Description

Technical Field

[0001] This invention belongs to the field of canned food production and packaging, and more specifically, relates to a canning equipment and canning method for canned fish. Background Technology

[0002] In the current fish canning process, the removal of the head and tail of the fish is often done by machine, which is fast. However, the canning process is often done manually, with the fish meat being stuffed into the cans. This is inefficient, as manual processing cannot keep up with the speed of machine processing. As a result, there are often piles of processed fish meat, leading to low production efficiency. In order to increase the canning speed, factories hire more workers for manual canning, which increases the required labor force and labor costs, thus raising production costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a canning equipment and canning method for canned fish, which can realize automated canning of fish on an assembly line, automatically adjust the weight of fish meat in the can according to standards, and achieve high canning efficiency and low production cost.

[0004] The present invention provides a canning device for fish cans, comprising a canning mechanism;

[0005] The canning mechanism includes a discharge pipe;

[0006] The discharge pipe is a tube open at both ends. The upper end of the discharge pipe receives fish meat, and the lower end discharges fish meat. The discharge pipe is equipped with an inlet mechanism and an outlet mechanism. The inlet mechanism is located above the outlet mechanism, and a metering chamber is provided between the inlet and outlet mechanisms. The size of the metering chamber is designed to hold only a certain amount of fish meat. The inlet mechanism is sized to close the discharge pipe and is rotatably connected to the inner wall of the discharge pipe. The outlet mechanism is also sized to close the discharge pipe and is rotatably connected to the inner wall of the discharge pipe. The inlet and outlet mechanisms are linked so that opening the outlet mechanism controls closing the inlet mechanism.

[0007] As a further improvement of the present invention, the size of the quantitative chamber is such that a certain amount of fish meat can be placed, and there is a gap between the fish meat at the top and the inlet mechanism. The gap allows the inlet mechanism to rotate while touching the surface of the fish meat at the top. The inlet mechanism can only rotate in the direction of the closed discharge pipe while touching the fish meat.

[0008] As a further improvement of the present invention, the inlet mechanism includes an upper fixed plate and an upper rotating plate. One side of the upper fixed plate is fixedly connected to the inner wall of the discharge pipe; one side of the upper rotating plate is rotatably connected to the inner wall of the discharge pipe, so that the other side of the upper rotating plate can rotate around the line connecting it to the discharge pipe; the side of the upper fixed plate near the upper rotating plate is disposed above the upper rotating plate; the sum of the maximum distance from the side of the upper fixed plate connected to the discharge pipe to the other side of the fixed plate and the maximum distance from the side of the upper rotating plate connected to the discharge pipe to the other side is greater than the diameter of the discharge pipe, so that the upper fixed plate can abut against the upper rotating plate; an elastic rod is fixedly connected to the lower side of the upper fixed plate. The elastic rod is elastic, one end of the elastic rod is fixedly connected to the lower surface of the upper rotating plate, and the other end of the elastic rod is fixedly connected to the inner wall of the discharge pipe; when the upper rotating plate is in a horizontal state, the elastic rod is in a free state.

[0009] As a further improvement of the present invention, the outlet mechanism includes a rotating plate and an associated component; the rotating plate closes the lower side of the metering chamber, one side of the rotating plate is rotatably connected to the inner wall of the discharge pipe, and the rotating plate can rotate up and down around the connection line between it and the discharge pipe as an axis; and the outer diameter of the rotating plate is equal to the inner diameter of the discharge pipe, so that when the rotating plate is in a horizontal state, the other side of the rotating plate is in close contact with the inner wall of the discharge pipe, and the rotating plate can close the lower side of the metering chamber; a driving component is provided on the lower side of the rotating plate, and the driving component controls the movement of the rotating plate around the axis; the associated component connects the rotating plate and the inlet mechanism, so that the opening of the rotating plate controls the closing of the inlet mechanism.

[0010] As a further improvement of the present invention, a sliding groove is provided on one side of the discharge pipe, the long axis of the sliding groove is in the up-down direction, and the sliding groove connects the inside of the discharge pipe with the outside; the associated component includes a connecting rod, which is disposed in the sliding groove and is V-shaped. One end of the connecting rod passes through the sliding groove and is fixedly connected to the rotating plate, so that the rotation of the rotating plate will drive the rotation of the connecting rod; the other end of the connecting rod is disposed at the upper part of the sliding groove, so that when the rotating plate rotates downward, the connecting rod rotates upward, so that the upper end of the connecting rod moves toward the inside of the discharge pipe until it abuts against the lower bottom surface of the upper rotating plate.

