Technical Field

The utility model relates to a transfer device, especially a curved surface thin plaque snatchs mechanism.

Background

The bamboo plaque is commonly used in the field of agricultural product drying, and due to the hollow structure of the thin bamboo plaque and the characteristics of the manufacturing and bamboo products, each bamboo plaque can be warped to different degrees under the influence of high-temperature drying, so that irregular space curved surfaces are formed. The bamboo plaques are stored in a stacking mode when being stored, but are used in a single mode, so that when the single bamboo plaque is required to bear agricultural products, one bamboo plaque needs to be taken out from the stacked bamboo plaques for use, and due to the deformation of the bamboo plaque, the stacked bamboo plaques are difficult to be automatically fed and reformed one by one when the bamboo plaque is taken, manual assistance is needed, and labor and time are consumed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's weak point, and provide a curved surface thin plaque that can realize carrying out the automation to the bamboo plaque of piling up and snatching the material loading and carry out the unloading and pile up snatchs the mechanism.

A curved surface thin plaque gripping mechanism, which comprises a track, a self-adaptive gripping device, a limiting feeding frame and a driving device, the track is arranged above the limit feeding frame, the driving device is provided with a slide block type fixing piece, the sliding block type fixing piece slides on the rail, the self-adaptive grabbing device comprises a plurality of self-adaptive grabbing mechanisms for grabbing the bamboo plaque, a lifting device for driving the self-adaptive grabbing mechanisms to do lifting motion and a horizontal moving device for enabling the self-adaptive grabbing mechanisms to do horizontal reciprocating motion, the horizontal moving device is arranged on the lifting device, the self-adaptive grabbing mechanism is arranged on the horizontal moving device, the limiting feeding frame is positioned below the self-adaptive grabbing device and used for stacking the bamboo plaques, the horizontal moving device drives the self-adaptive grabbing mechanism to move by utilizing a hydraulic cylinder or an air cylinder to control the self-adaptive grabbing mechanism to move.

The utility model discloses an automatic machine that shifts that snatchs of thin plaque, when using, the bamboo plaque piles up in spacing material loading frame, drive arrangement drive self-adaptation grabbing device elevating gear drives and snatchs the mechanism and be in the two bamboo plaque clearances of the top layer that the descending motion reachd spacing material loading frame and secondary top layer, then realize pressing from both sides tight to top layer bamboo plaque at drive horizontal migration device, then the re-drive elevating gear drives and snatchs the mechanism and be the rising movement, it can move production line department with self-adaptation grabbing device and put the production line on to recycle the characteristics that drive arrangement can move on the track.
