Blade type elastic needle latch opener for double-faced machine

Abstract

The invention discloses a blade type elastic needle latch opener for a double-faced machine. The blade type elastic needle latch opener comprises an outer sleeve, wherein an outer sleeve pin hole is formed in the outer sleeve, and an outer sleeve limiting groove with two through sides is formed in the through hole end of the outer sleeve; an inner sleeve is arranged in the outer sleeve in a sleeving manner; the blind end of the inner sleeve extends outwards to form a connecting base, and a blade is connected to the connecting base; a first inner sleeve pin hole and a second inner sleeve pin hole are formed in the inner sleeve at intervals; The second inner sleeve pin hole is matched with the outer sleeve limiting groove, positioning pins are connected into the first inner sleeve pin hole and the outer sleeve pin hole correspondingly, and a tension spring is connected between the two positioning pins; and a limiting pin is connected to the second inner sleeve pin hole. The blade type elastic needle latch opener needle opening device is reasonable in structure, rapid and convenient to install, more accurate in needle opening, higher in stability, capable of effectively prolonging the service life, capable of improving the working efficiency during tissue cloth production, high in practicability, capable of effectively developing more market new cloth samples and capable of creating new market benefits.

Description

technical field [0001] The invention relates to the technical field of double-sided machines, in particular to a blade-type elastic latch opener for double-sided machines.
