Description

Technical Field

[0001] This invention relates to the field of warp knitting machines, and in particular to a jacquard knitting device and a warp knitting machine with multiple patterns. Background Technology

[0002] Typically, a complete jacquard application consists of two comb mounting sections, with each comb mounting section having jacquards corresponding to odd and even pin positions. The reason for dividing a complete jacquard application into two groups, using an E24 pin pitch jacquard as an example, is that the pin pitch of each E24 pin is 1.058mm, while the thickness of the piezoelectric ceramic sheet is already 0.8mm. Clearly, it's impossible to place a piezoelectric ceramic sheet on a single base within such a spacing. Therefore, the odd and even pin positions of the E24 ceramic sheet with a 1.058mm pin pitch are extracted and divided into two groups. Thus, the pin pitch of the jacquard column in either the odd or even row doubles to 2.116mm, a distance sufficient to place a ceramic sheet of the current thickness. Therefore, in practice, a complete Jacquard application consists of odd-numbered rows and even-numbered rows on two comb mounting sections. During installation, the odd-numbered rows and even-numbered rows are staggered by one stitch, thus forming a complete Jacquard application.

[0003] A complete single jacquard application (1 odd and 1 even = 2 comb mounting units) is a single jacquard application. Two sets (2 odd and 2 even = 4 comb mounting units) constitute a double jacquard application, and so on. Currently, the jacquard configuration consists of only one row of piezoelectric ceramic sheets on each base. Multiple horizontally distributed bases simply increase the total number of these piezoelectric ceramic sheets, but the total number remains one row (layer). Two sets of horizontally distributed jacquards (odd and even) represent two separate rows.

[0004] In the existing technology, the double Jacquard warp knitting machine has two jacquard units composed of piezoelectric Jacquard combs. In the existing Jacquard jacquard device, a base is required to install the piezoelectric Jacquard elements, and then the Jacquard jacquard device is installed on the comb mounting part. A jacquard unit has two rows of comb mounting parts and two rows of bottom bases, which results in four rows of comb mounting parts and four rows of bottom bases in a double Jacquard warp knitting machine, and six rows of comb mounting parts and six rows of bottom bases in a triple Jacquard warp knitting machine (for details, please refer to Chinese Utility Model Patent (Application No.: 202121809958.7, Publication No.: CN216040097U) which discloses a triple Jacquard double needle bed warp knitting machine, Chinese Utility Model Patent (Application No.: 201520456123.6, Publication No.: CN204849251U) which discloses a double Jacquard warp knitting machine with a pressure plate, and Chinese Utility Model Patent (Application No.: 201520456123.6, Publication No.: CN204849251U) which discloses an eight-comb double Jacquard comb arrangement and swing mechanism).

[0005] However, the comb mounting section and the base only serve to connect and install the combs. In the case of limited installation space inside the comb mounting cradle, they also occupy space and affect the spacing between the two Jacquard combs. These extra comb mounting sections and bases occupy space and increase the weight of the Jacquard combs.

[0006] In recent years, the industry has begun to study the weaving method of the three-station jacquard device. However, there is a lack of a jacquard device on the market that can stably realize the three-station jacquard. The guide needle of the jacquard device can stop at the three stations respectively, thereby realizing the three-station jacquard yarn guidance, so as to realize the weaving method of the above-mentioned three-station jacquard warp knitting jacquard products. Summary of the Invention

[0007] This invention provides a jacquard knitting device and a warp knitting machine with multiple patterns, the main purpose of which is to overcome the deficiency of existing jacquard knitting devices that can only achieve two stations.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A jacquard knitting device and a warp knitting machine with multiple patterns are disclosed. The warp knitting machine is a double jacquard warp knitting machine or a triple jacquard warp knitting machine. The jacquard knitting device includes at least one mounting structure and at least one first jacquard actuator disposed on the upper surface of the mounting structure. The first jacquard actuator has a plurality of first yarn guide needles for jacquard yarn guiding. It also includes at least one second jacquard actuator disposed on the lower surface of the mounting structure, at least one first needle position adjuster disposed on the upper surface of the mounting structure, and at least one second needle position adjuster disposed on the lower surface of the mounting structure. The second jacquard actuator has a plurality of second yarn guide needles for jacquard yarn guiding. The first needle position adjuster has a plurality of first blocking portions adapted to the first yarn guide needles. The second needle position adjuster has a plurality of second blocking portions adapted to the second yarn guide needles. The first blocking portions are used to restrict the first yarn guide needles to stop oscillating at three different first preset positions. The second blocking portions are used to restrict the second yarn guide needles to stop oscillating at three different second preset positions.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] This invention features a simple structure and strong practicality. By mounting the first jacquard actuator, the second jacquard actuator, the first needle position adjuster, and the second needle position adjuster on the upper and lower surfaces of the mounting structure, a jacquard unit is formed by the first yarn guide needle and the second yarn guide needle. On the one hand, during installation, it is only necessary to directly install the tail of the mounting structure onto the guide rod of the warp knitting machine to complete the installation. On the other hand, the first blocking part is used to restrict the first yarn guide needle to stop swinging at three different first preset positions, and the second blocking part is used to restrict the second yarn guide needle to stop swinging at three different second preset positions. This gives both the first and second yarn guide needles the function of three positions, effectively increasing the patterns produced by the jacquard unit and achieving two benefits at once.

The mounting structure 1, the first needle grooves 10, and the second needle grooves 11 can be made of magnesium alloy, aluminum alloy, or magnesium-aluminum alloy.

[0022] Reference Figure 2 , Figure 3 and Figure 4 The first jacquard actuator 2 has multiple first yarn guide needles 6 for jacquard yarn guiding, the second jacquard actuator 3 has multiple second yarn guide needles 7 for jacquard yarn guiding, the first needle position adjuster 4 has multiple first blocking parts 8 adapted to the first yarn guide needles 6, and the second needle position adjuster 5 has multiple second blocking parts 9 adapted to the second yarn guide needles 7. The first blocking parts 8 are used to restrict the first yarn guide needles 6 to stop swinging at three different first preset positions 12, and the second blocking parts 9 are used to restrict the second yarn guide needles 7 to stop swinging at three different second preset positions 13.