[0011] As a further improvement of the present invention, the drive assembly includes a return rod, one end of which is fixedly connected to the bottom surface of the rotating plate, and the other end of which is fixedly connected to the inner wall of the discharge pipe; the return rod is elastic, and the elastic coefficient of the return rod is the elastic coefficient that restricts the rotating plate from rotating downward under a certain gravity.

[0012] As a further improvement of the present invention, the driving assembly also includes an electromagnet, which is disposed on the lower side of the rotating shaft of the rotating plate and is fixedly connected to the inner wall of the discharge pipe; the electromagnet generates magnetism when energized.

[0013] As a further improvement of the present invention, a partitioning component is provided in the quantitative chamber, and the number of partitioning components plus one is equal to the number of fish meat that can be contained in the quantitative chamber; the multi-part partitioning component divides the quantitative chamber into multiple sub-chambers, the number of sub-chambers is equal to the number of fish meat that can be contained, and the volume of each sub-chamber is only allowed to contain one piece of fish meat.

[0014] As a further improvement of the present invention, the number of partition components is two sets, each set of partition components includes a rotating plate and a fixed plate; one side of the fixed plate is fixedly connected to the inner wall of the discharge pipe so that the other side of the fixed plate is fixed; one side of the rotating plate is rotatably connected to the inner wall of the discharge pipe so that the other side of the rotating plate can rotate about the line connecting it to the discharge pipe as an axis; the other side of the rotating plate is disposed below the fixed plate so that the rotating plate abuts against the fixed plate in the horizontal state; an elastic rod is disposed on the lower side of each rotating plate, the elastic rod is elastic, one end of the elastic rod is fixedly connected to the lower bottom surface of the rotating plate, and the other end of the elastic rod is fixedly connected to the inner wall of the discharge pipe; and when the rotating plate is in the horizontal state, the elastic rod is in the free state.

[0015] A canning method for a canning equipment for fish cans, characterized in that: S1: empty fish cans are transported to the lower side of the two outlets of the discharge pipe;

[0016] S2: Fish meat of similar size and weight enters the discharge pipe from the storage box. The upper rotating plate rotates downward, the inlet mechanism opens, and the fish meat enters the quantitative chamber.

[0017] S3: After a certain amount of fish meat enters the quantitative chamber, the inlet mechanism comes into contact with the fish meat to prevent the inlet mechanism from rotating downwards, and the inlet mechanism seals the upper side of the quantitative chamber.

[0018] S4: Control the outlet mechanism to rotate downwards. While the lower side of the metering chamber opens, the outlet mechanism controls the inlet mechanism to remain closed, so that the fish meat on the upper side of the outlet mechanism cannot enter the metering chamber, and the fish meat in the metering chamber enters the empty fish can.

[0019] S5: The canned fish containing fish meat is transported away, and the empty canned fish is transported to the lower side of the second outlet of the discharge pipe.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: it limits the amount of fish meat in the quantitative chamber and links the inlet mechanism and the outlet mechanism so that the outlet mechanism opens to control the inlet mechanism to close. This setting allows the outlet mechanism to open and the inlet mechanism to close when the fish meat in the quantitative chamber enters the fish can, so as to prevent excess fish meat from entering the quantitative chamber. This ensures that the amount of fish meat entering the fish can from the quantitative chamber each time is constant, thereby realizing automated quantitative filling of fish meat in the fish can. The machine operates automatically at high speed, with high efficiency and low cost, reducing the production cost of fish cans.

[0021] An electromagnet is installed on the lower side of the rotating plate so that after the rotating plate rotates downward under the gravity of the three pieces of fish meat, the electromagnet attracts and fixes the rotating plate so that when there is fish meat falling down from the upper side of the rotating plate, the return rod cannot drive the rotating plate back to its original position, thus ensuring that all three pieces of fish meat in the metering chamber fall out, and preventing the outlet mechanism from closing before all the fish meat in the metering chamber is discharged.

[0022] The partitioning component divides the metering chamber into multiple sub-chambers so that each sub-chamber contains exactly one piece of fish meat during operation. This improves the accuracy of the amount of fish meat contained in the metering chamber and prevents the number of fish meat in the metering chamber from exceeding the required amount due to the deformability of the fish meat, thus improving the accuracy of canning.

