Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, specifically to a meat cutting module and a meat cutting machine. Background Technology

[0002] Existing meat slicers use a scissor-like cutting principle to cut meat. Two cutting rods are installed within the machine frame, rotating relative to each other. The blades on the two cutting rods interlock to form the cutting area. Multiple blades mounted side-by-side on the same cutting rod can achieve batch cutting of meat products, resulting in very high cutting efficiency. For details, please refer to Chinese Utility Model Patent No. CN201921681481.1 (Publication No. CN210610851U), entitled "A Meat Slicer".

[0003] Most meat slicers use fixed combs to guide the food being cut, allowing it to slide out of the machine along the guide combs and preventing meat scraps from getting tangled on the shaft. However, the design of the combs also brings some problems. On the one hand, fine residues and meat scraps can slide into the back (outer side) of the combs and accumulate. On the other hand, the presence of the combs means that during normal cleaning, when water is sprayed from above, the water flow cannot reach the back of the combs or the area on the back of the combs. Over time, this can lead to food accumulation, spoilage, and foul odors, seriously affecting food hygiene.

[0004] When cleaning is needed, the comb teeth need to be manually moved back and forth to ensure thorough cleaning. However, this requires manual operation each time, which is inefficient and results in unsatisfactory cleaning. If the comb teeth are driven to move by a drive mechanism, an additional drive mechanism is required, which makes the structure complex.

[0005] In addition, for meat slicers with comb teeth, firstly, there will still be gaps between the comb teeth and the blades, which will allow small pieces of meat to slide into the back of the comb teeth and then get tangled on the shaft; secondly, the comb teeth are generally installed on the top of the blade holder and inserted between the blades from top to bottom. When cleaning, the upper part of the comb teeth will block the cleaning water to a certain extent, creating a certain blind spot for cleaning. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to provide a meat cutting module that is easy to clean thoroughly and does not require the introduction of an additional drive mechanism, in light of the current state of the prior art.

[0007] The second technical problem to be solved by the present invention is to provide a meat cutting module that can prevent small pieces of meat that have been cut into the outside of the comb teeth from getting tangled on the rotating shaft.

[0008] The third technical problem to be solved by the present invention is to provide a meat cutting module that can avoid the comb teeth from blocking the water path for cleaning.

[0009] The fourth technical problem to be solved by the present invention is to provide a meat slicer that incorporates the above-mentioned meat slicing module.

[0010] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a meat cutting module, comprising:

[0011] Knife holder;

[0012] Two sets of blades, each set of blades including a rotating shaft and at least two blades spaced apart along the axis of the rotating shaft, the rotating shafts of the two sets of blades are arranged side by side, and the ends of each rotating shaft are mounted on the blade holder in a manner that allows them to rotate around their own axis, a gap is formed between two adjacent blades in the same set of blades, the blades of the two sets of blades are arranged alternately, and corresponding blades in the two sets of blades are in close contact with each other.

[0013] Two sets of comb teeth, each corresponding to one of the blade sets, each set including a rack corresponding to one of the gaps, with at least a portion of each rack located within the corresponding gap, and a material guiding channel formed between corresponding racks in the two sets of comb teeth; and

[0014] The drive mechanism is used to drive the rotating shafts of the two sets of blades to rotate in opposite directions, so that the corresponding blades in the two sets of blades rotate relative to each other and cooperate to cut the food.

[0015] The characteristic feature is that the rack is mounted on the rotating shaft in a manner that allows it to rotate around the axis of the rotating shaft, and at least one side of the rack is in frictional contact with the opposite surface of the adjacent blade, so that the corresponding racks in the two sets of comb teeth can achieve relative opening and closing under the action of friction as they deflect with the blade.

[0016] To achieve consistent deflection of each rack, the racks have protrusions extending beyond the corresponding gaps, with the protrusions of adjacent racks interconnected. Since the racks are connected to form a single unit, on the one hand, under the friction of the blades, each rack can deflect synchronously; on the other hand, under the interaction force of the racks, at least one side of each rack can be pressed tightly against the adjacent blade, providing sufficiently large frictional force.

[0017] In order to allow the two sets of comb teeth to deflect within a set angular range, it also includes...

[0018] A first limiting structure is used to limit the extreme positions of the two sets of comb teeth opening outward; and;

[0019] The second limiting structure is used to limit the extreme position of the two sets of comb teeth closing inward.

[0020] To limit the outward opening of the two sets of comb teeth to their extreme positions, the first limiting structure includes:

[0021] A first limiting part is provided on the tool holder; and

[0022] The first mating part is provided on the comb teeth and is used to perform a limiting engagement with the first limiting part.

