Description

Technical Field

[0001] This utility model relates to the field of wool combing machine technology, specifically to a licker-in roller structure for a wool combing machine. Background Technology

[0002] Wool carding machines are key equipment in wool textile production, primarily using the coordinated action of multiple rollers to open, card, and remove impurities from wool raw materials. Existing carding machines typically include components arranged sequentially in the process sequence, such as feed rollers, licker-in rollers, and pre-carding cylinders. The licker-in roller is responsible for the initial opening of the raw material fed in by the feed rollers. Current structures only have a single licker-in roller, whose high-speed rotation achieves the opening effect.

[0003] The existing carding roller structure lacks an effective sorting mechanism. Regardless of size or weight, the opened fibers are directly thrown into the pre-carding cylinder. This results in the lighter opened fibers being mixed with the heavier unopened fiber bundles and impurities, making effective separation impossible. This not only causes incomplete removal of impurities, affecting the quality of subsequent carding, but also damages some opened fibers due to over-processing. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a licker-in roller structure for a wool combing machine.

[0005] The technical solution of this utility model is as follows: A licker-in roller structure for a wool combing machine is installed between a feeding roller and a pre-combing cylinder. The feeding roller is arranged near the rear of the wool combing machine, and the pre-combing cylinder is located in front of the feeding roller. The structure includes a main licker-in roller, an auxiliary roller, and a fixed baffle. Both the main licker-in roller and the auxiliary roller are installed on the body of the wool combing machine and are respectively connected to a drive motor adapted to them. The main piercing roller is located in front of and below the feeding roller, with its axis parallel to the feeding roller's axis and lower than the horizontal plane where the feeding roller's axis is located; the auxiliary roller is located in front of and to the right of the main piercing roller, with its axis parallel to the main piercing roller's axis and higher than the horizontal plane where the main piercing roller's axis is located; a fixed baffle is set between the main piercing roller and the auxiliary roller, with the lower end of the baffle adjacent to the surface of the main piercing roller and the upper end extending towards the auxiliary roller; The outer surface of the main needle roller is provided with rigid needle cloth, and the surface of the auxiliary roller is provided with flexible needle cloth.

[0006] The main ginning roller, positioned at the lower front, effectively receives and forcefully opens the fibers from the feed roller, while the auxiliary roller, located at the upper right front, provides space for fiber transfer and gentle combing. Independent drive for each roller offers flexible speed adjustment capabilities.

[0007] The fixed baffle is an arc-shaped plate coaxial with the main needle roller. The height of the upper end of the baffle is no higher than the center line connecting the main needle roller and the auxiliary roller, and the upper end of the baffle is positioned close to the gap between the main needle roller and the auxiliary roller. Both ends of the fixed baffle are connected to the frame, and the length direction of the fixed baffle is consistent with the axis of the feed roller. The fixed baffle ensures that it forms a uniform and controllable slit with the surface of the main needle roller, which can stably guide the fiber flow.

[0008] The fixed baffle is positioned such that the minimum gap between the lower end of the fixed baffle and the surface of the main needle roller is 0.5-2mm. This effectively prevents fibers from scattering prematurely and ensures the consistency of the sorting action. At the same time, this gap is sufficient to prevent friction and wear between the baffle and the needle roller.

[0009] Preferably, the minimum gap between the auxiliary roller and the main needle roller is 3-8mm, forming a fiber transfer channel. The fiber transfer channel ensures that the fiber passes through smoothly, avoiding congestion or secondary impact in a narrow space, while also not being too large to weaken the effective stripping effect of the auxiliary roller on the fiber, thus ensuring efficient and stable fiber transfer from the main needle roller to the auxiliary roller.

[0010] Preferably, the ratio of the outer diameter of the main carding roller to the auxiliary roller is in the range of 1-1.5, and the ratio of the outer diameter of the pre-carding cylinder to the main carding roller is in the range of 2-4. The similar diameters of the main carding roller and the auxiliary roller facilitate fiber transfer; the pre-carding cylinder is much larger than the main carding roller, which meets its functional requirements as the main carding platform, and the huge surface area ensures sufficient carding time and space to accommodate subsequent work rollers.

[0011] Furthermore, the surface linear velocities of the main and auxiliary rollers at their approach points are opposite, resulting in opposite rotation. This "opposite rotation" at the approach point allows the needle cloth of the auxiliary roller to grab the fibers coming from the main roller, achieving a continuous and stable transfer of the fiber flow and preventing fiber backflow or entanglement.

[0012] Preferably, the horizontal plane of the auxiliary roller's axis is higher than the horizontal plane of the main quenching roller's axis, but lower than the horizontal plane of the pre-combed cylinder's axis. The height of the auxiliary roller facilitates the reception of fibers thrown up from the main quenching roller; the horizontal plane of the auxiliary roller's axis being lower than the horizontal plane of the pre-combed cylinder's axis conforms to the process flow of fibers from bottom to top, from being stripped from the auxiliary roller to the pre-combed cylinder, forming a smooth and natural fiber lifting path from opening and sorting to fine pre-combing.

[0013] Preferably, the horizontal plane of the main needle roller's axis is lower than the horizontal plane of the feed roller's axis. With the feed roller above and the main needle roller below, the fibers can hang down naturally after being fed from the feed roller, forming a loose fiber curtain. This facilitates efficient and smooth gripping by the main needle roller located below, avoiding problems such as poor feeding or fiber accumulation at the feeding point.

