Description

Technical Field

[0001] This application relates to the technical field of food processing, and in particular to a fish cutter. Background Technology

[0002] Canned fish is a food processing and preservation technique that refers to processed fish placed in cans and then sealed and heated to produce a food product that is easy to store and carry. Canned fish can be preserved for a long time while maintaining the nutrition and taste of the fish, and is a common form of food.

[0003] When sardines and other fish are made into canned fish, the fish need to be "headed and tailed," that is, the head and tail of the fish need to be cut off, and the remaining fish body is used as the raw material for canned fish. The traditional method of "heading and tailing" fish is mainly done manually, which is inefficient and labor-intensive. Summary of the Invention

[0004] To improve the processing efficiency of canned fish, this application provides a fish cutting machine.

[0005] The fish-cutting machine provided in this application adopts the following technical solution: A fish-cutting machine includes a machine base and a first conveyor belt disposed within the machine base. A head-cutting station and a tail-cutting station are sequentially arranged within the machine base along the conveying direction of the first conveyor belt. The head-cutting station is equipped with a first cutter for cutting off the fish head, and the tail-cutting station is equipped with a second cutter for cutting off the fish tail. An alignment strip is provided on one side edge of the first conveyor belt. The machine base is equipped with a pushing assembly for pushing the fish head on the first conveyor belt to abut against the alignment strip so that the first cutter can cut it.

[0006] By adopting the above technical solution, the fish are placed on the first conveyor belt for conveying through the first cutter, the second cutter, and the pushing component. The heads of the fish are all facing one side of the alignment strip. During the conveying process, the pushing component pushes the fish so that the heads of the fish abut against the alignment strip. The alignment strip can position the fish and keep it within the set position range during the conveying process. This allows the first cutter to cut off the head of the fish when it is conveyed to the head-cutting station. When it is conveyed to the tail-cutting station, the second cutter can cut off the tail, thereby realizing the "head and tail removal" of the fish and greatly improving the processing efficiency of canned fish.

[0007] Optionally, the machine is provided with an adsorption station located between the head-cutting station and the tail-cutting station; the adsorption station is provided with an adsorption box located on one side of the first conveyor belt, the adsorption box has an adsorption cavity, and the side wall of the adsorption box near the first conveyor belt has an adsorption hole communicating with the adsorption cavity; the adsorption box is connected to a negative pressure adsorption component for extracting air from the adsorption cavity.

[0008] By adopting the above technical solution, the adsorption station is set between the head-cutting station and the tail-cutting station through the setting of the adsorption box and the negative pressure adsorption component. When the fish head is cut off by the first cutter, the fish intestines are exposed and continue to be conveyed to the adsorption station. The negative pressure adsorption component is used to remove the air in the adsorption chamber, so that the adsorption chamber forms a negative pressure. At this time, when the fish passes the adsorption box and approaches the side wall of the first conveyor belt, the adsorption holes can suck out the fish intestines, so as to facilitate the subsequent production of canned fish and improve production efficiency.

[0009] Optionally, the negative pressure adsorption assembly includes a vacuum pump, a first negative pressure tank, a second negative pressure tank, and a switching component. The input end of the vacuum pump is connected to the outlet end of the first negative pressure tank. Two second negative pressure tanks are provided, and the outlet ends of both second negative pressure tanks are connected to the inlet ends of the first negative pressure tank. The inlet ends of both second negative pressure tanks are connected to the adsorption chamber of the adsorption box. The switching component is disposed between the two second negative pressure tanks to switch the opening and closing of the two second negative pressure tanks.

[0010] By adopting the above technical solution, through the configuration of a vacuum pump, a first negative pressure tank, a second negative pressure tank, and a switching mechanism, during operation, the vacuum pump is activated, and the air in the adsorption chamber is sequentially drawn away through the second and first negative pressure tanks to extract the fish intestines. After the fish intestines are extracted, the second negative pressure tank can collect them uniformly. By setting up two second negative pressure tanks, switching can be performed when one of the tanks has collected a certain amount of fish intestines, improving work efficiency and reducing the possibility of downtime. In addition, the first negative pressure tank is set between the vacuum pump and the second negative pressure tank, serving as a "second line of defense" to further collect fish and water, reducing the possibility of fish intestines or water being directly drawn to the vacuum pump.

[0011] Optionally, the surface of the first conveyor belt is provided with multiple partitions, which are arranged at intervals around the first conveyor belt, and a partition area for fish to embed is formed between two adjacent partitions; a second conveyor belt is provided inside the machine, and the first and second conveyor belts are arranged side by side, with the outlet end of the first conveyor belt facing the inlet end of the second conveyor belt; the first conveyor belt is provided with a transfer device for transferring the fish body to the second conveyor belt; the machine is provided with multiple saw blades, all of which are located on the second conveyor belt for segmenting the fish body.

