技术领域
本申请实施例涉及带材传送的技术领域，尤其涉及一种锥度可调辊和带材传送装置。
背景技术
电池制造行业、造纸行业、涂布行业等均需要用到辊类的零件，辊类零件不仅能够用于卷绕带材，还能够用于传送带材。
在带材的传送过程中，由于带材左右两边张力差异，或设备调试上的差异导致带材在传送过程中常常出现打皱现象，即带材宽度方向的两侧松紧不一致，在较松的一侧，带材会出现褶皱，或者在较紧的一侧，带材出现撕裂或变形。
发明内容
鉴于上述问题，本申请实施例提供了一种锥度可调辊和带材传送装置，锥度可调辊的辊面的锥度可根据带材两侧的松紧度调节，带材在经过辊面时，辊面直径较大的一端对应于带材较松的一侧，辊面直径较小的一端对应带材较紧的一侧，从而减小带材两侧的张力差，减少带材打皱和撕裂变形的情况的发生。
根据本申请实施例的一个方面，提供了一种锥度可调辊，其包括支撑轴、支撑片和第一顶推件；支撑片围绕支撑轴的周向设置有多个，多个支撑片远离支撑轴的一侧的周面组合形成辊面，支撑片沿支撑轴的轴向具有第一端和第二端；支撑片可相对支撑轴做摆动运动；第一顶推件设于支撑轴上，用于在大体径向方向上顶推多个支撑片的第一端，以使第一端靠近支撑轴，并使第二端远离支撑轴，或者使第一端远离支撑轴，并使第二端靠近支撑轴，从而使辊面从第一端到第二端的直径逐渐变化。
通过采用上述方案，当该锥度可调辊用于传送带材时，可将辊面直径较大的一端用于接触带材较松的一侧，辊面直径较小的一端用于接触带材较紧的一侧，带材较松的一侧与辊面之间接触的面积较大，较紧的一侧与辊面的接触面积较小，从而使带材较松的一侧在锥度可调辊上被张紧，平衡带材宽度方向两侧的松紧度，减小带材两侧的张力差，从而减少带材打皱和撕裂变形的问题的发生。
在一些实施例中，锥度可调辊还包括聚合件，聚合件向靠近支撑轴的方向上挤压和/或拉紧支撑片，以使多个支撑片具有向支撑轴靠拢的趋势。
通过采用上述方案，聚合件使多个支撑片具有向支撑轴靠拢的趋势，以防止多个支撑片之间受到第一顶推件的顶推而与支撑轴之间脱离，从而散开，确保了锥度可调辊的结构完整性和稳定性。
在一些实施例中，锥度可调辊还包括第二顶推件，第二顶推件用于在大体径向方向上支撑多个支撑片的第二端。
通过采用上述方案，通过第一顶推件和第二顶推件的配合，使得锥度可调辊的辊面直径可以根据需要调节至从第一端到第二端逐渐减小，或者从第一端到第二端逐渐增大，以在不调换锥度可调辊的安装位置和方向的前提下，使得锥度可调辊能够用于对不同张力情况的带材进行两侧的松紧度调节，锥度可调辊的适应性更强，应用范围更广，使用也更加方便。
在一些实施例中，支撑片上设有摆动支撑部，摆动支撑部与支撑轴配合，以支撑支撑片围绕摆动支撑部在支撑轴上摆动。
通过采用上述方案，支撑片在支撑轴上围绕摆动支撑部为支点摆动，使得支撑片的摆动范围和摆动幅度更加具有可控性，便于锥度可调辊在实际生产中应用。
在一些实施例中，锥度可调辊还包括限位部，限位部设于支撑轴上，用于限制摆动支撑部在限位部限定的范围内摆动。
通过采用上述方案，摆动支撑部与限位部配合，使得支撑片带动摆动支撑部只能在限位部限定的范围内摆动，进一步提高支撑片的摆动范围和摆动幅度的可控性。
在一些实施例中，限位部包括设于支撑轴上的凹槽，摆动支撑部的一部分在凹槽内摆动。
通过采用上述方案，凹槽限定摆动支撑部在支撑轴上的位置，使得支撑片 受到第一顶推件或者第二顶推件的顶推时，摆动支撑部会在凹槽内摆动，而不容易脱离凹槽而沿支撑轴的轴线方向移动，从而使得支撑片形成的辊面在锥度可调辊轴向上的位置大体不变，以便于在固定路径上传送带材。
