Description

Technical Field

[0001] This utility model relates to the field of jacquard yarn frame technology, specifically a warp-knitted jacquard intelligent yarn frame. Background Technology

[0002] Traditional warp-knitting jacquard frames are designed with a fixed structure, which brings many inconveniences to yarn changes. Each yarn change requires operators to spend a significant amount of time and effort, increasing labor costs and reducing production efficiency. More importantly, this design makes yarn changes extremely inconvenient, increasing operational difficulty and placing higher demands on the knitting process. Furthermore, the fixed frame design makes yarn changes extremely cumbersome, further hindering the smooth progress of knitting operations. Crucially, traditional frames use a passive yarn feeding method, lacking the yarn's active adjustment capability during knitting, leading to extremely high requirements for the knitting process. Especially for highly elastic yarns, this passive feeding method easily causes reduced yarn elasticity or stretching deformation, severely affecting the quality and performance of the fabric. The passive yarn feeding method of traditional frames can easily lead to decreased yarn elasticity or irreversible stretching deformation, thus affecting the quality and performance of the fabric. Therefore, traditional warp-knitting jacquard frames are inadequate for the demands of modern textile industry for efficient and high-quality production, and are unable to meet the complex and ever-changing production process requirements. Traditional warp-knitted jacquard frames are inadequate for handling highly elastic and special yarns, failing to meet the demands of modern textile industry for efficient and high-quality production. Utility Model Content

[0003] This invention provides a warp-knitted Jacquard intelligent yarn frame, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A warp-knitted jacquard intelligent yarn frame includes a yarn frame frame, yarn hanging rods, yarn rod driving devices, and tension control devices. Several yarn hanging rods are arranged on the yarn frame frame. Each yarn hanging rod is independently controlled to rotate by the yarn rod driving device. Each yarn hanging rod is equipped with a tension control device. Each tension control device installed in the yarn hanging rod is electrically connected to the corresponding yarn rod driving device to independently control the rotation speed of each yarn hanging rod.

[0006] In some embodiments, the tension control device includes at least one stress retainer that extends through the surface of the yarn hanging rod, as well as a piston plate, an air pressure sensor, and control components disposed inside the yarn hanging rod.

[0007] In some embodiments, one end of the stress snap ring is fixedly connected to the surface of the yarn hanging rod, and the other end is a movable end connected to the piston plate inside the yarn hanging rod; an air pressure sensor is also provided in the sealed space inside the yarn hanging rod isolated by the piston plate, and the air pressure sensor is electrically connected to the control component connected to the piston plate and the yarn frame drive device.

[0008] In some implementations, it also includes several yarn collecting plates mounted on the yarn frame.

[0009] In some embodiments, a limiting plate is installed at the back end of the yarn hanging rod, and the surface of the yarn hanging rod is coated with an antistatic coating.

[0010] In some embodiments, a movable component is also included, which is installed at the bottom of the yarn frame, and the yarn frame is actively or passively displaced by the movable component.

[0011] In some embodiments, the movable component includes a sliding wheel and a track. The sliding wheel is rotatably mounted at the bottom of the yarn frame. The sliding wheel is displaced along the track laying direction, and the yarn frame is passively displaced by the movable component.

[0012] In some embodiments, the moving component includes a drive motor, a wheel frame, a sliding wheel, and a track. The drive motor is mounted on the side of the wheel frame, and the output end of the drive motor is connected to the sliding wheel. The sliding wheel is displaced along the track laying direction, and the yarn frame is actively displaced by the moving component.

[0013] A warp-knitted Jacquard intelligent yarn frame control system includes a main control module, a yarn rod control module, and a tension control module. The main control module is electrically connected to the yarn rod control module and the tension control module, respectively. The tension control module is electrically connected to the yarn rod control module.

[0014] The tension control module monitors data changes within the yarn hanging rod via sensors. The sensors measure the data and feed it back to the main control module. The main control module analyzes and compares the measured data with its stored initial data and sends control commands to the yarn hanging rod control module.

