Description

TECHNICAL FIELD

[0001] The present application belongs to the field of textile equipment, and particularly relates to a jacquard piece assembly and a jacquard device comprising the same. BACKGROUND

[0002] In the technical field of knitting machines such as fur machines, in order to meet the knitting requirements of diversified fabrics, two different types of needles are usually configured. The two types of needles work together to complete complex knitting actions, thereby realizing the production of fabrics with different textures and styles.

[0003] Corresponding to the above two types of needles are jacquard pieces, which are provided with needle selection teeth that are adapted to electronic needle selectors. In actual knitting process, the electronic needle selector controls the action of the jacquard piece by exerting force on the needle selection teeth on the jacquard piece, thereby realizing the accurate selection of the corresponding needle to determine whether the needle participates in knitting, and finally forming the required fabric pattern and structure.

[0004] However, during the needle selection process of the electronic needle selector, due to the manufacturing precision deviation of the jacquard piece, the electronic needle selector and other components, and the inaccurate alignment between the components during assembly, the electronic needle selector may easily miss the needle or hit the needle during needle selection. Missing the needle will cause the pattern of the knitted fabric to be disordered and the texture to be inconsistent, which will seriously affect the quality of the fabric. Hitting the needle may cause damage to the needle, the jacquard piece and even the electronic needle selector, which not only increases the maintenance cost of the equipment, but also reduces the production efficiency and affects the continuity of production.

[0005] In addition, during the assembly process of the knitting machine, the zero position adjustment of the needle is a crucial task, and the adjustment accuracy directly affects the accuracy of subsequent knitting. However, the existing needles often need to be powered on during zero position adjustment, and the position of the needle is gradually calibrated through the operation of the electronic needle selector. This adjustment method has obvious disadvantages: on the one hand, the adjustment requires specific conditions, and in some power failure or electronic needle selector damage scenarios, the adjustment work is difficult to carry out, and there are condition limitations; on the other hand, the adjustment process is complex, and the presence of the electronic needle selector during the adjustment process may easily lead to needle breakage, resulting in low adjustment efficiency and prolonging the assembly cycle of the equipment.

[0006] In summary, the current problems of the knitting machine in terms of needle selection accuracy and needle zero position adjustment have become important factors restricting the improvement of knitting quality and production efficiency. Therefore, it is of great significance to develop a jacquard piece assembly that can ensure accurate and reliable needle selection and convenient and efficient needle adjustment, in order to promote the development of knitting technology and meet the high-quality production requirements of diversified fabrics. SUMMARY

[0007] The application aims to provide a jacquard piece assembly capable of ensuring accurate and reliable needle selection and convenient and efficient needle adjustment, and a jacquard device comprising the jacquard piece assembly.

[0008] Embodiments of the application can be implemented by the following technical solutions: A jacquard piece assembly comprises a needle and a jacquard piece, the needle comprises a first needle and a second needle, and the first needle and the second needle are installed in the needle groove of the needle cylinder in an alternating arrangement; The side of the jacquard piece facing away from the needle cylinder is provided with a needle selection tooth and a needle separation tooth, the needle separation tooth is located below the needle selection tooth, the needle separation tooth comprises a first needle separation tooth and a second needle separation tooth, and the first needle separation tooth and the second needle separation tooth are respectively arranged on the jacquard piece corresponding to the first needle and the second needle.

[0009] Further, the side of the needle facing away from the needle cylinder is provided with a first needle stitch, and the side of the jacquard piece facing away from the needle cylinder is provided with a second needle stitch, the first needle stitch and the second needle stitch respectively abut against the needle channel of the lower cam track.

[0010] Further, the side of the jacquard piece facing away from the needle cylinder is further provided with a third needle stitch, the third needle stitch is located below the needle separation tooth, and the bottom end of the third needle stitch abuts against the top end of the lifting cam.

[0011] A jacquard device comprises the jacquard piece assembly, a needle cylinder, an electronic needle selector for driving the jacquard piece assembly to complete a jacquard action, and a cam unit for allowing the jacquard piece assembly to work.

[0012] Further, the cam unit comprises a lower cam, a pull-out cam and a lifting cam, the lower cam abuts against the first needle stitch of the needle and the second needle stitch of the jacquard piece, and the space for the bottom end of the jacquard piece to move circumferentially is formed between the pull-out cam and the lifting cam.