[0012] By adopting the above technical solution, and through the setting of the second conveyor belt, the fish, after being "headed and tailed," are transferred to the second conveyor belt via a transfer device. The fish are then segmented by saw blades on the second conveyor belt, thus dividing the fish body into multiple segments for subsequent canning. During the "heading and tailing" process, there are often scraps and fish intestines adhering to the first conveyor belt. By separately setting up the second conveyor belt (separating the "heading and tailing" process from the segmentation of the fish body), the fish body needed for canning can be separated out individually, minimizing the possibility of fish intestines or scraps from the "heading and tailing" process entering the next processing step, thereby improving the overall production efficiency.

[0013] Optionally, the pushing assembly includes a rotating shaft, a pusher, and a rotating motor. The rotating shaft is rotatably connected to the machine base and located on the first conveyor belt. The pusher is disposed on the outer peripheral wall of the rotating shaft and is spirally wound along the central axis of the rotating shaft. One end of the pusher forms a first pushing surface for pushing fish. The rotating motor is disposed on the machine base, and the output shaft of the rotating motor is connected to the rotating shaft.

[0014] By adopting the above technical solution, through the arrangement of the rotating shaft, push wheel, and rotating motor, during the fish conveying process, the rotating motor drives the rotating shaft to rotate, which in turn drives the push wheel to rotate around the central axis of the rotating shaft. This allows the first pushing surface to push the fish on the first conveyor belt and push the fish's head to the alignment strip so that the first cutter can cut off the fish head. The push wheel is set in a spiral shape, which to a certain extent guides and limits the speed, so that the first pushing surface can push the fish.

[0015] Optionally, the pushing assembly includes a sliding plate, a pushing block, and a driving component. The sliding plate is slidably mounted on the machine base and located on the first conveyor belt. The bottom wall of the sliding plate has multiple lifting slots. Multiple pushing blocks are provided and are correspondingly arranged in the multiple lifting slots. Each pushing block is slidably mounted in the corresponding lifting slot. The pushing block has a second pushing surface for pushing fish. A return spring is provided between the pushing block and the corresponding lifting slot. The return spring normally forces the second pushing surface of the pushing block to abut against the fish. The driving component is provided on the sliding plate to drive the sliding plate to move along the width direction of the first conveyor belt.

[0016] By adopting the above technical solution, through the arrangement of the sliding plate, pushing block, and driving component, after the fish are conveyed to the area below the sliding plate, the sliding plate is driven to move towards the side closer to the alignment bar. The pushing block of the sliding plate can push the fish to abut against the alignment bar. Multiple pushing blocks can enable the sliding plate to push multiple fish simultaneously, improving the efficiency of fish alignment. On the other hand, through the arrangement of the return spring and lifting groove, when the distance between multiple fish and the alignment bar is different, as the sliding plate moves towards the alignment bar, the fish that are closer to the alignment bar contact the alignment bar first. Under the obstruction of the alignment bar, the pushing block can move into the lifting groove (i.e., this pushing block can no longer push the corresponding fish), continuing to drive the sliding plate to move towards the alignment bar. The fish that are farther away can then contact the alignment bar. The effect achieved is that even when the distance between multiple fish and the alignment bar is different, after one movement of the sliding plate, multiple fish can abut against the alignment bar, improving work efficiency.

[0017] Optionally, the driving component includes a drive shaft, an arc-shaped rack, a first rack, a second rack, and a drive motor. The drive shaft is rotatably connected to the machine base and located on the first conveyor belt. The arc-shaped rack is disposed on the outer peripheral wall of the drive shaft. The first rack and the second rack are both disposed on a sliding plate. Both ends of the first rack and the second rack extend along the width direction of the first conveyor belt. The first rack and the second rack are symmetrically distributed around the axial direction of the drive shaft. The drive motor is disposed on the machine base, and the output shaft of the drive motor is connected to the drive shaft. When the drive shaft rotates, forcing the arc-shaped rack to mesh with the first rack, the sliding plate moves closer to the alignment strip. When the drive shaft rotates, forcing the arc-shaped rack to mesh with the second rack, the sliding plate moves away from the alignment strip.

