Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically relating to a meat cutting module and a meat cutting machine. Background Technology

[0002] For all kinds of kitchen operations, food preparation before cooking is always an essential step. For Chinese cooking, which has many cooking methods and a wide variety of ingredients, food preparation is even more diverse. Cutting meat into chunks or strips is a common food preparation step. For electric meat cutting modules, a comb is usually used as a guide to guide the ingredients into the cutting area, and then the ingredients are cut by two sets of blades.

[0003] However, the mounting structure of the comb and blades is often fixed inside the meat cutting module. As a result, these combs and blades can only be used in this fixed-size meat cutting module. When you want to change the spacing between the comb and blades according to the requirements of food preparation, you need to replace the entire meat cutting structure, which is time-consuming, laborious and has high material costs. Summary of the Invention

[0004] To address the aforementioned technical problems, this application further improves the meat-cutting structure within the meat-cutting module, aiming to resolve these issues and obtain a meat-cutting module with adjustable blade spacing. One objective of this invention is to provide a meat-cutting module, and another is to provide a corresponding meat-cutting machine.

[0005] The specific technical solution is explained below:

[0006] The meat cutting module includes:

[0007] A meat-cutting container that provides the space needed for meat-cutting operations;

[0008] A meat ingredient inlet is connected to the upper part of the meat cutting container, and the meat ingredient inlet includes a channel for introducing meat ingredients into the meat cutting container.

[0009] The meat-cutting structure is provided inside the meat-cutting container. The meat-cutting structure includes a comb section and a cutting board section. The comb section includes at least two sets of comb tooth assemblies. Each set of comb tooth assemblies includes a comb tooth shaft and several comb teeth slidably connected to the comb tooth shaft. The comb tooth shaft is mounted on the upper edge of the power input end plate, the cutter baffle, and the outer end plate. The cutting board section includes at least two sets of cutting board assemblies. Each cutting board assembly includes a cutting board shaft and several blades slidably connected to the cutting board shaft. Each comb tooth is disposed between two adjacent blades. One end of the cutting board shaft is axially rotatably linked to the power input end plate, and the other end is hinged to the outer end plate.

[0010] The gearbox includes a gear drive shaft, a gear set, and an output section. The gear drive shaft is used to transmit input power. The gear set includes a first meat-cutting drive gear and a second meat-cutting drive gear. The first meat-cutting drive gear is driven by the gear drive shaft, and the second meat-cutting drive gear is driven by the first meat-cutting drive gear in a direction-to-direction rotational connection. The output section is disposed on the power input end plate and includes two sub-output sections. The two sub-output sections are driven by the first meat-cutting drive gear and the second meat-cutting drive gear, respectively, in a synchronous rotational connection.

[0011] In the above technical solution, the comb teeth can slide on the comb tooth shaft, which facilitates the adjustment of the spacing between each comb tooth and the total width of several comb teeth. The total spacing of several blades on the knife and chopping board assembly can be adjusted. Since each comb tooth is set between two blades, each time the spacing between the blades is adjusted, the position of each comb tooth needs to be adjusted synchronously to continue to maintain a comb tooth between every two adjacent blades to guide the food downward. In the technical solution of the present invention, the comb teeth are slidably hooked on the comb tooth shaft, which is convenient for adjustment.

[0012] The output section of the gearbox, driven by the gear transmission structure, causes the cutting board to rotate and cut the food.

[0013] Preferably, the tool baffle is slidably connected to the tool holder shaft, and the tool baffle and the power input end plate form a plurality of working areas for the blades;

[0014] It also includes a baffle adjustment component, comprising an adjustment screw and an adjustment knob that drives the adjustment screw to rotate. The adjustment screw is screwed into an adjustment screw hole opened on the outer end plate. One end of the adjustment screw located on the inner side of the outer end plate abuts against the tool baffle, and the other end located on the outer side of the outer end plate is connected to the adjustment knob.

[0015] In the above technical solution, the blade spacing is positioned by the baffle adjustment component after adjustment, thereby adapting to different cutting needs of the cutting board, and the adjustment structure is simple and the adjustment operation is convenient.

[0016] Preferred options also include:

[0017] The snap-fit ​​portion includes at least two sets of snap-fit ​​assemblies that match the number of the comb teeth assembly. Each set of snap-fit ​​assemblies includes a first end-sealing snap at one end, a second end-sealing snap at the other end, and a cutter baffle snap located between the first end-sealing snap and the second end-sealing snap. A plurality of the comb teeth are disposed between the second end-sealing snap and the cutter baffle snap.

