Description

Composite needle bed in flat knitting machine

Technical Field

The invention belongs to the technical field of knitting machinery, and particularly relates to a flat knitting machine, in particular to a composite needle bed in 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 invention aims to provide a composite needle bed with two rows of knitting needles not influencing each other.

Therefore, the technical scheme adopted by the invention is as follows: 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.

Two or more sections of steel wires are arranged between every two adjacent inserting pieces, the steel wires and the inserting pieces with two sides serving as side walls jointly form a track for the top knitting needle to move, a top knitting needle 'frame' moves on the two sections of steel wires during operation, and meanwhile, a limiting needle gauge or a limiting steel wire above the inserting pieces can limit the top knitting needle. In this case, the movement and the force applied by the top needle are independent of the bottom needle and vice versa.

The top knitting needle rack can move on the two needle rulers during working, and meanwhile, the limiting needle ruler or the limiting steel wire above the inserting piece can limit the top knitting needle.

Detailed Description

Example 1

The compound needle bed described in this embodiment includes a needle bed body 1, and the needle bed body is equipped with a plurality of inserted sheet grooves, and the inserted sheet inslot is provided with inserted sheet 3, has constituted the needle groove of placing bottom knitting needle 2 between the adjacent inserted sheet, and bottom knitting needle 2 is located the below position of two adjacent inserted sheets. The insert 3 is provided with two steel wire holes, a first steel wire 51 and a second steel wire 52 respectively penetrate through the two steel wire holes to be connected with all inserts in series, two sections of steel wires are arranged between every two adjacent inserts, the top knitting needle 4 can be erected on the two sections of steel wires, and the two sections of steel wires support the front end and the rear end of the top knitting needle 4; the position of the insertion piece close to the upper edge is provided with a first needle gauge groove, the first needle gauge 61 penetrates through the first needle gauge grooves of all the insertion pieces, and the first needle gauge plays a limiting role in the top knitting needle to prevent the top knitting needle from upwarping.
