Description

Technical Field

[0001] This invention relates to a needle plate and needle assembly structure for a computerized flat knitting machine, which is particularly suitable for the needle plate structure of a fully formed flat knitting machine and has practical significance for the development of ultra-fine needle pitch. Background Technology

[0002] The development trend of modern computerized flat knitting machines is towards intelligence, finer needle pitch, high efficiency, multi-functionality, and simplicity. The guiding type of computerized flat knitting machines remains compact, with a base plate, mainly used for producing fully finished high-end products. Sweater manufacturers use ordinary two-needle flat knitting machines with a skipped needle method to achieve one-time garment production, that is, knitting the body, sleeves, and collar all at once, also known as full-finish knitting. However, the needle pitch created by skipped needles cannot reach the standard needle pitch of ordinary flat knitting machines; the needle pitch increases significantly, the arc between loops is long, the density is not tight, and the requirements for the knitting yarn are higher, failing to achieve the overall effect of sweaters knitted with normal needle pitch. The development of higher-gauge machines is to meet the needs of cashmere sweaters and high-end T-shirt production. A published patent (patent number CN) describes a needle plate and needle combination and needle selection mechanism for a flat knitting machine. While patent 111334923 has advantages over the previous method of using a needle-separated needle, its existing patent technology analysis reveals several drawbacks. These include unstable needle output, a tendency to introduce fine needles, and a complex structure that relies on a single-slot double-needle design with needle clockwise switching. This complex structure is prone to occasional malfunctions during operation, leading to fabric quality issues. Furthermore, the needle clockwise switching method requires the knitting head to be moved out of the knitting area during full-bed knitting, significantly slowing down production efficiency. Analysis of the needle plate inserts (also known as needle plate inserts) reveals significant processing difficulties, high insert costs, and a large number of inserts installed on the needle plate, substantially increasing the cost of the needle plate assembly. To overcome the shortcomings of the previously disclosed patent (CN 111334923), it is necessary to continuously improve and research the existing flat knitting machine needle plate combination structure. The idea of ​​designing a needle plate combination structure that is simple in structure, low in cost, provides stable needle output, and improves knitting efficiency has thus emerged. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the existing disclosed technologies, and to design a needle plate and needle combination structure for a computerized flat knitting machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a needle plate and needle assembly structure for a computerized flat knitting machine, comprising an arrangement of a first insert groove structure and a second insert groove structure of the needle plate, an arrangement of a first insert and a second insert, an arrangement of toothed plates and toothed plate pads, an arrangement of spacers and spacer auxiliary pads, and an arrangement of knitting needles and mirror knitting needles. The sinker is alternately squeezed by one side of the knitting needle and the other side of the mirror knitting needle, so that the sinker is offset towards the side that is squeezed, forming a sinker and knitting needle squeezing and offset design.

[0005] A needle plate and needle assembly structure for a computerized flat knitting machine includes a needle plate, a first insert, a second insert, insert positioning wires, needles, mirror needles, toothed plates, toothed plate spacers, spacer spacers, spacer auxiliary spacers, and sinkers. The needle plate has a plurality of first insert slots and second insert slots arranged at equal intervals. The first inserts are installed in the first insert slots, and the second inserts are installed in the second insert slots, arranged in a 1-every-1 configuration within the insert slots of the needle plate. The front end of the insert group consisting of the first and second inserts is limited by the insert positioning wires. Two adjacent needle slots are formed between each pair of adjacent first and second inserts. The needle plate includes two adjacent needle slots: the first needle slot holds a knitting needle, and the second needle slot holds a mirrored knitting needle, arranged in a 1-every-1 configuration. The dividing line between the knitting needle and the mirrored knitting needle corresponds to the second insert plate. A toothed plate is placed at the top of the first insert plate slot on the needle plate, and toothed plate pads are placed on both sides of the toothed plate to tighten over it. The corresponding support foot hooks onto the third step of the needle plate. A spacer pad is placed at the top of the second insert plate slot on the needle plate, and spacer auxiliary pads are placed on both sides of the spacer pad to tighten over it. The corresponding support foot hooks onto the third step of the needle plate. The first insert plate slot and the second insert plate slot are assembled in a 1-every-1 combination. The sinker is installed in the sinker installation notch of the spacer pad in the second slot.

[0006] Furthermore, the needle plate has a first insert slot and a second insert slot. The first slot and the second slot have different processing structures. The first insert slot and the second insert slot are processed in combination according to the needle level. The purpose is to strengthen the connection stability between adjacent heads of the fine needle plate and prevent squeezing and deformation during the processing of the slot. The lower slope of the front side of the first insert slot has a groove to strengthen the assembly stability of the toothed plate and the toothed plate gasket. A third step is provided on the lower front side to hook the toothed plate, the toothed plate gasket, the spacer gasket, and the spacer auxiliary gasket for stability.