[0037] Explanation of the labels in the diagram:

[0038] The can filling mechanism includes: 1. Storage box; 11. Discharge pipe; 12. Electromagnet; 13. Fixed plate; 121. Rotating plate; 122. Elastic rod; 123. Rotating plate; 124. Return rod; 1241. Connecting rod; 125. Sliding groove; 127. Detailed Implementation

[0039] Specific Implementation Example 1: Please refer to Figure 1-9 A canning equipment for fish cans, including a canning mechanism 1.

[0040] The canning mechanism 1 is connected to a fish processing line at its inlet. The canning mechanism 1 is used to receive fish meat of similar size and weight after the head and tail have been removed from the fish meat processed by the line, and to automatically pack the fish meat into fish cans in a certain quantity or quality.

[0041] The canning mechanism 1 includes a storage bin 11 and a discharge pipe 12.

[0042] The storage bin 11 has an internal chamber for receiving fish meat processed by the production line. The upper end of the storage bin 11 has a fish meat inlet that is connected to the outlet of the production line so that the fish meat on the production line enters the internal chamber of the storage bin 11 through the fish meat inlet. The lower end of the storage bin 11 has a fish meat outlet that connects the internal chamber of the storage bin 11 to the outside of the storage bin 11. During operation, after the fish meat enters the chamber through the fish meat inlet, it falls out from the fish meat outlet from top to bottom due to gravity.

[0043] The discharge pipe 12 is a tube that is open at both the top and bottom. The upper end of the discharge pipe 12 is fixedly connected to the fish meat outlet. The discharge pipe 12 is connected to the inside of the storage box 11 through the fish meat outlet so that the fish meat in the storage box 11 enters the discharge pipe 12 through the fish meat outlet.

[0044] A sliding groove 127 is provided on one side of the discharge pipe 12. The sliding groove 127 is a full groove on one side of the discharge pipe 12. The long axis of the sliding groove 127 is in the up-down direction. The sliding groove 127 connects the inside of the discharge pipe 12 with the outside, so that objects can be extended from the outside into the inside of the discharge pipe 12 through the sliding groove 127.

[0045] The discharge pipe 12 is equipped with an inlet mechanism and an outlet mechanism inside;

[0046] The inlet mechanism is located below the fish meat outlet and above the outlet mechanism. In the free state, the inlet mechanism closes the channel at the top of the discharge pipe 12. The inlet mechanism includes a fixed plate 121 and a rotating plate 122.

[0047] One side of the fixing plate 121 is fixedly connected to the inner wall of the discharge pipe 12, and the other side of the fixing plate 121 is provided with an upper abutment plate. The upper surface of the upper abutment plate is at the same level as the upper surface of the fixing plate 121, and the lower surface of the upper abutment plate is higher than the lower surface of the fixing plate 121.

[0048] One side of the rotating plate 122 is rotatably connected to the inner wall of the discharge pipe 12, so that the other side of the rotating plate 122 can rotate around the line connecting it to the discharge pipe 12; the size of the rotating plate 122 is such that at least one piece of fish meat can pass through after the rotating plate 122 rotates.

[0049] An elastic rod 123 is fixedly connected to the lower side of the rotating plate 122. The elastic rod 123 is elastic, one end of the elastic rod 123 is fixedly connected to the lower surface of the rotating plate 122, and the other end of the elastic rod 123 is fixedly connected to the inner wall of the discharge pipe 12. When the rotating plate 122 is in a horizontal state, the elastic rod 123 is in a free state, so that after the rotating plate 122 rotates, the elastic rod 123 generates an elastic restoring force to drive the rotating plate 122 to reset.

[0050] A lower abutment plate is provided on the left side of the rotating plate 121. The lower surface of the lower abutment plate is at the same horizontal plane as the lower surface of the rotating plate 122 in the free state. The upper surface of the lower abutment plate is at the same height as the lower surface of the upper abutment plate, so that when the rotating plate 121 is in the free state, the upper surface of the lower abutment plate is in contact with the lower surface of the upper abutment plate. Since the fixed plate 121 cannot rotate, the rotating plate 122 is restricted to rotating clockwise around the axis to the horizontal height.

[0051] It should be noted that the sum of the maximum distance from the right side of the fixed plate 121 to the left inner wall of the discharge pipe 12 and the maximum distance from the left side of the rotating plate 122 to the right inner wall of the discharge pipe 12 should be greater than the diameter of the discharge pipe 12 so that the upper abutment plate can abut against the lower abutment plate.

