The invention discloses a tearing line device for packing bag, including a tearing line blade and a bottom plate set up and down. The tearing line blade is mounted on the blade seat. The blade seat is moved up and down by the cylinder, and the bottom plate is fixed. The feature is that the upper surface of the bottom and the tearing line blade are designed with a slope, and the low end of the slope is set. The bag body is introduced into the slope, and the high end of the slope is provided with the guide roll of the bag, the bag body is introduced into the slope, the bag body is introduced into the guide roll and the bag body leads to the guide roll, so the direction of the bag body is the same as the slope direction. The center distance of the bag body is introduced into the guide roll and the center distance of the guide roller of the bag body is L1, the surface of the slope is set up. With active liner, the active liner slips up and down along the slope direction, the length of the active liner is L2, and the difference between L1 and L2 is greater than the distance between the bag feeding of the bag when the bag machine works. The invention solves the technical problems of the single layer tearing thread of the packaging bag, and has simple structure and ingenious design.

包装袋打撕裂线装置
本专利技术涉及一种对包装袋打撕裂线的包装袋打撕裂线装置。
技术介绍
现有技术,制袋机生产的包装袋如果要打撕裂线,往往会在包装袋的上下两层同时打上撕裂线。要解决包装袋单层打撕裂线的问题,制袋机需要包装袋的袋体进行单层展开,在单层展开时打上单层撕裂线,或包装袋在制袋完成后利用手工进行;但关键的是,目前包装袋的制袋机生产大部分是利用双层料的薄膜卷材来进行生产,生产过程中没有袋体单层展开的工序也不能进行单层展开。所以,要进行包装袋的单层打撕裂线,首先不能用双层料的薄膜卷材来生产包装袋,同时需要制袋机进行特殊设计,这就会给包装袋的生产带来极大不便;而手工进行单层打撕裂线则效率太低。
