[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1 See also Figures 1-8 The present invention provides a technical solution: a cutting device for hand-grabbed pancake film, comprising a cutting machine body 1, a film coating roller 11 is arranged above the cutting machine body 1, a film 12 is wrapped around the outer periphery of the film coating roller 11, and the film coating roller 11 is rotatably connected to the cutting machine body 1; The cutting tool 2 includes a scoring knife 21 and a cutting knife 22 provided above the cutting machine body 1. The scoring knife 21 can cut the film 12 longitudinally, and the cutting knife 22 can cut the film 12 transversely. The guide mechanism 3 is located on both sides of the cutter 21 and can push the diaphragm 12 to move when the cutter 21 cuts the diaphragm 12; A pressing mechanism 4 , located on both sides of the cutter 22 , capable of pressing the diaphragm 12 when the cutter 22 cuts the diaphragm 12 ; When the present invention is in use, the film 12 on the periphery of the coating roller 11 is driven by the guide mechanism 3 to pass through the guide wheel 32, so that the film 12 covers the top of the hand-grabbed pancake, and the film 12 is cut longitudinally by the cutting knife 21 when the film 12 slides. After the longitudinal cutting is completed, the cutter 22 cuts the film 12 transversely under the drive of the driving motor 43. The longitudinal cutting is performed first, and then the transverse cutting is performed, ensuring that the film 12 can be accurately cut according to the preset size and shape, meeting the requirements of hand-grabbed pancake packaging. The precise cutting reduces the waste of the film 12 caused by improper cutting, reduces the scrap rate, and saves costs. The cut surface of the film 12 is pressed by the pressing mechanism 4, which effectively avoids the film 12 from sticking to the cutter 22, ensures the smooth cutting and the cleaning of the cutter 22, and facilitates the film 12 on the upper and lower sides of the hand-grabbed pancake to come closer, thereby better wrapping the hand-grabbed pancake and improving the tightness and aesthetics of the packaging.

[0018] The pressing mechanism 4 includes a roller 41 provided above the cutting machine body 1, the roller 41 being rotatably connected to the cutting machine body 1, the cutter 22 being located on the periphery of the roller 41 and fixedly connected to the roller 41, the end of the roller 41 being located outside the cutting machine body 1, the periphery of the roller 41 being sleeved with a belt 1 42, the interior of the belt 1 42 being provided with a drive motor 43, the periphery of the drive motor 43 being sleeved with the belt 1 42, and the outer wall of the drive motor 43 being fixedly connected to the cutting machine body 1; After the diaphragm 12 wraps the hand-grabbed pancake, the diaphragm 12 is located above the cutting machine body 1 and slides through the guide mechanism 3. The driving motor 43 drives the roller 41 to rotate through the belt 42. The cutter 22 on the periphery of the roller 41 cuts the diaphragm 12 horizontally while following the rotation of the roller 41. The roller 41 and the cutter 22 are driven by the driving motor 43 and the belt 42 to perform horizontal cutting, thereby realizing the automation of the cutting process, reducing the need for manual operation, and improving production efficiency. The cutting of the diaphragm 12 can be completed while it slides above the cutting machine body 1 without stopping the transmission, thereby ensuring the continuity and efficiency of the production line. The cutting method in which the roller 41 drives the cutter 22 to rotate avoids the jitter or uneven force that may occur during manual cutting, thereby ensuring the flatness and smoothness of the cutting surface.

[0019] The guide mechanism 3 includes a rotating rod 31 provided inside the cutting machine body 1, the rotating rod 31 being rotatably connected to the cutting machine body 1, and a guide wheel 32 being fixedly connected to the outer wall of the rotating rod 31. The guide wheels 32 are located on both sides of the cutting blade 21, and the lower ends of the guide wheels 32 abut against the upper end of the cutting machine body 1; The outer periphery of the roller 41 is sleeved with the second belt 33, the second belt 33 is located inside the cutting machine body 1, and the second belt 33 is sleeved on the outer periphery of the rotating rod 31; When the cutting blade 21 is cut, the guide wheel 32 not only drives the film 12 to move, but also presses the film 12 of the guide wheel 32 on the film 12 to reduce the resistance during cutting, making the cutting smoother. The auxiliary cutting effect of the guide wheel 32 can reduce burrs and tearing during cutting, and improve the cutting quality. At the same time, due to the accurate cutting position, the beautiful appearance of the hand-grabbed pancake packaging is also guaranteed.