[0018] The first end-sealing bayonet is disposed on the upper edge of the outer end plate, the second end-sealing bayonet is disposed on the upper edge of the power input end plate, and the tool baffle bayonet is disposed on the upper edge of the tool baffle;

[0019] The first end-sealing bayonet, the second end-sealing bayonet, and the cutter baffle bayonet all have upward-facing openings for the comb shaft to enter and exit, and the comb shaft is mounted on several bayonet slots of the same set of bayonet assemblies.

[0020] In the above technical solution, the comb shaft is mounted on several bayonet slots with openings, which facilitates disassembly and assembly.

[0021] Preferably, the openings of the first and second sealing ends are provided with limiting covers that at least partially cover the openings. The limiting covers at both ends are used to form a limiting structure at both ends of the comb shaft above, preventing the comb shaft from moving upward.

[0022] Preferably, the limiting cover on the opening of the first sealing end bayonet partially covers the opening, and the covering position is located on the side of the opening away from the second sealing end bayonet; the limiting cover on the opening of the second sealing end bayonet partially covers the opening, and the covering position is located on the side of the opening away from the first sealing end bayonet. In this technical solution, the limiting cover is set as far as possible towards both ends to leave relatively ample space and not to obstruct the assembly of the comb shaft.

[0023] Preferably, the cutter baffle slot is disposed on the upper edge of the cutter baffle, and the cutter baffle has an adjustment range that moves along the axial direction of the comb shaft.

[0024] Preferably, the bottom of the bayonet has a limiting surface that at least partially conforms to the outer contour of the comb shaft to prevent the comb shaft from wobbling within the bayonet.

[0025] Preferably, the comb teeth include a connecting part and a guiding part. The connecting part is movably connected to the comb tooth shaft, and the guiding part has a guiding surface with a downwardly increasing inclination to guide the food to move downward into the cutting area.

[0026] More preferably, the connecting part is provided with a through hole, and the comb shaft passes through the through hole and is slidably connected to the connecting part.

[0027] More preferably, the through hole has an inner contour that fits and conforms to the surface of the comb shaft, which can prevent the comb shaft from shaking in the through hole.

[0028] Preferably, several of the comb teeth have a consistent shape and size, thereby unifying the guiding function of the comb and enhancing the stability of the guidance.

[0029] Preferably, a variable-pitch elastic sheet is provided between two adjacent blades;

[0030] The variable-pitch elastic sheet is provided with a variable-pitch connecting through hole that is slidably connected to the knife-handle shaft, and is also provided with a variable-pitch portion having an elastically expandable and contractile gap in the axial direction of the knife-handle shaft; preferably, the variable-pitch portion includes two partially spaced-apart partial elastic sheets, the two partial elastic sheets having ends connected together and spaced-apart variable-pitch intervals; more preferably, the partial elastic sheets have force-bearing surfaces that abut against adjacent blades, and the two force-bearing surfaces on the same variable-pitch portion are spaced apart to form the variable-pitch intervals.

[0031] In the above technical solution, the variable pitch elastic plate not only allows the total distance between multiple blades to be adjusted by the degree of compression of the tool baffle, but also allows the distance between adjacent blades to be adjusted accordingly. When the degree of compression of the tool baffle is large, the variable pitch part is compressed, and the total distance between several blades and the distance between adjacent blades both become smaller. When the degree of compression of the tool baffle is small, the variable pitch part recovers its deformation under the action of its own elastic force, and the total distance between several blades and the distance between adjacent blades both increase.

[0032] Meanwhile, each force-bearing surface is connected to the adjacent end via a spring-loaded ramp. When the force-bearing surface is subjected to pressure, the spring-loaded ramp deforms and gives the force-bearing surface a spring-loaded force in the opposite direction to the pressure. This spring-loaded force causes the force-bearing surface to press tightly against the blade, preventing the blades from becoming loose and deformed, which would be detrimental to cutting.

[0033] Preferably, the variable pitch elastic sheet is formed by connecting two elastic rings, with at least two connection points between the two elastic rings. The variable pitch portion is formed between two adjacent connection points. This structure is relatively simple and easy to manufacture into variable pitch elastic sheet products.

[0034] Preferably, the number of the knife and chopping board components is two sets.

