This application also relates to a warp knitting machine having this yarn guide comb device. In this invention, by providing a baffle structure within the yarn guide comb device, the baffle structure is used to drive the corresponding yarn guide needle within the yarn guide comb device to switch to an intermediate position, so that the yarn guide needle of the yarn guide comb device has a left position, a middle position, and a right position. When the baffle structure is used to drive the corresponding yarn guide needle within the yarn guide comb device to switch to the middle position, the stitch length compensation part abuts against at least a portion of the yarn guide needle, so that the stitch length compensation part is disposed within a first gap between the main body and the yarn guide needle, thereby maintaining accurate stitch length without deviation when the yarn guide needle is in the middle position.

Description

Technical Field

[0001] This invention relates to the field of warp knitting machines, and in particular to a yarn guide comb device and a warp knitting machine having the yarn guide comb device. Background Technology

[0002] Jacquard guide needles, with their ability to independently shift each needle, offer irreplaceable advantages in warp-knitted fabric pattern design. Existing Jacquards are typically piezoelectric Jacquards with two shift positions (these two-position piezoelectric Jacquards are dual-station Jacquards), with traditional two-needle, three-needle, and four-needle needle selection technologies. These Jacquards only allow for back-of-needle lateral movement, resulting in three types of yarn-laying motions. By adding front-of-needle lateral movement, the new three-needle and new four-needle technologies can achieve 16 types of yarn-laying motions.

[0003] In the needle selection technology of three-station Jacquard, 36 different Jacquard structures are obtained under different odd and even rows and different control signals. Chinese invention patent (application number: 202110903323.1, publication number: CN113789605B) discloses a method for weaving warp-knitted jacquard products using three-station Jacquard. In order to produce this warp-knitted jacquard product, three-station Jacquards need to be installed on the warp knitting machine.

[0004] A baffle structure is installed in the yarn guide combing device. The baffle structure drives the corresponding yarn guide needle in the yarn guide combing device to switch to the middle position, thereby increasing the number of positions for the yarn guide needle. However, in actual use, there are still the following shortcomings: The tail of the yarn guide needle is provided with a comb holding end. The width of the currently used yarn guide needle is smaller than the width of the comb holding end. This results in a second protrusion on the rear part of the yarn guide needle due to the comb holding end. As a result, there is a first gap between the baffle structure and the yarn guide needle. The yarn guide needle may swing towards the direction of the first gap due to the tension of the yarn, which leads to inaccurate needle spacing. Summary of the Invention

[0005] The present invention provides a yarn guide comb device and a warp knitting machine having the yarn guide comb device. Its main purpose is to overcome the defect of existing multi-station Jacquard knitting machines where a first gap exists between the yarn guide needle and the baffle structure, resulting in inaccurate needle spacing of the corresponding yarn guide needle.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A yarn guide comb device includes a baffle structure and a yarn guide needle. The baffle structure is used to drive the corresponding yarn guide needle to switch to an intermediate position. The baffle structure includes a main body, a bending actuator, and a stitch length compensation part. The bending actuator is used to drive the main body to reciprocate, and the front part of the bending actuator is connected to the rear part of the main body. The stitch length compensation part is disposed on a portion of the main body. When the baffle structure drives the yarn guide needle corresponding to the stitch length compensation part to switch to the intermediate position, the stitch length compensation part abuts against at least a portion of the yarn guide needle, so that the stitch length compensation part is disposed in a first gap between the main body and the yarn guide needle, thereby maintaining the stitch length of the yarn guide needle.

[0008] Furthermore, a portion of the stitch length compensation part is provided with at least one first protrusion, and another portion of the stitch length compensation part is provided with at least one first recess. The first protrusion is located at the front end of the first recess and is connected to the first recess as a whole. When the yarn guide needle corresponding to the stitch length compensation part is switched to the intermediate position, the first protrusion fills the space between the main body and the yarn guide needle, and the second protrusion of the comb holding end on the tail of the yarn guide needle is adapted to be accommodated in the first recess.

[0009] Furthermore, a second recess is provided on the other side of the main body, and the second recess is disposed opposite to the stitch spacing compensation part.

[0010] Furthermore, a portion of the main body is configured as the front part of the main body, and the stitch spacing compensation part is laminated on the front part of the main body by welding or gluing.

[0011] Furthermore, the yarn guide needle has three or four stations, wherein there is a needle spacing between every two adjacent stations.

[0012] Furthermore, the needle pitch of the guide needle is T, where T = needle bed unit length L / machine size E.

[0013] Furthermore, the yarn guide comb device is also equipped with at least one base, a plurality of second piezoelectric ceramic elements spaced apart on the base, and a plurality of front teeth spaced apart on the front part of the base. A plurality of baffle structures are spaced apart on the base, and the lower part of the baffle structure extends into the limiting space between two front teeth belonging to the baffle structure. Each yarn guide needle is equipped with at least one baffle structure and at least one front tooth. Each second piezoelectric ceramic element has a comb holding end on its front part, and each comb holding end has a yarn guide needle adaptedly installed on its front part.

[0014] Furthermore, a second recess is provided on the other side of the main body, and the opening of the second recess is positioned toward the side of the corresponding front tooth, so that a second gap is left between the second recess and the corresponding front tooth.

[0015] Furthermore, the baffle structure can be alternatively mounted on a Jacquard actuator, which is used to drive the corresponding piezoelectric ceramic plate to oscillate.

