Film clamping mechanism

Abstract

The invention discloses a film clamping mechanism, comprising a sliding rail seat, a clamp, a conveying chain and a control drive mechanism for driving the conveying chain to move back and forth, wherein the sliding rail seat is convexly provided with a long rail side and a short rail side, the long rail side and the short rail side constitute a first guide slot, the outer side of the short rail side constitutes a second guide slot, and the first guide slot is divided into an import slot and a straight slot; the conveying chain is vertically spanned in the first guide slot, the clamp is fixed on the conveying chain and comprises a first clamping plate, a second clamping plate and a torsion spring, and the first clamping plate and the second clamping plate are connected with each other by virtue of the coordination between the torsion spring and a connector; and the first and second clamping plates are provided with a first clamping head and a second clamping head respectively in an upward extension manner, the first clamping head and the second clamping head are respectively provided with a clamping part, the first clamping plate is provided with a first pulley sliding along the inner side edge of the long rail side, the second clamping plate is provided with a second pulley sliding along the inner and outer side edges of the short rail side, and the first and second pulleys are located below a central shaft of the torsion spring. The film clamping mechanism disclosed by the invention has the characteristics of simple structure, simpleness and easiness for operation, stability, reliability and the like.

Description

technical field [0001] The invention relates to a film clamping device, in particular to a film clamping mechanism applied in the production process of block bricks. Background technique [0002] Stacking operation is an important production process in the manufacture of block bricks. In the stacking process, the main operation is to separate the block bricks from the pallet, and stack the separated block bricks up and down. In order to prevent each layer from The bricks are adhered to each other, and a film layer is evenly spaced between the adjacent two layers of bricks stacked. During the operation, the film is laid by the sandwich device, that is, a layer of block bricks is stacked, and the film device controls the operation to move the block bricks. Lay a layer of film on it, and do it repeatedly. In the existing clamping device, the structure of the clamping mechanism for clamping the film is relatively complicated, and the clamping stability is relatively poor. Con...
