Description

Technical Field

[0001] This application belongs to the field of knitting machine accessories, specifically relating to a jacquard device and knitting structure for a loop cutting machine. Background Technology

[0002] In the field of textile machinery, the ribbing cutter is widely used in the production of various knitted fabrics due to its unique weaving process and flexible production capacity. However, while the original jacquard structure of the ribbing cutter can effectively complete the weaving task, there are still some problems that cannot be ignored.

[0003] Firstly, from a structural perspective, the original jacquard structure of the cutting machine is relatively complex. This complexity not only increases the difficulty of assembly but also poses a higher challenge to the skills required of the operators. During assembly, even the slightest error can cause the jacquard structure to malfunction, thereby affecting weaving efficiency and quality.

[0004] Secondly, the original jacquard structure requires extremely high assembly precision. Because the fit between the jacquard pieces and the cams needs to be extremely precise, any deviation in assembly can lead to poor jacquard results or equipment malfunction. This high precision requirement not only increases production costs but also limits the expansion of production scale.

[0005] Furthermore, the excessively small mechanical clearance is another significant problem with the original jacquard structure of the ribbing machine. While this design improves the compactness and stability of the equipment to some extent, it hinders the effective removal of fiber debris. During the weaving process, fiber debris easily accumulates between the jacquard pieces and the cams, leading to damage to the jacquard pieces or excessive wear on the cams. This not only seriously affects the quality of the fabric but also increases the difficulty and cost of equipment maintenance.

[0006] More seriously, the accumulation of fiber debris between the jacquard pieces and the trowels can trigger a series of chain reactions. For example, damaged jacquard pieces may cause the weave pattern to become disordered or incomplete, thus affecting the overall aesthetics and market competitiveness of the product. Excessive wear on the trowels can lead to a decline in equipment performance and even cause more serious equipment failures.

[0007] In conclusion, while the original jacquard structure of the ribbing cutter has a certain weaving capability, its complexity, high precision requirements, and excessively small mechanical clearances severely limit its application in actual production. Therefore, it is necessary to improve and optimize the jacquard structure of the ribbing cutter to increase its production efficiency, reduce maintenance costs, and improve fabric quality. Utility Model Content

[0008] This application aims to provide a jacquard device and its weaving structure for a cutting machine that is simple in structure, has low precision requirements, low maintenance costs, and can achieve high-efficiency production and high fabric quality.

[0009] The embodiments of this application can be implemented through the following technical solutions:

[0010] A jacquard device is housed in the needle groove of a needle cylinder and abuts against a knitting triangle on the side facing away from the needle cylinder. The jacquard device includes a cutter and a jacquard piece arranged from top to bottom, and the cutter and the jacquard piece are in contact.

[0011] The cutting blade includes a first stitch, and the jacquard piece includes a second stitch and a third stitch. The first stitch, the second stitch, and the third stitch are all positioned away from the needle cylinder and protrude from the surface of the needle cylinder. The first stitch, the second stitch, and the third stitch all abut against the knitting triangle.

[0012] Furthermore, the knitting triangle includes a cutting triangle, a pressing triangle, and a starting triangle arranged from top to bottom, wherein the cutting triangle, the pressing triangle, and the starting triangle respectively cooperate and abut with the first stitch, the second stitch, and the third stitch.

[0013] Furthermore, the cutting triangle is provided with a first track, which abuts against the first pin, and the first track is used to guide the movement of the cutting blade;

[0014] The pressure needle triangle has a second track, which abuts against the second needle foot. The second track is used to limit the rising height of the jacquard piece.

[0015] The top of the starting triangle abuts against the bottom of the third stitch, and its top is set as a straight or non-straight advance track, which is used to advance the jacquard piece.

[0016] The shapes of the first track, the second track, and the propulsion track are matched.

[0017] Furthermore, the knitting triangle also includes a pull-out triangle, which is connected to the side of the starting triangle facing the jacquard device.

[0018] Furthermore, a pull-out track is formed between the pull-out triangle and the starting triangle to accommodate and limit the lower part of the jacquard piece.

[0019] A knitting structure includes the jacquard device, the needle cylinder, the knitting triangle, and the electronic needle selector;

[0020] The jacquard device is housed in the needle groove of the needle cylinder, and its side facing away from the needle cylinder abuts against the knitting triangle. The needle selection foot of the jacquard device is connected to the electronic needle selector.

