Description

TECHNICAL FIELD

[0001] The utility model relates to the field of flat knitting machines, in particular to a sinker positioning structure. BACKGROUND

[0002] A sinker is a kind of accessory for flat knitting machines, which is used on double needle beds of computer flat knitting machines. The sinker is arranged beside each needle, and is set on a spacer, isolated from each other by the spacer. The sinker controls the old loops and new yarn on each needle, assists the needle to drop the loops, and rotates relative to the needle bed opening to create a position for looping.

[0003] The sinker is generally arranged between the needles on the needle bed of the flat knitting machine, and swings around the needle plate hole side near the needle bed as a fulcrum. The cam mechanism on the slide carriage drives the push piece to drive the heel of the sinker (also known as the driving part) to enter or exit the needle plate hole.

[0004] There is no industry standard for sinkers, so they have various structures depending on the design ideas of technicians and the required functions, such as the sinker with a relatively square overall shape disclosed in WO2022248143A1 Groz-Beckert GmbH & Co. KG, the sinker with a return spring disclosed in CN218507988U Shimaseiki Co., Ltd., and the relatively wide sinker disclosed in CN202298045U and CN202227057U of Ningbo Cixing Company.

[0005] However, the existing sinkers all have a problem, especially in flat knitting machines that need to perform the swing bed needle shifting function. Due to the vibration of the needle bed, the sinker may swing and cause the sinkers on both sides of the needle bed to overlap horizontally at the needle opening, resulting in collision.

[0006] Therefore, the present inventors have further researched and developed a sinker positioning structure, which has been produced as a result. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims to provide a sinker positioning structure, which can make the work of the sinker more stable.

[0008] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0009] A sinker positioning structure, comprising a sinker, the sinker is arranged along the needle bed mouth part and distributed in the knitting area of the needle bed mouth part, one end of the sinker is provided with a positioning edge;

[0010] The positioning edge is a continuous undulating structure, which at least comprises a first limit, a second limit and a third limit, and has an elastic deformation capacity.

[0011] The positioning member is arranged on the side of the positioning edge.

[0012] When the sinker swings, the positioning member switches among the first limit, the second limit and the third limit.

[0013] The three limits of the sinker correspond to three working states of the sinker, and the switching is achieved by pushing the heel of the sinker, and the three working states are respectively a non-working state, a preliminary line pressing state (at this time, the rocking bed action is performed, and in an ideal state, the sinkers on the two needle beds do not collide), and a deep line pressing state (at this time, the rocking bed action cannot be performed, and the sinkers are transversely overlapped at the needle port), when the heel of the sinker is not subjected to force, the sinker cannot be switched among the limit states only by vibration, and when the heel is subjected to force, since the positioning edge has an elastic deformation capacity, the normal work of the sinker is not affected.

[0014] Further, when the positioning member is a steel wire, the positioning edge is a wave-shaped undulating structure, which at least has two wave crests.

[0015] The steel wire is commonly used for the installation of the sinker, and therefore, the wave-shaped positioning edge is adopted to adapt to the use of the steel wire.

[0016] Further, the positioning edge is an arc-shaped narrow structure, and a gap is left between the positioning edge and the sinker body.

[0017] This feature is one of the structures in which the positioning edge has an elastic deformation capacity.

[0018] Further, the sinker comprises an adapter hole, the swing of the sinker is taken as the adapter hole, and the adapter hole and the positioning edge are located on different sides.

[0019] The steel wire is generally arranged at the adapter hole as a rotating shaft.

[0020] Further, the sinker comprises an adapter groove, the adapter groove is open at an opening, the inside of the adapter groove is gradually contracted, and an arc-shaped structure is formed on the two sides.

[0021] The adapter groove has the same effect as the adapter hole, and the steel wire can be directly inserted from the opening, at this time, the replacement of the single sinker can be achieved without the need of pulling out the steel wire from the adapter holes of all the sinkers.

[0022] After the above scheme is adopted, compared with the prior art, the present application has the following advantages:

[0023] When the sinker is used to assist the knitting of the needle in different positions, the cooperation of the positioning edge and the positioning member limits the displacement of the sinker caused by the vibration of the needle bed, that is, the sinker has a more stable working state.

[0030] The present application will be further described below in combination with the drawings and specific embodiments.

[0031] As Figure 1 shown, the sinker positioning structure is arranged on the needle bed 4 of the flat knitting machine, which mainly comprises a sinker 1 and a first steel wire 2 and a second steel wire 3 for limiting the sinker 1. Figure 1 When the heel of the sinker is subjected to a driving force, the sinker can swing left and right at the needle port with the second steel wire as the pivot, and the specific positioning structure is shown in Figure 2 .

[0032] One end of the sinker 1 is provided with a positioning edge 11, which is an arc-shaped narrow structure. The left side of the positioning edge 11 is a line pressing part, and the right side is a heel 12. A gap is arranged from the heel 12 to the line pressing part, so that the positioning edge 11 has a certain elastic deformation ability.

[0033] The part of the positioning edge 11 close to the heel is provided with a continuous wave-shaped undulating structure, which forms a first limit, a second limit and a third limit from left to right (also taking the angle as a reference). Two wave crests are formed between the three limits, and correspond to the state of the sinker 1 not participating in work (also referring to Figure 2 the left sinker 1), the state of participating in work and can swing bed needle (also referring to Figure 1 the right sinker 1), and the state of participating in work and deep line pressing. Figure 1 Because the first steel wire is arranged close to the positioning edge 11, only when the heel is subjected to a driving force, the positioning edge 11 will be pressed to a certain extent, so that the first steel wire can switch between the first limit, the second limit and the third limit. When the heel is not subjected to a driving force, the vibration of the needle bed itself is not enough to push the sinker 1.

[0034] In the above embodiment, the second steel wire is arranged in the adapter groove 13 below the sinker 1, that is, a space for accommodating the second steel wire is arranged in the adapter groove 13, but the opening of the adapter groove 13 is smaller than the diameter of the second steel wire, so the second steel wire can be inserted or pulled out by slightly applying force.

[0035] However, the common technical means in the prior art is as shown in the drawings, that is, an adapter hole is arranged below the sinker 1, and the second steel wire is arranged into the adapter hole from the side, and since the sinkers 1 are arranged in parallel into a row on the needle bed, the whole steel wire needs to be pulled out for replacing a single sinker 1, so the maintenance efficiency is lower than that of the above embodiment. Figure 3

[0036] Meanwhile, the positioning at the first steel wire is not limited to the steel wire, but other shaped limiting members can also be used, and only the upper side shape of the positioning edge 11 needs to be modified accordingly.

[0037] The above is only a specific embodiment of the present application, and the words such as "upper", "lower", "left", "right", "middle" and the like involved in the present application are only for reference, and are not absolute limitations, and any non-substantial change made by using the present application shall be regarded as an act of infringing the protection scope of the present application.​
