Abstract

The present invention relates to a protective guide mechanism for an eel and loach dissecting and deboning machine, belonging to the technical field of aquatic product processing machinery. The mechanism comprises a deflection correction protective plate and a guide block. The deflection correction protective plates are symmetrically fixedly mounted on either side of the guide block to cooperate with the guide block to clamp and guide the advancing fish, preventing the fish from deviating and moving forward in a straight line. This mechanism guides the fish through the abdominal dissection process from head to tail. This protective guide mechanism effectively prevents the eel or loach from twisting during the slaughtering process, causing the incision to deviate. This ensures effective deboning of the fish and allows the fish chamber to be fully opened.

Description

Technical Field

[0001] The invention relates to a protective guide mechanism of an eel cutting and deboning machine, belonging to the technical field of aquatic product processing machinery. Background Art

[0002] With the development of the aquaculture industry, loaches and yellow eels have entered the era of factory farming. Consequently, a large number of deep-processed, ready-to-eat eel and loach foods have been launched on the market. While meeting people's daily needs, these foods have also achieved good economic benefits. The production process of these deep-processed, ready-to-eat eels and loaches requires first slaughtering and deboning the eels and loaches using a deboning slaughtering machine. The deboning slaughtering machine operates by feeding live eels and loaches from a feed box through a discharge pipe onto a slaughtering conveyor plate. Rotating slaughtering and deboning cutters then slaughter and debone the eels and loaches. Since the eels and loaches being slaughtered are all alive, they will twist their bodies desperately under the emergency reaction during the slaughtering process, which can easily cause the slaughtering incision to deviate. Once it deviates, the fish chamber will not be fully opened, and it will directly affect the effect of removing the fish bones, and even cause the fish bones to not be completely removed. Summary of the Invention

[0003] The purpose of the present invention is to provide a protective guide mechanism for an eel and loach dissecting and deboning machine that can effectively prevent the eels and loaches from deviating from the slaughtering incision due to twisting of their bodies during the slaughtering process, thereby ensuring the effect of removing fish bones and allowing the fish chamber to be fully opened.

[0004] The technical solution of the present invention is:

[0005] A protective guide mechanism for an eel cutting and deboning machine, which consists of a correction protective plate and a guide block; its characteristics are: the correction protective plates are symmetrically fixedly installed on both sides of the guide block to cooperate with the guide block to clamp and guide the moving fish body, so that the fish body moves forward in a straight line to prevent deviation, thereby guiding the fish body to complete the abdominal cutting process from head to tail.

[0006] The correction protection plate is in the shape of a long strip, and the front end of the correction protection plate is conical. The end face on one side of the front end of the correction protection plate is respectively provided with a clearance groove for the conveying roller to extend downward; the correction protection plate below the clearance groove is set in a slope; and the top of the correction protection plate above the clearance groove is provided with a mounting hole.

[0007] There is a slope transition between the recess and the front end of the deviation-correcting protective plate.

[0008] The guide block is a rectangular parallelepiped with a variable diameter, and the front end of the guide block is tapered; a give-way inclined groove is provided on both sides of the tail end of the guide block, and a give-way groove is provided in the middle of the tapered part of the front end of the guide block; anti-slip ratchets are respectively provided on the guide blocks on both sides of the give-way groove.

[0009] The top of the guide block at the rear end of the clearance slot is provided with a plurality of fixing holes for assembling the guide block in an interval shape.

[0010] The beneficial effects of the present invention compared with the prior art are:

[0011] The protective guide mechanism of the eel cutting and deboning machine clamps and guides the fish body through the correction protective plate, so that the fish body moves forward in a straight line to prevent the slaughtering incision from deviating, thereby guiding the fish body to complete the abdominal dissection process from the head to the tail; the anti-slip ratchet of the guide block can effectively prevent the fish body from slipping and retreating during the straight-line forward movement, further ensuring the smooth transportation of the fish body. At the same time, the tapered guide block pre-opens the fish chamber to facilitate the smooth deboning operation in the subsequent sequence. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] As attached Figure 1-4 shown

[0018] The protective guide mechanism of this eel cutting and deboning machine consists of a deflection-correcting guard plate 1 and a guide block 2. The deflection-correcting guard plates 1 are symmetrically fixed to either side of the guide block 2. When the protective guide mechanism is installed, the guide block 2 is fixed to the frame 18. The guide block 2 is a rectangular parallelepiped with a tapered front end, allowing it to enter the fish chamber more smoothly. A tapered chute 3 is provided on either side of the guide block 2's rear end. This chute 3 is used to make way for a deboning knife 4, providing a working angle for the knife 4 and ensuring that the guide block 2 can simultaneously open the fish chamber and perform deboning operations.

[0019] Among them, horizontal conveying wheels 17 are symmetrically arranged on the frames 18 on both sides of the front end of the guide block 2, and boning shafts 5 are symmetrically arranged on the frames 18 below the guide block 2. Boning knives 4 are installed on the boning shafts 5, and the two boning knives 4 are symmetrically arranged in an eight-shaped shape; a boning motor 6 is fixedly installed on the frame 18 corresponding to the boning shaft 5, and the boning motor 6 is connected to the boning shaft 5. When working, the boning motor 6 drives the boning shaft 5 to rotate, and the boning shaft 5 drives the boning knife 4 to rotate, thereby performing the boning operation.

