Description

TECHNICAL FIELD

[0001] The utility model relates to a broken line detection device field, specifically to a high precision broken line detection device for weaving. BACKGROUND

[0002] In the process of weaving process, hundreds of anti-lines are transported and advanced in the weaving equipment at the same time, and in this process, if there is a broken line, it will affect the whole weaving process, and if the broken line cannot be found in time, it will not only affect the whole weaving process, but also cause defects in the final textile product.

[0003] In view of the above situation, many broken line detection devices for weaving equipment have appeared on the market, which can cut off the power supply of the weaving equipment and send an alarm when a broken line is found. The most common broken line detection device on the market is a laser detection device, which mainly consists of a laser emitter and a laser receiver. When a broken line occurs, the line segment falls and blocks the laser emitted by the laser emitter, and the laser receiver will cut off the power supply of the weaving equipment and send an alarm after sensing the interruption of the laser.

[0005] But the scheme including the above-mentioned patent, the broken line detection device using laser to detect on the market has a obvious problem, that is, because the yarn moves in a straight line during the movement, it often jumps or tilts with the movement, in this case, the jumping and tilting yarn will also block the laser, and thus the broken line detection device will send a false alarm. SUMMARY

[0006] In order to overcome the false alarm of the textile broken end detection device using laser detection in the prior art, the utility model provides a high-precision broken end detection device for textile.

[0010] A second conductive part is horizontally arranged and connected to the left and right insulation support bases at both ends.

[0011] A plurality of metal suspension rod parts are vertically arranged and have suspension holes passing through the left and right sides.

[0012] When the yarn passes through the suspension hole, the yarn acts on the metal suspension rod part to maintain it in the first position.

[0013] When the yarn is disconnected and separated from the suspension hole, the yarn no longer acts on the metal suspension rod part.

[0014] Further, the first conductive part is a metal plate, which includes a support part on the upper side and a connecting part on the lower side.

[0015] Further, the insulating support seat is provided with an embedding groove facing the first conductive part, the connecting part of the first conductive part is clamped and matched in the embedding groove, the surface of the insulating support seat is also provided with a first threaded hole, the first threaded hole is communicated with the embedding groove, and a first bolt is also connected in the first threaded hole in a threaded matching mode; when the first bolt is screwed in the first threaded hole, the rod part of the first bolt can be inserted into the embedding groove and abuts against the connecting part of the first conductive part, so that the connecting part of the first conductive part is prevented from being separated from the embedding groove.

[0016] Further, the second conductive part comprises two metal cylinders connected to the insulating support seat and a metal rope, the metal cylinder is provided with a connecting hole, the end of the metal rope is arranged in the connecting hole, the side wall of the metal cylinder is also provided with a second threaded hole, the second threaded hole is communicated with the connecting hole, and a second bolt is also connected in the second threaded hole in a threaded matching mode; when the second bolt is screwed in the second threaded hole, the rod part of the second bolt can be inserted into the connecting hole and abuts against the end of the metal rope, so that the end of the metal rope is prevented from being separated from the connecting hole.

[0017] Further, one end of the metal cylinder is also provided with a threaded column, the insulating support seat is provided with a third threaded hole, and the metal cylinder is connected to the insulating support seat in a threaded matching mode of the threaded column and the third threaded hole.

[0018] Further, the metal suspension rod part is a metal sheet, and the suspension hole is a long hole arranged along the length direction of the metal suspension rod part.

[0019] Further, the upper end of the metal suspension rod part is also provided with a plurality of limiting components, the limiting components are symmetrically arranged on the two sides of the suspension hole, each limiting component comprises two soft rubber blocks, and a through gap for the spinning line to pass through is arranged between the two soft rubber blocks of the limiting component.

[0020] Further, the first conductive part is provided with a conductive hole, the wire core of the first electric wire is arranged in and welded in the conductive hole; the threaded column part of the metal cylinder of the second conductive part is exposed outside the insulating support seat, and the wire core of the second electric wire is bound and welded on the exposed threaded column.

[0021] Further, the insulating support seat is also provided with a plurality of bolt holes, a third bolt is arranged in the bolt hole, and the insulating support seat can be connected to the textile equipment through the third bolt.

[0022] The line break detection process of the utility model discloses:

[0023] First, the first and second conductive parts are connected to the control device of the textile equipment through the first and second wires, and then each thread is passed through the suspension hole of the metal suspension rod, and the control device of the textile equipment provides a continuous current to the first conductive part through the first wire during the textile process;

[0024] When there is no thread breakage, each metal suspension rod is in the first position state under the action of the thread force, and thus the first and second conductive parts are not in contact with each other, so that the first and second conductive parts cannot be conducted.

