Abstract
A vertically movable foam sponge cutting apparatus includes a vertical cutting device disposed on a blade strip frame. The vertical cutting device can be moved left and right in a vertical state. In addition, the vertical cutting device includes an ascending/descending device which is controllably movable up and down to change the rigidity of the blade strip in a cutting operation area. A foam sponge is cut along vertical cutting lines on a working bench. Therefore, a greater cutting function is achieved and the power consumption is lowered.
Claims1
A vertically movable foam sponge cutting apparatus comprising an apparatus body having a front face, a blade strip frame including upper and lower beams, a blade strip, a guide wheel unit and a blade turning unit wherein:
- a working bench is mounted on said front face of said apparatus body;
- said blade strip frame bridged over said apparatus body and a blade turning unit movement control mechanism disposed between said upper and said lower beams;
- said blade turning unit including upper and lower blade seats each of which has a seat body, transmission mechanism and blade holder;
- and
- said guide wheel unit including a driving wheel and multiple wheels disposed on said upper beam of said blade strip frame and said two seat bodies of said blade turning unit fixing said blade strip for cutting operation, and a pulley disposed on each of said seat bodies and said blade strip wound on said guide wheel unit and pulled and conducted to form a close winding line with a fixed length including a vertical working section of the blade strip, said foam cutting apparatus being characterized in that an ascending/descending device is disposed between said upper and lower beams of said blade strip frame and associated with said blade turning unit movement control mechanism for changing the interval of the working section of said blade strip;
- and wherein said ascending/descending device includes a linear slide bar seat fitted on a driving mechanism, a slide bar seat being connected with the blade turning unit movement control mechanism, whereby the blade seat hung on the slide bar seat can be ascended or descended along with the slide bar seat and wherein said ascending/descending device includes a pair of internally threaded elements and a pair of guide threaded rods extending through said internally threaded elements, and a motor for synchronously driving said guide threaded rods to thereby change the interval of the working section of the blade strip.
