[0002] The elastic sinker is a sinker with an elastic presser foot. Like the traditional sinker, it is driven to retract by the Sink triangle of the Sink device in the flat knitting machine, so as to determine whether it participates in the yarn pressing work. When the Sink triangle drives the elastic sinker to retract, it needs to overcome the rebound force of its elastic presser foot to avoid losing the coordination with the elastic sinker. Therefore, the applicant designed a new Sink device for driving the elastic sinker and filed the following application. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0028] like Figure 1-Figure 8 As shown: a new type of sinker device for driving an elastic sinker, comprising a motherboard 100 and a slide plate 200 arranged front and back, the motherboard 100 has three sets of sinker systems 300 with the same design, the sinker system 300 is composed of two groups of sinker triangles 310, a reset triangle 320, and a group of limit devices 330, wherein the limit devices 330, the sinker triangle 310, and the reset triangle 320 are arranged in sequence from the inside to the outside in the sinker system 300, and the sinker triangle 310 and the reset triangle 320 need to be respectively arranged on both sides of the limit device 330. The sinker triangle 310 can move up and down due to the left and right sliding of the slide plate 200, thereby driving the elastic sinker 700 to extend or retract itself through the needle butt 701 of the elastic sinker 700. If the elastic sinker 700 is in an extended state, the corresponding yarn pressing work can be participated in with the help of the limit device 330.

[0029] Furthermore, the above-mentioned signal triangle 310 and reset triangle 320 both have an upper triangle and a lower triangle, and the needle butt 701 of the elastic sinker 700 can pass through the needle path formed between the upper triangle and the lower triangle.

[0030] Furthermore, since the reset triangle 320 in the signal system 300 serves to reset the elastic sinker 700, it is directly fixed on the motherboard 100. Of course, if the reset triangles 320 of different signal systems 300 on the motherboard 100 are adjacent to each other, an integrated molding design is allowed between the reset triangles 320.

[0031] As described above, the elastic sinker 700 itself has an elastic presser foot 702 for providing yarn pressing pressure. The elastic presser foot 702 is specifically deformed by pressing in cooperation with the plug plate of the needle plate assembly (the rest of the horizontal knitting machine, not shown in the figure). When the downward-moving sinker triangle 310 attempts to retract the elastic sinker 700 through driving cooperation, the elastic presser foot 702 will seek a rebound opportunity due to the deformation. If not restricted, the rebound force will cause the needle butt 701 of the elastic sinker 700 to lose the matching relationship with the sinker triangle 310, that is, the elastic sinker 700 cannot be moved. Therefore, the above-mentioned reset triangle 320 is also formed with an extension portion 321 in the direction of the sinker triangle 310, and the thickness of the extension portion 321 will be greater than the needle track depth of the sinker triangle 310 to a certain extent. Figure 7 As shown, the signal triangle 310 moves down to a lower position, and because the machine head moves horizontally and cooperates with the needle butt 701 of the elastic sinker 700, the rear edge 703 of the elastic sinker 700 will continue to press against the front side of the extension part 321. At this time, the signal triangle 310 and the extension part 321 restrain the elastic sinker 700 in both directions, so that its elastic presser foot 702 cannot rebound, and the elastic sinker 700 can therefore be normally pulled back.

[0032] Furthermore, the limiting device 330 in the above-mentioned signal system 300 includes a limiting triangle A331 fixed on the motherboard 100, and the left and right sides of the limiting triangle A331 are provided with two swinging triangles 332 of symmetrical design, and the two swinging triangles 332 can only realize the limiting rotation function on the motherboard 100. In this embodiment, the limiting rotation function of the swinging triangle 332 is specifically realized by its own two sides of different lengths, such as Figure 2 As shown, the long sides of the two swing triangles 332 are adjacent to the chamfer of the limiting triangle A331, and the short sides are adjacent to the signal triangle 310. Due to the limitation of the signal triangle 310, the swing triangle 332 can only reciprocate in the direction of the limiting triangle A331. The elastic sinker 700 can match the left / right action of the head of the flat knitting machine accordingly through the design of the swing triangle 332.

[0033] Furthermore, the above-mentioned skateboard 200 is also formed with a guide groove 201. The guide groove 201 adopts a Z-shaped design combining an upper groove area 211 and a lower groove area 221, and is transitioned with an arc structure at the connection point. The upper groove area 211 and the lower groove area 221 correspond to the working position and the zero position respectively. A slider 110 is installed in the longitudinal groove 101 set in the above-mentioned motherboard 100. The front end of the slider 110 is combined with the signal triangle 310, and the rear end is combined with a bottom plate 340 equipped with a guide wheel 350 (which can also be a bearing or other similar components). The guide wheel 350 of the bottom plate 340 is located in the guide groove 201 of the skateboard 200; when the skateboard 200 is driven by the driving element to slide left and right, the cooperation between the guide groove 201 and the guide wheel 350 can make the signal triangle 310 move up and down accordingly. At the same time, the left and right sliding distance of the skateboard 200 is also limited by the abutment between the guide wheel 350 and the guide groove 201.

[0034] Specifically, the guide groove 201 of the above-mentioned slide plate 200 can be further processed into an extended groove area 231. The height of the extended groove area 231 is slightly higher than the upper groove area 211, and the connection between the two also adopts an arc structure for transition. In simple terms, when the guide wheels 350 of the left and right groups of signal devices of the machine head are located in the extended groove area 231 at the same time, the elastic sinkers 700 of the two groups of signal devices will cross each other.

[0035] Furthermore, the installation method of the above-mentioned slide plate 200 is realized by the front and rear combined fixing seat 400 and the slide plate seat 500; Figure 4-Figure 5 As shown, the back side of the skateboard seat 500 is formed with protruding portions 501 on the upper and lower sides, and a horizontal limiting groove 502 is formed between the two protruding portions 501. The skateboard 200 is installed behind the skateboard seat 500 through the limiting groove 502. The strip-shaped avoidance groove 202 is used to allow the protruding portions 501 above the skateboard seat 500 to pass through. The fixed seat 400 is located on the other side of the skateboard 200. It is spliced ​​with the protruding portions 501 on the upper and lower sides of the skateboard seat 500, so that the limiting groove 502 of the skateboard seat 500 is enclosed to form a clamp. The skateboard 200 can only slide left and right in the clamp due to the drive, and will not detach outward.

[0036] Furthermore, a rack 600 is fixed to the back of the above-mentioned skateboard 200, and the rack 600 cooperates with the driving element to pull the skateboard 200 to slide left and right. The driving element can be a cylinder, a motor or other similar components (not shown in the figure). Example

[0037] like Fig. 9As shown: The difference from Example 1 is that the above-mentioned limiting device 330 includes a limiting triangle B333 fixed on the motherboard 100 and formed with a slot, and a sliding triangle 334 is clamped in the slot. The sliding triangle 334 can be pushed by the needle butt 701 of the elastic sinker 700 and slide in a straight line along the slot until it is stopped by the signal triangle 310. Of course, the sliding triangle 334 can also realize the sliding function by itself by connecting the driving element.

[0038] The operating principle of this design is roughly the same as that of the existing signal device. In simple terms, the signal triangle and the needle butt of the elastic sinker are driven to cooperate to extend or retract the elastic sinker, so that it participates in / does not participate in the corresponding yarn pressing work.
