Technical Field
[0001] This invention relates to the field of jacquard, and more particularly to a multi-patterned jacquard comb and textile machinery having the jacquard comb. Background Technology
[0002] The invention discloses a method for weaving warp-knitted jacquard products using a three-station jacquard needle selection technique and 36 different jacquard structures obtained under different control signals for odd and even rows. A Chinese invention patent (application number: 202110903323.1, publication number: CN113789605B) discloses a method for weaving warp-knitted jacquard products using a three-station jacquard needle selection technique. To produce this product, a three-station jacquard needle needs to be installed on the textile machinery.
[0003] A stop is set in a multi-station Jacquard, which drives the corresponding guide needle in the multi-station Jacquard to switch to the middle station, thereby increasing the number of stations for the guide needle. However, in actual use, there are still the following shortcomings: in a multi-station Jacquard, the torque of the stop needs to be greater than the torque of the guide needle for the stop to drive the guide needle to switch from the third station to the second station.
[0004] This disclosure provides a jacquard comb with multiple patterns, which enhances the torque of the stop member at the second position so that the stop member can smoothly stop the guide needle at the second position. Summary of the Invention
[0005] The present invention provides a jacquard comb with multiple patterns and a textile machine having the jacquard comb, the main purpose of which is to overcome the defect of insufficient torque when the stop is in the second position.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A multi-pattern jacquard comb includes: a base, front teeth, yarn guide needles, limiting parts, stop members, and a torque adjuster; a plurality of the front teeth are arranged at intervals on the front part of the base, and a first station, a second station, and a third station are provided between two front teeth; the yarn guide needles switch positions between the first station, the second station, and the third station; a plurality of limiting parts are arranged at intervals on the front part of the base, and a limiting part is adapted to be provided between two front teeth, and a second station is disposed on the limiting part, the second station being located at an intermediate position between the first station and the third station; the stop member is disposed at the switching position between the second station and the third station, and the stop member is used to drive the corresponding yarn guide needle to switch to the second station; wherein, when the stop member switches to the second station, another part of the stop member is integrated with a part of the torque adjuster, thereby increasing the torque of the stop member.
[0008] Furthermore, when the stop member switches to the third station, the stop member switches its position towards the side away from the limiting part and the torque adjuster.
[0009] Furthermore, another part of the torque adjuster is disposed within a portion of the limiting portion, and a portion of the torque adjuster is exposed on the side surface of the limiting portion facing the stop member, and a portion of the stop member abuts against the side surface of the limiting portion facing the stop member.
[0010] Furthermore, when the stop member switches to the second working position, another part of the stop member is attached to a part of the torque regulator.
[0011] Furthermore, the torque adjuster has at least one magnetic unit, and the stop member is provided with at least one contact portion adapted to the magnetic unit. When the stop member switches to the second working position, the contact portion is attracted by the magnetic unit to the side of the limiting part facing the second working position. The attraction force of the magnetic unit is less than the torque of the stop member when it switches from the second working position to the third working position.
[0012] Furthermore, the limiting part is provided with an assembly groove, a part of which extends to the inside of the limiting part. An opening on one end of the assembly groove is provided on the side surface of the limiting part facing the stop member. A part of the magnetic unit is fixedly provided in the assembly groove, and another part of the magnetic unit is provided on the opening. When the stop member is switched to the second working position, at least a part of the contact part covers the opening.
[0013] A multi-pattern jacquard comb bar includes: a base, front teeth, yarn guide needles, limiting parts, at least two stop members, and at least two torque adjusters; a plurality of the front teeth are arranged at intervals on the front part of the base, and a first station, a fourth station, a third station, and a second station are provided between two front teeth; the yarn guide needles switch positions between the first station, the fourth station, the third station, and the second station; a plurality of limiting parts are arranged at intervals on the front part of the base, and a limiting part is adaptedly provided between two front teeth; the fourth station and the second station are respectively arranged at intervals on the left and right sides of the limiting part; the first station, the fourth station, the third station, and the second station are arranged sequentially along the movement direction of the yarn guide needles; One of the stop members is positioned between the second and third workstations, and is used to drive the corresponding yarn guide needle from the third workstation to the second workstation. The other stop member is positioned between the first and fourth workstations, and is used to drive the corresponding yarn guide needle from the first workstation to the fourth workstation. When one stop member switches to the second workstation, another part of the stop member is integrated with a part of a torque adjuster, thereby increasing the torque of the stop member. When the other stop member switches to the fourth workstation, another part of the stop member is integrated with a part of another torque adjuster, thereby increasing the torque of the other stop member.
[0014] Furthermore, the torque adjuster has a magnetic unit, and one of the stops is provided with at least one contact portion adapted to the magnetic unit. When one of the stops is switched to the third station, the contact portion of one of the stops is attracted by one of the magnetic units to the side of the limiting portion facing the second station. When another stop is switched to the fourth station, the contact portion of the other stop is attracted by another magnetic unit to the side of the limiting portion facing the fourth station.
[0015] Furthermore, the first station and the fourth station are separated by a stitch distance, the fourth station and the third station are separated by a stitch distance, and the third station and the second station are separated by a stitch distance.

