Warp knitting machine that can freely switch between wireless jacquard combs and floor combs
[0001] This application claims priority to Chinese patent applications filed on January 7, 2025, with application numbers 202510024185.8 and 202520032866.4, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of warp knitting machine technology, such as a warp knitting machine that can freely switch between wireless Jacquard combs and floor combs. Background Technology
[0003] The warp knitting machines in related technologies include jacquard machines and ordinary machines. Jacquard machines can only weave shoe uppers with jacquard, while ordinary machines can only weave ordinary mesh fabrics. Jacquard machines can be single jacquard machines, double jacquard machines, or triple jacquard machines. Single jacquard machines can only weave single jacquard products, while double or triple jacquard machines can only weave jacquard weaves according to the jacquard comb and cannot weave ground comb textures other than jacquard.
[0004] The incompatibility between the different types of warp knitting machines mentioned above prevents them from being used for multiple purposes, indirectly increasing the weaving costs for manufacturers. Furthermore, changing the type of warp knitting machine to produce also increases labor costs associated with machine modification and yarn threading, resulting in low production efficiency. Additionally, different needle count machines (22E, 24E, 12E, etc.) require repeated machine changes, which is detrimental to efficient production. Summary of the Invention

[0032] As shown in Figures 1 and 2, this application provides a warp knitting machine that can freely switch between wireless Jacquard combs and ground combs, including: a warp knitting machine body 1, a connector 2, at least one of a wireless Jacquard comb assembly 3 or a ground comb assembly 4; the connector 2 is installed on the warp knitting machine body 1 and is configured to be connected and assembled with at least one of the wireless Jacquard comb assembly 3 or the ground comb assembly 4 through a connecting component 5.
[0033] This application uses connecting component 5 to detachably install the wireless jacquard comb component 3 and the ground comb comb component 4 onto the warp knitting machine body 1, facilitating the replacement of the comb components according to actual needs. Specifically, with a warp knitting machine, the wireless jacquard comb component 3 can be assembled on the connector 2 as needed. The power cord is connected to the wireless jacquard comb component 3, and the host computer controls the jacquard comb to perform corresponding knitting actions, resulting in a more complex pattern on the shoe upper. When jacquard is not needed, the wireless jacquard comb component 3 can be removed and replaced with the ground comb comb component 4. The resulting shoe upper is a jacquard-free upper, controlled by digital codes, with a simpler pattern.
[0034] In summary, the warp knitting machine provided in this application is compatible and can be used for multiple purposes, allowing manufacturers to purchase fewer devices to meet production needs, i.e., to switch the comb bar assembly according to orders for production and processing.
[0035] In one embodiment, as shown in Figures 3, 7, and 9, the insertion frame 2 includes a comb cradle 21 and a comb hanger seat 22. The comb cradle 21 is installed on the warp knitting machine body 1, and the comb hanger seat 22 can be locked to the comb cradle 21 by bolts.
[0036] As shown in Figures 3, 7, and 9, the connector frame 2 includes a comb wobbler 21 and a comb hanger seat 22. During weaving, the comb wobbler 21 drives the comb hanger seat 22 to swing. The comb wobbler 21 can be a fan-shaped structure, and multiple comb hanger seats 22 are fixed to the comb wobbler 21 along the radial direction of the fan-shaped structure.
[0037] In one embodiment, as shown in FIG3, the connecting component 5 includes a slide rod 54 and a plug interface 55. The slide rod 54 may be a cylindrical structure. During connection, the slide rod 54 is inserted into the plug interface 55 to install the wireless Jacquard comb assembly 3 or the ground comb comb assembly 4 onto the warp knitting machine body 1, or the slide rod 54 is pulled out from the plug interface 55 to remove the wireless Jacquard comb assembly 3 or the ground comb comb assembly 4 from the warp knitting machine body 1. The insertion and connection are convenient, and the wireless Jacquard comb assembly 3 or the ground comb comb assembly 4 can be freely assembled onto the warp knitting machine body 1. Moreover, the removed wireless Jacquard comb assembly 3 or the ground comb comb assembly 4 is easy to thread.
[0038] In one embodiment, as shown in Figures 1 and 2, the wireless Jacquard comb assembly 3 or the ground comb assembly 4 includes a comb hanger 52 and a comb frame 53, with the bottom of the comb hanger 52 being locked to the comb frame 53.
[0039] A sliding rod 54 can be provided on one of the comb hanger base 22 and the comb hanger 52, and an interface 55 can be provided on the other. As shown in Figures 2 and 4, two interfaces 55 are provided along the height direction of the comb hanger 52, and two sliding rods 54 are correspondingly provided on the comb hanger base 22. The sliding rods 54 are inserted into the interfaces 55 to connect and fix the comb hanger base 22 and the comb hanger 52, thereby connecting the wireless Jacquard comb assembly 3 or the ground comb assembly 4 to the connector 2.
[0040] It is understandable that this application provides an insertion interface 55 that cooperates with the slide bar 54 on the comb hanger 52 of the wireless jacquard comb assembly 3 or the ground comb comb assembly 4, and provides the slide bar 54 on the insertion frame 2 of the warp knitting machine body 1. This is because if the slide bar 54 is provided on the comb assembly, there are many yarns when the yarn is being threaded, and the protruding structure of the slide bar 54 may affect the yarn from passing through the comb, and the yarn is more likely to be contaminated.
[0041] In one embodiment, as shown in FIG3, two insertion interfaces 55 are provided on the comb hanger base 22 along its height direction, and two corresponding slide rods 54 are provided on the comb hanger 52. Each insertion interface 55 is provided with a bearing 56. The slide rod 54 is inserted into the corresponding insertion interface 55 and sleeved on the bearing 56. The bearing 56 and the slide rod 54 are designed to be detachable, which facilitates maintenance and repair, and the detachable design makes the bearing 56 and the slide rod 54 suitable for different types of comb assemblies.