[0035] Preferably, the contact point between the adjusting screw and the tool baffle is located between the two tool holder shafts, so that the compressive force is applied evenly to the tool baffle.

[0036] Preferably, the two sets of blades between two adjacent sets of cutting tool assemblies are staggered along the axial direction of the cutting tool shaft, and several of the blades are circular blades of the same shape and size to form a reasonable cutting area, enhance the stability of cutting, and save the cost of manufacturing blades.

[0037] Preferably, the gear drive shaft and the outer casing of the gearbox are rotatably sealed together by a first sealing ring;

[0038] The two sub-output sections are rotatably sealed to the outer casing of the gearbox via a second sealing ring.

[0039] In the above technical solution, the lubricating oil, as an essential component, is sealed inside the gearbox housing by the first and second sealing rings, preventing it from overflowing and contaminating the food.

[0040] Preferably, the housing includes a gearbox bushing, a gearbox body, and a gearbox cover connected in sequence, wherein:

[0041] The gearbox bushing is fitted onto the outer periphery of the gear drive shaft, and the first sealing ring is disposed at the end plate of the gearbox bushing.

[0042] The power input end plate is formed by the gearbox cover, and both second sealing rings are disposed on the gearbox cover;

[0043] The gear set is disposed within the space formed by the gearbox body and the gearbox cover, and the gearbox body and the gearbox cover are sealed together by a third sealing ring.

[0044] To facilitate disassembly and installation, the outer casing consists of a gearbox body and a gearbox cover. At this point, a third sealing ring needs to be added between the two to further prevent grease from spilling out and contaminating the food.

[0045] More preferably, the first sealing ring has a first sealing through hole in the middle for the gear drive shaft to pass through, and an annular first sealing groove is provided on the outer periphery of the first sealing ring. The first sealing groove is engaged with the end plate of the gearbox bushing. The first sealing ring not only ensures that the gear drive shaft can pass through, but also enhances the sealing effect through the first sealing groove.

[0046] More preferably, the second sealing ring includes a rigid force-bearing portion and a soft sealing portion surrounding the force-bearing portion; one end of the force-bearing portion receives the power transmitted by the first meat-cutting transmission gear or the second meat-cutting transmission gear, and the other end outputs the power; the sealing portion is sealed to the cover body on the gearbox cover. The force-bearing portion of the second sealing ring is used to bear the force and therefore needs to be made of a rigid material, while the sealing portion achieves lubrication and sealing and needs to be made of a soft material.

[0047] More preferably, the outer periphery of the sealing part is provided with an annular second sealing groove, which engages with the cover body on the gearbox cover, and the second sealing groove enhances the sealing effect through engagement.

[0048] Preferably, the first meat-cutting drive gear and the second meat-cutting drive gear output rotational power through a transmission element.

[0049] More preferably, the two ends of the conductive member are respectively provided with a gear conductive end and a sealed conductive end;

[0050] The gear transmission end is connected to the first meat cutting transmission gear or the second meat cutting transmission gear, and rotates coaxially with the first meat cutting transmission gear or the second meat cutting transmission gear;

[0051] The sealed conductive end is connected to one end of the force-receiving part, and the force-receiving part rotates coaxially with the conductive component.

[0052] More preferably, the force-bearing part is a cylindrical part made of PP or PS, and the sealing part is a ring-shaped part supported by TPE.

[0053] Preferably, the gear drive shaft transmits the input power via a spline.

[0054] The meat cutting machine is equipped with a meat cutting module as described in any of the above technical solutions.

[0055] In summary, the technical solution described in this invention has the following main beneficial effects:

[0056] Compared with the prior art, the technical solution of the present invention provides a meat cutting structure that makes the spacing between each comb tooth and the total width of several comb teeth easy to adjust, and the knife comb assembly structure is easy to disassemble and assemble.

[0057] At the same time, it enables the total spacing of several blades to be adjusted and positioned by the baffle adjustment component after adjustment, so as to adapt to different cutting needs of the cutting board.

[0058] Furthermore, the gearbox in the invention has good sealing performance, which can prevent grease from overflowing and contaminating the food.

[0059] Further or more detailed beneficial effects will be described in conjunction with specific embodiments in the detailed implementation. Attached Figure Description

[0082] The present invention will be further explained in conjunction with the embodiments:

[0083] The core technical problem faced by the technical solution of this application embodiment stems from the inventor's accurate understanding of the prior art. Therefore, how to provide a meat cutting module with adjustable blade and comb spacing is a technical problem that the inventor urgently needs to solve.

