Description

Technical Field

[0001] The invention relates to the technical field of fish processing, and in particular to a flushing type automatic bone removal and sorting device for processing fish food. Background Art

[0002] Fish meat is tender, delicious, nutritious, and a good source of vitamins and minerals, and is widely loved by people. Before cooking, fish needs to be slaughtered, but it is very troublesome and requires manual removal of the internal organs. If a single family uses manual methods, it is acceptable, but for restaurants or processing plants, manual methods will lead to low efficiency.

[0003] The existing fish killing machines use different knives for cutting open the fish belly and scraping off the internal organs. Since the directions of the fish cutting knife and the internal organs scraping knife are different, after the fish belly is cut open, the internal organs scraping knife is sometimes difficult to align with the incision of the fish belly, resulting in the scraping knife being unable to smoothly enter the fish belly. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a flushing type automatic bone removal and sorting device for processing fish food.

[0005] The technical solution of the present invention is: a flushing type automatic deboning and sorting device for processing fish food materials, comprising a classification box, two groups of fish conveying units arranged in parallel on the top surface of the classification box, a visceral removal unit arranged between the two groups of fish conveying units, and a deboning unit arranged on one side of the two groups of fish conveying units; the top surface of the classification box is provided with a first opening, a second opening, and a third opening for collecting viscera, fish meat, and fish bones in sequence; the visceral removal unit comprises a fixed plate fixedly arranged in the first opening, a visceral removal knife arranged on the fixed plate, and a lifting mechanism for driving the visceral removal knife to rise and fall; the visceral removal knife comprises a knife shaft vertically slidably arranged on the fixed plate, a fixed knife fixedly sleeved on the knife shaft and used for cutting open the fish belly, and two movable knives rotatably sleeved on the knife shaft and respectively located on both sides of the fixed knife; an opening and closing mechanism for controlling the two movable knives to unfold or retract is provided between the two movable knives, and a flushing water pipe for flushing the visceral removal knife is provided on one side of the fixed plate.

[0006] Description: The above device conveys fish through the fish conveying unit. When the fish passes through the eviscerating knife, the fixed knife will cut the fish belly. Since the movable knife is in the retracted state in the initial state, the eviscerating knife can enter the fish belly without aligning with the incision and will not cause damage to the fish meat. Then, the knife shaft is driven up by the lifting mechanism to make the eviscerating knife enter the fish belly as a whole, and the two movable knives are expanded outwards through the opening and closing mechanism. As the fish continues to be conveyed, the expanded movable knife will scrape the internal organs in the fish belly.

[0007] Further, the opening and closing mechanism includes a plurality of connecting rods arranged on each movable knife and hinged with the movable knife, a pull rod vertically arranged between two movable knives and rotatably connected with the plurality of connecting rods, and an annular air bag sleeved on the knife shaft above the fixed plate;

[0008] A pneumatic rod is fixedly arranged on the fixed knife and drives the pull rod to move by charging and discharging air. The pneumatic rod is connected with the annular airbag through an air pipe. A pressure ring is sleeved on the knife shaft and squeezes the annular airbag by descending.

[0009] Note: In the initial state, the annular airbag is in a compressed state. As the knife shaft rises, the annular airbag will recover and inhale, shortening the air pressure rod and driving the pull rod to move. The pull rod will push the two movable knives to expand outward through the connecting rod, so that the movable knives can expand outward while the knife shaft rises, without additional operation.

[0010] Furthermore, the two groups of fish conveying units are both transported by rotating conveyor belts, and a first driving mechanism for driving the two conveyor belts to rotate is provided in the classification box.

[0011] Description: The driving mechanism can drive the two conveyor belts to rotate in opposite directions. The fish will move forward under the friction of the conveyor belts. The transportation is stable and the operation is easy.

[0012] Furthermore, two connecting strips corresponding to the positions of the fish conveying units are provided in the classification box, and the rollers of the two conveyor belts pass through the slide grooves provided on the top surface of the classification box and are rotatably connected with the corresponding connecting strips;

[0013] A second driving mechanism is arranged in the classification box and is used for pushing two connecting strips to slide so as to adjust the distance between two groups of fish conveying units.

