Description

Technical Field

[0001] This application relates to the field of textile equipment technology, and in particular to a cotton feeding device and a carding machine. Background Technology

[0002] The connection between the feed roller and the cotton box in a carding machine is a flat cotton-feeding plate with an inclined angle. The cotton layer enters the feed roller from top to bottom through the cotton-feeding plate by its own weight and the pushing force of the subsequent cotton layers, and then enters the subsequent carding zone. After long-term operation, the oil on the fibers causes a large oil film to appear on the surface of the cotton-feeding plate. The oil film causes the cotton layer to experience greater resistance and cannot be fed evenly and smoothly, resulting in uneven sliver weight, affecting yarn properties and production efficiency. In particular, for flat cotton-feeding plates with a small inclined angle, the cotton layer moves on the cotton-feeding plate and accumulates and bulges due to frictional resistance, making it impossible to complete the cotton feeding process, which greatly affects the cotton feeding efficiency. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a cotton feeding device and a carding machine that can reduce the movement resistance of the cotton layer, facilitate the movement of the cotton layer, and effectively improve the cotton feeding efficiency.

[0004] This application provides the following technical solution: In a first aspect, embodiments of this application provide a cotton feeding device, the cotton feeding device comprising: A cotton-flowing board has a first guide section, the upper end of the first guide section has at least two protrusions, the protrusions extend along a first direction, and the at least two protrusions are spaced apart in a second direction; wherein the first direction and the second direction intersect, and the top of the at least two protrusions forms a first bearing end face.

[0005] In some embodiments of the first aspect, the first direction is parallel to the cotton conveying direction, and the second direction is perpendicular to the first direction.

[0006] In some embodiments of the first aspect, the cotton conveying plate further has a second guide section, the upper end of which has a second bearing end face; in the cotton conveying direction, the second guide section and the first guide section are arranged sequentially, and the first bearing end face and the second bearing end face are smoothly transitioned; In particular, the height of the second bearing end face gradually decreases in the direction close to the first guide segment.

[0007] In some embodiments of the first aspect, the first guide segment and the second guide segment are detachably connected.

[0008] In some embodiments of the first aspect, the first guide segment is configured as a corrugated plate.

[0009] In some embodiments of the first aspect, the cotton feeding device further includes: At least one cotton feeding drive is provided upstream of the cotton conveying plate in the cotton conveying direction. The cotton feeding drive includes a cotton feeding drive part and a pair of cotton feeding rollers. The pair of cotton feeding rollers are arranged side by side. The cotton feeding drive is connected to at least one of the cotton feeding rollers. The cotton feeding drive can drive the cotton feeding rollers to rotate in order to convey the cotton layer passing between the pair of cotton feeding rollers.

[0010] In some embodiments of the first aspect, the number of the cotton feeding drive is two, with one of the cotton feeding drive located upstream of the cotton flow plate and the other of the cotton feeding drive located downstream of the cotton flow plate in the cotton conveying direction.

[0011] In some embodiments of the first aspect, one of a pair of feeding rollers downstream of the cotton-feeding plate is a licker roller.

[0012] Secondly, embodiments of this application also provide a carding machine, the carding machine including the cotton feeding device described in any of the above embodiments. The embodiments of this application have the following advantages: This application provides a cotton feeding device. The first guide section of the cotton feeding plate has at least two protrusions extending along a first direction (such as the direction of cotton layer movement). These protrusions are spaced apart in a second direction (a transverse direction perpendicular to the first direction) to form a discontinuous support structure. The top of each protrusion forms a first bearing end face, and the cotton layer contacts only through the top of the protrusion, significantly reducing the actual contact area between the cotton layer and the surface of the cotton feeding plate, thereby reducing frictional resistance. The extension direction of the protrusions is consistent with the direction of cotton layer movement. Under the action of gravity and subsequent thrust, the cotton layer slides along the protrusions. Simultaneously, the spacing between the protrusions allows airflow to pass through or disperse the cotton layer pressure, preventing cotton layer accumulation. Furthermore, adjacent protrusions form grooves, which can separate cotton from impurities. Impurities and short fibers in the fiber layer fall into the grooves of the cotton feeding plate as the cotton layer moves. Similarly, even if an oil film forms on the surface of the cotton feeding plate due to fiber oiling, the protrusions can reduce the adhesion resistance of the oil film to the cotton layer, ensuring smooth movement of the cotton layer.

