Description

Technical Field

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

[0002] During the operation of the carding machine, cotton laps or layers are continuously fed in from the feeding mechanism. After being held by the feeding rollers and the feeding plate (or lower feeding plate), they are opened and initially carded by the licker-in rollers. This feeding process is the starting point of the entire carding process, and its uniformity directly affects the subsequent carding quality and the evenness of the final sliver.

[0003] In actual production, factors such as fluctuations in raw material ratios, uneven lap formation during the opening and cleaning process, and changes in lap unwinding tension cause varying degrees of quantitative fluctuations in the cotton layer fed into the carding machine in both the longitudinal and transverse directions. This unevenness is not only manifested in differences in cotton layer thickness but also in local variations in weight per unit area (i.e., cotton layer density). When the cotton layer has a higher quantitative weight, greater thickness, or higher local density, the reaction force experienced by the feed roller during the pressure gripping process increases significantly, especially the problem of uneven force distribution along the length of the feed roller.

[0004] Specifically, in the bearing support areas at both ends of the feeding roller, the structure is relatively rigid and deforms less under pressure, resulting in a greater gripping force on the cotton layer. However, in the middle of the feeding roller, due to the elastic deformation of the cantilever support structure, the actual applied pressure is weakened, leading to a relatively insufficient gripping force. This problem is further amplified when the thickness and density of the fed cotton layer are uneven: in areas with high cotton layer density and thickness, the gripping at both ends is too tight, while in the middle, the pressure is concentrated at both ends, causing a "bridging" phenomenon, resulting in the cotton layer in the middle not being effectively gripped; conversely, in areas with thin or soft cotton layers, the overall gripping force decreases, making slippage or intermittent cotton feeding more likely.

[0005] This uneven gripping force along the roller axis directly causes inconsistent gripping force of the licker-in on the cotton layer. In areas with strong gripping force, the cotton layer is smoothly and stably stripped into the licker-in for opening; while in areas with weak or absent gripping force, the cotton layer is prone to slippage, retention, or even local accumulation, resulting in reduced or discontinuous gripping by the licker-in. As a result, the fiber flow rate entering the main carding zone fluctuates more significantly, and defects such as cloudiness, holes, or uneven thickness appear on the cotton web, seriously affecting the weight uniformity and evenness of the sliver. Utility Model Content

[0006] The purpose of this invention is to provide a carding machine leveling structure that can effectively level the cotton material in the front area of ​​the carding machine, ensuring that the licker-in roller can stably and evenly peel off the cotton layer, laying the foundation for high-quality carding in the future.

[0007] To solve the above-mentioned technical problems, this utility model provides a carding machine leveling structure, including a leveling cover horizontally arranged at the feeding inlet of the carding machine. The leveling cover opens to the side facing the cotton material, and has an inlet in the direction of cotton material entry. A forward-moving conveyor belt and a reverse-moving conveyor belt are movably arranged horizontally inside the leveling cover. The outer periphery of the forward-moving conveyor belt is provided with several forward annular protruding push strips that are respectively and inclined along its length direction. The outer periphery of the reverse-moving conveyor belt is provided with several reverse annular protruding push strips that are respectively and inclined along its length direction. The inclination directions of the forward annular protruding push strips are opposite to those of the reverse annular protruding push strips. Both ends of the forward-moving conveyor belt are provided with a first drive shaft rotatably connected to the leveling cover. Both ends of the reverse-moving conveyor belt are provided with a second drive shaft rotatably connected to the leveling cover. A drive motor for driving all drive shafts to rotate in the same direction is installed outside the leveling cover.

[0008] By adopting the above technical solution, when the cotton material enters the leveling hood from the cotton inlet, due to the rotation of the forward and reverse pushing conveyor belts, and the opposite inclination direction of the forward and reverse annular protruding pushers, the forward annular protruding pushers on the forward pushing conveyor belt push the cotton material forward, and the reverse annular protruding pushers on the reverse pushing conveyor belt push the cotton material backward. Under the combined action of the forward and reverse pushing forces, the cotton material is fully leveled in the leveling hood, and the cotton layer that was originally of uneven thickness and density is gradually adjusted to be uniform.

[0009] The present invention is further configured such that each positive annular protrusion pusher has a plurality of positive push teeth on its outer periphery, and each negative annular protrusion pusher has a plurality of negative push teeth on its outer periphery.

[0010] The present invention is further configured such that each forward push tooth and each reverse push tooth are inclined toward the cotton inlet when they are located near the opening of the leveling cover.

[0011] The present invention is further configured such that each forward push tooth and each reverse push tooth are smoothly disposed.

[0012] The present invention is further configured such that, inside the leveling cover, a central cleaning baffle is laterally arranged at the lower part between the forward pushing conveyor belt and the reverse pushing conveyor belt, and central scraping openings corresponding to the forward pushing teeth and the reverse pushing teeth are respectively opened on both sides of the central cleaning baffle. Inside the leveling cover, an edge cleaning baffle is laterally arranged at the lower part of the reverse pushing conveyor belt away from the forward pushing conveyor belt, and edge scraping openings corresponding to the reverse pushing teeth are opened on the edge of the edge cleaning baffle.

