Web Guide System Used

The basic action flow of the automatic paper servo guide system is: manual paper feed reaches the paper feed port → the paper detection guiding sensor detects the paper → closes the paper feed path (forms the reference plane behind the friction wheel set) → uses the guide controller to control The guiding force switching mechanism is switched to the guiding force→friction wheel group →paper→paper top is rotated under the action of the guiding baffle→top of the page, the smear sensor detects that the paper is positive→the paper feed channel is open→the corrective force is switched to the paper feed Strength → Paper entry, guide is completed.

The above is only a successful paper guide process under ideal conditions. Actually, due to the special flexible medium of paper, its thickness, length, width and material vary widely, which has different effects on the work of the guide system. There are many mechanical indexes related to the paper and the guide system. . Including the thickness, tightness, smoothness, hardness, strength, etc. of the paper is a common performance. The strength properties include static strength and dynamic strength.

The static strength includes: tensile strength, bursting resistance, tearing degree, folding resistance, stiffness and the like. This mechanical property varies from medium to medium, so the design of the corrective action system must take into account the properties of the paper and the instability it brings. It is only possible to experimentally test the effect of the guide system on different papers, and adjust the parameters such as the action definition and the operation duration in the software control according to the processing effect, and also need to consider the processing method when the system fails to correct the paper. According to the aforementioned definition of the key component action of the guide system, a more complete automatic paper servo guide system workflow.