[0018] By adopting the above technical solution, through the arrangement of the drive shaft, the arc-shaped rack, the first rack, the second rack, and the drive motor, the drive shaft drives the arc-shaped rack to rotate around the central axis of the drive shaft, forcing the arc-shaped rack to mesh with the first rack. At this time, the sliding plate moves closer to the alignment bar, thereby pushing the fish to the alignment bar to abut. As the drive shaft continues to rotate, the arc-shaped rack disengages from the first rack and meshes with the second rack. At this time, the sliding plate can move away from the alignment bar to reset, so as to push the next fish. This achieves the reciprocating movement of the sliding plate, thereby continuously pushing the fish and improving the work efficiency.

[0019] Optionally, the first cutter is slidably mounted on the machine and can be raised and lowered. The side wall of the alignment strip near the first conveyor belt has a first through groove for the fish head to pass through. A support block is installed in the first through groove. The top wall of the support block has a support surface and a guide surface. The support surface is used to support the fish head. The cut fish head is discharged outward from the guide surface.

[0020] By adopting the above technical solution, and through the setting of the support block, after the fish is pushed to the alignment bar, the head of the fish enters the first through groove. Since the size of the fish body is larger than the size of the fish head, the fish head stops moving forward after entering the first through groove. At this time, the support surface of the support block can support the fish head so that the first cutter can cut it off. The cut fish head flows out under the action of the guide surface, thereby collecting the fish head and improving the working efficiency of the overall structure.

[0021] Optionally, the inner wall of the first through-groove is provided with a first limiting groove, and a limiting piece is slidably installed in the first limiting groove. The support block is slidably installed in the first through-groove, and the side wall of the support block is provided with a second limiting groove. The support block is provided with a first spring, and the first spring, in its normal state, causes the second limiting groove to face the limiting piece, and the support surface of the support block supports the fish head. The limiting piece is provided with a second spring, and the second spring, in its normal state, forces the limiting piece to partially move out of the first limiting groove and into the second limiting groove. The first cutter is provided with an unlocking and unloading component. When the first cutter moves down to cut the fish head and continues to move down, the unlocking and unloading component forces the limiting piece to disengage from the second limiting groove and the support block to move down.

[0022] By adopting the above technical solution, through the setting of the limiting plate, the first spring and the second spring, under normal conditions (when the fish head is inserted into the first through groove and has not been cut off), the limiting plate is inserted into the second limiting groove, thereby limiting the support block and enabling the support block to support the fish head; after the fish head is cut off by the first cutter moving down, the first cutter is driven to move down a certain distance. At this time, the unlocking unloading part can force the limiting plate to disengage from the second limiting groove, so that the support block can move down, so that the cut fish head can slide outward along the guide surface, reducing the possibility that the support block and the inner wall of the first through groove will clamp the cut fish head and cause the cut fish head to stay in the first through groove, thus making it easier for the head of the next fish to enter the first through groove.

[0023] Optionally, the unlocking and unloading component includes an unlocking rod and a unloading block. One end of the unlocking rod is connected to a first cutter. The top wall of the alignment strip has a connecting hole that connects to a first limiting groove for the unlocking rod to pass through. The top wall of the limiting plate has a second through groove for the unlocking rod to pass through. The inner wall of the second through groove forms an unlocking surface. When the unlocking rod passes through the second through groove, the unlocking rod pushes the unlocking surface and forces the limiting plate to disengage from the second limiting groove. One end of the unloading block is connected to a support block, and the other end extends into the first limiting groove. The unloading block is located below the limiting plate for the unlocking rod to push.