[0013] The present invention is further configured such that the power output shaft of the drive motor is connected to one end of one of the first drive shafts, the other end of the first drive shaft connected to the drive motor extends out of the leveling cover and is provided with a first pulley, and one end of one of the second drive shafts extends out of the leveling cover and is provided with a second pulley, and the first pulley and the second pulley are driven by a belt.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, the carding machine's leveling structure, through a unique design of forward and reverse-direction pusher belts, combined with annular raised pushers and pushers in opposite directions, effectively levels the cotton material before it enters the carding machine. This not only solves the problems of large quantitative fluctuations and uneven density in the cotton layer fed into traditional carding machines, but also significantly improves the stability and uniformity of the cotton layer gripped by the licker-in roller, thereby reducing defects such as cloudiness, holes, and uneven thickness in the cotton web, and improving the weight uniformity and evenness of the sliver.

[0016] Secondly, the installation of the central cleaning baffle and the edge cleaning baffle effectively prevents the residue and accumulation of cotton material during the uniformization process, ensuring the continuous and efficient operation of the equipment. 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 machine leveling structure proposed in 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, used only 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 1-3 A carding machine leveling structure includes a leveling cover 1 horizontally positioned at the carding machine feed inlet. The leveling cover 1 has an opening facing the cotton material, and an inlet 2 is provided in the opening facing the direction of cotton material entry. A forward-driving conveyor belt 3 and a reverse-driving conveyor belt 4 are movably arranged horizontally inside the leveling cover 1. Both ends of the forward-driving conveyor belt 3 are provided with a first drive shaft 5 rotatably connected to the leveling cover 1. Both ends of the reverse-driving conveyor belt 4 are provided with a second drive shaft 6 rotatably connected to the leveling cover 1. A drive motor 7 is installed outside the leveling cover 1. The power output shaft of the drive motor 7 is connected to one end of one of the first drive shafts 5. The other end of the first drive shaft 5 connected to the drive motor 7 extends out of the leveling cover 1 and is provided with a first pulley 8. One end of one of the second drive shafts 6 extends out of the leveling cover 1 and is provided with a second pulley 9. The first pulley 8 and the second pulley 9 are driven by a belt 10, so that the drive motor 7 can drive the forward-driving conveyor belt 3 and the reverse-driving conveyor belt 4 to move in the same direction.

[0023] The outer periphery of the forward-pushing conveyor belt 3 is provided with several forward-facing annular protruding pushers 11, which are respectively inclined along its length direction. When the forward-pushing conveyor belt 3 rotates, the forward-facing annular protruding pushers 11 move the protruding cotton material in the forward direction. The outer periphery of the reverse-pushing conveyor belt 4 is provided with several reverse-facing annular protruding pushers 12, which are respectively inclined along its length direction. The inclination direction of the forward-facing annular protruding pushers 11 and the reverse-facing annular protruding pushers 12 is opposite. When the reverse-facing annular protruding pushers 12 rotate with the reverse-pushing conveyor belt 4, they move the protruding cotton material in the reverse direction. Each positive annular protruding pusher 11 has multiple positive push teeth 13 on its outer periphery, and each negative annular protruding pusher 12 has multiple negative push teeth 14 on its outer periphery. Each positive push tooth 13 and each negative push tooth 14 are inclined toward the cotton inlet 2 when they are located near the opening of the leveling cover 1. Each positive push tooth 13 and each negative push tooth 14 are smoothly arranged. The increase of positive push teeth 13 and negative push teeth 14 can increase the ability to push the cotton material to both ends.

[0024] A central cleaning baffle 15 is horizontally arranged at the lower part of the leveling cover 1 between the forward pushing conveyor belt 3 and the reverse pushing conveyor belt 4. The two sides of the central cleaning baffle 15 are respectively provided with central scraping holes 16 corresponding to the forward pushing teeth 13 and the reverse pushing teeth 14. When the forward pushing teeth 13 and the reverse pushing teeth 14 pass through the central scraping holes 16, the fibers wrapped on the forward pushing teeth 13 and the reverse pushing teeth 14 can be hung off. An edge cleaning baffle 17 is horizontally arranged at the lower part of the reverse pushing conveyor belt 4 away from the forward pushing conveyor belt 3. The edge of the edge cleaning baffle 17 is provided with edge scraping holes 18 corresponding to the reverse pushing teeth 14. When the reverse pushing teeth 14 pass through the edge scraping holes 18, the fibers wrapped on the reverse pushing teeth 14 can be hung off.

[0025] Working principle: When the cotton material enters the leveling hood 1 from the cotton inlet 2, due to the rotation of the forward pushing conveyor belt 3 and the reverse pushing conveyor belt 4, and the opposite inclination of the forward annular protruding pusher 11 and the reverse annular protruding pusher 12, the forward pushing conveyor belt 3 pushes the cotton material forward, and the reverse pushing conveyor belt 4 pushes the cotton material in the reverse direction. Under the combined action of the forward and reverse pushing forces, the cotton material is fully leveled in the leveling hood 1, and the cotton layer that was originally of uneven thickness and density is gradually adjusted to be uniform. The central cleaning baffle 15 and the edge cleaning baffle 17, through the central scraper 16 and the edge scraper 18, can promptly remove the fibers wrapped around the forward pusher 13 and the reverse pusher 14, preventing the fibers from tangling and affecting the normal operation of the pusher. This ensures the continuous and stable operation of the entire carding machine's leveling structure, and ensures that the licker-in roller can stably and evenly peel off the leveled cotton layer, laying a solid foundation for subsequent high-quality carding.

[0026] 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.
