Description

Technical Field

[0001] This invention relates to the field of carding machines, and more specifically, to a carding machine self-adjusting leveling control device. Background Technology

[0002] A carding machine is a piece of equipment in the textile industry that combs, cleans, loosens, and homogenizes cotton or other fiber raw materials. Its purpose is to improve fiber quality and provide higher-quality textile raw materials for subsequent spinning processes. In cotton processing, the carding machine not only removes impurities but also ensures uniform fiber distribution through leveling technology, thereby improving the performance of textile products. The main function of self-regulating leveling control equipment is to automatically adjust the working state of the carding machine through an automated system, ensuring fiber uniformity and consistency. Traditional carding machines may require manual adjustment, while modern self-regulating leveling control equipment can automatically adjust various machine parameters, such as fiber density and carding speed, according to actual needs.

[0003] In existing technologies, a large amount of cotton is usually placed on a conveyor device, which then transports the cotton layer into the carding machine. However, during the process of transporting the cotton layer into the carding machine, most of the cotton is first placed on the conveyor device, and the operation of the conveyor device is used to transport the cotton layer into the carding machine. However, during this transport process, it is difficult to ensure the flatness of the cotton layer, resulting in an uneven surface. This leads to differences in the thickness of different areas of the cotton layer, with some areas having relatively thicker cotton layers. This situation may have a certain impact on the carding effect of the subsequent carding machine, such as causing uneven carding. Summary of the Invention

[0004] To solve the above-mentioned technical problems, a self-adjusting leveling control device for a carding machine is provided. This technical solution addresses the issue raised in the background technology, where, during the process of conveying the cotton layer into the carding machine, most of the cotton is first placed on a conveying device, and the operation of the conveying device is used to convey the cotton layer into the carding machine. However, during this conveying process, the flatness of the cotton layer is difficult to guarantee, resulting in an uneven surface. Consequently, the thickness of the cotton layer varies in different areas, with some areas having a relatively thicker cotton layer. This situation may have a certain impact on the carding effect of the subsequent carding machine, such as causing uneven carding.

[0006] Preferably, the cotton pressing assembly includes a fixed cover plate and a sliding plate. Both ends of the fixed cover plate are fixedly connected to sliding blocks. The two sliding blocks are slidably connected inside the sliding plate. The interior of the two sliding plates is provided with telescopic guide posts. The lower ends of the two sliding plates are fixedly installed on the upper end of the conveying assembly near both sides. The interior of the sliding plates is provided with sliding grooves.

[0007] Preferably, a cotton pressing roller is rotatably sleeved on both sides of the lower end of the fixed cover plate, and a telescopic guide post is fixedly installed on the upper end of the fixed cover plate. The telescopic guide post is sleeved inside one of the sliding plates, and a telescopic hydraulic cylinder is telescopically connected to the upper end of the telescopic guide post. The lower end of the telescopic hydraulic cylinder is fixedly installed on the upper end of one of the sliding plates.

[0008] Preferably, the leveling component includes fixed brackets, one end of each of the two fixed brackets is fixedly installed at the upper end of one end of the carding machine mechanism, and a frame is fixedly installed on one side of each of the two fixed brackets opposite to each other. The inner wall of each frame is provided with a through opening, and a first fixed plate and a second fixed plate are fixedly installed at the top of the frame near both ends, respectively.

[0009] Preferably, a sliding rod is fixedly sleeved inside the opposing sides of the first fixed plate and the second fixed plate, and a first movable frame and a second movable frame are slidably sleeved on the outer side of the sliding rod near both ends, and a connecting rod is fixedly installed at the lower end of the first movable frame and the second movable frame.

[0010] Preferably, the lower end of the connecting rod is fixedly installed with a first moving rod and a second moving rod, and the connecting rod is slidably sleeved inside the opening.

[0011] Preferably, the lower ends of both the first and second moving rods are fixedly connected to a leveling scraper.

