Description

Technical Field

[0001] This application relates to the technical field of strip conveying, and more particularly to an adjustable taper roller and a strip conveying device. Background Technology

[0002] The battery manufacturing industry, papermaking industry, coating industry and other industries all need to use roller parts. Roller parts can be used not only for winding strips, but also for conveying strips.

[0003] During the conveying process of the strip, wrinkling often occurs due to the tension difference between the left and right sides of the strip or the difference in equipment debugging. That is, the tension of the two sides of the strip in the width direction is inconsistent. On the looser side, the strip will wrinkle, or on the tighter side, the strip will tear or deform. Summary of the Invention

[0004] In view of the above problems, this application provides an adjustable taper roller and a strip conveying device. The taper of the roller surface of the adjustable taper roller can be adjusted according to the tension of the two sides of the strip. When the strip passes through the roller surface, the end with the larger roller surface diameter corresponds to the looser side of the strip, and the end with the smaller roller surface diameter corresponds to the tighter side of the strip, thereby reducing the tension difference between the two sides of the strip and reducing the occurrence of strip wrinkling and tearing deformation.

[0005] According to one aspect of the embodiments of this application, a tapered adjustable roller is provided, which includes a support shaft, support plates, and a first pushing member; a plurality of support plates are arranged circumferentially around the support shaft, and the circumferential surfaces of the plurality of support plates away from the support shaft are combined to form a roller surface, and the support plates have a first end and a second end along the axial direction of the support shaft; the support plates can swing relative to the support shaft; the first pushing member is disposed on the support shaft and is used to push the first end of the plurality of support plates in a generally radial direction, so that the first end is close to the support shaft and the second end is away from the support shaft, or the first end is away from the support shaft and the second end is close to the support shaft, thereby causing the diameter of the roller surface to gradually change from the first end to the second end.

[0006] By adopting the above scheme, when the tapered adjustable roller is used to convey strip, the end with the larger roller diameter can be used to contact the looser side of the strip, and the end with the smaller roller diameter can be used to contact the tighter side of the strip. The contact area between the looser side of the strip and the roller surface is larger, and the contact area between the tighter side and the roller surface is smaller. This allows the looser side of the strip to be tensioned on the tapered adjustable roller, balancing the tension on both sides of the strip in the width direction, reducing the tension difference on both sides of the strip, and thus reducing the occurrence of strip wrinkling and tearing deformation.

[0007] In some embodiments, the tapered adjustable roller further includes an agglomerator that presses and / or tightens the support plates in a direction close to the support shaft, so that the plurality of support plates tend to converge toward the support shaft.

[0008] By adopting the above scheme, the agglomerating component makes multiple support plates tend to move closer to the support shaft, so as to prevent the multiple support plates from being pushed apart from the support shaft by the first pushing component and thus spreading out, thereby ensuring the structural integrity and stability of the tapered adjustable roller.

[0009] In some embodiments, the tapered adjustable roller further includes a second pusher for supporting the second ends of a plurality of support plates in a generally radial direction.

[0010] By adopting the above scheme, through the cooperation of the first and second pushers, the diameter of the tapered adjustable roller can be adjusted as needed to gradually decrease from the first end to the second end, or gradually increase from the first end to the second end. This allows the tapered adjustable roller to be used to adjust the tension on both sides of the strip under different tension conditions without changing the installation position and direction of the tapered adjustable roller. The tapered adjustable roller has stronger adaptability, a wider range of applications, and is more convenient to use.

[0011] In some embodiments, the support plate is provided with a swing support portion, which cooperates with the support shaft to support the support plate to swing around the swing support portion on the support shaft.

[0012] By adopting the above scheme, the support plate swings around the swing support part on the support shaft, making the swing range and swing amplitude of the support plate more controllable, which facilitates the application of the tapered adjustable roller in actual production.

[0013] In some embodiments, the tapered adjustable roller further includes a limiting portion disposed on the support shaft for limiting the swing support portion from swinging within the range defined by the limiting portion.

[0014] By adopting the above scheme, the swing support part and the limiting part cooperate to ensure that the support plate can only swing within the range limited by the limiting part, thereby further improving the controllability of the swing range and swing amplitude of the support plate.

[0015] In some embodiments, the limiting portion includes a groove provided on the support shaft, and a portion of the swing support portion swings within the groove.

[0016] By adopting the above scheme, the groove limits the position of the swing support on the support shaft, so that when the support plate is pushed by the first pusher or the second pusher, the swing support will swing in the groove and will not easily leave the groove and move along the axial direction of the support shaft. This makes the position of the roller surface formed by the support plate in the axial direction of the tapered adjustable roller remain largely unchanged, so as to facilitate the conveying of the strip on a fixed path.

[0017] In some embodiments, the portion of the swing support that contacts the groove is arc-shaped.

[0018] By adopting the above solution, the swing support can swing more smoothly and steadily within the groove.