[0021] The jacquard device and weaving structure for a ring cutting machine provided in the embodiments of this application have at least the following beneficial effects:

[0022] The cutter and jacquard piece in the jacquard device of this application can operate independently. The cutter can be linked by directly acting on the jacquard piece, eliminating the need for a traditional center frame for motion transmission and restriction. This design not only simplifies the original combination structure of "traditional jacquard piece + center frame + cutter" into a new structure of "new jacquard piece + cutter," but also significantly improves operating efficiency, reduces malfunctions, and lowers maintenance difficulty while ensuring compliance with fabric weaving process requirements. Furthermore, the new jacquard device has lower requirements for assembly precision, allowing for more flexible gaps between the jacquard piece and the knitting triangle, effectively reducing fiber debris accumulation, further lowering operating and maintenance costs and time, and improving weaving production efficiency.

[0033] The present application will now be further described based on preferred embodiments and with reference to the accompanying drawings.

[0034] 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.

[0035] 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.

[0036] The jacquard device 3 is a key component in the ribbing machine for realizing pattern knitting. It is housed within the needle groove 11 of the machine's cylinder 1, and its side facing away from the cylinder 1 abuts against the knitting cam. During the operation of the ribbing machine, the cylinder 1 moves in a circular motion, driving the jacquard device 3 to move along the needle groove 11. Simultaneously, guided by the knitting cam, the jacquard device 3 performs precise lifting, lowering, and lateral movement to achieve yarn knitting and / or cutting.

[0037] Figure 2 This diagram shows the overall structure of an existing jacquard device 3 for a loop cutting machine, which is connected to a knitting triangle and an electronic needle selector 4. Figure 1 As shown, the jacquard device 3 includes a cutter 31, a center stile 33, and a jacquard piece 32 arranged from top to bottom. The cutter 31 can contact the center stile 33. The center stile receiving groove at the top of the jacquard piece 32 can accommodate and fix the bottom end of the center stile, so as to allow the center stile 33 to slide or rotate within the jacquard piece 32.

[0038] like Figure 2As shown, the knitting structure includes a cylinder 1, a jacquard device 3, and knitting triangles. The jacquard device 3 is a key component of the knitting structure, and the knitting triangles include a cutter triangle 21, a center tassel triangle 25, and a pull-out triangle 24. These triangles are respectively provided with a first track 211, a third track, and a pull-out track that engage with the cutter 31, the center tassel 33, and the jacquard piece 32. On the side of the cutter 31, the center tassel 33, and the jacquard piece 32 facing the knitting triangle, there are first stitches 311, fourth stitches 331, and connecting pieces that engage with these tracks. The pull-out track and connecting pieces are used to pull out unselected jacquard pieces 32.

[0039] During jacquard weaving on the cutting machine, the force exerted on the jacquard piece 32 determines its motion. When the jacquard piece 32 is subjected to force and experiences radial displacement, the center support piece 33 held above it and the cutter 31 in contact with the center support piece 33 will fall within the needle groove 11 and can run along the horizontal areas of the first track 211 and the third track. When the jacquard piece 32 is not subjected to force and does not experience radial displacement, the center support piece 33 and the cutter 31 will rise within the needle groove 11 and can run along the inclined areas of the first track 211 and the third track.

[0040] Furthermore, the direction of movement of the cutter 31 also affects its interaction with the center taper 33. When the cutter 31 moves horizontally, the center taper 33 contacts the cutter 31 and applies an upward pushing force. When the direction of movement of the cutter 31 needs to change to an inclined upward slope, the center taper 33 begins to separate from the cutter 31. After the cutter 31 moves beyond the highest point of the first track 211, it gradually falls back under the action of the first needle foot 311 until it re-contacts the center taper 33 below the needle groove 11.

[0041] Furthermore, such as Figure 2 As shown, the knitting structure also includes an electronic needle selector 4. Multiple needle selection feet 323 are provided on the side of the jacquard piece 32 facing the knitting triangle, and these feet 323 are engaged with the electronic needle selector 4. The electronic needle selector 4 typically consists of multiple levels of parallel needle selection blades and electrical needle selection components. The needle selection blades have an upward and downward movement. Each level of needle selection blade is controlled by its corresponding electrical component and can swing up and down to control the pulling out and pushing in of the jacquard piece 32.

