Description

Technical field:

[0001] The invention belongs to the category of aquatic product processing technology machines and is an electric yellow eel deboning machine. Background technology:

[0002] According to market research and patent searches, there is currently no patented processing technology that can remove bones from live yellow eels and separate the meat from bones to achieve a high net meat rate; similar patents that have been approved, as well as my patent No. 3515273 approved in 2019, have a strip of spinal meat remaining at the top of the spine that is the same size as the gap between the double-gear cutting blades and is connected to the spine below. This has to be separated from the spine manually, otherwise it will be wasted. The only way to achieve the highest net meat rate is to use a manual unpowered cleaver and cut off the spine close to the bone. Summary of the invention:

[0003] In order to meet the market demand, through the anatomical observation and analysis of the live yellow eel, the fish body is centered on the fish spine from head to tail, and the fish body can be divided into two parts; the upper part is structured as the upper back meat wrapped around the spine, and the bottom of the spine ends at the bottom of the middle upper part of the fish's abdominal cavity. Because the fish spine has no rib bones branching downward on the left and right sides of its chest and abdomen, the lower part of the fish body is naturally formed as boneless soft belly meat, in a semi-cavity state, and its contents are only tied to the fish's intestines and stomach. In view of the above conditions, a new fish body processing machine solution was redesigned: 1. Processing method; 2. Innovative electric tool; 3; Fish body position control; 4. Balanced control of fish bodies of different thicknesses; 5. Combined use of the four technologies in my patent No. 3515273 approved in 2019.

[0004] 1. Processing method: Since the fish body is centered on the spine from head to tail, and the spine is in the center of the fish body, the most effective way to debone is to first use an electric circular single blade to vertically cut the fish head and the fish back meat to expose the top of the spine, and then use a new electric tool: a deformed composite spine separation knife gear, to make a deep incision across the spine, and use the spine as a guide to make the eight-shaped left and right blades hug the spine tightly, and split from the back of the head to the tail.

[0005] 2. New electric tool: deformable composite spine separation knife gear: a thin, round steel sheet with flexible and elastic properties and a flat single-blade gear sheet with multiple rectangular teeth. After mechanical stamping, deformation and heat treatment, the blade part of the outer peripheral edge of the round single blade is deformed and bent into two angles to the left and right, about 5 degrees or less. The two single blades are combined into one, with a bending angle of about 10 degrees or less, and the composite blade is shaped like an eight, a single-blade double-edged knife gear; the knife gear is made to move along the spine that has been cut into a V-shaped incision, with the smallest blade fork, aligned with the top of the triangular spine, and accurately positioned astride the spine, so as to utilize the hardness and angle of the triangular spine of the fish body to stretch the flexible and elastic blade, use the spine as a guide, cut close to the spine, and overcome the purpose of residual spine meat in the spine belt.

[0006] 3. Control of fish body position: The outer guard wheel of the double-layer composite wheel for positioning and feeding fish cooperates with straightening and extrusion, and the pointed gear of the hook and fish feeding fish supporting is used to support the spine of the fish body to disperse the volume of the belly meat of the fish body. The part of the fish body to be cut is compressed and compacted purposefully, so that fish of different sizes are squeezed into an upright state when passing through this upper and lower gear combination, and the back meat can be accurately cut into a V shape to expose the top of the spine.

[0007] 4. Control method for balancing fish of different thicknesses: When live eels of different thicknesses enter the fish inlet of the machine, the elastic fish control pipe installed on the fish inlet is used to move the transition tongue plate up and down to pre-define the fish body and guide it into the fish hook and fish feeding top support sharp gear installed on the lower abdomen of the fish body. The spring force of the elastic top supporter forms a front and rear series of up and down fish control, balancing the thickness of the fish body, and cooperating with the knife gear to cut the entire stage.

[0008] 5. I combined and utilized the four technologies in my patent No. 3515273 approved in 2019, improved and renamed the four technologies in the original patent, and then combined them with the technologies to create a more complete patented technology for deboning yellow eel.

[0009] For example: (1) The technology still utilizes and retains the original patent

[0008] line... The hollow pipe for conveying fish bodies: the hollow pipe is connected to the fish collection box for killing at the top and the entrance of the eel deboning machine at the bottom. The hollow pipe for conveying fish bodies is equipped with a photoelectric control, a micro motor and a fish body booster gear kit. The micro motor booster gear starts working based on the light control signal detection feedback from the fish outlet...

[0010] For example: (2) The technology still uses and retains the main frame mechanism in the original patent

[0009] 2, ... the fish body enters the interior, passes through the fish body positioning and feeding double-layer wheel inner blade wheel, and the outer guard wheel is a set of two double-layer positioning and feeding blade gears, and its circular inner blade is evenly distributed with a number of small rectangular teeth .... Now it is still used and combined with this combination wheel, and after improvement, it is named: positioning and feeding fish double-layer composite wheel, changing the original double blade to a single blade;

[0011] For example: (3) The technology still utilizes and retains the detachable base mechanism in the original patent

[0010] 3, ... on which a sharp gear for hooking and sending fish is installed .... The sharp gear for hooking and sending fish in the original patent is still utilized, but after improvement, it is improved from the original single-pointed gear piece to a combination of three gear pieces symmetrically arranged in parallel with the gear transmission shaft as the center, and the long-pointed gear piece in the center is higher than the two fine-toothed gear pieces symmetrically installed on the left and right, and is named: the sharp gear for hooking and sending fish.