在一些实施例中，摆动支撑部和凹槽相接触的部分均为弧形。
通过采用上述方案，摆动支撑部在凹槽内的摆动更加平稳顺畅。
在一些实施例中，第一顶推件包括第一顶推锥面，第一顶推锥面的轴线方向与支撑轴的轴线平行，第一顶推件沿支撑轴的轴线方向移动，以使支撑片的第一端与第一顶推锥面滑动接触并被第一顶推锥面顶推而靠近或远离支撑轴。
通过采用上述方案，当第一顶推件沿支撑轴的轴线方向移动而支撑片在支撑轴的轴线方向不移动时，通过第一顶推锥面，可以将第一顶推件沿支撑轴的轴线方向的运动转化成支撑片的摆动，即第一顶推件沿支撑轴的轴线运动时，第一顶推锥面相对支撑片滑移而使得支撑片的第一端逐渐靠近或远离支撑轴。
在一些实施例中，支撑片上设有朝第一顶推件凸出的第一调节部，第一调节部具有第一接触面，第一接触面与第一顶推锥面滑动接触。
通过采用上述方案，支撑片与第一顶推件之间通过第一接触面与第一顶推锥面的滑动接触来实现相对运动，使得支撑片与第一顶推件在相对运动的过程中，各自的受力面更大，相互之间的磨损更小。
在一些实施例中，第一顶推件沿支撑轴的轴线方向与支撑轴螺纹连接。
通过采用上述方案，当第一顶推件绕支撑轴转动时，能够调整第一顶推件在支撑轴的轴线方向的位置，从而使第一顶推件顶推支撑片的第一端靠近或远离支撑轴，而当第一顶推件移动到任意位置时，能够通过螺纹连接进行自锁，因此不会在支撑片的挤压下发生移动，确保支撑片形成的辊面锥度的稳定性。
在一些实施例中，第二顶推件包括第二顶推锥面，第二顶推锥面的轴线方向与支撑轴的轴线平行，第二顶推件沿支撑轴的轴线方向移动，以使支撑片的第二端与顶推锥面滑动接触。
通过采用上述方案，当第二顶推件沿支撑轴的轴线方向移动而支撑片在支撑轴的轴线方向不移动时，通过第二顶推锥面，可以将第二顶推件沿支撑轴的轴线方向的运动转化成支撑片沿支撑轴径向的摆动，即第二顶推件沿支撑轴的轴线运动时，第二顶推锥面相对支撑片滑移而使得支撑片的第二端逐渐靠近或远离支撑轴。
在一些实施例中，支撑片上设有朝第二顶推件凸出的第二调节部，第二调 节部具有第二接触面，第二接触面与第二顶推锥面滑动接触。
通过采用上述方案，支撑片与第二顶推件之间通过第二接触面与第二顶推锥面的滑动接触来实现相对运动，使得支撑片与第二顶推件在相对运动的过程中，各自的受力面更大，相互之间的磨损更小。
在一些实施例中，支撑片包括辊面成型部和定位部，辊面成型部至少部分表面用于构成辊面；定位部位于辊面成型部的径向内侧；支撑轴的两端设有止挡部，止挡部与定位部配合，以限制支撑片的轴向运动。
通过采用上述方案，止挡部能够在支撑轴的轴向上定位支撑片，使得每个支撑片只能在止挡部限定的范围内摆动，在第一顶推件或第二顶推件的作用下，支撑片不容易沿支撑轴的轴向移动，锥度可调辊的结构更加稳定，多个支撑片形成的辊面更加规整，辊面锥度的可控性更强。
在一些实施例中，支撑轴包括内轴和外轴，外轴沿其轴向设有通孔，内轴设于通孔内并转动支撑外轴，支撑片连接于外轴上。
通过采用上述方案，内轴可以用于锥度可调辊与外界设备的固定，通过使内轴转动支撑外轴，使得在内轴与外界设备固定连接的情况下，外轴在带材的摩擦下能够围绕内轴转动以传送带材，并减小对带材的撕扯，防止对带材造成损坏。
在一些实施例中，第一顶推件设于外轴与内轴之间，支撑片的至少部分贯穿外轴的侧壁而与第一顶推件滑动接触。