[0013] Further, the jacquard device further comprises at least one set of push blocks, each set of push blocks comprises a first push block and a second push block, the height of the first push block corresponds to the position of the first needle separation tooth, the height of the second push block corresponds to the position of the second needle separation tooth, and the first push block and the second push block can respectively abut against the first needle separation tooth and the second needle separation tooth.

[0014] Further, the first push block and the second push block are connected to the side of the lifting cam facing away from the jacquard piece and are respectively connected to the upstream end of the lifting face of the lifting cam along the rotation direction of the needle cylinder.

[0015] Furthermore, the first push block and the second push block each include a connecting part and a working part. The connecting part is connected to the starting triangle, and the working part is connected to the top of the connecting part and extends toward the jacquard piece. One end of the working part facing the jacquard piece is provided with a working end face. The working end face is successively a transition end face and an ejection end face along the rotation direction of the syringe. The transition end face is an inclined surface and is inclined towards the direction of the syringe. The ejection end face is a plane and is flush with the inner side of the needle-starting triangle.

[0016] Furthermore, when there are multiple sets of push blocks, multiple first push blocks and second push blocks are alternately arranged.

[0017] Furthermore, the distance between the first push block and the second push block is determined based on the number of paths of the knitting machine and the specific indexing position.

[0018] The jacquard motif assembly and jacquard apparatus including the jacquard motif assembly provided in the embodiments of this application have at least the following beneficial effects: This application, through the differentiated setting of the first and second needle teeth, enables "pre-classification" of jacquard pieces before electronic needle selection. Jacquard pieces belonging to the first needle are identified by the first needle tooth, while those belonging to the second needle are distinguished by the second needle tooth, effectively adding a "type filtering" mechanism before the needle selection process. When the electronic needle selector is operating, it no longer needs to rely solely on the precise identification of the needle tooth height. Instead, it can first determine the needle category to which the target jacquard piece belongs by judging the type of the needle teeth, and then identify the needle tooth height within that category, significantly reducing the risk of misaligned or collision needles caused by errors in a single height identification. Simultaneously, during needle zero-position adjustment, the physical differentiation of the needle teeth allows for direct grouping and calibration of jacquard pieces corresponding to different types of needles, reducing reliance on the power control of the electronic needle selector. Even in scenarios without a stable power supply, the mechanical structure features can quickly locate the adjustment target, simplifying the operation process, improving adjustment efficiency, and fundamentally addressing the problems of unstable knitting quality and limited production efficiency in existing jacquard devices. In this application, the push block serves as a needle selection auxiliary structure. When the jacquard piece rotates with the needle cylinder to the position of the push block, the first push block contacts the corresponding first dividing needle tooth and applies force, disengaging the jacquard piece corresponding to the first needle from the running track of the starting cam. Similarly, the second push block also acts on the second dividing needle tooth, causing the jacquard piece corresponding to the second needle to disengage from the running track of the starting cam. In this way, the electronic needle selector only needs to select the jacquard piece corresponding to one type of needle on the current starting cam running track during subsequent operations, eliminating the need to distinguish between two needle types. This not only significantly reduces interference factors in the needle selection process but also further improves the accuracy and efficiency of needle selection, enhancing the reliability of the "pre-classification" function.

[0021] The present application will now be further described based on preferred embodiments and with reference to the accompanying drawings.

[0022] The vocabulary used in this specification is for illustrative purposes and is not intended to limit the scope of this application. Unless otherwise expressly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of these terms in this application.

[0023] Furthermore, in the description of the embodiments of this application, various components on the drawings have been enlarged or reduced for ease of understanding, but this is not intended to limit the scope of protection of this application.

[0024] The following will explain the structure of existing jacquard tile assemblies and how they fit together.

[0025] like Figure 1 As shown, the jacquard piece assembly includes knitting needles 11 and jacquard pieces 12. The knitting needles 11 include a first knitting needle 111 and a second knitting needle 112. The first knitting needle 111 and the second knitting needle 112 are installed in the needle groove of the needle cylinder 2 in an alternating arrangement.

[0026] In some specific embodiments of this application, the top of the jacquard piece 12 can be provided with a receiving groove to achieve stable support and effective force transmission for the knitting needle 11.