[0012] For example: (4) The technology still utilizes and retains the dual-speed technology in line

[0023] of the original patent: … the upper cutter mechanism runs at high speed, and the lower fish feeding gear runs at low speed, forming an upper and lower speed difference, so that the fish body passively accepts cutting while in a low-speed motion state…

[0013] The DC 12V safe voltage power supply is used to ensure a high net meat rate, taking into account the largest commercial fish specifications of yellow eels on the market, which are large numbers of medium-diameter fish. Also, because the thickness of yellow eels varies greatly: it is difficult to put eels below seven or eight millimeters on the machine, and it is inevitable that waste will occur if the thick fish of thirty or forty millimeters are killed on the same machine. Appropriate restrictions must be imposed on fish of different thicknesses to ensure that the clearance of each cutter gear and the internal and external dimensions of the supporting functional components are treated specifically. Only when they can be freely adjusted and refined, Only in this way can one machine be used to process eels of different sizes and thicknesses and remove bones; in terms of machine shape and volume, unnecessary complexity is overcome to make it convenient for the public, compact and practical: the machine is divided into three types for finalization: Type A: large and medium-coarse machines, taking into account large and medium-coarse volume fish; Type B: medium-fine machines, taking into account medium-coarse and thin volume fish; Type C: market professional machines taking into account large, medium and small volume fish, and Type C machines are necessarily large in size, complicated in technology, and have a large processing volume, etc. The present invention is implemented according to the following technical scheme:

[0014] Technical solution: It is divided into three major components: 1. Main frame components; 2. Main motor and semi-fixed mounting base plate; 3. Removable lifting base platform, etc. Its shape and structure are described as follows:

[0015] 1. Mainframe components: including: 1 left and right mainframe plates; 2 hollow pipes for conveying fish bodies and docking ports; 3 fixed transverse partitions and docking ports for fish inlet pipes; 4 elastic fish control pipes; 5 upper and lower movable transition tongue plates; 6 fish hooking and fish feeding top supporting sharp gears; 7 positioning fish feeding double-layer composite wheels; 8 deformable composite spine separation knife gears; 9 elastic top supporting devices; 10 anvil wheel assembly: including elastic guide rail components; 11 segmented blade wheels and blades; 12 bearings and bearing positioning movable mounting hole plates; 13 gear transmission shafts; 14 divided power motors; 15 removable notches.

[0016] 1 Left and right mainframe plates: Two rectangular, thick stainless steel plates or aluminum plates are used. Four holes are drilled on the outer edges of the four corners of the left and right mainframe plates to insert and fix the mainframe plates. Four mainframe fixing extension screws and nuts are used to fix them in parallel to form the mainframe skeleton of the whole machine. All the gears, tools, gear power sub-motors, transmission shafts, bearings, and bearing positioning movable mounting hole plates on the whole machine are assembled on the left and right rectangular mainframe plates of the whole machine. In order to facilitate the whole machine For assembly and maintenance, as well as replacement and disassembly of individual gears and parts, a notch with the same width as the outer diameter of the bearing is sawed from the installation and fixing positioning points of the upper and lower gear transmission shafts on the rectangular left and right main frame plates to the upper and lower outermost edges in the vertical directions on the left and right frame plates, and then the bearing positioning movable mounting hole plate is used to correspondingly disassemble, overlap and fix the gear transmission shafts and bearings; a notch is also sawed obliquely at the rear end of the left and right rectangular main frame plates, and an anvil wheel elastic guide rail component is installed.

[0017] 2. Hollow pipe for conveying fish and docking port: This component can be omitted on the A and B models of the machine. Instead, a simple plastic fish basket and the hollow plastic pipe on it can be used. The fish can be released by manually opening and closing the valve. On the professional C-type machine on the market, the hollow pipe for conveying fish must be equipped. The light-controlled signal detection feedback on the fish outlet of the whole machine starts the electric movable door card on the fish outlet of the fish collection box to release the fish. At the same time, the micro-motor booster gear kit is started to work, so as to achieve automatic and continuous fish delivery, so that the fish bodies do not overlap or get blocked, and ensure the high-efficiency continuous production and processing of the machine. The fish outlet of the hollow pipe for conveying fish is plugged and installed with the external short docking pipe port on the fixed transverse partition of the fish inlet pipe, and is made of stainless steel sheet.

[0018] 3. Fixed diaphragm and docking port of fish inlet pipe: It is installed and fixed on the left and right main frame plates at one end of the fish inlet of the whole machine. In the circular fish inlet opening on the plane of the diaphragm, a small section extends out from the inside and outside to form a short section of pipe welded horizontally front and back to form a double short opening, which is connected to the fish outlet of the machine's external accessories externally; and to the short pipe opening of the semi-fixed elastic fish control pipe internally. A notch is also reserved on this fixed diaphragm for installing the upper and lower movable transition tongue plates, which is made of stainless steel plate.

[0019] 4 Elastic fish control pipe: This elastic fish control pipe is divided into two sections, the front section is a short butt-jointed pipe port, and the rear section is made of two semicircular arc-shaped stainless steel sheets, which are made into a mechanical component with left and right flexibility, connecting the front and rear sections into one, one piece on the left and one piece on the right, parallel, with a spring limiting force that can stretch from left to right to fit the fish body tightly toward the center. Its function is to ensure that fish bodies of different sizes entering are limited, positioned, and passed by the center of the gear behind them. This piece is vertically supported on the upper and lower movable transition tongue plates, and can move up and down with them.

