Description

Technical Field

[0001] This utility model relates to the field of textile thread breakage prevention and early warning technology, specifically a textile thread breakage prevention and early warning device for jute textile machines. Background Technology

[0002] Jute is a commonly used material in decoration, including various fabrics such as chemical fiber carpets, non-woven wall coverings, linen, nylon, colored adhesive tape, and flannel. A textile machine, also called a spinning machine, loom, or cotton spinning machine, was a tool used in ancient times to process raw materials such as thread, silk, and hemp into yarn and then weave it into fabric. During the processing of jute yarn, it is necessary to prevent breakage and to detect whether the hemp rope is broken. Therefore, a jute spinning machine yarn breakage prevention and early warning device is provided.

[0003] For example, a jute spinning machine yarn breakage prevention and early warning device with announcement number "CN216445701U" describes a method where cut jute rope is pressed and shaped by a holding wheel, and then enters a water tank through a through-groove. A water outlet pipe humidifies the rope to prevent breakage due to excessive dryness during processing. However, this method only sprays water onto the rope through a water pipe, resulting in minimal contact between the rope and water. Continuous water spraying increases operating costs. Furthermore, it's impossible to determine if the rope is broken before humidification, leading to work interruptions if a break occurs. Therefore, its practicality is limited. Utility Model Content

[0004] The purpose of this invention is to solve the problems of spraying water onto hemp ropes through water pipes, which results in minimal contact between the hemp ropes and water, requires continuous water spraying to humidify the hemp ropes, thus increasing working costs, and makes it impossible to determine whether the hemp ropes are broken before humidifying them, leading to work interruptions and low practicality. Therefore, this invention proposes a yarn breakage prevention and early warning device for jute textile machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A jute spinning machine yarn breakage prevention and early warning device is designed, comprising a base plate and a frame. The upper middle part of the outer wall of the base plate is fixedly connected to the frame. The upper middle part of the inner wall of the frame is provided with a jute spinning yarn breakage early warning structure. A box is fixedly connected to the upper right side of the outer wall of the base plate. The upper right side of the outer wall of the box is provided with a jute spinning yarn breakage prevention structure. Two shells are fixedly connected to the upper end of the inner wall of the frame. The inner wall of the shell is slidably connected to the plate. A second spring is provided at the upper end of the inner wall of the shell. The two ends of the second spring are fixedly connected to the shell and the plate respectively. The lower end of the plate is rotatably connected to a first rotating shaft through a bearing. Two bells are fixedly connected to the upper end of the inner wall of the frame.

[0007] Preferably, the jute yarn breakage early warning structure includes a shell, the upper end of the outer wall of the shell is fixedly connected to a frame, the inner wall of the shell is slidably connected to a horizontal plate, the inner wall of the horizontal plate is slidably connected to two sliding rods, the two ends of the sliding rods are fixedly connected to the shell, the upper end of the outer wall of the horizontal plate is provided with a first spring, the two ends of the first spring are respectively fixedly connected to the shell and the horizontal plate, the lower end of the outer wall of the horizontal plate is fixedly connected to a vertical plate, the outer wall of the vertical plate is slidably connected to the shell, and the lower end of the vertical plate is rotatably connected to a rotating wheel through a bearing.

[0008] Preferably, the lower ends of the outer walls of the two first rotating shafts are in contact with the second rotating shaft, and the second rotating shaft is rotatably connected to the frame through a bearing.

[0009] Preferably, a straight plate is fixedly connected to the upper left side of the base plate, and the upper end of the straight plate is rotatably connected to the first turntable through a bearing. The inner wall of the first turntable is threadedly connected to the second turntable.

[0010] Preferably, the jute yarn anti-breakage structure includes a vertical rod, a first scraper fixedly connected to the lower end of the outer wall of the vertical rod, the lower end of the outer wall of the first scraper abutting against a second scraper, the lower end of the outer wall of the second scraper fixedly connected to the housing, a third spring provided on the outer wall of the vertical rod, the two ends of the third spring being fixedly connected to the housing and the vertical rod respectively, and the inner wall of the housing being rotatably connected to multiple rotating rods through a sealed bearing.

[0011] Preferably, the outer wall of the vertical rod is slidably connected to the housing, and the lower right end of the housing is fixedly connected to the oil drain port.