[0015] In some implementations, when the measured data is less than the initial data, the main control module issues a command to reduce the rotation speed to the yarn rod control module;

[0016] When the measured data is greater than the initial data, the main control module sends a command to increase the rotation speed to the yarn rod control module.

[0017] In some embodiments, the sensor is an air pressure sensor.

[0018] In some embodiments, a motion control module is also included, and the main control module is electrically connected to the motion control module;

[0019] After receiving instructions from an external controller or the user interface on the warp-knitting Jacquard smart yarn rig, the main control module activates the motion control module, which executes instructions to move the warp-knitting smart yarn rig from the initial position to the yarn-changing position.

[0020] By adopting the above technical solution, the beneficial effects of this utility model are:

[0021] 1. The warp-knitted Jacquard intelligent yarn frame of this utility model uses a tension control device in conjunction with a yarn rod drive device. The air pressure sensor in the tension control device detects data in a timely manner and feeds the data back to the yarn rod drive device to adjust the speed. This facilitates timely replenishment and release of excess tension, ensuring stability during the weaving process. The yarn rod drive device can also drive the yarn hanging rod and the yarn bobbin on the yarn hanging rod to rotate actively, thereby realizing active yarn supply, effectively regulating and improving the stability of yarn tension, and reducing adverse human intervention.

[0022] 2. Compared with the traditional fixed yarn structure, the warp-knitted Jacquard intelligent yarn frame structure in this utility model is more streamlined. By setting a moving component, the yarn frame can be moved actively or passively. After moving, the side operation space can be increased, which facilitates yarn changing operations.

[0023] 3. The warp-knitted Jacquard intelligent yarn frame in this utility model optimizes the setting of the yarn collecting plate. The yarn on the yarn bobbin is directly guided through the ceramic yarn guide eye on the yarn collecting plate and then pulled straight to the loom, reducing yarn deviation, making the yarn delivery more uniform, and avoiding the problem of uneven tension caused by bending.

Detailed Implementation

[0040] like Figures 1-13As shown, this utility model provides a warp-knitted Jacquard intelligent yarn frame, including a yarn frame frame 1, yarn hanging rods 4, yarn rod driving device 5, and tension control device 6. Several yarn hanging rods 4 are arranged on the yarn frame frame 1. Each yarn hanging rod 4 is independently controlled to rotate by the yarn rod driving device 5. Each yarn hanging rod 4 is equipped with a tension control device 6. Each tension control device 6 installed in the yarn hanging rod 4 is electrically connected to the corresponding yarn rod driving device 5 of the yarn hanging rod 4, and independently controls the rotation speed of each yarn hanging rod 4.

[0041] According to some embodiments of the present invention, optionally, the tension control device 6 includes at least one stress snap ring 61 that penetrates the surface of the yarn hanging rod 4, and a piston plate 60, an air pressure sensor 62, and a control component 601 disposed inside the yarn hanging rod 4.

[0042] According to some embodiments of the present invention, optionally, one end of the stress snap ring 61 is fixedly connected to the surface of the yarn hanging rod 4, and the other end is a movable end 611 connected to the piston plate 60 inside the yarn hanging rod 4; an air pressure sensor 62 is also provided in the sealed space 40 inside the yarn hanging rod 4 isolated by the piston plate 60, and the air pressure sensor 62 is electrically connected to the control component 601 connected to the piston plate 60 and the yarn frame drive device.

[0043] Multiple stress spring clips 61 are provided, such as two stress spring clips 61, distributed on two sides of the same position on the yarn hanging rod 4. The piston plate 60 is connected to the movable end 611 of the stress spring clips 61 on the upper and lower sides through the connector 602. Multiple stress spring clips 61 can ensure that the yarn bobbin 10 will not easily come loose after being installed on the yarn hanging rod 4, and at the same time facilitate the replacement of the yarn bobbin 10 on the yarn hanging rod 4. The yarn rod drive device 5 is usually an electric motor, and the control component 601 is usually a pneumatic rod. Hall sensor 63 can also be installed inside the yarn hanging rod 4 as needed. The Hall sensor 63 is used to detect the speed of rotation of the yarn hanging rod 4.

