Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a meat slicing knife assembly for a food processing machine and the food processing machine itself. Background Technology

[0002] Existing food processing machines, such as meat slicers, typically include a main unit and a processing chamber mounted on the main unit. The processing chamber has an installation port, and a meat slicer assembly is installed into the processing chamber through this port. The meat slicer assembly includes a mounting frame with a gearbox and rotary cutting blades. The mounting frame has a mounting groove with an opening at the top, which houses two sets of rotary cutting blades that are driven by the gearbox. Each set of rotary cutting blades includes a blade shaft and multiple spaced blades mounted on the blade shaft. When using the meat slicer, the user places the food into the processing chamber, and the motor drives the blades to rotate, thus slicing the meat. However, users have found that meat slices tend to stick to the blades during actual use. To solve this problem, Chinese Utility Model Patent CN201720663623.6 discloses a meat slicer with two blade combs on the blade holder. The comb teeth insert between adjacent blades, scraping off meat slices between the blades and effectively preventing meat slices from being caught or sticking to the blades during slicing. However, this type of comb uses two relatively thin rods to fix the comb teeth. When installing the comb, the user needs to install the two rods into the inclined groove of the bracket, which is a rather cumbersome installation process. Furthermore, when the user holds the relatively thin rod and presses it into the inclined groove towards the cutting blade, it is very easy to hit the blade, causing the user's fingers to be cut, which seriously affects the consumer's user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a meat cutting knife assembly for a food processing machine and a food processing machine. Under the premise that existing food processing machines, such as meat cutting machines, add a comb to avoid meat slices being clamped between the blades, how to solve the problem that the installation of the comb requires the separate installation of two small rods, which leads to low installation efficiency and easy contact with the blades.

[0004] To achieve the above objectives, this utility model provides a meat cutting knife assembly for a food processing machine. The meat cutting knife assembly includes a mounting bracket with a gearbox, a rotary cutting blade, and a blade comb. The mounting bracket has a mounting groove with an opening at the top. The mounting groove contains two sets of rotary cutting blades that are driven and connected to the gearbox. Each set of rotary cutting blades includes a blade shaft and multiple spaced blades mounted on the blade shaft. The rotary cutting blades and the blade comb are interlocked. The blade comb includes a rectangular support and two sets of comb teeth on opposite sides of the support. The two sides of the support without comb teeth form a gripping part that cooperates with the mounting bracket. The bottom of the gripping part is higher than the rotary cutting blade, and the gripping part is located on the axial outer side of the rotary cutting blade.

[0005] This application designs the blade comb as including a rectangular bracket and two sets of comb teeth on opposite sides of the bracket. This allows the blade comb to be installed onto the mounting frame in one go during installation. Compared to the existing method of installing the blade comb onto the mounting frame separately using two rods with comb teeth, this significantly improves installation efficiency, reduces operation steps, and makes the blade comb easier to spot, preventing loss. Simultaneously, the two rods of the bracket without comb teeth form a grip that mates with the mounting frame. The bottom of the grip is higher than the rotary cutter and located axially outside the rotary cutter. This allows the user to easily install the blade comb by holding the grip, improving ease of operation. Furthermore, compared to directly gripping smaller rods, when holding the grip, the fingers are away from the rotary cutter, effectively preventing accidental contact with the blade and ensuring operational safety, further enhancing the user experience.

[0006] In a preferred embodiment of a meat cutter assembly for a food processing machine, a mounting bracket and one of its grips are provided with a first limiting portion, and a gearbox and the other of its grips are provided with a second limiting portion, the first limiting portion and the second limiting portion being symmetrically arranged.

[0007] By providing a first limiting part to the mounting bracket and one of the grips, and a second limiting part to the gearbox and the other grip, the first and second limiting parts mutually restrict the blade comb when the user installs it onto the mounting bracket. This ensures the blade comb is securely positioned, prevents slippage, and further improves operational stability and safety. Furthermore, the symmetrical arrangement of the first and second limiting parts ensures correct installation of the blade comb regardless of its orientation, eliminating the need for user identification. This simplifies the operation, reduces the risk of misoperation, further optimizes the user experience, and ensures efficient and safe use every time.

[0008] In a preferred embodiment of a meat cutter assembly for a food processing machine, the mounting bracket has an upward-facing notch, one of the grips has a protrusion that mates with the notch, and the top surface of the gearbox has a boss, while the other grip has a groove that mates with the boss.

