阅读说明：本技术 一种切割机构及覆膜装置 (Cutting mechanism and tectorial membrane device ) 是由 裴辉 沈锦平 张兴旺 于 2019-09-29 设计创作，主要内容包括：本发明涉及工件覆膜技术领域,公开了一种切割机构及覆膜装置。切割机构用于切断工件尾部边缘的保护膜,包括转盘及发热丝,所述发热丝设置于所述转盘的偏心位置处,所述转盘能够以自身的轴心为中心转动,并带动所述发热丝旋转,以将所述保护膜切断。发热丝旋切保护膜时,即便切到工件尾部的局部位置,也不会对工件尾部的位置造成持续下压的力,能够避免工件硬划伤,且发热丝不会受到持续拉力,增加了发热丝的使用寿命。覆膜装置通过上述切割机构可以减少工件的损伤,提高发热丝的使用寿命。(The invention relates to the technical field of workpiece film covering, and discloses a cutting mechanism and a film covering device. The cutting mechanism is used for cutting off the protective film on the edge of the tail of the workpiece and comprises a rotary table and a heating wire, wherein the heating wire is arranged at the eccentric position of the rotary table, and the rotary table can rotate by taking the axis of the rotary table as the center and drive the heating wire to rotate so as to cut off the protective film. When the heating wire rotary-cut protective film is used, even if the local position of the tail part of the workpiece is cut, the force for continuously pressing down the position of the tail part of the workpiece can not be caused, the hard scratch of the workpiece can be avoided, the heating wire can not be continuously pulled, and the service life of the heating wire is prolonged. The film laminating device can reduce the damage of the workpiece through the cutting mechanism and prolong the service life of the heating wire.)
