Description

Technical Field

[0001] The utility model relates to a broken yarn detection device for textile, belonging to the technical field of textile. Background Art

[0002] The original meaning of textile is the general term for spinning and weaving. However, with the continuous development and improvement of the textile knowledge system and discipline system, especially after the emergence of technologies such as non-woven textile materials and three-dimensional composite weaving, it is no longer just traditional manual spinning and weaving, but also includes non-woven fabric technology, modern three-dimensional weaving technology, modern electrostatic nano-web forming technology, etc. for the production of clothing, industrial, and decorative textiles. Therefore, modern textile refers to a multi-scale structural processing technology of fibers or fiber aggregates.

[0003] A Chinese published patent (publication number: CN 221028867 U) discloses a broken yarn detection device, which relates to the technical field of textile. It includes a mounting plate, on one side of which there are two wire pressing wheels and at least two tension mechanisms, and adjacent two tension mechanisms are arranged in a staggered and reverse manner; the tension mechanism includes a support frame, in the middle of which there is a rectangular groove vertically, and a slider is slidably arranged in the rectangular groove; on one side of the slider, a winding wheel is rotatably arranged, and the winding wheel and the wire pressing wheel are in the same plane; one end of the slider is connected to one end of the rectangular groove through a compression spring, and the other end of the slider is provided with a contact head, and a contact switch opposite to the contact head is arranged at the other end of the rectangular groove; the compression spring force of one of the tension mechanisms is greater than that of the other tension mechanisms, and the contact switch of this tension mechanism is electrically connected to the alarm of the textile machine, and the contact switches of all tension mechanisms are electrically connected to the shutdown control mechanism of the textile machine. The utility model effectively avoids false alarms caused by the stretching of the spinning yarn by setting multiple tension mechanisms;

[0004] Although the above device can play an automatic detection function when the yarn breaks, due to the certain tension of the yarn itself, after the yarn breaks, the yarn will shrink and wind due to the influence of its own tension. At this time, the operator needs to spend a lot of time to find the yarn end at the broken yarn position before continuing the winding work of the yarn. This process is more cumbersome and will consume more time and labor costs, which is not convenient for the operator to use.

[0005] Therefore, a broken yarn detection device for textile is proposed. Summary of the Utility Model

[0006] In view of this, the utility model provides a broken yarn detection device for textile to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of the utility model is realized as follows: A yarn breakage detection device for textile includes a bottom plate and a support frame. The support frame is fixedly installed at the middle end of the top of the bottom plate. Installation plates are fixedly installed on both the left and right sides of the top of the bottom plate. Electric guiding wheels are movably connected to the front sides of the four installation plates.

[0008] A detection mechanism is arranged at the top of the support frame. The detection mechanism includes springs and a battery box. The two springs are fixedly installed on both the left and right sides of the bottom of the support frame. The bottoms of the two springs are fixedly connected to an L-shaped plate. A driven guiding wheel is movably connected to the front side of the L-shaped plate. The battery box is fixedly installed at the top of the support frame. An induction switch is fixedly installed at the middle end of the bottom of the support frame. The induction switch is electrically connected to the output end of the battery box. An alarm sounder is electrically connected to the output end of the front side of the battery box.

[0009] Clamping mechanisms are arranged on both the left and right sides of the top of the bottom plate. The clamping mechanisms include support platforms. The two support platforms are fixedly installed on both the left and right sides of the top of the bottom plate. Electric cylinders are fixedly installed on the tops of the two support platforms. Push plates are fixedly installed at the bottoms of the two electric cylinders. Main toothed plates are fixedly installed at the bottoms of the two push plates. Brackets are fixedly installed on both the left and right sides of the top of the bottom plate. Sub toothed plates are fixedly installed on the tops of the two brackets.

[0010] Further preferably, connecting rods are fixedly installed on both the left and right sides of the top of the L-shaped plate and inside the two springs. Connection plates are fixedly installed at the tops of the two connecting rods.

[0011] Further preferably, a first power line is electrically connected to the input end of the top of the battery box. The end of the first power line far from the battery box is electrically connected to an external power source.

[0012] Further preferably, slots are opened on both the left and right sides of the surface of the support frame. The two connecting rods penetrate through the inner cavities of the two slots and extend to the top of the support frame.

[0013] Further preferably, sliding rods are fixedly installed on both the left and right sides of the top of the support frame. The two connection plates are slidably connected to the surfaces of the two sliding rods.

