Technical Field
[0001] This utility model relates to the field of knitting equipment technology, and more specifically, to a front and rear needle plate device suitable for AB needles. Background Technology
[0002] A computerized flat knitting machine is a double-needle plate-latch weft knitting machine. Its cam mechanism acts like a set of planar cams. The needle feet can enter the grooves of the cams, and by moving the cams, the needles are forced to move up and down rhythmically within the needle grooves of the needle plate. Through the actions of the needle hook and the needle latch, the yarn is knitted into fabric. During the upward movement of the needle, the loops gradually exit the needle hook, the needle latch opens, and the loops are hung on the needle bar. During the downward movement of the needle, the needle hook catches newly placed yarn and pulls it to bend into a loop. Simultaneously, the existing loops exit the needle hook, and the new loops pass through the old loops, connecting with them in series. Numerous loops are interconnected to form the knitted fabric.
[0003] Currently, the distance and spacing between the knitting needles in the needle plate device are equal, and the threading distance between the knitting needles is also the same. In order to ensure the knitting quality, if the distance between the knitting needles and the toothed plate is reduced, it is easy to jam or break the knitting thread.
[0004] In view of the shortcomings of the aforementioned existing needle plate devices, and adhering to the spirit of research and innovation and striving for excellence, the applicant, combined with production practice and using professional and scientific methods, proposes a practical solution, and therefore submits this application. Utility Model Content
[0005] To overcome at least one of the defects of the prior art, this utility model proposes a front and rear needle plate device suitable for AB needles, which can be used with A knitting needles and B knitting needles to achieve better knitting results.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a front and rear needle plate device suitable for AB needles, comprising: front and rear needle plates, elastic sinker plates, high inserts, low inserts, and needle pressing blocks. Insert blocks are provided at both ends of the front and rear needle plates. Several high inserts and low inserts are inserted into the front and rear needle plates at intervals along the width direction. Two symmetrically distributed needle pressing blocks are disposed between the two high inserts. An elastic sinker plate and a low insert are disposed between the two symmetrically distributed needle pressing blocks. The elastic sinker plate is located in front of the low insert. A knitting needles and B knitting needles are disposed on the left and right sides of the elastic sinker plate. The needle flipping plates of A and B knitting needles are disposed on the outer side of their respective needle bodies. Toothed plates are respectively mounted on the outer side of A and B knitting needles. The rear sections of A and B knitting needles are thinner than their front sections. A clearance groove for the displacement of the needle flipping plates is provided below the front end of the high insert, which is applicable to situations where the high and low inserts have the same thickness.
[0007] Specifically, the front sections of the A and B knitting needles are knitting parts, the rear sections of the A and B knitting needles are insertion parts, and the low insert is located between the insertion parts of the A and B knitting needles.
[0008] Specifically, a gap of at least 0.05 mm is maintained between the knitting portions of the A knitting needle and the B knitting needle, and the gap is smaller than the distance between the knitting needle and the outer toothed plate.
[0009] Specifically, the inner side of the connection between the knitting part and the insertion part is provided with an inclined tube front, which allows the knitting needle to enter smoothly.
[0010] Specifically, the front end of the low-profile insert is stepped and divided into an extension and a guide. The extension is inserted between two symmetrically distributed needle pressure blocks, and the guide has guide slopes on both sides of its front side.
[0011] Specifically, a partition is provided between the A knitting needle and the B knitting needle, and the partition is inserted into the slot of the front and rear needle plates.
[0012] Specifically, the partition is made of three pieces welded together. The end of the partition has a limiting surface for holding the steel wire in place, and the partition has a round hole for the steel wire to pass through.
[0013] Compared with existing technologies, the beneficial effects are:
[0014] This application uses two symmetrical needle types, A and B knitting needles. By using structural features with different thicknesses at the front and back, the distance between the two knitting needles is reduced, thereby increasing the distance between the knitting needle and the outer toothed plate. This not only increases the amount of yarn but also prevents the yarn from getting stuck and broken when hooking the yarn.