[0020] 5. Upper and lower movable transition tongue plate: It is a long stainless steel sheet, which is low in the middle and high on both sides to form a semicircular arc shape. The front end is semi-fixedly installed on the installation notch on the fixed transverse partition of the fish inlet pipe. There is a fixed long opening and a pair of pins in the rear part of the piece. The fish hooking and sending fish top supporting sharp gear piece is embedded in the middle of this long opening, and there is no contact cooperation on the side. Its tail is connected with the installation docking interface and plug-in connection on the elastic top supporting device seat arranged behind it, and is flexibly connected with the elastic top supporting device to form a front and back whole, forming a sliding bottom plate for the belly meat of the fish body, and cooperating with the upper layer knife gear to form a top supporting platform that balances the thickness of the fish body, and a meat cutting chopping board.

[0021] 6. The sharp gear for hooking fish, sending fish and supporting fish: It is a gear with a discrete motor, a gear box, a low-speed, high-torque power, and a specially made transmission shaft. It is composed of three gear plates arranged symmetrically and in parallel with the center of the transmission shaft. The sharp gear plate in the center is higher than the two thin gear plates symmetrical on the left and right. It is named the sharp gear for hooking fish, sending fish and supporting fish. Its function is: to cooperate with the double-layer composite wheel for positioning and sending fish that rides on the fish body, to compress and support the spine of the fish body from bottom to top, balance and disperse the volume of fish meat of different sizes, push the fish body to move in the direction of the next tool, prevent the fish body from twisting, and smoothly accept the cutting of the blade wheel inside the double-layer composite wheel for positioning and sending fish. To prevent obstruction by fish bodies that are too thick, the vertical center positioning points of the upper and lower sets of gears are offset by a few millimeters front and back for positioning and installation. The sharp gear for hooking fish, sending fish and supporting fish on the lower layer is slightly forward, and the double-layer composite wheel for positioning and sending fish installed on the upper layer is slightly backward, and they are not on the same vertical line.

[0022] 7. Double-layer composite wheel for positioning and feeding fish: It is powered by a main motor for high-speed cutting. It is centered on a specially made gear transmission shaft and is composed of three gear plates arranged symmetrically, parallelly and at intervals. The left and right outer sides are two outer guard plate wheel plates. The outer edges of these two wheel plates have symmetrically outward-turned edges. On the middle plate surface of these two outward-turned wheel plates, there are parabolic ribs with interval gaps. The purpose is to increase the friction margin for the thick fish body to bulge outward from the wheel plates, and to have a positioning effect to prevent the fish body from twisting and obstruction. On the inner single-blade gear plate in the middle of the double-layer composite wheel for positioning and feeding fish, there are evenly distributed several small rectangular teeth. With the cooperation of the outer guard plate wheel, the fish spine meat is compressed into an upright and compact state, and can vertically cut the fish back meat to expose the top of the spine. This composite gear is also one of the key gears that can be used in one machine. Take the C-type professional processing machine for example: on the left and right sides between the two outer guard wheels and the inner blade wheel, on the transmission shaft, there are short and round springs to ensure that it can automatically extend and retract between the minimum and maximum fish body widths, limit and balance the volume of the fish body, and also make detailed adjustments to the diameter and spacing of each gear of the whole machine.

[0023] 8. Deformed composite spine separation knife gear: To innovate electric tools, a round thin steel sheet with flexible elasticity and multi-petal small rectangular teeth is used. After mechanical stamping deformation and heat treatment, the outer edge of the circular single blade is deformed and bent to an angle of less than 5 degrees to the left and right, and the two pieces are combined to less than 10 degrees, depending on the size of the fish and the length of the blade. The deformation angle is determined by the size of the fish and the size of the blade. The left and right single blades are supported and matched with the prefabricated curved gear piece mounting boss on the gear transmission shaft, and are fixed with five thin screws and nuts. In order to make the gear firm and stable, special washers with curved thickening are also installed on the left and right end faces of the gear piece, so that the transmission shaft and the left and right gear pieces are more firmly fixed, and the tip of the blade is in an eight-shaped shape, with a single blade and double edges, so it is named: deformed composite spine separation knife gear. This knife gear, together with the double-layer composite wheel for positioning and feeding fish installed at the front end, and the front and rear sets of knife gears, are installed in parallel with the maximum safety staggered overlap and the upper and lower high and low position staggered positioning in order to shorten the gap in the connection lead of the front and rear knife gear combination connection. Because the shape of the fish body gradually changes from a cylinder to a slightly flat shape after the first cutting by the double-layer composite wheel for positioning and feeding fish, the positioning point of the rear-stage knife gear must be lowered for docking. The purpose is to ensure that the tip fork of the deformed composite spine separation knife gear can be accurately aligned and straddle the spine, and the hardness of the spine can be used to adjust the angle and width of the spine of large and small fish bodies freely. The front and rear sets of knife gears share a main motor, and are equipped with synchronous wheels and synchronous belts to provide high-speed cutting power.