[0013] Therefore, by reducing the contact area through the protrusions, the friction between the cotton layer and the feed roller is significantly reduced, especially improving the difficulty of cotton layer sliding when the inclination angle is small. This prevents the cotton layer from bulging or stagnating due to excessive resistance, ensuring continuous and uniform entry of the cotton layer into the feed roller, improving sliver weight consistency and yarn quality. The protrusions also reduce the negative impact of the oil film on cotton layer movement, extending equipment maintenance cycles and improving production efficiency.

[0023] In related technologies, the connection between the cotton feeding component and the cotton box of a carding machine is a flat cotton-feeding plate 200 with an inclined angle. The cotton layer enters the inlet of the feeding roller from top to bottom through the cotton-feeding plate 200 by its own weight and the thrust of the subsequent cotton layer. After long-term operation, the oil on the fibers causes a large oil film to appear on the surface of the cotton-feeding plate 200. The oil film causes the cotton layer to experience greater resistance and cannot be fed evenly and smoothly, resulting in uneven sliver weight, affecting yarn properties and production efficiency. In particular, for flat cotton-feeding plates 200 with a small inclined angle, the cotton layer moves on the cotton-feeding plate 200 and accumulates and bulges due to frictional resistance, making it impossible to complete the cotton feeding process, which greatly affects the cotton feeding efficiency.

[0024] like Figure 1 and Figure 2 As shown, in order to solve the above-mentioned technical problems, this application provides a cotton feeding device, which includes a cotton feeding plate 200. The cotton feeding plate 200 has a first guide section 220. The upper end of the first guide section 220 has at least two protrusions 221. The protrusions 221 extend along a first direction, and the at least two protrusions 221 are spaced apart in a second direction. The first direction and the second direction intersect each other, and the top of the at least two protrusions 221 forms a first bearing end face.

[0025] In these embodiments, the first direction is the longitudinal direction of the cotton-flowing board 200, and the second direction is the transverse direction of the cotton-flowing board 200, as an example.

[0026] This utility model provides a cotton feeding device to improve the movement resistance of the cotton layer on the cotton feeding plate 200, thereby improving cotton feeding efficiency and cotton sliver quality. The cotton feeding device includes a cotton feeding plate 200, which has a first guide section 220, and at least two protrusions 221 are provided at the upward-facing end of the first guide section 220.

[0027] The protrusions 221 extend along a first direction, and the at least two protrusions 221 are arranged at intervals along a second direction. The first direction intersects the second direction and can be optionally arranged perpendicularly to form an effective support and guiding structure during cotton layer conveying.

[0028] Furthermore, at least two protrusions 221 have a first bearing end face formed on their tops. The first bearing end face is used to contact the cotton layer to reduce the contact area between the cotton layer and the cotton-feeding plate 200, thereby reducing frictional resistance. The protrusions 221 can be strip-shaped structures, and their cross-sectional shape can be rectangular, semi-circular, or trapezoidal, preferably semi-circular, to reduce resistance to the cotton layer and prevent the cotton fibers from being scratched.

[0029] The cotton feeding plate 200 is inclined, and its inclination angle can be adjusted according to the actual cotton feeding process requirements, preferably between 10° and 30°. The smaller the inclination angle of the cotton feeding plate, the more significant the effect of this invention compared to traditional structures, namely, it can reduce the movement resistance of the cotton layer, facilitate the movement of the cotton layer, and effectively improve the cotton feeding efficiency. The first guide section 220 is located in the upper region of the cotton feeding plate 200, that is, the transition region before the cotton layer begins to enter the inlet of the feeding roller. In this region, due to the low cotton layer speed, accumulation and frictional resistance are easily generated. Therefore, the protrusion 221 effectively improves the cotton feeding performance in this region.

