The card reader part of the knitting machine adopts the photoelectric scanning principle, and its performance is reliable. In the 1980s, the first batch of electronic braiding machines to enter the Chinese market was the sk560. This model adopts a card reader input program and performs photoelectric scanning. It can knit 60-needle and 150-row patterns. The improved sk580 type can perform 200-needle full-width scanning and 1 to 4 kinds of wool yarn in one row. Since the card reader part and the needle bed were connected in one piece at that time, dust and fluff were easily mixed into the card reader part, which caused scanning disorder. In recent years, the card reader part and the needle bed have been changed into a separate type and connected with a cable to improve performance. More stable. The new model is designated as sk840, and on this basis, computer-controlled knitting machines with different gauges such as sk830, sk860, and sk890 have been developed, gradually forming a relatively complete series of models suitable for knitting with different wire diameters. The family-based small weaving industry provides an ideal set of knitting tools.


Due to the card reader split structure, a set of card reader ec-1 using this machine can be connected to four different types of silver flute computer knitting machines, which means that the same pattern can be used to pass ec-1 and different The machine is used together to knit extra-thick, thick, medium-thick and fine-thread sweaters. The advantages are self-evident.
When the installation and debugging of the knitting machine meet the above requirements, we can weave. Need to start the needle first, the single needle bed knitting of the knitting machine, that is, the flat needle, in principle, the needle comb is not required, and the needle starting methods are roughly as follows:
1. Separate needle method
First push all the knitting needles participating in the knitting on the needle bed of the main machine to position b, then use a needle pusher plate to push the needle spacer of position b to position d, install the insert board device, and lift the needle bars on both sides of the main machine head Flip it to the 0 position, put down the two embossing brushes, and feed the yarn into the yarn feeder a. After closing the yarn feeder, pull the yarn head to the front, go over the knitting needles, gently push the machine head to knit two rows, and lift it up Embossed brush, continue to weave.
2. Chain hook weave
   First push all the knitting needles that need to participate in the knitting to the d position, and then use the tongued crochet needle to hook the wool one by one to form a continuous broken pattern on the knitting needles. After the loop is hung on the hook, push the head to continue knitting.
3. Hanging wire method
   Push the needle spacers of the knitting needles to the b position, knit a row, and use a piece of waste thread between the knitting needle and the door hook to continue knitting. After knitting, remove the waste thread.