[0023] When the first mating part of the comb teeth deflects outward to the position of the first limiting part, the first mating part abuts against the inner side of the first limiting part, so that the two sets of comb teeth overcome the frictional force and remain in the open state.

[0024] To limit the extreme position of the two sets of comb teeth closing inward, the second limiting structure includes:

[0025] A second limiting part is provided on the aforementioned tool holder; and

[0026] The second mating part is provided on the comb teeth and is used to perform a limiting engagement with the second limiting part.

[0027] When the second mating part of the comb teeth deflects inward to the position of the second limiting part, the second mating part abuts against the outside of the second limiting part, so that the two sets of comb teeth overcome the frictional force and remain in the closed state.

[0028] In order to limit the extreme position of the two sets of comb teeth closing inward, the corresponding protrusions of the two sets of comb teeth have serrated portions that can mesh with each other on their opposite surfaces, and the serrated portions of the two sets of comb teeth form the second limiting structure.

[0029] When the serrated portion of the comb teeth deflects inward to the position of the serrated portion of another toothed rack, the corresponding serrated portions of the two sets of comb teeth mesh with each other, so that the two sets of comb teeth overcome the frictional force and remain in the closed state.

[0030] To facilitate the interconnection of the racks, each set of comb teeth also includes a connecting rod, and the protruding part of each rack is connected to the connecting rod.

[0031] To further address the second technical problem mentioned above, each of the racks has a surrounding portion that surrounds the outer periphery of the rotating shaft, and the rotating shaft is rotatable relative to the surrounding portion.

[0032] To further address the third technical problem mentioned above, the top end of the rack has the aforementioned surrounding portion, and the bottom end of the rack extends downward.

[0033] To facilitate the smooth rinsing of the comb teeth by the water flow from above, the side of the comb facing the other comb has a first guide surface, and the side of the comb facing away from the other comb has a second guide surface. The first guide surface and the second guide surface smoothly transition to the outer peripheral surface of the surrounding part.

[0034] To reduce the area of ​​blind spots in cleaning, the distance between the first guide surface and the second guide surface gradually decreases from top to bottom.

[0035] To facilitate the limitation of the spacing between two adjacent blades, each blade set also includes a limiting block that corresponds one-to-one with the gap. The limiting block is located in the corresponding gap and abuts against the opposite surface of the adjacent blade.

[0036] To facilitate the stable installation of the limiting block and the surrounding part, the limiting block is annular and is sleeved on the rotating shaft, and the surrounding part of the rack is annular and is sleeved on the limiting block.

[0037] To drive the shafts of the two sets of cutters to rotate in opposite directions, the drive mechanism includes:

[0038] Two meshing gears correspond one-to-one with the aforementioned rotating shafts, and each gear is coaxially mounted at the end of its corresponding rotating shaft; and

[0039] A drive unit, connected to one of the gears, for driving the gear to rotate about its own axis.

[0040] To facilitate the feeding and discharging of ingredients, the inside of the knife holder is formed with a receiving cavity. The top and bottom of the knife holder are respectively provided with a feeding port and a discharging port. The two sets of knife groups are housed in the receiving cavity, and the discharging port is directly opposite the intersection of the blades in the two sets of knife groups.

[0041] The technical solution adopted by the present invention to solve the above-mentioned fourth technical problem is: a meat slicer, characterized in that: it applies the above-mentioned meat slicer module.

[0042] Compared with the prior art, the advantages of the present invention are as follows:

[0043] (1) By mounting the rack on the rotating shaft in a way that it can rotate around the axis of the rotating shaft, and at least one side of the rack is in frictional contact with the opposite surface of the adjacent blade, the corresponding racks in the two sets of comb teeth can be deflected by the blade under the action of friction to achieve relative opening and closing. On the one hand, when cleaning is required, the power output direction can be repeatedly changed by the drive mechanism to drive the two sets of comb teeth to open and close within the set angle range, which is convenient for thorough cleaning. On the other hand, the rack is deflected by the friction of the blade, without the need to introduce an additional drive mechanism, and the structure is simple.

[0044] (2) The deflection angle range of the comb teeth can be controlled by a simple mechanical structure, without the need to introduce a complex control system, and the structure is simple;

[0045] (3) Since the rack is surrounded by the shaft through the enclosing part, it effectively isolates the shaft and prevents small meat scraps that have entered the outside of the comb teeth from getting wrapped around the shaft.

[0046] (4) Since the surrounding part is located at the top of the comb teeth and there is an open space above the rotating shaft, the water flow can smoothly rinse from top to bottom without the comb teeth blocking the water path. Attached Figure Description

[0056] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0057] Example 1:

[0058] like Figures 1 to 6The figure shows a first preferred embodiment of the meat slicer of the present invention. The meat slicer includes a housing (not shown) and a meat slicing module 2 disposed inside the housing.

