Description

Technical Field

[0001] This utility model relates to the field of blade anti-jamming technology, and in particular to an anti-jamming blade assembly structure for a meat grinder. Background Technology

[0002] Traditional meat grinders face numerous problems during the meat grinding process. On one hand, tendons and frozen meat chunks easily become entangled in the blade shaft during grinding, causing a sudden and significant increase in power load, and in severe cases, even machine shutdown, affecting production continuity and efficiency. On the other hand, traditional cross-blades or spiral blades have low cutting efficiency when processing highly viscous minced meat, and meat particles easily accumulate between the blades, further reducing grinding efficiency and increasing production and time costs. Therefore, we propose an anti-jamming blade assembly structure for meat grinders to address these issues. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-jamming blade assembly structure for a meat grinder.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A meat grinder anti-jamming blade assembly structure includes a rotating shaft, one end of which is connected to a rotating mechanism. Multiple grinding blades are fixed at equal intervals around the circumference of the rotating shaft. Multiple rectangular guide grooves are evenly spaced on one side of the bottom of each grinding blade. A conveying shaft is installed inside the rotating shaft. One end of the conveying shaft is connected to a rotating mechanism, and one end of the rotating mechanism is connected to a high-pressure air supply mechanism. Multiple second spray holes are evenly spaced on the sidewall of the conveying shaft. Multiple first spray holes, corresponding to the second spray holes, are evenly spaced on the sidewall of the rotating shaft, and the first spray holes are located on one side of the bottom of the grinding blade.

[0006] Preferably, the rotating mechanism includes a mounting base installed on one side of the rotating shaft, a drive motor is provided on one side of the mounting base, gears are fixed at the ends of both the rotating shaft and the output shaft of the drive motor, and a chain meshes between the two gears.

[0007] Preferably, the rotating shaft is provided with a slot, one side of the slot is provided with a groove, and a locking block is fixed to one side of the upper end of the conveying shaft, the locking block being engaged in the groove.

[0008] Preferably, the rotating structure includes a protective box disposed on one side of the conveying shaft, an mounting plate is installed on the upper side of the protective box, a rotary joint is rotatably sleeved on the mounting plate, and the rotating end of the rotary joint is fixedly connected to one end of the conveying shaft.

[0009] Preferably, the high-pressure gas transmission mechanism includes a high-pressure gas pump installed at the bottom of the protective box, the gas transmission end of the high-pressure gas pump is connected to a gas transmission pipe, and one end of the gas transmission pipe is connected to the fixed end of the rotary joint.

[0010] Preferably, the bottom side of the crushing blade is provided with multiple arc-shaped guide grooves at equal intervals.

[0011] In this invention, multiple shredding blades are fixed at equal intervals on a rotating shaft for cutting meat. A conveyor shaft passes through the rotating shaft and has multiple second nozzles connected to the first nozzles. These nozzles correspond to the roots of the shredding blades. When the machine is running, high-pressure gas is supplied to the conveyor shaft. The high-pressure gas is ejected from the nozzles and impacts the roots of the shredding blades. The fascia and meat pieces wrapped around the roots of the blades are then dislodged under the action of the high-pressure gas, thus preventing jamming.

[0012] In this invention, a radial guide groove is provided at the root of the crushing blade. During the rotation of the blade, a centrifugal force is generated. The debris generated during the crushing process is guided to the outer collection chamber along the radial guide groove under the action of centrifugal force. This not only reduces the accumulation of debris around the blade and ensures the normal cutting of the blade, but also facilitates the subsequent cleaning and treatment of debris.

[0013] This utility model has the following advantages:

[0014] 1. By solving the problems of fascia and frozen meat chunks entangled in the blade shaft and meat particles accumulating in the gap between the blades, the machine downtime due to material jamming is reduced, allowing the meat grinding process to proceed continuously and stably, greatly improving grinding efficiency and thus enhancing overall production efficiency.

[0015] 2. It reduces material jamming, lowers power load, avoids damage to the machine caused by sudden load increases, extends the service life of the blades and the machine, and reduces the frequency of equipment maintenance and replacement costs.

[0016] 3. The efficient cutting and grinding process makes the minced meat more uniform and delicate, improving the quality of the minced meat and facilitating the subsequent processing of meat products and the production of higher quality products.

[0017] 4. By combining high-pressure gas impact with centrifugal chip guidance, it can adapt to different types of meat grinding, improving the overall grinding performance;

[0018] In summary, this invention solves the problems of fascia and frozen meat chunks entangled in the blade shaft and meat particles accumulating in the blade gap, reducing machine downtime due to material jamming, enabling the meat grinding process to proceed continuously and stably, greatly improving grinding efficiency, and thus enhancing overall production efficiency. In addition, it reduces material jamming, lowers the power load, avoids damage to the machine caused by sudden load increases, and extends the service life of the blades and the machine.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 A meat grinder anti-jamming blade assembly structure includes a rotating shaft 7, one end of which is connected to a rotating mechanism. Multiple grinding blades 5 are fixed at equal intervals around the circumference of the rotating shaft 7. The grinding blades 5 are made of high-strength alloy material and can easily cut various meats. The blades have a certain curvature, which can grind the meat more smoothly during the cutting process and reduce cutting resistance.

