AI Technical Summary
It is difficult for existing computer flat machines to achieve ready-to-wear knitting with medium-fine needle pitches. The traditional tongue needles are insufficient in thickness and cannot meet the weaving needs of medium-coarse needle pitches. High-end computers are expensive and the domestic demand is urgent.
A combined needle bed is designed. By setting several longitudinal needle groove insert slots on the main body of the needle bed, the tongue needle, needle guide, thickness and needle selection sheet are installed, and combined with the ring-shifting reed and auxiliary needle groove. Thicken the tongue needle and improve the guide needle track to ensure that the yarn content of the needle hook meets the requirements of medium-fine needle spacing, and realizes ready-made garment knitting with medium-fine needle spacing.
Without changing the movement trajectory and needle selection method of the existing computer flatbed machine, weaving of ready-made garments with medium-fine needle pitch is achieved, with a stable structure, meeting the weaving needs of medium-coarse needle pitch, and reducing equipment costs.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of computerized flat knitting machines, in particular to a combined needle bed for knitting garments on a computerized flat knitting machine. Background Art
[0002] Existing computerized flat knitting machines are restricted by factors such as sweater knitting process plate making, mechanical motion control systems and the pioneering design of key components. The knitting of sweaters has always been limited to the loose knitting of the front and back pieces, two sleeve pieces and the neckline. A complete sweater is formed by manual sewing with a special sweater sewing machine. The sewing process is a labor-intensive and time-consuming process.
[0003] With the improvement of knitting process and plate making, the improvement of control systems and the gradual maturity of pioneering designs in the industry, medium-coarse 7-9 needles / 25.4 mm (the number of latch needles per inch) medium-coarse needle spacing knitting wide-width computer knitting machines (such as 7 needles for a 14-needle plate to increase the width to achieve the actual number of needles needed for a sweater) have been launched on the market. However, the large-scale medium-fine needle spacing such as 11-14 needles is restricted by equipment such as latch needles. If the latch needles are used and installed according to the traditional method, the thickness of the latch needle is less than 0.5, the needle hook is too small and the yarn content is not up to standard, and the unilaterally tightened suspended coil pulls the bent needle hook extension rod and cannot be used for garment knitting.
[0004] After 2000, internationally renowned brands in the industry launched multi-needle-bed computerized flat knitting machines - four-needle-bed computerized flat knitting machines with superimposed front and rear needle beds, and equipped with a needle-selection type thread-pressing auxiliary needle bed, which perfectly realized the "weave and wear" garment knitting with fine gauges of more than 12 needles. It uses complex special composite weaving latch needles, needle beds and composite three-dimensional triangular tracks. The price of a single unit is as high as more than one million, which is about 20 times the price of existing domestic computer machines. Sweater companies cannot afford it, but the demand for the localization of medium and fine gauge garment knitting computer machines is urgent. Summary of the invention