[0020] A clearance groove 7 is provided in the middle part of the tapered portion at the front end of the guide block 2. The clearance groove 7 is used to make way for the cutting knife 8 so that the cutting knife 8 can extend and ensure that the guide block 2 can enter the fish chamber after the eel or loach is opened.

[0021] A disc-shaped cutting knife 8 is installed on the frame 18 corresponding to the lower portion of the clearance slot 7 through the cutting shaft 9; a cutting motor is installed on the frame 18 corresponding to the cutting shaft 9, and the cutting motor is connected to the cutting shaft 9. When working, the cutting motor drives the cutting knife 8 to rotate through the cutting shaft 9.

[0022] The guide blocks 2 on both sides of the clearance groove 7 are respectively provided with anti-skid ratchets 10 to prevent the fish body from slipping at the tapered portion at the front end during operation.

[0023] The top of the guide block 2 at the rear end of the clearance slot 7 is provided with a plurality of fixing holes 11 for assembling the guide block 2 in an interval shape. By installing different fixing holes 11, the distance between the guide block 2 and the conveying roller 13 can be adjusted, thereby adapting to batches of eels or loaches of different specifications and sizes.

[0024] The correcting protection plates 1 are symmetrically fixedly installed on the frames 18 on both sides of the guide block 2. The correcting protection plates 1 are long strips, and the front end of the correcting protection plates 1 is conical. The end faces of the front end of the correcting protection plates 1 are respectively provided with clearance grooves 12 for the conveying rollers 13 to extend downward, so as to cooperate with the guide blocks 2 to clamp and guide the moving fish body, so that the fish body can move forward in a straight line to prevent deviation, thereby guiding the fish body to complete the abdominal dissection process from the head to the tail.

[0025] A conveying roller 13 is installed on the frame 18 above the guide block 2 through the conveying shaft 14; a conveying motor is fixedly installed on the frame 18 on one side of the conveying roller 13, and the conveying motor is connected to the conveying shaft 14 of the conveying roller 13 through a transmission shaft. When working, the conveying motor drives the conveying roller 13 to rotate through the conveying shaft 14.

[0026] The correcting guard plate 1 below the yielding groove 12 is arranged in a sloped surface, so that the space between the sloped correcting guard plate 1 and the guide block 2 is effectively increased to accommodate the eel or loach, thereby keeping the fish chamber of the eel or loach open after being cut open.

[0027] A mounting hole 15 is provided on the top of the deflection correction protection plate 1 above the clearance groove 12 for fixing the deflection correction protection plate 1 on the frame 18 .

[0028] There is a slope transition between the clearance groove 12 and the front end of the correcting protective plate 1 to guide the eel or loach to move to the middle position between the two correcting protective plates 1, thereby playing a role in pre-correction and guidance of the fish head.

[0029] Taking eels as an example, when the protective guide mechanism is working, the eels to be slaughtered and deboned slide out from the outlet of the feed pipe 16 of the eel cutting and deboning machine to between the two horizontal conveying wheels 17 of the eel cutting and deboning machine, and continue to be pushed forward by the two horizontal conveying wheels 17. In the process of the eel being pushed, the cutting motor drives the cutting knife 8 to rotate, and the cutting knife 8 cuts the eel's abdomen and enters the fish chamber. At this time, the eel continues to move forward under the action of the horizontal conveying wheel 17. When the eel's head moves between the conveying roller 13 and the guide block 2, the rotating conveying roller 13 cooperates with the guide block 2 to clamp the eel's head and drive the eel to continue moving forward along the guide block 2. During this process, the conveying roller 13 generates a downward pressure on the eel. This pressure not only drives the eel forward along the guide block 2, but also ensures that the eel contacts the cutting knife 8 while moving forward, thereby completing the cutting of the eel's abdomen.

[0030] As the conveyor roller 13 exerts downward pressure on the eel, it cooperates with the guide block 2 to clamp the eel's head and drive the eel forward along the guide block 2. At the beginning of the process of the cutter 8 completing the sectioning of the eel's belly, the guide block 2 smoothly enters the eel's belly (fish chamber), thereby wrapping the eel's fish chamber around the guide block 2, which in turn supports the eel's belly. As the conveyor roller 13 rotates, the corrective guard plate 1 cooperates with the guide block 2 to limit the eel's belly, thereby preventing the eel from deviating during the sectioning.

[0031] When the conveying roller 13 cooperates with the guide block 2 to clamp and push the eel forward to the position of the boning knife 4, the conveying roller 13 exerts a downward pressure on the eel. At this time, the eel spine whose abdomen has been cut (opened) is located between the boning knives 4, and the eel meat stretched by the guide block 2 is located on the outer surface of the boning knife 4; the edges of the two boning knives 4 contact above the eel spine, and as the boning knife 4 rotates and the eel moves forward along the guide block 2, the boning knife 4 that enters the eel's abdominal cavity peels off the spine from the fish meat, thereby realizing the precise removal of the eel spine.

[0032] The protective guide mechanism can effectively prevent the eels and loaches from twisting their bodies during the slaughtering process, causing the slaughtering incision to deviate; and can fully open the fish chamber, thereby ensuring the removal of fish bones.