[0016] A warp knitting machine, characterized in that the warp knitting machine has at least one yarn guide comb device, wherein the yarn guide comb device is the yarn guide comb device mentioned above.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention has a simple structure and strong practicality. By setting a baffle structure in the yarn guide comb device, the baffle structure is used to drive the yarn guide needle corresponding to the stitch length compensation part to switch to the middle position, so that the yarn guide needle has a left position, a middle position and a right position. When the baffle structure is used to drive the corresponding yarn guide needle to switch to the middle position, the stitch length compensation part abuts against at least a part of the yarn guide needle, so that the stitch length compensation part is arranged in the first gap between the main body and the yarn guide needle, thereby keeping the stitch length accurate and not deviating when the yarn guide needle is in the middle position.

[0030] Reference Figure 1 and Figure 2 The yarn guide comb device includes a yarn guide needle 12, at least one base 10, a plurality of second piezoelectric ceramic elements 24 spaced apart on the base 10, a plurality of baffle structures 13 spaced apart on the base 10, and a plurality of front teeth 14 spaced apart on the front of the base 10. The needle pitch of the yarn guide needle 12 is T, where T = needle bed unit length L / machine size E.

[0031] Reference Figure 1 and Figure 2 The baffle structure 13 includes a main body 16, a bending actuator 17, and a stitch length compensation unit 18. The baffle structure 13 is used to drive the yarn guide needle 12 corresponding to the stitch length compensation unit 18 to switch to the intermediate position.

[0032] Reference Figure 1 and Figure 2The bending actuator 17 drives the main body 16 to reciprocate. The front part of the bending actuator 17 is connected to the rear part of the main body 16. When the power terminal of the bending actuator 17 is energized, the first piezoelectric ceramic element of the bending actuator 17 drives the main body 16 to swing. The stitch length compensation part 18 is disposed on a part of the main body 16. In this embodiment, when the baffle structure 13 drives the guide needle 12 corresponding to the stitch length compensation part 18 to switch to the intermediate position, the stitch length compensation part 18 abuts against at least a part of the guide needle 12, so that the stitch length compensation part 18 is disposed in the first gap between the main body 16 and the guide needle 12, thereby maintaining the stitch length of the guide needle 12.

[0033] Reference Figure 1 and Figure 2 By setting a baffle structure 13 in the yarn guide comb device, the baffle structure 13 is used to drive the yarn guide needle 12 corresponding to the needle pitch compensation part 18 to switch to the middle position, so that the yarn guide needle 12 has a left position, a middle position and a right position.

[0034] Reference Figure 3 and Figure 4 In another embodiment, the left station can be configured as the first station, the middle station can be configured as the second station, and the right station can be configured as the third station.

[0035] Reference Figure 1 and Figure 2 In another embodiment, the yarn guide comb device can be configured as a three-station Jacquard device. When the baffle structure 13 is used to drive the yarn guide needle 12 corresponding to the stitch length compensation part 18 to switch to the middle station, the stitch length compensation part 18 abuts against at least a part of the yarn guide needle 12, so that the stitch length compensation part 18 is arranged in the first gap between the main body 16 and the yarn guide needle 12, thereby keeping the stitch length of the yarn guide needle 12 accurate and not deviating when it is in the middle station.

[0036] Reference Figure 1 and Figure 2 At least one first protrusion 47 is provided on a part of the stitch length compensation part 18, and at least one first recess 20 is provided on another part of the stitch length compensation part 18. The first protrusion 47 is located at the front end of the first recess 20 and is connected to the first recess 20 as a whole. When the yarn guide needle 12 corresponding to the stitch length compensation part 18 is switched to the intermediate station, the first protrusion 47 fills the space between the main body part 16 and the yarn guide needle 12. The second protrusion 21 of the comb holding end 23 on the tail of the yarn guide needle 12 is adapted to be accommodated in the first recess 20.

[0037] Reference Figure 1 and Figure 2By setting the first protrusion 47 and the first recess 20, when the guide needle 12 corresponding to the stitch length compensation part 18 is switched to the intermediate position, the first protrusion 47 fills the space between the main body 16 and the guide needle 12. The second protrusion 21 of the comb holding end 23 on the tail of the guide needle 12 is adapted to be accommodated in the first recess 20 of the stitch length compensation part 18. This allows the stitch length compensation part 18 to be well set in the first gap between the main body 16 and the guide needle 12, so as to eliminate the influence of the second protrusion 21 of the comb holding end 23 on the stitch length, thereby maintaining the accuracy of the stitch length of the guide needle 12 and ensuring that the stitch length is accurate and does not deviate.

[0041] Reference Figure 1 and Figure 2 The lower part of the baffle structure 13 extends into the limiting space between two front teeth 14 belonging to the baffle structure 13. Each guide needle 12 is provided with at least one baffle structure 13 and at least one front tooth 14 on both sides. Each second piezoelectric ceramic element 24 is provided with a comb holding end 23 on the front part. Each comb holding end 23 is fitted with a guide needle 12 on the front part.

[0042] Reference Figure 1 and Figure 2In another embodiment, a second recess 22 is provided on the other side of the main body 16. The opening of the second recess 22 is oriented toward the corresponding front tooth 14, so that a second gap 42 is left between the second recess 22 and the corresponding front tooth 14. By providing the second recess 22 on the other side of the main body 16 and opposite to the needle pitch compensation part 18, a second gap 42 is left between the baffle structure 13 and the corresponding front tooth 14 in the three-station piezoelectric Jacquard, so as to improve the stress condition of the piezoelectric ceramic sheet in the second piezoelectric ceramic element 24, thereby extending the service life of the piezoelectric ceramic sheet in the piezoelectric bending actuator 17.

