Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, and in particular to a spool unwinding device and a warp knitting machine for preventing yarn from detaching from the yarn groove. Background Technology

[0002] Warp knitting is a technique that uses one or more sets of parallel yarns to simultaneously form loops on all the working needles of a machine in the warp direction to create a knitted fabric. The resulting fabric is called a warp-knitted fabric. The machine that performs this type of warp knitting is called a warp knitting machine.

[0003] When the warp knitting machine is in the knitting operation, the yarn often comes off from the yarn separating groove. The detached yarn will rub against the surrounding parts. Under the action of continuous and unstable friction, the yarn is very easy to break. This not only seriously affects the normal production efficiency of the warp knitting machine, but also leads to inconsistent product quality, increases the defect rate, and increases production costs. Utility Model Content

[0004] This utility model discloses a spool unwinding device and a warp knitting machine to prevent the yarn from detaching from the yarn groove. It aims to solve the technical problem that when the warp knitting machine is knitting, the yarn often detaches from the yarn groove and is easily broken after rubbing against the surrounding parts. This not only affects production efficiency, but also causes inconsistent product quality and increases the defect rate and cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spool unwinding device for preventing wire from detaching from the wire groove includes a mounting frame. Multiple anti-detachment components are arranged above the mounting frame. Each anti-detachment component includes a wire separating groove with multiple slots. Multiple connecting frames are fixedly connected to the front end of the wire separating groove. Each connecting frame is located on one side of a slot. A telescopic rod is fixedly connected to one side of each connecting frame. A buffer spring is fixedly connected to one side of each connecting frame, and the buffer springs are located outside the telescopic rods. Symmetrical fixing frames are arranged on the side of the buffer springs away from the connecting frames. The side of each fixing frame closest to the connecting frame is fixedly connected to the buffer spring and the front end of the telescopic rod. A fixing rod is fixedly connected to the inner side of each fixing frame, and a roller is movably connected to the outer side of each fixing rod. A movable frame is fixedly connected to the side of each fixing frame away from the connecting frames, and a telescopic electric rod is fixedly connected to the bottom end of the movable frame.

[0007] Equipped with a mounting frame and anti-detachment components, when the warp knitting machine is working, the threads drawn from the rotating drum are first stripped, and then multiple thread ends enter multiple slots opened on the separating groove. At this time, the telescopic electric rod installed at the bottom of the movable frame extends, driving the movable frame, which is fixedly connected to it, to move forward. Since the movable frame is connected to the fixed frame, and the fixed frame is connected to the connecting frame through a buffer spring and a telescopic rod, the fixed frame moves forward as the movable frame moves forward. During this process, the buffer spring is compressed to a certain extent, playing a role in buffering and fine adjustment. At the same time, the telescopic rod also extends and retracts accordingly, assisting the fixed frame to move smoothly. When the fixed frame moves forward to a certain position, the roller movably connected to the inner fixed rod of the fixed frame will contact the outer side of the thread that has entered the slot. Because the roller is movably connected to the fixed rod, when the thread moves under the action of the warp knitting machine, the roller can rotate accordingly, reducing the friction between the thread and the roller, thus ensuring the smooth movement of the thread. During the process, the thread end is initially positioned through the slots on the dividing groove, and then the roller contacts the outer side of the thread, forming a double anti-detachment structure. This can accurately restrict the thread to a specific position, preventing it from falling off the rotating drum or dividing groove due to shaking, tension changes, etc. when the warp knitting machine moves at high speed, ensuring that the thread is always on the normal working path. At the same time, the roller contacts the thread and can rotate with the thread, which can convert the sliding friction between the thread and the fixed frame and other components into rolling friction, greatly reducing friction, reducing wear between the thread and the equipment, and extending the service life of the thread and the equipment.

[0008] In a preferred embodiment, the top of the mounting frame is fixedly connected to multiple placement plates, and the bottom of the telescopic electric rod is fixedly connected to one side of the placement plates. Each of the multiple placement plates is fixedly connected to an automatic rod on the side near the telescopic electric rod. The automatic rods are all located behind the anti-detachment component, and the front end of each automatic rod is fixedly connected to an anti-sway plug. A rotating cylinder is movably connected to the outer side of each automatic rod.

[0009] In a preferred embodiment, the front end of the mounting frame is provided with a combing assembly, which includes a drive motor. The power output shaft of the drive motor is connected to a drive gear via a coupling. A linkage gear is movably connected to the outer side of the drive gear. The drive gear and the linkage gear are meshed through tooth grooves. The front end of the linkage gear is bolted to a rotating rod. The front end of the rotating rod is fixedly connected to a rotating rod. The front end of the rotating rod is fixedly connected to a sliding frame. A movable rod is movably connected inside the sliding frame. A fixing member is movably connected to the bottom end of the movable rod. A combing frame is fixedly connected to the top end of the movable rod. Multiple combing rods are fixedly connected to the top end of the combing frame. A linkage rod is fixedly connected to the side of the combing frame away from the movable rod. A connecting member is movably connected to the bottom end of the linkage rod.

