1. Improper operation of the transverse cutting machine directly affects the size of the carton
Improper operation of the cross-cutting machine will directly affect the size of the carton, and the accurate size is one of the most important indicators to measure the quality of the carton.If the size of the carton is not allowed, it will directly lead to the carton scrap, causing a huge waste of production.
2. the working principle of the computer cross-cutting machine
Computer cross cutting machine mainly has two main: DC motor drive control system and AC servo motor control system control system to the computer according to the order set shear length and the meter wheel and the motor position to determine the shear mode, and calculate the time parameters to control the transmission to the drive system, according to these parameters drive system control output, control the motor to achieve the purpose of automatic cutting.
The shear speed of the control system must automatically track the feed speed of the shear material, the system can detect the incoming speed and the length of the cardboard (the pulse number of the cardboard) in real time, and compensate the shear speed in the adjustment link to achieve the purpose of accurate cutting.The running speed of the cross-cutting machine is synchronized by the speed wheel pressing on the cardboard to reach the tile line speed.Therefore, the speed measuring wheel is the key factor affecting the cutting size accuracy of the transverse cutting machine.
3. to ensure the size of the carton, how to adjust the cross-cutting machine?
(1).The gap between the speed measurement wheel and the roller greatly affects the accuracy of the cutting length. The gap should be adjusted at about 1mm to ensure that the cardboard should not be too tight or too loose after the speed measurement wheel, otherwise the cutting length error will be caused.
(2). The transverse cutting machine control system shall have the cutting length compensation function to compensate for the system error and the random error due to human factors.
（3）The knife shaft steel needs special treatment to ensure smooth operation at high speed.Automatic oil pump lubrication system and gear adopt no pless structure to eliminate drive error and achieve accurate size cutting.
（4）In the actual production, the factor affecting the transverse cutting machine is the speed of cardboard.When the double-sided machine drive skid phenomenon, will cause the cardboard speed fluctuation, seriously affect the cardboard cutting accuracy.
Therefore, it is necessary to solve the problem of cardboard skid first to ensure the accuracy of cutting length and size under the condition of stable cardboard operation.