[0014] Description: The second driving mechanism can be used to push the connecting strip to move, so that the two groups of fish conveying units move closer to the middle or separate to the sides, so that the distance between the two conveyor belts can be adjusted according to the size of the fish, ensuring the clamping force of the conveyor belt on the fish and preventing the fish from falling during transportation.

[0015] Furthermore, the first driving mechanism comprises a dial disposed at the lower end of the roller shaft on one side of each group of fish conveying units, a rotating rod disposed transversely in the classification box, and a driving element disposed on the side wall of the classification box;

[0016] The rotating rod is fixedly sleeved with two spiral blades corresponding to the dial for transmission, and the spiral directions of the two spiral blades are opposite. One end of the rotating rod passes through the side wall of the classification box and is connected to the driving element.

[0017] Description: The driving element can drive the rotating rod to rotate, so that the two spiral blades can drive the two dials to rotate in the opposite direction, so that the two conveyor belts rotate in the opposite direction. There is no need to set up two motors, which saves more energy and does not need to match the rotation speed of the two conveyor belts.

[0018] Furthermore, there is an angle difference of 90 to 180 degrees between the rotation angles of the two spiral blades, a liquid storage tube arranged parallel to the rotating rod and used for storing cleaning agent is provided on one side of the rotating rod, the liquid storage tube is fixedly connected to the side wall of the classification box, a sliding sleeve is provided on the sliding sleeve of the liquid storage tube, and a pressurizing device for pressurizing the interior of the liquid storage tube is provided at one end; two friction columns are provided in parallel on the side wall of the sliding sleeve located between the two spiral blades, which are used to contact the two spiral blades alternately to push the sliding sleeve to slide back and forth, the interior of the sliding sleeve is hollow and a mixing chamber is provided on the side wall, the mixing chamber is connected with the flushing water pipe, a plurality of strip liquid outlets are provided on the surface of the liquid storage tube located in the moving interval of the sliding sleeve, and a sealing plate is provided on the strip liquid outlet to be swingably connected to it through a torsion spring, the sealing plate is sealed and connected to the strip liquid outlet in a horizontal state, and a shifting block is provided on the sealing plate, a shifting plate is provided in the sliding sleeve to shift the shifting block to make the sealing plate swing to open the strip liquid outlet, both ends of the sliding sleeve are slidingly and sealingly connected to the liquid storage tube, and the sliding sleeve is connected to the mixing chamber through a pressure valve.

[0019] Description: When the two spiral blades rotate, they can alternately contact the two friction columns, so that the sliding sleeve can slide back and forth on the liquid storage tube. The sliding sleeve will push the sealing plate to swing back and forth through the paddle plate, so that the strip liquid outlet will intermittently open to release the cleaning agent, so that the cleaning agent enters the mixing chamber through the sliding sleeve and mixes with the flushing water. The mixing amount of the cleaning agent can be controlled by controlling the rotation speed of the spiral blades. At the same time, the sliding sleeve will drive the flushing water pipe to slide back and forth, thereby increasing the flushing range of the flushing water pipe.

[0020] Furthermore, the distance between the two friction columns is equal to the minimum distance between the two spiral blades.

[0021] Note: Limiting the distance between the two friction columns can ensure the sliding distance of the sliding sleeve and avoid the flushing range of the flushing water pipe being too small.

[0022] Furthermore, the deboning unit includes an N-shaped frame slidably arranged on the top surface of the classification box, and a displacement mechanism for driving the N-shaped frame to slide on the top surface of the classification box; a telescopic rod is respectively provided on the two side walls of the N-shaped frame, and a clamping blade is respectively provided on the corresponding end of the two telescopic rods; a meat-cutting blade is slidably arranged on the top surface of the classification box between the fish conveying unit and the clamping blade, and the meat-cutting blade is clamped to the clamping blade by a clamping device.