[0023] Reference Figure 2 , Figure 3 and Figure 4By installing the first jacquard actuator 2, the second jacquard actuator 3, the first needle position adjuster 4, and the second needle position adjuster 5 on the upper and lower surfaces of the mounting structure 1 respectively, a jacquard unit 10 is formed by the first yarn guide needle 6 and the second yarn guide needle 7. On the one hand, during installation, it is only necessary to directly install the tail of the mounting structure 1 onto the guide rod of the warp knitting machine to complete the installation. On the other hand, the first blocking part 8 is used to restrict the first yarn guide needle 6 to stop swinging at three different first preset positions 12, and the second blocking part 9 is used to restrict the second yarn guide needle 7 to stop swinging at three different second preset positions 13, so that both the first yarn guide needle 6 and the second yarn guide needle 7 have the function of three positions, effectively increasing the patterns produced by the jacquard unit 10, achieving a dual benefit.

[0024] Reference Figure 1 The first guide needle 6 and the second guide needle 7 are respectively arranged on both sides of the mounting structure 1 to form a jacquard unit 10.

[0025] Reference Figure 3 The first preset station 12 includes a first station 14, a second station 15, and a third station 16. The first station 14 is the first needle position of the first yarn guide needle 6, the third station 16 is the last needle position of the first yarn guide needle 6, and the second station 15 is the intermediate station between the first needle position and the first needle position of the first yarn guide needle 6. Figure 3 The image shows the first guide needle 6 stopping at the second work station 15.

[0026] Reference Figure 4 The second preset station 13 includes a fourth station 17, a fifth station 18, and a sixth station 19. The fourth station 17 is the first needle position of the second yarn guide needle 7, the sixth station 19 is the last needle position of the second yarn guide needle 7, and the fifth station 18 is the intermediate station between the first needle position and the last needle position of the second yarn guide needle 7. Figure 4 The image shows the second guide needle 7 stopping at the fifth station 18.

[0027] Reference Figure 3 One side of the first needle groove 10 is used to block the corresponding first guide needle 6, so that the corresponding first guide needle 6 stops swinging at the first station 14. The other side of the first needle groove 10 is used to block one side of the corresponding first blocking part 8, so that when the first blocking part 8 stops swinging on the other side of the corresponding first needle groove 10, the corresponding first guide needle 6 can swing into the third station 16 and stop.

[0028] Reference Figure 3By setting the other side of the first needle groove 10 to block one side of the corresponding first blocking part 8, the third station 16 is effectively positioned by the other side of the first needle groove 10, so that the first blocking part 8 can stop accurately at the third station 16. On the other hand, the first blocking part 8 is effectively restricted, improving the accuracy of the first yarn guide needle 6 entering the third station 16, achieving two benefits at once.

[0029] Reference Figure 4 One side of the second needle groove 11 is used to block the corresponding second guide needle 7, so that the corresponding second guide needle 7 stops swinging at the fourth station 17. The other side of the second needle groove 11 is used to block one side of the corresponding second blocking part 9, so that when the second blocking part 9 stops swinging on the other side of the corresponding second needle groove 11, the corresponding second guide needle 7 can swing into the sixth station 19 and stop.

[0030] Reference Figure 4 By setting the other side of the second needle groove 11 to block one side of the corresponding second blocking part 9, the fifth station 18 is effectively positioned by the other side of the second needle groove 11, so that the second blocking part 9 can stop accurately at the fifth station 18. On the other hand, the second blocking part 9 is effectively restricted, improving the accuracy of the second yarn guide needle 7 entering the fifth station 18, achieving two benefits at once.

[0031] Reference Figure 1 and Figure 2 The first jacquard actuator 2 includes multiple first piezoelectric Jacquard elements 200. Each first piezoelectric Jacquard element 200 includes a first substrate, first piezoelectric ceramic sheets 20 wrapped on the left and right sides of the first substrate, two first electrical terminals 22 disposed on the tail of the first substrate, a first comb holding end 21 disposed on the front of the first substrate, and a first yarn guide needle 6 disposed on the front of the first comb holding end 21. The first electrical terminals 22 are electrically connected to the first piezoelectric ceramic sheets 20. When the first electrical terminals 22 are energized, an electrical signal is applied to the first piezoelectric ceramic sheets 20 to make the first piezoelectric ceramic sheets 20 swing left and right, thereby driving the first yarn guide needle 6 to swing left and right.

[0032] Reference Figure 1 and Figure 2The second jacquard actuator 3 includes multiple second piezoelectric Jacquard elements 300. Each second piezoelectric Jacquard element 300 includes a third substrate, third piezoelectric ceramic sheets 23 wrapped around the left and right sides of the third substrate, two third electrical terminals 25 disposed at the tail of the third substrate, a second comb holding end 24 disposed at the front of the third substrate, and a second yarn guide needle 7 disposed at the front of the second comb holding end 24. The third electrical terminals 25 are electrically connected to the third piezoelectric ceramic sheets 23. When the third electrical terminals 25 are energized, an electrical signal is applied to the third piezoelectric ceramic sheets 23, causing the third piezoelectric ceramic sheets 23 to swing left and right, thereby driving the second yarn guide needle 7 to swing left and right.

[0033] Reference Figure 1 and Figure 2 The first needle position adjuster 4 includes a second substrate, second piezoelectric ceramic sheets 26 wrapped on the left and right sides of the second substrate, two second electrical terminals 27 disposed on the tail of the second substrate, and a first blocking part 8 disposed on the front of the second substrate. The second electrical terminals 27 are electrically connected to the second piezoelectric ceramic sheets 26. When the second electrical terminals 27 are energized, an electrical signal is applied to the second piezoelectric ceramic sheets 26 to make the second piezoelectric ceramic sheets 26 swing left and right, thereby driving the first blocking part 8 to swing left and right.

