Description

Technical Field

[0001] This utility model relates to the technical field of plastic film processing equipment, specifically a slitting machine for processing PE plastic film. Background Technology

[0002] Polyethylene plastic film is widely used in packaging, agricultural covering, industrial lining and other fields due to its excellent physical properties, chemical stability and cost-effectiveness. With the increasing market requirements for the precision, efficiency and environmental protection of film products, the slitting and processing of PE film has become a key step affecting product quality and production efficiency. Therefore, it is particularly important to develop a slitting machine for PE plastic film processing in order to carry out efficient slitting operations.

[0003] A slitting machine for processing PE plastic film, as described in reference announcement number CN220364098U, includes a slitting table. A slitting mechanism and a winding mechanism are respectively arranged at the top center and on both sides of the slitting table. The slitting mechanism includes a U-shaped plate, a rotating block movably connected to the inner side of the U-shaped plate, and blades respectively sleeved on both sides of the rotating block. The winding mechanism includes a turntable, second clamping blocks movably connected above and below the facing surfaces of the turntable, and winding rollers located between adjacent turntables. This slitting machine solves the problem of inconvenient blade loading and unloading by using a fastening nut to clamp the blades onto the rotating block in the slitting mechanism. Similarly, the winding mechanism uses a second threaded rod to drive the second clamping block to move relative to the turntable, thereby clamping the winding rollers onto the turntable, solving the problem of inconvenient loading and unloading of the winding rollers. As can be seen from the above, although this slitting machine can be applied well, it is generally inconvenient to adjust the spacing between the slitting blades, making it difficult to slit PE plastic film to a specified width, and further improvements are needed.
