Furthermore, said stationary blade holder has a first blade component, said rotating blade holder has second blade components arranged at acute angles to the plane of rotation, and the opening direction of the acute angles corresponds to the direction of rotation.When food is fed into the cutting cylinder from above, the large angled surface of the second blade component exerts pressure on the food during the cutting process, pushing it into the first blade component. This first blade component then cuts the food into a specific shape, such as cubes or strips. This design allows for a smaller size of the accessory, making it lightweight and space-saving. Furthermore, it enables the cutting of larger food items with less risk of hand injuries, thus improving the user experience.

[0019] Furthermore, the said fixed blade holder has a mounting opening, the said first blade component is inserted into the said mounting opening, and the outer surface of the said first blade component is flush with the outer surface of the fixed blade holder.

[0020] The above description indicates that the outer surface of said first blade component is flush with the outer surface of the stationary blade holder, allowing the food to come into contact with the first blade component quickly, thereby increasing cutting efficiency.

[0021] Furthermore, the aforementioned first blade component consists of several crosswise arranged transverse and longitudinal blades, and the cutting edges of said blades are all located on one side of the outer surface of the stationary blade holder.

[0022] The above description shows that several shapes, such as cubes or strips, can be achieved by combining several crosswise arranged transverse and longitudinal blades.

[0023] Furthermore, all blades are detachably connected to each other.

[0024] The above description indicates that all blades are connected to each other in a detachable manner, which increases flexibility.

[0025] Furthermore, the cutting edges of the blades in the aforementioned second blade components are placed on the side of the free end of the corresponding acute angle.

[0026] Furthermore, the plane in which the blade lies in the aforementioned second blade components is arranged tangentially to the aforementioned plane of rotation.

[0027] Furthermore, the number of said second blade components is more than two, and these are evenly distributed on the plane of rotation of the rotating blade holder.

[0028] The above description shows that the aforementioned design can improve cutting efficiency.

[0029] This utility model also provides a cutting device comprising a device holder, a feed frame mounted above the device holder, a drive motor placed on one side of the device holder, an outlet frame mounted on the other side of the device holder, and said cutting cylinder; wherein said feed frame has a feed opening, said outlet frame has an outlet opening; said stationary blade holder is fixedly connected to the outlet frame, and the output shaft of said drive motor is fixedly connected to the rotating blade holder.

[0030] The foregoing description shows that this utility model has the following positive effect: If the aforementioned cutting cylinder is used in a cutting device, a compact cutting product characterized by high safety is thus realized.

[0031] Furthermore, the said rotating blade holder has cylindrical locking grooves on the side corresponding to the position of the output shaft of the drive motor and facing the outlet opening, and the said stationary blade holder has locking pins inserted into the said locking grooves and matching the said locking grooves at the positions corresponding to the said locking grooves.

[0032] The above description shows that the aforementioned design, the interplay of locking grooves and locking pins, prevents the problem of shifting or loosening, thus ensuring the stability of the structure.

[0033] Furthermore, the said first blade component is placed above the outlet frame and at the position corresponding to the feed opening of the feed frame, with the underside of said outlet frame being arranged at an angle.

[0034] The above description shows that, thanks to the aforementioned design, the food, after being cut by the first blade component, falls into the discharge rack and slides out easily due to the sloping surface of the underside.

[0035] Please see the Fig. 1 to 6, embodiment 1 of this utility model reads as follows: This utility model provides a cutting device comprising a device holder 1, a feed frame 2 mounted above the device holder, a drive motor positioned on one side of the device holder, an outlet frame 3 mounted on the other side of the device holder, and said cutting cylinder 4; wherein said feed frame 2 has a feed opening 21, and said outlet frame 3 has an outlet opening 31. The feed frame is a vertically arranged, column-shaped housing. A currently available product may be used for the drive motor, which should be positioned horizontally so that its output shaft is in a horizontal position.

[0036] The rotating blade holder has cylindrical locking grooves on the side corresponding to the position of the drive motor's output shaft and facing the outlet opening. The stationary blade holder has locking pins inserted into these locking grooves at the corresponding positions. A gap remains between the locking grooves and the locking pins, serving not only for assembly purposes but also providing the necessary clearance for their relative movement. During assembly, the locking pins are inserted into the locking grooves, allowing them to interact and ensuring that the stationary blade holder is stable both longitudinally and circumferentially, preventing any movement or loosening, thus guaranteeing the stability of the assembly.

[0037] The aforementioned cutting cylinder 4 comprises an annular stationary blade holder 41 and an annular rotating blade holder 42 rotatably placed over the said stationary blade holder, the said stationary blade holder is fixedly connected to the outlet frame and the output shaft of the said drive motor is fixedly connected to the rotating blade holder.

[0038] The rotating blade holder is arranged coaxially with the stationary blade holder, and the axis on which it is located serves as the axis of rotation. A gap exists between the stationary blade holder and the rotating blade holder. The stationary blade holder 41 has a first blade component 411, specifically a mounting opening. The first blade component 411 is inserted into this mounting opening, and the outer surface of the first blade component 411 is flush with the outer surface of the stationary blade holder 41. This allows the food to come into contact with the first blade component quickly, thereby increasing cutting efficiency. Simultaneously, this prevents the second blade component from becoming entangled with the first blade component when the rotating blade holder is turned.The first blade component is positioned above the discharge rack and at the location corresponding to the feed opening of the feed rack, with the underside of the discharge rack being angled. After being cut by the first blade component, the food falls into the discharge rack and slides out easily due to the angled surface of the underside.

[0039] In this embodiment, the aforementioned first blade component 411 comprises several crosswise arranged transverse and longitudinal blades, and the cutting edges of these blades are all located on one side of the outer surface of the stationary blade holder, allowing for the creation of various shapes, such as cubes or strips. All blades are detachably connected to one another, which increases flexibility. Of course, they can also be permanently connected to one another to ensure the stability of the assembly.

[0040] The rotating blade holder 42 has second blade components 421 arranged at acute angles to the plane of rotation, and the opening direction of these acute angles corresponds to the direction of rotation. The cutting edges of the blades in these second blade components are positioned on the side of the free end of the respective acute angle. The plane in which the blade lies in these second blade components is tangential to the plane of rotation.

[0041] The number of the aforementioned second blade components 421 is greater than two, and they are evenly distributed on the plane of rotation of the rotating blade holder, whereby the aforementioned design improves cutting efficiency. Specifically, the two second blade components are distributed symmetrically on the rotating blade holder with the axis of rotation as its axis of symmetry.

[0042] In summary, the cutting cylinder provided by this utility model, comprising an annular stationary blade holder and an annular rotating blade holder rotatably fitted over said stationary blade holder, forming a cylindrical cutting tool assembly, significantly reduces the space wasted during operation of the device compared to the current state of the art. Furthermore, said stationary blade holder has a first blade component, said rotating blade holder has second blade components arranged at acute angles to the plane of rotation, and the opening direction of the acute angles corresponds to the direction of rotation.When food is fed into the cutting cylinder from above, the large, angled surface of the second blade component exerts pressure on the food during the cutting process, pushing it into the first blade component. This first blade component then cuts the food into a specific shape, such as cubes or strips. This design allows for a smaller, more compact accessory, making it lightweight and space-saving. Furthermore, it enables the cutting of larger food items with less risk of hand injuries, thus improving the user experience. When this cutting cylinder is used in a cutting device, it results in a compact and highly safe cutting product.

[0043] The foregoing is merely an embodiment of this utility model and in no way limits the scope of protection afforded by this utility model.
