Description

Technical Field

[0001] The present application relates to the technical field of food processing, and in particular to a fish cutting machine. Background Art

[0002] Canned fish is a food processing and preservation technology, which refers to the process of putting processed fish into cans, sealing and heating them to make them easy to store and carry. Canned fish can be preserved for a long time and maintain the nutrition and taste of fish, making it a common food form.

[0003] When sardines and other fish are made into canned fish, the fish need to be "clipped off the head and tail", that is, the fish head and tail need to be cut off, and the remaining fish body is used as the raw material for canned fish; the traditional way of "clipping off the head and tail" of fish mainly relies on manual work, which has low processing efficiency and labor-intensive. Summary of the invention

[0004] In order to improve the processing efficiency of canned fish, the present application provides a fish cutter.

[0005] The fish cutting machine provided in this application adopts the following technical solution: A fish cutting machine comprises a machine platform and a first conveyor belt arranged in the machine platform, wherein a head cutting station and a tail cutting station are sequentially arranged in the machine platform along the conveying direction of the first conveyor belt, wherein the head cutting station is provided with a first cutter for cutting off the fish head, and the tail cutting station is provided with a second cutter for cutting off the fish tail; an alignment strip is arranged on one side edge of the first conveyor belt, and the machine platform is provided with a pushing component, wherein the pushing component is used to push the fish head on the first conveyor belt to abut against the alignment strip for cutting by the first cutter.

[0006] By adopting the above technical solution, the fish are placed on the first conveyor belt for conveyance through the arrangement of the first cutter, the second cutter and the pushing component, and the heads of the fish are uniformly oriented to one side of the alignment strip. During the conveying process, the pushing component is used to push the fish so that the heads of the fish abut against the alignment strip. The arrangement of the alignment strip can position the fish so that it remains within the set position range during the conveying process, so that when the fish is conveyed to the head cutting station, the first cutter can cut off the fish head; and continue to convey to the tail cutting station, the second cutter can cut off the fish tail, thereby achieving the "head and tail removal" of the fish, greatly improving the processing efficiency of canned fish.

[0007] Optionally, an adsorption station is provided in the machine, and the adsorption station is 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 close to the first conveyor belt is provided with an adsorption hole connected to 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 scheme, the adsorption station is set between the head cutting station and the tail cutting station through the arrangement of the adsorption box and the negative pressure adsorption component. When the fish head is cut off by the first cutter to expose the fish intestines, it is continuously conveyed to the adsorption station, and the air in the adsorption chamber is extracted by the negative pressure adsorption component to form a negative pressure in the adsorption chamber. At this time, when the fish passes through the side wall of the adsorption box close to the first conveyor belt, the adsorption holes can suck out the fish intestines 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 the two second negative pressure tanks are connected to the inlet end of the first negative pressure tank; the inlet ends of the two second negative pressure tanks are connected to the adsorption chamber of the adsorption box; the switching component is provided between the two second negative pressure tanks for switching the opening and closing of the two second negative pressure tanks.

[0010] By adopting the above-mentioned technical solution, through the setting of the vacuum pump, the first negative pressure tank, the second negative pressure tank and the switching component, when working, start the vacuum pump, and the air in the adsorption chamber can be extracted by the vacuum pump through the second negative pressure tank and the first negative pressure tank in turn to extract the fish intestines. After the fish intestines are extracted, the second negative pressure tank can collect the fish intestines in a unified manner. By setting two second negative pressure tanks, when one of the second negative pressure tanks collects a certain amount of fish intestines, it can be switched to improve work efficiency and reduce the possibility of downtime. In addition, the first negative pressure tank is set between the vacuum pump and the second negative pressure tank. The first negative pressure tank serves as a "second line of defense" to further collect fish and water, reducing the possibility of fish intestines or water being directly extracted to the vacuum pump.