[0012] Preferably, a mounting bracket is fixedly installed at the upper end of the frame near the center, a connecting plate is fixedly installed at the upper end of the mounting bracket, a servo motor is fixedly installed at the upper end of the connecting plate, the output shaft of the servo motor is sleeved inside the connecting plate, and the output shaft of the servo motor is fixedly connected to the rotating rod.

[0013] Preferably, a gear is fixedly connected to the lower end of the rotating rod, and a first spur gear and a second spur gear are respectively meshed on the outer side of the gear. One end of the first spur gear is fixedly installed at the lower end of the upper end of the first movable frame, and one end of the second spur gear is fixedly installed at the lower end of the upper end of the second movable frame.

[0014] Compared with the prior art, the present invention provides a self-regulating leveling control device for a carding machine, which has the following beneficial effects: (1) The present invention can continuously comb the surface of the cotton layer by adjusting the reciprocating movement of the scraper, flattening the locally accumulated cotton, avoiding thickness differences caused by uneven material distribution. Through the reciprocating movement of the scraper, the uneven dispersion problem on both sides of the cotton layer can be effectively dealt with, ensuring that the thickness of the cotton layer is consistent from the center to the edge, avoiding the phenomenon of uneven surface of the cotton layer, thus causing the thickness of different areas of the cotton layer to be different, preventing the cotton layer in some areas from being relatively thick, and avoiding the combing effect of the subsequent combing machine, such as causing uneven combing.

[0015] (2) The present invention drives the first straight toothed rod and the second straight toothed rod to move relative to each other through gears, thereby achieving synchronous reverse sliding of the first moving rod and the second moving rod. This allows multiple equalizing scraping blocks to move in a "comb-like" staggered pattern on the surface of the cotton layer, which can more comprehensively cover the width direction of the cotton layer and effectively eliminate cotton layer accumulation in the edge area.

[0016] (3) The present invention continuously presses down on the cotton material after the cotton pressing roller contacts the cotton material, which can evenly compact areas with uneven thickness, such as protrusions or loose parts, so as to initially improve the flatness of the cotton layer surface. This allows the cotton pressing roller to adjust the pressing distance according to the actual thickness of the cotton material, avoiding uneven compaction caused by thickness differences.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0020] Please refer to Figure 1 and Figure 2 As shown, a carding machine self-adjusting and leveling control device includes a carding machine mechanism 1. One end of the inner wall of the carding machine mechanism 1 is rotatably fitted with an infeed roller 6. One end of the carding machine mechanism 1 is provided with a conveying component 3 for conveying cotton layers. The lower end of the conveying component 3 is fixedly connected with a support leg 2. The upper end of the conveying component 3 is provided with a pressing component 4 for adjusting the thickness of the cotton layer. The upper end of the conveying component 3 is provided with a leveling component 5 for dispersing and leveling both sides of the cotton layer.

[0021] In a specific embodiment, when the cotton layer needs to be combed, the cotton layer is placed on the conveying component 3, the conveying component 3 starts to operate, and conveys the cotton layer towards the carding machine mechanism 1. The pressing component 4 is set at the upper end of the conveying component 3, and its main function is to initially adjust the thickness of the cotton layer. When the cotton layer passes under the pressing component 4, the pressing component 4 applies downward pressure to the thicker areas of the cotton layer through its own pressure. Under the pressure, the cotton fibers in the thicker areas are squeezed, making the thickness of the cotton layer tend to be uniform. The leveling component 5 is also located at the top of the conveying component 3. It mainly deals with the uneven distribution on both sides of the cotton layer. During the cotton layer conveying process, if the fiber distribution on both sides of the cotton layer is uneven, and the cotton fibers in some areas are loose or piled up, the leveling component 5 will use a specific mechanical structure to move the fibers on both sides of the cotton layer as the cotton layer passes by. When the cotton layer reaches the position of the winding roller 6, the winding roller 6 rotates and winds the cotton layer into the subsequent carding components inside the carding machine mechanism 1. Inside the carding machine mechanism 1, the cotton layer will undergo a series of complex carding processes such as opening, carding, and impurity removal, and finally be made into cotton sliver that meets the requirements. The carding machine opens, cards, removes impurities and mixes the fiber raw materials through mechanical action, and finally processes the fibers into a single-fiber cotton web or cotton sliver. Its core lies in using high-speed rotating carding elements (such as licker-in rollers, cylinders, doffers, etc.) to repeatedly card the fibers and remove impurities at the same time.