[0043] Example 2, refer to Figure 1 and Figure 2 The difference between this second embodiment and the first embodiment is that the baffle structure 13 is replaceably mounted on the Jacquard driver 41 in the yarn guide comb device. The Jacquard driver 41 can be used to drive the piezoelectric ceramic sheet in the corresponding second piezoelectric ceramic element 24 to swing and the piezoelectric ceramic sheet in the first piezoelectric ceramic element to swing, respectively. The Jacquard driver 41 is detachably mounted on the rear of the base 10.

[0044] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

The lower part of the baffle structure 13 extends into the limiting space 15 between two front teeth 14 associated with the baffle structure 13. Each yarn guiding needle 12 is equipped with at least one baffle structure 13 and at least one front tooth 14. The yarn guiding needle 12 has a left working position, a middle working position, and a right working position. The front end of the yarn guiding needle 12 extends toward the side away from the front teeth 14.

[0046] Reference Figure 1 and Figure 2 The main body 16, the first recess 20, the stitch length compensation part 18, and the second recess 22 are integrated. When the baffle structure 13 is disposed in the yarn guide comb device, the opening of the first recess 20 is positioned towards the comb grip end 23, the stitch length compensation part 18 is positioned on the main body 16 towards the yarn guide needle 12, and the second recess 22 is positioned on the main body 16 towards the front teeth 14 of the yarn guide comb device. A second piezoelectric ceramic element 24 is disposed on the tail of the comb grip end 23. When the second piezoelectric ceramic element 24 is energized, it drives the comb grip end 23 to swing left and right by oscillation.

[0047] Reference Figure 1 and Figure 2 The thickness of the stitch spacing compensation part 18 is 0.1 to 0.15 mm. The stitch spacing compensation part 18 is made of one of the following materials: stainless steel, metal, alloy, magnesium-aluminum alloy, magnesium alloy, aluminum alloy, or resin.

[0048] Reference Figure 1 and Figure 2 The main body 16 is made of one of the following materials: stainless steel, metal, alloy, magnesium-aluminum alloy, magnesium alloy, aluminum alloy, or resin.

[0049] Reference Figure 1 and Figure 2 The bending actuator 17 includes an insulating first substrate 31 and two piezoelectric ceramic sheets 30 respectively wrapped around both sides of the first substrate 31. The tail of the piezoelectric ceramic sheet 30 is provided with a first conductive contact 32 to achieve electrical connection. The first substrate 31 is made of fiberglass steel sheet material.

[0050] Reference Figure 1 and Figure 2 The second piezoelectric ceramic element 24 includes an insulating second substrate and two second piezoelectric ceramic sheets respectively wrapped around both sides of the second substrate. A second conductive contact is provided at the tail of each second piezoelectric ceramic sheet to achieve electrical connection. The second substrate is made of fiberglass steel sheet.

[0051] Fiberglass sheets, also known as glass fiber reinforced plastic sheets, are products made by pre-impregnating glass fiber yarn with styrene-based polyester resin and then pultruding it through heating and curing. They can also be called glass fiber sheets or glass fiber plates. Two piezoelectric ceramic sheets, respectively disposed on both sides of the first substrate 31, constitute the first piezoelectric ceramic portion. Two piezoelectric ceramic sheets, respectively disposed on both sides of the second substrate, constitute the second piezoelectric ceramic portion.

[0052] In another embodiment, the plurality of first piezoelectric ceramic portions and the plurality of second piezoelectric ceramic portions are arranged at equal intervals.

[0053] The needle spacing is T, where T = needle bed unit length L / machine size E.

[0054] The unit length L of the needle bed is 25.4 mm in imperial units, and 30 mm for the Z303 warp knitting machine.

[0055] Table 1. Relationship between machine size and needle pitch

[0056] Different models of yarn guide combs, such as E24, E22, and E18, have different stitch pitches for these types of jacquard: E24 = 1.058mm, E22 = 1.154mm, and E18 = 1.811mm. E24 means there are 24 stitches per inch. Since 1 inch = 25.4mm, the stitch pitch for E24 is 25.4 / 24 = 1.058mm; for E22, it's 25.4 / 22 = 1.155mm; and for E18, it's 25.4 / 18 = 1.411mm.

[0057] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0058] Example 4, refer to Figure 1 and Figure 2 The difference between this fourth embodiment and the first embodiment is that a part of the main body 16 is configured as the front part of the main body 16, and the stitch spacing compensation part 18 is stacked on the front part of the main body 16, and the stitch spacing compensation part 18 has a convex shape.

[0059] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0060] Example 5, refer to Figure 1 and Figure 2 The difference between this fifth embodiment and the first embodiment is that the baffle structure 13 is replaceably mounted on the conductive connector 40 within the yarn guide comb device. Preferably, this connector is the connector 40 of the Jacquard driver 41.

[0061] Reference Figure 1 and Figure 2 In this embodiment, the specific connector 40 can be configured as a plug-in element. The baffle structure 13 is replaceably mounted on the plug-in element in the yarn guide comb device. The baffle structure 13 is replaceably mounted on the plug-in element in the yarn guide comb device by plugging and unplugging.

[0062] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0063] Example 6, refer to Figure 1 and Figure 2 The difference between this sixth embodiment and the first embodiment is that the main body 16 is composed of a first outer piece 43, an inner piece 44 and a second outer piece 45. In this embodiment, the first protrusion 47 is specifically configured as an adjustment piece.

