[0001] The utility model belongs to aluminum plate strip winding technical field, specifically relates to a kind of cutting device for aluminum plate strip winding. BACKGROUND

[0002] Aluminum plate strip refers to the aluminum foil or aluminum strip made of aluminum as main raw material and other alloy elements. When the processed aluminum plate strip is wound, the aluminum foil strip wound to the required specification needs to be cut.

[0003] The Chinese patent document with the authorized announcement number CN219881434U discloses a cutting device for aluminum plate strip, which conveys the aluminum plate strip through the conveying belt rotating in the support, and controls the timing work of the cutting motor, so that the pull rod can reciprocate in the sliding groove inside the cross beam under the action of the cutting motor, thereby cutting the aluminum plate strip and realizing the fixed-length cutting of the aluminum plate strip.

[0004] However, in the prior art, when the aluminum plate strip is cut, it is easy to cause the cutting part to be not flat due to the small movement of the aluminum plate strip itself or insufficient tensioning. Therefore, a cutting device for aluminum plate strip winding is proposed. UTILITY MODEL CONTENTS

[0008] The fixing assembly includes a clamping piece that can clamp and pull the aluminum plate strip to ensure the quality of the cut, a scissor piece that can drive the clamping piece to move, and a driving piece that can adjust the distance between the clamping piece and the aluminum plate strip.

[0009] The scissor piece includes a scissor arm.

[0010] The clamping piece includes a support rod fixedly connected to the scissor arm, a second roller seat arranged between the scissor arm and the support rod, a spring movably connected to the outer side of the support rod, a limiting ring fixedly connected to the outer side of the support rod, and a pressure roller movably connected to the second roller seat.

[0011] Preferably, the scissor piece includes a U-shaped frame fixedly installed in the material guiding assembly, a support fixedly connected to the front and rear of the U-shaped frame, and two scissor arms movably connected to the support.

[0012] Preferably, the driving member comprises two-way cylinders fixedly installed at the front and rear of the U-shaped frame respectively, and the two-way cylinders are fixedly connected with transmission rods at the telescopic ends.

[0013] Preferably, the support is rotationally connected with the scissor arm.

[0014] Preferably, the scissor arm is slidingly connected with the transmission rod.

[0015] Preferably, the compression roller is arranged between the second roller seats which are located at the same horizontal position and have the same height.

[0016] Preferably, the scissor arm and the support rod are slidingly connected with the second roller seat, the support rod is slidingly connected with the spring, the support rod is threadedly connected with the limiting ring, and the second roller seat is rotationally connected with the compression roller.

[0017] The aluminum plate strip cutting device has the advantages that: when the aluminum plate strip needs to be cut, the compression roller which can move with the scissor arm and slide relative to the scissor arm under the resistance of the spring is used to clamp the aluminum plate strip, so that the compression roller can clamp the aluminum plate strip to prevent the aluminum plate strip from moving, and the aluminum plate strip can be pulled horizontally to tension the part of the aluminum plate strip located in the slitting assembly, thereby ensuring that the cutting part of the aluminum plate strip is smooth and flat.
