Finished paper winding self-detecting edge pressing device

Abstract

The invention relates to the technical field of papermaking winding machines, and discloses a finished paper winding self-detecting edge pressing device which comprises a shell, an electromagnet is fixedly connected to the inner wall of the middle of the shell, an extension spring is fixedly connected to the inner wall of the middle of the shell, a pressing block is fixedly connected to the bottomof the extension spring, a first magnetic block is fixedly connected to the inner wall of the middle of the pressing block, a limiting groove is formed in the middle of the shell, and the inner wallof the middle part of the shell is fixedly connected with a detecting rod. According to the finished paper winding self-detecting edge pressing device, a movable block is driven by a contact to operate, a dielectric plate is driven by the movable block to operate, and a positive plate, a negative plate and balls are matched for use, so that the effect of automatically detecting paper wrinkle or edge warping is achieved; and paper slides through the top of the contact, the paper with wrinkles or curled edges extrudes the contact outwards, the movable block drives the dielectric plate to move bya large margin, the voltage between the positive plate and the negative plate is gradually increased, and the working voltage of a piezoresistor is reached at the moment, so that paper wrinkle or curled edges is detected.

Description

technical field [0001] The invention relates to the technical field of papermaking winders, in particular to a finished paper winding self-test edge-holding device. Background technique [0002] The winding machine is the equipment for the final winding and packaging of the finished paper. The work of the winding machine is to rely on the friction of the winding roller to drive the paper to wind evenly. The winding machine makes the paper more evenly wound on the paper tube. In fact, it can meet the needs of different papers. When the existing paper roll machine is working, there is no matching edge-holding mechanism or the edge-holding mechanism is not perfect, which causes the warped edge of the finished roll paper and affects the finished roll paper. quality. [0003] Existing equipment requires a special person to check the winding situation in real time, and press the edge of the paper roll with warping phenomenon by holding the pressure rod to ensure the smooth windin...