[0084] It should be noted that the embodiments do not constitute a limitation on the scope of protection of the claims of this invention. All technical solutions that can be reasonably expected by those skilled in the art based on the technical concepts provided / proved by the embodiments should be covered within the scope of protection of the claims of this invention.

[0085] The specific implementation examples are detailed below:

[0086] Please refer to the attached document. Figures 1-8 The meat cutting module described in this embodiment includes a meat cutting container 4.7, a meat ingredient inlet 4.8, a meat cutting structure, and a gearbox that provides power, wherein:

[0087] The meat cutting container 4.7 provides the space required for meat cutting operations. The meat cutting container 4.7 includes two assembled components, upper and lower. The surface of the upper assembled component is provided with and connected to a meat cutting ingredient inlet 4.8. The meat cutting ingredient inlet 4.8 includes a channel for introducing meat ingredients into the meat cutting container 4.7.

[0088] For the meat-cutting structure described in the embodiment, please first refer to the attached document. Figures 1-6 The meat-cutting structure includes a comb-like part 4.2 and a corresponding cutting edge part 4.3, wherein:

[0089] The comb section 4.2 involved in this embodiment includes two sets of comb tooth assemblies. Each set of comb tooth assemblies includes a comb tooth shaft 4.21 and a row of comb teeth 4.22 that are slidably hooked on the comb tooth shaft 4.21. The two comb tooth shafts 4.21 are mounted on the snap-fit ​​parts of the upper edge of the power input end plate, the cutter baffle 4.4 and the outer end plate 4.5.

[0090] Specifically, the locking part consists of two sets of locking components. Each set of locking components includes a first sealing end locking a, a second sealing end locking b, and a tool baffle locking c. The two first sealing end locking a are spaced apart on the upper edge of the outer end plate 4.5, the two second sealing end locking b are spaced apart on the upper edge of the power input end plate, and the two tool baffle locking c are located on the upper edge of the tool baffle 4.4.

[0091] Each comb shaft 4.21 has its two ends mounted on the first end-sealing bayonet a and the second end-sealing bayonet b, respectively, and one end mounted on the tool baffle bayonet c in the middle. A row of comb teeth 4.22 on each comb shaft 4.21 is located between the second end-sealing bayonet b and the tool baffle bayonet c. The first end-sealing bayonet a, the second end-sealing bayonet b, and the tool baffle bayonet c all have upward-facing openings for the comb shaft 4.21 to enter and exit the assembly. In this embodiment, the bottom of the bayonet has a limiting surface that fits against the outer contour of the comb shaft 4.21 to prevent the comb shaft 4.21 from shaking within the bayonet.

[0092] In this embodiment, the comb teeth 4.22 have a consistent shape and size, thereby unifying the guiding function of the comb and enhancing the stability of the guidance. Each comb tooth 4.22 includes a connecting part 4.221 and a guiding part 4.222. The connecting part 4.221 is provided with a through hole, through which the comb tooth shaft 4.21 passes and is slidably connected to the connecting part 4.221. The through hole has an inner contour that fits and conforms to the surface of the comb tooth shaft 4.21, which can prevent the comb tooth shaft 4.21 from shaking in the through hole. The guiding part 4.222 has a guiding surface with a downward gradually increasing inclination to guide the food to move downward into the cutting area of ​​the blade 4.32.

[0093] Meanwhile, since each comb tooth 4.22 is positioned between two blades 4.32, the position of each comb tooth 4.22 needs to be adjusted synchronously each time the spacing between the blades 4.32 is adjusted, so that there is still one comb tooth 4.22 between every two adjacent blades 4.32 to guide the food downward. In this embodiment, the comb tooth 4.22 is slidably attached to the comb tooth shaft 4.21, which is convenient for adjustment.

[0094] The cutting tool 4.3 involved in this embodiment includes two sets of cutting tool assemblies. Each set of cutting tool assemblies includes a cutting tool shaft 4.31 and a row of blades 4.32 slidably connected to the cutting tool shaft 4.31. Each comb tooth 4.22 is disposed between two adjacent blades 4.32. One end of the cutting tool shaft 4.31 is axially rotatably linked to the power input end plate, and the other end is hinged to the outer end plate 4.5. In this embodiment, all blades 4.32 are circular blades of the same shape and size to form a reasonable cutting area and enhance the stability of cutting. It can also save the cost of manufacturing blades. Furthermore, the two sets of blades 4.32 between the two sets of cutting tool assemblies are staggered along the axial direction of the cutting tool shaft 4.31, which can form an efficient cutting area.

