Description

Technical Field

[0001] This utility model belongs to the field of textile processing technology and relates to a carding machine combing mechanism. Background Technology

[0002] In the textile industry, the carding machine, as a crucial piece of equipment for processing cotton or other fibrous materials into relatively uniform fiber slivers, plays a vital role in improving the quality of the final product and production efficiency through the design and optimization of its carding mechanism. The traditional carding machine's carding mechanism mainly includes core components such as the cylinder, doffer, licker-in roller, and flat cover system. These components work together to open, separate, comb, and arrange the fibers, thereby ensuring the quality and consistency of the fiber sliver.

[0003] Specifically, the cylinder, a large-diameter cylinder, is covered with serrated or needle-like combing elements. It works in conjunction with a doffer, a smaller cylinder, and the working area between them effectively separates and combs the fibers meticulously. Furthermore, the cover plate system consists of a series of elongated plates, also equipped with carding cloth, which fits tightly with the cylinder to further comb and clean the fibers as they pass through. While this design has achieved significant results in improving fiber quality, the limitations of existing technology are becoming increasingly apparent as market demands diversify and product quality requirements continue to rise.

[0004] Especially when processing different types of fiber materials, a major challenge faced by existing carding machine carding mechanisms is the lack of flexibility in adjusting the spacing. Currently, most carding machines have adjustable flush plates, allowing operators to flexibly adjust them according to different fiber types and processing needs to achieve optimal carding results. However, the position of the fixed flush plates is usually fixed and cannot be adjusted as needed. This limitation makes it difficult for carding machines to achieve ideal carding conditions when dealing with different types of fibers (such as cotton, wool, and synthetic fibers), thus affecting fiber sliver quality and production flexibility. Utility Model Content

[0005] The purpose of this invention is to provide a carding machine combing mechanism in which the gaps of the cover plates around the cylinder can be adjusted to better adapt to the processing needs of various fiber types.

[0006] To solve the above-mentioned technical problems, this utility model provides a carding machine carding mechanism, including a cylinder, with multiple licker-in rollers arranged on one side of the cylinder, a doffer arranged on the side of the cylinder away from the licker-in rollers, and a stripping roller arranged on the side of the doffer away from the cylinder, cooperating with it. A movable cover plate is movably arranged above the cylinder, and a carding cloth driven by a chain is movably arranged inside the movable cover plate. Arc-shaped cover plates are movably arranged on both sides and below the cylinder, and the inner wall of each arc-shaped cover plate is provided with carding grooves that correspond to the surface of the cylinder. The unit has fixed comb teeth that cooperate with each other. A cotton inlet channel is left between the two arc-shaped cover plates near the licker-in roller of the cylinder, and a cotton outlet channel is left between the two arc-shaped cover plates near the doffer of the cylinder. Both ends of the cylinder are provided with end caps that are rotatably connected to them. Each end cap is fixedly connected to the body of the carding machine. Both ends of the movable cover plate and both ends of each arc-shaped cover plate are provided with connecting ends. A central mounting platform is provided in the middle of each end cap. A hydraulic telescopic rod is connected between each connecting end and the corresponding central mounting platform. Each hydraulic telescopic rod is oriented towards the center of the cylinder.

[0007] By employing the above technical solution, the fibers are effectively loosened and opened by the sharp teeth on the licker-in roller, and then conveyed to the cylinder. The cylinder rotates at high speed, and the combing unit on its surface grabs and conveys the fibers. The carding cloth in the movable cover plate and the fixed comb teeth in the arc-shaped cover plate work closely with the cylinder to comb and clean the fibers as they pass through. The doffer and the cylinder work together to further refine the fibers and arrange them neatly. The stripping roller peels the fibers off the doffer and arranges them into strips by the cotton collecting device for further processing. When the spacing needs to be adjusted, both the movable cover plate and the arc-shaped cover plate can be extended or retracted towards the center of the cylinder via two hydraulic telescopic rods at both ends, allowing for quick and direct spacing adjustment.

[0008] The present invention is further configured such that multiple licker-in rollers are covered by a cotton inlet cover, the side of the cotton inlet cover away from the cylinder is provided with a cotton inlet, the side of the cotton inlet cover away from the cotton inlet is connected to the cotton inlet channel, the cotton inlet cover is connected to two end caps at the cotton inlet channel, the doffer and the stripping roller are covered by a cotton outlet cover, the side of the cotton outlet cover away from the cylinder is provided with a cotton outlet, the side of the cotton outlet cover away from the cotton outlet is connected to the cotton outlet channel, and the cotton inlet cover is connected to two end caps at the cotton outlet channel.

[0009] The present invention is further configured such that each arc-shaped cover plate has a flexible sealing strip connected to the edge of the adjacent arc-shaped cover plate, the edge of the movable cover plate, the edge of the cotton inlet cover, or the edge of the cotton outlet cover.

[0010] The present invention is further configured such that the flexible sealing strip is made of polyurethane material.

[0011] The present invention is further configured such that both ends of the movable cover plate and both ends of each arc-shaped cover plate are provided with sealing cover plates that are slidably connected to the corresponding end cover, and each sealing cover plate is arranged in the circular direction of the corresponding end cover.

[0012] The present invention is further configured such that a rotating hole is provided in the middle of each end cap, and both ends of the cylinder are provided with rotating shafts that are rotatably connected to the corresponding rotating holes.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, the movable cover plate and the arc-shaped cover plate of this utility model are both adjusted in distance towards the center of the cylinder by two hydraulic telescopic rods at both ends, which can better adapt to the processing needs of various fiber types, further optimize the combing effect, reduce fiber damage, and provide a strong guarantee for improving product quality and production efficiency.

