[0023] Example

[0024] Please refer to Figure 1-Figure 5 The utility model proposes an aluminum foil cutting tool, including an aluminum foil cutting tool, including a shell 1 connected to a cutting device, and a knife body 2 for cutting aluminum foil, wherein a wheel groove 11 is arranged on the shell 1, and pressure wheels 3 are installed on both sides of the wheel groove 11, and the wheel edge of the pressure wheel 3 protrudes out of the wheel groove 11, and there is a distance between the pressure wheels 3 on both sides, and the knife body 2 is slidably installed on the shell 1 and is located between the pressure wheels 3 on both sides. Preferably, the material of the pressing wheel 3 is plastic. When the pressing wheel 3 is pressed on the aluminum foil, if a soft material such as rubber is used, the pressing wheel 3 will be deformed, and the deformation distance may cause the blade body 2 to contact the aluminum foil, causing the aluminum foil to tear. The sliding of the blade body 2 can be controlled by the cutting device, that is, when cutting is required, the blade body 2 is driven to slide toward the aluminum foil for cutting. When cutting is not required, the blade body 2 is retracted to avoid the blade body 2 from contacting the aluminum foil. The pressing wheels 3 on both sides of the utility model can simulate the pressing effect on the aluminum foil. The pressing wheels 3 in the utility model have multiple groups, each group has two pressing wheels 3 and are located on both sides of the wheel groove 11. When working, along the cutting direction, one group of pressing wheels 3 will first contact the area to be cut, and the blade 2 will cut behind this group of pressing wheels 3. A second group of pressing wheels 3 is provided on both sides of the blade body 2 to avoid wrinkles of the aluminum foil during cutting. A group of pressing wheels 3 is provided behind the blade body 2 to avoid wrinkles of the aluminum foil after cutting to the front, causing irregular cutting.

[0025] In a specific embodiment, refer to Figure 2 , Figure 3 , Figure 4A slide groove 12 is provided in the housing 1, and the slide groove 12 is connected to the wheel groove 11. The blade 2 matches the slide groove 12 and is slidably installed in the slide groove 12. The top of the blade 2 is connected to the pressure handle 21 that passes through the housing 1. Preferably, the shape of the slide groove 12 is rectangular. The blade 2 is in contact with the aluminum foil by sliding. When cutting is required, the blade 2 extends out to contact the aluminum foil. When cutting is not required, the blade 2 slides and shrinks and separates from the aluminum foil. The cross section of the top view of the blade 2 cannot be circular. When it is circular, the blade 2 may rotate in the slide groove 12, causing the position of the blade 2 to be skewed, and the aluminum foil finally cut does not meet the standard, or causes the blade 2 to break, that is, the cross section of the top view of the blade 2 can be any shape, which is preferably rectangular.

[0026] In a specific embodiment, refer to Figure 2 , Figure 3 , Figure 4 , a spring groove 13 is arranged in the shell 1, the spring groove 13 is connected with the slide groove 12, the slide groove 12 is located between the wheel groove 11 and the spring groove 13, the diameter of the spring groove 13 is larger than the diameter of the slide groove 12, an elastic member 4 is installed in the spring groove 13, and one end of the elastic member 4 is in conflict with the shell 1, and the other end is in conflict with the limit member 5 installed on the pressing handle 21. In the present utility model, the driving mode of the knife body 2 is sliding, and the knife body 2 can be extended or shortened by a telescopic mechanism. As a preferred mode, in the present utility model, when the pressing handle 21 is pushed to make the knife body 2 contact the aluminum foil, and the elastic member 4 is charged, when the pressing handle 21 is no longer pushed, the elastic member 4 will release the elastic force and push the limit member 5 to slide in the direction away from the aluminum foil, and at this time, the pressing handle 21 will drive the knife body 2 to slide in the direction away from the aluminum foil to retract the knife.

[0027] In a specific embodiment, refer to Figure 2 , Figure 3 , Figure 4 The top of the housing 1 is provided with a groove 14, which is connected to the spring groove 13, and a sealing sheet 6 is installed on the groove 14, and the pressing handle 21 passes through the sealing sheet 6. The housing 1 is provided with the groove 14 so that one end of the spring groove 13 can be disassembled, which is convenient for installing the elastic member 4. The thickness of the sealing sheet 6 is less than the groove depth of the groove 14; at the same time, the depth of the groove 14 and the thickness of the sealing sheet 6 can avoid the top of the housing 1 having a bulge, which is inconvenient to install with the cutting device.

[0028] In a specific embodiment, refer to Figure 4 , Figure 5 The cutter body 2 includes a clamp 22 and a blade 23. The top of the clamp 22 is connected to the pressure handle 21. The clamp 22 is provided with a clamping groove 231 with an opening facing downward and clamping the blade 23. Screws are provided on both sides of the clamping groove 231 to fasten the blade 23. The setting of the clamp 22 can make the blade 23 on the tool replaceable, which is convenient for replacing the blade 23 when it is damaged.

[0029] In a specific embodiment, refer to Figure 2 When idle, the blade 23 has a blade edge higher than the bottom end of the pressing wheel 3, and when working, the blade edge 23 has a blade edge lower than the bottom end of the pressing wheel 3. When idle, the bottom end of the blade 23 needs to avoid contact with the aluminum foil, so the pressing wheel 3 needs to contact with the aluminum foil first to prevent misoperation and lead to aluminum foil cutting errors.

[0030] In a specific embodiment, refer to Figure 1 , flanges for installation are arranged on both sides of the housing 1. The flanges on both sides of the housing 1 are used to match the connection of the cutting device.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