通过采用上述方案，第一顶推件设置在内轴与外轴之间，所以不会占用支撑轴与支撑片之间的空间，使得支撑片在支撑轴外部可以进行更大范围的锥度调节。
根据本申请实施例的另一方面，提供了一种带材传送装置，包括上述主题任一实施例中的锥度可调辊。
通过采用上述方案，带材在传送过程中的两侧松紧度可以通过锥度可调辊进行调节，减少带材出现打皱、变形和撕裂的问题。
本申请实施例通过第一顶推件顶推多个支撑片，使得多个支撑片形成的辊面直径从第一端到第二端的逐渐变化而形成锥面，当该锥度可调辊用于传送带材时，可将辊面直径较大的一端用于接触带材较松的一侧，辊面直径较小的一端用于接触带材较紧的一侧，带材较松的一侧与辊面之间接触的面积较大，较紧的一侧与辊面的接触面积较小，从而使带材较松的一侧在锥度可调辊上被张 紧，平衡带材宽度方向两侧的松紧度，减小带材两侧的张力差，从而减少带材打皱和撕裂变形的问题的发生。

生产中常见的带材包括纸张、布匹、塑料膜、电池的极片、电池的隔离膜等等，这些带材在生产过程中需要从一个工序传到另一个工序，或者需要在同一个工序中进行放卷、传送、收卷，在传送过程中进行相应的操作。
以电池制造为例，电池的极片在生产过程中需要经过涂布、冷压、模切、分条、卷绕等诸多工序，每个工序均需要极片在传送过程中进行。但是在生产过程中发现，极片常常会出现褶皱、变形或撕裂。
本申请的发明人经过研究发现，这是由于极片在沿长度方向传送的过程中常常不可避免的会出现宽度方向的两侧张力不同。而正是由于极片两侧存在张力差异，导致带材在传送过程中的两侧松紧不一致，在较松的一侧，极片会出现褶皱，在较紧的一侧，极片由于受力较大而出现变形甚至撕裂。
鉴于上述问题，本申请实施例提供了一种锥度可调辊，锥度可调辊的辊面的锥度可根据带材两侧的松紧度调节，带材在经过辊面时，辊面直径较大的一端对应于带材较松的一侧，辊面直径较小的一端对应带材较紧的一侧，从而减小带材两侧的张力差，减少带材打皱和撕裂变形的情况的发生。
如图1、图2、图3和图4所示，本申请实施例提供的锥度可调辊包括支撑 轴1、支撑片2和第一顶推件4；支撑片2围绕支撑轴1的周向设置有多个，多个支撑片2远离支撑轴1的一侧的周面组合形成辊面3，支撑片2沿支撑轴1的轴向具有第一端21和第二端22；支撑片2可相对支撑轴1做摆动运动；第一顶推件4设于支撑轴1上，用于在大体径向方向上顶推多个支撑片2的第一端21，以使第一端21靠近支撑轴1，并使第二端22远离支撑轴1，或者使第一端21远离支撑轴1，并使第二端22靠近支撑轴1，从而使辊面3从第一端21到第二端22的直径逐渐变化。
支撑轴1整体呈轴杆状，其可以是一个整体件，也可以是组合件，支撑轴1为多个支撑片2提供支撑和定位，使得多个支撑片2能够以支撑轴1为中心排布，并以支撑轴1为中心聚拢或分散。支撑轴1还能用于将锥度可调辊固定在外部设备上，比如带材传送设备的机架上。
支撑片2有多个，并围绕支撑轴1的周向设置，图4中为了便于看清支撑片2和的结构而仅仅示意出部分支撑片2，可以理解的是，在实际使用过程中支撑片2的数量更多，排布更加密集，在多个支撑片2远离支撑轴1的一侧与支撑轴1之间的距离大致相等的情况下，多个支撑片2远离支撑轴1的一侧的连线便能够组成一个封闭的多边形，当支撑片2的数量足够多的时候，该多边形便能够近似为圆，也就是说，多个支撑片2远离支撑轴1的一侧组合形成近似圆柱面的结构以作为辊面3。