[0022] Please refer to Figure 1 , Figure 3 and Figure 4 As shown, the cotton pressing assembly 4 includes a fixed cover plate 41 and a sliding plate 42. Both ends of the fixed cover plate 41 are fixedly connected to sliding blocks 47. The two sliding blocks 47 are slidably connected inside the sliding plate 42. The interior of the two sliding plates 42 is provided with telescopic guide posts 45. The lower ends of the two sliding plates 42 are fixedly installed on the upper end of the conveying assembly 3 near both sides. The lower end of the fixed cover plate 41 near both sides is rotatably fitted with cotton pressing rollers 46. The upper end of the fixed cover plate 41 is fixedly installed with telescopic guide posts 45. The interior of the sliding plates 42 is provided with sliding grooves 43. The telescopic guide posts 45 are fitted inside one of the sliding plates 42. The upper end of the telescopic guide posts 45 is telescopically connected to a telescopic hydraulic cylinder 44. The lower end of the telescopic hydraulic cylinder 44 is fixedly installed on the upper end of one of the sliding plates 42.

[0023] In a specific embodiment, when the conveying component 3 is stationary or operating at low speed, the cotton material is placed or conveyed above the conveying component 3, directly below the two pressing rollers 46. The telescopic hydraulic cylinder 44 is in its initial retracted state, and the fixed cover plate 41 is suspended inside the sliding plate 42 by the sliding block 47. The pressing rollers 46 and the conveying component 3 maintain a certain initial distance, which is greater than the thickness of the cotton material, so that the cotton material can pass smoothly. After receiving the start signal, the telescopic hydraulic cylinder 44 begins to extend, and its power is transmitted to the fixed cover plate 41 through the telescopic guide column 45. Under the push of the telescopic guide column 45, the fixed cover plate 41 slides downward inside the sliding plate 42 through the sliding blocks 47 at both ends, driving the pressing rollers 46 to descend synchronously. After the pressing rollers 46 contact the cotton material, as the fixed cover plate 41 continues to descend, pressure is applied to the cotton material, compacting it. At this time, the telescopic guide column 45 moves downward synchronously within the sliding plate 42 to ensure the stability of the pressing process. The initial distance between the cotton pressing roller 46 and the conveying component 3 is greater than the thickness of the cotton material, which prevents the cotton material from being squeezed and stuck due to the small distance when it is placed or conveyed to the conveying component 3, and ensures that the cotton material can smoothly enter the pressing area.

[0024] Please refer to Figure 1 , Figures 5 to 8 As shown, the leveling component 5 includes a fixed bracket 51. One end of each of the two fixed brackets 51 is fixedly installed at the upper end of the carding machine mechanism 1. A frame 52 is fixedly installed on the opposite side of each of the two fixed brackets 51. An opening 55 is provided through the inner wall of each frame 52. A first fixed plate 53 and a second fixed plate 54 are fixedly installed at the top of the frame 52 near both ends. A sliding rod is fixedly sleeved inside the opposite side of the first fixed plate 53 and the second fixed plate 54. A first movable frame 513 and a second movable frame 514 are slidably sleeved on the outer side of the sliding rod near both ends. A connecting rod 518 is fixedly installed at the lower end of the first movable frame 513 and the second movable frame 514.

[0025] Furthermore, a first moving rod 515 and a second moving rod 516 are fixedly installed at the lower end of the connecting rod 518, and the connecting rod 518 is slidably sleeved inside the opening 55. The lower ends of the first moving rod 515 and the second moving rod 516 are fixedly connected to a leveling scraper 517.

