The utility model discloses a frame needle portion is the straight line and goes up reason and both sides constitute the track that supplies the motion of top knitting needle jointly as the inserted sheet body of lateral wall, and during operation top knitting needle "frame" moves on frame needle portion is the straight line and goes up reason, and the motion and the atress of top knitting needle are independent of bottom knitting needle, vice versa.

Description

Composite needle bed for flat knitting machine

Technical Field

The utility model belongs to the technical field of knitting machinery, more specifically relates to flat knitting machine, especially a compound needle bed for 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 leads to an increase in cost and a bulkier machine body.

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: the utility model provides a compound needle bed for flat knitting machine, includes the needle bed body, has a plurality of grooves that parallel on the body, and 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 inserting sheet is provided with a needle frame part, and the needle frame part protrudes out of the side surface of the inserting sheet so that the thickness of the needle frame part is larger than that of the inserting sheet main body; the needle holding part is provided with a section of linear upper edge, and the lower edge of the needle holding part is away from the bottom knitting needle.

Furthermore, a needle gauge groove is further formed in the position, close to the upper edge, of the insertion piece, and the long-strip-shaped needle gauge penetrates through the needle gauge grooves of all the insertion pieces.

The utility model discloses a must contain the frame needle portion of one of them inserted sheet between every two adjacent inserted sheets, frame needle portion is the straight line and goes up reason and both sides constitute the track that supplies top knitting needle motion as the inserted sheet body of lateral wall jointly, and during operation top knitting needle "puts up" and moves on frame needle portion is straight line reason, and the needle gauge of inserted sheet top can provide spacingly to the top knitting needle simultaneously. The lower edge of the needle carrier is independent of the bottom needles, in which case the movement and the force of the top needles are independent of the bottom needles and vice versa.

Drawings

The following detailed description is made with reference to the accompanying drawings and embodiments of the present invention

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the structure of the insert of the present invention;

fig. 3 is a schematic view of the multi-needle bed structure of the present invention.

Labeled as: the needle bed comprises a needle bed body 1, a bottom knitting needle 2, an inserting sheet 3, a needle frame portion 31, a needle gauge groove 32, a top knitting needle 4 and a needle gauge 5.

Detailed Description

See the drawings. 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 inserting sheet 3 is provided with a needle frame part 31, and the needle frame part 31 protrudes out of the side surface of the inserting sheet so that the thickness of the needle frame part is larger than that of the inserting sheet main body; the needle frame part 31 is long strip-shaped, the upper edge is of a linear structure, the top knitting needle 4 is arranged at the upper edge of the needle frame part 31, and the lower edge of the needle frame part is separated from the bottom knitting needle. The position of the insert close to the upper edge is provided with a needle gauge groove 32, the long-strip-shaped needle gauge 5 penetrates through the needle gauge grooves 32 of all the inserts, and the needle gauge has a limiting effect on the top knitting needle 4 to prevent the top knitting needle from upwarping.

The needle holding part of the insert is attached to one side, which does not contain the needle holding part, of the adjacent insert, namely only one needle holding part is arranged between every two inserts, the upper edge and two sides of the needle holding part 31 are used as insert bodies of the side walls to jointly form a track for the movement of the top knitting needle 4, and the top knitting needle 4 is 'held' to move on the upper edge of the needle holding part during operation. The lower edge of the needle frame part is not contacted with the bottom knitting needle, the movement and the stress of the top knitting needle are independent of the bottom knitting needle, and the bottom knitting needle are not interfered with each other.
