Paper feeding method of slot machine

Abstract

The invention discloses a paper feeding method of a slot machine. The paper feeding method is characterized in that a programmable logic controller (PLC) controls a servo motor which drives a paper feed roller, and the paper feed roller drives slot paper to proceed or draw back; during a paper slotting process, and during switch between a small slot and a large slot of a stator, the PLC controls the servo motor to drive the paper feed roller to rotate reversely so as to drive the slot paper to draw back until a paper withdraw distance ranging from 0.1mm to 0.2mm is reached; during the next paper feeding process, the PLC controls the servo motor to drive the paper feed roller to rotate positively so as to drive the slot paper to proceed until a paper proceeding distance is reached for cutting through a cutter, and the paper proceeding distance is equal to the sum of the set width of a slot paper bar plus the paper withdraw distance. According to the paper feeding method, improvement and guarantee of product quality are facilitated, protection of the slot machine is facilitated, and the failure rate of devices is reduced.

Description

technical field [0001] The invention relates to a paper machine with a servo paper feeding slot, in particular related to the paper feeding mode of the servo paper feeding slot machine. Background technique [0002] The working principle of the existing servo paper feed slot paper machine is roughly as follows: the motor power is transmitted to the reducer through the belt, and the reducer passes a part of the power through the synchronous belt and the drive shaft to control the cutter to cut the slot paper and the ejector rod to the stator core. The cut slotted paper block is pushed inside; the other part of the power of the reducer passes through the indexer and the gear set to control the number of slots for the slotted paper of the stator core. The stator core is designed with large and small slots. When the large slot is filled with paper and the small slot is not, the small slot will swing with the paper guide plate, so that the slot paper will be cut into strips with ...

AI Technical Summary

Problems solved by technology

The above-mentioned grooved paper strips that have been cut out sometimes enter the iron core and affect the quality of the product. If there are a large number of grooved paper strips, sometimes the machine may be stuck and cause equipment obstacles. It needs to be cleaned regularly by the operators of each shift. Slot paper blocks that are narrower than the designed width into the slot will also increase the poor pressure resistance of the product