[0059] The outer shell generally serves to protect the meat cutting module 2.

[0060] The meat cutting module 2 is located inside the base 11. The meat cutting module 2 includes a blade holder 21, a blade assembly 22, comb teeth 23, and a drive mechanism 24.

[0061] The tool holder 21 has an internal cavity 211, an open top for a feed inlet 212, and a long, narrow discharge outlet 213 extending in the front-to-back direction at the bottom center of the tool holder 21.

[0062] There are two sets of blade assemblies 22, respectively housed on the left and right sides of the aforementioned accommodating cavity 211. Each set of blade assemblies 22 includes a rotating shaft 221, blades 222, and a limiting block 223. Specifically, the rotating shafts 221 of the two sets of blade assemblies 22 are arranged side by side, both extending in the front-rear direction, and the front and rear ends of each rotating shaft 221 are rotatably connected to the front and rear side walls of the blade holder 21, respectively. There are at least two blades 222, which are arranged at intervals along the axial direction of the rotating shaft 221. The plane of each blade 222 is perpendicular to the axis of the rotating shaft 221 and can be movably fitted around the outer periphery of the rotating shaft 221. A gap 2220 is formed between adjacent blades 222 of the same set of blade assemblies 22. The blades 222 are arranged in an alternating pattern, and the corresponding blades 222 in the two sets of blade groups 22 are in close contact with each other. The discharge port 213 is directly opposite the intersection of the blades 222 in the two sets of blade groups 22. The limiting block 223 is annular and can be movably fitted around the outer periphery of the rotating shaft 221. It corresponds one-to-one with the gap 2220. Each limiting block 223 is located in the corresponding gap 2220 and abuts against the opposite surface of the adjacent blades 222. It is used to limit the width of the gap 2220 between two adjacent blades 222.

[0063] There are two sets of comb teeth 23, corresponding one-to-one with the aforementioned blade sets 22. Each set of comb teeth 23 includes a connecting rod 231 and a rack 232. Specifically, the rack 232 corresponds one-to-one with the aforementioned gaps 2220. Each rack 232 is at least partially located in the corresponding gap 2220, and a guide channel 2320 is formed between the corresponding racks 232 in the two sets of comb teeth 23. In this embodiment, the top end of each rack 232 has a surrounding portion 2321, which is annular and rotatably fitted around the outer periphery of the limiting block 223. The bottom end of the rack 232 extends downward and outward into the corresponding gap 2220 to form a protruding portion 2322; the rack 232 faces... A first guide surface 2323 is provided on the inner side (or front side) of the other rack 232, and a second guide surface 2324 is provided on the outer side (or back side) of the rack 232 facing away from the other rack 232. The first guide surface 2323 and the second guide surface 2324 smoothly transition to the outer peripheral surface of the surrounding portion 2321, and the distance between the first guide surface 2323 and the second guide surface 2324 gradually decreases from top to bottom; the connecting rod 231 is connected to the bottom end of the protrusion 2322 of each rack 232. The above-mentioned comb tooth 23 design has the following advantages: First, since the surrounding part 2321 surrounds the rotating shaft 221, it effectively isolates the rotating shaft 221, preventing small meat scraps that have entered the outer side of the comb tooth 23 from getting tangled on the rotating shaft 221; Second, since the surrounding part 2321 is located at the top of the comb tooth 23, there is an open space above the rotating shaft 221, allowing water to flow smoothly from top to bottom without the comb tooth 23 obstructing the water path; Third, since the first guide surface 2323 and the second guide surface 2324 smoothly transition to the outer peripheral surface of the surrounding part 2321, the cleaning water flow above smoothly washes the space inside and outside the comb tooth 23 along the guide surface; Fourth, since the distance between the first guide surface 2323 and the second guide surface 2324 gradually decreases from top to bottom, the contact area between the blade 222 and the toothed bar 232 can be minimized, thereby reducing the area of ​​cleaning dead corners.

[0064] The drive mechanism 24 is mounted on the rear side of the blade holder 21 and includes gears 241 and a drive element (not shown in the figure). Specifically, there are two gears 241, corresponding one-to-one with the aforementioned rotating shafts 221. Each gear 241 is coaxially mounted at the rear end of the corresponding rotating shaft 221, and the two gears 241 mesh with each other. The drive element is connected to one of the gears 241 to drive the gear 241 to rotate around its own axis. When the drive element is activated, the two gears 241 drive the two rotating shafts 221 to rotate in opposite directions (the rotating shaft 221 on the right rotates counterclockwise, and the rotating shaft 221 on the left rotates clockwise), so that the corresponding blades 222 in the two sets of blades 22 rotate relative to each other and cooperate to cut the meat.

