如图1及图2所示，本实用新型的分段智能电磁加热辊，包括辊体11、分段设置在该辊体11上的若干感应线圈114、固定支撑所述感应线圈114的支撑结构以及连接并分段控制该感应线圈114工作的控制装置12；该辊体11能够形成主动发热对薄膜进行加热；该感应线圈114工作时能产生高频的交变磁场，并切割辊体，使该对应位置的辊体11上产生感应电流形成主动发热。该控制装置12能够实现分段智能联动控制，使得加热过程的温度和宽度可以实现全自动精准控制，提高了该分段智能电磁加热辊操控安全性以及节能程度。
该辊体11包括固定在该辊体11的支座111、设置在该支座111上的辊筒112以及穿设在该辊筒112中与该支座111固定连接的芯轴113；该若干感应线圈114并排套设在该芯轴113上。该支座111可用于固定该辊筒12，其包括设置在该辊筒112两端的两个支撑角，该支撑角分别与芯轴113两端固定连接。该辊筒112采用导磁性金属材质制成，其可以呈中空圆柱状，且该辊筒112内部直径大于该芯轴113的直径，使得该辊筒112能够进行转动。该芯轴113为该感应线圈114的支撑结构；采用绝缘性材质制成，且该绝缘性材质为非导磁性高强耐高温材料，该芯轴113从该辊筒112穿出，其长度大于该辊筒112的长度。该芯轴113上设有供该感应线圈114绕设的若干凹槽，该凹槽可用于固定感应线圈114使感应线圈114的位置不会因外力或温度变化而变化，再通过直接外引到控制器。
该辊筒112内侧壁与该感应线圈114之间设有隔热保温层。该隔热保温层可以隔绝辊筒加热后传导过来的热量，以保护感应线圈114，避免该感应线圈114受热老化，还有起到绝缘的的效果。优选地，该隔热保温层的厚度可以为5mm~30mm。
该感应线圈114采用高温铜线或者多股漆包线制成，该感应线圈的数量可以是两组、三组、四组、五组或者多组；在本实施例中，优选地，该感应线圈114的数量为三组；该若干感应线圈114并排套设在该芯轴113上，且在其工作时产生高频交变磁场，并切割辊筒11，从而使该辊筒11产生局部微小的涡流，并依靠自身内阻主动发热。该由于该感应线圈114自身不发热，因此流过该感应线圈114的电流所转换的能量几乎全部用于热能转换，能量损耗极小其电热转换率高达98%，节能效果比传统辐射加热高出40%以上。该辊体主动发热、功率密度大小可调，热响应快，瞬间就能达到所需温度，并能根据转速快慢调整功率密度，保持辊面的温度精确控制在±1℃以内该感应线圈114与辊筒之间留有间隙，因此该感应线圈114不与辊筒接触从而可以避免了短路、漏电的危险，提高该设备安全性能。

该智能电源控制器121为IGBT式数字智能加热控制器与PLC主控芯片预设控制程序实现实时的智能化控制；其包括嵌入式控制软件、IGBT功率模块、数字信号处理器、时间控制器、温度控制器。即PLC根据当前设定的参数提供加热信号给智能电源控制器，智能电源控制器的数字信号处理器进行信号的数字化处理，并实时采集来自温度控制器的实时信号，进行瞬时处理，通过调节智能电源控制器121的开启数量、加热输出功率大小或者加热时间占空比等参数，来实现薄膜辊发热段的热量均衡分布，实现加热温度按照预设温度曲线控制。
该分段智能电磁加热辊可以分段智能控制，分区调节功率大小及加热时间占空比，使加热能适应不同加热宽度要求。当薄膜宽度较小时，只需启动位于中间的感应线圈114进行工作，其余感应线圈114不进行工作或进行间断工作，薄膜宽度以外的薄膜辊面不发热既可达到二次节能，又可解决无法变幅宽导致两侧温度超高的问题：薄膜经过前，在辊体11的轴向上从一端到另一端发热量一致，而薄膜经过时，中间有薄膜区会带走大部分热量，出现宽度方向两头热，中间底的现象。分段智能控制能可以对薄膜覆盖区的辊体11表面温度进行精确控制，保证在薄膜覆盖区辊体轴方向温度的均匀性，从而保证薄膜受热均匀，收缩/烘干一致性好。

该支撑板116的材质为绝缘性材质；且该绝缘性材质为非导磁性高强耐高温材料，其尺寸和弧度与该锟体11相适配。该支撑板116上设有固定该感应线圈114的若干凹槽，可用于固定该感应线圈114使该感应线圈114的位置不会因外力或温度变化而变化。
可以理解的，以上实施例仅表达了本实用新型的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本实用新型专利范围的限制；应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，可以对上述技术特点进行自由组合，还可以做出若干变形和改进，这些都属于本实用新型的保护范围；因此，凡跟本实用新型权利要求范围所做的等同变换与修饰，均应属于本实用新型权利要求的涵盖范围。