[0024] 9 Elastic top support: It is composed of a concave lifting seat and a plug-in interface made of stainless steel plate, equipped with a moderately thick spring, a push rod, and an integral outer frame shell, which are combined into a detachable whole and installed vertically on the inner plane of the left and right main frame plates. Function of the elastic top support: After the fish bodies of different thicknesses are compressed, a free elastic top support force is generated, and the upper and lower movable transition tongue plate components are mutually movable and plug-in connected to form an integral whole. Its surface is semi-circular concave in front and back, which is the sliding bottom plate of the fish belly meat, guiding the fish body to pass through the first set of upper and lower gear cutting, and enter the combination section of the deformed composite spine separation knife gear and the elastic top support. Then, the spring top support force of the elastic top support component is used to support the fish body from bottom to top, so that the deformed composite spine separation knife gear becomes an eight-shaped blade tip, aligns with and straddles the top of the spine, deeply cuts the lower spine meat, and completes the spine separation. There are pins and positioning holes for adjusting the spring force on the upper part of the two push rods.

[0025] 10 Anvil wheel assembly: It includes an elastic guide rail component, which is an independent integral mechanical component. The anvil wheel is equipped with a discrete motor. The purpose of the motor is to ensure that the fish body has forward and backward pulling power during its forward and backward movement. Because the fish body will suddenly become a very thin and fine fish tail after reaching the cloaca section, it will lose the upper and lower clamping force of the gears and the pushing force of the motor. Therefore, the rear gear combination must maintain the pulling power. An assembly force structure metal frame is configured on the integral mechanical component. A small discrete motor is installed on the metal frame, and a reduction gear box is matched. The power is provided by the transmission of large and small gear pieces. The pulley installed on it can make the whole machine move forward and backward along the guide rail stroke. Four tension springs are used on the outer surfaces of the left and right main frame plates, two on the left and two on the right, and are positively assembled with the metal frame of the anvil wheel assembly to make the anvil wheel close to the segmented knife. The slice wheel uses an adjustable limit block to maintain safe contact. The chopping board wheel is made of hardwood or metal aluminum into an elongated flat roller with a smooth outer diameter. At the exact center circumference, a groove is cut to fit the spine, eliminating the continuous cutting process of the raised spine that has been separated from the spine front and back. The blades on the segmented blade wheel are installed obliquely, and the fish meat is cut off by the blade with gradual force. It is only used as a meat cutting chopping board. Also, because the spine is raised upward, and because the fish body has different thicknesses, and the same fish body has three sizes: a large head, a medium body, and a thin tail, it is necessary to design a functional component with automatic elastic guide adjustment to balance the thickness of the fish meat, and assemble it into an integral mechanism for synchronous activity adjustment. The flat fish meat is freely cut into segments by the spring telescopic force in cooperation with the segmented blade, and then diverted to the bottom of the machine and guided to the container for holding things.

[0026] 11. Segmented blade wheel and blade: It is an oblong flat roller wheel made of hardwood or metal aluminum, which is equipped with a discrete motor, gearbox, low speed and high torque. On the outer diameter surface of the roller, it can be left front and right rear or right front and left rear. There are three equally divided blade installation grooves that are offset to an angle of about 20 degrees. The inserted segmented blades are installed using these three oblique grooves on the roller surface. Blade pressure covers are arranged on the left and right end faces of the oblong flat roller to limit the movement of the blade. There are also grooves on the left and right end faces of the blade that match the pressure covers. Then a through-shaft threaded transmission shaft passes through the center of the wheel and is fastened with a nut to facilitate disassembly and replacement of the blade. The blade is set to be installed obliquely to prevent fish bones from being blocked during the cutting process and reduce resistance.

[0027] 12 Bearing positioning movable mounting hole plate: It is made of long thick stainless steel sheet. The whole machine bearings are selected with single-sided flange bearings, installed from the inside to the outside. In order to facilitate the disassembly and overlap of various parts, screws and nuts are used to install and position the inner and outer sides of each removable notch on the rectangular left and right frame plates. It is a two-sided assembly component.

[0028] 13 Gear transmission shaft: The whole machine has multiple types and sets of gear transmission shafts. The first type: There are two sets, namely the anvil wheel and the segmented blade wheel. Because they are all long drum wheels, their transmission shafts use through-shaft threaded shafts that are larger than the bearing installation shaft diameter, and are fastened and installed with left and right nuts; the second type: Each one is composed of two half-short shafts. On the left and right end faces of the center of the two short shafts, they are divided into left and right shafts, which are turned into circular right-angle and curved-angle gear blade installation fixed bosses that are larger than the shaft diameter. Then, on the center end face of this large-diameter boss, a short, center male and female mortise and tenon structure that is smaller than the shaft diameter is turned, and then multiple gear pieces are assembled and installed on the fixed boss from the inside to the outside or from the outside to the inside. After the male and female mortise and tenon joints in the center of the shaft are connected, five or six fine screws and nuts are used to fix the left and right. The reserved mounting holes on the shaft boss integrated with the transmission shaft and the multiple gear plates are penetrated and fixed to form a whole shaft with gear plates; the multiple gear plates are concentratedly assembled, and there are clearance requirements, requiring the gear plates to be straight and have small jitter deviation, high concentricity and easy disassembly and replacement of gear blades; the third type: the gear blade installation and fixing boss is turned into a circular gear with a curved surface larger than the shaft diameter at the center of the whole shaft to adapt to the deformed compound spine separation knife gear; the fourth type: to adapt to the professional machines in the C-type market, the requirements for the gear transmission shaft are higher and more complex, the principle is the same, and it is equipped with a thick and short spring and a gear clearance expansion and contraction adjustment functional component to ensure the performance of the machine, which is firm and reliable.