[0034] Reference Figure 1 and Figure 2 The second pin position adjuster 5 includes a fourth substrate, a fourth piezoelectric ceramic sheet 28 wrapped on the left and right sides of the fourth substrate, two fourth electrical terminals 29 disposed on the tail of the fourth substrate, and a second blocking part 9 disposed on the front of the fourth substrate. The fourth electrical terminals 29 are electrically connected to the fourth piezoelectric ceramic sheet 28. When the fourth electrical terminals 29 are energized, an electrical signal is applied to the fourth piezoelectric ceramic sheet 28 to make the fourth piezoelectric ceramic sheet 28 swing left and right, thereby driving the second blocking part 9 to swing left and right.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first blocking part 8 can be a first baffle 30 used to block the corresponding first guide needle 6. The second blocking part 9 can be a second baffle 31 used to block the corresponding second guide needle 7.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first blocking part 8 is disposed on the side of the first yarn guide needle 6 facing the third station 16. When the torque of the first blocking part 8 is greater than the torque of the first yarn guide needle 6, the first blocking part 8 pushes the first yarn guide needle 6 to move to the second station 15. When the initial moving position of the first yarn guide needle 6 is at the third station 16, the first blocking part 8 pushes the first yarn guide needle 6 from the third station 16 to the second station 15.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The second blocking part 9 is disposed on the side of the second yarn guide needle 7 facing the sixth station 19. When the torque of the second blocking part 9 is greater than the torque of the second yarn guide needle 7, the second blocking part 9 pushes the second yarn guide needle 7 to move to the fifth station 18. When the initial moving position of the second yarn guide needle 7 is at the sixth station 19, the second blocking part 9 pushes the second yarn guide needle 7 from the sixth station 19 to the fifth station 18.

[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the length of the second piezoelectric ceramic sheet 26 is set to be greater than the length of the first piezoelectric ceramic sheet 20, so that the torque of the second piezoelectric ceramic element 500 is greater than the torque of the first piezoelectric Jacquard element 200. Similarly, the length of the fourth piezoelectric ceramic sheet 28 is set to be greater than the length of the third piezoelectric ceramic sheet 23, so that the torque of the fourth piezoelectric ceramic element is greater than the torque of the second piezoelectric Jacquard element 300.

[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 By installing the first jacquard actuator 2 and the first needle position adjuster 4 on the upper surface of the mounting structure 1, the first Jacquard needle has a three-position jacquard function. By installing the second jacquard actuator 3 and the second needle position adjuster 5 on the lower surface of the mounting structure 1, the second Jacquard needle has a three-position jacquard function. Its structure is compact. When the Jacquard jacquard device is installed on the warp knitting machine, it reduces the space occupied by one row of bases 41. It achieves the effect of installing two rows of piezoelectric Jacquard elements by using only one row of bases 41, saving the cost of one row of bases 41 and improving the integration of the Jacquard jacquard device. This makes the Jacquard jacquard device well applicable to the use needs of double Jacquard warp knitting machines or triple Jacquard warp knitting machines.

[0040] Example 2, refer to Figure 5 and Figure 6 The difference between this second embodiment and the first embodiment is that:

[0041] The mounting mechanism includes a base 41, a first receiving groove 42 disposed on the upper surface of the base 41, and a second receiving groove 43 disposed on the upper surface of the base 41. The first jacquard actuator 2 also includes a plurality of first piezoelectric Jacquard elements 200 for driving the corresponding first guide needle 6 to swing. A portion of the first piezoelectric Jacquard elements 200 is installed in the first receiving groove 42. The first needle position adjuster 4 also includes a plurality of first piezoelectric ceramic elements 400 for driving the corresponding first blocking part 8 to swing. A portion of the first piezoelectric ceramic elements 400 is installed in the second receiving groove 43. The first piezoelectric Jacquard elements 200 are stacked on top of the first piezoelectric ceramic elements 400 in a bottom-to-top order.

[0042] Reference Figure 5 and Figure 6 By separately stacking the first piezoelectric Jacquard element 200 and the first piezoelectric ceramic element 400, the first piezoelectric Jacquard element 200 and the first piezoelectric ceramic element 400 can operate independently and without interference during their respective oscillations, thereby effectively maintaining the stability of the first piezoelectric Jacquard element 200 and the first piezoelectric ceramic element 400 during long-term oscillations and improving the stability of the first jacquard actuator 2.

[0043] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0044] Example 3, referring to Figure 1 and Figure 2 The difference between this embodiment three and embodiment two is that the first piezoelectric ceramic element 400 is stacked on top of the first piezoelectric Jacquard element 200 in a bottom-to-top order.

[0045] Other structures are similar to those in Embodiment 2, and will not be described in detail here.

[0046] Example 4, refer to Figure 5 and Figure 6 The difference between this embodiment four and embodiment one is that the mounting mechanism further includes a third receiving groove 44 and a fourth receiving groove 45 disposed on the lower surface of the base 41. The second jacquard actuator 3 further includes a plurality of second piezoelectric Jacquard elements 300 for driving the corresponding second guide needle 7 to swing. A portion of the second piezoelectric Jacquard elements 300 is installed in the third receiving groove 44. The second needle position adjuster 5 further includes a plurality of second piezoelectric ceramic elements 500 for driving the corresponding second blocking part 9 to swing. A portion of the second piezoelectric ceramic elements 500 is installed in the fourth receiving groove 45. The second piezoelectric Jacquard elements 300 are stacked on top of the second piezoelectric ceramic elements 500 in a bottom-to-top order.

[0047] Reference Figure 5 and Figure 6By stacking the second Jacquard element and the second piezoelectric ceramic element 500 separately, the second Jacquard element and the second piezoelectric ceramic element 500 can operate independently and without interference during their respective oscillations, thereby effectively maintaining the stability of the second Jacquard element and the second piezoelectric ceramic element 500 during long-term oscillations and improving the stability of the second jacquard actuator 3.

[0048] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0049] Example 5, refer to Figure 1 and Figure 2 The difference between this fifth embodiment and the fourth embodiment is that the second piezoelectric ceramic element 500 is stacked on top of the second piezoelectric Jacquard element 300 in a bottom-to-top order.

[0050] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, at least a portion of the first blocking part 8 is displaced along the moving direction by the second piezoelectric ceramic sheet 26. The first blocking part 8 extends into the space between the two first needle grooves 10. The first blocking part 8 is used to block a portion of the first yarn guide needle 6 from displacing along the moving direction. When a portion of the first yarn guide needle 6 comes into contact with the first blocking part 8 in a swinging manner, the needle position of the first yarn guide needle 6 is restricted to one side of the first blocking part 8 and stops swinging.

[0051] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 By setting a second piezoelectric ceramic sheet 26 stacked on top of the first piezoelectric ceramic sheet 20, and the first blocking part 8 extending into the space between the two first needle grooves 10, on the one hand, without affecting the swing of the existing first piezoelectric ceramic sheet 20, the installation of the second piezoelectric ceramic sheet 26 drives the first blocking part 8 to swing, thereby not affecting the jacquard yarn guiding of the original two working positions of the first yarn guiding needle 6, and maintaining the stability of the original swing of the first yarn guiding needle 6. On the other hand, the first blocking part 8 blocks the corresponding first yarn guiding needle 6, so that the first yarn guiding needle 6 stops swinging at the preset position of the first blocking part 8, thereby achieving the effect of increasing the number of working positions of the first yarn guiding needle 6, which achieves two benefits at once.

