Description

Technical Field

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

[0002] A slitter 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 various widths. Different materials and finished product specifications require different slitting widths, so the spacing between the blades on the slitter needs to be adjusted to meet different specifications.

[0003] However, the existing slitting machines usually require manual operation when adjusting the distance between the blades. However, since the blades are relatively sharp, there are certain safety hazards when adjusting manually. Secondly, when adjusting, it is usually necessary to use measuring tools to measure and then move the blades. The adjustment process is not only very cumbersome, but also restricted by the position of various mechanisms inside the machine, resulting in the entire manual adjustment process being time-consuming, labor-intensive, and difficult to operate. In addition, the error in the distance between a single set of blades has a great impact on the spacing of the entire set of blades, which can easily cause the spacing between the blades to be inaccurate, resulting in inaccurate cutting when slitting the product, resulting in a large number of defective products. Especially when cutting precious metals, a slight error will make the entire section of precious metal material cut unusable, causing huge economic losses to the producer.

[0004] In summary, an automatic knife adjusting mechanism for a slitting machine is proposed. Utility Model Content

[0011] Preferably, each of the blades is provided with an annular groove, and the annular groove is used for limiting cooperation with the clamping arm.

[0012] Preferably, the two clamping arms are further provided with convex portions formed on the inner walls of the clamping arms; the convex portions are correspondingly limitedly matched with the annular grooves to clamp the blade that needs to be adjusted.
