AI Technical Summary
In existing flat knitting machines with a shaking table needle transfer function, the existing sinker may swing due to the vibration of the needle bed, which may cause the sinker on both sides of the needle bed to overlap laterally and collide with each other at the needle opening.
A sinker with positioning function was designed. The positioning edge has a continuous undulating structure, including a first limit, a second limit, and a third limit. It has elastic deformation capability. The swing of the sinker is restricted by the steel wire limit component in conjunction with the positioning edge, so as to ensure that it is not affected by the vibration of the needle bed under different working conditions.
This makes the sinker more stable during operation, unaffected by needle bed vibration, avoids collisions between sinkers, and improves the working efficiency and reliability of the flat knitting machine.

TECHNICAL FIELD
[0001] The utility model relates to the field of flat knitting machines, in particular to a sinker with positioning function. BACKGROUND
[0002] The sinker is a kind of accessory for flat knitting machine, when used on double needle bed of computer flat knitting machine, it is unfolded along the needle bed mouth part and distributed in the knitting area of needle bed mouth part, by arranging sinker beside each needle, sinker is arranged on spacer, and isolated by spacer, sinker controls old loop and new yarn on each needle, assists needle to drop loop, and can rotate relative to needle bed mouth to open and give out position to form loop.
[0003] The sinker is generally arranged between needles on the needle bed of flat knitting machine, and swings around the needle plate hole side near the needle bed as fulcrum to displace, and the needle butt part (also called driving part) of sinker is driven to realize entering or exiting needle plate hole by cam mechanism arranged on slide and driving push piece.
[0004] The sinker does not have industry standard, so it has various structures according to design ideas of technical personnel and different required functions under the premise of basic functions, such as the sinker with relatively square overall shape involved in WO2022248143A1 Groz-Beckert company, the sinker with return spring involved in CN218507988U Daisen company, and the relatively wide sinker involved in CN202298045U and CN202227057U of Ningbo Cixing company.
[0005] However, the existing sinker has a problem, especially in the flat knitting machine needing swing bed needle shifting function, due to vibration of needle bed, the sinker will swing, which may cause the sinkers on both sides of needle bed to overlap horizontally at needle mouth, and thus collide with each other.
[0006] Therefore, the inventor makes further research and develops a sinker with positioning function, and the case is generated. CONTENT OF UTILITY MODEL
[0007] The utility model aims at providing a sinker with positioning function, which can make the sinker more stable during work.
[0008] In order to achieve the above purpose, the technical scheme of the utility model is as follows:
[0009] A sinker with positioning function, comprising
[0010] Positioning edge, the positioning edge is located at one end of the sinker body, the positioning edge is a continuous undulating structure, which at least includes a first limit, a second limit, a third limit, and has elastic deformation ability;
[0011] Rotary shaft hole, the sinker body swings around the rotary shaft hole as the axis.
[0012] The sinker is generally limited by a limiting piece such as a ruler or a steel wire, and swings around the steel wire as the shaft. However, the existing limiting piece cannot prevent the sinker from swinging due to vibration. Therefore, the sinker itself needs to have a certain "resistance" to prevent displacement due to vibration. Therefore, three limiting positions of the sinker correspond to three working states of the sinker, and the switching is achieved by pushing the sinker heel. The three working states are non-working state, preliminary line pressing state (at this time, the rocking bed is operated, and under ideal conditions, the sinkers on the two needle beds will not collide), and deep line pressing state (at this time, the rocking bed cannot be operated, and the sinkers are transversely overlapped at the needle port). When the sinker heel is not under stress, vibration alone cannot switch the sinker between the limiting positions. When the sinker heel is under stress, the positioning edge has elastic deformation ability, so it does not affect the normal operation of the sinker.
[0013] Further, the positioning edge is a wavy undulating structure, which has at least two wave crests.
[0014] Steel wire is commonly used for the installation of the sinker. Therefore, the wavy positioning edge is adopted to match the steel wire. The wavy structure of the positioning edge and the outer edge of the steel wire can smoothly transition, and will not cause excessive resistance to cause the phenomenon that the sinker heel cannot be pushed.
[0015] Further, the positioning edge is an arc-shaped narrow structure, which has a gap between the sinker body.
[0016] This feature is one of the structures of the positioning edge with elastic deformation.
[0017] Further, the rotary shaft hole is surrounded by a complete through-hole structure.
[0018] This structure is a common structure of the sinker.
[0019] Further, the rotary shaft hole is arranged in the adapter slot of the sinker, the adapter slot is open at the opening, gradually converges towards the inside, and forms the rotary shaft hole therein.
[0020] The rotary shaft hole is formed by "clamping" the two sides of the adapter slot in a strict sense.
[0021] After adopting the above scheme, the present application has the following advantages compared with the prior art:
[0022] The sinker is assisted in knitting by the knitting needle in different positions, and is limited by cooperation of the positioning edge and the positioning member, so that the sinker is not displaced by vibration of the needle bed, that is, the sinker has a more stable working state.

[0026] REFERENCE NUMERALS
[0027] sinker 1, positioning edge 11, sinker heel 12, adapter groove 13,
[0028] first steel wire 2, second steel wire 3, needle bed 4. DETAILED DESCRIPTION
[0029] The present application will be further described below in conjunction with the drawings and specific embodiments.
[0030] As Figure 1 shown, a sinker with a positioning function, one end of the body of the sinker extends from left to right and is provided with a positioning edge 11, the positioning edge 11 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 sinker heel 12, a gap is provided from the sinker heel to the line pressing part, so that the positioning edge 11 has a certain elastic deformation capacity.
[0031] As Figure 2 shown, on the two side flat knitting needle beds 4, a positioning mechanism for the sinker is provided, which further includes a first steel wire 2 and a second steel wire 3 for limiting the sinker 1, wherein when the sinker heel is subjected to a driving force, from the perspective of Figure 2 , the second steel wire is taken as a pivot shaft, and it can swing left and right at the needle opening.
[0032] The part of the positioning edge 11 close to the sinker heel 12 is provided with a continuous wave-shaped undulating structure, which forms a first limit, a second limit and a third limit (also taken as Figure 1 the angle as a reference) from left to right, two wave crests are formed between the three limits, and correspond to the state of the sinker not participating in work (also refer to Figure 2 the left sinker), the state of participating in work and can swing the bed to move the needle (also refer to Figure 2Because the first steel wire is closely attached to the positioning edge 11, only when the heel is pushed by a force will the positioning edge 11 be pressed downward to a certain extent, thereby allowing the first steel wire to switch between the first limit position, the second limit position, and the third limit position. When the heel is not acted upon by a force, the vibration generated by the needle bed itself is not sufficient to push the sinker 1.
[0033] 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 provided inside the adapter groove 13, but the opening of the adapter groove 13 is smaller than the diameter of the second steel wire, and the second steel wire can be inserted or pulled out with a little force.
[0034] The commonly used technical means in the prior art are as follows Figure 3 As shown, a transfer hole is provided below the sinker 1, and the second steel wire is passed into the transfer hole from the side. However, since the sinkers 1 are arranged in a row on the needle bed, the entire steel wire needs to be pulled out to replace a single sinker 1, and the maintenance efficiency is lower than that of the above embodiment.
[0035] At the same time, the positioning of the first steel wire is not limited to steel wire, and other shapes of limiting members can also be used. It is only necessary to modify the shape of the upper side of the positioning edge 11 accordingly.
[0036] 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.