[0064] Reference Figure 1 and Figure 2 The first outer piece 43, the second outer piece 45, and the inner piece 44 together form a complete melon seed chip structure.

[0065] Reference Figure 1 and Figure 2 Inner sheet 44: connects the first outer sheet 43 and the second outer sheet 45, providing a cavity space for connecting the piezoelectric ceramic sheet 30.

[0066] Reference Figure 1 and Figure 2 The second outer piece 45 has an extended stop portion 46 for installing an adjustment plate and for positioning the yarn guide needle 12.

[0067] Reference Figure 1 and Figure 2 Adjusting tab: Used to adjust the needle spacing. When the needle spacing of the guide needle 12 is different, the thickness of the adjusting tab will change.

[0068] Reference Figure 1 and Figure 2 The second outer piece 45 extends outward in structure to provide a position for installing the adjustment piece. The adjustment piece is used to position the spacing of the yarn guide needle 12, and its shape matches the shape of the front tooth 14 of the base 10.

[0069] Reference Figure 1 and Figure 2 The inner sheet 44, the second outer sheet 45, and the first outer sheet 43 are welded together to form a whole. 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 whole is formed, a cavity 50 is formed at the tail of the whole, and the piezoelectric ceramic sheet 30 is bonded together in the cavity 50.

[0070] Reference Figure 1 and Figure 2 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 as needed.

[0071] Reference Figure 1 and Figure 2 The first outer piece 43 and the second outer piece 45 must have a head-blocking part 46 on at least one side, and the position is not limited to... Figure 2 As shown, in another embodiment, the first outer sheet 43 may not extend and the second outer sheet 45 may extend; in another embodiment, both may extend.

[0072] Reference Figure 1 and Figure 2 The thickness of the adjusting plate depends on the required needle spacing. Needle spacing refers to the needle pitch.

[0073] Reference Figure 1 and Figure 2The baffle structure 13 is composed of a first outer piece 43, an inner piece 44, a second outer piece 45, and an adjustment piece stacked in sequence. After being pressed together, they are assembled into a whole by welding or gluing. Then, they are assembled together with the piezoelectric ceramic sheet by gluing to form a whole.

[0074] Reference Figure 1 and Figure 2 In another embodiment, at least one sheet extends outward by a stop portion 46 compared to the other sheets. The sheet can be one of the first outer sheet 43, the inner sheet 44, or the second outer sheet 45.

[0075] Reference Figure 1 and Figure 2 The first outer piece 43 is provided with at least one positioning hole 51, the second outer piece 45 is provided with at least one positioning hole 52, and the inner piece 44 is provided with at least one positioning hole 53. During the stacking process, the positioning holes (positioning holes 51, 52, and 53) are used as a reference to align each positioning hole (positioning hole 51, 52, and 53) with each other, so that the first outer piece 43, the inner piece 44, the second outer piece 45, and the adjusting piece are stacked together more neatly.

[0076] Reference Figure 1 and Figure 2 In another embodiment, a stop portion 46 is provided on the front part of the first outer piece 43, and an adjustment piece is provided on the stop portion 46.

[0077] Reference Figure 1 and Figure 2 In another embodiment, a stop portion 46 is provided on the front part of the second outer piece 45, and an adjustment piece is provided on the stop portion 46.

[0078] Reference Figure 1 and Figure 2 In another embodiment, a stop portion 46 is provided on the front part of the inner sheet 44, and an adjustment piece is provided on the stop portion 46.

[0079] Reference Figure 1 and Figure 2 When the needle pitch of the yarn guide needle 12 is different, the thickness of the adjusting plate will change. The different needle pitch here refers to different models of yarn guide comb devices, such as 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.

[0080] Reference Figure 1 and Figure 2The following explanation, using E24 as an example, illustrates why an adjusting tab is necessary: ​​When the yarn guide needle 12 is in the second station, the measurement must begin from the vertical center line of the yarn guide needle 12. The left stop is the front tooth 14 of the base 10, which is fixed (for simplicity, we'll use a 1.058mm interval, determined by the length of the yarn guide needle 12; let's assume it's 1.058mm). First, without the adjusting tab, removing it significantly increases the stitch length on the right. Normally, both sides should be the same length, 1.058mm, but because there's no adjusting tab on the right, the stitch length (1.058mm) cannot be achieved.

[0081] Reference Figure 1 and Figure 2 The piezoelectric ceramic sheets 30 are arranged at equal intervals. To achieve equal spacing, the outer sheet is thickened first, which can make the left and right spacing equal. The tail of the guide needle 12 is provided with a comb holding end 23. The width of the existing guide needle 12 is smaller than the width of the comb holding end 23. This results in a second protrusion 21 on the rear part of the guide needle 12 due to the comb holding end 23. This creates a first gap between the baffle structure 13 and the guide needle 12. The second protrusion 21 of the comb holding end 23 of the guide needle 12 will interfere with one side of the baffle structure in the second working position. The guide needle 12 may swing towards the first gap due to the tension of the yarn, which leads to inaccurate needle spacing of the guide needle 12.

