Description
Technical field
The present invention relates to a kind of calculation methods of circular knitting machine active yarn transmission mode thread-feeding amount, belong to textile process technology neck
Domain.
Background technique
Yarn-feeding mechanism is an important device of circular knitting machine.Major part jacquard circular knitting machine is sent using passive type at present
Yarn is backed off from creel by means of the tension that loop-forming element when braiding generates yarn and guides to woven extent by yarn.According to
Yarn speed is sent in the consumption yarn amount difference change of each moment, but tension can generate certain fluctuation when yarn enters woven extent, so that
Coil size has certain difference, and it is smooth to influence cloth cover.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of calculating of circular knitting machine active yarn transmission mode thread-feeding amount
Method.
The present invention is achieved through the following technical solutions:
A kind of calculation method of circular knitting machine active yarn transmission mode thread-feeding amount, including the following steps:
(1) flower pattern technique imports weft-knitted fabric computer aided system, and system obtains the institutional framework of flower pattern；
(2) by selecting the machine number and cam system triangle sinking depth of circular knitting machine, determine yarn in braiding lopping, tuck
When with flotation line, single coil structure length of yarn；
(3) according to circular knitting machine maximum speed and machine total needle amount, when calculating circular knitting machine is run with maximum speed, one piece of knitting needle
Complete the time that coil braid needs；
(4) according to circular knitting machine servo motor response frequency, the response time of servo motor is learnt；
(5) one piece of knitting needle completes coil braid needs when being run according to servo motor response time and machine with maximum speed
Time, calculate knitting needle complete the coil braid time be greater than the servo motor response time minimum knitting needle quantity；
(6) knitting needle not less than the minimum knitting needle quantity numerical value calculated in (5) is chosen, knitting needle carries out line by cam system
Circle braiding, the length of yarn that braiding needs when completing；
(7) length of yarn needed when being completed according to braiding obtains the thread-feeding amount of yarn storage wheel.
A kind of calculation method of circular knitting machine active yarn transmission mode thread-feeding amount is fallen into a trap with choosing not less than step (5)
The length of yarn that the knitting needle braiding of the minimum knitting needle quantity numerical value of calculation needs corresponds to yarn storage wheel thread-feeding amount.
A kind of calculation method of circular knitting machine active yarn transmission mode thread-feeding amount in step (6), chooses knitting needle numerical value etc.
The minimum knitting needle quantity calculated in step (5).
A kind of calculation method of circular knitting machine active yarn transmission mode thread-feeding amount, in step (1), system obtains flower pattern group
While knitting structure, carries out flower pattern and decompose to obtain weave diagram.
Advantageous effects of the invention:
By calculating the length of yarn of certain amount knitting needle woven stitch structure, yarn storage wheel can basis in the weaving process
Braiding need length of yarn change thread-feeding amount, guarantee constant tension when yarn enters woven extent, reduce identical coil it
Between difference in size so that decorative pattern is more clear, cloth cover is more smooth, greatly improves the quality and aesthetics of fabric.
Calculation method of the invention is simple, can be derived that the thread-feeding amount that yarn storage wheel conveys as needed, greatly improves
The speed and quality of fabric processing.
Detailed description of the invention
Fig. 1 is the calculation flow chart for the calculation method that a kind of jacquard circular knitting machine positive type of the present invention send yarn mode thread-feeding amount；
Fig. 2 is the flower pattern plan of weave of fabric in embodiment 1.