[0027] In some preferred embodiments of this application, such as Figure 1 As shown, the knitting needle 11 and the jacquard piece 12 are connected end-to-end in a sequential abutting manner. On the one hand, this end-to-end abutting ensures direct and efficient force transmission between the two, allowing the movement of the jacquard piece 12 to be precisely synchronized with the knitting needle 11, reducing power loss and action delay. On the other hand, this structure is simple and compact, facilitating dense arrangement within the limited space of the needle cylinder 2, while reducing assembly complexity. When a component wears out or malfunctions, it can be quickly replaced individually without overall disassembly, greatly improving maintenance convenience. In addition, this connection method also reduces gap wobble between the two, ensuring consistency and stability of movement during knitting.

[0028] Furthermore, a needle selection tooth 121 is provided on the side of the jacquard piece 12 facing away from the needle cylinder 2. The needle selection tooth 121 is used to cooperate with the electronic needle selector to apply selective force to control the movement state of the jacquard piece 12, thereby achieving precise selection and driving of the corresponding knitting needle 11, and determining whether the knitting needle 11 participates in knitting and the specific knitting action.

[0029] Combination Figure 1 and Figure 2As can be seen, the jacquard pieces 12 in this application adopt a grouped design, specifically eight pieces per group. Within this group of jacquard pieces, the height of the needle-selecting teeth 121 on each piece is different. This differentiated structural design provides the basis for the needle selection of the electronic needle selector. During operation, the electronic needle selector identifies and acts on the needle-selecting teeth 121 of different heights within each group (i.e.,... Figure 1 Each group of jacquard pieces 12 has eight needle selection teeth 121 of different heights (a to h), which can specifically control the movement state of the corresponding jacquard piece 12, including its rising, falling, or remaining stationary. It is worth noting that each group of eight jacquard pieces 12 has a clear division in its correspondence with the knitting needles 11, with four jacquard pieces 12 cooperating with the first knitting needle 111 and the other four corresponding to the second knitting needle 112. Through this correspondence, the two types of knitting needles 11 can be controlled separately.

[0030] It should be noted that there is a one-to-one correspondence between knitting needle 11 and jacquard piece 12. Figure 1 The first stitch 111 and the second stitch 112 that are repeated in the middle are not in Figure 1 , Figure 2 As shown in the image.

[0031] Furthermore, the knitting needle 11 has a first stitch 113 on the side facing away from the needle cylinder 2, and the jacquard piece 12 has a second stitch 123 on the side facing away from the needle cylinder 2. The first stitch 113 and the second stitch 123 respectively abut against the needle path of the lower triangle 41 track. When the needle cylinder 2 drives the knitting needle 11 and the jacquard piece 12 to perform circular motion, the interaction between the stitches and the needle path of the lower triangle 41 track can guide the jacquard piece 12 to move stably along a preset trajectory, thereby driving the knitting needle 11 to complete a series of knitting actions such as crocheting and forming loops, ensuring the smoothness and precision of the knitting process.

[0032] Furthermore, a third stitch 124 is provided on the side of the jacquard piece 12 facing away from the needle cylinder 2, with the bottom end of the third stitch 124 abutting against the top end of the starting triangle 43. This specific abutting engagement is the key to the jacquard piece's starting action. When the needle cylinder 2 drives the jacquard piece 12 to rotate to the position of the starting triangle 43, the third stitch 124 slides along the top surface of the starting triangle 43. With the guidance of the thimble triangle 43, the jacquard piece 12 can obtain the driving force for upward movement, thereby driving the knitting needle 11 to rise synchronously, preparing for subsequent knitting steps such as crocheting and winding.

[0033] As described above, the electronic needle selector operates by using selection teeth 121 of different heights to select one of the different types of needles 11. This places extremely high demands on manufacturing precision and assembly alignment, making it prone to misalignment and collisions. This not only leads to fabric pattern errors and quality degradation but may also damage components such as the needles 11, jacquard pieces 12, and the needle selector, increasing equipment maintenance costs. Furthermore, in the zero-position adjustment stage of the needles 11, the existing jacquard piece assembly is highly dependent on the electronic needle selector, requiring the equipment to be powered on for calibration. This not only limits the flexibility of the adjustment process but also reduces adjustment efficiency due to the complex and time-consuming operation, severely restricting the stability of the jacquard weaving quality and the improvement of overall production efficiency.

