Cam device for realizing irregular single-side applique

Abstract

The invention discloses a cam device for realizing irregular single-side applique. With the cam device, missed stitch is avoided during weaving of irregular patterns. The cam device comprises a base plate, a pair of outer raising cams, a pair of inner raising cams, a pair of quality cams, an upper stop cam and a lower stop cam, wherein the two outer raising cams, the two outer inner raising cams and the two quality cams are respectively in axially symmetrical arrangement on the left side and the right side of the base plate, and the upper stop cam and the lower stop cam are in axial symmetrical arrangement on the upper side and the lower side of the base plate. Back cams are arranged below the outer raising cams on the base plate; a press cam is arranged in the middle of the upper stop cam and comprises inverted-trapezoid press members, press slide slots are formed inwards on the press surface of the press member, and a pair of press sliders is arranged in the press slide slots; guide slots matched with the press sliders correspondingly are formed on the base plate, lower portions of the press sliders are disposed in the corresponding guide slots, and one slider resetting mechanism and one slider driving mechanism are arranged between each press slider and the base plate. The cam device is mainly used for non-dashed jacquard computerized transverse knitting machines.

Description

technical field [0001] The invention relates to a jacquard flat knitting machine (abbreviated as a jacquard flat knitting machine), in particular to a jacquard flat knitting machine without dotted lines. Background technique [0002] The jacquard flat knitting machine can be divided into jacquard flat knitting machine without dotted line and jacquard flat knitting machine with dotted line according to whether the jacquard has dotted lines or not. The difference between the two is that the jacquard flat knitting machine without dotted lines is also called the intarsia machine under the guide tower. Hook the yarn. Everyone in the industry knows that the cam device is the center of the flat knitting machine, and the jacquard flat knitting machine is no exception. The needle starting cam, a pair of density cams, and the upper needle stop cam and the lower needle stop cam arranged symmetrically on the lower side of the bottom plate, the back stitch cam and the upper needle stop...

AI Technical Summary

Problems solved by technology

When this kind of triangular device weaves irregular patterns, since the four crochet needles on the top end face of the pressing triangle are always at the same height, when weaving irregular patterns, when the number of yarn needles of a certain color in a certain row of the pattern When it is less, there will be problems when changing the thread. When feeding the thread from the newly fed yarn feeder, the thread that was originally fed on the crochet needle will be punched out, resulting in the phenomenon of missing needles, and the normal knitting jacquard cannot be completed.