[0009] By providing an upward-facing notch on the mounting bracket, one of the grips has a protrusion that mates with the notch, and the top surface of the gearbox has a boss. The other grip has a groove that mates with the boss. This design allows users to identify the installation direction of the blade comb based on the positions of the protrusion and groove, ensuring correct installation and effectively preventing misinstallation. Simultaneously, it ensures precise engagement of the protrusion and notch, and the groove and boss during installation, providing double-limiting protection to prevent the blade comb from loosening during high-speed operation and ensuring its operational stability.

[0010] In a preferred embodiment of a meat cutter assembly for a food processing machine, the grip portion is provided with downwardly extending baffles, two baffles being inserted into the gaps between the rotary cutter and the mounting bracket and between the rotary cutter and the gearbox, respectively.

[0011] By providing downward-extending baffles on the grip, and inserting the two baffles into the gaps between the rotary cutter and the mounting bracket, as well as between the rotary cutter and the gearbox, the gaps are sealed, effectively preventing food residue from entering during food processing, keeping the interior clean, avoiding the occurrence of odors or even mold due to residual food inside, and ensuring that there are no foreign objects interfering during operation, thus extending the service life of the components.

[0012] In a preferred embodiment of a meat cutter assembly for a food processing machine, the baffle is provided with a vertically extending rib that abuts against the inner wall of a mounting bracket or gearbox.

[0013] By incorporating raised ribs into the baffle plate, a tight fit can be achieved between the baffle plate and the mounting bracket or gearbox during downward insertion. Compared to a thicker overall baffle plate, this significantly reduces the amount of material required for mold production, thereby lowering production costs. It also reduces the contact area between the baffle plate and the mounting bracket or gearbox, thus reducing friction and making the installation of the comb smoother, improving the user experience. Furthermore, the raised rib design enhances the baffle plate's resistance to deformation, ensuring structural stability during long-term use and extending its service life.

[0014] In a preferred implementation of a meat slicing blade assembly for a food processing machine, the axial width of the slit is greater than the distance between two adjacent blades.

[0015] By ensuring that the axial width of the gap is greater than the distance between two adjacent blades, the baffle can only be inserted into the gap during the insertion of the comb. When the baffle is inserted between the blades, it will be blocked due to the insufficient width of the gap, thus preventing the baffle from being mistakenly inserted into the gap between the blades, causing damage or safety hazards. This achieves the protection of the blades, ensures the sharpness of the blades, and ensures the smooth processing of food.

[0016] In a preferred implementation of a meat cutter assembly for a food processing machine, the bottom of the baffle is located between or above the cutter shafts of two sets of rotary cutters.

[0017] By positioning the bottom of the baffle between or above the cutter shafts of the two sets of rotary cutters, the baffle can smoothly insert downwards without interfering with the cutter shafts, ensuring that the baffle is stably fixed in the predetermined position. This further enhances the overall structural stability of the component and ensures the efficiency and safety of the processing.

[0018] In a preferred embodiment of a meat slicing knife assembly for a food processing machine, the comb teeth and the support are integrally formed.

[0019] By integrating the comb teeth and the bracket into a single unit, the step of installing and fixing the two is eliminated, which helps to improve production efficiency, while also reducing the failure rate caused by improper installation and ensuring the overall structural integrity of the component.

[0020] In a preferred embodiment of a meat cutter assembly for a food processing machine, the comb teeth are made of metal, the support is made of plastic, and the support and comb teeth are integrally molded with a rubber coating.

[0021] By using metal comb teeth and plastic support, the comb teeth are made of metal to ensure strong rigidity and to catch food, while the plastic support achieves a lightweight design, reducing the overall weight and making it easy to operate.

[0022] As a preferred embodiment of this application, this application also includes a food processing machine, including the meat slicing knife assembly, the main unit, and the processing cavity installed on the main unit as described above. The processing cavity is provided with an installation port, and the meat slicing knife assembly is installed in the processing cavity through the installation port.

