Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting devices, in particular to a hydraulic lifting and cutting mechanism. Background Art
[0002] Steel wire is a commonly used packaging material in the packaging and conveying field, and its cutting efficiency is directly related to the duration and quality of the entire packaging line. In order to improve the efficiency of cutting, those skilled in the art have proposed a series of cutting devices, such as the Chinese patent with the authorization announcement number CN218875556U, which discloses a plastic film cutting device, which moves downward through a movable plate, thereby driving two pressing components and a blade to move downward. Through the downward movement of the two pressing components, the two sides of the plastic film cutting position can be pressed and clamped, thereby ensuring the stability of subsequent blade cutting. However, the downward movement of the pressing component adopted in this scheme has limited applicability and is not flexible enough. It cannot cut materials with longer lengths or certain bends. The structure is relatively complex, and cumbersome adjustments and calibrations are required for different cutting requirements, which increases the difficulty of operation and production costs.