[0014] Further preferably, second power lines are electrically connected to the input ends of the two electric cylinders. The ends of the two second power lines far from the two electric cylinders are electrically connected to the output ends on both sides of the battery box.

[0015] Further preferably, moving grooves are opened on the front sides of the two support platforms. The rear sides of the two push plates are slidably connected to the inner cavities of the two moving grooves.

[0016] Further preferably, fixing bolts are threadedly connected to the four peripheries of the top of the bottom plate, and the four fixing bolts are threadedly connected to the inner surface of the textile machine.

[0017] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:

[0018] 1. By setting up a detection mechanism in the present invention, the yarn passes through the top of the surface of the driven guide wheel and drives the driven guide wheel to move downward through the tension. At this time, the spring is stretched. When the yarn breaks, the spring pulls the L-shaped plate to move upward through its own tension. At this time, the top of the L-shaped plate contacts the induction switch, and the power in the battery box is output. At this time, the alarm sound generates an alarm due to the output of the power in the battery box, thereby reminding the operator that the yarn has broken. By automatically detecting the broken yarn of the yarn, the speed and efficiency of the operator to discover the broken yarn situation can be improved, and it is avoided that the yarn is not discovered for a long time after breaking, thus affecting the normal winding work of the yarn. By setting up the support frame and outputting the power of the battery box, the electric cylinder drives the push plate and the main tooth plate to press down. At this time, the main tooth plate contacts the sub-tooth plate, and clamps the yarn passing through the inner sides of the main tooth plate and the sub-tooth plate, effectively saving the time and labor cost consumed by the operator to find the broken place of the yarn due to the influence of the self-tension of the yarn after the yarn breaks, and improving the convenience of using the equipment.

[0019] 2. By setting up the first power cord in the present invention, it is convenient for an external power source to provide power to the battery box in real time, so as to facilitate the battery box to drive other components to detect and break the yarn. By setting up the slot, the movement of the connecting rod can be limited, avoiding the situation that the connecting rod moves and generates an offset, resulting in the L-shaped plate not being able to contact the induction switch. By setting up the sliding rod, the limitation of the movement of the L-shaped plate can be further improved, ensuring that the L-shaped plate can accurately contact the induction switch. By setting up the moving slot, the direction of the movement of the push plate can be limited, avoiding the problem that the push plate moves and generates an offset, resulting in the inability to clamp the yarn. By setting up the fixing bolts, the whole equipment can be installed and disassembled, facilitating the daily maintenance of the components in the equipment.

[0020] The above summary is only for the purpose of the specification and is not intended to be limiting in any way. In addition to the above-described illustrative aspects, embodiments and features, further aspects, embodiments and features of the present invention will be readily apparent by reference to the drawings and the following detailed description.

Detailed implementation manners

[0028] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0029] The following will describe the embodiments of the present utility model in detail with reference to the drawings.

[0030] Embodiment 1

[0031] As Figures 1-5As shown in the figure, an embodiment of the utility model provides a broken yarn detection device for textile, which includes a bottom plate 1 and a support frame 3. The support frame 3 is fixedly installed at the middle end of the top of the bottom plate 1. Installation plates 4 are fixedly installed on both the left and right sides of the top of the bottom plate 1. Electric guide wheels 5 are movably connected to the front sides of the four installation plates 4.

[0032] A detection mechanism 2 is arranged at the top of the support frame 3. The detection mechanism 2 includes springs 201 and a battery box 207. The two springs 201 are fixedly installed on both the left and right sides of the bottom of the support frame 3. The bottoms of the two springs 201 are fixedly connected to an L-shaped plate 202. A driven guide wheel 203 is movably connected to the front side of the L-shaped plate 202. The battery box 207 is fixedly installed at the top of the support frame 3. An induction switch 208 is fixedly installed at the middle end of the bottom of the support frame 3. The induction switch 208 is electrically connected to the output end of the battery box 207. An alarm sounder 209 is electrically connected to the output end at the front side of the battery box 207. Connecting rods 204 are fixedly installed on both the left and right sides of the top of the L-shaped plate 202 and inside the two springs 201. Connection plates 205 are fixedly installed at the tops of the two connecting rods 204. A first power line 210 is electrically connected to the input end at the top of the battery box 207. One end of the first power line 210 away from the battery box 207 is electrically connected to an external power supply. Slots 211 are formed on both the left and right sides of the surface of the support frame 3. The two connecting rods 204 penetrate through the inner cavities of the two slots 211 and extend to the top of the support frame 3. Slide rods 206 are fixedly installed on both the left and right sides of the top of the support frame 3. The two connection plates 205 are slidably connected to the surfaces of the two slide rods 206.

