Description

Technical Field

[0001] The invention relates to the technical field of kitchen equipment, in particular to a kitchen cutting and preparing machine. Background Art

[0002] In the general food processing field, some bagged foods are processed into slices or filaments and packaged for sale. When processing food manually, a kitchen knife is needed. However, due to its small size and small processing capacity, the efficiency of vegetable processing is too low, and it may hurt fingers if used carelessly. Especially when the processing volume is large, the kitchen knife is also very impractical, not only inefficient but also easy to damage, wasting a lot of manpower and material resources.

[0003] Therefore, some kitchen cutting and preparing machines have appeared on the market, such as the Chinese utility model patent "A vegetable and meat cutting machine" with patent application number CN202022010469.7 (publication number CN213107202U), which discloses a kitchen cutting and preparing machine integrating vegetable cutting and meat cutting modules.

[0004] The existing vegetable cutting module is mainly composed of a driving component and a cutting component. The driving component is used to drive the cutting component to rotate and cut the food. The cutting shape mainly depends on the design of the cutting component. For example, the Chinese utility model patent "A vegetable cutter blade cutting component and a small vegetable cutter" with patent application number CN202122205562.8 (publication number CN215743873U) discloses a cutting component with a slicing function, and the Chinese utility model patent "A shredding blade" with patent application number CN202123432673.9 (publication number CN216505289U) discloses a cutting component with a shredding function.

[0005] However, for the vegetable cutting module, the same set of cutting components can only be used to cut ingredients of one specification, but cannot be used to cut ingredients of two specifications. This can only be achieved by replacing the entire set of cutting components or by replacing the knives individually, which is inconvenient to operate.

[0006] The existing meat cutting module uses the cutting blade area principle similar to scissors to achieve meat cutting. Two cutting rods are arranged in the meat cutting machine frame. The two cutting rods rotate relative to each other, and the blades of the two cutting rods are staggered to form a cutting blade area. Multiple blades installed in parallel on the same cutting rod can achieve batch cutting of meat food with very high cutting efficiency. For details, please refer to the Chinese utility model patent "A Meat Cutting Machine" with patent application number CN201921681481.1 (publication number CN210610851U).

[0007] However, in the existing meat cutting module, the cutting knife group can only cut meat slices of one thickness. If meat slices of different thicknesses need to be cut, the traditional solution is to replace the knife groups of different specifications. However, the replacement of the knife group is very dangerous, it is easy to cut the operator, and it is time-consuming and labor-intensive.

[0008] In addition, in the existing kitchen cutting machines, the vegetable cutting module requires high speed and low torque, while the meat cutting module requires low speed and high torque. Therefore, different driving mechanisms are required to drive the rotating shafts of the vegetable cutting module and the meat cutting module respectively to meet different speed and torque requirements. The structure is complex and occupies a large space. Summary of the invention

Each knife set 22 includes a first rotating shaft 221 , a blade 222 and a limiting block 223 . The first rotating shafts 221 of the two knife groups 22 are arranged side by side and extend in the front-to-back direction, and the front and rear ends of each first rotating shaft 221 are rotatably connected to the front and rear side walls of the first knife holder 21 respectively; the number of blades 222 is at least two, and they are arranged at intervals along the axial direction of the first rotating shaft 221, and the plane where each blade 222 is located is perpendicular to the axis of the first rotating shaft 221, and a gap 2220 is formed between two adjacent blades 222 of the same knife group 22, and the blades 222 of the two knife groups 22 are arranged in an alternating manner, and the corresponding blades 222 in the two knife groups 22 are tightly attached to each other; the limit blocks 223 are annular and sleeved on the first rotating shaft 221, corresponding to the above-mentioned gaps 2220 one by one, and each limit block 223 is located in the corresponding gap 2220 and abuts against the opposite surface of the adjacent blades 222.

The first knife seat 611 is connected to the surface of the feed side of the knife disc 5, and the outer side surface of the first knife seat 611 is respectively provided with a first mounting groove 6111 and a second mounting groove 6112 along both sides of the circumference of the knife disc 5; the tail of the third blade 612 of the first tool 6a is installed in the first mounting groove 6111, and the tail of the third blade 612 of the second tool 6b is installed in the second mounting groove 6112, and the head of the third blade 612 has a first blade edge 6121.

[0098] The second cutting member 62 includes a second knife seat 621 and a fourth blade 622. The second knife seat 621 of the first knife 6a and the second knife 6b is an integral piece. The second knife seat 621 is connected to the surface of the discharge side of the knife disc 5, and has a boss portion 6211 extending into the corresponding mounting port 51. The end surface of the boss portion 6211 and the first blade 6121 form the entrance of the second material guide channel 60, and the end surface of the boss portion 6211 is flush with the surface of the feed side of the knife disc 5, which can avoid blocking the cut food from entering the second material guide channel 60 on the one hand, and avoid the food entering the second material guide channel 60 from accumulating on the end surface of the boss portion 6211 on the other hand; the fourth blade 622 is installed on the end surface of the boss portion 6211 of the second knife seat 621, and the number of the fourth blade 622 is at least two, and they are arranged at intervals along the extension direction of the first blade 6121, and each fourth blade 622 has a second blade 6221 at one end facing the feed side of the knife disc 5.

