Description

Technical Field

[0001] The utility model relates to the technical field of linen yarn production, in particular to an automatic yarn breakage stop device for linen yarn. Background Technique

[0002] Linen yarn is yarn processed by spinning technology with natural linen fiber as raw material. Among them, the automatic yarn breakage stop device for linen yarn is a high-precision production guarantee device designed according to the characteristics of linen fiber. The stop device usually consists of structures such as a high-sensitivity tension sensor, an intelligent tension compensation mechanism, and a dual-redundancy braking system. The device uses a high-precision photoelectric sensor or pressure sensor to monitor the yarn tension or motion state in real time. After the control system receives the sensor signal, it quickly judges the yarn breakage situation through the built-in algorithm.

[0003] For example, the Chinese patent "An Automatic Yarn Breakage Stop Device for Producing Linen Yarn" with the publication number CN212834248U includes a "square frame" and linen yarn. Inside the "square frame", a first rotating shaft and a second rotating shaft are rotatably connected. Above the inside of the "square frame", two sliding components are provided. Between the two sliding components, a third rotating shaft is rotatably connected; the sliding component includes a fixed block, the fixed block is fixedly installed on an inner wall of the "square frame", above the fixed block, a fixed rod is fixedly installed, the top surface of the fixed rod is fixedly connected to the inner top surface of the "square frame", a slider is slidably sleeved on the outer side of the fixed rod, and a spring is sleeved on the circumferential side of the fixed rod between the fixed block and the slider; a distance sensor is fixedly installed on the inner top surface of the "square frame", a receiving plate is fixedly installed on the upper surface of a slider, the distance sensor is directly above the receiving plate, a controller is fixedly installed on the outside of the "square frame", a buzzer is fixedly installed above the "square frame", the first rotating shaft and the second rotating shaft are respectively located at the two ends of the bottom of the "square frame", and the first rotating shaft and the second rotating shaft are on the same horizontal plane. One end of the first rotating shaft is connected to the inner wall of the "square frame" through a bearing.

[0004] Although the above-mentioned prior art can realize the stop detection of linen yarn, in actual use, on the one hand, the position of the roller is difficult to adjust. Usually, the roller for placing linen yarn is fixedly arranged on the device, resulting in the relaxation of linen yarn, which will affect the result of stop detection. On the other hand, the linen yarn is prone to position deviation. Usually, the linen yarn is wound between multiple rollers, resulting in the deviation of the linen yarn after long-term use, thereby reducing the detection accuracy. Therefore, it does not meet the existing requirements. For this reason, we propose an automatic yarn breakage stop device for linen yarn. Content of the Utility Model

[0005] The purpose of this invention is to provide an automatic yarn breakage stop device for linen yarn, in order to solve the problems mentioned in the background art, such as the difficulty in adjusting the position of the roller and the easy positional deviation of linen yarn.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic yarn breakage stop device for flax yarn, comprising a base, with a first mounting plate provided at both the front and rear ends of one side of the base, and a second mounting plate provided at both the front and rear ends of the other side of the base, the second mounting plate and the first mounting plate being symmetrically arranged, a second fixing rod provided between the first mounting plate and the second mounting plate, the front and rear ends of the second fixing rod being rotatably connected to the first mounting plate and the second mounting plate, a second roller being fixedly provided on the outside of the second fixing rod, and a first hydraulic telescopic device being fixedly provided at the lower end of both the first mounting plate and the second mounting plate, the lower end of the first hydraulic telescopic device being fixedly connected to the base.

[0007] Preferably, a second hydraulic telescopic device is fixedly provided on both sides of the outside of the first mounting plate and the second mounting plate, and the telescopic end of the second hydraulic telescopic device extends to the other side of the first mounting plate and the second mounting plate.

[0008] Preferably, a limit ring is fixedly provided on one side of the telescopic end of the second hydraulic telescopic device. The limit ring is sleeved on the outside of the second roller, and the limit ring and the second roller are in sliding cooperation.

[0009] Preferably, a fixing frame is fixedly installed at the center of the upper end of the base, an mounting ear plate is installed below the fixing frame, a negative pressure adsorption plate is installed above the inside of the mounting ear plate, and a telescopic tube is fixedly installed at the upper end of the negative pressure adsorption plate. The upper end of the telescopic tube passes through the mounting ear plate and extends to the lower end of the fixing frame.

[0010] Preferably, an air extraction pipe is fixedly installed at the center of the upper end of the fixed frame, and the lower end of the air extraction pipe is connected to the telescopic pipe.

[0011] Preferably, tension sensors are fixedly installed at both the front and rear ends of the upper end of the mounting ear plate, the upper end of the tension sensor is fixedly connected to the fixing frame, and warning lights are fixedly installed at both the front and rear ends of the upper end of the fixing frame, and the warning lights are electrically connected to the tension sensors.