[0027] Multiple rectangular guide grooves 19 are provided at equal intervals on one side of the bottom of the crushing blade 5, and multiple arc-shaped guide grooves 14 are provided at equal intervals on one side of the bottom of the crushing blade 5. As the blade rotation generates centrifugal force, the debris generated during the crushing process will be guided to the outer collection chamber along these radial guide grooves under the action of centrifugal force. The collection chamber is located around the periphery of the shredder.

[0028] A conveyor shaft 8 is installed inside the rotating shaft 7. One end of the conveyor shaft 8 is connected to a rotating structure, and the other end of the rotating structure is connected to a high-pressure gas conveying mechanism. Multiple second nozzles 10 are evenly spaced on the side wall of the conveyor shaft 8, and multiple first nozzles 6 corresponding to the second nozzles 10 are evenly spaced on the side wall of the rotating shaft 7. The first nozzles 6 are located on the bottom side of the crushing blade 5. The high-pressure air pump 18 can generate stable and powerful air pressure to ensure that the gas delivered to the conveyor shaft 8 has sufficient impact force. The gas is delivered to the rotary joint 13 through the air conveying pipe 17 and then enters the conveyor shaft 8. The high-pressure gas is ejected from the second nozzles 10 and the first nozzles 6 to impact the root of the crushing blade 5. During the meat grinding process, tendons and meat pieces are easy to get tangled at the root of the blade. The impact of the high-pressure gas can make these tangled materials be blown away under the action of the high-pressure gas, thereby effectively preventing the occurrence of material jamming.

[0029] The rotating mechanism includes a mounting base 4 installed on one side of the rotating shaft 7. A drive motor 1 is provided on one side of the mounting base 4. Gears 2 are fixed at the ends of the rotating shaft 7 and the output shaft of the drive motor 1, and a chain 3 meshes between the two gears 2. After the drive motor 1 is started, its output shaft drives the gear 2 connected to it to rotate. Through the transmission of the chain 3, the gear 2 on the rotating shaft 7 also rotates, thereby driving the rotating shaft 7 to rotate.

[0030] The rotating shaft 7 is provided with a slot 11, and a slot 15 is provided on one side of the slot 11. A locking block 12 is fixed on one side of the upper end of the conveying shaft 8. The locking block 12 is engaged in the slot 15. The engaging structure allows the conveying shaft 8 to be securely installed in the rotating shaft 7. At the same time, it can be easily disassembled and installed when maintenance or replacement of the conveying shaft 8 is required.

[0031] The rotating structure includes a protective box 9 located on one side of the conveying shaft 8. An mounting plate 16 is installed on the upper side of the protective box 9. A rotary joint 13 is rotatably sleeved on the mounting plate 16. The rotating end of the rotary joint 13 is fixedly connected to one end of the conveying shaft 8. The function of the rotary joint 13 is to ensure the stable delivery of high-pressure gas even when the conveying shaft 8 is rotating.

[0032] The high-pressure air supply mechanism includes a high-pressure air pump 18 installed at the bottom of the protective box 9. The air supply end of the high-pressure air pump 18 is connected to an air supply pipe 17. One end of the air supply pipe 17 is connected to the fixed end of the rotary joint 13. The high-pressure air pump 18 has the function of adjustable air pressure. The staff can flexibly adjust the air pressure according to different types of meat and mincing requirements to achieve the best anti-jamming effect.

[0033] In this invention, multiple shredding blades 5 are fixed at equal intervals on the rotating shaft 7 for cutting meat. A conveying shaft 8 passes through the rotating shaft 7 and is provided with multiple second spray holes 10 that are connected to the first spray holes 6. These spray holes correspond exactly to the root of the shredding blades 5. When the machine is running, high-pressure gas is supplied to the conveying shaft 8. The high-pressure gas is ejected from the spray holes and impacts the root of the shredding blades 5. The fascia and meat pieces wrapped around the root of the blades are then flushed away under the action of the high-pressure gas, thereby preventing the occurrence of material jamming.

[0034] The five shredder blades have radial guide grooves. During the rotation of the blades, centrifugal force is generated. The debris generated during the shredding process is guided to the outer collection chamber along the radial guide grooves under the action of centrifugal force. This not only reduces the accumulation of debris around the blades and ensures normal cutting, but also facilitates the subsequent cleaning and treatment of debris.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