[0007] Furthermore, the toothed plate, toothed plate gasket, spacer gasket, spacer auxiliary gasket, and settling plate are all positioned and fulcrumd with upper positioning steel wires, and each has a third step hooked on the lower side of the needle plate; the upper comb plate is placed in the first dovetail groove at the upper opening of the first insert, and a small needle plate fastening block for fastening the small needle plate is also provided in the first dovetail groove. The small needle plate is above the first insert, and the second dovetail grooves of the first insert and the second insert are combined to form the second dovetail groove group. The lower comb spacer is placed in the second dovetail groove group, and a lower comb plate pressure strip is set above the lower comb spacer for positioning. The first insert and the second insert are limited by several needle foot limiting steel wires.

[0008] Furthermore, the first insert corresponds to the first insert slot, and the second insert corresponds to the second insert slot; the front end of the first insert has a notch to accommodate the hook spring sheet, the lower end of the notch is higher than the needle plate, the lower end of the notch is lower than the lower edge of the hook spring sheet, and the upper end of the notch is higher than the upper edge of the hook spring sheet. The second insert is shorter than the first insert, and the front end of the second insert is located behind the knitting needle and mirror knitting needle structure.

[0009] The outer front end of the knitting needle and the mirror knitting needle is also provided with an upper step, which effectively increases the yarn capacity of the knitting needle and the mirror knitting needle; each of the knitting needle and the mirror knitting needle is provided with an extended needle-connecting spring plate, and the spring plates of the knitting needle and the mirror knitting needle are also mirror symmetrical, which increases rigidity and meets the requirements of needle-connecting elasticity, improves the reliability of needle-connecting, and at the same time reduces the noise generated when the machine is running due to excessive elasticity during needle-connecting.

[0010] Furthermore, both the first insert and the second insert are provided with a second dovetail groove for setting the lower combing spacer and the lower combing plate pressure strip, and they correspond to each other. The rear ends of the first insert and the second insert are also provided with a third dovetail groove, in which the first combing spacer is set, and the first combing plate pressure strip is set above the first combing spacer for positioning.

[0011] Furthermore, the upper end of the toothed plate is higher than the needle plate surface but lower than the lower edge of the hook spring plate, which is used to limit the knitting needle and the mirrored knitting needle to prevent the knitting needle or the mirrored knitting needle from swaying left and right.

[0012] Furthermore, the upper end of the spacer is higher than the needle plate surface but lower than the lower edge of the hook spring plate, which is used to limit the knitting needle and mirror needle to prevent the knitting needle or mirror needle from swaying left and right.

[0013] Furthermore, the needle slot is arranged with knitting needles and mirror knitting needles arranged at intervals of 1 to 1 to form a needle plate knitting unit, and the knitting needles and mirror knitting needles are respectively connected to the needle connecting needle feet.

[0014] Furthermore, the knitting needle and the mirrored needle have thinned steps in front of the second insert, so that the knitting needle and the mirrored needle are centered during operation; the front end of the second insert has an extension section that matches the lower end of the notch of the hook spring plate, the upper end of the extension section is higher than the needle plate, and the upper end is lower than the lower edge of the hook spring plate; the thickness of the second insert is t1, and the gap behind the steps of the knitting needle and the mirrored needle at the second insert is greater than or equal to t1 to form a space. During the knitting lifting and lowering process of the knitting needle and the mirrored needle, they will not interfere with the second insert, thus satisfying the knitting lifting and lowering operation space.

[0015] Furthermore, the upper end of the settling plate is installed in the groove of the small needle plate; the lower front edge of the settling plate yields to the wire passage hole of the toothed plate cylinder, the lower inner edge of the settling plate yields to the upper end of the spacer, the lower end of the settling plate is installed in the second groove and the rear of the lower end of the settling plate is installed in the settling plate installation notch, the spacer and the spacer auxiliary spacer are positioned against the structural surface on the front side, the support foot hooks onto the third step opened in the needle plate, and the rear spring end plays a role in fixing the position.

[0016] Furthermore, the opposite sides of the knitting needle and the mirror knitting needle are provided with a first clearance groove on the upper end of the corresponding spacer pad; the front end of the opposite sides of the knitting needle and the mirror knitting needle is provided with a second stepped surface with reduced thickness. The second stepped surface is used for the knitting needle and the mirror knitting needle to contact the sinker when working. The spacer pads on both sides of the spacer pad are also provided with a first installation notch corresponding to the sinker installation notch on the spacer pad; the thickness of the two first installation notches and the sinker installation notch is greater than or equal to the thickness of the sinker; the gap formed by the reduced thickness of the front end of the opposite sides of the knitting needle and the mirror knitting needle through the second stepped surface is greater than or equal to the thickness of the sinker. The knitting needle or the mirror knitting needle moves out of the toothed plate slightly off-center. At the same time, when the knitting needle or the mirror knitting needle moves out of the toothed plate, it squeezes the sinker to move and deviate, which increases the thickness of the knitting needle head and thus improves the knitting effect.