[0020] The roller 41 defines a sliding groove 44 on both sides of the cutter 22. A fixing rod 45 is fixedly connected to the inner wall of the sliding groove 44. A pressing rod 46 is slidably connected to the inside of the sliding groove 44. A pressing groove 47 is defined in the center of the pressing rod 46. The fixing rod 45 is located inside the pressing groove 47 and is slidably connected to the pressing groove 47. The pressing rod 46 is arc-shaped at one end close to the cutter 22; When the cutter 22 cuts the film 12 transversely, when the cutter 22 is directed vertically downward, the pressing rod 46 located inside the sliding groove 44 slides with the fixed rod 45 through the provided pressing groove 47, and the pressing rod 46 slides out of the sliding groove 44 and presses the cut surfaces of the film 12 on both sides of the cutter 22. On the one hand, this prevents the cut surface of the film 12 from adhering to the cutter 22 and following the cutter 22 to rotate around the roller 41, thereby preventing the cut surface of the film 12 from warping due to adhesion. On the other hand, the pressing rod 46 presses the cut surface of the film 12, thereby preventing the cut surface of the film 12 from warping due to following the cutter 22 to rotate around the roller 41, thereby ensuring that the edge of the film 12 is smooth after cutting, thereby improving the overall quality of the packaging. In addition, the arc-shaped design of the end of the pressing rod 46 makes the end surface of the pressing rod 46 smoother, reducing the contact area and friction between the pressing rod 46 and the diaphragm 12, which helps prevent the diaphragm 12 from sticking to the pressing rod 46 during the pressing process, ensuring the smooth progress of the cutting and packaging process. The smooth arc surface can also reduce the generation and accumulation of static electricity, further reducing the risk of the diaphragm 12 sticking to the pressing rod 46 due to static electricity. The arc-shaped design avoids sharp corners or edges at the end of the pressing rod 46, thereby reducing the risk of scratching or tearing the diaphragm 12 during the pressing process, helping to maintain the integrity and aesthetics of the diaphragm 12, and improving the packaging quality. Moreover, the arc-shaped pressing rod 46 can distribute pressure more evenly when pressing the diaphragm 12, avoiding deformation or damage of the diaphragm 12 due to excessive local pressure.

[0021] The pressing rod 46 is fixedly connected to a grinding stone 48 at one end close to the cutter 22 , and the grinding stone 48 is closely attached to the outer wall of the cutter 22 ; Each time the cutter 22 cuts the diaphragm 12, the pressing rod 46 located inside the roller 41 will slide out and press the diaphragm 12. Each time the pressing rod 46 slides, the grinding stone 48 located at the end of the pressing rod 46 near the cutter 22 grinds the cutter 22 to ensure that the cutter 22 always remains sharp, avoiding incomplete cutting, burrs or tearing caused by the cutter 22 becoming blunt, improving the cutting quality, and reducing the wear and dullness of the cutter 22 caused by long-term use through real-time grinding, thereby extending the service life of the cutter 22 and reducing the frequency and cost of replacing the cutter 22. The cutter 22 is automatically ground by the grinding stone 48, reducing the need and frequency of manual maintenance, simplifying the maintenance process, and reducing maintenance costs and time costs.

[0022] The working principle and use process of the present invention are as follows: when the driving motor 43 is started, the driving motor 43 drives the roller 41 to rotate through the belt 1 42. At the same time, the roller 41 drives the rotating rod 31 to rotate through the belt 2 33. Since the guide wheel 32 is located at the periphery of the rotating rod 31 and is fixedly connected to the rotating rod 31, when the rotating rod 31 rotates, the lower end of the guide wheel 32 presses the diaphragm 12 and drives the diaphragm 12 to transmit. When the cutter 21 performs longitudinal cutting, the guide wheel 32 not only drives the diaphragm 12 to move, but the pressure of the guide wheel 32 on the diaphragm 12 can also reduce the resistance during cutting, making the cutting smoother. After the diaphragm 12 clamps the hand-grabbed pancake, the diaphragm 12 is located above the cutting machine body 1 and slides through the guide mechanism 3, and the driving motor 4 The roller 41 is driven to rotate by the belt 142. The cutter 22 on the outer periphery of the roller 41 cuts the film 12 transversely while following the rotation of the roller 41. When the cutter 22 cuts the film 12 transversely, when the cutter 22 is oriented vertically downward, the pressing rod 46 located inside the sliding groove 44 slides through the provided pressing groove 47 and the fixed rod 45. The pressing rod 46 slides out of the sliding groove 44 and presses the cut surfaces of the film 12 on both sides of the cutter 22. Each time the cutter 22 cuts the film 12, the pressing rod 46 located inside the roller 41 slides out and presses the film 12. Each time the pressing rod 46 slides, the grinding stone 48 located at the end of the pressing rod 46 near the cutter 22 grinds the cutter 22.

[0023] Example 2 A method for cutting a hand-grabbed pancake film comprises the following steps: S1, the hand-pulled pancake is clamped by the film 12 on the upper and lower sides of the film roller 11, and moves above the cutting machine body 1 through the guide mechanism 3. The cutting knife 21 inside the guide mechanism 3 cuts the film 12 longitudinally; S2, when the diaphragm 12 passes through the cutter 22, the cutter 22 cuts the diaphragm 12 horizontally, so that the diaphragm 12 is cut and separated; S3. When the cutter 22 cuts the film 12, the pressing mechanism 4 located inside the roller 41 presses the cut surface of the film 12 to prevent the film 12 from adhering to the surface of the cutter 22.
