Description

Technical Field

[0001] This utility model relates to the field of food preparation equipment technology, and in particular to a limiting structure for the blade barrel of a vegetable cutter. Background Technology

[0002] A salad machine is an automated electrical appliance that can cut vegetables and fruits to make salads. It has multiple interchangeable cutting modules that can handle common salad ingredients such as lettuce, tomatoes, cucumbers, and carrots. It typically supports shredding, slicing, dicing, and other cutting methods.

[0003] Existing salad machines require a cylindrical cutter barrel and cutter holder to cut ingredients. The cutter holder is embedded in a cutter holder slot on the side wall of the cutter barrel. The cutter barrel is coaxially mounted inside the discharge cylinder, and its bottom is rotated by the output shaft of the power unit. Each rotation of the cutter barrel slices or shreds the bottom contact area of ​​the ingredients. The slices or shreds are discharged outwards along the outer port of the rotating cutter barrel. To prevent the cutter barrel from dislodging during operation, it needs to be axially locked. However, in existing salad machines, the end of the power unit's output shaft has a cross-shaped locking head. After passing through a cross-shaped hole in the bottom plate of the cutter barrel, it rotates a certain angle and locks onto the inner side wall of the bottom plate of the cutter barrel, completing the axial locking, similar to the cutter barrel locking mechanism disclosed in the design patent CN308833701S. However, if the salad machine stops multiple times during operation, the blocked food can push the cutter barrel in the opposite direction, causing it to loosen and, in severe cases, the cutter barrel may fall off.

[0004] Therefore, it is necessary to develop a limiting structure for the blade barrel of a vegetable cutter to address the aforementioned defects. Utility Model Content

[0005] The purpose of this utility model is to provide a limiting structure for the blade of a vegetable cutter. By using a limiter to axially limit the blade of the vegetable cutter, the cutting process is ensured to be smooth and the blade of the vegetable cutter is less likely to fall off.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a limiting structure for a vegetable cutter's blade barrel, which is disposed between the material host housing of a salad machine and the vegetable cutter's blade barrel. The vegetable cutter's blade barrel is coaxially disposed within a discharge cylindrical cavity with its axis horizontal. It includes a limiter and a limiting ring. The limiting ring is coaxially disposed on the outer wall of the rear end of the vegetable cutter's blade barrel. The limiter is disposed on the outer wall of the material host housing and located directly above the discharge cylindrical cavity. The retractable working end of the limiter protruding downwards can abut against the rear shoulder of the limiting ring.

[0008] Furthermore, the limiter includes a limiter cover and a limiter core. The material host housing is integrally provided with a limiter bottom shell with top and bottom openings above the outer edge of the discharge cylinder cavity. The limiter cover is detachably fastened to the top opening of the limiter bottom shell and limits the limiter core within the locking slide cavity. The limiter core can slide up and down within the locking slide cavity. The locking tongue at the bottom end of the limiter core can abut against the rear shoulder of the limiter ring. The bottom end face of the locking tongue is an arc surface.

[0009] Furthermore, it also includes a compression spring. The back of the limiting core main board is vertically provided with a compression spring groove with a top opening. The bottom plate of the locking slide cavity is vertically provided with a central rib plate in the middle. The top of the central rib plate protrudes outward to form a stop beam. The compression spring is installed in the compression spring groove. The bottom end of the compression spring abuts against the bottom surface of the compression spring groove, and the top end of the compression spring abuts against the stop beam.

[0010] Furthermore, the front of the limiting core main board is provided with a guide hole protruding from the limiting device cover.

[0011] Furthermore, the outer edge of the bottom end face of the locking tongue is chamfered.

[0012] Furthermore, the blade barrel of the vegetable cutter has two symmetrically arranged blade holder slots, and a blade holder and / or a protective cover plate are installed in the blade holder slots.

[0013] Furthermore, the bottom end plate of the vegetable cutter is provided with a power interface for connecting the output shaft of the power unit; the power interface is specifically a regular hexagonal prism slot.

[0014] Compared with the prior art, the beneficial effects of the limiting structure of the blade barrel of the vegetable cutter of this utility model are as follows:

[0015] This utility model discloses a limiting structure for the blade barrel of a vegetable cutter. By adding a limiting device mounted on the outer wall of the main material housing, the downward-protruding working end of the limiting device abuts against the rear shoulder of the blocking limiting ring. This prevents the blade barrel from detaching outwards without affecting its rotation. This ensures a smooth cutting process and reduces the likelihood of the blade barrel falling off.

