In addition, the first carrying claw and the mounting frame are connected through the vertical sliding mechanism, so that the mounting frame and the second carrying claw can continue to move vertically downwards under the driving of the vertical driving mechanism, and when the second carrying claw moves to a position with a lower side face of the material bag, the vertical driving mechanism stops working.
Then, the transverse driving mechanism drives the carrying mechanism to do transverse movement, so that the second carrying claw is stabbed into the material bag, and the clamping claw in the second carrying claw is still elastically pressed on the upper surface of the material bag at the moment.

Referring to fig. 1-9, the working principle of the material mixing device of the present invention is:
during operation, the transverse driving mechanism 4 and the longitudinal driving mechanism 5 drive the carrying mechanism 2 to move above a material bag 6 to be carried, then the vertical driving mechanism 3 drives the carrying mechanism 2 to move vertically, so that a first carrying claw in the carrying mechanism 2 is in contact with the upper surface of the material bag 6, and a clamping claw 2-4 in the first carrying claw overcomes the elasticity of a torsion spring 2-7 to rotate towards a second carrying claw 2-2 under the action of acting force and reaction force in the process of contacting with the material bag 6. In addition, because the first carrying claw is connected with the mounting frame 2-1 through the vertical sliding mechanism 8, the mounting frame 2-1 and the second carrying claw 2-2 can continue to move vertically downwards under the driving of the vertical driving mechanism 3, and when the second carrying claw 2-2 moves to a position lower than the side surface of the material bag 6, the vertical driving mechanism 3 stops working (see figure 6).
Then, the transverse driving mechanism 4 drives the carrying mechanism 2 to make a transverse movement, so that the second carrying claw 2-2 pierces into the material bag 6, and at this time, the clamping claw 2-4 in the second carrying claw 2-2 still presses the upper surface of the material bag 6 elastically (see fig. 7). Then, the vertical driving mechanism 3 drives the mounting frame 2-1 and the second carrying claw 2-2 to vertically move upwards, and at the moment, the first carrying claw does not vertically move along with the second carrying claw 2-2 and the mounting frame 2-1 because the vertical sliding mechanism 8 is arranged between the second carrying claw 2-2 and the mounting frame 2-1. In the process that the vertical driving mechanism 3 drives the second carrying claw 2-2 to do vertical motion, the end part of the material bag 6, which is in contact with the second carrying claw 2-2, moves upwards, and the motion of the material bag 6 driven by the second carrying claw 2-2 can be divided into two partial motions, wherein one partial motion is vertical motion, and the direction is vertical upwards; the other partial motion is horizontal motion, and the direction is far away from the first carrying claw; due to the horizontal movement of the material pack 6, the material pack 6 is separated from the jaws 2-4 of the first jaw, and the jaws 2-4 of said first jaw are rotated away from the second jaw 2-2 by the torsion springs 2-7 to always abut against the upper surface of the material pack 6 (see fig. 8).
Subsequently, in the process that the vertical driving mechanism 3 drives the second carrying claw 2-2 to vertically move so as to drive the material bag 6 to move upwards, when the gravity of the material bag 6 is greater than the friction force between the material bag 6 and the second carrying claw 2-2, relative movement is generated between the material bag 6 and the second carrying claw 2-2, namely, the material bag 6 moves towards the direction far away from the second carrying claw 2-2 along the surface of the second carrying claw 2-2; this relative movement is divided into two partial movements, one of which is a vertical partial movement directed vertically downwards and the other is a horizontal partial movement directed horizontally towards the first transport jaw, so that, with the first transport jaw as a reference, the material pack 6 will be brought into contact with the gripper jaw 2-4 of the first transport jaw by this horizontal partial movement, so that the gripper jaw 2-4 penetrates the upper surface of the material pack 6, and with the continued horizontal partial movement of the pack, the gripper jaw 2-4 on the first transport jaw will be rotated away from the second transport jaw 2-2 by the action and the reaction, and when the gripper jaw 2-4 is brought into contact with the limiting element 2-8, the gripper jaw 2-4 will stop rotating, and at the same time the material pack 6 will also stop moving (neither horizontal partial movement, and does not make a vertical component movement), and then the vertical driving mechanism 3 continues to drive the mounting frame 2-1 and the second carrying claw 2-2 to move upward (see fig. 9). After vertical sliding mechanism 8 moved extreme position, first transport claw is along with mounting bracket 2-1 and second transport claw 2- -2 synchronous upward movement to carry material package 6 to the special position after, through horizontal actuating mechanism 4 and vertical actuating mechanism 5 coordination, thereby send material package 6 into mixer 7, stir material package 6 and the interior raw and other materials of material package 6 by mixer 7, and then accomplish whole compounding technology.

(2) the transverse driving mechanism 4 drives the carrying mechanism 2 to do transverse movement, so that the second carrying claw 2-2 is stabbed into the material bag 6;
(3) the vertical driving mechanism 3 drives the mounting frame 2-1 and the second carrying claw 2-2 to vertically move upwards, and the first carrying claw does not vertically move along with the first carrying claw within the sliding range of the vertical sliding mechanism 8;
(4) in the process that the vertical driving mechanism 3 drives the second carrying claw 2-2 to vertically move upwards, the end part of the material bag 6, which is in contact with the second carrying claw 2-2, moves upwards, and the clamping claw 2-4 in the first carrying claw rotates towards the direction far away from the second carrying claw 2-2 under the action of the torsion spring 2-7 and is always attached to the upper surface of the material bag 6; when the gravity of the material bag 6 is larger than the friction force between the material bag 6 and the second carrying claws 2-2, the material bag 6 moves along the surface of the second carrying claws 2-2 to a direction far away from the second carrying claws 2-2 and contacts with the clamping claws 2-4 in the first carrying claws, so that the clamping claws 2-4 are inserted into the material bag 6;
(5) after the vertical driving mechanism 3 drives the second carrying claw 2-2 to vertically move to the vertical sliding mechanism 8 to move to the extreme position, the first carrying claw and the second carrying claw 2-2 synchronously move upwards;
