In the hydration production of diapers, diapers, trousers, and sanitary napkins, it is often encountered to cut products or materials such as cotton core layers, small packages, buckles, etc. according to the specified size, and even need to be cut off. The product or material is quickly removed for the next cycle. The existing variable speed cutter device can only realize the production of one series of products. If the equipment is replaced, it is necessary to remove the whole set of cutting device and replace it with a new one. The process is very cumbersome and time consuming. In addition, a set of cutter devices is expensive, and if it is necessary to produce a plurality of series products, it is necessary to increase the manufacturing cost.

发明内容Summary of the invention

When the rotating shaft of the anvil roll and the knife roll is fixed to the circular gear pair, the anvil roll and the knife roll are rotated at a constant speed to cut off the product or material, and this can be used in some environments where no shifting is required. When the rotating shafts of the anvil roll and the knife roll are respectively fixed to the non-circular gear pair, the knife roll rotates at a constant speed, and the anvil roll corresponding to the knife roll is rotated in accordance with the set shape of the non-circular gear pair.

作为本发明的另一种具体实施方案，上述齿轮副由若干副非圆齿轮副组成，其只能实现变速运动，无法实现匀速运动，工作原理与上述相同，在此不再赘述。As another specific embodiment of the present invention, the gear pair is composed of a plurality of pairs of non-circular gear pairs, which can only realize the shifting motion, and cannot achieve uniform motion. The working principle is the same as the above, and details are not described herein again.

进一步的，本发明还包括用于安装变速组件的齿轮箱。变速组件相对于旋转切刀组件的位置是可移动的。更进一步的，所述砧辊在靠近刀辊一侧的材料切断区内的第一角速度，小于或者等于远离刀辊一侧的材料移送区上的第二角速度。Further, the present invention also includes a gearbox for mounting the shifting assembly. The position of the shifting assembly relative to the rotating cutter assembly is movable. Further, the first angular velocity of the anvil roll in the material cutting zone near the side of the knife roll is less than or equal to the second angular velocity on the material transfer zone away from the side of the knife roll.

本发明与现有技术相比，具有如下优点：Compared with the prior art, the invention has the following advantages:

本发明通过对变速组件进行改进，其包括至少两副齿轮副，齿轮副中包含至少一副非圆齿轮副，并且变速组件中的任意一副齿轮副与砧辊、刀辊对应可拆卸式连接。采用上述技术方案，使用一套切刀装置就能实现多个系列产品的生产，调试时仅需调整齿轮箱的位置即可，节省了设备成本并缩短产品的改码时间。上述结构彻底改变了目前行业所面临的设备改码难度大、周期长、成本高的通病，并可结合辅助的控制装置，实现主控制系统的一键改码功能。本发明具有结构简洁，改码方便，制造成本低的优点，符合实际生产需求。The invention improves the shifting assembly, comprising at least two pairs of gear pairs, wherein the gear pair includes at least one pair of non-circular gear pairs, and any one of the gear units is detachably connected to the anvil roller and the knife roller . With the above technical solution, the production of multiple series of products can be realized by using one set of cutter device, and only the position of the gear box needs to be adjusted during debugging, which saves equipment cost and shortens product recoding time. The above structure completely changes the common problems faced by the industry at present, such as difficulty in recoding the device, long cycle, and high cost, and can be combined with an auxiliary control device to realize the one-key code changing function of the main control system. The invention has the advantages of simple structure, convenient code change and low manufacturing cost, and meets the actual production requirements.
