[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 3 As an embodiment provided by the present utility model: A cutting knife with anti-wear function for ice cream packaging includes a mounting frame 1 for supporting the whole device. A motor 2 for driving the whole device to operate is installed at the right end of the mounting frame 1. The motor 2 is a prior art and can start working by connecting to the power supply. Due to the prior art, this case will not be described in detail. A cutting assembly 3 for cutting the packaging bag is arranged at the left end of the mounting frame 1. The cutting assembly 3 includes a cutting shaft 31 for supporting the rotation of the whole cutting assembly 3. The cutting shaft 31 penetrates and is rotatably connected to the left end of the mounting frame 1. The left end of the output shaft of the motor 2 is fixedly connected to the right end of the cutting shaft 31. By starting the motor 2, the cutting shaft 31 can be driven to rotate. A matching assembly 4 for cooperating with the cutting assembly 3 to perform cutting is arranged at the bottom left end of the mounting frame 1 close to the cutting assembly 3. The matching assembly 4 includes a driven shaft 41 for driving the support seat 42 to rotate. The driven shaft 41 is rotatably connected to the left end of the mounting frame 1. The driven shaft 41 and the cutting shaft 31 are connected by a belt drive. When the cutting shaft 31 rotates, it will drive the driven shaft 41 to rotate synchronously through the belt.

[0031] Refer to Figure 1 - Figure 3, the cutting assembly 3 further includes a protective sleeve 32 for protecting the cutting blade 35. The bottom end of the protective sleeve 32 is fixedly connected to the top end of the cutting shaft 31. When the cutting shaft 31 rotates, it will drive the protective sleeve 32 to rotate synchronously. The top end of the protective sleeve 32 penetrates and is slidably connected to a cutting blade 35 for cutting the packaging bag. The left end of the cutting blade 35 is fixedly connected to a slide bar 33 for driving the cutting blade 35 to move. A chute 34 for the slide bar 33 to move is provided at the left end of the protective sleeve 32. The slide bar 33 slides on the inner wall of the chute 34, and the slide bar 33 can slide up and down inside the chute 34. The left end of the mounting frame 1 is fixedly connected to a cam 37 for pressing the slide bar 33. The cutting shaft 31 penetrates and is rotatably connected to the left end of the cam 37.

[0032] Refer to Figure 2 - Figure 4 , a return spring 36 for driving the cutting blade 35 to move is fixedly connected to the bottom end of the protective sleeve 32. The bottom end of the return spring 36 is fixedly connected to the inner wall of the protective sleeve 32. The return spring 36 will always pull the cutting blade 35 towards the inside of the protective sleeve 32. The cooperating assembly 4 further includes a support seat 42 for cooperating with the cutting blade 35 for cutting. The top end of the support seat 42 is fixedly connected to the bottom end of the driven shaft 41. When the driven shaft 41 rotates, it will drive the support seat 42 to rotate. A cutting surface 351 for pressing and cutting the packaging bag is provided at the left end of the cutting blade 35. The cutting blade 35 is only provided with a single cutting surface 351. Compared with a double-edged cutting blade, the cutting blade 35 has a longer service life when in use. An arc surface 352 for supporting the blade part of the cutting blade 35 is provided at the right end of the cutting blade 35. During cutting, the arc surface 352 will play a role in supporting the whole cutting blade 35, so as to prevent the cutting surface 351 from bending and breaking to the left when the cutting blade 35 is pressed. A cutting groove 421 for accommodating the cutting blade 35 is provided at the bottom end of the support seat 42. A guiding groove 422 for pushing the packaging bag is provided at the right end of the driven shaft 41. During cutting, the guiding groove 422 can gradually fit with the arc surface 352, so as to guide the cutting blade 35 to better fit with the cutting groove 421. The cutting groove 421 and the cutting blade 35 are adapted to each other. When the cutting blade 35 is inserted into the inside of the cutting groove 421, the packaging bag inside the cutting groove 421 can be cut off.

[0033] Working principle: By starting the motor 2, the cutting shaft 31 can be driven to rotate clockwise. The cutting shaft 31 will drive the passive shaft 41 to rotate in the same direction through a belt. When the protective sleeve 32 rotates until the opening faces downward, the slide rod 33 will be extruded by the cam 37 and move outward. The outward movement of the slide rod 33 will drive the cutting knife 35 to move outward synchronously. At the same time, the support seat 42 also just opens upward under the drive of the passive shaft 41. In this way, the cutting knife 35 can gradually cut into the inside of the cutting groove 421 by relying on the fit between the guiding groove 422 and the arc surface 352. In this way, the cutting of the packaging bag can be completed. As the cutting shaft 31 and the passive shaft 41 continue to rotate, the cutting knife 35 and the support seat 42 will separate, waiting for the next cutting.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
