Description

Technical Field

[0001] This utility model relates to the field of weft feeder technology, and in particular to a vertical weft feeder for metal wire mesh. Background Technology

[0002] In the weaving process of metal wire mesh, the weft feeder is used to control the weft tension. Therefore, the wire is fed through the feeder by the pay-off spool before entering the weaving machine for weaving. However, in actual use, when the rotational speed of the weft feeder changes, the tension may change instantaneously due to mechanical transmission gaps (such as mechanical response delays). The wire may become loose, pile up, or break due to inertia or sudden tension changes, thus requiring dynamic compensation. Based on this, this invention proposes a vertical weft feeder for metal wire mesh, which dynamically adjusts the tension through guide wheels to achieve dynamic compensation. Utility Model Content

[0003] The purpose of this invention is to provide a vertical weft feeder for metal wire mesh, thereby solving the problems mentioned above.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a vertical weft feeder for metal wire mesh, comprising a pay-off spool, the axial end of which is mounted on a base via symmetrically distributed support frames. A vertical plate is connected to one side of the base via a connecting seat. A tensioning mechanism is provided at the end of the base near the connecting seat. A vertical frame is provided at the end of the vertical plate near the connecting seat, and several guide wheel sets are mounted on the frame, with tension sensors positioned between the guide wheel sets. A lubrication box is provided on the vertical plate, and a turntable is rotatably mounted on the top of the vertical plate. Extension rods are symmetrically arranged above and below the turntable. A photoelectric sensor is positioned at the center of the upper extension rod, and a light-transmitting hole is provided on the turntable to cooperate with the photoelectric sensor. A front bracket is provided perpendicularly to the end of the lower extension rod, and a guide hole is provided on the upper part of the front bracket. The photoelectric sensor and the tension sensor are electrically connected to a control cabinet, which is electrically connected to a drive motor that drives the tensioning mechanism and a motor that drives the turntable to rotate.

[0006] Furthermore, the plurality of guide wheel groups include guide wheel one, guide wheel two, guide wheel three and guide wheel four arranged sequentially from bottom to top, the tension sensor is located between guide wheel one and guide wheel two, and guide wheel four is located above the lubrication box; guide wheel five is arranged inside the lubrication box, and the metal wire passes sequentially around guide wheel one, tension sensor, guide wheel two, guide wheel three, guide wheel four and guide wheel five.

[0007] Furthermore, the lubrication tank contains lubricating fluid.

[0008] Furthermore, the tensioning mechanism includes a partition located in the middle of the base. A slide rail is provided on the upper surface of the partition, and a slider is slidably mounted on the slide rail. The upper end of the slider is connected to a tensioning wheel through an inclined mounting plate. A rack is integrally formed on the side of the slider away from the mounting plate. The rack meshes with a sector gear one and a sector gear two. The sector gear one and sector gear two are respectively connected to gear one and gear two through rotating shafts, and gear one and gear two mesh with each other. The rotating shaft of gear one passes through the partition and is connected to a drive mechanism.

[0009] Furthermore, the drive mechanism includes a worm gear mechanism, which includes a worm wheel that is keyed to the rotating shaft, the worm wheel meshing with a worm, and the worm key connecting to the drive motor.

The rollers are located on the outer edge of the turntable, and a rubber ring is fitted on the outer edge of the turntable. The outer wall of the rubber ring abuts against the rollers.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model relates to a vertical weft feeder for metal wire mesh. A tension sensor detects tension changes in real time and transmits the signal to a control cabinet. The control cabinet then controls the tensioning mechanism to dynamically adjust the tension of the wire, achieving dynamic compensation to maintain a stable wire path and balanced tension.

[0022] like Figure 1-5As shown, a vertical weft feeder for metal wire mesh includes a pay-off spool 1. The shaft end of the pay-off spool 1 is mounted on a base 3 via symmetrically distributed support frames 2. One side of the base 3 is connected to a vertical plate 6 via a connecting seat 5. A tensioning mechanism 4 is installed at the end of the base 3 near the connecting seat 5. A vertical frame 7 is installed at the end of the vertical plate 6 near the connecting seat 5. Several guide wheel sets are installed on the vertical frame 7, and tension sensors 10 are installed between the guide wheel sets to detect the tension of the metal wire 22. A lubrication box 13 is installed on the vertical plate 6, and the lubrication box 13 contains lubricating fluid. In this embodiment, soap solution is used as the lubricating fluid. A turntable 17 is rotatably mounted on the top of the vertical plate 6 for winding the metal wire 22 from the pay-off spool 1 onto the turntable 17. Extending rods are symmetrically installed above and below the turntable 17. A photoelectric sensor 23 is installed at the center of the upper extending rod. The turntable 17 has a light-transmitting hole 24 that cooperates with the photoelectric sensor 23. The photoelectric sensor 23 is used to detect the number of metal wires 22 wound on the turntable 17 and transmits the signal to the control cabinet 26. A front bracket 20 is installed at the end of the lower extending rod, perpendicular to it. A guide hole 21 is opened on the upper part of the front bracket 20. The metal wires 22 pass through the guide hole 21, so that the weft yarn is perpendicular to the warp yarn. The photoelectric sensor 23 and the tension sensor 10 are electrically connected to the control cabinet 26. The control cabinet 26 is electrically connected to the drive motor that drives the tensioning mechanism 4 and the motor 25 that drives the turntable 17 to rotate.