[0052] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4Each pair of adjacent first needle grooves 10 surrounds a first cavity 34 for respectively accommodating the corresponding first yarn guide needle 6 and the corresponding first blocking part 8. The left side of the first cavity 34 is the first station 14, the right side of the first cavity 34 is the third station 16, and the middle position of the first cavity 34 is the second station 15. The distance between the second station 15 and the third station 16 is one needle pitch. The first blocking part 8 switches between the second station 15 and the third station 16 in a swinging manner. When the first blocking part 8 stops swinging at the second station 15, the first blocking part 8 prevents the corresponding first yarn guide needle 6 from stopping swinging at the corresponding second station 15. When the first blocking part 8 stops at the third station 16, the first blocking part 8 prevents the corresponding first yarn guide needle 6 from stopping swinging at the corresponding third station 16.

[0053] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 By setting the first blocking part 8 to switch back and forth between the second station 15 and the third station 16, the first needle position adjuster 4 can switch between the two-station and three-station as needed, thereby increasing the applicability of the first jacquard actuator 2 and increasing the number of jacquard patterns.

[0054] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the width of the first guide needle 6 along the moving direction is greater than the width of the first blocking part 8 along the moving direction. The first blocking part 8 is arranged laterally and offset from the moving direction in the movement space of the first guide needle 6. Each first blocking part 8 is held on a part of the first needle groove 10 at at least two different positions.

[0055] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 By setting the length of the second piezoelectric ceramic sheet 26 to be greater than the length of the first piezoelectric ceramic sheet 20, the torque of the second piezoelectric ceramic sheet 26 is greater than the torque of the first piezoelectric ceramic sheet 20. This allows the first baffle 30 to effectively block the impact of the first yarn guide needle 6 on the first baffle 30, so that the first yarn guide needle 6 can be intercepted by the first baffle 30 at the second station 15 or at the third station 16, thereby improving the stability and accuracy of the three-station switching process.

[0056] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4By setting the installation position of the second piezoelectric ceramic sheet 26 higher than that of the first piezoelectric ceramic sheet 20, the installed second piezoelectric ceramic sheet 26 and the original first piezoelectric ceramic sheet 20 do not affect each other. At the same time, it is also convenient for the production of the base 41 and improves the stability of the first needle position adjuster 4.

[0057] Reference Figure 1 The principle of the first jacquard actuator 2 achieving three stations:

[0058] Reference Figure 3 The swing amplitude of the first jacquard actuator 2 in the dual-station configuration is one slotted needle position, while the swing amplitude of the first jacquard actuator 2 in the three-station configuration is two slotted needle positions (two needle pitches) due to the addition of a station state. That is, without lateral movement, its swing amplitude is two slotted needle positions (two needle pitches).

[0059] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first jacquard actuator 2 of the three-station system refers to the first guide needle 6, which, in addition to swinging left and right, must be able to accurately stop at the middle position.

[0060] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first jacquard actuator 2 in the dual-station configuration can only swing left and right, and its stopping position is fixed and accurate. This fixed and accurate position is achieved because after the comb teeth of the base 41 are slotted according to calculated data, the first guide needle 6 will stop on the tooth wall when swinging left or right. Since the spacing of the tooth walls is calculated, as long as the tooth wall spacing is correct, the needle position is correct. The piezoelectric ceramic sheet generates a swinging torque after charging. A complete piezoelectric ceramic sheet capable of swinging left and right is composed of two individual piezoelectric ceramic sheets bonded to a glass fiber sheet. Each individual piezoelectric ceramic sheet is responsible for one swinging direction; that is, when one sheet is charged and the other is discharged, the correct swinging torque is generated, causing the piezoelectric ceramic sheet to swing left or right. This is the basic swinging principle of the piezoelectric ceramic sheet.

[0061] Reference Figure 2 and Figure 3 As long as a sufficiently large torque is generated, the first guide needle 6 will be pressed tightly against the wall of the first needle groove 10 on one side of the base 41 under the drive of the first piezoelectric ceramic sheet 20, and will not be deflected by the yarn, so it can accurately pass through the center of the two groove needles.

[0062] Reference Figure 2 and Figure 3 The first needle groove 10 in the base 41 is structurally a first groove 33 with a first step 32.

[0063] Reference Figure 2 and Figure 3 The width of the first cavity 34 is the width of two stitches, the width of the first groove 33 is the width of one stitch, and there is a first step 32 between the first cavity 34 and the first groove 33.

[0064] Reference Figure 2 and Figure 3 The first piezoelectric ceramic sheet 20 drives the first yarn guide needle 6 to swing in the first cavity 34. The position of the first yarn guide needle 6 is higher than the first step 32, so it is not affected by the first step 32. Since the width of the first cavity 34 is the width of two needle pitches, the first piezoelectric ceramic sheet 20 drives the first yarn guide needle 6 to swing to a position of two needle pitches in the first cavity 34.

[0065] Reference Figure 2 and Figure 3 After the second piezoelectric ceramic sheet 26 is set, when the first baffle 30 at the front end of the second piezoelectric ceramic sheet 26 is running, since the lower part of the first baffle 30 is in the first groove 33, the first baffle 30 will be blocked by the first step 32 and the toothed wall (the wall on the other side of the first needle groove 10) when it swings. Therefore, the first baffle 30 is restricted to swinging left and right only in the first groove 33. Since the first groove 33 is set to a width of one needle pitch, the first baffle 30 can swing left and right for one needle pitch within the first groove 33. Since the first step 32 limits the first baffle 30, the first baffle 30 can only swing between the first step 32 and the rightmost toothed wall.

[0066] Reference Figure 2 and Figure 3 The second piezoelectric ceramic sheet 26 is made longer to increase its torque. Due to the need to achieve three stations, the torque of the second piezoelectric ceramic sheet 26 must be set to be greater than that of the first piezoelectric ceramic sheet 20, so that the pushing force of the first baffle 30 on the first guide needle 6 is greater than the pressure of the first guide needle 6 on the first baffle 30, thereby causing the first baffle 30 to push the first guide needle 6 from the third station 16 to the second station 15.

