Description

Technical Field

[0001] This utility model relates to the technical field of saline injection, and in particular to an injection machine for fish. Background Technology

[0002] A brine injector is used to inject brine into meat for thorough marinating. After the meat pieces are injected with the prepared aqueous solution, the meat becomes tender and soft, which can improve the quality and yield of meat products.

[0003] Conventional brine injectors simply inject brine into meat pieces using needles and other mechanisms. However, this process presents several problems. For example, a significant amount of brine leaks onto the injector's worktable during injection, resulting in substantial waste. Furthermore, when injecting fish, the meat tissue is more porous and prone to tearing compared to other meats like beef and pork. Therefore, the insertion and withdrawal of the needle during needle insertion and withdrawal further tears the fish meat, producing more meat flakes. Conventional brine injectors cannot recover the lost brine. Even if they have a basic recovery function, it's ineffective at recovering brine mixed with meat flakes. Therefore, there is an urgent need to develop an injector specifically for fish to address these issues. Utility Model Content

[0004] In view of this, the present invention aims to provide an injection machine for fish, which filters meat particles mixed in the brine through a roller during brine recovery, so as to effectively recover the brine.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An injection machine for fish includes an injection head, a drive mechanism for moving the injection head, a conveyor platform located below the injection head, a liquid storage tank communicating with the injection head, and a recovery device, wherein the injection head faces the conveyor platform and the conveyor platform has a first recovery tank.

[0007] The recycling device includes a rotating roller and a second recycling box located at the front end of the filter of the roller. The roller is used to filter the recycled material in the second recycling box, and the surface of the roller is provided with a plurality of filter holes.

[0008] The first recycling tank is connected to the second recycling tank, and the liquid storage tank has a recycling port located below the roller.

[0009] Furthermore, the injection head is provided with multiple injection needles, one end of which is connected to the injection head and the other end of which faces the delivery table.

[0010] Furthermore, the conveyor platform includes a base and a conveyor belt, the conveyor belt being rotatably mounted on the base via a rotating shaft, and the first recycling bin being located below the conveyor belt.

[0011] Furthermore, it also includes a negative pressure section, through which the liquid storage tank is connected to the injection head.

[0012] Furthermore, the drive mechanism includes a drive motor and a ball screw located above the conveyor table. The output shaft of the drive motor is connected to the lead screw of the ball screw, and the nut of the ball screw is connected to the injection head via a connecting rod.

[0013] Furthermore, it also includes a pressure plate, which is connected to the connecting rod. The pressure plate has multiple through holes through which the injection needle passes.

[0014] Furthermore, the injection head has a base, and a connecting rod is provided between the pressure plate and the base. The bottom end of the connecting rod slides through the base and is fixedly connected to the pressure plate. A stop block is fixedly connected to the upper part of the connecting rod.

[0015] Furthermore, the second recycling bin has an outlet, the edge of which is in contact with the surface of the roller.

[0016] Furthermore, it also includes a detachable third recovery box located at the filter rear end of the roller, the third recovery box having an opening located below the roller.

[0017] Furthermore, the filter rear end of the roller is provided with a scraper, one end of which abuts against the surface of the roller, and the other end is inclined downward and positioned above the opening of the third recycling box.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] This invention uses a drive mechanism to move the injection head to the meat block. The liquid in the storage tank is then injected into the meat block through the injection head. After the liquid flows onto the operating table, it is filtered by a roller to mix with the meat mince. The injected liquid is then recovered through a first recovery tank and a second recovery tank. The filtered liquid is returned to the storage tank for injection. This design effectively recovers the liquid that flows onto the operating table, improves the utilization rate of the recovered liquid, and avoids waste. Attached Figure Description

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] This embodiment relates to an injection machine for fish, one exemplary structure of which is as follows: Figure 1-7 As shown.

[0035] Overall, such as Figure 1 , 2 As shown in Figure 4, the injection machine for fish includes an injection head 1, a drive mechanism for moving the injection head 1, a conveyor platform located below the injection head 1, a liquid storage tank 2 communicating with the injection head 1, and a recovery device. The injection head 1 faces the conveyor platform, which has a first recovery tank 3.

