Description
Technical Field
The invention relates to the technical field of tobacco processing, in particular to tobacco processing equipment and a control method of the tobacco processing equipment.
Background
On a cigarette cut-tobacco manufacturing line, a cabinet type feeder outputs materials through a lifting belt and a conveying belt at the bottom of a certain storage cabinet by a front cabinet type feeder of the tobacco cutter, the materials are output through the lifting belt and the conveying belt at a certain flow rate by the tobacco cutter, and the materials enter the cabinet type feeder for buffering by the lifting belt and the conveying belt, so that materials to be processed with stable flow rate are provided for a follow-up cut-tobacco drying host machine. In the batch production feeding process, materials after shredding are conveyed to a spreading belt by a lifting belt and then enter a temporary storage cabinet through the spreading belt.
The whole batch production feeding process can have the following defects:
1. in the existing production, the detection of materials in a cabinet feeder is usually realized through three pairs of opposite-type photoelectric tubes, and the photoelectric tubes are positioned in front of, in middle of and at the tail end of the cabinet to realize the detection of front cabinet, half cabinet and full cabinet of materials, so that the real-time detection capability of the existing material warehouse in the cabinet feeder is lacking.
2. In production, if a motor at the bottom of a storage cabinet of a front-end equipment such as a front cabinet type feeder of a shredder outputs a relatively fixed flow of material at a relatively fixed frequency all the time. This results in:
in production, when the storage capacity of materials in a feeding machine after shredding is more, the feeding flow is far greater than the discharge wire drying flow, the feeding machine after shredding is caused to frequently enter a full state of a cabinet, at the moment, before the feeding machine, a lifting belt and a conveying belt are frequently started and stopped, the feeding machine is frequently started and stopped to cause the increase of shredding and running sheets, the retention time of materials on the conveying belt is overlong, the stability of the moisture content and the temperature of cut tobacco is not benefited, the materials on the conveying belt are not uniform due to the fact that the materials are frequently started and stopped, and pits and the like appear in the cabinet.
In the production of the second place, when the storage capacity of materials in the feeding machine after shredding is less, the feeding flow is far less than the discharging and wire drying flow, the consumption of materials in the feeding machine after shredding is too fast, and risks such as interruption of production due to flow break exist.
The cause analysis is as follows:
the reason analysis is that the feeding and discharging drying flow of the cabinet type feeder after shredding is not matched, in the production process, the storage capacity of a material warehouse in the cabinet is expected to be in a dynamic stable ideal state after shredding, the feeding flow after shredding can be dynamically matched with the discharging drying flow, the feeding and discharging drying flow and the discharging drying flow are in a relatively balanced state, and the production continuity and stability are guaranteed. In actual production, the preamble equipment may be stopped due to faults or sundries treatment and other conditions, so that the material in the feeder is consumed too fast. Meanwhile, the follow-up equipment has fluctuation in processing flow due to the characteristics of water content and the like of materials, namely the discharge flow of the cabinet type feeder is relatively unfixed, and if the feed flow is far greater than the discharge wire drying flow, the production line is frequently started and stopped, otherwise, the production is interrupted.
At present, a material flow balance control strategy is lacked in the feeding process of the cabinet type feeder after shredding, so that the healthy operation of the preamble equipment is not facilitated, the quality of materials and the stability of the paving materials in the cabinet are influenced, and the processing technology of the follow-up main equipment is adversely affected.

calculating the material ratio X according to the following formula:
X＝(W-L)/W*100％,
wherein,
w: the distance from the first end to the second end of the material cabinet;
l: distance between the material end that detects the part and the second end of material cabinet.
8. The control method according to claim 7, characterized by further comprising: comparing the current material proportion X with the material proportion X before the set time t t And according to X and X t The frequency of the drive motor driving the second conveyor belt of the front feeder of the shredder:
when x=x t When the frequency n of the driving motor is equal to the real-time frequency n0 of the driving motor;
when X is>X t When the frequency n of the driving motor is controlled by the controller to be reduced by delta n from the actual frequency n 0;
when X is<X t When the controller controls the frequency n of the driving motor to be increased by an delta n from the actual frequency n 0.
9. The control method according to claim 8, wherein,
when the material ratio X is within a predetermined range, the t=t 1 The method comprises the steps of carrying out a first treatment on the surface of the When the material ratio is smaller than the preset range, the t=t 2 Wherein t is 1 >t 2 The method comprises the steps of carrying out a first treatment on the surface of the When the material ratio is smaller than the preset range, the t=t 3 Wherein t is 3 <t 2 。
10. The control method according to claim 9, wherein the predetermined range is 60% or less and 80% or less.