[0019] In some embodiments, the first pusher includes a first pusher cone surface, the axial direction of which is parallel to the axis of the support shaft. The first pusher moves along the axial direction of the support shaft so that the first end of the support piece slides into contact with the first pusher cone surface and is pushed by the first pusher cone surface to move closer to or away from the support shaft.

[0020] By adopting the above scheme, when the first pusher moves along the axial direction of the support shaft while the support plate does not move along the axial direction of the support shaft, the movement of the first pusher along the axial direction of the support shaft can be converted into the swing of the support plate through the first pusher cone surface. That is, when the first pusher moves along the axial direction of the support shaft, the first pusher cone surface slides relative to the support plate, causing the first end of the support plate to gradually approach or move away from the support shaft.

[0021] In some embodiments, the support plate is provided with a first adjustment portion protruding toward the first push member, the first adjustment portion having a first contact surface, the first contact surface slidingly contacting the first push cone surface.

[0022] By adopting the above scheme, the support plate and the first pusher achieve relative movement through the sliding contact between the first contact surface and the first pusher cone surface, so that the support plate and the first pusher have larger force-bearing surfaces and less wear between them during the relative movement.

[0023] In some embodiments, the first pusher is threadedly connected to the support shaft along the axial direction of the support shaft.

[0024] By adopting the above scheme, when the first pusher rotates around the support shaft, the position of the first pusher in the axial direction of the support shaft can be adjusted, so that the first pusher pushes the first end of the support plate closer to or away from the support shaft. When the first pusher moves to any position, it can be self-locked by the threaded connection, so it will not move under the pressure of the support plate, thus ensuring the stability of the roller surface taper formed by the support plate.

[0025] In some embodiments, the second pusher includes a second pusher cone surface, the axial direction of which is parallel to the axis of the support shaft. The second pusher moves along the axial direction of the support shaft to make the second end of the support piece slide in contact with the pusher cone surface.

[0026] By adopting the above scheme, when the second pusher moves along the axial direction of the support shaft while the support plate does not move along the axial direction of the support shaft, the movement of the second pusher along the axial direction of the support shaft can be converted into the radial swing of the support plate along the support shaft through the second pusher cone surface. That is, when the second pusher moves along the axial direction of the support shaft, the second pusher cone surface slides relative to the support plate, causing the second end of the support plate to gradually approach or move away from the support shaft.

[0027] In some embodiments, the support plate is provided with a second adjustment portion protruding toward the second pusher, the second adjustment portion having a second contact surface, the second contact surface being in sliding contact with the second pusher cone surface.

[0028] By adopting the above scheme, the support plate and the second pusher achieve relative movement through the sliding contact between the second contact surface and the second pusher cone surface, so that the support plate and the second pusher have larger force-bearing surfaces and less wear between them during the relative movement.

[0029] In some embodiments, the support sheet includes a roller surface forming portion and a positioning portion, wherein at least a portion of the surface of the roller surface forming portion is used to form a roller surface; the positioning portion is located radially inside the roller surface forming portion; and the two ends of the support shaft are provided with stop portions, which cooperate with the positioning portion to restrict the axial movement of the support sheet.

[0030] By adopting the above scheme, the stop part can position the support piece in the axial direction of the support shaft, so that each support piece can only swing within the range limited by the stop part. Under the action of the first pusher or the second pusher, the support piece is not easy to move along the axial direction of the support shaft. The structure of the tapered adjustable roller is more stable, the roller surface formed by multiple support pieces is more regular, and the controllability of the roller surface taper is stronger.

[0031] In some embodiments, the support shaft includes an inner shaft and an outer shaft. The outer shaft has a through hole along its axial direction, the inner shaft is disposed in the through hole and rotatably supports the outer shaft, and the support plate is connected to the outer shaft.

[0032] By adopting the above scheme, the inner shaft can be used to fix the tapered adjustable roller to the external equipment. By rotating the inner shaft to support the outer shaft, the outer shaft can rotate around the inner shaft to transmit the strip under the friction of the strip when the inner shaft is fixedly connected to the external equipment, thereby reducing tearing of the strip and preventing damage to the strip.

[0033] In some embodiments, a first pusher is disposed between an outer shaft and an inner shaft, and at least a portion of a support plate penetrates the sidewall of the outer shaft and slides in contact with the first pusher.

[0034] By adopting the above scheme, the first pusher is set between the inner shaft and the outer shaft, so it will not occupy the space between the support shaft and the support plate, allowing the support plate to be adjusted to a greater range of taper outside the support shaft.

[0035] According to another aspect of the embodiments of this application, a strip conveying device is provided, including the tapered adjustable roller in any of the above-described embodiments.

[0036] By adopting the above solution, the tension on both sides of the strip during the conveying process can be adjusted by tapered adjustable rollers, reducing the problems of wrinkling, deformation and tearing of the strip.