[0030] In actual use, after the cotton layer is output from the cotton box, it first contacts the second guide section 210 of the cotton-feeding plate 200. Under the action of gravity and the thrust of subsequent cotton layers, the cotton layer moves along the cotton-feeding plate 200 towards the first guide section 220. When the cotton layer passes the protrusion 221, it only contacts the first bearing end face, reducing the contact area with the cotton-feeding plate 200, thereby effectively reducing frictional resistance, preventing the cotton layer from accumulating or bulging during movement, and improving the uniformity and continuity of cotton feeding.

[0031] Furthermore, the top surface of the protrusion 221 can be smoothed or coated with an anti-stick coating, such as a Teflon coating, to further reduce friction between the cotton layer and the cotton board 200, prevent the oil on the fibers from forming an oil film on the surface, and thus avoid the problem of poor sliding of the cotton layer caused by the oil film.

[0032] Furthermore, the number of protrusions 221 can be set to two, three, or more as needed, and they are evenly spaced along the second direction to provide a more stable support effect. The height of the protrusions 221 is generally controlled between 5 and 15 mm.

[0033] In summary, by setting multiple protrusions 221 extending in the first direction and spaced apart in the second direction in the upper region of the cotton feeding plate 200, the cotton layer only contacts the top of the protrusions 221 during movement, thereby significantly reducing frictional resistance, avoiding cotton layer accumulation, improving cotton feeding efficiency and cotton sliver quality, and thus improving yarn uniformity and production efficiency.

[0034] In some alternative embodiments, similar raised structures can be provided in other areas of the cotton conveying plate 200 to further optimize the conveying performance of the cotton layer. Furthermore, the raised portion 221 can also be removable for easy cleaning and maintenance.

[0035] In other words, the first guide section 220 of the cotton-flowing board 200 is provided with at least two protrusions 221 extending along a first direction (such as the direction of cotton layer movement). These protrusions 221 are spaced apart in a second direction (a transverse direction perpendicular to the first direction) to form a discontinuous support structure. The top of the protrusion 221 constitutes a first bearing end face. The cotton layer is in contact only through the top of the protrusion 221, which significantly reduces the actual contact area between the cotton layer and the surface of the cotton-flowing board 200, thereby reducing frictional resistance. The extension direction of the protrusion 221 is consistent with the direction of cotton layer movement. Under the action of gravity and subsequent thrust, the cotton layer slides along the protrusion 221. At the same time, the interval between the protrusions 221 allows airflow to pass through or disperse the cotton layer pressure, preventing cotton layer accumulation. Furthermore, adjacent protrusions 221 form grooves, which can play a role in separating cotton and impurities. Impurities and short fibers in the fiber layer fall into the grooves of the cotton-flowing board 200 as the cotton layer moves. Similarly, even if an oil film is formed on the surface of the cotton-flowing board 200 due to the fiber oiling agent, the protrusion 221 can reduce the adhesion resistance of the oil film to the cotton layer, ensuring smooth movement of the cotton layer.

[0036] Therefore, by reducing the contact area through the protrusion 221, the friction between the cotton layer and the cotton feeding plate 200 is significantly reduced, especially improving the difficulty of cotton layer sliding when the inclination angle is small. This prevents the cotton layer from bulging or stagnating due to excessive resistance, ensuring that the cotton layer enters the feed roller continuously and evenly, improving sliver weight consistency and yarn quality. The protrusion 221 also reduces the negative impact of oil stains on cotton layer movement, extending equipment maintenance cycles and improving production efficiency.

[0037] In some embodiments, the first direction is parallel to the cotton conveying direction, and the second direction is perpendicular to the first direction.

[0038] In these embodiments, the first direction is parallel to the cotton conveying direction, that is, the direction in which the cotton layer is conveyed from the cotton box to the feeding roller. The second direction is perpendicular to the first direction, that is, multiple protrusions 221 are arranged in the width direction of the cotton layer to form support points distributed laterally at intervals.

[0039] By extending the protrusions 221 along the cotton conveying direction, the contact length between the cotton layer and the protrusions 221 can be effectively extended, thereby improving support stability. At the same time, since multiple protrusions 221 are distributed at intervals in the width direction (i.e., the second direction) of the cotton layer, the force on the cotton layer is more uniform, avoiding the cotton layer from bulging or shifting due to excessive local resistance.

