Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and more specifically to a wire guide frame capable of detecting broken wires. Background Technology

[0002] The yarn guide is an important component in textile machinery used to guide yarn and maintain stable tension. It can effectively reduce yarn wear and skipped yarn problems. Its rollers are usually made of wear-resistant materials such as ceramic, plastic or stainless steel, and are suitable for equipment such as winding machines and tensioners.

[0003] The following problems typically exist with existing conductor frames during the conductor laying process:

[0004] 1. The existing conductor frame lacks a wire breakage detection device during the conductor laying process, which causes the equipment to continue running even when a wire breaks;

[0005] 2. When the guide rollers of the existing guide frame are damaged, the machine needs to be stopped and replaced. In particular, when multiple guide rollers are damaged, the replacement efficiency is slow. Summary of the Invention

[0006] The present invention provides a wire frame capable of detecting broken wires in order to solve the above-mentioned technical problems. The wire frame has a broken wire detection function and the wire assembly is designed with two first guide rollers arranged symmetrically at the top and bottom.

[0007] To solve the above-mentioned technical problems, the present invention provides a technical solution for a conductor frame capable of detecting broken wires:

[0008] The device includes a frame with a rotating housing rotatably connected to it. Multiple sets of guide wires are mounted on the rotating housing. Vertical limiting grooves corresponding to the guide wire sets are provided on the rotating housing. Each guide wire set includes two first guide rollers symmetrically arranged vertically and slidably connected to the vertical limiting grooves. A first spring is placed between the two first guide rollers. An infrared transmitter and an infrared receiver are connected to the left and right sides of the upper interior of the frame, respectively. The infrared transmitter emits infrared rays to the infrared receiver. A limiting device for limiting the rotation housing is provided on the side of the frame. When no wire is being guided, the first spring pushes the two first guide rollers of the guide wire set to the two ends of the vertical limiting grooves, and the upper first guide roller blocks the infrared transmitter and receiver. When wire is being guided, the upper first guide roller guides the yarn, and the upper first guide roller is pressed down by the preload of the yarn and moves away from the infrared transmitter and receiver.

[0009] Both sides of the frame are threaded with external connecting columns; the inner end of each external connecting column is connected to a rotating shaft, and the outer end of each external connecting column is connected to a mounting plate; the two rotating shafts are coaxial; the rotating frame is rotatably connected to the two rotating shafts.

[0010] The rotating frame includes a main frame and a disassembly plate detachably connected to the main frame; the disassembly plate is connected to the main frame by bolts; a first partition corresponding to the wire assembly is connected to the main frame, and a second partition corresponding to the first partition is connected to the disassembly plate; when the main frame and the disassembly plate are connected, a connecting cavity for connecting the wire assembly is formed between the first partition and the second partition corresponding to itself.

[0011] Both the main frame and the disassembly plate are provided with vertical limiting grooves that communicate with the connecting cavity; the front and rear sides of the first guide roller are respectively connected with vertical sliders corresponding to the two vertical limiting grooves, and the first guide roller is vertically slidably connected to the vertical limiting grooves of the main frame and the vertical limiting grooves of the disassembly plate through the two vertical sliders.

[0012] The width of the vertical limiting groove is smaller than the outer diameter of the first spring.

[0013] The limiting device is connected to the mounting plate; the limiting device includes a second spring and a rod; the end of the main frame is connected to a limiting plate corresponding to the limiting device; the limiting plate has two limiting holes distributed 180 degrees around the pivot; one end of the rod passes through the mounting plate and the frame and is inserted into the limiting hole, and the other end of the rod is connected to a handle; one end of the second spring is welded to the handle, and the other end is welded to the mounting plate.

[0014] An extension frame is also connected to the front side below the frame; a connecting shaft is connected to the front end of the extension frame; and a second guide roller corresponding to the first guide roller is connected to the connecting shaft.

[0015] Both sides of the extension frame are provided with longitudinal sliding grooves; the two longitudinal sliding grooves are longitudinally slidably connected with a tensioning device for adjusting the yarn tension.

