Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, and in particular to a segmented pressure adjustable linen yarn cleaning device. Background Technology

[0002] In the production of hemp yarn, the cleaning process has a decisive impact on yarn quality and subsequent processing performance. Hemp fibers are inherently coarse and have a high impurity content, requiring precise mechanical action and chemical cleaning to remove impurities such as pectin and lignin. However, traditional cleaning equipment suffers from multiple technical bottlenecks, making it difficult to meet the production requirements of high-quality hemp yarn.

[0003] Existing cleaning equipment generally uses a fixed pressure mode, which cannot adapt to the cleaning needs of different batches and different thicknesses of linen yarns. If the pressure is too high, it can easily lead to fiber breakage and reduced strength, while insufficient pressure will make it difficult to remove deep impurities, resulting in incomplete cleaning. This fixed design of pressure parameters makes the equipment extremely incompatible with various types of linen yarns, and companies often need to configure special equipment for different yarn types, which significantly increases production costs.

[0004] An unreasonable flow path for the cleaning solution is another prominent issue. Traditional equipment often employs open immersion or unidirectional spraying structures, resulting in disordered turbulence of the cleaning solution on the yarn surface. This not only creates cleaning dead zones but also leads to localized accumulation and secondary adhesion of impurities. Although some equipment incorporates a circulation system, the lack of optimized flow channel design results in low circulation efficiency of the cleaning solution, leading to severe mixing of fresh cleaning solution with impurity-laden liquids and significantly reducing cleaning effectiveness. Furthermore, insufficient utilization of the cleaning solution is particularly problematic, resulting in high water consumption per unit yarn, increasing production costs and adding to the burden of subsequent wastewater treatment.

[0005] Furthermore, poor coordination between the washing and dehydration processes is common. Washed yarn carries a large amount of free moisture into the next process, increasing drying energy consumption and potentially causing uneven moisture distribution and variations in yarn shrinkage. These technical deficiencies collectively result in traditional washing equipment being significantly inadequate in terms of washing efficiency, yarn quality assurance, and performance, making it difficult to meet the high-quality, low-energy consumption development needs of the modern hemp textile industry.

[0006] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

Detailed Implementation

[0021] The following is a detailed explanation with reference to the accompanying drawings.

[0022] Example 1

[0023] This utility model provides a segmented pressure-adjustable linen yarn cleaning device, such as... Figure 1 and Figure 2As shown, the system includes a cleaning body 100. The cleaning body 100 is hollow, and an inlet 101 is provided on its side. A feed roller 102 for conveying hemp yarn 300 into the cleaning body 100 is provided at the inlet 101. A pressure application assembly 200 is also provided inside the cleaning body 100. The pressure application assembly 200 includes a drive motor 201 located at the vertical end of the cleaning body 100, a drive rod 202 connected to the output shaft of the drive motor 201, and a pressure roller 203 provided at the end of the drive rod 202 away from the drive motor 201. The vertical end of the pressure roller 203 is semi-circular and fixedly connected to the drive rod 202 by a baffle 204. The baffle 204 has end panels 205 with cylindrical geometry at both horizontal ends. A plurality of guide rollers 206 arranged circumferentially are provided between the opposing end panels 205. This invention achieves multi-dimensional technical advantages by setting up a cleaning body 100, a yarn inlet 101, a yarn feeding wheel 102, and a pressure application component 200. The hollow structure of the cleaning body 100 provides a closed space for cleaning the linen yarn 300, preventing splashing of cleaning fluid and overflow of impurities, and ensuring a clean working environment. The yarn feeding wheel 102 at the yarn inlet 101 can smoothly convey the linen yarn 300 into the cleaning body 100, reducing friction between the yarn and the edge of the yarn inlet 101, and preventing yarn wear or fuzzing. The drive motor 201 in the pressure application component 200 can drive the push rod 202 to move up and down through the output shaft, thereby adjusting the pressure of the pressure wheel 203 on the linen yarn 300, realizing the core function of "segmented pressure adjustment", adapting to the cleaning needs of linen yarn 300 of different thicknesses and materials. The semi-circular structure of the baffle 204 can adapt to the arc-shaped surface of the pressure roller 203, preventing the cleaning liquid from accumulating on the top of the pressure roller 203. The cylindrical end panels 205 on both sides can axially position the guide roller 206, preventing the guide roller 206 from shifting. The guide rollers 206 arranged circumferentially between the opposite end panels 205 can make the linen yarn 300 fit together in an arc shape for conveying, increasing the contact area between the yarn and the cleaning liquid, laying the foundation for subsequent uniform cleaning.

