[0003] There are many types of gripping devices. As for the gripping of paper, since the paper is thin, it is impossible to grip it by clamping. However, if the raw paper is too heavy, it is easy to fall off by adhesion, resulting in unstable gripping of the paper. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an automatic raw paper grabbing device, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: comprising: a supporting frame plate, an adjusting push rod mounted on the surface, a moving frame plate slidably mounted at the front end of the supporting frame plate, and a downward pressing push rod longitudinally inserted inside the moving frame plate.

[0006] Also includes:

[0007] The downward pressure adsorption plate is installed below the movable frame plate, and an adjustment groove is provided on the surface of the downward pressure adsorption plate, and an expansion arm is slidably installed in the groove of the adjustment groove;

[0008] The adsorption holes are provided at the bottom of the downward-pressed adsorption plate, and the bottom of the extension arm is provided with adsorption openings distributed at intervals;

[0009] The wind force transmission bin is fixedly arranged on the top of the downward pressure adsorption plate, and the top of the wind force transmission bin is connected with the adsorption fan bin through the connecting main pipe.

[0010] Furthermore, a protrusion is arranged on the top of the movable frame plate, and a collar sleeved on the outside of the protrusion is arranged on the output end of the adjusting push rod.

[0011] Furthermore, the downward pressure adsorption disk is in a disk shape, and the adsorption holes are distributed in a circular array along the bottom of the downward pressure adsorption disk.

[0012] Furthermore, a groove is provided on the inner wall of the adjusting groove, and a sliding block extending into the groove is provided on the side wall of the extension arm.

[0013] Furthermore, an adjusting screw is installed on one side of the extension arm, and a cavity that allows the adjusting screw to rotate freely is provided in the cavity of the downward pressure adsorption plate.

[0014] Furthermore, an outer meshing sleeve of the adjusting screw rod is provided with an meshing moving block, a support rod is provided on the side wall of the meshing moving block, and the support rod passes outward from a groove on one side and is connected to the expansion arm.

[0015] Furthermore, the wind transmission bin is connected to the extension arm via an adsorption connecting pipe, and a channel communicating with the adsorption hole is provided in the cavity of the wind transmission bin.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The present application utilizes a disc-shaped downward-pressed adsorption plate to be close to the surface of the paper, and generates suction at the adsorption holes through the connection of the adsorption fan bin and the connecting main pipe. In this way, after the adsorption holes are in contact with the paper, the evenly distributed adsorption holes can adsorb the paper, thereby completing the paper grabbing. In order to accommodate papers of different sizes, the expansion arm retained in the adjustment groove can be pulled outward, so that the adsorption opening at the bottom of the expansion arm can be used to adsorb papers at farther positions, thereby improving the application range of the entire device, and having the characteristics of stable adsorption and convenient use.
