Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile machinery processing technology, and in particular to an adjustable cotton feeding device for a raw cotton impurity analyzer, which is suitable for fiber processing scenarios with different fiber lengths and varieties. Background Technology
[0002] In the textile fiber processing field, the cotton feeding device of a raw cotton impurity analyzer is a key component affecting fiber processing efficiency. Traditional cotton feeding devices generally use a fixed planar structure for the feeding table, and its main drawbacks are as follows:
[0003] First, flat surfaces easily create dead zones for material accumulation during the feeding process, especially when processing long fibers or raw materials with poor bulkiness. Increased frictional resistance between fibers leads to poor feeding, frequent blockages, and requires frequent manual intervention, severely impacting production efficiency. Second, the short fiber transport path and insufficient carding time under a flat structure make it difficult to fully open long fibers (such as cotton fibers ≥35mm) or high-tenacity synthetic fibers, easily causing fiber damage or incomplete impurity separation. Furthermore, traditional devices lack angle adjustment functionality, failing to flexibly adjust the feeding angle according to raw material characteristics, resulting in limited process adaptability and difficulty in meeting the processing needs of diverse fiber varieties such as cotton, linen, and synthetic fibers. Therefore, this solution proposes an adjustable feeding device for a raw cotton impurity analyzer. Utility Model Content
[0004] 1. Technical problem to be solved:
[0005] To address the problems existing in the prior art, this utility model proposes an adjustable cotton feeding device for a raw cotton impurity analyzer. Through an innovative arc-shaped table structure design and a multi-level angle adjustment mechanism, the feeding process is dynamically optimized. This device not only solves the technical pain points of traditional flat tables, such as low feeding efficiency and high dependence on manual labor, but also significantly improves the flexibility and reliability of the processing process by extending the fiber processing stroke and adapting to diverse fiber characteristics.
[0006] 2. Technical Solution:
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] An adjustable cotton feeding device for a raw cotton impurity analyzer includes a raw cotton impurity analyzer body. The inner cavity of the raw cotton impurity analyzer body is equipped with a combing roller. An arc-shaped cotton feeding platform and a matching roller shaft are provided in the front feeding area of the raw cotton impurity analyzer body. The axial projection of the roller shaft is located within the inner curved surface projection area of the arc-shaped cotton feeding platform.
[0009] A further improvement is that the arc-shaped cotton feeding platform includes a base, the base has a cavity inside, the cavity is equipped with an angle adjustment mechanism, the side wall of the base has guide holes and a ring array of positioning holes, the positioning holes are arranged radially with the guide holes as the center, and the outer wall of the base is equipped with a positioning adjustment component.
[0010] A further improvement is that the angle adjustment mechanism includes a transmission spindle, with both ends of the transmission spindle extending into the chamber and the guide hole, respectively. A rectangular guide groove is provided at the end of the transmission spindle near the guide hole. Drive arms are symmetrically arranged on the outer periphery of the transmission spindle. A swing plate is hinged to the top of the chamber, and a cotton guide plate is fixed to the end of the swing plate.
[0011] A further improvement is that the positioning adjustment assembly includes a spring, a guide sleeve, a transmission spindle, an adjusting handwheel, a rectangular guide rod, a positioning pin group, an angle scale, and an operating handle. The guide sleeve is connected to the base via the spring. The transmission spindle is rotatably connected to the guide sleeve and fixedly connected to the adjusting handwheel. The rectangular guide rod is located near the main shaft end of the transmission spindle. The positioning pin group and the positioning hole group form a selective insertion fit. The positioning pin group is evenly distributed along the circumferential edge of the adjusting handwheel. The operating handle is axially fixed to the adjusting handwheel.
[0012] A further improvement is that a wing plate is provided near the feed end of the guide plate, and the working surface of the wing plate forms an adaptive sealing contact with the inner wall of the feed end of the base.
[0013] A further improvement is that the outer side of the positioning hole group is provided with an angle mark, which is set in a cyclic scale of 0°-2°-3°-4°.
[0014] 3. Beneficial effects:
[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0016] (1) Precise angle control and dynamic arc surface generation: A multi-level angle adjustment mechanism (0° / 2° / 3° / 4°) is adopted. Through the coordinated action of the transmission spindle and the drive arm, the feeding table forms a continuously gradually changing "√"-shaped composite arc surface. This structure breaks through the limitations of traditional planar feeding and realizes the optimization of material transmission dynamics. When the fiber material comes into contact with the arc surface, its natural downward angle increases by 15%-25% compared with the planar structure, effectively eliminating dead corners of material accumulation and improving the smoothness of feeding by about 30%.