[0011] Optionally, a plurality of partitions are provided on the surface of the first conveyor belt, and the plurality of partitions are arranged at intervals around the first conveyor belt, and a separation area for fish to be embedded is formed between two adjacent partitions; a second conveyor belt is arranged in the machine, and the first conveyor belt and the second conveyor belt are arranged in parallel, and the outlet end of the first conveyor belt is opposite to the inlet end of the second conveyor belt, and the first conveyor belt is provided with a transfer member for transferring the fish body to the second conveyor belt; the machine is provided with a plurality of saw blades, and the plurality of saw blades are all located on the second conveyor belt for segmenting the fish body.

[0012] By adopting the above technical solution and setting up the second conveyor belt, the fish is transferred to the second conveyor belt through the transfer member after being "cut off the head and tail", and is segmented by the saw blade on the second conveyor belt, so that the fish body is divided into multiple sections, so as to facilitate the subsequent production of canned fish. When the fish is "cut off the head and tail", there will be debris, and there will be fish intestines attached to the first conveyor belt. By setting up a second conveyor belt separately (i.e., separating the "cutting off the head and tail" of the fish from the segmentation of the fish body), the fish body required for the production of canned fish can be picked out separately, and the possibility of the fish intestines or debris generated when "cutting off the head and tail" enter the next processing step is reduced as much as possible, thereby improving the production efficiency of the overall structure.

[0013] Optionally, the pushing assembly includes a rotating shaft, a push wheel and a rotating motor, the rotating shaft is rotatably connected to the machine platform and is located on the first conveyor belt, the push wheel is arranged on the outer peripheral wall of the rotating shaft, the push wheel is spirally wound along the central axis of the rotating shaft, and one end of the push wheel forms a first pushing surface for pushing fish; the rotating motor is arranged on the machine platform, and the output shaft of the rotating motor is connected to the rotating shaft.

[0014] By adopting the above technical solution, through the setting of the rotating shaft, the push wheel and the rotating motor, during the conveying process of the fish, the rotating shaft is driven to rotate by the rotating motor, so as to drive the push wheel to rotate around the central axis of the rotating shaft, so that the first pushing surface can push the fish on the first conveyor belt and push the head of the fish to the alignment strip, so that the first cutter can cut off the fish head; the push wheel is set to be spirally wound, and the spiral push wheel plays a guiding speed limiting effect to a certain extent, 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 member, the sliding plate is slidably installed on the machine platform and is located on the first conveyor belt, the bottom wall of the sliding plate is provided with a plurality of lifting grooves, the pushing block is provided with a plurality of lifting grooves and is arranged corresponding to the plurality of lifting grooves, each of the pushing blocks is slidably installed in the corresponding lifting groove; the pushing block has a second pushing surface for pushing fish, a return spring is arranged between the pushing block and the corresponding lifting groove, the return spring normally forces the second pushing surface of the pushing block to abut against the fish; the driving member is arranged 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 setting of the sliding plate, the pushing block and the driving member, after the fish is transported to the bottom of the sliding plate, the sliding plate is driven to move toward the side close to the alignment strip, and the pushing block of the sliding plate can push the fish to abut against the alignment strip, and multiple pushing blocks can enable the sliding plate to push multiple fish at the same time, thereby improving the efficiency of fish alignment. On the other hand, through the setting of the reset spring and the lifting groove, when the spacing between multiple fish and the alignment strip is different, as the sliding plate moves toward the alignment strip, the fish closer to the alignment strip first contacts the alignment strip, and under the obstruction of the alignment strip, the pushing block can move into the lifting groove (that is, the pushing block can no longer push the corresponding fish), and continue to drive the sliding plate to move toward the alignment strip, and the fish farther away can contact the alignment strip, thereby achieving the effect that: even if the spacing between multiple fish and the alignment strip is different, after one action of the sliding plate, multiple fish can abut against the alignment strip, thereby improving work efficiency.