[0042] Specifically, when the needle blade is in the upward-pulling state, the jacquard piece 32 is in the pushed-in state; when the needle blade is in the downward-pulling state, the jacquard piece 32 is in the pulled-out state.

[0043] This section will Figure 2 The working principle of the existing jacquard device 3 will be explained in detail with reference to specific embodiments.

[0044] Figure 4 , Figure 5 and Figure 8 They are shown respectively Figure 2 The cross-sectional view of the jacquard piece 32 in the pulled-out and pushed-in states, in conjunction with the needle cylinder 1 and the knitting triangle, and the side view of the corresponding knitting triangle, are shown below. Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, its coordinated actions mainly consist of the following processes:

[0045] (1) Initial state: All jacquard pieces 32 first pass through the pull-out triangle 24 during operation. After passing through the pull-out triangle 24, all jacquard pieces 32 are in the pulled-out state, and at this time they are in the state of waiting for needle selection.

[0046] (2) Needle selection process: Subsequently, the jacquard pieces 32 continue to run and pass through the electronic needle selector 4. The electronic needle selector 4 determines which jacquard pieces 32 need to remain in the pulled-out state and which need to be switched back to the pushed-in state based on the state of its blades.

[0047] (3) Correlation of the center taper 33: The running state of the jacquard piece 32 (i.e., whether it is selected) is related to the running trajectory of the center taper 33. Specifically, the selected jacquard piece 32 (keeping in the pulled-out state) will guide the center taper 33 to move along a specific trajectory.

[0048] (4) Correlation of the cutter 31: Finally, the running trajectory of the center plate 33 is further correlated with the running trajectory of the cutter 31. The cutter 31 performs the necessary cutting actions during the knitting process according to the instructions of the center plate 33.

[0049] In some specific embodiments, such as Figure 5 and Figure 8 As shown, when the needle blade is in the upward-pulling state, the jacquard blade 32 is in the pushed-in state, and the central taper 33 is also pushed in, and its running trajectory is as follows. Figure 8 In the triangular truss 25, 1a, the cutter 31 will run along its original trajectory, that is, the trajectory of the cutter 31 is as follows: Figure 8 In the cleaver triangle 21, 1a.

[0050] In some other specific embodiments, such as Figure 4 and Figure 8 As shown, when the needle blade is in the downward-pulling state, the jacquard blade 32 is in the pulled-out state, and the central taper 33 is also pulled out. Their trajectory is as follows: Figure 8 In the center of the triangle 25, 1b, the cutter 31 is pushed by the center plate 33, that is, the movement trajectory of the cutter 31 is as follows: Figure 8 In the triangle 21 of the cutting tool, 1b.

[0051] As can be seen from the above description, although the existing jacquard device 3 and its weaving structure can complete the weaving task, they have obvious shortcomings. Specifically, its structure is slightly complex and has excessively high requirements for assembly precision. In addition, the excessively small mechanical clearance design is not conducive to the effective discharge of fiber debris, often leading to the accumulation of fiber debris between the jacquard piece 32 and the knitting triangle. This not only damages the jacquard piece 32 or causes excessive wear on the knitting triangle, but also seriously affects the fabric quality, increases the difficulty of maintenance, and ultimately restricts the improvement of weaving production efficiency.

[0052] In addition, from Figure 4 and Figure 5 It can also be seen that the existing jacquard device 3 is pulled out or pushed in with the first base point A and the second base point B as the base points during operation, which also illustrates the above-mentioned problems of the existing jacquard device.

[0053] Based on the problems of existing jacquard devices 3, we innovatively propose a new type of jacquard device 3 and weaving structure. Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 9 The diagram shows the overall structure of the new knitting structure and the diagrams of the various dimensions in which the new jacquard device 3 is connected to the knitting triangle and the electronic needle selector 4.

[0054] Next, we will introduce the core structure, the jacquard device 3.

[0055] like Figure 3 As shown, the novel jacquard device 3 includes a cutter 31 and a jacquard piece 32 arranged sequentially from top to bottom, and the cutter 31 and the jacquard piece 32 can contact each other. The cutter 31 and the jacquard piece 32 in the novel jacquard device 3 can operate independently. The cutter 31 can be linked by directly acting on the jacquard piece 32, without relying on the traditional center support plate 33 for motion transmission and restriction.

