技术领域Technical Field
本实用新型涉及塑料袋生产技术领域，具体涉及一种用于塑料袋生产的打孔装置。The utility model relates to the technical field of plastic bag production, in particular to a punching device used for plastic bag production.
背景技术Background Art
中国专利公开了一种用于塑料袋生产的折边打孔装置(公开号：CN218615704U)，包括加热刀头、刀座、原料辊和收卷辊；负压固定机构左端面开设有打孔槽，所述打孔槽与加热刀头的位置对应设置；所述打孔槽与气道的一端连通，所述气道开设在负压固定机构内，所述气道的另一端通过密封机构密封；所述密封机构包括密封板和滑杆，所述密封板上下滑动安装在滑杆上，所述滑杆焊接固定在所述负压固定机构的上端面，所述滑杆上套装有弹簧，所述滑杆顶端焊接固定有限位块，此装置利用打孔座的改进，将打孔完成时的打孔座实现负压对塑料袋进行吸引固定，结构原理简单，实用性强，有效保证了塑料袋打孔折边的精度，且无需额外动力源，实用性强；A Chinese patent discloses a folding and punching device for plastic bag production (publication number: CN218615704U), comprising a heating blade, a blade seat, a raw material roller and a winding roller; a punching groove is provided on the left end face of a negative pressure fixing mechanism, and the punching groove is arranged corresponding to the position of the heating blade; the punching groove is connected to one end of an airway, the airway is provided in the negative pressure fixing mechanism, and the other end of the airway is sealed by a sealing mechanism; the sealing mechanism comprises a sealing plate and a sliding rod, the sealing plate is slidably mounted on the sliding rod up and down, the sliding rod is welded and fixed to the upper end face of the negative pressure fixing mechanism, a spring is sleeved on the sliding rod, and a limiting block is welded and fixed to the top end of the sliding rod. This device utilizes the improvement of the punching seat to realize negative pressure on the punching seat when the punching is completed to attract and fix the plastic bag. The structural principle is simple, the practicability is strong, the accuracy of the punching and folding of the plastic bag is effectively guaranteed, and no additional power source is required, the practicability is strong;
上述装置在塑料袋收卷的过程中，由于塑料袋的收放程度受到辊上塑料袋卷厚度的影响，容易随着塑料袋数量的变化，每一次打孔位置会逐渐产生偏差，并且由于塑料袋的收放程度难以通过电机直接通过转速控制，导致可能出现放了多余的一段塑料袋，导致塑料袋不处于平直状态，此状态下的塑料袋被吸附，必然导致褶皱，可能使得打孔变形。During the process of plastic bag rewinding, the above-mentioned device will gradually deviate from the position of each punching because the degree of retraction and expansion of the plastic bags is affected by the thickness of the plastic bag roll on the roller. In addition, since the degree of retraction and expansion of the plastic bags is difficult to control directly through the speed of the motor, an extra section of plastic bags may be placed, causing the plastic bags to be not in a straight state. The plastic bags in this state will be adsorbed, which will inevitably lead to wrinkles and may cause deformation of the punching holes.