[0029] 14 sub-power motors: The whole machine has two sets of sub-power motors that require low speed, high torque, small size, and can be matched separately, namely, the fish hook and fish feeding top support tip gear and the segmented blade wheel. The anvil wheel assembly is equipped with a small sub-power motor and a reduction gearbox, which uses a large and small gear transmission combination to provide power.

[0030] 15 Removable notch: The function is to facilitate the assembly, maintenance and replacement of parts of the whole machine. At the installation and positioning points of each gear transmission shaft on the rectangular left and right main frame plates, a removable notch with the same width as the outer diameter of the bearing is sawed on the plate surface corresponding to the upper and lower outer edges of each vertical plate. The bearing is positioned with a movable mounting hole plate, and the bearing is installed and fixed with screws and nuts.

[0031] 2. Main motor and semi-fixed mounting base bottom plate: For the overall layout of the machine, to compress the overall volume of the machine and protect the main power motor and random electrical appliances from waterproofing and safety, they are centrally installed and fixed on the bottom plate of the motor semi-fixed mounting base, and a three-way baffle is installed to block the blood splashing generated by the gears cutting the fish. It acts as a baffle and is semi-fixed at the top of the machine, combined with the left and right main frame plates to form a detachable component. The main motor uses a synchronous wheel, and the synchronous belt is matched with the double-layer composite wheel for positioning and feeding fish and the deformed composite spine separation knife gear to provide high-speed cutting power. The mounting base bottom plate is made of thick stainless steel plate or aluminum plate.

[0032] 3. Removable and liftable base platform: In order to facilitate maintenance, cleaning and use, a base platform mechanical component is designed on the bottom plane of the main frame plate where the fish inlet and outlet are located, which enables the whole machine to have upright flipping and lifting functions. It also utilizes the physics that water flows to lower places and objects slide to lower places to solve the problems of fish meat sliding during the processing of fish, and blood and water quickly flowing to the fish outlet for centralized collection. The whole machine is made into an inclined machine with a high fish inlet and a low fish outlet when working. The overall installation and fixing base of the machine forms an upper and lower structure with the main frame. Two supporting lifting platforms, support rods and grooves are set on the front plane of the lifting base platform. The purpose is to lift and place the main frame. The extended section of the long screw rod used for fixing the rectangular left and right frame plates is placed in the left and right support rods and grooves, and then tightened and fixed with manual winged nuts. Two low supporting platforms, support seats and grooves are also set at the rear end of the base platform. The extended interlaced fixed long screw rods on the rear ends of the left and right main frame plates are placed in the support grooves, and then tightened and fixed with winged nuts.

Specific implementation method:

[0043] The present invention is further described as follows with reference to the accompanying drawings and embodiments:

[0044] The implementation method is as follows: it is divided into three major components: 1. the main frame component; 2. the main motor and the semi-fixed mounting base plate; 3. the detachable lifting base platform, and its shape and structure are described as follows:

[0045] 1. The main frame components include: 1. left and right main frame plates; 2. hollow pipes for conveying fish bodies and docking ports; 3. fixed transverse partitions and docking ports for fish inlet pipes; 4. elastic fish control pipes; 5. upper and lower movable transition tongue plates; 6. tip gears for hooking and delivering fish; 7. double-layer composite wheels for positioning and delivering fish; 8. deformable composite spine separation knife gears; 9. elastic top supports; 10. anvil wheel assembly and elastic guide rail components; 11. segmented blade wheels and blades; 12. bearing positioning movable mounting hole plates; 13. gear transmission shafts; 14. power motors; 15. removable notches.

[0046] 1 Left and right main frame plates: Two rectangular thick stainless steel plates or aluminum plates are used. Four holes 35 for inserting long screw rods for fixing are drilled on the outer edges of the front, back, upper and lower corners of the rectangular left and right main frame plates 1. Four main frame fixing long screw rods 35 are fixed in parallel to form a complete main frame body 1. All gears, tools, gear power distribution motors 14, transmission shafts 13, and bearing positioning movable mounting hole plates 12 are assembled on the rectangular left and right main frame plates 1 of the complete machine. In order to facilitate the assembly and maintenance of the whole machine, as well as the replacement and disassembly of individual gears and parts, the upper and lower gear transmission shafts 13 on the rectangular left and right main frame plates 1 are installed with fixed positioning points, and a removable notch 15 with a width equal to the outer diameter of the bearing is sawn on the upper and lower outermost edges in the vertical directions corresponding to the left and right frame plates, and then the bearing positioning movable mounting hole plate 12 is used to position each gear transmission shaft 13 and the bearing so that they can be disassembled, overlapped, and fixed accordingly; a notch 25 is also sawn obliquely at the rear end of the rectangular left and right main frame plates 1, and an anvil wheel assembly and an elastic guide rail component 10 are installed.

[0047] 2. Hollow pipe for conveying fish and docking port: This component can be omitted on the A and B models of the machine. Instead, a simple plastic fish basket and the hollow plastic pipe on it can be used. The fish can be released by a manual valve switch. However, it must be matched on the professional C-type machine in the market. The hollow pipe for conveying fish is fed back by the light control signal detection on the fish outlet of the whole machine. The electric movable door card on the fish outlet of the fish collecting box is started to release the fish. At the same time, the micro motor booster gear kit is started to work, so as to achieve automatic and continuous fish delivery, so that the fish bodies do not overlap or get blocked, and ensure the high-efficiency continuous production and processing of the machine. The fish outlet port of the hollow pipe for conveying fish is plugged and installed with the outer short docking pipe port on the fixed transverse partition 3 of the fish inlet pipe.

