Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to a meat cutting module and a meat cutting and preparing machine. Background Art

[0002] For all kinds of operations in the kitchen, food preparation before cooking has always been an indispensable link. For Chinese cooking, which has a variety of cooking methods and a wide variety of ingredients, the food preparation links are even more diverse. Among them, cutting meat into blocks or strips is also a common food preparation operation link. For electric meat cutting modules, a knife comb is usually used as a guide component to guide the ingredients into the cutting area, and then the ingredients are cut by two sets of arranged blades;

[0003] However, the installation structure of the knife comb and the blade is often fixed inside the meat cutting module. As a result, these knife combs and blades can only be used in this fixed specification meat cutting module. When the distance between the knife comb and the blade is changed according to the preparation requirements, the entire meat cutting structure needs to be replaced, which is time-consuming and labor-intensive, and the material cost is high. Summary of the invention

[0004] In order to solve the above technical problems, the present application further improves the meat cutting structure inside the meat cutting module, so as to solve the above technical problems and obtain a meat cutting module with adjustable spacing between blades. One of the purposes of the present invention is to provide a meat cutting module, and the second purpose is to provide a corresponding cutting machine.

[0011] In the above technical solution, the comb teeth can slide on the comb tooth shaft rod, which is convenient for adjusting the spacing between each comb tooth and the total width of a plurality of comb teeth. The total spacing of a plurality of blades on the knife assembly can be adjusted. Since each comb tooth is arranged 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 arranged between each two adjacent blades to guide the food to move downward. The comb teeth in the technical solution of the present invention are slidably hung on the comb tooth shaft rod, which is just convenient for adjustment.

[0012] The output part of the gear box is driven by the gear transmission structure to rotate the knife to cut the food.

[0017] The clamping part includes at least two groups of bayonet assemblies matching the number of the comb tooth assemblies, each group of the bayonet assemblies includes a first end-sealing bayonet at one end, a second end-sealing bayonet at the other end, and a tool baffle bayonet located between the first end-sealing bayonet and the second end-sealing bayonet, and a plurality of the comb teeth are arranged between the second end-sealing bayonet and the tool baffle bayonet;

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

[0019] The first end-sealing bayonet, the second end-sealing bayonet and the tool baffle bayonet all have an opening facing upward for the comb tooth shaft to enter and exit, and the comb tooth shaft is mounted on several bayonet ports of the same bayonet assembly.

[0020] In the above technical solution, the comb tooth shaft is mounted on a plurality of bayonet holes with openings, which is convenient for disassembly and assembly.

[0021] Preferably, a limiting cover which at least partially covers the opening is provided on the openings of the first end sealing snap-in and the second end sealing snap-in, and the limiting covers provided at both ends are used to form a limiting structure at both ends of the comb tooth shaft rod above to prevent the comb tooth shaft rod from moving upward.

[0022] Preferably, the limit cover on the opening of the first end-sealing bayonet partially covers the opening, and the covering position is located on the side of the opening away from the second end-sealing bayonet; the limit cover on the opening of the second end-sealing bayonet partially covers the opening, and the covering position is located on the side of the opening away from the first end-sealing bayonet. The setting position of the limit cover in this technical solution is as biased as possible to the two ends to leave relatively ample space and not hinder the assembly of the comb tooth shaft.

[0023] Preferably, the tool baffle plate snap-in is arranged at the upper edge of the tool baffle plate, and the tool baffle plate has an adjustment range that can move along the axial direction of the comb tooth shaft.

[0024] Preferably, the bottom of the bayonet has a limiting surface that at least partially fits the outer contour of the comb tooth shaft to prevent the comb tooth shaft from shaking in the bayonet.

[0025] Preferably, the comb teeth include a connecting portion and a guiding portion, the connecting portion is movably connected to the comb tooth shaft, and the guiding portion has a guiding surface with an inclination that gradually increases downward, so as to guide the food to move downward into the cutting area.

[0026] Further preferably, a through hole is provided on the connecting portion, and the comb tooth shaft passes through the through hole to be slidably connected with the connecting portion.

[0027] Further preferably, the through hole has an inner contour that is matched and fits with the surface of the comb tooth shaft, so as to prevent the comb tooth shaft from shaking in the through hole.

[0028] Preferably, the plurality of comb teeth have consistent shapes and sizes, thereby unifying the guiding function of the knife comb and enhancing the guiding stability.

[0043] The gear set is arranged in a space formed by the gear box body and the gear box cover, and the gear box body and the gear box cover are sealed and connected via a third sealing ring.

[0044] In order to facilitate disassembly and installation, the outer shell is composed of a gear box body and a gear box cover. At this time, it is necessary to add a third sealing ring between the two to further prevent grease from overflowing and contaminating the food.