[0042] In one embodiment, as shown in Figures 4-7, a rubber layer 513 is fitted onto the surface of the slide rod 54 to form a pin 51. When the pin 51 is inserted into the insertion interface 55, the rubber layer 513 is compressed and abuts against the inner wall of the insertion interface 55. The slide rod 54 and the pin 51 have a nested structure. The slide rod 54 may have both ends protruding from the ends of the pin 51, or one end of the slide rod 54 may protrude from one end of the pin 51 while the other end remains inside the pin 51.
[0043] In one embodiment, a plurality of retaining balls 511 are distributed on the rubber layer 513. The retaining balls 511 are placed on the inner side of the rubber layer 513 and connected to a spring 512. When the pin 51 is inserted into the insertion interface 55, the retaining balls 511 are squeezed and abut against the inner wall of the insertion interface 55.
[0044] This application increases friction when the slide rod 54 is inserted into the insertion interface 55 by providing a rubber layer 513 and / or a retaining ball 511 on the slide rod 54, making the slide rod 54 less likely to come out of the insertion interface 55 and the connection more secure.
[0045] In one embodiment, a plurality of plug-in frames 2 are spaced apart on the warp knitting machine body 1 along the length direction of the wireless jacquard comb assembly 3 or the ground comb comb assembly 4. A plurality of comb hanger seats 22 are connected to each comb cradle 21. A plurality of comb hangers 52 are spaced apart on the comb frame 53 of at least one ground comb comb assembly 4 and the comb frame 53 of at least one wireless jacquard comb assembly 3 to be plugged into and assembled with the corresponding plug-in frame 2.
[0046] Figure 4 illustrates a connector frame 2, which includes a comb cradle 21 and two comb hanger seats 22. The two comb hanger seats 22 can be connected to a wireless Jacquard comb assembly 3 and a ground comb assembly 4, respectively; or both comb hanger seats 22 can be connected to wireless Jacquard comb assemblies 3; or both comb hanger seats 22 can be connected to ground comb assembly 4. In other words, there are multiple combinations of wireless Jacquard comb assemblies 3 and ground comb assemblies 4 connected to a single connector frame 2, improving the utilization rate of the warp knitting machine. Each comb hanger seat 22 has two sliding rods 54 along its height. A comb assembly's comb hanger 52 has two corresponding insertion interfaces 55. The two sliding rods 54 are inserted into the two insertion interfaces 55 respectively, connecting the comb assembly to the connector frame 2. As shown in Figure 2, a comb assembly is provided with multiple comb hangers 52 spaced apart on the comb frame 53. In conjunction with Figures 2 and 4, each comb hanger 52 in Figure 2 is connected to a comb hanger seat 22 on a plug-in frame 2.
[0047] In one embodiment, as shown in FIG8, the wireless jacquard comb assembly 3 or the floor comb assembly 4 further includes an aluminum angle 57, which is locked to the top of a plurality of comb hangers 52.
[0048] As shown in Figure 9, the wireless jacquard comb assembly 3 includes a wireless jacquard comb 12, which is equipped with multiple wireless jacquard pins. Each wireless jacquard pin is equipped with a piezoelectric ceramic plate, which triggers the wireless jacquard pin to be energized.
[0049] In one embodiment, the warp knitting machine provided in this application further includes a control box and a power cord 6. The control box is wirelessly connected to the wireless jacquard needles, and the power cord 6 is electrically connected to the piezoelectric ceramic sheet.
[0050] The power cord 6 can be connected to a power source and is electrically connected to the piezoelectric ceramic sheet. When powered on, the piezoelectric ceramic sheet triggers the wireless Jacquard needle to power on, and the control box can control the wireless Jacquard needle to perform knitting actions according to the set commands.
[0051] In one embodiment, the wireless Jacquard comb assembly 3 further includes a conventional comb 11 on which yarn guides are installed. The conventional comb 11 and the wireless Jacquard comb 12 on the wireless Jacquard comb assembly 3 are detachable and can be used interchangeably or in combination.
[0052] In one embodiment, the wireless jacquard comb assembly 3 can also be used as a regular floor comb assembly depending on whether it is powered on or off.
[0053] The warp knitting machine in this application, which allows for free switching between wireless Jacquard combs and ground combs, is a double or triple Jacquard device with 22, 24, 28, or 32 needles, and the needle count can be arbitrarily switched in different multiples. It uses 1 / 2 or 1 / 3 of the open guide bars to weave different styles of fabrics, enabling free switching between 24-needle Jacquard combs and 12-needle Jacquard combs, as well as 24-needle ground combs and 12-needle ground combs on the warp knitting machine.
[0054] In one embodiment, the jacquard device has 24 needles. By switching between a 12-needle ground comb and a wireless jacquard comb, 12 needles are woven on the face and 24 needles are woven on the bottom. That is, the original device comb has 24 needles, but the knitting design requires 12 needles. By switching to the 12-needle ground comb and wireless jacquard comb, 12 needles are woven on the face and 24 needles are woven on the bottom.
[0055] The different multipliers are based on a base of 2 for switching. That is, the needle blocks in the warp knitting equipment are configured with a multiplier based on a needle pitch of 2 needles per inch. For example, 8 needles, 12 needles, and 22 needles are 4 times, 6 times, and 11 times, respectively. In the field of footwear and apparel knitting, 24 needles, 28 needles, and 32 needles are 12 times, 14 times, and 16 times, respectively. Similarly, it can also be 34 needles at 17 times, 36 needles at 18 times, etc.