[0023] Description: When the fish head is transported to the deboning unit, the telescopic rod can be used to control the clamping blade and the meat dividing blade to cut into the fish meat. Then the displacement mechanism drives the N-shaped frame to slide, so that the clamping blade drives the fish head to continue to move forward. Since the fish meat is blocked by the meat dividing blade, the fish meat will be separated from the fish bones under the action of the meat dividing blade.

[0024] The beneficial effects of the present invention are:

[0025] (1) The present invention conveys fish through a fish conveying unit. When the fish passes through the evisceration knife, the fixed knife will cut the fish belly. Since the movable knife is in a retracted state in the initial state, the evisceration knife can enter the fish belly without aligning with the incision and will not cause damage to the fish meat. Subsequently, the knife shaft is driven up by the lifting mechanism to allow the evisceration knife to enter the fish belly as a whole, and the two movable knives are expanded outward by the opening and closing mechanism. As the fish continues to be conveyed, the expanded movable knife will scrape the internal organs in the fish belly.

[0026] (2) The present invention can use the second driving mechanism to push the connecting strip to move, so that the two groups of fish conveying units move closer to the middle or separate to the sides, so that the distance between the two conveyor belts can be adjusted according to the size of the fish, thereby ensuring the clamping force of the conveyor belt on the fish and preventing the fish from falling during the conveying process.

[0027] (3) When the two spiral blades of the present invention rotate, they can alternately contact the two friction columns, so that the sliding sleeve can slide back and forth on the liquid storage tube. The sliding sleeve will push the sealing plate to swing back and forth through the paddle plate, so that the strip liquid outlet will intermittently open to release the cleaning agent, so that the cleaning agent enters the mixing chamber through the sliding sleeve and mixes with the flushing water. The mixing amount of the cleaning agent can be controlled by controlling the rotation speed of the spiral blades. At the same time, the sliding sleeve will drive the flushing water pipe to slide back and forth, thereby increasing the flushing range of the flushing water pipe. BRIEF DESCRIPTION OF THE DRAWINGS

The two rotating sleeves are respectively located on the upper and lower sides of the fixed sleeve. Preferably, in order to ensure that the movable knife 33 can be smoothly deployed, the two rotating sleeves are connected to the fixed sleeve by a torsion spring.

[0042] An opening and closing mechanism for controlling the two movable knives 33 to unfold or retract is provided between the two movable knives 33. The opening and closing mechanism includes two connecting rods 331 provided on each movable knife 33 and hinged to the movable knife 33, a pull rod 38 vertically provided between the two movable knives 33 and rotatably connected to the four connecting rods 331, and an annular air bag 312 sleeved on the knife shaft 31 above the fixed plate 3; the movable knife 33 is hinged to the connecting rod 331 through a rotating shaft fixed thereon;

[0043] The fixed knife 32 is fixed with a pneumatic rod 381 that drives the pull rod 38 to move by charging and discharging air. The pneumatic rod 381 adopts the existing technology product. The pneumatic rod 381 is connected with the annular airbag 312 through the air pipe. The knife shaft 31 is sleeved with a pressure ring 313 that squeezes the annular airbag 312 by descending.

[0044] The lifting mechanism includes a threaded sleeve 34 rotatably arranged on the bottom surface of the fixed plate 3 and threadedly connected to the knife shaft 31, a sliding rod 37 vertically arranged on the bottom surface of the fixed plate 3, and a first motor 36 fixedly arranged on the bottom surface of the fixed plate 3; the first motor 36 adopts the existing technology product; the thread of the knife shaft 31 is arranged at its lower part;

[0045] The threaded sleeve 34 is fixedly sleeved with a first gear 35, the output shaft of the first motor 36 is provided with a second gear 361 for meshing with the first gear 35, and the knife shaft 31 is slidably connected with the slide rod 37 via a limit block 311 provided at its lower end;

[0046] like Figure 1 As shown, a flushing water pipe 39 for flushing the evisceration knife is provided on the left side of the fixed plate 3, and the flushing water pipe 39 passes through the side wall of the classification box 1;