[0047] Further preferably, an annular second sealing groove is provided on the outer periphery of the sealing portion, and the second sealing groove is snap-fitted with the cover body on the gear box cover, and the second sealing groove enhances the sealing effect by snapping.

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

[0049] Further preferably, the two ends of the transmission member are respectively provided with a gear transmission end and a sealing transmission end;

Therefore, how to provide a meat cutting module with adjustable blade and knife 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 protection scope of the claims of the present invention. According to the technical concepts provided / proven by the embodiments, all technical solutions that can be reasonably anticipated by technicians in the relevant technical field should be included in the protection scope of the claims of the present invention.

[0085] The embodiments are described in detail as follows:

[0086] Please refer to the attached Figures 1 to 8 The meat cutting module described in this embodiment includes a meat cutting container 4.7, a meat cutting material introduction member 4.8, a meat cutting structure and a gear box for providing power, wherein:

The upper component is provided with a meat cutting material introduction member 4.8 on its surface and is connected thereto. The meat cutting material introduction member 4.8 includes a passage for introducing meat ingredients into the meat cutting container 4.7.

[0088] Please refer to the attached Figures 1 to 6 The meat cutting structure comprises a knife comb part 4.2 and a knife chopping part 4.3 matched therewith, wherein:

[0089] The blade comb part 4.2 involved in this embodiment includes two groups of comb tooth assemblies, each group of comb tooth assemblies includes a comb tooth shaft rod 4.21 and a row of comb teeth 4.22 slidably mounted on the comb tooth shaft rod 4.21, and the two comb tooth shaft rods 4.21 are mounted on the clamping parts of the upper edge of the power input end plate, the blade baffle plate 4.4 and the outer end plate 4.5;

[0090] Specifically, the clamping part is composed of two groups of bayonet components, each group of bayonet components includes a first end-sealing bayonet a, a second end-sealing bayonet b and a tool baffle bayonet c, the two first end-sealing bayonet a are arranged at intervals on the upper edge of the outer end plate 4.5, the two second end-sealing bayonet b are arranged at intervals on the upper edge of the power input end plate, and the two tool baffle bayonet c are arranged on the upper edge of the tool baffle 4.4;

[0091] The two ends of each comb-tooth shaft rod 4.21 are respectively mounted on the first end-sealing bayonet a and the second end-sealing bayonet b, and there is a place in the middle mounted on the tool baffle bayonet c. A row of comb teeth 4.22 on each comb-tooth shaft rod 4.21 is arranged 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 an opening facing upward for the comb-tooth shaft rod 4.21 to enter and exit for assembly. In this embodiment, the bottom of the bayonet has a limiting surface that fits the outer contour of the comb-tooth shaft rod 4.21 to prevent the comb-tooth shaft rod 4.21 from shaking in the bayonet;

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

[0093] At the same time, since each comb tooth 4.22 is arranged between two blades 4.32, each time the spacing between the blades 4.32 is adjusted, the position of each comb tooth 4.22 needs to be adjusted synchronously to continue to maintain a comb tooth 4.22 between every two adjacent blades 4.32 to guide the food to move downward. In the embodiment, the comb teeth 4.22 are slidably hung on the comb tooth shaft 4.21, which is just convenient for adjustment.

[0094] The knife-cutter part 4.3 involved in this embodiment includes two groups of knife-cutter assemblies, each group of knife-cutter assemblies includes a knife-cutter shaft rod 4.31 and a row of blades 4.32 slidably connected to the knife-cutter shaft rod 4.31, each comb tooth 4.22 is arranged between two adjacent blades 4.32, one end of the knife-cutter shaft rod 4.31 is axially rotated and linked to the power input end plate, and the other end is hinged on the outer end plate 4.5. All blades 4.32 in this embodiment are circular blades of the same shape and size to form a reasonable cutting area, enhance cutting stability, and save the cost of preparing blades. In addition, the two groups of blades 4.32 between the two groups of knife-cutter assemblies are staggered along the axial direction of the knife-cutter shaft rod 4.31, which can form an efficient cutting area.

[0095] Please refer to the attached Figures 1-2 9-10, the gear box in this embodiment includes a gear transmission 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 for sealing;

[0096] The gear transmission shaft 4.11 transmits the input power through the spline;

[0097] The gear set 4.12 comprises 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 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 part 4.13 is arranged on the power input end plate, and includes two sub-output parts 4.131, which are respectively connected to the first meat cutting transmission gear 4.121 and the second meat cutting transmission gear 4.122 for synchronously rotating output.