[0040] In some embodiments, the cotton conveying plate 200 also has a second guide section 210, and the upward end of the second guide section 210 has a second bearing end face; in the cotton conveying direction, the second guide section 210 and the first guide section 220 are arranged in sequence, and the first bearing end face and the second bearing end face are smoothly transitioned; wherein, in the direction close to the first guide section 220, the height of the second bearing end face gradually decreases.

[0041] In these embodiments, in the cotton conveying direction, the second guide section 210 is located upstream of the first guide section 220 (i.e., on the side near the cotton feed roller 110). The upward-facing end of the second guide section 210 is provided with a second bearing end face for receiving the cotton layer transitioning from the cotton box 300.

[0042] The second bearing end face and the first bearing end face transition smoothly in the cotton conveying direction, ensuring that the cotton layer can smoothly enter the first guide section 220 from the second guide section 210, avoiding resistance or accumulation due to structural abrupt changes.

[0043] Furthermore, the height of the second bearing end face gradually decreases in the direction close to the first guide section 220, that is, when transitioning from the second guide section 210 to the first guide section 220, the height of the bearing surface gradually decreases, forming an inclined transition surface. For example, the second bearing end face is an arc-shaped surface.

[0044] The gradual decrease in height helps the cotton layer slide smoothly from the second guide section 210 into the first guide section 220; by changing the height and cooperating with the first bearing end face, the pressure and contact area between the cotton layer and the cotton-feeding board 200 are reduced.

[0045] In some embodiments, the first guide segment 220 and the second guide segment 210 are detachably connected.

[0046] In these embodiments, the first guide segment 220 and the second guide segment 210 are connected by a detachable connection structure, such as a snap-fit ​​connection, screw connection, magnetic connection, or plug-in structure. This connection method ensures both a stable connection and load-bearing function between the two segments, while also facilitating disassembly, replacement, or cleaning.

[0047] Specifically, the lower end of the second guide section 210 is fixedly connected to or integrally formed with the main body of the cotton conveying plate 200, while its upper end is detachably connected to the lower end of the first guide section 220 through a connector. The first bearing end face and the second bearing end face smoothly transition in the cotton conveying direction, maintaining good surface continuity and functionality even in the detachable state.

[0048] The advantages of using a detachable connection structure are as follows: During prolonged use, the oil in the cotton layer may form oil stains on the surface of the cotton-feeding plate 200, affecting the sliding performance of the cotton layer. The first guide section 220 and the second guide section 210 are designed as detachable structures to facilitate cleaning of the protrusion 221 and its bearing end face, restoring its low-friction performance. The first guide section 220 with different structural parameters (such as protrusions 221 of different heights, numbers, or shapes) can be replaced according to different cotton layer thicknesses, cotton feeding speeds, or fiber types to adapt to different process requirements. If one section of the guide section is worn or damaged, only that part needs to be replaced, without replacing the entire cotton feeding plate 200, thus reducing maintenance costs.

[0049] In one exemplary embodiment, the lower end of the first guide section 220 is provided with a connecting hole, and the upper end of the second guide section 210 is provided with a corresponding positioning post. The positioning post is inserted into the connecting hole to achieve plug-in fixation. In another embodiment, the two are fastened together by screws passing through the positioning hole. Magnetic connection can also be used, which is suitable for occasions that require frequent disassembly and assembly.

[0050] Regardless of the connection method used, a smooth transition between the first and second bearing end faces should be ensured to prevent jamming or increased resistance during the cotton layer conveying process due to the connection structure.

[0051] In some embodiments, the first guide section 220 is configured as a corrugated plate.

[0052] In these embodiments, the first guide section 220 employs a corrugated plate that extends along the cotton conveying direction and has a periodic undulation on its surface, forming multiple protrusions 221 and recessed areas. The corrugated plate helps reduce the contact area between the cotton layer and the cotton feeding plate 200, thereby reducing frictional resistance, while also better guiding the cotton layer evenly into the feed roller inlet.

[0053] The corrugations on the corrugated board can be regular sine waves, trapezoidal waves, or other suitable shapes, preferably sine waves, because this shape can minimize damage to cotton fibers while ensuring good support.

