Description

technical field [0001] The invention relates to the field of printing and binding machinery, in particular to a paper feeding control method and device for a paper table of a folding machine. Background technique [0002] During the working process of the folding machine, the paper feeding system is the first gate of the whole machine, which directly affects the running speed and working efficiency of the machine. Whether it can pass the subsequent folding action normally is an important prerequisite for the normal operation of the machine. [0003] At present, the operation of the electromagnetic valve of the paper feeding system of the folding machine is generally based on the speed of the machine's operating motor. After a series of processing, the operating frequency of the electromagnetic valve is obtained after the operating speed of the machine is processed, and the position signal of the paper does not directly participate. Operation, in this way, the working freque...

Problems solved by technology

[0003] At present, the operation of the electromagnetic valve of the paper feeding system of the folding machine is generally based on the speed of the machine's operating motor. After a series of processing, the operating frequency of the electromagnetic valve is obtained after the operating speed of the machine is processed, and the position signal of the paper does not directly participate. Operation, in this way, the working frequency of the paper feeding solenoid valve depends on the stability of the machine's running speed. When the switching frequency characteristics of the synchronous test decrease, and there is relative motion between the transmission mechanism and the supporting mechanism, the solenoid valve will work. The frequency is not consistent with the operating frequency of the machine, resulting in a series of problems such as paper collision, unstable paper spacing, and machine false alarm blocking. The distance between the papers should be as small as possible, there should be no broken chapters, and the paper surface should be flat and tidy. When the pile of paper cannot meet the requirements, a series of problems as mentioned above will also appear.