[0016] The tensioning device includes a mounting shaft, a bushing, and two longitudinal slides; the two longitudinal slides are respectively slidably connected to the two longitudinal slides; the bushing is located between the two longitudinal slides, and a third guide roller corresponding to the first guide roller is rotatably connected to the bushing; one end of the mounting shaft is threaded with a first nut, and the other end passes through the extension frame, the two longitudinal slides, and the bushing and is threaded with a second nut.

[0017] The longitudinal slide is connected to connecting ears on both the upper and lower sides; each connecting ear is threaded with a locking bolt; the bottom end of the locking bolt passes through the connecting ear and abuts against the extension frame.

[0018] The technical effects that this invention can achieve are:

[0019] 1. This invention designs an infrared transmitter and an infrared receiver. In normal operation, the first guide roller located above is pressed down by the preload of the yarn and moves away from the infrared transmitter and receiver, so the infrared receiver can normally receive the infrared rays emitted by the infrared transmitter. However, when a break occurs, the first guide roller located above moves upward due to the force of the first spring and blocks the infrared transmitter and receiver. At this time, the infrared receiver cannot receive the infrared rays emitted by the infrared transmitter, thus identifying a break. Therefore, this invention can detect whether a break has occurred by whether infrared rays are received.

[0020] 2. When the upper first guide roller is damaged, the present invention can rotate the frame 180 degrees to move the lower first guide roller to the upper position. By replacing the upper first guide roller with the lower first guide roller for wire guiding, a rapid replacement can be achieved with high replacement efficiency. Furthermore, by setting a first spring between the two first guide rollers, the present invention can still achieve rapid replacement while the upper first guide roller is pressed down by the yarn preload and moved away from the infrared transmitter and infrared receiver, thus still being able to detect whether a broken thread has occurred.

[0021] 3. The rotating frame of the present invention includes a main frame and a disassembly plate detachably connected to the main frame. When the wire assembly needs to be replaced, the main frame and the disassembly plate can be separated to replace the wire assembly that needs to be replaced, which is more convenient.

[0022] 4. The present invention is provided with an external connecting column, which is threadedly connected to the frame. A limiting device is installed on the mounting plate at the outer end of the external connecting column. The limiting device is inserted into the limiting hole by passing one end of the plug rod through the mounting plate and the frame to limit the rotation of the frame. The connection structure of the limiting device can also prevent the connection between the external connecting column and the frame from becoming loose.

[0023] 5. The present invention also includes a tensioning device, which can adjust the tension of the yarn by moving longitudinally on the longitudinal slide groove. The tensioning device includes a mounting shaft, a bushing, and two longitudinal slides. The mounting shaft, bushing, and two longitudinal slides are connected by a detachable connection structure for easy disassembly. Attached Figure Description

[0039] The invention will now be described in further detail with reference to the accompanying drawings.

[0040] See Figures 1 to 14 .

[0041] A wire frame capable of detecting broken wires includes a frame body 1, on which a rotating frame is rotatably connected. Specifically, both sides of the frame body 1 are threaded with external connecting posts 11, the inner ends of the external connecting posts 11 are connected with rotating shafts 12, and the outer ends of the external connecting posts 11 are connected with mounting plates 13. The two rotating shafts 12 are coaxial, and the rotating frame is rotatably connected to the two rotating shafts 12. Therefore, the rotating frame of this invention can be disassembled. Specifically, during disassembly, it is only necessary to unscrew the two external connecting posts 11, and the rotating frame can be removed.