[0056] Therefore, this design not only simplifies the original combination structure of "traditional jacquard piece + center clip + cutter" and optimizes it into a new structure of "new jacquard piece + cutter," but also significantly improves operating efficiency, reduces malfunctions, and lowers maintenance difficulty while ensuring that the requirements of fabric weaving process are met. Furthermore, the new jacquard device 3 has lower requirements for assembly precision, making the gap between the jacquard piece 32 and the knitting triangle more flexible, effectively reducing the accumulation of fiber debris, further reducing operating and maintenance costs and time, and improving weaving production efficiency.

[0057] Practical experience has shown that the operating efficiency of the ring cutter has increased by approximately 30% to 50% after using the new jacquard device 3.

[0058] Furthermore, such as Figure 3 , Figure 6 and Figure 7 As shown, the cutter 31 includes a first needle 311, and the jacquard piece 32 includes a second needle 321 and a third needle 322. The first needle 311, second needle 321, and third needle 322 are all positioned away from the needle cylinder 1 and protrude from its surface. Each of these needles abuts against the knitting cam. During the operation of the loop-cutting machine, the needle cylinder 1 undergoes circular motion, and these needles, all positioned away from the needle cylinder 1 and protruding from its surface, are engaged with it. Under the action of the knitting cam, the first needle 311, second needle 321, and third needle 322 not only drive the jacquard piece 32 to move, but also, through their coordinated interaction, determine the movement trajectory of the cutter 31.

[0059] Furthermore, such as Figure 3 , Figure 6 and Figure 7 As shown, the needle triangles include a cutting triangle 21, a pressing triangle 22, and a starting triangle 23 arranged from top to bottom. The cutting triangle 21, the pressing triangle 22, and the starting triangle 23 respectively cooperate and abut with the first needle 311, the second needle 321, and the third needle 322.

[0060] The cutting triangle 21, the pressing triangle 22, and the starting triangle 23 exhibit a certain degree of diversity in their structural design. They can be integrated into a single triangular body to form an integral structure; or they can be designed separately, with each triangle having an independent triangular body. In some preferred embodiments of this application, such as... Figure 3 As shown, the cutting triangle 21, the pressing triangle 22, and the starting triangle 23 adopt a split design, which brings significant advantages such as flexible and convenient assembly, easy disassembly, and convenient maintenance.

[0061] Furthermore, such as Figure 3 and Figure 9 As shown, the cutting triangle 21 has a first track 211, which abuts against the first pin 311. The first track 211 is used to guide the movement of the cutting blade 31, so as to ensure that the cutting blade 31 can perform precise cutting operations according to the predetermined path, and also greatly improves the stability and efficiency of the entire operation process.

[0062] Furthermore, such as Figure 3 and Figure 9 As shown, the top of the starting triangle 23 abuts against the bottom of the third stitch 322, and its top is set as a straight or non-straight advance track 231. The advance track 231 is used to effectively advance the jacquard piece 32. With the cooperation of precision devices such as the electronic needle selector 4, the jacquard piece 32, as a component that directly interacts with these devices, can move smoothly and accurately along the advance track 231 under its precise drive.

[0063] Furthermore, such as Figure 3 and Figure 9 As shown, the pressure cam 22 has a second track 221, which abuts against the second needle foot 321. The second track 221 is used to precisely limit the rising height of the jacquard piece 32, effectively preventing the jacquard piece 32 from deviating too high or too low when it abuts against the cutter 31 during its reciprocating motion in the vertical direction. This precise limiting ensures that the trajectory of the cutter 31 is not disturbed, thereby guaranteeing the pattern accuracy and overall quality of the jacquard fabric, and providing a solid guarantee for the stable operation and high-quality output of the cutting machine.

[0064] In addition, such as Figure 9 As shown, in order to ensure the fit between the cutter 31, the jacquard piece 32 and the first track 211, the second track 221 and the propulsion track 231, the shapes of the first track 211, the second track 221 and the propulsion track 231 are matched with each other.