[0034] As mentioned earlier, the electronic needle selector operates by identifying needle selection teeth 121 of different heights on the jacquard piece 12 to select a specific needle from the first needle 111 or the second needle 112. This precise control method, which relies solely on the difference in needle selection tooth height, places extremely high demands on the manufacturing precision and assembly alignment of each component—machining errors in the height of the needle selection teeth 121, relative positional deviations between the electronic needle selector and the jacquard piece 12, and even slight vibrations during the rotation of the needle cylinder 2 can all lead to errors in needle selection signal recognition.

[0035] Specifically, when manufacturing precision is insufficient or assembly alignment is off, the electronic needle selector is highly prone to misjudging the height of the needle selection teeth 121, thereby incorrectly triggering the action of non-target jacquard pieces 12, resulting in misaligned needles. Misaligned needles directly cause the knitting action of the needles 11 to deviate from the preset pattern, resulting in quality problems such as texture disorder and pattern distortion on the fabric surface, seriously affecting product quality. More seriously, if the electronic needle selector simultaneously drives adjacent or conflicting jacquard pieces 12, it will cause motion interference between the jacquard pieces 12 and the knitting needles 11, leading to needle collisions—this mechanical collision may not only bend or break the knitting needles 11 and jacquard pieces 12, but may also damage the actuators of the electronic needle selector, significantly increasing equipment maintenance costs and downtime. Furthermore, in the zero-position adjustment stage of the knitting needle 11, the existing design relies entirely on the power-on control of the electronic needle selector: the needle selector drives the jacquard plate 12 to move the knitting needle 11, and then the position information is fed back by the sensor for calibration. This method has obvious limitations: on the one hand, the adjustment requires specific conditions, and in some scenarios where there is a power outage or the electronic needle selector is damaged, the adjustment work is difficult to carry out, and there are conditional limitations; on the other hand, the adjustment process is complex, and the presence of the electronic needle selector during the adjustment process can easily lead to needle breakage, resulting in low adjustment efficiency and prolonging the equipment assembly cycle. These problems collectively lead to insufficient stability in the weaving quality of jacquard equipment and limited production efficiency, becoming a key bottleneck restricting the improvement of equipment performance.

[0036] Based on the problems existing in the jacquard sheet assembly, this application upgrades and improves it, and the improvement mainly focuses on the structure of the jacquard sheet 12, which will be described below with reference to the specific drawings.

[0037] Figure 2 This is a schematic diagram showing the structure of the jacquard piece 12 in this application corresponding to the first knitting needle 111 and the second knitting needle 112, as shown below. Figure 2 As shown, the jacquard piece 12 facing away from the needle cylinder 2 is also provided with a needle-separating tooth 122. The needle-separating tooth 122 is located below the needle-selecting tooth 121. The needle-separating tooth 122 includes a first needle-separating tooth 1221 and a second needle-separating tooth 1222. The first needle-separating tooth 1221 and the second needle-separating tooth 122 are respectively provided on the jacquard piece 12 corresponding to the first needle 111 and the second needle 112. Figure 2 For example, the first dividing tooth 1221 corresponds to the four jacquard pieces 12 with heights a, c, e, and g of the selecting tooth 121, while the second dividing tooth 1222 corresponds to the four jacquard pieces 12 with heights b, d, f, and h of the selecting tooth 121.

[0038] This newly added needle-separating tooth 122 design addresses the core problem of existing jacquard piece components from a mechanistic perspective: by differentiating the first needle-separating tooth 1221 and the second needle-separating tooth 1222, the jacquard pieces 12 can be "pre-classified" before electronic needle selection—jacquard pieces 12 belonging to the first needle 111 are identified by the first needle-separating tooth 1221, while jacquard pieces 12 belonging to the second needle 112 are distinguished by the second needle-separating tooth 1222, effectively adding a "type filtering" mechanism before the needle selection process. When the electronic needle selector is operating, it does not need to rely solely on the accurate identification of the height of the needle-separating tooth 121. It can first determine the needle category to which the target jacquard piece 12 belongs by judging the type of the needle-separating tooth 121, and then identify the height of the needle-separating tooth 121 within that category, significantly reducing the risk of mis-needle or collision needles caused by errors in the identification of a single height. Meanwhile, during needle zero-position adjustment, the jacquard pieces 12 corresponding to different types of needles 11 can be directly grouped and calibrated by using the physical differentiation of the needle teeth 122. This reduces the reliance on the power control of the electronic needle selector. Even in scenarios without a stable power supply, the adjustment object can be quickly located through mechanical structural features, simplifying the operation process, improving adjustment efficiency, and fundamentally improving the problems of unstable knitting quality and limited production efficiency of existing jacquard devices.

