The described The clamping arm frame 5 is in sliding fit with the first guide rail 2 . In traditional products, the first guide rail 2 and the second guide rail 3 are set, the second guide rail 3 and the paper taking platform 4 are movably assembled, and the first guide rail 2 and the mechanical claw, that is, the clamping arm frame 5, are movably assembled, which are generally chain-type sliders. The matching structure with the guide rail can realize the relative horizontal movement of the paper taking platform 4 and the clamping arm frame 5 . The movement of the reclaiming platform in the vertical direction is realized by the rotation of the screw, which is a mature technical means, and will not be elaborated and limited here.

The clamping arm claw 6 includes a connecting plate 7, a base 8, a left vertical plate 9, a right vertical plate 10, an upper clamping plate 11 and a lower clamping plate 12;

The left vertical plate 9 and the right vertical plate 10 are provided with sliding rails 13, and the front movable surface for the upper clamping plate 11 to slide and the sliding rail for the base 8 are formed between the left vertical plate 9 and the right vertical plate 10. back active surface. The front movable surface and the rear movable surface are two opposite virtual planes. The setting of the two surfaces is to rationally utilize the space so that the movable trajectories of the upper splint 11 and the base 8 do not interfere with each other.

The upper clamping plate 11 and the base 8 are provided with a sliding portion 14 corresponding to the size and shape of the sliding rail 13 , and the sliding portion 14 and the sliding rail 13 are slidably matched. Here, the two are defined as sliding fit, and the pneumatic structure of the cylinder realizes intelligent control.

The connecting plate 7 is fixedly assembled with the top of the left vertical plate 9 and the right vertical plate 10 respectively, and the lower clamping plate 12 is fixedly assembled with the bottom of the left vertical plate 9 and the right vertical plate 10 respectively. The connecting plate 7 connects and fixes the tops of the left vertical plate 9 and the right vertical plate 10, and the lower clamping plate 12 connects and fixes the bottoms of the left vertical plate 9 and the right vertical plate 10, so as to realize a relatively stable frame.

The upper splint 11 is of an L-shaped structure, and a front lift cylinder 15 is arranged between the upper splint 11 and the connecting plate 7, and the upper splint 11 passes through the front lift cylinder 15 and takes the connecting plate 7 as a static reference system straight line. displacement. The characteristic of the L-shaped structure is that one end of the upper clamp plate 11 is provided with a sliding portion 14 to slide along the front movable surface, and the other vertical end of the upper clamp plate 11 forms a clamping range with the lower clamp plate 12, or the opposite surface for clamping. . The up-and-down movement of the upper clamping plate 11 is controlled by the front lifting cylinder 15, and at this time, the connecting plate 7 and the lower clamping plate 12 are relatively stationary.

The lower clamping plate 12 is provided with a rear lifting cylinder 16, and the lower clamping plate 12 is linearly displaced by the rear lifting cylinder 16 with the base 8 as a stationary reference frame. The rear lift cylinder 16 drives the lower clamping plate 12 and almost the entire clamping arm claw 6 except the base 8 to move up and down. Because the base 8 and the clamping arm frame 5 are movably assembled, the base 8 cannot move up and down.

The clipping arm claw 6 is fixedly assembled with the clipping arm frame 5 through the base 8, and the base 8 and the clipping arm frame 5 can be screwed together, which will not be elaborated and limited here.

The sliding rail 13 is in the shape of a bar. The sliding rail 13 is arranged on the opposite sides of the left vertical plate 9 or the right vertical plate 10. The sliding portion 14 is provided with a sliding groove 17. The chute 17 is a concave-shaped open structure, and the two opposite inner side walls of the chute 17 are provided with card slots 18 , the left vertical plate 9 or the right vertical plate 10 The card slot 18 and the slide rail 13 are locked in position, and the card slot 18 and the slide rail 13 are slidably matched in the length direction of the slide rail 13 . The clamping limit direction is perpendicular to the sliding direction, which is convenient for installation and use.

The lower clamping plate 12 has a stepped structure, and the stepped structure forms a certain barrier to the paper.

The connecting plate 7 is of a split structure, and the connecting plate 7 is assembled and fixed by screw connection, and the split structure is convenient for production and installation.

The connecting plate 7 includes a horizontal plate 19, a left connecting block 20 and a right connecting block 21. The two ends of the horizontal plate 19 are respectively connected to the left connecting block 20 and the right connecting block 21, and the direction of the length of the horizontal plate 19 is respectively the same as that of the left connecting block 20 and the right connecting block 21. The direction of the length of the left connecting block 20 or the right connecting block 21 is vertical. The front lift cylinder 15 and the rear lift cylinder 16 are in different positions in the horizontal direction, and the directions of the cylinder output shafts are the same, without interfering with each other, rational use of space, and no obstruction to the rear lift cylinder 16 .

The paper picking platform 4 is provided with a separating roller 22 on one side, the paper picking platform 4 moves, and the paper slides onto the paper picking platform 4 along the separating roller 22 .

Workflow overview: The paper picking platform 4 moves to the paper stack, and the paper moves to the paper picking platform 4 along the part of the separating roller 22, and this part is slightly tilted. The clamping arm frame 5 drives the clamping arm to move, the lower clamping plate 12 is inserted into the bottom of the paper, and the front lifting cylinder 15 acts to press down the upper clamping plate 11 to clamp the paper. Then, the clamping arm frame 5 drives the paper to completely move to the paper taking platform 4 . The paper pick-up platform 4 is adjusted to move up and down, left and right, and is docked with the next operation platform. At the same time, the upper clamping plate 11 is reset, and the clamping arm is moved out of the paper position. Next, the lower clamping plate 12 moves upward (including the clamping arm except for the base 8) to the top of the paper, and then to the other side of the paper, and the side of the base 8 assists the paper to move to the next operating platform. In this way, the transport of the paper is completed, ensuring the accuracy and efficiency of the process. The clamping arm clamp not only plays the role of clamping, but also has functions such as boosting and positioning.

Beneficial effects of the utility model: the paper pick-up arm provided by the utility model has an ingenious structure design, is convenient for production and installation, has precise positioning during paper clamping and transportation, and is transported from multiple angles of action, with diverse functions and practicability. and economical.