[0095] Please refer to the attached document. Figures 1-2 9-10, the gearbox in this embodiment includes a gear drive shaft 4.11, a gear set 4.12, an output part 4.13, and a first sealing ring 4.14 and a second sealing ring 4.15 that serve a sealing function;

[0096] The gear drive shaft 4.11 transmits the input power via a spline;

[0097] The gear set 4.12 includes a first meat cutting transmission gear 4.121 and a second meat cutting transmission gear 4.122. The first meat cutting transmission gear 4.121 is connected to the aforementioned gear transmission shaft 4.11 and rotates coaxially. The second meat cutting transmission gear 4.122 is connected to the first meat cutting transmission gear 4.121 and rotates in opposite directions.

[0098] The output section 4.13 is disposed on the power input end plate mentioned above. The output section 4.13 includes two sub-output sections 4.131. The two sub-output sections 4.131 are respectively connected to the first meat cutting transmission gear 4.121 and the second meat cutting transmission gear 4.122 and rotate synchronously.

[0099] In a preferred embodiment, the aforementioned tool baffle 4.4 is slidably connected to the tool holder shaft 4.31, and the working area of ​​the two rows of blades 4.32 is formed between the tool baffle 4.4 and the power input end plate;

[0100] The position of the tool baffle 4.4 on the tool holder shaft 4.31 is adjusted by the baffle adjusting component 4.6. In this embodiment, the baffle adjusting component 4.6 includes an adjusting screw 4.61 and an adjusting knob 4.62 that drives the adjusting screw 4.61 to rotate. The adjusting screw 4.61 is screwed into the adjusting screw hole 4.51 opened in the middle of the outer end plate 4.5. One end of the adjusting screw 4.61 located on the inner side of the outer end plate 4.5 abuts against the tool baffle 4.4, and the other end located on the outer side of the outer end plate 4.5 is connected to the adjusting knob 4.62. Furthermore, the abutment point between the adjusting screw 4.61 and the tool baffle 4.4 is located between the two tool holder shafts 4.31, so that the compressive force is evenly applied to the tool baffle 4.4.

[0101] In this embodiment, the comb teeth 4.22 on the comb tooth assembly can slide on the comb tooth shaft 4.21, which facilitates the adjustment of the spacing between each comb tooth 4.22 and the total width of each row of comb teeth 4.22. The total spacing of the several blades 4.32 on the cutting tool assembly can also be adjusted, and after adjustment, they are positioned by the baffle adjustment component 4.6. During positioning, first rotate the adjustment knob 4.62, and adjust the adjustment screw 4.61 through the screw connection structure to push the cutter baffle 4.4 to different positions on the cutting tool shaft 4.31, thereby obtaining different spacing between blades and spacing between comb teeth 4.22 to adapt to different cutting tool requirements.

[0102] Meanwhile, the comb shaft 4.21 is mounted on several bayonets with openings, which facilitates the disassembly and assembly of the comb section 4.2.

[0103] Regarding the assembly structure of the comb section 4.2:

[0104] In a preferred embodiment, a limiting cover d is provided on the opening of the first sealing end a and the second sealing end b to partially cover the opening. The limiting cover d at both ends is used to form a limiting structure at both ends of the comb shaft 4.21 above, preventing the comb shaft 4.21 from moving upward.

[0105] In a further preferred embodiment, the limiting cover d on the opening of the first sealing end a is located on the side of the opening away from the second sealing end b, and the limiting cover d on the opening of the second sealing end b is located on the side of the opening away from the first sealing end a. In this embodiment, the limiting cover d is positioned as far as possible towards both ends to leave relatively ample space and not to obstruct the assembly of the comb shaft 4.21.

[0106] Regarding the assembly structure of the cutting board section 4.3:

[0107] In the preferred embodiment, please refer to the appendix. Figure 7 and 8A variable-pitch elastic plate 4.33 is provided between two adjacent blades 4.32, wherein:

[0108] The variable-pitch elastic plate 4.33 is provided with a variable-pitch connecting through hole 4.331 that is slidably connected to the cutting tool shaft 4.31, and is also provided with a variable-pitch part 4.332 that has an elastic telescoping distance in the axial direction of the cutting tool shaft 4.31. Specifically, the variable-pitch part 4.332 includes two partially spaced partial elastic plates, the two partial elastic plates having ends connected together and a spaced-apart variable-pitch interval 4.332b. The partial elastic plates also have a force-bearing surface 4.332a that abuts against the adjacent blade 4.32. The two force-bearing surfaces 4.332a on the same variable-pitch part 4.332 are spaced apart to form the aforementioned variable-pitch interval 4.332b.

