Description

Technical Field

[0001] The present application relates to the field of meat mincing devices, and in particular to a meat mincing device for pet staple food. Background Art

[0002] Currently, there are a wide variety of meat mincing devices available on the market for the production of puffed pet food. These devices are primarily used to cut large chunks of meat into small pieces or mince for subsequent processing and mixing. However, traditional meat mincing devices typically only have basic cutting functions and are not specifically designed to add and evenly mix additional ingredients such as fish oil. This limitation often makes it difficult for traditional meat mincing devices to achieve uniform distribution of fish oil when processing raw materials that require mixing, affecting the nutritional balance of pet food.

[0003] To address the problem of traditional meat mincing devices being unable to effectively mix fish oil, some existing technical solutions have added oil-adding mechanisms to the mincing devices, achieving mixing by spraying the oil directly into the minced meat. However, these solutions still have many shortcomings. For example, some devices cannot maintain a uniform flow when spraying fish oil, as fish oil easily solidifies at low temperatures, resulting in uneven spraying. Furthermore, some devices lack an effective mixing mechanism when spraying oil, making it impossible to ensure that the fish oil and minced meat are fully integrated. These problems result in uneven distribution of fish oil in the produced pet food, leading to an unbalanced nutritional composition and adverse effects on pet health.

[0004] Although existing technical solutions attempt to add fish oil during the mincing process, due to the lack of a special oil-distributing structure and a design to prevent the fish oil from solidifying, they still cannot effectively solve the problems of uniform mixing of the fish oil and preventing the fish oil from solidifying. Specifically, the existing solutions are prone to problems such as grease clogging the nozzle, uneven fish oil spraying, and incomplete oil mixing during the fish oil addition process. In addition, the traditional fixing and transmission structure cannot ensure that the equipment remains stable and efficient during long-term operation. These defects seriously affect the production efficiency and product quality of pet puffed staple food. Therefore, there is an urgent need for an improved meat mincing device that can effectively mix fish oil and prevent fish oil from solidifying to improve the nutritional value and production efficiency of pet food.

[0029] An embodiment of the present application provides a meat mincing device for pet staple food, comprising a meat mincer, the meat mincer including an oil inlet structure, and the meat mincing device further comprising:

[0030] An oil conveyor is provided on one side of the oil inlet structure, the oil conveyor includes a drive mechanism, an oil inlet pipe and an oil outlet pipe, the oil inlet pipe and the oil outlet pipe are connected through the drive mechanism, the oil inlet pipe is connected to the oil inlet structure, an end of the oil outlet pipe away from the drive mechanism is provided above the oil inlet structure, the drive mechanism drives the oil in the oil outlet pipe to flow to the oil inlet structure, and the drive mechanism drives the oil in the oil inlet structure to flow into the oil inlet pipe;

[0033] The following is combined with Figure 1-5 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] An embodiment of the present application provides a meat mincing device 100 for pet staple food, comprising a meat mincer 1, wherein the meat mincer 1 includes an oil inlet structure 2, and further comprising:

[0035] An oil conveyor 3 is provided on one side of the oil balancing structure 7. The oil conveyor 3 includes a driving mechanism 4, an oil inlet pipe 5, and an oil outlet pipe 6. The oil inlet pipe 5 and the oil outlet pipe 6 are connected through the driving mechanism 4. The oil inlet pipe 5 is connected to the oil balancing structure 7. One end of the oil outlet pipe 6 away from the driving mechanism 4 is provided above the oil inlet structure 2. The driving mechanism 4 drives the oil in the oil outlet pipe 6 to flow to the oil inlet structure 2. The driving mechanism 4 drives the oil in the oil balancing structure 7 to flow into the oil inlet pipe 5.

[0036] The oil balancing structure 7 is located below the meat mincer 1. The oil balancing structure 7 includes a rotating shaft 8, an oil balancing plate 9 and a vibration device. The oil balancing plate 9 can store oil. The vibration device 10 and the rotating shaft 8 are both provided on the oil balancing plate 9. The vibration device 10 can drive the oil balancing plate 9 to vibrate and simultaneously rotate the oil balancing plate 9 along the axial direction of the rotating shaft 8 to make the oil on the oil balancing plate 9 flow.

