The invention discloses an instant clamping
mechanism based on
paperboard processing, and relates to the technical field of packaging paper shell
processing, the instant clamping mechanism comprises a base, a connecting plate and a chain arranged on the connecting plate, and further comprises a fixing block fixedly installed on the side wall of the chain, and a long rod is fixedly installed on the fixing block; a
cutting mechanism; the clamping block is rotationally mounted on the long rod; the expansion block is arranged on the long rod; and the stop block is vertically mounted above the base in a sliding manner, and the stop block has a blocking state and a falling-back state. Along with the conveying of the chain, the long rod and the clamping block are driven to get close to the
cardboard, the
cardboard is blocked by the check block to be subjected to position limitation so that the clamping block can directly clamp the
cardboard after reaching the designated position, and in the whole working process, the chain does not need to be stopped, and the conveying of the cardboard does not need to be stopped; and under the condition that the chain does not stop conveying, fixed-point placement and secondary extending clamping conveying can be carried out on the paper shells, so that the whole
machining and conveying process is simpler and more convenient.
