Description
Technical Field
The invention belongs to the technical field of tobacco processing, and particularly relates to a tobacco leaf storage cabinet for discharging tobacco leaves on a tobacco shred production line.
Background
On a tobacco shred production line, the equipment for discharging tobacco leaves comprises a tobacco leaf storage cabinet. The tobacco leaf storing cabinet comprises cabinet plates positioned at two sides of the storing cabinet, a tobacco leaf conveyor positioned at the bottom of the storing cabinet, a distributing vehicle positioned at the top of the storing cabinet and a stirring roller positioned at the front end of the storing cabinet, wherein the tobacco leaf conveyor comprises a chain wheel and chain transmission mechanism driven by a motor and a conveying belt driven by the chain wheel and chain transmission mechanism, and tobacco leaves in the storing cabinet are conveyed out of the storing cabinet by the conveying belt. The distributing vehicle comprises two side plates and a belt conveyor arranged between the two side plates, wherein a walking motor for driving the distributing vehicle to reciprocate at the top of the leaf storage cabinet and a motor for driving a belt of the belt conveyor to rotate are arranged on the side plates. The three material stirring rollers are transversely and rotatably arranged between the two cabinet plates, are mutually parallel and are positioned in the same plane, and the uppermost material stirring roller is closest to the material distributing vehicle.
All motors of the leaf storage cabinet are controlled by PLC programming. When the tobacco leaf storage cabinet is used for distributing materials, the material distribution vehicle reciprocates at the top of the tobacco leaf storage cabinet under the control of the driving of the travelling motor and the travel switch (when the material distribution vehicle moves to the limit position at the front end of the tobacco leaf storage cabinet, a horizontal distance is reserved between the front end of the material distribution vehicle and the uppermost material stirring roller), and tobacco leaves piled on the belt of the material distribution vehicle are fully distributed in the tobacco leaf storage cabinet under the forward and reverse rotation of the belt of the material distribution vehicle. After the tobacco leaves are distributed, the distribution vehicle stops at the rearmost end of the leaf storage cabinet. Then, the tobacco leaf conveyor is started, the tobacco leaf storage cabinet starts to discharge, tobacco leaves in the tobacco leaf storage cabinet are conveyed to the front end of the Chu She cabinet at uniform speed, and simultaneously a stirring roller at the front end of the tobacco leaf storage cabinet rotates to stir the tobacco leaves out of the tobacco leaf storage cabinet in a dispersing mode, so that the tobacco leaves enter a tobacco leaf conveying line in a later procedure.
In the process that the tobacco leaves in the tobacco storage cabinet enter a tobacco leaf transmission line of a later procedure under the combined action of a tobacco leaf conveyor and a stirring roller (namely, the feeding of the tobacco storage cabinet), when the tail ends of the tobacco leaves in the tobacco storage cabinet are close to the stirring roller, the tobacco leaves are turned over backwards due to the reverse acting force of the pulling roller, so that the material layer of the tail ends of the tobacco leaves in the tobacco storage cabinet becomes thinner, the discharge amount per unit time becomes smaller, the discharge flow is reduced, and the material conveying uniformity is reduced (commonly called as tailing phenomenon), thereby leading to unbalanced and stable tobacco leaf amount supplied to the tobacco cutter in the later procedure, easily causing the shredding and running phenomenon and influencing the shredding quality of the tobacco leaves.
In order to solve the above problems, the following methods are generally adopted at present: 1. when the leaf storage cabinet only leaves the tailings, an operator enters the leaf storage cabinet and pushes tobacco leaf materials to the pulling roller through manual assistance; 2. when the tobacco leaves storage cabinet only leaves the tailings, the transmission speed of the tobacco leaf conveyor at the bottom of the tobacco leaves storage cabinet is increased, so that the flow of tobacco leaf materials in unit time is increased. However, because the conveyer belt of the tobacco leaf conveyer at the bottom of the leaf storage cabinet is always in a conveying state, and the pulling roller is also always in a rotating state, the operator enters the leaf storage cabinet and has great potential safety hazard. The adjustment of the conveying speed of the conveyor can only be carried out within a certain range, and the requirement of the discharge flow cannot be met due to the fact that the material layer of the tobacco tailing is too thin.

a group of second travel switches electrically connected with the PLC are arranged on the walking frame (5) and the push baffle shaft (15), when the push baffle is driven by a second gear motor to rotate to be vertical to the conveying belt (1), the second travel switches are triggered, the second gear motor (17) is controlled by the PLC to stop and the walking motor is controlled to start, and the speed of the walking motor for driving the material distributing vehicle to move towards the front end of the Chu She cabinet is higher than the conveying speed of the conveying belt at the bottom of the leaf storage cabinet;
a pressure switch (20) electrically connected with the PLC is arranged in the middle of the front surface of the baffle plate, when the baffle plate is propped against the tobacco leaves in the leaf storage cabinet, the pressure switch is triggered, and the PLC controls the traveling motor to slow down so that the moving speed of the distributing vehicle to the front end of the Chu She cabinet is consistent with the conveying speed of the conveying belt at the bottom of the leaf storage cabinet;
a group of third travel switches electrically connected with the PLC are arranged on the walking frame (5) and the pushing plate blocking shaft (15), and when the pushing plate blocking plate is driven by the second gear motor to rotate to be parallel to a plane formed by the material stirring roller, the third travel switches are triggered and the second gear motor (17) is controlled by the PLC to stop;
a group of fourth travel switches electrically connected with the PLC are arranged on the walking frame (5) and the push baffle shaft (15), and when the push baffle is driven by the second gear motor to rotate back to the lower side of the walking frame to be parallel to the walking frame, the fourth travel switches are triggered and the second gear motor (17) is controlled by the PLC to stop;
a group of fifth travel switches electrically connected with the PLC are arranged on the inner side of one side plate (3) of the material distribution vehicle and the traveling frame (5), and when the traveling frame retracts to the lower part of the bottom of the front end of the material distribution vehicle until the front end of the traveling frame is flush with the front end of the material distribution vehicle on a vertical surface, the fifth travel switches are triggered, and the first gear motor (19) is controlled by the PLC to stop.
2. The tailstock-preventing thinned-tobacco leaf storage cabinet of claim 1, wherein: the lower edges of the two side plates (3) of the material distribution vehicle are inwards bent into a turned-over edge (10) with 90 degrees, and the guide rail (16) is fixed on the turned-over edge.
3. The tailstock-preventing thinned-tobacco leaf storage cabinet of claim 2, wherein: the rear end of the flanging (10) is fixedly provided with a second limit baffle (18) perpendicular to the flanging, and when the walking frame (5) retracts to the lower part of the bottom of the front end of the cloth, the rear end of the walking frame is abutted against the second limit baffle when the front end of the walking frame is flush with the front end of the cloth on a vertical surface.