[0039] Furthermore, the dividing needle tooth 122 is located above the third needle foot 124. This arrangement ensures that the dividing needle tooth 122 can accurately cooperate with the relevant needle selection auxiliary structure to realize the pre-sorting function of the jacquard piece 12, and avoids interference with the contact action of the third needle foot 124 and the starting triangle 43, thus ensuring the overall coordination of the jacquard piece 12's movement.

[0040] The above are improvements to the jacquard sheet assembly in this application. As the core structure of the jacquard device, the structure of the jacquard device to which the jacquard sheet assembly acts will be described below.

[0041] Specifically, Figure 3 This is an overall structural diagram of the jacquard apparatus in this application, as shown below. Figure 3 As shown, the jacquard device includes Figure 2 The device comprises a jacquard piece assembly, a cylinder 2, an electronic needle selector (not shown) that drives the jacquard piece assembly to perform jacquard knitting actions, and a triangular unit for operating the jacquard piece assembly. The cylinder 2, as the basic supporting component, provides a stable mounting platform for the jacquard piece assembly, and its rotational motion provides the necessary power for the jacquard knitting process. The electronic needle selector, as the core control component, can precisely drive the corresponding jacquard piece 12 according to a preset knitting program by cooperating with the needle selection teeth 121 and needle distribution teeth 122 on the jacquard piece assembly, thereby achieving the selection and control of the knitting needles 11. The triangular unit is an important guiding structure for the normal operation of the jacquard piece assembly. Its track provides the movement trajectory for each stitch on the jacquard piece 12 (such as the first stitch 113, the second stitch 123, the third stitch 124, etc.), ensuring that the jacquard piece 12, driven by the cylinder 2, can complete rising and falling actions according to a preset path, thereby driving the knitting needles 11 to perform knitting operations such as hooking yarn and forming loops. These parts work together to form a complete jacquard device.

[0042] Furthermore, such as Figure 4 and Figure 5 As shown, the triangular unit includes a lower triangular 41, a pull-out triangular 42, and a starting triangular 43. The lower triangular 41 engages with the first stitch 113 of the knitting needle 11 and the second stitch 123 of the jacquard piece 12. The pull-out triangular 42 and the starting triangular 43 form a space for the circumferential movement of the bottom end of the jacquard piece 12. When the needle cylinder 2 drives the knitting needle 11 and the jacquard piece 12 to rotate, the first stitch 113 and the second stitch 123 of the knitting needle 11 and the jacquard piece 12 on the side facing away from the needle cylinder 2 will always maintain contact with the needle track of the lower triangular 41. As the needle cylinder 2 continues to rotate, the lower triangular 41 applies a guiding force to the first stitch 113 and the second stitch 123 through its specific track curve, guiding the jacquard piece 12 to move up and down along a preset path. The movement of the jacquard piece 12 can be directly transmitted to the knitting needle 11, thereby driving the knitting needle 11 to complete the corresponding up and down movement, ensuring that the knitting needle 11 can accurately reach the target position in key actions such as hooking yarn, winding yarn, and forming loops.

[0043] In some preferred embodiments of this application, to further ensure the effectiveness and efficiency of the "pre-classification" function, the jacquard device in this application further includes at least one set of push blocks 5. Each set of push blocks 5 includes a first push block 51 and a second push block 52. The height of the first push block 51 corresponds to the position of the first dividing needle tooth 1221, and the height of the second push block 52 corresponds to the position of the second dividing needle tooth 1222. The first push block 51 and the second push block 52 can respectively abut against the first dividing needle tooth 1221 and the second dividing needle tooth 1222. As a needle selection auxiliary structure, when the jacquard piece 12 rotates with the needle cylinder 2 to the position of the push block 5, the first push block 51 will contact the corresponding first dividing needle tooth 1221 and apply force to disengage the jacquard piece 12 corresponding to the first needle 111 from the running track of the starting triangle 43. Similarly, the second push block 52 will also act on the second dividing needle tooth 1222 to disengage the jacquard piece 12 corresponding to the second needle 112 from the running track of the starting triangle 43. In this way, the electronic needle selector only needs to select the jacquard piece 12 corresponding to one type of needle 11 on the current starting triangle 43 running track (that is, the jacquard piece 12 where the bottom of the current third stitch 124 abuts against the top of the starting triangle 43) in subsequent operations, without having to distinguish between the two types of needles 11. This not only greatly reduces interference factors in the needle selection process, but also further improves the accuracy and efficiency of needle selection, and strengthens the reliability of the "pre-classification" function.