[0047] The two groups of fish conveying units are both conveyed by rotating the conveyor belt 2. Each group of fish conveying units includes two rollers 21 vertically arranged on the top surface of the classification box 1, and a conveyor belt 2 sleeved on the two rollers 21; the two rollers 21 pass through the top surface of the classification box 1, and the classification box 1 is provided with a first driving mechanism for driving the rollers 21 to rotate. The first driving mechanism is a driving motor respectively arranged on the two shaft rollers 21 on the left side, and the driving motor adopts a prior art product;

[0048] The deboning unit adopts a commercially available fish bone deboning device. Preferably, a PLC controller is provided on the top surface of the classification box 1, and an image sensor is provided on the fixed plate 3. The image sensor and the PLC controller both adopt existing technology products, and the image sensor is electrically connected to the PLC controller. The first motor 36 and the drive motor are electrically connected to the PLC controller through a relay.

[0049] The working principle of the above device is as follows: in the initial state, the annular airbag 312 is in a compressed state, the meat dividing blade 42 and the clamping blade 41 are clamped by the clamping device, the two movable knives 33 are retracted to the middle, the driving motor is started, the shaft roller 21 drives the two conveyor belts 2 to rotate in the opposite direction, the fish is placed between the two conveyor belts 2, the conveyor belt 2 drives the fish to move to the right, when the fish moves to the position of the fixed knife 32, the image sensor transmits a signal to the PLC controller, and the fish belly is cut by the fixed knife 32, and the PLC controller can control the first motor 36 to rotate, and the first motor 36 is connected to the first gear 361 through the second gear 362. The gear 35 drives the threaded sleeve 34 to rotate, so that the knife shaft 31 drives the pressure ring 313 to rise. At this time, the annular airbag 312 begins to inhale and recover, so that the pneumatic rod 381 is shortened and pulls the pull rod 38 to move. The pull rod 38 pushes the two movable knives 33 to expand to both sides through the connecting rod 331. As the fish continues to move to the right, the two movable knives 33 will scrape the internal organs of the fish, and the internal organs will fall onto the fixed plate 3 under the action of gravity. At the same time, the flushing water pipe 39 can flush the fixed plate 3, so that the internal organs fall from the first opening 11 to the internal organ storage area 12; as the fish continues to move to the right, the fish enters the deboning unit to remove the fish bones.

[0050] Example 2: Figure 3 As shown, this embodiment is basically the same as the embodiment 1, except that the deboning unit includes an N-shaped frame 4 slidably arranged on the top surface of the classification box 1, and a displacement mechanism for driving the N-shaped frame 4 to slide on the top surface of the classification box 1; the classification box 1 is slidably connected to both sides of the N-shaped frame 4 through a guide groove provided on the top surface, and a telescopic rod 43 is respectively provided on the left and right side walls of the N-shaped frame 4, and the telescopic rod 43 adopts a commercially available electric telescopic rod, and a clamping blade 41 is respectively provided at the corresponding ends of the two telescopic rods 43;

[0051] A meat dividing blade 42 is slidably disposed on the top surface of the classification box 1 between the fish conveying unit and the clamping blade 31. The meat dividing blade 42 is clamped with the clamping blade 41 through a clamping device. The clamping device is a clamping column disposed on the clamping blade 41 and a clamping hole disposed on the meat dividing blade 42 for clamping with the clamping column.

[0052] The displacement mechanism includes two screw rods 44 respectively arranged on the left and right sides of the N-shaped frame 4, the two screw rods 44 are rotatably connected to the connecting plate provided on the top surface of the classification box 1, and one end of the two screw rods 44 is sleeved with a pulley 45, and the two pulleys 45 are driven by a transmission belt, and the other end of one of the screw rods 44 is provided with a driving motor for driving its rotation, and the driving motor adopts the existing technology product, and the two screw rods 44 are threadedly connected with movable blocks 46, and the two movable blocks 46 are fixedly connected to the side wall of the N-shaped frame 4;

[0053] An image sensor is disposed on the side wall of the N-shaped frame 4 . The image sensor adopts a prior art product, and the image sensor and the telescopic rod 43 are electrically connected to the PLC controller.