[0082] Reference Figure 1 and Figure 2 When the guide needle 12 and the baffle structure 13 are close together at the intermediate station, the intermediate station is not yet blocked, which will cause the intermediate station to be inaccurate in position. Therefore, to solve this problem, the rear part of the thickest baffle is removed, leaving only the front part, which solves the interference problem. After cutting off the excess part, it becomes a shape that is thicker at the front and thinner at the back, with a step at the front. If this structure were a single piece, it would be thicker at the front and thinner at the back, requiring additional processing (it cannot be integrally formed), which would greatly increase the cost. Therefore, the front step is separated, which is the origin of the adjusting plate. This step can be in a raised shape.

[0083] Reference Figure 1 and Figure 2When the needle pitch is a fixed value, such as E24 = 1.058 mm, the thickness of the adjusting plate is also fixed, assuming other dimensions of the base 10 are fixed. If any adjustment is made, the thickness of the adjusting plate must also be adjusted to ensure equal needle pitch on both sides. There is a small second gap 42 between the right side of the baffle structure 13 and the base 10. This second gap 42 allows the second piezoelectric ceramic sheet to swing slightly to the right, improving the stress condition of the second ceramic sheet. If this second gap 42 increases or decreases, the thickness of the adjusting plate must also increase or decrease accordingly.

[0084] Reference Figure 1 and Figure 2 In another embodiment, when the model of the yarn guide comb device is different, for example, E18=1.411mm, the thickness of the adjusting plate can be different from that of E24=1.058mm.

[0085] Reference Figure 1 and Figure 2 In another embodiment, the entire baffle structure 13 consists of four parts, and its thickness affects the processing size of the front teeth 14 of the yarn guide comb device 10. Different models of yarn guide comb devices 10 only need to adjust the adjusting plate to keep the other three pieces (first outer piece 43, second outer piece 45, and inner piece 44) consistent in thickness size, unaffected by the needle pitch.

[0086] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0102] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0103] Example 8, refer to Figure 1 , Figure 2 and Figure 5The difference between Embodiment 8 and Embodiment 1 is that the yarn guiding comb device has two torque adjusters 61, a limiting part 62, at least one base 10, a plurality of yarn guiding needles 12 spaced apart on the base 10, at least two baffle structures 13 spaced apart on the base 10, and a plurality of front teeth 14 spaced apart on the front part of the base 10.

Each yarn guiding needle 12 is equipped with at least one baffle structure 13 and at least one front tooth 14. In this embodiment, the specific yarn guiding comb device is a four-station Jacquard. The yarn guiding needle 12 of the four-station Jacquard has four stations, namely the first station, the fourth station, the second station, and the third station.

[0104] Reference Figure 5 Multiple front teeth 14 are arranged at intervals on the front part of the base 10, and a first station, a fourth station, a second station and a third station are arranged between two front teeth 14.

[0105] Reference Figure 5 Multiple limiting parts 62 are arranged at intervals on the front of the base 10. The limiting parts 62 are adapted between the two front teeth 14. The limiting parts 62 are equipped with a second station and a fourth station. The fourth station and the second station are respectively arranged at intervals on the left and right sides of the limiting parts 62. The first station, the fourth station, the second station and the third station are arranged sequentially along the movement direction of the yarn guide needle 12.

[0106] Reference Figure 5 The yarn guide needle 12 switches positions between the first station, the fourth station, the second station, and the third station.

[0107] Reference Figure 5 One baffle structure 13 is positioned between the second and third workstations, and is used to drive the corresponding yarn guide needle 12 from the third workstation to the second workstation. Another baffle structure 13 is positioned between the first and fourth workstations, and is used to drive the corresponding yarn guide needle 12 from the first workstation to the fourth workstation. When one baffle structure 13 switches to the second workstation, another part of the baffle structure 13 is connected to another part of a torque adjuster 61, thereby increasing the torque of the baffle structure 13. When the other baffle structure 13 switches to the fourth workstation, another part of the other baffle structure 13 is connected to another part of another torque adjuster 61, thereby increasing the torque of the other baffle structure 13.

[0108] Reference Figure 5The torque adjuster 61 has a magnetic unit. A baffle structure 13 has at least one contact portion adapted to the magnetic unit. When one baffle structure 13 switches to the second position, the contact portion of one baffle structure 13 is attracted by a magnetic unit to the side of the limiting part 62 facing the second position.

[0109] Reference Figure 5 In this embodiment, the yarn guide comb device is a four-station Jacquard. The yarn guide needles 12 switch positions between the first station, the fourth station, the second station, and the third station. The first station and the fourth station are separated by one needle length, the fourth station and the second station are separated by one needle length, and the third station and the second station are separated by one needle length.

[0110] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0111] Example 9, referring to Figure 6 and Figure 7 The difference between Embodiment Nine and Embodiment One is that the yarn guiding comb device includes a Jacquard comb 120, a processor 112, a first interface 110, a second interface 111, a main controller 113, and a communication bus 114. The processor 112 can be an MCU microcontroller. The Jacquard comb can be a wired Jacquard, a wireless Jacquard, a wired piezoelectric Jacquard, a wireless piezoelectric Jacquard, a wired piezoelectric ceramic Jacquard, or a wireless piezoelectric ceramic Jacquard. The yarn guiding needles 12 provided inside the Jacquard comb 120 have a first station, a second station, and a third station.

