Tobacco cutter lower knife door falling pressure alarm device and alarm method

Abstract

The invention relates to a tobacco cutter lower knife door falling pressure alarm device and method. The tobacco cutter lower knife door falling pressure alarm device comprises a lower knife door, a lower knife door seat, a pressure sensor and a PLC. The two sides of the upper portion of the lower cutter door seat are each provided with a pressure sensor, and each pressure sensor is used for detecting the pressure of the lower cutter door on the corresponding side. The lower knife door is fixedly connected with the lower knife door seat through a safety screw, and each pressure sensor is in electric signal connection with the PLC. Through the combination with actual production, the problems that the lower knife door of the tobacco cutter is not completely disengaged due to some uncontrollable factors in the tobacco cutting process, the tobacco cutting width is changed, and even tobacco cutting sheet running is caused can be effectively solved; and the shredding width stability control capability can be improved, and the tobacco shred quality is improved.

Description

technical field [0001] The invention belongs to the technical field of shredders, and in particular relates to a pressure alarm device and an alarm method for the falling off pressure of a lower knife door of a shredder. Background technique [0002] In the structure of the knife door system of the SQ215D wire cutting machine currently used in the tobacco industry's silk workshop, the lower knife door is connected to the lower knife door seat through four safety screws, and a safety proximity switch is set between the lower knife door and the lower knife door seat. The lower knife door seat is connected with the left and right wall panels with screws and positioning pins to form the lower knife door assembly. [0003] When the wire cutter is running, if the material contains hard objects and is cut, the cutting force is too large, the shearing force on the four safety screws is greater than the strength of the safety screws, the four safety screws are cut off, and the lower ...