[0024] According to a preferred embodiment, a plurality of guide rollers 206 are located in the space between a baffle 204 and end panels 205 located on both sides of the baffle 204. Both ends of the guide rollers 206 are rotatably connected to the end panels 205. The enclosed space formed by the baffle 204 and the end panels 205 radially limits the guide rollers 206, preventing them from disengaging from their preset positions during rotation and ensuring conveying stability. The rotatable connection between the guide rollers 206 and the end panels 205 converts the sliding friction between the hemp yarn 300 and the guide rollers 206 into rolling friction, significantly reducing yarn conveying resistance, minimizing fiber damage to the yarn surface, improving conveying efficiency, and preventing yarn stretching deformation due to excessive resistance.

[0025] According to a preferred embodiment, a plurality of guide rollers 206 are arranged on the circumference between at least two end panels 205. The guide rollers 206 extend axially and parallel to the line connecting the axes of the at least two end panels 205. The circumferentially arranged guide rollers 206 create an arc-shaped path for the linen yarn 300 during transport, significantly extending the residence time of the yarn within the cleaning body 100 compared to straight-line transport, allowing the linen yarn 300 more time to contact the cleaning solution and improving the impurity removal rate. The axial extension of the guide rollers 206 parallel to the line connecting the axes of the end panels 205 ensures that the rotation direction of all guide rollers 206 is synchronized, preventing the linen yarn 300 from shifting or tangling during transport due to deviations in the extension direction of the guide rollers 206, ensuring accurate yarn transport trajectory, and further improving cleaning uniformity.

[0026] According to a preferred embodiment, a flow channel 207 for the flow of cleaning fluid is defined between adjacent guide rollers 206. The width of the flow channel 207 is greater than or equal to the distance between adjacent guide rollers 206. The flow channel 207 provides a directional flow channel for the cleaning fluid, allowing it to flow precisely through the area where the linen yarn 300 is located, avoiding localized insufficient cleaning fluid caused by disordered flow within the cleaning body 100. The width of the flow channel 207 is not less than the distance between adjacent guide rollers 206, effectively preventing the problem of obstructed cleaning fluid flow caused by an excessively narrow flow channel 207. This ensures that the cleaning fluid continuously and sufficiently contacts the linen yarn 300 through the flow channel 207, and can even penetrate into the internal gaps of the yarn to flush out deeply hidden impurities, thus improving the thoroughness of the cleaning.

[0027] According to a preferred embodiment, a plurality of flow holes 208 are provided on the baffle 204. The flow holes 208 are arranged in a vertically downward orientation. The downward orientation of the flow holes 208 guides the cleaning liquid in the upper part of the cleaning body 100 to flow directionally from top to bottom towards the pressure roller 203 and the linen yarn 300, forming a "spray-like" rinsing effect, enhancing the removal of impurities from the yarn surface, and effectively improving the soaking and cleaning efficiency. The directional flow of the cleaning liquid can avoid the formation of eddies within the cleaning body 100, reducing waste caused by splashing of the cleaning liquid, while ensuring uniform concentration of the cleaning liquid in different areas within the cleaning body 100, and avoiding localized impurity accumulation that affects the cleaning effect.

[0028] According to a preferred embodiment, the side wall of the cleaning body 100 is further provided with an inlet 103 and an outlet 104 for cleaning fluid circulation. The inlet 103 and outlet 104 penetrate the side wall of the cleaning body 100 and connect to a circulating water pump. The inlet 103 is located vertically above the outlet 104, and the line connecting the inlet 103 and outlet 104 passes through the flow channel 207 and the flow hole 208. The inlet 103's vertical position above the outlet 104 and the line passing through the flow channel 207 and flow hole 208 enable the recycling of the cleaning fluid and precise cleaning. The arrangement of the inlet 103 above and the outlet 104 below, in conjunction with the circulating water pump, forms a top-down cleaning fluid circulation flow, continuously discharging the cleaning fluid from the outlet 104 while simultaneously replenishing it from the inlet 103, thus achieving continuous flow of the cleaning fluid. The line connecting the inlet 103 and the outlet 104 passes through the flow channel 207 and the flow hole 208, ensuring that the circulating cleaning liquid can preferentially flow through the area of ​​the linen yarn 300 and the pressure roller 203 at the guide roller 206, so that the yarn is always in the process of flowing circulation, improving cleaning efficiency while reducing the total amount of cleaning liquid used, thus achieving energy saving and consumption reduction.