[0016] Furthermore, the limiter cover is detachably fastened to the top opening of the limiter's bottom shell, facilitating maintenance and replacement of the limiter core. Simultaneously, the locking tongue, inserted from top to bottom and abutting against the rear shoulder of the blocking limit ring, provides excellent anti-disengagement and reduces the occurrence of disengagement. The addition of the compression spring ensures the limiter core remains in a low position under normal conditions, reliably limiting the axial movement of the cutter's blade barrel. The central rib plate increases the structural strength against the reaction force of the compression spring, preventing bending and deformation of the limiter's bottom shell top plate due to prolonged pressure from the spring. The lever allows operators to manually pull the limiter core upwards, causing it to slide upwards along the locking cavity, disengaging the bottom end of the locking tongue from the rear shoulder of the limiter ring, thus disengaging the cutter's blade barrel for easy disassembly and removal. The addition of a chamfer on the outer edge of the locking tongue's bottom face allows the limiter ring to use this bevel to lift the locking tongue upwards when the cutter's blade barrel is installed into the discharge cylinder cavity, eliminating the need for an additional lever. By creating two blade holder slots on the blade barrel of the vegetable cutter, two blade holders can be installed, enabling two cuts to be completed in one rotation, thus improving cutting efficiency. In this application, the power interface uses a simplified hexagonal prism slot, requiring only power transmission without axial limiting, reducing the complexity of this part of the structure, increasing structural strength, and making it less prone to failure.

[0028] The core of this utility model is to provide a limiting structure for the blade barrel of a vegetable cutter. By using a limiter to axially limit the blade barrel of the vegetable cutter, the cutting process is smooth and the blade barrel is less likely to fall off.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Refer to the attached diagram. Figure 1 A three-dimensional structural diagram of a salad machine equipped with the limiting structure of the blade barrel of the vegetable cutter of this utility model; Figure 2 This is a three-dimensional structural diagram of the limiting structure of the blade barrel of the vegetable cutter of this utility model; Figure 3 for Figure 2 Front view sectional structural diagram; Figure 4 This is a schematic diagram of the three-dimensional structure of the vegetable cutter's blade barrel and blade holder assembled in this utility model; Figure 5 This is a three-dimensional structural diagram of the blade barrel of the vegetable cutter of this utility model; Figure 6 This is a cross-sectional view of the blade barrel of the vegetable cutter of this utility model; Figure 7 This is a three-dimensional structural diagram of the material handling unit housing in this utility model; Figure 8 This is a three-dimensional structural diagram of the limiter cover in this utility model; Figure 9 This is a schematic diagram of the three-dimensional structure of the limiting core in this utility model.

[0032] In one specific implementation, such as Figures 1-9 As shown, the limiting structure of the vegetable cutter barrel of this utility model is set between the material host housing 2 and the vegetable cutter barrel 1 of the salad machine. The material host housing 2 is detachably installed in the mounting slot of the power host 7. The vegetable cutter barrel 1 is coaxially set in the discharge cylindrical cavity 204 with the axis horizontal and can be driven to rotate by the output shaft of the power host 7. The limiting structure of the vegetable cutter barrel of this utility model includes a limiter and a limiting ring 103. The limiting ring 103 is coaxially set on the outer wall of the rear end of the vegetable cutter barrel 1 and is processed by injection molding. The limiter is set on the outer wall of the material host housing 2 and located directly above the discharge cylindrical cavity 204; the downward-protruding retractable working end of the limiter can abut against the rear shoulder of the limiting ring 103, and the two slide relative to each other.

[0033] By adding the limiter to the outer wall of the material host housing 2, and using the downward-protruding working end of the limiter to abut against the rear shoulder of the blocking limit ring 103, it is possible to prevent the cutter barrel 1 from coming off outward without affecting the rotation of the cutter barrel 1 itself. This ensures a smooth cutting process and reduces the likelihood of the cutter barrel falling off.

[0034] In one specific embodiment of this utility model, such as Figures 1-3 and Figures 7-9 As shown, the limiter includes a limiter cover 3 and a limiter core 4. The material handling unit housing 2 has a limiter bottom shell 201 with top and bottom openings integrally formed above the outer edge of the discharge cylindrical cavity 204, and its inner cavity is defined as a locking slide cavity. The limiter cover 3 is detachably fastened to the top opening of the limiter bottom shell 201 and confines the limiter core 4 within the locking slide cavity. The limiter core 4 can slide vertically within the locking slide cavity, and the locking tongue 402 at the bottom end of the limiter core 4 can abut against the rear shoulder of the blocking limit ring 103. The bottom surface of the locking tongue 402 is an arc surface.