[0025] When there is thread breakage, the metal suspension rod corresponding to the thread loses the resistance provided by the thread, and thus the metal suspension rod moves downward under the action of gravity. The metal suspension rod falls to the abutment between the support part of the first conductive part and the upper end inner hole wall of the suspension hole, and thus the metal suspension rod is stopped by the first conductive part and the outer side wall of the metal suspension rod is in abutment with the second conductive part. At this time, the metal suspension rod has moved to the second position state, so that the metal suspension rod is in contact with the first and second conductive parts, and the first and second conductive parts are conducted through the metal suspension rod. The current on the first conductive part flows to the second conductive part, and then flows back to the control device of the textile equipment through the second wire. The control device cuts off the power supply of the entire textile equipment to prevent further textile and waste.

[0026] The beneficial effects of the utility model lie in:

[0027] 1. The first and second conductive parts are provided, and a metal suspension rod is arranged between the first and second conductive parts. When a thread passes through the metal suspension rod, the thread can maintain dynamic balance under the action of the thread and be in the first position state, so that the first and second conductive parts are not conducted. When the thread breaks the metal suspension rod, the metal suspension rod falls and comes into contact with the first and second conductive parts, so that the first and second conductive parts are conducted. Therefore, the breakage of the thread can be accurately judged by detecting the conduction between the first and second conductive parts, so that the detection accuracy of the device is effectively improved and false positives do not occur.

[0028] 2. The limiting assembly is arranged on the metal suspension rod to limit the up and down movement of the thread relative to the metal suspension rod, so that the thread breakage caused by frequent friction with the metal suspension rod can be effectively prevented.

[0029] 3. The first and second conductive parts are installed on the insulating support seat in a simple manner, and the insulating support seat is installed on the textile equipment in a simple manner, so that the installation difficulty of the device can be effectively reduced.

The first conductive part 2 is horizontally arranged and connected with the left and right insulating support seats 1 at both ends. The first conductive part 2 is electrically connected with the control device of the spinning equipment through a first wire 3. The second conductive part 4 is horizontally arranged and connected with the left and right insulating support seats 1 at both ends. The second conductive part 4 is located below the first conductive part 2 and is electrically connected with the control device of the spinning equipment through a second wire 5. The metal suspension rod part 6 is vertically arranged and has a suspension hole 61 passing through the left and right sides. The first conductive part 2 passes through the suspension hole 61 horizontally, and the spinning thread 10 can also pass through the suspension hole 61. The metal suspension rod part 6 always has a downward movement trend under the action of gravity. When the spinning thread 10 passes through the suspension hole 61, the spinning thread 10 acts on the metal suspension rod part 6 to maintain it in a first position state a. In this position state, the first conductive part 2 passes through the middle of the suspension hole 61, and the metal suspension rod part 6 is vertically suspended above the second conductive part 4. The metal suspension rod part 6 does not contact the first conductive part 2 and the second conductive part 4. When the spinning thread 10 is disconnected and separated from the suspension hole 61, the action of the spinning thread 10 on the metal suspension rod part 6 is removed. The metal suspension rod part 6 moves to a second position state b under the action of gravity. In this position state, the first conductive part 2 contacts the inner hole wall of the suspension hole 61, the second conductive part 4 contacts the outer side wall of the metal suspension rod part 6, and the first conductive part 2 and the second conductive part 4 are conductive through the metal suspension rod part 6.

The surface of the insulating support base 1 also has a first threaded hole 12, and the first threaded hole 12 communicates with the insertion groove 11. A first bolt 7 is also connected to the first threaded hole 12 by thread engagement. When the first bolt 7 is tightened in the first threaded hole 12, the shank of the first bolt 7 can extend into the insertion groove 11 and abut against the connecting part 22 of the first conductive element 2 to prevent the two ends of the connecting part 22 of the first conductive element 2 from disengaging from the insertion groove 11.

[0056] Combination Figures 1 to 3 as well as Figure 5 As shown, in this embodiment, the second conductive element 4 includes two metal cylinders 41 connected to the insulating support base 1 and a metal rope 42. The metal cylinders 41 have connecting holes 411, and the end of the metal rope 42 passes through the connecting holes 411. The side wall of the metal cylinders 41 also has a second threaded hole 412, which communicates with the connecting holes 411. A second bolt 8 is also connected to the second threaded hole 412 by a threaded engagement. When the second bolt 8 is tightened into the second threaded hole 412, the shank of the second bolt 8 can extend into the connecting hole 411 and abut against the end of the metal rope 42 to prevent the end of the metal rope 42 from detaching from the connecting hole 411.

