Description

Technical Field

[0001] The present invention relates to the technical field of food processing machines, and in particular to a dicing mechanism for a fruit and vegetable dicing machine and a fruit and vegetable dicing machine. Background Art

[0002] The fruit and vegetable dicing machine is used to cut fruit and vegetable ingredients into dices or blocks. Generally speaking, the processing steps of dicing fruit and vegetable ingredients are generally to cut the ingredients into slices first, then cut the slices into strips, and finally cut the strips into dices.

[0003] For example, the Chinese utility model patent application with application number CN201821944001.1 (authorization announcement number: CN209063156U) discloses a food dicing device, comprising a shell having a rectangular cavity, wherein a slicing knife group consisting of a plurality of horizontally arranged long slicing blades arranged side by side up and down is provided in the shell, and the slicing knife group divides the rectangular cavity into two small rectangular cavities; the cavity to which the slicing blade edges face is the slicing cavity, and the other is the dicing cavity; the gaps between adjacent slicing blades and between the outermost slicing blade and the inner wall of the shell constitute slicing discharge ports, which connect the slicing cavity and the dicing cavity, and all slicing discharge ports are of uniform size. A dicing knife group consisting of a plurality of dicing blades intersecting vertically and horizontally is provided on the lower bottom surface of the dicing cavity. After slicing the food in the slicing cavity, the food enters the dicing cavity to complete the dicing of the food. When performing the cutting operation, put the food into the feed port, push the slicing push rod, so that the slicing push block of the slicing push body enters the slicing knife group to cut the food into slices, and then smoothly enters the dicing chamber, press the dicing push rod downward, so that the dicing push block of the dicing push body enters the dicing knife group to cut the sliced ​​food into dices, and then smoothly pushes it out from the discharge port below.

[0004] The dicing device in the above patent application cuts the food into multiple stacked sheet-like food ingredients at one time through the slicing knife group, and then pushes the dicing pusher to cut the multiple stacked sheet-like food ingredients into diced food ingredients at one time through the dicing knife group. Since multiple layers of sheet food ingredients are diced at one time, the cutting process has a large resistance, requires a large force, and the pressure on the food ingredients is relatively long, which can easily cause the food ingredients to be severely squeezed and damaged (for example, the part of the food ingredients that contacts the dicing cone will be crushed), affecting the cutting effect of the food ingredients; on the other hand, if the dicing knife group itself is not strong enough, it is also easy to deform, affecting its cutting effect. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a dicing mechanism for a fruit and vegetable dicing machine in response to the current status of the existing technology, which has a smooth cutting process and is not likely to cause damage to the food due to excessive pressure.

[0006] The second technical problem to be solved by the present invention is to provide a fruit and vegetable dicing machine using the above-mentioned dicing mechanism in response to the current status of the existing technology.

[0007] The technical solution adopted by the present invention to solve the first technical problem is: a dicing mechanism for a fruit and vegetable dicing machine, comprising a dicing tool assembly for dicing food materials,

[0008] The dicing tool assembly comprises:

[0009] A knife drum capable of rotating about its own axis, the knife drum as a whole being a grid-like structure with distributed dicing meshes, and a dicing blade formed on the inner side of the knife drum for dicing;

[0010] A knife disc is provided at the end of the knife drum and is capable of rotating with the knife drum. The knife disc is provided with a slicing knife for slicing the food to be processed along its radial direction. The knife disc is formed with a slicing knife adjacent to the slicing knife to pass through the inside and outside of the knife disc so that the slicing food cut by the slicing knife can enter the knife drum.

[0011] The squeezing roller is arranged inside the knife drum in a manner that can rotate around its own axis. The extension direction of the squeezing roller is basically consistent with the extension direction of the knife drum. During the rotation of the knife drum, the outer peripheral wall of the squeezing roller can be squeezed and matched with the dicing blade of the knife drum to squeeze the sheet-like food that falls into the knife drum from the inside to the outside of the knife drum to form diced food.

[0012] In order to prevent the food entering the knife cylinder from flowing out from the port thereof and ensure the dicing effect, the axes of the knife cylinder and the squeezing roller are substantially extended horizontally.

[0013] In order to ensure the squeezing effect between the knife cylinder and the squeezing roller and avoid the problem of food residue in the dicing mesh of the knife cylinder, the outer peripheral wall of the squeezing roller is also distributed with protrusions protruding radially outward. During the rotation of the squeezing roller and the knife cylinder, each of the protrusions on the squeezing roller can be embedded in the corresponding dicing mesh on the knife cylinder.

