[0087] Reference Figure 4 and Figure 5 , Adjusting sheet: used to adjust the needle position spacing. When the needle spacing of the yarn guide needle 12 is different, the thickness of the adjusting sheet will change.

[0088] Reference Figure 4 and Figure 5The second outer piece 45 is structurally extended outward to provide a position for installing an adjusting piece, and cooperates with the adjusting piece to locate the spacing position of the yarn guide needles 12 , and its shape matches the shape of the front comb teeth 14 of the bottom base 10 .

[0089] Reference Figure 4 and Figure 5 The inner sheet 44, the second outer sheet 45 and the first outer sheet 43 are welded to form a community, and the tail of the inner sheet 44 is shorter than the first outer sheet 43 and the second outer sheet 45, so that after the community is formed, a cavity 50 is formed at the tail of the community, and the piezoelectric ceramic sheet 30 is bonded together in the cavity.

[0090] Reference Figure 4 and Figure 5 The thickness of the first outer sheet 43, the second outer sheet 45, the inner sheet 44 and the adjusting sheet is generally between 0.1 and 1.5 mm and can be selected according to needs.

[0091] Reference Figure 4 and Figure 5 The first outer sheet 43 and the second outer sheet 45 must have at least one side with a stopper portion 46, and the position is not limited to Figure 5 As shown in , it is possible that the first outer sheet 43 is not extended, the second outer sheet 45 is extended, or both are extended.

[0092] The thickness of the adjustment sheet is determined according to the needle spacing requirements. Needle spacing refers to the needle distance.

[0093] Reference Figure 4 and Figure 5 The stopper 13 is formed by stacking a first outer sheet 43, an inner sheet 44, a second outer sheet 45, and an adjusting sheet in sequence, and then pressed together by welding or gluing to form a whole, and then assembled with the piezoelectric ceramic sheet by gluing to form a whole.

[0094] Reference Figure 4 and Figure 5 In another embodiment, at least one of the sheets extends outwardly from the other sheets to form a stopper portion 46. The sheet may be one of the first outer sheet 43, the inner sheet 44, and the second outer sheet 45.

[0095] Reference Figure 4 and Figure 5At least one positioning circular hole 51 is provided on the first outer sheet 43, at least one positioning circular hole 52 is provided on the second outer sheet 45, and at least one positioning circular hole 53 is provided on the inner sheet 44. During the stacking process, the positioning circular holes (positioning circular holes 51, positioning circular holes 52, positioning circular holes 53) are used as a reference to align the positioning circular holes (positioning circular holes 51, positioning circular holes 52, positioning circular holes 53) with each other, so that the first outer sheet 43, the inner sheet 44, the second outer sheet 45 and the adjustment sheet are more neat after being stacked together.

[0096] Reference Figure 4 and Figure 5 In another embodiment, a stopper portion 46 is provided on the front portion of the first outer plate 43 , and the adjusting plate is provided on the stopper portion 46 .

[0097] Reference Figure 4 and Figure 5 In another embodiment, a stopper portion 46 is provided on the front portion of the second outer plate 45 , and the adjusting plate is provided on the stopper portion 46 .

[0098] Reference Figure 4 and Figure 5 In another embodiment, a stopper portion 46 is provided on the front portion of the inner plate 44 , and the adjustment plate is provided on the stopper portion 46 .

[0099] Reference Figure 4 and Figure 5 When the needle pitch of the yarn guide needle 12 is different, the thickness of the adjusting plate will change. The different needle pitches here refer to different types of Jacquard devices, for example, E24, E22, E18, etc. The needle pitches of these types of Jacquard are: E24=1.058mm, E22=1.154mm, E18=1.811mm, and their needle pitches are different.

[0100] Reference Figure 4 and Figure 5 , below, take E24 as an example to explain why the adjustment piece should be added: when the yarn guide needle 12 is in the second station, the position of the second station must be measured from the middle vertical center line position of the yarn guide needle 12, and the left gear is the front comb tooth 14 of the bottom base 10, which is fixed (for the convenience of explanation, directly press 1.058mm interval, this interval is determined according to the length of the yarn guide needle 12. Assume it is 1.058. First of all, if there is no adjustment piece, after removing the adjustment piece, the needle distance on the right side becomes obviously larger. Normally, the left and right sides are required to be the same, both 1.058mm, but because there is no adjustment piece on the right side, the needle distance (1.058mm) cannot be achieved.

[0101] Reference Figure 1 , Figure 4 and Figure 5, the piezoelectric ceramic sheets 30 are arranged in an equidistant manner. When an equidistant is required, the outer sheet is first thickened to achieve equal spacing on the left and right sides. A comb holding end 23 is provided on the tail of the yarn guide needle 12. The width of the existing yarn guide needle 12 is smaller than the width of the comb holding end 23, which makes a part of the rear of the yarn guide needle 12 have a raised portion 21 due to the comb holding end 23, so that there is a first gap between the stopper 13 and the yarn guide needle 12. The raised portion 21 of the comb holding end 23 of the yarn guide needle 12 and one side of the stopper will interfere with each other in the second station. The yarn guide needle 12 may swing toward the direction of the first gap under the influence of the tension of the yarn, which leads to inaccurate needle spacing of the yarn guide needle 12.

[0102] Reference Figure 4 and Figure 5 When the yarn guide needle 12 and the stopper 13 are close together in the middle station, the second station is not blocked yet, which will cause the position of the second station to be inaccurate. So in order to solve this problem, the rear part of the thickest baffle is removed and only the front part is retained, which can solve the interference problem. After cutting off the excess part, it becomes a shape that is thick in the front and thin in the back, with a step in the front. If this structure is a single piece, that is, thick in the front and thin in the back, it will have to be additionally processed (it cannot be formed as one piece). This processing will greatly increase the cost, so the front step is separated, which is the origin of the adjustment piece. The step can be in a convex shape.

[0103] Reference Figure 4 and Figure 5 , when the needle distance is a fixed value, such as E24=1.058mm, then when the other dimensions of the bottom base 10 are fixed, the thickness of the adjusting plate is also fixed. Once there is an adjustment, the thickness of the adjusting plate also needs to be adjusted to ensure that the needle distances on the left and right are equal. For example: There is a small second gap 42 between the right side of the stopper 13 and the bottom base 10. This second gap 42 is to allow the second piezoelectric ceramic plate to swing slightly to the right, which can improve the stress condition of the second ceramic plate. If this second gap 42 becomes larger or smaller, the thickness of the adjusting plate must also become larger or smaller. Finally, when the product is finalized after actual verification, the thickness of the adjusting plate of the same model of jacquard device 10 must be fixed.

[0104] When the model of the jacquard device is different, for example, E18=1.411mm, the thickness of the adjustment plate may be different from E24=1.058mm.

[0105] Reference Figure 4 and Figure 5In another embodiment, the entire stopper 13 is composed of four parts, and its thickness will affect the processing size of the front comb teeth 14 of the jacquard jacquard device 10. Different models of jacquard jacquard devices 10 only need to adjust the adjustment plate to keep the other three plates (the first outer plate 43, the second outer plate 45, and the inner plate 44) consistent in thickness and not affected by the needle distance.

[0106] The other structures are similar to those of the third embodiment and will not be described in detail here.

[0107] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
