Description

Technical Field

[0001] The present invention relates to the field of carding machines, and more particularly to a carding machine autoleveling control device. Background Art

[0002] Carding machines are used in the textile industry to comb, clean, loosen, and evenly condition cotton or other fiber materials. Their purpose is to improve fiber quality and provide higher-quality textile raw materials for subsequent spinning. During cotton processing, carding machines not only remove impurities but also ensure even fiber distribution through leveling techniques, thereby improving the performance of textile products. The primary function of autoleveling control equipment is to regulate the carding machine's operating state through automated systems, ensuring fiber uniformity and consistency. While traditional carding machines may require manual adjustment, modern autoleveling control systems can automatically adjust various machine parameters, such as fiber density and carding speed, based on actual needs.

[0003] In the prior art, a large amount of cotton is usually placed on a conveying device, and the cotton layer is transported to the inside of a carding machine through the conveying device. However, in the process of transporting the cotton layer to the inside of the carding machine, most of the cotton is first placed on the conveying device, and the cotton layer is transported by the operation of the conveying device to enter the inside of the carding machine.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0020] Please refer to Figure 1 and Figure 2 As shown, a self-adjusting and leveling control device for a cotton carding machine includes a cotton carding machine mechanism 1, one end of the inner wall of the cotton carding machine mechanism 1 is rotatably sleeved with a winding roller 6, one end of the cotton carding machine mechanism 1 is provided with a transmission component 3 for transmitting the cotton layer, the lower end of the transmission component 3 is fixedly connected to a supporting leg 2, the upper end of the transmission component 3 is provided with a cotton pressing component 4 for evenly adjusting the thickness of the cotton layer, and the upper end of the transmission component 3 is provided with a leveling component 5 for dispersing and leveling the two 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 the cotton layer is conveyed toward the carding machine mechanism 1. The cotton pressing component 4 is arranged at the upper end of the conveying component 3, and its main function is to preliminarily adjust the thickness of the cotton layer. When the cotton layer passes under the cotton pressing component 4, the cotton pressing component 4 applies downward pressure to the thicker areas of the cotton layer through its own pressure. Under the action of pressure, the cotton fibers in the thicker areas will be squeezed, making the thickness of the cotton layer tend to be uniform. The mixing component 5 is also located at the upper end of the conveying component 3. It mainly deals with the uneven dispersion on both sides of the cotton layer. During the transmission of the cotton layer, if the fibers on both sides of the cotton layer are unevenly distributed, and the cotton fibers in some areas are loose or piled up, the mixing component 5 will pass through a specific mechanical structure. When the cotton layer passes, these structures will move the fibers on both sides of the cotton layer. When the cotton layer reaches the position of the winding roller 6, the winding roller 6 rotates and rolls the cotton layer into the subsequent combing components inside the carding machine mechanism 1. Inside the carding machine mechanism 1, the cotton layer will undergo a series of complex combing processes such as opening, combing, and impurity removal, and is finally made into cotton strips that meet the requirements. The carding machine opens, combs, removes impurities and mixes the fiber raw materials through mechanical action, and finally processes the fibers into a cotton web or cotton strips in a single fiber state. The core of the process is to use high-speed rotating combing elements (such as licker-in, cylinder, doffer, etc.) to repeatedly comb the fibers while removing impurities.

[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 with sliding blocks 47. The two sliding blocks 47 are slidably connected to the inside of the sliding plate 42. Telescopic guide columns 45 are provided inside the two sliding plates 42. The lower ends of the two sliding plates 42 are fixedly installed on both sides of the upper end of the transmission assembly 3. Cotton pressing rollers 46 are rotatably sleeved on both sides of the lower end of the fixed cover plate 41. Telescopic guide columns 45 are fixedly installed on the upper end of the fixed cover plate 41. Sliding grooves 43 are provided inside the sliding plates 42. The telescopic guide column 45 is sleeved inside one of the sliding plates 42. The upper end of the telescopic guide column 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 in a stationary or low-speed running state, the cotton material is placed or conveyed to the top of the conveying component 3, located in the area directly below the two cotton pressing rollers 46, the telescopic hydraulic cylinder 44 is in an initial contraction state, and the fixed cover 41 is suspended in the sliding plate 42 through the sliding block 47. A certain initial distance is maintained between the cotton pressing roller 46 and the conveying component 3. At this time, the distance 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 41 through the telescopic guide column 45. Under the push of the telescopic guide column 45, the fixed cover 41 slides downward inside the sliding plate 42 through the sliding blocks 47 at both ends, driving the cotton pressing roller 46 to descend synchronously. After the cotton pressing roller 46 contacts the cotton material, as the fixed cover 41 continues to descend, pressure is applied to the cotton material to compact the cotton material. At this time, the telescopic guide column 45 moves downward synchronously in the sliding plate 42 to ensure the stability of the pressing process. The initial spacing between the cotton pressing roller 46 and the conveying component 3 is greater than the thickness of the cotton material, which avoids the cotton material being squeezed and stuck due to the small spacing when it is placed or transported to the conveying component 3, ensuring that the cotton material can smoothly enter the cotton pressing area.