[0037] Specifically, the pet staple food mincing device involved in the present invention includes a meat mincer 1 and an oil inlet structure 2, the oil inlet structure 2 is connected to the oil conveyor 3, the oil conveyor 3 includes a driving mechanism 4, an oil inlet pipe 5 and an oil outlet pipe 6, wherein the oil inlet pipe 5 is connected to the oil equalizing structure 7, and the end of the oil outlet pipe 6 away from the driving mechanism 4 is arranged above the oil inlet structure 2. The function of the driving mechanism 4 is to convey the oil flow from the oil outlet pipe 6 to the oil inlet structure 2, and at the same time, the oil in the oil equalizing structure 7 flows to the oil inlet pipe 5, thereby realizing uniform oil delivery. The oil equalizing structure 7 includes a rotating shaft 8, an oil equalizing plate 9 and a vibration device. The oil equalizing plate 9 is used to store oil. The vibration device drives the vibration of the oil equalizing plate 9 and makes it rotate along the rotating shaft 8 to promote the uniform flow of oil. This structure can effectively avoid uneven distribution of oil during use, thereby improving the operating efficiency and stability of the meat mincer 1. The oil inlet pipe 5 is connected with the oil equalizing structure 7, ensuring the flow path and direction of the oil before entering the oil equalizing structure 7. The oil outlet pipe 6 is controlled by the driving mechanism 4 so that the oil can be accurately transported to the oil inlet structure 2, thereby realizing the oil equalizing function. The combination of the vibration device 10 and the rotating shaft 8 on the oil equalizing plate 9 can ensure the uniform distribution of oil, reduce local accumulation of oil, and improve the stability and use effect of the equipment. The driving mechanism 4 transports the oil to the oil equalizing structure 7 through the oil inlet pipe 5. The oil equalizing plate 9 vibrates and rotates along the rotating shaft 8 under the drive of the vibration device 10. The oil flows evenly on the oil equalizing plate 9 and then flows to the oil inlet structure 2 through the oil outlet pipe 6. This device is particularly suitable for use in meat grinders 1 where precise control of oil distribution is required, for example, in the production of pet food, to ensure uniform mixing of oil and raw materials, thereby improving the quality of the final product.

[0038] In a specific example, the oil balancing structure 7 includes an oil balancing plate 9 and an oil outlet plate 11, the oil balancing plate 9 is arranged above the oil outlet plate 11, and the oil balancing plate 9 and the oil outlet plate 11 are arranged side by side, the meat mincing device for the pet staple food includes a first fixed group 12, one end of the rotating shaft 8 is rotatably connected to the oil balancing plate 9, and the other end is rotatably connected to the first fixed group 12.

[0039] Specifically, the oil-balancing structure 7 includes an oil-balancing plate 9 and an oil-discharging plate 11. The oil-balancing plate 9 is disposed above the oil-discharging plate 11, and the two are disposed side by side. The meat-crushing device for pet staple food also includes a first fixed group 12. One end of the rotating shaft 8 is rotatably connected to the oil-balancing plate 9, and the other end is rotatably connected to the first fixed group 12. This structure enables the oil-balancing plate 9 and the oil-discharging plate 11 to maintain a stable relative position. The setting of the rotating shaft 8 allows the oil-balancing plate 9 to maintain balance during rotation, thereby improving the uniform distribution efficiency of the oil. The rotating shaft 8 drives the oil-balancing plate 9 to rotate, and the oil is evenly distributed on the oil-balancing plate 9 and flows out through the oil-discharging plate 11, ensuring that the oil inside the meat chopper 1 is evenly distributed.

[0040] In a specific example, the meat mincing device for the pet staple food includes a second fixed group 13 , and the meat mincer 1 includes a fixed plate 14 and a crushing device 15 . The crushing device 15 is provided on the fixed plate 14 , and the fixed plate 14 is rotatably connected to the second fixed group 13 .

[0041] Specifically, the meat mincing device includes a second fixed group 13, and the meat mincer 1 includes a fixed plate 14 and a crushing device 15. The crushing device 15 is arranged on the fixed plate 14, and the fixed plate 14 is rotatably connected to the second fixed group 13. This structure allows the crushing device 15 to work stably on the fixed plate 14, and the rotatable connection between the fixed plate 14 and the second fixed group 13 enables the crushing device 15 to adapt to different operating angles, thereby improving the applicability and stability of the meat mincer 1. The rotatable connection of the fixed plate 14 enables the crushing device 15 to adjust the angle to adapt to different mincing requirements, thereby improving working flexibility.

[0042] In a specific example, the oil balancing structure 7 includes a damping hydraulic rod 16 , one end of which is disposed on the oil balancing plate 9 , and the other end of which is disposed on the oil outlet plate 11 .

[0043] Specifically, the oil balancing structure 7 includes a shock-absorbing hydraulic rod 16, one end of which is arranged on the oil balancing plate 9, and the other end is arranged on the oil outlet plate 11. The setting of the shock-absorbing hydraulic rod 16 can effectively reduce shock, reduce the vibration between the oil balancing plate 9 and the oil outlet plate 11, ensure the uniformity of oil distribution, and improve the stability and service life of the equipment. The shock-absorbing hydraulic rod 16 absorbs vibration and prevents the oil balancing plate 9 and the oil outlet plate 11 from excessive vibration during operation, thereby maintaining uniform distribution of oil.

[0044] In a specific example, the oil inlet structure 2 includes an oil inlet screen plate 17 , an oil inlet hole is opened on the crushing device 15 , and the oil inlet screen plate 17 is arranged in the oil inlet hole;

[0045] The oil inlet screen plate 17 also includes a fixed oil inlet screen plate 19 and a movable oil inlet screen plate 20. The fixed oil inlet screen plate 19 is fixedly connected to the oil inlet hole. One end of the movable oil inlet screen plate 20 is slidably connected to the fixed oil inlet screen plate 19, and the other end abuts against an end away from the fixed oil inlet screen plate 19.