第一顶推件4的作用是在大体径向方向上顶推多个支撑片2的第一端21，顶推方向可以是沿大体径向方向向靠近支撑轴1的方向上顶推，以使得第一端21靠近支撑轴1，并使第二端22远离支撑轴1，也可以是沿大体径向方向向远离支撑轴1的方向上顶推，以使得第一端21远离支撑轴1，并使第二端22靠近支撑轴1。其中，大体径向方向是指与支撑轴1的径向方向相差90°以内的方向。
要想使多个支撑片2之间始终形成圆柱形或者圆锥形的辊面3，第一顶推件4需要能够同时顶推多个支撑片2，且使多个支撑片2在各自所在的径向上产生大致相同的位移，在满足该条件的基础上，第一顶推件4的形状结构可以是任意选择，本申请实施例对此不做限定。
需要注意的是，第一顶推件4并不限于通过与支撑片2的第一端21的端部接触来顶推支撑片2的第一端21，第一顶推件4可以与支撑片2沿长度方向靠近第一端21的一半长度范围内的任意位置接触来达到顶推多个支撑片2的第一 端的目的。
当多个支撑片2的不同位置与支撑轴1之间的距离发生改变时，辊面3的直径也会发生变化，多个支撑片2的不同位置与支撑轴1之间的距离不同时，不同位置对应处的辊面3的直径也不同，本申请此实施例利用此原理，通过第一顶推件4控制支撑片2与支撑轴1之间的距离，从而改变辊面3的直径，当第一顶推件4仅仅顶推支撑片2的第一端21时，便能够改变第一端21的直径，使得辊面3在从第一端21到第二端22的方向上的辊面3直径产生变化，即辊面3产生锥度，通过第一顶推件4调节辊面3的锥度大小，使之适应带材宽度方向的两侧的张力差。图2中的锥度可调辊为初始状态，此时第一顶推件4还未向外或向内顶推支撑片2，因此锥度可调辊的辊面3呈现柱状，图3示出了第一顶推件4向外顶推多个支撑片2的第一端之后的状态，此时锥度可调辊的辊面3从第一端21到第二端22的直径逐渐减小而呈锥面。
通过采用上述方案，当该锥度可调辊用于传送带材时，可使带材包裹锥度可调辊的辊面3的部分，其中辊面3的直径较大的一端用于接触带材较松的一侧，辊面3的直径较小的一端用于接触带材较紧的一侧，在带材宽度方向与辊面3的包角大小基本不变的情况下，带材较松的一侧与辊面3之间接触的面积较大，较紧的一侧与辊面3的接触面积较小，从而使带材较松的一侧在锥度可调辊上被张紧，平衡带材宽度方向两侧的松紧度，减小带材两侧的张力差，从而减少带材打皱和撕裂变形的问题的发生。
如图5所示，在一些实施例中，锥度可调辊还包括聚合件5，聚合件5向靠近支撑轴1的方向上挤压和/或拉紧支撑片2，以使多个支撑片2具有向支撑轴1靠拢的趋势。
聚合件5可以设置在多个支撑片2远离支撑轴1的一侧，例如，如图5所示，聚合件5为弹性胶套，弹性胶套从辊面3上套在多个支撑片2的外侧，多个支撑片2在弹性胶套的挤压作用下向中间聚拢。弹性胶套的材质可以是橡胶、塑胶、硅胶、树脂材料等等。弹性胶套可以套在支撑片2的局部位置，例如，支撑片2的端部、支撑片2的中间等等，弹性胶套还可以比较宽，从而套在整个辊面3上，不仅能够用于向中间挤压多个支撑片2，还能够覆盖相邻支撑片2之间的缝隙，防止带材夹在相邻支撑片2之间的缝隙中而被夹断。
聚合件5还可以设置在多个支撑片2靠近支撑轴1的一侧，例如，聚合件5为弹簧，弹簧设置有多个，每个弹簧分别连接支撑轴1和一个支撑片2，支撑片 2在弹簧的拉力作用下具有向支撑轴1靠拢的趋势。当然，聚合件5还可以是拉力带，弹性胶条等等，本申请实施例对此不作限定。
