Description

Technical Field

[0001] The utility model relates to the technical field of knitting equipment, and more specifically, to a thick and thin insert type needle plate device. Background Art

[0002] A flat knitting machine is a double-needle plate latch needle weft knitting machine. Its cam device is like a set of planar cams. The needle feet of the knitting needles can enter the grooves of the cams. By moving the cams, the knitting needles are forced to move regularly up and down in the needle grooves of the needle plate. Through the actions of the needle hooks and needle tongues, the yarn can be knitted into a knitted fabric. When the knitting needle rises, the coil gradually exits the needle hook, the needle tongue opens, and exits the needle tongue and hangs on the needle bar; when the knitting needle descends, the needle hook hooks the newly laid yarn, pulls and bends it into a coil. At the same time, the original coil disengages from the needle hook, and the new coil passes through the old coil and is connected in series with the old coil. The coil strings formed by numerous knitting needles are interconnected to form a knitted fabric.

[0003] At present, the inserts of the needle plate device are all of corresponding thicknesses. The distances between the knitting needles and the interval distances are equal, and the thread-passing intervals of the knitting needles are also the same. It is impossible to achieve various knitting structures to improve the quality of the knitted fabric; moreover, the inserts of the same thickness also limit the design of the internal structure and cannot maximize the advantages of the internal space.

[0004] Having recognized the deficiencies of the above-mentioned conventional needle plate devices, the applicant of the present invention adheres to the spirit of research and innovation, excellence, combines production practice, and uses professional and scientific methods to propose a practical solution, and thus files an application for this case. Summary of the Utility Model

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a thick and thin insert type needle plate device, which uses two inserts with different thicknesses to achieve different functions and gives full play to the maximum advantages in their respective positions.

[0006] To solve the above technical problems, the present utility model adopts the following technical solutions: A thick-thin insert type needle plate device, comprising: front and rear needle plates, elastic sinkers, thin inserts, thick inserts, and knitting needle pressing blocks. Insert blocks are provided at both the left and right ends of the front and rear needle plates. A number of thin inserts are inserted at intervals along the width direction of the front and rear needle plates, and two knitting needle pressing blocks are inserted between adjacent thin inserts. The elastic sinker and the thick insert are arranged between the two knitting needle pressing blocks, with the elastic sinker located above the thick insert. Knitting needles are arranged below the knitting needle pressing blocks. The thickness ratio of the thin insert to the thick insert is 2:5 to 7:10. The thick inserts and the thin inserts are inserted at intervals on the front and rear needle plates, and there is no restriction on the order of selection. The thin inserts can be inserted at odd positions and the thick inserts at even positions; or the thin inserts can be inserted at even positions and, conversely, the thick inserts at odd positions.

[0007] In the above solution, the thickness of the thin insert is 0.49 to 0.4 mm, and the thickness of the thick insert is 0.87 to 0.71 mm.

[0008] In the above solution, the thickness of the thin insert is 0.49 mm, the thickness of the thick insert is 0.87 mm, the distance between the knitting needles is 1.41 mm, and the alternate needle pitch of the knitting needles is 2.82 mm.

[0009] In the above solution, the thickness of the thin insert is 0.45 mm, the thickness of the thick insert is 0.8 mm, the distance between the knitting needles is 1.21 mm, and the alternate needle pitch of the knitting needles is 2.42 mm.

[0010] In the above solution, the thickness of the thin insert is 0.4 mm, the thickness of the thick insert is 0.71 mm, the distance between the knitting needles is 1.05 mm, and the alternate needle pitch of the knitting needles is 2.12 mm.

[0011] In the above solution, clearance grooves for the knitting needles to slide are provided on one side of both the thin insert and the thick insert, and at least one hole for a steel wire to pass through is provided at the upward extending part of the thin insert.

[0012] Compared with the prior art, the beneficial effects are:

[0013] This application uses two inserts with different thicknesses to replace the original high-low inserts, changing the distance between the knitting needles. The distance between the second knitting needle and the first knitting needle is less than that between the third knitting needle. Similarly, the distance between the third knitting needle and the fourth knitting needle is also smaller, thus changing the spacing of the knitting lines, improving the quality of the knitted fabric, and significantly enhancing the touch of the fabric.

[0014] The structural design of this application can be improved to a certain extent. Just above the thick plug-in is the main displacement cavity of the elastic sinker. When the thickness is increased, the structure of the elastic sinker can be changed to achieve a more excellent effect of pressing and hooking the thread, and the thickness of the elastic sinker can be increased, making the overall structural strength higher and the durability significantly improved.
