish body in the later stage. The adjusting gasket (41) is in contact with the adjusting bolt (40) to cooperate with the adjusting bolt (40) to adjust the deformation of the feed pipe, thereby realizing the accurate removal of fish bones.

2. The eel cutting and deboning adjustment mechanism of the eel processing machine according to claim 1, characterized in that: One end of the top plate (52) is provided with a recess (33) for forming a recess space for the feeding toothed disc (2), and a reinforcing rib (34) is provided on the top plate (52) on one side of the recess (33) to prevent the top plate (52) from deforming.

3. The eel cutting and deboning adjustment mechanism of the eel processing machine according to claim 1, characterized in that: A knife groove (35) for forming a clearance space for the cutting knife (4) is provided on the main board (31) on one side of the connecting pipe.

4. The cutting and deboning adjustment mechanism of the eel processing machine according to claim 3, characterized in that: A bolt hole (36) is provided on the main board (31) on one side of the said yielding knife groove (35), and yielding recesses (39) for forming a yielding space for the boning knife (5) are provided on the main board (31) on both sides of the bolt hole (36).

5. The cutting and deboning adjustment mechanism of the eel processing machine according to claim 1, characterized in that: A bone stripping block (42) is mounted on the frame (1) corresponding to the feed pipe. The bone stripping block (42) is a block-shaped body. A protrusion (43) is provided on the bone stripping block (42). The protrusion (43) is in an arc shape.