在没有外力的作用下，聚合件5使多个支撑片2向支撑轴1聚拢，从而围绕支撑轴1形成结构紧凑且直径较小的圆柱或者类似圆柱、圆锥或者类似圆锥的结构。当第一顶推件4向远离支撑轴1的方向上顶推多个支撑片2时，聚合件5为多个支撑片2提供向支撑轴1靠拢的力以对抗第一顶推件4的顶推力，使得多个支撑片2在远离支撑轴1的位置仍旧能够保持结构的完整性，防止多个支撑片2因与支撑轴1之间脱离而散开，确保了锥度可调辊的结构完整性和稳定性。当第一顶推件4取消对各个支撑片2的顶推力，或者对各个支撑片2的顶推力减小时，多个支撑片2在聚合件5的作用下向支撑轴1聚拢以减小辊面3的锥度，从而达到锥度可调辊的锥面锥度可灵活调整的目的。
如图6所示，在一些实施例中，锥度可调辊还包括第二顶推件6，第二顶推件6用于在大体径向方向上支撑多个支撑片2的第二端22。
第二顶推件6的结构与第一顶推件4的结构相同或相类似，本申请实施例对第一顶推件4的相关描述均可以应用到第二顶推件6，本申请实施例对第二顶推件6的结构和效果不再赘述。
需要注意的是，第二顶推件6并不限于通过与支撑片2的第二端22的端部接触来顶推支撑片2的第二端22，第二顶推件6可以与支撑片2沿长度方向上靠近第二端22的一半长度范围内的任意位置接触。
上述方案通过第一顶推件4和第二顶推件6的配合，使得锥度可调辊的辊面3直径可以根据需要调节至从第一端21到第二端22逐渐减小，或者从第一端21到第二端22逐渐增大，以在不调换锥度可调辊的安装位置和方向的前提下，使得锥度可调辊能够用于对不同张力情况的带材进行两侧的松紧度调节，此外，通过第一顶推件4与第二顶推件6的相互配合，不仅能够使锥度可调辊的辊面3形成不同锥度的锥面，还可以使锥度可调辊的辊面3形成不同直径的柱面，锥度可调辊的适应性更强，应用范围更广，使用也更加方便。
如图6和图7所示，在一些实施例中，支撑片2上设有摆动支撑部23，摆动支撑部23与支撑轴1配合，以支撑支撑片2围绕摆动支撑部23在支撑轴1上摆动。
摆动支撑部23可以是设置在支撑片上的凸起，凸起可以抵在支撑轴1上，也可以通过铰接的方式与支撑轴1连接，从而使支撑片2能够围绕摆动支撑部 23在支撑轴1上摆动。
通过采用上述方案，支撑片2在支撑轴1上围绕摆动支撑部23为支点摆动，使得支撑片2的摆动范围和摆动幅度更加具有可控性，便于锥度可调辊在实际生产中应用。
如图6和图7所示，在一些实施例中，锥度可调辊还包括限位部11，限位部11设于支撑轴1上，用于限制摆动支撑部23在限位部11限定的范围内摆动。
限位部11可以是设于支撑轴1上的凹陷结构，也可以是设于支撑轴1上的用于与摆动支撑部23铰接的孔或槽；限位部11可以与支撑轴1一体成型，也可以是附加连接在支撑轴1上的一部分，当然了，限位部11也可以是绳索之类的柔性构件，该柔性构件一端连接支撑轴1，另一端连接摆动支撑部23，从而限制摆动支撑部23在柔性构件限定的范围内摆动，进一步提高支撑片2的摆动范围和摆动幅度的可控性。
如图6所示，限位部11可以设置在支撑轴1沿轴线方向的中部；如图7所示，限位部11也可以靠近支撑轴1任意一端的端部。
需要注意的是，如图6所示，摆动支撑部23与限位部11的配合结构可以设置在锥度可调辊沿长度方向的中部，如图7所示，摆动支撑部23与限位部11的配合结构也可以设置在锥度可调辊沿长度方向上靠近任意一端处，本申请实施例不做限制。
如图6和图7所示，在一些实施例中，限位部11包括设于支撑轴1上的凹槽111，摆动支撑部23的一部分在凹槽111内摆动。
凹槽111为从支撑轴1表面下凹的结构，凹槽111可以通过在支撑轴1上去除材料的方式成型，此种形式的限位部11无需占用支撑轴1表面外部的空间。