[0017] Optionally, the driving member includes a driving shaft, an arcuate rack, a first rack, a second rack and a driving motor, the driving shaft is rotatably connected to the machine table and is located on the first conveyor belt, the arcuate rack is arranged on the outer peripheral wall of the driving shaft, the first rack and the second rack are both arranged on a sliding plate, both ends of the first rack and the second rack are extended along the width direction of the first conveyor belt, and the first rack and the second rack are symmetrically distributed around the axis of the driving shaft; the driving motor is arranged on the machine table, and the output shaft of the driving motor is connected to the driving shaft, when the driving shaft rotates to force the arcuate rack to engage with the first rack, the sliding plate moves toward the alignment bar, and when the driving shaft rotates to force the arcuate rack to engage with the second rack, the sliding plate moves away from the alignment bar.

[0018] By adopting the above-mentioned technical scheme, 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 toward the alignment bar, thereby pushing the fish to the alignment bar to resist; 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 be reset away from the alignment bar to facilitate pushing the next fish, thereby realizing the reciprocating displacement of the sliding plate, and then the fish can be continuously pushed, thereby improving working efficiency.

[0019] Optionally, the first cutter is slidably installed on the machine and can be raised and lowered, and a first through-groove for the fish head to pass through is opened on the side wall of the alignment strip close to the first conveyor belt, and a support block is installed in the first through-groove, and the top wall of the support block has a supporting surface and a guide surface, respectively, and the supporting surface is used to support the fish head, and the cut fish head is guided outward by the guide surface.

[0020] By adopting the above-mentioned technical solution and setting the support block, after the fish is pushed to the alignment strip, the head of the fish passes through the first penetration groove. Since the size of the fish body is larger than the size of the fish head, the head of the fish stops moving after passing through the first penetration 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, a first limiting groove is formed on the inner wall of the first penetration groove, a limiting plate is slidably installed in the first limiting groove, the support block is slidably installed in the first penetration groove, a second limiting groove is formed on the side wall of the support block, the support block is provided with a first spring, the first spring normally makes the second limiting groove face the limiting plate, and the supporting surface of the support block supports the fish head; the limiting plate is provided with a second spring, the second spring normally forces the limiting plate to partially move out of the first limiting groove and insert into the second limiting groove; the first cutter is provided with an unlocking blanking piece, when the first cutter moves downward to cut off the fish head and continues to move downward, the unlocking blanking piece forces the limiting plate to disengage from the second limiting groove and the support block to move downward.

[0022] By adopting the above-mentioned technical scheme, through the setting of the limiting plate, the first spring and the second spring, under normal conditions (when the fish head penetrates the first penetration groove and is not cut off), the limiting plate is inserted in the second limiting groove, thereby limiting the support block, so that the support block can support the fish head; after the fish head is cut off by moving the first cutter downward, the first cutter is continued to be driven downward by a certain distance. At this time, unlocking the blanking piece can force the limiting plate to disengage from the second limiting groove, so that the support block can move downward, 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 penetration groove will clamp the cut fish head and cause the cut fish head to stay in the first penetration groove, thereby facilitating the head of the next fish to penetrate the first penetration groove.

[0023] Optionally, the unlocking and blanking part includes an unlocking rod and a blanking block, one end of the unlocking rod is connected to the first cutter, and a connecting hole is provided on the top wall of the alignment strip, and the connecting hole is connected to the first limiting groove for the unlocking rod to penetrate; a second through-groove is provided on the top wall of the limiting plate for the unlocking rod to pass through, and an unlocking surface is formed on the inner wall of the second through-groove, and 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 blanking block is connected to the support block, and the other end extends into the first limiting groove, and the blanking block is located below the limiting plate for the unlocking rod to push.