[0018] This invention has a simple structure and strong practicality. By setting a torque regulator, another part of the torque regulator is set inside a part of the limiting part, and a part of the torque regulator is exposed on the side surface of the limiting part facing the stop member. When the stop member is switched to the second station, the other part of the stop member is connected with a part of the torque regulator, thereby enhancing the torque of the stop member in the second station.

[0032] Reference Figure 1 and Figure 2 Multiple limiting parts 62 are arranged at intervals on the front of the base 10. A limiting part 62 is adapted between every two front comb teeth 14. A second station is arranged on the limiting part 62, and the second station is located in the middle position between the first station and the third station.
[0033] Reference Figure 1 and Figure 2 The yarn guide needles 12 switch positions between the first, second, and third workstations, with a needle length distance between the first and second workstations and between the second and third workstations. In this embodiment, when the yarn guide needles 12 have three workstations, the jacquard guide bar is configured as a three-workstation jacquard guide bar.
[0034] Reference Figure 1 and Figure 2 The stop member 13 is positioned between the second and third workstations.

A part of the stop member 13 is integrated with a part of the torque adjuster 61.
[0035] Reference Figure 1 and Figure 2 When the stop member 13 switches to the second position, a portion of the stop member 13 is integrated with a portion of the torque regulator 61, thereby increasing the torque of the stop member 13.

