Description
Technical Field
The invention relates to a knife grinder, in particular to an automatic grinding device for a cigarette making and plug assembling machine blade.
Background
The high-speed filter tipping equipment is important equipment in cigarette making and is used for making double-length cigarettes made by a cigarette making machine into filter cigarettes. The cigarette making machine transmits the cigarette with double length to the cigarette inlet drum of the cigarette making machine, and then the cigarette is cut into two cigarettes with equal length, the two cigarettes are separated by a certain distance, the filter section is placed in the middle to form a cigarette group, Chinese cypress paper pieces are stuck on the cigarette group, the cigarette is twisted and connected into double-length filter cigarettes, the cigarette is cut into two single-length filter cigarettes, the double-row filter cigarettes are arranged into a single row with the filter facing the same direction by the manipulator, unqualified cigarettes are eliminated after detection, and finally the finished filter cigarettes are output to the cigarette making machine.
At present, when double length filter tip cigarettes are cut through the second, the knife sharpening grinding wheel at the second cutting position is manually adjusted, the adjusting mode is seriously influenced by experience factors of operators, the operators with insufficient experience cannot timely find the opportunity of manually adjusting the knife sharpening grinding wheel, and the position of the grinding wheel can be adjusted when the cigarettes with defects are frequently found. This mode of regulation is passive and has two disadvantages:
firstly, when the cutter becomes smaller along with grinding, the cutter cannot be ground in time, so that the cutter is not sharp enough, and the defect of irregular cut of cigarettes is caused;
secondly, when the grinding angle between the grinding wheel and the cutter changes along with the operation of the equipment, the cutter is ground too fast or too slow, so that burrs appear at the cut part of the cigarette and the quality hidden danger is caused.
In addition, in the normal production process, the feeding adjustment of the second cutting grinding wheel depends on the manual adjustment of the feeding amount by an operator, the feeding amount completely depends on the experience of the operator, the accurate control cannot be realized, and the loss transition phenomenon of the second cutting knife exists, so that the waste is caused.
