An upper cutter is fixed at the lower part of the upper blade plate, and a lower cutter and a lower blade plate are provided below the upper cutter. The bottom of both ends of the lower blade plate are provided with support blocks fixed to the frame plate. An adjustment plate is fixed to the front side of the support block. An adjustment screw is threadedly connected to the adjustment plate. The inner end of the adjustment screw contacts the front side wall of the lower blade plate. Both ends of the lower blade plate are provided with strip-shaped adjustment holes along the front and rear direction. Fastening bolts are provided in the adjustment holes. Fixed support plates that can be detachably fixed to the frame plate are provided on both sides of the upper blade plate. A sliding guide plate is fixed to the inner side of the fixed support plate by bolts. The inner side of the sliding guide plate is provided with an L-shaped guide groove that mates with the end face and side wall of the upper blade plate.

[0005] As a preferred embodiment, the lower end of the upper blade plate is provided with multiple positioning pins along the horizontal direction, the upper cutter has positioning holes that mate with the positioning pins, and the rear side of the upper cutter is provided with fixing bolts to fix the upper blade plate. Through the insertion and engagement of the positioning pins and positioning holes, the upper cutter and the upper blade plate can be quickly and accurately pre-positioned during assembly, and the fixing bolts on the rear side are used to lock and fix the blade, preventing it from loosening or shifting.

[0006] As a preferred embodiment, the outer wall of the guide groove is an inclined slope, the front side wall of the frame plate above the support block is provided with an avoidance notch, and a pressure plate is fitted on the fastening bolt. The pressure plate is located above the lower blade plate to better prevent the lower blade plate from loosening after being pressed.

[0007] As a preferred embodiment, the lifting drive mechanism includes connecting plates fixed to the top of both ends of the upper blade plate, connecting sleeves fixed to the top of the connecting plates, two reinforcing horizontal plates provided above the upper blade plate, the two ends of the reinforcing horizontal plates being fixed to the frame plate, and cutting cylinders installed on the reinforcing horizontal plates, with the bottom of the piston rod of the cutting cylinders being fixed to the connecting sleeves.

[0008] As a preferred embodiment, the reinforcing cross plate has mounting notches at both ends, and L-shaped mounting plates are welded and fixed to the mounting notches of the front and rear reinforcing cross plates. The cutting cylinder is fixedly mounted on the mounting plates. By setting mounting notches at the ends of the reinforcing cross plates and welding them with L-shaped mounting plates, the installation position of the cutting cylinder can be accurately positioned.

[0009] As a preferred embodiment, a reinforcing rib plate 1 is fixed on the mounting plate, a reinforcing rib plate 2 is provided on the outer side of the fixed support plate, and a reinforcing rib plate 3 is fixed on the rear bottom of the connecting plate. The reinforcing rib plate 3 is welded and fixed to the upper blade plate to increase the strength of the equipment.

[0010] As a preferred option, multiple intersecting reinforcing ribs are welded and fixed to the rear side wall of the upper blade to increase its strength.

[0011] As a preferred embodiment, the rear top of the lower blade plate is provided with a positioning support recess to support the lower cutter, limiting the horizontal displacement and vertical runout of the lower cutter, ensuring that the lower cutter is installed stably and positioned accurately. Support plates are fixed on both the front and rear sides of the top of the lower blade plate. A detachable support plate is fixed to the top of the support plate by bolts. The detachable support plate can stably support the aluminum foil to be processed before cutting, preventing the aluminum foil from hanging and drooping or wrinkling, and ensuring accurate cutting position. There is a gap between the two support plates. The bottom of the support plate is provided with a limiting boss that extends into the gap. The two ends of the gap are fixed with mounting nuts. The mounting nuts are connected to fixing bolts. Some auxiliary devices, such as sensor mounting brackets, can be installed by using the fixing bolts and mounting nuts.

[0012] As a preferred embodiment, the bottom of the lower blade is bolted to a removable protective base plate, with clearance recesses at both ends of the protective base plate. The protective base plate supports the bottom center of the lower blade, preventing it from bending and deforming under stress during cutting.

[0013] This utility model has the following beneficial effects: The lower blade is supported by a support block. Rotating the adjusting screw can push the lower blade to move back and forth. With the help of the strip-shaped adjustment hole, the cutting gap between the upper and lower blades can be precisely adjusted. After adjustment, the blade is locked by the fastening bolt to resist shearing vibration, prevent the lower blade from shifting, ensure the stability of the aluminum foil cutting gap, and reduce burrs on the cut.

[0014] The sliding guide plate is equipped with an L-shaped guide groove, which simultaneously limits and guides the upper blade end face and side wall in both directions, increasing the guiding mating area and suppressing the swaying and shaking of the upper blade during shearing. The fixed support plate is detachable, and the sliding guide plate is bolted together. After wear, the sliding guide plate can be replaced separately, reducing maintenance costs.