[0067] Reference Figure 2 and Figure 3 The following explains how the first jacquard actuator 2 of the three-station system works by switching between the three stations, described separately for left, center, and right:

[0068] Reference Figure 2 and Figure 3 When the first guide needle 6 is on the left (first station 14): the drive circuit controls the first piezoelectric ceramic plate 20 to swing to the left, and the needle position is at the leftmost position (first station 14). At this time, the position of the first baffle 30 can be anywhere and has no effect on the current leftmost needle position (first station 14).

[0069] Reference Figure 2 and Figure 3 When the first guide needle 6 is in the middle (second station 15): the drive circuit controls the second piezoelectric ceramic plate 26 to make the first stop plate 30 swing to the left, and at the same time, controls the first guide needle 6 to swing to the right. At this time, the first stop plate 30 will be blocked by the first step 32. Since the torque of the first stop plate 30 is greater than that of the first guide needle 6, the first guide needle 6 will press tightly on the first stop plate 30, but will not push the first stop plate 30 away and cause needle deviation. So the final result is that the first stop plate 30 stops after being blocked by the first step 32, and the first guide needle 6 presses on the first stop plate 30. Since the position of the first stop plate 30 when it stops against the first step 32 is exactly one needle pitch (i.e., the position of the second station 15), it is equivalent to the first guide needle 6 being in the middle station (i.e., the position of the second station 15).

[0070] Reference Figure 2 and Figure 3 When the first guide needle 6 is on the right (third station 16): the drive circuit controls the first piezoelectric ceramic plate 20 to swing to the left, causing the first guide needle 6 to swing to the right, and at the same time controls the second piezoelectric ceramic plate 26 and the first baffle 30 to swing to the right. The first guide needle 6 is in the right position and presses on the first baffle 30. Since the width is preset during the initial milling process of the first needle groove 10, including the thickness of the first baffle 30, the position of the first guide needle 6 pressing on the first baffle 30 is exactly one needle pitch. Therefore, the first guide needle 6 will be in the rightmost position (third station 16) at this time.

[0071] Reference Figure 2 , Figure 3 and Figure 4 At least a portion of the second blocking part 9 is displaced along the moving direction by being driven by the fourth piezoelectric ceramic sheet 28. The second blocking part 9 extends into the space between the two second needle grooves 11. The second blocking part 9 is used to block a portion of the second guide needle 7 from displacing along the moving direction. When a portion of the second guide needle 7 comes into contact with the second blocking part 9 in a swinging manner, the needle position of the second guide needle 7 is restricted to one side of the second blocking part 9 and stops swinging.

[0072] Reference Figure 2 , Figure 3 and Figure 4By setting a fourth piezoelectric ceramic sheet 28 stacked above the third piezoelectric ceramic sheet 23, and the second blocking part 9 extending into the space between the two second needle grooves 11, on the one hand, without affecting the swing of the existing third piezoelectric ceramic sheet 23, the installation of the fourth piezoelectric ceramic sheet 28 drives the second blocking part 9 to swing, thereby not affecting the jacquard yarn guiding of the original two working positions of the second yarn guiding needle 7, and maintaining the stability of the original swing of the second yarn guiding needle 7. On the other hand, the second blocking part 9 blocks the corresponding second yarn guiding needle 7, so that the second yarn guiding needle 7 stops swinging at the preset position of the second blocking part 9, thereby achieving the effect of increasing the number of working positions of the second yarn guiding needle 7, which achieves two benefits at once.

[0073] Reference Figure 2 , Figure 3 and Figure 4 Each pair of adjacent second needle grooves 11 surrounds a second cavity 341 for respectively accommodating the corresponding second guide needle 7 and the corresponding second blocking part 9. The left side of the second cavity 341 is the fourth station 17, the right side of the second cavity 341 is the sixth station 19, and the middle position of the second cavity 341 is the fifth station 18. The distance between the fifth station 18 and the sixth station 19 is one needle pitch. The second blocking part 9 switches between the fifth station 18 and the sixth station 19 in a swinging manner. When the second blocking part 9 stops swinging at the fifth station 18, the second blocking part 9 prevents the corresponding second guide needle 7 from stopping swinging at the corresponding fifth station 18. When the second blocking part 9 stops at the sixth station 19, the second blocking part 9 prevents the corresponding second guide needle 7 from stopping swinging at the corresponding sixth station 19.

[0074] Reference Figure 3 and Figure 4 By setting the second blocking part 9 to switch back and forth between the fifth station 18 and the sixth station 19, the second needle position adjuster 5 can switch between two stations and three stations as needed, thereby increasing the applicability of the second jacquard actuator 3 and increasing the number of jacquard patterns.

[0075] Reference Figure 3 and Figure 4 In this embodiment, the width of the second guide needle 7 along the moving direction is greater than the width of the second blocking part 9 along the moving direction. The second blocking part 9 is arranged laterally and offset from the moving direction within the movement space of the second guide needle 7. Each second blocking part 9 is held on a part of the second needle groove 11 at at least two different positions.

[0076] Reference Figure 2 , Figure 3 and Figure 4By setting the length of the fourth piezoelectric ceramic plate 28 to be greater than the length of the third piezoelectric ceramic plate 23, the torque of the fourth piezoelectric ceramic plate 28 is greater than the torque of the third piezoelectric ceramic plate 23. This allows the second baffle plate 31 to effectively block the impact of the second guide needle 7 on the second baffle plate 31, so that the second guide needle 7 can be intercepted by the second baffle plate 31 at the fifth station 18 or at the sixth station 19, thereby improving the stability and accuracy of the three-station switching process.

[0077] Reference Figure 2 , Figure 3 and Figure 4 By setting the installation position of the fourth piezoelectric ceramic sheet 28 higher than that of the third piezoelectric ceramic sheet 23, the fourth piezoelectric ceramic sheet 28 after installation does not affect the original third piezoelectric ceramic sheet 23. This also facilitates the production of the base 41 and improves the stability of the second pin position adjuster 5.

[0078] Reference Figure 2 and Figure 4 The principle of the second jacquard actuator 3 achieving three stations:

[0079] Reference Figure 2 and Figure 4 The swing amplitude of the second jacquard actuator 3 in the dual-station configuration is one slotted needle position, while the swing amplitude of the second jacquard actuator 3 in the three-station configuration is two slotted needle positions (two needle pitches) due to the addition of a station state. That is, in the absence of lateral movement, its swing amplitude is two slotted needle positions (two needle pitches).

