Description

A manually detachable food cutting knife set Technical Field

[0001] This invention relates to the field of kitchen equipment, and particularly to a manually detachable food cutting knife assembly. Background Technology

[0002] In the food processing industry, food cutting blade sets are crucial equipment for achieving efficient cutting. However, existing food cutting blade sets have many shortcomings. Most blade sets have complex structures that require specialized tools and involve cumbersome procedures, leading to inconvenience in cleaning and maintenance. Long-term use can also easily breed bacteria, affecting food safety. During cutting, some blade sets cause food to easily stick to the blades, hindering the cutting process and reducing work efficiency. In addition, the connection stability between the blade set and the power source is not good, and it is difficult to ensure uniform blade spacing, resulting in inconsistent cutting effects and failing to meet diverse cutting needs. Therefore, there is an urgent need for a food cutting blade set that is easy to assemble and disassemble, cuts smoothly, and has a stable connection. Summary of the Invention

[0003] This invention provides a manually detachable food cutting knife assembly. The technical problem it addresses is as follows: This solution solves the problems existing in current food cutting knife assemblies. Through the L-shaped slot connection between the protective plate and the support rod, the screw connection of the comb plate, and the use of plum nuts to secure the blades, it enables tool-free, quick manual assembly and disassembly, facilitating cleaning and maintenance and preventing bacterial growth. The hollow grooves of the comb plate, combined with the staggered blades, effectively block and remove food stuck to the blades, ensuring a smooth cutting process. The locking holes and limiting components of the connector improve the stability of the power connection, and the spacers ensure uniform blade spacing. This solves the problems of cumbersome assembly and disassembly, food sticking, unstable connection, and uneven cutting in existing technologies, meeting the needs for efficient and clean cutting.

[0004] To achieve the above-mentioned objectives, the present invention provides a manually detachable food cutting knife assembly, comprising a frame structure and a knife assembly structure. The knife assembly structure is located inside the frame structure. The frame structure includes two protective plates located on both sides of the knife assembly structure, and a support rod detachably connected between the two protective plates. The support rod is connected to the four corners of the protective plates. The knife assembly structure has two sets, including a first knife assembly and a second knife assembly. The first knife assembly includes a first rotating shaft and a first blade. Multiple first blades are provided and connected to the first rotating shaft at intervals. The second knife assembly includes a second rotating shaft and a second blade. Multiple second blades are provided and connected to the second rotating shaft at intervals. The first blades and the second blades are arranged alternately.

[0005] The frame structure is detachably equipped with two blade comb plates, which are located inside the frame structure at the lower part and between the first and second rotation axes, respectively. The blade comb plates are provided with long strip-shaped hollow grooves for the first and second blades to pass through. When the blades cut the food, if the food sticks to the blades, when the blades rotate to the blade comb plates, the blade comb plates will block the food and cause it to fall downwards.

[0006] Furthermore, each of the four corners of the protective plate is provided with a mounting slot, and the support rod is provided with a thin rod segment that engages with the mounting slot.

[0007] Furthermore, the mounting slot is an L-shaped slot, which includes an inlet section and a bending section. The thin rod segment of the support rod is pushed in from the inlet section and then pushed to the bending section, embedding the thin rod segment into the bending section, making it less likely for the support rod to slip out of the mounting slot.

[0008] Furthermore, the first blade and the second blade are annular blades. The first blade is sleeved on the first rotating shaft, and the second blade is sleeved on the second rotating shaft. In order to ensure that the spacing between each blade is the same, annular spacers are sleeved on the first rotating shaft and the spacers are placed between each of the first blades. Spacers are sleeved on the second rotating shaft and the spacers are placed between each of the second blades.

[0009] The first and second rotating shafts each have a threaded head at one end, and the protective plate has a connection opening. Both ends of the first and second rotating shafts pass through the connection opening, and the threaded heads of the first and second rotating shafts are connected to a plum nut. A washer is placed between the plum nut and the protective plate. After the plum nut is tightened, the first blade and the bushing are secured to the first rotating shaft, and the second blade and the bushing are secured to the second rotating shaft. The other end of the first and second rotating shafts each has a connector for connecting to a power source.

[0010] Furthermore, the connector head is provided with a locking hole for connecting the drive shaft of the power source.

[0011] Furthermore, a limiting member is provided on the outside of the connector, the width of which is greater than the width of the connection opening, and a gasket is provided between the connector and the protective plate.

[0012] Furthermore, a spacer is provided between the first blade and the protective plate, and a spacer is provided between the second blade and the protective plate.

[0013] Furthermore, the bottom of the comb plate is provided with an overlapping plate, which extends on both sides. The width of the overlapping plate is greater than the width of the comb plate, and the overlapping plate is detachably connected by bottom screws and a protective plate.

[0014] The beneficial effects of this invention are as follows: The food cutting knife assembly of this invention can be manually disassembled and assembled. In its frame structure, the protective plate and support rod are connected by an L-shaped mounting slot, which allows for quick manual disassembly and assembly without tools, making it convenient and fast. The comb plate is detachably connected to the protective plate by bottom screws. In the knife assembly structure, the first blade and the second blade are fastened to the rotating shaft by a nut, washer, and spacer. During disassembly, simply unscrewing the nut allows for the removal of the blades and spacers one by one, enabling complete manual disassembly of the entire structure, which facilitates the cleaning and maintenance of each component. The two sets of staggered blades, together with the hollow grooves on the comb plate, can effectively block food adhering to the blades after cutting and cause it to fall downwards, ensuring a smooth cutting process. The connectors at one end of the first and second rotating shafts are equipped with locking holes and limiting components, which facilitates connection to the power source and ensures connection stability. At the same time, the spacer ensures that the spacing between each blade is the same, improving the uniformity of cutting. The overall structure is reasonably designed and combines practicality, convenience, and efficiency. Attached Figure Description
