the roller support is arranged on the locking frame through a positioning rotating shaft which is horizontally arranged, and the return spring piece is a torsion spring arranged on the positioning rotating shaft.
2. The multi-gate shearing device for plastic panels of air conditioner ceiling machines according to claim 1, wherein the rotary support assembly comprises a rotary flange rotatably mounted on the lower working table surface, and a horizontal rotary unit for driving the rotary flange to rotate in a horizontal plane, wherein the horizontal rotary unit comprises a rotary motor fixed on the lower working table surface, and a transmission worm connected with the rotary motor and horizontally arranged, and the side part of the rotary flange is matched with the transmission worm in a 'worm gear' structure.
3. The multi-gate shearing device for plastic panels of air conditioner ceiling machines according to claim 1, wherein said product jacking assembly comprises a plurality of product jacking cylinders mounted at the end angular position of the lower table surface and adapted to jack the lower surface of the upper table surface, said product jacking cylinders jacking stroke satisfying: when the product jacking air cylinder is reset, the product jacking air cylinder is not contacted with the upper working table surface, and when the product jacking air cylinder is jacked up to the highest, the plastic panel positioned on the upper working table surface can be adsorbed and fixed by the sucker piece which is moved in place and removed.
4. The multi-gate shearing device for plastic panels of air conditioner ceiling machines according to claim 1, wherein two sets of horizontal rotary positioning components are respectively arranged at the diagonal positions of the lower working table.
5. The multi-gate shearing apparatus for plastic panels of an air conditioner ceiling machine according to claim 1, wherein said suction cup member comprises a suction cup holder slidably fitted with the lower table surface, and a fixed suction cup mounted on the lower end surface of the suction cup holder for sucking the plastic panel.
6. The multi-gate shearing apparatus for plastic panels of an air conditioner ceiling tile as recited in claim 1, wherein said frame is further provided with a rail for laterally enclosing a shearing work area of the plastic panels.