[0014] In order to form a grid-like knife cylinder structure, the knife cylinder includes annular blades arranged in sequence along its axial direction and strip blades arranged in sequence along the circumference of the knife cylinder and extending along the axial direction of the knife cylinder. The strip blades and the annular blades are arranged in an interlaced manner, thereby forming a grid-like structure with dicing mesh holes as a whole.

[0015] In order to ensure the reliability and strength of the annular blade and the strip blade after assembly, the inner side of each annular blade has a first card groove opened in sequence along its circumference, and the outer side of each strip blade has a second card groove opened in sequence along its length. Each strip blade is embedded in the first card groove of each annular blade in the same straight line direction through the second card groove.

[0016] Generally speaking, the rotation of the knife drum and the rotation of the squeezing roller can be driven by two independent driving mechanisms respectively, and the rotation directions of the two can be the same or opposite. However, in order to reduce the number of driving mechanisms, simplify the structure of the dicing module, make it more compact and small, and ensure the extrusion and dicing effect of the two during the rotation process, a driving mechanism is also included, and the power output end of the driving mechanism is connected to the knife drum and one of the squeezing rollers through a transmission connection. The knife drum and the squeezing roller are also linked through a gear transmission assembly, so that the two can rotate synchronously in the same direction.

[0017] In order to simplify the structure of the gear transmission assembly and realize the synchronous rotation of the squeezing roller and the knife cylinder, the gear transmission assembly includes:

[0018] A transmission gear is coaxially connected to the squeezing roller;

[0019] The transmission gear ring is arranged on one end of the knife cylinder away from the knife disc. The transmission gear ring has an external tooth portion for transmission connection with an external driving mechanism and an internal tooth portion for meshing with the transmission gear.

[0020] As an improvement, the driving mechanism includes a driving motor, an output shaft of the driving motor is provided with a driving gear, and the driving gear is in driving connection with the outer tooth portion of the transmission gear ring.

[0021] The technical solution adopted by the present invention to solve the second technical problem is: a fruit and vegetable dicing machine includes a machine body with a working chamber formed therein, and also includes the above-mentioned dicing mechanism, which is arranged in the working chamber of the machine body.

[0022] In order to ensure that the food can be smoothly brought to the position of the extrusion roller through the knife drum immediately after being cut into slices, so as to realize the dicing and extrusion operation, a feeding hopper is also provided on the machine body, and the outlet of the feeding hopper is opposite to the knife disc. The vertical plane passing through the axis of the knife drum is recorded as the first vertical plane. The outlet of the feeding hopper and the extrusion roller are respectively located on both sides of the first vertical plane, and the extrusion roller is arranged adjacent to the bottom of the knife drum.

[0023] To achieve automatic feeding of ingredients during the cutting process and prevent shaking or jumping of ingredients during the cutting process, the first vertical plane divides the rotating cutter disc into a first, downward-rotating cutter disc portion and a second, upward-rotating cutter disc portion. The outlet of the feeding hopper is opposite the first cutter disc portion. The outlet of the feeding hopper on the machine body is opposite the first, downward-rotating cutter disc portion. As a result, during the rotation of the cutter disc, the cutting direction of the cutter disc on the ingredients is in the same direction as the direction of gravity on the ingredients. Therefore, automatic feeding of ingredients can be achieved without the need for an additional extrusion component to apply pressure during the feeding process.

[0024] In order to install the tool assembly formed by assembling the cutter disc and the cutter cylinder onto the machine body, the middle portion of the cutter disc has an axially extending first connecting shaft, which is rotatably connected to the side wall of the working chamber.

[0025] In order to rotatably mount the extrusion roller on the machine body, the knife cylinder has a first port and a second port that are opposite to each other in the axial direction. The knife disc is connected to the first port of the knife cylinder and blocks the first port. The end of the extrusion roller is also connected to a second connecting shaft, which extends out of the second port of the knife cylinder and is rotatably connected to the side wall of the working chamber.

[0026] Compared with the prior art, the present invention has the following advantages: the dicing machine adopts a structural design in which a knife disc is provided at the end of a knife barrel for slicing, and then the knife barrel and an extrusion roller provided inside the knife barrel cooperate to perform dicing. During dicing, the food is first cut into slices by the slicing knife on the knife disc and enters the interior of the knife barrel. The sliced ​​food is squeezed from the inside to the outside by the extrusion roller as the knife barrel rotates, and then becomes diced food and discharged. The structure of this dicing module rationally utilizes the internal space of the knife barrel, which can serve as both a buffer area for the diced food and a place for the extrusion roller component. In particular, during the rotation of the knife barrel, the diced food is continuously cut out and falls between the knife barrel and the extrusion baffle, and can then be squeezed into diced food in a timely manner. This continuous slicing and dicing process makes it less likely for food to accumulate between the knife barrel and the extrusion roller, and the knife barrel is less likely to deform. The diced food will not be damaged by prolonged extrusion, thereby ensuring the overall dicing effect and improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figure 1-Figure 5 A dicing machine includes a body 10, a dicing tool assembly arranged in the body 10, and a driving mechanism.

