Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, specifically, it relates to a cutting mechanism for a film cutting machine and the film cutting machine itself. Background Technology

[0002] In modern production, efficient and precise cutting operations are key to improving production efficiency and product quality. Traditional cutting equipment often suffers from problems such as complex operation, insufficient precision, and inconvenient adjustment, making it difficult to meet the market's demand for high-precision and diversified cutting.

[0003] Utility model CN220299948U relates to the field of PE film processing equipment, disclosing a PE film cutting mechanism, including a cutting box. A drive shaft is rotatably connected to the bottom left and right sides of the inner walls at both ends of the cutting box. A conveyor belt is meshed with the outer diameter of the drive shaft. Several neatly arranged pressing protrusions are fixedly connected to the outer wall of the conveyor belt. A first receiving plate is fixedly connected to the top left and right sides of the conveyor belt on the inner walls at both ends of the cutting box. A pressing roller is slidably connected to the inner wall of the bottom end of each of the first receiving plates. In this utility model, by setting an eccentric rod and a connecting rod, the cutting blade can slide up and down the inner wall of the second receiving plate under the action of a second motor driving the eccentric rod to rotate. This allows the connecting rod to drive the cutting blade to slide up and down at a certain frequency on the conveyor belt, thus facilitating the control of the length of the cut PE film and meeting the needs for PE films of different lengths.

[0004] However, the aforementioned patent still has the following problems: the cutting mechanism in this patent is mainly designed for thinner materials such as PE film. When dealing with thicker film materials, especially when the short blade is cutting thicker films, insufficient cutting and uneven edges may occur due to the limitation of cutting force, which seriously affects the cutting effect and subsequent use of the film. During the cutting process, the film material often experiences positional displacement due to the influence of conveying speed, cutting force, and its own inertia. This displacement not only leads to a decrease in cutting accuracy but may also cause waste of film material and damage to the cutting equipment.

[0005] In view of this, this utility model is proposed. Utility Model Content