[0023] By applying the above-mentioned meat slicing knife component to food processing machines, installation efficiency can be improved, accidental finger contact with the blade can be avoided, ensuring operational safety and enhancing the user experience. Attached Figure Description

[0033] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0034] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figures 1 to 6 As shown, this utility model provides a meat cutting knife assembly for a food processing machine. The meat cutting knife assembly includes a mounting frame 3 with a reduction gearbox 1, a rotary cutting blade 4, and a comb 2. The mounting frame 3 has a mounting groove with an open top. The mounting groove contains two sets of rotary cutting blades 4 that are connected to the reduction gearbox 1. Each set of rotary cutting blades 4 includes a blade shaft and multiple spaced blades mounted on the blade shaft. The rotary cutting blades 4 and the comb 2 are interlocked. The comb 2 includes a rectangular support 22 and two sets of comb teeth 23 on opposite sides of the support 22. The two sides of the support 22 without comb teeth 23 form a gripping part 21 that cooperates with the mounting frame 3. The bottom of the gripping part 21 is higher than the rotary cutting blade 4 and the gripping part 21 is located on the axial outer side of the rotary cutting blade 4.

[0036] This application configures the comb 2 as including a rectangular bracket 22 and two sets of comb teeth 23 on opposite sides of the bracket 22, so that the comb 2 can be installed onto the mounting frame 3 at the same time during installation. Compared with the existing method of installing the comb 2 onto the mounting frame 3 separately using two rods with comb teeth 23, this method can significantly improve installation efficiency, reduce operation steps, and make the comb 2 more visible to the user when storing it, thus avoiding loss of the comb 2. Meanwhile, the two rods of the bracket 22 without the comb teeth 23 are formed with a gripping part 21 that cooperates with the mounting bracket 3. The bottom of the gripping part 21 is higher than the rotary cutter 4, and the gripping part 21 is located on the outer side of the rotary cutter 4 in the axial direction. That is, the gripping part 21 is located at the outermost end of the rotary cutter 4 on both sides in the axial direction, so that when the user installs the comb 2, he / she can hold the gripping part 21 to install the comb 2, which improves the convenience of operation. Moreover, compared with directly holding the smaller rods for installation, when the fingers hold the gripping part 21, the fingers are away from the rotary cutter 4, which can effectively avoid the fingers accidentally touching the blade, ensure the safety of operation, and further improve the user experience.

[0037] It should be noted that this application does not specifically limit the structure of the mounting bracket 3, which can be any of the following embodiments:

[0038] Example 1: In this example, the mounting bracket 3 and one of the gripping parts 21 are provided with a first limiting part, and the gearbox 1 and the other gripping part 21 are provided with a second limiting part. The first limiting part and the second limiting part are symmetrically arranged.

[0039] By providing a first limiting part to the mounting bracket 3 and one of the gripping parts 21, and a second limiting part to the gearbox 1 and the other gripping part 21, the first and second limiting parts mutually limit each other when the user installs the comb 2 onto the mounting bracket 3. This ensures the comb 2 is securely positioned, prevents slippage, and further improves operational stability and safety. Simultaneously, the symmetrical arrangement of the first and second limiting parts ensures correct installation of the comb 2 regardless of its orientation, eliminating the need for the user to determine its direction. This simplifies the operation, reduces the risk of misoperation, further optimizes the user experience, and ensures efficient and safe operation every time.

[0040] Specifically, the first limiting part and the second limiting part can be two limiting protrusions respectively provided on the two gripping parts 21, and a limiting groove 213 provided on the mounting bracket 3 and the gearbox 1 to cooperate with the limiting protrusions. The limiting function of the comb 2 is achieved by the cooperation of the limiting protrusions and the limiting groove 213, and the limiting protrusions and the limiting groove 213 are symmetrically arranged.

[0041] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, in this embodiment, the mounting bracket 3 has an upward-facing notch 31, one of the gripping parts 21 has a protrusion 211 that mates with the notch 31, and the top surface of the gearbox 1 has a boss 11, while the other gripping part 21 has a groove 213 that mates with the boss 11.

[0042] By providing an upward-facing notch 31 to the mounting bracket 3, one of the gripping parts 21 having a protrusion 211 that mates with the notch 31, and a boss 11 on the top surface of the gearbox 1, and another gripping part 21 having a groove 213 that mates with the boss 11, the user can identify the installation direction of the comb 2 based on the positions of the protrusion 211 and the groove 213 when installing the comb 2, ensuring correct installation and effectively preventing misinstallation of the comb 2. Simultaneously, it ensures that the protrusion 211 and the notch 31, and the groove 213 and the boss 11, precisely fit during installation of the comb 2, achieving double limiting and preventing the comb 2 from loosening during high-speed operation, thus ensuring its operational stability. It should be noted that this application does not specifically limit the structure of the groove 213; preferably, as shown... Figure 3 As shown, the groove 213 is a fan shape that tapers from top to bottom, so that the groove 213 has a certain guiding effect on the boss 11, making it more convenient and faster for users to install.

