Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a cutting mechanism for environment-friendly bio-based degradable materials. Background Technique

[0002] Environment-friendly bio-based degradable materials refer to materials synthesized by physical or chemical methods using renewable resources (such as plants, microorganisms, etc.) that can be completely decomposed by microorganisms into low-molecular compounds under natural environmental conditions. Such materials are of great significance in reducing environmental pollution and promoting sustainable development, and include degradable plastic films.

[0003] In the prior art, a patent document with the publication number CN219466231U discloses a cutting machine for processing degradable materials, including a frame. A positioning mechanism is arranged inside the frame, and a cutting mechanism is arranged on the upper end surface of the frame; the utility model has a simple structure and reasonable design. By using the motor as the power output source to indirectly and synchronously drive the two side pressure rollers to move up and down, the flatness of the whole film can be ensured during cutting, and the probability of wrinkles can be reduced. At the same time, a spring is arranged between the first limiting plate and the second limiting plate to achieve the effect that the pressure roller gradually rises after the motor rotates, thereby reducing manual operation and improving production efficiency. On the other hand, the knife plate is driven to move up and down indirectly by a cylinder to cut the film. During cutting, the limiting wheels on both sides of the knife plate can effectively play a limiting role to ensure that the longitudinal movement track of the knife plate is not changed, and the cutting effect of the product is improved.

[0004] During the use process, it is found that the above device needs to operate two groups of pressure rollers to press the plastic film through the motor, and then operate the cutting edge of the cutter through the cylinder to cut the plastic film, and the connection smoothness needs to be further improved.