[0024] By adopting the above-mentioned technical scheme, through the setting of the unlocking rod and the blanking block, after the first cutter moves down to cut off the fish head, the first cutter is continued to be driven down a certain distance. At this time, the unlocking rod penetrates into the first limiting groove and pushes the limiting plate through the unlocking surface, so that the limiting plate disengages from the second limiting groove, releases the limit on the support block, and continues to drive the first cutter downward. At this time, the unlocking rod can push the blanking block, forcing the support block to move downward, thereby expanding the first penetration groove, so that the cut fish head can slide outward under the action of its own weight, reducing the possibility of the support surface of the support block and the inner wall of the first penetration groove clamping the fish head and causing the fish head to be unable to slide out, thereby improving the practicality of the overall structure.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the arrangement of the first cutter, the second cutter and the pushing assembly, the fish are placed on the first conveyor belt for conveyance, and the heads of the fish are uniformly directed toward one side of the alignment strip. During the conveyance process, the pushing assembly is used to push the fish so that the heads of the fish are in contact with the alignment strip. The arrangement of the alignment strip can position the fish so that the fish is kept within the set position range during the conveyance process, so that when the fish is conveyed to the head cutting station, the first cutter can cut off the fish head; and when the fish is further conveyed to the tail cutting station, the second cutter can cut off the fish tail, thereby realizing the "head and tail removal" of the fish, which greatly improves the processing efficiency of canned fish; 2. Through the setting of the sliding plate, the pushing block and the driving member, after the fish is transported to the bottom of the sliding plate, the sliding plate is driven to move toward the side close to the alignment bar, and 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 at the same time, thereby improving the efficiency of fish alignment. On the other hand, through the setting of the reset spring and the lifting groove, when the distances between multiple fish and the alignment bar are different, as the sliding plate moves toward the alignment bar, the fish that are closer will first contact the alignment bar, and under the obstruction of the alignment bar, the pushing block can move into the lifting groove (that is, this pushing block can no longer push the corresponding fish), and continue to drive the sliding plate toward the alignment bar, so that the fish that are farther away can contact the alignment bar, thereby achieving the effect that: even if the distances between multiple fish and the alignment bar are different, after one movement of the sliding plate, multiple fish can abut against the alignment bar, thereby improving work efficiency; 3. Through the setting of the limiting plate, the first spring and the second spring, under normal conditions (when the fish head penetrates the first penetration groove and is not cut off), the limiting plate is inserted in the second limiting groove, thereby limiting the support block so that the support block can support the fish head; after the fish head is cut off by moving the first cutter downward, the first cutter is continued to be driven downward for a certain distance. At this time, unlocking the blanking piece can force the limiting plate to disengage from the second limiting groove, so that the support block can move downward, 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 penetration groove will clamp the cut fish head and cause the cut fish head to stay in the first penetration groove, thereby facilitating the head of the next fish to penetrate the first penetration groove.

[0040] The implementation principle of Example 1 of the present application is: the fish are placed on the first conveyor belt 2 for transportation, and the heads of the fish are uniformly facing one side of the alignment strip 21. During the transportation process, the rotating shaft 31 is driven to rotate, and the push wheel 32 can push the body of the fish so that the head of the fish abuts against the alignment strip 21.

A first connecting pipe 411 is connected between the vacuum pump (not shown in the figure) and 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 interior 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; two second negative pressure tanks 42 are provided, and the two second negative pressure tanks 42 are both connected to a second connecting pipe 421. One end of the second connecting pipe 421 is connected to the interior of the second negative pressure tank 42, and the other end is connected to the first negative pressure tank 41. The outlet ends of the two 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 the third connecting pipe 143, and the two second negative pressure tanks 42 are both connected to the fourth connecting pipe 422. One end of the fourth connecting pipe 422 is connected to the inside of the second negative pressure tank 42, and the other end is connected to the third connecting pipe 143. The second negative pressure tank 42 and the adsorption chamber 141 are connected to each other through the third connecting pipe 143 and the fourth connecting pipe 422. It should be noted that in this embodiment, a filter (not shown in the figure) is installed in the inlet end of the first connecting pipe 411 and the inlet end of the second connecting pipe 421, and the filter is used to intercept fish intestines.

