Description

Technical Field

[0001] The utility model belongs to the field of slitting machines, in particular to a cutter pressing device. Background Art

[0002] Aluminum foil slitting machine is a mechanical equipment for slitting and trimming aluminum foil materials. Its main function is to slit wide aluminum foil into multiple narrow aluminum foils of specific width and length through a cutting process. It is generally composed of unwinding, main machine, traction, rewinding, and waste discharge. The semi-finished products slit on the slitting machine are a process of unwinding and rewinding. This process includes two parts: machine speed control and tension control. The slitting machine plays a key role in achieving the slitting function. The cutter is frequently replaced and needs to be easily disassembled. After the cutter is installed, due to the high precision required for this part, the errors of various parts are accumulated and amplified to the cutter, resulting in large jitter on the cutter end face. The quality of the finished aluminum foil trimming is poor and wavy lines are prone to appear, so the jitter of the knife needs to be controlled.

[0003] In the prior art, the removal of the slitting machine cutter requires two tools to operate at both ends of the cutter. A wrench is used to fix the shaft at one end to prevent relative rotation, and a hexagon socket screw is used to remove the screw at the other end. Each removal is difficult, and because the cutter is sharp, the removal screw is close to the cutter, which can easily cause the risk of cuts. The installation position of the blade must ensure good end face runout, which requires an adjustable mechanism at the installation position of the cutter. The adjustment of the end face runout of the cutter mainly relies on the adjustment of the gasket between the cutter seat and the cutter gasket (the installation relationship between the cutter seat, the cutter gasket, and the cutter is as follows Figure 1 As shown in the figure, since it is necessary to ensure that the runout of the cutter installation end face is as small as possible, the gasket to be plugged will be smaller, and more points need to be plugged with gaskets. The installation of small gaskets at multiple points will cause great difficulties for the operator to adjust, and the adjustment will be time-consuming and inconvenient. Utility Model Content
