Description

Technical Field

[0001] This utility model belongs to the field of auxiliary equipment for automatic splicing devices in rotor spinning machines, specifically relating to a yarn breakage sensor for rotor spinning machines. Background Technology

[0002] The yarn breakage sensor is an important device for the automatic splicing device of the rotor spinning machine to achieve automated control. It is used to detect whether the yarn is broken. When the yarn breakage sensor detects a yarn breakage, it will send a yarn breakage signal and feed the signal back to the main control system of the automatic splicing device. Then the automatic splicing device will start to perform automatic splicing.

[0003] Existing yarn breakage sensors are mounted on the frame of rotor spinning machines via mounting plates. Typically, a ceramic yarn guide is integrated into the sensor body, with a detection device located below it. The ceramic yarn guide and detection device are aligned vertically. The yarn passes sequentially through the yarn guide's hole and the yarn breakage sensor's detection device, and the detection device then checks for yarn breakage. However, because the ceramic yarn guide is manually glued to the yarn breakage sensor, the stress from the frequent automatic splicing process can cause it to shift position. If its position becomes misaligned with the detection device, the device will be unable to detect yarn breakage properly, affecting the normal operation of the entire rotor spinning machine. Furthermore, the detection device consists of various electronic control components, and friction during yarn passage through the yarn breakage sensor generates dust and lint. The accumulation of this dust and lint interferes with the normal operation of the detection device. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a yarn breakage sensor for a rotor spinning machine. The bonding and installation of the ceramic yarn feeder is improved by using a mechanical pressing structure. Furthermore, a yarn feeder channel is used to seal and separate the yarn breakage detection area from the detection component body. This solves the problem that the detection capability of the yarn breakage sensor decreases after long-term use, which affects the normal working efficiency of the rotor spinning machine.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A yarn breakage sensor for a rotor spinning machine is applied in the automatic splicing device of the rotor spinning machine. The rotor spinning machine includes several spinning stations and a frame body on which the spinning stations are installed. Each spinning station includes an automatic splicing device and a yarn breakage sensor that are installed together. The yarn breakage sensor is mounted on the frame body via a U-shaped mounting plate. The yarn breakage sensor includes:

[0007] A housing assembly includes a lower housing and an upper housing. The lower housing has a first opening, and a set of first grooves are provided on the side walls of the first opening. The upper housing is a hollow, bottomless box, and the lower housing is embedded and fastened to the bottom of the upper housing. The upper housing is composed of an integrally formed working part and a mounting part. The upper surface of the working part has a second groove at the position corresponding to the first opening, and a second opening is provided at the bottom of the second groove. Based on the above structure, a notch is provided on the side wall of the working part. When the upper housing and the lower housing are fastened together, the notch connects the first opening and the second opening.

[0008] The working assembly includes a set of ceramic wire guides, each of which has a wire guide hole. The opening of the wire guide hole expands outward to form a trumpet-shaped structure, and the structural shape of each ceramic wire guide is the same. Any one ceramic wire guide is fitted into a set of first grooves, and the opening direction of the wire guide hole in the ceramic wire guide faces the notch. In this case, the ceramic wire guide is configured as the first ceramic wire guide. Furthermore, another ceramic wire guide is fitted into a second groove, and the opening direction of the wire guide hole also faces the notch. In this case, the ceramic wire guide is configured as the second ceramic wire guide. The wire guide holes in the first and second ceramic wire guides are on the same straight line in the vertical direction.

[0009] Based on this, the working component also includes a yarn passage located above the first ceramic yarn passer. The yarn passage is a columnar channel with an opening on the side wall, and the material of the yarn passage is transparent glass. In addition, the opening on the side wall of the yarn passage is connected to the notch, the top of the yarn passage is abutted against the bottom of the second opening, and the bottom of the yarn passage is abutted against the upper surface of the first ceramic yarn passer. At this time, the yarn passes through the yarn passage hole on the second ceramic yarn passer and enters the yarn passage, and then exits through the yarn passage hole on the first ceramic yarn passer.

[0010] The detection component includes a laser emitting device and a receiving device. The laser emitting device and the receiving device are respectively mounted on both sides of the yarn passage via mounting bases. The mounting bases are located inside the upper housing. At this time, a detection area is formed between the laser emitting device and the receiving device, and the detection area intersects with the yarn. Whether the receiving device can receive the laser emitted by the laser emitting device is used to determine whether the yarn is broken and to generate a detection signal.

