Problems solved by technology

[0003] The jacquard piece B and the needle jack C are added with a bending process, which can play a positioning role, otherwise it will affect the service life of the whole machine and the running speed of the machine
[0004] The yarn feed of the jacquard circular weft machine with the thread adjustment mechanism is completed by the action of the jacquard piece and the knitting needle, and the stability of the movement is difficult to control, especially for knitted fabrics with pads, because the needle jack cannot be knit at the tuck position. Hook to yarn, the range of weavable varieties is limited

Abstract

The invention discloses a needle selection and auxiliary thread regulation knitting machine element of a knitting jacquard circular knitting machine, which comprises a novel jacquard sheet, a novel reset positioning triangle, a novel needle propping sheet triangle and an auxiliary middle needle, wherein a needle selector and the jacquard sheet are in effective contact for executing the needle selection action, a triangular guide rail of the back half part of the reset positioning triangle is used for needle selection and positioning on a conical S-shaped elastic sheet structure on the top of the jacquard sheet for reducing the deflected swinging radian and avoiding the generation of adverse phenomena such as confused patterns of knitting materials and the like, the conical S-shaped elastic sheet structure on the top of the jacquard sheet and the N-shaped needle propping sheet can effectively ensure the accuracy of the positioning action of the jacquard sheet, the auxiliary middle needle of the middle needle of the auxiliary thread regulation machine element controls a knitting assembly to carry out independent thread regulation and yarn changing action through being precisely matched with a triangular dual positioning runway, the effect of improving the knitting and yarn changing work to a novel stage of high speed and high stability can be realized, and at the same time, the problems of edge curl and the like of knitting materials can be solved through converting a two-section knitting needle and adopting the edge locking process by the triangles.

Description

technical field [0001] The invention discloses a needle selection and auxiliary thread adjustment knitting machine part of a knitting jacquard circular weft machine, which belongs to the technical field of knitting machinery manufacturing, and in particular relates to a computerized jacquard knitting circular weft machine needle selection system-double positioning of jacquard sheet return and positioning action And auxiliary thread adjustment, making the action of the jacquard needle selection mechanism more high-speed, stable and reliable. Background technique [0002] Known computer jacquard knitting circular knitting machine, its needle selection system - the action of the jacquard sheet is controlled by the return triangle, and its mechanism characteristic parts, refer to Figure 1A , Figure 1C : When the needle cylinder A and the jacquard piece B of the knitting machine are in the working state, the needle selector executes the specified jacquard piece action issued by...