当摆动支撑部23的一部分在凹槽111内摆动时，凹槽111内壁与摆动支撑部23位于凹槽111内的部分相抵接，凹槽111为摆动支撑部23提供阻力，使得支撑片2受到第一顶推件4或者第二顶推件6的顶推时，摆动支撑部23会在凹槽111内摆动，而不容易脱离凹槽111而沿支撑轴1的轴线方向移动，从而使得支撑片2形成的辊面3在锥度可调辊轴向上的位置大体不变，以便于在固定路径上传送带材。
如图6和图7所示，在一些实施例中，摆动支撑部23和凹槽111相接触的部分均为弧形。
当摆动支撑部23随支撑片2摆动而在凹槽111内转动时，摆动支撑部23 与凹槽111之间相接触的表面更加平滑，转动阻力更小，摆动支撑部23在凹槽111内的摆动更加平稳顺畅。
如图8和图9所示，在一些实施例中，第一顶推件4包括第一顶推锥面41，第一顶推锥面41的轴线方向与支撑轴1的轴线平行，第一顶推件4沿支撑轴1的轴线方向移动，以使支撑片2的第一端21与第一顶推锥面41滑动接触并被第一顶推锥面41顶推而靠近或远离支撑轴1。
通过采用上述方案，当第一顶推件4沿支撑轴1的轴线方向移动而支撑片2在支撑轴1的轴线方向不移动时，通过设置第一顶推锥面41，可以将第一顶推件4沿支撑轴1的轴线方向的运动转化成支撑片2的摆动，即第一顶推件4沿支撑轴1的轴线运动时，第一顶推锥面41相对支撑片2滑移而使得支撑片2的第一端21逐渐靠近或远离支撑轴1。
由于第一顶推锥面41的轴线方向与支撑轴1的轴线方向平行，因此，当第一顶推锥面41的轴线方向与支撑轴1的轴线方向重合时，第一顶推锥面41的母线与支撑轴1的轴线之间的距离相等，当第一顶推件4沿支撑轴1的轴线方向移动时，第一顶推锥面41能够驱动各个支撑片2同时做幅度相等或相近的摆动运动，从而使得多个支撑片2能够在任意角度组成较为工整的锥面。
如图9所示，在一些实施例中，支撑片2上设有朝第一顶推件4凸出的第一调节部24，第一调节部24具有第一接触面241，第一接触面241与第一顶推锥面41滑动接触。
第一调节部24朝向支撑轴1凸出，第一接触面241位于第一调节部24的靠近支撑轴1的一端的端面上，第一接触面241可以是该端面的部分区域，也可以是该端面的全部。
第一接触面241可以是斜面或弧面，当第一接触面241是斜面时，第一接触面241的倾斜方向与第一顶推锥面41的倾斜方向大致相同，大致相同是指，第一顶推锥面41从第一端21到第二端22的方向上逐渐靠近支撑轴1，且支撑片2上的斜面从第一端21到第二端22的方向上逐渐靠近支撑轴1，而对于第一顶推锥面41的倾斜程度和斜面的倾斜程度具体不做限定。当第一接触面241是弧面时，弧面的轴线位于弧面远离支撑轴1的一侧。
尽管在第一顶推件4沿支撑轴1的轴线移动的过程中，第一接触面241与第一顶推锥面41之间的相对角度会发生变化，但是通过第一接触面241与第一顶推锥面41配合，依然能够起到增大支撑片2与第一顶推件4的接触面积和缓 冲支撑片2与第一顶推件4相互移动时的冲击的作用，从而减小支撑片2与第一顶推件4相互之间的磨损。
如图9所示，在一些实施例中，第一顶推件4沿支撑轴1的轴线方向与支撑轴1螺纹连接。
通过采用上述方案，当第一顶推件4相对支撑轴1转动时，能够调整第一顶推件4在支撑轴1的轴线方向的位置，从而使第一顶推件4顶推支撑片2的第一端21靠近或远离支撑轴1，而当第一顶推件4移动到任意位置时，能够通过螺纹连接进行自锁，因此不会在支撑片2的挤压下发生移动，确保支撑片2形成的辊面3锥度的稳定性。
