Description

Technical Field

[0001] The invention relates to the technical field of weaving equipment detection, in particular to a weaving equipment detector utilizing an encoder to detect weft threads. Background Art

[0002] In the weaving process, the weaving density of the weft is one of the key factors affecting the quality of the fabric. The weaving equipment detector that detects the weft through an encoder can accurately record the number and position of the weft insertion. For example, when producing high-quality silk fabrics, the weft density is extremely high. The detector can ensure that the number of wefts per centimeter width meets strict quality standards, making the texture of the fabric uniform and delicate, and improving the quality and grade of the product.

[0003] In the process of using an encoder to detect the weft thread, it is necessary to install and connect the encoder to the main shaft of the weaving equipment. During the installation process, there will be problems such as eccentricity and tilt between the main shaft and the output end of the encoder, which will cause measurement errors of the encoder. For example, eccentric installation will cause periodic fluctuations in the frequency of the pulse signal measured by the encoder. Even if the spindle speed is stable, the calculated weft thread speed will produce errors, affecting the correct judgment of the weft thread state. For this reason, we propose a weaving equipment detector that uses an encoder to detect the weft thread. Summary of the invention

[0039] It should be noted here that: through the control component and the rotating component, each group of transmission plates 1001 after being subjected to force moves towards each other, and during the movement of each group of transmission plates 1001, through the connecting action of the elastic component, each group of support plates 1002 moves toward the outside of the first spline shaft 702 and resists each other, and through the resisting and squeezing action of each group of support plates 1002 and the outside of the first spline shaft 702, the first spline shaft 702, the spline sleeve 701, the second spline shaft 801 and the main shaft 102 after the connected transmission are centrally supported to ensure the coaxiality of the first spline shaft 702, the spline sleeve 701, the second spline shaft 801 and the main shaft 102 during the connected transmission process.

[0040] Preferably, the control component includes a driving ring 1201 rotatably connected to the inside of the circular cover 9, a plurality of groups of inclined grooves 1202 are provided on the driving ring 1201, each group of inclined grooves 1202 is slidably connected with a sliding pin 1203, each group of sliding pins 1203 is respectively fixed to each group of transmission plates 1001, and a rotating component for rotating the driving ring 1201 is provided on the circular cover 9; the rotating component includes a worm wheel 1401 fixed to one side of the driving ring 1201, the worm wheel 1401 is concentrically arranged with the driving ring 1201, a driving shaft 1402 is rotatably connected to the circular cover 9, a worm 1403 is fixed on the driving shaft 1402, the worm 1403 and the worm wheel 1401 are meshed with each other, and a driving pin 1404 for driving the driving shaft 1402 is fixed at one end of the driving shaft 1402;

[0041] It should be noted here that: the driving shaft 1402 is rotated by the driving pin 1404, and during the rotation of the driving shaft 1402, the worm 1403 is driven to rotate, and during the rotation of the worm 1403, the driving ring 1201 is forced to rotate through the mutual meshing transmission between the worm 1403 and the worm wheel 1401, and during the rotation of the driving ring 1201, the groups of transmission plates 1001 that are subjected to force move through the interaction between the groups of inclined grooves 1202 on the driving ring 1201 and the groups of sliding pins 1203, and during the movement of the groups of transmission plates 1001, the groups of transmission plates 1001 that are subjected to force move closer to each other through the sliding guiding effect of the groups of second sleeves 1301 and the second sliding rods 1302.

[0042] Preferably, the sliding assembly includes a plurality of second sleeves 1301 fixed on the inner wall of the circular cover 9, and a second slide bar 1302 is slidably connected to the second sleeve 1301, and one end of the second slide bar 1302 is fixed to the transmission plate 1001;

[0043] It should be noted here that the second sleeve 1301 and the second slide bar 1302 facilitate the sliding guidance of the transmission plate 1001 after being subjected to force.

[0044] Preferably, the elastic component includes a plurality of groups of third sleeves 1101 fixed on the transmission plate 1001, each group of the third sleeves 1101 is slidably connected with a third slide bar 1102, one end of the third slide bar 1102 is fixed to the support plate 1002, and the outer side of each group of the third sleeves 1101 is sleeved with a second spring 1103;

[0045] It should be noted here that: through the connection action of the elastic component, each group of support plates 1002 moves toward the outer side of the first spline shaft 702 and offsets each other. As the first spline shaft 702 offsets and limits the outer side of the support plate 1002 and continues to transmit the transmission plate 1001, the transmission plate 1001 is forced to move toward the support plate 1002 for contraction. During the movement, each group of third sliding rods 1102 is pushed to slide on each group of third sleeves 1101 respectively, and the second spring 1103 is deformed by force to generate elastic force. Through the elastic force of the second spring 1103, it is easy to push the support plate 1002 to offset and support the outer side of the first spline shaft 702 with greater force.