[0052] The export mechanism includes a rotating plate 124 and a connecting rod 125;

[0053] A rotating plate 124 is disposed on the lower side of the inlet mechanism. A magnetically conductive metal is disposed on the lower bottom surface of the rotating plate 124 so that the rotating plate 124 can be attracted by a magnet. One side of the rotating plate 124 is rotatably connected to the inner wall of the discharge pipe 12 so that the other side of the rotating plate 124 can rotate up and down around the connection line between it and the discharge pipe 12. The outer diameter of the rotating plate 124 is equal to the diameter of the discharge pipe 12 so that when the rotating plate 124 is in a horizontal state, the other side of the rotating plate 124 is in close contact with the inner wall of the discharge pipe 12, and the rotating plate 124 can close the discharge pipe 12.

[0054] The connecting rod 125 is made of rigid material and is disposed in the sliding groove 127. The connecting rod 125 is V-shaped. One end of the connecting rod 125 passes through the sliding groove 127 and is fixedly connected to the rotating plate 124 so that the rotation of the rotating plate 124 will drive the rotation of the connecting rod 125. The other end of the connecting rod 125 is disposed at the upper part of the sliding groove 127. When the rotating plate 124 rotates downward, the connecting rod 125 rotates upward so that the upper end of the connecting rod 125 moves toward the inside of the discharge pipe 12 until it abuts against the bottom surface of the rotating plate 121.

[0055] A gravity sensor is provided on the upper surface of the rotating plate 124. The gravity sensor detects whether the upper surface of the rotating plate 124 is subjected to pressure, and outputs the detected result in the form of an electrical signal.

[0056] A return rod 1241 is provided on the lower side of the rotating plate 124. One end of the return rod 1241 is fixedly connected to the bottom surface of the rotating plate 124, and the other end of the return rod 1241 is fixedly connected to the inner wall of the discharge pipe 12. The return rod 1241 is elastic so that after the rotating plate 124 rotates downward, the return rod 1241 provides an elastic restoring force to the rotating plate 124. The elastic coefficient of the return rod 1241 is limited so that only when the gravity on the rotating plate 124 is greater than or equal to the gravity of three pieces of fish meat, will the gravity on the rotating plate 124 be greater than the elastic coefficient of the return rod 1241, so that the rotating plate 124 rotates downward and the outlet mechanism is opened.

[0057] An electromagnet 13 is provided on the lower side of the rotating plate 124. The electromagnet 13 is fixedly connected to the inner wall of the discharge pipe 12. When the rotating plate 124 rotates downward and the left end of the rotating plate 124 rotates to the lower right, the electromagnet 13 is located on the inner wall of the right side of the discharge pipe 12. The electromagnet 13 generates magnetism when energized.

[0058] It should be noted that, due to the screening and processing on the assembly line, the fish meat that finally enters the storage bin 11 has a similar size and weight. Since the required standard quantity in the fish can is three pieces of fish meat, the space between the inlet and outlet mechanisms is designed to only allow for the placement of three pieces of fish meat. A gap exists between the top piece of fish meat and the inlet mechanism, allowing the rotating plate 122 to rotate against the surface of the top piece of fish meat. Furthermore, the fish meat content in the can only meet the standard when all three pieces of fish meat are of sufficient weight. If at least one piece of fish meat is underweight, the fish meat content in the can will be insufficient and needs to be replenished. Therefore...

[0059] A conveying channel is provided on the lower side of the discharge pipe 12. The conveying channel is used to transport empty fish cans to the lower side of the outlet of the discharge pipe 12, and then transport fish cans containing a fixed amount of fish meat to the next step.

[0060] The outlet of the transmission channel is connected to the inlet of the adjustment channel. An adjustment box is set on the upper side of the adjustment channel. The adjustment box contains fish meat fragments. The mass and size of the fish meat fragments are smaller than the mass and size of the fish meat in the storage box 11. The fish meat fragments are caused by machine processing errors during the production process, resulting in the fish meat being incompletely cut, which makes it not meet the standard for entering the storage box 11. After the fish meat is processed into fragments, it enters the adjustment box to supplement the weight of the canned food that is underweight.

[0061] The lower end of the adjustment box is provided with an adjustment outlet, which is located on the upper side of the adjustment channel so that the fish meat fragments in the adjustment box can enter the fish meat can on the adjustment channel through the adjustment outlet;

[0062] A gravity sensor is installed at the exit of the transmission channel. The fish cans that have been quantitatively filled are transported by the transmission channel to the upper part of the gravity sensor. The gravity sensor detects the weight of the fish meat inside the fish can and transmits the detected data in the form of an electrical signal.