[0054] The working principle of the above-mentioned deboning unit is as follows: when the gills of the fish enter the N-type frame 4, the image sensor transmits a signal to the PLC controller, and the PLC controller controls the extension of the telescopic rod 43 to make the clamping blade 41 and the meat-cutting blade 42 cut into the fish meat, and then the driving motor drives the two screws 44 to rotate, so that the N-type frame 4 moves to the right. At this time, the clamping blade 41 drives the fish head and fish bones to move to the right and separate from the meat-cutting blade 42. The two meat-cutting blades 42 will hinder the movement of the fish meat, so that the fish meat is separated from the fish bones. The fish meat then falls from the second opening 16 to the fish meat storage area 13 under the action of gravity, and the fish head and fish bones continue to move to the right and fall from the third opening 17 to the fish bone storage area 14 under the action of gravity.

[0055] Embodiment 3: This embodiment is basically the same as Embodiment 2, except that the clamping device is a magnetic block arranged on the clamping blade 41 and the meat cutting blade 42.

[0056] The working principle of the above-mentioned clamping device is that when the clamping blade 41 and the meat-cutting blade 42 are close to each other, they are attracted together under the action of magnetic force.

[0057] Example 4: Figure 5 As shown, this embodiment is basically the same as the embodiment 1, except that two connecting strips 22 corresponding to the positions of the fish conveying units are provided in the classification box 1, and the rollers 21 of the two conveyor belts 2 pass through the slide grooves provided on the top surface of the classification box 1 and are rotatably connected to the corresponding connecting strips 22;

[0058] like Figure 6As shown, a second driving mechanism for pushing two connecting strips 22 to slide to change the spacing between two groups of fish conveying units is provided in the classification box 1. The second driving mechanism is two electric push rods 23 respectively arranged on the front and rear side walls of the classification box 1. The first driving mechanism includes a dial 24 arranged at the lower end of the roller shaft 21 on the left side of each group of fish conveying units, a rotating rod 25 arranged horizontally in the classification box 1, and a driving element arranged on the side wall of the classification box 1; the driving element is a second motor 26;

[0059] Each of the dials 24 is provided with twelve fixed columns 241, and the rotating rod 25 is fixedly sleeved with two spiral blades 251 corresponding to the dials 24 and meshing with the fixed columns 241. The spiral directions of the two spiral blades 251 are opposite. The left end of the rotating rod 25 passes through the side wall of the classification box 1 and is fixedly connected to the output shaft of the second motor 26.

[0060] Preferably, two laser ranging sensors for measuring the thickness of the fish trunk are provided on the top surface of the classification box 1 on the left side of the two fish conveying units, which are not shown in the figure. The two laser ranging sensors correspond to the positions of the two fish conveying units, and the laser ranging sensors are electrically connected to the PLC controller.

[0061] The working principle of the above-mentioned fish conveying unit is as follows: the second motor 26 can drive the rotating rod 25 to rotate. Since the two spiral blades 251 are engaged with the fixed column 241, the two spiral blades 251 will drive the two dials 24 to rotate in the opposite direction. When the fish enters the fish conveying unit, the two laser ranging sensors respectively measure the distance between the left and right sides of the fish. The total distance between the two laser ranging sensors minus the distance between the laser ranging sensors and the left and right sides of the fish can be used to obtain the thickness of the fish trunk. The PLC controller controls the extension of the electric push rod 23 according to the thickness of the fish trunk. The electric push rod 23 drives the roller 21 to slide through the connecting strip 22 to adjust the distance between the two conveyor belts 2.

