Description

TECHNICAL FIELD

[0001] The utility model relates to a flat knitting machine field, especially a flat knitting machine insert positioning structure. BACKGROUND

[0002] Computer flat knitting machine is a double needle plate weft knitting machine, through the head and the cam mechanism on the head triangle base plate, that is, the cam system in the process of reciprocating along the guide rail of the head, drive the knitting needle in the needle bed (needle plate) needle groove up and down movement, under the cooperation of the cam mechanism and the pulling mechanism, the knitting of the fabric is completed; wherein, the needle bed is also provided with an insert, which is used for limiting the knitting needle, and the insert can be replaced according to different knitting needles.

[0003] As shown in CN221320260U, Figure 3 Because the length of the insert is longer, generally, the insert is fixed at both ends by pressing strip (only the groove for installing the pressing strip is shown in the figure, and the pressing strip itself is not shown), but even if the pressing strip is used for fixing, due to the density design requirement of the knitting needle, when the knitting needle is dense and the insert is thin, the insert will vibrate due to the vibration generated by the needle bed rocker, thereby affecting the normal work of the flat knitting machine.

[0004] Therefore, the inventor makes further research on this and develops a flat knitting machine insert positioning structure, which is generated in this case. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at providing a flat knitting machine insert positioning structure, which can better stabilize the working state of the flat knitting machine insert.

[0006] In order to realize the above purpose, the technical scheme of the utility model is as follows:

[0007] A flat knitting machine insert positioning structure, comprising

[0008] The insert is provided with a plurality of grooves, and the grooves form a through groove by arranging a plurality of inserts side by side.

[0009] The positioning comb is arranged in the through groove.

[0010] The side of the positioning comb is provided with a spacing tooth, and the spacing tooth cooperates with the groove of the insert.

[0011] The spacing tooth of the positioning comb is arranged to limit the insert, which can prevent the insert from shaking left and right.

[0012] Further, the groove comprises at least a first groove and a second groove.

[0013] Because the insert is longer, the positioning effect is better by using two positioning combs.

[0014] Further, the positioning comb is provided with interval teeth on one side or both sides.

[0015] Further, the interval teeth of the positioning comb are left with a gap from the groove side.

[0016] The positioning comb is mainly used for placing the left and right shaking of the insert piece, in order to facilitate installation, the positioning comb is left with a gap from the groove, which is more convenient for installation.

[0017] Further, the positioning comb is provided with a pressing plate.

[0018] The pressing plate is used for fixing the positioning comb; the pressing plate and the positioning comb are designed as an integrated structure, which is more expensive in processing, therefore, the split type installation design is more optimal.

[0019] Further, the interval between the first groove and the second groove is greater than the activity range of the needle butt of the knitting needle.

[0020] Since the knitting needle moves up and down when working, the needle butt needs a certain activity distance, and the setting of the positioning comb cannot affect the activity of the needle butt.

[0021] After the above scheme is adopted, the utility model has the following advantages compared with the prior art:

[0022] The shaking of the insert piece caused by the needle bed vibration is avoided, the service life of the element is indirectly improved, and the operation precision of the flat knitting machine is improved. BRIEF DESCRIPTION OF DRAWINGS

[0024] Figure 2 is a schematic view after the pressing plate is removed;

[0025] Figure 3 is Figure 2 is a local enlarged view of A in Fig.

[0026] REFERENCE NUMERALS

[0027] Insert piece 1, first positioning comb 2, second positioning comb 3, first pressing plate 4, second pressing plate 5,

[0028] Needle butt 6, gap 7. DETAILED DESCRIPTION

[0029] The utility model will be further described below in combination with the drawings and specific embodiments.

[0030] As Figure 1As shown, a flat knitting machine insert positioning structure is applied to the needle bed of the flat knitting machine, including an insert 1, a first groove and a second groove are opened on the insert 1, and several inserts 1 are arranged side by side so that the first groove and the second groove form a first transverse through groove and a second through groove, a first positioning comb 2 and a first pressure plate 4 are arranged in the first through groove, and a second positioning comb 3 and a second pressure plate 5 are arranged in the second through groove; wherein, the first pressure plate 4 covers the first positioning comb 2, and the second pressure plate 5 covers the second positioning comb 3, and the interval between the first groove and the second groove is larger than the movable range of the needle butt 6.

[0031] like Figure 2 、 Figure 3 As shown, taking the second positioning comb 3 as an example, the upper side of the second positioning comb 3 is a spacer tooth structure. Each second groove corresponds to a spacer tooth unit of the positioning comb, and a gap 7 is left between the second groove and the spacer tooth. The spacer teeth clamp the two sides of the insert 1; the gap 7 allows the second positioning comb 3 to be inserted from bottom to top into the second through-slot formed by the second groove. In this embodiment, the lower side of the first positioning comb 2 is a spacer tooth structure, which is inserted from top to bottom into the first through-slot formed by the first groove.

[0032] Due to the structural properties of the needle bed itself, it is more convenient to use a split design between the positioning comb and the pressure plate in processing and installation. Figure 2 The strip-shaped positioning comb shown is not convenient for direct installation. Therefore, according to its structural characteristics, a first pressure plate 4 is provided on the first positioning comb 2. The first pressure plate 4 can be fixed to the needle bed head by bolts; and the second pressure plate 5 needs to be fixed at both ends.

[0033] like Figure 4 As shown, there are many groove positions that can be opened on the insert, except for the grooves in this embodiment. Figures 1-3 Outside the locations shown in Figure 4 The area marked with a circle can also be processed to form a mounting position, but the principle is the same as that of the aforementioned embodiment and will not be elaborated here.

[0034] The above are only specific embodiments of the present invention. At the same time, all words such as "upper, lower, left, right, middle" involved in the present invention are for reference only and are not absolute limitations. Any non-substantial changes made using the present invention shall be deemed as an infringement of the protection scope of the present invention.