[0109] Each force-bearing surface 4.332a is connected to the adjacent end via a spring-loaded inclined surface 4.332c. When the force-bearing surface 4.332a is subjected to pressure, the spring-loaded inclined surface 4.332c deforms and gives the force-bearing surface 4.332a a spring-loaded force in the opposite direction to the pressure. This spring-loaded force causes the force-bearing surface 4.332a to press tightly against the blade 4.32, preventing the blades 3.32 from becoming loose and deformed, which would be detrimental to cutting.

[0110] In the above technical solution, the variable pitch elastic plate 4.33 not only allows the total spacing of multiple blades 4.32 to be adjusted by the degree of compression of the tool baffle 4.4, but also allows the spacing between adjacent blades 4.32 to be adjusted accordingly. When the degree of compression of the tool baffle 4.4 is large, the variable pitch part 4.332 is compressed, and the total spacing of each row of blades 4.32 and the spacing between adjacent blades 4.32 both become smaller. When the degree of compression of the tool baffle 4.4 is small, the variable pitch part 4.332 recovers its deformation under the action of its own elastic force, and the total spacing of each row of blades 4.32 and the spacing between adjacent blades 4.32 both increase.

[0111] In one example, the variable-pitch elastic plate 4.33 is formed by connecting two elastic rings with three connection points between them. The variable-pitch portion 4.332 is formed between two adjacent connection points. This structure is relatively simple and easy to manufacture into the variable-pitch elastic plate 4.33 product. At the same time, the three connection points form a limiting structure for the inner diameter of the variable-pitch connecting through hole 4.331. That is, in this embodiment, when the force-bearing surface 4.332a is compressed, the variable-pitch connecting through hole 4.331 will not expand accordingly. When the force-bearing surface 4.332a decreases and the variable-pitch interval 4.332b widens, the variable-pitch connecting through hole 4.331 will not decrease accordingly. Thus, the variable-pitch elastic plate 4.33 always remains sleeved on the tool holder shaft 4.31 and will not loosen or wobble in the radial direction.

[0112] In a preferred embodiment, in the gearbox structure, the gear drive shaft 4.11 is rotatably and sealingly connected to the gearbox housing via a first sealing ring 4.14, and the two sub-output parts 4.131 are rotatably and sealingly connected to the gearbox housing via a second sealing ring 4.15.

[0113] In the technical solution of this embodiment, the output part 4.13 of the gearbox causes the cutting board to rotate and cut the food under the drive of the gear transmission structure.

The rigid material is a cylindrical part made of PP or PS, and the soft material is a ring-shaped part supported by TPE. The force-bearing part 4.151 of the second sealing ring 4.15 is used to bear the force, so it needs to be made of rigid material. The sealing part 4.152 realizes lubrication and sealing, so it needs to be made of soft material.

[0124] In this embodiment, the second sealing ring 4.15 has a force-receiving part 4.151 with a protruding locking platform at one end and a recessed locking blind hole at the other end, which is the sub-output part 4.131 mentioned in the above embodiment.

[0125] In the preferred embodiment, please refer to the following: Figure 12 The first meat-cutting transmission gear 4.121 and the second meat-cutting transmission gear 4.122 output rotational power through the transmission member 4.10.

[0126] The gear transmission end 4.101 is connected to the first meat cutting transmission gear 4.121 or the second meat cutting transmission gear 4.122 and rotates coaxially with the first meat cutting transmission gear 4.121 or the second meat cutting transmission gear 4.122; the sealing transmission end 4.102 is connected to one end of the force-receiving part 4.151 of the second sealing ring 4.15 mentioned above, and the force-receiving part 4.151 rotates coaxially with the transmission member 4.10.

[0127] In the technical solution of this embodiment, the gear set 4.12 transmits rotation to the second sealing ring 4.15 through the transmission component 4.10. After long-term use and wear, the transmission component 4.10 is easy to replace, and the second sealing ring 4.15 does not need to be replaced frequently.