[0036] Specifically, such as Figure 3 and 5 As shown, the recycling device includes a rotating roller 4 and a second recycling box 5 located at the filter front end of the roller 4. The roller 4 is used to filter the recycled material in the second recycling box 5, and the surface of the roller 4 is provided with multiple filter holes 6. The first recycling box 3 and the second recycling box 5 are connected. The liquid storage tank 2 has a recycling port 7 located below the roller 4. The first recycling box 3 has an outlet on its side, and the second recycling box 5 has an inlet on its top. A slide plate 24 is installed on the outlet, as shown in the figure, and the second recycling box 5 is located below the slide plate 24. Therefore, when there is accumulated liquid in the first recycling box 3, it will flow out through the outlet and slide into the second recycling box 5 through the slide plate 24. The roller 4 is mounted on the frame 21 via a rotating shaft and is driven to rotate by a reducer 22. The structure of the filter holes 6 is as follows... Figure 7As shown, the filter hole 6 has a very small aperture, which can block meat scraps.

[0037] In this embodiment, the conveyor platform includes a base 9 and a conveyor belt 10. The conveyor belt 10 is rotatably mounted on the base 9 via a rotating shaft, and the first recycling bin 3 is located below the conveyor belt 10. The conveyor belt 10 is driven to rotate by a first motor 23.

[0038] In addition, such as Figure 4 As shown, the injection head 1 is equipped with multiple injection needles 8. One end of each injection needle 8 is connected to the injection head 1, and the other end faces the conveyor table. Preferably, the injection needles 8 are perpendicular to the conveyor table, that is, the injection needles 8 are perpendicular to the upper surface of the conveyor belt 10, so that the injection needles 8 can better inject the meat pieces.

[0039] In this embodiment, as Figure 6 As shown, it also includes a negative pressure section 26. The liquid storage tank 2 is connected to the injection head 1 through the negative pressure section 26. The negative pressure section 26 is preferably a negative pressure pump. The inlet pipe of the negative pressure pump is inserted into the liquid storage tank 2 and contacts the bottom of the liquid storage tank 2. The outlet pipe of the negative pressure pump is connected to the pipeline on the injection head 1. In this way, the liquid in the liquid storage tank 2 can be better injected into the injection needle 8.

[0040] As an exemplary structure of the drive mechanism, it includes a drive motor 11 and a ball screw 12 disposed above the conveyor table. The output shaft of the drive motor 11 is connected to the lead screw of the ball screw 12, and the nut of the ball screw 12 is connected to the injection head 1 via a connecting rod 17. Preferably, the drive motor 11 is a servo motor. The forward and reverse rotation of the drive motor 11 controls the forward or reverse rotation of the lead screw of the ball screw 12, thereby controlling the up and down movement of the injection head 1 via the nut of the ball screw 12. Simultaneously, the nut of the ball screw 12 and the connecting rod 17 are connected by a connecting plate 27.

[0041] In this embodiment, a pressure plate 13 is also included. The pressure plate 13 is connected to the connecting rod 17. The pressure plate 13 has multiple through holes 14 through which the injection needle 8 passes. When the injection head 1 moves up and down, the pressure plate 13 can be moved up and down simultaneously by the connecting rod 17. When the injection head 1 and the pressure plate 13 move down simultaneously, the pressure plate 13 can hold down the meat when the injection needle 8 is about to pierce the meat, making it easier for the injection needle 8 to be stably and accurately pierced into the meat.

[0042] In addition, the injection head 1 has a base 16, and a connecting rod 25 is provided between the pressure plate 13 and the base 16. The bottom end of the connecting rod 25 slides through the base 16 and is fixedly connected to the pressure plate 13. A stop block 15 is fixedly connected to the upper part of the connecting rod 25. With this arrangement, when the connecting rod 17 carries the injection head 1 upward, the pressure plate 13 can be moved upward by the action of the stop block 15 and the base 16, thereby freeing up space on the conveyor belt 10 for subsequent meat pieces to be conveyed to the area below the injection needle 8.