[0080] Reference Figure 2 and Figure 4 The second jacquard actuator 3 in the three-station system refers to the second guide needle 7, which, in addition to swinging left and right, must be able to accurately stop in the middle position.

[0081] Reference Figure 2 and Figure 4 The second jacquard actuator 3 of the dual-station unit can only swing left and right. Its stopping position is fixed and accurate. The reason why it is fixed and accurate is that after the comb teeth of the base 41 are slotted according to the calculated data, the second guide needle 7 will stop on the tooth wall when it swings left or right. Since the spacing of the tooth wall is calculated, as long as the spacing of the tooth wall is correct, the needle position is correct.

[0082] Reference Figure 2 and Figure 4 As long as a sufficiently large torque is generated, the second guide needle 7 will be pressed tightly against the wall of the second needle groove 11 on one side of the base 41 under the drive of the third piezoelectric ceramic plate 23, and will not be deflected by the yarn, so it can accurately pass through the center of the two groove needles.

[0083] Reference Figure 2 and Figure 4 The second needle groove 11 on the base 41 is structurally a second groove 36 with a second step 35.

[0084] Reference Figure 2 and Figure 4 The width of the second cavity 341 is the width of two stitch pitches, the width of the second groove 36 is the width of one stitch pitch, and there is a second step 35 between the second cavity 341 and the second groove 36.

[0085] Reference Figure 2 and Figure 4 The third piezoelectric ceramic sheet 23 drives the second guide needle 7 to swing in the second cavity 341. The position of the second guide needle 7 is higher than the second step 35, so it is not affected by the second step 35. Since the width of the second cavity 341 is the width of two needle pitches, the third piezoelectric ceramic sheet 23 drives the second guide needle 7 to swing to a position of two needle pitches in the second cavity 341.

[0086] Reference Figure 2 and Figure 4 After the fourth piezoelectric ceramic plate 28 is set, when the second baffle 31 at the front end of the fourth piezoelectric ceramic plate 28 is running, since the lower part of the second baffle 31 is in the second groove 36, the second baffle 31 will be blocked by the second step 35 and the tooth wall (the wall on the other side of the second needle groove 11) when it swings. Therefore, the second baffle 31 is restricted to swinging left and right only in the second groove 36. Since the second groove 36 is set to a width of one needle pitch, the second baffle 31 can swing left and right for one needle pitch within the second groove 36. Since the second step 35 limits the second baffle 31, the second baffle 31 can only swing between the second step 35 and the rightmost tooth wall.

[0087] Reference Figure 2 and Figure 4 The fourth piezoelectric ceramic plate 28 is made longer to increase its torque. Due to the need to achieve three stations, the torque of the fourth piezoelectric ceramic plate 28 must be set to be greater than that of the third piezoelectric ceramic plate 23, so that the pushing force of the second baffle plate 31 on the second guide needle 7 is greater than the pressure of the second guide needle 7 on the second baffle plate 31, thereby causing the second baffle plate 31 to push the second guide needle 7 from the sixth station 19 to the fifth station 18.

[0088] Reference Figure 2 and Figure 4 The following explains how the second jacquard actuator 3 in the three-station configuration works and switches between the three stations, described separately for left, center, and right:

[0089] Reference Figure 2 and Figure 4When the second guide needle 7 is on the left (fourth station 17): the drive circuit controls the third piezoelectric ceramic plate 23 to swing to the left, and the needle position is at the leftmost position (fourth station 17). At this time, the position of the second baffle 31 can be anywhere and has no effect on the current leftmost needle position (fourth station 17).

[0090] Reference Figure 2 and Figure 4 When the second guide needle 7 is in the middle (fifth station 18): the drive circuit controls the fourth piezoelectric ceramic plate 28 to make the second stop plate 31 swing to the left, and at the same time, controls the second guide needle 7 to swing to the right. At this time, the second stop plate 31 will be blocked by the second step 35. Since the torque of the second stop plate 31 is greater than that of the second guide needle 7, the second guide needle 7 will press tightly on the second stop plate 31, but will not push the second stop plate 31 away and cause needle deviation. So the final result is that the second stop plate 31 stops after being blocked by the second step 35, and the second guide needle 7 presses on the second stop plate 31. Since the position of the second stop plate 31 when it stops on one side of the second step 35 is exactly one needle pitch (i.e., the position of the fifth station 18), it is equivalent to the second guide needle 7 being in the middle station (i.e., the position of the fifth station 18).

[0091] Reference Figure 2 and Figure 4 When the second guide needle 7 is on the right (sixth station 19): the drive circuit controls the third piezoelectric ceramic plate 23 to swing to the left, causing the second guide needle 7 to swing to the right. At the same time, it controls the fourth piezoelectric ceramic plate 28 and the second baffle 31 to swing to the right. The second guide needle 7 is in the right position and presses on the second baffle 31. Since the width is preset during the initial milling process of the second needle groove 11, the position of the second guide needle 7 pressing on the second baffle 31 is exactly one needle pitch, including the thickness of the second baffle 31. Therefore, the second guide needle 7 will be in the rightmost position (sixth station 19).

[0092] Other structures are similar to those in Embodiment 4, and will not be described in detail here.

[0093] Example 6, refer to Figure 7 The difference between this sixth embodiment and the first embodiment is that it further includes at least one N+1 jacquard actuator 50 disposed on the upper surface of the mounting structure 1, at least one N+2 jacquard actuator 51 disposed on the lower surface of the mounting structure 1, at least one N+1 needle position adjuster 52 disposed on the upper surface of the mounting structure 1, at least one N+2 needle position adjuster 53 disposed on the lower surface of the mounting structure 1, a plurality of N+1 needle grooves 541 arranged on the upper front surface of the mounting structure 1, and a plurality of N+2 needle grooves 551 arranged on the lower front surface of the mounting structure 1, wherein N≥2.

[0094] Reference Figure 7The N+1th jacquard actuator 50 and at least one N+1th needle position adjuster 52 are stacked on top of the first jacquard actuator 2 from bottom to top.

[0095] Reference Figure 7 The N+2 jacquard actuator 51 and at least one N+2 needle position adjuster 53 are stacked on top of the second jacquard actuator 3 from bottom to top.