[0054] The height and spacing of the corrugations can be adjusted according to the actual application requirements. Generally speaking, the height of the corrugations is controlled between 7mm and 15mm, while the spacing is determined according to the width of the fabric, usually ranging from 10mm to 30mm.

[0055] As mentioned earlier, in the cotton conveying direction, the second guide section 210 is located upstream of the first guide section 220. The upward-facing end of the second guide section 210 is provided with a second bearing end face for receiving the cotton layer transitioning from the cotton box 300. The second bearing end face smoothly transitions to the first bearing end face of the first guide section 220 (corrugated plate) in the cotton conveying direction, ensuring that the cotton layer can smoothly enter the first guide section 220 from the second guide section 210, avoiding resistance or accumulation due to abrupt structural changes.

[0056] Specifically, when the first guide section 220 uses a corrugated plate, the design of the second bearing end face needs to consider its connection with the corrugated plate to ensure a natural and smooth transition between the two, preventing any jamming during the movement of the cotton layer. For example, the second bearing end face can be designed as a gradually transitioning arc surface, gradually transitioning to the first crest or trough of the corrugated plate to achieve a seamless connection. For instance, the second bearing end face and the first bearing end face are connected in the first direction, with the second bearing end face overlapping the crest of the first bearing end face.

[0057] In some embodiments, the cotton feeding device further includes at least one cotton feeding drive 100. In the cotton conveying direction, a cotton feeding drive 100 is provided upstream of the cotton conveying plate 200. The cotton feeding drive 100 includes a cotton feeding drive part and a pair of cotton feeding rollers 110. The pair of cotton feeding rollers 110 are arranged side by side. The cotton feeding drive 100 and at least one cotton feeding roller 110 are connected. The cotton feeding drive 100 can drive the cotton feeding rollers 110 to rotate in order to convey the cotton layer passing between the pair of cotton feeding rollers 110.

[0058] In these embodiments, the cotton feeding device further includes at least one cotton feeding drive 100, which is located upstream of the cotton delivery plate 200, i.e., at one end of the cotton layer conveying path closer to the cotton box. The cotton feeding drive 100 is used to actively convey the cotton layer, ensuring that it enters the first guide section 220 of the cotton delivery plate 200 smoothly and continuously.

[0059] The cotton feeding drive unit 100 includes: Cotton feeding drive unit: such as a motor or servo motor, used to provide power; A pair of cotton feeding rollers 110 are arranged side by side in the cotton layer conveying path, forming a gap between them for the cotton layer to pass through; The cotton feeding drive unit is connected to at least one cotton feeding roller 110 and is used to drive the cotton feeding roller 110 to rotate, thereby driving the cotton layer to be conveyed forward.

[0060] In these embodiments, the two feeding rollers 110 are a driving roller and a driven roller, respectively, wherein the driving roller is connected to the feeding drive unit, and the driven roller is rotatably mounted on the support and cooperates with the driving roller to clamp the cotton layer; in other embodiments, both feeding rollers 110 are driving rollers and are driven by the same drive unit to improve the synchronicity and stability of the conveying.

[0061] In the cotton conveying direction, the cotton feeding drive 100 is located upstream of the cotton flow plate 200. After the cotton layer is output from the cotton feeding drive 100, it enters the second guide section 210 and the first guide section 220 of the cotton flow plate 200 and is then conveyed backward.

[0062] In addition, the conveying speed of the cotton feeding drive 100 is adjustable to match the feeding speed of the subsequent cotton feeding roller, ensuring that the cotton layer maintains uniform tension and continuous feeding during the conveying process, and avoiding problems such as cotton layer breakage or accumulation caused by speed mismatch.

[0063] In some embodiments, there are two cotton feeding drives, one of which is located upstream of the cotton conveying plate 200 and the other is located downstream of the cotton conveying plate 200 in the cotton conveying direction.

[0064] In these embodiments, the cotton feeding device includes two cotton feeding drives 100, wherein: The first cotton feeding drive unit 100 is located upstream of the cotton conveying plate 200, that is, the initial conveying section after the cotton layer is output from the cotton box; The second cotton feeding drive component 100 is located downstream of the cotton flow plate 200, that is, in the transition section after the cotton layer leaves the cotton flow plate 200 and before entering the cotton feeding roller, or directly integrated at the inlet of the cotton feeding roller.