[0042] The rotating frame is equipped with multiple sets of wire groups, specifically nine sets. The rotating frame has vertical limiting grooves 2 corresponding to the wire groups. Each wire group includes two first guide rollers 3 symmetrically arranged vertically and slidably connected to the vertical limiting grooves 2. A first spring 4 is placed between the two first guide rollers 3. Specifically, the rotating frame includes a main frame 21 and a disassembly plate 22 detachably connected to the main frame 21. The disassembly plate 22 is connected to the main frame 21 by bolts. A first partition plate 23 corresponding to the wire groups is connected to the main frame 21, and a first partition plate 23 corresponding to the wire groups is connected to the disassembly plate 22. The first partition 23 corresponds to the second partition 24; after the main frame 21 is connected to the disassembly plate 22, the first partition 23 and the corresponding second partition 24 form a connecting cavity 25 for connecting the wire assembly; more specifically, both the main frame 21 and the disassembly plate 22 are provided with vertical limiting grooves 2 that communicate with the connecting cavity 25, and the front and rear sides of the first guide roller 3 are respectively connected with vertical sliders 26 corresponding to the two vertical limiting grooves 2. The first guide roller 3 is vertically slidably connected to the vertical limiting grooves 2 of the main frame 21 and the vertical limiting grooves 2 of the disassembly plate 22 through the two vertical sliders 26.

[0043] In the connection of the wire assembly, the two first guide rollers 3 and the first spring 4 are installed between the main frame 21 and the disassembly plate 22, and are limited by the second partition plate 24 and the first partition plate 23. When the first guide rollers 3 and the first spring 4 need to be replaced, simply unscrew the bolts between the main frame 21 and the disassembly plate 22, remove the disassembly plate 22, and disassemble the first guide rollers 3 and the first spring 4 that need to be replaced for replacement. This is relatively convenient. Preferably, the width of the vertical limiting groove 2 is smaller than the outer diameter of the first spring 4 to prevent the first spring 4 from detaching from the vertical limiting groove 2.

[0044] Infrared transmitters 5 and infrared receivers 6 are connected to the upper left and right sides of the frame 1, respectively. The infrared transmitters 5 emit infrared rays to the infrared receivers 6. A limiting device for limiting the rotation of the frame is provided on the side of the frame 1. Specifically, the limiting device is connected to the mounting plate 13 and includes a second spring 31 and a rod 32. A limiting plate 33 corresponding to the limiting device is connected to the end of the main frame 21. The limiting plate 33 has two limiting holes 34 that are distributed 180 degrees around the pivot 12. One end of the rod 32 passes through the mounting plate 13 and the frame 1 and is inserted into the limiting hole 34. The other end of the rod 32 is connected to a handle 35. One end of the second spring 31 is welded to the handle 35 and the other end is welded to the mounting plate 13.

[0045] refer to Figure 3 , 5 In this invention, the outer connecting post 11 is threaded onto the frame 1. When one end of the insertion rod 32 passes through the mounting plate 13 and the frame 1 and is inserted into the limiting insertion hole 34, it can effectively prevent relative rotation between the frame 1 and the outer connecting post 11, thus preventing loosening of the connection between the mounting plate 13 and the frame 1. By designing two limiting insertion holes 34 that are distributed 180 degrees around the axis of the rotating shaft 12, the frame can still be limited after rotating 180 degrees. Therefore, by rotating the frame, this invention can make one of the two first guide rollers 3 of the wire assembly face upwards and be limited by the limiting device.

[0046] In practical use, when the present invention is not connected to a lead wire, the first spring 4 pushes the two first guide rollers 3 of the lead wire assembly to the upper and lower ends of the vertical limiting groove 2 respectively, and the upper first guide roller 3 blocks the infrared transmitter 5 and the infrared receiver 6. At this time, the infrared receiver 6 cannot receive the infrared rays emitted by the infrared transmitter 5; when the present invention is connected to a lead wire (see reference...), Figure 1 , 4 The first guide roller 3 at the top of the conductor group guides the yarn 7, and the first guide roller 3 at the top is pressed down by the preload of the yarn 7 and moves away from the infrared transmitter 5 and the infrared receiver 6. At this time, the infrared receiver 6 can receive the infrared rays emitted by the infrared transmitter 5, and the first spring 4 is compressed.