[0012] This utility model proposes a jute spinning machine thread breakage warning device, the beneficial effects of which are as follows: The jute spinning thread breakage warning structure tightens the winding of the jute spinning thread, pulling the rotating wheel and vertical plate. The vertical plate drives the horizontal plate to slide downwards on the outer wall of the outer casing and slide rod, stretching the first spring. Simultaneously, the horizontal plate moves away from the bell. When the jute rope breaks, the jute spinning thread loosens, releasing the downward pull on the rotating wheel. The first spring pulls the horizontal plate upwards, and the bell rings, alerting the worker to the jute spinning thread breakage. This makes it easier for workers to detect jute spinning thread breakage and take measures to replace the jute spinning thread, reducing work interruption time and thus improving practicality.

[0013] The jute yarn anti-breakage structure works by pulling up a vertical rod to move the first scraper upwards and compress the third spring. The jute yarn can then be placed between the first and second scrapers. Releasing the scrapers pushes the third spring back, causing the first and second scrapers to abut against each other. The first and second scrapers scrape off the large amount of tung oil adhering to the surface of the jute yarn. Multiple rotating rods limit the jute yarn and soak it in tung oil. The first and second scrapers then scrape off the remaining tung oil, effectively increasing the contact area between the jute yarn and the tung oil. Excess tung oil is scraped off and collected, reducing operating costs. Simultaneously, soaking the jute yarn improves its corrosion resistance, heat resistance, and oxidation resistance, thus extending its service life. This process effectively prevents the jute yarn from breaking. Attached Figure Description

[0030] Working principle:

[0031] Early warning system for jute yarn used in textile machines:

[0032] When processing jute yarn is required, hold the first turntable 11 and rotate the second turntable 12 outward to dislodge it. Then, insert the yarn roller wound with jute yarn into the shaft of the first turntable 11, and further limit the jute yarn bobbin by rotating the second turntable 12 inward. Then, remove the end of the jute yarn and process it according to... Figure 2During the line conveying process, the two first turntables 8 can be lifted to compress the second springs 6 and place them inside. The rebound of the second springs 6 pushes the first rotating shaft 8 against the second turntable 9 to limit the jute yarn. At the same time, the vertical rod 201 is pulled upward to move the first scraper 203 upward and compress the third spring 204. Then, the jute yarn can be placed between the first scraper 203 and the second scraper 205. The scraper 203 is released, and the rebound of the third spring 204 pushes the first scraper 203 against the second scraper 205, further securing the end of the jute yarn to the external take-up roller. At the same time, an appropriate amount of tung oil is added to the housing 13. Then, the take-up roller is fixed to the output shaft of the external motor and rotates to take up the jute yarn. Taking up the jute yarn will tighten it and pull the rotating wheel 106 and... The vertical plate 105 drives the horizontal plate 102 to slide downwards on the outer wall of the outer casing 101 and the slide bar 103, stretching the first spring 104. At the same time, the horizontal plate 102 moves away from the bell 4. During the winding of the jute yarn, the first turntable 8, the second turntable 9, and the rotating wheel 106 rotate with it through the bearing. Meanwhile, multiple rotating rods 202 rotate with the jute yarn inside the housing 13 through the sealed bearing. When the jute rope breaks, the jute yarn loosens, releasing the downward pull on the rotating wheel 106. The first spring 104 pulls the horizontal plate 102 upwards, striking the bell and producing a sound. This movement can provide an early warning of jute yarn breakage, effectively reminding workers to take measures. Then, the same operation is performed to replace the jute yarn and proceed with subsequent work.

[0033] Oiling process to prevent breakage of jute yarn on textile machines:

[0034] When the jute spinning thread is immersed in tung oil in the box 13 by multiple rotating rods 202, a large amount of tung oil adhering to the surface of the jute spinning thread is scraped off by the first scraper 203 and the second scraper 205. The scraped tung oil will flow into the box 13. This movement can perform oiling and scraping work on the jute spinning thread. Immersing the jute spinning thread in tung oil effectively improves the anti-corrosion, heat resistance and oxidation resistance of the jute spinning thread, thereby extending the service life of the jute spinning thread. This can be used to prevent the jute spinning thread from breaking. At the same time, the immersion time in tung oil can be determined according to the thickness of the jute spinning thread, and the soaking time can be determined according to the requirements.

[0035] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
