Specific implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1-11As shown: a split-type sliding triangle sinker bar device, including a mother board 100, a needle cleaning slide plate 200 and a sinker slide plate 300 arranged behind it. There are three sets of sinker systems 400 with the same design on the mother board 100. The sinker system 400 is composed of two sets of sinker mechanisms 420, a reset triangle 430, and a set of needle cleaning mechanisms 410. The needle cleaning mechanism 410, the sinker mechanism 420, and the reset triangle 430 are arranged in sequence from the inside to the outside in the sinker system 400. Among them, the sinker mechanism 420 has a sinker triangle 421 and a needle pushing triangle 422, and the needle cleaning mechanism 410 has a needle cleaning triangle 411. The sinker triangle 421 is used to select specific elastic sinker blades 800 to participate in the whole yarn pressing process. The needle cleaning triangle 411 is used to deflect and retract this part of the elastic sinker blades 800 at a specific position so that they do not participate in the yarn pressing work temporarily. The needle pushing triangle 422 is used to deflect and extend this part of the elastic sinker blades 800 deflected and retracted by the needle cleaning triangle 411 again so that they participate in the yarn pressing work for the second time, thereby completing some difficult knitting methods.

[0031] Further, the above-mentioned needle cleaning triangle 411 with the function of deflecting and retracting the elastic sinker blade 800 only has an upper triangle itself. The above-mentioned needle pushing triangle 422 with the function of deflecting and extending the elastic sinker blade 800 only has a lower triangle itself. And the above-mentioned sinker triangle 421 for selecting the elastic sinker blade 800 to participate in the yarn pressing process has two design forms. One of them can be provided with both an upper triangle and a lower triangle itself (as shown in Figure 2 ), if so, its up and down movement can directly deflect and retract the elastic sinker blade 800, so it has both the selection and reset functions of the elastic sinker blade 800. The other is only provided with a lower triangle (this design form is not shown in the figure). If so, it can only push and extend the retracted elastic sinker blade 800, that is, it can only realize the selection function of the elastic sinker blade 800, and the reset of the elastic sinker blade 800 is realized by the reset triangle 430.

[0032] Further, since the above-mentioned reset triangle 430 functions to reset the elastic sinker blade 800 in the sinker system 300, it is directly fixed on the mother board 100 itself. Of course, for different sinker systems on the mother board 100, if the reset triangles 430 of each other are adjacent, an integral molding design is allowed between the reset triangles 430.

[0033] Further, the above-mentioned cleaning needle triangle 411 of the cleaning needle mechanism 410 is fastened to a cleaning needle slider 413 located in the cleaning needle transverse groove 101 provided on the mother board 100 with a round-headed screw 412 as a fastener. The head of the screw 412 penetrates into the screw hole preset on the above-mentioned cleaning needle slide plate 200. When the cleaning needle slide plate 200 slides horizontally due to driving, it can drag the cleaning needle triangle 411 to a designated position by means of the screw 412 and the cleaning needle slider 413.

[0034] Further, the above-mentioned sinker longitudinal groove 102 and the needle pushing longitudinal groove 103 opened on the mother board 100 are provided with a sinker slider 423 and a needle pushing slider 424 that can slide up and down. The sinker triangle 421 and the needle pushing triangle 422 are installed at the front ends of the sinker slider 423 and the needle pushing slider 424, thus jointly forming the above-mentioned sinker mechanism 420. When the sinker slide plate 300 slides horizontally due to driving, it can drive the sinker triangle 421 and the needle pushing triangle 422 to perform a lifting action by means of the sinker slider 423 and the needle pushing slider 424.

[0035] Specifically, the above-mentioned sinker slide plate 300 is formed with a sinker guide groove 301. The sinker guide groove 301 is in an inverted "V" shape with high ends and a low middle part, and an arc structure is also used for transition at the connection of the high and low positions. Sinker bottom plates 425 and needle pushing bottom plates 426 fixed to the backs of the above-mentioned sinker slider 423 and needle pushing slider 424 correspondingly have sinker guide wheels 427 and needle pushing guide wheels 428. The sinker guide wheels 427 and needle pushing guide wheels 428 are jointly located in the sinker guide groove 301. When the sinker slide plate 300 slides horizontally, it can drive the sinker triangle 421 and the needle pushing triangle 422 to lift through the cooperation of the sinker guide groove 301 and the two guide wheels.