[0037] In this embodiment, a first pushing member pushes multiple support plates, causing the diameter of the roller surface formed by the multiple support plates to gradually change from the first end to the second end, thus forming a conical surface. When the tapered adjustable roller is used to convey strip material, the end with the larger roller surface diameter can be used to contact the looser side of the strip material, and the end with the smaller roller surface diameter can be used to contact the tighter side of the strip material. The contact area between the looser side of the strip material and the roller surface is larger, and the contact area between the tighter side and the roller surface is smaller, thereby making the looser side of the strip material tensioned on the tapered adjustable roller, balancing the tightness on both sides of the strip material in the width direction, reducing the tension difference on both sides of the strip material, and thus reducing the occurrence of strip material wrinkling and tearing deformation.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0057] The terms "comprising" and "having," and any variations thereof, used in the specification, claims, and drawings of this application are intended to cover without excluding other meanings. The words "a" or "an" do not exclude the existence of multiple entities.

[0058] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of the phrase "embodiment" in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0059] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0060] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the tapered adjustable roller or strip conveying device of this application. For example, in the description of this application, the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0061] Furthermore, the terms "first," "second," etc., in the specification and claims of this application or in the aforementioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0062] In the description of this application, unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple groups" means two or more (including two groups).

[0063] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, "connection" or "linkage" in mechanical structures can refer to a physical connection, such as a fixed connection, for example, a connection fixed by fasteners, such as a connection fixed by screws, bolts, or other fasteners; a physical connection can also be a detachable connection, such as a snap-fit ​​or interlocking connection; a physical connection can also be an integral connection, such as a connection formed by welding, bonding, or integral molding. In circuit structures, "connection" or "linkage" can refer not only to a physical connection but also to an electrical connection or a signal connection. For example, it can be a direct connection, i.e., a physical connection, or an indirect connection through at least one intermediate component, as long as the circuit is connected; it can also refer to the internal connection of two components. Signal connection can refer not only to signal connection through a circuit but also to signal connection through a media, such as radio waves. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0064] Commonly used strip materials in production include paper, cloth, plastic film, battery electrodes, battery separators, etc. These strip materials need to be transferred from one process to another during the production process, or they need to be unwound, conveyed, and rewound in the same process, with corresponding operations performed during the conveying process.

[0065] Taking battery manufacturing as an example, battery electrodes undergo numerous processes during production, including coating, cold pressing, die cutting, slitting, and winding. Each process requires the electrodes to be transported. However, during production, it has been found that the electrodes often develop wrinkles, deformations, or tears.

[0066] The inventors discovered through research that this is because, during the transmission of the electrode sheet along its length, it is often unavoidable that there will be a difference in tension on both sides in the width direction. It is precisely because of this tension difference that the tension on both sides of the electrode sheet is inconsistent during the transmission process. On the looser side, the electrode sheet will wrinkle, while on the tighter side, the electrode sheet will deform or even tear due to the greater force.

[0067] In view of the above problems, this application provides a tapered adjustable roller. The taperedness of the roller surface can be adjusted according to the tension of the two sides of the strip. When the strip passes through the roller surface, the end with the larger roller surface diameter corresponds to the looser side of the strip, and the end with the smaller roller surface diameter corresponds to the tighter side of the strip, thereby reducing the tension difference between the two sides of the strip and reducing the occurrence of strip wrinkling and tearing deformation.

[0068] like Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, the tapered adjustable roller provided in this application embodiment includes a support shaft 1, support plates 2, and a first pushing member 4; multiple support plates 2 are arranged circumferentially around the support shaft 1, and the circumferential surfaces of the multiple support plates 2 away from the support shaft 1 are combined to form a roller surface 3. The support plates 2 have a first end 21 and a second end 22 along the axial direction of the support shaft 1; the support plates 2 can swing relative to the support shaft 1; the first pushing member 4 is provided on the support shaft 1 and is used to push the first end 21 of the multiple support plates 2 in the generally radial direction, so that the first end 21 is close to the support shaft 1 and the second end 22 is away from the support shaft 1, or the first end 21 is away from the support shaft 1 and the second end 22 is close to the support shaft 1, so that the diameter of the roller surface 3 gradually changes from the first end 21 to the second end 22.

[0069] The support shaft 1 is shaped like a shaft and can be a single piece or an assembly. The support shaft 1 provides support and positioning for multiple support plates 2, allowing the support plates 2 to be arranged around the support shaft 1 and to converge or disperse around it. The support shaft 1 can also be used to fix tapered adjustable rollers to external equipment, such as the frame of a strip conveyor.

[0070] There are multiple support plates 2, which are arranged circumferentially around the support shaft 1. Figure 4 To make the structure of the support plate 2 clearer, only a portion of the support plate 2 is shown in the diagram. It is understood that in actual use, there are more support plates 2 and they are arranged more densely. When the distance between the side of multiple support plates 2 away from the support shaft 1 and the support shaft 1 is approximately equal, the lines connecting the sides of multiple support plates 2 away from the support shaft 1 can form a closed polygon. When there are enough support plates 2, the polygon can be approximated as a circle. That is to say, the sides of multiple support plates 2 away from the support shaft 1 combine to form an approximate cylindrical structure to serve as the roller surface 3.