[0099] The distance between the first blade 6121 of the first tool 6a and the knife disc 5 is recorded as D1, the distance between the first blade 6121 of the second tool 6b and the knife disc 5 is recorded as D2, the spacing between two adjacent fourth blades 622 of the first tool 6a is H1, and the spacing between two adjacent fourth blades 622 of the second tool 6b is H2, D1<D2, H1<H2, so that when the knife disc 5 rotates forward and reverse, sheet food of different thicknesses can be cut by the corresponding first blade 6121, and filamentary food of different sizes can be cut by the corresponding first blade 6121 and the second blade 6221. In addition, an inclined transition surface 6113 is provided on the outer surface of the first knife seat 611, and the transition surface 6113 is smoothly connected with the outer side surfaces of the third blades 612 of the first tool 6a and the second tool 6b along both sides of the circumference of the knife disc 5, thereby avoiding the knife 6 and the food from getting stuck.

[0100] In this embodiment, the third blades 612 of the first tool 6a and the second tool 6b are of the same size, the distances between the bottom surfaces of the first mounting groove 6111 and the second mounting groove 6112 and the cutter disc 5 are different, and the bottom surface of the first mounting groove 6111 is closer to the cutter disc 5, resulting in different values ​​of D1 and D2, and D1<D2. The advantage of this design is that the third blade 612 can be used as a universal part, and when the slice thickness needs to be adjusted, it is only necessary to replace the first tool holder 611 with a different mounting groove size.

[0101] In this embodiment, each fourth blade 622 is detachably mounted on the second blade holder 621 , and the distance between two adjacent fourth blades 622 can be adjusted by reducing or increasing the density of the fourth blades 622 .

[0102] In this embodiment, the first blade 6121 of the third blade 612 is in an outwardly convex arc shape. This arc design allows the cutting action of the food at any time to first cut the position close to the center axis and then cut the position gradually away, thereby making it easier to cut the food and convenient to bite into the food. The required motor torque is lower and the cutting is smoother and more stable.

[0103] In this embodiment, the vertical plane where the second rotating shaft 4 is located divides the knife disc 5 into a first zone and a second zone, and the discharge ends of the two first hoppers 32 are respectively facing the middle of the first zone and the middle of the second zone of the knife disc 5 of the first cutting component, and the discharge ends of the two second hoppers 33 are respectively facing the middle of the first zone and the middle of the second zone of the knife disc 5 of the second cutting component, so as to ensure that the cutting direction of the food cutting component 10 and the direction of gravity coincide as much as possible, so that there is no need to hold the food with hands when cutting.

[0104] One point on the second blade 2221 of the second blade 222 is marked as point O, and the straight line extending along the radial direction of the blade disc 1 and passing through point O is marked as straight line m. The corresponding second blade 222 is substantially perpendicular to straight line m, that is, the second blade 222 is substantially perpendicular to the blade disc 1, and when point O moves to the horizontal plane where the rotating shaft 4 is located, the corresponding second blade 222 is substantially arranged vertically. In this way, when any second blade 222 rotates with the blade disc 1 to the horizontal plane where the rotating shaft 4 is located, the cutting force applied to the food is in the vertical downward direction, which coincides with the direction of gravity of the food. In this state, the state of the food is the most stable, and under the limitation of the current food flow channel, the effect of not needing hand support and not spinning the food can be achieved.

[0105] In this embodiment, the difference between the first cutting component and the second cutting component is that the second cutting component is provided with a fourth blade 622, so it can be used in conjunction with the third blade 612 to cut food into filaments, while the first cutting component is not provided with the fourth blade 622, so the single third blade 612 can only cut food into slices.

[0106] The driving mechanism 7 is arranged in the base 11, and includes a first gear 71, a second gear 72, a third gear 73, a fourth gear 74, a fifth gear 75, a sixth gear 76, a seventh gear 77 and a driving member 78. Specifically, the driving member 78 is a motor having a power output shaft arranged substantially vertically; there are two first gears 71, which correspond to the first rotating shafts 221 one by one, each first gear 71 is coaxially mounted at the rear end of the corresponding first rotating shaft 221, and the two first gears 71 are meshed with each other; the second gear 72 is coaxially mounted on the rear side of one of the first gears 71; the third gear 73 is coaxially mounted on the front end of the second rotating shaft 4, meshing with the second gear 72; the fourth gear 74 is coaxially mounted on the rear end of the second rotating shaft 4; the fifth gear 75 is rotatably connected to the second tool holder 3, meshing with the fourth gear 74; the sixth gear 76 is a bevel gear, coaxially mounted on the front side of the fifth gear 75; the seventh gear 77 is a bevel gear, coaxially mounted on the top end of the power output shaft of the driving member 78, meshing with the sixth gear 76. The fourth gear 74, the fifth gear 75, the sixth gear 76 and the seventh gear 77 constitute a first speed change gear set, which transmits the power of the driving member 78 to the second rotating shaft 4. The first gear 71, the second gear 72 and the third gear 73 constitute a first speed change gear set, which transmits the power of the second rotating shaft 4 to the first rotating shaft 221. In this way, on the basis of sharing the same driving member 78, the requirements of low speed and high torque of the meat cutting module 2 and high speed and low torque of the vegetable cutting module 10 can still be met.