[0017] (2) Path extension and enhanced fiber adaptability: The arc-shaped design extends the material transport path by 2.3-3.8 times compared to the traditional planar design (calculated based on the same cotton feeding width), significantly extending the fiber combing time. This allows the fiber to stay in the cotton feeding stage for 1.8-2.5 times longer than the traditional structure, making it particularly suitable for processing raw materials such as long-staple cotton (fiber length ≥35mm) and special animal fibers that require extended combing time. Under the premise of ensuring combing quality, the applicable fiber length range of the equipment is expanded to the 25-50mm range.
[0018] (3) Intelligent production and efficiency improvement: The angle can be switched steplessly by operating the handle (adjustment accuracy ±0.5°), completely eliminating the need for manual cotton stuffing. This increases the raw cotton processing efficiency by 32.6% and reduces downtime caused by manual intervention by about 75%, significantly improving the overall equipment efficiency (OEE) index.
[0019] (4) Process compatibility and energy consumption optimization: The multi-level angle adjustment function enables a single unit to be compatible with the processing needs of different fiber varieties such as cotton, linen, and chemical fiber, and the process switching time is shortened to within 2 minutes. The natural gravity material distribution effect generated by the arc structure reduces the motor load by 18%-22% compared with the traditional screw feeding method, achieving the dual goals of energy saving and flexible production.

[0038] Please see Figures 1-5 An adjustable cotton feeding device for a raw cotton impurity analyzer, the specific structural components of which include:
[0039] The main body 1 of the raw cotton impurity analyzer is equipped with a combing roller 2, and the front feeding area is equipped with an arc-shaped cotton feeding platform 3 and a roller shaft 4.
[0040] The arc-shaped cotton feeding platform 3 includes modules such as a base 31, an angle adjustment mechanism 33, and a positioning adjustment component 36.
[0041] The angle adjustment mechanism 33 drives the swing plate 334 and the cotton guide plate 335 to rotate through the transmission main shaft 331 and the drive arm 333, thereby achieving an angle adjustment of 0°-4°.
[0042] The positioning adjustment component 36 achieves angle locking and releasing through spring 361, guide sleeve 362, and transmission spindle 363.
[0043] I. Specific structural fit and transmission steps include:
[0044] 1. Angle Adjustment Procedure
[0045] Unlocking phase: The operator pulls the operating handle 368 on the outside of the base 31 outward, which drives the transmission spindle 363 to move axially, so that the positioning pin group 366 is released from the limitation of the positioning hole group 35, and at the same time stretches the spring 361.
[0046] Angle setting: Rotate the operating handle 368, and transmit torque to the transmission main shaft 331 through the rectangular guide rod 365. The drive arm 333 rotates with the main shaft and pushes the swing plate 334 to swing, thereby driving the cotton guide plate 335 to rotate to the target angle, such as 2° or 3°.
[0047] Locking phase: Release the operating handle 368, the spring 361 rebounds and pushes the guide sleeve 362, so that the positioning pin group 366 is re-inserted into the corresponding position of the positioning hole group 35, and the angle is fixed.
[0048] 2. Coordinated transmission structure
[0049] The rectangular guide groove 332 of the transmission spindle 331 and the rectangular guide rod 365 form a key connection to ensure efficient torque transmission.
[0050] The drive arms 333 are symmetrically arranged on both sides of the transmission main shaft 331 to balance the force and improve rotational stability.
[0051] II. Installation Process
[0052] 1. Base fixing
[0053] The base 31 is fixed to the feeding area of the main body 1 of the raw cotton impurity analyzer with bolts, ensuring that the feeding end of the arc-shaped cotton feeding platform 3 is aligned with the roller shaft 4.
[0054] 2. Angle adjustment mechanism assembly
[0055] The swing plate 334 is hinged to the rotating shaft at the top of the base 31, and the cotton guide plate 335 is fixed to the swing plate 334 by bolts.
[0056] Install the drive spindle 331 into the cavity 32 of the base 31, ensuring that both ends are embedded in the guide holes 34 respectively.
[0057] 3. Installation of positioning adjustment components
[0058] Spring 361 is fitted into guide sleeve 362, and then the two are inserted together into guide hole 34 on side wall of base 31. Subsequently, spring 361 is welded to side wall of base 31.
[0059] Assemble the transmission spindle 363 into the guide sleeve 362, weld or thread the adjusting handwheel 364, and fix the rectangular guide rod 365 to its side.
[0060] The locating pin group 366 is distributed around the outer edge of the adjusting handwheel 364, and it matches the locating hole group 35.
[0061] 4. Debugging and Calibration
[0062] Rotate the operating handle 368 to each preset angle of 0°, 2°, 3°, and 4° to verify the stopping stability of the cotton guide plate 335 and the accuracy of the angle mark 37.
[0063] Adjust the preload of spring 361 to ensure smooth insertion and removal of the locating pin assembly 366 and the locating hole assembly 35, and reliable locking.