[0044] Furthermore, such as Figure 4 and Figure 5 As shown in the diagram, the arrows indicate the rotation direction of the syringe 2. The first pusher block 51 and the second pusher block 52 are connected to the side of the starting triangle 43 facing away from the jacquard piece 12, and are respectively connected upstream of the starting surface 431 of the starting triangle 43 along the rotation direction of the syringe 2. Since the pusher block 5 is upstream of the starting surface 431, when the syringe 2 drives the jacquard piece 12 to rotate, the jacquard piece 12 will first contact the first pusher block 51 or the second pusher block 52. Under the action of the pusher block 5, the jacquard piece 12 will complete the disengagement action from the running track of the starting triangle 43, and then enter the area corresponding to the starting surface 431. In this way, it can be ensured that the jacquard piece 12 has completed the disengagement action required for "pre-classification" by the pusher block 5 before reaching the starting working area of ​​the starting triangle 43, avoiding motion interference caused by the jacquard piece 12 not disengaging from the track in time during the starting process, and further ensuring the orderly realization of the "pre-classification" function.

[0045] The specific structures of the first pusher block 51 and the second pusher block 52 will be described in detail below.

[0046] like Figure 4 and Figure 5 As shown, the main difference between the first push block 51 and the second push block 52 is their different heights.

[0047] Specifically, the first pusher block 51 and the second pusher block 52 each include a connecting part 53 and a working part 54. The connecting part 53 is connected to the starting triangle 43, and the working part 54 is connected to the top of the connecting part 53 and extends toward the jacquard piece 12. The end of the working part facing the jacquard piece 12 is provided with a working end face 55. The connecting part 53, as the basic structure for connecting with the starting triangle 43, can stably fix the pusher block 5 on the side of the starting triangle 43 facing away from the jacquard piece 12, ensuring that the pusher block 5 will not be displaced due to vibration or force during the operation of the jacquard device. Since the first pusher block 51 and the second pusher block 52 have different heights, the positions of their working parts 54 and working end faces 55 are also different. This allows the working end face 55 of the first pusher block 51 to accurately abut against the first dividing needle tooth 1221, and the working end face 55 of the second pusher block 52 to accurately contact the second dividing needle tooth 1222, thereby reliably completing the pushing action of different types of jacquard pieces 12 and ensuring the effective realization of the "pre-classification" function.

[0048] In some specific embodiments of this application, the difference in height between the first push block 51 and the second push block 52 is achieved by the difference in height of their corresponding connecting parts 53.

[0049] Furthermore, the working end face 55, along the rotation direction of the syringe 2, consists of a transition end face 551 and an ejection end face 552. The transition end face 551 is an inclined surface, angled towards the direction of the syringe 2, while the ejection end face 552 is a flat surface, flush with the inner side of the starting triangle 43. The inclined structure of the transition end face 551 provides a smooth transition when the jacquard piece 12 rotates with the syringe 2 and approaches the push block 5, preventing rigid collisions between the dividing teeth of the jacquard piece 12 and the working end face 55. This reduces wear on components and allows the jacquard piece 12 to transition more smoothly from its initial position to the pushed state. The flat structure of the ejection end face 552 allows the dividing teeth 122 of the jacquard piece 12 to contact the ejection end face 552 as they pass by. With the planar thrust of the ejection end face 552, the jacquard piece 12 is stably pushed away from the running track of the starting triangle 43, ensuring that the jacquard piece 12 can accurately and reliably detach from its original track.

[0050] The following will illustrate the working relationship between the jacquard piece 12, the starting triangle 43, the push block 5, and the pull-out triangle 42 during the rotation of the syringe 2, using specific illustrations.

