An online real-time deviation correction device and method for paper edge height

Abstract

The invention discloses an online real-time deviation-correcting device and method for the deckle edge height. The device comprises a front deckle edge deviation-correcting device and a rear deckle edge deviation-correcting device. Servo motors are installed on flange bases, and the flange bases are connected with small wallboards through screws and installed on shafts through first bearings. The servo motors are connected with the shafts through couplings. Excentric sleeves and the shafts are fixed through check rings and screws and can rotate together. Each excentric sleeve is connected with a paper guide roller through a second bearing. Each excentric sleeve is divided into a front section and a rear section, wherein one section and the corresponding shaft are concentric, and the other section and the corresponding shaft are excentric. When the two paper guide rollers are installed on the excentric sleeves through the second bearings, the sections, excentric with the shafts, of the paper guide rollers are in an excentric state so that the deviation-correcting effect can be achieved. Due to installation of the two deviation-correcting devices at the corresponding positions, online real-time deviation-correcting of the deckle edge height can be realized. The front deckle edge deviation-correcting device and the rear deckle edge deviation-correcting device are driven by the independent servo motors correspondingly, do not interfere with each other and can be adjusted independently.

Description

technical field [0001] The invention belongs to tobacco machinery, and relates to an online real-time deviation correction device and a deviation correction method for paper edge height in the production process of a cigarette machine. Background technique [0002] In the cigarette making machine, before the paper tape enters the bong and shredded tobacco is rolled into cigarettes, the height of the paper edge needs to be detected. If there is a difference between the paper edge height and the set value, it will affect the glue quality of the cigarette and the overlap of the cigarettes. quality. At present, the deviation correction method for the height of the paper edge of the cigarette machine is to adjust the paper tape to a proper position by forcing the limit block manually. [0003] Although this correction method is simple, it can only be adjusted manually before starting the machine, and cannot realize online dynamic adjustment, and the adjustment effect is poor, an...

Problems solved by technology

[0003] Although this correction method is simple, it can only be adjusted manually before starting the machine, and cannot realize online dynamic adjustment, and the adjustment effect is poor, and it is easy to cause damage to the paper edge, and cigarette problems such as burrs, breakage, and wrinkles appear, especially in today's high-speed In the cigarette making machine, the double-bong technology has been widely used, and the height of the front and rear paper tapes needs to be corrected in time. The manual method is completely unsuitable for the production needs of the high-speed cigarette making machine.
