Problems solved by technology
[0002] The box clamping mechanism is an important part of the box stacking machine. Its function is to clamp the designated turnover box. After the lifting mechanism is activated, it cooperates with the supporting mechanism to stack the box to a certain height, so as to achieve the purpose of stacking the box. Now In the prior art, the clamping mechanism based on the cylinder has a small load-bearing capacity, the clamping weight is unstable, the end is expanded, and the error caused by the deformation of the turnover box cannot be eliminated.

Embodiment
[0024] The box clamping mechanism clamps the turnover box through four sets of clamping arm mechanisms. When the cylinder is retracted, the four sets of clamping arms are relatively inwardly swung through the connecting rods and rotating shafts on both sides and the clamping force is transmitted. When the cylinder is fully retracted, the clamping arm reaches the working position, and the lower jaw tongue is inserted into the turnover box. At this time, the spring is in a compressed state. When the turnover box has plastic deformation or elastic deformation due to materials, the jaw tongue can be compensated by the compression or elongation of the spring. When the cylinder is fully extended downwards, the jaw arms are opened to both sides, and the jaw tongue is separated from the turnover box. When stacking to the second layer, the upper jaw tongue provides auxiliary clamping, making the work more stable.

The invention discloses a box clamping mechanism based on cylinders. The box clamping mechanism based on the cylinders comprises an installing base, the cylinders, connecting bars, rotary shafts and clamping arms. The installing base is of an L-shape structure. The cylinders are fixedly installed in the installing base. The connecting bars are fixedly connected to the power output ends of the cylinders through inserting pins. The rotary shafts are perpendicularly and fixedly connected to the other ends of the connecting bars. Installing plates and the clamping arms are fixedly installed on therotary shafts through no-key shaft bushings. Clamping jaws are fixedly installed on the inner sides of the clamping arms. The box clamping mechanism based on the cylinders has the beneficial effectsthat the risks that boxes are not clamped, the boxes are not clamped tightly or the boxes are broken by clamping generated by deformation of circulation boxes can be eliminated, thus different workingconditions are met, and universality is high; and in the meantime, the boxes are clamped through the rotary shafts instead of rotation of certain supporting points, load bearing is large, and the tail end is stable.
Description
technical field [0001] The invention relates to the technical field of turnover box stacking, in particular to a box clamping mechanism based on an air cylinder. Background technique [0002] The box clamping mechanism is an important part of the box stacking machine. Its function is to clamp the designated turnover box. After the lifting mechanism is activated, it cooperates with the supporting mechanism to stack the box to a certain height, so as to achieve the purpose of stacking the box. Now In the prior art, the clamping mechanism based on the air cylinder has a small load-bearing capacity, unstable clamping of heavy objects, expansion of the end, and the error caused by the deformation of the turnover box cannot be eliminated. Contents of the invention [0003] The object of the present invention is to provide a cylinder-based clamping mechanism to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, ...
