Full-automatic numerical control multifunctional electronic thread-regulation jacquard purl round weft knitting machine

Abstract

The invention discloses a full-automatic numerical control multifunctional electronic thread-regulation jacquard purl round weft knitting machine. A post-jacquard device closely props against the inner wall of a needle cylinder in the knitting process to prevent a triangular mechanism from dropping and ensure high quality of a final product. The triangular mechanism realizes automatic stretching and retraction of a triangular block on the round weft knitting machine to automatically change the knitting track. The drawing and batching tension of a batching mechanism in the entire weaving process can be correspondingly regulated according to the technical requirements so as to realize more stable fabric drawing and batching; and the production process of various gray fabrics and the specification and quality of products can be guaranteed. A needle cylinder driving device realizes automatic control on the rotation speeds of an upper needle cylinder and a lower needle cylinder to adapt to the production of various products, and the product processing precision is improved.

Description

Technical field: [0001] The invention relates to the technical field of circular knitting machines, in particular to a double-back circular weft knitting machine with electronic thread adjustment and jacquard. Background technique: [0002] Application number: 200610050782.5, publication number CN 101074514A discloses a kind of fully computer-controlled multi-functional electronic line-adjusting jacquard double-sided circular weft knitting machine, and its disadvantages are: [0003] 1. Its jacquard device part, such as figure 1 As shown in the figure, the labels are A1-jacquard needle, A2-connecting needle, A3-knitting needle, A4-triangular mechanism, A5-needle cylinder. When the circular knitting machine is working, the jacquard needle A1 on the needle cylinder A5 climbs up the cam mechanism to perform corresponding knitting actions. When the triangular mechanism A4 drives the jacquard needle A1 to work, there is a certain gap between the jacquard needle A1 and the inner...

Problems solved by technology

[0009] 4. Its needle cylinder driving device uses a common motor to drive the upper and lower gears to rotate, thereby driving the needle cylinder fixed on the upper and lower gears to rotate. The rotary belts of the upper and lower needle cylinders of the shape weft knitting machine are constant, and the speed of the upper and lower needle cylinders cannot be controlled, and the effect of numerical control cannot be achieved, so it is impossible to produce knitted circular products of different quality according to needs.

Its upper gear and lower gear are only driven by one gear connecting rod, which can easily cause poor precision and cause the quality of processed products