[0071] The function of the first pushing member 4 is to push the first ends 21 of the plurality of support plates 2 in a generally radial direction. The pushing direction can be either pushing in a direction closer to the support shaft 1 along the generally radial direction, so that the first end 21 is close to the support shaft 1 and the second end 22 is away from the support shaft 1, or pushing in a direction away from the support shaft 1 along the generally radial direction, so that the first end 21 is away from the support shaft 1 and the second end 22 is close to the support shaft 1. Here, the generally radial direction refers to the direction that differs from the radial direction of the support shaft 1 by less than 90°.

[0072] In order to ensure that a cylindrical or conical roller surface 3 is always formed between the multiple support plates 2, the first pusher 4 needs to be able to push the multiple support plates 2 simultaneously and make the multiple support plates 2 produce approximately the same displacement in their respective radial directions. Based on satisfying this condition, the shape and structure of the first pusher 4 can be arbitrarily selected, and the embodiments of this application do not limit this.

[0073] It should be noted that the first pushing member 4 is not limited to pushing the first end 21 of the support plate 2 by contacting the end of the first end 21 of the support plate 2. The first pushing member 4 can contact any position of the support plate 2 within half the length of the first end 21 along the length direction to achieve the purpose of pushing the first ends of multiple support plates 2.

[0074] When the distance between the multiple support plates 2 at different positions and the support shaft 1 changes, the diameter of the roller surface 3 also changes. When the distance between the multiple support plates 2 at different positions and the support shaft 1 is different, the diameter of the roller surface 3 at the corresponding positions is also different. This embodiment of the application utilizes this principle, and controls the distance between the support plates 2 and the support shaft 1 through the first pusher 4, thereby changing the diameter of the roller surface 3. When the first pusher 4 only pushes the first end 21 of the support plate 2, it can change the diameter of the first end 21, so that the diameter of the roller surface 3 changes in the direction from the first end 21 to the second end 22, that is, the roller surface 3 produces a taper. The taper of the roller surface 3 is adjusted by the first pusher 4 to adapt to the tension difference on both sides of the strip width direction. Figure 2 The tapered adjustable roller is in its initial state. At this time, the first pushing member 4 has not yet pushed the support plate 2 outward or inward, so the roller surface 3 of the tapered adjustable roller is cylindrical. Figure 3 The image shows the state after the first pusher 4 pushes the first end of the multiple support plates 2 outward. At this time, the diameter of the roller surface 3 of the tapered adjustable roller gradually decreases from the first end 21 to the second end 22, forming a tapered surface.

[0075] By adopting the above scheme, when the tapered adjustable roller is used to convey strip, the strip can wrap around a portion of the roller surface 3 of the tapered adjustable roller. The end of the roller surface 3 with a larger diameter is used to contact the looser side of the strip, and the end of the roller surface 3 with a smaller diameter is used to contact the tighter side of the strip. With the wrap angle between the strip width direction and the roller surface 3 remaining basically unchanged, the contact area between the looser side of the strip and the roller surface 3 is larger, and the contact area between the tighter side and the roller surface 3 is smaller. This allows the looser side of the strip to be tensioned on the tapered adjustable roller, balancing the tightness on both sides of the strip width direction, reducing the tension difference on both sides of the strip, and thus reducing the occurrence of strip wrinkling and tearing deformation.

[0076] like Figure 5As shown, in some embodiments, the tapered adjustable roller further includes an agglomerate 5 that presses and / or tightens the support plates 2 in a direction close to the support shaft 1, so that the plurality of support plates 2 tend to converge toward the support shaft 1.

[0077] The aggregate 5 can be disposed on the side of the multiple support plates 2 away from the support shaft 1, for example, as Figure 5 As shown, the polymer component 5 is an elastic sleeve that fits over the outside of multiple support plates 2 from the roller surface 3. The multiple support plates 2 converge towards the center under the compression of the elastic sleeve. The elastic sleeve can be made of rubber, plastic, silicone, resin, etc. The elastic sleeve can be fitted at specific locations on the support plates 2, such as the ends or the middle of the support plates 2. The elastic sleeve can also be relatively wide, thus fitting over the entire roller surface 3. It not only compresses the multiple support plates 2 towards the center but also covers the gaps between adjacent support plates 2, preventing the strip from being caught and broken.

[0078] The agglomerating component 5 can also be disposed on one side of the multiple support plates 2 near the support shaft 1. For example, the agglomerating component 5 can be a spring, with multiple springs provided, each spring connecting the support shaft 1 and a support plate 2 respectively. Under the tension of the spring, the support plate 2 tends to move towards the support shaft 1. Of course, the agglomerating component 5 can also be a tension band, elastic strip, etc., and this application embodiment does not limit it in this way.

