Description

Technical Field

[0001] This utility model relates to the field of textile thread production technology, and in particular to a textile thread lubrication device. Background Technology

[0002] In the textile production process, lubrication is necessary to prevent thread tangling and equipment malfunctions. Currently, most common lubrication methods involve directly immersing the thread in lubricant using rollers. However, this often results in the thread carrying excessive lubricant with it when pulled out, leading to waste and potential dripping onto the equipment. While some existing equipment includes scraping devices to remove excess lubricant, incomplete removal is common due to the large volume of lubricant adhering to the thread. Therefore, a suitable textile thread lubrication device is urgently needed to address these problems. Utility Model Content

[0003] The purpose of this invention is to provide a textile thread lubrication device to solve the problems existing in the prior art, and to effectively control the amount of lubricant soaking into the textile thread, thereby reducing the waste of lubricant.

[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a textile yarn lubrication device, including a fixing frame for fixing to the yarn outlet end of a textile equipment, and further including: The lubrication box is fixed to the bracket and its inner cavity contains lubricating fluid. A pair of guide rollers are rotatably connected to opposite sides of the top of the lubrication box, and the pair of guide rollers are distributed sequentially along the yarn exit direction, with the bottom end of the guide rollers used for rolling contact with the yarn. A lubricating roller is rotatably connected inside the lubricating box and located between a pair of guide rollers. The bottom of the pair of guide rollers is at a lower level than the top of the lubricating roller. The top of the lubricating roller is used for sliding contact with the textile thread, and the bottom of the lubricating roller is immersed in lubricating fluid. A driving component is disposed on the lubrication box. The driving end of the driving component is connected to the lubrication roller so that the lubrication roller rotates in the opposite direction to the exit speed of the textile thread, and the rotation speed of the lubrication roller is greater than the exit speed of the textile thread.

[0005] Preferred options also include: The first scraper is fixed inside the lubrication box by a crossbar, and the first scraper is located at the front end of the lubrication roller where it contacts the textile thread. One end of the first scraper extends along the direction of the lubrication roller, and a gap is provided between the first scraper and the lubrication roller.

[0006] Preferably, a bracket is fixedly connected to the top of the lubrication box near the outlet end, and the bracket is arranged between the adjacent guide roller and lubrication roller. A second scraper is fixedly connected to the top and bottom surface of the bracket, and the bottom end of the second scraper is in sliding contact with the textile thread.

[0007] Preferably, the second scraper is a ceramic plate, and the bottom end of the second scraper has an arc-shaped structure.

[0008] Preferably, the bottom horizontal height of the second scraper is higher than the bottom horizontal height of the guide roller and lower than the top horizontal height of the moistening roller.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figures 1-5 This utility model provides a textile yarn lubrication device, including a fixing frame 1 for fixing to the yarn outlet end of a textile equipment, and further including: Lubrication box 2 is fixedly connected to the fixing frame 1, and its inner cavity is filled with lubricating fluid; A pair of guide rollers 3 are rotatably connected to opposite sides of the top of the lubrication box 2, and the pair of guide rollers 3 are distributed sequentially along the direction of the yarn exit. The bottom end of the guide rollers 3 is used to make rolling contact with the yarn. The lubricating roller 4 is rotatably connected inside the lubricating box 2 and located between a pair of guide rollers 3. The bottom of the pair of guide rollers 3 is at a lower horizontal height than the top of the lubricating roller 4. The top of the lubricating roller 4 is used for sliding contact with the textile thread, and the bottom of the lubricating roller 4 is immersed in lubricating fluid. A driving component is installed on the lubrication box 2. The driving end of the driving component is connected to the lubrication roller 4 so that the lubrication roller 4 rotates in the opposite direction to the exit of the textile thread, and the rotation speed of the lubrication roller 4 is greater than the exit speed of the textile thread.

[0018] In this invention, a lubricating box 2 holds lubricating fluid, and a pair of guide rollers 3 guide the yarn out of the machine, causing the yarn to slide into contact with the bottom of the guide rollers 3. The bottom of the guide rollers 3 is lower than the top of the lubricating roller 4, allowing the guide rollers 3 to squeeze the yarn and make it slide into contact with the top of the lubricating roller 4. A drive unit drives the lubricating roller 4 to rotate in the opposite direction. During the rotation of the lubricating roller 4, the lubricating fluid in the lubricating box 2 is adaptively adhered to the surface of the lubricating roller 4. Then, as the lubricating roller 4 rotates, the lubricating fluid is applied to the yarn. Compared with the prior art, which directly puts the yarn into the lubricating fluid, this invention can effectively reduce the amount of lubricating fluid adhering, reduce lubricating fluid waste, and achieve control over the amount of lubricating fluid wetting the yarn.

[0019] Specifically, two pairs of fixing plates 5 are integrally formed and fixed on both sides of the lubrication box 2, and the two ends of any guide roller 3 are rotatably connected to the adjacent pair of fixing plates 5.

