Technical Field
[0001] This invention patent relates to a novel needle plate assembly for a horizontal knitting machine. Background Technology
[0002] With the continuous improvement of the intelligence of computerized flat knitting machines, their use is becoming more and more widespread, especially for machines with fine gauge needles. Due to the limitations of the gauge needle, the inserts set in the needle groove are relatively thin. The needle groove formed by the combination of inserts allows the knitting needles to move up and down within it. Due to accidental factors such as needle collisions, the needles are subjected to stress distribution, which can easily impact the inserts. This requires professional needle plate manufacturers to not only professionally configure the tolerance requirements of the inserts and needle plate grooves and apply glue to local areas during the assembly of the inserts and needle plate grooves, but also to reinforce the assembly of the inserts. In addition, due to the thinness of the needles in fine gauge knitting, it is even more necessary to improve the stability of the stitches. This led to the idea of developing a flat knitting needle plate combination structure to solve the instability factors of the existing needle plate structure combination, reduce processing costs, enhance the competitiveness of the industry, and win new development opportunities. Summary of the Invention
[0003] The purpose of this invention is to solve the existing technical problems by proposing a novel needle plate combination for a horizontal knitting machine.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a novel needle plate assembly for a flat knitting machine, comprising a needle plate, inserts, needle rulers, and sinkers. The needle plate has insert slots, and inserts are arranged within these slots. A needle groove is formed between two adjacent inserts, and knitting needles are positioned within the needle groove. A sinker is located at the front end of the insert slot. The inserts are divided into first and second inserts. The insert slot contains first and second inserts arranged sequentially at intervals. A needle groove is formed between two adjacent first and second inserts. Two knitting needles from a mirrored needle assembly are correspondingly positioned within adjacent needle grooves. The lower end of the settling plate is set in the front end of the slot corresponding to the first insert. The upper end of the settling plate has a raised heel. The middle part of the settling plate has two arc-shaped waist-shaped holes. The lower part of the settling plate is a wire pressing nozzle.

The spacer piece includes a first spacer tooth at the rear end, a double-seam gap in the middle, and a second spacer tooth at the front end. The raised surfaces of the first insert piece and the second insert piece are inserted into the first spacer tooth, the two side walls of the first dovetail groove are inserted into the spacer teeth of the corresponding double-seam gap, and the rear side of the upper convex part of the tooth piece is inserted into the second spacer tooth.
[0010] Furthermore, the insert has a protrusion at the front end of the U-shaped groove, and a first dovetail groove is provided at the upper end of the protrusion. The spacer is fitted into the first dovetail groove, and the notch of the U-shaped groove near the protrusion is deeper than the other side.
[0011] A novel needle plate assembly for a horizontal knitting machine includes inserts with a raised groove on the upper end, within which a needle ruler is installed. The inserts are divided into a first insert and a second insert. The insert grooves are further divided into through grooves and non-through grooves spaced apart. The first insert is placed in the non-through groove, and the second insert is placed in the through groove. The needle grooves formed by two adjacent first and second inserts are mirrored needles, each positioned in a corresponding needle groove. The lower end of a sinker is positioned in the front end of the corresponding insert groove of the second insert, and the lower end of the sinker is attached to a sinker seat. The upper end of the sinker has a raised heel, and the lower rear end of the sinker has a third wire hole. The lower front end of the sinker is a thread presser. A small needle plate is placed on the upper side of the front end of the first and second inserts, and the small needle plate has an mounting groove for the sinker heel to move.
[0012] Furthermore, the upper side of the convex groove of the second insert is also provided with a first dovetail groove, the spacer is fitted into the first dovetail groove, the needle is fitted into the bottom of the convex groove, and the pressure strip is fitted into the first dovetail groove and located on the spacer. The spacer includes a first spacer tooth located at the rear end and a double-slit gap in the middle. The raised surfaces of the first insert and the second insert are inserted into the first spacer tooth, and the two side walls of the first dovetail groove are inserted into the spacer teeth of the corresponding double-slit gap.
[0013] A novel needle plate assembly for a horizontal knitting machine includes a needle plate, a first insert, a second insert, a small needle plate, a toothed plate, and a sinker plate. The needle plate has insert slots, in which first and second inserts are arranged sequentially at intervals. Two adjacent first and second inserts form a needle groove. Two needles of a mirror-image needle assembly are correspondingly placed in adjacent needle grooves. The small needle plate is placed on the upper front end of the first and second inserts.

The lower end of the sinker plate is placed in the front end of the insert slot corresponding to the first insert. The upper end of the sinker plate has a protruding heel. The middle of the sinker plate has two arc-shaped waist-shaped holes. The lower part of the sinker plate is a thread pressing nozzle. The second insert has a forward protrusion located above the toothed plate. The forward protrusion has two wire holes. The waist-shaped groove of the sinker plate corresponds to the two wire holes of the second insert. Two wires pass through the corresponding wire holes and waist-shaped holes.
[0014] The beneficial effects of this invention are: the design of two arc-shaped steel wire holes on the protrusion of the toothed plate supports the settling plate and the settling plate swings in an arc-shaped manner guided by two arc-shaped steel wires. The two steel wires maintain the stability of the arc-shaped swing of the settling plate's heel. The arc-shaped swing guide fulcrum of the settling plate is set at a high position, which has the advantage of a large swing amplitude for the same stroke compared with the traditional low fulcrum.
[0015] By setting up a transverse groove with upper and lower interlocking surfaces, a second dovetail groove, and a first spacer, the uniformity and rigidity of the needle groove after the first and second inserts on the needle plate are arranged and assembled in sequence are reinforced. The needle ruler set in the convex groove is relatively close to the tooth surface, which can more effectively control the needle gap, avoid the needles from shaking up and down, improve the stability and reliability when the needles are flipped, and further improve the dimensional accuracy. The cross-section of the needle ruler is rectangular. The rectangular needle ruler has low processing cost, is simple to process, and its accuracy is easy to guarantee, which reduces processing costs and enhances the company's competitiveness in the industry.