[0112] Reference Figure 6 and Figure 7The processor 112 is integrated into the Jacquard comb 120. A first interface 110 is located on one side of the Jacquard comb 120, and a second interface 111 is located on the other side. The main controller 113 sends process data to the Jacquard comb 120 so that the Jacquard comb 120 completes the jacquard operation after being powered on. The main controller 113 is electrically connected to multiple Jacquard combs 120 via a communication bus 114. The second interface 111 of one Jacquard comb 120 is electrically connected to the first interface 110 of another adjacent Jacquard comb 120, thus allowing multiple Jacquard combs 120 to be arranged together. When the yarn guide comb device is powered on... When processor 112 is not assigned a corresponding communication address, processor 112 does not respond. When the master controller 113 does not receive feedback from processor 112, the master controller 113 continuously queries the communication address status of processor 112. When processor 112 detects a communication address setting signal on the first interface 110 and processor 112 is not assigned a corresponding communication address, processor 112 sets the address value currently queried on the communication bus 114 as the first communication address of processor 112. Processor 112 responds to the query of master controller 113 with the first communication address as the corresponding communication address status of processor 112. The communication address setting signal can be configured as a high-level signal.

[0113] Reference Figure 6 and Figure 7 In this embodiment, the automatic address encoding function is bidirectional, meaning that input can be made to both sides of the Jacquard comb (first interface 110 or second interface 111). The processor 112 (MCU) will automatically detect the direction. Sometimes, when the Jacquard comb is installed, it is installed face to face, and the Jacquard signal input direction is opposite. However, it is required that the communication address of the Jacquard comb on the same side be consistent. Therefore, this feature will bring great convenience to the application of Jacquard comb.

[0114] Reference Figure 6 and Figure 7 When the main controller 113 is located on one side of the first jacquard comb 121, specifically on the left side of the first jacquard comb 121 in this embodiment, the communication address setting signal is input from the left, with the address encoding direction from left to right. The communication address setting signal output by the main controller 113 enters through the first interface 110 of the first jacquard comb 121, thereby causing the second interface 111 of the first jacquard comb 121 to output the communication address setting signal to the second interface 111 of the adjacent jacquard comb 120. When the processor 112 of a jacquard comb 121 detects that there is a communication address setting signal input on the first interface 110 of the jacquard comb 121, the second interface 111 of the jacquard comb 121 is configured to output the communication address setting signal to the first interface 110 of the adjacent jacquard comb 121.

[0115] Reference Figure 6 , Figure 7 and Figure 8 When the master controller 113 is located on the other side of the first jacquard comb 121, specifically on the right side of the first jacquard comb 121 in this embodiment, the communication address setting signal is input from the right side, and the address encoding direction is from right to left. The communication address setting signal output by the master controller 113 enters through the second interface 111 of the first jacquard comb 121, thereby causing the first interface 110 of the first jacquard comb 121 to output the communication address setting signal to the second interface 111 of the adjacent jacquard comb 120. When the processor 112 of a jacquard comb 121 detects that there is a communication address setting signal input on the second interface 111 of the jacquard comb 121, the first interface 110 of the jacquard comb 121 is configured to output the communication address setting signal to the second interface 111 of the adjacent jacquard comb 120.

[0116] Reference Figure 6 The communication bus 114 includes a power line, an RS485 communication bus, an address signal line, and a pin injection signal line.

[0117] Reference Figure 6 and Figure 7 When the master controller 113 receives the response of the first communication address, it determines that the Jacquard comb 120 corresponding to the first communication address has been encoded and is online. The master controller 113 then sends a query for the second communication address to the second Jacquard comb 122 through the communication bus 114. When the first Jacquard comb 121 receives the query from the master controller 113 by its own address + 1, the second interface 111 of the first Jacquard comb 121 is configured to output a communication address setting signal and sends a communication address setting signal to the first interface 110 of the second Jacquard comb 122.

[0118] Reference Figure 6 and Figure 7 When the processor 112 of the Nth Jacquard 123 is not assigned a corresponding Nth communication address, the processor 112 of the Nth Jacquard 123 does not respond to the query of the master controller 113. When the master controller 113 does not receive feedback from the Nth communication address, the master controller 113 continues to query the communication address status of the processor 112 corresponding to the Nth communication address, where N is a positive integer greater than 1.

[0119] Reference Figure 6 and Figure 7When the processor 112 of the Nth Jacquard Comb 123 detects a communication address setting signal on the first interface 110 and the processor 112 of the Nth Jacquard Comb 123 has not been assigned a corresponding Nth communication address, the processor 112 of the Nth Jacquard Comb 123 sets the address value currently queried by the communication bus 114 as the Nth communication address of the processor 112. The processor 112 responds to the query of the master controller 113 with the Nth communication address as the communication address status corresponding to the processor 112 of the Nth Jacquard Comb 123.

[0120] Reference Figure 6 and Figure 7 When the master controller 113 receives a response for the Nth communication address, it indicates that the Jacquard comb 120 corresponding to the Nth communication address has been encoded and is online. The master controller 113 then sends a query for the Nth communication address to the Nth Jacquard comb 123 via the communication bus 114. When the Nth Jacquard comb 123 receives a query from the master controller 113 at its own address + 1, the second interface 111 of the Nth Jacquard comb 123 is configured to output a communication address setting signal and sends a communication address setting signal to the first interface 110 of the (N+1)th Jacquard comb. This encoding action is repeated, in the order from the first Jacquard comb 121 connected to the connector on the master controller 113 to the Mth Jacquard comb 123, automatically completing the address encoding action. The value of M is the total number of Jacquard combs. The value of the positive integer is in the range of 1 to X, where X is the total number of Jacquard combs - 1.

[0121] The principle behind automatic address encoding in this embodiment is as follows:

[0122] Reference Figure 6 and Figure 7 Step 1: After all the Jacquard combs 120 are arranged, the main controller 113 powers on the Jacquard combs 120.