[0044] According to some embodiments of the present invention, optionally, it also includes a plurality of yarn collecting plates 3 installed on the yarn frame 1.

[0045] According to some embodiments of the present invention, optionally, a limiting plate 7 is installed at the back end of the yarn hanging rod 4, and the surface of the yarn hanging rod 4 is coated with an antistatic coating 41.

[0046] The function of the limiting plate 7 is to support the back side of the yarn bobbin 10. The thickness of the limiting plate 7 is selected according to the requirements. The surface of the yarn hanging rod 4 is coated with an antistatic coating 41. The antistatic coating 41 can effectively reduce the accumulation of static electricity generated by the friction between the yarn and the yarn hanging rod 4, and avoid problems such as yarn fuzz, tangling or breakage caused by static adsorption.

[0047] According to some embodiments of the present invention, optionally, a movable component 2 is also included, which is installed at the bottom of the yarn frame 1, and the yarn frame 1 is actively or passively displaced by the movable component 2.

[0048] According to some embodiments of the present invention, optionally, the moving component 2 includes a sliding wheel 21 and a track 22. The sliding wheel 21 is rotatably installed at the bottom end of the yarn frame 1. The sliding wheel 21 is displaced along the laying direction of the track 22, and the yarn frame 1 is passively displaced by the moving component 2.

[0049] According to some embodiments of the present invention, optionally, the moving component 2 includes a drive motor 23, a wheel frame 24, a sliding wheel 21, and a track 22. The drive motor 23 is installed on the side of the wheel frame 24, and the output end of the drive motor 23 is connected to the sliding wheel 21. The sliding wheel 21 moves along the laying direction of the track 22, and the yarn frame 1 moves actively through the moving component 2.

[0050] The warp-knitted Jacquard intelligent yarn frame structure of this utility model is more streamlined than that of traditional yarn frames, allowing the moving component 2 to move the yarn frame 1 out of its initial position. There are no complex structural obstructions on the yarn hanging surface at the side of the yarn frame 1, such as the tension rods present in traditional yarn frames. Based on the yarn frame structure of this utility model, the yarn hanging operation is more convenient. At the same time, due to the more streamlined structure, the maintenance cost is also lower.

[0051] With the development of robotics technology, yarn hanging operations can be replaced by yarn hanging robots 8. Compared to manual yarn hanging, the yarn hanging robot 8's actions are more precise and skillful, avoiding potential damage to the yarn during the hanging process and ensuring yarn quality. Common yarn hanging robots 8 can use a vision recognition device 82 to scan and identify the yarn hanging rod 4, then control the yarn hanging robotic arm 81 to operate the yarn hanging mechanism. Figure 10 .

[0052] This utility model also provides a warp-knitted Jacquard intelligent yarn frame control system, including a main control module 100, a yarn rod control module 200, and a tension control module 300. The main control module 100 is electrically connected to the yarn rod control module 200 and the tension control module 300, respectively, and the tension control module 300 is electrically connected to the yarn rod control module 200.

[0053] The tension control module 300 monitors the data changes within the yarn hanging rod 4 through sensors. The sensors measure the data and feed it back to the main control module 100. The main control module 100 analyzes and compares the measured data with the initial data it stores. The main control module 100 then sends control commands to the yarn rod control module 200.

[0054] According to some embodiments of the present invention, optionally, when the measured data is less than the initial data, the main control module 100 issues a command to reduce the rotation speed to the yarn rod control module 200.

[0055] When the measured data is greater than the initial data, the main control module 100 sends a command to increase the rotation speed to the yarn rod control module 200.

