The direction of the upper surface of the table 49 of the belt 31 is consistent (for example, from left to right), and when the sheet comes in this direction, the linear speed of the adjusting belt 31 is consistent with the speed of the sheet, so that the belt 31 and the sheet are relatively static and no friction phenomenon occurs. The same belt 31 is adopted for transportation, the speeds of the belts on the two sides of the cutting gap 27 are always consistent, and the phenomenon of asynchronism cannot occur. The two driving rollers drive the belt 31 at the same time, and the driving positions are almost positioned at the positions of equal length of the belt, so that the stress is uniform, the service life of the belt is prolonged, and the vibration of the belt caused by uneven stress is reduced.

As shown in fig. 18, the present embodiment uses the synchronizing gear 53, but is not limited to this, and it can be realized by adjusting the wrapping direction of the belt only, for example, a synchronizing pulley, and the two drive rolls can be synchronously rotated by changing one of the two wraps of the first drive roll 30 and the second drive roll 65 into the reverse wrap of the shape of the figure.

Movement of the cutting gap 27.

As shown in fig. 3, the upper moving beam 15 is capable of reciprocating in the direction of the guide rail 6, driven by the upper moving beam servomotor 24, the upper moving beam reducer 22, and the gear 42 mounted thereon; the plate on the belt 31 is static relative to the belt 31, the upper beam left driven roller 45 and the upper beam right driven roller 51 move in a reciprocating mode along with the upper moving beam 15, and the length of the belt 31 is not changed when the upper moving beam 15 moves in a reciprocating mode, so that the movement of the moving beam 15 is relatively independent of the movement of the belt 31; the cutting gap 27 is also mounted on the upper moving beam 15, also following the reciprocating movement of the upper moving beam 15. The load of the upper moving beam 15 is only the upper beam left driven roller 45 and the upper beam right driven roller 51, the load is relatively small, the use function is not reduced, in addition, when the following work is carried out, only the belt at the cutting gap 27 is separated from the plate material downwards or contacts the plate material upwards, other positions also keep the original state, the large-area shaking of the plate material can not be caused, and the influence on the cutting quality is reduced.

The movement of the lower moving beam 54.

As shown in fig. 3, the lower moving beam 54 is installed in the same manner as the driving manner, and the lower moving beam 54 is controlled to move in the opposite direction while the upper moving beam moves 15, so that the parameters such as acceleration, velocity and displacement are maintained to be the same, but the directions are opposite, which is easily realized in the servo control. As shown in fig. 3, the belt inner ring 70 of the belt 31 is wrapped around the pair of first lower beam driven rollers 59 and the first driving roller 30 to form a zigzag wrapping, so that the wrap angle of the belt 31 is increased, and the belt 31 is driven by the first driving roller 30 to rotate; the motion characteristic of the belt 31 transmission shows that the rotation of the belt 31 is completely driven by the drive roll, the drive roll servo motor 52 controls the drive roll to rotate, the belt 31 rotates along with the drive roll servo motor 52 controls the drive roll to stop, and the belt 31 also stops, so that the belt inner ring 70 and the first drive roll 30 are connected together by the zigzag wrapping structure, and the first drive roll 30 moves along with the lower moving beam 54, so that the belt inner ring 70 can be moved by the lower moving beam 54. The belt outer ring 71 and the belt inner ring 70 have the same structure of being wrapped in a zigzag manner at the driving roll, and the belt outer ring 71 also synchronously moves along with the lower moving cross beam 54.

As can be seen from the movement of the cutting gap 27 and the movement of the lower moving beam 54, as shown in fig. 3, assuming that the upper moving beam 15 moves leftward by S distance, the lower moving beam 54 moves rightward by S distance with the same parameter, and the inner belt ring 70 and the outer belt ring 71 surrounded by the upper beam left driven roller 45 each move by S distance; meanwhile, the lower moving beam 54 drives the belt inner ring 70 and the belt outer ring 71 to synchronously move rightwards by the distance of S; the belt inner ring 70 and the belt outer ring 71 which are wrapped by the upper beam right driven roller 51 move to the left by the distance S respectively, and similarly, when moving to the right, the belt inner ring and the belt outer ring operate in the opposite manner. The lower moving beam 54 is additionally arranged to synchronously drag the belt inner ring 70 and the belt outer ring 71 to move, and the problem that the belt 31 cannot be controlled synchronously, vibrating and changing speed due to the fact that the belt 31 is stressed unevenly due to the difference between the inner ring and the outer ring when the cutting gap 27 and the belt 31 move synchronously is solved.

The first driving roller 30 and the second driving roller 65 are disposed on the lower moving beam 54, and do not affect the rotation of the belt 31 when the belt 31 is moved by the upper moving beam 15 and the lower moving beam 54.

As shown in fig. 3, if other fixed driven rollers are replaced by driving rollers, the rotation of the belt 31 can be driven, but when the belt 31 moves under the driving of the upper moving beam 15 and the lower moving beam 54, the rotation speed of the belt 31 can be overlapped with the driving speed of the upper moving beam 15 and the lower moving beam 54, and the movement of the belt 31 is not controlled by the driving rollers, which can cause additional friction, sudden and slow, and other adverse factors, so that the driving rollers are arranged on the lower moving beam 54, the lower moving beam 54 drives the driving rollers to move, the rotation speed of the belt 31 is not overlapped with the moving speeds of the upper moving beam 15 and the lower moving beam 54, the rotation of the belt 31 is completely controlled by the driving rollers, which can not generate additional adverse factors, meet the requirements during cutting, and improve the cutting quality.

And (5) carrying out a laser cutting synchronous process.

As shown in fig. 3, during laser cutting, the movement speed of the plate is the same as the transportation speed of the belt 31, and the plate can be transported uninterruptedly, the upper moving beam 15 drives the cutting gap 27 to be the same as the cutting head 50 to move in the plate moving direction, so that when cutting is performed, the cutting gap 27 is always below the cutting head 50, smoke dust and waste residue can always fall into the cutting gap 27, and finally, the smoke dust and waste residue are collected in the waste residue box 43 in a centralized manner. In order to collect smoke and dust and prevent waste slag from splashing, the waste slag box 43 is provided with a dust collector connector 12 connected with a negative pressure dust collector, so that the lower part of the cutting area is always in a negative pressure state, and the smoke and dust and the waste slag are convenient to collect.