[0079] Without external force, the agglomerating member 5 causes multiple support plates 2 to converge toward the support shaft 1, thereby forming a compact cylinder or similar cylindrical, conical, or similar conical structure around the support shaft 1. When the first pushing member 4 pushes the multiple support plates 2 away from the support shaft 1, the agglomerating member 5 provides a force for the multiple support plates 2 to move toward the support shaft 1 to counteract the pushing force of the first pushing member 4. This ensures that the multiple support plates 2 maintain structural integrity even when away from the support shaft 1, preventing them from detaching and spreading out, thus ensuring the structural integrity and stability of the tapered adjustable roller. When the first pushing member 4 cancels or reduces the pushing force on each support plate 2, the multiple support plates 2 converge toward the support shaft 1 under the action of the agglomerating member 5 to reduce the taper of the roller surface 3, thereby achieving the purpose of flexibly adjusting the taper of the tapered adjustable roller.

[0080] like Figure 6 As shown, in some embodiments, the tapered adjustable roller further includes a second pusher 6 for supporting the second ends 22 of the plurality of support plates 2 in a generally radial direction.

[0081] The structure of the second pusher 6 is the same as or similar to that of the first pusher 4. The relevant descriptions of the first pusher 4 in this application can be applied to the second pusher 6. The structure and effects of the second pusher 6 will not be repeated in this application.

[0082] It should be noted that the second pushing member 6 is not limited to pushing the second end 22 of the support plate 2 by contacting the end of the second end 22 of the support plate 2. The second pushing member 6 can contact any position of the support plate 2 within half the length of the second end 22 along the length direction.

[0083] The above solution, through the cooperation of the first pusher 4 and the second pusher 6, allows the diameter of the tapered adjustable roller surface 3 to be adjusted as needed to gradually decrease from the first end 21 to the second end 22, or gradually increase from the first end 21 to the second end 22. This allows the tapered adjustable roller to be used to adjust the tension on both sides of the strip under different tension conditions without changing the installation position and direction of the tapered adjustable roller. In addition, through the mutual cooperation of the first pusher 4 and the second pusher 6, not only can the tapered adjustable roller surface 3 form conical surfaces with different tapers, but it can also form cylindrical surfaces with different diameters. The tapered adjustable roller has stronger adaptability, a wider range of applications, and is more convenient to use.

[0084] like Figure 6 and Figure 7 As shown, in some embodiments, the support plate 2 is provided with a swing support portion 23, which cooperates with the support shaft 1 to support the support plate 2 to swing around the swing support portion 23 on the support shaft 1.

[0085] The swing support 23 can be a protrusion provided on the support plate. The protrusion can abut against the support shaft 1 or be connected to the support shaft 1 by a hinge, so that the support plate 2 can swing around the swing support 23 on the support shaft 1.

[0086] By adopting the above scheme, the support plate 2 swings around the swing support part 23 on the support shaft 1, making the swing range and swing amplitude of the support plate 2 more controllable, which facilitates the application of the tapered adjustable roller in actual production.

[0087] like Figure 6 and Figure 7 As shown, in some embodiments, the tapered adjustable roller further includes a limiting part 11, which is disposed on the support shaft 1 and is used to limit the swing support part 23 from swinging within the range defined by the limiting part 11.

[0088] The limiting part 11 can be a recessed structure provided on the support shaft 1, or it can be a hole or groove provided on the support shaft 1 for hinged connection with the swing support part 23. The limiting part 11 can be integrally formed with the support shaft 1, or it can be an additional part connected to the support shaft 1. Of course, the limiting part 11 can also be a flexible member such as a rope. One end of the flexible member is connected to the support shaft 1, and the other end is connected to the swing support part 23, thereby limiting the swing of the swing support part 23 within the range defined by the flexible member, and further improving the controllability of the swing range and swing amplitude of the support piece 2.

[0089] like Figure 6 As shown, the limiting part 11 can be provided at the middle of the support shaft 1 along the axial direction; as Figure 7 As shown, the limiting part 11 can also be located near the end of either end of the support shaft 1.

[0090] It is important to note that, such as Figure 6 As shown, the mating structure between the swing support 23 and the limiting part 11 can be set at the middle of the tapered adjustable roller along its length, such as... Figure 7 As shown, the cooperation structure between the swing support 23 and the limiting part 11 can also be set at any end of the tapered adjustable roller along the length direction, and this application embodiment does not impose any restrictions.

[0091] like Figure 6 and Figure 7 As shown, in some embodiments, the limiting part 11 includes a groove 111 provided on the support shaft 1, and a portion of the swing support part 23 swings within the groove 111.

[0092] The groove 111 is a recessed structure from the surface of the support shaft 1. The groove 111 can be formed by removing material from the support shaft 1. This type of limiting part 11 does not need to occupy the space outside the surface of the support shaft 1.