[0065] Additionally, it is worth noting that, such as Figure 9 As shown, to ensure a perfect fit between the cutter 31, jacquard blade 32, and the first track 211, second track 221, and propulsion track 231, the shapes of these tracks are designed and manufactured to match each other. This matching is reflected not only in their geometry but also in their function and operation. Through this design, the cutter 31 can move precisely and stably along the first track 211, while the jacquard blade 32, under the limiting action of the second track 221 and the guidance of the propulsion track 231, can achieve precise rising, falling, and moving. This mutual matching and coordinated work between the tracks provides a solid foundation for the stable operation and high-efficiency production of the entire ring cutting machine.

[0066] Furthermore, with Figure 2 The structures are similar, such as Figure 3 As shown, the jacquard device 3 for the ring cutting machine in this application also has multiple needle selection pins 323 on the jacquard piece 32. The difference from the existing jacquard device 3 is that the setting position is different. The needle selection pin 323 is located between the second needle pin 321 and the third needle pin 322, and the needle selection pin 323 is connected to the electronic needle selector 4.

[0067] The following will Figure 3 The working principle of the jacquard device 3 in this application will be described in detail with reference to specific embodiments.

[0068] Figure 6 , Figure 7 and Figure 9 They are shown respectively Figure 3The cross-sectional view of the jacquard piece 32 in the pulled-out and pushed-in states, in conjunction with the needle cylinder 1 and the knitting triangle, and the side view of the corresponding knitting triangle, are shown below. Figure 6 , Figure 7 and Figure 9 As shown, its coordinated actions mainly consist of the following processes:

[0069] (1) Initial state: All jacquard pieces 32 first pass through the pull-out triangle 24 during operation. After passing through the pull-out triangle 24, all jacquard pieces 32 are in the pulled-out state, and at this time they are in the state of waiting for needle selection.

[0070] (2) Needle selection process: Subsequently, the jacquard pieces 32 continue to run and pass through the electronic needle selector 4. The electronic needle selector 4 determines which jacquard pieces 32 need to remain in the pulled-out state and which need to be switched back to the pushed-in state based on the state of its blades.

[0071] (3) Correlation of the cutter 31: The running state of the jacquard piece 32 (i.e. whether it is selected) is directly related to the running trajectory of the cutter 31. Specifically, the selected jacquard piece 32 (keeping pulled out) will cause the cutter 31 to move along a specific trajectory to perform the necessary cutting action.

[0072] In some specific embodiments of this application, such as Figure 7 and Figure 9 As shown, when the needle blade is in the upward-pulling state, the jacquard blade 32 is in the pushed-in state, and its running trajectory is as follows: Figure 9 In the starting triangle 23, 2a, the cutter 31 will run along the original track, that is, the running trajectory of the cutter 31 is as follows: Figure 9 In the cleaver triangle 21, 2a.

[0073] In other specific embodiments of this application, such as Figure 6 and Figure 9 As shown, when the needle blade is in the downward-pulling state, the jacquard blade 32 is in the pulled-out state, and its running trajectory is as follows: Figure 9 In the starting triangle 23, 2b, the cutting blade 31 is pushed by the jacquard piece 32, that is, the trajectory of the cutting blade 31 is as follows: Figure 9 In the triangle 21 of the cutting tool, 2b.

[0074] In addition, such as Figure 6 and Figure 7 As shown, the jacquard device 3 in this application operates by using the third base point C as the sole base point for pulling out or pushing in during operation. Compared with existing jacquard devices 3, this design feature highlights its advantages from the perspective of the operating base point, namely, stable and efficient operation can be achieved with only one base point. This not only simplifies the operation process but also further demonstrates the optimization and improvement of the new jacquard device 3 in terms of structural design and operating efficiency.

[0075] Furthermore, with Figure 2 The structures are similar, such as Figure 3 As shown, the knitting triangle in this application also includes a pull-out triangle 24, which differs from the existing jacquard device 3 in that its setting position is different. The pull-out triangle 24 is connected to the side of the starting triangle 23 facing the jacquard device 3.

[0076] Furthermore, a pull-out track is formed between the pull-out triangle 24 and the starting triangle 23 to accommodate and limit the lower part of the jacquard piece 32. During the knitting process, the jacquard piece 32 moves according to the instructions of the electronic needle selector 4 or other driving device. At this time, the lower part of the jacquard piece 32 moves along the pull-out track formed between the pull-out triangle 24 and the starting triangle 23.

[0077] 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.