[0010] With the combing component in place, when the warp knitting machine starts working and the yarn is ready to be woven, the drive motor starts and drives the drive gear to rotate. The rotation of the drive gear drives the linkage gear to rotate synchronously. The rotation of the linkage gear is transmitted to the rotating rod connected to it through bolts, so that the rotating rod starts to rotate. The rotation of the rotating rod drives the rotating rod fixed at the front end to perform a circular motion, causing the sliding frame connected to it to generate a movement trajectory. Inside the sliding frame, the movable rod can move within its limited space. As the sliding frame moves, the movable rod slides and swings accordingly inside. The bottom end of the movable rod maintains a relatively stable position through a movable connection fastener. At the same time, the combing frame fixed at the front end of the top of the combing frame moves with the movement of the movable rod. Multiple combing rods fixed at the top of the combing frame come into contact with the yarn during the movement. When the yarn tends to entangle, the combing rod combs and guides the yarn. Simultaneously, the linkage rod fixedly connected to one side of the combing frame also moves with the movement of the combing frame. The bottom end of the linkage rod, through a movable connection fastener, plays an auxiliary linkage and adjustment role throughout the entire movement process, ensuring that the movement of the combing frame and combing rods is more stable and accurate, thereby effectively preventing the yarn from entangled during the weaving process and ensuring the smooth progress of the weaving work.

[0011] A warp knitting machine includes a spool unwinding device for preventing yarn from detaching from the yarn groove as described above, and also includes a warp knitting machine body. Multiple warp rollers are fixedly connected inside the warp knitting machine body. Both sides of the mounting frame are fixedly connected to both sides of the inside of the warp knitting machine body. A slot is opened on one side of the inside of the warp knitting machine body. The inside of the slot is movably connected to the drive gear and the linkage gear. The side of the fixing member away from the movable rod is fixedly connected to the inner wall of the warp knitting machine body. The front side of the connecting member is fixedly connected to the inner wall of the warp knitting machine body. The combing assembly is located between the warp rollers and the anti-detachment assembly.

[0012] As can be seen from the above, the yarn unwinding device and warp knitting machine provided by this utility model have the following technical effects: the double anti-loosening structure accurately fixes the yarn, preventing the yarn from falling off the rotating drum or the dividing groove due to shaking and tension changes when the warp knitting machine is running at high speed, ensuring that it is on the normal working path, the drum can rotate with the yarn, changing sliding friction into rolling friction, reducing friction, reducing wear on the yarn and equipment, and extending the service life of both.

The combing assembly 9 includes a drive motor 901, and the power output shaft of the drive motor 901 is connected to a drive gear 902 via a coupling.

A rotating rod 904 is bolted to the front end of the linkage gear 903, and a rotating rod 905 is bolted to the front end of the rotating rod 904.

The bottom front end of the linkage rod 911 is rotatably connected to a connector 912.

[0024] Reference Figure 1 and Figure 2 A warp knitting machine includes a spool unwinding device for preventing yarn from detaching from the yarn groove as described above, and also includes a warp knitting machine body 1. Multiple warp rollers 2 are bolted to the inside of the warp knitting machine body 1. Both sides of the mounting frame 3 are bolted to both sides of the inside of the warp knitting machine body 1. A slot is provided on one side of the inside of the warp knitting machine body 1. The inside of the slot is rotatably connected to the drive gear 902 and the linkage gear 903. The side of the fixing member 906 away from the movable rod 907 is bolted to the inner wall of the warp knitting machine body 1. The front side of the connecting member 912 is bolted to the inner wall of the warp knitting machine body 1. The combing assembly 9 is located between the warp rollers 2 and the anti-detachment assembly 8.

[0025] Working principle: When the warp knitting machine body 1 is working, the thread led out from the rotating drum 7 is first stripped, and then multiple thread ends enter multiple slots opened on the thread separating groove 801. At this time, the telescopic electric rod 809 installed at the bottom of the movable frame 808 extends, driving the movable frame 808, which is fixedly connected to it, to move forward. Since the movable frame 808 is connected to the fixed frame 803, and the fixed frame 803 is connected to the connecting frame 802 through the buffer spring 804 and the telescopic rod 805, the fixed frame 803 also moves forward as the movable frame 808 moves forward. During this process, the buffer spring 804 and the telescopic rod 805 act as the fixed frame 803 moves forward. Spring 804 is compressed to a certain extent, which plays a role in buffering and fine adjustment. At the same time, telescopic rod 805 will also extend and retract accordingly to assist the fixed frame 803 in moving smoothly. When the fixed frame 803 moves forward to a certain position, the roller 807 movably connected on the inner fixed rod 806 of the fixed frame 803 will come into contact with the outer side of the thread entering the slot. Because the roller 807 is movably connected to the fixed rod 806, when the thread moves under the action of the warp knitting machine body 1, the roller 807 can rotate accordingly, reducing the friction between the thread and the roller 807, thereby ensuring the smooth movement of the thread.

[0026] When the warp knitting machine body 1 starts working and the yarn is ready to be woven, the drive motor 901 starts and drives the drive gear 902 to rotate. The rotation of the drive gear 902 drives the linkage gear 903 to rotate synchronously. The rotation of the linkage gear 903 is transmitted to the rotating rod 904 connected to it through bolts, causing the rotating rod 904 to start rotating. The rotation of the rotating rod 904 then drives the rotating rod 905 fixed at the front end to make a circular motion, so that the sliding frame 908 connected to it generates a motion trajectory. Inside the sliding frame 908, the movable rod 907 can move within its limited space. As the sliding frame 908 moves, the movable rod 907 slides and swings accordingly inside it. The bottom end of the movable rod 907 is kept in a relatively stable position by the fixed part 906 that is movably connected. At the same time, the combing frame 909 fixed at the front end of its top moves with the movement of the movable rod 907. Multiple combing rods 910 fixed at the top of the combing frame 909 come into contact with the yarn during the movement. When the yarn tends to entangle, the combing rods 910 comb and guide the yarn.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions.
