Unwinding feeding automation-control device

Abstract

The invention discloses an unwinding feeding automation-control device. A photoelectric inductive switch is arranged above unwinding materials to detect the current material height and feed back a signal of the current material height to a frequency converter in a motor, and accordingly a transmission device is controlled to drive a rotating shaft to rotate at a high speed or a low speed to conduct unwinding feeding work of the unwinding materials. When the unwinding materials are numerous, the materials are sunken to the bottom, the height is low, the photoelectric switch is not triggered, and the motor controls the transmission device to unwind at the low speed; and when the unwinding materials are too few, the bevel height of the materials is increased, the photoelectric switch is triggered, the signal is transmitted to the frequency converter, and the motor controls the transmission device to unwind at the high speed. According to the unwinding feeding automatic-control device, unwinding feeding is conducted automatically, the magnitude of the feeding speed is adjusted automatically, starting and stopping of the device are controlled automatically, the labor cost is effectively reduced, the fault probability of unwinding work is decreased, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of slicer auxiliary feeding equipment, in particular to an automatic control unwinding and feeding device. Background technique [0002] The traditional feeding and unwinding of the slicer adopts a rotating shaft placed on a rack, and the cut whole roll of material is fixed on the rotating shaft, and the material is manually unloaded on demand. Using manual unwinding and feeding in this way, on the one hand, is a waste of human resources, and on the other hand, there are the following disadvantages: artificially controlling the feeding speed or frequency is prone to over-feeding or under-feeding or too fast or too slow, and too much unwinding If it is too fast, it will backlog up and affect the feeding; if the unwinding is too slow, too little and not timely, the material will be dragged, affecting the accuracy of the slice, resulting in too short or unqualified slices. [0003] In fact, in the process of unwinding a...