[0024] By adopting the above technical solution, through the setting of the unlocking rod and the feeding block, after the first cutter cuts off the fish head by moving down, it continues to drive the first cutter to move down a certain distance. At this time, the unlocking rod enters the first limiting groove and pushes the limiting piece through the unlocking surface, causing the limiting piece to disengage from the second limiting groove, releasing the limiting of the support block. The first cutter continues to move down, and at this time, the unlocking rod can push the feeding block, forcing the support block to move down, thereby expanding the first through groove, so that the cut fish head can slide outward under its own weight. This reduces the possibility that the support surface of the support block and the inner wall of the first through groove will clamp the fish head, preventing the fish head from sliding out, and improves the practicality of the overall structure.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Fish are placed on a first conveyor belt and transported by a first cutter, a second cutter, and a pushing component, with the heads of the fish all facing the alignment strip. During transport, the pushing component pushes the fish so that their heads abut against the alignment strip. The alignment strip positions the fish and keeps them within a set range during transport, so that when the fish are transported to the head-cutting station, the first cutter can cut off the head; and when they are transported to the tail-cutting station, the second cutter can cut off the tail, thus achieving the "head and tail removal" of the fish and greatly improving the processing efficiency of canned fish. 2. Through the arrangement of the sliding plate, pushing block, and driving component, after the fish are conveyed to the area below the sliding plate, the sliding plate is driven to move towards the alignment bar. The pushing block of the sliding plate can push the fish to abut against the alignment bar. Multiple pushing blocks can allow the sliding plate to push multiple fish simultaneously, improving the efficiency of fish alignment. On the other hand, through the arrangement of the return spring and lifting groove, when the distance between multiple fish and the alignment bar is different, as the sliding plate moves towards the alignment bar, the fish that are closer to the alignment bar contact the alignment bar first. Due to the obstruction of the alignment bar, the pushing block can move into the lifting groove (i.e., this pushing block can no longer push the corresponding fish), and continue to drive the sliding plate to move towards the alignment bar. The fish that are farther away can then contact the alignment bar. The effect achieved is that even when the distance between multiple fish and the alignment bar is different, after one movement of the sliding plate, multiple fish can abut against the alignment bar, improving work efficiency. 3. With the setting of the limiting plate, the first spring and the second spring, under normal conditions (when the fish head is inserted into the first through groove and has not been cut off), the limiting plate is inserted into the second limiting groove, thereby limiting the support block and enabling the support block to support the fish head; after the fish head is cut off by the first cutter moving down, the first cutter is driven to move down a certain distance. At this time, the unlocking of the feeding part can force the limiting plate to disengage from the second limiting groove, so that the support block can move down, so that the cut fish head can slide outward along the guide surface, reducing the possibility that the support block and the inner wall of the first through groove will clamp the cut fish head and cause the cut fish head to stay in the first through groove, thus making it easier for the head of the next fish to enter the first through groove.

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 12 This application will be described in further detail.

[0029] Example 1: This application discloses a fish cutter.

[0030] Reference Figure 1 , Figure 2 A fish-cutting machine includes a machine base 1 and a first conveyor belt 2 installed inside the machine base 1. In this embodiment, a plurality of partitions 22 are fixedly installed on the outer surface of the first conveyor belt 2. The plurality of partitions 22 are arranged at intervals around the conveying direction of the first conveyor belt 2. Both ends of each partition 22 extend along the width direction of the conveyor belt. A partition area 221 is formed between two adjacent partitions 22. The partition area 221 is used for fish (mainly sardines) to be embedded. It should be noted that the distance between the side wall of the partition 22 away from the surface of the first conveyor belt 2 and the surface of the first conveyor belt 2 is less than the thickness of the fish. That is, after the fish is placed in the partition area 221, part of the fish is exposed outside the partition area 221.

[0031] Reference Figure 1 , Figure 2 Multiple pressure plates 16 are installed on the inner wall of the machine 1. The multiple pressure plates 16 are arranged at intervals along the conveying direction of the first conveyor belt 2. The pressure plates 16 are set horizontally and are located above the first conveyor belt 2. The pressure plates 16 are spaced apart from the surface of the first conveyor belt 2 to allow fish to pass through. The pressure plates 16 are used to limit the fish and reduce the possibility of the fish leaving the separation area 221 during the conveying process.

[0032] Reference Figure 1 , Figure 2 The machine tool 1 is equipped with a head-cutting station 11 and a tail-cutting station 12, which are arranged sequentially along the conveying direction of the first conveyor belt 2. The head-cutting station 11 is equipped with a first cutter 111 for cutting off the fish head, and the tail-cutting station 12 is equipped with a second cutter 121 for cutting off the fish tail. In this embodiment, both the first cutter 111 and the second cutter 121 are circular in shape. Both the first cutter 111 and the second cutter 121 are rotatably mounted on the inner wall of the machine tool 1. A first motor (not shown in the figure) is mounted on the inner wall of the machine tool 1 and is fixedly mounted on the side wall of the machine tool 1. The output shaft of the first motor is coaxially fixed to the first cutter 111 to drive the first cutter 111 to rotate around its own central axis. A second motor (not shown in the figure) is mounted on the inner wall of the machine tool 1 and is fixedly mounted on the side wall of the machine tool 1. The output shaft of the second motor is coaxially fixed to the second cutter 121 to drive the second cutter 121 to rotate around its own central axis.

[0033] Reference Figure 1 , Figure 2 The machine 1 is equipped with an alignment strip 21 on its inner wall. The alignment strip 21 is located on one side edge of the first conveyor belt 2. Both ends of the alignment strip 21 extend along the length of the first conveyor belt 2. The machine 1 is equipped with a pushing component 3, which is used to push the fish head on the first conveyor belt 2 to abut against the alignment strip 21 so that the first cutter 111 can cut it.

