Photoelectric scanning principle of card reader of knitting machine(1)

The card reading part of the braiding machine uses the photoelectric scanning principle, and its performance is reliable. In the 1980s, the first batch of electronic knitting machines to enter the Chinese market was the sk560. This model uses a card reading program to perform photoelectric scanning. It can weave 60-pin, 150-row patterns. After the improved sk580, it can scan 200-pin full-frame and 1 to 4 kinds of wool can be woven in one row. Because the card reader and the needle bed were connected at the time, the reader part was easily mixed with dust and fluff, which caused the scan disorder. Therefore, in recent years, the card reader and the needle bed have been split into separate types. More stable.

The new model is designated as sk840, and on this basis, computer-controlled knitting machines with different stitch specifications such as sk830, sk860, and sk890 have been developed, gradually forming a relatively complete series of models suitable for different wire diameter knitting. The small weaving industry with a family as a unit provides an ideal set of knitting tools.
Due to the split card reader structure, a set of card readers ec-1 using this machine can be connected to four different models of silver flute computer knitting machines. It also means that the same pattern can be used to pass ec -1 is used in combination with different models to knit extra thick, thick, medium and thick sweaters. The advantages are self-evident.