[0056] According to some embodiments of the present invention, the sensor may optionally be an air pressure sensor 62.

[0057] According to some embodiments of the present invention, optionally, a motion control module 400 is also included, and the main control module 100 is electrically connected to the motion control module 400.

[0058] After receiving instructions from an external controller or the user interface on the warp-knitting Jacquard smart yarn rig, the main control module 100 starts the motion control module 400, which executes the instruction to control the warp-knitting smart yarn rig to move from the initial position to the yarn changing position.

[0059] Example 1

[0060] like Figures 1-8 As shown, this embodiment provides a warp-knitted Jacquard intelligent yarn frame, including a yarn frame frame 1, yarn hanging rods 4, yarn rod driving devices 5, tension control devices 6, and yarn collecting plates 3. Several yarn hanging rods 4 are arranged on the yarn frame frame 1. Each yarn hanging rod 4 is independently controlled to rotate by the yarn rod driving device 5. A tension control device 6 is installed inside each yarn hanging rod 4. Each tension control device 6 installed in the yarn hanging rod 4 is electrically connected to the yarn rod driving device 5 that independently controls the corresponding yarn hanging rod 4. The tension control device 6 and the yarn rod driving device 5 work together to independently control the rotational speed of each yarn hanging rod 4. The yarn frame frame 1 consists of a transverse frame 11 and a longitudinal frame 12, which can be assembled together by welding or screw fastening.

[0061] The tension control device 6 includes at least one stress spring 61 that runs through the surface of the yarn hanging rod 4, and a piston plate 60, an air pressure sensor 62, and a control component 601 disposed inside the yarn hanging rod 4. One end of the stress spring 61 is fixedly connected to the surface of the yarn hanging rod 4, and the other end is a movable end 611 connected to the piston plate 60 inside the yarn hanging rod 4. An air pressure sensor 62 is also disposed in the sealed space 40 inside the yarn hanging rod 4 isolated by the piston plate 60. The air pressure sensor 62 is electrically connected to the control component 601 connected to the piston plate 60 and the yarn frame drive device. A limiting plate 7 is installed at the back end of the yarn hanging rod 4, and the surface of the yarn hanging rod 4 is coated with an antistatic coating 41.

[0062] In this embodiment, when the warp-knitted Jacquard intelligent yarn frame is applied, the yarn bobbin 10 is installed on the yarn hanging rod 4. The yarn bobbin 10 is secured and limited by the stress spring 61 on the yarn hanging rod 4. The yarn on the yarn bobbin 10 is first guided to the ceramic yarn guide eye 31 on the yarn collecting plate 3 for guidance, and then guided to the loom. The yarn on the yarn bobbin 10 is directly guided through the ceramic yarn guide eye 31 on the yarn collecting plate 3, and the path of the yarn being guided to the loom becomes straight, reducing deviation and making the yarn delivery more uniform. It also avoids the problem of uneven tension caused by bending. When the loom pulls the yarn during knitting, the yarn bobbin 10 will be displaced. The stress spring 61 set on the surface of the yarn hanging rod 4 is subjected to the pressure applied by the yarn bobbin 10, which causes the data of the air pressure sensor 62 to change. This feedback changes the rotation speed of the yarn rod drive device 5 to adjust the tension of the yarn.

[0063] When the stress spring 61 secures the yarn bobbin 10, it forms an arched shape. The shape of the stress spring 61 is adjusted by controlling the displacement of the piston plate 60 through the control component 601. The piston plate 60 directly or indirectly controls the displacement of the movable end 611 of the corresponding stress spring 61. The closer the movable end 611 of the stress spring 61 is to the fixed end 612, the more pronounced the arching and bending of the stress spring 61. Since the movable end 611 of the stress spring 61 is movable, a sliding opening that matches it is usually provided on the surface of the yarn hanging rod 4, and a sealing plate is provided on the movable end 611 of the stress spring 61 that extends into the yarn hanging rod 4. The area of ​​the sealing plate is larger than the opening of the sliding opening, thereby improving the sealing effect of the sliding opening.

