Description

Technical Field

[0001] The utility model relates to the technical field of upper and lower cutting knife mechanisms of slitting machines, in particular to an upper and lower cutting knife mechanism of a slitting machine. Background Art

[0002] Slitting machine is a mechanical equipment used to cut materials longitudinally or transversely. It is widely used in textile, plastic, paper, metal and other industries. The main function of slitting machine is to cut raw materials or finished products according to certain sizes or specifications to meet the needs of different process production and processing. However, the upper and lower cutting mechanisms of existing slitting machines still have certain defects when in use.

[0003] At present, when the existing slitting machines are in use, their cutters can only be used for thin film materials with smaller thickness, so the overall practicality is low. When cutting thicker materials, there may be a situation where the cutting is not continuous, and a large amount of powder will be generated during the cutting, which affects the overall cutting environment. The powder scattered in the air not only makes the overall cutting inconvenient, but also affects the user's respiratory tract.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the upper and lower cutting knife mechanisms of the original slitting machine. Therefore, we proposed that the upper and lower cutting knife mechanisms of the slitting machine can solve the above problems well. Utility Model Content
