The inner wall of the fixing groove 909 is rotatably connected with a positive and negative threaded rod 902. One end of the positive and negative threaded rod 902 is fixedly connected with a turning handle 903 extending to the outside of the fixing plate 2. Both sides of the surface of the positive and negative threaded rod 902 are threadedly connected with thread blocks 905. The front side of the thread block 905 is fixedly connected to the back side of the pneumatic telescopic rod 3. By rotating the turning handle 903, the positive and negative threaded rod 902 is driven to rotate, so that the thread block 905 slides and drives the pneumatic telescopic rod 3 to slide, thereby changing the spacing between the suction cups 6, so that it can meet the feeding action of conveyor belts of different widths, thereby improving its applicability.

[0030] In this embodiment, scale values ​​904 are opened on the upper ends of both sides of the front side of the fixed plate 2, and the scale values ​​904 are symmetrically distributed about the vertical center axis of the fixed plate 2. The symmetrically distributed scale values ​​904 allow the staff to clearly know the sliding position of the pneumatic telescopic rod 3, which is convenient for accurately adjusting the position of the suction cup 6.

[0031] In this embodiment, a card slot 907 is provided at the upper and lower ends of one side of the fixed plate 2, and a card block 906 is movably connected inside the card slot 907. A protective cover 901 is fixedly connected to one side of the card block 906.

[0036] In this embodiment, a snap-fit ​​structure is formed between one side of the sealing plate 703 and the interior of the mounting groove 706. The cross-sectional area of ​​one side of the sealing plate 703 is larger than the cross-sectional area of ​​the mounting groove 706. By using a sealing plate 703 with a larger area, the sealing plate 703 can completely block and seal one side of the mounting groove 706 after snapping.

After the adjustment is completed, the sliding engagement of the card block 906 and the inside of the card slot 907 is used to realize the sliding engagement of the protective cover 901 to shield and protect the turning handle 903, so as to avoid the turning handle 903 from accidentally colliding and rotating when the sliding seat 1 slides to feed;

[0039] Then, the sliding seat 1 and the guide rail 5 are used to slide and drive the fixed plate 2 to slide to a suitable position, and then the pneumatic telescopic rod 3 is started to make the connecting seat 8 descend and drive the suction cup 6 to be close to the top of the sheet material, and then the negative pressure device is used to generate negative pressure inside the filter box 12, and then the suction force is generated by the suction cup 6 to suck the sheet material, and then the pneumatic telescopic rod 3 is started to make the sheet material rise, and then the sliding seat 1 and the guide rail 5 are used to make the sheet material slide to the top of the conveyor belt, and then the pneumatic telescopic rod 3 is started to make the sheet material descend to a suitable position, and then the negative pressure device is closed so that there is no suction at the suction cup 6, so that the double-station feeding of the sheet material is realized, and the feeding efficiency is improved;

[0040] At the same time, in the process of absorbing the sheet material, the air sucked into the filter box 12 can be filtered through the filter screen 702 to prevent external dust and other impurities from being sucked into the negative pressure equipment and causing inconvenience in its operation, thereby achieving its filtering and adsorption. When not in use, the fixing bolt 704 can be rotated by a tool to completely disengage from the bolt hole 701, and then the filter screen 702 can be removed from the filter box 12 through the sealing plate 703, so as to facilitate the thorough cleaning and anti-blocking of the filter screen 702. During installation, the sealing ring 705 can be used to improve the sealing performance of the sealing plate 703 and the internal engagement installation of the mounting groove 706.