[0014] The beneficial effects of this utility model are as follows: By employing a coordinated layout of the main bar roller, auxiliary roller, and fixed baffle, a highly efficient fiber sorting unit can be embedded between the feeding and pre-combing processes of a traditional carding machine. Utilizing the principle of inertial sorting, the main bar roller's powerful opening and throwing action, the fixed baffle's interception and guidance, and the auxiliary roller's gentle combing and receiving action automatically return insufficiently opened heavy fibers to the recycling process, allowing opened light fibers to enter subsequent processes, thereby improving impurity removal efficiency and opening quality.

[0016] See Figure 1 , Figure 2 and Figure 3 As shown, a licker-in roller structure of a wool combing machine is installed between a feeding roller 2 and a pre-combing cylinder 6. The feeding roller 2 is arranged near the rear side of the wool combing machine, and the pre-combing cylinder is located in front of the feeding roller 2. It includes a main licker-in roller 3, an auxiliary roller 5, and a fixed baffle 4. The main licker-in roller 3 and the auxiliary roller 5 are both installed on the machine body 1 of the wool combing machine and are respectively connected to a drive motor adapted to them. The rotation speed of the main licker-in roller 3 is higher than that of the auxiliary roller 5.

[0017] In this embodiment, the main piercing roller 3 is located in front of and below the feeding roller 2, and its axis is parallel to the axis of the feeding roller 2 and lower than the horizontal plane where the axis of the feeding roller 2 is located; the auxiliary roller 5 is located in front of and to the right of the main piercing roller 3, and its axis is parallel to the axis of the main piercing roller 3 and higher than the horizontal plane where the axis of the main piercing roller 3 is located; the fixed baffle 4 is disposed between the main piercing roller 3 and the auxiliary roller 5, with the lower end of the fixed baffle 4 adjacent to the surface of the main piercing roller 3 and the upper end extending toward the auxiliary roller 5.

[0018] The horizontal plane of the axis of the main needle roller 3 is lower than the horizontal plane of the axis of the feed roller 2. With the feed roller 2 on top and the main needle roller 3 below, the fibers can hang down naturally after being fed out by the feed roller 2, forming a loose fiber curtain. This facilitates efficient and smooth gripping by the main needle roller 3 located below, avoiding problems such as poor feeding or fiber accumulation at the feeding point.

[0019] The surface linear velocities of the main needle roller 3 and the auxiliary roller 5 at their approach point are opposite, resulting in opposite rotation. This "opposite rotation" at the approach point allows the needle cloth of the auxiliary roller 5 to grab the fibers coming from the main needle roller 3, achieving a continuous and stable transfer of the fiber flow and avoiding fiber backflow or entanglement.

[0020] In this embodiment, the outer surface of the main needle roller 3 is provided with rigid needle cloth, which can be metal serrated needle cloth. The surface of the auxiliary roller 5 is provided with flexible needle cloth, which can be elastic polymer toothed needle cloth. The rigid needle cloth of the main needle roller 3 utilizes its high hardness and high strength characteristics to withstand the severe impact and tearing of the entangled fiber bundles, ensuring efficient opening. The flexible needle cloth of the auxiliary roller 5 has a certain degree of elasticity and toughness. When grasping, conveying and initially combing the opened fibers, the force is more gentle, which can effectively avoid damage such as tearing or cutting of individual fibers.

[0021] The fixed baffle 4 is an arc-shaped plate coaxial with the main needle roller 3. The height of the upper end of the baffle is no higher than the center line connecting the main needle roller 3 and the auxiliary roller 5, and the upper end of the fixed baffle 4 is positioned close to the gap between the main needle roller 3 and the auxiliary roller 5. Both ends of the fixed baffle 4 are connected to the frame, and the length direction of the fixed baffle 4 is consistent with the axial direction of the feed roller 2. The fixed baffle 4 ensures that it forms a uniform and controllable slit with the surface of the main needle roller 3, which can stably guide the fiber flow.

[0022] The minimum gap between the lower end of the fixed baffle 4 and the surface of the main needle roller 3 is 0.5-2mm, which can effectively prevent the fibers from flying off prematurely and ensure the consistency of the sorting action. At the same time, this gap is also sufficient to avoid friction and wear between the baffle and the needle cloth.

[0023] The minimum gap between the auxiliary roller 5 and the main needle roller 3 is 3-8mm, forming a fiber transfer channel. The fiber transfer channel ensures that the fiber passes through smoothly, avoiding congestion or secondary impact in a narrow space, while also not being too large to weaken the effective stripping effect of the auxiliary roller 5 on the fiber, thus ensuring efficient and stable fiber transfer from the main needle roller 3 to the auxiliary roller 5.

[0024] In this embodiment, the ratio of the outer diameter of the main carding roller 3 to the auxiliary roller 5 ranges from 1 to 1.5, and the ratio of the outer diameter of the pre-carding cylinder 6 to the main carding roller 3 ranges from 2 to 4. The main carding roller 3 and the auxiliary roller 5 have similar diameters, which is beneficial for fiber transfer; the pre-carding cylinder 6 is much larger than the main carding roller 3, which meets its functional requirements as the main carding platform, and the huge surface area ensures sufficient carding time and space to accommodate subsequent work rollers.

[0025] The horizontal plane of the axis of the auxiliary roller 5 is higher than the horizontal plane of the axis of the main shunt roller 3, but lower than the horizontal plane of the axis of the pre-combed cylinder 6. The height of the auxiliary roller 5 facilitates the reception of fibers thrown up from the main shunt roller 3; the horizontal plane of the axis of the auxiliary roller 5 being lower than the horizontal plane of the axis of the pre-combed cylinder 6 conforms to the process flow of fibers from bottom to top, from being stripped from the auxiliary roller 5 to the pre-combed cylinder 6, forming a smooth and natural fiber lifting path from opening and sorting to fine pre-combing.
