Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a knife-supporting mechanism for slitting machines. Background Art

[0002] A slitting machine is a precision cutting machine that slits large rolls of paper, film, non-woven fabric, aluminum foil, mica tape, precious metals, and other materials into sheets of varying widths. As the specifications of the rolls change, the depth of the blade's insertion into the slitting groove on the carrier shaft—the blade's position—must be adjusted to achieve the best slitting results.

[0003] However, when adjusting the blade, the existing slitting machines mostly rely on the personal experience of the operator, and the adjustment effect cannot be guaranteed. When the adjustment gap is too large, the slitting effect is not good, and when the gap is too small, the blade wears too quickly, which affects the service life of the blade. Secondly, the blade wears during the product slitting process, and the worn blade needs to be replaced to ensure the slitting effect. However, the spacing between the blades will change during the replacement process, resulting in the blades not being able to correspond to the slitting grooves on the carrier shaft, and the blades need to be adjusted. In addition, the knife shaft needs to be reinstalled during the knife changing process, and the adjusted blade will move during the installation process. Manual adjustment of the blade is required to ensure that the blade corresponds to the slitting grooves on the carrier shaft, and then the knife adjustment is performed. The whole process is time-consuming and labor-intensive, which greatly affects the production efficiency of the product. In addition, during the adjustment process, since the blade is relatively sharp, there are certain safety hazards when adjusting manually.

[0004] In summary, a knife-supporting mechanism for a slitting machine is proposed. Utility Model Content
