In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, not as a limitation. Therefore, other examples of the exemplary embodiments may have different values, and it should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in the subsequent drawings. Example 1

[0040] This embodiment provides a novel knife roller, including a frame 1, characterized in that it also includes:

[0041] A rotating roller 2, wherein a knife seat 3 is fixedly sleeved on the rotating roller 2;

[0042] A semicircular blade 4, wherein the semicircular blade 4 is fixed on the blade holder 3, and the blade edge of the semicircular blade 4 protrudes from the outer periphery of the blade holder 3;

[0043] A knife sharpener 5, wherein the knife groove of the knife sharpener 5 matches the blade of the semicircular blade 4;

[0044] A movable component, used to drive the knife groove of the knife sharpener 5 to move toward the blade of the semicircular blade 4;

[0045] The knife sharpener 5 is movably arranged on the frame 1 through a movable assembly, and the roller 2 is fixedly rotatably arranged in the frame 1 .

[0046] In the present technical solution, since a sharpener 5 is movably arranged on the frame 1, after the blade of the semicircular blade 4 becomes blunt after long-term use, the sharpener 5 is driven by the movable component to move toward the semicircular blade 4. Since the aluminum foil cutting device is in operation, the roller 2 is in a rotating state, so that the roller 2 drives the knife holder 3 to rotate, and the knife holder 3 drives the semicircular blade 4 to rotate with the roller 2 as the axis (the present utility model is applied to the cutting of aluminum foil, and the working principle of the aluminum foil cutting device is the prior art, which will not be described in detail here);

[0047] After the sharpener 5 moves toward the blade of the semicircular blade 4 until the blade of the semicircular blade 4 conflicts with the blade groove of the sharpener 5, as the blade holder 3 drives the semicircular blade 4 to rotate with the roller 2 as the axis, all the blades of the semicircular blade 4 can pass through the blade groove of the sharpener 5 as the semicircular blade 4 rotates, so that the blade of the semicircular blade 4 moves and conflicts with the blade groove of the sharpener 5 to form a sharpening effect, thereby making the blade of the semicircular blade 4 sharper.

[0048] Through this structural design, by providing a sharpener 5, when the blade of the semicircular blade 4 becomes blunt due to long-term use, the blade of the semicircular blade 4 can be sharpened in cooperation with the sharpener 5 provided in the frame 1 as the roller 2 rotates without stopping the machine, so that the semicircular blade 4 can be sharpened in the working state, avoiding shutdown to affect production efficiency, and improving safety compared with manual sharpening by workers to avoid accidents. Example 2

[0049] This embodiment provides a new type of knife roller, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0050] Furthermore, the activity components include:

[0051] A movable groove 6, wherein the movable groove 6 is formed through the side wall of the frame 1;

[0052] A movable block 7, wherein the movable block 7 is movably arranged in the movable groove 6, and the rear end of the knife sharpener 5 is fixedly connected to the front end of the movable block 7;

[0053] A guide assembly, used to guide the movement of the movable block 7;

[0054] In the present technical solution, by providing a movable groove 6 and a movable block 7, it is convenient to move the sharpener 5 by manually pulling out the movable block 7. When sharpening is needed, the movable block 7 can be pulled to drive the sharpener 5 to move toward the semicircular blade 4. After the sharpening is completed, the movable block 7 can be pulled out to avoid excessive sharpening and reducing the service life of the blade.

[0055] Through this structural design, by providing the movable block 7 and the movable groove 6, it is convenient to pull the movable block 7 to drive the sharpener 5 to approach or move away from the semicircular blade 4, so that the knife can be sharpened at the appropriate time, avoiding the sharpener 5 always being in contact with the blade of the semicircular blade 4, thereby causing over-sharpening. Example 3

[0056] This embodiment provides a new type of knife roller, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0057] Furthermore, the guide assembly comprises:

[0058] Guide blocks 8, there are two guide blocks 8, and the two guide blocks 8 are fixedly arranged on both sides of the movable block 7;

[0059] A guide groove 9, wherein the frame 1 is provided with a guide groove 9 for the guide block 8 to move;

[0060] The guide groove 9 is connected to the movable groove 6 , and the guide block 8 is located in the guide groove 9 .

[0061] In the present technical solution, the guide block 8 and the guide groove 9 are provided to guide the movement of the movable block 7, so that the moving track of the movable block 7 is more stable and less prone to shaking, thereby stabilizing the moving track of the sharpener 5. Example 4

[0062] This embodiment provides a new type of knife roller, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0063] Furthermore, a compensation component is also included, and the compensation component includes:

[0064] A spring 10, wherein the spring 10 is located in the guide groove 9;

[0065] A threaded column 11, one end of which is fixedly connected to the rear end of the movable block 7, and the other end of which protrudes from the outer surface of the frame 1;

[0066] A driving nut 12, wherein the driving nut 12 is spirally arranged on the threaded column 11;

[0067] The end face of the driving nut 12 is disposed in contact with the outer side wall of the frame 1 , one end of the spring 10 is fixedly connected to the front end of the guide block 8 , and the other end of the spring 10 is fixedly connected to the frame 1 .