[0011] The control component includes a mounting base plate disposed on the lower housing and a circuit board disposed on the mounting base plate. After receiving a detection signal from the detection component, the circuit board sends a control signal to the automatic connector device to start the automatic connector operation.

[0012] Preferably, in the housing assembly, the lower housing further includes an n-shaped fastening part integrally connected to the lower housing, the n-shaped fastening part covering and fastening above a portion of the first opening, the port of the n-shaped fastening part being perpendicular to the surface of the lower housing, and the port of the n-shaped fastening part facing the notch;

[0013] In addition, a first limiting part is provided on one side of each of the first grooves on the lower housing;

[0014] In addition, the upper surface of the lower shell is provided with crisscrossing reinforcing ribs.

[0015] More preferably, in the upper housing, a second limiting part is provided around the position of the notch, and a third groove exists between the second limiting part and the body of the upper housing, and the third groove cooperates with the side wall opening of the wire passage.

[0016] In addition, the lower surface of the upper shell is also provided with crisscrossing reinforcing ribs. Based on this, the upper shell is fixedly connected to the lower shell by a number of screws.

[0017] Furthermore, in the working assembly, a third opening is provided on one side wall of the wire passage, the third opening cooperating with the port of the n-shaped fastening part, and forming a dust-reducing channel with the n-shaped fastening part.

[0018] Furthermore, the working component also includes a guide plate that is screwed to the top of the upper housing. The guide plate has a guide hole, which is aligned with the two thread-passing holes in the vertical direction. The opening of the guide hole also expands outward to form a trumpet-shaped structure, and the opening direction is the same as the opening direction of the thread-passing holes.

[0019] The guide plate, while completely covering the working part, extends towards the mounting part, forming a mounting gap between the guide plate and the mounting part. The distance of the mounting gap is the height difference between the mounting part and the working part in the upper housing. One side of the U-shaped mounting plate is inserted into the mounting gap and connected to the guide plate by bolts.

[0020] The beneficial effects of this utility model are as follows:

[0021] In general, the yarn breakage sensor provided by this utility model configures two ceramic yarn feeders. The two ceramic yarn feeders are assembled by utilizing the fit between the first opening in the lower housing and a set of first grooves, and the fit between the second groove in the upper housing and the second opening. Based on the interlocking of the upper and lower housings, the horizontal position of the two ceramic yarn feeders is defined. Furthermore, a guide plate is provided on the top of the upper housing, and a yarn feed channel is provided between the upper and lower housings. The top of the yarn feed channel abuts against the bottom of the second opening, and the bottom of the yarn feed channel abuts against the upper surface of the first ceramic yarn feeder. This achieves vertical positioning of the two ceramic yarn feeders by the yarn breakage sensor, preventing the position of the ceramic yarn feeders from loosening or changing due to prolonged use.

[0022] Based on this, the laser emitting device and receiving device in the detection component are installed on both sides of the yarn feeding channel, and the yarn passes through the detection area in the yarn feeding channel, realizing the relative sealing and separation between the yarn and the detection component. In addition, the dust removal channel is set up to avoid the accumulation of dust and fly waste, which would reduce the detection effect of the detection component and avoid affecting the normal operation of the rotor spinning machine.

[0034] The solution provided by this utility model will now be described in detail with reference to the accompanying drawings.

[0035] In this technical solution, such as Figure 1-3As shown, a yarn breakage sensor for a rotor spinning machine is applied to the automatic splicing device of the rotor spinning machine. The rotor spinning machine includes several spinning stations and a frame body that coordinates the spinning stations. Each spinning station includes an automatic splicing device and a yarn breakage sensor 1. The automatic splicing device is a commonly used device in the textile industry for rotor spinning machines. Its working principle is as follows: under the control of the rotor spinning machine's main control system, when the working yarn in the spinning station breaks, the main control system controls the automatic splicing device to perform an automatic splicing action. The yarn breakage sensor 1 provided in this application is a device used in rotor spinning machines to detect whether the yarn is broken. The yarn breakage sensor 1 is mounted on the frame body via a U-shaped mounting plate 2. The yarn breakage sensor 1 includes: a housing assembly 3, a working assembly 4, a detection assembly 5, and a control assembly.