[0064] Example 2

[0065] like Figure 1 As shown, this embodiment provides a warp-knitted Jacquard smart yarn frame. The difference between this embodiment and embodiment 1 is that the warp-knitted Jacquard smart yarn frame in this embodiment also includes a moving component 2 installed at the bottom of the yarn frame 1. The yarn frame 1 is passively displaced by the moving component 2, which can be understood as moving the yarn frame by manually pulling in conjunction with the sliding wheel 21.

[0066] Specifically, the moving component 2 includes a sliding wheel 21 and a track 22. The sliding wheel 21 is rotatably installed at the bottom of the yarn frame 1. The sliding wheel 21 moves along the laying direction of the track 22, and the yarn frame 1 is passively moved by the moving component 2.

[0067] Example 3

[0068] like Figure 9 As shown, this embodiment provides a warp-knitted Jacquard smart yarn frame. The difference between this embodiment and embodiment 2 is that in this embodiment, the yarn frame 1 is actively displaced by the moving component 2, which can be understood as the yarn frame being moved by the sliding wheel 21 controlled by the motor.

[0069] Specifically, the moving component 2 includes a drive motor 23, a wheel frame 24, a sliding wheel 21, and a track 22. The drive motor 23 is installed on the side of the wheel frame 24, and the output end of the drive motor 23 is connected to the sliding wheel 21. The sliding wheel 21 moves along the laying direction of the track 22, and the yarn frame 1 moves actively through the moving component 2.

[0070] The two ends of the track 22 are the yarn rack usage position and the yarn changing position, respectively. The track 22 limits the movement distance. If the drive motor 23 drives the sliding wheel 21, it can be used in conjunction with a laser rangefinder sensor to detect the outward pulling distance of the yarn rack. When the maximum stroke is reached, the drive motor 23 is turned off.

[0071] In this embodiment, the bottom of the warp-knitted Jacquard intelligent yarn frame is driven by a drive motor 23. When in use, the drive motor 23 drives the sliding wheel 21 to rotate. The sliding wheel 21 at the bottom of the yarn frame 1 moves along the laying direction of the track 22, and the yarn cylinder 10 placed on the hanging rod 4 is replaced manually.

[0072] The warp-knitted Jacquard intelligent yarn racks in Examples 1-3 are not limited to a single layer and can be stacked in multiple layers; when two layers are selected, the upper yarn rack frame 1 is supported by frame 9. The yarn hanging operation is not limited to manual hanging; a yarn hanging robot 8 can also be used. The yarn hanging robot 8 is equipped with at least one yarn hanging robotic arm 81, which identifies the yarn to be hung via a visual recognition device 82. To adapt to multi-layer yarn hanging operations, the yarn hanging robot 8 can hang yarn by extending the yarn hanging robotic arm 81, requiring only a hollow structure 91 to be created on the second-layer frame 9 for cooperation. Figure 11 As shown.

[0073] Example 4

[0074] like Figure 12 As shown, this embodiment provides a warp-knitted Jacquard intelligent yarn frame control system, including a main control module 100, a yarn rod control module 200, and a tension control module 300. The main control module 100 is electrically connected to the yarn rod control module 200 and the tension control module 300, respectively, and the tension control module 300 is electrically connected to the yarn rod control module 200.

[0075] The tension control module 300 monitors the data changes inside the yarn hanging rod 4 through the air pressure sensor 62. The air pressure sensor 62 measures the measurement data and feeds the measurement data back to the main control module 100. The main control module 100 analyzes and compares the measurement data with the initial data stored in its storage.

[0076] When the measured data is less than the initial data, the main control module 100 sends a command to reduce the rotation speed to the yarn rod control module 200.

[0077] When the measured data is greater than the initial data, the main control module 100 sends a command to increase the rotation speed to the yarn rod control module 200.

