When the width of the base paper or the base paper is smaller than that of the corrugating roller body 11, and the width of the base paper or the bottom paper can cover the notch of the partial adjusting groove 9 on the vacuum adjusting tube 7, the driving gear 2 drives the driven gear 1 to rotate. The vacuum amount adjusting tube 7 is rotated in the vacuuming hole 6, and the rotation direction of the vacuum amount adjusting tube 抽 in the vacuuming hole 6 is in the oblique direction state along the adjusting groove 9, so that when the vacuum amount adjusting tube 7 is rotated, adjacent to the first The notch of the adjusting groove 9 of the adjusting end 8 is first rotated to a corresponding angle, and the vacuum adjusting pipe corresponding to the other surface of the adjusting groove 9 is first blocked. The ends of the corrugated roller body 11 are not covered by the base paper or the bottom paper. The air duct 5, and the slot of the adjusting slot 9 overlapping with the base paper or the bottom paper is adjacent to the corresponding air duct 5, and the slot of the corresponding adjusting slot 9 communicates with the air channel 5, at this time, due to the adjusting slot 9 and The correspondence relationship between the air ducts 5 and the vacuum pumping by the suction fan does not affect the vacuuming process of the wind tunnel 5 covered by the base paper or the bottom paper.

When the width of the base paper or the base paper is smaller than the length of the corrugating roller body 11, and the base paper or the bottom paper does not overlap with the second regulating end 10 of the adjusting groove 9, the wind groove corresponding to the length of the notch of the adjusting groove 9 is required. 5 All should be blocked. During the adjustment, the driving gear 2 drives the driven gear 1 to rotate, so that the vacuum adjusting tube 7 rotates in the vacuuming hole 6 until the notch of the adjusting groove 9 is away from the wind groove 5, that is, the notch of the adjusting groove 9 is adjacent to the corrugating roller body. The center of the vacuum regulating tube Ί corresponding to the other surface of the adjusting groove 9 can block the communication between the corresponding air channel 5 and the vacuuming hole 6; at this time, when the suction fan is evacuated through the vacuuming hole 6, The air groove 5 blocked by the vacuum amount adjusting tube 7 does not leak, and the air groove 5 at the center of the corrugating roller body 11 is evacuated through the vacuuming hole 6 and the air venting hole 12. Since the width of the base paper or the base paper is in contact with the wind groove 5 at the center of the corrugating roller body 11, it is only necessary to install the switch shaft mechanism 4 at both ends of the corrugating roller body 11. After the adjustment of the vacuum amount adjusting tube 7 is completed, since the driving gear 2 and the driven gear 1 are kept relatively stationary, the processing of the corrugating roller body 11 is not affected.

The corrugated roller body 11 of the present invention is provided with a plurality of uniformly distributed vacuuming holes 6 through which the vacuuming holes 6 are passed. The vacuuming holes 6 are provided with a switching shaft mechanism composed of a vacuum adjusting tube 7 and a driven gear 1. 4; The vacuum adjusting tube 7 is provided with an adjusting groove 9, and the adjusting groove 9 and the outer wall of the vacuum adjusting tube 7 form a first adjusting end 8 and a second adjusting end 10, and the first adjusting end 8 and the second adjusting end The end 10 allows the adjustment groove 9 to be distributed obliquely on the vacuum regulating tube 7, so that when the vacuum adjusting tube is rotated in the vacuuming hole 6, it can be adapted to block different wind grooves 5, and adapt to the width requirements of different processing.