[0065] In this embodiment, the two sides of the rack 232 are in frictional contact with the opposing surfaces of the adjacent blades 222, so that the corresponding racks 232 in the two sets of comb teeth 23 can deflect relative to each other within a set angle range under the action of friction. Since each rack 232 is connected by a connecting rod 231 to form a single piece, each rack 232 can deflect synchronously under the friction of the blades 222, and under the action of the interaction force of each rack 232, at least one side of the rack 232 can be pressed tightly against the adjacent blades 222, providing a sufficiently large frictional force.

[0066] Since the comb teeth 23 are driven by friction, the extreme positions of the two sets of comb teeth 23 opening outward and closing inward can be easily limited by setting the first limiting structure and the second limiting structure, respectively.

[0067] In this embodiment, first limiting portions 214 are formed on the left and right sides of the discharge port 213, and the front and rear sides of the connecting rod 231 have downwardly extending stop bars 2311. The first limiting portions 214 and the stop bars 2311 constitute the aforementioned first limiting structure. Second limiting portions 215 are formed on the front and rear sides of the discharge port 213, and the bottom end of each stop bar 2311 has an outwardly protruding stop block 2312. The second limiting portions 215 and the stop blocks 2312 constitute the aforementioned second limiting structure. Figure 3 As shown, when the stop bar 2311 of the comb teeth 23 deflects outward to the position of the first limiting part 214, the stop bar 2311 abuts against the inner side of the first limiting part 214, so that the two sets of comb teeth 23 remain open against the action of friction; as Figure 6 As shown, when the stop block 2312 of the comb tooth 23 deflects inward to the position of the second limiting part 215, the stop block 2312 abuts against the outside of the second limiting part 215 so that the two sets of comb teeth 23 overcome the frictional force and remain in the closed state.

[0068] Example 2:

[0069] like Figures 7 to 9 The image shows a second preferred embodiment of the meat slicer of the present invention. The difference from Embodiment 1 is that:

[0070] In this embodiment, the first limiting part 214 of the tool holder 21 and the protruding part 2322 of the comb teeth 23 form the aforementioned first limiting structure. The opposing surfaces of the protruding parts 2322 of the corresponding racks 232 in the two sets of comb teeth 23 have mutually meshing serrated parts 2325. The serrated parts 2325 of the two sets of comb teeth 23 form the aforementioned second limiting structure. Figure 7 As shown, when the protruding portion 2322 of the comb teeth 23 deflects outward to the position of the first limiting portion 214, the protruding portion 2322 abuts against the inner side of the first limiting portion 214, so that the two sets of comb teeth 23 remain open against the action of friction; as Figure 9 As shown, when the serrated portion 2325 of the comb tooth 23 deflects inward to the position of the serrated portion 2325 of the other rack 232, the corresponding serrated portions 2325 of the two sets of comb teeth 23 mesh with each other so that the two sets of comb teeth 23 overcome the frictional force and remain in the closed state.

[0071] Taking Example 1 as an example, the working principle of this example is as follows:

[0072] (1) When meat needs to be cut, the meat pieces can be put into the feed inlet 212. The meat pieces fall under the action of gravity, such as... Figure 3 As shown, when the drive mechanism 24 outputs positive power, the rotating shaft 221 on the right rotates counterclockwise and the rotating shaft 221 on the left rotates clockwise. The relatively rotating blades 222 cooperate with each other to cut the meat into slices. At the same time, the two sets of comb teeth 23 deflect outward to the open state under the action of friction with the blades 222. Under the guidance of the comb teeth 23, the slices of meat in the gap 2220 gradually separate from the blades 222 and are output through the discharge port 213, thus obtaining the cut meat slices.

[0073] (2) When cleaning is required, the meat cutting module 2 can be rinsed from top to bottom with cleaning water;

[0074] When the drive mechanism 24 outputs positive power, such as Figure 3 As shown, the two sets of comb teeth 23 are deflected outward to the open state under the action of friction, and the downward water flow effectively washes the blade set 23 and the inner side of the comb teeth 23.

[0075] When the drive mechanism 24 outputs reverse power, such as Figure 6 As shown, the two sets of comb teeth 23 deflect inward with the blade 222 under the action of friction to close up, thereby opening the outer area of ​​the comb teeth 23. The cleaning water flow above washes from top to bottom along the outer space, and at the same time the wall of the receiving cavity 211 is also cleaned. The residue inside the blade holder 21 is also washed down with the water flow.

[0076] By repeatedly changing the power output direction through the drive mechanism 24, the two sets of comb teeth 23 can be driven to open and close within a set angle range, which facilitates thorough cleaning.
