Automatic tying machine for tying crabs and method thereof

Abstract

The invention discloses an automatic tying machine for tying crabs and a control method thereof. The automatic tying machine for tying crabs comprises a telescopic clamping jaw device, a fixed clamping jaw device, a sucker gripping device, a knotting and tying machine, a rotating sucker worktable and a hopper type collector. In use, a worker only needs to place crabs on suckers on the rotating sucker worktable, the crabs are firmly sucked by the vacuum suckers and are conveyed below the sucker gripping device by the rotating sucker worktable, and the crabs are placed between a telescopic clamping jaw and a fixed clamping jaw by the sucker gripping device; at the moment, the telescopic clamping jaw moves, and the crabs are fixed by the clamping jaws on the two sides; the knotting and tying machine begins tying the crabs and knotting, and then, the clamping jaws loosen; the sucker gripping device sucks the crabs, drives the crabs to rotate for 90 degrees, and then places down the crabs again; the clamping jaws firmly grip, and the knotting and tying machine ties the crabs and knots; and after tying and knotting are finished, a support carrier plate of the telescopic clamping jaw device retracts backwards under the control of an air cylinder, and the crabs tied in a crossed manner fall into the hopper type collector. The automatic tying machine for tying crabs is simple in structure and convenient to operate and reduces the labor intensity of workers.