[0012] Preferably, a first roller is provided at the center of the lower part of the mounting ear plate, and a first fixing rod is fixedly provided at both the front and rear ends of the first roller, with the other end of the first fixing rod rotatably connected to the mounting ear plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The tension of the flax yarn can be adjusted by the first mounting plate and the second mounting plate. When the flax yarn is being produced, the installation of the flax yarn is completed. Then, the tension of the flax yarn is adjusted according to the winding state of the flax yarn. At this time, the first hydraulic telescopic device is opened simultaneously, so that the telescopic end of the first hydraulic telescopic device retracts. The retraction of the telescopic end of the first hydraulic telescopic device drives the first mounting plate and the second mounting plate to move downward together. At the same time, the position of the flax yarn on the first roller remains unchanged until the flax yarn is adjusted to a taut state, so as to avoid false alarms due to the loosening of the flax yarn, thereby improving the effect of yarn breakage detection.

[0015] (2) This utility model can limit the flax yarn by means of the second hydraulic telescopic device and the limiting ring. Before the production of flax yarn, the spacing of the limiting ring is adjusted according to the size of the flax yarn. At this time, the second hydraulic telescopic device is opened at the same time, so that the telescopic end of the second hydraulic telescopic device extends. The extension of the telescopic end of the second hydraulic telescopic device drives the limiting ring to move towards each other outside the second roller until the limiting ring is adjusted to a suitable position. Then the flax yarn is wound on the first roller and the second roller, and the flax yarn is between the limiting rings. Subsequent operations are then performed, thereby improving the accuracy of the yarn breakage detection.

[0016] (3) This utility model can treat the floating hair on the surface of flax yarn by using a negative pressure adsorption plate and an air extraction pipe. When flax yarn is produced, the flax yarn has passed through the first roller and the second roller. At this time, the external air pump is turned on, and the air near the negative pressure adsorption plate is extracted through the external air pump and the telescopic pipe, so that the air enters the negative pressure adsorption plate at an accelerated speed. At this time, the floating hair on the flax yarn will enter the negative pressure adsorption plate along with the air. The concentrated floating hair is uniformly treated after the flax yarn production is completed, so as to prevent the floating hair on the flax yarn from falling to the connection between the second fixed rod and the mounting ear plate, thereby improving the smoothness of the rotation of the second fixed rod.

[0024] Please see Figure 1 and Figure 2 A second fixing rod 16 is provided between the first mounting plate 12 and the second mounting plate 13. The front and rear ends of the second fixing rod 16 are rotatably connected to the first mounting plate 12 and the second mounting plate 13. A second roller 17 is fixedly provided on the outside of the second fixing rod 16. A first hydraulic telescopic device 11 is fixedly provided at the lower end of the first mounting plate 12 and the second mounting plate 13. The lower end of the first hydraulic telescopic device 11 is fixedly connected to the base 1, so as to facilitate the adjustment of the tension of the flax yarn through the first hydraulic telescopic device 11.

[0025] Please see Figure 1 and Figure 4 A second hydraulic telescopic device 14 is fixedly installed on both sides of the outside of the first mounting plate 12 and the second mounting plate 13. The telescopic end of the second hydraulic telescopic device 14 extends to the other side of the first mounting plate 12 and the second mounting plate 13. A limit ring 15 is fixedly installed on one side of the telescopic end of the second hydraulic telescopic device 14. The limit ring 15 is sleeved on the outside of the second roller 17, and the limit ring 15 and the second roller 17 slide together to facilitate the limiting of the flax yarn through the limit ring 15.

[0026] Please see Figure 1 , Figure 2 and Figure 3 A fixing frame 2 is fixedly installed at the center of the upper end of the base 1. A mounting ear plate 3 is installed below the fixing frame 2. A negative pressure adsorption plate 10 is installed inside the upper part of the mounting ear plate 3. A telescopic tube 9 is fixedly installed at the upper end of the negative pressure adsorption plate 10.

[0027] Working principle: In use, first adjust the spacing of the limiting rings 15 according to the size of the flax yarn. At the same time, simultaneously activate the second hydraulic telescopic device 14, causing its telescopic end to extend. The extension of the telescopic end of the second hydraulic telescopic device 14 drives the limiting rings 15 to move towards each other outside the second roller 17 until the limiting rings 15 are adjusted to the appropriate position. Then, wind the flax yarn onto the first roller 6 and the second roller 17, with the flax yarn positioned between the limiting rings 15. Adjust the tension according to the winding state of the flax yarn. At the same time, simultaneously activate the first hydraulic telescopic device 11, causing its telescopic end to extend. The process involves shrinking the fabric by retracting the telescopic end of the first hydraulic telescopic device 11, which in turn moves the first mounting plate 12 and the second mounting plate 13 downwards together. Meanwhile, the position of the flax yarn on the first roller 6 remains unchanged until the flax yarn is adjusted to a taut state. When producing flax yarn, the flax yarn has already passed through the first roller 6 and the second roller 17. At this time, the external air pump is turned on, and the air near the negative pressure adsorption plate 10 is drawn through the external air pump and the telescopic pipe 9, so that the air is accelerated into the negative pressure adsorption plate 10. At this time, the loose fibers on the flax yarn will be carried into the negative pressure adsorption plate 10 along with the air. The collected loose fibers are uniformly processed after the flax yarn production is completed.
