Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of suction devices, in particular to a composite clamp for dismantling, stacking and breaking woven bags. Background Art
[0002] In the industrial production process, woven bags are used as raw material packaging materials. Due to their heavy weight and high labor intensity, they are handled mechanically. Traditional clamping fixtures can be used for stacking but not for destacking. Therefore, they are improved to suction cup gripping. When the suction cup gripping is used for destacking, the surface of the woven bag may be tilted and uneven, resulting in the suction cup being unable to establish a vacuum with the woven bag. When the suction cup absorbs the woven bag at the bag breaking station, the bag breaking mechanism will destroy the vacuum state of the suction cup, causing the woven bag to fall, and the material is difficult to discharge after the woven bag is broken. Therefore, we have made improvements on this and proposed a composite clamp for destacking and breaking woven bags. Utility Model Content

Corresponding holes 45 are opened on the baffle plate 44 corresponding to the hook claw 42, so that the hook claw 42 can be inserted into the woven bag after passing through the hole groove 45. When the hook claw 42 is separated from the woven bag, the baffle plate 44 is used to resist the woven bag, thereby realizing the separation of the hook claw 42 from the woven bag.
[0036] A limiting groove 46 is also installed on the base plate 1 corresponding to the hook claw 42 , and the transmission shaft 41 drives the hook claw 42 to be inserted into the limiting groove 46 to prevent the hook claw 42 from continuing to rotate, so that the hook claw 42 is located between the baffle 44 and the base plate 1 .

[0041] The working principle of the utility model is as follows: when grabbing materials, the cavity-type suction cup 2 draws negative pressure through the negative pressure port, so that the cavity is filled with negative pressure, and the suction force is large to absorb the woven bag materials, which is not easy to damage the materials, and solves the problem of destacking. Due to the accumulation of materials, the surface of the materials will be tilted. The universal joint 10 is used to adjust the angle of the substrate 1 so that the suction cup fits on the surface of the woven bag, making it easier to establish a vacuum environment. At the same time, the buffer flange plate 32 is elastically installed at the lower end of the connecting flange plate 31, and a buffer protection structure is adopted. During the pressing process of the robot hand, the materials and the suction cup are effectively protected to avoid damage to the materials and the clamp.

The shaking cylinders 38 on both sides of the buffer flange plate 32 act at intervals to control the substrate 1 to rotate back and forth along the universal joint 10 through the push block 39, so as to achieve the shaking of the woven bag and shake out the residual materials in the woven bag. The device adopts a cavity-type suction cup 2 in conjunction with a hook claw 42 design, so that the woven bags can be stably grasped during the process of unstacking and breaking the woven bags, so that the woven bags can be quickly drained of materials, thereby improving work efficiency.
