[0003] For example, the Chinese patent with the publication number CN214924833U discloses a practical slotting machine for extruded boards, including a base, a slot body is provided at the upper end of the base, a limiting mechanism is provided in the slot body, two device plates are fixedly connected to the upper end of the base, a mounting plate is fixedly connected to the upper end of the device plate, a device frame is fixedly connected to the upper end of the mounting plate, a lifting mechanism is provided at the upper end of the device frame, a mounting groove is provided on the side wall of the device plate, a slider is provided in the mounting groove, the slider is slidably connected to the inner wall of the mounting groove, a rotating mechanism is provided between the two sliders, and the rotating mechanism is connected to two sleeve rings. The utility model has a reasonable structure, and the feeding depth of the slotting knife can be adjusted, which is convenient for slotting of different depths. By setting a fixing mechanism, it is convenient to adjust the spacing between the slotting knives, which is convenient for slotting of different spacings; it is convenient to limit the extruded boards of different widths, which is conducive to improving the accuracy of slotting.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: the height of the cutters in the same row cannot be adjusted at will when the device is in use. When the cutters are damaged, the cutting depth will become shallower. At this time, the height of the cutters needs to be adjusted in time to avoid different cutting depths of the cutters in the same row. At the same time, the cutters may be damaged after long-term use. The damaged blades may not be able to maintain a stable cutting depth and accuracy during the cutting process, resulting in uneven and inconsistent notches, and even possible uncut or off-cut situations. This will seriously affect the quality and appearance of the product. In view of this, we propose a slotting machine for extruded boards. Utility Model Content