[0034] Reference Figure 2 , Figure 3 In this embodiment, the pushing component 3 includes a rotating shaft 31, a pusher 32, and a rotating motor. The rotating shaft 31 is rotatably connected to the inner wall of the machine base 1. The axial direction of the rotating shaft 31 is consistent with the conveying direction of the first conveyor belt 2. The rotating shaft 31 is located above the first conveyor belt 2, and the rotating shaft 31 is located on the side of the head cutting station 11 away from the tail cutting station 12.

[0035] The pusher 32 is fixedly installed on the outer peripheral wall of the rotating shaft 31. In this embodiment, the pusher 32 is spirally wound along the central axis of the rotating shaft 31. The end of the pusher 32 near the cutting station 11 forms a first pushing surface 321. When the fish is conveyed to the bottom of the rotating shaft 31 by the first conveyor belt 2 and the rotating shaft 31 rotates, the first pushing surface 321 pushes the fish so that the head of the fish abuts against the alignment strip 21. The rotating motor (not shown in the figure) is fixedly installed on the side wall of the machine base 1. The output shaft of the rotating motor is connected to the rotating shaft 31 to drive the rotating shaft 31 to rotate around its own central axis. In this embodiment, the output shaft of the rotating motor and the rotating shaft 31 are connected by a reducer.

[0036] Reference Figure 1 , Figure 2 The inner wall of the machine 1 is equipped with a baffle 24. The baffle 24 is located on the side of the first conveyor belt 2 away from the alignment strip 21, and the baffle 24 is located at the tail cutting station 12. The two ends of the baffle 24 extend along the length of the first conveyor belt 2. The machine 1 is equipped with a translation component 8, which is used to push the fish toward the baffle 24 so that the second cutter 121 can cut off the fish tail.

[0037] Reference Figure 1 , Figure 2 In this embodiment, a water storage tank 17 is installed inside the machine base 1. The translation component 8 includes a first water supply pipe 81 and a first nozzle 82. The first water supply pipe 81 is installed on the inner wall of the machine base 1 and is located on the side of the first conveyor belt 2 away from the baffle 24. Both ends of the first water supply pipe 81 extend along the conveying direction of the first conveyor belt 2. Multiple first nozzles 82 are provided and are arranged at intervals along the length direction of the first water supply pipe 81. Each first nozzle 82 is installed on the periphery of the first water supply pipe 81 and communicates with the interior of the first water supply pipe 81. Each first nozzle 82 faces the baffle 24. A first connecting pipe (not shown in the figure) connects the first water supply pipe 81 to the water storage tank 17. The first water supply pipe 81 is connected to the water storage tank 17 through the first connecting pipe. A water pump 171 is installed in the water storage chamber.

[0038] Reference Figure 1 , Figure 2 The machine 1 is equipped with a second conveyor belt 5, which is arranged in parallel with the first conveyor belt 2. The outlet end of the first conveyor belt 2 is directly opposite the inlet end of the second conveyor belt 5. The machine 1 is rotatably equipped with multiple saw blades 15, which are all located above the second conveyor belt 5 for segmenting the fish body. The first conveyor belt 2 is equipped with a transfer component 6 for transferring the fish body to the second conveyor belt 5.

[0039] Reference Figure 1 , Figure 2The transfer component 6 includes a second water supply pipe 61 and a second nozzle 62. The second water supply pipe 61 is installed on the inner wall of the machine base 1 and is located on the side of the first conveyor belt 2 away from the baffle 24. Both ends of the second water supply pipe 61 extend along the conveying direction of the first conveyor belt 2. Multiple second nozzles 62 are provided and are arranged at intervals along the length of the second water supply pipe 61. Each second nozzle 62 is installed on the periphery of the second water supply pipe 61 and connects to the interior of the second water supply pipe 61. Each second nozzle 62 faces the inlet end of the second conveyor belt 5. A second connecting pipe (not shown in the figure) connects the second water supply pipe 61 to the water storage tank 17. The second water supply pipe 61 is connected to the water storage tank 17 through the second connecting pipe.

[0040] The implementation principle of Embodiment 1 of this application is as follows: fish are placed on the first conveyor belt 2 for conveying, and the heads of the fish are uniformly facing the side of the alignment strip 21. During the conveying process, the rotating shaft 31 is driven to rotate, and the push wheel 32 can push the fish body so that the fish head abuts against the alignment strip 21. The alignment strip 21 can position the fish so that it is kept within the set position range during the conveying process, so that when the fish is conveyed to the head cutting station 11, the first cutter 111 can cut off the fish head.

[0041] The fish is then transported to the tail-cutting station 12, where the first nozzle 82 sprays water towards one side of the baffle 24, pushing the fish towards the baffle 24 so that the second cutter 121 can cut off the fish's tail, thus achieving the "head and tail removal" of the fish and greatly improving the processing efficiency of canned fish.