[0046] Specifically, the main function of this design is to control the inflow speed of oil and prevent oil leakage or blockage in the oil inlet hole. By dividing the oil inlet screen plate 17 into fixed and movable parts, the oil flow rate can be accurately controlled, thereby effectively avoiding leakage caused by too fast oil flow or blockage caused by too slow oil flow. This design improves the working efficiency of the meat chopper 1 and ensures the normal operation and long-term stability of the equipment. During operation, the movable oil inlet screen plate 20 adjusts the oil inlet amount through the sliding function to keep the oil inlet hole clean and the oil flow smooth. According to actual needs, the movable screen plate can slide on the fixed screen plate and change its position to adjust the oil inflow speed to ensure that the oil amount in the crushing device 15 is properly controlled, thereby improving the overall efficiency and performance of the meat chopper 1.

[0047] In a specific example, the meat mincing device includes a third fixed group 21, and the third fixed group 21 includes a telescopic hydraulic rod 22. One end of the telescopic hydraulic rod 22 is provided on the third fixed group 21, and the other end is fixedly connected to the fixed plate 14. The telescopic hydraulic rod 22 can drive the fixed plate 14 to rotate around the axis of the roller 24.

[0048] Specifically, this design allows the user to adjust the angle of the fixed plate 14 according to actual needs, making the mincing operation more flexible and adaptable. By adjusting the angle of the fixed plate 14, the material contact angle and effect during the mincing process can be optimized, improving mincing efficiency and adapting to different material types or processing requirements. The telescopic hydraulic rod 22 controls the rotation angle of the fixed plate 14, enabling adaptability of the mincing device under different operating conditions. During operation, the telescopic hydraulic rod 22 drives the fixed plate 14 to rotate about the roller 24, allowing the position and angle of the fixed plate 14 to be precisely controlled, thereby achieving rapid adaptation to different mincing requirements.

[0049] In a specific example, a groove and a groove bolt are provided on the first fixing group 12 , and the oil pump 3 is disposed in the groove and connected with the groove bolt.

[0050] Specifically, the groove design provides stable support for the oil pump 3, and the bolt connection firmly secures the oil pump 3 to the first fixing group 12. This structure improves the stability and reliability of the device, reduces vibration and displacement that may occur during operation, and thus ensures its long-term stable operation. The oil pump 3 is fixed to the first fixing group 12 via the groove and bolts. The groove design allows for precise positioning and fixation of the oil pump 3, while the bolt connection provides additional mechanical fixing force, ensuring the stability of the device during operation. This effectively reduces vibration and displacement of the equipment, improving operational accuracy and safety.

[0051] In a specific example, the second fixing group 13 includes a roller 24 , one end of the roller 24 is welded to the second fixing group 13 , and the other end is rotatably connected to the fixing plate 14 .

[0052] Specifically, the setting of the roller 24 allows the fixed plate 14 to rotate freely, thereby improving the operational flexibility of the meat mincing device. The rotation ability of the fixed plate 14 allows the operator to adjust the operating angle according to actual needs, thereby adapting to different meat mincing tasks or processing conditions. The setting of the roller 24 allows the fixed plate 14 to rotate around its axis. During operation, the roller 24 supports the rotation of the fixed plate 14 through its rotation axis, so that the operator can easily adjust the angle of the fixed plate 14 to optimize the operating effect and adapt to different work requirements. The design of the roller 24 ensures the smoothness and stability of the rotation process.

[0053] In a specific example, the oil-distributing structure 7 is made of stainless steel.

[0054] Specifically, the use of stainless steel improves the durability and corrosion resistance of the oil-balancing structure 7. Stainless steel's excellent corrosion and wear resistance significantly extends the life of the equipment, reducing maintenance frequency and replacement costs. This makes the equipment more reliable and economical over long-term use. The use of stainless steel ensures the stability and durability of the oil-balancing structure 7 over long periods of use. The corrosion and wear resistance of the material reduces maintenance frequency and improves the stability of the equipment under various operating conditions, thereby extending the overall service life of the equipment.

[0055] In a specific example, the meat mincing device includes a push rod 26, a meat inlet 27 and a meat outlet 28. The push rod 26 is arranged on the movable oil inlet screen plate 20. The movable oil inlet screen plate 20 and the fixed oil inlet screen plate 19 slide relative to each other to expose the through hole to form the meat outlet 28. The meat inlet 27 is arranged at the end of the crushing device 15 away from the meat outlet 28.

[0056] Specifically, this design can effectively control the flow of the meat inlet 27 and the meat outlet 28, ensuring the continuity and stability of the meat mincing process. By adjusting the opening size of the meat outlet 28, the flow rate of the material can be accurately controlled, thereby improving the efficiency and stability of the meat mincing process. The push rod 26 slides the oil inlet screen plate 20 so that the meat outlet 28 can adjust the opening size according to actual needs. The adjusted meat outlet 28 can effectively control the flow of materials and ensure the continuity and stability of the meat mincing process. The sliding function of the push rod 26 enables the user to adjust according to specific operating requirements to optimize the effect of the meat mincing process.

[0057] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
