[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] like Figures 1 to 4 As shown, an embodiment of the present invention provides a meat grinder mechanism, including a stainless steel cylinder 1, a stainless steel three-way cylinder 2, a screw assembly 3, and a discharge plate 4. The stainless steel cylinder 1 is provided with a first through hole 11, and the stainless steel three-way cylinder 2 is provided with a second through hole 21 and a receiving cavity 22 communicating with the second through hole 21; the stainless steel cylinder 1 is installed on the stainless steel three-way cylinder 2, and the first through hole 11 communicates with the second through hole 21. The discharge plate 4 is provided with a shaft hole 41 and multiple discharge holes 42. The discharge plate 4 is installed in the receiving cavity 22. The stainless steel three-way cylinder 2 is provided with a connection port 26 communicating with the receiving cavity 22 at one end away from the discharge plate 4. One end of the screw assembly 3 is rotatably mounted in the shaft hole 41, and the other end of the screw assembly 3 passes through the connection port 26 and is located outside the receiving cavity 22.

[0021] The screw assembly 3 and the discharge plate 4 can both be made of stainless steel; the axis of the second through hole 21 is perpendicular to the axis of the receiving cavity 22; the stainless steel barrel 1 can be installed on the stainless steel three-way cylinder 2 by welding; the discharge plate 4 is provided with a plurality of discharge holes 42 arranged in an array, and the shaft hole 41 is located at the center of the discharge plate 4.

[0022] Specifically, ingredients can be sequentially fed into the receiving cavity 22 through the first through hole 11 and the second through hole 21; the end of the screw assembly 3 away from the discharge plate 4 is used to connect to the meat grinder drive mechanism, which can drive the screw assembly 3 to rotate in the receiving cavity 22, and the screw assembly 3 can convey and chop the ingredients toward the end of the discharge plate 4, and the chopped ingredients are output through the discharge hole 42.

[0023] In this embodiment, the design of the stainless steel barrel 1 and the stainless steel three-way barrel 2 allows them to be placed in a dishwasher for cleaning without oxidation. Furthermore, the design of the stainless steel barrel 1 reduces the length of the stainless steel three-way barrel 2 at the end facing the second through hole 21, thereby reducing the manufacturing difficulty of the stainless steel three-way barrel 2 and consequently lowering the manufacturing cost of the meat grinder mechanism. Especially when using casting to manufacture the stainless steel three-way barrel 2, the smaller length at the end facing the second through hole 21 significantly reduces the manufacturing difficulty of the mold for the stainless steel three-way barrel 2, further reducing the manufacturing cost of the meat grinder mechanism.

[0024] In one embodiment, such as Figure 3 and Figure 4 As shown, the meat grinder mechanism also includes a stainless steel chuck 5 mounted on the stainless steel three-way cylinder 2, and the stainless steel chuck 5 is provided with a locking part 51 for connecting the meat grinder drive mechanism.

[0025] The stainless steel chuck 5 can be installed on the stainless steel three-way cylinder 2 by welding; and the stainless steel chuck 5 is installed at the end of the stainless steel three-way cylinder 2 facing the connection port 26.

[0026] Since the stainless steel chuck 5 needs to be equipped with a locking part 51 for mounting the meat grinder drive mechanism, the structure of the stainless steel chuck 5 is relatively complex. If the stainless steel chuck 5 and the stainless steel three-way cylinder 2 were integrally formed, it would greatly increase the manufacturing difficulty of the stainless steel three-way cylinder 2. In this embodiment, the stainless steel chuck 5 and the stainless steel three-way cylinder 2 are designed separately, allowing them to be manufactured independently. This separate manufacturing of the stainless steel chuck 5 and the stainless steel three-way cylinder 2 further reduces the manufacturing cost of the meat grinder mechanism.

[0027] In one embodiment, such as Figure 2 As shown, a guide portion 23 is provided at the connection between the second through hole 21 and the receiving cavity 22. The guide portion 23 is used to guide the food in the second through hole 21 to the receiving cavity 22.

[0028] The guide portion 23 includes, but is not limited to, R-shaped chamfers, arc-shaped chamfers, etc., and the guide portion 23 is inclined toward one end of the receiving cavity 22.

[0029] In this embodiment, the guide part 23 can guide the food in the second through hole 21 to the receiving cavity 22, avoiding the accident of food getting stuck at the connection between the second through hole 21 and the receiving cavity 22, so that the food in the second through hole 21 can be smoothly input into the receiving cavity 22, ensuring the meat output rate of the meat grinder mechanism, and facilitating the cleaning of the meat grinder mechanism.

[0030] In one embodiment, such as Figure 2 As shown, the inner wall of the receiving cavity 22 is provided with a plurality of spiral ribs 27 distributed circumferentially at intervals; From one end of the connection port 26 toward one end of the shaft hole 41, the distance between two adjacent spiral ribs 27 gradually increases.

[0031] The spiral ribs 27 protrude toward the center of the receiving cavity 22, and the number of spiral ribs 27 can be set according to actual needs.

[0032] In this embodiment, as the screw assembly 3 rotates in the receiving cavity 22, the food in the receiving cavity 22 will move towards the discharge plate 4. The design of the spiral ribs 27 makes the movement of the food in the receiving cavity 22 towards the discharge plate 4 more stable. In addition, from one end of the connection port 26 towards one end of the shaft hole 41, the distance between two adjacent spiral ribs 27 gradually increases, making it less likely for blockage to occur as the food in the receiving cavity 22 moves towards the discharge plate 4.