[0042] Example 2: This application discloses a fish cutter.

[0043] Reference Figure 4 The difference between the fish cutter disclosed in this application and Embodiment 1 is that: In this embodiment, the push wheel 32 is fixedly installed on the outer peripheral wall of the rotating shaft 31. The shape of the push wheel 32 is set as a cam. When the push wheel 32 rotates around the central axis of the rotating shaft 31, the outer peripheral wall of the push wheel 32 can push the fish body so that the fish head abuts against the side wall of the alignment strip 21.

[0044] Example 3: This application discloses a fish cutter.

[0045] Reference Figure 5 , Figure 6 The difference between the fish cutter disclosed in this application and Embodiment 1 is that: In this embodiment, an adsorption station 13 is provided inside the machine 1. The adsorption station 13 is located between the head cutting station 11 and the tail cutting station 12. An adsorption box 14 is installed inside the adsorption station 13. The adsorption box 14 is located on the side of the first conveyor belt 2 away from the baffle 24. The adsorption box 14 is hollow inside and forms an adsorption cavity 141. The side wall of the adsorption box 14 near the first conveyor belt 2 is flush with the side wall of the alignment strip 21 near the first conveyor belt 2. The side wall of the adsorption box 14 near the first conveyor belt 2 has multiple adsorption holes 142 that communicate with the adsorption cavity 141.

[0046] Reference Figure 5 , Figure 7 The adsorption box 14 is connected to a negative pressure adsorption assembly 4 for extracting air from the adsorption chamber 141. The negative pressure adsorption assembly 4 includes a vacuum pump, a first negative pressure tank 41, a second negative pressure tank 42, and a switching component 43. A first connecting pipe 411 connects the vacuum pump (not shown in the figure) to the first negative pressure tank 41. One end of the first connecting pipe 411 is connected to the input end of the vacuum pump, and the other end is connected to the inside of the first negative pressure tank 41. The input end of the vacuum pump and the outlet end of the first negative pressure tank 41 are connected through the first connecting pipe 411. There are two second negative pressure tanks 42. Both second negative pressure tanks 42 are connected to a second connecting pipe 421. One end of the second connecting pipe 421 is connected to the inside of the second negative pressure tank 42, and the other end is connected to the first negative pressure tank 41. The outlet ends of both second negative pressure tanks 42 are connected to the inlet end of the first negative pressure tank 41 through the second connecting pipe 421.

[0047] The bottom wall of the adsorption box 14 is connected to a third connecting pipe 143, and both second negative pressure tanks 42 are connected to a fourth connecting pipe 422. One end of the fourth connecting pipe 422 connects to the inside of the second negative pressure tank 42, and the other end connects to the third connecting pipe 143. The second negative pressure tanks 42 and the adsorption chamber 141 are interconnected through the third connecting pipe 143 and the fourth connecting pipe 422. It should be noted that in this embodiment, filter screens (not shown in the figure) are installed in the inlet end of the first connecting pipe 411 and the inlet end of the second connecting pipe 421. The filter screens are used to intercept fish intestines.

[0048] Reference Figure 7 The switching element 43 is disposed between the two second negative pressure tanks 42 to switch the opening and closing of the two second negative pressure tanks 42. In this embodiment, the switching element 43 includes four opening and closing valves, two of which are respectively installed on the two second connecting pipes 421, and the other two are respectively installed on the two fourth connecting pipes 422.

[0049] Reference Figure 7The bottom walls of the two second negative pressure tanks 42 are connected to discharge pipes 423, which are used to discharge fish intestines and water. The top walls of the two second negative pressure tanks 42 are connected to third water supply pipes 424, one end of which is connected to the inside of the second negative pressure tank 42, and the other end is connected to the water storage tank 17.

[0050] The implementation principle of Embodiment 3 of this application is as follows: The adsorption station 13 is set between the head-cutting station 11 and the tail-cutting station 12. When the fish head is cut off by the first cutter 111, the fish intestines are exposed and continue to be conveyed to the adsorption station 13. The negative pressure adsorption component 4 is used to remove the air in the adsorption chamber 141, so that the adsorption chamber 141 forms a negative pressure. At this time, when the fish passes through the adsorption box 14 and approaches the side wall of the first conveyor belt 2, the adsorption hole 142 can suck out the fish intestines, so as to facilitate the subsequent production of canned fish and improve production efficiency.

