Description

Technical Field

[0001] The utility model relates to the technical field of seafood processing, in particular to a cutting structure of a seafood vacuum packaging machine. Background Art

[0002] Seafood needs to be cut when it is vacuum packed. Cutting is to ensure that the size of the packaging bag is suitable for the seafood being packaged, and it also helps to improve the sealing performance and aesthetics of the packaging. When cutting, it is necessary to ensure that the size of the packaging bag is large enough to accommodate the seafood and can be completely sealed to ensure the vacuum effect and preservation effect.

[0003] In the prior art, for example, a Chinese patent with publication number CN221315320U discloses a packaging bag cutting mechanism with high cutting flatness, including a lathe, a position adjustment component and a cutting component; the lathe: lathe legs are respectively provided on the front and rear sides of the right end of the bottom surface, the left side of the bottom surface of the lathe is provided with evenly distributed lathe feet, the left side of the upper surface of the lathe is provided with a punching die, and the front and rear inner walls of the lathe are rotatably connected with evenly distributed guide rollers; the position adjustment component is arranged on the left side of the upper side of the lathe; the cutting component is arranged inside the position adjustment component, and the cutting component corresponds to the upper and lower positions of the punching die.

[0004] Although the above device can complete the cutting of packaging bags, in actual use, the cutter is driven by an electric telescopic rod to complete its work, which has requirements on the driving force and stability of the electric telescopic rod. The initial speed of the cutter is consistent with the contact speed with the packaging bag. If the driving speed of the telescopic rod is insufficient, the contact speed between the cutter and the packaging bag will be insufficient. The slow cutting speed will result in incomplete cutting or the packaging bag being pulled, affecting the flatness and cutting quality of the packaging bag. For this reason, we propose a cutting structure of a seafood vacuum packaging machine to solve the above problems. Utility Model Content