此外，当第一接触面241与支撑轴1的轴线重合，且当螺纹连接的轴线与支撑轴1的轴线相重合时，第一顶推件4相对支撑轴1转动的过程中，第一接触面241在各个方向上相对于支撑轴1的轴线的距离相等或者基本相等，因此，通过第一接触面241控制倾斜角度的多个支撑片2从第一端21到第二端22的倾斜角度相等或者基本相等，即第一顶推件4在移动过程中顶推着各个支撑片2从第一端21到第二端22倾斜的角度相等，以使多个支撑片2组成较为规整的锥形辊面3。
如图10和图11所示，在一些实施例中，第二顶推件6包括第二顶推锥面61，第二顶推锥面61的轴线方向与支撑轴1的轴线平行，第二顶推件6沿支撑轴1的轴线方向移动，以使支撑片2的第二端22与顶推锥面滑动接触。
第二顶推锥面61的可能的结构和作用与第一顶推锥面41相同或相类似，本申请此实施例不再赘述。
通过采用上述方案，当第二顶推件6沿支撑轴1的轴线方向移动而支撑片2在支撑轴1的轴线方向不移动时，通过第二顶推锥面61，可以将第二顶推件6沿支撑轴的轴线方向的运动转化成支撑片2的摆动，即第二顶推件6沿支撑轴1的轴线运动时，第二顶推锥面61相对支撑片2滑移而使得支撑片2的第二端22逐渐靠近或远离支撑轴1。
如图11所示，在一些实施例中，支撑片2上设有朝第二顶推件6凸出的第二调节部27，第二调节部27具有第二接触面271，第二接触面271与第二顶推锥面61滑动接触。
第二调节部27的可能的结构和作用与第一调节部24相同或相类似，第二接触面271可能的结构和作用与第一接触面241相同或相类似，具体可参考对 第一调节部24和第一接触面241的相关实施例的描述，本申请此实施例不再赘述。
通过采用上述方案，支撑片2与第二顶推件6之间通过第二接触面271与第二顶推锥面61的滑动接触来实现相对运动，使得支撑片2与第二顶推件6在相对运动的过程中，各自的受力面更大，相互之间的磨损更小。
如图12和图13所示，在一些实施例中，支撑片2包括辊面成型部25和定位部26，辊面成型部25至少部分表面用于构成辊面3；定位部26位于辊面成型部25的径向内侧；支撑轴1的两端设有止挡部16，止挡部16与定位部26配合，以限制支撑片2的轴向运动。
辊面成型部25沿锥度可调辊的长度方向延伸，辊面成型部25上用于构成辊面3的部分可以是平面或者曲面，当多个辊面成型部25均匀布置时，多个辊面成型部25之间构成近似圆柱面或者圆锥面的形状。
定位部26的长度和宽度均可以小于辊面成型部25，定位部26的数量可以是一个或多个，定位部26可以安装在支撑轴1的外部，也可以在支撑轴上开槽，将定位部26安装在槽内。
例如，如图14所示，在一实施例中，支撑轴1的外壁上设置有定位槽12，定位部26的长度方向支撑轴1的长度方向平行，定位部26的宽度方向垂直于支撑轴1的长度方向，定位部26的宽度小于定位槽12的宽度，定位部26的长度小于定位槽12的长度，以使得定位部26能够装入到定位槽12内。定位部26设置有一个，定位槽12的底面沿长度方向呈圆弧形，定位部26具有与定位槽12的底面配合的圆弧形表面，当支撑片2受到第一顶推件4或第二顶推件6的顶推力时，定位部26在定位槽12内转动，转动过程中，定位部26与定位槽12之间能够始终保持圆弧面接触，定位槽12对支撑片2的支撑效果更好，且有利于支撑片2的平稳转动。
通过定位部26与定位槽12的配合，使得每个支撑片2只能在定位槽12限定的范围内移动或转动，定位槽12不仅能够在支撑轴1的周向上定位支撑片2，还能够在支撑轴1的轴向上定位支撑片2，多个支撑片2形成的辊面3更加规整，锥度可调辊的结构更加稳定。