[0026] Furthermore, a mounting bracket 56 is fixedly installed at the center of the upper end of the frame 52, a connecting plate 57 is fixedly installed at the upper end of the mounting bracket 56, a servo motor 58 is fixedly installed at the upper end of the connecting plate 57, the output shaft of the servo motor 58 is sleeved inside the connecting plate 57, the output shaft of the servo motor 58 is fixedly connected to the rotating rod 59, a gear 510 is fixedly connected at the lower end of the rotating rod 59, a first spur gear 511 and a second spur gear 512 are respectively meshed on the outer side of the gear 510, one end of the first spur gear 511 is fixedly installed at the lower end of the upper end of the first movable frame 513, and one end of the second spur gear 512 is fixedly installed at the lower end of the upper end of the second movable frame 514.

[0027] In a specific embodiment, when the cotton layer is conveyed to the lower part of the leveling component 5, firstly, after the servo motor 58 is powered on, the output shaft drives the rotating rod 59 to rotate, and the gear 510 at the lower end of the rotating rod 59 rotates accordingly, thereby driving the first straight tooth rod 511 and the second straight tooth rod 512 to move relative to each other, thereby driving the first movable frame 513 and the second movable frame 514 to slide relative to each other on the sliding rod. Through the relative movement of the first movable frame 513 and the second movable frame 514, the connecting rod 518 is driven to move inside the opening 55 of the frame 52. Finally, the first moving rod 515 and the second moving rod 516 are driven to move back and forth relative to each other. When the first moving rod 515 and the second moving rod 516 move back and forth relative to each other, they further drive the multiple leveling scrapers 517 to move back and forth. Through this reciprocating motion, the scrapers continuously comb and smooth the surface of the cotton layer, eliminating material accumulation or uneven thickness, achieving leveling, and at the same time dealing with the uneven dispersion on both sides of the cotton layer.

[0028] The working principle and usage process of this device are as follows: When the conveying component 3 is stationary or running at low speed, the cotton material is placed or conveyed above the conveying component 3, directly below the two pressing rollers 46. The telescopic hydraulic cylinder 44 is in its initial retracted state, and the fixed cover plate 41 is suspended inside the sliding plate 42 by the sliding block 47. The pressing rollers 46 and the conveying component 3 maintain a certain initial distance, which is greater than the thickness of the cotton material, so that the cotton material can pass through smoothly. After receiving the start signal, the telescopic hydraulic cylinder 44 begins to extend, and its power is transmitted to the fixed cover plate 41 through the telescopic guide column 45. Under the push of the telescopic guide column 45, the fixed cover plate 41 slides downward inside the sliding plate 42 through the sliding blocks 47 at both ends, driving the pressing rollers 46 to descend synchronously. After the pressing rollers 46 contact the cotton material, as the fixed cover plate 41 continues to descend, pressure is applied to the cotton material, compacting it. At this time, the telescopic guide column 45 moves downward synchronously within the sliding plate 42 to ensure the stability of the pressing process. The initial distance between the cotton pressing roller 46 and the conveying component 3 is greater than the thickness of the cotton material, preventing the cotton material from being squeezed and jammed due to insufficient distance when placed or conveyed to the conveying component 3, ensuring that the cotton material can smoothly enter the pressing area. Then, when the cotton layer is conveyed to the bottom of the equalizing component 5, firstly, after the servo motor 58 is powered on, the output shaft drives the rotating rod 59 to rotate, and the gear 510 at the lower end of the rotating rod 59 rotates accordingly, thereby driving the first straight tooth rod 511 and the second straight tooth rod 512 to move relative to each other, thereby driving the first movable frame 513 and the second movable frame 512 to move relative to each other. 4. The sliding rod slides relative to the sliding rod, and moves relative to the first movable frame 513 and the second movable frame 514, thereby driving the connecting rod 518 to move inside the opening 55 of the frame 52. Finally, it drives the first moving rod 515 and the second moving rod 516 to move back and forth relative to each other. When the first moving rod 515 and the second moving rod 516 move back and forth relative to each other, they further drive multiple leveling scrapers 517 to move back and forth. Through this reciprocating motion, the scrapers continuously comb and level the surface of the cotton layer, eliminating material accumulation or uneven thickness, achieving leveling, and at the same time dealing with the uneven dispersion on both sides of the cotton layer.

[0029] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
