Description

Composite needle bed in flat knitting machine

Technical Field

The utility model belongs to the technical field of knitting machine, more specifically relates to flat knitting machine, especially compound needle bed among the flat knitting machine.

Background

The needle bed is one of the most important parts of the flat knitting machine, and in the traditional flat knitting machine, a pair of needle beds are arranged oppositely at a certain angle. The needle bed is provided with a plurality of parallel grooves, various knitting needles are accommodated in the grooves, and the knitting needles reciprocate along the grooves according to set instructions, so that knitting is completed. In order to obtain better knitting effect, some flat knitting machines adopt a multi-needle bed design, namely four or more needle beds are provided, each needle bed is provided with a row of knitting needles, and thus four rows or more rows of knitting needles participate in knitting. Such a flat knitting machine has more knitting functions, but the increase of the needle bed will increase the cost and the machine body will be bulkier.

Chinese patent CN109825940A discloses a multilayer insert and a compound needle bed containing the same, which actually proposes the concept of "compound needle bed", i.e. two rows of knitting needles are arranged on one needle bed. Specifically, the technical scheme is that inserting sheets and spacing sheets are arranged on a needle bed at intervals, namely a spacing sheet is arranged between every two inserting sheets, the spacing sheet is approximately triangular, a bottom knitting needle is arranged at the bottom of each spacing sheet, and a top knitting needle is arranged above the spacing sheet. The composite needle bed thus formed has one row of bottom needles and one row of top needles, i.e. two rows of needles are realized on one needle bed. The composite needle bed is analyzed from stress, a bottom knitting needle is supported by the needle bed, and meanwhile, the bottom edge of the spacing piece is used for limiting to prevent the spacing piece from upwarping; the top needle is supported by a top edge of the spacer, while being restrained by other elements, such as a molding strip. In this stressed state, the pressure of the top knitting needle against the spacer is actually transmitted to the bottom knitting needle; likewise, the tendency of the bottom needles to warp up is also transferred to the top needles through the spacers. Obviously, this is not favourable to the respective movements of the two rows of needles.

Disclosure of Invention

The utility model aims at providing a two compound needle beds that knitting needle does not influence each other.

Therefore, the utility model discloses a technical scheme is like this: composite needle bed in flat knitting machine, including the needle bed body, have a plurality of grooves side by side on the body, the inslot is provided with the inserted sheet, is equipped with bottom knitting needle, its characterized in that on the needle bed body between two adjacent inserted sheets: the insert is provided with at least two steel wire holes and/or needle gauge grooves which are positioned on the same straight line, and the steel wire and/or the needle gauge penetrates through the steel wire holes and/or the needle gauge grooves to be connected with all the inserts in series.

Furthermore, the position of the insert close to the upper edge is also provided with at least one position-limiting needle ruler groove, and the position-limiting needle ruler penetrates through the position-limiting needle ruler grooves of all the inserts.

Furthermore, the inserted sheet still is equipped with two at least spacing steel wire holes near the upper edge department, and all inserted sheets are established ties to spacing steel wire.

The utility model discloses an all have two sections or above steel wire between per adjacent two inserted sheets, steel wire and both sides constitute the track that supplies top knitting needle motion as the inserted sheet of lateral wall jointly, and during operation top knitting needle "frame" moves on two sections steel wires, and spacing needle gauge or the spacing steel wire of inserted sheet top can provide spacingly to the top knitting needle simultaneously. In this case, the movement and the force applied by the top needle are independent of the bottom needle and vice versa.

The utility model discloses can trade the steel wire for the needle bar, set up two needle bar grooves that are located same straight line on the inserted sheet, the needle bar passes the needle bar groove, constitutes the track that supplies top knitting needle motion jointly as the inserted sheet of lateral wall with both sides, and during operation top knitting needle "frame" moves on two needle bars, and spacing needle bar or spacing steel wire of inserted sheet top can provide spacingly to the top knitting needle simultaneously.