[0051] like Figures 4-10 As shown, during the rotation of syringe 2, with Figure 4For example, when the jacquard piece 12 corresponding to the first dividing needle tooth 1221 rotates to the first push block 51, the first dividing needle tooth 1221 will first contact the transition end face 551 of the working end face 55 of the first push block 51. After a smooth transition with the guidance of the inclined surface, it will then abut against the push-out end face 552. Under this continuous force, the jacquard piece 12 corresponding to the first dividing needle tooth 1221 is smoothly pushed out from the running track of the starting triangle 43. The jacquard piece 12 corresponding to the second dividing needle tooth 1222 will not interact with the first push block 51 because the height is not matched. Therefore, it can slide naturally along the starting surface 431 of the starting triangle 43 and continue to slide along the flat surface 432 of the starting triangle 43 to the position of the pull-out triangle 42. During the stage when only the jacquard piece 12 corresponding to the second dividing needle tooth 1222 slides on the running track of the starting triangle 43, the electronic needle selector can complete the accurate selection of the jacquard piece 12 without interference. When the jacquard piece 12 corresponding to the first dividing needle tooth 1221 rotates to the position of the pull-out triangle 42, the pull-out triangle 42 will apply a pulling force to pull it back to the flat surface 432 of the starting triangle 43. At this time, the jacquard piece 12 corresponding to the first dividing needle tooth 1221 and the second dividing needle tooth 1222 merge and continue to slide along the flat surface 432 of the starting triangle 43 to the position of the second push block 52. Here, the second dividing needle tooth 1222 sequentially contacts the transition end face 551 and the ejection end face 552 of the working end face 55 of the second push block 52, and is then ejected from the running track of the starting triangle 43. Meanwhile, the jacquard piece 12 corresponding to the first dividing needle tooth 1221, since it does not interact with the second push block 52, slides smoothly along the starting surface 431 of the starting triangle 43, and continues to slide along the flat surface 432 of the starting triangle 43 to the position of the pull-out triangle 42. During the movement track of the starting triangle 43, only the jacquard piece 12 corresponding to the first dividing needle tooth 1221 slides, and the electronic needle selector completes the selection of the jacquard piece 12. When the jacquard piece 12 corresponding to the second dividing needle tooth 1222 rotates to the position of the pull-out triangle 42, the pull-out triangle 42 pulls it out onto the flat surface 432 of the starting triangle 43, thus completing a complete cycle.

[0052] The above describes the movement and needle selection of jacquard pieces 12 corresponding to different needle teeth during the rotation of the cylinder 2 when a set of push blocks 5 is set. However, it is conceivable that the number of push blocks 5 is not limited to one set, and multiple sets can be set according to actual knitting needs. When there are multiple sets of push blocks 5, multiple first push blocks 51 and second push blocks 52 will be set in an alternating manner. This alternating setting can further improve the efficiency and flexibility of "pre-classification" and needle selection. During the continuous rotation of the cylinder 2, each set of push blocks 5 can sequentially classify the jacquard pieces 12 that pass by, so that different types of jacquard pieces 12 can be orderly pushed out or retained on the running track of the starting triangle 43 in multiple stages. The electronic needle selector can also complete the selection of different types of jacquard pieces 12 in more independent stages, thereby better adapting to the needs of complex pattern knitting and improving the overall working efficiency and knitting quality stability of the jacquard device. Furthermore, the distance between the first push block 51 and the second push block 52 is determined based on the design of the knitting machine's layout and the specific indexing position.

[0053] In a specific embodiment of this application, to verify the practical application effect of the technical solution, a 27-inch circular knitting machine was used as a typical application object for testing. Table 1 clearly presents the correspondence between different knitting patterns and their corresponding angles and arc lengths. The arc length has a clear physical meaning—it directly corresponds to the distance between the first push block 51 and the second push block 52 under that knitting pattern. This is because the first push block 51 and the second push block 52 are spaced apart and arranged circumferentially on the circular track of the needle cylinder 2, exactly at both ends of the same arc length. The size of their distance directly determines the measurement range of the arc length. Through the data in Table 1, the push block layout in the theoretical design can be intuitively correlated with the parameter settings in actual production, providing a precise quantitative basis for subsequent debugging and optimization, ensuring that the pre-classification function can be stably and efficiently implemented under the knitting requirements of different knitting patterns.

[0054] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
