[0017] The technical solution of the utility model is further described below through embodiments and in conjunction with the accompanying drawings.

[0018] Example:

[0019] This embodiment provides a sheet material suction mechanism, such as Figure 1 As shown, it includes a base plate 1, a telescopic rod 2, a first mounting plate 4, a second mounting plate 5 and a plurality of suction cups 6. The telescopic rod 2 is fixedly arranged on the base plate 1, and the movable end of the telescopic rod 2 is fixedly connected to the middle part of the first mounting plate 4. A sliding rod 3 is respectively arranged at both ends of the first mounting plate 4, and through holes matching the sliding rods are arranged at both ends of the base plate 1. The first mounting plate 4 is slidably connected to the base plate 1 through the sliding rods and the through holes. A first mounting groove 7 is arranged on the first mounting plate 4, and a plug hole is arranged in the middle part of the second mounting plate 5. A latch mechanism 9 passes through the plug hole and extends into the first mounting groove to fix the second mounting plate 5 to the first mounting plate 4. The distance between the two second mounting plates can be adjusted by adjusting the position of the latch mechanism in the first mounting groove. The second mounting plate 5 is provided with a second mounting groove 8, and the suction cup is arranged in the second mounting groove through a locking nut. The distance between the suction cups on the same side can be adjusted by changing the position of the suction cup on the second mounting groove.

[0020] like Figure 2 and Figure 3 As shown, the latch mechanism includes a sleeve 10, a rod 11 and a limiting bead 12. The upper end of the sleeve is provided with an opening for the rod to be inserted, the lower end is closed, and a limiting hole is provided on the side of the lower end for the limiting column to be exposed. The rod 11 is screwed into the sleeve 10 by threads, and the lower end of the rod is provided with a limiting bead extrusion portion 13, and the limiting bead extrusion portion is located between the limiting beads. In this embodiment, the limiting bead extrusion portion is in an inverted trapezoidal shape. In addition, a limiting block 13 is also provided on the side of the upper end of the sleeve, and a limiting groove matching the limiting block 13 is provided around the socket of the second mounting plate. A circle of first teeth is provided on the side of the sleeve, and second teeth matching the first teeth are provided on the inner wall of the first mounting groove. The first teeth mesh with the second teeth to achieve horizontal limitation of the latch mechanism and the first mounting groove.

[0021] When the sheet material suction mechanism in this embodiment needs to adjust the distance between the suction cups on the same side, the clamping fixation of the suction cup is released by loosening the locking nut, so that the suction cup can slide along the second mounting groove, and then the distance between the suction cups on the same side is adjusted; when the distance between the suction cups on different sides, that is, the distance between the two second mounting plates, is needed to adjust the distance, the rod body 11 is first turned to move the rod body upward, and the limiting bead extrusion part no longer squeezes the limiting bead, at this time the second mounting plate and the latch mechanism can be pulled out of the first mounting groove as a whole, and then the second mounting plate and the latch mechanism can be inserted into the appropriate position of the first mounting groove as a whole, and the rod body can be tightened again. After tightening the rod body, the limiting bead is partially extruded and abuts against the lower end surface of the first mounting groove, so that the latch mechanism cannot be pulled out, thereby realizing the fixation of the second mounting plate and the first mounting plate in the vertical direction. In addition, since the side wall of the sleeve is provided with a first tooth and the inner wall of the first mounting groove is provided with a second tooth, after the pin is inserted, the second mounting plate and the first mounting plate cannot rotate, thereby achieving horizontal fixation of the second mounting plate and the first mounting plate. Based on this, the angle of the suction cup on the same side can also be adjusted according to the shape of the sheet.

[0022] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