[0043] In this embodiment, the second recycling bin 5 is provided with an outlet 18, the edge of which is in contact with the surface of the roller 4. By having the edge of the outlet 18 contact the surface of the roller 4, the second recycling bin 5 can maximize the contact between the mixture of brine and minced meat and the surface of the roller 4, thereby better filtering the mixture through the roller 4.

[0044] Additionally, this embodiment includes a detachable third collection box 19 located at the rear end of the filter of the roller 4. The third collection box 19 has an opening located below the roller 4. A scraper 20 is provided at the rear end of the filter of the roller 4. One end of the scraper 20 abuts against the surface of the roller 4, and the other end is inclined downward and positioned above the opening of the third collection box 19. The meat scraps filtered on the roller 4 fall into the third collection box 19 through the opening. The third collection box 19 collects the filtered meat scrapes and, when the roller 4 rotates, scrapes the surface of the roller 4 to prevent the meat scrapes from sticking to the surface of the roller 4.

[0045] This embodiment also includes a control unit, which contains a microcontroller to process various signals. The drive motor 11, reducer 22, first motor 23, and negative pressure pump are all connected to the control unit, thereby controlling the start / stop of the drive motor 11, reducer 22, first motor 23, and negative pressure pump.

[0046] The working process of this embodiment is as follows:

[0047] First, the motor of conveyor belt 10 is started to make it rotate continuously. The meat piece is placed on the conveyor belt 10, and the conveyor belt 10 transports the meat piece to below the injection needle 8. Then, the drive motor 11 of the drive mechanism is started. The output shaft of the drive motor 11 drives the lead screw of the ball screw 12 to rotate. The nut of the ball screw 12 carries the injection head 1 downward. During the downward movement of the injection head 1, the pressure plate 13 first contacts the meat piece and presses it down by its own weight. Then, the injection needle 8 on the injection head 1 passes through the through hole 14 on the pressure plate 13 and inserts into the meat piece. Next, the negative pressure unit 26 is started to draw the brine in the storage tank 2 into the injection head 1 through the pipeline, and then injects it into the meat piece through the injection needle 8.

[0048] After injection by needle 8, drive motor 11 is reversed, and then the ball screw 12 carries injection head 1 upward, causing needle 8 to detach from the meat block. During this detachment, pressure plate 13 maintains its own weight to hold the meat block in place, facilitating needle detachment. After detachment, connecting rod 17 carries injection head 1 upward. Because stop 15 blocks base 16, as connecting rod 17 moves upward, it carries pressure plate 13 upward via stop 15 and base 16. This process is repeated to inject into multiple meat blocks.

[0049] During the injection of meat chunks by the injection needle 8, some of the injection fluid leaks onto the conveyor belt 10, and meat fragments from the meat chunks fall onto the conveyor belt 10 and mix with the injection fluid. As the conveyor belt 10 continues to rotate, when the conveyor belt 10 with the mixture adhering to it rotates downwards, the mixture will fall into the first recovery tank 3 below the conveyor belt 10 due to gravity. The mixture in the first recovery tank 3 flows into the second recovery tank 5. Since the edge of the outlet 18 of the second recovery tank 5 is in contact with the roller 4, the mixture in the second recovery tank 5 flows through the outlet 18 to the front end of the filter of the roller 4 and comes into contact with the surface of the roller 4. During filtration by the roller 4, the brine in the mixture is filtered by the filter holes 6. After passing through the filter holes 6, the brine drips downwards due to gravity and falls into the recovery port 7 of the storage tank 2 for reuse. The meat scraps in the mixture cannot pass through the filter holes 6 and adhere to the surface of the roller 4. As the roller 4 rotates, they are continuously scraped by the scraper 20, which scrapes off the meat scraps adhering to the surface of the roller 4. The scraped meat scraps will fall into the third recycling box 19 along the inclined surface of the scraper 20.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