[0036] As described above, since the elastic sinker 800 itself has an elastic pressure foot 802 for providing yarn pressing pressure, the elastic pressure foot 802 realizes pressing deformation by cooperating with the insertion plate of the needle plate assembly (the rest of the flat knitting machine, not shown in the figure). When the elastic sinker 800 is toggled to expand and contract, the rebound force of its elastic pressure foot 802 may cause the elastic sinker 800 to be unable to be toggled, and even due to the existence of the rebound force, the head of the elastic sinker 800 may directly crush the coil instead. Therefore, this design overcomes the generation of this problem through several convex parts provided by the sinker system 400. Such as Figure 2As shown, the convex portions specifically include a first convex portion 4111 directly formed on the needle cleaning triangle 411, and a second convex portion 4311 and a third convex portion 4312 formed on the extension portion 431 provided on the reset triangle 430 and corresponding to the pusher triangle 422 and the sinker triangle 421 in sequence. When the elastic sinker 800 is toggled and retracted, the convex portions can continuously abut against its trailing edge, thereby restricting its elastic presser foot 802 and preventing it from rebounding; similarly, when the elastic sinker 800 is toggled and extended, since the convex portions abut against its trailing edge, they can also appropriately reduce the rebounding force of the elastic presser foot 802 to reduce the threat of the head of the elastic sinker 800 to the coil.

[0037] Further, the installation methods of the above-mentioned needle cleaning slide plate 200 and sinker slide plate 300 are realized through a fixed seat 500 and a slide plate seat 600 that are spliced front and back; as Figure 3 , Figures 5-6 , Figure 10 shown, convex protrusions 601 are formed on both the upper and lower sides of the back surface of the slide plate seat 600. The upper convex protrusion 601 directly passes through a preset avoidance groove 201 of the needle cleaning slide plate 200. After the slide plate seat 600 is assembled with the fixed seat 500 through the upper and lower convex protrusions 601 and fastened by fasteners, a clamping opening can be formed. The needle cleaning slide plate 200 and the sinker slide plate 300 can only slide left and right in the clamping opening and will not break away outward.

[0038] Specifically, as a way to limit the sliding stroke of the needle cleaning slide plate 200, the above-mentioned slide plate seat 600 is further formed with a needle cleaning limit groove 602. The above-mentioned screw 412 as a fastener passes through the needle cleaning limit groove 602, and the cooperation between the screw 412 and the needle cleaning limit groove 602 can be used to limit the lateral sliding distance of the needle cleaning slide plate 200.

[0039] Specifically, as a way to limit the sliding stroke of the sinker slide plate 300, a stop block 603 is formed on the lower convex protrusion 601 of the above-mentioned slide plate seat 600, and a sinker limit groove 302 is formed at the bottom of the sinker slide plate 300. The cooperation between the stop block 603 and the sinker limit groove 302 can be used to limit the lateral sliding distance of the sinker slide plate 300.

[0040] Further, racks 700 are fixed to the back surfaces of the above-mentioned needle cleaning slide plate 200 and sinker slide plate 300. The racks 700 of the needle cleaning slide plate 200 and the sinker slide plate 300 are each connected to a driving element, so as to be able to pull the needle cleaning slide plate 200 and the sinker slide plate 300 to slide independently. The driving element can be a cylinder, a motor or other similar components (not shown in the figure).

[0041] The working principle of this design is generally the same as that of the existing sinker bar device. For reference, please refer to the applicant's prior patents with the publication numbers of "CN222499583U" and "CN222513023U". Briefly speaking, it is to select specified elastic sinkers through the sinker triangle to participate in the yarn pressing process, and then use the needle cleaning triangle and the needle pushing triangle to realize the secondary expansion and contraction of this part of the elastic sinkers, so that the knitting equipment can complete more complex knitting methods.

[0042] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