[0078] When the warp-knitted Jacquard intelligent yarn creel is used in conjunction with a loom for weaving, if the yarn feeding speed of the yarn creel cannot keep up with the weaving speed of the loom, the loom pulls the yarn during weaving, causing the yarn bobbin 10 to shift. The stress spring 61 set on the surface of the yarn hanging rod 4 is subjected to the pressure applied by the yarn bobbin 10, causing the data monitored by the air pressure sensor 62 inside the yarn hanging rod 4 to change, that is, to differ from the initial data. The main control module 100 analyzes and processes the data and finally feeds it back to the yarn rod control module 200. The yarn rod control module 200 executes the command to reduce or increase the speed after receiving it.

[0079] Example 5

[0080] like Figure 13 As shown, this embodiment provides a warp-knitted Jacquard intelligent yarn frame control system. The warp-knitted Jacquard intelligent yarn frame control system in this embodiment also includes a mobile control module 400, and the main control module 100 is electrically connected to the mobile control module 400.

[0081] After receiving instructions from an external controller or the user interface on the warp-knitting Jacquard smart yarn rig, the main control module 100 starts the motion control module 400, which executes the instruction to control the warp-knitting smart yarn rig to move from the initial position to the yarn changing position.

[0082] In practical applications, the warp-knitted Jacquard intelligent yarn frame control system in this embodiment is mostly adapted to the warp-knitted Jacquard intelligent yarn frame in embodiment 3. That is, a moving component 2 is set at the bottom of the yarn frame 1. The moving component 2 includes a drive motor 23. After the moving control module 400 is started, the drive motor 23 drives the sliding wheel 21 to move along the laying direction of the track 22, that is, the yarn frame moves and adjusts as a whole.

[0083] Example 6

[0084] This embodiment provides a warp-knitted Jacquard intelligent yarn frame control system. Based on embodiment 4, to improve the application effect of the control system to the warp-knitted Jacquard intelligent yarn frame, the main control module 100 detects whether the yarn rod drive device 5 is turned on. When the yarn rod drive device 5 is turned on, the control component 601 is in a locked state and does not control the displacement of the piston plate 60. At this time, the control component 601 will not change the position of the piston plate 60, will not change the distance between the movable end 611 and the fixed end 612 of the stress retaining spring 61, and will not change the arch of the stress retaining spring 61. When the yarn rod drive device 5 is turned off, the control component 601 is unlocked. The control system changes the position of the piston plate 60 through the control component 601, indirectly changing the distance between the movable end 611 and the fixed end 612 of the stress retaining spring 61, adjusting the arch of the stress retaining spring 61, so that the yarn cylinder 10 is moved out or inserted into the yarn hanging rod 4.

[0085] In this embodiment, once the control system detects that the yarn rod drive device 5 is in the open state, the stress retainer 61 cannot be adjusted. That is, when the yarn rod drive device 5 controls the yarn bobbin 10 on the yarn hanging rod 4 to feed yarn, it cannot remove the already installed yarn bobbin 10 by adjusting the stress retainer 61.

[0086] Example 7

[0087] This embodiment provides a warp-knitted Jacquard intelligent yarn frame control system. Based on embodiment 5, the main control module 100 detects whether the yarn rod drive device 5 is turned on. When the yarn rod drive device 5 is turned off, the drive motor 23 is unlocked, and the control system starts the drive motor 23 in conjunction with it. The moving component 2 at the bottom of the target yarn frame is driven by the drive motor 23 to pull the entire target yarn frame outward to the preset yarn changing position.

[0088] In this embodiment, once the control system detects that the yarn rod drive device 5 is in the open state, it cannot control the target yarn frame displacement through the drive motor 23 to change the yarn; otherwise, the drive motor 23 first controls the target yarn frame to move outward, which facilitates the subsequent replacement of the yarn bobbin 10.

[0089] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