[0051] During operation, the vacuum pump is activated, and the air in the adsorption chamber 141 is sequentially drawn away by the vacuum pump through the second negative pressure tank 42 and the first negative pressure tank 41 to extract the fish intestines. After the fish intestines are extracted, the second negative pressure tank 42 can collect them uniformly. By setting up two second negative pressure tanks 42, the system can switch over after one tank has collected a certain amount of fish intestines, improving work efficiency and reducing the possibility of downtime. In addition, the first negative pressure tank 41 is set between the vacuum pump and the second negative pressure tank 42. The first negative pressure tank 41 acts as a "second line of defense" to further collect fish and water, reducing the possibility of fish intestines or water being directly drawn to the vacuum pump.

[0052] Example 4: This application discloses a fish cutter.

[0053] Reference Figure 8 , Figure 9 , Figure 10 The difference between the fish cutter disclosed in this application and Embodiment 1 is that: In this embodiment, the pushing component 3 includes a sliding plate 33, a pushing block 34, and a driving component. The sliding plate 33 is horizontally arranged and is slidably installed on the machine base 1 and located on the first conveyor belt 2. The sliding plate 33 can be displaced along the width direction of the first conveyor belt 2. The bottom wall of the sliding plate 33 is provided with a plurality of lifting grooves 331, which are arranged at intervals along the length direction of the first conveyor belt 2. The number of pushing blocks 34 corresponds to the number of lifting grooves 331, and each pushing block 34 is slidably installed in the corresponding lifting groove 331 so as to be able to lift.

[0054] Reference Figure 9 , Figure 10The push block 34 has a second push surface 341 for pushing the fish toward the alignment strip 21. A return spring 342 is provided between the push block 34 and the corresponding lifting groove 331. One end of the return spring 342 is fixedly connected to the inner wall of the lifting groove 331, and the other end is fixedly connected to the push block 34. The return spring 342 normally forces the second push surface 341 of the push block 34 to abut against the fish. It should be noted that in this embodiment, the friction between the fish and the surface of the first conveyor belt 2 is less than the elastic force of the return spring 342, so that the push block 34 can push the fish, and when the head of the fish abuts against the alignment strip 21, the push block 34 can be lifted.

[0055] Reference Figure 9 , Figure 10 A driving component is disposed on the sliding plate 33 to drive the sliding plate 33 to move along the width direction of the first conveyor belt 2. The driving component includes a driving shaft 35, an arc-shaped rack 36, a first rack 37, a second rack 38, and a driving motor. The driving shaft 35 is rotatably connected to the inner wall of the machine base 1. The axial direction of the driving shaft 35 is consistent with the conveying direction of the first conveyor belt 2. The driving shaft 35 is located above the first conveyor belt 2 and is located in the cutting station 11. A mounting frame 332 is fixedly installed on the top wall of the sliding plate 33. One end of the driving shaft 35 extends into the mounting frame 332 and is connected to the arc-shaped rack 36. The arc-shaped rack 36 is arranged in an arc shape around the central axis of the driving shaft 35.

[0056] Reference Figure 9 , Figure 10 The first rack 37 and the second rack 38 are both fixedly installed in the mounting frame 332. Both ends of the first rack 37 and the second rack 38 extend along the width direction of the first conveyor belt 2. The first rack 37 and the second rack 38 are symmetrically distributed around the axial direction of the drive shaft 35. The drive motor (not shown in the figure) is fixedly installed on the side wall of the machine base 1. The output shaft of the drive motor is connected to the drive shaft 35. In this embodiment, the output shaft of the drive motor and the drive shaft 35 are connected by a reducer. When the drive shaft 35 rotates and forces the arc-shaped rack 36 to mesh with the first rack 37, the sliding plate 33 moves closer to the alignment strip 21. When the drive shaft 35 rotates and forces the arc-shaped rack 36 to mesh with the second rack 38, the sliding plate 33 moves away from the alignment strip 21.

[0057] Reference Figure 8 In this embodiment, the first cutter 111 is elongated, and the length direction of the first cutter 111 is consistent with the length direction of the first conveyor belt 2. The machine base 1 is equipped with a lifting cylinder 18 for driving the first cutter 111 to rise and fall. The cylinder body of the lifting cylinder 18 is fixedly installed on the top wall of the machine base 1, and the piston rod of the lifting cylinder 18 is fixedly connected to the top wall of the first cutter 111.

[0058] Reference Figure 8 , Figure 11 The alignment strip 21 has a first through groove 211 for the fish head to pass through on the side wall near the first conveyor belt 2. The number of first through grooves 211 corresponds to the number of push blocks 34. A support block 23 is installed in the first through groove 211. The top wall of the support block 23 has a support surface 231 and a guide surface 232. The support surface 231 is used to support the fish head. The cut fish head is led outward from the guide surface 232.