[0063] The gravity sensor is electrically connected to a control module, which stores the weight range of fish meat in a standard weight can of fish. The control module receives the electrical signal transmitted by the gravity sensor and compares the content of fish meat in the can of fish detected by the gravity sensor with the standard.

[0064] The control module is electrically connected to the gravity sensor and receives electrical signals from the gravity sensor. The control module is also electrically connected to electromagnet 13 and controls the electromagnet 12 to be energized or de-energized. Furthermore, the control module is electrically connected to the adjustment outlet and controls its opening and closing. When the control module determines that the fish meat content in the canned fish meets the standard, it closes the adjustment outlet, and no further replenishment of fish meat is made. When the control module determines that the fish meat content in the canned fish is insufficient, it opens the adjustment outlet, allowing fish meat from the adjustment box to enter the canned fish through the outlet until the fish meat content meets the standard. At this point, the control module closes the adjustment outlet, and the canned fish leaves the adjustment channel. Since the gravity sensor's detection of weight, the control module's determination of the fish meat content in the canned fish, and the control module's control of the adjustment outlet are all existing technologies, they will not be described in detail in this application.

[0065] In the process of quantitative canning of fish, each can contains three pieces of fish meat. Therefore, the canning equipment for fish canning has the following canning method:

[0066] S1: The conveyor channel transports the empty fish cans to the lower side of the outlet of the discharge pipe 12;

[0067] S2: Fish meat of similar size and weight enters the discharge pipe 12 from the storage box 11. The rotating plate 122 rotates downward under the pressure of the fish meat, the inlet mechanism is opened, and the fish meat enters the lower side of the inlet mechanism.

[0068] S3: During the process of the first and second pieces of fish meat entering, the elastic restoring force of the elastic rod 123 attempts to drive the rotating plate 122 to reset. However, due to the pressure of the fish meat on the upper side of the rotating plate 122, the rotating plate 122 always rotates downward. When the third piece of fish meat enters, the lower surface of the third piece of fish meat abuts against the left end of the rotating plate 122. At this time, the rotating plate 122 rotates upward under the action of the elastic restoring force of the elastic rod 123. The lower part of the third piece of fish meat is lifted upward under the action of the rotating plate 122 until the rotating plate 122 resets to the closing exit mechanism. The lower part of the third piece of fish meat returns to the free state, the inlet mechanism is closed, and there are three pieces of fish meat between the inlet mechanism and the outlet mechanism.

[0069] S4: The gravity sensor on the rotating plate 124 senses the gravity acting on the rotating plate 124 and sends an electrical signal to the control module. After receiving the electrical signal, the control module controls the electromagnet 13 to be energized, and the electromagnet 13 generates magnetism. The rotating plate 124 rotates downward under the gravity of the three pieces of fish meat, and the outlet mechanism is opened. At this time, the rotating plate 124 is attracted by the magnetic force of the electromagnet 13 and is fixed to the electromagnet 13. At this time, the lower side of the discharge pipe 12 is opened, and the fish meat between the inlet mechanism and the rotating plate 124 falls from the lower side of the discharge pipe 12 into the empty fish can. At the same time, as the rotating plate 124 rotates downward, it drives the connecting rod 125 to rotate upward. The connecting rod 125 passes through the sliding groove 127 and enters the lower side of the inlet mechanism. The upper end of the connecting rod 125 abuts against the lower bottom surface of the rotating plate 122. As the rotating plate 124 rotates, the rotating plate 122 rotates upward until the upper abutting block abuts against the lower abutting block. At this time, the inlet mechanism is closed.

[0070] S5: The transmission channel transports a can of fish containing three pieces of fish meat to the outlet of the transmission channel. At this time, there is no fish meat between the inlet and outlet mechanisms. The gravity sensor on the rotating plate 124 senses that the rotating plate 124 is not subject to gravity. After receiving the electrical signal from the gravity sensor, the control module controls the electromagnet 13 to be de-energized. The rotating plate 124 returns to a horizontal position under the elastic restoring force of the return rod 1241 to control the outlet mechanism to close. The rotating plate 122 is not abutted by the connecting rod 125, and the rotating plate 122 can be pushed open by the fish meat on the upper side of the inlet mechanism.

