Technical Field
[0001] This utility model patent relates to a computer-controlled horizontal knitting machine needle plate assembly structure that prevents the insert and sinker plates from shaking. Background Technology
[0002] The existing 32-pin needle plate assembly structure has thin inserts that are prone to wobbling after assembly with the needle plate, especially at the rear end of the inserts. The heel of the existing sinker plate needs to be fitted with a reinforcing plate to prevent wobbling, which is time-consuming, labor-intensive, and not very accurate. Utility Model Content
[0003] The purpose of this utility model is to solve the existing technical problems by proposing a computer horizontal knitting machine needle plate assembly structure to avoid the shaking of inserts and sinkers.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a computer-controlled horizontal knitting machine needle plate assembly structure for preventing the inserts and sinkers from shaking, comprising a needle plate, a first insert, a second insert, a spacer, a small needle plate, a pressure bar, and a sinker. The needle plate has insert slots, within which are arranged sequentially spaced first and second inserts. Two adjacent first and second inserts form a needle groove. Two mirrored needles of a mirrored needle assembly are positioned within adjacent needle grooves. The pressure bar is positioned within a needle groove located above the needles. The first insert has a toothed plate at the front end of the insert slot corresponding to the first insert, and a settling plate at the front end of the insert slot corresponding to the second insert. The first insert has a first dovetail groove on the upper side of the front end. The spacer is fitted into the first dovetail groove. The lower end of the small needle plate is located on the spacer and is fitted into the first dovetail groove. The small needle plate has an installation groove for the heel of the settling plate to move. The installation groove passes through both ends of the small needle plate and opens at the upper end of the small needle plate. A wire groove is opened on the front and rear ends of the small needle plate, passing through the left and right sides of the small needle plate. A wire is provided in the wire groove. Two wires pass through the corresponding waist-shaped holes.
[0005] Furthermore, a second dovetail groove is formed on the end face of the first insert and the second insert, and the second spacer is fitted into the second dovetail groove to separate and reinforce the ends of the first insert and the second insert.
[0006] Furthermore, the settling plate is shaped like the number 7, with a raised heel at the top and two waist-shaped holes at the top, and a pressure nozzle at the bottom.
[0007] Furthermore, the front end of the first insert is provided with an elastic perforation along the included angle of the front end of the first dovetail groove to increase the size of the first dovetail groove, and the elastic perforation groove makes the front end of the first insert form a spring piece.
[0008] Furthermore, the two ends of the small needle plate are connected to the two ends of the needle plate by bolts.
[0009] Furthermore, the upper surfaces of the first insert and the second insert are provided with a third dovetail groove, a fourth dovetail groove, a fifth dovetail groove, and a sixth dovetail groove, and the pressure bar is provided with a sixth dovetail groove. The third dovetail groove, the fourth dovetail groove, and the fifth dovetail groove on the first insert and the third dovetail groove, the fourth dovetail groove, and the fifth dovetail groove on the second insert are aligned. The sixth dovetail groove on the first insert and the sixth dovetail groove on the second insert are aligned with the sixth dovetail groove on the pressure bar. The third dovetail groove, the fourth dovetail groove, the fifth dovetail groove, and the sixth dovetail groove are respectively provided with a third spacer, a fourth spacer, a fifth spacer, and a pressure bar.
[0010] The beneficial effects of this utility model are: by providing an installation groove for the heel of the settling plate to move through the small needle plate, and by using a steel wire to position and drive the settling plate, the shaking of the settling plate and the complex processing of existing settling plates are avoided. The design of the second dovetail groove avoids the problem of the first and second inserts on the needle plate easily shaking. Attached Figure Description