止挡部16设置在支撑轴1的两端，两个止挡部16之间的距离可以大于定位部26的最大长度，或者多个定位部26中，沿长度方向位于支撑片2最两端的两个定位部26之间的最大距离，这使得支撑片2在摆动过程中沿支撑轴1的 轴线方向具有一定的活动空间，以便于支撑片2自由摆动而形成不同锥度的辊面3。
而当支撑片2的活动范围超出两个止挡部16限定的空间时，两个止挡部16又能够在支撑轴1的轴向上定位支撑片2，使得每个支撑片2只能在止挡部16限定的范围内摆动，在第一顶推件4或第二顶推件6的作用下，支撑片2不容易沿支撑轴1的轴向移动，锥度可调辊的结构更加稳定，多个支撑片2形成的辊面3更加规整，辊面3的锥度的可控性更强。
如图12所示，在一些实施例中，定位部26在垂直于支撑轴1轴线方向的宽度小于辊面成型部25的宽度。
辊面成型部25用于构成辊面3，定位部26用于与支撑轴1上的定位槽12配合，因此，定位部26比辊面成型部25更加靠近支撑轴1，即以支撑轴1的轴线为轴心时，辊面成型部25所在处的圆周直径更大，定位部26所在处的圆周直径更小，因此，当定位部26在垂直于支撑轴1轴线方向的宽度小于辊面成型部25的宽度时，在支撑片2形成的辊面3直径减小的过程中，相邻定位部26不可能先于相邻的辊面成型部25接触，从而使得相邻支撑片2的辊面成型部25能够自由靠近或远离，锥度可调辊的辊面3直径的大小取决于相邻的辊面成型部25之间的间距，辊面成型部25的直径和锥度调节的灵活性更大，调节范围更广。
如图13和图14所示，在一些实施例中，支撑轴1包括内轴13和外轴14，外轴14沿其轴向设有通孔141，内轴13设于通孔141内并转动支撑外轴14，支撑片2连接于外轴14上。
内轴13可以是台阶轴，外轴14的通孔141可以是台阶孔，内轴13与外轴14之间可以在周向上转动配合，也就是说，可以仅仅是外周转动，内轴13不动；也可以仅仅是内轴13转动，而外轴14不动，这种配合方式可以通过内轴13与外轴14之间的间隙配合实现，也可以通过在内轴13与外轴14之间安装轴承15来实现，此种安装状态下，内轴13可以固定安装在外界设备上，而外轴14在带材的摩擦力下相对内轴13转动，以传送带材，并对带材进行张紧，减小对带材的撕扯，防止对带材造成损坏。
如图12所示，在一些实施例中，第一顶推件4设于外轴14与内轴13之间，支撑片2的至少部分贯穿外轴14的侧壁而与第一顶推件4滑动接触。
通过采用上述方案，第一顶推件4设置在内轴13与外轴14之间，所以不 会占用支撑轴1与支撑片2之间的空间，使得支撑片2在支撑轴1外部可以进行更大范围的锥度调节。
根据本申请实施例的另一方面，提供了一种带材传送装置，包括上述主题任一实施例中的锥度可调辊。
通过采用上述方案，带材在传送过程中的两侧松紧度可以通过锥度可调辊进行调节，减少带材出现打皱、变形和撕裂的问题。
综上所述，本申请实施例通过第一顶推件4顶推多个支撑片2，使得多个支撑片2形成的辊面3直径从第一端21到第二端22的逐渐变化而形成锥面，当该锥度可调辊用于传送带材时，可将辊面3的直径较大的一端用于接触带材较松的一侧，辊面3的直径较小的一端用于接触带材较紧的一侧，带材较松的一侧与辊面3之间接触的面积较大，较紧的一侧与辊面3的接触面积较小，从而使带材较松的一侧在锥度可调辊上被张紧，平衡带材宽度方向两侧的松紧度，减小带材两侧的张力差，从而减少带材打皱和撕裂变形的问题的发生。