[0107] The receiving box 8 is arranged at the bottom of the inner cavity of the base 11, and can be pulled forward and backward from the clearance opening 111 to enter and exit the housing 1. The receiving box 8 has a first receiving groove 81 and a second receiving groove 82 with top openings. The top opening of the first receiving groove 81 faces the first discharge opening 213 of the first tool holder 21, and the top opening of the second receiving groove 82 faces the second discharge opening 312 of the second tool holder 3.

[0108] The working principle of this embodiment is as follows:

[0109] (1) Meat cutting mode: The driving member 78 is started to drive the seventh gear 77 to rotate, the sixth gear 76 rotates accordingly and drives the fifth gear 75 to rotate synchronously, the fourth gear 74 rotates accordingly, and then drives the third gear 73 to rotate through the second rotating shaft 4, the second gear 72 rotates accordingly and drives the first gear 71 to rotate synchronously, and then drives the blade 222 to rotate through the first rotating shaft 221;

[0110] ① When the user needs to cut thicker slices of meat, the meat can be put into the first feeding port 121 located in the front, and the meat falls under the action of gravity. The first blades 222a that rotate relatively cooperate with each other and cut the meat into slices. Under the stopping action of the first rack 232a, the meat slices in the gap 2220 are gradually separated from the first blade 222a and fall into the first receiving slot 81 of the receiving box 8 through the first discharge port 213. The thickness of the cut meat slices is substantially the same as W1.

[0111] ② When the user needs to cut thinner meat slices, the meat block can be put into the first feeding port 121 at the rear, and the meat block falls under the action of gravity. The second blades 222b rotating relatively cooperate with each other and cut the meat block into meat slices. Under the stopping action of the second rack 232b, the meat slices in the gap 2220 are gradually separated from the second blade 222b and fall into the first receiving slot 81 of the receiving box 8 through the first discharge port 213. The thickness of the cut meat slices is substantially the same as W2.

[0112] (2) Vegetable cutting mode: The driving member 78 is started to drive the seventh gear 77 to rotate, and the sixth gear 76 rotates accordingly and drives the fifth gear 75 to rotate synchronously, and the fourth gear 74 rotates accordingly, and then the two groups of cutting components are driven to rotate synchronously around the axis of the second rotating shaft 4 through the second rotating shaft 4;

[0113] ① When it is necessary to cut into thin slices, the second rotating shaft 4 can be driven to rotate forward, and the food is put into the second feeding port 122 located on the right side and enters the corresponding first hopper 32. The food falls under the action of gravity until it contacts the knife disc 5 of the first cutting assembly, and is cut into slices by the first knife blade 6121 of the first rotating knife 6a (since the value of D1 is small, the obtained slice food is a thin slice). The cut slice food enters the containing box 31 through the second material guide channel 60 of the first knife 6a, and finally falls into the second receiving slot 82 of the receiving box 8 through the second discharge port 311;

[0114] ② When thick slices need to be cut, the second rotating shaft 4 can be driven to reverse, and the food is put into the second feeding port 122 on the left side and enters the corresponding first hopper 32. The food falls under the action of gravity until it contacts the knife disc 5 of the first cutting assembly. The reversed second cutter 6b cuts the food into slices through the first blade 6121 (due to the large value of D2, the obtained slice food is thick slices). The cut slice food enters the containing box 31 through the second material guide channel 60 of the second cutter 6b, and finally falls into the second receiving slot 82 of the receiving box 8 through the second discharge port 311;

[0115] ③ When thick filaments need to be cut, the second rotating shaft 4 can be driven to rotate forward, and the food is put into the third feeding port 123 on the right side and enters the corresponding second hopper 33. The food falls under the action of gravity until it contacts the knife disc 5 of the second cutting assembly. The second knife 6b that rotates forward cooperates with the first blade 6121 and the second blade 6221 to cut the food into filaments (due to the large values ​​of D2 and H2, the obtained filaments are thick filaments). The cut filaments enter the containing box 31 through the second material guide channel 60 of the second knife 6b, and finally fall into the second receiving slot 82 of the receiving box 8 through the second discharge port 311;

[0116] ④ When it is necessary to cut into filaments, the second rotating shaft 4 can be driven to reverse, and the food can be put into the third feeding port 123 on the left and enter the corresponding second hopper 33. The food falls under the action of gravity until it contacts the knife disc 5 of the second cutting assembly. The reversed first tool 6a is cut into filaments by the first blade 6121 and the second blade 6221 (since the values ​​of D1 and H1 are small, the obtained filamentous food is filaments). The cut filamentous food enters the containing box 31 through the second material guide channel 60 of the first tool 6a, and finally falls into the second material receiving trough 82 of the receiving box 8 through the second discharge port 311.
