使用时， 托辊 2与送料对辊 3中位于背面的送料辊 31位于同一平面上， 共 同承托带料， 送料主动辊带动带料前移， 同时送料主动辊会根据理论传输长度 设定一转动圈数， 当达到该数值时便停止送料， 送料对辊 3 夹持着带料向下游 传输， 需要割角是， 割刀便在带料上割出所需角度， 在带料传输过程中， 托辊 2 端部的编码器 4也同时在记录数据， 该数据是带料传输的实际长度， 当实际长 度与理论长度存在差异时， 编码器 4会将该差值传输给控制系统， 控制系统便 控制送料主动辊继续送料， 补偿该差值， 确保传输长度的准确性。  In use, the idler roller 2 and the feed roller 31 on the back side of the feed-to-roller 3 are located on the same plane, and jointly support the strip material, and the feed-feeding roller drives the strip material forward, and the feed-feeding roller is set according to the theoretical transport length. Rotating the number of turns, when the value is reached, the feeding is stopped, the feeding to the roller 3 holds the strip to the downstream, and the cutting angle is required, the cutter cuts the required angle on the strip, during the belt conveying process. The encoder 4 at the end of the roller 2 is also recording data at the same time. The data is the actual length of the tape transport. When the actual length is different from the theoretical length, the encoder 4 transmits the difference to the control system, and controls The system controls the feed drive roller to continue feeding, and compensates for the difference to ensure the accuracy of the transmission length.
本发明不局限于上述具体的实施方式， 本领域的普通技术人员从上述构思 出发， 不经过创造性的劳动， 所作出的种种变换， 均落在本发明的保护范围之 内。  The present invention is not limited to the specific embodiments described above, and various changes made by those skilled in the art from the above-described concept, without departing from the inventive scope, fall within the scope of the present invention.