[0048] 3. The fish inlet pipe fixed diaphragm and docking port 3: installed and fixed on the left and right main frame plates 1 at one end of the fish inlet of the whole machine, on the fish inlet circular opening on the inner and outer planes of the diaphragm, a small section is extended inside and outside to form a short pipe opening horizontally welded front and back, which is connected to the fish outlet of the supporting parts outside the machine; it is connected to the short pipe opening of the semi-fixed elastic fish control pipe 4 inside. This fixed diaphragm 3 also has feet and notches 27 positions installed with the upper and lower movable transition tongue plates, which are made of stainless steel sheets.

[0049] 4 Elastic fish control pipe 4: This elastic fish control pipe is composed of two sections, the front section is a short plug-in pipe mouth, and the rear section is made of two semicircular arc-shaped stainless steel sheets, which are made into a mechanical component with left and right flexibility, connecting the front and rear sections into one, one piece on the left and one piece on the right, parallel and tightly fitting the fish body, with a spring limiting force that stretches from left to right to the center, and its function is to ensure that fish bodies of different sizes entering are limited and positioned to the center of the gear behind them, and pass through. This part is vertically supported on the upper and lower movable transition tongue plate 5 and can move up and down with it.

[0050] 5 The upper and lower movable transition tongue plate 5 is a long stainless steel sheet, which is low in the middle and high on both sides to form a semicircular arc. The front end is semi-fixedly installed on the tongue plate mounting notch 27 on the fish inlet fixed transverse partition of the fish inlet pipe at the fish inlet, and its tail is semi-fixedly plugged with the mounting interface 9 on the elastic top support device installed behind it, and is positioned and connected with the elastic top support device 9 to form a front and rear whole, forming a sliding bottom plate for the belly meat of the fish body and a fish body lifting and supporting platform. There is a fixed long opening 34 in the rear part of the piece, which is embedded on the left and right sides of the hook fish feeding fish top supporting tip gear 6.

[0051] 6. The hooked fish feeding fish top supporting sharp gear 6: It is a gear with a discrete motor 14, a gear box 39, a low-speed, high-torque power, and a specially made transmission shaft 13. With the transmission shaft center, it is symmetrically arranged in parallel and composed of three gear pieces. A long gear piece in the center is higher than two symmetrical fine-toothed gear pieces, named as the hooked fish feeding fish top supporting sharp gear 6. Its function is: cooperate with the positioning fish feeding double-layer composite wheel 7 riding on the fish body to compress and support the spine of the fish body from bottom to top, balance and disperse the volume of fish meat of different sizes, and push the fish body to move in the direction of the next tool; it can prevent the fish body from twisting and smoothly accept the cutting of the blade wheel 37 inside the positioning fish feeding double-layer composite wheel; in order to prevent the obstruction of the fish body that is too thick, the vertical center positioning points of the upper and lower sets of gears are positioned and installed with a few millimeters offset front and back, and the hooked fish feeding fish top supporting sharp gear 6 on the lower layer is slightly forward, and the positioning fish feeding double-layer composite wheel 7 installed on the upper layer is slightly backward, and they are not on the same vertical line. The fish hooking and sending fish top supporting pointed gear 6 and the positioning and sending fish double-layer composite wheel 7 have a spine size to ensure the gap between the upper and lower knives and the teeth. It is necessary to obtain the gear diameter and the size of the installation positioning point through testing and according to the range of fish body thickness conditions.

[0052] 7 Positioning and feeding fish double-layer composite wheel 7: A main motor 20 provides high-speed cutting power, with a specially made gear transmission shaft 13 as the center, symmetrically parallel and spaced, and composed of three gear plates. The left and right outer sides are two outer guard plate wheels 36. On the outer edges of these two wheel plates, there are symmetrically outward-turned edges 42. On the middle plate surface of these two outward-turned wheel plates, each is processed with a parabolic rib 41 with a gap between the widths, the purpose is to increase the friction margin for the over-thick fish body to bulge outward from the wheel plate, have positioning, prevent the fish body from twisting and obstruction, and disperse the volume of the fish belly meat; in the positioning and feeding fish double-layer composite wheel On the inner blade wheel 37 in the middle of the combined wheel 7, there are a number of small rectangular blade teeth evenly distributed. With the cooperation of its outer guard wheel 36, the fish spine is compressed into an upright and compact state, and the spine is cut vertically to expose the spine. This composite wheel 7 is one of the key gears that can be used in one machine. Taking the C-type market professional processing machine as an example: on the left and right sides between the two outer guard wheels 36 and the inner blade wheel 37, thick and short springs should be installed to ensure automatic expansion and contraction between the minimum and maximum fish body widths, adjust the blade gear spacing, limit and balance the fish body volume, and also make detailed adjustments to the diameters of each gear of the whole machine. The finer the adjustment, the less waste of residual spine meat on the spine.