[0093] When a portion of the swing support 23 swings within the groove 111, the inner wall of the groove 111 abuts against the portion of the swing support 23 located within the groove 111. The groove 111 provides resistance to the swing support 23, so that when the support piece 2 is pushed by the first pusher 4 or the second pusher 6, the swing support 23 will swing within the groove 111 and will not easily detach from the groove 111 and move along the axial direction of the support shaft 1. This ensures that the position of the roller surface 3 formed by the support piece 2 in the axial direction of the tapered adjustable roller remains approximately unchanged, so as to facilitate the conveying of the strip on a fixed path.

[0094] like Figure 6 and Figure 7 As shown, in some embodiments, the portions of the swing support 23 and the groove 111 that come into contact are both arc-shaped.

[0095] When the swing support 23 swings with the support plate 2 and rotates in the groove 111, the surface of the swing support 23 in contact with the groove 111 becomes smoother, the rotational resistance is smaller, and the swing of the swing support 23 in the groove 111 becomes more stable and smooth.

[0096] like Figure 8 and Figure 9 As shown, in some embodiments, the first pushing member 4 includes a first pushing cone surface 41, the axial direction of the first pushing cone surface 41 is parallel to the axis of the support shaft 1, and the first pushing member 4 moves along the axial direction of the support shaft 1 so that the first end 21 of the support piece 2 slides into contact with the first pushing cone surface 41 and is pushed by the first pushing cone surface 41 to move closer to or away from the support shaft 1.

[0097] By adopting the above scheme, when the first pusher 4 moves along the axial direction of the support shaft 1 while the support plate 2 does not move along the axial direction of the support shaft 1, by setting the first pusher cone surface 41, the movement of the first pusher 4 along the axial direction of the support shaft 1 can be converted into the swing of the support plate 2. That is, when the first pusher 4 moves along the axial direction of the support shaft 1, the first pusher cone surface 41 slides relative to the support plate 2, so that the first end 21 of the support plate 2 gradually approaches or moves away from the support shaft 1.

[0098] Since the axial direction of the first pushing cone surface 41 is parallel to the axial direction of the support shaft 1, when the axial direction of the first pushing cone surface 41 coincides with the axial direction of the support shaft 1, the distance between the generatrix of the first pushing cone surface 41 and the axis of the support shaft 1 is equal. When the first pushing member 4 moves along the axial direction of the support shaft 1, the first pushing cone surface 41 can drive each support piece 2 to make oscillating movements with equal or similar amplitudes at the same time, so that multiple support pieces 2 can form a relatively neat cone surface at any angle.

[0099] like Figure 9 As shown, in some embodiments, the support plate 2 is provided with a first adjustment part 24 protruding toward the first push member 4. The first adjustment part 24 has a first contact surface 241, which slides in contact with the first push cone surface 41.

[0100] The first adjustment part 24 protrudes toward the support shaft 1, and the first contact surface 241 is located on the end face of the first adjustment part 24 near the support shaft 1. The first contact surface 241 can be a part of the end face or the entire end face.

[0101] The first contact surface 241 can be an inclined surface or an arc surface. When the first contact surface 241 is an inclined surface, the inclination direction of the first contact surface 241 is approximately the same as the inclination direction of the first pushing cone surface 41. "Approximately the same" means that the first pushing cone surface 41 gradually approaches the support shaft 1 from the first end 21 to the second end 22, and the inclined surface on the support plate 2 also gradually approaches the support shaft 1 from the first end 21 to the second end 22. The specific degree of inclination of the first pushing cone surface 41 and the inclined surface is not limited. When the first contact surface 241 is an arc surface, the axis of the arc surface is located on the side of the arc surface away from the support shaft 1.

[0102] Although the relative angle between the first contact surface 241 and the first push cone surface 41 changes during the movement of the first push member 4 along the axis of the support shaft 1, the cooperation between the first contact surface 241 and the first push cone surface 41 can still increase the contact area between the support plate 2 and the first push member 4 and buffer the impact when the support plate 2 and the first push member 4 move relative to each other, thereby reducing the wear between the support plate 2 and the first push member 4.

[0103] like Figure 9 As shown, in some embodiments, the first pusher 4 is threadedly connected to the support shaft 1 along the axial direction of the support shaft 1.

[0104] By adopting the above scheme, when the first pusher 4 rotates relative to the support shaft 1, the position of the first pusher 4 in the axial direction of the support shaft 1 can be adjusted, so that the first pusher 4 pushes the first end 21 of the support plate 2 closer to or away from the support shaft 1. When the first pusher 4 moves to any position, it can be self-locked by the threaded connection, so it will not move under the pressure of the support plate 2, thus ensuring the stability of the tapered roller surface 3 formed by the support plate 2.