[0048] Reference Figure 7 The switching member 43 is arranged 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 member 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 with a discharge pipe 423, which is used to discharge fish intestines and water to the outside; the top walls of the two second negative pressure tanks 42 are connected with a third water pipe 424, one end of the third water pipe 424 is connected to the interior of the second negative pressure tank 42, and the other end is connected to the water tank 17.

[0050] The implementation principle of Example 3 of the present application is as follows: the adsorption station 13 is set between the head cutting station 11 and the tail cutting station 12, and when the fish head is cut off by the first cutter 111 to expose the fish intestines, the fish intestines are continuously conveyed to the adsorption station 13, and the air in the adsorption chamber 141 is extracted by the negative pressure adsorption component 4 to form a negative pressure in the adsorption chamber 141. At this time, when the fish passes through the adsorption box 14 close to the side wall of the first conveyor belt 2, the adsorption hole 142 can suck out the fish intestines to facilitate the subsequent production of canned fish and improve production efficiency.

[0051] During operation, the vacuum pump is started, and the air in the adsorption chamber 141 can be evacuated by the vacuum pump through the second negative pressure tank 42 and the first negative pressure tank 41 in sequence to extract the fish intestines. After the fish intestines are extracted, the second negative pressure tank 42 can collect the fish intestines uniformly. By setting two second negative pressure tanks 42, when one of the second negative pressure tanks 42 collects a certain amount of fish intestines, it can be switched to improve work efficiency and reduce 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 serves as a "second line of defense" to further collect fish and water, reducing the possibility of fish intestines or water being directly extracted to the vacuum pump.

[0052] Embodiment 4: The embodiment of the present application discloses a fish cutter.

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

[0054] Reference Fig. 9 , Fig.10The pushing block 34 has a second pushing surface 341 for pushing the fish toward the alignment strip 21. A return spring 342 is arranged between the pushing 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 pushing block 34. The return spring 342 normally forces the second pushing surface 341 of the pushing block 34 to abut against the fish. It should be noted that in this embodiment, the friction force 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 pushing block 34 can push the fish, and when the head of the fish abuts against the alignment strip 21, the pushing block 34 can be lifted.

[0055] Reference Fig. 9 , Fig.10 The driving member is arranged 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 member 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 table 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 the driving shaft 35 is located in the head 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, and the arc-shaped rack 36 is arranged in an arc shape around the central axis of the driving shaft 35.

[0056] Reference Fig. 9 , Fig.10 The first rack 37 and the second rack 38 are both fixedly installed in the installation frame 332, and both ends of the first rack 37 and the second rack 38 are extended along the width direction of the first conveyor belt 2, and 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 1, and the output shaft of the drive motor is connected to the drive shaft 35. In this embodiment, the output shaft of the drive motor is connected to the drive shaft 35 through a reducer; when the drive shaft 35 rotates to force the arc-shaped rack 36 to engage with the first rack 37, the sliding plate 33 moves toward the alignment bar 21, and when the drive shaft 35 rotates to force the arc-shaped rack 36 to engage with the second rack 38, the sliding plate 33 moves away from the alignment bar 21.

[0057] Reference Figure 8 In this embodiment, the shape of the first cutter 111 is set to be a long strip, and the length direction of the first cutter 111 is consistent with the length direction of the first conveyor belt 2; the machine platform 1 is equipped with a lifting cylinder 18 for driving the first cutter 111 to rise and fall, and the cylinder body of the lifting cylinder 18 is fixedly installed on the top wall of the machine platform 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 , Fig.11 A first penetration groove 211 for the fish head to pass through is opened on the side wall of the alignment strip 21 close to the first conveyor belt 2, and the number of the first penetration grooves 211 is arranged corresponding to the number of the pushing blocks 34; a support block 23 is installed in the first penetration groove 211, and the top wall of the support block 23 has a support surface 231 and a guide surface 232 respectively, the support surface 231 is used to support the fish head, and the cut fish head is guided outward by the guide surface 232.

