Description

Technical Field

[0001] This utility model relates to the field of cotton scraping equipment, and in particular to a cotton scraping device for a drawing frame. Background Technology

[0002] The drawing frame is a key piece of equipment in the cotton spinning industry. Its main function is to improve the internal structure of the sliver, increase the uniformity of long segments, reduce weight unevenness, straighten and parallel the fibers in the sliver, reduce hooks, and at the same time, mix different types or qualities of raw materials evenly to achieve the specified mixing ratio. After drawing, waste cotton on the surface of the quilt needs to be scraped off to improve the quality of the quilt.

[0003] Currently, traditional cotton scraping equipment typically uses two scraping rollers to scrape the cotton from the quilt. This method has several drawbacks: the distance between the scraping rollers is fixed and cannot be flexibly adjusted according to the actual thickness of the quilt, making it difficult to achieve the desired scraping effect when processing quilts of different thicknesses. At the same time, due to the lack of an effective guiding and constraint mechanism during the quilt conveying process, the quilt is prone to deviation and misalignment. Once the quilt deviates from the predetermined conveying track, the scraping rollers cannot completely cover the quilt surface, resulting in a large number of blind spots in the scraping operation. The problem of incomplete scraping occurs frequently, seriously affecting the quality and stability of the finished quilt. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a cotton scraping device for a drawing frame, which aims to improve the problems in the prior art that the spacing between the cotton scraping rollers cannot be adjusted according to the thickness of the cotton quilt, the cotton quilt cannot be constrained during conveying, and the cotton scraping rollers cannot be automatically cleaned in a timely manner.

An electric push rod is also set, which pushes the clamping plate two at its output end to move. The clamping plate two will then drive the connecting rod connected to it to move. The movement of the connecting rod will drive the rotating rod to rotate, and the rotation of the rotating rod will drive another connecting rod to move, thereby driving the other clamping plate two to move. When the clamping plate two moves, it will drive the clamping plate one to move through the connecting block, thereby restricting the quilt and preventing it from "running off course" and preventing the first and second scraping rollers from not fully covering the quilt, thus preventing incomplete scraping.

When it is necessary to scrape off the waste cotton attached to the first and second scraper rollers, the scraper is moved to the positions of the first and second scraper rollers respectively. Then, the waste cotton is scraped off by the rotation of the first and second scraper rollers. At the same time, the fan is started, and the scraped waste cotton is sucked into the collection frame in the outer shell, thereby completing the collection of waste cotton and preventing the scraped waste cotton from floating around randomly.

[0033] 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.

[0034] Reference Figures 1-5 The present invention provides an embodiment of a cotton scraping device for a drawing frame, comprising a support 1, a support plate 5 fixedly connected to the inner side of the support 1, a limit component provided on the top of the support 1, and a cleaning component provided on the top of the support plate 5.

[0035] The limiting assembly includes two brackets 12 fixedly connected to the top of the support 1. Two limiting rods 13 are fixedly connected to the top of each bracket 12. A fixing plate 14 is fixedly connected to the outer periphery of the two adjacent limiting rods 13. The limiting rods 13 are used to fix the fixing plate 14. A handle bolt 15 is threadedly connected to the middle of one of the fixing plates 14. A slider 11 is slidably connected to the middle of each of the two brackets 12. The top of one slider 11 is fixedly connected to the bottom of the handle bolt 15. Rotating the handle bolt 15 causes the slider 11 to slide, which in turn causes the cotton scraping roller 9 to move up and down, thereby adjusting the distance between the cotton scraping roller 8 and the cotton scraping roller 9 according to the thickness of the quilt. Two electric push rods 22 are fixedly connected inside the support 1. Two clamping plates 21 are slidably connected inside the support 1. The output ends of the two electric push rods 22... Both clamping plates are fixedly connected to the outer wall of one of the clamping plates 21. A connecting block 20 is fixedly connected to the top of each clamping plate 21. A clamping plate 7 is fixedly connected to the top of each connecting block 20. A connecting rod 24 is rotatably connected to the middle of each clamping plate 21. A rotating rod 23 is rotatably connected between the two connecting rods 24. The rotating rod 23 is rotatably connected inside the support 1. By driving the electric push rod 22, one of the clamping plates 21 is pushed to move. The movement of the clamping plate 21 will drive the connecting rod 24 connected to it to move, thereby driving the rotating rod 23 to rotate inside the support 1. When the rotating rod 23 rotates, it will drive the other connecting rod 24 to move, thereby driving the clamping plate 21 on the other side to move. At this time, the connecting block 20 can drive the two clamping plates 7 to move in opposite directions, thereby restricting the quilt and preventing it from "running crooked" when scraping the cotton, which would affect the scraping effect.

