Description

Technical Field

[0001] This utility model relates to the field of carding machine technology, specifically to a carding machine combing device. Background Technology

[0002] In the spinning preparation process of the textile industry, the carding machine plays a crucial role. Its core function is to thoroughly comb the opened fiber bundles, separating them into single fibers and further removing residual fine impurities and short fibers, thereby forming a uniform fiber web (i.e., sliver), laying a solid foundation for the subsequent yarn quality. This process is mainly completed by the carding device of the carding machine. Among them, the high-speed rotating licker-in roller assembly, as the pre-carding unit, has densely arranged carding teeth on its surface that interact intensely with the fiber material, making it a key component for achieving efficient carding and impurity removal.

[0003] In existing technologies, the common licker-in roller structure often integrates the combing teeth with the roller body using an integral design or irreversible methods such as welding. While this structure provides good structural strength initially, under long-term high-speed, high-load operation, the combing teeth are prone to chipping, bending, or breaking due to direct impact with hard impurities or metallic foreign objects. Once individual or partial teeth are damaged, the overall combing effect is severely affected, leading to a significant decrease in cotton web quality and problems such as cloudiness and increased neps. However, because the combing teeth and roller body are integrated, users cannot replace damaged teeth individually; the entire licker-in roller assembly must be disassembled and discarded before installing a new one. This maintenance method not only incurs high component replacement costs and increases production downtime, reducing equipment utilization, but also contradicts the current industrial production philosophy of pursuing cost reduction, efficiency improvement, and sustainable development. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a carding machine carding device that solves the problem that the carding teeth and the licker-in roller are an integral structure, and that partial damage requires replacement of the entire licker-in roller, resulting in high maintenance costs and low efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carding machine combing device, comprising a roller body, with flange plates provided at both ends of the roller body's outer edges, and a plurality of positioning holes equidistantly arranged on one side of the flange plates. A plurality of limiting strips corresponding sequentially to each positioning hole are snapped onto the outside of the roller body between the two flange plates. After the limiting strips are assembled on the roller body, their cross-sections form a ring, and the limiting strips are densely covered with combing teeth. Both ends of the roller body are provided with quick-release pressing parts for removing the limiting strips, and both ends of the limiting strips are provided with locking parts.

[0006] Preferably, the locking component includes a slot on the end face of the limiting strip, and a locking shaft adapted to the positioning hole is slidably installed in the slot. One end of the locking shaft is connected to the inner side of the slot by a limiting spring.

[0007] Preferably, the end face of the retaining shaft away from the limiting spring is a beveled structure. When the retaining bar is inserted between the two flange plates on the roller body, the beveled surface of the retaining shaft presses against the side of the flange plate.

[0008] Preferably, the quick-release pressing component includes a T-shaped shaft connected to the center of the roller end face. A limit ring is laterally slidably installed on the outside of the T-shaped shaft, and a return spring is also sleeved on the outside of the T-shaped shaft. A protrusion is provided on the upper side of the limit ring, and a top shaft that matches the positioning hole is provided on one side of the upper end of the protrusion, so that when the flange plate rotates, each positioning hole on the flange plate passes through the top shaft in sequence.

[0009] Preferably, a T-shaped guide shaft is laterally slidably inserted on one side of the convex strip, and an annular T-groove adapted to the T-shaped guide shaft is provided on the end face of the roller body. One end of the T-shaped guide shaft is disposed in the annular T-groove and slidably connected to the roller body.

[0010] Preferably, the upper part of the roller body is symmetrically provided with two grooves, and an ejector spring is connected in the groove, with the upper end of the ejector spring extending out of the groove.

[0011] This utility model provides a carding machine carding device, which has the following advantages compared with the prior art: This carding machine's carding device uses rotating ribs at both ends of the roller to align the top shaft on the ribs with the positioning hole. Under the action of a return spring, the top shaft smoothly inserts into the hole, squeezing the retaining shaft and causing it to retract. At this point, the ejector spring pushes the limiting strip upwards, disengaging the retaining shaft from the positioning hole. This effectively avoids the inconvenience caused by the retaining shaft accidentally getting stuck in the positioning hole during disassembly, and also achieves quick and damage-free disassembly. When installing a new limiting strip, the inclined guide structure on the end face of the retaining shaft guides the retaining strip, causing it to automatically retract under pressure during insertion. Once in place, the limiting spring precisely pushes the retaining shaft into the positioning hole, completing automatic locking. The entire process requires no auxiliary tools and can be efficiently completed by a single person without replacing the entire licker-in roller, significantly improving the efficiency and safety of replacement operations while reducing maintenance costs. It possesses good industrial application value and promising prospects for widespread adoption. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-2 A carding machine combing device includes a roller body 1. Both ends of the roller body 1 are provided with flange plates 2. One side of the flange plates 2 is provided with a plurality of positioning holes 3 at equal intervals. The outside of the roller body 1 is located between the two flange plates 2 and is connected with a plurality of limiting strips 4 corresponding to each positioning hole 3 in sequence. After the limiting strips 4 are assembled on the roller body 1, their cross-sections form a ring. The limiting strips 4 are densely covered with combing teeth 5. Both ends of the roller body 1 are provided with quick-release pressing parts 6 for removing the limiting strips 4. Both ends of the limiting strips 4 are provided with locking parts 7.

