Positive Yarn Guide Mechanism of Computerized Flat Knitting Machine

Abstract

The invention discloses an active type yarn guide mechanism of a computer flat knitting machine and belongs to the technical field of auxiliary components of computer flat knitting machines. The computer flat knitting machine comprises a bedside compartment which is arranged on the top of a machine frame of the computer flat knitting machine. The active type yarn guide mechanism comprises a sliding sleeve yarn guide device, a fixed plate base and a set of pulley yarn guide devices. The sliding sleeve yarn guide device is arranged on the bedside compartment and located below the bedside compartment in the height direction. The fixed plate base is fixed to the top of the machine frame. A yarn guide pulley base fixed plate is fixed to the fixed plate base and is correspondingly arranged below the sliding sleeve yarn guide device. The pulley yarn guide devices are arranged in the length direction of the yarn guide pulley base fixed plate at intervals. By the adoption of the active type yarn guide mechanism of the computer flat knitting machine, the yarn breakage rate is significantly lowered, it is ensured that yarn moves towards the knitting machine in a stable state, and the quality of a knitted object can be ensured.

Description

technical field [0001] The invention belongs to the technical field of auxiliary components of a computerized flat knitting machine, and in particular relates to a positive yarn guide mechanism of a computerized flat knitting machine. Background technique [0002] As known in the industry, the computerized flat knitting machine needs to be equipped with a yarn guide mechanism, which guides the yarn directly drawn from the yarn disc or the yarn sent by the yarn feeder to the knitting mechanism for weaving, and the yarn drawn from the yarn disc or The number of yarns sent by the yarn feeder is adapted to the number of yarns of different colors required by the knitting mechanism of the computerized flat knitting machine, so as to weave fabrics with rich colors and patterns. [0003] The technical information about the yarn guide mechanism can be found in the published Chinese patent documents, such as CN102191618A (adjustable elastic clamping mechanism), CN102704171A (direction...

AI Technical Summary

Problems solved by technology

However, after the applicant has collected a large amount of information from manufacturers of computerized flat knitting machines, and through repeated simulation deduction tests, it has been found that the factors causing yarn breakage are, in addition to the aforementioned yarn quality and knitting environment, To a large extent due to the unreasonable structure of the yarn guide mechanism

Because the yarn is in the process of passing through the yarn clamping device and the yarn insertion hook belonging to the structural system of the yarn guide mechanism, because the yarn clamping device and the yarn insertion hook are static, while the yarn is dynamic, so the yarn is in contact with the yarn clamping device and the yarn insertion hook. When the embedded yarn hook enters the weaving mechanism under intense friction, the greater the friction force, the higher the probability of yarn breakage, and the yarn is prone to tightness and looseness during the process of advancing to the weaving mechanism, which seriously affects the yarn quality. The smooth conveying effect of the weaving mechanism ultimately affects the quality of the fabric

[0006] As can be seen from the above, since the yarn guiding form of the yarn guiding mechanism in the prior art is passive yarn guiding, it has played a side effect on yarn breakage to a certain extent.