[0062] Embodiment 5: This embodiment is basically the same as Embodiment 1, except that the second driving mechanism is a screw rod horizontally arranged in the classification box 1, the screw rod is threadedly connected to the two connecting strips 22, and the thread directions of the left and right sides of the screw rod are opposite, and the right end of the screw rod passes through the right side wall of the classification box 1 and is provided with a driving motor.

[0063] The working principle of the second driving mechanism is as follows: the driving motor can drive the screw rod to rotate, so that the two connecting strips 22 move toward the middle at the same time under the action of the threads.

[0064] Example 6: Figure 7As shown, this embodiment is basically the same as the embodiment 4, except that there is an angle difference of 180° between the rotation angles of the two spiral blades 251, a liquid storage pipe 28 arranged parallel to the rotating rod 25 and used to store the cleaning agent is provided on the front side of the rotating rod 25, a sliding sleeve 27 is provided on the sliding sleeve 27, and a pressurizing device for pressurizing the inside of the liquid storage pipe 28 is provided at the right end of the liquid storage pipe 28, and the pressurizing device adopts a commercially available pressurizing pump; the cleaning agent adopts hydrogen peroxide;

[0065] Two friction columns 271 are arranged in parallel on the side wall of the sliding sleeve 27 between the two spiral blades 251, and are used to contact the two spiral blades 251 alternately to push the sliding sleeve 27 to slide back and forth. Figure 8 As shown, the interior of the sliding sleeve 27 is hollow and a mixing chamber 272 is provided on the side wall. The mixing chamber 272 is communicated with the flushing water pipe 39. The surface of the liquid storage tube 28 located in the moving section of the sliding sleeve 27 is provided with five strip-shaped liquid outlets, and the strip-shaped liquid outlets are provided with sealing plates 281 connected to the strip-shaped liquid outlets by swinging through torsion springs. The sealing plates 281 are rotatably connected to the strip-shaped liquid outlets through a rotating shaft. The torsion spring is sleeved on the rotating shaft. The sealing plates 281 are sealed and connected to the strip-shaped liquid outlets in a horizontal state, and a shifting block is provided on the sealing plate 281. The shifting block is hemispherical. A spring for shifting the shifting block is provided in the sliding sleeve 27. The sealing plate is swung to open the paddle 273 of the strip liquid outlet, and the number of paddles 273 and sealing plates 281 corresponds one to one. Both ends of the sliding sleeve 27 are slidingly and sealingly connected to the liquid storage tube 28, and the sliding sleeve 27 is connected to the mixing chamber 272 through a pressure valve. The pressure valve adopts the existing technology product. It can be understood that there is a cleaning agent inside the sliding sleeve 27. The passing value of the pressure valve is 0.2MPa. When the liquid storage tube 28 is connected to the sliding sleeve 27, the pressure in the sliding sleeve 27 will increase and exceed 0.2MPa; the spacing between the two friction columns 271 is 4cm.

[0066] The working principle of the sliding sleeve 27 is as follows: when the rotating rod 25 rotates, the spiral blade 251 on the left side will first contact the friction column 271 on the left side. As the rotating rod 25 continues to rotate, the spiral blade 251 on the left side will push the friction column 271 on the left side to the right, causing the sliding sleeve 27 to slide to the right, until the spiral blade 251 on the left side separates from the friction column 271 on the left side. At this time, the spiral blade 251 on the right side contacts the friction column 271 on the right side. As the rotating rod 25 continues to rotate, the spiral blade 251 on the right side will push the friction column 271 on the left side to the right side. The rotary blade 251 will push the friction column 271 on the right side to move to the left, causing the sliding sleeve 27 to slide to the left. During the reciprocating sliding of the sliding sleeve 27, the paddle plate 273 will contact the paddle block and push the sealing plate 281 to swing downward, allowing the cleaning agent in the liquid storage tube 28 to enter the sliding sleeve 27 through the strip liquid outlet, and then enter the mixing chamber 272 and mix with the flushing water in the flushing water pipe 39. The sliding sleeve 27 will drive the flushing water pipe 39 to slide back and forth, thereby expanding the flushing range of the flushing water pipe 39.