[0033] In one embodiment, such as Figure 2 , Figure 5 and Figure 6 As shown, the screw assembly 3 includes a screw member 31 and a cutter wheel 32; the cutter wheel 32 is provided with a third through hole 321; the screw member 31 includes a screw body 311, a first connecting part 312 and a second connecting part 313, the first connecting part 312 and the second connecting part 313 are respectively disposed at opposite ends of the screw body 311; The cutting wheel 32 is sleeved on the first connecting part 312 through the third through hole 321. The first connecting part 312 is rotatably installed in the shaft hole 41. The second connecting part 313 passes through the connecting port 26 and is located outside the receiving cavity 22. The screw body 311 is located in the receiving cavity 22.

[0034] The screw body 311, the first connecting part 312, and the second connecting part 313 are integrally formed parts; the meat grinder driving mechanism is connected to the second connecting part 313, thereby driving the screw part 31 to rotate in the receiving cavity 22.

[0035] Specifically, the screw 31 can drive the cutting wheel 32 to rotate synchronously, the screw body 311 can convey the food towards one end of the cutting wheel 32, the cutting wheel 32 can chop the food, and the chopped food is then conveyed to the discharge plate 4 by the thrust of the screw body 311, and finally output to the external environment through the storage hole 42.

[0036] In this embodiment, the screw component 31 and the cutter wheel 32 are detachably connected, which improves the ease of cleaning the screw assembly 3; and the screw assembly 3 has a simple structure and low manufacturing cost.

[0037] In one embodiment, such as Figure 5 and Figure 6 As shown, the screw body 311 is also provided with a spiral blade 3111, and the spiral blade 3111 is provided with a protrusion 3112, which is used to squeeze the food in the receiving cavity 22.

[0038] In this embodiment, the design of the protrusion 3112 makes the surface of the spiral blade 3111 not smooth, so that the food is less likely to slip on the surface of the spiral blade 3111; and the protrusion 3112 can increase the squeezing force of the screw 31 on the food, so that the screw 31 can push the food to the discharge plate 4 more easily.

[0039] In one embodiment, such as Figure 5 and Figure 6 As shown, along the radial direction of the screw member 31, the cross-section of the third through hole 321 is a square hole; The first connecting part 312 includes a first round shaft section 3121 and a first square shaft section 3122, wherein the first square shaft section 3122 is connected between the first round shaft section 3121 and the screw body 311; The cutting wheel 32 is sleeved on the first square shaft section 3122, and the first round shaft section 3121 is rotatably installed in the shaft hole 41.

[0040] Wherein, the outer diameter of the first circular shaft segment 3121 is smaller than the width and length of the first square shaft segment 3122.

[0041] In this embodiment, the cutter wheel 32 is sleeved on the first square shaft section 3122, and the first round shaft section 3121 is rotatably inserted into the shaft hole 41. Thus, the screw member 31 can drive the cutter wheel 32 to rotate synchronously. It is not easy for slippage to occur between the screw member 31 and the cutter wheel 32, and the disassembly and assembly operations between the screw member 31 and the cutter wheel 32 are convenient.

[0042] In one embodiment, such as Figure 5 and Figure 6 As shown, the second connecting portion 313 is square along the radial direction of the screw member; The screw assembly 3 also includes a drive disk 33 with a square through hole 331, the drive disk 33 being sleeved on the second connecting part 313 through the square through hole 331; The drive disc 33 is provided with meshing teeth 332 located outside the receiving cavity 22. The meshing teeth 332 are used to connect to the output end of the meat grinder drive mechanism.

[0043] In this embodiment, the drive disk 33 is sleeved on the second connecting part 313 through the square through hole 331, so that the drive disk 33 can drive the screw 31 to rotate synchronously, and the disassembly and assembly operation between the drive disk 33 and the screw 31 is convenient; in addition, the output end of the meat grinder drive mechanism can be provided with an internal gear ring adapted to the meshing teeth 332, so that the meat grinder drive mechanism can drive the drive disk 33 to rotate through the meshing internal gear ring and the meshing teeth 332, the drive disk 33 drives the screw 31 to rotate, and the screw 31 drives the cutter wheel 32 to rotate.

[0044] In one embodiment, such as Figure 4 As shown, the stainless steel three-way cylinder 2 includes an integrally formed vertical cylinder 24 and a horizontal cylinder 25. The second through hole 21 is provided on the vertical cylinder 24, and the receiving cavity 22 and the connecting port 26 are both provided on the horizontal cylinder 25. The stainless steel material cylinder 1 is installed at the end of the vertical cylinder 24 away from the horizontal cylinder 25. The distance between the end of the vertical cylinder 24 away from the horizontal cylinder 25 and the horizontal cylinder 25 is 6mm to 14mm.

[0045] In this embodiment, the length of the vertical cylinder 24 is relatively short, so that the machining tool can be inserted into the receiving cavity 22 through the second through hole 21, thereby facilitating the machining of the guide portion 23 at the connection between the second through hole 21 and the receiving component; and the length of the vertical cylinder 24 should not be too short, because it is necessary to ensure the welding operation and welding strength between the vertical cylinder 24 and the stainless steel tray 1.