[0015] Secondly, when the gap between the movable cover plate and the arc-shaped cover plate is adjusted, the sealing cover plate can cooperate with the end cover to wrap the cylinder. With the connection of the flexible sealing strip, it can effectively prevent fibers from flying out and polluting the production environment. Attached Figure Description

Detailed Implementation

[0021] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the carding mechanism of this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0022] Example, refer to Figure 1-4 A carding machine carding mechanism includes a cylinder 1, with two licker-in rollers 2 on one side of the cylinder 1, a doffer 3 on the side of the cylinder 1 away from the licker-in rollers 2, and a stripping roller 4 on the side of the doffer 3 away from the cylinder 1. A movable cover plate 5 is movably mounted above the cylinder 1, and a carding cloth (not shown) driven by a chain is movably mounted inside the movable cover plate 5. An arc-shaped cover plate 6 is movably mounted on both sides and below the cylinder 1, and the inner wall of each arc-shaped cover plate 6 is provided with fixed comb teeth that cooperate with the carding unit on the surface of the cylinder 1. A cotton inlet channel 7 is left between the two arc-shaped cover plates 6 near the licker-in rollers 2 of the cylinder 1, so that fibers can be transported into the cylinder 1 by the licker-in rollers 2 through the cotton inlet channel 7. A cotton outlet channel 8 is left between the two arc-shaped cover plates 6 near the doffer 3 of the cylinder 1, so that the fibers combed by the cylinder 1 enter the doffer 3 through the cotton outlet channel 8.

[0023] Both ends of the cylinder 1 are provided with an end cap 9 that is rotatably connected to it. Each end cap 9 has a rotating hole 10 in the middle. Both ends of the cylinder 1 are provided with a rotating shaft 11 that is rotatably connected to the corresponding rotating hole 10. Both ends of the movable cover plate 5 and both ends of each arc-shaped cover plate 6 are provided with a connecting end 12. Each end cap 9 has a central mounting platform 13 in the middle. Each connecting end 12 is connected to the corresponding central mounting platform 13 with a hydraulic telescopic rod 14. Each hydraulic telescopic rod 14 is set towards the center of the cylinder 1. The movable cover plate 5 and the arc-shaped cover plate 6 are adjusted at intervals towards the center of the cylinder 1 through the two hydraulic telescopic rods 14 at both ends. Both ends of the movable cover plate 5 and both ends of each arc-shaped cover plate 6 are provided with a sealing cover plate 15 that is slidably connected to the corresponding end cover 9. Each sealing cover plate 15 is arranged in the circular direction of the corresponding end cover 9, so that when the gap between the movable cover plate 5 and the arc-shaped cover plate 6 is adjusted, the sealing cover plate 15 can cooperate with the end cover 9 to wrap the cylinder 1 and prevent the fibers from flying out.

[0024] The multi-pinning roller 2 is covered by a cotton inlet cover 16. The cotton inlet cover 16 has a cotton inlet 17 on the side away from the cylinder 1. The side of the cotton inlet cover 16 away from the cotton inlet 17 is connected to the cotton inlet channel 7. The cotton inlet cover 16 is connected to two end caps 9 at the cotton inlet channel 7. The doffer 3 and the stripping roller 4 are covered by a cotton outlet cover 18. The cotton outlet cover 18 has a cotton outlet 19 on the side away from the cylinder 1. The side of the cotton outlet cover 18 away from the cotton outlet 19 is connected to the cotton outlet channel 8. The cotton inlet cover 16 is connected to two end caps 9 at the cotton outlet channel 8. Each arc-shaped cover plate 6 has a flexible sealing strip 20 connected to the edge of the adjacent arc-shaped cover plate 6, the edge of the movable cover plate 5, the edge of the cotton inlet cover 16, or the edge of the cotton outlet cover 18. The flexible sealing strip 20 is made of polyurethane. Polyurethane has high wear resistance, good elasticity and tear resistance. It can effectively wrap the cylinder 1 when the gap between the movable cover plate 5 and the arc-shaped cover plate 6 is adjusted to prevent the fibers from flying out.

[0025] Working principle: The fibers pass through the sharp teeth on the licker-in roller 2, which effectively loosens and opens up the fiber clumps and conveys the fibers to the cylinder 1. The cylinder 1 rotates at high speed, and the combing unit on its surface grabs and conveys the fibers. The card cloth in the movable cover plate 5 and the fixed comb teeth in the arc-shaped cover plate 6 work closely with the cylinder 1 to comb and clean the fibers as they pass through. The doffer 3 works in conjunction with the cylinder 1 to further refine the fibers and arrange them neatly. The stripping roller 4 peels the fibers off the doffer 3 and sorts them into strips through the cotton collection device for further processing.

[0026] When the spacing needs to be adjusted, both the movable cover plate 5 and the arc-shaped cover plate 6 can extend and retract towards the center of the cylinder 1 via the two hydraulic telescopic rods 14 at both ends, which allows for quick and direct spacing adjustment. During the process, the sealing cover plate 15 slides accordingly, and through the connection of the flexible sealing strip 20, the cylinder 1 can be effectively wrapped by the movable cover plate 5 and the arc-shaped cover plate 6 when the spacing is adjusted, preventing fibers from flying out.

[0027] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.
