Packaging bag cutting device capable of preventing overload operation and adjusting cutting radius

Abstract

The invention relates to the technical field of packaging bag cutting, and discloses a packaging bag cutting device capable of preventing overload operation and adjusting the cutting radius. The packaging bag cutting device comprises a rotating shaft, wherein the top end of the rotating shaft is in transmission connection with a motor; a cutting disk is fixedly mounted on the surface of the rotating shaft; coils are fixedly mounted on the surface of the cutting disk; magnetic blocks are arranged on the edge of the cutting disk; a limiting block is fixedly connected to the bottom end of each magnetic block; sliding cavities are formed in the surface of the cutting disk; and an electrorheological fluid is placed in each sliding cavity. According to the packaging bag cutting device capable ofpreventing overload operation and adjusting the cutting radius, the cutting radius can be adjusted to adapt to different types of packaging bags, so that the practicability of the device is improved,and unnecessary economic cost can be reduced; and the device is subjected to speed limiting during overload operation, so that the service life of the device is prevented from being shortened due toa too high operating speed of the device, and processed workpieces are prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of packaging bag cutting, in particular to a packaging bag cutting device that prevents overload operation and can adjust the cutting radius. Background technique [0002] At the end of the production of packaging bags, it is usually necessary to use a cutting device to cut the packaging bags into the required size for easy use, but most cutting devices cannot adapt to many types of packaging bags, and multiple cutting devices are required when producing various types of packaging bags , causing unnecessary economic waste, and in the process of cutting, if the equipment is overloaded, it will not only reduce the service life of the equipment itself, but also reduce the accuracy of the cut packaging bags and reduce the processing quality. [0003] In order to solve the above problems, the inventor provides a packaging bag cutting device that prevents overload operation and can adjust the cutting radius. Nece...
