[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 .

[0025] Example 1

[0026] A meat product brine injector includes a frame 1. The frame 1 is equipped with a conveying mechanism 2 for conveying meat blocks. A brine distributor 4 is installed at the upper end of the frame 1 via a telescopic mechanism 3. The brine distributor 4 is connected to an external brine tank via a main brine supply pipe 5. The brine distributor 4 is equipped with an injection needle 6. In use, the meat blocks are conveyed by the conveying mechanism 2. Driven by the telescopic mechanism 3, the brine distributor 4 moves downward, causing the injection needle 6 to pierce the meat blocks. Then, the brine in the external brine tank enters the brine distributor 4 through an external pump and the main brine supply pipe 5, and then enters the injection needle 6 through the brine distributor 4. The brine is then injected into the meat blocks through the injection needle 6 for marinating. The above is the prior art and will not be described in detail here.

[0027] The main innovation of this utility model is as follows:

[0028] Please see Figure 1 and Figure 5The injection needle 6 includes a fixed tube 61 and a movable needle tube 62. The upper end of the fixed tube 61 is fixedly connected to the saline dispenser 4 and is internally connected. The upper end of the movable needle tube 62 is movably disposed inside the lower end of the fixed tube 61. A groove 63 is provided on the upper side of the movable needle tube 62. A locking block 64 corresponding to the groove 63 is movably disposed on the inner wall of the fixed tube 61. Both the locking block 64 and the groove 63 are spherical structures. A spring 65 is connected between the locking block 64 and the inner wall of the fixed tube 61. Under the elastic force of the spring 65, the locking block 64 is locked in the groove 63, so that the movable needle tube 62 is limited to the lower end of the fixed tube 61.

[0029] With the above structure, when the injection needle 6 pierces the meat containing bone, the lower end of the movable needle tube 62 will be subject to resistance, so that the friction between the locking block 64 and the locking groove 63 is insufficient to continue to limit the movable needle tube 62. As a result, the locking block 64 disengages from the locking groove 63, and the movable needle tube 62 moves upward relative to the fixed tube 61, effectively preventing the movable needle tube 62 from continuing to move downward and breaking.

[0030] Furthermore, a baffle 7 is fixed below the brine distributor 4 on the frame 1. The baffle 7 has a through hole through which the lower end of the injection needle 6 passes. During injection, the telescopic mechanism 3 drives the injection needle 6 to pass through the through hole and pierce the meat block. After the brine is injected into the meat block, the telescopic mechanism 3 drives the injection needle 6 to move upward. Under the obstruction of the baffle 7, the injection needle 6 can be smoothly pulled out from the meat block.

[0031] Please see Figure 5 A sealing ring 66 is fixed to the upper side of the movable needle tube 62. The sealing ring 66 slides in contact with the inner wall of the fixed tube 61. The sealing ring 66 is set to ensure the sealing between the movable needle tube 62 and the fixed tube 61, so that the saline solution flows from the saline distributor 4 into the fixed tube 61 and then into the movable needle tube 62.

[0032] The injection needles 6 are arranged in a matrix at the bottom of the brine dispenser 4, so that the needles can be evenly inserted into the meat.

[0033] Please see Figure 4 The bottom of the saline dispenser 4 is provided with a threaded connector 10. The outer wall of the threaded connector 10 is threaded. The upper inner wall of the fixing tube 61 is threadedly connected to the outer wall of the threaded connector 10, so that the injection needle 6 can be easily disassembled and replaced.

[0034] Example 2

[0035] The structure of Example 2 is roughly the same as that of Example 1. The difference is that Example 2 adds a function for detecting needle malfunctions on the basis of Example 1.

[0036] It is understandable that when the injection needle 6 pierces the meat, it may retract or break. Retraction means that the movable needle tube 62 retracts into the fixed tube 61, which will prevent the needle from piercing the meat in the next injection. Breakage may cause the needle to remain in the meat, creating a safety hazard and affecting subsequent saline injections. In order to facilitate staff to be aware of the above two situations in a timely manner and take corresponding measures, the baffle 7 is equipped with a needle failure detection mechanism 8 at the through hole.

[0037] The needle fault detection mechanism 8 includes a push button switch 81. The push button switch 81 is existing technology, which refers to a switch that uses a button to push a transmission mechanism to make the moving contact and the stationary contact open or close and realize the circuit switching. The number of push button switches 81 is equal to that of the injection needles 6 and their positions correspond to each other. The push button switch 81 is fixedly connected to a mounting plate 82. A drive mechanism 83 is connected between the mounting plate 82 and the baffle 7. The drive mechanism 83 is used to drive the mounting plate 82 to move, so that the push button switch 81 is close to the through hole and contacts the side of the movable needle tube 62.

[0038] With the above structure, after the injection is completed, the telescopic mechanism 3 will move the lower end of the injection needle 6 to the top of the baffle 7. Under the obstruction of the baffle 7, the lower end of the injection needle 6 will be pulled away from the meat block. Then, the drive mechanism 83 will drive the mounting plate 82 to move, causing the button switch 81 to move towards the through hole position. If the needle is intact, the button switch 81 will be squeezed when it moves to the needle position, thereby connecting the corresponding circuit. Conversely, if the needle retracts or breaks, the button switch 81 will not be able to touch the needle when it moves to the through hole position, thus preventing the corresponding circuit from being connected. In this way, the detection of needle failure is achieved.

[0039] In this embodiment, the drive mechanism 83 is an electric telescopic rod.

[0040] To facilitate the display of fault conditions, a display 9 is fixed to the frame 1. The push-button switch 81 is electrically connected to the display 9. The display 9 can be equipped with an equal number of indicator lights as the push-button switch 81. Each indicator light corresponds to a circuit connected to the push-button switch 81. During testing, the drive mechanism 83 drives the mounting plate 82 to move, bringing the push-button switch 81 closer to the needle. If the indicator light corresponding to the push-button switch 81 does not light up, it indicates that the needle corresponding to the push-button switch 81 is abnormal. Through the above structure, it is convenient for staff to know the fault condition of the needle in a timely manner, and to find the faulty needle in a timely manner when a needle malfunctions.

[0041] In summary, this utility model aims to provide an improved brine injection machine for meat products. By designing an injection needle 6 with a movable needle tube 62 and a fixed tube 61, it effectively avoids the problem of needle breakage caused by excessive impact force or excessive bone hardness when piercing meat containing bones. At the same time, a needle failure detection mechanism 8 is added, which can detect needle retraction or breakage in a timely manner, reducing the health risks to consumers.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