[0068] In the present technical solution, since a spring 10 is provided, one end of the spring 10 is fixedly connected to the front end of the guide block 8, and the other end of the spring 10 is fixedly connected to the frame 1, and the spring 10 is located in the guide groove 9, so that the guide block 8 has a force to move toward the semicircular blade 4 through the tension of the spring 10, so that the movable block 7 has a force to move toward the semicircular blade 4 through the guide block 8, so that the sharpener 5 has a force to move toward the semicircular blade 4 through the spring 10;

[0069] Since a threaded column 11 and a driving nut 12 are provided, one end of the threaded column 11 is fixedly connected to the rear end of the movable block 7, and the other end of the threaded column 11 protrudes from the outer surface of the frame 1, and the driving nut 12 is spirally arranged on the threaded column 11 and the end face of the driving nut 12 is arranged to contact with the outer side wall of the frame 1, so that when the movable block 7 moves toward the semicircular blade 4 through the pulling force of the spring 10, the threaded column 11 will be driven to move, and the threaded column 11 will drive the driving nut 12 to move. After the driving nut 12 moves to contact with the outer side wall of the frame 1, the movement of the movable block 7 will be restricted to prevent the movable block 7 from excessively moving due to the pulling force of the spring 10, thereby interfering with the semicircular blade;

[0070] It can be seen that the travel of the movable block 7 due to the tension of the spring 10 can be determined by adjusting the position of the drive nut 12 on the threaded column 11, and the movable block 7 can be controlled to move left and right by cooperating with the tension of the spring 10 by twisting the drive nut 12, so that the sharpener 5 can be driven to move closer to or away from the semicircular blade 4 by twisting the drive nut 12;

[0071] At the same time, it is also possible to avoid damage caused by the rigid contact between the semicircular blade and the sharpener 5. When the blade of the semicircular blade cuts into the blade groove of the sharpener 5, if the position of the sharpener 5 is too protruding, the blade of the semicircular blade can press the sharpener 5 back. At this time, the sharpener 5 will also have a force toward the semicircular blade through the tension of the spring 10, so that the sharpening effect is better.

[0072] With this structural design, by providing the spring 10, the drive nut 12 and the threaded column 11, the sharpener 5 can be driven to approach or move away from the semicircular blade 4 by twisting the drive nut 12. At the same time, it can also avoid the semicircular blade and the sharpener 5 from being damaged by rigid contact. If the position of the sharpener 5 is too prominent, the blade of the semicircular blade can press the sharpener 5 back. At this time, the sharpener 5 will also have a force toward the semicircular blade through the pulling force of the spring 10, so that the sharpening effect is better. Example 5

[0073] This embodiment provides a new type of knife roller, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0074] Furthermore, the planar portion of the semicircular blade 4 protrudes from both ends of the blade holder 3 and a transition piece 13 is formed along the circumference of the blade holder 3. The outer peripheral line of the transition piece 13 is involute shape, and the large end of the transition piece 13 is fixedly connected to the planar portion of the semicircular blade 4.

[0075] In the present technical solution, since a transition piece 13 is provided to achieve an arc transition effect between the blade holder 3 and the blade edge of the semicircular blade 4, the position of the sharpener 5 is too prominent. When the semicircular blade 4 rotates to be about to contact the sharpener 5, the semicircular blade 4 can gradually cut into the sharpener 5 through the transition of the transition piece 13, so that the semicircular blade 4 gradually presses the sharpener 5 back through the transition piece 13;

[0076] Through this structural design, by setting the transition piece 13, an arc transition effect is achieved between the blade holder 3 and the blade of the semicircular blade 4. When the sharpener 5 is too protruding, the semicircular blade 4 can gradually cut into the sharpener 5 through the transition of the transition piece 13, and the sharpener 5 is gradually pressed back by the transition piece 13, thereby reducing the possibility of rigid interference, avoiding damage to the semicircular blade 4 due to rigid collision with the sharpener 5, and increasing the fault tolerance for position adjustment of the sharpener 5. Example 6

[0077] This embodiment provides a new type of knife roller, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0078] Furthermore, a plurality of circumferentially distributed semicircular grooves 14 are evenly spaced on the blade edge of the semicircular blade 4 , and a rounded transition is provided between the semicircular grooves 14 and the blade edge of the semicircular blade 4 .

[0079] With this structural design, by providing a plurality of semicircular grooves 14, after the semicircular blade 4 cuts the aluminum foil, the semicircular groove 14 of the semicircular blade 4 will not cut the aluminum foil, but will form a connection point on the aluminum foil that matches the diameter of the semicircular groove 14, making it convenient to tear off the aluminum foil;

[0080] Since the semicircular groove 14 and the blade of the semicircular blade 4 have a rounded transition, when the sharpener 5 is pressed on the semicircular blade 4 by the pulling force of the spring 10, it can work normally through the rounded transition when passing through the semicircular groove 14, thereby avoiding rigid interference between the sharpener 5 and the semicircular groove 14. Example 7

[0081] This embodiment provides a new type of knife roller, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0082] Furthermore, the semicircular blade 4 is detachably connected to the blade holder 3 via screws.

[0083] With this structural design, since the semicircular blade 4 is detachably connected to the blade holder 3 by screws, the semicircular blade 4 can be easily replaced when the service life of the semicircular blade 4 is about to end.

[0084] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the specification of the present application and the features in the embodiments can be combined with each other.
