Description

Technical Field

[0001] The utility model relates to the technical field of cutting knife groups, in particular to a cutting knife group structure of a band saw paper cutter. Background Art

[0002] Paper cutter is a commonly used industrial equipment, mainly used for cutting various materials such as paper, cardboard, leather, rubber, etc. According to different uses and occasions, paper cutters can be divided into many types, such as manual paper cutters, electric paper cutters, CNC paper cutters, band saw paper cutters, etc. Paper cutters are usually composed of cutting knife groups, transmission systems, paper pressing devices, bases, etc. Among them, the cutting knife group is the core component of the paper cutter, which is responsible for completing the paper cutting work.

[0003] Common paper cutters generally clamp the paper material through a limit device, and then cut it through a cutting knife group. The cutting knife group is generally composed of a motor, a turntable and a knife belt. The motor drives the turntable to rotate, thereby driving the knife belt to rotate, and the paper material is cut by the knife belt. However, when the knife belt cuts the paper, a large amount of paper scraps will be absorbed by the surface of the knife belt. When a cleaning block is used to clean the paper scraps absorbed by the knife belt, a large amount of paper scraps will also be absorbed by the surface of the cleaning block. After the paper scraps on the surface of the cleaning block accumulate for a long time, the paper scraps are easily squeezed by the subsequent paper scraps and enter the inner cavity of the cleaning block, resulting in an increase in the friction between the cleaning block and the knife belt, affecting the stable operation of the knife belt. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a cutting blade group structure of a band saw paper cutter to solve the problem proposed in the above background technology that the surface of the cleaning block will also absorb a large amount of paper scraps. After the paper scraps on the surface of the cleaning block accumulate for a long time, the paper scraps are easily squeezed by the subsequent paper scraps and enter the inner cavity of the cleaning block, resulting in increased friction between the cleaning block and the blade belt, affecting the stable operation of the blade belt.

Cleaning rubber is installed on the inner wall of the cleaning plate. The lifting plate can be driven to rise and fall by the adjusting rod, thereby driving the cleaning plate to rise and fall. The cleaning rubber can clean the surface of the knife belt more cleanly.

[0012] Preferably, sliders are installed on both sides of the adjusting rod, and slide rails are welded on both sides of the bottom of the mounting plate. The sliders are embedded in the inner cavity of the slide rails. The sliders cooperate with the slide rails to limit the adjusting rod so that the adjusting rod can move vertically.

When there are a lot of paper scraps adsorbed on the surface of the cleaning plate, the coaxial counterclockwise rotation of the rotor of the stepper motor is started to drive the cleaning plate to move upward, and the cleaning plate will be separated from the surface of the knife belt. By driving the cleaning plate seat to reciprocate up and down, the paper scraps on the surface of the cleaning plate can be shaken, so that the surface of the cleaning plate will not adsorb a large amount of paper scraps, avoiding the friction between the residual paper scraps on the inner wall of the cleaning plate and the surface of the knife belt, and improving the stability of the knife belt.