[0043] As a preferred embodiment of this application, such as Figure 2 , Figure 4 As shown, the gripping part 21 is provided with downwardly extending baffles 212, and the two baffles 212 are respectively inserted into the gaps 5 between the rolling cutter 4 and the mounting bracket 3 and between the rolling cutter 4 and the gearbox 1.

[0044] By providing downwardly extending baffles 212 on the grip 21, and inserting the two baffles 212 into the gaps 5 between the rotary cutter 4 and the mounting bracket 3 and between the rotary cutter 4 and the gearbox 1 respectively, the gaps 5 are sealed, effectively preventing food residue from entering during food processing, keeping the interior clean, avoiding the situation where residual food inside causes odors or even mold, and ensuring that there are no foreign objects interfering during operation, thus extending the service life of the components.

[0045] Furthermore, the baffle 212 is provided with a vertically extending rib 2121, and the rib 2121 abuts against the inner wall of the mounting bracket 3 or the gearbox 1.

[0046] By providing vertically extending ribs 2121 to the baffle 212, the baffle 212 can achieve a tight fit with the mounting bracket 3 or gearbox 1 when inserted downwards. Compared to a thicker plate as a whole, this significantly reduces the amount of material used in the production of the baffle 212, thereby lowering production costs. It also reduces the contact area between the baffle 212 and the mounting bracket 3 or gearbox 1, thus reducing friction and making the installation of the comb 2 smoother, improving the user experience. Furthermore, the rib design enhances the baffle 212's resistance to deformation, ensuring structural stability during long-term use and extending its service life.

[0047] As a preferred embodiment, such as Figure 4 As shown, the width of the slit 5 along the axial direction is greater than the distance between two adjacent blades. Specifically, the width of the slit 5 along the axial direction is L1, and the distance between two adjacent blades is L2.

[0048] By making the axial width of the gap 5 greater than the distance between two adjacent blades, it is ensured that the baffle 212 can only be inserted into the gap 5 during the insertion process of the blade comb 2. When the baffle 212 is inserted between the blades, it will be blocked due to the insufficient width of the gap 5, thus preventing the baffle 212 from being mistakenly inserted into the gap between the blades, causing damage or safety hazards. This achieves the protection of the blades, ensures the sharpness of the blades, and ensures the smooth processing of food.

[0049] As a preferred embodiment, such as Figure 4 As shown, the bottom of the baffle 212 is located between or above the cutter shafts of the two sets of rolling cutters 4.

[0050] By positioning the bottom of the baffle 212 between or above the cutter shafts of the two sets of rotary cutters 4, the baffle 212 can smoothly insert downwards without interfering with the cutter shafts, ensuring that the baffle 212 is stably fixed in the predetermined position, further improving the overall structural stability of the component and ensuring the efficiency and safety of the processing.

[0051] It should be noted that this application does not specifically limit the relative relationship between the comb teeth 23 and the support 22. As a preferred embodiment of this application, such as Figure 2 As shown, the comb teeth 23 and the bracket 22 are integrally formed.

[0052] By making the comb teeth 23 and the bracket 22 as a single piece, the step of installing and fixing the two is eliminated, which helps to improve production efficiency, while also reducing the failure rate caused by improper installation and ensuring the overall structural integrity of the component.

[0053] It should be further noted that this application does not specifically limit the materials of the comb teeth 23 and the bracket 22. As a preferred embodiment, the comb teeth 23 are made of metal and the bracket 22 is made of plastic. The bracket 22 and the comb teeth 23 are integrally molded with adhesive.

[0054] By making the comb teeth 23 metal and the bracket 22 plastic, the comb teeth 23 can ensure strong rigidity to catch the food, while the bracket 22 plastic material achieves a lightweight design, reducing the overall weight and making it easy to operate.

[0055] As a preferred embodiment of this application, such as Figure 6 As shown, this application also includes a food processing machine, including the meat slicing knife assembly, the main unit 6, and the processing cavity 7 installed on the main unit 6 as described above. The processing cavity 7 is provided with an installation port, and the meat slicing knife assembly is installed in the processing cavity 7 through the installation port.

[0056] By applying the above-mentioned meat slicing knife component to food processing machines, installation efficiency can be improved, accidental finger contact with the blade can be avoided, ensuring operational safety and enhancing the user experience.

[0057] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