[0017] A needle plate and needle assembly structure for a computerized flat knitting machine includes a needle plate with a plurality of first insert slots and second insert slots arranged at equal intervals. The first inserts are installed in the first insert slots, and the second inserts are installed in the second insert slots, spaced one apart. The front end of each insert group (first and second inserts) is limited by insert positioning wires. Two adjacent needle slots are formed between each pair of first and second inserts. Each needle slot includes an adjacent first needle slot and a second needle slot. A knitting needle is placed in the first needle slot, and a mirrored knitting needle is placed in the second needle slot, arranged one apart. The dividing line between the knitting needle and the mirrored knitting needle corresponds to the second insert. A toothed plate is placed at the top of the first insert slot on the needle plate, and toothed plates are placed on both sides of the toothed plate. The pads are tightly fitted, and the lower side of each has a third step hooked by the needle plate 1. A sinker is set at the upper opening of the second insert slot of the needle plate. The first insert slot and the second insert slot assembly are arranged in a 1-alternate combination. The front end of the opposite side of the knitting needle and the mirror knitting needle has a second step surface with reduced thickness. The second step surface is used for the knitting needle and the mirror knitting needle to contact the sinker when working. The gap formed by the reduced thickness of the front end of the opposite side of the knitting needle and the mirror knitting needle through the second step surface is greater than or equal to the thickness of the sinker. The gap behind the second step surface is less than the thickness of the sinker. The knitting needle or the mirror knitting needle moves out of the toothed plate slightly off-center. At the same time, when the knitting needle or the mirror knitting needle comes out, it squeezes the sinker to move and deviate, which increases the thickness of the knitting needle head, thereby improving the knitting effect.

[0018] Furthermore, the opposite sides of the knitting needle and the mirror knitting needle are provided with a first clearance groove on the upper end of the corresponding spacer pad; the front end of the opposite sides of the knitting needle and the mirror knitting needle is provided with a second stepped surface with reduced thickness. The second stepped surface is used for the knitting needle and the mirror knitting needle to contact the sinker when working. The spacer pads on both sides of the spacer pad are also provided with a first installation notch corresponding to the sinker installation notch on the spacer pad; the thickness of the two first installation notches and the sinker installation notch is greater than or equal to the thickness of the sinker; the gap formed by the reduced thickness of the front end of the opposite sides of the knitting needle and the mirror knitting needle through the second stepped surface is greater than or equal to the thickness of the sinker; the gap behind the second stepped surface of the knitting needle and the mirror knitting needle is less than the thickness of the sinker; the second insert is provided with a concave notch below the second dovetail groove for the movement of the knitting needle and the mirror knitting needle. The knitting needle or the mirror knitting needle moves out of the toothed plate slightly off-center. At the same time, when the knitting needle or the mirror knitting needle moves out of the toothed plate, it squeezes the sinker to move and deviate, which increases the thickness of the knitting needle head and thus improves the knitting effect.

[0019] The advantages are: the first and second insert slot structures on the needle plate ensure a robust opening structure; the second insert effectively provides sufficient space for the knitting needles and mirror needles during operation; the toothed plate and spacer provide steps on each side of the knitting needles and mirror needles to prevent excessive wobbling and the formation of fine needles when the needles or mirror needles exit the needle slot; and when the knitting needles move up and down within the needle slot, one side of the needle presses against the other side of the sinker plate, causing the sinker plate to shift towards the side that is pressed, thus preventing the mirror needle from moving within the needle slot. During the lifting and lowering process, one side of the mirror needle presses against one side of the sinker plate, causing the sinker plate to deviate towards the side being pressed. Since the knitting of the needle and the mirror needle is alternating, the needle pressing the sinker plate deviates from the structure, maximizing the thickness setting of the needle head participating in the knitting and improving the rigidity of the needle head participating in the knitting, thereby improving the optimization effect of the knitting, which is the best feature of this structure. The second insert is further optimized so that the needle and the mirror needle do not need to be set with steps, which can better meet the performance and processing convenience of the needle and the mirror needle.

[0020] The addition of combing plates and pressure strips further improves the uniformity of the needle groove width and strengthens the interlocking plates to prevent them from shaking. The cost of setting up interlocking plates is low. The knitting needles or mirror knitting needles emerge from the slightly central area of ​​the toothed plate, which improves the knitting effect. Since the knitting needles or mirror knitting needles have their own independent connecting needle feet, compared with the previously disclosed single-groove double-needle structure, this new needle plate combination structure has stable control and high production efficiency.