[0015] The partition structure of this application, together with the side teeth, can hold the knitting needle on both sides, restricting the knitting needle laterally and preventing unnecessary shaking of the knitting needle when it is running at high speed; the extension of the low insert is inserted between the knitting needle pressure blocks, and the knitting needle pressure blocks clamp the low insert, improving the stability of the low insert and enabling the device to maintain high-speed operation.

[0024] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.
[0025] like Figures 1 to 6 As shown, a front and rear needle plate device suitable for AB needles includes: front and rear needle plates, elastic sinker plates, high inserts, low inserts, and needle pressing blocks. Both ends of the front and rear needle plates are provided with insert blocks. Several high inserts and low inserts are spaced apart along the width of the front and rear needle plates. Two symmetrically distributed needle pressing blocks are positioned between two high inserts. An elastic sinker plate and a low insert are positioned between the two symmetrically distributed needle pressing blocks. The elastic sinker plate is located in front of the low insert. A knitting needles (A and B) are positioned on the left and right sides of the elastic sinker plate. The needle flippers of A and B knitting needles are positioned on the outer side of their respective needle bodies. Toothed plates are mounted on the outer sides of A and B knitting needles. The rear sections of A and B knitting needles are thinner than their front sections. A clearance groove for the displacement of the needle flippers is provided below the front end of the high insert. The high and low inserts can have the same thickness. The needle flippers on the sides of A and B knitting needles can move back and forth within the clearance groove of the high insert, avoiding interference with the sliding of the needle flippers.
[0026] In the above scheme, the front sections of knitting needles A and B are knitting portions, and the rear sections of knitting needles A and B are insertion portions. A low insert is located between the insertion portions of knitting needles A and B. A gap of at least 0.05 mm is maintained between the knitting portions of knitting needles A and B, which is smaller than the distance between the knitting needle and the outer toothed plate. An inclined tube front is provided on the inner side of the connection between the knitting portion and the insertion portion.
[0027] Knitting needles A and B employ a mirror-symmetrical design, arranged as a group on the front and back needle plates. The thickness of the insertion section at the end of knitting needles A and B is less than that of the front knitting section, and the insertion section can move back and forth between the high insertion section and the low insertion section.
[0028] Compared to the traditional equidistant arrangement, the knitting sections at the front ends of the A and B knitting needles in this application are closer together, with a distance of up to 0.16 mm. The distance between the needles and the toothed plates on both sides can reach 0.26-0.31 mm, which increases the distance between the knitting needles and the toothed plates, allowing two yarns to pass through simultaneously without yarn jamming or breakage.
[0029] In the above solution, the front end of the low-profile insert is stepped and divided into an extension and a guide. The extension is inserted between two symmetrically distributed needle pressure blocks, and the guide has guide slopes on both sides of its front side.
[0030] The extension of the low-profile insert can extend to the space between two needle pressure blocks, where the needle pressure blocks clamp the front end, ensuring sufficient stability during high-speed operation. The knitting needles are driven by their heels, and the connection point between them can smoothly pass through the guide ramp on the guide section. The guide ramp allows them to glide smoothly, preventing jamming.
[0031] In the above scheme, a spacer is provided between the A knitting needle and the B knitting needle, and the spacer is inserted into the groove of the front and rear needle plates. The spacer is made of three pieces welded together, and the end of the spacer is provided with a limiting surface for holding the steel wire. The spacer is provided with a round hole for the steel wire to pass through. The spacer can also be formed by traditional extrusion.
[0032] The spacer is installed on the front and rear needle plates and is fixed by a front steel wire passing through a round hole. Then, a second steel wire is used to hold the limiting surface. By fixing it at two points, it can not only separate the A knitting needle and the B knitting needle to avoid unnecessary wear on the needle body during high-speed operation, but also limit the movement of the A knitting needle and the B knitting needle.
[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description, such as the application of two-system or three-system control plates. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