[0036] like Figure 2 , Figure 4-8 As shown, the housing assembly 3 includes a lower housing 6 and an upper housing 7, and the upper housing 7 is fixedly connected to the lower housing 6 by a number of screws. The lower housing 6 has a first opening 601, and a set of first grooves 602 are provided on the side walls of the first opening 601. The upper housing 7 is a hollow bottomless box, and the lower housing 6 is embedded and fastened to the bottom of the upper housing 7. The upper housing 7 is composed of an integrally formed working part 701 and a mounting part 702. The upper surface of the working part 701 has a second groove 703 at the position corresponding to the first opening 601, and a second opening 704 is provided at the bottom of the second groove 703.

[0037] Based on this, a notch 705 is provided on the side wall of the working part 701. When the upper housing 7 and the lower housing 6 are engaged with each other, the notch 705 connects the first opening 601 and the second opening 704.

[0038] Based on the above embodiments, the housing assembly 3 is the mounting base for the overall structure of the yarn breakage sensor 1. The first opening 601, the second opening 704, and the notch 705 are the basis for the use of the yarn breakage sensor 1. The following will be specifically described in conjunction with the setting of the working component 4 in the yarn breakage sensor 1.

[0039] like Figure 2 , Figure 5-7 As shown, the working component 4 includes a set of ceramic wire feeders 401. Each ceramic wire feeder 401 is provided with a wire feed hole 402. The opening of the wire feed hole 402 expands outward to form a trumpet-shaped structure, and the structural shape of each ceramic wire feeder 401 is the same.

[0040] In this configuration, any one of the ceramic wire feeders 401 is fitted into a set of first grooves 602, and the opening direction of the wire feeder hole 402 in the ceramic wire feeder 401 faces the notch 705. At this time, the ceramic wire feeder 401 is configured as the first ceramic wire feeder.

[0041] In addition, another ceramic wire feeder 401 is fitted in the second groove 703, and the opening direction of the wire feed hole 402 is also facing the notch 705. At this time, the ceramic wire feeder 401 is configured as the second ceramic wire feeder, and the wire feed hole 402 in the first ceramic wire feeder and the wire feed hole 402 in the second ceramic wire feeder are on the same straight line in the vertical direction.

[0042] Based on this, the working component 4 also includes a wire passage 403 located above the first ceramic wire passer. The wire passage 403 is a columnar channel with an opening on the side wall, and the material of the wire passage 403 is transparent glass. In addition, the opening on the side wall of the wire passage 403 is connected to the notch 705, the top of the wire passage 403 is in contact with the bottom of the second opening 704, and the bottom of the wire passage 403 is in contact with the upper surface of the first ceramic wire passer.

[0043] In the above structure, the wire passage 403 is also limited by several limiting parts. In the lower housing 6, a first limiting part 605 is provided on one side of each first groove 602. In the upper housing 7, a second limiting part 706 is provided around the position of the notch 705. There is a third groove between the second limiting part 706 and the body of the upper housing 7, and the third groove cooperates with the side wall opening of the wire passage 403.

[0044] In addition, such as Figure 1-2 As shown, the working component 4 also includes a guide plate 9 that is screwed to the top of the upper housing 7. The guide plate 9 has a guide hole 901. The guide hole 901 and the two thread holes 402 are in the same straight line in the vertical direction. The opening of the guide hole 901 also expands outward to form a trumpet-shaped structure, and the opening direction is the same as the opening direction of the thread holes 402.

[0045] Based on the above embodiments, after the yarn passes through the guide hole 901, it enters the yarn passage 403 through the yarn passage hole 402 on the second ceramic yarn guide and exits through the yarn passage hole 402 on the first ceramic yarn guide. The assembly of the first ceramic yarn guide, the second ceramic yarn guide, and the housing assembly 3 is composed of mutual pressing fit of each structure. Specifically: the first ceramic yarn guide is fitted and installed in a set of first grooves 602; the yarn passage 403 is provided on the upper surface of the first ceramic yarn guide; the second opening 704 on the upper housing 7 abuts against the top of the yarn passage 403; the second ceramic yarn guide is fitted and installed in the second groove 703; the guide plate 9 is provided on the top of the upper housing 7 by screws. Thus, the yarn breakage sensor 1 is installed in a pressing fit with the two ceramic yarn guides 401, preventing the position of the ceramic yarn guides 401 from loosening or changing due to long-term use of the yarn breakage sensor 1.