[0071] S6: The gravity sensor detects the weight of the fish meat inside the canned fish and sends an electrical signal to the control module. The control module controls the opening and closing of the adjustment outlet based on the received electrical signal. When the control module determines that the canned fish is sufficiently heavy, it closes the adjustment outlet, and the canned fish is transported directly out of the adjustment channel. When the control module determines that the canned fish is underweight, it opens the adjustment outlet. After the canned fish enters the adjustment channel, the adjustment box replenishes the fish meat inside the can until it is sufficiently heavy, and then the canned fish is transported out of the adjustment channel.

[0072] It should be noted that in step S2, even if the rotating plate 122 rotates downward under the force of the fish meat on the upper side of the inlet mechanism, the rotating plate 122 will come into contact with the third piece of fish meat after rotating downward, so as to restrict the rotation of the rotating plate 122. At this time, because the opening of the rotating plate 122 is too small, the fish meat on the upper side of the inlet mechanism is stuck on the upper side of the rotating plate 122, and the fish meat cannot enter the lower side of the rotating plate 122 from the opening of the rotating plate 122. There are always three pieces of fish meat between the inlet mechanism and the outlet mechanism.

[0073] It should be noted that the methods and principles of adjusting the channel for transporting canned fish and controlling the adjustment box for replenishing fish meat in canned fish are existing technologies, and therefore will not be elaborated upon in this application.

[0074] Specific Implementation Example 2: Unlike Specific Implementation Example 1, please refer to... Figure 10-13 There are three fixed plates 121, which are arranged from top to bottom as upper fixed plate, middle fixed plate and lower fixed plate; there are three rotating plates 122, which are arranged from top to bottom as upper rotating plate, middle rotating plate and lower rotating plate.

[0075] A second elastic rod is provided between the middle rotating plate and the lower rotating plate. One end of the second elastic rod is fixedly connected to the lower side of the middle rotating plate, and the other end of the second elastic rod is fixedly connected to the inner wall of the discharge pipe 12. When the middle rotating plate is in a horizontal state, the second elastic rod is in a free state.

[0076] An elastic rod three is provided between the lower rotating plate and the rotating plate 124. One end of the elastic rod three is fixedly connected to the bottom surface of the lower rotating plate, and the other end of the elastic rod three is fixedly connected to the inner wall of the discharge pipe 12. When the lower rotating plate is in a horizontal state, the elastic rod three is in a free state.

[0077] The upper fixed plate and the upper rotating plate form the entrance mechanism. The middle fixed plate and the middle rotating plate, the lower fixed plate and the lower rotating plate divide the space between the entrance mechanism and the rotating plate 124 into three parts. Each part is large enough to hold only one piece of fish meat. There is a gap between the upper surface of the fish meat and the rotating plate 122 or the second rotating plate 141, which allows the rotating plate 122 or the second rotating plate 141 to rotate along the upper surface of the fish meat.

[0078] Working principle: After the first piece of fish meat is pressed against the upper rotating plate, the middle rotating plate and the lower rotating plate respectively, it enters the lowest space between the inlet mechanism and the outlet mechanism. At this time, the end of the lower rotating plate away from the rotation axis is in contact with the lower surface of the fish meat, and the elastic rod connected to the lower rotating plate drives the lower rotating plate to reset. The lower part of the first piece of fish meat is lifted upward by the action of the lower rotating plate and the end that abuts against it until the lower rotating plate resets to abut against the lower fixed plate, and the lower part of the first piece of fish meat returns to the free state.

[0079] When the second piece of fish meat presses against the upper rotating plate and the middle rotating plate respectively and enters between the middle rotating plate and the lower rotating plate, the second piece of fish meat presses the lower rotating plate to rotate downward. However, because the lower rotating plate is in contact with the first piece of fish meat, the second piece of fish meat cannot pass through the lower rotating plate. The second piece of fish meat stays between the middle rotating plate and the lower rotating plate, and the end of the middle rotating plate away from the rotation axis is in contact with the lower surface of the fish meat. The lower part of the second piece of fish meat is lifted upward by the action of the middle rotating plate and the end that is in contact with it until the middle rotating plate returns to its original position and abuts against the middle fixed plate. The lower part of the second piece of fish meat returns to its free state.

[0080] The movement principle of the third piece of fish is the same as that of the first two pieces of fish. The third piece of fish stays in the space between the upper rotating plate and the middle rotating plate. At this time, there are only three pieces of fish in the space between the inlet mechanism and the outlet mechanism.