[0105] Furthermore, when the first contact surface 241 coincides with the axis of the support shaft 1, and when the axis of the threaded connection coincides with the axis of the support shaft 1, during the rotation of the first pusher 4 relative to the support shaft 1, the distance of the first contact surface 241 relative to the axis of the support shaft 1 in each direction is equal or substantially equal. Therefore, the tilt angles of the multiple support pieces 2 controlled by the first contact surface 241 from the first end 21 to the second end 22 are equal or substantially equal. That is, during the movement, the first pusher 4 pushes each support piece 2 to tilt at an equal angle from the first end 21 to the second end 22, so that the multiple support pieces 2 form a relatively regular conical roller surface 3.

[0106] like Figure 10 and Figure 11As shown, in some embodiments, the second pusher 6 includes a second pusher cone surface 61, the axial direction of which is parallel to the axis of the support shaft 1. The second pusher 6 moves along the axial direction of the support shaft 1 so that the second end 22 of the support piece 2 slides in contact with the pusher cone surface.

[0107] The possible structure and function of the second jacking cone surface 61 are the same as or similar to those of the first jacking cone surface 41, and will not be described again in this embodiment of the application.

[0108] By adopting the above scheme, when the second pusher 6 moves along the axial direction of the support shaft 1 while the support plate 2 does not move along the axial direction of the support shaft 1, the movement of the second pusher 6 along the axial direction of the support shaft can be converted into the swing of the support plate 2 through the second pusher cone surface 61. That is, when the second pusher 6 moves along the axial direction of the support shaft 1, the second pusher cone surface 61 slides relative to the support plate 2, so that the second end 22 of the support plate 2 gradually approaches or moves away from the support shaft 1.

[0109] like Figure 11 As shown, in some embodiments, the support plate 2 is provided with a second adjustment part 27 protruding toward the second push member 6. The second adjustment part 27 has a second contact surface 271, which slides in contact with the second push cone surface 61.

[0110] The possible structure and function of the second adjustment part 27 are the same as or similar to those of the first adjustment part 24, and the possible structure and function of the second contact surface 271 are the same as or similar to those of the first contact surface 241. For details, please refer to the description of the relevant embodiments of the first adjustment part 24 and the first contact surface 241. This embodiment will not be described again in this application.

[0111] By adopting the above scheme, the support plate 2 and the second pusher 6 achieve relative movement through the sliding contact between the second contact surface 271 and the second pusher cone surface 61, so that the support plate 2 and the second pusher 6 have larger force-bearing surfaces and less wear between them during the relative movement.

[0112] like Figure 12 and Figure 13 As shown, in some embodiments, the support piece 2 includes a roller forming part 25 and a positioning part 26. At least a portion of the surface of the roller forming part 25 is used to form the roller surface 3. The positioning part 26 is located radially inside the roller forming part 25. The two ends of the support shaft 1 are provided with stop parts 16, which cooperate with the positioning part 26 to restrict the axial movement of the support piece 2.

[0113] The roller surface forming part 25 extends along the length direction of the tapered adjustable roller. The part of the roller surface forming part 25 used to form the roller surface 3 can be a plane or a curved surface. When multiple roller surface forming parts 25 are evenly arranged, the multiple roller surface forming parts 25 form an approximately cylindrical or conical shape.

[0114] The length and width of the positioning part 26 can be smaller than the roller forming part 25. The number of positioning parts 26 can be one or more. The positioning part 26 can be installed on the outside of the support shaft 1, or a groove can be made on the support shaft and the positioning part 26 can be installed in the groove.

[0115] For example, such as Figure 14 As shown, in one embodiment, a positioning groove 12 is provided on the outer wall of the support shaft 1. The length direction of the positioning part 26 is parallel to the length direction of the support shaft 1, and the width direction of the positioning part 26 is perpendicular to the length direction of the support shaft 1. The width of the positioning part 26 is smaller than the width of the positioning groove 12, and the length of the positioning part 26 is smaller than the length of the positioning groove 12, so that the positioning part 26 can be inserted into the positioning groove 12. One positioning part 26 is provided. The bottom surface of the positioning groove 12 is arc-shaped along its length. The positioning part 26 has an arc-shaped surface that mates with the bottom surface of the positioning groove 12. When the support piece 2 is pushed by the first pushing member 4 or the second pushing member 6, the positioning part 26 rotates within the positioning groove 12. During rotation, the positioning part 26 and the positioning groove 12 maintain arc-shaped surface contact at all times. The positioning groove 12 provides better support for the support piece 2 and facilitates the smooth rotation of the support piece 2.

[0116] By cooperating with the positioning part 26 and the positioning groove 12, each support piece 2 can only move or rotate within the range defined by the positioning groove 12. The positioning groove 12 can not only position the support piece 2 in the circumferential direction of the support shaft 1, but also position the support piece 2 in the axial direction of the support shaft 1. The roller surface 3 formed by multiple support pieces 2 is more regular, and the structure of the tapered adjustable roller is more stable.