[0035] Specifically, such as Figure 7 and Figure 9 As shown, the bottom opening of the locking slide cavity is not completely open. A baffle about half the height of the side wall is provided on the bottom wall. A baffle 401 is provided inwardly on the limiting core 4. The baffle 401 slides on the bottom plate of the locking slide cavity. The baffle can limit the bottom end face of the baffle 401 and prevent the limiting core 4 from falling out of the bottom opening.

[0036] Specifically, such as Figure 7 and Figure 8As shown, the limiter cover 3 has latches 302 on both sides, and the two inner walls of the locking slide cavity are respectively provided with inner slots 202. The latches 302 can be inserted into the inner slots 202 to fix the limiter cover 3.

[0037] The limiter cover 3 can be detachably fastened to the top opening of the limiter bottom shell 201, which facilitates the maintenance and replacement of the limiter core 4. At the same time, it is inserted from top to bottom and abuts against the locking tongue 402 on the rear shoulder of the blocking limit ring 103, which has good anti-disengagement performance and reduces the occurrence of disengagement.

[0038] Obviously, the limiter can also be locked using a cylindrical pin, which requires an annular groove to be provided on the outer wall of the rear end of the cutter barrel 1, and the pin head to be inserted into the annular groove for axial limiting. Similar simple replacement methods also fall within the protection scope of this utility model.

[0039] In one specific embodiment of this utility model, such as Figure 3 , Figure 7 and Figure 9 As shown, the limiter also includes a compression spring. A compression spring groove 404 with a top opening is vertically arranged on the back of the main plate of the limit core 4. A central rib plate 203 is vertically arranged in the middle of the bottom plate of the locking slide cavity, with the top of the central rib plate 203 protruding outwards to form a stop beam. The compression spring is installed in the compression spring groove 404, with its bottom end abutting against the bottom surface of the compression spring groove 404 and its top end abutting against the stop beam.

[0040] It should be noted that, in order to simplify the illustration of the main structural features, the compression spring is not shown in the patent illustration and should not be regarded as a limitation of this utility model.

[0041] By adding the compression spring, the limiting core 4 can be kept in a low position under normal conditions, which can reliably limit the axial movement of the cutter barrel 1. The central rib plate 203 increases the structural strength against the reaction force of the compression spring, preventing the top plate of the limiter bottom shell 201 from bending and deforming due to long-term pushing by the compression spring.

[0042] In one specific embodiment of this utility model, such as Figures 1-3 , Figure 8 and Figure 9 As shown, the front of the main board of the limiting core 4 has a guide hole 301 protruding from the limiting cover 3, and a lever 403 is provided. It is manufactured by injection molding.

[0043] The setting of the lever 403 makes it easy for the operator to manually pull the limiting core 4 upward, so that it slides upward along the locking cavity, and the bottom end of the locking tongue 402 disengages from the rear shoulder of the limiting ring 103, thus completing the disengagement of the vegetable cutter barrel 1, which is convenient for disassembly and removal.

[0044] Specifically, such as Figure 3 and Figure 9 As shown, the bottom end face of the locking tongue 402 is chamfered, and the top edge of the limiting ring 103 is rounded.

[0045] By adding a chamfer to the outer edge of the bottom face of the locking tongue 402, when the vegetable cutter tube 1 is installed into the discharge cylindrical cavity 204, the limiting ring 103 uses the inclined surface here to lift the locking tongue 402 upwards, without the need for additional pushing of the pusher plate 403.

[0046] In one specific embodiment of this utility model, such as Figures 1-6 As shown, the blade holder 1 of the vegetable cutter has two symmetrically arranged blade holder slots 101. A blade holder 5 and / or a protective cover are installed inside the blade holder slot 101. A groove is formed on the side wall of the blade holder slot 101 to engage with the side of the blade holder 5. The protective cover is used to seal the blade holder slot 101. A slicing blade or a shredding blade is installed on the blade holder 5. The limiting ring 103 is a complete circular ring, through which the latch 501 of the blade holder 5 passes and engages with the bottom edge of the limiting ring 103.

[0047] In existing vegetable cutter blade barrels 1, only one cutting blade holder 5 is installed, and it can only cut once per rotation. However, this application improves vegetable cutting efficiency by opening two cutting blade holder slots 101 on the vegetable cutter blade barrel 1, which can install two cutting blade holders 5, and can complete two cuts in one rotation.