[0053] 8 Deformed composite spine separation knife gear 8: It is an innovative electric tool, using a special gear transmission shaft 13, a thickened special gasket 19 to combine together, using a round thin steel sheet, a steel flexible elastic, multi-petal small rectangular blade single blade gear piece, deformed and bent into an angle of less than 5 degrees to the left and right, the two pieces are combined into two single blades with an angle of less than 10 degrees, these two single blades are supported and matched with the prefabricated curved mounting boss 16 on the gear transmission shaft 13, in order to make the gear firm and stable, a curved thickened special gasket 19 is installed on the left and right of the gear piece, and several thin screws and nuts 18 are used to penetrate the preset mounting holes to fix them, and they are combined into one, the tip of the blade is in an eight-shaped shape 33, a single blade with two edges, named deformed composite spine separation knife gear 8; this knife gear, together with the positioning transmission The two sets of knife gears before and after the double-layer composite wheel 7 for fish use the shortest idle lead, and the wheel pieces are overlapped and installed with the maximum permissible cross amount, while the upper and lower horizontal plane fixed points are changed to be installed in an upper and lower offset manner. Because the fish body gradually changes from a cylindrical shape to a flat shape after the first cutting by the double-layer composite wheel 7 for positioning and sending fish, the positioning point of the rear-stage knife gear must be lowered for docking, in order to ensure that the tip fork 33 on the deformed composite spine separation knife gear 8 is accurately aligned and straddles the spine, and utilizes the hardness of the fish spine and the upper narrow and lower wide width of the spine of large and small fish bodies to be flexible and retractable, automatically limiting deep cutting for large fish and shallow cutting for small fish, and sharing a main motor 20 with the two sets of knife gears before and after the double-layer composite wheel 7 for positioning and sending fish, and using a synchronous wheel 21 and a synchronous belt 22 to provide high-speed cutting power.

[0054] 9 Elastic top support 9: In order to control and balance the fish body and the upper and lower movable transition tongue plate 5 components, the bottom surfaces of the two components are semicircular concave surfaces in front and back, which are sliding bottom plates for the belly meat of the fish body, guiding and limiting the fish body to pass through the first set of upper and lower gear cutting, and enter the combination section of the deformed composite spine separation knife gear 8 and the elastic top support 9. The spring top force of the elastic top support 9 component is used to support and cooperate from bottom to top, so that the deformed composite spine separation knife gear 8 is formed into an eight-shaped blade tip 33, and the V-shaped fish back meat gap is aligned with the top of the spine, and the lower layer of the spine meat is cut closely to the spine. There are pins and positioning holes 51 for adjusting the spring force on the upper part of the two top rods 44.

[0055] 10 Anvil wheel assembly: including elastic guide rail component 10, which is an independent integral mechanical component. Anvil wheel 10 is equipped with discrete motor 14. The purpose of the motor is to ensure that the fish body has forward and backward pulling power during the forward and backward movement. Because the fish body will suddenly become a very thin and fine fish tail after reaching the cloaca section, it will lose the upper and lower clamping force of the gear and the pushing force of the motor. Therefore, the rear gear combination must maintain the pulling power. An assembly force structure metal frame 53 is configured on the integral mechanical component. A small discrete motor 14 is installed on the metal frame 53, and a reduction gear box 39 is matched. The large and small gear transmission combination 52 provides power. The pulley 46 installed thereon can make the whole machine move forward and backward along the guide rail stroke 10. Four tension springs 50 are used on the outer surfaces of the left and right main frame plates 1, two on each side, to form a positive assembly with the anvil wheel assembly metal frame 53. The chopping wheel 10 is placed close to the segmented blade wheel 11 and an adjustable limit block is used to maintain safe contact. The chopping wheel is made of hardwood or metal aluminum to form an elongated flat roller with a smooth outer diameter. A groove 49 is cut at the exact center circumference to fit the spine, eliminating the continuous cutting process of the raised spine that has separated the spine meat front and back. The blades on the segmented blade wheel 11 are installed obliquely, and the fish meat is cut off by the blade with gradual force. It is only used as a meat cutting chopping board. Also, because the spine is raised upward, and because the fish body has different thicknesses, and the same fish body has three sizes: a large head, a medium body, and a thin tail, it is necessary to design a functional component with automatic elastic lead adjustment to balance the thickness of the fish meat, and assemble it into an integral mechanism for synchronous activity adjustment. The spring telescopic force cooperates with the segmented blade 11 to freely cut the flat fish meat into segments, and then divert it to the container below the machine.

[0056] 11. Segmented blade wheel and blade: The segmented blade wheel and blade 11 are an oblong flat roller wheel made of hardwood or metal aluminum material, which is matched with a discrete motor 14, a gear box 39, a low speed and a large torque. The roller outer diameter surface can be left front and right rear or right front and left rear. The oblique cutting process has three evenly divided upper and lower blade installation bevel grooves 2 that are offset to an angle of about 20 degrees. The three bevel grooves 2 on the roller surface are used to install the inserted segmented blade 11. Then, on the left and right end faces of the oblong flat roller, blade pressure covers 40 are arranged to limit the movement of the blade. There are also grooves on the left and right end faces of the blade that match the pressure cover 40. Then, a through-wire transmission shaft 17 is passed through the center and fastened with a nut to facilitate the disassembly and replacement of the blade. The blade is set to be installed obliquely to prevent the fish bones from being blocked during the cutting process.

[0057] 12 bearing positioning movable mounting hole plate: 12 is made of a long thick stainless steel sheet. The whole machine bearings are selected with single-sided flange bearings 48, which are installed from the inside to the outside. In order to facilitate the disassembly and overlap of various parts, screws and nuts are used to install and position them on the inside and outside of each removable notch 15 on the rectangular left and right frame plates 1. It is a two-sided assembly component.