[0117] Stops 16 are provided at both ends of the support shaft 1. The distance between two stops 16 can be greater than the maximum length of the positioning part 26, or the maximum distance between two positioning parts 26 located at the two ends of the support piece 2 along the length direction among multiple positioning parts 26. This allows the support piece 2 to have a certain amount of room for movement along the axial direction of the support shaft 1 during the swinging process, so that the support piece 2 can swing freely to form roller surfaces 3 with different tapers.

[0118] When the range of motion of the support piece 2 exceeds the space defined by the two stops 16, the two stops 16 can position the support piece 2 in the axial direction of the support shaft 1, so that each support piece 2 can only swing within the range defined by the stops 16. Under the action of the first pusher 4 or the second pusher 6, the support piece 2 is not easy to move along the axial direction of the support shaft 1, the structure of the tapered adjustable roller is more stable, the roller surface 3 formed by multiple support pieces 2 is more regular, and the taper of the roller surface 3 is more controllable.

[0119] like Figure 12As shown, in some embodiments, the width of the positioning part 26 in the direction perpendicular to the axis of the support shaft 1 is smaller than the width of the roller forming part 25.

[0120] The roller forming part 25 is used to form the roller surface 3, and the positioning part 26 is used to cooperate with the positioning groove 12 on the support shaft 1. Therefore, the positioning part 26 is closer to the support shaft 1 than the roller forming part 25. That is, when the axis of the support shaft 1 is taken as the axis, the circumferential diameter of the roller forming part 25 is larger, and the circumferential diameter of the positioning part 26 is smaller. Therefore, when the width of the positioning part 26 in the direction perpendicular to the axis of the support shaft 1 is smaller than the width of the roller forming part 25, during the process of the diameter of the roller surface 3 formed by the support piece 2 decreasing, the adjacent positioning part 26 cannot contact the adjacent roller forming part 25 first. This allows the roller forming parts 25 of the adjacent support pieces 2 to move freely closer or further away. The diameter of the roller surface 3 of the tapered adjustable roller depends on the distance between the adjacent roller forming parts 25. The diameter and taper adjustment of the roller forming part 25 are more flexible and have a wider adjustment range.

[0121] like Figure 13 and Figure 14 As shown, in some embodiments, the support shaft 1 includes an inner shaft 13 and an outer shaft 14. The outer shaft 14 has a through hole 141 along its axial direction. The inner shaft 13 is disposed in the through hole 141 and rotatably supports the outer shaft 14. The support piece 2 is connected to the outer shaft 14.

[0122] The inner shaft 13 can be a stepped shaft, and the through hole 141 of the outer shaft 14 can be a stepped hole. The inner shaft 13 and the outer shaft 14 can rotate in the circumferential direction. That is, only the outer circumference can rotate while the inner shaft 13 remains stationary; or only the inner shaft 13 can rotate while the outer shaft 14 remains stationary. This kind of fit can be achieved by a clearance fit between the inner shaft 13 and the outer shaft 14, or by installing a bearing 15 between the inner shaft 13 and the outer shaft 14. In this installation state, the inner shaft 13 can be fixedly installed on external equipment, while the outer shaft 14 rotates relative to the inner shaft 13 under the friction of the strip to transmit the strip and tension the strip, reduce tearing of the strip, and prevent damage to the strip.

[0123] like Figure 12 As shown, in some embodiments, the first pusher 4 is disposed between the outer shaft 14 and the inner shaft 13, and at least a portion of the support piece 2 penetrates the side wall of the outer shaft 14 and slides in contact with the first pusher 4.

[0124] By adopting the above scheme, the first pusher 4 is set between the inner shaft 13 and the outer shaft 14, so it will not occupy the space between the support shaft 1 and the support plate 2, allowing the support plate 2 to be adjusted to a greater range of taper outside the support shaft 1.

[0125] According to another aspect of the embodiments of this application, a strip conveying device is provided, including the tapered adjustable roller in any of the above-described embodiments.

[0126] By adopting the above solution, the tension on both sides of the strip during the conveying process can be adjusted by tapered adjustable rollers, reducing the problems of wrinkling, deformation and tearing of the strip.

[0127] In summary, the embodiments of this application push multiple support plates 2 by the first pusher 4, so that the diameter of the roller surface 3 formed by the multiple support plates 2 gradually changes from the first end 21 to the second end 22 to form a conical surface. When the tapered adjustable roller is used to convey the strip, the end with the larger diameter of the roller surface 3 can be used to contact the looser side of the strip, and the end with the smaller diameter of the roller surface 3 can be used to contact the tighter side of the strip. The contact area between the looser side of the strip and the roller surface 3 is larger, and the contact area between the tighter side and the roller surface 3 is smaller, so that the looser side of the strip is tensioned on the tapered adjustable roller, balancing the tightness on both sides of the strip width direction, reducing the tension difference on both sides of the strip, and thus reducing the occurrence of strip wrinkling and tearing deformation.
