A, described carrier roller frame are provided with air intake house steward, air intake house steward is provided with volume damper and one group of air intake arm, air intake arm is respectively equipped with magnetic valve, the other end of magnetic valve is respectively equipped with tuyere, tuyere is arranged in order along the running orbit of transverse cutting unit cutting knife, and the upper plane of tuyere is lower than the upper plane of carrying roller;
Position b, described transverse cutting unit crossbeam corresponding to tuyere is respectively equipped with one group of touch switch, and touch switch controls the magnetic valve of corresponding tuyere lower end respectively, and the Cutter apron of transverse cutting unit is provided with contact, and when cutting knife moves, contact coordinates with touch switch respectively;
Be provided with communicating pipe on the downside of c, described carrier roller frame, be provided with variable valve and one group of blast pipe communicating pipe, blast pipe be respectively equipped with one group of air outlet, the import of variable valve is connected with the air intake house steward of volume damper entrance end;
Intersection regions on the upside of d, described carrier roller frame is respectively equipped with wind outlet panel along the both sides of tuyere, wind outlet panel is respectively equipped with and organizes air outlet opening more, and the upper plane of wind outlet panel is lower than the upper plane of carrying roller;
Correspond to often group air outlet opening below e, described wind outlet panel and be respectively equipped with out air compartment, go out the suitable for reading of air compartment and be connected with wind outlet panel respectively, go out air compartment and be communicated with air outlet opening, the end opening going out air compartment connects with corresponding air outlet respectively;
One group of described tuyere is suitable for reading is rectangle, and the minor face of adjacent tuyere connects respectively, and the long limit of tuyere both sides is connected with the wind outlet panel of both sides respectively.
Described going out between air compartment is respectively equipped with back up pad, and the upper end of back up pad is connected with wind outlet panel, and the lower end of back up pad is connected on blast pipe.
Owing to have employed technique scheme, transverse cutting unit is when cutting ultra thin plate glass belt, in the intersection regions of cutting machine, by air outlet opening high-pressure blast jacking plate glass belt, plate glass belt is made to swim in wind outlet panel, eliminate drawback unsettled between adjacent carrying roller height point, resist cutter head to the downward pressure of plate glass belt by tuyere high-pressure blast, avoid plate glass belt by the phenomenon of pressure break.
In order to more detailed explanation the present invention, followingly accompanying drawings provide a most preferred embodiment.
Accompanying drawing illustrates:

Embodiment:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of strength jacking device for ultra-thin flat glass crosscut, it comprises: the carrying roller 5 that the carrier roller frame 6 below transverse cutting unit 1, transverse cutting unit, carrier roller frame are arranged, is characterized in that:
A, described carrier roller frame are provided with air intake house steward 11, air intake house steward is provided with volume damper 10 and one group of air intake arm 9, air intake arm is respectively equipped with magnetic valve 12, the other end of magnetic valve is respectively equipped with tuyere 8, tuyere 8 is arranged in order along the running orbit of transverse cutting unit cutting knife, tuyere 8 is suitable for reading is rectangle, and the minor face of adjacent tuyere connects respectively, and the upper plane of tuyere is lower than the upper plane of carrying roller 5;
Position b, described transverse cutting unit 1 crossbeam corresponding to tuyere 8 is respectively equipped with one group of touch switch 13, touch switch controls the magnetic valve 12 of corresponding tuyere lower end respectively, the Cutter apron of transverse cutting unit is provided with contact 14, and when cutting knife moves, contact coordinates with touch switch 13 respectively;
Be provided with communicating pipe 16 on the downside of c, described carrier roller frame 6, be provided with variable valve 17 and one group of blast pipe 15 communicating pipe, blast pipe 15 be respectively equipped with one group of air outlet 18, the import of variable valve 17 is connected with the air intake house steward 11 of volume damper 10 entrance end;
Intersection regions on the upside of d, described carrier roller frame 6 is respectively equipped with wind outlet panel 2 along the both sides of tuyere 8, the long limit of tuyere both sides is connected with wind outlet panel 2 respectively, wind outlet panel 2 is respectively equipped with many group air outlet openings 3, the upper plane of wind outlet panel 2 is lower than the upper plane of carrying roller 5;
E, described wind outlet panel 2 correspond to often group air outlet opening 3 below and are respectively equipped with out air compartment 7, go out the suitable for reading of air compartment 7 to be connected with wind outlet panel 2 respectively, go out air compartment 7 to be communicated with air outlet opening 3, the end opening going out air compartment 7 connects with corresponding air outlet 18 respectively, go out between air compartment 7 and be respectively equipped with back up pad 4, the upper end of back up pad 4 is connected with wind outlet panel 2, and the lower end of back up pad 4 is connected on blast pipe (15).
Owing to have employed technique scheme, when plate glass belt is by intersection regions, high-pressure blast is emerged by the air outlet opening in wind outlet panel, air casing is formed between wind outlet panel and plate glass belt, plate glass belt swims in wind outlet panel, eliminate the unsettled region between the adjacent carrying roller height point in intersection regions, when cutting machine runs, cutting knife moves to corresponding position, contact conducting touch switch Controlling solenoid valve on Cutter apron is opened, corresponding tuyere ejection high-pressure blast upwards jacking cutter head to the downward pressure of plate glass belt, by the size regulating the volume damper that intake stack is arranged can control jacking force, avoid plate glass belt by the phenomenon of pressure break.