[0058] 13 Gear transmission shaft 13: The whole machine has several types of gear transmission shafts. Those with gear blade mounting and fixing bosses 16 in the center of the shaft are marked as 13, and those with through-shaft threaded shafts for long drum wheels are marked as 17, i.e., those for anvil wheels and segmented blade wheels 11, which are all positioned and installed with left and right nuts; There are two types of gear blade mounting and fixing bosses 16 in the center of the shaft: one type is that each shaft is composed of two half-short shafts, and the left and right shafts are divided on the left and right end faces of the center of the two short shafts, and are turned into circular gear blade mounting and fixing bosses 16 with right angles and curved surfaces larger than the shaft diameter, and then a short center male and female mortise and tenon structure 45 smaller than the shaft diameter is turned on the center of this large-diameter boss 16 to move multiple gear pieces from the inside to the outside or from the outside to the inside. The inner part is centrally assembled on this mounting and fixing boss 16, and after the male and female mortise and tenon 45 in the center of the shaft is connected, five fine screws and nuts 18 are used to penetrate and fix the fixing bosses 16 on the left and right shafts and the reserved mounting holes 18 on the multiple gear pieces to form a whole shaft with gear pieces; because there are multiple gear pieces to be centrally assembled, and there are clearance requirements, the gear pieces are required to be straight and have small jitter deviation, high concentricity and convenient disassembly and replacement of gear blades, etc., like the top supporting tip gear 6 for hooking fish and sending fish, the double-layer composite wheel 7 for positioning fish and sending fish, the gear blade is suitable in the center position of the shaft, and the deformed composite spine separation knife gear 8 can use a whole shaft, a gear blade is installed on the fixed center boss 16, and the special washer 19 with curved surface thickening is assembled into one with fine screws and nuts 18. The other is the gear transmission shaft of the professional C-type machine in the large market: short and thick springs should be installed on the left and right sides between the two outer guard wheels 36 and the inner blade wheel 37 to ensure automatic extension and retraction between the minimum and maximum fish body widths, adjust the blade gear spacing, and limit the balanced fish body volume. This requires the shaft diameter, short and thick springs, fixed boss 16, the two outer guard wheels 36, and the inner blade wheel 37 to be refined in design and configuration when the whole machine is mass-produced. The principles are the same, but the sizes and shapes are different, and they are temporarily marked as 13.

[0059] 14 sub-power motors 14: The whole machine has three sets of sub-power motors 14 that require low speed, high torque, and small size and can be matched separately, namely the fish hooking and feeding fish top supporting tip gear 6 and the segmented blade wheel and blade 11. The anvil wheel assembly is equipped with a small sub-power motor, a matching reduction gear box, and a large and small gear piece combined transmission to provide power.

[0060] 15 Removable notch: The function is to facilitate the assembly, maintenance and replacement of parts of the whole machine. At the installation and positioning points of each gear transmission shaft 13 on the rectangular left and right main frame plates 1, corresponding to the main frame plate surface 1 between the respective vertical upper and lower outer edges, a removable notch 15 with the same width as the outer diameter of the bearing 48 is sawed, and the movable installation hole plate 12 is positioned with the bearing, and fixed with screws and nuts.

[0061] 2. Main motor and semi-fixed mounting base bottom plate 23: In order to arrange the whole machine, reduce the volume of the whole machine, protect the main power motor 20 and the waterproof safety of the whole machine electrical appliances, the main motor and the whole machine electrical appliances are centrally mounted and fixed on the motor semi-fixed mounting base bottom plate 23, which has the function of blocking the splashing blood generated by the gears when cutting the fish meat, and has a waterproof shielding three-way baffle plate 47, which is seamlessly protected with the mounting base bottom plate 23. The main motor 20 on the left and right main frame plates 1 is connected and matched with the synchronous wheel 21 and the synchronous belt 22 for positioning the fish feeding double-layer composite wheel 7 and the deformed composite spine separation knife gear 8 to provide high-speed cutting power. The semi-fixed mounting base bottom plate 23 is made of thick stainless steel plate or aluminum plate.

[0062] 3. Removable and liftable base platform 24: A semi-fixed base platform 24 is used for installing the whole machine. It is made of thick stainless steel sheet metal. In order to facilitate maintenance, cleaning and use, a base platform 24 mechanical component is designed on the bottom plane of the main frame plate 1 for the fish inlet and outlet to enable the whole machine to have upright flipping and lifting functions. It also uses the physics that water flows to lower places and objects slide to lower places to solve the problems of fish meat sliding during the processing of fish bodies, and blood water flowing quickly to the fish outlet for centralized collection. The whole machine is made into an inclined machine with a high fish inlet end and a low fish outlet end when working. The mounting and fixing base 24 of the whole machine forms an upper and lower structure with the main frame 1. Two supporting and lifting platforms, support rods and grooves 32 are set on the front plane of the lifting base platform 24. The purpose is to lift and place the main frame 1. The extended section of the long screw 35 used for fixing the rectangular left and right frame plates 1 is placed in the left and right support rods and grooves 32, and then tightened and fixed with a manual winged nut 29. Two low supporting platforms, support seats and grooves 30 are also set at the rear end of the base platform. The extended interlaced fixed long screw 35 on the rear end of the left and right main frame plates is placed in the support groove 30, and then tightened and fixed with a winged nut 29 that is convenient for manual tightening. Another function is to place the entire machine flat on the storage platform seat to reduce the volume after cleaning and drying.

[0063] The technology still uses dual-speed technology: the upper tool mechanism runs at high speed, and the lower fish feeding gear runs at low speed, forming two speed differences between the upper and lower parts, so that the fish body passively accepts cutting while moving at a low speed.
