Scissors for automatic shearing device

Abstract

The invention discloses scissors for an automatic shearing device. The scissors comprise scissor bodies, two connection rods, a push-pull rod and a compression spring. The scissor bodies are providedwith a first blade part and a second blade part, wherein the first blade part and the second blade part are opened and closed in an interlaced mode, the first blade part is connected with a first cutter handle, the second blade part is connected with a second cutter handle, and the connection part of the first blade part and the first cutter handle and the connection part of the second blade partand the second cutter handle are hinged mutually, and meanwhile, hinged and fixed to a machine frame. One ends of the two connection rods are hinged mutually and hinged to the tails of the first cutter handle and the second cutter handle, and the two connection rods and the first cutter handle as well as the second cutter handle form a four-connection-rod mechanism. The push-pull rod is connectedwith the hinge position of the two connection rods, and the push-pull rod provides reciprocating telescopic force in the axial direction of the push-pull rod. The outer surface of the push-pull rod issleeved with the compression spring, and the compression spring provides elastic force for enabling the push-pull rod to be close to the direction of the scissors. Simplex tensile force is transformed into cutter edge shearing force in two opposite directions by adopting the scissors, the equipment cost is low, the structure is reliable, and various kinds of silk-shaped pieces can be sheared offconveniently.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a pair of scissors used in an automatic cutting device. Background technique [0002] Some production lines will be equipped with shearing equipment for cutting strips and filaments. The frequency of cutting is high and the shearing force required is large. Manually operated scissors cannot meet the requirements. Contents of the invention [0003] The problem to be solved by the present invention is to provide a pair of scissors for an automatic shearing device, which converts a single pulling force into two opposing knife-edge shearing forces, has low equipment cost, reliable structure, and is convenient for cutting various filaments. [0004] In order to solve the above problems, the present invention provides a kind of scissors for automatic shearing device, in order to achieve the above object, the technical solution adopted by the present invention to solve the technical problems is: [...
