Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a thread mending control device. Background Art

[0002] As composite nonwovens are widely used in various markets, reinforced nonwovens, as a key member of the composite nonwoven fabric family, are also gaining widespread application. Patent application number 201820886617.1, a pre-press roller-free web laying machine, and patent application number 202120914550.X, a feeding device for improving the tension stability of nonwoven reinforcement materials, are commonly used in nonwoven production. The web laying machine without pre-pressing roller has a frame-shaped frame, and a mesh curtain is laid on the upper surface of the frame. There are two rows of tow center lines above the web laying machine, which is also the position where the tows fall to the web laying machine. A first suction duct and a second suction duct are provided in the web laying machine frame and at the lower part of the two rows of tow center lines. The first suction duct and the second suction duct are connected to the fan. A first suction duct guide device and a second suction duct guide device are provided at the lower part of the mesh curtain and at the upper part corresponding to the first suction duct and the second suction duct. The first suction duct guide device and the second suction duct guide device are fixed on the web laying machine frame. An electrostatic eliminator is fixed on the upper part of the web laying machine frame and at the corresponding position of the second suction duct. A front guide walkway is provided in the direction of operation of the electrostatic eliminator and the fiber web, and a rear guide walkway is provided behind the two rows of tow center lines of the web laying machine. The front and rear guide walkways are both fixed to the web machine frame. The front guide bracket assembly is fixed to the front end of the web machine frame and bolted to the front support frame of the front guide assembly. One end of the front support frame is fixedly connected to one end of the web machine frame. The other end of the front support frame is equipped with a front guide roller. A front guide static eliminator is fixedly connected to the upper portion of the front support frame. Two guide rollers are fixed inside the front end of the web machine frame, with the two guide rollers positioned in corresponding upper and lower positions. The rear end of the web machine frame also has rear guide rollers fixed to the upper and lower portions. The tensioning device, active guide rollers, and error correction device are also fixed inside the rear end of the web machine frame. The web curtain of the web laying machine is wound around the active guide roller, the tensioning roller of the tensioning device, the rear guide roller, the front guide roller, the guide rollers, and the error correction device's error correction rollers. The active guide rollers drive the movement of the web curtain. The feeding device, which can improve the tension stability of nonwoven fabric reinforcement materials, mainly includes a main unit, a control unit, and an operating unit. The main unit and the control unit are electrically connected by wires, and the control unit and the operating unit are connected by a network cable. The main machine consists of an upper feeder and a lower feeder. The upper feeder's frame is equipped with, from top to bottom, a deckle reed A, a passive light roller, a deckle reed B, and a rubber roller. The lower feeder's frame is equipped with, from top to bottom, a deckle reed C, a passive light roller, a deckle reed D, a rubber roller, and an active light roller. Because reinforced nonwovens are mostly made of glass fiber, problems such as yarn breakage, blockage, and entanglement often occur during the use of these devices.

[0003] To address this technical issue, when fiber anomalies occur, workers typically remove the defective glass fibers and reintroduce new ones into the reinforcement device. This process takes anywhere from tens of seconds to over ten minutes, leaving the broken fibers without reinforcement material, seriously impacting product quality. Patent application number 2013100551508, filed under patent number 2013100551508, addresses this problem by applying the patented technology to nonwoven fabrics. However, its shortcomings include: first, inability to accurately patch the fibers, which in turn affects the quality of reinforced nonwovens; second, the patented system uses spring deformation to compensate for tension, preventing breakage caused by excessive tension on the fibers; however, the spring is a consumable part and requires frequent replacement; third, the speed of the payoff motor is controlled by feedback from a tension sensor. The tension sensor feedback signal is analog and susceptible to interference, leading to lag and inaccurate control in the electronic control system; fourth, if a break occurs in the doubling machine, this system simply patchs the broken fibers without providing control over the specific location of the broken fibers.

[0044] The utility model is in use:

[0045] 1. Before system initialization, the feeding rack 31 moves to the origin A photoelectric switch, which is the origin position, and the slider 18 at the output end of the servo electric cylinder MⅠ returns to the origin B photoelectric switch position.

[0046] 2. Broken Fiber: Several glass fibers pass through the existing feeding device. One of the fiber bundles breaks. The broken fiber and the remaining glass fibers pass through the corresponding photoelectric yarn detector I8 and electric wire cutter I9, respectively, and continue to move forward. When the broken end of the broken glass fiber passes the corresponding photoelectric yarn detector I8, the photoelectric yarn detector I8 detects the broken endpoint. The coil KⅠA of the intermediate relay I corresponding to the photoelectric yarn detector I8 is energized and an alarm is issued. At this time, the broken glass fiber continues to move forward. At the same time, the PLC programmable controller receives the broken fiber signal, and the normally open contact KⅠ of the intermediate relay I corresponding to the photoelectric yarn detector I8 closes. The electric wire cutter I9 corresponding to the normally open contact KⅠ of the intermediate relay I cuts it after receiving the signal and feeds back a signal to the PLC. This signal is the starting signal for the feeding servo motor MⅡ30 to drive the active rubber roller 28 to rotate for the repair of the fiber. At this time, the glass fiber head of the repaired fiber cake is end B in the figure, and the cut glass fiber end point is the new glass fiber starting end A. And the new glass fiber after being cut continues to run with the mesh curtain (because there is a distance between the lower feeder and the wire filling device), so AB automatically fits together, and the other end point of the cut glass fiber is the new glass fiber initial end D. This section of glass fiber is in a stopped state, waiting for manual processing.

[0047] 3. Thread Filling: One end of the glass fiber from bobbin 11 passes sequentially through positioning tube A14, the space between the locking disk and the locking block, and positioning tube B20. The fiber then moves in an S-shaped pattern over floating optical roller 21, passive optical roller 22, and positioning tube C23 before continuing downward. The fiber is fed into servo motor MⅡ30, which rotates active rubber roller 28. The fiber then moves in an S-shaped pattern over active and passive rubber rollers 28 and 29. One end of the fiber continues downward, passing photoelectric yarn feeler Ⅱ33 and electric wire cutter Ⅱ34. The output end of cylinder B19 pushes the locking disk 16, pressing the fiber between it and the locking block 15 to prevent the bobbin fiber from being pulled. Cylinder A32 drives the passive rubber roller connecting frame 42 toward the active rubber roller 28, where it is pressed against the active rubber roller 28 by the passive rubber roller 29. After the D-end glass fiber is manually processed, it is put into the electric wire breaker II 34. When it receives the PLC programmable controller signal, the K2A coil is energized and the normally open contact K2 is closed. The electric wire breaker II 34 receives the PLC programmable controller signal and cuts the glass fiber extending to its lower part. At this time, the repairing glass fiber head is the C-end, and the system automatically fits the C-end and the D-end.