[0123] Reference Figure 6 and Figure 7 Step 2: After the Jacquard 120 is powered on, all Jacquard 120s are initially in a state without a communication address, that is, the communication address is a fixed value of 0, indicating that the communication address is empty.

[0124] Reference Figure 6 and Figure 7 Step 3: After powering on the Jacquard comb 120, the main controller 113 sets the communication address signal on its own ADDR pin and continuously queries the status of the Jacquard comb 120 with the first communication address on the communication bus. Since all Jacquard combs 120 have no communication address when powered on, they will not send a response to the main controller 113. Therefore, the main controller 113 will continue to query the Jacquard comb 120 with the first communication address until it receives a response from the first communication address.

[0125] Reference Figure 6 and Figure 7 Step 4: After being powered on, Jacquard 120 will automatically and continuously check whether there is a communication address setting signal in both directions of ADDR. When it finds that there is a communication address setting signal in ADDR1 on the left and that it has no address, it will set its own address value according to the address currently queried by 485. Since the master controller 113 is initially querying the first communication address, the first Jacquard 121 will set its own communication address to the first communication address (the first communication address is encoded as 1) and immediately respond to the query of the master controller 113.

[0126] Reference Figure 6 and Figure 7 Step 5: After the master controller 113 receives the response of the first communication address, it indicates that the first Jacquard comb 121 of the first communication address has been encoded and is online. Therefore, it sends a query for the second communication address corresponding to the second Jacquard comb 122 on the communication bus. After receiving the query from the master controller 113 by its own address + 1, the Jacquard comb 120 will set ADDR2 to the output communication address setting signal, that is, send the communication address setting signal to ADDR1 of the second Jacquard comb 122.

[0127] Reference Figure 6 and Figure 7 Step 6: The second Jacquard comb 122 repeats the actions of steps 4 to 5, encodes itself as 2 (the second communication address is encoded as 2), and sends a communication address setting signal to the next Jacquard comb 120. This process is repeated, and the address encoding action is automatically completed from the first Jacquard comb 121 to the Nth Jacquard comb 123 starting from the main controller 113 connector.

[0128] Reference Figure 6 , Figure 7 and Figure 8 Step 7: As can be seen from steps 4 to 6, starting with the first Jacquard comb 121 connected to the main controller 113, the communication address is 1. The encoding function is not unidirectional.

[0129] Reference Figure 8 If the master controller 113 is on the right, the communication address setting signal will enter from the ADDR2 of the rightmost first Jacquard comb 121. The ADDR1 of the first Jacquard comb 121 will output the communication address setting signal to the second Jacquard comb 122 from right to left. The process is the same as 4-6, except that ADDR2 is the input and ADDR1 is the output. Therefore, the encoding direction increases sequentially from right to left. Thus, automatic address encoding can be performed in both left and right directions, which is an important feature of automatic address encoding in this embodiment.

[0130] Reference Figure 6 and Figure 7In this embodiment, by setting a processor 112 on the Jacquard comb 120, when the processor 112 detects a communication address setting signal on the first interface 110 and the processor 112 has not assigned a corresponding communication address, the processor 112 sets the address value currently queried by the communication bus 114 as the first communication address of the processor 112. The processor 112 responds to the query of the master controller 113 with the first communication address as the communication address status of the processor 112, thereby completing the setting of the communication address of the Jacquard comb 120 and achieving the effect of automatic address encoding.

[0131] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0132] Example 10, referring to Figure 6 ,and Figure 7 The difference between this embodiment ten and embodiment one is that the yarn guide comb device includes a Jacquard comb 120, a processor 112, a first interface 110, a second interface 111, and a communication bus 114. The processor 112 is an integrated MCU single-chip microcomputer processor 112 disposed in the Jacquard comb 120.

[0133] Reference Figure 6 and Figure 7 The first interface 110 is located on one side of the Jacquard comb 120. The Jacquard comb 120 receives process data sent by the external master controller 113 through the communication bus 114, so that the Jacquard comb 120 can complete the jacquard action after being powered on. When the yarn guide comb device is powered on and the processor 112 has not been assigned a corresponding first communication address, the processor 112 does not respond. When the processor 112 detects that there is a communication address setting signal on the first interface 110 and the processor 112 has not been assigned a corresponding first communication address, the processor 112 sets the address value currently queried by the communication bus 114 as the first communication address of the processor 112 and the processor 112 responds to the query of the master controller 113.

[0134] Reference Figure 6 and Figure 7 The processor 112 is integrated into the jacquard comb 120. The first interface 110 is located on one side of the jacquard comb 120, and the second interface 111 is located on the other side of the jacquard comb 120. The main controller 113 is used to send process data to the jacquard comb 120 so that the jacquard comb 120 can complete the jacquard action after being powered on. The main controller 113 is electrically connected to multiple jacquard combs 120 through a communication bus 114. The second interface 111 of one jacquard comb 120 is electrically connected to the first interface 110 of another adjacent jacquard comb 120, so that multiple jacquard combs 120 can be arranged together.

[0135] Reference Figure 6 and Figure 7 Multiple jacquard combs 120 are connected in parallel via a communication bus, allowing the processor 112 on each jacquard comb 120 to be individually configured with a communication address.