[0065] Each cotton feeding drive unit 100 includes: Cotton feeding drive unit: such as a motor or servo motor, used to provide power; A pair of cotton feeding rollers 110: arranged side by side, used to hold and convey the cotton layer; The cotton feeding drive unit is connected to at least one cotton feeding roller 110 and is used to drive the cotton feeding roller 110 to rotate, thereby driving the cotton layer to be conveyed forward.

[0066] In some embodiments, the feeding rollers 110 of the two feeding drive units 100 can be synchronized or their speeds matched and adjusted by a control system to ensure that the cotton layer has uniform tension and runs smoothly during the conveying process, and to avoid stretching deformation or breakage caused by speed differences.

[0067] The first cotton feeding drive 100 is mainly used to actively pull the cotton layer out of the cotton box and stably transport it to the first guide section 220 of the cotton feeding plate 200, so as to prevent poor cotton feeding caused by insufficient weight of the cotton layer or excessive frictional resistance. The second cotton feeding drive component 100 is used to continue to actively pull the cotton layer after it leaves the cotton flow plate 200, ensuring that it smoothly enters the cotton feeding roller inlet and improving the continuity and uniformity of the overall cotton feeding.

[0068] By setting cotton feeding drive components 100 at the upstream and downstream of the cotton feeding plate 200, segmented control and coordinated driving of the cotton layer conveying process can be realized. Especially when the cotton layer is thin, the fiber is long, or the frictional resistance is large, the cotton feeding efficiency and cotton sliver quality can be significantly improved.

[0069] In some embodiments, this application also provides a carding machine, which includes the cotton feeding device described in any of the above embodiments.

[0070] Since the aforementioned cotton feeding device has the aforementioned technical effects, the carding machine that includes the aforementioned cotton feeding device should have the same technical effects, which will not be elaborated here.

[0071] In the cotton conveying direction, after the cotton layer is output from the cotton box 300, it is driven by the first cotton feeding drive 100, guided by the cotton flow plate 200, and then driven by the second cotton feeding drive 100 before entering the subsequent carding zone.

[0072] In some embodiments, one of a pair of feed rollers 110 at the entrance of the subsequent carding zone is a licker-in roller 120.

[0073] In these embodiments, a pair of feed rollers 110 are provided at the entrance of the subsequent carding zone, wherein: One is a licker-in roller 120, whose surface is provided with needle cloth or barbed structure to enhance the ability to grasp the cotton layer and also has a pre-carding function; The other is a smooth roller or a rubber roller, which works with the licker-in roller 120 to form a conveying channel for holding the cotton layer.

[0074] The licker-in roller 120 can be connected to the cotton feeding drive 100 and rotated by the drive to actively pull the cotton layer forward. The licker-in roller 120 not only improves the gripping force of the cotton feeding roller 110 on the cotton layer, but also slightly loosens the cotton layer during the conveying process, which helps the subsequent cotton feeding roller to evenly grip and comb the cotton layer.

[0075] In actual operation: The licker-in roller 120 enhances the friction between itself and the cotton layer through its needle-cloth structure, preventing the cotton layer from slipping or breaking during the conveying process; the smooth roller or rubber roller plays the role of pressing the cotton layer and stabilizing the conveying; the combination of the two can effectively improve the stability of the cotton feeding process, especially when the cotton layer is thin, the fiber is long, or the oil content is high, the effect of the licker-in roller 120 is particularly obvious.

[0076] As previously mentioned, in some embodiments, the cotton feeding device includes two cotton feeding drive components 100, respectively disposed between the front cotton box 300 and the rear carding zone inlet. Wherein: The cotton feeding drive 100 in the front cotton box 300 is used to smoothly output the cotton layer from the cotton box; The entrance to the carding zone at the rear also includes a licker-in roller 120, which is used to actively pull and pre-treat the cotton layer.

[0077] Through the coordinated control of the upper and lower cotton feeding drive components 100, especially the setting of the licker-in roller 120, the continuity and uniformity of the cotton feeding process can be significantly improved, preventing uneven cotton feeding or cotton breakage caused by poor cotton layer sliding or fiber entanglement.

[0078] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0079] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application.
