Detailed Description

The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and functions of the present invention, but the present invention is not limited thereto.

As shown in fig. 1 and 2, the utility model provides a pair of automatic pocket inserting machine's bag lifting mechanism comprises removal slip table 1, mount pad 3, swinging boom 5, lifting control device and sucking disc subassembly etc. removes slip table 1 and fixes on the motor bracket of pocket inserting machine, and the side of removing slip table 1 is provided with drive arrangement, if drive actuating cylinder, motor. The upper end face of the movable sliding table 1 is provided with a sliding rail, a sliding block 2 in sliding fit is arranged on the sliding rail, the lower end of the sliding block 2 is fixedly connected with a piston rod of a driving cylinder, and the piston rod moves in the movable sliding table 1 in a telescopic mode. When the driving device is a motor, the linear motion of the sliding block 2 on the sliding rail is realized by adopting a structure of the screw rod sliding block 2. The upper end face of the sliding block 2 is fixed with a mounting seat 3, a revolute pair is arranged on the mounting seat 3, and the speed reduction motor 4 is connected with the lower end of the rotating arm 5 through the revolute pair, so that the rotating arm 5 rotates around an X axis.