[0035] The body 10 is in a cubic state as a whole, and a working chamber 11 is defined inside it. A feeding port 120 connected to the working chamber 11 is provided on the top of the body 10. The working chamber 11 of the body 10 includes a feeding hopper 12 that gradually bends and extends downward from the feeding port 120. The outlet 121 of the feeding hopper 12 is opposite to the blade disc 30 of the dicing tool assembly.

[0036] The bottom of the working chamber 11 of the machine body 10 is a food receiving area 13, located below the dicing tool assembly. A food receiving box 14 is placed in this area, and a mounting opening (not shown) is provided on the front side of the machine body 10, corresponding to the food receiving area 13. The food receiving box 14 is mounted on the bottom of the working chamber 11 and slides back and forth on rails. Users can push and pull the food receiving box 14 in and out of the food receiving area 13 through the mounting opening on the side of the machine body 10.

[0037] See also Figure 2 The dicing tool assembly includes a knife cylinder 20, a knife disc 30, an extrusion roller 40, and a gear transmission assembly for transmitting power between the knife cylinder 20 and the extrusion roller 40.

[0038] See also Figure 4 and Figure 5 The knife cylinder 20 generally has a grid-like structure with dicing meshes 200, and a dicing blade is formed on its inner sidewall. The knife cylinder 20 has two axially opposed ports, designated as a first port 201 and a second port 202. Specifically, the knife cylinder 20 includes a cutter head 23, an annular blade 22, and a strip blade 21. The cutter head 23 is annular and located at the second port 202 of the knife cylinder 20.

[0039] In order to form a grid-like structure of the knife drum 20, there are multiple annular blades 22, which are arranged in sequence along the axial direction of the knife drum 20. Correspondingly, there are also multiple strip blades 21, which are arranged in sequence along the circumference of the knife drum 20. Each strip blade 21 extends along the axial direction of the knife drum 20. One end of the strip blade 21 is inserted into the hob 23 for fixation, and the other end can be connected to the cutter disc 30 by bonding. In order to achieve the reliability and strength of the annular blades 22 and the strip blades 21 after assembly, the inner side of each annular blade 22 has a first card groove 220 opened in sequence along its circumference, and the outer side of each strip blade 21 has a second card groove 210 opened in sequence along its length. Each strip blade 21 is embedded in the first card groove 220 of each annular blade 22 located in the same straight line direction through each second card groove 210, thereby forming a knife net structure with a dicing mesh 200 as a whole. The inner sides of the strip blades 21 and the inner sides of the annular blades 22 are both provided with cutting edges. Thus, when the strip blades 21 and the annular blades 22 are assembled together, the cutting edges on the strip blades 21 and the annular blades 22 together constitute the dicing blades of the knife cylinder 20 .

[0040] The cutter disc 30 is a circular flat plate structure that is connected to the first port 201 of the cutter barrel 20. The cutter disc 30 has a first sidewall facing away from the interior of the cutter barrel 20 and a second sidewall facing the interior of the cutter barrel 20. The cutter disc 30 is provided with a sheet food inlet 310 that extends radially from the first sidewall to the second sidewall. The sheet food inlet 310 is provided with a slicing knife 31 for slicing food. The slicing knife 31 is strip-shaped and arranged along the extension direction of the sheet food inlet. The blade of the slicing knife 31 is exposed relative to the first sidewall of the cutter disc 30, so that the food stored in the feeding hopper 12 can be sliced ​​during the rotation of the cutter disc 30.

[0041] The aforementioned sheet food inlet 310 and the corresponding slicing knife 31 may also be provided in two or more portions and arranged at intervals in the circumferential direction of the knife disc 30 , thereby improving slicing efficiency.

[0042] The cutter head 30 has an axially extending first connecting shaft 32 in the middle thereof. An end of the first connecting shaft 32 is rotatably connected to a side wall of the working chamber 11 via a bearing.

