具体实施方式
以下结合附图对本实用新型作进一步详细说明。
实施例1，一种卷芯管，参见说明书附图2，若卷芯管的外表面呈圆柱状平滑过渡，则在卷取如薄膜等物料4时，物料4的起始端铺在卷芯管表面使得后续的物料4卷绕时被该起始端垫伤。
参见说明书附图3，在卷芯管的表面设置一台阶部2，使得台阶部2上方直径大于台阶部2下方直径。台阶部2的高度设置为被卷取 物料4的单层料厚。使得物料4铺在台阶部2下方时，物料4的外表面与台阶部2上方平齐，以此有效消除物料4在卷曲时容易出现的垫伤、折痕缺陷。
参见说明书附图1，台阶部2沿卷芯管的轴向设置在卷芯管的表面。台阶部2的下方向下继续延伸出切刀槽3，并保证切刀槽3的宽度足够供切刀穿过。在卷取物料4前，将物料4起始端覆盖在台阶部2上，并通过切刀与切刀槽3的配合对物料4起始端进行裁切。保证在裁切后，物料4起始端与台阶部2平整拼接，避免起始端与台阶部2出现缝隙。
实施例2，一种卷芯管，参见说明书附图4、5，包括管体1、台阶部2、切刀槽3。切刀槽3的宽度为1～1.5mm，深度为2mm。在切刀槽3内设置有弹性夹片5，弹性夹片5的上方一体设置有延伸部6。弹性夹片5的厚度为0.3～0.6mm，延伸部的厚度为0.8～1.2mm。保证弹性夹片5的厚度小于延伸部6的厚度。使得延伸部6的变形抗力大于弹性夹片5的变形抗力。保证在弹性夹片5变形时，延伸部6保持稳定的固定在管体1上。弹性夹片5与延伸部6大致呈“7”字形设置。延伸部6贴覆在管体1的表面，且延伸部6通过其下方的凸条7与管体1表面的凹槽8插接，其中凸条7与凹槽8保持紧配，通过静摩擦力将延伸部6固定在管体1表面。弹性夹片5与延伸部6通过一尖锐折角连接，使得其还能作为辅助刀口与切刀配合，提高切刀对物料的裁切能力。
弹性夹片5置于切刀槽3内，弹性夹片5的下端倾斜使其靠近台 阶部2。参见说明书附图6，使得物料4在经切刀裁切、带入切刀槽3后，弹性夹片5与台阶部2形成卡扣卡住物料4端部，对物料4起与固定效果。同时利用弹性夹片5的楔形倾斜使其有效固定物料4，避免物料4退出切刀槽3。在弹性夹片5以及台阶部2的相向侧设置防滑纹9，以加强弹性夹片5、台阶部2对物料4的夹持力。
本具体实施例仅仅是对本实用新型的解释，其并不是对本实用新型的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本实用新型的权利要求范围内都受到专利法的保护。