[0046] Based on the above structure, the guide plate 9, while completely covering the working part 701, extends towards the mounting part 702, creating a mounting gap between the guide plate 9 and the mounting part 702. This mounting gap is equal to the height difference between the mounting part 702 and the working part 701 in the upper housing 7. One side of the U-shaped mounting plate 2 is inserted into this mounting gap and connected to the guide plate 9 by bolts. The specific structure is as follows: Figure 1-3 As shown.

[0047] It should be noted that, based on the above-described scheme of overall installation of the yarn breakage sensor 1 and press-fit installation of the two ceramic yarn feeders 401, this utility model utilizes the cooperation between the detection component 5 and the control component to realize the detection action of the yarn breakage sensor 1, such as... Figure 6 As shown, the detection component 5 includes a laser emitting device 501 and a receiving device 502. The laser emitting device 501 and the receiving device 502 are respectively disposed on both sides of the wire passage 403 via mounting bases 503. The mounting bases 503 are disposed inside the upper housing 7.

[0048] Based on the above embodiments, a detection area is formed between the laser emitting device 501 and the receiving device 502, and the detection area intersects with the yarn. Whether the receiving device 502 can receive the laser emitted by the laser emitting device 501 is used to determine whether the yarn is broken and a detection signal is generated.

[0049] The control component includes a mounting base 603 disposed on the lower housing 6 and a circuit board disposed on the mounting base 603. After receiving the detection signal from the detection component 5, the circuit board sends a control signal to the automatic connector device to start the automatic connector operation. The circuit board is not shown in the figure.

[0050] Thus, the overall structure of the yarn breakage sensor 1 is installed, providing a reasonable basis for its use. Since the laser emitting device 501 and the receiving device 502 are installed on both sides of the yarn passage 403, and the yarn passes through the detection area in the yarn passage 403, a relative seal is achieved between the yarn and the detection component 5. This prevents dust and fly shavings generated by friction when the yarn passes through the yarn breakage sensor 1 from interfering with the normal operation of the detection component 5. Furthermore, this invention also includes a dust collection channel to prevent the accumulation of dust and fly shavings, such as... Figure 4-6 The lower housing 6 also includes an n-shaped fastening part 604 integrally connected to the lower housing 6. The n-shaped fastening part 604 covers and fastens to the upper part of the first opening 601. The port of the n-shaped fastening part 604 is perpendicular to the surface of the lower housing 6 and faces the notch 705. Correspondingly, a third opening 404 is also provided on one side wall of the wire passage 403. The third opening 404 cooperates with the port of the n-shaped fastening part 604 and forms a dust collection channel with the n-shaped fastening part 604.

[0051] like Figure 4 , Figure 8 As shown, in order to improve the structural strength of the upper shell 7 and the lower shell 6, the present invention also provides crisscrossing reinforcing ribs 10 on the upper surface of the lower shell 6 and the lower surface of the upper shell 7, respectively.

[0052] Specifically, this invention provides a yarn breakage sensor for a rotor spinning machine. Based on the cooperation of the upper housing 7, lower housing 6, and guide plate 9, the first ceramic yarn feeder, the yarn feed channel 403, and the second ceramic yarn feeder are sequentially pressed together from bottom to top. This eliminates the existing method of using glue for bonding, preventing the yarn breakage sensor 1 from loosening or changing the position of the ceramic yarn feeder 401 due to prolonged use, which would affect the normal operation of the detection component 5. In addition, this invention also installs the laser emitting device 501 and the receiving device 502 in the detection component 5 on both sides of the yarn feed channel 403. The yarn passes through the detection area in the yarn feed channel 403, achieving a relatively sealed separation between the yarn and the detection component 5. In addition, the dust collection channel is set up to avoid the accumulation of dust and fly waste, which would reduce the detection effect of the detection component 5 and prevent the normal operation of the rotor spinning machine from being affected.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