[0139] Reference Figure 6 Circuit 1: Processor 112 is an MCU circuit. The peripheral circuits of the MCU circuit include a crystal oscillator, memory, and indicator lights. The crystal oscillator provides a suitable clock signal for the MCU. The memory can store relevant data. The indicator lights are tri-color LEDs, displaying different colors to indicate different operating states and alarms.

[0140] Reference Figure 6 and Figure 7Circuit 2: The function of the drive circuit board removal detection circuit 131 is to send an alarm to the processor 112 when it detects that the drive circuit board 130 has been removed and the information does not match that of the Jacquard comb 120. When the drive circuit board removal detection circuit detects that the drive circuit board 130 has been removed, it sends an alarm to the processor 112, and the processor 112 reports the removal of the drive circuit board 130 to the main controller 113 via the communication bus.

[0141] Reference Figure 6 and Figure 7 Circuit 3: Serial communication circuit 132, connected to the communication bus, uses a 1 / 8 unit load RS485 chip. Up to 256 chips can be connected to the communication bus 114, providing a high communication rate. The RS485 chip converts RS485 levels into levels recognizable by the MCU. The Jacquard comb 120's operating status is transmitted in real-time to the main controller 113 via RS485 communication. This operating status includes automatic address setting, high voltage, low voltage, Jacquard leakage current detection, data reception, etc. The processor 112 obtains the Jacquard comb 120's operating status through the serial communication circuit 132. When the processor 112 obtains the Jacquard comb 120's operating status through the serial communication circuit 132, it feeds back the operating status to the main controller 113 via the communication bus.

[0142] Reference Figure 6 and Figure 7 Circuits 4 and 5: Connectors. These connectors are used for power transmission, communication bus signal transmission, time clock signal transmission, and address setting signal transmission. They function as a cascade for approximately 120 Jacquard combs, theoretically allowing for a cascade of up to 256 Jacquard combs.

[0143] Reference Figure 6 and Figure 7 Circuit 6: Power conversion circuit 133, which converts the low voltage of 24V to 3.3V to power circuits 1 and 8.

[0144] Reference Figure 6 and Figure 7 Circuit 7: Leakage current detection circuit 134. The function of leakage current detection circuit 134 is to convert the leakage current of the piezoelectric ceramic sheet into voltage. The processor 112 (MCU) uses this voltage to detect the magnitude of the leakage current of the piezoelectric ceramic sheet. When the value exceeds the set value, the processor 112 (MCU) sends an alarm message to the main controller 113 via RS485.

[0145] Reference Figure 6 Circuit 8: Data output level conversion circuit 135 converts the output voltage level of processor 112 (MCU) into a level that can drive Jacquard high voltage drive circuit 136, while also providing high voltage and low voltage isolation.

[0146] Reference Figure 6 Circuit 9: Jacquard high-voltage drive circuit 136. Jacquard high-voltage drive circuit 136 is used to drive the piezoelectric ceramic sheet, and outputs high voltage to drive the piezoelectric ceramic sheet to swing left and right.

[0147] Reference Figure 6 and Figure 8 Circuit 10, bidirectional address direction detection circuit 151, is electrically connected to processor 112 (MCU) so that when the Jacquard comb is connected, processor 112 can detect the interfaces on both sides of the Jacquard comb (first interface 110 or second interface 111) respectively. That is, both interfaces on both sides of the Jacquard comb can be input, and processor 112 (MCU) will automatically detect the direction.

[0148] Reference Figure 6 and Figure 8 The second piezoelectric ceramic element 24 contains a glass fiber sheet and piezoelectric ceramic sheets wrapped around the left and right sides of the glass fiber sheet. The tail of each piezoelectric ceramic sheet has a terminal with a copper strip, and the front of the piezoelectric ceramic sheet is provided with a guide needle 38. The guide needle 38 is made of stainless steel. The second piezoelectric ceramic element 24 is disposed within the Jacquard comb and is electrically connected to the drive circuit 30.

These conductive contacts are used to transmit communication signals, power, communication address setting signals, and injection signals sent by the main controller 113 to the processor 112, respectively. After receiving the injection signal, the processor 112 drives the piezoelectric ceramic plate to swing through the Jacquard high-voltage drive circuit 136, so that the yarn guide needle 38 can perform jacquard action.

[0152] Although Figure 7 The image only shows three Jacquard combs arranged together, but this does not mean that only three Jacquard combs are used in the actual operation of the warp knitting machine. The number of Jacquard combs can be determined according to the machine number of the warp knitting machine.

[0153] A processor is a circuit capable of processing signals. In one implementation, a processor can be a circuit with instruction read and execute capabilities, such as a central processing unit (CPU), microprocessor, or digital signal processor (DSP). In another implementation, a processor can achieve certain functions through the logical relationships of hardware circuits. These logical relationships can be fixed or reconfigurable. For example, a processor may be a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field-programmable gate array (FPGA). In reconfigurable hardware circuits, the process of the processor loading a configuration file and configuring the hardware circuit can be understood as the processor loading instructions to achieve the functions of some or all of the aforementioned units. Furthermore, a processor can also be a hardware circuit designed for artificial intelligence, which can be understood as a type of ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), or deep learning processing unit (DPU).

[0154] Communication buses can be Peripheral Component Interconnect (PCI) buses or Extended Industry Standard Architecture (EISA) buses, etc. Communication buses can be categorized into address buses, data buses, control buses, etc. For ease of representation, Figure 6 Only one thick line is used in the diagram, but this does not mean that there is only one bus or one type of bus.

[0155] Other structures are similar to those in Embodiment Nine, and will not be described in detail here.

[0156] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