[0023] The plurality of guide wheel assemblies include guide wheel 1 (9), guide wheel 2 (11), guide wheel 3 (12), and guide wheel 4 (14) installed sequentially from bottom to top. The tension sensor 10 is located between guide wheel 1 (9) and guide wheel 2 (11) and can accurately measure the tension. Guide wheel 4 (14) is located above the lubrication box 13. Guide wheel 5 (15) is installed inside the lubrication box 13. The metal wire 22 passes sequentially around guide wheel 1 (9), tension sensor 10, guide wheel 2 (11), guide wheel 3 (12), guide wheel 4 (14), and guide wheel 5 (15).

[0024] The tensioning mechanism 4 includes a partition 405 located in the middle of the base 3. A slide rail 404 is mounted on the upper surface of the partition 405, and a slider 403 is slidably mounted on the slide rail 404. The upper end of the slider 403 is connected to the tensioning wheel 401 through an inclined mounting plate 402. A rack 406 is integrally formed on the side of the slider 403 away from the mounting plate 402. The rack 406 meshes with a sector gear 1 407 and a sector gear 2 409. The sector gear 1 407 and the sector gear 2 409 are respectively connected to a gear 1 408 and a gear 2 410 through a rotating shaft. The gear 1 408 and the gear 2 410 mesh with each other. The rotating shaft located at the gear 408 passes through the partition 405 and is connected to the drive mechanism. The drive mechanism includes a worm gear mechanism 411, which includes a worm wheel that is keyed to the rotating shaft. The worm wheel meshes with a worm, and the worm key is connected to the drive motor (forward and reverse motor).

[0025] Specifically, when the tension sensor 10 detects a change in tension, the signal is transmitted to the control cabinet 26. The PID control algorithm module inside the control cabinet 26 (this is an existing technology and will not be elaborated further here) controls the drive motor to start according to the signal. Under the transmission of the worm gear mechanism 411, gear 1 408 rotates, and gear 2 410 meshing with it rotates in the opposite direction. When gear 1 408 and gear 2 410 rotate, the sector gear 1 407 and sector gear 2 409 on them rotate synchronously. The sector gear drives the rack 406 meshing with it to move back and forth along the slide rail 404, ultimately realizing the back and forth movement of the tension wheel 401. When the tension wheel 401 drives the metal wire 22 to move back and forth, the movement compensates for the path length and avoids sudden changes in tension. That is, it avoids the problem of uneven tension causing the winding position on the turntable 17 to shift, resulting in overlapping, crossing, or loosening, which in turn affects the subsequent weft straightening accuracy.

[0026] The upper and lower ends of the support frame 7 are respectively equipped with guide holes 16 and 8 for guiding the metal wire 22, which serve as guides.

[0027] Rollers 18 are installed on the opposite surfaces of the ends of the upper and lower extension rods. The rollers 18 are located on the outer edge of the turntable 17. A rubber ring 19 is fitted on the outer edge of the turntable 17. The outer wall of the rubber ring 19 abuts against the rollers 18. The metal wire 22 comes out from the gap between the rubber ring 19 and the turntable 17 and is sent to the weaving machine for weaving.

[0028] The operation process of this utility model is as follows:

[0029] First, after the wire 22 comes out of the pay-off drum 1, it passes sequentially through the tensioning mechanism 4, including the tensioning wheel 401, guide hole 8, guide wheel 9, tension sensor 10, guide wheel 11, guide wheel 12, guide wheel 14, guide wheel 15, guide hole 11, turntable 17, guide hole 21, and the braiding machine. Then, the photoelectric sensor 22 and the tension sensor 10 are activated, and the turntable 17 rotates under the action of the motor 25. During rotation, the wire 22 on the pay-off drum 1 winds around the turntable 17. When the photoelectric sensor 22 detects that the light-transmitting hole 24 is blocked by the wire 22, it transmits a signal to the control cabinet 26. The control cabinet 26 controls the motor 25 to slow down or shut down. Finally, the tension sensor 10 detects a sudden decrease in tension and transmits a signal to the control cabinet 26. The control cabinet 26 controls the tensioning mechanism 4 to drive the tensioning wheel 401 to move back and forth to compensate for the path length, avoiding the problem of overlapping, crossing, or loosening due to sudden changes in tension, which would affect the accuracy of subsequent weft straightening.