[0043] The squeezing roller 40 is disposed within the blade cylinder 20, and its extension direction is substantially aligned with that of the blade cylinder 20. Specifically, in this embodiment, both the blade cylinder 20 and the squeezing roller 40 extend horizontally. An axially extending second connecting shaft 42 is connected to one end of the squeezing roller 40. A horizontally extending second connecting shaft 42 is also connected to the end of the squeezing roller 40. This second connecting shaft 42 extends beyond the second port 202 of the blade cylinder 20 and is rotatably connected to the sidewall of the working chamber 11 via a bearing. The first connecting shaft 32 connected to the cutter disc 30 and the second connecting shaft 42 connected to the squeezing roller 40 are arranged parallel to each other.

[0044] The gear transmission assembly includes a transmission gear 52 and a transmission ring gear 53. The transmission gear 52 is coaxially connected to the squeeze roller 40. Specifically, the transmission gear 52 is located adjacent to the second end 202 of the cutter cylinder 20. The transmission ring gear 53 is fixed to the cutter head 23 at the second end 202 of the cutter cylinder 20. The transmission ring gear 53 has an inner circumferential wall formed with an inner tooth portion 531 that meshes with the transmission gear 52. The transmission ring gear 53 also has an outer circumferential wall formed with an outer tooth portion 532 that provides a transmission connection to an external drive mechanism. Specifically, the working chamber 11 of the machine body 10 also houses a drive mechanism. The drive mechanism includes a drive motor 50. The output shaft of the drive motor 50 is provided with a driving gear 51 that meshes with the outer tooth portion 532 of the transmission ring gear 53. The output shaft of the drive motor 50 extends parallel to the first connecting shaft 32 and the second connecting shaft 42.

[0045] When the drive motor 50 is running, the drive gear 51 and the transmission ring gear 53 drive the knife drum 20 to rotate about its own axis. During the rotation of the knife drum 20, the internal teeth 531 of the transmission ring gear 53 and the transmission gear 52 on the squeezing roller 40 drive the squeezing roller 40 to rotate about its axis. As the squeezing roller 40 and the knife drum 20 rotate synchronously and in the same direction, the squeezing roller 40 and the dicing blade of the knife drum 20 squeeze and squeeze the flaked food into the knife drum 20 from the inside out, forming diced food.

[0046] See also Figure 3 The vertical plane passing through the axis of the knife cylinder 20 is recorded as the first vertical plane A, wherein the outlet of the feeding hopper 12 and the squeezing roller 40 are respectively located on both sides of the first vertical plane A. Figure 3As shown, the outlet of the feeding hopper 12 is located in the left half, and the squeezing roller 40 is located in the right half. Furthermore, the squeezing roller 40 of this embodiment is also disposed adjacent to the bottom of the knife barrel 20. Specifically, the first vertical plane A divides the rotating cutter disc 30 into a first cutter disc portion 30a that rotates downward (i.e., the direction of cutting the food is generally downward) and a second cutter disc portion 30b that rotates upward (i.e., the direction of cutting the food is generally upward). The outlet of the feeding hopper 12 is opposite the first cutter disc portion 30a of the cutter disc 30. During the rotation of the cutter disc 30, the direction of cutting the food by the cutter disc 30 is the same as the direction of gravity of the food. Therefore, automatic feeding of food can be achieved without the need for an additional squeezing component to apply pressure to the feeding process.

[0047] The above-mentioned structural design of "the outlet 121 of the feeding hopper 12 and the squeezing roller 40 are respectively located on both sides of the first vertical plane A" also enables the slicing process of the food and the dicing process of the sheet food to be completed in two areas far away from each other, wherein, after the food is cut into slices, it can be smoothly brought into the position of the squeezing roller 40 through the knife cylinder 20 to realize the dicing and extrusion operation, that is, the slicing action and the dicing action of the food can be carried out in sequence, avoiding the problem of food accumulation and ensuring the dicing effect.

[0048] The outer peripheral wall of the squeezing roller 40 of this embodiment can be a smooth wall structure. However, to ensure the squeezing effect between the blade cylinder 20 and the squeezing roller 40 and to prevent food residue in the dicing meshes 200 of the blade cylinder 20, a plurality of radially outwardly projecting protrusions 41 are preferably provided on the outer peripheral wall of the squeezing roller 40. Each protrusion 41 on the squeezing roller 40 corresponds to a respective dicing mesh 200 on the blade cylinder 20. During the synchronous rotation of the squeezing roller 40 and the blade cylinder 20, each protrusion 41 on the squeezing roller 40 can be embedded in the corresponding dicing mesh 200 of the blade cylinder 20. This effectively prevents food residue in the dicing mesh 200, particularly any residue from the last piece of sheet food.