[0048] In one specific embodiment of this utility model, such as Figures 3-6 As shown, a power interface 102 for connecting the output shaft of the power unit 6 is provided in the middle of the bottom end plate of the vegetable cutter barrel 1. The power interface 102 specifically adopts a regular hexagonal prism slot.

[0049] Obviously, the power interface 102 can also adopt a square hole slot or other regular prism hole slot, all of which can realize the transmission of power. Similar simple variations all fall within the protection scope of this utility model.

[0050] In this application, the power interface 102 adopts a simplified regular hexagonal prism hole slot, which only needs to transmit power and does not require axial limiting, thus reducing the complexity of this part of the structure, increasing the structural strength, and making it less prone to failure.

[0051] The usage process of the limiting structure of the vegetable cutter barrel of this utility model is as follows: During installation, the vegetable cutter barrel 1 is coaxially inserted into the discharge cylindrical cavity 204, ensuring that the power interface 102 faces inward and one end of the limiting ring 103 faces outward. During insertion, the inner shoulder of the limiting ring 103 pushes upward against the chamfered edge of the bottom end face of the locking tongue 402, causing the locking tongue 402 to rise. After the inner edge of the locking tongue 402 aligns with the rear shoulder of the limiting ring 103, it automatically falls down with a click, and the inner wall of the bottom end of the locking tongue 402 abuts against the rear shoulder of the limiting ring 103, completing the axial locking. Simultaneously, the power interface 102 on the back of the vegetable cutter barrel 1 is connected to the output shaft of the power unit 7. Turning on the salad machine allows food to be fed into the feeding port at the top of the main housing 2. The feeder pushes the food downwards, and each rotation of the cutter barrel 1 causes the cutting blade 5 at its cutting edge to cut off a piece of food, which then enters the inner cavity of the cutter barrel 1 and gradually flows out from the outer port into the receiving container. After cutting, the operator manually moves the lever 403 upwards, causing it to slide upwards along the locking cavity. The bottom end of the locking tongue 402 disengages from the rear shoulder of the limiting ring 103, disengaging the cutter barrel 1. The cutter barrel 1 can then be removed from the discharge cylinder cavity 204, and the cutting blade 5 can be easily disassembled for cleaning.

[0052] In summary, the limiting structure of the vegetable cutter barrel of this utility model, by adding a limiter set on the outer wall of the material host housing 2, and using the downward-protruding working end of the limiter to abut against the rear shoulder of the blocking limiting ring 103, can both prevent the vegetable cutter barrel 1 from detaching outward and not affect the rotation of the vegetable cutter barrel 1 itself. This ensures a smooth cutting process and reduces the likelihood of the vegetable cutter barrel falling off. In addition, the limiter cover 3 is detachably fastened to the top opening of the limiter bottom shell 201, facilitating the maintenance and replacement of the limiting core 4. At the same time, the locking tongue 402, inserted from top to bottom and abutting against the rear shoulder of the blocking limiting ring 103, provides good anti-detachment performance and reduces the occurrence of disengagement. By adding the compression spring, it can be ensured that the limiting core 4 is in a low position under normal conditions, which can reliably limit the axial movement of the vegetable cutter barrel 1. The central rib plate 203 increases the structural strength against the reaction force of the compression spring, preventing the top plate of the limiter bottom shell 201 from bending and deforming due to long-term pressure from the compression spring. The lever 403 allows operators to manually pull the limit core 4 upwards, causing it to slide upwards along the locking cavity, disengaging the bottom end of the locking tongue 402 from the rear shoulder of the limit ring 103, thus disengaging the cutter barrel 1 for easy disassembly and removal. By adding a chamfer to the outer edge of the bottom face of the locking tongue 402, when the cutter barrel 1 is installed into the discharge cylinder cavity 204, the limit ring 103 uses this chamfer to lift the locking tongue 402 upwards, eliminating the need for additional pushing of the lever 403. Two cutter holder slots 101 are provided on the cutter barrel 1, allowing for the installation of two cutter holders 5, enabling two cuts to be completed in one rotation, thus improving cutting efficiency. In this application, the power interface 102 adopts a simplified regular hexagonal prism hole slot, which only needs to transmit power and does not require axial limiting, thus reducing the complexity of this part of the structure, increasing the structural strength, and making it less prone to failure.