[0033] By setting up the detection mechanism 2, the yarn passes through the top of the surface of the driven guide wheel 203 and drives the driven guide wheel 203 to move downward through the tension. At this time, the spring 201 is stretched. When the yarn breaks, the spring 201 pulls the L-shaped plate 202 to move upward through its own tension. At this time, the top of the L-shaped plate 202 contacts the induction switch 208, and the power in the battery box 207 is output. At this time, the alarm sound 209 generates an alarm due to the output of the power in the battery box 207, thereby reminding the operator that the yarn has broken. Through the automatic broken yarn detection of the yarn, the speed and efficiency of the operator to discover the broken yarn situation can be improved, and the situation that the yarn is not discovered for a long time after breaking, thus affecting the normal winding work of the yarn, can be avoided. By setting up the first power cord 210, it is convenient for the external power supply to provide power to the battery box 207 in real time, so as to facilitate the battery box 207 to drive other components to detect the yarn and work on breaking the line. By setting up the slot 211, the movement of the connecting rod 204 can be limited, avoiding the situation that the connecting rod 204 moves offset when moving, resulting in the L-shaped plate 202 not being able to contact the induction switch 208. By setting up the slide bar 206, the limitation of the movement of the L-shaped plate 202 can be further improved, ensuring that the L-shaped plate 202 can accurately contact the induction switch 208.

[0034] Embodiment 2

[0035] In one embodiment, clamping mechanisms 7 are arranged on the left and right sides of the top of the base plate 1. The clamping mechanism 7 includes a support table 701. The two support tables 701 are fixedly installed on the left and right sides of the top of the base plate 1. Electric cylinders 702 are fixedly installed on the tops of the two support tables 701. Push plates 703 are fixedly installed at the bottoms of the two electric cylinders 702. Main toothed plates 704 are fixedly installed at the bottoms of the two push plates 703. Brackets 705 are fixedly installed on the left and right sides of the top of the base plate 1. Sub toothed plates 706 are fixedly installed on the tops of the two brackets 705. The input ends of the two electric cylinders 702 are electrically connected to the second power cords 708. One ends of the two second power cords 708 far from the two electric cylinders 702 are electrically connected to the output ends on the left and right sides of the battery box 207. Moving grooves 707 are opened on the front sides of the two support tables 701. The rear sides of the two push plates 703 are slidably connected to the inner cavities of the two moving grooves 707. Fixing bolts 6 are threadedly connected to the periphery of the top of the base plate 1. The four fixing bolts 6 are threadedly connected to the inner surface of the textile machine.

[0036] By setting the support frame 3 to output power through the battery box 207, the electric cylinder 702 drives the push plate 703 and the main tooth plate 704 to perform a pressing operation. At this time, the main tooth plate 704 contacts the sub-tooth plate 706, and clamps the yarn passing through the inner sides of the main tooth plate 704 and the sub-tooth plate 706, effectively saving the time and labor cost consumed by the operator to find the yarn breakage due to the winding of the yarn under the influence of its own tension after the yarn breaks, and improving the convenience of using the equipment. By setting the moving groove 707, the direction of the push plate 703 during movement can be limited to avoid the problem that the push plate 703 deviates during movement and thus cannot clamp the yarn. By setting the fixing bolt 6, the whole equipment can be installed and disassembled, which is convenient for the daily maintenance of the components in the equipment.

[0037] When the present utility model is working: when the yarn breaks, since the downward pressure exerted by the yarn tension on the surface of the driven guide wheel 203 disappears, at this time the spring 201 drives the L-shaped plate 202 to move upward through its own pulling force. At this time, the L-shaped plate 202 contacts the induction switch 208, and the battery box 207 is opened to output power. At this time, the alarm sound 209 generates an alarm operation through the output of the battery box 207, thereby completing the detection work of the yarn breakage. At the same time, due to the output of the battery box 207, the induction switch 208 transmits the power to the electric cylinder 702. The electric cylinder 702 drives the push plate 703 and the main tooth plate 704 to move downward, and the main tooth plate 704 and the sub-tooth plate 706 are engaged with each other, and automatically clamp the yarn passing through the middle of the main tooth plate 704 and the sub-tooth plate 706, thereby completing the clamping work of the broken yarn.

[0038] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
