Tobacco cabinet feeder exit control method and device

Abstract

The invention discloses a control method and device for coming out of a cabinet of a tobacco cabinet type feeding machine. The method comprises the steps of collecting states of photoelectric switches B1, B2 and B3, enabling B1 to be a high-material-level photoelectric switch, enabling B2 to be a medium-material-level photoelectric switch, and enabling B3 to be a low-material-level photoelectric switch; according to the states of the photoelectric switches B1, B2 and B3, dynamically adjusting current running frequency of a base belt motor M1 and current running frequency of an elevating belt motor M4; and repeatedly collecting the states of the photoelectric switches B1, B2 and B3 after predetermined time intervals. By detecting whether the high-material-level photoelectric switch, the medium-material-level photoelectric switch and the low-material-level photoelectric switch of limiting pipes, the running frequency of the base belt motor M1 and the running frequency of the elevating belt motor M4 are rapidly automatically adjusted, automatic speed adjustment in the whole process of the cabinet type feeding machine is achieved, and materials stable in flow are provided for a downstream mainframe device; the control method simultaneously guarantees that the device runs stably and continuously, starting and stopping frequencies are reduced, and labor intensity of operators is reduced to the largest extent.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a method and device for controlling the exit of a tobacco cabinet-type feeding machine. Background technique [0002] In the traditional tobacco shred production line, before the material enters the host equipment for further processing, there is usually a cabinet feeder to buffer the material so as to provide the host equipment with a stable flow of processed materials. by figure 1 Take the typical tobacco cabinet feeder as an example. After the material enters the cabinet feeder and reaches a certain buffer volume, its downstream main production equipment (such as tobacco feeder, shred dryer, etc.) starts to run. When the production operation After the personnel set the frequency of the bottom belt motor M1 of the cabinet feeder, the material moves to the exit roller with the bottom belt, and the movement of the roller motor M2 loosens the material, and then the material moves...

AI Technical Summary

Problems solved by technology

[0005] 1. When the operator sets the bottom belt frequency of the cabinet feeder too high, it is easy to cause material blockage at the outlet of the cabinet feeder and the inlet of the limit pipe;

[0006] 2. When the operator sets the frequency of the bottom belt of the cabinet feeder too low, it is easy to cause insufficient material supply to the electronic belt scale;

[0007] 3. The operator needs to manually adjust the running frequency of the bottom belt at all times according to the material distribution of the cabinet feeder. The operator has a heavy workload and has no time to pay attention to the operation of other key process parameters;

[0008] 4. The equipment between the cabinet feeder and the electronic belt scale is frequently started and stopped during the production process, resulting in large equipment loss
