[0007] Furthermore, the paper pressing board is a strip-shaped board structure and one side adjacent to the rotating roller is bent upward.

[0008] Furthermore, the trolley also includes a trolley back plate, a lower knife fixing plate, a fixing bracket, a lower knife fixing bearing seat, a bearing, a bearing sleeve, a screw and a spring structure. There are two fixing brackets and they are fixed on one side of the trolley back plate. There are four walking wheels and they are evenly distributed on the other side of the trolley back plate. The four walking wheels are located two above the guide rail beam and two below the guide rail beam. The lower blade is a circular blade. The lower blade is fixed to the lower blade fixing plate by a lower blade fixing bearing seat, a bearing, a bearing sleeve and a screw. The lower end of the lower blade fixing plate is fixed in the middle of the two fixing brackets by a rotating shaft and can be flipped up and down. The upper end of the lower knife fixing plate cooperates with the upper part of the trolley back plate through a spring structure.

[0009] Furthermore, a belt buckle is provided on one side of the back plate of the trolley adjacent to the small walking wheel, and a driving belt is provided on the belt buckle, and the driving belt is connected to a driving motor and driven by the driving motor.

[0012] The white steel knife is installed on the base assembly to form an inclined angle, forming a cutting angle with the lower blade of the trolley assembly. The trolley assembly moves back and forth through the motor, and the lower blade passively rolls back and forth on the white steel knife to complete the paper cutting action. The paper press cooperates with the base assembly to complete automatic paper feeding.

[0013] The lower knife fixed bearing seat is installed together with the shaft in a tight fit, the lower knife is installed on the lower knife fixed bearing seat, and is fixed to the lower knife fixed plate through a bearing. The lower knife can rotate flexibly, and the lower knife fixed plate is connected to the lower knife fixed plate through a rotating shaft. The lower knife fixed plate is supported by a trolley compression spring so that the lower knife always has a backward force.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The semi-automatic cutting device described in the present invention can firstly greatly reduce the labor intensity of this type of work in this industry, and the cutting accuracy and the effect of the incision are also greatly improved. During the automatic feeding process, the sensor senses the relative position of the material and drives the cutting carriage to move left and right, thereby cutting the material. Since the upper and lower knives are circular knives and the straight knives are made of high-speed steel, due to the corresponding movement relationship, the hardness of the circular knife is greater than that of the straight knife, thereby maximizing the tool life.