[0059] The implementation principle of Example 4 of the present application is: after the fish is transported to the bottom of the sliding plate 33, the sliding plate 33 is driven to move toward the side close to the alignment bar 21, and the pushing block 34 of the sliding plate 33 can push the fish to collide with 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, through the arrangement of the return spring 342 and the lifting groove 331, when the distances between multiple fish and the alignment strip 21 are different, as the sliding plate 33 moves toward the alignment strip 21, the fish that are closer will first contact the alignment strip 21, and then, under the obstruction of the alignment strip 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 strip 21, and the fish that are farther away can contact the alignment strip 21, thereby achieving the effect that: even if the distances between multiple fish and the alignment strip 21 are different, after one movement of the sliding plate 33, multiple fish can abut against the alignment strip 21, thereby improving work efficiency.

[0060] Embodiment 5: The embodiment of the present application discloses a fish cutter.

[0061] Reference Fig.12 The difference between the fish cutter disclosed in the embodiment of the present application and the embodiment 4 is that: In this embodiment, a first limiting groove 212 is provided on the inner wall of the first penetration groove 211, and a limiting plate 213 is installed in the first limiting groove 212. The limiting plate 213 is slidably installed in the first limiting groove 212 and can approach or move away from the first penetration groove 211 in the horizontal direction; the support block 23 is slidably installed in the first penetration groove 211 and can be lifted and lowered, and a second limiting groove 233 is provided on the side wall of the support block 23 close to the first limiting groove 212. The support block 23 is installed with a first spring 234, 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 penetration groove 211. The first spring 234 normally makes the second limiting groove 233 face the limiting plate 213, and the supporting surface 231 of the support block 23 supports the fish head.

[0062] The limiting plate 213 is installed with a second spring 214, one end of the second spring 214 is fixedly connected to the side wall of the limiting plate 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 plate 213 to partially move out of the first limiting groove 212 and insert into the second limiting groove 233.

[0063] Reference Fig.12 The first cutting knife 111 is provided with an unlocking blanking piece 7. When the first cutting knife 111 moves downward to cut off the fish head and continues to move downward, the unlocking blanking piece 7 forces the limiting piece 213 to disengage from the second limiting groove 233; the unlocking blanking piece 7 includes an unlocking rod 71 and a blanking block 72. The unlocking rod 71 is vertically arranged, and the upper end of the unlocking rod 71 is fixedly connected to the first cutting knife 111; a connecting hole 215 is provided on the top wall of the alignment strip 21, and the connecting hole 215 is connected to the first limiting groove 212 for the unlocking rod 71 to penetrate. The top wall of the limiting piece 213 is provided with a second penetration groove 216 for the unlocking rod 71 to pass through. The inner wall of the second penetration groove 216 forms an unlocking surface 217. When the unlocking rod 71 passes through the second penetration 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 Fig.12 One end of the material removal 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 , and the material removal block 72 is located below the limiting piece 213 for the unlocking rod 71 to push.

[0065] The implementation principle of the fifth embodiment of the present application is as follows: in the normal state (when the fish head penetrates the first penetration groove 211 and is not 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 first cutter 111 moves downward to cut off the fish head, the first cutter 111 is driven to move downward a certain distance, and the unlocking rod 71 penetrates the first limiting groove 212 and pushes the limiting piece 213 through the unlocking surface 217. The limiting plate 213 is disengaged from the second limiting groove 233 to release the limiting on the support block 23; the first cutter 111 is continued to be driven downward, and the unlocking rod 71 can push the blanking block 72 at this time, forcing the support block 23 to move downward, thereby expanding the first penetration groove 211, so that the cut fish head can slide outward along the guide surface 232 under the action of its own weight, reducing the possibility of the support surface 231 of the support block 23 and the inner wall of the first penetration groove 211 clamping the fish head and preventing the fish head from sliding out.

[0066] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