[0059] The implementation principle of Embodiment 4 of this application is as follows: after the fish are transported to the bottom of the sliding plate 33, the sliding plate 33 is driven to move towards the side close to the alignment bar 21. The pushing block 34 of the sliding plate 33 can push the fish to abut against the alignment bar 21. Multiple pushing blocks 34 can enable the sliding plate 33 to push multiple fish at the same time, thereby improving the efficiency of fish alignment. On the other hand, by setting the return spring 342 and the lifting groove 331, when the distance between multiple fish and the alignment bar 21 is different, as the sliding plate 33 moves toward the alignment bar 21, the fish that are closer to the alignment bar 21 will contact the alignment bar 21 first. Under the obstruction of the alignment bar 21, the pushing block 34 can move into the lifting groove 331 (that is, the pushing block 34 can no longer push the corresponding fish), and continue to drive the sliding plate 33 to move toward the alignment bar 21. The fish that are farther away can contact the alignment bar 21. The effect achieved is that even when the distance between multiple fish and the alignment bar 21 is different, after one action of the sliding plate 33, multiple fish can abut against the alignment bar 21, thus improving work efficiency.

[0060] Example 5: This application discloses a fish cutter.

[0061] Reference Figure 12 The difference between the fish cutter disclosed in this application and embodiment 4 is that: In this embodiment, a first limiting groove 212 is provided on the inner wall of the first through groove 211. A limiting piece 213 is installed in the first limiting groove 212. The limiting piece 213 is slidably installed in the first limiting groove 212 and can move closer to or further away from the first through groove 211 in the horizontal direction. A support block 23 is slidably installed in the first through groove 211 and can be raised and lowered. A second limiting groove 233 is provided on the side wall of the support block 23 near the first limiting groove 212. A first spring 234 is installed on the support block 23. One end of the first spring 234 is fixedly connected to the bottom wall of the support block 23, and the other end is fixedly connected to the bottom wall of the first through groove 211. The first spring 234 normally keeps the second limiting groove 233 facing the limiting piece 213, and the support surface 231 of the support block 23 supports the fish head.

[0062] The limiting piece 213 is equipped with a second spring 214. One end of the second spring 214 is fixedly connected to the side wall of the limiting piece 213, and the other end is fixedly connected to the inner wall of the first limiting groove 212. The second spring 214 normally causes the limiting piece 213 to partially move out of the first limiting groove 212 and insert into the second limiting groove 233.

[0063] Reference Figure 12 The first cutter 111 is equipped with an unlocking feeding component 7. When the first cutter 111 moves down to cut the fish head and continues to move down, the unlocking feeding component 7 forces the limiting piece 213 to disengage from the second limiting groove 233. The unlocking feeding component 7 includes an unlocking rod 71 and a feeding block 72. The unlocking rod 71 is vertically arranged, and the upper end of the unlocking rod 71 is fixedly connected to the first cutter 111. The top wall of the alignment strip 21 has a connecting hole 215, which connects to the first limiting groove 212 for the unlocking rod 71 to pass through. The top wall of the limiting piece 213 has a second through groove 216 for the unlocking rod 71 to pass through. The inner wall of the second through groove 216 forms an unlocking surface 217. When the unlocking rod 71 passes through the second through groove 216, the unlocking rod 71 pushes the unlocking surface 217 and forces the limiting piece 213 to disengage from the second limiting groove 233.

[0064] Reference Figure 12 One end of the feeding block 72 is fixedly connected to the side wall of the support block 23, and the other end extends into the first limiting groove 212. The feeding block 72 is located below the limiting piece 213 so that the unlocking rod 71 can push it.

[0065] The implementation principle of Embodiment 5 of this application is as follows: Under normal conditions (when the fish head is inserted into the first through-groove 211 and has not been cut off), the limiting piece 213 is inserted into the second limiting groove 233, thereby limiting the support block 23 so that the support block 23 can support the fish head; after the fish head is cut off by the first cutter 111 moving down, the first cutter 111 is driven to move down a certain distance. At this time, the unlocking rod 71 enters the first limiting groove 212 and pushes the limiting piece 213 through the unlocking surface 217. The limiting piece 213 is disengaged from the second limiting groove 233, releasing the limiting effect on the support block 23; the first cutter 111 continues to move downward, at which time the unlocking rod 71 can push the feeding block 72, forcing the support block 23 to move downward, thereby expanding the first through groove 211, so that the cut fish head can slide outward along the guide surface 232 under its own weight, reducing the possibility that the support surface 231 of the support block 23 and the inner wall of the first through groove 211 will clamp the fish head and prevent it from sliding out.

[0066] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