The stop 13 is replaceably mounted on the plug-in element in the multi-station jacquard by plugging and unplugging.
[0087] Other structures are similar to those in Embodiment 3, and will not be described in detail here.
[0088] Example 8, refer to Figure 5 The difference between this embodiment eight and embodiment one 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.
[0089] Reference Figure 4 and Figure 5 The first outer piece 43, together with the second outer piece 45 and the inner piece 44, forms a complete melon seed chip structure.
[0090] Reference Figure 4 and Figure 5 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.
[0091] Reference Figure 4 and Figure 5 The second outer piece 45 has an extended stop portion 46 for installing an adjustment plate and for positioning the yarn guide needle 12.
[0092] Reference Figure 4 and Figure 5 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.
[0093] Reference Figure 4 and Figure 5 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 needles 12, and its shape matches the shape of the front comb teeth 14 of the base 10.
[0094] Reference Figure 4 and Figure 5 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.
[0095] 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 as needed.
[0096] Reference Figure 4 and Figure 5 The first outer piece 43 and the second outer piece 45 must have at least one side with a head-blocking portion 46, and the position is not limited to... Figure 5 As shown, it is possible that the first outer sheet 43 does not extend and the second outer sheet 45 extends, or both extend.
[0097] The thickness of the adjusting plate depends on the required needle spacing. Needle spacing refers to the needle pitch.
[0098] Reference Figure 4 and Figure 5 The stop piece 13 is composed of a first outer piece 43, an inner piece 44, a second outer piece 45, and an adjusting 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.
[0099] Reference Figure 4 and Figure 5 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.
[0100] Reference Figure 4 and Figure 5 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.
[0101] Reference Figure 4 and Figure 5 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.
[0102] Reference Figure 4 and Figure 5 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.
[0103] Reference Figure 4 and Figure 5 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.
[0104] Reference Figure 4 and Figure 5 When the needle pitch of the guide needle 12 is different, the thickness of the adjusting plate will change. The different needle pitch here refers to different models of multi-station Jacquard, 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.
[0105] Reference Figure 4 and Figure 5The following explanation, using E24 as an example, explains why an adjusting tab is needed: 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 comb tooth 14 of the base 10, which is fixed (for ease of explanation, we will directly use a 1.058mm interval, which is determined based on the length of the yarn guide needle 12. Let's assume it's 1.058mm). First, without the adjusting tab, removing it will significantly increase the stitch length on the right side. Normally, the stitch length on both sides should be the same, 1.058mm, but because there is no adjusting tab on the right side, the stitch length (1.058mm) cannot be achieved.
[0106] Reference Figure 4 and Figure 5 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 protrusion 21 on the rear of the guide needle 12 due to the comb holding end 23. As a result, there is a first gap between the stop 13 and the guide needle 12. The protrusion 21 of the comb holding end 23 of the guide needle 12 will interfere with one side of the stop in the second 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.
[0107] Reference Figure 4 and Figure 5 When the guide needle 12 and the stop 13 are close together at the middle station, the second station is not yet blocked, which will cause the position of the second station to be inaccurate. Therefore, to solve this problem, the rear part of the thickest stop piece 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 piece. This step can be in a raised shape.
[0108] Reference Figure 4 and Figure 5When the stitch pitch is a fixed value, such as E24 = 1.058 mm, the thickness of the adjusting plate is also fixed, provided that 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 that the stitch pitches on the left and right sides are equal. For example, there is a small second gap 42 between the right side of the stop 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. Ultimately, after the product has been verified and finalized, the thickness of the adjusting plate for the same model of multi-station Jacquard 10 will be fixed.
[0109] When the multi-station Jacquard models are different, for example, E18=1.411mm, the thickness of the adjusting plate can be different from that of E24=1.058mm.
[0110] Reference Figure 4 and Figure 5 In another embodiment, the entire stop 13 consists of 4 parts, and its thickness affects the processing dimensions of the front comb teeth 14 of the multi-station Jacquard 10. Different models of multi-station Jacquard 10 only need to adjust the adjusting plate to keep the other 3 pieces (first outer piece 43, second outer piece 45, inner piece 44) consistent in thickness dimensions, unaffected by the needle pitch.
[0111] Other structures are similar to those in Embodiment 3, and will not be described in detail here.
[0112] Example 9, referring to Figure 6 and Figure 7 The difference between Embodiment Nine and Embodiment One is that the multi-station jacquard comb 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 guide needles 12 provided inside the Jacquard comb 120 have a first station, a second station, and a third station.
[0113] 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 it 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, allowing multiple Jacquard combs 120 to be arranged together. When this multi-station jacquard comb is powered on... When processor 112 is not assigned a corresponding communication address, it does not respond. When the master controller 113 does not receive feedback from processor 112, it continuously queries the communication address status of processor 112. When processor 112 detects a communication address setting signal on the first interface 110 and that it has not been assigned a corresponding communication address, it sets the address value currently queried on the communication bus 114 as its first communication address. Processor 112 then responds to the master controller 113's query using this first communication address as its corresponding communication address status. The communication address setting signal can be configured to be a high-level signal.
[0114] 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.
[0115] 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.
[0116] 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.
[0117] 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.
[0118] 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.
[0119] 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.
[0120] 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.
[0121] 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.
[0122] The principle behind automatic address encoding in this embodiment is as follows:
[0123] 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.
[0124] 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.
[0125] 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.
[0126] 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.
[0127] 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.
[0128] 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.
[0129] 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.
[0130] 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.
[0131] 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.
[0132] Other structures are similar to those in Embodiment 1, and will not be described in detail here.
[0133] Example 10, referring to Figure 6 ,and Figure 7 The difference between this embodiment ten and embodiment one is that the multi-station jacquard comb 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 set in the Jacquard comb 120.
[0134] 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 multi-station jacquard comb 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.
[0135] 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.
[0136] 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.

[0140] 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.
[0141] 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.
[0142] 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.
[0143] 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.

[0145] 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.
[0146] 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.
[0147] 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.
[0148] 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.

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.

The number of Jacquard combs can be determined according to the machine number of the warp knitting machine.
[0154] 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).
[0155] 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.
[0156] Other structures are similar to those in Embodiment Nine, and will not be described in detail here.
[0157] 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.
