Description

Technical Field

[0001] The utility model relates to paper cutting equipment, in particular to a paper cutting blade mechanism of a paper cutter. Background Art

[0002] A paper cutter is a special device for cutting paper. When the paper cutter is working, the paper pile is pushed onto the paper cutting platform, and the cutter descends to cut the paper. In order to ensure that the cutter can cut all the paper, a knife strip is provided at the corresponding position of the paper cutting platform and the knife strip cooperates with the cutter to ensure that the paper at the bottom can also be cut. Since the knife strip frequently cooperates with the cutter for cutting, it will be deformed and damaged after a period of use. At this time, the knife strip needs to be replaced. The traditional paper cutter is a screw rod screwed under the groove where the knife strip is placed on the paper cutting platform. The screw rod is rotated to lift the knife strip, and then the knife strip is taken out of the groove for replacement. This structure requires workers to enter the bottom of the paper cutting platform and then rotate the screw rod. The operation is very inconvenient, and usually two people are required to cooperate for replacement, which is time-consuming and laborious. In addition, it is also necessary to punch a threaded hole on the paper cutting platform, which increases the difficulty of processing the paper cutting platform. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a paper cutting blade mechanism of a paper cutting machine for solving the above-mentioned problem.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] The paper cutting knife strip mechanism of the paper cutting machine includes a knife strip corresponding to the cutter, and a groove for placing the knife strip is arranged on the paper cutting platform. The invention is characterized in that when the knife strip is placed in the groove, the knife strip extends out of the groove, and also includes a swing arm hinged on the frame, one end of the swing arm is located below the part of the knife strip extending out of the groove, and when the swing arm is swung upward, the knife strip can be driven to escape from the groove.

[0006] The swing arm is L-shaped, and a jacking portion is extended from one end of the swing arm. The jacking portion is located below the portion where the blade extends out of the groove, and the other end of the swing arm forms a gripping portion.

[0007] Positioning blocks are arranged on both sides of the groove, and the two ends of the knife strip abut against the positioning blocks.

[0008] The positioning block is provided with a limiting step which can abut against the swing arm.

[0009] The paper cutting knife mechanism of the paper cutting machine of the above technical solution is provided with a swing arm. When the knife strip needs to be replaced, it is only necessary to control the swing arm to swing upward, thereby driving the portion of the knife strip extending out of the groove to be lifted, so that the knife strip can be easily removed from the groove for replacement. This replaces the traditional structure using screw ejection, greatly reduces the labor intensity of workers, and also reduces the processing difficulty of the cutting knife platform.

[0016] As shown in the figure, the paper cutting blade mechanism of the paper cutting machine disclosed in the utility model includes a blade 2 corresponding to the cutter, a groove 6 for placing the blade 2 is provided on the paper cutting platform 1, when the blade 2 is placed in the groove 6, the blade 2 extends out of the groove 6, and also includes a swing arm 4 hinged on the frame, one end of the swing arm 4 is located below the portion of the blade 2 extending out of the groove 6, when the swing arm 4 swings up, it can drive the blade 2 to escape from the groove 6. Specifically, the swing arm 4 is L-shaped, one end of the swing arm 4 is extended with a jacking portion 7, the jacking portion 7 is located below the portion of the blade 2 extending out of the groove, and the other end of the swing arm 4 forms a gripping portion 5. Positioning blocks 3 are provided on both sides of the groove, and the two ends of the blade 2 are abutted against the positioning blocks 3, so that the left and right positioning of the blade 2 in the groove 6 can be achieved, and the stability of the position where the blade is placed can be ensured. The positioning block 3 is provided with a limiting step 8 that can abut against the swing arm 4, which can limit the position and swing direction of the swing arm 4, and ensure that the swing arm 4 can stably drive the blade 2 to move.

[0017] The paper cutting blade mechanism of the paper cutting machine of the utility model, when the blade 2 needs to be replaced, controls the swing arm 6 to swing, and its lifting part 7 drives the blade 2 to be lifted and then disengaged from the groove 6, so as to replace the blade, replacing the traditional structure using screw ejection, greatly reducing the labor intensity of workers, and also reducing the processing difficulty of the cutting blade platform.