[0024] Please refer to Figure 1 、 Figures 5 to 8 As shown, the mixing assembly 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 cotton carding machine mechanism 1, and a frame 52 is fixedly installed on the opposite side of the two fixed brackets 51. The inner wall of the frame 52 is penetrated by a through opening 55, and a first fixed plate 53 and a second fixed plate 54 are fixedly installed at the top and ends of the frame 52 respectively. The first fixed plate 53 and the second fixed plate 54 are fixedly sleeved on the opposite sides of the first fixed plate 53 and the second fixed plate 54. The outer side of the sliding rod is slidably sleeved with a first movable frame 513 and a second movable frame 514 at the two ends, and the lower ends of the first movable frame 513 and the second movable frame 514 are fixedly installed with a connecting rod 518.

[0025] Furthermore, the lower ends of the connecting rod 518 are fixedly installed with the first moving rod 515 and the second moving rod 516, and the connecting rod 518 is slidably sleeved inside the through opening 55. The lower ends of the first moving rod 515 and the second moving rod 516 are fixedly connected with the evenly adjusting 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 through the inside of the connecting plate 57, the output shaft of the servo motor 58 is fixedly connected to the rotating rod 59, the lower end of the rotating rod 59 is fixedly connected to the gear 510, the outer side of the gear 510 is respectively engaged with the first spur rod 511 and the second spur rod 512, one end of the first spur rod 511 is fixedly installed at the upper end of the first movable frame 513, and one end of the second spur rod 512 is fixedly installed at the upper end of the second movable frame 514.

[0027] In a specific embodiment, when the cotton layer is transferred to the bottom of the mixing component 5, first, after the servo motor 58 is energized, 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, and then 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, and 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, multiple mixing scrapers 517 are further driven to move back and forth. Through this reciprocating motion, the scrapers continuously comb and flatten the surface of the cotton layer, eliminate material accumulation or uneven thickness, achieve mixing, and at the same time deal with the uneven dispersion on both sides of the cotton layer.

[0028] The working principle and usage process of this device: When the conveying component 3 is in a stationary or low-speed running state, the cotton material is placed or conveyed to the top of the conveying component 3, located in the area directly below the two cotton pressing rollers 46, the telescopic hydraulic cylinder 44 is in an initial contraction state, and the fixed cover 41 is suspended in the sliding plate 42 through the sliding block 47. A certain initial spacing is maintained between the cotton pressing roller 46 and the conveying component 3. At this time, the spacing 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 41 through the telescopic guide column 45. Under the push of the telescopic guide column 45, the fixed cover 41 slides downward inside the sliding plate 42 through the sliding blocks 47 at both ends, driving the cotton pressing roller 46 to descend synchronously. After the cotton pressing roller 46 contacts the cotton material, as the fixed cover 41 continues to descend, pressure is applied to the cotton material to compact the cotton material. At this time, the telescopic guide column 45 moves downward synchronously in the sliding plate 42 to ensure the stability of the pressing process. The initial spacing between the cotton pressing roller 46 and the conveying component 3 is greater than the thickness of the cotton material, which avoids the cotton material from being squeezed and stuck due to the small spacing when it is placed or conveyed to the conveying component 3, ensuring that the cotton material can smoothly enter the cotton pressing area. Afterwards, when the cotton layer is conveyed to the bottom of the mixing component 5, first, after the servo motor 58 is energized, 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 51 The first movable frame 513 and the second movable frame 514 slide relative to each other on the sliding rod, and move relative to each other through 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, and finally driving the first movable rod 515 and the second movable rod 516 to move back and forth relative to each other. When the first movable rod 515 and the second movable rod 516 move back and forth relative to each other, the multiple smoothing scraping blocks 517 are further driven to move back and forth. Through this reciprocating motion, the scraping blocks continuously comb and flatten the surface of the cotton layer, eliminating material accumulation or uneven thickness, achieving smoothing, and at the same time dealing with uneven dispersion on both sides of the cotton layer.

[0029] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