[0047] The logic for determining whether a yarn is broken in this invention is as follows: When the yarn 7 is being guided normally, the first guide roller 3 located above is pressed down by the preload of the yarn 7 and moves away from the space between the infrared transmitter 5 and the infrared receiver 6. Therefore, the infrared receiver 6 can continuously receive the infrared rays emitted by the infrared transmitter 5, thus determining that the yarn 7 is not broken. However, when one or more yarns 7 break, the first guide roller 3 is pushed upward by the first spring 4 returning to its original state, causing the first guide roller 3 to block the space between the infrared transmitter 5 and the infrared receiver 6. At this time, the infrared receiver 6 cannot receive the infrared rays emitted by the infrared transmitter 5, and it is determined that a yarn 7 has broken and needs to be dealt with urgently. Preferably, this invention can also be equipped with an alarm device. When the infrared receiver 6 cannot receive the infrared rays emitted by the infrared transmitter 5, the alarm device will sound an alarm to remind that the yarn 7 has broken and needs to be dealt with urgently.

[0048] Furthermore, when one or more of the upper first guide rollers 3 are damaged, the lower first guide roller 3 can be rotated to the upper position by flipping the frame 180 degrees. By replacing the upper first guide roller 3 with the lower first guide roller 3 for wire guiding, a rapid replacement can be achieved with high efficiency. In addition, by setting a first spring 4 between the two first guide rollers 3, the invention can still achieve rapid replacement while the upper first guide roller 3 is pressed down by the pretension force of the yarn 5 and moves away from the infrared transmitter 5 and the infrared receiver 6 through the first spring 4. In the event of a yarn breakage, the upper first guide roller 3 can still block the infrared transmitter 5 and the infrared receiver 6, so the function of detecting whether the yarn is broken can still be used.

[0049] Preferably, an extension frame 41 is also connected to the front side of the frame 1 below the present invention. The front end of the extension frame 41 is connected to a connecting shaft 42, and a second guide roller 43 corresponding to the first guide roller 3 is connected to the connecting shaft 42.

[0050] Both sides of the extension frame 41 are provided with longitudinal sliding grooves 51, and tensioning devices for adjusting the tension of yarn 7 are longitudinally slidably connected to the two longitudinal sliding grooves 51. Specifically, the tensioning device includes a mounting shaft 61, a bushing 62, and two longitudinal sliding blocks 63. The two longitudinal sliding blocks 63 are respectively longitudinally slidably connected to the two longitudinal sliding grooves 51. The bushing 62 is located between the two longitudinal sliding blocks 63, and a third guide roller 64 corresponding to the first guide roller 3 is rotatably connected to the bushing 62. A first nut 65 is threaded to one end of the mounting shaft 61, and a second nut 66 is threaded to the other end through the extension frame 41, the two longitudinal sliding blocks 63, and the bushing 62. Specifically, connecting ears 71 are connected to both the upper and lower sides of the longitudinal sliding blocks 63, and locking bolts 72 are threaded to the connecting ears 71. The bottom end of the locking bolt 72 passes through the connecting ears 71 and abuts against the extension frame 41.

[0051] The tensioning device of this invention is slidably connected to two longitudinal slides 51 via two longitudinal slide blocks 63, and the tension of the yarn 7 is adjusted by the longitudinal movement of the tensioning device on the two longitudinal slides 51. Specifically, the closer the tensioning device is to the rotating frame, the greater the tension of the yarn 7; the farther the tensioning device is from the rotating frame, the smaller the tension of the yarn 7. When the tensioning device is in the correct position, it is locked by the locking bolt 72, preventing it from moving on the longitudinal slides 51. In the installation of the mounting shaft 61, bushing 62, and two longitudinal slide blocks 63, the mounting shaft 61, bushing 62, and two longitudinal slide blocks 63 are connected by a detachable connection structure. When disassembly is required, simply unscrew the first nut 65 and the second nut 66, then pull out the mounting shaft 61. At this time, the bushing 62 and the two longitudinal slide blocks 63 can be removed, making disassembly relatively convenient.