[0096] Reference Figure 7 The N+1 jacquard actuator 50 has multiple N+1 yarn guide needles 56 for jacquard yarn guiding, the N+2 jacquard device has multiple N+2 yarn guide needles 57 for jacquard yarn guiding, the N+1 needle position adjuster 52 has multiple N+1 blocking portions 58 adapted to the N+1 yarn guide needles 56, and the N+2 needle position adjuster 53 has multiple N+2 blocking portions 70 adapted to the N+2 yarn guide needles 57. The N+1 blocking portions 58 are used to restrict the N+1 yarn guide needles 56 to stop oscillating at three different N+1 preset positions, and the N+2 blocking portions 70 are used to restrict the N+2 yarn guide needles 57 to stop oscillating at three different N+2 preset positions.

[0097] Reference Figure 7 By mounting the N+1 jacquard actuator 50, the N+2 jacquard actuator 51, the N+1 needle position adjuster 52, and the N+2 needle position adjuster 53 on the upper and lower surfaces of the mounting structure 1, a jacquard unit 10 is formed by the N+1 guide needle 56 and the N+2 guide needle 57. On the one hand, during installation, it is only necessary to directly install the tail of the mounting structure 1 onto the guide rod of the warp knitting machine to complete the installation. On the other hand, the N+1 blocking part 58 is used to restrict the N+1 guide needle 56 to stop swinging at three different N+1 preset positions, and the N+2 blocking part 70 is used to restrict the N+2 guide needle 57 to stop swinging at three different N+2 preset positions. This makes both the N+1 guide needle 56 and the N+2 guide needle 57 have the function of three positions, effectively increasing the patterns produced by the jacquard unit 10, achieving a dual effect.

[0098] Reference Figure 7 The N+1 guide needle 56 and the N+2 guide needle 57 are respectively arranged on both sides of the mounting structure 1 to form a jacquard unit 10.

[0099] Reference Figure 7 The N+1 preset station includes an N+5 station, an N+6 station, and an N+7 station. The N+5 station is the first needle position of the N+1 guide needle 56, the N+7 station is the last needle position of the N+1 guide needle 56, and the N+6 station is the intermediate station between the first needle position of the N+1 guide needle 56 and the first needle position of the N+1 guide needle 56.

[0100] Reference Figure 7 The N+2 preset station includes an N+8 station, an N+9 station, and an N+10 station. The N+8 station is the first needle position of the N+2 guide needle 57, the N+10 station is the last needle position of the N+2 guide needle 57, and the N+9 station is the intermediate station between the first needle position and the last needle position of the N+2 guide needle 57.

[0101] Reference Figure 7 One side of the N+1th needle groove 541 is used to block the corresponding N+1th yarn guide needle 56, so that the corresponding N+1th yarn guide needle 56 stops swinging at the N+5th station. The other side of the N+1th needle groove 541 is used to block one side of the corresponding N+1th blocking part 58, so that when the N+1th blocking part 58 stops swinging on the other side of the corresponding N+1th needle groove 541, the corresponding N+1th yarn guide needle 56 can swing into the N+7th station and stop.

[0102] Reference Figure 7 By setting the other side of the N+1 needle groove 541 to block one side of the corresponding N+1 blocking part 58, the N+7 station is effectively positioned by the other side of the N+1 needle groove 541, so that the N+1 blocking part 58 can stop accurately at the N+7 station. On the other hand, the N+1 blocking part 58 is effectively restricted, improving the accuracy of the N+1 guide needle 56 entering the N+7 station, achieving a dual effect.

[0103] Reference Figure 7 One side of the N+2 needle groove 551 is used to block the corresponding N+2 guide needle 57, so that the corresponding N+2 guide needle 57 stops swinging at the N+8 station. The other side of the N+2 needle groove 551 is used to block one side of the corresponding N+2 blocking part 70, so that when the N+2 blocking part 70 stops swinging on the other side of the corresponding N+2 needle groove 551, the corresponding N+2 guide needle 57 can swing into the N+9 station and stop.

[0104] Reference Figure 7 By setting the other side of the N+2 needle groove 551 to block one side of the corresponding N+2 blocking part 70, the N+9 station is effectively positioned by the other side of the N+2 needle groove 551, so that the N+2 blocking part 70 can stop accurately at the N+9 station. On the other hand, the N+2 blocking part 70 is effectively restricted, which improves the accuracy of the layering when the N+2 guide needle 57 enters the N+9 station, achieving a dual effect.

[0105] Reference Figure 7The N+1th piezoelectric Jacquard element 600 includes an N+1th substrate, N+1th piezoelectric ceramic sheets 62 wrapped on the left and right sides of the N+1th substrate, two N+1th electrical terminals 60 disposed on the tail of the N+1th substrate, an N+1th comb holding end 61 disposed on the front of the N+1th substrate, and an N+1th yarn guide needle 56 disposed on the front of the N+1th comb holding end 61. The N+1th electrical terminals 60 are electrically connected to the N+1th piezoelectric ceramic sheets 62. When the N+1th electrical terminals 60 are energized, an electrical signal is applied to the N+1th piezoelectric ceramic sheets 62 to make the N+1th piezoelectric ceramic sheets 62 swing left and right, thereby driving the N+1th yarn guide needle 56 to swing left and right.

[0106] Reference Figure 7 The N+2 piezoelectric ceramic element 800 includes an N+2 substrate, N+2 piezoelectric ceramic sheets 63 wrapped on the left and right sides of the N+2 substrate, two N+2 electrical terminals 64 disposed on the tail of the N+2 substrate, and an N+2 baffle 66 disposed on the front of the N+2 substrate. The N+2 electrical terminals 64 are electrically connected to the N+2 piezoelectric ceramic sheets 63. When the N+2 electrical terminals 64 are energized, an electrical signal is applied to the N+2 piezoelectric ceramic sheets 63 to make the N+2 piezoelectric ceramic sheets 63 swing left and right, thereby driving the N+2 baffle 66 to swing left and right.

[0107] Reference Figure 7 The (N+1)th blocking part 58 can be the (N+1)th baffle 65 used to block the corresponding (N+1)th yarn guide needle 56. The (N+2)th blocking part 70 can be the (N+2)th baffle 66 used to block the corresponding (N+2)th yarn guide needle 57.

[0108] Reference Figure 7 The (N+1)th blocking part 58 is disposed on the side of the (N+1)th yarn guide needle 56 facing the (N+7)th station. When the torque of the (N+1)th blocking part 58 is greater than the torque of the (N+1)th yarn guide needle 56, the (N+1)th blocking part 58 pushes the (N+1)th yarn guide needle 56 to move to the (N+6)th station. When the initial moving position of the (N+1)th yarn guide needle 56 is at the (N+7)th station, the (N+1)th blocking part 58 pushes the yarn guide needle from the (N+7)th station to the (N+6)th station.

