Example

[0031] The bottom of the cutting table 1 is also provided with a second moving mechanism for the cutting knife 2 and the longitudinal rectangular frame 16 to move in opposite directions.

[0032] The first moving mechanism includes a U-shaped bracket 4, which is fixed to the bottom of the cutting table 1. A driving motor 5 is fixed to one end of the U-shaped bracket 4 by bolts. A longitudinal threaded rod 8 is fixed to the output end of the driving motor 5. The outer side of the longitudinal threaded rod 8 is threadedly connected to a longitudinal moving block 6. The interior of the longitudinal moving block 6 is slidably connected to a vertical lifting seat 7. The top of the vertical lifting seat 7 is fixedly connected to the cutting knife 2.

[0033] A longitudinal light rod 9 is fixed inside the U-shaped bracket 4. The longitudinal light rod 9 passes through the interior of the longitudinal moving block 6 and is slidably connected to the longitudinal moving block 6, so that the longitudinal moving block 6 can slide longitudinally on the outside of the longitudinal light rod 9. By setting the longitudinal light rod 9, the moving track of the longitudinal moving block 6 can be limited.

[0034] Vertical sliders are fixed on both sides of the vertical lifting seat 7. A vertical slide groove adapted to the vertical slider is provided inside the longitudinal moving block 6. The longitudinal moving block 6 and the vertical lifting seat 7 are slidably connected through the vertical slider and the vertical slide groove, so that the vertical lifting seat 7 can slide vertically inside the longitudinal moving block 6, and when the longitudinal moving block 6 moves, the vertical lifting seat 7 can move;

[0035] When the driving motor 5 is in operation, the longitudinal threaded rod 8 can rotate, and the rotation of the longitudinal threaded rod 8 enables the longitudinal moving block 6 to slide outside the longitudinal polished rod 9, and the movement of the longitudinal moving block 6 enables the vertical lifting seat 7 and the cutting knife 2 to slide, thereby enabling the cutting knife 2 to cut the cloth;

[0036] The second moving mechanism includes a lifting cylinder 15, which is fixed to one end of the U-shaped bracket 4, and a vertical connecting plate 14 is fixed to the output end of the lifting cylinder 15. The top and bottom of the vertical connecting plate 14 are rotatably connected to an oblique rotating column 13 through a pin shaft, and one end of the oblique rotating column 13 is rotatably connected to a vertical sliding tube 12, and the vertical sliding tube 12 is slidably connected to a vertical limiting rod 11 inside, one end of one of the vertical sliding tubes 12 is fixed to a longitudinal lifting rod 10, and one end of the other vertical sliding tube 12 is fixedly connected to a longitudinal rectangular frame 16;

[0037] The longitudinal lifting rod 10 passes through the interior of the vertical lifting seat 7 and is slidably connected with the vertical lifting seat 7. A circular through hole is provided inside the vertical lifting seat 7. The longitudinal lifting rod 10 is located inside the circular through hole and is slidably connected with the vertical lifting seat 7 through the circular through hole, so that when the longitudinal moving block 6 moves, the vertical lifting seat 7 can slide on the outside of the longitudinal lifting rod 10. When the longitudinal lifting rod 10 is raised or lowered, the vertical lifting seat 7 can be vertically raised or lowered inside the longitudinal moving block 6, thereby driving the cutting knife 2 to be raised or lowered;

Through the setting of the circular slide groove, the circular sliding piece 21 can slide vertically inside the first rotating member 18, and the sliding of the circular sliding piece 21 causes the spring 22 to be deformed by force;

[0040] The operation of the lifting cylinder 15 enables the vertical connecting plate 14 to move. The movement of the vertical connecting plate 14 enables the vertical sliding tube 12 to slide on the outside of the vertical limiting rod 11 through the oblique rotating column 13. The movement of the vertical sliding tube 12 enables the longitudinal lifting rod 10 to move vertically. The vertical movement of the longitudinal lifting rod 10 enables the vertical lifting seat 7 to move vertically inside the longitudinal moving block 6. When the cutting knife 2 rises to the surface of the cutting table 1, the cutting knife 2 can cut the cloth. The movement of the vertical sliding tube 12 enables the longitudinal rectangular frame 16 to move vertically. When the longitudinal rectangular frame 16 descends, the two smoothing rollers 3 can contact the ground. When the longitudinal rectangular frame 16 continues to descend, the rectangular rotating plate 17 can drive the smoothing roller 3 to rotate, so that the surface of the cloth is smoothed. In this process, the circular sliding sheet 21 slides inside the first rotating member 18, and the spring 22 is deformed under force.

[0041] Through the second moving mechanism, the cutting knife 2 can be moved to the surface of the cutting table 1, and the two smoothing rollers 3 can be moved while in contact with the cloth, so that the surface of the cloth is smoothed for subsequent cutting.

When the cutting knife 2 is located at the bottom of the cutting table 1, it can prevent workers from accidentally touching the cutting knife 2, thereby improving the safety of the production process.

[0042] When in use: the operation of the lifting cylinder 15 enables the vertical connecting plate 14 to move, and the movement of the vertical connecting plate 14 enables the vertical sliding tube 12 to slide on the outside of the vertical limiting rod 11 through the oblique rotating column 13, and the movement of the vertical sliding tube 12 enables the longitudinal lifting rod 10 to move vertically, and the vertical movement of the longitudinal lifting rod 10 enables the vertical lifting seat 7 to move vertically inside the longitudinal moving block 6, when the cutting knife 2 rises to the surface of the cutting table 1, the cutting knife 2 can cut the cloth, and the movement of the vertical sliding tube 12 enables the longitudinal rectangular frame 16 to move vertically, and when the longitudinal rectangular frame 16 descends, the two smoothing rollers 3 can contact the ground, and when the longitudinal rectangular frame 16 continues to descend, the rectangular rotating plate 17 can drive the smoothing roller 3 to rotate, so that the surface of the cloth is smoothed, and in this process, the circular sliding sheet 21 slides inside the first rotating member 18, and causes the spring 22 to deform under force;

[0043] When the driving motor 5 is operating, the longitudinal threaded rod 8 can rotate. The rotation of the longitudinal threaded rod 8 enables the longitudinal moving block 6 to slide on the outside of the longitudinal light rod 9. The movement of the longitudinal moving block 6 enables the vertical lifting seat 7 and the cutting knife 2 to slide, thereby enabling the cutting knife 2 to cut the cloth.