[0020] Furthermore, it also includes: The first scraper 6 is fixed inside the lubrication box 2 by a crossbar 7, and the first scraper 6 is located at the front end of the lubrication roller 4 where it rolls into contact with the textile thread. One end of the first scraper 6 extends along the direction of the lubrication roller 4, and there is a gap between the first scraper 6 and the lubrication roller 4.

[0021] Specifically, the first scraper 6 is fixed inside the lubrication box 2 by the crossbar 7, and the lubrication roller 4 passes through the first scraper 6 after rotating and adhering to the lubricating liquid. The distance between the first scraper 6 and the lubrication roller 4 is set to effectively control the amount of lubricating liquid adhering and reduce the waste of lubricating liquid.

[0022] In this technical solution, the first scraper 6 has an adjustable width, and the distance between the first scraper 6 and the lubricating roller 4 is based on the diameter of the textile thread. By replacing the first scraper 6 with different widths, the distance can be controlled to the sum of 1-2 textile thread diameters.

[0023] Furthermore, a bracket 8 is fixedly connected to the top of the lubrication box 2 near the outlet end, and the bracket 8 is arranged between the adjacent guide roller 3 and lubrication roller 4. A second scraper 9 is fixedly connected to the top and bottom surfaces of the bracket 8, and the bottom end of the second scraper 9 slides in contact with the textile thread.

[0024] The second scraper 9 is fixed to the bracket 8. The second scraper 9 slides into contact with the textile thread to scrape off a small amount of excess lubricant from the textile thread. Compared with the prior art, by controlling the amount of lubricant adhering to the textile thread and combining it with the scraping of the textile thread by the second scraper 9, the textile thread is effectively wetted and the waste of lubricant can be reduced.

[0025] Furthermore, the second scraper 9 is a ceramic plate, and the bottom end of the second scraper 9 has an arc-shaped structure.

[0026] With an arc-shaped bottom, the second scraper 9 slides against the textile thread, scraping off the attached lubricant and concentrating it along the arc surface to the bottom of the second scraper 9 before finally dripping back into the lubrication box 2.

[0027] Furthermore, the bottom horizontal height of the second scraper 9 is higher than the bottom horizontal height of the guide roller 3 but lower than the top horizontal height of the moistening roller 4. This ensures effective sliding contact between the bottom of the second scraper 9 and the textile thread, and enables the guide roller 3 to effectively contact the textile thread to provide guidance.

[0028] Furthermore, the lubricating roller 4 has symmetrical arc-shaped grooves along the center to both sides.

[0029] The textile thread is guided by an arc-shaped groove. As the lubricating roller 4 rotates and comes into contact with the textile thread, the textile thread is limited to the middle of the lubricating roller 4 to ensure stability. Specifically, the guide roller 3 also adopts an hourglass-shaped structure that is narrow in the middle and wide on both sides to ensure stable delivery of the textile thread.

[0030] Furthermore, the driving component includes a micro geared motor 10, which is fixedly connected to one side of the outer wall of the lubrication box 2. The output shaft of the micro geared motor 10 extends into the lubrication box 2 and is coaxially fixedly connected to the lubrication roller 4.

[0031] In this technical solution, a common miniature DC current geared motor is used, so that the miniature geared motor 10 has a selectable rotation speed. In actual use, the miniature geared motor 10 with a rotation speed slightly faster than the yarn exit speed is selected according to the yarn exit speed, so that the lubricating roller 4 can be fully immersed in the lubricant before contacting the yarn, preventing the situation where the yarn speed is too fast, resulting in some areas of the lubricating roller 4 lacking lubricant.

[0032] Furthermore, a replenishment pipe 11 is connected to one side of the bottom of the lubrication box 2. The replenishment pipe 11 is fixed to the fixing frame 1, and the end of the replenishment pipe 11 away from the fixing frame 1 is used to connect to the lubricating fluid delivery pipe.

[0033] By extending the replenishment pipe 11 away from the fixed frame 1, the replenishment pipes 11 on several textile lubrication devices can be connected to a main lubricating fluid delivery pipeline to perform batch lubrication operations on a large number of textile threads during the textile production process. Specifically, the lubricating fluid level in the lubrication box 2 is higher than the bottom end of the lubrication roller 4 and lower than the bottom end of the first scraper 6.

[0034] This utility model provides a working principle for a textile thread lubrication device: The fixing frame 1 is fixed to the output end of the textile equipment by a support frame or connecting rod (not shown in the figure), and the textile thread passes through the bottom end of a pair of guide rollers 3 in sequence. The textile thread is wound up by a heater and a winding device. The above is the prior art and will not be described in detail. After being guided by the pair of guide rollers 3, the middle of the textile thread slides into contact with the top of the lubricating roller 4. The micro geared motor 10 drives the lubricating roller 4 to rotate, adhering the lubricant in the lubricating box 2. The first scraper 6 scrapes off the excess lubricant, and the lubricant is applied to the textile thread by the lubricating roller 4, thereby controlling the amount of lubricant adhering. Then the textile thread passes through the scraping action of the second scraper 9, at which time the excess lubricant is scraped off again, which can improve the effect of reducing lubricant waste. Finally, the lubricated textile thread is pulled out from the guide roller 3.