[0109] Reference Figure 7 The (N+2)th blocking part 70 is disposed on the side of the (N+2)th yarn guide needle 57 facing the (N+9)th station. When the torque of the (N+2)th blocking part 70 is greater than the torque of the (N+2)th yarn guide needle 57, the (N+2)th blocking part 70 pushes the (N+2)th yarn guide needle 57 to move to the (N+9)th station. When the initial moving position of the (N+2)th yarn guide needle 57 is at the (N+9)th station, the (N+2)th blocking part 70 pushes the yarn guide needle from the (N+7)th station to the (N+9)th station.

[0110] Reference Figure 7By setting the length of the (N+2)th piezoelectric ceramic plate 63 to be greater than the length of the (N+1)th piezoelectric ceramic plate 62, the torque of the (N+2)th piezoelectric ceramic plate 63 is greater than the torque of the (N+1)th piezoelectric ceramic plate 62. This allows the (N+2)th baffle plate 66 to effectively block the impact of the (N+2)th yarn guide needle 57 on the (N+2)th baffle plate 66. As a result, the (N+2)th yarn guide needle 57 can be intercepted by the (N+2)th baffle plate 66 at the fifth station 18 or at the (N+10)th station, thus improving the stability and accuracy of the (N+10)th station switching process.

By installing the N+2th jacquard actuator 51 and the N+2th needle position adjuster 53 on the lower surface of the mounting structure 1, the N+2th Jacquard needle has the function of three-position jacquard. Its structure is compact. When the Jacquard jacquard device is installed on the warp knitting machine, it reduces the space occupied by one row of bases 41. It achieves the effect of installing two rows of piezoelectric Jacquard elements by using only one row of bases 41, saving the cost of one row of bases 41 and improving the integration of the Jacquard jacquard device. This makes the Jacquard jacquard device well applicable to the use needs of double Jacquard warp knitting machines or triple Jacquard warp knitting machines.

The first power connection port 87 can be respectively disposed on the left and right sides of the first driving circuit board 85. The corresponding piezoelectric ceramic sheet can be a first piezoelectric ceramic sheet 20, a second piezoelectric ceramic sheet 26, a third piezoelectric ceramic sheet 23, a fourth piezoelectric ceramic sheet 28, an (N+1)th piezoelectric ceramic sheet 62, or an (N+2)th piezoelectric ceramic sheet 63.

[0129] The circuit structure of the driving circuit can refer to the driving circuit structure disclosed in Chinese Utility Model Patent (Application No.: 202123378011.8, Publication No.: CN218124570U) or Chinese Utility Model Patent (Application No.: 202121926084.3, Publication No.: CN217486404U), or other driving circuit structures in the field for driving piezoelectric ceramic sheets to oscillate can also be applied.

[0130] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0131] Example 13, referring to Figure 2 , Figure 5 and Figure 7 The difference between Embodiment Thirteen and Embodiment One is that by setting a first needle position adjuster and a second needle position adjuster, the first yarn guide needle in the Jacquard device can perform jacquard yarn guiding at the first, second, and third positions respectively. The second yarn guide needle can perform jacquard yarn guiding at the fourth, fifth, and sixth positions respectively, and a jacquard unit is composed of the first and second jacquard actuators. Therefore, it can be applied to the requirements of warp-knitted jacquard products using a three-position Jacquard system.

[0132] The knitting method of the warp-knitted jacquard product includes: the warp-knitted jacquard product is knitted by the guide needles of the three-station jacquard device, the jacquard comb is configured with one-third machine size and is composed of JB1.1, JB1.2 and JB1.3, and the reverse jacquard is adopted.

[0133] When the control signal for extra-thick tissue is 0012, the odd-numbered rows remain unchanged and form a loop in the first column. The even-numbered rows shift one stitch in front of the needle and two stitches behind the needle, forming a double-warp tissue in the third and fourth columns. When the control signal for extra-thick tissue is 1022, the odd-numbered rows remain unchanged, and the even-numbered rows shift two stitches in front of the needle and two stitches behind the needle, forming a loop in the fourth column.

[0134] When the control signal for thick tissue is 0001, the odd-numbered rows remain unchanged and form a loop in the first column, while the even-numbered rows shift one stitch at the back of the needle, forming a double warp in the second and third columns. When the control signal for thick tissue is 1112, the odd-numbered rows shift one stitch at both the front and back of the needle, forming a loop in the second column, while the even-numbered rows shift one stitch at the front of the needle and two stitches at the back of the needle, forming a double warp in the third and fourth columns.

[0135] When the control signal for thin tissue is 2212, odd-numbered rows shift two stitches before and after the needle, forming a loop in the third column; even-numbered rows shift two stitches before and after the needle, forming a loop in the fourth column. When the control signal for thin tissue is 2201, odd-numbered rows shift two stitches before and after the needle, forming a loop in the third column; even-numbered rows shift one stitch after the needle, forming overlapping tissue in the second and third columns.

[0136] In thin weave structures, when the offset signal of each Jacquard unit of an odd number of yarns is 0000 or 2200, and the yarn padding number is 1-0 / 1-2 / 3-2 / 1-2 / / , and the offset signal of each Jacquard unit of an even number of yarns is 2200 or 0000, and the yarn padding number is 3-2 / 1-2 / 1-0 / 1-2 / / , a small elliptical mesh effect can be obtained. The width of the mesh is approximately one stitch pitch, and the height is approximately two rows.

[0137] When the control signal for the floating thread structure is 0112, the odd-numbered rows are shifted one stitch on the back of the needle, and the even-numbered rows are shifted one stitch on the back of the needle, forming a double warp structure in the second and third warp rows. When the control signal for the floating thread structure is 0110, the odd-numbered rows are shifted one stitch on the back of the needle, and the even-numbered rows are shifted one stitch in front of the needle.

[0138] When the control signal for the mesh structure is 2211, the odd-numbered rows shift by one stitch in front of and behind the needle, forming a circle in the second column, while the even-numbered rows remain unchanged.

[0139] Compared to the two offset signals "0" and "1" of the two-station Jacquard, the three-station Jacquard technology adds an offset signal "2". At this time, the coil offset position is larger, which can form a larger mesh structure.

[0140] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0141] 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.