[0046] Preferably, the adjustment component includes a threaded rod 401 rotatably connected to the mounting plate 3, a threaded tube 402 is threadedly engaged with the threaded rod 401, one end of the threaded tube 402 is fixed to the outer side of the braiding device body 101, and a rotating pin 403 for rotating the threaded rod 401 is fixed to one end of the threaded rod 401; the guide component includes two groups of fourth sleeves 501 fixed to the mounting plate 3, the two groups of fourth sleeves 501 are symmetrically arranged on both sides of the threaded rod 401, a fourth sliding rod 502 is slidably connected to the fourth sleeve 501, and one end of the fourth sliding rod 502 is fixed to the outer side of the braiding device body 101;

[0047] It should be noted here that: the threaded rod 401 is driven to rotate by the rotating pin 403. During the rotation of the threaded rod 401, the mutual meshing transmission between the threaded rod 401 and the threaded tube 402 drives the mounting plate 3 to move under force. During the movement of the mounting plate 3, the sliding guiding effect of the two sets of fourth sleeves 501 and the fourth sliding rod 502 makes the mounting plate 3 under force move toward or away from the weaving device body 101, thereby adjusting the distance between the mounting plate 3 and the weaving device body 101.

[0048] Preferably, the winding assembly includes a support frame 601 fixed to one side of the mounting plate 3, a winding wheel 602 for winding the transmission line is fixed on the support frame 601, and a clamping groove 603 for clamping and limiting the transmission line after winding is provided on the winding wheel 602;

[0049] It should be noted here that: after the installation of the encoder body 2 is completed, the excess transmission line on the encoder body 2 is wound on the winding wheel 602 and the wound transmission line is limited by the slot 603, so that the encoder body 2 can effectively organize multiple groups of lines when in use to avoid mutual entanglement.

[0050] In this scheme: a weaving equipment detector using an encoder to detect weft threads comprises the following steps:

[0051] During the operation of the weaving equipment detector using the encoder to detect the weft, the weaving equipment body 101 is pre-placed on the mounting plate 3. During the placement process, the threaded rod 401 is driven to rotate by the rotating pin 403. During the rotation of the threaded rod 401, the mounting plate 3 is driven to move under force through the mutual meshing transmission between the threaded rod 401 and the threaded tube 402. During the movement of the mounting plate 3, the two sets of fourth sleeves 501 and the fourth sliding rod 502 are used to slide and guide the mounting plate 3 under force to move toward the weaving equipment body 101. During the movement, the first spline shaft 702 at the input end of the encoder body 2 is connected to the spline sleeve 701, so that transmission can be performed between the first spline shaft 702, the spline sleeve 701, the second spline shaft 801 and the main shaft 102;

[0052] After the input end of the encoder body 2 is connected to the main shaft 102 for transmission, the driving shaft 1402 is rotated through the driving pin 1404. During the rotation of the driving shaft 1402, the worm 1403 is driven to rotate. During the rotation of the worm 1403, the driving ring 1201 is forced to rotate through the mutual meshing transmission between the worm 1403 and the worm wheel 1401. During the rotation of the driving ring 1201, the interaction between each group of inclined grooves 1202 on the driving ring 1201 and each group of sliding pins 1203 respectively causes each group of transmission plates 1001 to move after being subjected to force. During the movement of each group of transmission plates 1001, each group of second sleeves 1301 and the second sliding rod 1302 are used to guide the sliding of each group of transmission plates 1001 after being subjected to force. 01 move towards each other, and during the movement of each group of transmission plates 1001, through the connection effect of the elastic component, each group of support plates 1002 moves toward the outside of the first spline shaft 702 and resists each other, and through the counter-extrusion effect of each group of support plates 1002 and the outside of the first spline shaft 702, the first spline shaft 702, the spline sleeve 701, the second spline shaft 801 and the main shaft 102 after the connection transmission are centrally supported to ensure the coaxiality of the first spline shaft 702, the spline sleeve 701, the second spline shaft 801 and the main shaft 102 during the connection transmission process, and avoid eccentricity, tilt and other problems that cause measurement errors of the encoder. After the input end of the encoder body 2 is centrally positioned and supported, the encoder body 2 and the mounting plate 3 are limitedly installed by means of threads;

[0053] After the encoder body 2 is installed, the excess transmission line on the encoder body 2 is wound on the winding wheel 602 and the wound transmission line is limited by the card slot 603, so that the encoder body 2 can effectively organize multiple groups of lines when in use to avoid mutual entanglement. After the encoder body 2 is installed, the encoder continuously outputs pulse signals as the main shaft 102 rotates. The microprocessor accurately counts the number of revolutions and angles of the main shaft 102, and converts the real-time weaving speed and position information of the weft. The microprocessor compares the current speed and tension of the weft with the preset normal range. Once a sudden change in speed is detected, the tension deviates from the threshold, or the photoelectric sensor indicates that the weft is missing, it is immediately determined to be an abnormal state, and the alarm mechanism is triggered immediately. The fault information is prominently displayed on the human-machine interface, and a stop or deceleration command is simultaneously sent to the weaving equipment to prevent the generation of defective products, thereby further achieving the purpose of weft detection of the weft of the weaving equipment.