[0029] According to a preferred embodiment, the cleaning body 100 is further provided with at least two pressure rollers 105 for squeezing the hemp yarn 300 to partially remove the cleaning liquid. The hemp yarn 300 passes sequentially through the feed roller 102 and the guide roller 206 to the pressure rollers 105. The squeezing point of the hemp yarn 300 between the at least two pressure rollers 105 is at the same vertical height as the feed roller 102 conveys the hemp yarn 300. The squeezing action of the pressure rollers 105 on the hemp yarn 300 can quickly remove some of the cleaning liquid adhering to the yarn surface, reducing the energy consumption of the subsequent drying process and lowering the overall production energy consumption. The conveying path of the hemp yarn 300 "feed roller 102-guide roller 206-pressure roller 105" forms a continuous and smooth cleaning-dehydration process, avoiding yarn jamming during process transitions and ensuring production continuity. The yarn compression point between the pressure rollers 105 and the conveying height of the feed rollers 102 are the same, which can ensure that the tension of the linen yarn 300 is stable during the conveying process, avoid excessive stretching of the yarn (causing the yarn to become thinner and its strength to decrease) or loosening (causing the yarn to tangle) caused by the height difference, and effectively protect the physical properties of the linen yarn 300.

[0030] According to a preferred embodiment, a baffle plate 110 is also provided inside the cleaning body 100. The baffle plate 110 divides the interior of the cleaning body 100 into an overflow chamber 106. The vertical height of the baffle plate 110 is higher than the pressure roller 203 but lower than the pressure roller 105. The height design of the baffle plate 105 can precisely control the liquid level of the cleaning liquid inside the cleaning body 100—the liquid level is stably above the pressure roller 203 and below the pressure roller 105, which ensures that the linen yarn 300 at the pressure roller 203 can be completely immersed in the cleaning liquid to ensure the cleaning effect, while preventing the cleaning liquid from contacting the pressure roller 105 (preventing the yarn from reabsorbing water after the pressure roller 105 comes into contact with the cleaning liquid). The overflow chamber 106 separated by the baffle plate 105 can accommodate excess cleaning fluid in the cleaning body 100 (such as cleaning fluid fluctuations during circulation or excess liquid carried in by the yarn), preventing the cleaning fluid from overflowing the cleaning body 100, while also preventing excessive cleaning fluid from flooding the pressure roller 105 or the yarn exit area, ensuring the normal function of each component.

[0031] According to a preferred embodiment, an overflow port 107 is provided at the vertically downward end of the overflow chamber 106. The overflow port 107 is connected to a circulating water pump. The overflow port 107 returns excess cleaning fluid in the overflow chamber 106 to the circulating water pump, allowing this portion of the cleaning fluid to re-enter the "inlet 103-cleaning body 100-outlet 104" circulation system, avoiding waste of cleaning fluid, improving cleaning fluid utilization, and reducing production costs. The overflow port 107 can promptly discharge liquid from the overflow chamber 106, preventing excessive liquid accumulation in the overflow chamber 106 from overflowing the baffle plate 105 and entering the core cleaning area of ​​the cleaning body 100, thus avoiding abnormal fluctuations in the liquid level that could affect the cleaning effect.

[0032] According to a preferred embodiment, a yarn outlet 108 is also provided on the side of the cleaning body 100. A yarn outlet wheel 109 is provided at the yarn outlet 108 for conveying the linen yarn 300 to the outside of the cleaning body 100. The yarn outlet 108 provides a dedicated output channel for the cleaned linen yarn 300, avoiding damage caused by friction with equipment components when the yarn passes through other areas, and ensuring that the yarn output direction is fixed, which facilitates the connection with subsequent processes (such as drying and winding).