[0036] Reference Figure 4 and Figure 6 The cleaning component includes a housing 6 fixedly connected to the top of the support plate 5. Multiple fans 18 are fixedly connected to the outer wall of the housing 6. A collection frame 19 is slidably connected inside the housing 6. Multiple pipes 25 are fixedly connected to the top of the housing 6. Two cylinders 3 are fixedly connected to the top of the support 1. A connecting plate 2 is fixedly connected to the output end of the two cylinders 3. A scraper 17 is fixedly connected to the bottom of the connecting plate 2. A cotton scraping component is provided on the top of the support 1. The waste cotton is scraped off by the scraper 17. The scraped waste cotton is sucked into the pipe 25 by the fans 18 and then falls into the collection frame 19 in the housing 6.

[0037] Reference Figures 1-3The cotton scraping assembly includes a first scraping roller 8 and a second scraping roller 9. The first scraping roller 8 is rotatably connected between two supports 12, and the second scraping roller 9 is rotatably connected between two sliders 11. A first motor 4 is fixedly connected to the outer wall of one of the supports 12, and the output end of the first motor 4 is fixedly connected to one end of the first scraping roller 8. A second motor 10 is fixedly connected to the outer wall of one of the sliders 11, and the output end of the second motor 10 is fixedly connected to one end of the second scraping roller 9. The first motor 4 and the second motor 10 drive the first scraping roller 8 and the second scraping roller 9 to rotate in opposite directions, thereby achieving the effect of scraping cotton while conveying the quilt.

[0038] Reference Figure 1 , Figure 3 and Figure 4 Both the first scraper roller 8 and the second scraper roller 9 are in contact with the scraper 17. The first scraper roller 8 is located directly below the second scraper roller 9. The scraper 17 is used to scrape off the waste cotton on the first scraper roller 8 and the second scraper roller 9.

[0039] Reference Figure 1 and Figure 5 The connecting block 20 is slidably connected to the inside of the support 1, and the clamping plate 7 is slidably connected to the top of the support 1. The connecting block 20 slides to drive the clamping plate 7 to slide on the top of the support 1.

[0040] Reference Figure 4 and Figure 6 The support 1 has multiple notches 26 at the top, which are located directly above the pipe 25. The top of the pipe 25 is fixedly connected to the bottom of the support 1. The scraped waste cotton will be sucked into the pipe 25 through the notches 26.

[0041] Reference Figure 6 The outer casing 6 has two slide rails 27 fixedly connected inside. The collection frame 19 is slidably connected to the top of the two slide rails 27. The collection frame 19 and the slide rails 27 are interference fit. When the device is working, the collection frame 19 needs to use external force to detach from the outer casing 6, so it can remain stable when the collection frame 19 is not subjected to external force.

[0042] Reference Figure 1 and Figure 3 One of the sliders 11 is fixedly connected to a limiting rod 16 at its top. The limiting rod 16 is slidably connected to the middle of the fixed plate 14 on its outer periphery. When the limiting rod 16 is driven to slide, it will slide in the middle of the fixed plate 14.

[0043] Working principle: When it is necessary to adjust the gap between the first scraper roller 8 and the second scraper roller 9, turn the handle bolt 15 to drive the slider 11 to slide in the middle of the bracket 12, thereby moving the second scraper roller 9 upward. At this time, the gap between the first scraper roller 8 and the second scraper roller 9 can be adjusted according to the different thicknesses of the quilt. Since the quilt may "run off course" when it is conveyed to the position of the first scraper roller 8 and the second scraper roller 9, it is necessary to restrict the conveying of the quilt to prevent it from running off course. Start the electric push rod 22, which will drive the second clamping plate 21 to move. When the second clamping plate 21 moves, it will drive the connecting rod 24 connected to it to move. The rotation of the connecting rod 24 will drive the rotating rod 23 to rotate, thereby driving the other connecting rod 24 to move, and then driving the other clamping plate 21 to move. When the second clamping plate 21 moves, it will drive the first clamping plate 7 to move through the connecting block 20, thereby achieving the effect of restricting the quilt.

[0044] When the first scraper roller 8 and the second scraper roller 9 work for a long time, some waste cotton will accumulate on them. Too much waste cotton will affect the scraping effect of the first scraper roller 8 and the second scraper roller 9, so it is necessary to clean the waste cotton in time. At this time, the cylinder 3 drives the connecting plate 2 to move downward, and then drives the scraper 17 to move downward to the position of the first scraper roller 8 and the second scraper roller 9 respectively. At this time, the first scraper roller 8 and the second scraper roller 9 are driven to rotate, and the waste cotton on the first scraper roller 8 and the second scraper roller 9 can be scraped off by the scraper 17. At the same time, the fan 18 is started, and the fan 18 will suck the waste cotton into the collection frame 19 in the outer shell 6 through the notch 26, thereby achieving the effect of collecting waste cotton and preventing the waste cotton from scattering randomly.

[0045] 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.