[0057] Combination Figure 1 , Figure 2 and Figure 7 As shown, in this embodiment, one end of the metal cylinder 41 is also provided with a threaded post 413, and the insulating support 1 is provided with a third threaded hole 13. The metal cylinder 41 is connected to the insulating support 1 by the threaded engagement of the threaded post 413 and the third threaded hole 13.

[0058] Combination Figures 1 to 3 as well as Figure 6 As shown, in this embodiment, the metal suspension member 6 is configured as a thin metal sheet, and the suspension hole 61 is an elongated hole opened along the length direction of the metal suspension member 6.

[0059] Among them, such as Figure 6 As shown in the figure, in this embodiment, a number of limiting components are also provided on both sides of the upper end of the metal suspension member 6, and the limiting components are symmetrically distributed on both sides of the suspension hole 61. Each limiting component is composed of two soft rubber blocks 62, and a passage gap 63 for the spinning thread 10 to pass through is also provided between the two soft rubber blocks 62 of the limiting component.

[0060] Combination Figure 1 ,Figure 2 and Figure 4 As shown in FIG. 1, in this embodiment, the first conductive member 2 is provided with a conductive hole 23, and the core of the first electric wire 3 is inserted into and welded in the conductive hole 23; the threaded column 413 of the metal cylinder 41 of the second conductive member 4 is partially exposed outside the insulating support base 1, and the core of the second electric wire 5 is bound and welded on the exposed threaded column 413.

[0062] The broken wire detection process of this embodiment:

[0063] First, the first conductive member 2 and the second conductive member 4 are connected to the control device of the textile equipment through the first electric wire 3 and the second electric wire 5 respectively, then each yarn 10 is inserted through the hanging hole 61 of the metal suspension rod member 6, and then the control device of the textile equipment continuously provides current to the first conductive member 2 through the first electric wire 3 during the textile process;

[0064] When no yarn 10 is broken, each metal suspension rod member 6 is in the first position state a under the action of the yarn 10, and thus each metal suspension rod member 6 does not contact the first conductive member 2 and the second conductive member 4, so the first conductive member 2 and the second conductive member 4 cannot be conducted;

[0065] When a yarn 10 is broken, the metal suspension rod member 6 corresponding to the yarn 10 loses the resistance provided by the yarn 10, so the metal suspension rod member 6 moves downward under the action of gravity, and the metal suspension rod member 6 falls to the abutment between the support part 21 of the first conductive member 2 and the upper end inner hole wall of the hanging hole 61, at this time the metal suspension rod member 6 is stopped from falling by the first conductive member 2, and the outer side wall of the metal suspension rod member 6 also abuts against the second conductive member 4, at this time the metal suspension rod member 6 has moved to the second position state b, so that the metal suspension rod member 6 contacts the first conductive member 2 and the second conductive member 4, and the first conductive member 2 and the second conductive member 4 are conducted through the metal suspension rod member 6, and the current on the first conductive member 2 flows to the second conductive member 4, and then flows back to the control device of the textile equipment through the second electric wire 5, and the control device cuts off the power supply of the entire textile equipment to prevent further textile and waste.

[0066] The advantage of the embodiment is that whether the wire is broken is determined according to the conduction between the first conductive part and the second conductive part, compared with the laser detection on the market, the detection accuracy of the device is higher, false positives do not occur, and the production efficiency of the entire textile process can be effectively improved.

[0067] Embodiment two

[0068] Referring to Figure 8 and Figure 9 The embodiment further illustrates the actual application and state change of the device in Embodiment One.

[0069] As shown in Figure 8 In the embodiment, each of the yarns 10 passes through the hanging hole 61 of the metal suspension rod 6 from back to front, and the yarn 10 passes from one side of the metal suspension rod 6 to the other side, so that the yarn 10 can act on the upper end of the metal suspension rod 6 and provide resistance to the metal suspension rod 6.

[0070] As shown in Figure 9 In the embodiment, when the yarn 10 is broken, the metal suspension rod 6 falls under the action of gravity and interferes with the upper hole wall of the hanging hole 61 until the first conductive part 2 interferes with the upper hole wall of the hanging hole 61, and the metal suspension rod 6 also interferes with one side of the second conductive part 4.

[0071] The embodiment is a further supplement to Embodiment One, and the remaining structure, method and advantages of the embodiment are consistent with Embodiment One, and will not be repeated here.

[0072] The above specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model, and those skilled in the art can make modifications without creative contribution according to the needs after reading the specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