[0099] In a preferred embodiment, the above-mentioned tool baffle 4.4 is slidably connected to the tool shaft 4.31, and a working area of ​​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 shaft 4.31 is adjusted by a baffle adjusting member 4.6. The baffle adjusting member 4.6 in this embodiment includes an adjusting screw 4.61 and an adjusting knob 4.62 for driving the adjusting screw 4.61 to rotate. The adjusting screw 4.61 is screwed into an adjusting screw hole 4.51 provided 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 above-mentioned adjusting knob 4.62. In addition, the abutment between the adjusting screw 4.61 and the tool baffle 4.4 is located between the two tool shafts 4.31, so that the compression force acts evenly on the tool baffle 4.4.

[0101] In the technical solution of this embodiment, the comb teeth 4.22 on the comb teeth assembly can slide on the comb teeth shaft 4.21, so as to adjust the spacing between the comb teeth 4.22 and the total width of each row of comb teeth 4.22. The total spacing of the plurality of blades 4.32 on the knife assembly can also be adjusted, and after adjustment, they are positioned by the baffle adjusting member 4.6. When positioning, the adjusting knob 4.62 is first rotated, and the adjusting screw 4.61 is adjusted through the screw connection structure to push the tool baffle 4.4 to different positions of the knife shaft 4.31, thereby obtaining different spacings between the blades and the spacing between the comb teeth 4.22 to meet different knife cutting requirements;

[0102] At the same time, the comb tooth shaft 4.21 is mounted on a plurality of bayonet holes with openings, so as to facilitate the disassembly and assembly of the blade comb part 4.2.

[0103] As for the assembly structure of the blade comb part 4.2:

[0104] In a preferred embodiment, a limiting cover d partially covering the openings is provided on the openings of the first end sealing snap-in a and the second end sealing snap-in b. The limiting covers d provided at both ends are used to form limiting structures at both ends of the comb tooth shaft 4.21 above to prevent the comb tooth shaft 4.21 from moving upward.

[0105] In a further preferred embodiment, the covering position of the limit cover d on the opening of the first end sealing bayonet a is located on the side of the opening away from the second end sealing bayonet b, and the covering position of the limit cover d on the opening of the second end sealing bayonet b is located on the side of the opening away from the first end sealing bayonet a. The setting position of the limit cover d in this embodiment is as biased as possible to the two ends to leave relatively ample space and not hinder the assembly of the comb tooth shaft 4.21.

[0106] For the assembly structure of the knife and fork part 4.3:

[0107] In the preferred embodiment, please refer to the attached Figure 7 and 8, a variable pitch elastic sheet 4.33 is provided between two adjacent blades 4.32, wherein:

[0108] The variable pitch elastic sheet 4.33 is provided with a variable pitch connection through hole 4.331 slidably connected to the knife shaft 4.31, and is also provided with a variable pitch portion 4.332 having an elastic telescopic spacing in the axial direction of the knife shaft 4.31. Specifically, the variable pitch portion 4.332 includes two partially spaced apart local elastic sheets, the two local elastic sheets having ends connected together and spaced-apart variable pitch intervals 4.332b, and the local elastic sheet also has a force-bearing surface 4.332a abutting against the adjacent blade 4.32, and the two force-bearing surfaces 4.332a on the same variable pitch portion 4.332 are spaced apart to form the above-mentioned variable pitch interval 4.332b;

[0109] Each force-bearing surface 4.332a is connected to the adjacent end portion via a rebound slope 4.332c. When the force-bearing surface 4.332a is subjected to pressure, the rebound slope 4.332c is deformed and causes the force-bearing surface 4.332a to have a rebound force in the opposite direction to the pressure. The rebound force causes the force-bearing surface 4.332a to press the blade 4.32 tightly, preventing each blade 3.32 from loosening and deforming, which is not conducive to cutting.

[0110] In the above technical solution, the variable pitch elastic sheet 4.33 not only allows the total spacing of the multiple blades 4.32 to be adjusted by the compression degree of the tool baffle 4.4, but also allows the spacing between adjacent blades 4.32 to be adjusted accordingly. When the compression degree of the tool baffle 4.4 is large, the variable pitch portion 4.332 is compressed, and the total spacing of each row of blades 4.32 and the spacing between adjacent blades 4.32 are both reduced. When the compression degree of the tool baffle 4.4 is small, the variable pitch portion 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 are both increased.

[0111] In one example, the variable pitch elastic sheet 4.33 is formed by connecting two elastic ring sheets, and there are three connection points between the two elastic ring sheets. The above-mentioned variable pitch part 4.332 is formed between two adjacent connection points. This structure is relatively simple and easy to produce to form a variable pitch elastic sheet 4.33 product. At the same time, the three connection points constitute 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 by force, the variable pitch connecting through hole 4.331 will not expand accordingly. When the force-bearing surface 4.332a is reduced and the variable pitch interval 4.332b becomes wider, the variable pitch connecting through hole 4.331 will not decrease accordingly, and thus the variable pitch elastic sheet 4.33 always remains sleeved on the knife shaft 4.31 and will not loosen / shake in the radial direction.