[0016] Please see Figures 2-3 In this embodiment of the utility model, the card 7 includes a slot 71 disposed on the end face of the limiting strip 4. A card shaft 72 adapted to the positioning hole 3 is slidably installed in the slot 71. One end of the card shaft 72 is connected to the inner side of the slot 71 by a limiting spring 73.

[0017] Please see Figures 2-3 In this embodiment of the present invention, the end face of the retaining shaft 72 away from the limiting spring 73 is a sloping structure. When it is inserted between the two flange plates 2 on the roller body 1 by the limiting strip 4, the sloping surface of the retaining shaft 72 presses against the side of the flange plate 2.

[0018] Please see Figure 2 and Figure 4In this embodiment of the present invention, the quick-release pressing component 6 includes a T-shaped shaft 61 connected to the center of the end face of the roller body 1. A limiting ring 62 is slidably mounted on the outside of the T-shaped shaft 61, and a return spring 63 is also sleeved on the outside of the T-shaped shaft 61. A protrusion 64 is provided on the upper side of the limiting ring 62, and a top shaft 65 adapted to the positioning hole 3 is provided on one side of the upper end of the protrusion 64. When the flange plate 2 rotates, each positioning hole 3 on the flange plate 2 passes through the top shaft 65 in sequence. A ball is inserted into one end of the top shaft 65 and rotated. When the limiting strip 4 is pushed upward, the retaining shaft 72 will also move upward, and the inclined surface of the retaining shaft 72 will contact the ball on the top shaft 65. Under the rotation of the ball, the limiting strip 4 is more easily pushed out.

[0019] Please see Figure 2 and Figure 4 In this embodiment of the present invention, a T-shaped guide shaft 66 is also laterally slidably inserted on one side of the protrusion 64. An annular T-groove 13 adapted to the T-shaped guide shaft 66 is provided on the end face of the roller body 1. One end of the T-shaped guide shaft 66 is provided in the annular T-groove 13 and is slidably connected to the roller body 1. The T-shaped guide shaft 66 plays a role in limiting and guiding the displacement of the protrusion 64. The annular T-groove 13 facilitates the rotation of the protrusion 64 so that the top shaft 65 on the protrusion 64 is aligned with the corresponding positioning hole 3.

[0020] Please see Figure 2 In this embodiment of the present invention, two grooves 11 are symmetrically arranged on the upper part of the roller body 1, and an ejector spring 12 is connected in the groove 11, with the upper end of the ejector spring 12 extending out of the groove 11.

[0021] Working principle: When the comb teeth 5 on the limiting strip 4 break and need to be replaced, rotate the protrusions 64 at both ends of the roller body 1 so that the top shaft 65 on the protrusion 64 aligns with the corresponding positioning hole 3. Then, under the elasticity of the return spring 63, press the protrusion 64 so that one end of the top shaft 65 is inserted into the positioning hole 3 on the flange plate 2, squeezing the retaining shaft 72 on the retaining piece 7. Under the elasticity of the limiting spring 73, as the top shaft 65 is squeezed, the retaining shaft 72 will slide in the groove 71. When the retaining shaft 72 is completely removed from the positioning hole 3 on the flange plate 2, under the elasticity of the ejector spring 12, the ejector spring 12 will push the limiting strip 4 upward, moving the retaining shaft 72 above the positioning hole 3, preventing further damage during disassembly. During disassembly, the retaining shaft 72 gets stuck in the positioning hole 3, which makes disassembly inconvenient. Finally, the limiting strip 4 can be removed to complete the disassembly. Then, a new limiting strip 4 is installed and placed between the two flange plates 2 on the roller body 1. Since one end face of the retaining shaft 72 is a beveled structure, when the limiting strip 4 is placed between the two flange plates 2, the beveled end face of the retaining shaft 72 will press against the side of the flange plate 2. As the limiting strip 4 is pressed down, the retaining shaft 72 gradually slides into the groove 71. When the limiting strip 4 is fully inserted, the retaining shaft 72 corresponds exactly to the position of the positioning hole 3 on the flange plate 2. At this time, the limiting spring 73 resets the retaining shaft 72, and the retaining shaft 72 will be inserted into the positioning hole 3, completing the installation and replacement of the limiting strip 4.

[0022] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
